Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a pneumatically restrained intelligent turning and nursing mattress. Background Technology

[0002] A turning mattress is a medical assistive device used by medical staff to help reposition long-term bedridden patients. Patients who are bedridden for extended periods are highly susceptible to pressure sores, also known as bedsores or pressure ulcers. These are skin and tissue injuries localized to the body's position, caused by prolonged pressure leading to insufficient blood supply, resulting in skin damage, ulceration, and even necrosis. Pressure sores commonly occur in patients who are bedridden for extended periods, especially those with limited mobility and restricted local nerve and blood supply.

[0003] Currently, most turning operations for long-term bedridden patients are performed manually by two medical staff. First, one medical staff member places one hand under the patient's neck and shoulder and the other hand under the patient's waist, while the other medical staff member places one hand under the patient's waist and the other hand under the patient's knee. The two medical staff members bend over simultaneously and lift the patient, gently pushing the patient to the other side. Finally, a soft pillow is placed on the patient's back. This turning operation not only increases the labor intensity of medical staff, but also easily exposes the patient's skin to friction and shearing forces, causing skin damage and significant discomfort to the patient.

[0004] In addition, a small number of patients use existing turning mattresses to assist in the process. For example, patent application number 2018201765146, entitled "A Pneumatic Turning Mattress," includes a main mattress, a left airbag located on the left side of the main mattress, a right airbag located on the right side of the main mattress, and an inflation component for inflating the left and right airbags to turn the main mattress to the left or right. The main mattress is formed of 3D cotton and multiple main carbon fiber rods. A traction layer is connected to the bottom of the main mattress. When the patient turns over, medical staff control the inflation of the corresponding airbags to apply force to the main mattress to the corresponding side. Although this type of pneumatic turning mattress can solve the problem of assisting patients in turning over, it is difficult to avoid the formation of pressure sores, and it is difficult to adjust the pressure on areas with greater pressure. It cannot provide effective care for patients who are bedridden for a long time, and it brings great inconvenience to the care of patients who are bedridden for a long time. Utility Model Content
