Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a fixation dressing for indwelling needle tubes. Background Technology

[0002] When patients need to establish peripheral access due to illness or energy supplementation, indwelling needles are often used in clinical practice to establish peripheral arterial and venous access. During the use of indwelling needles, dressings are needed to fix and protect the indwelling venous needle. However, the needle handle of indwelling needles is usually hard, and the dressing presses the needle handle tightly against the patient's skin, which can easily cause pressure sores on the patient's skin. This is especially true for children, the elderly, and malnourished patients, whose skin is more easily injured by the needle handle.

[0003] Therefore, a technical solution is needed to address the problem that the needle handle can easily cause pressure sores on the patient's skin when the patch is applied to fix the indwelling needle and its handle. Utility Model Content

[0004] The purpose of this invention is to overcome the technical problem in the prior art that when applying a dressing to fix an indwelling needle and its handle, the needle handle can easily cause pressure injury to the patient's skin, and to provide an indwelling needle fixation dressing.

[0005] This utility model provides an indwelling needle fixation dressing, including a patch, a first dressing block and a second dressing block on one side of the patch, the second dressing block being arranged around the first dressing block, the second dressing block being an elastic material structural component, and a notch on one side of the second dressing block.

[0006] This utility model relates to a fixation dressing for indwelling needles. In use, the first dressing block on one side of the patch is aligned with the puncture part of the indwelling needle. The needle handle of the indwelling needle is secured in the notch of the second dressing block. The patch is then pasted onto the patient's body. The second dressing block elevates the patch, preventing it from pressing on the needle handle. The object of compression is changed from the original needle handle to the elastic second dressing block, thus avoiding pressure injury to the patient's skin caused by the hard needle handle.

[0007] Preferably, the first dressing block is a hydrocolloid structural component.

[0008] Hydrocolloids are semi-occlusive dressings made of absorbent materials such as gelatin, pectin, and sodium carboxymethyl cellulose. In medical dressings, they absorb exudate, maintain a moist environment, absorb tissue exudate or small amounts of blood at the puncture site, prevent the accumulation of fluid and bacterial growth, create a moist healing environment, reduce scab formation and secondary damage during dressing changes, and have low allergenicity, making them suitable for patients with sensitive skin, such as children, the elderly, or those with fragile skin.

[0009] Preferably, the second dressing block is a foam material structural component.

[0010] The second dressing block, made of foam material, has good softness and can distribute local pressure on the skin, reducing the risk of pressure sores or mechanical damage.

[0011] Preferably, the patch is a transparent structural component.

[0012] It allows medical staff to easily observe the puncture site through the patch.

[0013] Preferably, the patch is a polyurethane film structural component.

[0014] Polyurethane film not only has good transparency, but is also breathable but waterproof, and can block liquids and bacteria.

[0015] Preferably, the patch is rectangular, and the corners of the patch are rounded.

[0016] The rectangular patch is easy to use, has a large coverage area, and the rounded corners can prevent scratches to patients or medical staff during use.

[0017] Preferably, the edge of the patch is provided with a plurality of adhesive strips.

[0018] The adhesive strip can be used to fix the needle tube between the needle handle and the positive pressure connector of the indwelling needle, preventing the needle tube from becoming tangled. At the same time, the adhesive strip can also fix the patch to the patient's body, strengthening the connection between the patch and the patient and preventing the patch from peeling off or falling off.

[0019] Preferably, the surface of the adhesive strip is covered with an oil paper layer.

[0020] When the adhesive strip is not in use, the oil paper layer can protect the adhesive strip and prevent it from becoming contaminated and losing its adhesiveness.

[0021] Preferably, a limiting seat is provided on the side of the patch away from the first dressing block. The limiting seat is a structural component made of elastic material and has a groove on it that matches the shape of the positive pressure connector of the indwelling needle.

[0022] The positive pressure connector of the indwelling needle is fixed at the top of the patch by a limiting seat, which facilitates the disassembly and connection of the positive pressure connector to the infusion tubing, and also prevents the positive pressure connector from falling to other positions and causing skin injury to the patient or causing the infusion tubing to become tangled.

[0023] Preferably, one side of the limiting seat is provided with a retaining slot for the insertion of a needle tube, and the retaining slot communicates with the groove.

[0024] This makes it easier for the positive pressure connector to snap into the groove, and also makes the positive pressure connector more stable in the groove, making it less likely to fall off.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a fixation dressing for indwelling needle tubes. By setting a second dressing block for padding the inner side of the dressing, the object of the dressing for pressing the dressing is changed from the original indwelling needle handle to the second dressing block made of elastic material, thereby avoiding pressure injury to the patient's skin caused by the hard needle handle.
