Description
Technical Field
The invention relates to the technical field of medical care, in particular to an intelligent feedback system for preventing pressure injury.
Background
Pressure injury is a common and frequent health problem in clinical care, and is often seen in critically ill patients, orthopedic injuries and elderly chronic patients. Once the patient suffers from pressure injury, the patient can suffer from pain, loss of function and infection, the hospitalization time is prolonged, and the fatality rate is increased. Therefore, in the clinical care process, the implementation of effective means for preventing the pressure injury has important significance.
The capillary pressure of human skin is 17mmHg, and the main reason for the occurrence of pressure injury is that when the pressure exceeding the capillary pressure boundary value is acted for a long time or the pressure and the shearing force are continuously acted on the human skin and subcutaneous tissues for a long time, the internal deformation, the strain and the stress of soft tissues are caused. The magnitude of the acting force and the acting time thereof are main factors causing the occurrence of the pressure injury, and when the acting force reaches a certain magnitude and time, the blood vessel perfusion and the lymphatic drainage are further hindered, so that the pressure injury occurs; meanwhile, the tissue tolerance (including age, nutrition, tissue bone morphology, health status, body system function, etc.) of an individual determines the threshold value of tissue damage of the individual. In the case of a patient who is unable to move and/or feels loss of sensation, these two factors work together to determine the time required for the individual to develop the stress injury, as well as the extent and severity of the injury. Therefore, according to the individual tolerance condition of the patient, the key point of preventing the pressure injury is to reduce the pressure/shearing force applied to the local part and adjust the local pressure time and turn over in time. Under different body positions, the bony protuberance of the pressed part bears higher pressure, for example, the pressure of the caudal sacral part and the heel part is increased in the lying position, and the pressure of the ischial tuberosities on two sides is increased in the sitting position. The pressure at the pressed part can be uniformly dispersed by using the body surface supporting device; the pressure points can be alternated by establishing the turnover plan, so that the action time of the local pressure is reduced, and the local long-time pressure is avoided.
At present, in the nursing process, nurses often adjust the placing positions of patients who cannot move and/or feel loss according to clinical experience, and the pressure value of local bony prominences of the patients in the placing positions cannot be quantified by the method, so that local effective decompression cannot be obtained necessarily; the main method for evaluating the turning effect and frequency is to check whether erythema exists on the skin of a pressed area during turning, and medical staff observe whether the body surface presents certain damage characteristics, such as continuous redness of local skin and no fading of the pressed skin, which is a sign of stage 1 pressure damage, and the existence of the continuous erythema indicates that the frequency of posture change needs to be increased. However, the internal strain and strain of the tissue adjacent to the carina is higher than the tissue stress and strain of the body surface, resulting in deep tissue damage before superficial tissue damage and before macroscopic damage. Deep tissue damage is indicated when there is a persistent deep red, maroon, purple change in local areas of the body surface, or when the epidermis is detached and exposes a dark wound bed or congestive blisters. The pressure injury in the 1 stage can be reversed by the decompression measure of more than 60%, but the deep tissue injury is observed, and the decompression adjustment is not favorable for recovery, so that the prevention effect cannot be achieved.
