Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a real-time blood seepage monitoring alarm and automatic compression device for dialysis. Background Art
[0002] Vascular access is the lifeline of patients undergoing maintenance hemodialysis (MHD). Good vascular access is the basic guarantee for patients with end-stage renal disease to successfully undergo MHD. Arteriovenous fistulas have become the preferred vascular access for MHD patients due to their advantages such as sufficient blood flow, easy puncture, high safety, low risk of infection, long service life, and easy monitoring and maintenance. Hemodialysis is usually performed 2 to 3 times a week, and fistulas require long-term repeated punctures. Clinically, the blood flow of mature arteriovenous fistulas is usually greater than 500 ml / min, which means that once bleeding occurs, a large amount of blood can be lost in a short period of time, and the bleeding rate can reach about 200 ml per minute. If the bleeding is not handled in time, it can cause local tissue swelling and necrosis, affecting the service life of the fistula. In severe cases, it may cause hemorrhagic shock or even endanger the patient's life, causing serious psychological burden and mental trauma.
[0003] In actual work, a nurse is usually responsible for about 5 dialysis patients and conducts rounds every 30-60 minutes, making it difficult to achieve real-time naked-eye observation of the puncture site; each dialysis treatment lasts about 4-5 hours. Although fixing the arm on the fistula side can prevent bleeding to a certain extent, it can easily cause discomfort to patients during dialysis; most patients are in a sleeping or semi-sleeping state during dialysis, especially elderly patients, those without family members, and those with decreased sensation or visual impairment, who often find it difficult to detect bleeding in time; only when severe bleeding causes changes in blood circulation pressure will the hemodialysis machine have a low venous pressure alarm and stop the blood pump. There is a time delay in this process, and it is impossible to achieve first-time monitoring of bleeding events.
[0004] Therefore, in view of the above problems, a real-time blood seepage monitoring alarm and automatic compression device for dialysis is proposed to solve the above problems. Utility Model Content
