Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to a needle fixation dressing for infusion ports. Background Technology
[0002] With the development of intravenous therapy technology, venous access ports have been increasingly used in various clinical departments. When using an access port for infusion, a special puncture needle (butterfly needle) is required for puncture. However, due to the special structure of the butterfly needle, which has a wing on each side of the needle body, the two wings are at a 90-degree angle to the needle body after puncture.
[0003] In existing technologies, after the infusion port needle is inserted, the needle position is fixed in size, but there is usually a gap between the needle and the port body. Clinically, a large piece of gauze is usually folded multiple times to form a square with an area larger than the wings on both sides of the butterfly needle, and placed in the gap between the patient's skin and the wings for support, and also to prevent the wings from chafing the skin. At the same time, in order to fix and observe the puncture site of the butterfly needle, a transparent dressing is used to cover the entire butterfly needle. However, this method of using gauze to elevate the needle requires pre-cutting and folding the gauze, and the broken parts of the gauze will produce thread ends and debris, which can easily contaminate the skin. At the same time, the gauze is prone to displacement after being placed under the needle wings. Therefore, a special needle fixation dressing for infusion ports is designed to change the above technical defects. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a special needle fixation dressing for infusion ports. The main purpose of this medical auxiliary device is to solve the technical problems of using gauze to raise the needle wings in the existing technology, which is not only time-consuming and easy to contaminate the skin, but also easy for the gauze to shift.
[0006] (2) Technical solution
[0007] To solve the above-mentioned technical problems, this utility model provides a special needle fixation dressing for infusion ports, including a flexible pad, a transparent dressing fixedly connected to one end of the flexible pad, two support pads fixedly connected to the upper surface of the flexible pad, a folded cloth fixedly connected to the side of the two support pads that are far apart from each other, a hook and loop fastener fixedly connected to the upper surface of both ends of the folded cloth, a hook and loop fastener fixedly connected to the upper surface of the support pad at a position corresponding to the hook and loop fastener, an arc-shaped groove opened in the middle of the upper surface of one end of the flexible pad, and an arc-shaped hole opened in the middle of the other end of the flexible pad.
[0008] Preferably, the size of the transparent dressing is larger than the size of the flexible pad.
[0009] Furthermore, the two support pads are symmetrically distributed, and limit grooves are provided on the upper surface of the side of the two support pads that are close to each other.
[0010] Furthermore, the support pad has an internal cavity, and a corrugated expansion pad is fixedly connected to the center of the support pad's perimeter.
[0011] Furthermore, a support block is fixedly connected to the middle of the inner top wall of the cavity, and the lower surface of the support block is in contact with the inner bottom wall of the cavity.
[0012] Furthermore, a connecting pipe is fixedly connected to the inner wall of one end of the cavity, and the other end of the connecting pipe extends to the outside of the support pad and is fixedly connected to an air storage bag.
[0013] Furthermore, a one-way valve is installed inside the connecting pipe, and the lower surface of the air reservoir is fixedly connected to the upper surface of the flexible pad.
[0014] (3) Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention features a support pad on a flexible pad, with a limiting groove and a folded fabric. The flexible pad and support pad fill the gap between the needle and the skin. The limiting groove limits and supports the needle wings. By folding the folded fabric and bonding the hook and loop sides of the Velcro to the hook and loop sides, the position of the needle is fixed. By squeezing the air reservoir, air is injected into the cavity through the connecting tube, causing the cavity to expand and form a corrugated stretch pad, thus raising the height of the support pad and allowing it to fully contact the needle wings. Finally, a transparent dressing is applied. This design can accommodate gaps of different heights between the needle and the skin, making it convenient to use and preventing the flexible pad from shifting.
[0017] This invention connects a flexible pad with a transparent adhesive to form a whole, and seals the bottom of the flexible pad with a release film to form a closed whole, which not only avoids external contamination, but also facilitates use. Attached Figure Description

[0025] This specific embodiment is a needle fixation dressing for infusion ports, and its structural schematic diagram is shown below. Figures 1-6 As shown, it includes a flexible pad 1, a transparent adhesive patch 2 fixedly connected to one end of the flexible pad 1, two support pads 3 fixedly connected to the upper surface of the flexible pad 1, a folded cloth 7 fixedly connected to the side of the two support pads 3 that are far apart from each other, a hook and loop fastener 8 fixedly connected to the upper surface of both ends of the folded cloth 7, a hook and loop fastener 6 fixedly connected to the upper surface of the support pad 3 at a position corresponding to the hook and loop fastener 8, an arc-shaped groove 10 is opened in the middle of the upper surface of one end of the flexible pad 1, and an arc-shaped hole 11 is opened in the middle of the other end of the flexible pad 1.
