Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary devices, specifically to a PICC catheter fixation clip. Background Technology

[0002] A PICC catheter, or peripherally inserted central catheter, is a thin, flexible intravenous infusion catheter inserted through a superficial vein in the patient's elbow or upper arm, following the vein's course until it reaches a large blood vessel near the heart. To facilitate connection with other medical devices such as syringes and infusion sets, the PICC catheter has a connector at its outer end. To prevent the connector from swinging or snagging during insertion, routine care typically involves directly securing the connector to the patient's limb with a medical dressing. However, due to the connector's rigidity, this method is not only uncomfortable but also carries the risk of swinging or loosening. Utility Model Content

[0003] The purpose of this invention is to provide a PICC catheter fixation clip that is comfortable and has good stability.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is: a PICC catheter fixation clip, comprising an adhesive layer for attaching to the patient's skin and a fixing block fixedly disposed on the upper surface of the adhesive layer, wherein the fixing block is provided with a funnel-shaped mounting groove in the middle for inserting the connector of the PICC catheter. A pair of pressure plates are symmetrically arranged on both sides of the small end of the mounting groove, and the pressure plates form a notch for the PICC conduit to pass through; an eccentric clamping assembly is provided on one side of the large end of the mounting groove, the eccentric clamping assembly includes a locking bolt and a top plate, and a rotating sleeve that cooperates with the locking bolt is provided at the eccentric position of the top plate; a screw hole is provided on the fixing block, and the locking bolt is threadedly engaged with the screw hole, and the top plate is sleeved on the locking bolt through the rotating sleeve.

[0005] Preferably, the top pressure plate is inverted L-shaped.

[0006] Preferably, the fixing block is a plastic sheet.

[0007] Preferably, the top plate is also provided with a small lever.

[0008] Preferably, the lower surface of the locking bolt head is provided with a rubber layer.

[0009] Preferably, it also includes an external dressing for covering the outside of the fixing block.

[0010] The beneficial effects of this invention are mainly reflected in its ability to stably fix the PICC catheter connector, preventing connector movement, and the use of a fixing block as a padding layer to improve comfort after fixation. Specifically, in use, the dressing layer is first applied to the patient's skin as a base. The PICC catheter body is then passed through the notch between the two pressure plates, and the PICC catheter connector is gradually pushed into the mounting groove, with the small end of the connector positioned under the pressure plates. Next, the top plate is rotated until its edge presses firmly against the connector, and then the locking bolt is used to press the top plate tightly onto the fixing block. Because the fixing block acts as a padding layer for the connector, its flat bottom surface ensures comfortable contact with the patient's skin. Simultaneously, the double locking of the top and side using the pressure plates and the top plate improves the stability of the PICC catheter connector. Attached Figure Description

[0011] Figure 1 This is a top view of the structure of this utility model; Figure 2 This is a schematic diagram of the top plate installation. Figure 3 This is a schematic diagram of the top pressure plate structure; Figure 4 for Figure 1 The diagram shown is a schematic representation of the structure in its operational state. Detailed Implementation

[0012] Combination Figure 1-4 As shown, a PICC catheter fixation clip is mainly used to secure the connector of a patient with a PICC catheter, improving overall comfort and stability. Figure 1 As shown, this utility model includes an adhesive layer 1 for attaching to the patient's skin and a fixing block 2 fixedly disposed on the upper surface of the adhesive layer 1. The fixing block 2 is generally a flat plastic block, which is glued to the surface of the adhesive layer 1. It has a larger skin contact area and smooth corners. As a pad for joint installation, it provides good skin comfort and is less likely to cause pressure sores.

[0013] A funnel-shaped mounting groove 4 is provided in the middle of the fixing block 2 for inserting the connector 3 of the PICC conduit. Figure 1 As shown in the diagram, the mounting slot 4 gradually increases in size from top to bottom, as... Figure 4 As shown, connector 3 is inserted from the lower end when fixed.

[0014] A pair of pressure plates 5 are symmetrically arranged on both sides of the small end of the mounting groove 4. The pressure plates 5 are used to press the top surface of the small end of the connector 3. The pressure plates 5 form a notch 7 between them for the PICC conduit body 6 to pass through, so as to facilitate the insertion of the conduit body 6. The size of the notch 7 should be smaller than the size of the small end of the connector 3 and larger than the size of the conduit body 6, so as to facilitate insertion while preventing the small end of the connector 3 from coming out. Figure 3 As shown, the top pressure plate 5 is inverted L-shaped, and it is foreseeable that it could also be other shapes that serve the same function.

[0015] An eccentric clamping assembly is provided on one side of the large end of the mounting groove 4. The eccentric clamping assembly includes a locking bolt 8 and a top plate 9. A rotating sleeve 10 that cooperates with the locking bolt 8 is provided at the eccentric position of the top plate 9. The fixing block 2 is provided with a screw hole, and the locking bolt 8 is threadedly engaged with the screw hole. The top plate 9 is sleeved on the locking bolt 8 by the rotating sleeve 10 and can rotate freely in the unlocked state. To facilitate rotation, a small lever 11 is generally provided on the top plate 9.

[0016] In use, the dressing layer 1 is first applied to the patient's skin as a base. The PICC catheter body 6 is passed through the notch 7 between the two pressure plates 5, and the PICC catheter connector 3 is gradually pushed into the mounting groove 4, so that the small end of the connector 3 is placed under the pressure plate 5. Then, the top plate 9 is rotated until the edge of the top plate 9 presses against the connector 3, and then the locking bolt 8 is used to press the top plate 9 firmly onto the fixing block 2. To improve the tightness, a rubber layer 12 can be provided on the lower surface of the head of the locking bolt 8. Because the fixing block 2 is used as the padding layer for the connector 3, and the bottom surface of the fixing block 2 is flat, it can ensure comfortable contact with the patient's skin. At the same time, the double locking of the top and side using the pressure plate 5 and the top plate 9 can improve the fixation stability of the PICC catheter connector 3. The size of the head of the locking bolt 8 can be adjusted according to the overall size to facilitate rotation operation.

[0017] In addition, the present invention may also include an external patch for covering the fixing block 2. After the fixing is completed, the external patch is used for another external fixing to further ensure the stability of the fixing. Since the external patch needs to be removed when using the connector 3, its adhesiveness can be relatively low so as to be easy to peel off.
