Blood vessel access monitoring device for hemodialysis

Abstract

The invention discloses a blood vessel access monitoring device for hemodialysis, wherein the device comprises a sound receiving module, a decibel measuring module, a frequency conversion module, a waveform conversion module, a data processing module, a display module, an alarm module, a photography module, a screen interception module and a terminal; the sound receiving module is connected with the decibel measuring module, the frequency conversion module and the waveform conversion module; the output end of the decibel measuring module, the output end of the frequency conversion module and the output end of the waveform conversion module are connected with the display module; the data processing module, the alarm module, the photography module and the screen interception module are respectively connected with the display module; the display module is connected with the terminal. By arrangement of the decibel measurement module, the frequency conversion module and the waveform conversion module, the quantification of blood vessel access monitoring is referred, and the device is more convenient and quick.

Description

technical field [0001] The invention relates to a medical monitoring device, in particular to a hemodialysis blood vessel access monitoring device. Background technique [0002] Hemodialysis is one of the alternative treatments for patients with chronic renal failure. Arteriovenous fistula is a common vascular access for hemodialysis treatment, and it is a prerequisite for maintaining extracorporeal circulation of blood. Arteriovenous fistula is to suture the artery near the wrist of the forearm and the adjacent vein, so that arterial blood flows in the anastomotic vein, forming an arteriovenous fistula. Arteriovenous fistula is the lifeline of hemodialysis patients, and maintaining long-term patency of arteriovenous fistula is very important for maintenance hemodialysis patients. It is recommended to perform blood vessel B-ultrasound evaluation when the arteriovenous fistula is first punctured, and the maturity of the arteriovenous fistula is the fundamental guarantee for...

Problems solved by technology

[0003] However, at present, judging whether the arteriovenous fistula is unobstructed is mainly judged by manual auscultation and the feeling of vascular tremors. There is no definite quantitative standard, which leads to inaccurate judgment and poor analysis efficiency. Currently there is no informationalized continuous tracking care
