Vascular access flow detector

Abstract

The invention discloses a vascular access flow detector. The device comprises a blood flow detector body, an anti-rotation block, a compressed air bag and a bandage. An anti-rotation block is arranged on one side of the blood flow detector body; sliding frames are connected to the two sides of the anti-rotation block, and a pair of compressed air bags is arranged on the anti-rotation block; a pair of clamping elastic sheets is arranged in the compression air bag; and a bandage is arranged on the anti-rotation block. The binding belts are connected with magic stickers, fixed clamping blocks are connected into the sliding frames, sliding deviation preventing grooves matched with the fixed clamping blocks are formed in the sliding frames, and a penetrating shaft is connected between the pair of sliding frames. By arranging corresponding mechanisms on the vascular access flow detector, the stability of the injector is effectively improved, and the possibility that the injector shakes and falls off is greatly reduced; therefore, the precision of the vascular access flow detector is improved, and the credibility of measured data is also greatly improved. Meanwhile, secondary injury to a user and waste of medical resources are avoided.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a blood vessel access flow detector. Background technique [0002] Hemodialysis is one of the methods of renal replacement therapy for patients with acute and chronic renal failure. It can drain the blood from the patient's land to the outside of the body, exchange substances, remove metabolic waste in the body, maintain electrolyte and acid-base balance, and maintain proper blood vessel Access is a prerequisite for hemodialysis and can be divided into temporary vascular access and permanent vascular access. [0003] At present, it is generally accepted and common practice in most hospitals in China that nurses evaluate the patency of vascular access by manual pumping and pushing with the help of syringes, and assess whether the blood flow can meet the requirements for hemodialysis or filtration through personal experience. When the blood flow can be performed on th...
