Description

Multifunctional mattress device

The present invention provides a multifunctional mattress device that combines the functions of automatic assisted turning over and automatic excretion and cleaning into a mattress to reduce the need for care manpower, reduce purchase costs, and prevent bedsores and diaper rash.

As the global population grows, it is also welcoming an aging society and a super-aging society. The World Health Organization points out that in the next 30 years, the elderly population over 65 will grow exponentially, which will not only test the social welfare capabilities and pension systems of various governments, but also the tolerance of medical systems and medical manpower. The World Health Organization also statistics show that in 2030, the world will need about 9.9 million surgeons, nurses and caregivers. It can be seen that the shortage of medical manpower is also one of the problems that need to be solved.

In terms of the long-term care system, when the skin or subcutaneous tissue of long-term bedridden patients is under pressure for a long time, the blood flow in the compressed area will begin to decrease and become blocked, causing inflammation, hypoxia, and gradual necrosis of cells in the compressed area, resulting in skin, subcutaneous tissue and muscle decay and wounds. This is a common bedsore for long-term bedridden patients. In addition, long-term bedridden patients may choose to wear diapers because they cannot get out of bed. If the diapers are not changed in time, it is easy to cause diaper rash. These two are skin symptoms. Some bedsores are deep enough to reveal bones. Debridement requires scraping bones and digging out flesh, which is extremely painful. In order to prevent bedsores and diaper rash, a dedicated person is needed to provide 24-hour care. Not only must the patient be turned over on time, and given timely assistance such as going to the toilet or changing diapers, but the caregiver must also constantly use his or her own strength to turn over the patient who has been bedridden for a long time. This is labor-intensive and stressful. Long-term care work is boring but cannot be sloppy, and often makes the caregiver physically and mentally exhausted.

Although there are turning beds on the market, the above turning beds have the following problems and deficiencies when used and need to be improved:

There are two main types of electric turning beds. One type uses the turning and lifting of the bed board to drive the special mattress to deform in order to achieve the purpose of turning over or getting up. This type of electric bed is commonly seen in medical institutions and usually requires manual operation by caregivers. It can only solve the problem of laborious operation. The design of using the bed board to drive the bed means that consumers must purchase the entire bed set, which greatly increases the purchase cost. However, families who need to buy turning beds usually already have their own bed frames, so they also need to remove the original bed frames, which is very troublesome.

The second type is a turning mattress, which usually uses an electric frame to tilt and deform the mattress. The frame will greatly reduce the comfort of the mattress, or the mattress will be thickened to maintain comfort. However, a mattress that is too thick will reduce its allowable tilt range and affect the turning effect. The cost of this type of mattress is not less than that of a turning electric bed with a bed frame.

In addition, the price of a rolling air mattress is significantly lower than that of an electric bed, but its lying comfort is also much inferior. For people who need to lie in bed for a long time, comfort is an important point that cannot be ignored.

Even if a turning bed is used to assist in turning over, long-term bedridden people still have the problem of being unable to get out of bed to defecate, and still need the assistance of caregivers. Whether it is the use of diapers, urine pots, bedpans, or the cleaning of bedridden people after defecation, manpower is required. It is known that holes are dug in the mattress, and various excretion assistance devices or cleaning assistance devices are installed under the mattress or on the bed frame, but they all need to be combined with the bed frame or still need to be handled manually by personnel, which is still very inconvenient.

Therefore, how to solve the above-mentioned problems and deficiencies in usage is the direction that the applicant of this invention and related manufacturers engaged in this industry are eager to study and improve.

Therefore, in view of the above-mentioned deficiencies, the applicant of this invention has collected relevant information, evaluated and considered various aspects, and based on many years of experience in this industry, after continuous trials and modifications, has finally designed a multifunctional mattress device that combines the functions of automatic assisted turning over and automatic excretion and cleaning into a mattress, thereby reducing the need for care manpower, reducing purchase costs, and preventing bedsores and diaper rash.

