Description

A nursing bed facility with auxiliary turning function

technical field

The invention belongs to the technical field of medical facilities, and in particular relates to a nursing bed facility with an auxiliary turning function.

Background technique

Nursing beds refer to bed facilities that provide nursing functions for patients, meet the bed-ridden living habits of patients and meet the needs of adjuvant therapy, and are convenient for medical staff and their families to accompany them. There are more and more in modern medical environments and family scenes. Applications.

For bedridden patients, an important part of applying nursing activities is turning the patient over. Patients who lie down for a long time will generate local pressure on the body and the bed surface for a long time, and pressure sores or bedsores will occur after a long time. Therefore, whether it is in nursing clinics or at home, patients who have been lying down for a long time have to be turned over regularly/on time. In addition to turning over on time, massage the patient regularly, which will promote blood circulation and reduce the incidence of pressure ulcers. After each bowel movement, it must be cleaned up. Regularly cleaning the skin can effectively reduce the problem of bacterial infection. The aforementioned defecation activities and cleaning activities are usually based on turning the patient over. Patients who lie down for a long time can also cause hypostatic pneumonia, so in addition to massage and turning over, the patient should be buckled regularly to accelerate the discharge of the accumulation in the lungs.

It can be seen from the foregoing that the operation of turning the patient over is an important operation in the nursing process. The quality of the turning operation directly determines the nursing effect felt by the patient, and also greatly affects the convenience of the nursing staff in applying nursing activities. sex.

Some existing nursing beds already have a certain auxiliary turning function. The existing nursing beds with auxiliary turning function are usually arranged in the middle of the bed surface side by side with two bed boards that can tilt independently. The power of turning is driven by the pusher. Rod motor provided. When it is necessary to turn over, the controller can operate the flap on one side to tilt and raise, and the patient will turn over to the other side. If it is only half-turned, the bed will stop at a certain angle and the patient's body will be in a tilted state. This relieves pressure sores or bedsores caused by back pressure. If it is turned over completely, after the bed board is tilted to a certain angle, the nursing staff will catch the patient's body and slowly put it down, and finally the patient will lie on the bed, which is convenient for back cleaning, massage and back buckle, etc., until all nursing activities are applied. Then turn over and reset again.

The existing nursing bed with auxiliary turning function has the following problems: the patient's body is usually located in the approximate middle position of the bed on the nursing bed (that is, the midline of the back approximately coincides with the gap between the two bed boards), so that the aforementioned auxiliary turning mechanism acts At the same time, the patient's body will be clamped between the two bed boards, resulting in discomfort, and in severe cases, it will fail to turn over. In fact, in the nursing bed with the above structure, before the patient turns over, the nursing staff usually moves the patient to one side a certain distance to make the body deviate from the center of the bed, and then activate the bed board on the side to tilt the bed. Turn over assist. It is conceivable that when the patient turns over completely (that is, lying on the bed), the patient is turned from one side of the bed to the other, and the body is deviated from the center of the bed. Nursing activities usually require repositioning the patient to approximately the middle of the bed. Therefore, the existing nursing bed is accompanied by the repeated transfer operations (such as pushing and pulling, moving, etc.) of the patient to the patient when the patient is turned over. However, due to the poor ability of autonomous movement of such patients, the transfer operation can only be performed. Relying on nursing staff, which leads to excessive labor intensity of nursing staff, thereby affecting the nursing effect.

Therefore, it is necessary to optimize the design of the structure of the nursing bed, so that it has a more reasonable and humanized auxiliary turning function.
