[0002] Central venous catheters are widely used in intensive care, chemotherapy, and long-term intravenous infusion. Their connectors are prone to contamination, leakage, or mechanical damage due to exposure, friction, or improper handling, increasing the risk of infection. Current technologies often use sterile gauze wrapping or transparent dressing coverage, but these have the following drawbacks: 1. Insufficient sealing, unable to completely prevent the intrusion of liquids or microorganisms; 2. Repeated opening and operation can easily lead to contamination; 3. The catheter is not securely fixed and is easily dislodged due to patient movement or traction.

[0003] Therefore, this utility model provides a central venous connector protective sleeve to solve the above problems. Utility Model Content
