Description

A pressure ulcer prevention device for bedridden patients in neurology department

technical field

The invention belongs to the technical field of medical devices and relates to a pressure ulcer prevention device, in particular to a pressure ulcer prevention device for bedridden patients in neurology.

Background technique

There are many bedridden patients in the neurology department, and there are many patients with incontinence. Due to long-term bed rest, the blood circulation is blocked, the muscles are atrophied, the limbs of the patients are stiff, and the humid environment is likely to cause pressure sores on the skin of the patients; once the pressure sores form It is more difficult to cure, which not only brings greater pain to the patient and affects the recovery of the patient, but also brings a greater workload to the medical staff.

After data analysis and comparison of a large number of patients, pressure ulcers generally occur on the buttocks and shoulders of the human body. When caring for bedridden patients, the purpose is to prevent pressure ulcers. Medical staff or patients' family members need to frequently roll over and massage the patient. Rehabilitation training to promote the recovery of patients; however, frequent turning over, massage, and rehabilitation training not only increase the nursing intensity of medical staff or the patient's family members, but also cause some discomfort and conflict to the patient if the operation is too frequent. Psychologically, it affects the recovery speed of patients.

At present, in the nursing process of bedridden patients, although the medical staff can use the bed to assist the patient to turn over, most of the existing beds do not have the massage function; therefore, when massaging the patient, the patient needs to be turned over, especially for the patient When the back is massaged; and when the patient is massaged, it is still necessary to massage the patient manually, which not only brings greater nursing intensity to the medical staff or the patient's family, but also massages the patient in the state of turning over, which brings great benefits to the patient.