The main purpose of the invention is to use the pushing mechanism to automatically assist the bedridden person to turn over, and to use the opening and cleaning device to allow the bedridden person to defecate safely without getting out of bed, thereby preventing the bedridden person from bedsores or diaper rash and reducing the burden on caregivers.

Another main purpose of the present invention is to integrate the push mechanism, cleaning device, power supply line and water supply pipeline into the mattress body, which does not affect the comfort and structural complexity of the mattress body, and can also avoid the purchase of a bed frame and reduce the purchase cost.

To achieve the above-mentioned purpose, the main structure of the present invention includes: a mattress body, two pushing mechanisms, a driving device, a control module, an opening, a cleaning device, a sensing element, a power supply assembly, a power supply line assembly, a power supply unit, a water supply assembly, a water supply pipeline, and a water supply unit, wherein the pushing mechanism is arranged in the mattress body and pushes toward the surface of the mattress body, the driving device is connected to drive the pushing mechanism, and the control module information The driving device is connected to control the action mode of the pushing mechanism. The opening is arranged on the mattress body. The cleaning device is arranged in the mattress body and is located on one side of the opening. The sensing element is arranged on one side of the opening to automatically start and close the cleaning device. The power supply wire set is arranged in the mattress body and electrically connects the driving device and the cleaning device. The power supply part is connected to the power supply wire set. The water supply pipeline is arranged in the mattress body and is connected to the cleaning device. The water supply part is connected to the water supply pipeline.

When the user uses the new model as a mattress for long-term bedridden people, since its power supply components and water supply components are both arranged in the mattress body, a mattress body has all the following functions, and there is no need to purchase a bed frame, so the purchase cost is relatively low. When in use, the control module can be used to set the driving device to control the pushing mechanism to massage and relieve pressure or to push and turn the body over, which helps the blood circulation of bedridden people and avoids long-term pressure, thereby preventing bedsores. Bedridden people can use the opening to defecate directly without getting out of bed, and then the sensor element detects the movement of dirt to automatically start and close the cleaning device to perform cleaning work after defecation to ensure hygiene issues and save diaper costs, eliminate the risk of diaper rash, and save care manpower.

The above technology can solve the problems of turning over beds that users who use bed boards to turn over need to purchase extra bed frames, which is costly. The turning over method that uses an electric frame to tilt the mattress will reduce the comfort of the mattress and affect the tilting range. The cost is also not low. Compared with ordinary mattresses, turning over air cushion beds have obvious comfort problems. In addition, the above mattresses cannot solve the problem of inconvenient excretion. Even if holes are dug in the mattress, various auxiliary devices for excretion or cleaning must be combined with the bed frame, which is still very inconvenient. The above advantages are practical and progressive.

In order to achieve the above-mentioned purpose and effect, the technical means and structure adopted by the present invention are described in detail in the following figure for the preferred embodiment of the present invention, and its features and functions are explained for complete understanding.

Please refer to the first figure, which is a three-dimensional perspective view of a preferred embodiment of the present invention. It can be clearly seen from the figure that the present invention includes:

A mattress body 1;

The second pushing mechanism 2 is disposed in the mattress body 1 and is used to push toward the surface of the mattress body 1;

A driving device 3 is connected to the thrust mechanisms 2 via a diverter valve 21;

A control module 4 is informationally connected to the driving device 3 to control the action mode of the pushing mechanism 2. The control module 4 is informationally connected to a timing unit 41, which allows each pushing mechanism 2 to operate in turn at a fixed interval to push the side of the bedridden person and assist him/her in turning over;

An opening 11 is provided on the mattress body 1;

A cleaning device 5 is disposed in the mattress body 1 and located on one side of the opening 11, and has at least one sensing element 51 disposed on one side of the opening 11 for automatically starting and closing the cleaning device 5;

A power supply assembly 6, comprising a power supply line set 61 disposed in the mattress body 1 and electrically connected to the driving device 3 and the cleaning device 5, and a power supply unit 62 connected to the power supply line set 61; and

A water supply assembly 7 includes a water supply pipeline 71 disposed in the mattress body 1 and connected to the cleaning device 5, and a water supply portion 72 connected to the water supply pipeline 71.

