Transparent hemostatic dressing and method for protecting central venous catheter

Abstract

The invention relates to a transparent hemostatic dressing and a method for protecting a central venous catheter, which improves the method for protecting the central venous catheters by using transparent dressings in the prior art. The hemostatic sponge is adhered to the transparent dressing used in clinical practice, and is used after sterilization, and the operation process requires only one nurse to operate safely. The method has the following characteristics: 1. the characteristics of the existing dressing are fully used: a film is soft, transparent, elastic, and breathable; 2. when the patient's platelets are low, even a small amount of errhysis is generated from a catheter puncture , the errhysis is immediately adsorbed by the hemostatic sponge, and the catheter is not easily slipped, 3. the hemostatic sponge also has a hemostatic function to promote hemostasis; 4. the puncture port is clean and dry, and is not easy to cause blood flow infection of the catheter; 5. one person can complete the operation, which saves human resources and improves the efficiency of catheter maintenance; 6. the transparent hemostatic dressing has a lower price than that of the conventional transparent dressing, and the patient has low economic burden and initial investment is small; and 8. the operation is completed by one person, and no possibility of mismatching is generated, so that the hemostatic dressing has the characteristic of operational safety.

Description

technical field [0001] The invention belongs to a dressing for protecting a central venous catheter and a method for using it, in particular to a transparent hemostatic dressing and a method for protecting a central venous catheter. Background technique [0002] Intravenous chemotherapy is a common treatment method for cancer patients. Once the chemotherapy drugs are extravasated during the treatment, it will cause severe chemical burns to the peripheral veins, surrounding subcutaneous tissue and skin, and even persist for a long time. my country's intravenous infusion standard stipulates that a central venous catheter must be used when infusing chemotherapy drugs. In order to prevent central venous catheters from slipping, various medical institutions currently use transparent dressings to protect central venous catheters. [0003] The currently used transparent dressing consists of 4 layers of inner lining paper, adhesive, film, and outer lining paper. The material of th...

AI Technical Summary

Problems solved by technology

Disadvantages: 1. When the patient's disease progresses, when the platelet is lower than 50×10 9 / L, there will be bleeding from the puncture port of the catheter, and the local moisture will easily cause the catheter to slip

2. Blood is a good culture medium for bacteria, which can easily cause catheter blood flow infection

The disadvantages are: 1. It must be completed by two people, which is a waste of human resources

2. The operation process is complicated

3. Long operation time
