Warning infusion patch

Abstract

The invention relates to a warning infusion patch and belongs to the technical field of medical supplies. The warning infusion patch comprises an infusion patch body and a warning unit, wherein the infusion patch body and the warning unit are of independent structures, the infusion patch body is provided with two inner electrodes, and two plug connection electrodes which can be in contact with the two inner electrodes are arranged in the warning unit. The infusion patch body further comprises an absorbing layer, two leads and an adhesive layer, wherein the absorbing layer comprises a first surface in contact with the leads and the inner electrodes and a second surface in contact with the adhesive layer, and the ends of the two leads are respectively connected to one of the two inner electrodes. The warning infusion patch can give a warning signal in time to remind a patient and a worker when attaching to the puncture part to cause exudation and errhysis, the safety of vein puncture treatment is improved, the warning unit can be repeatedly used, the infusion patch body has little difference with a common infusion patch, and large-scale popularization and application are promoted.

Description

technical field [0001] The invention relates to the technical field of medical supplies, and more specifically, the invention relates to an alarm transfusion patch. Background technique [0002] The transfusion patch is generally composed of a protective layer, an adhesive layer and a release paper. Remove the release paper during use, cover the protective layer directly above the puncture point, and fix it on the skin through the adhesive layer. Venipuncture is a common clinical operation, and there is a possibility of seepage and bleeding at the puncture site if the venipuncture channel is used for a long time for diagnosis and treatment activities. Among such patients, especially hemodialysis patients, because extracorporeal circulation needs to be established through a catheter or an arteriovenous fistula, once bleeding occurs at the puncture point or bleeding due to falling off of the puncture needle, serious consequences may even be life-threatening. In the prior art...

Problems solved by technology

Among such patients, especially hemodialysis patients, because extracorporeal circulation needs to be established through a catheter or an arteriovenous fistula, once bleeding occurs at the puncture point or bleeding due to the puncture needle falling off, it may lead to serious consequences, even life-threatening

In the prior art, various alarm devices have been developed in order to avoid bleeding at the puncture point or bleeding due to the falling off of the puncture needle, but they are generally controlled by clock counting, which has a complicated structure and relatively high cost. High, it is difficult to popularize and promote the application