[0026] By separating one end of the transparent dressing 2 from the flexible pad 1, the flexible pad 1 is placed in the gap between the needle and the skin, and the arc-shaped hole 11 is aligned with the position of the infusion port, so that the needle is located between the two support pads 3, and the two needle wings are located on the support pads 3, which can support the two needle wings; by folding the two folded fabrics 7 inward, the folded fabrics 7 can cover one end of the needle wings, and the hook and loop side 8 is bonded to the hook and loop side 6, so that the needle wings are fixed, and one end of the transparent dressing 2 is bonded to the skin. By folding the transparent dressing 2, it covers the entire flexible pad 1 and the other end is bonded to the skin.
[0027] The transparent dressing 2 is larger than the flexible pad 1. A release film is attached to the side of the transparent dressing 2 closest to the flexible pad 1. The release film allows the flexible pad 1 to be wrapped inside the transparent dressing 2, forming a sealed whole to prevent external contamination and making it easy to use.
[0028] In addition, the two support pads 3 are symmetrically distributed, and the upper surface of the two support pads 3 on the side that is close to each other is provided with a limiting groove 5; by placing the needle wing in the limiting groove 5, the limiting groove 5 can limit the needle wing and prevent the needle wing from being displaced.
[0029] In addition, the support pad 3 has a cavity 12 inside, and a corrugated expansion pad 4 is fixedly connected to the center of the perimeter of the support pad 3; by injecting air into the cavity 12, the cavity 12 can be expanded, thereby stretching the corrugated expansion pad 4 and raising the height of the support pad 3.
[0030] In addition, a support block 13 is fixedly connected to the middle of the inner top wall of the cavity 12, and the lower surface of the support block 13 contacts the inner bottom wall of the cavity 12. When the support block 13 contacts the inner bottom wall of the cavity 12, the height of the support pad 3 is at its lowest, and the needle wing can be supported by the support block 13.
[0031] In addition, a connecting pipe 14 is fixedly connected to the inner wall of one end of the cavity 12, and the other end of the connecting pipe 14 extends to the outside of the support pad 3 and is fixedly connected to the air storage bladder 9. A one-way valve is installed inside the connecting pipe 14, and the lower surface of the air storage bladder 9 is fixedly connected to the upper surface of the flexible pad 1. By squeezing the air storage bladder 9, the air inside the air storage bladder 9 can be discharged and discharged into the cavity 12 through the connecting pipe 14, so that the inside of the cavity 12 is inflated and expanded.
[0032] Working principle: During use, peel off the release film to expose the flexible pad 1. Separate one end of the transparent dressing 2 from the flexible pad 1, placing the flexible pad 1 in the gap between the needle and the skin, aligning the arc-shaped hole 11 with the infusion port. Then adjust the position of the flexible pad 1 so that the needle is positioned between the two support pads 3, and the two needle wings are positioned within the limiting grooves 5 on the support pads 3, allowing the support pads 3 to support the two needle wings. Fold the two folded fabrics 7 inward to cover one end of the needle wings, and adhere the hook and loop fasteners 8 and 6 to the hook and loop fasteners, allowing the needle wings to... To fix the transparent dressing 2, one end is attached to the skin. The transparent dressing 2 is then folded over to cover the entire flexible pad 1, and the other end is attached to the skin. When the height of the support pad 3 is insufficient to contact the needle wing, the limiting groove 5 can be aligned with the needle wing. Then, the air reservoir 9 is squeezed to expel the air inside the air reservoir 9 and discharge it into the cavity 12 through the connecting tube 14. This causes the cavity 12 to inflate and expand, separating the bottom of the support block 13 from the inner bottom wall of the cavity 12. This raises the height of the support pad 3, allowing the needle wing to be located within the limiting groove 5. Then, the above process is repeated.
[0033] All technical features in this embodiment can be freely combined according to actual needs.
[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
