Thrombolytic catheter fixing device

Technical Field

The utility model relates to a thrombolysis catheter fixing device in the medical technical field.

Background

Thrombosis is a common condition, which is a small mass of blood flow formed on the surface of a denuded or repaired site within a blood vessel of the cardiovascular system, consisting primarily of insoluble fibrin, deposited platelets, accumulated white blood cells and entrapped red blood cells. The formation of thrombus is a multifactorial process of interaction and mutual influence of a group of genetic and environmental factors, and the deterioration of the environment and the disordered living habits accelerate the formation of thrombus, so that the thrombus disease is younger and younger at present. Thus increasing the need for thrombus treatment.

To dissolve thrombus and open blood vessels, thrombolytic drugs are often delivered to the diseased area, often requiring an interventional procedure. The interventional operation is a method of introducing special catheters, guide wires and other precise instruments into a human body through a vascular sheath under the guidance of medical imaging equipment to diagnose and locally treat internal pathological conditions. The vascular sheath consists of a dilator, a sheath tube, a side arm connecting tube, a hemostatic valve and a joint, and is designed to be inserted into a vascular system through percutaneous puncture, and a catheter, a balloon catheter or a stent is introduced to perform interventional diagnosis or therapeutic operation. Aiming at dissolving thrombus, the adopted catheter is called a thrombolysis catheter, the length of the catheter can reach 50-80 cm, and thrombolysis medicines are continuously pumped after the thrombolysis catheter is inserted into a thrombus part, and the operation is also called thrombolysis.

However, the process of thrombolysis is long, the remaining time of the thrombolysis catheter can be as long as one day or several days, the fixation and protection of the thrombolysis catheter are very important, and the human body can be injured if the conditions of tube detachment, displacement or tube folding and the like occur. Currently, the commonly used fixation methods include fixing the skin and the vascular sheath with a needle and thread, fixing with an elastic adhesive tape, or fixing with a transparent patch. However, the use of needle and thread fixation requires suturing, which is cumbersome to operate and may not be compatible with the patient; when the elastic adhesive tape or the transparent adhesive plaster is used for fixation, the problem of infirm fixation and even reverse folding of the thrombolytic catheter is easily caused.
