Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a traction and fixation device for a three-lumen urinary catheter. Background Technology
[0002] A three-lumen catheter is a medical device designed for patients who require long-term indwelling catheterization. It has three independent lumens: a drainage lumen for urine drainage, a fixation lumen for fixing the catheter position by inflation or water injection, and an irrigation lumen for injecting medication or cleaning solution into the bladder.
[0003] During use, the main tube of the urinary catheter is usually inserted into the patient's body. During the operation, the other end of the urinary catheter is placed. However, due to the normal placement, the urinary catheter lacks fixation and restraint, which affects the smoothness of the operation. At the same time, during subsequent use after insertion, the urinary catheter is prone to tangling and pulling due to its own length limitation, causing the patient to be pulled and thus causing discomfort. Therefore, it is evident that fixation during the application of a three-lumen urinary catheter is particularly important.
[0004] Therefore, in view of the above problems, it is necessary to propose a traction fixation device for a three-lumen urinary catheter. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, the present invention provides a traction and fixation device for a three-lumen urinary catheter.
[0006] The technical implementation scheme of this utility model is as follows: A traction and fixing device for a three-lumen urinary catheter includes an assembly plate, a strap, a connecting block, an mounting ring, a rotating ring, and a clamping block. A strap is provided on each side of the assembly plate. A connecting block is provided at the center of the front side of the assembly plate. An mounting ring is provided on the connecting block. A cavity is opened in the mounting ring, and a notch communicating with the cavity is opened on the front and rear sides of the mounting ring. The two notches are symmetrically arranged to place the label on the three-lumen urinary catheter. The left side wall of the cavity is a fitting end with a serrated pattern. A rotating ring is provided circumferentially around the outer ring of the mounting ring. An insertion port with the same width as the notch is opened on the rotating ring. When the insertion port is aligned with the notch, the label of the three-lumen urinary catheter enters the notch through the insertion port. A clamping block is provided on the inner circumferential surface of the rotating ring that slides in the cavity. The clamping block slides to the left end and abuts against the fitting end to clamp and fix the label placed in the notch.
[0007] In a preferred embodiment of the present invention, a wedge-shaped insert is further included. A slot is provided circumferentially on the lower side wall of the cavity. A wedge-shaped insert is slidably disposed on the rotating ring, passing through the clamping block. The bottom end of the wedge-shaped insert engages with the slot to fix the position between the rotating ring and the mounting ring.
[0008] In a preferred embodiment of the present invention, an elastic element is also included, with an elastic element disposed between the wedge-shaped insert and the rotating ring.
[0009] In a preferred embodiment of the present invention, the device further includes an mounting plate, connecting straps, and protective sleeves. The mounting plate is provided on the lower side of the mounting plate, and three connecting straps are provided at intervals on the mounting plate. Each connecting strap has a protective sleeve at its end. The protective sleeves are used to cover each branch tube adjacent to the three-lumen urinary catheter.
[0010] In a preferred embodiment of the present invention, a limiting plate is also included. A limiting plate is provided on one side of the assembly plate, and the limiting plate abuts against the middle branch tube of the three-lumen urinary catheter.
[0011] In a preferred embodiment of the present invention, the side of the clamping block that is in contact with the fitting end has an arrangement of recessed serrations that are adapted to the fitting end.
[0012] Beneficial effects: 1. By setting up the mounting ring and rotating ring, and utilizing the clamping cooperation of the fitting end and the clamping block, this utility model effectively fixes the label on the three-lumen urinary catheter, thereby achieving the fixation of the urinary catheter, preventing the three-lumen urinary catheter from moving randomly during use, and improving the stability and safety of use.
[0013] 2. By using a wedge-shaped insert, this utility model can fix and release the position of the rotating ring during operation, simplifying the operation process and reducing the difficulty of work for medical staff.
[0014] 3. By using a protective sleeve, this utility model can cover each branch opening when the three-lumen catheter is not in use, preventing external bacteria and contaminants from entering, maintaining the cleanliness and hygiene of the catheter, and reducing the risk of infection.

Detailed Implementation
[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.
