Description

Supplementary turnover device of oscillating and stand up bed

Technical Field

The utility model relates to the field of medical instruments, in particular to a swing type auxiliary turnover device and a turnover bed.

Background

Medical institutions or health care institutions are important social service institutions and provide nursing for patients with injuries and old people, activities of which are limited by medical nursing dependence, wherein most of the patients need to lie in bed, and the life of the patients cannot be taken care of themselves. The patient can be easily suffered from pressure sores, bedsores and other diseases after lying on a sickbed for a long time, the diseases can aggravate the primary illness condition of the patient and increase the consumption of medical care resources, the death rate of the old patient is improved to be more than 4 times, and a plurality of researches prove that the assistance of the patient to turn over is an important measure for preventing and treating the pressure sores and is also a requirement for the patient to turn over and medical operation, so the patient lying in the sickbed is very important to nursing operation. However, the existing medical sickbed and nursing bed can only control the sickbed to enable a patient lying on the sickbed to sit up, and when the patient is subjected to an operation or a serious disease, the patient can not be helped to lie on the side or turn over when the patient needs to be wiped. At present, the nursing staff still assist the patient manually under the condition of helping the patient lie on the side or turn over, the operation labor intensity is high, the efficiency is low, and the additional injury to the patient is very easy to cause in the process. The bed-ridden patient turning-over assisting device is mainly of a structure similar to a grab bucket of an excavator, occupies a large space, affects other nursing and treatment on patients in a ward, is rough and robust in action in the using process, is hard in material, is easy to cause discomfort on the body and the mind of the patients, is high in manufacturing cost and high in using cost, and cannot be generally applied to conventional wards. In addition, some sickbeds with bed plate structures capable of being curled from the side direction are high in manufacturing cost and use cost, cannot be generally applied to conventional sickrooms, and are prone to causing mattress disorder in the use process and influencing nursing and treatment operations.
