技术领域technical field
本实用新型涉及一种创伤、修复、手术切口的医疗器具，特别是一种能满足促愈，抗感染，消炎，止痛、止血，吸水的负压式创可贴。 The utility model relates to a medical appliance for trauma, repair and surgical incision, in particular to a negative-pressure band-aid capable of promoting healing, anti-infection, anti-inflammation, relieving pain, stopping bleeding and absorbing water. the
背景技术Background technique
现临床上或家中使用的传统创可贴，仅有载药基体作用于伤口∕创面，当伤口∕创面渗夜较多时，易致创可贴黏贴边缘因浸湿而滑脱。且其结构单一，并不能完全隔绝外界环境而保持创周清洁，消炎促愈效果不佳。现代医学已认识到负压能刺激伤口∕创面毛细血管增生，增加伤口∕创面血运，刺激组织细胞快速增值，减少伤口∕创面毒素吸收，吸除组织中多余液体，降低组织间压，减轻组织水肿，从而促进伤口∕创面快速愈合。因此改进传统创可贴，研制一种新型创可贴，引入负压技术是关键。 The traditional band-aids currently used clinically or at home, only the drug-loaded matrix acts on the wound/wound surface. When the wound/wound surface seeps a lot, it is easy to cause the adhesive edge of the band-aid to slip due to wetting. And its structure is single, can not completely isolate the external environment and keep the wound week clean, and the anti-inflammatory and healing-promoting effect is not good. Modern medicine has realized that negative pressure can stimulate wound/wound capillary proliferation, increase wound/wound blood supply, stimulate rapid tissue cell proliferation, reduce wound/wound toxin absorption, absorb excess fluid in tissues, reduce interstitial pressure, and relieve tissue stress. Edema, thereby promoting rapid wound/wound healing. Therefore improving the traditional band-aid, developing a new type of band-aid, and introducing negative pressure technology is the key. the
发明内容Contents of the invention
为解决上述技术问题，本实用新型根据排出密闭容器空气同时增大其容积以产生负压的方法，提供了一种负压式创可贴。由于负压技术的引入，当其作用于伤口∕创面时，药物和负压同时启动机体创面修复，从而加速了伤口∕创面愈合。 In order to solve the above-mentioned technical problems, the utility model provides a negative-pressure band-aid according to the method of discharging the air from the airtight container while increasing its volume to generate negative pressure. Due to the introduction of negative pressure technology, when it acts on the wound/wound surface, the drug and negative pressure simultaneously start the wound repair of the body, thereby accelerating wound/wound healing. the
本实用新型是通过以下技术方案实现的： The utility model is achieved through the following technical solutions:
一种负压式创可贴，包括负压支撑罩、医用吸水敷料、载药基体、黏贴边缘、弹簧、排气孔，负压支撑罩用于封闭伤口∕创面，所述的负压支撑罩顶端由医用硬质材料构成，硬质体下端为医用软质透明薄膜，软质体下端连接于黏贴边缘，黏贴边缘上附有医用3M胶或其它对皮肤无毒无刺激医用胶。A negative pressure band-aid, comprising a negative pressure support cover, a medical absorbent dressing, a drug-loaded matrix, an adhesive edge, a spring, and an air vent. The negative pressure support cover is used to close the wound/wound surface, and the top of the negative pressure support cover Made of medical hard material, the lower end of the hard body is a medical soft transparent film, and the lower end of the soft body is connected to the adhesive edge, and the adhesive edge is attached with medical 3M glue or other non-toxic and non-irritating medical glue to the skin.
