Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fixation device for an internal neck hemodialysis catheter. Background Technology

[0002] Hemodialysis is currently an effective treatment for end-stage renal disease. Hemodialysis catheters are a type of access for hemodialysis in uremia patients. A good dialysis access is key to ensuring the quality of dialysis. Currently, the most common types of dialysis catheters in clinical practice are internal jugular vein dialysis catheters and femoral vein dialysis catheters. The fixation method is to wrap the surface with sterile gauze and then fix it with ordinary non-woven tape. When there is a lot of sweating, the adhesion may be poor, which may lead to catheter slippage or accidental removal.

[0003] Replacing non-woven tape with a catheter fixation device provides better catheter securement. For example, Chinese Patent Publication No. CN215023442U discloses a temporary intracervical dialysis catheter fixation device, including a neck ring, loops, and a fixing component on the side of the neck ring for securing the dialysis catheter. The neck ring has threaded grooves near the two loops. The fixing component includes a plastic sleeve with notches for inserting the dialysis catheter, a threaded shaft on the plastic sleeve for threaded connection within the threaded grooves, and a rubber ring fitted onto the threaded shaft for abutting against the plastic sleeve and the neck ring. This invention has the following advantages and effects: the loops at both ends of the neck ring are suspended and fixed to the patient's ears; the dialysis catheter can be inserted and fixed after being inserted through the notches in the plastic sleeve; and because the threaded shaft on the plastic sleeve has a rubber ring, when the threaded shaft is tightened into the threaded hole of the neck ring, the rubber ring abuts against the plastic sleeve and the neck ring, allowing adjustment of the angle of the plastic sleeve to accommodate the extension angle of the dialysis catheter.

[0004] In practice, the guide rod is fixed by hanging the neck collar around the patient's neck and the ear loops around the patient's ears, in conjunction with the fixing device. However, it is difficult to effectively fix the neck collar by relying solely on the pair of ear loops. When the patient is confused and moves their head, the neck collar is prone to slipping, resulting in poor fixation. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that rely solely on a pair of ear loops to secure the neck ring effectively, and to propose a neck dialysis tube fixing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A neck fixation device for an internal hemodialysis catheter is designed, comprising an elastic body, a support member at the middle end of the elastic body, and ear-shaped parts at both ends of the elastic body via an adjustment assembly. The adjustment assembly is used to adjust the length of the ear-shaped parts, and the elastic body is hung on the patient's neck via the support member and the ear-shaped parts.

[0008] The bottom of the ear-shaped part is provided with a fixing component and an anti-slip structure. The fixing component is used to fix the dialysis tube, and the anti-slip structure is used to fix the elastomer.

[0009] Furthermore, the adjustment component includes a mounting part, which is fixedly connected to the elastic body. The ear part has a U-shaped structure, with one top end being arc-shaped and one bottom end being bent. The mounting part has a cavity inside, and its two sides are connected to the cavity to form a pair of relief grooves. The ear part is slidably connected in the relief grooves.

[0010] Furthermore, it also includes an adjusting member, which is threadedly connected to the mounting part. A pair of abutting members are fixedly connected to the inner side of the mounting part. The end face of the abutting member is provided with an anti-slip member. The side of the anti-slip member is provided with the hanging ear through a slot. The adjusting member abuts against the hanging ear to cooperate with the anti-slip member to clamp the hanging ear.

[0011] Furthermore, the anti-slip structure includes a connecting strap, with the bottom of each pair of ear loops movably connected to the connecting strap. The free ends of the pair of connecting straps are connected by a buckle, which is positioned on one side of the patient's face, and the connecting strap abuts against the patient's chin.

[0012] Furthermore, the support member is an arc-shaped sponge, and its top has a contact surface near the patient, which abuts against the back of the patient's neck.

[0013] Furthermore, a silicone sleeve is provided at the end of the ear loop located at one end of the arc shape.

[0014] Furthermore, the elastic body is located in the middle and is divided into two halves. The elastic bodies on both sides are movably inserted into the two sides of the support member, and the elastic bodies and the support member are also fixed by fasteners.

[0015] The present invention provides a neck hemodialysis catheter fixation device with the following advantages: The device features a support member and a pair of loops on an elastic body. When the loops are attached to the patient's ears and the support member is in contact with the back of the patient's neck, the elastic body can be securely attached to the patient's neck. Furthermore, a pair of connecting straps are secured with buckles to the patient's chin, providing support and preventing slippage due to head rotation when the patient is unconscious. Additionally, the loops can be unlocked or secured by rotating the adjustment member, allowing for quick adjustment of their length to accommodate different neck sizes in different patients.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A neck hemodialysis catheter fixation device includes an elastic body 1, a support member 2 at the middle end of the elastic body 1, and ear loops 4 at both ends of the elastic body 1 via an adjustment assembly 3. The adjustment assembly 3 is used to adjust the length of the ear loops 4, and the elastic body 1 is hung on the patient's neck via the support member 2 and the ear loops 4.

