Description

Nursing bed with back function

technical field

The invention relates to the technical field of medical equipment, in particular to a nursing bed with a back-lifting function.

Background technique

In hospital and home nursing facilities, the elderly or patients (hereinafter referred to as patients) who are bedridden for a long time due to the inconvenience of lower limbs usually use nursing beds. The existing nursing beds often also have a back-lifting function. The back movement is simply to tilt the support plate on the back of the nursing bed, so that the patient can achieve the effect of lifting the back, but most of the patients who use the nursing bed are paralyzed or have difficulty moving. The bed provides fit and support for the patient's waist, legs and feet. When nursing the back of the bed, the patient will feel tired from sitting in a short time, and the patient cannot keep the back posture for a long time, and the patient's body is easy to slide down. Increase the patient's physical discomfort.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide a nursing bed with a back-up function with reasonable structure and convenient use, which improves the comfort of the patient's body when the patient maintains the back-up posture.

It is hinged with the back support plate. The connecting rod assembly includes a first connecting rod and a second connecting rod. One end of the first connecting rod is fixedly connected to the foot support plate, and the other end of the first connecting rod is hinged with one end of the second connecting rod. The other end of the connecting rod is hinged with the bed frame, the leg electric push rod is hinged on the bed frame, and the push rod end of the leg electric push rod is hinged with the middle part of the second connecting rod.

As a preferred option of the nursing bed with the function of lifting the back, the lifting mechanism further includes at least one set of waist limit components, the waist limit components include limit hooks, one end of the limit hooks is hung on the waist support plate, and the bed The rack is provided with a waist-shaped hole matched with the limit hook, the length direction of the waist-shaped hole is consistent with the vertical direction, and the limit hook restricts the turning angle of the waist support plate relative to the buttock support plate to be smaller than the turning angle of the back support plate relative to the buttock support plate.

As a preference of the nursing bed with the function of lifting the back, the electric back push rod is hinged in the bed frame at the lower side of the waist support plate, and the push rod end of the electric waist push rod is hinged with the lower end surface of the back support plate. When it is pressed, the back electric push rod pushes the back support plate obliquely to turn over, and then drives the waist support plate to turn over synchronously.

As a preferred option of the nursing bed with a back-lifting function, in the initial state, the upper end surfaces of the headrest, back support, waist support, buttocks support, leg support and foot support of the bed board mechanism are all in on the same level.

When the nursing bed with the function of lifting the back moves, the electric back push rod drives the hip support plate and the waist support plate to turn over. Move in the waist-shaped hole; after that, the limit hook moves to the upper end of the waist-shaped hole of the limit plate, and the waist support plate no longer flips under the action of the limit hook, but the back support plate is under the action of the waist electric push rod. Continue to turn over, the limit hook limits the turning angle of the waist support plate relative to the hip support plate to be smaller than the turning angle of the back support plate relative to the buttock support plate, the patient is in a sitting posture when the hip support plate and the waist support plate are turned over, and the hip support plate and the waist support plate are turned over. The support plates are closely attached to the back and waist of the patient respectively; the electric push rods of the legs and feet act as the link assembly, the leg support plates are turned down and approached to the direction of the bed frame, and the foot support plates are always kept horizontal; the electric push rod of the headrest drives the head The front pillow plate is flipped relative to the back support plate, which is convenient to adjust the head angle of the patient.

The beneficial technical effects of the invention are as follows: the structure is reasonable and the use is convenient; when the nursing bed with the function of raising the back, the patient maintains the posture of raising the back to improve the comfort of the patient's body, and ensures the fit of the waist and the legs of the patient. to avoid the patient's body sliding after holding the back-to-back position for a long time.
