Description

Technical Field

[0001] This utility model relates to the field of pressure ulcer prevention for long-term bedridden patients, specifically to a portable side-lying device for preventing pressure ulcers in the sacrococcygeal region of long-term bedridden orthopedic patients. Background Technology

[0002] Pressure ulcers are a common complication in fracture patients. Prolonged bed rest and poor blood circulation due to pressure on the skin can easily lead to pressure ulcers. In lower limb fracture patients, pressure ulcers commonly occur at bony prominences such as the sacrum, heel, and hip. While lateral repositioning is an effective way to prevent pressure ulcers, bedridden fracture patients cannot exert force independently, and regular lateral repositioning increases the workload for caregivers. Furthermore, patients' reluctance to frequently change position due to pain leads to prolonged pressure in the same position, resulting in pressure ulcers. In addition, pain and positional restrictions cause irritation to the sacrum and coccyx during urination and defecation, also contributing to pressure ulcer formation in orthopedic patients who are bedridden for extended periods. Pressure ulcers not only cause significant pain but can also lead to serious infections.

[0003] Currently, existing devices for preventing pressure sores on the sacrococcygeal region in long-term bedridden patients only address the problem of prolonged skin pressure, but do not solve the problem of skin irritation caused by urine and feces, nor do they reduce the workload of nursing staff, causing many problems for both patients and nursing staff.
