Technical Field

[0001] This utility model relates to the field of fixation device technology, specifically a multifunctional device for fixing indwelling needles. Background Technology

[0002] An indwelling needle, also known as a cannula or intravenous indwelling needle, is a medical device used to temporarily place in a patient's blood vessels. It is mainly used for repeated infusions, blood transfusions, or blood collection to avoid vascular damage and patient pain caused by repeated punctures.

[0003] Currently, after indwelling needle insertion, the needle, tubing, and adapter are mostly fixed to the patient's skin with dressings. This method of fixation has low tightness, and the adhesive effect of the dressing becomes worse after the patient sweats. The tubing and adapter may shift, affecting the indwelling needle. In addition, the adapter is directly exposed to the outside world when not in use, making it easy for dust to accumulate and cause contamination. Utility Model Content
