detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Referring to FIG. 1 , an air mattress includes a first air mattress L1 , a second air mattress L2 and a third air mattress L3 from top to bottom.

The first air cushion includes three independently separated air chambers, namely the first air chamber G1, the second air chamber G2 and the third air chamber G3, each air chamber surface is provided with a number of raised airbags after inflation, The airbags of each air chamber are interlacedly distributed on the surface of the first air cushion, forming a grid shape. All chambers are connected to the pneumatic system F4. The entire air cushion is driven by a pneumatic system, which uses a pre-set program to alternately inflate and deflate to distribute the weight of the patient who cannot move by himself and the part that is in contact with the air cushion. In addition, there are some small holes G4 in the third air chamber, which serve as channels for the escape of moisture, and play the function of keeping dry or warm under certain weather conditions.

In the head area, there is an extra layer of air cushion as pillow F1, which has the function of dispersing the pressure of different parts of the head, especially useful for patients who cannot control their head autonomously. The additional advantage of this inflatable pillow is that it can reduce the possibility of the patient's snoring through the cooperation of the implanted snoring sensor, and reduce the annoyance to adjacent patients, which is a very effective value-added function. In fact, this layer of air cushion can be implanted or installed with more additional sensors, and the patient's vital statistics and environmental data can be obtained remotely with mobile electronic devices through wired or wireless methods. Sensor data can also trigger default insufflation and deflation programs and/or mattress rhythms or mattress configurations to optimize clinical parameters.

The second air cushion L2 is composed of independent left air chamber G6 and right air chamber G7; the left and right sides of the second air cushion are respectively provided with an inflatable column G5, G8, and the inflatable column and the left and right air chambers are connected to the pneumatic system. A second air cushion is used to move the patient laterally. The air cushion can help the patient to lie on the left or right side, so that the patient can have a more suitable angle to breathe. In addition, users can control the frequency of movement through programming to meet different needs. Therefore, it can help the patient turn over and move without manpower, thereby reducing the chance of the caregiver suffering from symptoms such as back pain, and also reducing the need for extra cushions or pillows to support the patient's body, and greatly reducing the number of night shift caregivers people's needs. Moreover, these displacement movements do not rub against the patient's skin, reducing the possibility of accidental injury caused by human negligence or rough handling.

The third air cushion L3 is composed of backrest air chamber G9, buttock air chamber G10 and leg air chamber G11 from top to bottom. The three air chambers are inflated to different degrees to form a chair shape. Pneumatic system connection. This layer of air cushion can expand into the shape of a chair to help patients change their center of gravity or sitting posture, allowing patients to sit and eat at an angle, or to deal with bronchial problems caused by lying still for a long time. Its structure at the buttocks is recessed inwards to further lower the seat, replacing the function of ring pads or corrugated pads to reduce pressure on the buttocks.

Pneumatic system F4 includes controller and air pump.

The most prominent innovation of the utility model is that only three layers of air cushions are used to achieve multiple functions of moving the body, which reduces the demand for equipment, manpower and energy. While the use of structures similar to the first layer of air mattresses to treat, assist or manage bedridden patients has been around the world for decades, the use of "pillow" chambers that have ups and downs and use weak or strong support for the head instead of ordinary pillows , but it is a major innovation. The anti-snoring feature of the "pillow" chamber using the snoring sensor is also a novel and practical function. In addition, the patient’s vital statistics and environmental data provided by the additional sensor can be displayed on the mobile electronic device, which not only helps the caregiver to make a comprehensive assessment of the patient’s condition anytime, anywhere, but also allows the caregiver to remotely adjust the mattress. configuration.

The combination of this three-layer modular air mattress can be made with a minimum of five-layer construction (not including the small pieces of the pillow component), and it is possible to perform all of the basic mattress configurations listed above. This not only saves material costs but also reduces the weight of the device. Of course, for the flexibility of material usage and the maintenance of the whole mattress, these three-layer modular air mattresses can be composed of independent air mattresses joined by detachable buttons or clips to suit different prices and needs. Nevertheless, all layers are controlled by pneumatic systems.

When used in the hospital, you can choose the quick deflation function to allow the air cushion to quickly return to its flat structure, which is convenient for performing cardiopulmonary resuscitation when necessary.

The aeration unit may have a closed dedicated programmable logic control (PLC) system or be coupled to a device/module for manual/process control of duration, operation with air inflow and outflow, flow velocity, pressure sensing and control, And can reload control by wired or wireless remote device or download control program and/or schedule hook by software or application program.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
