Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1 to 6, an embodiment of the invention provides an air bag mattress, which comprises a bedstead 13, wherein a first bed board 11 and a second bed board 12 are arranged on the bedstead 13, the first bed board 11 is fixedly connected with the bedstead 13, the second bed board 12 is in running fit with the bedstead 13 through a rotating piece 14, a compression molding set 3 is arranged on the first bed board 11 and the second bed board 12, the compression molding set 3 is flatly distributed on the first bed board 11 and the second bed board 12, a supporting unit 2 is arranged on the upper surface of the compression molding set 3, the supporting unit 2 comprises an air bag 22, a mounting cylinder 21, a filling bag 211 and a filler 23 positioned in the filling bag 211, the filler 23 can be particles, the filling bag 211 is arranged on the mounting cylinder 21, the air bag 22 passes through the mounting cylinder 21 and is arranged in the filling bag 211, the filling bag 211 comprises an upper surface portion 2111 and a side portion 2112, the internal pressure of the air bag 22 can be changed, the air bag 22 changes along with the internal pressure change of the air bag 22, the supporting unit 2 can realize the fact that the upper surface of the filling bag 22 is in a flat state and the concave side surface of the filling bag 211 is in contact with the concave side 211 and the side of the filling bag 211 is in a vertical state, and the concave side 211 is deformed and is not in contact with the vertical side 211. The distance between the adjacent packing bags 211 cannot be too far, and if the distance between the adjacent packing bags 211 is too far, even if the packing bags 211 are raised at the supporting lower upper surface portion 2111 of the airbag 22, the side portions 2112 of the packing bags 211 cannot be in contact with each other, and at this time, the packing bags 211 and the side portions 2112 of the packing bags 211 do not press the gaps against each other, and thus the ventilation effect cannot be achieved, so that it is necessary that the adjacent packing bags 211 remain in contact with each other in the non-deformed state of the packing bags 211.

When the air pump 33 supplies pressure to the air bag 22 through the air-filling head 32 in the first stage, the internal pressure of the air bag 22 increases, the air bag 22 collapses the upper surface portion 2111 of the filling bag 211, the side portions 2112 of both sides of the filling bag 211 collapse inward, and a gap is generated between two adjacent filling bags 211, so that ventilation can be effectively performed to the sides of the filling bag 211, and at this time, the filling bag 211 can still provide partial support to the human body. The air flows through the gaps so as to take away moisture generated on the skin surface, so that the skin surface is kept dry, and pressure sores generated by the moisture of the skin surface are reduced;

when the air pump 33 supplies pressure to the air bag 22 in the second stage through the air charging head 32, at this time, the internal pressure of the air bag 22 is further increased relative to the internal pressure of the air bag 22 in the first stage, the air bag 22 makes the upper surface portion 2111 of the filling bag 211 flat, the side portions 2112 on both sides of the filling bag 211 keep vertical, at this time, the bottoms of the side portions 2112 of the plurality of filling bags 211 are contacted with the molding module 3 or the bed body, the part providing the main supporting function for the human body is the filling bag 211, and the air bag 22 only needs to keep the pressure of filling without deformation;

When the air pump 33 supplies pressure to the air bag 22 in the third stage through the air-filling head 32, and at this time, the internal pressure of the air bag 22 is further increased relative to the internal pressure of the air bag 22 in the second stage, and when the air bag 22 bulges the upper surface portion 2111 of the filling bag 211, the side portions 2112 on both sides of the filling bag 211 bulge outward, and at this time, a gap is formed between the skin and two adjacent filling bags 211, and the abutment between the side portions 2112 can make the abutment strength of the adjacent filling bags 211 larger, forming a hardened state, which can resemble the supporting force of a pallet.

The filling bag 211 filled with the particles can generate partial deformation and provide a stable supporting effect for a human body, gaps can be formed between the filling bag 211 and the surface of the human body and between the filling bag 211 through deformation while the human body is always supported, the deformation corresponds to the pressure of the air bag 22, and the effect of ventilation drying on the surface of the skin and between adjacent filling bags 211 is realized while the support is provided for the human body by utilizing the deformation of the air bag 22.

