Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a PICC catheter provided with an anti-compression fixing sleeve. Background Art

[0002] PICC catheterization, or peripherally inserted central venous catheterization, is a procedure that uses a catheter to puncture a vein in the arm. The catheter goes directly to a large vein close to the heart, which can avoid direct contact between chemotherapy drugs and the arm vein. In addition, the blood flow in the large vein is very fast, which can quickly dilute the chemotherapy drugs and prevent the drugs from irritating the blood vessels. At the same time, it can reduce the pain of repeated punctures for patients, has the advantages of long retention time, high safety, convenience and speed, and is widely used in clinical practice.

[0003] In the prior art, after the PICC catheter is inserted into place, its external segment is usually fixed to the patient's skin surface with adhesive tape. However, in this way, the PICC catheter is easy to form a line contact with the patient's skin, and the patient's skin is at a high risk of being crushed during treatment, which affects the patient's comfort during treatment; and the operation steps of fixing the external segment of the PICC catheter with adhesive tape are relatively cumbersome, which reduces the work efficiency of medical staff.

[0004] In response to the above problems, a Chinese utility model patent with application number CN201720119173.4 discloses a PICC protective cover with a catheter fixing device, which includes a PICC protective cover body, and the PICC protective cover body includes a wound fixing cover, a catheter fixing cover and an elastic cover from top to bottom; the wound fixing cover is provided with a transparent window; the catheter fixing cover includes a rectangular film, a catheter fixing groove and waterproof fixing stickers respectively arranged on both sides of the rectangular film; the catheter fixing groove is arranged on the rectangular film, and its shape is curved; the waterproof fixing sticker includes a fixing belt and a waterproof film arranged in sequence from bottom to top; the fixing belt is multiple, and they are respectively arranged on the left and right sides of the rectangular film; the waterproof film is arranged on the side wall of one end of the rectangular film, which can wrap around the PICC protective cover body for several turns, and partially cover the wound fixing cover and the elastic cover inside it. The protective cover of the utility model has the characteristics of ingenious structural design and simple and convenient operation. The device can cover the patient's PICC catheter position in the protective cover, fix the exposed PICC catheter, and prevent it from being pulled and causing pain to the patient. However, there are still some shortcomings, as described below:
