[0002] Common central venous catheters in clinical practice mainly include peripherally inserted central venous catheters (PICC) and central venous catheters (CVC). In clinical work, in order to protect the relative sterility of CVC and PICC infusion lines and avoid contamination of body fluids and blood, sterile treatment towels are needed. Patients with long-term indwelling central venous catheters are prone to catheter-related bloodstream infection (CRBSI), especially for critically ill patients in the ICU, which can increase the patient's mortality rate, prolong hospitalization time, and increase hospitalization costs. Chlorhexidine has a strong spectrum of antibacterial and bactericidal effects, and has antibacterial effects on Gram-positive and Gram-negative bacteria. In recent years, domestic and foreign studies have confirmed the effectiveness of chlorhexidine dressings in preventing catheter-related bloodstream infections.
[0003] However, ordinary treatment towels are not convenient for observing the patency of the pipelines and the fixation of each interface at any time, such as whether there is formation of thrombus, clot, precipitation, etc., and the treatment towel and the pipeline cannot be effectively fixed, and displacement of the treatment towel often occurs, which does not play a good protective role.
[0004] For this purpose, a protective treatment towel for the infusion line of central venous catheter is specially proposed. Utility Model Content

[0009] Preferably, the elastic stretchable fixing belt and the fixing ring are respectively arranged in two rows, and the width of the elastic stretchable fixing belt is 1 cm and the length is 4 cm. The spacing between the first and second rows of elastic stretchable fixing belts is 3 cm, and the spacing between the second and third rows of elastic stretchable fixing belts is 6 cm.
[0010] Compared with the prior art, the utility model provides a protective treatment towel for the infusion line of a central venous catheter, which has the following beneficial effects:
[0011] By providing a lower layer of treatment towel, an elastic retractable fixing belt, a fixing ring, a second thorny felt, a second round felt and a transparent window, the pipeline to be fixed is placed on one side of the lower layer of treatment towel, and then one end of the elastic retractable fixing belt is passed through the inside of the fixing ring and turned back to make the second thorny felt and the second round felt adhere to each other, so that the pipeline to be fixed can be fixed. The firmness of the pipeline fixation can be strengthened by multiple elastic retractable fixing belts and fixing rings, so that the pipeline is effectively fixed inside the main body of the treatment towel, and the treatment towel protecting the pipeline is prevented from falling off with the movement of the patient's body position. When the main body of the treatment towel is folded in half, the upper layer of treatment towel will cover the top of the lower layer of treatment towel. Since a transparent window is provided inside the upper layer of treatment towel, the pipeline can be observed at any time through the transparent window, which is convenient for medical staff to observe the fixation and patency of the pipeline in time, thereby improving the treatment effect of medical staff on the patient. When performing operations such as infusion, the pipeline needs to be reconnected, and a small amount of liquid or blood is prone to seepage. The design of the waterproof layer avoids the contamination of the patient's bed unit by liquid or blood. The one-piece chlorhexidine dressing can reduce the occurrence of catheter-related bloodstream infections. The addition of a soft dressing can also act as a buffer, reducing the discomfort caused to the patient's skin by the hard tube. BRIEF DESCRIPTION OF THE DRAWINGS