The sectional type folding of the sickbed is completed through the cooperation of the screw rod 15 and the hollow motor 16 in the prior art. The second bed board 12 is in a state of being attached to the bed frame 13 before being rotated. The screw rod 15 is rotationally connected with the bed board II 12 through the first connecting piece 17, the hollow motor 16 is rotationally connected with the bed frame 13 through the second connecting piece 18, when the hollow motor 16 works, a nut in the hollow motor 16 can push a screw rod to feed so as to push the bed board II 12 to rotate, and in the rotating process of the bed board II 12, the screw rod 15 and the hollow motor 16 can be rotationally connected with the first connecting piece 17 and the second connecting piece 18 along with the rotation of the bed board II 12, so that the change of the gesture is achieved. The hollow motor 16 is controlled to rotate reversely, so that the bed board II 12 can be controlled to rotate back to be attached to the bed frame 13.

The multi-section sickbed is a common plate bed for protecting the physical state of a patient, can uniformly support the body by using a rigid support, maintains the natural physiological curvature of the spine, and relieves the pain caused by lumbar disc herniation, lumbar muscle strain and the like. However, when the bed is too high in the degree of adhesion to the skin and is used in summer or by people with limited actions, the bed body is too hard and uncomfortable in body feeling, and discomfort is easily caused by too tight adhesion. While the alternative air cushion bed can improve some problems of the plate bed, the air cushion bed is less ventilated and is easy to wet, and patients with inconvenient movement are more prone to suffer from bedsores.

The invention combines the hard support of the board bed with the soft and adjustable characteristics of the air bag 22, and the pressure-making module 3 (which can be purchased in the market and only needs to be distributed into a specified box body, the shape of the box body can be directly designed into a first board 11 or a second board 12, namely, the air pump 33 replacing the first board 11 or the second board 12) pumps air, and the air pumped by the air pump 33 is connected with the air bag 22 through the air filling head 32 on the communicating pipe 322, so that the air is filled into the air bag 22. The air pump 33 inflates the air bag 22 in three stages, and the support provided by the air bag 22 to the filling bag 211 is different in different stages. The air pump 33 is supplied with pressure from the first stage to the second stage, the pressure of the gas supplied from the second stage to the third stage gradually increases, and the state of the filling bag 211 gradually collapses from the upper surface portion 2111 of the filling bag 211 to be flat, and bulges from the upper surface portion 2111 of the filling bag 211 to the upper surface portion 2111 of the filling bag 211. During the change of the shape of the balloon 22, the outer filling bag 211 is pushed to expand together. When the air pressure in the air bag 22 reaches the second stage of pressure supply, the air bag 22 can fully support the filling bag 211 and the filling material 23 in the filling bag 211, and the filling material 23 in the filling bag 211 can be a material with both hardness and dryness, such as a drying agent, quartz sand or pepper. These materials can enhance the air permeability of the support unit 2 while providing rigid support under the support of the air bag 22. The filling bag 211 is selectively made of a breathable material to enhance breathability of the patient's skin contact surface. The plurality of supporting units 2 which can provide the rigid support are spliced together, which is equivalent to the bed board forming a board bed, and achieves the rigid supporting function of the board bed.

When the particles of the particulate matter are directly reduced by more than 2mm, the friction force among the large particles is small, the particles are easy to gather to the lower position due to gravity or shaking after filling, for example, the bottom of the filling bag 211 is easy to be distributed unevenly, the upper surface portion 2111 is possibly softened due to sparse particles, the side surface portion 2112 is excessively hard due to dense accumulation, and the overall consistent hardness and shape cannot be maintained, the particles of the particulate matter are directly reduced by more than 2mm, and strong particle feel is brought, the filling bag 211 is used for contacting a human body, so that the pressure feeling is brought about, and the use experience is affected. It is necessary to use particles having a particle diameter of not more than 2mm as the filler 23.

