Labor-saving transmission device for nursing beds

Abstract

The invention relates to a labor-saving transmission device for nursing beds, which comprises a first power output shaft to drive a transmission mechanism, and then a first push-up rod and a second push-up rod are driven by the transmission mechanism, respectively. The first push-up rod can drive a back movable frame to form an inclined angle, and the second push-up rod can synchronously drive downward settlement of a leg movable frame. According to the invention, the transmission device formed by the lever operation principle is used in the nursing bed, so that the transmission device has a labor-saving characteristic and an operation convenience, and then can be used for patients to finish the act of defecating directly on the beds, so as to achieve an effect of self-care for patients.

Description

technical field [0001] The invention relates to a labor-saving transmission device for a nursing bed, especially a device that uses the principle of lever operation and has labor-saving characteristics. Background technique [0002] With the gradual aging of the population in Taiwan, China, many diseases of the elderly have also increased, and many people with mobility impairments, strokes, brain lesions, central nervous system damage, paralysis, or long-term bedridden people lack mobility and must lie in bed for a long time. In the nursing bed, the movement of the patient needs to be assisted by family members and nurses with greater strength, which also causes inconvenience to the family members, nurses and patients. The problem makes the patient feel that he has lost his dignity and puts a great psychological burden on the patient. [0003] Figure 1A and Figure 1B As shown, it is a kind of "automatic nursing bed" disclosed by CN101912332A, which includes: a bed body 1...

AI Technical Summary

Problems solved by technology

But check, most of the driving parts 131a, 133a used in the existing nursing beds are directly driven by pneumatic cylinders, but these driving parts 131a, 133a are arranged under the bed body 1, and push the back movable plate in a direct driving mode. 131 and the leg movable pole 133 are very strenuous, so the braking capacity should not be too small. In this way, not only power consumption, but also the driving part 133a is arranged at the bottom of the leg movable plate 133, so that the leg movable plate 133 can only go upward. lifts up and cannot sink down, therefore, Figure 1B In the shown usage pattern, when the patient uses the nursing hole 132a to excrete, the legs must be lifted up. In fact, this posture is not very appropriate and comfortable, and there is still room for improvement.
