Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fixation device technology, and specifically relates to an anti-dislodgement device for PICC catheters. Background Technology
[0002] A PICC catheter, or peripherally inserted central catheter, is a medical device that is inserted directly into a large vein near the heart through a puncture in the patient's arm. The main function of this catheter is to avoid direct contact between chemotherapy drugs and the arm veins, utilizing the faster blood flow in the large vein to quickly dilute the chemotherapy drugs, thereby reducing drug irritation to the blood vessels. However, because PICC catheters need to remain in the patient's body for extended periods, they require external fixation.
[0003] Current fixation methods primarily involve using adhesive tape, but this method cannot meet the needs of long-term fixation and requires frequent replacement to clean the wound site and prevent infection and skin diseases. Furthermore, due to the patient's arm movements, the PICC catheter is prone to loosening, leading to catheter displacement, treatment interruption, or even adverse consequences such as infection and local bleeding.
[0004] Patent documents have disclosed an anti-dislodgement device for PICC catheters. Although it can fix the catheter, the fixing effect is not ideal because the eccentric rotating disk one and rotating disk two are relatively movable. In actual application, the catheter is also easily moved or deviated by external forces.
[0005] Therefore, it is necessary to design an anti-dislodgement device for PICC catheters to solve the above-mentioned technical problems. Summary of the Invention
[0006] To solve the above technical problems, this utility model proposes an anti-dislodgement device for PICC catheters.
[0007] The technical solution of this utility model is:
[0008] This utility model proposes an anti-dislodgement device for PICC catheters, comprising:
[0009] A wristband, wherein a locking part and an adjusting part are respectively provided on the wristband, the locking part and the adjusting part cooperate to make the wristband form a loop, and a base is provided in the middle of the wristband;
[0010] catheter;
[0011] A flexible telescopic clamp is connected to the base; the flexible telescopic clamp is used to clamp the conduit.
[0012] Two symmetrical connectors are provided, which are connected to the outer wall of the flexible telescopic clip. The two connectors are located on both sides of the opening of the flexible telescopic clip. Two symmetrical Velcro fasteners are provided on the inner side of each connector, and the Velcro fasteners on the two connectors can be glued to each other.
[0013] Preferably, the flexible telescopic clamp has an inner gasket inside, and the inner gasket is sleeved with the conduit.
[0014] Preferably, the two connectors are fitted with adjusting rods, one end of which is connected to a limit plate, and the other end of which is threaded with an adjusting cap.
[0015] Preferably, the adjusting rod is located between two symmetrical Velcro straps.
[0016] Preferably, the locking part includes a snap base, which is connected to the wristband;
[0017] The adjustment part includes a plurality of snaps arranged at equal intervals. The snaps are connected to the wristband, and the end of the snap away from the wristband cooperates with the end of the snap base away from the wristband.
[0018] Preferably, both the locking part and the adjusting part are Velcro 2, and the two Velcro 2 are connected to the wristband and cooperate with each other.
[0019] This utility model has the following advantages and effects compared with the prior art:
[0020] (1) The design of wristband and flexible telescopic clip can effectively fix the catheter and prevent it from loosening or shifting when the patient moves, thereby improving the stability of the catheter and reducing the risk of infection or local bleeding caused by catheter movement.
[0021] (2) The locking and adjusting parts on the wristband allow for personalized adjustments based on the size of the patient's arm, ensuring the comfort and practicality of the device. The adjustable design allows patients to adjust the fixation device according to their own needs, improving patient satisfaction.
[0022] (3) The flexible telescopic clamp is equipped with an inner gasket, which increases the friction with the catheter and thus enhances the fixation effect. At the same time, the design of the inner gasket avoids direct contact between the flexible telescopic clamp and the catheter, preventing scratches on the outer wall of the catheter.
[0023] (4) Two connectors are fitted with adjustment rods, which allow for fine-tuning of the position of the connectors to accommodate different sizes of conduits, improving the adaptability of the device and ensuring that even larger conduits can be securely fixed.
[0024] (5) The design of the adjustment rod enables double locking of the two connectors. The flexible telescopic clamp can only be opened by operating in a specific order, which prevents the catheter from being accidentally dislodged by the patient or other personnel.
[0025] (6) The whole device is small and lightweight, which reduces the pressure on the patient's skin and improves the patient's quality of life. When wearing it, the patient can carry out daily activities more freely and will not restrict their movements excessively because of the fear of the catheter falling off.
[0026] In summary, this invention not only improves the stability of catheter fixation and reduces the risk of catheter loosening or displacement, but also improves the continuity and safety of treatment, thereby enhancing the overall treatment experience for patients. Attached Figure Description

[0040] To enable those skilled in the art to better understand this utility model, the present utility model will now be further described in conjunction with specific embodiments.