As shown in fig. 1, the packing bag 211 bulges at the upper surface portion 2111 of the airbag 22 after the support, and the filler 23 inside the packing bag 211 flows toward the bottom of the packing bag 211, so that the side surface portion 2112 of the packing bag 211 bulges toward the periphery. However, the bulge of the side portion 2112 of the filling bag 211 is limited by the bulge of the side portion 2112 of the adjacent filling bag 211, the two adjacent filling bags 211 are pressed against each other, the bulge between the adjacent filling bags 211 further presses the side portion 2112, so that the filler 23 in the filling bag 211 cannot flow to the bottom of the filling bag 211, and meanwhile, the filler 23 tends to flow to the bottom of the filling bag 211, so that the bulge appears in the middle position of the filling bag 211, and the surrounding height is lower than that of the middle part, so that a recess is formed. So that two adjacent support units 2 are spliced together to form the ventilation duct 24. The moist skin surface of the patient lying for a long time is gradually dried by the presence of the air duct 24, thereby reducing the probability of bedsores caused by the moist skin surface of the patient.

Specifically, the molding die set 3 includes a housing 31, an air charging head 32, a communication pipe 322, and an air pump 33;

the shell 31 sets up the upper surface at bed board one 11 and bed board two 12, and the air inflation head 32 passes shell 31, is connected with the air inlet of gasbag 22, and communicating pipe 322 sets up in the inside of shell 31, and a plurality of air inflation head 32 sets up on communicating pipe 322, and air inflation head 32 passes through communicating pipe 322 and links to each other with air pump 33, and air pump 33 sets up in the outside of shell 31, links to each other with communicating pipe 322. The air pump 33 continuously supplies air to the communication tube 322, ensuring sufficient air in the communication tube 322, thereby preventing the air bag 22 from being depressed due to air leakage.

Specifically, the bottom of the air bag 22 is provided with the air film 221, and the length of the air film 221 when inflated is longer than the length of the mounting cylinder 21, and the air film 221 is inflated to pass through the mounting cylinder 21 and contact with the upper surface of the housing 31. When the gas inside the airbag 22 causes the airbag 22 to fully inflate, the gas then enters the interior of the airbag 22 from the inflation head 32, the airbag 22 does not continue to inflate, but rather causes the membrane 221 to inflate. After the air film 221 is lifted, it passes through the mounting tube 21 and abuts against the upper surface of the housing 31, thereby lifting the air bag 22. The bladder 22 lifted by the air film 221 is lifted with the filling bag 211. The controller 4 controls the jacking of the plurality of supporting units 2 on one side of the sickbed, so that the bed surface can generate an inclination angle, and the nursing staff can conveniently perform operations such as medicine feeding on a patient from the jacked side. The air film 221 can be toughened, so that after the air bag 22 is fully expanded, air is continuously blown in, and the air pressure in the air bag 22 is increased to expand the air film 221, so that the air bag 22 and the air film 221 are regulated in a staged manner. When the gas film 221 expands, the air head 32 is retracted into the housing 31 along with the expansion of the gas film 221, thereby preventing the air head 32 from being damaged by the expansion of the gas film 221.

The mounting cylinder 21 is not connected to the housing 31, and when the gas film 221 expands to pass through the mounting cylinder 21 and contact the upper surface of the housing 31, the mounting cylinder 21 is separated from the surface of the housing 31. If the mounting tube 21 is connected to the housing 31, the air bag 22 cannot be lifted up after the air film 221 is inflated, and the bed surface cannot be inclined, so that the mounting tube 21 is not connected to the housing 31.

Specifically, the inflation head 32 is communicated with the air bag 22 through a three-position electromagnetic valve 321, a controller 4 is arranged on the bed frame 13, the controller 4 is respectively electrically connected with the air pump 33 and the three-position electromagnetic valve 321, and the controller 4 regulates the pressure of the air bag 22 by controlling the three-position electromagnetic valve 321. The three-position solenoid valve 321 is matched with the controller 4 arranged on the bed frame 13 to independently control the air inlet and the air outlet of each air bag 22. The controller 4 can individually control a specific support unit through the three-position solenoid valve 321. When the patient feels the supporting unit 2 contacted with the apophysis is harder, the controller 4 can control the air pressure in the air bag 22 corresponding to the supporting unit 2, so that the air bag 22 returns to the concave state, and the supporting of the apophysis of the patient by the corresponding supporting unit 2 is reduced.

