Technical Field
[0001] This utility model relates to the field of PICC catheter maintenance technology, specifically to a device for preventing leakage of disinfectant solution from PICC catheters. Background Technology
[0002] PICC (Peripherally Inserted Central Catheter) placement is a medical technique that involves inserting a thin catheter through a peripheral vein, such as the elbow, with its tip reaching the superior vena cava. It is primarily used for medium- to long-term intravenous infusions (such as chemotherapy and parenteral nutrition), reducing the risk of repeated punctures. The catheter can be retained for several months to a year, but regular maintenance is required to prevent infection or thrombosis.
[0003] Disinfection is a crucial and essential procedure during PICC line placement and maintenance, primarily for infection prevention. To prevent disinfectant leakage, the operator must disinfect with one hand while using absorbent material to block the disinfectant with the other, which can lead to inconvenience.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0015] like Figures 1-5 As shown, this utility model provides a technical solution: a device for preventing leakage of disinfectant solution from PICC catheters, comprising: Base 1; Auxiliary seepage prevention mechanism 2 is installed on the top of the base 1 and is used for seepage prevention protection; Support mechanism 3 is located on top of base 1 and is used to support the arm; The auxiliary seepage prevention mechanism 2 includes a raised seat 21, which is fixedly installed on the top of the base 1. A column 22 is fixedly installed on the top of the raised seat 21. A sliding sleeve 23 is slidably connected to the outer wall of the column 22. A first positioning bolt 24 is threadedly connected to the side of the sliding sleeve 23. The threaded end of the first positioning bolt 24 is in movable contact with the outer wall of the sliding sleeve 23. A gooseneck rod 25 is fixedly connected to the side of the sliding sleeve 23 away from the first positioning bolt 24. In use, the position of the seepage absorption element 29 can be adjusted by adjusting the height of the sliding sleeve 23 on the outer wall of the column 22 or by bending the gooseneck rod 25, thereby improving the flexibility of the seepage prevention point. If the height of the sliding sleeve 23 needs to be adjusted, the first positioning bolt 24 can be loosened first.
[0016] As one implementation method in this embodiment, such as Figure 2 As shown, a connecting block 26 is fixedly connected to the end of the gooseneck rod 25 away from the sliding sleeve 23. An assembly block 27 is detachably connected to the side of the connecting block 26 away from the gooseneck rod 25. The assembly block 27 is installed on the connecting block 26 with screws. If the symmetrical side plate 28 or other structures are damaged, the assembly block 27 can be replaced as a whole.
[0017] As one implementation method in this embodiment, such as Figure 3As shown, a symmetrical side plate 28 is fixedly installed at the bottom of the assembly block 27. A protrusion 281 is fixedly connected to the outer wall of the inner side of the symmetrical side plate 28, and a pull ring 282 is fixedly connected to the outer wall of the symmetrical side plate 28. An absorbent element 29 is detachably connected to the outer wall of the inner side of the symmetrical side plate 28. The symmetrical side plate 28 is made of thermoplastic polyurethane elastomer, which has excellent elasticity and wear resistance, and can maintain good performance in various environments. It is suitable for manufacturing parts that require repeated bending and stretching. The absorbent element 29... 9. During installation, pull the symmetrical side plate 28 from the pull ring 282, then place the absorbent component 29, and then release the pull ring 282. The end of the symmetrical side plate 28 will then return to its original position, securing the absorbent component 29 and completing the installation. The design of the protrusion 281 can improve the stability of the absorbent component 29 installation. The absorbent component 29 is made of medical absorbent cotton material. The absorbent component 29 covers the implantation site of the PICC catheter, which can prevent the problem of disinfectant leakage to this site and ensure the safety of the PICC catheter.
[0018] As one implementation method in this embodiment, such as Figure 4 As shown, the support mechanism 3 includes a cylindrical seat 31, which is fixedly installed on the top of the base 1. A rotating seat 33 is rotatably connected to the inner wall of the cylindrical seat 31, and a second positioning bolt 32 is threadedly connected to the outer wall of the cylindrical seat 31. The threaded end of the second positioning bolt 32 is in movable contact with the outer wall of the rotating seat 33. Through the rotatable connection between the cylindrical seat 31 and the rotating seat 33, the angle of the arm support can be adjusted, avoiding the problem of the patient having difficulty adjusting their own position. After adjustment, tightening the second positioning bolt 32 so that its threaded end fits against the outer wall of the rotating seat 33 can lock the angle.
[0019] As one implementation method in this embodiment, such as Figure 5 As shown, a receiving seat 34 is fixedly installed on the top of the rotating seat 33, and a supporting half-cylinder 35 is fixedly installed on the top of the receiving seat 34. In most cases, PICC catheters are implanted in the arm. The shape design of the supporting half-cylinder 35 can support the arm and facilitate the maintenance of PICC catheters.
[0020] As one implementation method in this embodiment, such as Figure 5 As shown, an arc-shaped rubber plate 36 is detachably connected to the inner cavity of the supporting half-cylinder 35. A nylon strap 37 is fixedly connected to the outer wall of the arc-shaped rubber plate 36, and an arc-shaped sponge inner plate 38 is fixedly connected to the inner wall of the arc-shaped rubber plate 36. The design of the arc-shaped sponge inner plate 38 can improve the softness of the support and increase the patient's comfort. When installing the arc-shaped rubber plate 36 on the supporting half-cylinder 35, the arc-shaped rubber plate 36 is snapped into the supporting half-cylinder 35, and then the ends of the two sets of nylon straps 37 are tied together. This design makes it easy for the user to disassemble and clean the entire arc-shaped rubber plate 36.
[0021] Working principle: When in use, instruct the patient to place their arm on the arc-shaped sponge inner plate 38. The angle of arm support can be adjusted by the rotating connection between the cylindrical seat 31 and the rotating seat 33. After adjustment, tighten the second positioning bolt 32 so that its threaded end fits against the outer wall of the rotating seat 33 to lock the angle. Then, by adjusting the height of the sliding sleeve 23 on the outer wall of the column 22, or by bending the gooseneck rod 25, the position of the aspirating element 29 can be adjusted, so that the aspirating element 29 covers the implantation site of the PICC catheter, avoiding the problem of disinfectant leakage to this site and ensuring the safety of the PICC catheter. During use, the aspirating element 29 can be replaced by pulling the symmetrical side plate 28 from the pull ring 282.
[0022] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
