Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to a catheter fixation device suitable for use on broken skin. Background Technology

[0002] An indwelling intravenous catheter, also known as a venous cannula, consists primarily of a flexible catheter / cannula that can be left in a blood vessel and a stainless steel guide needle. During use, the catheter and guide needle are inserted together into the blood vessel. Once the catheter is fully inside the vessel, the guide needle is withdrawn, leaving only the flexible catheter in place for intravenous infusion. Indwelling intravenous catheters are a preferred method for clinical intravenous infusion, reducing the pain of repeated punctures for patients and decreasing the workload of clinical nurses. While ordinary dressings are typically used to secure indwelling catheters, they lack breathability and do not provide skin protection. Meanwhile, for dermatology patients, whose skin may already have skin conditions, the regular changing of the dressing can cause the cannula to come off due to the direct adhesion to the patient's skin, thus aggravating the skin lesions. This not only causes the patient some pain but may also aggravate or induce skin damage and allergies. In addition, the dressing can be contaminated by exudate from the original skin lesion site, and the skin covered by the dressing cannot be used for medication. Therefore, ensuring sterility at the puncture site while allowing medication to be applied to the lesion is crucial.

[0003] The prior art, disclosed in CN213252028U, is a comfortable and reinforced intravenous indwelling needle patch. It achieves comfort and breathability and is easy to remove by setting multiple ventilation holes in the patch side area. However, it still has the problem of easily causing skin tears and is not suitable for use by dermatology patients. Utility Model Content

[0004] 1. The technical problem to be solved: To address the aforementioned technical problems, this utility model provides a catheter fixation device suitable for use on broken skin. It avoids direct contact between sticky adhesive tape and the skin, preventing aggravation or induced skin damage and allergies. Furthermore, the petroleum jelly gauze dressing is more breathable than traditional films, absorbing exudate from the broken skin, facilitating easy replacement, and promoting tissue repair. It allows for proper fixation of the catheter on broken skin, and the puncture site can be observed at any time through the chlorhexidine observation window, preventing catheter slippage and infection. It has wide applicability.

[0005] 2. Technical Solution: A catheter fixation device suitable for use on broken skin includes a fixation patch body, characterized in that: the fixation patch body is rectangular; the fixation patch body includes a square piece of Vaseline gauze with a square through hole in the center; a square piece of transparent chlorhexidine dressing is fixedly connected to the inner surface of the through hole; a medical foam frame is provided on the outer surface of the Vaseline gauze, and the outer surface of the medical foam frame is fixedly adhered to a fixation layer; the fixation layer is a mesh elastic bandage; the outer surface of the fixation patch body is covered by the elastic bandage, and the elastic bandage has a buckle structure on both sides to close and connect the two ends; an adhesive point is provided on one side of the fixation patch body, where the Vaseline gauze, medical foam frame, and fixation layer are all fixedly connected, so that the adhesive point can serve as a flipping axis when the medical foam frame is flipped open.

[0006] Furthermore, the square petroleum jelly gauze is a single layer with a size of (11~9)cm*(7~8)cm; the square through-hole in the middle, i.e., the chlorhexidine dressing, has a size of (2.5~3.5)cm*(1.5~2.5)cm; and the fixing layer has a size of (28~32)cm*(7~9)cm. Furthermore, the medical foam frame includes two side-by-side anti-seepage rings; each anti-seepage ring is U-shaped; a transparent chlorhexidine dressing is located between the two anti-seepage rings; the hollow size of each anti-seepage ring is 3.5cm*6cm, used for applying the medication.

[0007] Furthermore, the buckle structure at both ends of the fixing layer is as follows: one end is provided with a long strip of self-adhesive, and the corresponding position of the other end is provided with a through hole for the self-adhesive. When in use, the long strip of self-adhesive is folded after passing through the through hole to achieve a ring-shaped fixation of the fixing layer.

[0008] Furthermore, the petroleum jelly gauze has an incision for inserting a needle through a vein.

[0009] Furthermore, the outer surface of the fixation layer is also provided with a fixing chain for fixing the base of the indwelling intravenous needle; the fixing chain is composed of multiple elastic rings connected in sequence, and in use, the base of the indwelling intravenous needle can pass through one of the elastic rings of the fixing chain to achieve fixation of the indwelling intravenous needle.

[0010] 3. Beneficial effects: This invention provides a catheter fixation device suitable for use on broken skin. The main body of the transparent dressing consists of a chlorhexidine dressing layer in the middle, which accelerates inflammation absorption and also has antibacterial and cross-infection prevention properties. The lower surface of the dressing body is covered with petrolatum gauze, which provides skin protection, prevents adhesion to wounds, promotes wound healing, and prevents infection. Therefore, it can prolong the indwelling time of the intravenous catheter, thereby protecting the patient's blood vessels, reducing the pain and financial burden of repeated punctures, and reducing medical accidents such as bleeding at the catheter insertion site. Below the petrolatum gauze, two leak-proof rings are formed using a medical foam frame. Medication can be applied within these rings to accelerate the recovery of broken or wounded skin. The long side of the petrolatum gauze has an incision, and a chain-like fixing chain is located on the outer side of the fixation layer to secure the needle handle. Attached Figure Description
