Description

Human body lifting device for nursing bed

technical field

The invention belongs to the technical field of medical nursing appliances, and in particular relates to a human body lifting device for a nursing bed.

Background technique

Bedridden patients need to keep the bed dry and hygienic, so as to reduce the growth of bacteria and avoid complications such as bedsores. However, for patients who live in bed for a long time, eating, defecation and wounds will cause stains on the bed sheets. In order to keep the bed surface clean, the bed sheets need to be changed frequently. At present, in the nursing practice of home and medical institutions, most of them use manual replacement of bed sheets. Its disadvantage is that it is labor-intensive and requires high professional skills, which greatly increases the burden on nursing staff. In addition, when manually changing the sheets, the patient needs to be turned over on the bed, which will inevitably increase the physical burden of the weak patient; especially for patients with bone injuries and wounds, carelessness during the turning process may also lead to new injuries .

In view of the above reasons, people have also carried out a large amount of research and exploration and practice in this field, expecting to develop a nursing bed that is convenient for changing sheets. For example, the utility model patent "a hospital bed for convenient bed sheet replacement" with the authorized announcement number CN 203315211 U is composed of a steel bed board, headboard, footboard and bed legs, and side guards are provided on both sides of the bed to At the same time, it runs into the bed and is inserted flatly under the patient. Then, the motor and the transmission drive the T-shaped lifting screw rods at both ends of the bed board to slowly raise the two baffles at the same time, thereby raising the patient lying on the bed. And authorized announcement number is the utility model patent of CN203315237U " a kind of lifting device of human body on bed ", and it is on one side of the long side of the bed frame near the frame, and the shoulder, back, buttocks, and knees of the nursing person lying flat on the corresponding part of the bed One side is equipped with a guide tube supported by the bed body, and the inner hole of the guide tube is equipped with a push rod, and the upper end of the push rod can be fixed with the handle of the lifter. The mechanism works with the push rod, and the care receiver is lifted up by the lifting piece or fabric. The above scheme solves the problem of lifting the bedridden patient to a certain extent to replace the bed sheet, but it also has certain disadvantages, that is, there are certain operational difficulties in placing the side guard baffle or the lifting piece used to lift the patient under the patient's body. It is difficult and may cause discomfort to the patient, and its structure is also relatively complicated.
