Internal fistula detection device and application method thereof

Abstract

The invention discloses an internal fistula detection device. The internal fistula detection device comprises a detection body, a rubber round pipe, rigid pipes and audio players, wherein the front end of the rubber round pipe is fixedly connected with the detection body; bifurcating pipes are arranged at tail ends of the rubber round pipe, and each rigid pipe is in sleeving connection to the branch pipe of the corresponding bifurcating pipe; and the tail ends of each rigid pipe are connected with the audio players. According to the internal fistula detection device disclosed by the invention,the size of internal fistula blood flow sound of a patient is detected by the audio players, and medical personnel can intuitively know the unobstructed properties of internal fistula in artery and vein of the patient through the decibel size of blood flow sound on a display, and further judge whether the patient needs to further detect the situation of the internal fistula; or the patient at home can intuitively know the unobstructed property situation of internal fistula in artery and vein of the patient through the decibel size of blood flow sound on the display and decide whether to needto go to hospital for further examination.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an internal fistula detection device and a use method thereof. Background technique [0002] Hemodialysis is currently one of the main methods of renal replacement therapy, and good vascular access is the "lifeline" for hemodialysis patients. Unobstructed vascular access is an important guarantee for patients with end-stage renal disease to achieve long-term hemodialysis. However, during use, fistula occlusion is a common complication, and even the main cause of death in maintenance hemodialysis patients. Until now, autogenous arteriovenous fistula is still the most ideal vascular access for permanent vascular access in maintenance hemodialysis patients. With the prolongation of dialysis survival and the aging of patients, as many as 30% of these patients need to be hospitalized due to hemodialysis failure due to hemodialysis access, among which arteriovenou...

AI Technical Summary

Problems solved by technology

Before hemodialysis or arteriovenous fistula care, uremia patients usually need to rely on medical staff to detect and judge the patency of the patient's arteriovenous fistula, and to see a doctor in time if there is stenosis or occlusion of the arteriovenous fistula; When the number of patients undergoing hemodialysis or arteriovenous fistula care is large, the existing ordinary stethoscope takes a long time to judge and has a low accuracy rate. Reversal of injury or even death, while ordinary stethoscopes have a small adaptability, patients at home cannot use ordinary stethoscopes to judge whether they need to come to the hospital for further examination, causing more troubles between doctors and patients
