Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a central venous catheter protection device. Background Technology

[0002] In the medical field, the secure fixation of central venous catheters is crucial for patient treatment. In current medical procedures, healthcare professionals typically cover the central venous catheter infusion connector and tubing connection with sterile gauze and then wrap it with tape to ensure safety. However, during patient examinations, it is difficult for healthcare professionals to check for bleeding or drug leakage at the connector, necessitating frequent removal of the gauze for inspection to ensure timely detection of problems. But with repeated application of tape, its adhesiveness weakens, causing the gauze to loosen and expose the connector, posing a potential risk. Furthermore, during patient movement, the catheter is easily pulled, and the poor fixation of the gauze increases the risk of catheter dislodgement.

[0003] For patients with thin skin, allergies to adhesive tape, or excessive sweating, traditional tape fixation methods present numerous problems. For those with thin skin, tape application can easily cause skin damage; for those allergic to adhesive tape, contact with the skin can trigger allergic reactions; and for those who sweat excessively, sweat can affect the adhesiveness of the tape, increasing the risk of catheter dislodgement and displacement. Currently, there is a lack of an ideal fixation method specifically designed for these special patients, which not only causes patient discomfort but may also affect treatment outcomes and even lead to complications such as infection.