The controller 4 and the three-position electromagnetic valve 321 can control the pressure of the gas in the air bags 22 on a row by independently controlling a plurality of supporting units.

When the controller 4 controls the three-position electromagnetic valve 321 to regulate the gas pressure in the air bags 22, so that the gas pressure in the air bags 22 in a row is gradually increased from the first stage to the third stage, the state of the filling bag 211 gradually changes from the collapse of the upper surface portion 2111 of the filling bag 211 to the flat transition of the upper surface portion 2111 of the filling bag 211, and then from the flat upper surface portion 2111 of the filling bag 211 to the bulge transition of the upper surface portion 2111 of the filling bag 211, and the state of the supporting unit is gradually full, thereby forming a slope. The slope can further help the back posture of the patient to incline under the condition that the bed board II 12 inclines, so that a comfortable position is achieved.

The controller 4 is matched with the three-position electromagnetic valve 321, and can form a recess at any position of the first bed plate 11 and the second bed plate 12, so that ventilation of the skin of a patient without dead angle is realized.

Working principle:

When the bed board II 12 is not rotated and is attached to the bed frame 13 before adjustment is needed, the hollow motor 16 is started, the internal nut of the hollow motor drives the screw rod to feed to drive the bed board II 12 to rotate through the rotating piece 14, the screw rod 15 and the hollow motor 16 are connected with the first connecting piece 17 and the second connecting piece 18 in a rotating way to change the posture, the hollow motor 16 is controlled to rotate reversely, and the bed board II 12 can rotate back to be attached to the bed frame 13.

The air pump 33 supplies pressure to the air bag 22 through the air-filling head 32 in three stages, each of which is as follows:

In the first stage, the pressure in the air bag 22 is increased, so that the upper surface portion 2111 of the filling bag 211 is collapsed, the side surface portions 2112 on both sides are collapsed inwards, gaps are formed between the adjacent filling bags 211, ventilation is realized, partial support is provided, and skin moisture is taken away to reduce pressure sores.

In the second stage, the pressure of the air bag 22 is further increased, the upper surface portion 2111 of the filling bag 211 is flat, the side surface portion 2112 is kept vertical, the bottom of the side surface portion 2112 is contacted with the molding die set 3 or the bed body to form a main supporting component, and the air bag 22 only needs to maintain the pressure of the filling bag 211 without deformation.

In the third stage, the pressure of the air bag 22 is continuously increased, the upper surface portion 2111 of the filling bag 211 bulges, the side surface portion 2112 bulges outwards, a gap is formed between the skin and the adjacent filling bag 211, and the side surface portion 2112 abuts against the filling bag 211 so as to increase the abutting force of the filling bag 211 and form a hardened state, thereby providing a supporting force similar to a pallet.

And the bed surface inclination adjustment is that a plurality of supporting units 2 on one side of the sickbed are controlled by a controller 4, after the air bag 22 is completely inflated, the air bag 221 is inflated continuously, and passes through the mounting cylinder 21 to be abutted with the upper surface of the shell 31, so that the air bag 22 and the filling bag 211 are jacked up, the bed surface generates an inclination angle, and the nursing operation is convenient. The inflation head 32 will expand with the air film 221 back into the housing 31 to avoid damage.

Support adjustment when the patient feels the supporting unit 2 contacted with the apophysis harder, the controller 4 can control the three-position electromagnetic valve 321 corresponding to the supporting unit 2 to adjust the air pressure in the air sac 22, so that the air sac 22 returns to the concave state, and the support is reduced. In addition, the controller 4 is matched with the three-position electromagnetic valve 321, so that the air pressure in the air bags 22 in a row can be controlled to be gradually increased from the first stage to the third stage, the state of the supporting unit 2 is gradually full to form a slope, the back posture of a patient is helped to be adjusted to a comfortable position when the bed board II 12 is inclined, and the concave can be formed at any position of the bed board I11 and the bed board II 12, so that dead angle-free ventilation of the skin of the patient is realized.
