Abstract
Description
A push needle dressing for postoperative hemostasis TECHNICAL FIELD
[0001] The present application relates to a push needle dressing for postoperative hemostasis, belonging to the technical field of medical supplies. BACKGROUND
[0002] In the medical field, the treatment of postoperative wound bleeding is crucial. Traditional hemostatic dressings are usually made of gauze, cotton balls or other water-absorbing materials, which achieve hemostasis by pressing the wound or absorbing blood.
[0003] For example, a hemostatic patch is provided with hemostatic cotton, pressure regulating device and pull ring on the body, which can be adhered to the skin when hemostasis is performed on the patient's bleeding point.
[0004] However, the existing hemostatic dressings have the following defects:
[0005] (1) Limited hemostatic effect: traditional hemostatic dressings have certain limitations in hemostatic speed and effect, which cannot meet the needs of patients for rapid hemostasis after surgery.
[0006] (2) Easy to fall off or shift: traditional dressings are easy to fall off or shift after surgery, resulting in reduced or ineffective hemostasis, frequent replacement and re-fixing, and increased additional loss and corresponding cost.
[0007] (3) Low patient comfort: traditional dressings and hemostatic materials cause discomfort to patients, such as tightness and stuffiness, affecting the postoperative comfort and recovery of patients.
[0008] (4) Difficult wound healing: traditional dressings pasted on the wound create a stuffy and closed bad environment, and the exudation of wound tissue fluid can breed bacteria and cause infection.
[0009] (5) Dressing patch replacement is not easy: traditional dressings are difficult to remove and replace, which will tear the wound and cause secondary damage, increase patient discomfort, and is not conducive to wound healing, and has a certain negative impact on the doctor-patient relationship.
[0010] The push needle is a general term for push needle type intradermal needles, which are like thumbtacks. According to the theory of the skin in traditional Chinese medicine, the push needle can stimulate the meridians when applied to the acupoints of the limbs and abdomen, thereby treating diseases. Modern medicine has also confirmed that the push needle can continuously stimulate the nerve endings through weak and lasting effects, thereby improving the functions of the viscera, and continuously improving the functions of the nervous system, the digestive system and the endocrine system. The advantage of push needle treatment is that the push needle body is short and small, and does not penetrate into the subcutaneous tissue, so it is not easy to injure important nerves and blood vessels. The pain of the patient is also lighter than that of general acupuncture therapy, the bleeding degree is low, and there are almost no adverse events such as fainting, needle breaking and bending, and it is easier to be accepted by patients. The push needle has a long needle retention time and has the characteristics of 'needle retention waiting for qi'. Long time of point stimulation can play a role in bidirectional regulation.
[0011] Therefore, the combination of the push needle and the hemostatic dressing to design a push needle dressing will help to achieve the effect of rapid, stable and efficient hemostasis.
[0012] SUMMARY
[0013] The purpose of the present application is: in view of the defects of the existing hemostatic dressing, the present application provides a push needle dressing for postoperative hemostasis during hospitalization. The push needle dressing of the present application combines the push needle and the hemostatic material, and aims to achieve the goal of rapid, stable and efficient hemostasis.
[0014] In order to achieve the above purpose, the present application provides a push needle dressing for postoperative hemostasis, comprising a dressing body and a hollow push needle, wherein the dressing body comprises a patch layer, a medicine groove and a hemostatic medicine layer connected in sequence.
[0015] The hollow push needle comprises a needle body part and a needle tip part, the needle body part is in communication with the medicine groove, the hollow push needle passes through the hemostatic medicine layer so that the needle body part and the needle tip part are exposed from the hemostatic medicine layer, and a needle cap is further arranged on the needle tip part; the medicine groove is provided with medicine, and the hemostatic medicine layer is a self-adhesive layer provided with hemostatic medicine.
[0016] The patch layer is provided with a fixing belt for adjusting the fit.
[0017] Preferably, the hollow push needle and the medicine groove are vertically connected, and the needle body part is in communication with the middle part of the medicine groove.
[0018] Preferably, the hemostatic medicine layer contains at least one of the hemostatic medicines tranexamic acid, aminocaproic acid and phenolsulfonethimide.
[0019] Preferably, at least one of the auxiliary materials dextrin, starch paste and hydroxypropyl cellulose is added to the material for making the hemostatic medicine layer.
[0020] Preferably, the fixing belts arranged on both sides of the patch layer are adhesive tapes or bandages.
[0021] Preferably, the patch layer is made of medical adhesive tape, non-woven fabric or medical silicone material.
[0022] Preferably, the medicine in the medicine groove is an antibacterial and / or anti-inflammatory medicine.
[0023] Preferably, the medicine groove is made of a high polymer material (such as polyvinyl chloride PVC, etc.), stainless steel or aluminum.
[0024] Compared with the prior art, the present application has the following advantages:
[0025] (1) Rapid hemostasis: through the design of hemostatic medicine in the medicine layer, physical compression hemostasis and drug action hemostasis are combined, so that the dressing has good hemostatic effect, achieving the purpose of rapid hemostasis;
[0026] (2) Strong stability: through the structural design of the external fixation band and the connection of the press needle and the medicine groove of the patch, the falling or displacement of the dressing during postoperative activity is effectively avoided; this not only ensures the persistence of the hemostatic effect, but also greatly reduces the risk of wound rebleeding caused by the movement of the dressing, significantly improving the treatment effect of postoperative wound recovery of patients;
[0027] (3) Improve patient comfort: after applying the dressing, the press needle can massage the acupoints, improving the effect of treating common chronic painful diseases in orthopedics patients;
[0028] (4) Reduce bacterial infection at the wound site: the design of the hollow press needle connected with the medicine groove allows the antibacterial medicine to enter the patient's body smoothly; reduces the risk of bacterial infection at the wound site, and helps to promote wound healing;
[0029] (5) Improve treatment effect and patient compliance: when removing the dressing, compared with traditional products, the present application is easier to remove and will not cause secondary injury to the patient. BRIEF DESCRIPTION OF DRAWINGS
