Description

Double-cavity catheter fixing device

Technical Field

The utility model relates to a catheter fixing device, in particular to a double-cavity catheter fixing device, and belongs to the field of medical treatment.

Background

At present, CRRT is widely applied to severe patients and becomes the third treatment means after mechanical ventilation and nutrition support, and the CRRT patient CLABSI incidence rate has more documents but is not reported in different ways at home and abroad. Once the patient has CIABSI, the usage rate of the antibacterial drug is increased, the hospitalization time of the patient is prolonged, and the hospitalization cost is increased. In recent years, how to adopt effective measures to reduce the CLABSI incidence rate of patients and improve the CRRT treatment success rate becomes the focus of attention of medical care personnel.

After the catheterization and after CRRT, the puncture position of the catheter is covered by sterile gauze or sterile transparent dressing, the sterile gauze is replaced at least once every 2 days, the sterile transparent dressing is replaced at least once every 5-7 days, the dressing is replaced in time when being moist, loose or polluted, a temporarily unused venous access is sealed for 1 time in 24h, blood return is firstly sucked before flushing, the previously injected tube sealing liquid is extracted, whether thrombus is formed in the tube is observed, the deep venous catheter adopts a pulse type flushing tube and positive pressure tube sealing technology, the requirements on the extension part and the street remaining part of the catheter are not unified, retrograde infection caused by the pollution of the catheter after the catheter is one of important factors causing the relevant blood stream infection of the catheter, skin bacteria around the puncture position easily move along the outer wall of the catheter, and the surface of the catheter is adhered by fibrin and other blood coagulation factors to form a biomembrane or a sheath, causing bacteria to adhere or colonize the catheter tip, causing infection. For long term catheterization, bacteria may enter the circulatory blood flow from the catheter hub along the inner wall of the catheter, eventually resulting in CLABSI.

The femoral vein catheterization is a common catheterization part of CRRT due to convenient operation and small risk, but the lower limb movement of a patient often causes the catheter to deform, and the dressing is difficult to be stably fixed; meanwhile, the femoral vein is located in the groin and adjacent to the perineum, is easily polluted by excrement and is not easy to keep clean. If the excrement and urine are not properly treated, the skin is not emphasized to be cleaned, the excrement, urine and dirt at the groin of a patient can be easily polluted, and the infection at the outlet of the catheter and the infection of the catheter are easily caused. The probability of CLABSI is increased due to sweating of the patient, neck movement, passing of tracheotomy laces, oral liquid pollution of dressing and the like.

At present, the clinical blood filtering catheter fixing has no unified standard, the connector is wrapped by gauze, the adhesive plaster is slightly fixed, a unified label does not exist for indicating the replacement time, the gauze is independently used as dressing, the fixing is not easy and stable, and the catheter and the street are more easily exposed to the air environment to cause pollution.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: it is an object of the present invention to provide a double lumen catheter securement device that reduces the incidence of catheter-related bloodstream infections, is easy to secure, and is easy to replace.

The technical scheme is as follows: the double-cavity catheter fixing device comprises two catheter kits and a dressing, wherein the two catheter kits are adhered to the dressing side by side.

The catheter assembly is coated with a silver ion antimicrobial agent on the inner surface. Protecting the catheter from contamination.

One side of the auxiliary material is coated with viscose. The transparent film is torn on the inner layer of the dressing and then the adhesive is applied, and the signature part on the outer layer is made of waterproof and anti-coating paper. When in use, the side coated with the viscose is pasted on the patient body to play a role in fixation.

Has the advantages that: compared with the prior art, the utility model has the following remarkable advantages: the aseptic design protects the tail end of the catheter and prevents pollution, and the inner layer of silver ion antibacterial dressing reduces the occurrence of blood stream infection related to the catheter; the dressing is easy to fix and not easy to fall off, so that a patient feels comfortable; one-step operation is realized, the tedious work is reduced, the dressing change time is saved, and the workload is reduced.

fig. 2 is a front view of the fixing device of the present invention.

Detailed Description

The technical scheme of the utility model is further explained by combining the attached drawings.

As shown in fig. 1, the double-cavity catheter fixing device comprises two catheter kits 1 and a dressing 2, wherein the two catheter kits 1 are adhered to the dressing 2 side by side. The inner surface of the catheter assembly 1 is coated with a silver ion antimicrobial agent. The dressing 2 is coated with adhesive 3 on one side. The dressing 2 is made of fiber non-woven fabric. The material of the conduit sleeve 1 is fiber non-woven fabric. The inner layer of the dressing 2 is torn off, and the hatched part is the adhesive 3.

The use method of the double-cavity catheter fixing device comprises the following steps: inserting two catheters into two catheter kits 1 respectively, adhering a dressing 2 on the surface of the skin of a patient by using an adhesive 3, and writing a change time and a signature on a signature part; and when the fixing device needs to be replaced, the fixing device is taken down and replaced by a new fixing device.

As shown in figure 2, the outer layer of the dressing 2 of the utility model is provided with a signature part, and the signature part is made of waterproof and anti-coating paper.
