Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a novel PICC fixation device. Background Technology

[0002] In medical institutions, securing PICC catheters (peripherally inserted central venous catheters) is crucial to prevent catheter displacement, dislodgement, or infection. After insertion, healthcare professionals typically coil the exposed portion of the catheter into a "U" or "L" shape to reduce traction forces during catheter movement; the external portion of the catheter is then horizontally secured with sutureless tape or catheter fixation adhesive, forming an "I" or "butterfly" shape for reinforcement.

[0003] However, in actual use, the above fixation methods may encounter problems such as insecure fixation, dressing curling, or catheter movement. For example, tension during dressing application can cause the edges to easily lift; or skin oils and sweat can affect the adhesiveness of the dressing; catheter movement may be due to insecure fixation, excessive patient activity, or the fixation device being unsuitable for specific situations, such as children or people with sensitive skin; these problems may increase the risk of infection, catheter dislodgement, or thrombosis. Utility Model Content

[0018] Figure 2This is a schematic diagram of another embodiment of the novel PICC fixing device of this utility model;

[0019] Figure 3 This is a schematic diagram of the usage state of the novel PICC fixing device of this utility model. Detailed Implementation

[0020] The implementation of the novel PICC fixing device of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 As shown, this utility model discloses a novel PICC fixing device, comprising an integrally cut and molded braided block 1. The braided block 1 includes a square main block 2, a connecting part 3 extending outward from the upper edge of the main block 2, and an auxiliary block 4 extending outward from the upper edge of the connecting part 3, offset from the connecting part 3. The main block 2 has a first groove 5 cut into its upper edge connecting to the connecting part 3, and a second groove 6 cut into its side edge offset from the first groove 5. Adhesive tape 7 extends outward from both sides of the main block 2 on both sides of the second groove 6. The back of the adhesive tape 7 has Velcro bristles, and the surface of the main block 2 has Velcro round bristles. The auxiliary block 4 has a folding block 8 extending outward from its side or upper edge. After folding back, the folding block 8 is attached to the side edge of the auxiliary block 4 by Velcro. On this braided block, the first groove 5 corresponds precisely to the tube insertion position, and the exposed window of the first groove 5 ensures the exposure of the tube plug position, ensuring comfort and easy observation. The woven block 1 is wrapped around the arm after corresponding to the tube placement position, and the adhesive tape is wrapped back to the surface of the main block 2 for bonding to achieve fixation.

[0022] Figure 1 In the specific example shown, the folding block 8 is a block-shaped part that extends outward from the top of the auxiliary block part 4. The surface of the folding block 8 after folding back is provided with Velcro round bristles. Wings 40 extend outward from the middle of both sides of the auxiliary block part 4. The surface of the wings 40 is provided with Velcro barbs. In this way, after the folding block 8 is folded back, the wings are glued to the surface of the folding block to achieve fixation.

[0023] exist Figure 2 In another example shown, the folding block 8 is a block-shaped part extending outward from the side of the auxiliary block part 4. The folding block 8 has Velcro barbs on the side away from the auxiliary block part 4, and the auxiliary block part 4 has Velcro round bristles on the side away from the folding block 8. In this way, the folding block 8 can be directly pasted to the side of the auxiliary block part 4 after folding back to achieve fixation.

[0024] Further, the auxiliary block 4 is fixed, and its back is provided with horizontally arranged straps 9 extending outward from both sides. The ends of the straps 9 on both sides are connected by adhesive or Velcro. In an improved embodiment, the straps 9 are fixed to the auxiliary block 4 in a detachable manner. There are several ways to detach them. For example, the straps 9 have Velcro bristles in the middle and Velcro round bristles in the corresponding position on the auxiliary block 4 to achieve adhesion between the two; or, the straps 9 have an adhesive layer in the middle, which is directly attached to the auxiliary block 4 and can be peeled off when needed. This technical feature makes its use more flexible. When used on specific areas such as the shoulders, the auxiliary block 4 does not need to be fixed, and the straps 9 can be removed at this time.

[0025] The woven block described in this invention can be made of conventional woven materials, specifically cotton, linen, nylon, polyester fiber, or polyester. The choice of specific materials is not limited; cotton can be used to ensure comfort and breathability, while cotton can be used to ensure better fixation. The entire woven block can be sewn together with a high-stiffness nylon layer as the upper layer and a cotton layer as the lower layer.

[0026] The aforementioned hook and loop fasteners and loop fasteners are both hook and loop fastener blocks used in the market. The hook and loop fasteners and loop fasteners are both connected to the woven block by sewing.

[0027] To more rationally design the shape of the fixing device and match the shape of the exposed tube, the depth of the first groove is 1.5-3.5cm, and the width of the first groove is 1-3cm. The longitudinal height of the connecting part 3 is 0.5-2cm; the length of the main block is 8-14cm, and the longitudinal height is 4-6cm.

[0028] In use, press the main block onto the U-shaped insertion tube, ensuring the first groove corresponds precisely to the tube insertion position. After securing the main block, wrap the adhesive tape back around its surface for bonding, thus securing it. Then, wrap the U-shaped insertion tube around the auxiliary block near the first groove, placing the insertion connector above the auxiliary block. Fold the folded-back block back and adhesively seal it, wrapping the insertion connector. Figure 3 As shown.
