[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figures 1 to 4 As shown, an antibacterial hemostatic dressing for easy fixation of an indwelling needle includes:

[0029] Apply outer layer 1;

[0030] Fixing mechanisms 2 are installed on both sides of the top of the outer layer 1, and a reinforcing adhesive layer 6 is coated on the bottom of the outer layer 1.

[0031] The fixing mechanism 2 includes a pressure-reducing pad 21, an adhesive layer 22, a fixing band 23, and a release strip 24. The adhesive layer 22 is installed at the bottom end of the pressure-reducing pad 21, and the pressure-reducing pad 21 is attached to the top end of the outer layer 1 through the adhesive layer 22. There are two fixing bands 23 and two release strips 24. The two fixing bands 23 are installed at the top end of the pressure-reducing pad 21, and the two release strips 24 are installed at the bottom end of the two fixing bands 23 respectively.

[0032] Depend on Figure 1 , Figure 2 and Figure 4It can be seen that a relief groove 7 is provided on one side of the bottom of the outer layer 1 and the bottom of the reinforcing adhesive layer 6. A release sheet 3 is installed on one side of the fixing mechanism 2 near the bottom of the relief groove 7. Easy-tear tabs 4 are provided at the four corners of the outer surface of the outer layer 1. An information label 5 is installed at the top center of the outer layer 1.

[0033] As described above, when the indwelling needle is inserted into the patient's vein, first, pinch the easy-tear strip 4 to remove the entire dressing from the release paper. Then, align the needle hole dressing 9 with the indwelling needle and insert it into the needle hole. Through the reinforcing adhesive layer 6, the outer layer 1 of the dressing can be firmly adhered to the patient's skin, and the handle of the indwelling needle is positioned in the relief groove 7. The handle of the indwelling needle can then be passed through the relief groove 7 and positioned above the pressure relief pad 21. At this point, it can be peeled off from the fixing mechanism 2 through the protrusion on the release strip 3, allowing the adhesive layer 22 on the pressure relief pad 21 to adhere to the outer layer 1 of the dressing. The outer layer 1 of the dressing, separated by the relief groove 7, is secured on both sides. Then, the release strip 24 is peeled off from the fixing band 23 by the protrusion on the release strip 24, so that the two fixing bands 23 are attached to the handle of the indwelling needle in an X-shape on the pressure relief pad 21. The Y-shaped interface of the indwelling needle is then fixed to another fixing mechanism 2 in the same way. This design ensures the firmness of the adhesion and avoids excessive pressure on the patient's skin, thereby greatly reducing the pressure on the patient's skin, improving the patient's comfort, avoiding pressure injury, and reducing the risk of its occurrence.

[0034] For details, please refer to Figure 1 , Figure 2 and Figure 4 As shown, the pressure relief pad 21 is made of rubber sponge, the bottom end of the fixing band 23 is adhesive, and both the release strip 24 and the release sheet 3 are provided with protrusions. The outer layer 1 is made of transparent waterproof material.

[0035] As can be seen from the above, the pressure relief pad 21 provides comfortable support and pressure relief, preventing pressure sores or discomfort caused by prolonged pressure on the skin. The fixing strap 23 can firmly attach the indwelling needle to the pressure relief pad 21. The raised design makes it easier for users to hold and operate when tearing off the release strip 24 or release sheet 3, and also increases the convenience of tearing off. The transparent material makes it easy to observe the condition inside the dressing, such as whether there is bleeding or seepage.

[0036] Example 2:

[0037] refer to Figure 2 and Figure 3 As shown, a composite dressing 8 is installed at the bottom end of the reinforcing adhesive layer 6, and a pinhole dressing 9 is installed at the middle of the bottom end of the reinforcing adhesive layer 6.

[0038] The composite dressing 8 includes an antibacterial dressing layer 81, a hemostatic dressing layer 82, and clearance notches 83. The antibacterial dressing layer 81 is installed at the bottom end of the reinforcing adhesive layer 6, the hemostatic dressing layer 82 is installed at the bottom end of the antibacterial dressing layer 81, and two clearance notches 83 are provided, which are respectively opened at the bottom end of the antibacterial dressing layer 81 and the bottom end of the hemostatic dressing layer 82.

[0039] As can be seen from the above, during the use of this dressing, the transparent outer layer 1 allows medical staff to clearly observe the condition of the indwelling needle and the surrounding skin, which helps to promptly detect and treat abnormalities such as redness, swelling, and exudation. The information label 5 can record information such as the insertion time of the indwelling needle and the patient's name. At the same time, the needle hole dressing 9 covering the needle hole can absorb the blood and water seeping from the needle hole and effectively stop bleeding, preventing blood and water accumulation from causing infection. It can also keep the wound clean and dry and promote wound healing. In addition, the avoidance notch 83 in the composite dressing 8 cleverly avoids the indwelling needle, while the annular antibacterial dressing layer 81 and the hemostatic dressing layer 82 tightly cover the indwelling needle, forming a protective layer that effectively prevents bacterial invasion. In particular, the antibacterial dressing layer 81 can effectively inhibit bacterial growth and further reduce the risk of infection.

[0040] Preferred, Reference Figure 2 and Figure 3 As shown, both the antibacterial dressing layer 81 and the hemostatic dressing layer 82 are designed as annular structures, the clearance notch 83 is located directly below the clearance groove 7, and the material of the pinhole dressing 9 is the same as that of the composite dressing 8.

[0041] As can be seen from the above, the ring structure allows the composite dressing 8 to fit around the indwelling needle, providing effective antibacterial and hemostatic protection without affecting the normal use of the indwelling needle. The design of the avoidance notch 83 allows the composite dressing 8 to avoid the indwelling needle. The consistent material ensures that the needle hole dressing 9 and the composite dressing 8 are consistent in performance, ensuring that the wound area is fully protected and cared for.

[0042] Application example:

[0043] This design is primarily intended for use in medical settings, particularly for patients requiring long-term or frequent intravenous infusions. These patients often need continuous intravenous therapy for a period of time due to their illness or treatment needs. The use of indwelling needles aims to reduce the pain caused by repeated punctures and lower the risk of infection. Specific application scenarios include, but are not limited to, hospital wards, emergency departments, and operating rooms. This design significantly improves the adhesion of the outer dressing layer 1 by incorporating a reinforcing adhesive layer 6 and a fixing mechanism 2. The reinforcing adhesive layer 6 not only firmly adheres the indwelling needle to the patient's skin but also effectively prevents the indwelling needle from shifting. The fixation mechanism 2 reduces pressure on the patient's skin when fixing the indwelling needle, thereby enhancing the fixation effect and improving patient comfort. In addition, this design also includes a composite dressing 8 with multiple functions such as antibacterial, hemostatic, and moisture-absorbing properties. This dressing can tightly cover the indwelling needle to form an effective protective layer, preventing bacterial invasion and significantly reducing the risk of infection. At the same time, the tight fit of the needle hole dressing 9 forms an effective seal at the needle hole of the indwelling needle, preventing blood or medication leakage and keeping the area around the needle hole clean and dry.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
