Description

Central venous catheter tunnel flusher with polyester sleeve

Technical Field

The utility model relates to a medical treatment technical field particularly, is a take dacron cover central venous catheter tunnel flusher.

Background

In recent years, the incidence of end-stage renal disease patients is continuously increasing, and the clinical symptoms of uremia are rapidly relieved by the maintenance hemodialysis, so that the method is an important mode for treating the end-stage renal disease. In 2020, approximately 70 ten thousand patients with hemodialysis are registered according to conservative statistics. Vascular access is an indispensable prerequisite for hemodialysis treatment, called the "life line" of hemodialysis patients; however, some patients cannot establish self arteriovenous internal fistula due to various reasons, and the catheter with the dacron sleeve becomes a second-place access type. The central venous catheter with the dacron sleeve is simple to operate, convenient to use and long in retention time, and is one of effective dialysis channels for patients with maintenance hemodialysis. However, catheter-related infections have been a major problem with central venous catheter use. Catheter-related infections occur at more than ten times the rate of autologous arteriovenous internal fistulas. Increasing the risk of catheter-related infections, mortality, and hospitalization costs. The catheter nursing work is well done, and the catheter nursing work is particularly important for preventing catheter infection and catheter dysfunction. The infection of the catheter with the dacron sleeve can be divided into: (1) catheter bacterial colonization, (2) catheter outlet infection, (3) catheter tunneling infection, (4) catheter-associated bacteremia, i.e., CRBSIs, (5) catheter-associated migratory infection, including bacterial infectious endocarditis, suppurative arthritis, osteomyelitis, and the like. The catheter tunnel infection is the primary reason for catheter removal, and the success rate of catheter infection rescue is only 25-30%.

Catheter tunneling infection is infection in a catheter subcutaneous tunnel that is more than 2cm from the exit. Once the catheter infected by the proximal end of the dacron sleeve is infected by a tunnel, the whole body is mainly treated by using antibiotics clinically at present, but the patient still cannot be controlled after active infection resistance for 72 hours needs to be pulled out, only the surface skin of the tunnel opening can be disinfected locally, the focus cannot be directly reached, the treatment effect on the catheter tunnel infection is influenced, and the catheter pulling probability of the patient is increased.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem in the prior art, for example, the utility model discloses a take dacron cover central venous catheter tunnel flusher, include: the syringe comprises a syringe body, a connecting pipe, a hose needle, a handle part and an administration hole;

the syringe is characterized in that a connecting pipe is arranged on the syringe body, a hose needle head is arranged at the top of the connecting pipe, a handle part is arranged at the joint of the hose needle head and the connecting pipe, and a plurality of dosing holes are symmetrically formed in the front side and the rear side of the outer circumference of the hose needle head.

Preferably, the hose needle length is between 4-6 cm.

Preferably, the hose needle diameter is 1mm.

Preferably, the syringe body is provided with a scale.

Preferably, the hose needle is made of medical grade PVC.

The utility model provides a take dacron cover central venous catheter tunnel flusher possesses following beneficial effect: the device can disinfect and resist inflammation of the part of the tunnel infection focus, combines whole-body anti-infection treatment, greatly improves the curative effect, shortens the treatment time and reduces the tube drawing rate.
