Description

Lifting and transferring device for paralyzed patients

technical field

The invention relates to a transfer device for a patient, more specifically, to a lifting transfer device for a paralyzed patient.

Background technique

Population aging has become a major social problem in the world. Most of the elderly people suffer from chronic diseases such as high blood pressure and cardiovascular and cerebrovascular diseases. Sensitive, weakened resistance to disease, and long-term bed rest will cause decubitus and other complications such as pneumonia, constipation, and urinary incontinence. According to the data provided by the Office of the National Committee on Aging, by the end of 2014, my country's disabled and semi-disabled elderly population accounted for about 40 million, and with the spread of labor shortage, taking care of these patients has become a heavy burden for families and society. Nursing such patients is labor-intensive and expensive, and has become a major social problem.

In the nursing process of paralyzed patients, taking care of their daily life is what the nursing staff and family members need to do. For the nursing staff and family members, the transfer of patients is a very troublesome and labor-intensive task. At present, it mainly relies on manpower Carrying, this has just increased the labor intensity of hospital nurse and family member, and also there are some unsafe factors in the manual handling process. Among the existing care products for paralyzed patients, there is no shortage of transfer devices for paralyzed patients. However, most of these devices have a single action and can only lift the patient. Poor; there are also some transfer devices with complex structures and poor practicability.