The mattress body 1 is one of a spring mattress, a foam mattress, or a latex mattress. This embodiment takes a foam mattress as an example. Therefore, the structure set in the mattress body 1 is to hollow out the foam corresponding to the volume of the structure and bury it inside, or to squeeze the foam to vacate the space for setting the structures. The pushing mechanism 2 is a long strip sheet, or is composed of a plurality of columns arranged side by side. This embodiment takes a long strip sheet as an example. The driving device 3 is a hydraulic rod 31 combined with a hydraulic pump 32, a pneumatic rod combined with an air pump, or a lifting mechanism combined with a motor. One of them, in this embodiment, is a hydraulic rod 31 combined with a hydraulic pump 32 as an example; the control module 4 is one of a controller, an operation panel, or a mobile application, and in this embodiment, an operation panel is used as an example; the opening 11 is used as a perforation as an example; the cleaning device 5 is used as a water spray head as an example; the sensing element 51 is used as an infrared blocking sensor as an example, so there are corresponding transmitters 511 and receivers 512 on both sides of the opening 11; the power supply part 62 is used as a plug as an example; the water supply part 72 is used as a water valve as an example. However, the corresponding types of the above-mentioned components are only examples of preferred embodiments. Any types with the same functions are within the scope of the present invention and are not limited to the above-mentioned examples.

Through the above description, the structure of this technology can be understood. According to the corresponding coordination of this structure, the two functions of automatic assisted turning over and automatic excretion and cleaning can be combined in the mattress to achieve the advantages of reducing the need for care manpower, reducing the cost of purchasing and using diapers, and preventing bedsores and diaper rash. The detailed explanation will be given below.

Please refer to the first to fifth figures at the same time, which are three-dimensional perspective views to cleaning schematic views of the preferred embodiments of the present invention. When the above components are assembled, it can be clearly seen from the figures that the present invention is a mattress body 1 in appearance, and does not need to match a specified style or a dedicated bed frame. Therefore, when there is a long-term bedridden person at home, the user only needs to buy a mattress body 1 of the present invention, and does not need to buy or replace the bed frame together, thereby saving the cost of the bed frame and the process of replacing the old bed frame. It can be used directly after buying it home, which is very convenient.

Since the present invention has the functions of automatic assisting turning over and automatic excretion and cleaning, it is necessary to supply water and electricity to the mattress body 1. However, since the pushing mechanism 2, the cleaning device 5, the power supply line set 61 and the water supply pipeline 71 are all integrated in the mattress body 1, all installation operations are completed by placing the mattress body 1 in position and connecting the power supply part 62 and the water supply part 72 exposed outside the mattress body 1 to the main power socket and the water source respectively. There is no need to configure pipelines, and the beauty of the mattress body 1 or the indoor space will not be affected. In addition, although the pushing mechanism 2, the cleaning device 5, the power supply line set 61 and the water supply pipeline 71 are all integrated into the mattress body 1, these structures are buried in the space of the foam corresponding to the size of the structure hollowed out in the mattress body 1, or in the space vacated by squeezing the foam, and in practice, the mattress body 1 has a cushioning comfort layer 12 for the bed occupant to directly contact, and below the cushioning comfort layer 12 is a structural setting layer 13 for setting the pushing mechanism 2 and other structures, so it will not affect the comfort of the bed. Similarly, when pushing, the pushing mechanism 2 will also use part of the cushioning comfort layer 12 to directly contact the bed occupant.

