Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a patient transfer machine. Background Art

[0002] The sling-clamp type transfer machine can realize the safe transfer of paralyzed patients, leg and foot injured patients or the elderly between beds, seats, etc., solve the movement of people with limited mobility such as the elderly, disabled and bedridden patients and the positioning control of patients' body positions, reduce the workload of nursing staff, improve nursing efficiency and reduce nursing risks.

[0003] After searching, Chinese patent announcement number CN211705129U discloses a sling clamping type transfer machine, which includes a machine body, a hydraulic cylinder and a hanger mechanism. Two hydraulic cylinders are installed on the front of the machine body, and the tops of the two hydraulic cylinders are fixedly connected to two vertical connecting rods. The hanger mechanism is fixedly connected to the two connecting rods. The hanger mechanism consists of a fixed block, a telescopic column, a pressure plate, a movable plate, a limit spring, a hanging plate and a hook. In the sling clamping type transfer machine, when the patient is hung on the hook using a hanging cloth, the arc-shaped protrusion at the bottom of the pressure plate is inserted into the slot at the top of the corresponding limit plate, and the telescopic column cannot drive the hanging plate to rotate, so that the lifted patient can only face one direction, ensuring that the lifted patient will not rotate, and avoiding the problem of unbalanced force when the hanger mechanism lifts the patient, causing the patient to rotate or swing continuously under the hanger mechanism, causing the patient to have adverse reactions such as dizziness and physical discomfort.

[0004] However, in the above technical solution, the telescopic column cannot drive the lifting plate to rotate only by inserting the arc-shaped protrusion at the bottom of the pressure plate into the slot at the top of the corresponding limit plate, so that the suspended patient can only face one direction, ensuring that the suspended patient will not rotate. However, each patient has a different height and weight, and the position of the hook is fixed. When the hook hooks the cloth to lift the patient, the spacing between the top hooks is too small, which may cause the patient's upper body and head to be easily squeezed. The squeezing of the cloth may easily lead to poor blood circulation and cause harm to the patient's body. Utility Model Content
