A device for preventing displacement of deep vein catheter during blood purification

Abstract

The invention discloses a device for preventing displacement of a deep vein catheter during blood purification, which comprises an applicator main body. The inner part of the applicator main body is fixedly embedded with staggered main seats and magnetic sheets, and the inner part of the main seat is movably inserted with For the magnet, the interior of the main seat and above and below the magnet are respectively fixedly connected with an aluminum ring and a magnetic guide plate, the top of the aluminum ring is fixedly connected with a heating plate, the top of the heating plate is fixedly connected with a thermochromic material, and the outside of the magnet is fixed A magnetically conductive sheet 1 is connected, and a magnetically conductive sheet 2 corresponding to the magnetically conductive sheet 1 is fixedly connected to the outside of the magnetic sheet. When the application is loose, the main body of the application bends, the first magnetic conductive sheet contacts the second magnetic conductive sheet, the magnetic conductive sheet is magnetized by the magnetic sheet, and the magnet is repelled, the conductive sheet contacts the electric heating sheet, and the electric heating sheet heats up, and the patient feels it himself Once you see the heat flow, you will know that the application is loose, and the thermochromic material will change color when heated. Medical staff can directly judge whether the application is loose from a distance, which has double protection.

Description

technical field [0001] The invention belongs to the technical field of venous catheterization equipment, in particular to a device for preventing displacement of deep vein catheterization during blood purification. Background technique [0002] Blood purification, also known as dialysis, is to draw the patient's blood out of the body, and remove some pathogenic substances in it through a purification device, so as to purify the blood and treat diseases. Among them, the deep vein catheter is directly placed in the deep vein Puncture, insert the corresponding catheter through the vein, and place the catheter into a relatively deep vein to achieve the purpose of treatment and detection. It is often used in major rescue and surgery procedures. [0003] In order to prevent the deep vein catheter from falling off, the catheter should be sewn on the skin after puncture, and then the exposed part should be fixed with a sterile applicator. When performing various treatments and nursi...
