Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a PICC catheter fixing device. Background Art

[0002] PICC catheters are suitable for patients who need long-term intravenous infusion. Their characteristics include soft and durable material, and X-ray visualization. They can effectively reduce damage to their own blood vessels and alleviate pain. They are particularly suitable for patients undergoing long-term chemotherapy or long-term infusion.

[0003] In Chinese Patent 202122334096.3, the utility model belongs to the technical field of medical consumables, specifically a PICC catheter fixing device, including gauze, the gauze is provided with a perforation, a catheter is passed through the perforation, a fixing sleeve is fixedly connected to the front of the gauze, the catheter passes through the fixing sleeve, fixing tapes are provided on both sides of the fixing sleeve, and a positioning tape is fixedly connected to the back of the gauze; the utility model fixes the catheter by gauze, and fixes the gauze by positioning tape, and there is no need to stick the positioning tape on the patient's skin, which can effectively avoid skin allergies of the patient, and also avoid discomfort to the patient. It is convenient and practical, and has a good fixing effect.

[0004] The existing PICC catheter fixing device uses gauze and tape to cooperate with each other to limit and fix the catheter. However, the gauze and tape are both relatively soft in texture, and they only have a fixing effect on the catheter but no supporting or protective effect. During the process of using the catheter for infusion, if the catheter is accidentally squeezed, the catheter will be deformed and blocked, affecting the normal circulation of the liquid medicine. In addition, the existing device uses tape to fix the joint of the catheter. The joint of the catheter has an irregular shape, and the catheter needs to be fixed on the patient's body for a long time. When putting on and taking off clothes, the irregularly shaped catheter joint is very easy to scratch clothes, which is easy to generate a pulling force on the catheter. If this pulling force is too large, it may cause the catheter to fall off, causing harm to the patient.

[0005] Therefore, a PICC catheter fixing device is proposed to solve the above problems. Utility Model Content
