Description

A multifunctional medical chair

technical field

The utility model relates to a medical chair, in particular to a multifunctional chair for elderly care, which belongs to the field of medical equipment.

Background technique

Falls are accidents that are prone to occur in the elderly, and related literature reports that the occurrence of falls, the resulting injuries, and the economic burden are increasing with age. Falls are also the most common adverse events in hospitals, accounting for 38% of hospital adverse events. According to foreign reports, the incidence of falls in hospitalized patients is 2.3-7.0‰ per day, and the incidence of falls in international hospitals is 0.2%. Studies have shown that 39%-44% of falls are caused by environmental factors. According to relevant literature reports, falls caused by environmental factors in chairs Falls accounted for 35.86%. Falls resulted in an injury rate of 42 per cent and serious injuries in 8 per cent. On the one hand, falls will directly affect the physical and mental health and quality of life of patients, and at the same time, the occurrence of falls in hospitals may also cause medical care disputes. In severe cases, falling may lead to the accidental death of the patient, and cause serious incidents in which the family members and the hospital directly confront each other.

According to the report of the World Health Organization (WHO), about 400,000 people die from falls every year in the world, and there are 130 million elderly people in my country. At least 20 million people have 25 million falls every year, and the potential life loss rate is nearly 6 million years. Direct medical expenses In more than 5 billion yuan.

Even the most common accidental fall will seriously affect the physical and mental health of the patient and delay the recovery speed of the patient without causing other injuries to the patient, increasing the pain and burden of the patient and his family, hospitalization costs, and causing medical expenses. Ongoing tension in the patient relationship. Therefore, falls have attracted widespread attention in the medical field, and at the same time, the market for falls has been continuously developed.

At present, various fall prevention measures are adopted by different hospitals, including various products such as adjustable seats, night auxiliary lighting, fluorescent guide signs, and furniture without sharp angles. or position plays a role in fall prevention. However, for the situation that the elderly need to be cared for individually, medical staff need to face a large number of different patients, and are busy with work, so it is difficult to effectively take care of each patient at the same time. At this time, a convenient seat is needed to help medical staff improve the level of care for elderly patients. Extensive improvement and application of seats in the prior art, including the following functions: the height-adjustable swivel seat of the chair, the backrest angle can be adjusted at will, the multifunctional chair with storage function, and the warning function of the back of the chair with fluorescent function sex seat and more. But above-mentioned chair all exists the problem that function is comparatively single, can not satisfy various demands. In particular, elderly care centers need to take into account more aspects of care for severely disabled patients.

For example, Chinese patent CN 101695419A discloses a multifunctional chair that can store items safely and can be used as a bed. The utility model is characterized in that the chair seat is a cabinet, and the upper cover of the cabinet is a chair seat board; the chair seat and the chair back form a foldable connection. An anti-theft device is provided on the cabinet. The present invention has a foldable mechanism, so that the present invention can be used not only as an ordinary chair, but also as a single bed; a cabinet is formed under the seat of the chair, so that the chair can not only sit on people, but also store items, which greatly saves space. This chair can conveniently store items and be used as a makeshift bed when it is folded down, but it is not suitable for patients who need to be nursed alone.

Another example is that Chinese patent CN 104414247A discloses a multifunctional chair including a seat surface, a backboard, chair legs, a rotating shaft, a telescopic rod, a pin shaft, and a chair back. The cooperation of the shafts can support the backboard to a horizontal position, and the chair back can be stretched outwards by means of telescopic rods. If you need to support the backboard, first you need to stretch the back of the chair with the telescopic rod, then just rotate the backboard around the rotation axis, and then use the cooperation of the telescopic rod and the pin to support the backboard to a horizontal position, and you are done. The purpose of supporting the backboard is that the backboard can be put down after use, and the back of the chair can be retracted by the telescopic rod to be used as an ordinary chair. This new type of chair mainly can be adjusted and deformed to realize the rotation of the backboard around the axis, and it can be used in the conversion between the chair and the temporary cot, but it is not suitable for the nursing situation in the hospital.