In actual use, most people who have been bedridden for a long time are those with limited mobility or seriously ill patients who are not allowed to change their posture at will. They may still be able to move their hands, but it is difficult for them to turn over by themselves, and they cannot get out of bed to defecate by themselves. Therefore, people who have been bedridden for a long time are a high-risk group for bedsores and diaper rash. The present invention can set the action mode of the driving device 3, including the rising speed and the rising height, through the control module 4. The shunt valve 21 controls the action timing of the two groups of pushing mechanisms 2, or further cooperates with the timing unit 41 to set the retention time after the upward pushing. Each time, one of the pushing mechanisms 2a is activated for pushing, and after the retention time, it is lowered and replaced by the other pushing mechanism 2b to push, so that each pushing mechanism 2 can be activated in turn at a fixed interval to push the side of the bedridden person and assist him to turn over. Since the surface of the pushing mechanism 2 is still part of the mattress body 1, the user will not feel the presence of the pushing mechanism 2 when lying on the mattress body 1 normally. In fact, the pushing mechanism 2 only pushes the user upward by about 5cm~10cm, and there is no need to tilt the user's body to more than 30 degrees. According to research reports, if a patient uses a decompression mattress or a pressure-dispersing mattress, the patient's turning over time is extended from once every two hours to once every four hours. The probability of bed sores is not significantly different from turning over once every two hours on an ordinary mattress. According to Japanese scholars, the average body pressure of a general patient lying on his back is 40mmHg~45mmHg. g, and at each time point within two hours, only a small pillow is used. After the patient's upper body is lifted to the side in a supine position, the pillow is inserted and placed under the lower edge of the shoulder blades in the upper body and behind the thighs in the lower body. This can reduce the average body pressure by about 10 mmHg. Therefore, 1 to 2 times a day can improve blood flow, stimulate muscles, and achieve the goal of preventing muscle atrophy and treating ulcers. It can be seen that the purpose of using a turning mattress is not to really let the bedridden person turn over significantly, but to reduce his average body pressure. Therefore, the present invention uses a simple pushing mechanism 2 to slightly act on the local position of the bedridden person's body to transfer the body's pressured parts, and can cooperate with the bedridden person's habits to control the module 4 to set the rising speed and rising height of the driving device 3, which can effectively avoid affecting the bedridden person's sleep and reduce the feeling of falling caused by the large tilt of the mattress. At the same time, through the automatic turning action, it can reduce the caregiver's pressure and prevent the bedridden person from inducing bedsores.

In addition, in response to the excretion needs of long-term bedridden people, the common care method is to install a catheter, use a urinal to collect urine, and have the caregiver insert a bedpan to collect feces. When the bedridden person needs to defecate, the caregiver must provide assistance as soon as possible, otherwise the bedridden person will have to wear a diaper. The present invention is to set an opening 11 on the mattress body 1, and a drainage receiving part 111 is set below the opening 11. The position of the opening 11 corresponds to the pelvic cavity of the bedridden person. The drainage receiving part 111 can be an existing bedpan or other container, and the bedridden person can wear clothes that are convenient for defecation, such as surgical gowns, open-crotch pants, etc. Usually, just place an drainage receiving part 111 in the opening 11, and the bed board or floor below the mattress body 1 supports the drainage receiving part 111. When the bedridden person has the urge to defecate or urinate, he or she can directly defecate toward the opening 11, without notifying the caregiver or asking for the caregiver's assistance, and without having to wait until the caregiver arrives to defecate. 111 is adopted, and there is no need to worry about dirtying the mattress body 1. In addition, by using the setting of the sensing element 51, when the bed occupant defecates, the waste will be sensed by the sensing element 51 when it falls into the excrement receiving portion 111. Then, when the sensing element 51 cannot sense the waste again, the cleaning device 5 will be automatically activated. The cleaning device of this embodiment Reference numeral 5 is a retractable water spray head which is retracted in the mattress body 1 when not in operation. When activated, it extends to the center of the opening 11 to spray water by water pressure to wash the body of the bedridden person without the assistance of a caregiver. This can avoid the body pain or risk of pulling the tube caused by changing posture for defecation and can also reduce the manpower burden of the caregiver. When the sensing element 51 senses the dirt, it will also transmit its sensing information to the control module 4 immediately, and the control module 4 will notify the caregiver. The notification method can be sound and light warning, or message notification. The control module 4 of this embodiment is an operation panel set on one side of the mattress body 1, so it can notify the nearby caregiver by sound and light warning, or send a message notification by connecting the control module 4 to the network. In this way, when the caregiver finds the notification alarm, he does not have to rush to help immediately. He only needs to take time to check later and take away the excrement storage part 111 for cleaning. The whole process is safe and hygienic, saves a lot of diapers, promotes environmental protection, and relieves the pressure of the caregiver to help with excretion in time.

