Description

Nursing bed facility with auxiliary turning-over function

Technical Field

The invention belongs to the technical field of medical facilities, and particularly relates to a nursing bed facility with a function of assisting in turning over.

Background

The nursing bed is a bed facility providing a nursing function for patients, meets the living habits of the patients lying in bed, is matched with the requirements of auxiliary treatment, is convenient for medical care personnel and family members to accompany, and has more and more applications in modern medical environments and family scenes.

For patients who are permanently confined to bed, an important aspect of applying a nursing activity is turning the patient over. The body and the bed surface of a patient who lies for a long time can generate local pressure for a long time, and pressure sores or bedsores can be generated after the patient lies for a long time. Therefore, patients who are long in time can turn over on time whether in clinic or at home. Besides turning over the body on time at ordinary times, the patient needs to be massaged at regular time, so that blood circulation is promoted, and the incidence rate of pressure sores is reduced. After each defecation, the patient needs to be cleaned, and the skin is cleaned regularly, so that the problem of bacterial infection can be effectively reduced, and the defecation activity and the cleaning activity are usually based on the turning-over operation of the patient. Patients who lie for a long time can also cause falling pneumonia, so the patients need to be buckled with the backs at regular time to accelerate the discharge of accumulated matters in the lungs besides massage and turning over.

From the foregoing, the operation of turning over the patient is an important operation content in the nursing process, and the quality of the turning-over operation directly determines the nursing effect felt by the patient, and greatly affects the convenience of nursing activities applied by the nursing staff.

Some existing nursing beds have a certain auxiliary turning-over function, two bed plates which can independently tilt and move are usually arranged in parallel in the middle of a bed surface of the existing nursing bed with the auxiliary turning-over function in structure, and power for turning over is provided by a push rod motor. When needs stand up, the board that turns over through controller operation one side verts and rises, then the patient just stands up to the opposite side, if only partly stand up then this bed board stops to be in the state of slope at certain angle messenger disease's health, can alleviate pressure sore or bedsore that back pressure leads to like this. If the patient turns over completely, the patient is caught by the nursing staff and slowly put down after the bed board is tilted to a certain angle, and finally the patient lies on the bed, so that the back is convenient to clean, massage, buckle the back and the like, and the patient turns over again in a reverse direction and resets after applying all nursing activities.

The prior nursing bed with the function of assisting in turning over has the following problems: when a patient is in a nursing bed, the body of the patient is usually located at the approximate middle position of the bed (namely, the midline of the back approximately coincides with the gap between the two bed boards), so that when the auxiliary turnover mechanism is actuated, the body of the patient is clamped between the two bed boards, uncomfortable feeling is generated, and turnover failure is caused in serious cases. In fact, before the patient turns over, the nursing bed with the above structure usually moves the patient to one side for a certain distance to make the body deviate from the center of the bed, and then starts the bed plate on the side to turn over. It is envisaged that when the patient is turning over completely (i.e. lying on the bed), the patient is turned over from one bed plate to the other, the body is off centre with the bed, and it is also generally necessary to reposition the patient to approximately the centre of the bed in order to perform subsequent nursing activities. Therefore, when the patient is turned over, the existing nursing bed is accompanied with repeated transfer operations (such as pushing, pulling, moving and the like) of the nursing staff to the patient, and the patient only depends on the nursing staff due to poor autonomous movement capability, which causes overlarge labor intensity of the nursing staff and further influences the nursing effect.

Therefore, the structure of the nursing bed needs to be optimally designed, so that the nursing bed has a more reasonable and more humanized turnover assisting function.