[0041] Example 1:
[0042] like Figure 1 As shown, this utility model provides an anti-dislodgement device for PICC catheters, comprising:
[0043] Wristband 1, with a locking part and an adjusting part respectively provided on the wristband 1, the locking part and the adjusting part cooperate to make the wristband 1 form a loop, and a base 10 is provided in the middle of the wristband 1;
[0044] Catheter 2;
[0045] The flexible telescopic clamp 3 is connected to the base 10; the flexible telescopic clamp 3 is used to clamp the conduit 2.
[0046] Two symmetrical connectors 4 are connected to the outer wall of the flexible telescopic clip 3, and the two connectors 4 are located on both sides of the opening of the flexible telescopic clip 3. Two symmetrical Velcro straps 5 are provided on the inner side of each connector 4, and the Velcro straps 5 on the two connectors 4 can stick to each other.
[0047] The flexible telescopic clamp 3 has an inner gasket 6 inside, which is sleeved with the conduit 2.
[0048] Two connectors 4 are inserted with adjusting rods 7. One end of the adjusting rod 7 is connected to a limit plate 70, and the other end of the adjusting rod 7 is threaded with an adjusting cap 8.
[0049] The adjusting lever 7 is located between two symmetrical Velcro straps 5.
[0050] The locking part includes a snap base 9, which is connected to the wristband 1;
[0051] The adjustment part includes several equally spaced snaps 90. The snaps 90 are connected to the wristband 1, and the end of the snap 90 away from the wristband 1 cooperates with the end of the snap base 9 away from the wristband 1.
[0052] Working principle: Wristband 1 is wrapped around the patient's arm. Through the cooperation of the locking part and the adjusting part, wristband 1 is fixed tightly and comfortably on the arm. According to the size of the patient's arm, one of the snap buttons 90 is selected to cooperate with the snap button base 91, which improves the practicality of the device and allows for personalized adjustment according to the size of the patient's arm.
[0053] The flexible telescopic clamp 3 is located on the base 10 and is used to clamp the catheter 2. The flexible telescopic clamp 3 increases the friction with the catheter 2 through the inner gasket 6, thereby enhancing the fixing effect. At the same time, the design of the inner gasket 6 avoids direct contact between the flexible telescopic clamp 3 and the catheter 2, thus avoiding scratching the outer wall of the catheter 2.
[0054] When the two Velcro straps 5 are glued together, the two connectors 4 are connected, which further enables the flexible telescopic clip 3 to clamp the catheter 2, and further improves the clamping effect on the catheter 2.
[0055] For larger conduits 2, the two Velcro fasteners that fit together can easily loosen or even fall off. In this case, the flexible telescopic clamp 3 cannot effectively hold the conduit 2. Adjusting rods 7 are inserted into the two connectors 4. One end of the adjusting rod 7 is connected to a limit plate 70, and the other end is threaded to an adjusting cap 8. For larger conduits 2, by inserting the adjusting rod 7 and tightening the adjusting cap 8, the position of the two connectors 4 can be finely adjusted, further enhancing the gripping effect of the flexible telescopic clamp 3 on the conduit 2. This improves the adaptability of the device and prevents the conduit 2 from shifting. While being flexible, it can also accommodate catheters 2 of different thicknesses. Through the design of Velcro 5 and adjustment rod 7, the two connectors are double-locked. The flexible telescopic clip 3 can only be opened by operating in a specific order to prevent the catheter 2 from being accidentally dislodged by the patient or other personnel. The flexible telescopic clip 3 is small and lightweight, reducing the pressure on the patient's skin and improving the patient's quality of life. When wearing it, the patient can perform daily activities more freely (slight arm movements, dressing) without being overly restricted in their movement due to the fear of the catheter 2 dislodging, thereby improving the patient's quality of life.
[0056] In summary, this invention not only improves the fixation stability of catheter 2 and reduces the risk of catheter 2 loosening or displacement, but also reduces the risk of infection, thereby improving the continuity and safety of treatment.
[0057] Example 2:
[0058] In embodiment 2 of this utility model, using Figure 2 The following description will be provided. Furthermore, descriptions of parts that are no different from those in Embodiment 1 will be omitted, and the same reference numerals will be used instead.
[0059] like Figure 2 As shown, this utility model relates to an anti-dislodgement device for PICC catheters, wherein the locking part and the adjusting part are both Velcro 91, and the two Velcro 91 are connected to the wristband 1 and cooperate with each other.
[0060] Working principle:
[0061] To secure the wristband 1, the patient wraps the wristband 1 around the arm, ensuring that the base 10 is located in the middle of the arm. The wristband 1 has Velcro 5 and Velcro 91. The Velcro 5 and Velcro 91 are attached together accordingly, and the adhesive surfaces of the Velcro will be firmly bonded, thereby securing the wristband 1 and the catheter 2.
[0062] In summary, this invention not only improves the fixation stability of catheter 2 and reduces the risk of catheter 2 loosening or displacement, but also reduces the risk of infection, thereby improving the continuity and safety of treatment.
[0063] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