[0023] Example: A traction and fixation device for a three-lumen urinary catheter, such as Figures 1-5 As shown, the assembly includes an assembly plate 1, straps 2, connecting blocks 3, mounting rings 4, rotating rings 5, and clamping blocks 52. Straps 2 are fixedly mounted on the left and right sides of the assembly plate 1. The straps 2 are made of elastic material to fit different body types. Velcro or buckles are attached to the ends of the straps 2 for secure fastening, ensuring the stability of the device during use. A connecting block 3 is fixedly mounted at the center of the front side of the assembly plate 1, and a mounting ring is mounted on the connecting block 3. 4. A cavity 41 is formed inside the mounting ring 4, dividing the interior of the mounting ring 4 into two parts: a solid part and a cavity 41. A rectangular notch 44 communicating with the cavity 41 is formed on the front and rear sides of the mounting ring 4. The two notches 44 are symmetrically arranged, allowing the label 101 on the three-lumen urinary catheter 100 to pass through the two notches 44 and be placed within them, thus restricting the position of the label 101. The left side wall of the cavity 41 has a serrated fitting end 43, and a rotating ring 5 is circumferentially arranged on the outer ring of the mounting ring 4. The overall thickness of the rotating ring 5 is smaller than that of the mounting ring 4, allowing the rotating ring 5 to be embedded in the outer surface of the mounting ring 4 and rotate, thereby improving the overall aesthetics of the assembly. A slot 51, with a width matching that of the notch 44, is provided on the rotating ring 5. By pushing the rotating ring 5 to rotate, the slot 51 is aligned with the notch 44, allowing the label 101 of the three-lumen urinary catheter 100 to be inserted into the notch 44 through the slot 51, achieving initial placement of the label 101. A clamping device that slides within the cavity 41 is fixedly provided on the inner circumferential surface of the rotating ring 5. Block 52, the clamping block 52 gradually thins from top to bottom and is in the shape of a double-sided trapezoid. When the clamping block 52 slides to the left end with the rotating ring 5, it will be in contact with the fitting end 43. Since the clamping block 52 has a recessed serrated shape that matches the fitting end 43, the two can be tightly fitted together by the serrations when they are in contact, thereby firmly clamping and fixing the label 101 placed therein, so that the three-lumen urinary catheter 100 is fixed in position, thereby ensuring the stability of subsequent operations and use, thus achieving the effect of traction fixation.
[0024] like Figures 3-5 As shown, it also includes a wedge-shaped insert 53. The lower side wall of the cavity 41 is provided with slots 42 spaced apart along the circumference. The wedge-shaped insert 53, which runs longitudinally through the clamping block 52, is slidably disposed on the rotating ring 5. The side of the slot 42 that fits the wedge-shaped surface of the wedge-shaped insert 53 presents an inclined surface that matches it. Conversely, the other side of the wedge-shaped insert 53 is a flat surface. When the wedge-shaped insert 53 rotates counterclockwise, it can use the wedge-shaped surface to cooperate with the inclined surface of the slot 42 to achieve synchronized movement with the rotating ring 5. Then, the flat surface on the other side of the wedge-shaped insert 53 will restrict the clockwise rotation of the wedge-shaped insert 53, forcing the bottom end of the wedge-shaped insert 53 to engage with the slot 42 to fix the position between the rotating ring 5 and the mounting ring 4 and stabilize the clamping state of the label 101.
[0025] like Figures 3-5 As shown, it also includes an elastic element 54. An elastic element 54 is provided between the wedge-shaped insert 53 and the rotating ring 5. In this embodiment, the elastic element 54 is a spring, which can provide an elastic force for the wedge-shaped insert 53 to perform a reset operation.
[0026] like Figure 1 and Figure 6 As shown, it also includes an mounting plate 6, connecting straps 7 and protective sleeves 8. The mounting plate 6 is provided on the lower side of the mounting plate 1. Three connecting straps 7 are provided at intervals on the mounting plate 6. Each connecting strap 7 has a protective sleeve 8 at its end. The protective sleeve 8 is used to cover each branch tube adjacent to the three-lumen urinary catheter 100, further reducing the risk of external environmental contamination of the three-lumen urinary catheter 100.
[0027] like Figure 6 As shown, it also includes a limiting plate 9, which is provided on one side of the assembly plate 1. The limiting plate 9 abuts against the middle bifurcation of the three-lumen urinary catheter 100, thereby providing additional support and positioning for the three-lumen urinary catheter 100.
[0028] In use, the device is placed on the patient's abdomen using the straps 2 on both sides. Then, the wedge-shaped insert 53 is pulled up, causing the elastic element 54 to deform. The wedge-shaped insert 53 then disengages from the slot 42, allowing the rotating ring 5 to rotate freely along the mounting ring 4. The rotating ring 5 is then pushed clockwise to align the insertion port 51 with the two notches 44. The three-lumen catheter 100 with the label 101 is then removed, and the label 101 is passed through the insertion port 51 and placed between the two notches 44. The wedge-shaped insert 53 is then released, causing the elastic element 54 to reset and the wedge-shaped insert 53 to re-insert into the slot 42. The rotating ring 5 is then pushed counterclockwise, causing the clamping block 52 to move synchronously towards the label 101. As the wedge-shaped insert 53 moves, it adheres to the left side of the slot 42. The inclined surface moves smoothly, causing the clamping block 52 to slide counterclockwise within the cavity 41 of the mounting ring 4. Once the clamping block 52 has moved to its end and is in contact with the label 101, the rotation of the rotating ring 5 stops. At this point, the insertion port 51 is no longer aligned with the notch 44, and the ring body of the rotating ring 5 covers the upper side of the label 101. Subsequently, the wedge-shaped insertion rod 53 stops moving and is embedded in the corresponding slot 42 to lock and fix the position of the rotating ring 5. The label 101 is then firmly placed between the contact end 43 and the clamping block 52, thus fixing the clamping method and ensuring the end position of the three-lumen urinary catheter 100. Other operations on the three-lumen urinary catheter 100 can then be carried out. If necessary, when the three-lumen urinary catheter 100 is no longer needed, the protective sleeve 8 can be used to cover the openings of each branch tube of the three-lumen urinary catheter 100 to prevent contamination by impurities.
