In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although it is beneficial to adjust the angle of the backrest according to the comfort of the user, and by setting the spring frame, it is beneficial to have a buffering effect when adjusting the angle of the backrest, thereby reducing the vibration of the bed and the backrest, which is convenient to use and improves the comfort of use, the problem that there is no buffering function, it is easy to produce vibration and uncontrolled speed when adjusting the backrest, and the comfort of use is reduced. However, during use, the adjustable backrest of the traditional medical bed is to adjust the entire backrest. Due to the inconvenience of the patient, when the patient needs to lie flat, the angle of the backrest adjustment is limited, and medical staff are still needed to help the patient adjust the body. Moreover, the neck and head of the patient with inconvenience in movement are leaning on the backrest surface, and long-term inactivity causes the skin of the neck and head to ulcerate easily. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide an adjustable backrest for a medical bed to solve the problem that the current traditional adjustable backrest for medical beds is to adjust the entire backrest. Due to the patient's limited mobility, when the patient needs to lie flat, the angle of the backrest adjustment is limited, and medical staff are required to help the patient lie flat and place a pillow, which is not very convenient. Moreover, the neck and head of the patient with limited mobility lean against the backrest surface and are inactive for a long time, which leads to the technical problem that the skin of the neck and head is easily ulcerated.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing an adjustable backrest for a medical bed, including a headrest backboard, and also including:

[0006] Two support rods are respectively fixed on both sides of the top of the bed head back board;

[0007] A backrest adjustment mechanism is fixed between the two support rods, and the backrest adjustment mechanism includes a support plate body, and the support plate body is fixed between the two support rods;

[0008] Arc-shaped electric slide rails are installed on both sides of the front end of the support plate body, the front end of the arc-shaped electric slide rail is slidably connected with an electric slider, and a backrest body is fixed to one end of the electric slider away from the arc-shaped electric slide rail.

[0009] Preferably, a circular groove is provided at the front end of the backrest body, an air pump is installed inside the circular groove, the front end of the air pump is connected to a first air pipe, and the front end of the first air pipe is connected to an airbag support cushion.

[0010] Preferably, the rear end of the air pump is connected to a second air pipe, and the rear end of the second air pipe is connected to a circular groove.

[0011] Preferably, a bed bottom plate is fixed to the front end of the headrest board, and an arc-shaped electric slide rail is installed at the rear end of the top of the bed bottom plate.

[0012] Preferably, a footboard body is installed at the front end of the bed bottom board, and supporting foot rods are fixed on both sides of the bottom of the footboard body and the headrest backboard.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model arranges the arc-shaped electric slide rail at the position of the bedside through the combination of the arc-shaped electric slide rail, the electric slider and the backrest body. The arc-shaped electric slide rail can drive the electric slider and the backrest body to move in an arc shape. The backrest body can not only adjust the position of the backrest to facilitate the patient to lean on the bedside, but also move the backrest body to the position of the bed board and use the backrest body as a pillow so that the patient can lie flat. This solves the problem that the adjustable backrest of the traditional medical bed is to adjust the entire backrest. Due to the inconvenience of the patient's movement, when the patient needs to lie flat, the adjustment angle of the backrest is limited, and medical staff are also needed to help the patient lie flat and place the pillow, which is not very convenient technical problem.
