Description

Technical Field

[0001] This utility model belongs to the field of anti-pulling tube covers, specifically relating to medical catheter anti-pulling tube covers. Background Technology

[0002] A medical catheter anti-removal cap is a device used to prevent patients from removing or displacing medical catheters themselves. Catheters are widely used in medicine, such as intravenous catheters, urinary catheters, and gastric tubes. They are usually used for patients who need long-term intubation, especially in intensive care and post-anesthesia recovery. The purpose is to prevent patients from pulling out the catheter unconsciously, thereby reducing complications and avoiding medical accidents.

[0003] When existing anti-dislodgement covers are used for intravenous catheters, since the catheters are often inserted into the patient's hand, and the hand is one of the most easily moved parts of the human body, the single cover structure is often insufficient to limit the patient's hand and prevent the intravenous catheter from falling out. In addition, the traditional method of wrapping with tape or wearing with rope puts a lot of burden on the patient's hand and greatly affects the patient's comfort during use. Furthermore, in cold weather, the single cover structure is also difficult to provide a heating effect for the patient's hand.

[0004] Therefore, in response to the problems of existing catheter anti-extraction shields being ineffective in preventing the dislodgement of venous catheters in patients' hands and having poor wearing comfort, a medical catheter anti-extraction shield was developed. By adding a protective shell structure, an auxiliary heating structure, a strap fixation structure, and a hand support structure to the anti-extraction shield, it can better limit, fix, and protect the patient's hand and the venous catheter on it, preventing accidental dislodgement, and also improving the patient's comfort when using the device. Utility Model Content