Please refer to FIG. 6, which is a massage diagram of another preferred embodiment of the present invention. It can be clearly seen from the figure that the present embodiment is similar to the above embodiment, except that the control module 4 has a massage unit 42 for controlling the driving device 3 to perform one of the vibration, rotation, or swinging movements, and each of the pushing mechanisms 2 in the present embodiment is composed of a plurality of columns arranged side by side, and each of the pushing mechanisms 2 is controlled by the driving device 3. The control module 4 of the embodiment is implemented as a wired controller, and the massage unit 42 is a button or a driver program on the control module 4. When the user uses the massage unit 42 to start the massage mode, the drive device 3 changes from a simple vertical lifting action to a vibration, rotation, or swinging action after rising to a fixed position. This embodiment uses the vibration action as an example, but the action mechanism of various action modes can refer to the mechanism in the existing massage field, and will not be described in detail. In this way, in addition to the function of automatic turning over, the pushing mechanism 2 can also provide a simple massage effect, which can not only make the bedridden person more relaxed, but also help stimulate blood circulation and prevent the occurrence of bedsores. It can also improve the grade of the mattress body 1, so that consumers have more choices and help marketing promotion.

Please refer to the seventh figure at the same time, which is a cleaning schematic diagram of another preferred embodiment of the present invention. It can be clearly seen from the figure that this embodiment is similar to the above embodiment, except that the cleaning device 5 has a flushing element 52 and a drying element 53 arranged on one side of the flushing element 52. The flushing element 52 is a retractable water spray head, and the drying element 53 is a retractable blowing mechanism. In this way, the bedridden person can use the flushing element 52 to clean After the dirty part is removed, the drying element 53 can be further used to dry the body, which can not only clean more completely and conform to the practical cleaning process, but also make the bedridden person feel more comfortable after defecation. In this embodiment, the cleaning device 5 is simultaneously connected to the control module 4, so that the caregiver or bedridden person can set the action details of the flushing element 52 and the drying element 53, such as water pressure strength, flushing angle, blowing strength, blowing temperature, etc., making it more convenient to use.

Please refer to FIG. 8, which is a schematic diagram of another preferred embodiment of the present invention. It can be clearly seen from the figure that the present embodiment is similar to the above-mentioned embodiment, except that at least one functional sensor 14 connected to the control module 4 is provided on the mattress body 1. The functional sensor 14 is one of a pulse detector, a blood pressure detector, a pressure sensor, a temperature sensor, an image sensor or a weight sensor, or a combination thereof. The functional sensor 14 can contact different detection items according to different detection items. Physiological parameters can be obtained in a non-contact manner, thereby obtaining various physiological information for a long period of time during sleep without being noticed, and the physiological information can be recorded in the control module 4, without spending a lot of time and energy cooperating with professional caregivers to attach detection instruments for detection and recording, which is more conducive to the care of bedridden people and reduces the workload of caregivers. The control module 4 of this embodiment takes a mobile application as an example, allowing caregivers to use personal mobile phones or tablets to view relevant physiological information at any time.

However, the above is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the contents of the present invention's specification and drawings should be included in the patent scope of the present invention and should be stated.
