Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a fixing dressing for an indwelling needle. Background Art

[0002] Indwelling needles, also known as intravenous indwelling needles or intravenous cannula needles, are medical supplies that are mainly used to establish venous access for long-term intravenous infusion, blood transfusion, nutritional support or blood collection and other medical operations. Indwelling needles are designed to be left in the patient's veins for a long time, reducing the pain and vascular damage caused by repeated punctures.

[0003] In order to improve the fixation effect of the indwelling needle, it is usually necessary to set a fixed dressing above the indwelling needle to fully fix the indwelling needle. Most of the existing fixed dressings are whole-piece dressings, which have the following problems when fixing the indwelling needle: 1. It is difficult to completely wrap the indwelling needle body, resulting in the tail of the indwelling needle being exposed; 2. Due to the large volume of the tail of the indwelling needle, the dressing cannot completely fit the skin when fixing the tail of the needle, resulting in poor bonding effect; 3. When fixing the indwelling needle, the dressing will press part of the pipeline under the dressing, and the hemostatic clamp needs to be set outside the dressing; resulting in a longer distance of the pipeline pressed under the dressing, which will cause excessive blood return during blood return, and clinically, coagulation after blood return often occurs. Utility Model Content

[0004] The purpose of the utility model is to overcome the above problems and provide a fixation dressing for an indwelling needle. To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An indwelling needle fixing dressing comprises a dressing body, the bottom of which is coated with glue and provided with a release layer;

[0006] One side of the patch body is provided with two openings arranged opposite to each other, and the two openings divide the patch body into a base fixing portion and an indwelling needle tail fixing portion;

[0007] The opening position adopts an easy-tear line structure design, that is, there are through holes and connecting parts arranged at intervals between the base fixing part and the indwelling needle tail fixing part at the opening.

[0008] As an improvement, the true tail fixing portion of the indwelling needle has a trapezoidal structure.

[0009] As an improvement, the release layer includes a first sheet layer and a second sheet layer, and the first sheet layer and the second sheet layer are arranged opposite to each other.

[0010] As an improvement, an extension portion is provided at one end of the needle tail fixing portion of the indwelling needle, and the extension portion covers the opening and extends to above the base fixing portion on the opposite side of the opening;

[0011] An adhesive strip is provided at the bottom of the extension part, and is fixedly connected to the base fixing part through the adhesive strip.

[0012] The advantages of the utility model are:

[0013] 1. The utility model is provided with a trapezoidal structure of the indwelling needle tail fixing part on one side of the dressing body, which can wrap the indwelling needle tail in all directions, improve the sealing of the dressing, prevent external pollution sources from contaminating the puncture position of the indwelling needle, and at the same time improve the fixing effect of the dressing on the indwelling needle.

[0014] 2. The utility model is provided with an opening for the tube to pass through. After the indwelling needle is applied and fixed, the tube can pass through the opening close to the indwelling needle. The length of the tube between the indwelling needle and the hemostatic clip is reduced, so as to avoid excessive blood return and reduce the occurrence of coagulation after blood return.