所述的弹簧由金属材料制成，弹簧呈自然长时填充于支撑罩内，上端嵌合于负压支撑罩硬质体，下穿过医用吸水辅料止于载药基体。 The said spring is made of metal material, and the spring is naturally filled in the support cover for a long time, the upper end is embedded in the hard body of the negative pressure support cover, and the bottom passes through the medical water-absorbing auxiliary material to stop at the drug-loading matrix. the
所述的医用吸水敷料位于负压支撑罩内，四周黏贴于负压支撑罩内壁，下与载药基体相连，为普通医用敷料、医用泡沫辅料或医用海绵敷料。 The medical water-absorbing dressing is located in the negative pressure support cover, and is adhered to the inner wall of the negative pressure support cover on all sides. the
所述的排气孔位于负压支撑罩硬质体上，呈漏斗状，下设有两片微朝上的弹性瓣膜，外设有能与内腔嵌合的圆台形弹性活塞。 The exhaust hole is located on the hard body of the negative pressure support cover and is in the shape of a funnel. There are two slightly upward elastic valves on the bottom, and a frustum-shaped elastic piston that can be fitted with the inner cavity on the outside. the
本实用新型由于引用了负压技术，当创可贴作用于已消毒创面时，载药基体可直接作用于伤口∕创面起到抗感染、消炎、止痛、止血、促愈作用，再当支撑罩中有负压形成时，负压作用于无炎症反应的伤口∕创面能进一步促进伤口∕创面愈合。尤其对经久不愈的慢性创面促愈作用效果更佳。 Due to the introduction of negative pressure technology in the utility model, when the band-aid acts on the sterilized wound surface, the drug-loaded matrix can directly act on the wound/wound surface to play anti-infection, anti-inflammatory, pain-relieving, hemostatic, and healing-promoting effects, and then act as a support cover with When the negative pressure is formed, the negative pressure acting on the wound/wound without inflammatory reaction can further promote the healing of the wound/wound. Especially for chronic wounds that have not healed for a long time, the effect of promoting healing is better. the

具体实施方式Detailed ways
如图1所示，负压式创可贴，包括负压支撑罩硬质体1、排气孔2、弹簧3、负压支撑罩软质体4、吸水敷料5、载药基体6、黏贴边缘7，硬质体位于负压支撑罩的顶端，硬质体外设有一上大下小的漏斗状排气孔，下设有两片微朝上的弹性瓣膜8，控制负压罩内气体只出不进，另固定一比排气孔内径略大的圆台形活塞9，活塞用于紧密封闭排气孔，硬质体内嵌合于弹簧的一端，弹簧呈自然长时填充于支撑罩内，下端穿过医用吸水敷料，另一端连接固定于带孔载药基体，支撑罩硬质体下四周通过软质透明薄膜与黏贴边缘连接。伤口∕创面经消毒清创，周边正常皮肤用酒精擦拭以清洁皮肤处理后，将负压式创可贴黏贴边缘贴于伤口∕创面正常皮肤，同时打开排气孔弹性活塞，按压硬质体使弹簧压缩，排出支撑罩内空气，支撑罩内空气通过弹性瓣膜向外排出，此时支撑罩腔内空间变小，弹性瓣膜回缩暂时封闭负压罩内腔，再用弹性活塞牢牢塞住漏斗状排气孔以密闭负压罩。压缩后的弹簧向两端产生弹力，在向下的弹力作用下，载药基体紧贴于伤口∕创面；在向上的弹力作用下，支撑罩恢复原来形状，从而使腔内体积又变大，空气变稀薄而产生负压。若伤口∕创面有渗液，液体可通过载药基体孔隙进入吸水敷料，从而避免渗液残留于创面，引发创面感染,炎症加重，起到伤口∕创面引流作用。药疗、负压、引流三管齐下，相辅相成，从而促进伤口∕创面快速愈合。 As shown in Figure 1, the negative pressure band-aid includes the hard body of the negative pressure support cover 1, the vent hole 2, the spring 3, the soft body of the negative pressure support cover 4, the absorbent dressing 5, the drug-loaded matrix 6, and the adhesive edge 7. The hard body is located on the top of the negative pressure support cover. The hard body is provided with a funnel-shaped vent hole with a large upper part and a smaller lower part. There are two elastic valves 8 facing slightly upward at the bottom to control the gas in the negative pressure cover to only go out. If not, fix a frustum-shaped piston 9 that is slightly larger than the inner diameter of the exhaust hole. The piston is used to tightly seal the exhaust hole. The hard body is embedded in one end of the spring, and the spring is naturally filled in the support cover for a long time. The lower end passes through the medical water-absorbing dressing, the other end is connected and fixed to the drug-carrying substrate with holes, and the lower and four sides of the hard body of the support cover are connected to the adhesive edge through a soft transparent film. The wound/wound is disinfected and debrided, and the surrounding normal skin is wiped with alcohol to clean the skin. After the treatment, the negative pressure band-aid adhesive edge is attached to the normal skin of the wound/wound. At the same time, the elastic piston of the vent hole is opened, and the hard body is pressed to make the spring Compress and discharge the air in the support cover, and the air in the support cover is discharged outward through the elastic valve. At this time, the space in the cavity of the support cover becomes smaller, and the elastic valve retracts to temporarily close the inner cavity of the negative pressure cover, and then firmly plug the funnel with the elastic piston Shaped exhaust holes to seal the negative pressure cover. The compressed spring generates elastic force toward both ends, and under the action of the downward elastic force, the drug-loaded matrix is closely attached to the wound/wound surface; under the action of the upward elastic force, the support cover returns to its original shape, thereby increasing the volume of the cavity. The air becomes thinner creating negative pressure. If the wound/wound has exudate, the liquid can enter the absorbent dressing through the pores of the drug-loaded matrix, thereby preventing the exudate from remaining on the wound, causing wound infection, aggravating inflammation, and playing the role of wound/wound drainage. The three-pronged approach of medication, negative pressure, and drainage complements each other to promote the rapid healing of wounds/wounds. the
