Device for preventing displacement of deep vein catheter during blood purification

Abstract

The invention discloses a device for preventing the displacement of a deep vein catheter during blood purification. The device for preventing the displacement of the deep vein catheter during blood purification comprises an application main body. A main seat and a magnetic sheet are fixedly connected into the application main body in an embedded mode, wherein the main seat and the magnetic sheet are arranged alternately. A magnetic body is connected into the main seat in an inserting mode, an aluminum ring and a magnetic conductive plate are separately and fixedly connected into the main seatand located on the upper part and the lower part of the magnetic body, the top of the aluminum ring is fixedly connected with an electric heating sheet, the top of the electric heating sheet is fixedly connected with a thermochromic material, the outer side of the magnetic body is fixedly connected with a magnetic conductive sheet I, and the outer side of a magnetic sheet is fixedly connected witha magnetic conductive sheet II corresponding to the magnetic conductive sheet I. When the application is loose, the application main body is bent, the magnetic conductive sheet I is in contact with the magnetic conductive sheet II, the magnetic conductive plate is magnetized by the magnetic sheet, the magnetic body is repelled upwards, an electrical conductive sheet is in contact with the electric heating sheet, the electric heating sheet is electrified to give heat, a patient feels heat flow and then knows that the application is loose, the thermochromic material is discolored by heat, medical staff can directly determine whether the application is loose or not at a distance, and double protection is achieved.

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...
