Description

Block Array Care Bed

The invention relates to the technical field of mechanism design of care beds, in particular to a square array care bed.

As the population of Taiwan gradually ages, many elderly people with limited mobility often stay in bed; in addition, vegetative or paralyzed patients caused by accidents or car accidents also lie on the bed for a long time. In order to avoid decubitus ulcers and muscle atrophy caused by lying down for a long time, at least two medical staff or family members must turn over and pat the back of the patient regularly to promote blood circulation. However, the current shortage of medical staff in Taiwan, and the fact that most of the general hospital beds do not have the function of assisting the turning of the bed with an electric mechanism, which may cause the medical staff to exhaust their physical strength and affect other patients in urgent need of care.

In order to improve the aforementioned problems, the new patent number: M315090 discloses a "multifunctional hospital bed with rollover function". In the creation of the new patent number: M315090, it mainly uses the action of a first set of link mechanisms and a second set of link mechanisms to make the bed achieve the effect of backing up, raising legs and turning left and right; however, in order to accommodate And the hidden link mechanism, the bed frame of the carrying bed must be designed to be wider than the bed frame of the general bed, which may result in that the multifunctional bed cannot be placed in a general ward with a small space. On the other hand, in the process of assisting the patient to turn over, due to the excessive movement of the link mechanism, it may happen that the patient suddenly turns out of bed due to the excessive turning angle.

Therefore, in view of the fact that the conventional multifunctional hospital bed with rollover function still has many defects, the inventor of this case tried his best to research and invent, and finally developed a block array care bed of the present invention.
