The diagnosis and treatment plan for new coronavirus infection points out that medium, severe and critical cases with high risk factors for severe disease and rapid disease progression should be given standardized prone position treatment, and it is recommended that no less than 12 hours a day. The principle is that when lying on your back, due to the effect of gravity, sputum accumulates at the bottom of the lungs, which is not conducive to drainage toward the airway; the dorsal side has a richer blood supply but insufficient ventilation, resulting in an imbalance in the ventilation-blood flow ratio, and some dorsal lung lobes are affected by gravity and The heart is compressed, the lung volume is reduced, and ventilation is reduced. When lying prone, the dorsal alveoli reopen, ventilation increases, and the ventral alveoli can still open, improving the ventilation-blood flow ratio.

Proning is an unconventional position. Lying prone for a long time is obviously very uncomfortable for patients, difficult to maintain, and prone to pressure sores. Therefore, you can adopt a variety of specific positions when lying prone, and change positions once in a while. In order to help patients maintain these postures and improve comfort, applicants currently often use soft pillows under the patient's body. Some specific postures are as follows.

Semi-recumbent position: The patient lies on his side, with soft pillows placed under the patient's head and chest, and soft pillows next to his legs. One leg is bent and placed on the soft pillow. Leisure position: The patient lies prone, with a soft pillow under the chest and no soft pillow under the head. The patient can raise his head and read mobile phones and books; this position is suitable for patients with mild symptoms and good self-care ability.

Although the above postures are beneficial to disease recovery and improve patient comfort, they require multiple soft pillows, which are difficult to store; and after a patient uses them, the soft pillows need to be cleaned and disinfected, so the hospital needs to increase the amount of soft pillows in stock and increase the number of pillows. Increase the cleaning and disinfection workload.

It can be seen that the utility model can assist the patient to lie prone in multiple postures and improve the patient's comfort when lying prone.

The utility model is placed on the hospital bed and under the bed sheet. When in use, some of the air bags 11 are inflated. When not in use, there is no need to store them specially. The air bags 11 are not inflated, which is more convenient to use than a soft pillow. Since it is located under the bed sheet, the utility model does not require special cleaning and disinfection after a patient uses it, and does not increase the workload of cleaning and disinfection.

The cushion body 1 can be made of existing air mattress materials. The significance of the U-shaped shape of the head air bag 11a is that its concave portion can correspond to the patient's mouth and nose, allowing space for the mouth and nose, and the periphery of the concave portion can support the patient's cheeks and forehead, so that the patient can face downward, and the filling air bag 11b is not inflated at this time. . The function of the filling air bag 11b is to fill the recessed part of the head air bag 11a after inflating. The head air bag 11a and the filling air bag 11b together form a conventional square air bag, which can fully support the patient's head and is suitable for situations where the patient does not face downward.

Each air bag of the present utility model needs to be able to be inflated and deflated independently, and the inflating device 2 is used to realize this function. The specific structures of the cushion body 1 and the inflating device 2 are preferably as follows: the cushion body 1 is provided with a cushion body air pipe 12, which is arranged in one-to-one correspondence with each air bag 11; the inflating device 2 includes an air pump 21, an inflating main pipe 22, and an inflating branch pipe 24 , exhaust main pipe 25 and three-way valve 23, the inflatable main pipe 22 is connected to the air pump 21, the number of inflatable branch pipes 24 and three-way valves 23 is the same as the number of cushion body air pipes 12; the three interfaces of the three-way valve 23 are respectively connected to the inflatable main pipe 22 , the exhaust main pipe 25 is connected to an inflatable branch pipe 24, and the three-way valve 23 can control the inflatable branch pipe 24 to be connected to the inflatable main pipe 22, or the inflatable branch pipe 24 to be connected to the exhaust main pipe 25, or the inflatable branch pipe 24 to be closed; a cushion body air pipe 12 and An inflatable branch pipe 24 is connected.

In this way, when some air bags 11 need to be inflated according to the prone position, the air pump 21 is turned on, and the three-way valve 23 corresponding to these air bags 11 is activated to connect the inflating branch pipe 24 with the inflating main pipe 22, so that these air bags 11 can be inflated. After the inflation is completed, the three-way valve 23 is activated to close the inflation branch pipe 24, so that the gas in the airbag 1 will not be discharged, and the airbag 11 will remain inflated. When the air bag 11 needs to be deflated, the three-way valve 23 is activated until the inflation branch pipe 24 is connected to the exhaust main pipe 25, and the gas can be automatically discharged. If a small amount of gas is not discharged, just press the air bag 11 lightly.

The three-way valve 23 can achieve the required functions by using a common valve core rotary valve. The details are shown in Figure 6. The states of the three-way valve 23 from left to right are that the inflation branch pipe 24 is connected to the inflation main pipe 22. The branch pipe 24 is connected with the exhaust main pipe 25, and the charging branch pipe 24 is closed.

The cushion body air pipe 12 and the inflatable branch pipe 24 are connected in a one-to-one correspondence. The specific connection method can be a conventional pipe-to-tube connection method. By separating the connection between the two, the cushion body 1 and the inflatable device 2 can be separated. In order to facilitate the connection and separation of the cushion body air pipe 12 and the inflatable branch pipe 24, the specific design of the cushion body 1 and the inflatable device 2 can be further optimized as follows: the inflatable device 2 includes a device shell 26 and a shell air pipe joint 27, an air pump 21, and an inflatable main pipe 22 , the inflatable branch pipe 24, the exhaust main pipe 25 and the three-way valve 23 are all arranged in the device shell 26, the shell air pipe joint 27 is connected to the device shell 26, and each inflatable main pipe 22 is integrated on the shell air pipe joint 27; pad The body 1 includes a cushion body air pipe joint 13, and each cushion body air pipe 12 is integrated on the cushion body air pipe joint 13; the cushion body air pipe joint 13 is connected to the shell air pipe joint 27.
