Description

Technical Field

[0001] The utility model relates to a press-needle dressing and belongs to the technical field of medical supplies. Background Art

[0002] In the medical field, it is very important to deal with postoperative wound bleeding. Traditional hemostatic dressings are usually made of gauze, cotton balls or other absorbent materials, which achieve the purpose of hemostasis by compressing the wound or absorbing blood.

[0003] For example, a hemostatic patch is provided with hemostatic cotton, a pressure regulating device and a pull ring on the main body of the hemostatic patch. When the bleeding point of the patient is stopped, the main body of the hemostatic patch can be adhered to the skin.

[0004] However, existing hemostatic dressings have the following defects:

[0005] (1) Easy to fall off or shift: Traditional dressings are easy to fall off or shift after surgery, resulting in reduced or ineffective hemostatic effect. Frequent replacement and re-fixation are required, resulting in additional losses and corresponding costs.

[0006] (2) The wound is difficult to heal and the pain persists, causing suffering to the patient: Traditional dressings adhered to the wound will create a hot, stuffy and closed environment at the wound. The exudation of tissue fluid at the wound will breed bacteria and cause infection. In addition, the persistent pain caused by the wound increases the patient's suffering.

[0007] Pressing needles are a general term for press-needle intradermal needles, which are in the shape of thumbtacks. According to the skin theory of traditional Chinese medicine, pressing needles applied to the acupuncture points of the limbs and abdomen can stimulate the meridians and treat diseases. Modern medicine has also experimentally confirmed that pressing needles can continuously stimulate nerve endings through weak and lasting therapeutic effects, thereby improving the function of internal organs, and can sustainably improve the functions of the nervous system, digestive system, endocrine system, etc. The advantage of pressing needle treatment is that the needle body of the pressing needle is relatively short and will not penetrate too deep into the subcutaneous tissue, and it is not easy to injure important nerves and blood vessels. The patient's pain level is also lighter than that of general acupuncture therapy, and the degree of bleeding is low. There are almost no problems such as fainting, broken needles, and bent needles, which are more easily accepted by patients. Pressing needles have a long retention time and have the characteristics of "retaining the needle and waiting for the qi". Long-term acupoint stimulation can play a role in bidirectional regulation.

[0008] At present, there are no reports on press-pin dressings that combine press-pins with hemostatic dressings. Summary of the invention

[0009] The purpose of the utility model is: to address the defects of existing hemostatic dressings such as easy infection, falling off or displacement, the utility model provides a press-pin dressing. The press-pin dressing of the utility model combines the press-pin and the hemostatic dressing into one, which can solve the shortcomings of the hemostatic dressings such as poor hemostatic effect, easy infection, falling off or displacement, and can also relieve the pain of patients.

[0010] In order to achieve the above-mentioned purpose, the utility model provides a press needle dressing, comprising a dressing body and a hollow press needle, wherein the dressing body comprises a patch layer, a drug groove and a hemostatic drug layer connected in sequence;

[0011] The hollow press needle includes a needle body and a needle tip, the needle body is connected to the medicine groove, the hollow press needle passes through the hemostatic medicine layer so that its needle body and needle tip are exposed from the hemostatic medicine layer, and a needle cap is also provided on the needle tip; the hemostatic medicine layer is a self-adhesive layer provided with hemostatic medicine.

[0012] Preferably, the hollow press needle is vertically connected to the medicine groove, and the needle body is connected to the middle of the medicine groove.

[0013] Preferably, the patch layer is a non-adhesive patch layer, and fixing belts for adjusting the fit are provided on both sides of the patch layer.

[0014] Preferably, the fixing tape is an adhesive tape or a binding tape.

[0015] Preferably, the patch layer is made of medical adhesive tape, non-woven fabric or medical silicone material.

[0016] Preferably, antibacterial and / or anti-inflammatory drugs are provided in the drug groove.

[0017] Preferably, the drug tank is made of a polymer material (such as polyvinyl chloride (PVC), etc.), stainless steel or aluminum.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] (1) Strong stability: The design of an external fixing strap and a push pin connected to the patch drug slot effectively prevents the dressing from falling off or shifting during postoperative activities. This not only ensures the durability of the hemostatic effect, but also greatly reduces the risk of wound re-bleeding caused by dressing movement, significantly improving the therapeutic effect of postoperative wound recovery;

[0020] (2) Improve the patient's pain relief and reduce bacterial infection at the wound: After the dressing is applied, the press needles can stimulate the meridian points, which can improve the patient's treatment effect in common chronic painful diseases in orthopedics; the design of connecting the hollow press needles with the drug slot allows antibacterial drugs to enter the patient's body smoothly; it reduces the risk of bacterial infection at the wound and helps promote wound healing.
