Description

Intelligent lock for locking accompanying chair

Technical Field

The invention relates to the technical field of medical equipment, in particular to an intelligent lock for locking an accompanying chair.

Background

At present, because hospital beds in various cities are tense, families nursing patients are difficult to get vacant hospital beds to lie down for rest and sleep. In order to relieve the fatigue of caregivers and enable the caregivers to more comfortably lie and sleep while nursing patients, a dual-purpose chair for sitting and lying with a smaller floor space has been developed. The often be equipped with the chair of accompanying and attending to that supplies the patient of accompanying and attending to the person rest usefulness in the ward, for the convenience of accompanying and attending to the person and using, common chair of accompanying and attending to possesses folding function mostly, can expand into the bed through folding the chair of accompanying and attending to and supply the person of accompanying and attending to lie, realizes that a thing is dual-purpose. Through market research and communication with hospitals, it is found that ordinary accompanying chairs are difficult to popularize because many hospitals do not pay attention to the resting condition of caregivers and their financial budget division is not involved.

Most accompany and attend to the chair and do not have locking mechanical system, be in the daytime promptly, for the convenience family members watch patient and medical personnel inspection patient, its accompany and attend to the chair must be folded, and the family members who accompanies a bit can not fold the chair of accompanying and attending to, and with regard to a large amount of occupation space like this, inconvenient medical personnel and the family members who watches patient walk about, need carry out unified management. Simultaneously, after current chair of accompanying and attending to is folding, the both sides in the bottom the place ahead of its seat directly press on the supporting shoe that the inboard of two supports in the front portion of body frame is fixed with, when the people sits and moves about going on it, can make the seat control the small distance on two supporting shoes and remove, make the chair of accompanying and attending to damage not hard up easily.

In addition, the accompanying chair used in the hospital has no locking function, and the accompanying chair can be released by the family members of the patient only by slightly applying force. This causes inconvenience in the management of medical facilities in hospitals, and thus cannot achieve the purpose that the hospital requires family members to use the accompanying chair at a certain cost. And the accompanying chair can be used randomly, the daily loss of the accompanying chair is increased, and great loss is brought to hospitals.
