Description

Technical Field

[0001] This utility model relates to the field of medical products, and in particular to a fixator for a hemodialysis puncture needle. Background Technology

[0002] A hemodialysis puncture needle is a medical needle used to insert into an arteriovenous fistula during hemodialysis. The hemodialysis puncture needle is connected to a hemodialysis catheter, which in turn is connected to the dialysis equipment. The hemodialysis puncture needle and the hemodialysis catheter draw blood out of the blood vessel for dialysis and then guide the blood back into the blood vessel after dialysis.

[0003] The hemodialysis needle is a butterfly needle with two handles located on either side of the needle tip. Hemodialysis needles need to be secured, and the common method is to use tape. The tape is applied to the needle and then to the patient's skin. However, some patients are allergic to tape, and some patients' skin is fragile due to repeated application and tearing of tape during long-term dialysis. Continuing to use tape can easily cause skin damage. Therefore, a non-adhesive method is needed to secure the hemodialysis needle.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: Most existing methods of fixing puncture needles use medical tape for direct fixation, which has many drawbacks. On the one hand, the adhesiveness of medical tape weakens over time and is affected by secretions such as sweat and oil on the patient's skin surface, making the puncture needle prone to displacement, affecting the dialysis effect, and even potentially causing the puncture needle to fall off, leading to medical accidents; on the other hand, directly using medical tape on the skin can easily cause damage to the patient's skin when it is removed, especially for patients with more fragile skin, which may cause skin allergies, redness, swelling, ulceration, and other problems. Therefore, we designed a hemodialysis puncture needle fixator to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A hemodialysis puncture needle fixator includes a puncture needle, a first fixation sleeve, and a second fixation sleeve. The first and second fixation sleeves are provided at both ends of the outer side of the puncture needle. A medical pad is fixed between the first and second fixation sleeves by an elastic band, and the medical pad is located below the puncture needle. A first and second fixation straps are fixed on both sides of the first and second fixation sleeves. The ends of the first and second fixation straps that are close to each other are connected by Velcro.

[0006] In a preferred embodiment of the hemodialysis puncture needle fixation device provided by this utility model, a pull strap is fixed to the bottom end of the second fixing band.

[0007] In a preferred embodiment of the hemodialysis puncture needle fixator provided by this utility model, a hook surface is fixed to the bottom end of the first fixing band, and an adhesive surface is fixed to the bottom end of the second fixing band, wherein the hook surface and the adhesive surface are bonded together.

[0008] In a preferred embodiment of the hemodialysis puncture needle fixation device provided by this utility model, a limiting groove is provided at one end of the inner side of the medical pad, and the inner side of the limiting groove is slidably connected to the puncture needle.

[0009] In a preferred embodiment of the hemodialysis puncture needle fixation device provided by this utility model, a medical adhesive is provided at the connection point between one end of the puncture needle and the patient, and both ends of the medical adhesive are bonded to the patient.

[0010] As a preferred embodiment of the hemodialysis puncture needle fixation device provided by this utility model, the elastic band has low elasticity.

[0020] Example 1 Please refer to Figures 1-4 A hemodialysis puncture needle fixation device includes a puncture needle 1, a first fixing sleeve 2 and a second fixing sleeve 3. The first fixing sleeve 2 and the second fixing sleeve 3 are provided at both ends of the outer side of the puncture needle 1. A medical pad 5 is fixed between the first fixing sleeve 2 and the second fixing sleeve 3 by an elastic band. The elastic band has low elasticity and the medical pad 5 is located below the puncture needle 1. A first fixing strap 7 and a second fixing strap 8 are fixed on both sides of the first fixing sleeve 2 and the second fixing sleeve 3. The ends of the first fixing strap 7 and the second fixing strap 8 that are close to each other are glued together by Velcro. In use, the puncture needle 1 is inserted into the vein in the patient's arm, and then a medical pad 5 is placed under the other end of the puncture needle 1. At this time, one end of the puncture needle 1 is fixed by the middle position of the first fixing sleeve 2, and the other end of the puncture needle 1 is fixed by the second fixing sleeve 3. Then, the first fixing strap 7 and the second fixing strap 8 are used to wrap around the patient's arm, thereby effectively applying pressure to the first fixing sleeve 2 and the second fixing sleeve 3, so that the first fixing sleeve 2 and the second fixing sleeve 3 can resist and fix the puncture needle 1. The first fixing strap 7 and the second fixing strap 8 are connected by Velcro, which can be adjusted according to the thickness of the patient's arm, thereby effectively fixing the puncture needle 1. Therefore, medical tape is effectively saved and medical tape is prevented from easily damaging the patient's skin when it is removed. This utility model can be effectively recycled, greatly increasing the practicality and convenience of the device. The bottom end of the first fixing band 7 is fixed with a hook surface 9, the bottom end of the second fixing band 8 is fixed with an adhesive surface 10, the hook surface 9 and the adhesive surface 10 are bonded together, and the bottom end of the second fixing band 8 is fixed with a pull strap 11. Specifically, when the first fixing band 7 and the second fixing band 8 are wrapped according to the thickness of the patient's arm, the first fixing band 7 and the second fixing band 8 drive the first fixing sleeve 2 and the second fixing sleeve 3 to limit the puncture needle 1, thereby effectively increasing the stability of the puncture needle 1 when inserted into the patient. When it is necessary to remove the puncture needle 1, the pull strap 11 is pulled to cause the second fixing strap 8 and the adhesive surface 10 to separate from the hook surface 9, thereby effectively removing the puncture needle 1. A limiting groove 6 is provided at one end of the inner side of the medical pad 5. The inner side of the limiting groove 6 is slidably connected to the puncture needle 1. The limiting groove 6 effectively limits the puncture needle 1, thereby preventing the puncture needle 1 from sliding. A medical patch 4 is provided at the connection point between one end of the puncture needle 1 and the patient. Both ends of the medical patch 4 are adhered to the patient. The medical patch 4 is used to protect the connection point between the puncture needle 1 and the patient, and to prevent infection of the patient's needle hole.
