Description

Applicator for fixing central venous catheter

Technical field:

The utility model relates to the technical field of medical equipment, in particular to an applicator for fixing a central venous catheter.

Background technique:

Indwelling central venous catheter is an important measure for rescue of critically ill patients, hemodynamic monitoring, and infusion of various drugs and nutrition. disease cannot be ignored. Central venous catheterization is an invasive treatment with some complications and risks such as catheter dislodgement, infection, subcutaneous hematoma, etc. Proper and effective fixation and nursing can avoid or reduce the complications of indwelling central venous catheters. Convenient and firm catheter fixation methods are related to the smooth implementation of various treatment items and are the guarantee for improving the quality of care. Seeking effective, safe, and immobilization methods that can relieve patients' pain has always been an urgent problem to be solved in the field of intensive care.

The 2011 guidelines for the prevention and control of bloodstream-associated infections from the US Centers for Disease Control recommend the use of suture-free fixation devices to reduce infection rates. Schears Gregory J's research shows that an effective suture-free method can reduce the total treatment cost and reduce re-placement of the tube, but the suture fixation technique needs to penetrate the skin with needles, which is easy to cause skin damage and destroy the integrity of the skin barrier, so it is relatively easy Infection, especially for patients with hypoproteinemia and edema, the suture needle holes are more difficult to heal, which increases the chance of infection. Suture-free is worthy of clinical promotion and application. However, the special materials for suture-free are expensive, and promotion is still difficult. At present, in order to ensure the effective fixation of catheters in domestic clinical practice, most critically ill patients still use traditional suture fixation. Although the deep venous line can be effectively fixed to prevent accidental slippage, the suture fixation can easily cause skin damage, destroy the integrity of the skin barrier, increase the chance of infection, and reduce the comfort of the patient. Bacterial application directly fixes the deep venous catheter. Complications related to this method, such as catheter displacement, slippage, and catheter-related bloodstream infection, are relatively common.

Utility model content:

The purpose of this utility model is to overcome the deficiencies of the prior art, and provide a kind of applicator for fixing the central venous catheter, which adheres the insertion point of the built-in tube into the skin, that is, the puncture point and the surrounding skin through the medical transparent film, effectively It greatly reduces the chance of skin infection and has a continuous protective effect, so it has a positive effect on reducing related infections. At the same time, its transparent adhesive tape can firmly fix the connecting hose and improve the comfort of fixing.

The scheme that the utility model solves described technical problem is:

An applicator for fixing a central venous catheter, including a central venous catheter. The central venous catheter includes a built-in tube, a fixing part, a connecting hose and a connector. The built-in tube is inserted into the human skin and inserted into a vein, and the medical transparent film is adhered to the On human skin, the insertion point and fixed part of the built-in tube are between the medical transparent film and the skin, the connecting hose is bent and placed above the medical transparent film, the transparent adhesive tape is pasted on the medical transparent film, and the connecting hose is in the medical transparent film. Between the film and the transparent tape.

Furthermore, the insertion point of the built-in tube into the skin is below the center of the medical transparent film.

Further speaking, one side of the transparent adhesive plaster has three strip-shaped parts, and the transparent adhesive plaster is an E-shaped block.

Furthermore, there is a through hole on the opposite side of the three strip-shaped parts of the transparent adhesive tape, and the fixing fins on the fixing part are located under the through holes.

Furthermore, the connecting head is between the medical transparent film and the transparent adhesive plaster.

The outstanding effect of the present utility model is:

Compared with the existing technology, it adheres the insertion point of the built-in tube into the skin, that is, the puncture point, and the surrounding skin through a medical transparent film, which effectively reduces the chance of skin infection and has a continuous protective effect. It has a positive effect on reducing related infections. At the same time, its transparent adhesive tape can firmly fix the connecting hose and improve the comfort of fixing.
