Temporary fixing device for dialysis catheter

Technical Field

The utility model belongs to the technical field of medical equipment, and particularly relates to a temporary fixing device for a dialysis catheter.

Background

Hemodialysis is one of the renal replacement therapy modes for patients with acute and chronic renal failure. It is characterized by that it utilizes the in-vivo blood to drain into the outside of body, and utilizes a dialyzer formed from innumerable hollow fibers, and utilizes the electrolyte solution (dialysis liquor) whose concentration is similar to that of body to make mass exchange between the blood and inside and outside of one hollow fiber, and utilizes dispersion/convection to remove metabolic waste material in the body, retain electrolyte and acid-base balance, at the same time remove excessive water in the body, and the whole process of back-transfusion of purified blood is called hemodialysis, and the dialysis catheter is an implement necessary for hemodialysis.

The dialysis catheter is partly to be inserted into the right atrium, the other part is exposed to the outside for connecting an external blood delivery tube, the part of the catheter exposed to the outside is fixed on the skin of a human body through a kafu, the kafu is usually placed in a subcutaneous tunnel at a position which is 2 cm away from the skin outlet of the catheter, the kafu can be gradually wrapped by fibroblasts within one week to ten days after puncture, and the scar tissue and subcutaneous tissue near the kafu can be gradually and tightly combined with the peripheral side of the kafu along with the extension of time, so that the catheter position is fixed and the displacement is prevented, and the device for fixing the dialysis catheter by using the kafu can be referred to as the following patents: for example, chinese patent No. ZL202110553402.4 (publication No. CN113144378 a) discloses a medical catheter with a kafu (a), which mainly includes a catheter body, wherein a kafu is disposed on an outer surface of the catheter body, and an edge of the outer surface of the kafu is connected with the outer surface of the catheter body through a polymer film.

Here, a situation arises: since the optimal position of the outlet of the dialysis catheter is located at 1/3 of the right atrium to ensure sufficient blood flow, the outlet of the dialysis catheter does not reach the target position due to incorrect operation of an operator, incorrect fixation of the patient and the dialysis catheter in clinical use. It is also most important that after a certain period of use of the dialysis catheter, the blood vessel of the human body near the orifice of the dialysis catheter is stimulated by external stimulus for a long period of time, and a stenosis phenomenon starts to occur, so that a fiber sheath is formed on the dialysis catheter, and finally, the blood flow of the dialysis is reduced, and even the dialysis is difficult.

Therefore, it is a urgent need for a solution to the problem of providing a device for increasing the blood flow of dialysis through a dialysis catheter, which is convenient to operate and which allows a vascular stenosis to form a fibrous sheath.
