Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hemodialysis nursing technology, and more specifically, it relates to an anti-tangling hemodialysis catheter nursing bag. Background Technology
[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. During hemodialysis treatment, a catheter needs to be connected to the patient and the hemodialysis machine. However, because the catheter is long and suspended, a hemodialysis catheter care bag is needed to suspend and manage it. Existing hemodialysis catheter care bags mainly consist of the bag body, the catheter, and clips. The bag body is used to hold and secure the catheter, which connects the patient to the hemodialysis machine. The clips are used to clamp and fix the catheter to the front of the patient, preventing it from shaking or becoming tangled.
[0003] Existing application number CN202220816932.3 discloses a hemodialysis catheter care bag, including a bag body, a first adhesive buckle, a rigid thin plate, a second adhesive buckle, and a fixing ring. The bag body is divided into a winding part and a fixing part, and the fixing part and the winding part are integrally formed. Three rigid thin plates are evenly distributed on the upper end of the fixing part, and three second adhesive buckles are installed on each of the three rigid thin plates. A connecting strap is installed at one end of the fixing part, and the fixing ring is installed on the inner side of the connecting strap. Based on the above, existing hemodialysis catheter care bags mostly have simple clamp structures and use rigid fixing methods, which can easily lead to excessive compression and bending of the catheter, thereby hindering the smooth flow of fluid inside the tube. Furthermore, due to a lack of sufficient flexibility and protection, the catheter may be easily subjected to accidental pulling or other incidents, leading to safety hazards such as catheter clamp detachment. This not only brings additional physical burden to the patient but may also cause secondary injury. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides an anti-tangling hemodialysis catheter care bag, thus resolving the issues of existing hemodialysis catheter care bags.

[0031] Compared with the prior art, the present invention has the following beneficial effects:
[0032] First, this invention uses two sets of semi-circular winding devices to wind up excessively long catheters. The winding grooves separate the catheters inside the winding device, preventing them from getting tangled and squeezed. Furthermore, the elastic element buffers the contraction force generated by the catheter being pulled, effectively preventing the catheter from being squeezed, damaged, or detached from the connector due to hard pulling. In addition, the warning mechanism emits an audible alert, prompting the catheter to be pulled and checked in time, greatly improving the safety of the catheter during dialysis. Second, this invention has a guiding component to prevent the catheter output angle from deviating, which would cause the catheter to bend too much and affect the infusion effect.
[0033] This invention has advantages such as reducing entanglement, providing pull warnings, and allowing for flexible displacement. It effectively buffers the contraction force generated by the pulling of the catheter, and the warning mechanism emits an audible warning when the catheter is pulled, greatly improving the safety of the catheter during dialysis.

[0052] The anti-winding components include:
[0053] The second restraint strap 3 is fixedly installed at the lower part of the nursing bag body 1. Its function is to hang the nursing bag body 1 on the patient's neck by the first restraint strap 2 and tie it under the patient's armpit by the second restraint strap 3, so that the nursing bag body 1 is suspended in front of the patient's chest and is not easy to fall or shake.
[0054] The anti-winding component also includes:
[0055] Guide slot 501 is formed inside trigger 5;
[0056] Guide rod 601, two sets of guide rod 601 are provided, the two sets of guide rod 601 are fixedly installed at the bottom of the two sets of winding machine 6, and the two sets of guide rod 601 are slidably connected inside the guide groove 501; the function is to push the guide rod 601, the guide rod 601 slides inside the guide groove 501, and the guide groove 501 plays a guiding role when the guide rod 601 moves.
[0057] The anti-winding component also includes:
[0058] The partition plate 502 is fixedly installed inside the guide groove 501;
[0059] Trigger switch 503, two sets of trigger switches 503 are provided, and the two sets of trigger switches 503 are fixedly installed on the upper and lower sides of the partition plate 502;
[0060] The warning mechanism 505 is fixedly installed on the front side of the trigger 5. The warning mechanism 505 and two sets of trigger switches 503 are connected together by a wiring harness to form a switching circuit. Its function is that the warning mechanism 505 is mainly composed of a buzzer, power supply and other accessories. When the trigger switch 503 is triggered, the switching circuit is energized and the warning mechanism 505 emits a sound to provide a warning.
[0061] The anti-winding component also includes:
[0062] The elastic element 504 is provided in two sets, and the two sets of elastic elements 504 are fixedly installed on the upper and lower sides of the partition plate 502.
[0063] The winding groove 602 is provided in two sets, which are opened inside the two sets of winding devices 6. Its function is to wind the conduit inside the two sets of semi-circular winding devices 6. The winding groove 602 separates the conduit inside the winding device 6 to prevent the conduit from getting tangled together and causing compression.
[0064] The specific usage and function of this embodiment are as follows:
[0065] The excessively long conduit is wound inside the two sets of semi-circular winding devices 6. The winding groove 602 separates the conduit inside the winding device 6, preventing the conduit from getting tangled and squeezed, and thus serving to store the excessively long conduit.
[0066] When one end of the conduit is pulled, the wound conduit will contract inward, causing the two sets of winding devices 6 to move inward. The movement of the winding devices 6 drives the guide rod 601 to slide inside the guide groove 501. The movement of the guide rod 601 compresses the elastic element 504 and triggers the switch 503, which energizes the switch circuit and causes the warning mechanism 505 to sound an alarm, prompting the conduit to be pulled and to be checked in time. Moreover, the elastic element 504 also acts as a buffer for the winding device 6 and the guide rod 601, preventing the conduit from being squeezed, damaged, or detached from the connector due to hard pulling.
[0067] Example 2:
[0068] Based on Example 1, such as Figures 1 to 7 As shown, it also includes:
[0069] The guide assembly is located on the front side of the mounting plate 4.
[0070] The guiding components include:
[0071] Arc-shaped groove 401, multiple sets of arc-shaped groove 401 are provided, and multiple sets of arc-shaped groove 401 are opened on the front side of the inside of the mounting plate 4;
[0072] Fixed shaft 402, multiple sets of fixed shaft 402 are provided, and multiple sets of fixed shaft 402 are fixedly installed inside multiple sets of arc grooves 401; the function is that the fixed shaft 402 is installed inside the arc groove 401.

[0075] The fixing clips 7 are provided in multiple sets, and the multiple sets of fixing clips 7 are fixedly installed on the front side of the multiple sets of arc plates 701. The function of the fixing clips 7 is to clamp and fix the catheter, so as to prevent the catheter from shaking or falling off and increasing the burden on the patient. The arc plate 701 rotates inside the arc groove 401 with the fixing axis 402 as the center. The arc groove 401 limits the arc plate 701 and prevents the arc plate 701 from rotating too much.
[0076] The specific usage and function of this embodiment are as follows:
[0077] The catheter is clamped and fixed inside the fixing clip 7. The arc plate 701 rotates around the fixing shaft 402 inside the arc groove 401. The arc groove 401 limits the arc plate 701 to prevent the arc plate 701 from rotating too much. This allows the fixing clip 7 on the upper part of the arc plate 701 to swing at a certain angle, allowing the catheter fixed inside the fixing clip 7 to swing. This prevents the catheter output angle from deviating and avoids the catheter bending angle from being too large, which would affect the infusion effect.
