Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fixation device for a hemodialysis catheter inserted into the jugular vein. Background Technology

[0002] During blood purification treatment, ensuring proper fixation and patency of the hemodialysis catheter is often key to the success of the procedure and the patient's recovery. If the hemodialysis catheter shifts or falls off, it can cause pain during repositioning, delay treatment effectiveness and time, or even lead to infection and endanger the patient's life.

[0003] In existing technologies, medical tape is typically used to fix intravenous catheters to the cheek, behind the ear, or the edge of the auricle. However, this can affect the movement of the patient's head and easily cause adhesive pressure damage at the adhesion site. Utility Model Content

[0004] The purpose of this invention is to provide a fixation device for a hemodialysis catheter inserted into the jugular vein. Its advantages are: by wearing an elastic fixation strap and attaching the Velcro front and back together, the hemodialysis catheter can be easily and quickly fixed, improving the patient's wearing comfort.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fixing device for inserting a hemodialysis catheter into the jugular vein, comprising an elastic fixing band, wherein the first and last parts of the elastic fixing band are respectively provided with a Velcro front side and a Velcro back side that are attached to each other, and two sets of fixing components for fixing the catheter are symmetrically provided on the elastic fixing band.

[0006] The fixing component includes a base disposed on the surface of the elastic fixing band, a first fixing plate disposed on one side of the base, a vertical plate disposed on the other side of the top side of the base, a second fixing plate slidably connected to the side of the vertical plate opposite to the first fixing plate by a compression spring, and a pull rope through the vertical plate being installed on the back of the second fixing plate.

[0007] With the above technical solution, when in use, pulling the pull cord pulls the second fixing plate, placing the catheter between the first and second fixing plates. Releasing the pull cord pushes the second fixing plate under the elastic force of the compression spring, causing the second fixing plate to press the catheter against the first fixing plate, thus fixing the catheter in place. At this time, an elastic fixing strap is worn, and the Velcro front and back are glued together to easily and quickly fix the hemodialysis catheter, improving the patient's wearing comfort.

[0008] The present invention is further configured such that: a groove adapted to the conduit is provided on one side of the first fixing plate and the second fixing plate opposite to each other.

[0009] The present invention is further configured such that: a rubber pad is provided in the groove, and the surface of the rubber pad is densely covered with anti-slip texture.

[0010] The present invention is further configured such that: a sliding groove is provided on the top side of the base along the length direction, and a slider that slides in the sliding groove is provided on the side of the second fixing plate that abuts against the base.

[0011] The present invention is further configured such that a pull ring is installed at the end of the pull rope away from the second fixed plate.

[0012] The present invention is further configured such that: the elastic fixing band is provided with a covering cloth for surrounding the fixing component.

[0013] In summary, during use, pulling the pull cord pulls the second fixing plate, placing the catheter between the first and second fixing plates. Releasing the pull cord pushes the second fixing plate under the elastic force of the compression spring, causing the second fixing plate to press the catheter against the first fixing plate, thus securing the catheter. At this point, the elastic fixing strap is worn, and the Velcro side and the Velcro backing side are fastened together for convenient and quick fixation of the hemodialysis catheter, improving patient comfort.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example 1: Refer to as follows Figure 1-3As shown, a fixation device for inserting a hemodialysis catheter into the jugular vein includes an elastic fixation band 1. The ends of the elastic fixation band 1 are respectively provided with a Velcro front side 2 and a Velcro back side 3 that are attached to each other. Two sets of fixation components for fixing the catheter are symmetrically arranged on the elastic fixation band 1. The fixation components include a base 5 provided on the surface of the elastic fixation band 1. A first fixation plate 6 is provided on one side of the base 5. A vertical plate 10 is provided on the other side of the top side of the base 5. A second fixation plate 7 is slidably connected to the side of the vertical plate 10 opposite to the first fixation plate 6 by a compression spring 9. A pull rope 8 is installed on the back of the second fixation plate 7, which passes through the vertical plate 10. A pull ring 13 is installed at the end of the pull rope 8 away from the second fixation plate 7.

[0020] Specifically, during use, pull the pull ring 13, which drives the pull rope 8. The pull rope 8 pulls the second fixing plate 7, placing the catheter between the first fixing plate 6 and the second fixing plate 7. Release the pull rope 8, and under the elastic force of the compression spring 9, push the second fixing plate 7. The second fixing plate 7 presses the catheter against the first fixing plate 6, thus fixing the catheter in place. At this time, wear the elastic fixing strap 1, which is fastened to the Velcro side 2 and the Velcro side 3, making it convenient and quick to fix the hemodialysis catheter and improving the patient's comfort.

[0021] Example 2: The first fixing plate 6 and the second fixing plate 7 each have a groove 14 adapted to the conduit on their opposite sides. A rubber pad is provided in the groove 14. The surface of the rubber pad is densely covered with anti-slip texture. When the conduit is placed in the groove 14, the rubber pad and the anti-slip texture cooperate to improve the fixing effect of the first fixing plate 6 and the second fixing plate 7 on the conduit.

[0022] Example 3: A groove 12 is provided on the top side of the base 5 along the length direction. A slider 11 is provided on the side of the second fixing plate 7 that abuts against the base 5 and slides in the groove 12. The slider 11 drives the second fixing plate 7 to slide in the groove 12, thereby fixing the conduit more stably.

[0023] Example 4: The elastic fixing band 1 is provided with a covering cloth 4 for surrounding the fixing component. The covering cloth 4 is made of transparent material. When the fixing component fixes the conduit, the covering cloth 4 covers the conduit, further fixing the conduit.

[0024] Operating steps: When in use, pull the pull ring 13, which drives the pull rope 8. The pull rope 8 pulls the second fixing plate 7, placing the catheter between the first fixing plate 6 and the second fixing plate 7. Release the pull rope 8, and the second fixing plate 7 will be pushed by the elastic force of the compression spring 9. The second fixing plate 7 will press the catheter against the first fixing plate 6, thus fixing the catheter. At this time, wear the elastic fixing strap 1, which is fastened to the Velcro side 2 and the Velcro side 3 to secure the hemodialysis catheter quickly and easily, improving the patient's comfort. Place the catheter in the groove 14, where the rubber pad and anti-slip texture work together to improve the fixing effect of the first fixing plate 6 and the second fixing plate 7 on the catheter. The slider 11 drives the second fixing plate 7 to slide directionally along the groove 12, thus fixing the catheter more stably. Once the fixing components have fixed the catheter, cover the catheter with the cover cloth 4 to further fix it.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
