Description

Technical Field

[0001] This utility model belongs to the field of medical consumables technology, specifically a PICC catheter sutureless fixing buckle dressing. Background Technology

[0002] Peripherally inserted central venous catheters (PICCs) are inserted via puncture into the basilic vein, median cubital vein, cephalic vein, external jugular vein, or great saphenous vein of the upper limb. The catheter reaches the superior or inferior vena cava directly and provides therapeutic benefits to patients requiring long-term intravenous medication, chemotherapy for tumors, or malnutrition requiring intravenous nutritional support. Due to its minimal invasiveness, long retention time, and ability to meet the needs of patients in different conditions, it has been widely used in clinical practice.

[0003] Currently, the PICC catheter dislodgement rate ranges from 5% to 31%. Dislodgement causes displacement of the catheter tip, which increases the incidence of complications such as infection, thrombosis, and phlebitis, and raises the risk of unplanned extubation. If sutures are used to fix the catheter, in addition to supporting biofilm growth and increasing the risk of catheter-related bloodstream infections, the sutures also increase the risk of needlestick injuries. Existing PICC catheters typically use sutureless catheter fixation methods, with Silex being a typical example. Silex is widely used in clinical PICC catheter fixation and has achieved good results. However, the commonly used Silex is relatively expensive in clinical practice, and the placement and removal of Silex by nursing staff is time-consuming and inconvenient. Furthermore, a skin protectant must be applied and allowed to dry before applying Silex, and improper removal can still cause skin damage. Silex also has relatively weak skin adaptability and is costly. Utility Model Content

[0004] The purpose of this invention is to provide a PICC catheter fixation dressing that is sutureless. The fixation method of this PICC catheter fixation dressing is simple, and there is no need to apply a skin protectant in advance. The hydrocolloid dressing layer of hydrocolloid material separates the PICC catheter from the skin. It has low allergenicity and high skin affinity. The structure is simple and easy to produce, with low economic cost and strong skin adaptability. It is also more convenient and quick for medical staff to use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A PICC catheter sutureless fixation dressing includes a hydrocolloid dressing layer with an adhesive lower surface, a release paper layer, and two fixing straps. The fixing straps are positioned opposite each other on both sides of the upper surface of the hydrocolloid dressing layer. The upper and lower ends of the fixing straps are fixedly connected to the upper surface of the hydrocolloid dressing layer, respectively. The wing of the PICC catheter passes through the gap between the fixing strap and the upper surface of the hydrocolloid dressing layer, and the PICC catheter is installed on the hydrocolloid dressing layer through the fixing straps. The release paper layer is detachably disposed on the lower surface of the hydrocolloid dressing layer. The release paper layer includes a left release paper, a middle release paper, and a right release paper laid out from left to right. By tearing off the middle release paper, the left release paper, and the right release paper, the middle, left, and right parts of the hydrocolloid dressing layer are respectively adhered to the skin.

[0007] Furthermore, the middle release paper, left release paper, and right release paper are each provided with a peeling step number to identify the peeling order of the middle release paper, left release paper, and right release paper.

[0008] Furthermore, the middle release paper, left release paper, and right release paper are respectively provided with peeling direction markings to indicate the peeling direction of the middle release paper, left release paper, and right release paper.

[0009] Furthermore, auxiliary dressing tapes with adhesive undersides are respectively provided on both sides of the hydrocolloid dressing layer; pre-tear marks are provided between the auxiliary dressing tapes and the hydrocolloid dressing layer, and the auxiliary dressing tapes are torn off from the hydrocolloid dressing layer along the pre-tear marks; auxiliary release paper is provided on the lower surface of the auxiliary dressing tapes, and the auxiliary dressing tapes are respectively adhered to the hydrocolloid dressing layers at both ends of the PICC catheter after the auxiliary release paper is torn off.

[0010] Furthermore, the lower middle part of the hydrocolloid dressing layer protrudes downwards, and the outer edge of the hydrocolloid dressing layer is arc-shaped.

[0011] Furthermore, the fixing strap is made of elastic rubber.

[0012] After adopting the above technical solution, the present invention has the following beneficial effects:

[0013] 1. This utility model provides a PICC catheter fixation dressing without sutures. The fixation method is simple and does not require the prior application of skin protectant. The hydrocolloid dressing layer of hydrocolloid material separates the PICC catheter from the skin. It has low allergenicity and high skin affinity. The structure is simple and easy to produce, with low economic cost and strong skin adaptability. It is more convenient and quick for medical staff to use.

[0014] 2. This utility model provides a PICC catheter sutureless fixing dressing. The middle release paper, left release paper, and right release paper are respectively provided with peeling step sequence numbers and peeling direction markings to facilitate the operation of medical staff and other operators in the order and direction of tearing the middle release paper, left release paper, and right release paper.

[0015] 3. This utility model provides a PICC catheter-free fixing dressing. A pre-tear line is provided between the auxiliary dressing tape and the hydrocolloid dressing layer. The auxiliary dressing tape and the hydrocolloid dressing layer can be made of the same material. The connection between the auxiliary dressing tape and the hydrocolloid dressing layer is very small, allowing the auxiliary dressing tape to be quickly torn off the hydrocolloid dressing layer along the pre-tear line. After tearing off the auxiliary release paper, the two ends of the PICC catheter can be further adhered to the hydrocolloid dressing layer via the auxiliary dressing tape. This effectively limits relative movement between the PICC catheters and provides good stability.

[0016] 4. This utility model provides a PICC catheter fixation dressing without stitches. The lower middle part of the hydrocolloid dressing layer protrudes downwards to accommodate the length of the PICC catheter. The outer edge of the hydrocolloid dressing layer is arc-shaped, which makes it less likely to form sharp corners after the hydrocolloid dressing layer is adhered to the skin, resulting in a more stable adhesion. In addition, the fixing band is made of elastic rubber and has a certain degree of elasticity, which makes it easy to pass the butterfly wing of the PICC catheter through the gap between the fixing band and the upper surface of the hydrocolloid dressing layer.
