Description

Backplate slider

Technical Field

The utility model relates to the technical field of medical beds, in particular to a back plate sliding device.

Background

Most of the medical beds in the market can realize the change of sitting and lying postures at present. The medical bed can also lift the back of the patient on the premise of having the basic lying function, namely the medical bed has the back lifting function.

When the medical bed lifts the back of a patient and enables the patient to sit up, the back of the patient is leaned on the back plate of the medical bed, the back plate and the back of the patient move relatively, and discomfort is easily caused to the back of the patient.

The medical bed shown in the attached figure 1 comprises a medical bed body, a shank supporting plate, a thigh supporting plate, a hip supporting plate and a back supporting plate, wherein the shank supporting plate, the thigh supporting plate, the hip supporting plate and the back supporting plate are sequentially arranged on the medical bed body, the back supporting plate and the hip supporting plate are hinged, a lifting mechanism is further arranged on the medical bed body, the lifting mechanism is used for overturning the back supporting plate, a patient can sit up when the back supporting plate is overturned, and then the back function is realized.

As shown in the attached figure 2, when the patient sits up by using the medical bed shown in the attached figure 1, the hinge point of the back support plate and the hip support plate is the back-up rotation center, and the hip joint of the human body is the back rotation center. Because the back-rising rotation center and the back rotation center are not concentric, when the back support plate drives the human body to rise and sit, the contact surface of the back support plate and the back of the patient can slide relatively. For patients with back trauma or back pressure sores, the friction caused by such relative sliding can cause secondary damage to the back trauma or back pressure sores.

If the back of the human body and the back supporting plate can not slide relatively, the human body slides towards the bed tail. In case the back backup pad is set level, the human body mainly leans on the buttock to exert oneself in the buttock backup pad, and patient's back is less with back backup pad frictional force, therefore the patient can not follow the back backup pad and reset to the position before the seat.