[0024] The bottom of the ear-shaped part 4 is provided with a fixing member 5 and an anti-slip structure 6. The fixing member 5 is used to fix the dialysis tube, and the anti-slip structure 6 is used to fix the elastomer 1.

[0025] Furthermore, the adjustment component 3 includes a mounting part 31, which is fixedly connected to the elastic body 1. The ear part 4 has a U-shaped structure, with one end of its top being arc-shaped and one end of its bottom being bent. The mounting part 31 has a cavity inside, and the two sides of the cavity are connected to form a pair of relief grooves 311. The ear part 4 is slidably connected in the relief grooves 311.

[0026] Furthermore, it also includes an adjusting member 32, which is threadedly connected to the mounting part 31. A pair of abutting members 33 are fixedly connected to the inner side of the mounting part 31. The end face of the abutting member 33 is provided with an anti-slip member 331. The side of the anti-slip member 331 is provided with the hanging ear 4 through the slot 332. The adjusting member 32 abuts against the hanging ear 4 to cooperate with the anti-slip member 331 to clamp the hanging ear 4.

[0027] It is worth mentioning that the elastomer 1 is preferably made of materials with elastic deformation capabilities such as rubber and silicone, so as to be hung on the patient's neck. The anti-slip part 331 can be an anti-slip pad or a silicone pad, etc. The adjusting part 32 is threadedly connected to the mounting part 31. By abutting against the ear hanging part 4, the anti-slip part 331 clamps the ear hanging part 4, thereby adjusting and fixing the length of the ear hanging part 4.

[0028] Furthermore, because the ear part 4 has a U-shaped structure and is slidably connected to the relief groove 311, the relief groove 311 can circumferentially lock the ear part 4 and provide relief space for the ear part 4 to prevent the ear part 4 from being unable to be clamped and fixed.

[0029] More specifically, the anti-slip structure 6 includes a connecting strap 61, and the bottom of each pair of ear loops 4 is movably connected to the connecting strap 61. The free ends of the pair of connecting straps 61 are connected by a buckle 62, which is positioned on one side of the patient's face, and the connecting strap 61 abuts against the patient's chin.

[0030] It is worth mentioning that the buckle 62 is a buckle used for connecting backpack straps in the prior art, mainly including a docking part and a fixing part. The fixing part is inserted into and fixed to the docking part. Of course, the fixing part can also be unlocked to make it detach from the docking part.

[0031] Furthermore, the connecting strap 61 is preferably an elastic nylon strap. The two connecting straps 61 are of different lengths. After being snapped together by the buckle 62, they are positioned on one side of the patient's face to ensure that the longer connecting strap 61 contacts the patient's chin and prevents the elastomer 1 from detaching from the neck.

[0032] It should be added that the fixing member 5 can be a spring clip or a plastic sleeve with a notch, and the conduit is fixed by being snapped into the plastic sleeve through the notch.

[0033] In general, the support member 2 is an arc-shaped sponge, and its top is provided with a contact surface 21 near the patient, which abuts against the back of the patient's neck.

[0034] By using the support 2 in conjunction with a pair of ear loops 4, the elastomer 1 can be better hung on the patient's neck, and the patient's neck will not feel any discomfort.

[0035] Finally, the ear loop 4 is provided with a silicone sleeve 41 at one end of the arc shape.

[0036] Furthermore, the elastic body 1 is located in the middle and is divided into two halves. The elastic bodies 1 on both sides are movably inserted into the two sides of the support member 2, and the elastic body 1 and the support member 2 are also fixed by fasteners.

[0037] Furthermore, the fasteners are screws, and the elastic body 1 and the support 2 are fixed by threaded connection screws. After the elastic body 1 on both sides is separated from the support 2, it is easy to maintain and replace, avoiding the situation where the whole body is replaced when one side is damaged.

[0038] Working method: During operation, the elastomer 1 is hung on the patient's neck, the support 2 is in contact with the back of the patient's neck, a pair of ear hooks 4 are hung on the patient's ears, and a pair of connecting straps 61 are connected by buckles 62. The connecting straps 61 support the elastomer 1 by contacting the patient's chin. When the patient is in a state of confusion, turning their head will cause the elastomer 1 to slip off.

[0039] When the length of the ear part 4 needs to be adjusted, rotate the adjusting member 32 to disengage it from the ear part 4, pull the ear part 4 to move it to a suitable position, and then rotate the adjusting member 32 to move it in conjunction with the anti-slip member 331 to clamp the ear part 4 and fix the ear part 4.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
