本創作係關於一種負壓治療水凝膠貼片，特別係指一種用於減壓治療系統上水凝膠貼片，及一種提供該減壓治療系一方便替換使用且可維持負壓的接頭裝置及一種能夠保持創傷傷口癒合適當環境、縮短癒合時間、抗菌病並減少感染機會。The present invention relates to a negative pressure therapeutic hydrogel patch, in particular to a hydrogel patch for use in a reduced pressure treatment system, and a connector for providing a convenient replacement and maintaining a negative pressure. The device and an environment that maintains the wound wound healing, shortens healing time, antibacterial disease, and reduces infection.
隨著醫療科技的提昇，已發展出各種促進傷口治療或癒合之療法。其中臨床研究發現，於傷口組織部位提供減壓環境可加速該傷口組織部位之新組織之生長，因此透過減壓方式用於創傷治療之技術，被稱作「負壓組織治療」、「負壓組織治療(Negative Pressure Wound Therapy)」、「減壓治療」或「真空療法」等，此類治療提供許多效益，包括癒合更快及肉芽組織之形成增加。With the advancement of medical technology, various therapies that promote wound healing or healing have been developed. Among them, clinical studies have found that providing a decompression environment at the wound tissue site can accelerate the growth of new tissue in the wound tissue site. Therefore, the technique for trauma treatment by decompression is called "negative pressure tissue therapy" and "negative pressure." Such treatments (Negative Pressure Wound Therapy), "decompression therapy" or "vacuum therapy" provide many benefits, including faster healing and increased formation of granulation tissue.
外科手術因為治療的需求以及內窺鏡手術的風行，已經大幅降低因為手術所造成的風險，但是隨之而來的卻是對於更好的傷口照護以及術後疤痕預防的需求，目前已經出現借助各種先進敷料進行傷口照護的方法，藉以縮短傷口癒合時間同時消除疤痕。Surgery because of the need for treatment and the popularity of endoscopic surgery, has greatly reduced the risk of surgery, but it is followed by the need for better wound care and post-surgical scar prevention. A variety of advanced dressings for wound care to shorten wound healing time while eliminating scarring.
傳統的敷料是由天然植物纖維或動物毛類物質構成，如紗布、棉墊、羊毛、各類油紗布等，這類敷料只是暫時性的覆蓋材料，均需 在一定的時間內加以更換。現有創傷敷料的研究讓人們對於創傷敷料的認識日趨科學，研究表明：較佳的創傷敷料能夠保持創傷處的良好細胞生長癒合環境，能夠控制和吸收滲出物；透氣、透濕，能阻止細菌侵入；能緊密貼敷於創傷面；可載設、釋放藥物；另外應具有良好的組織及血液相容性，在從創傷面揭取時不發生粘連和脫屑；還應當具有較佳的機械性能和抗拉強度，使用方便。Traditional dressings are made up of natural plant fibers or animal hairs, such as gauze, cotton pads, wool, various types of oil gauze, etc. These dressings are only temporary covering materials, all of which are required. Replace it within a certain period of time. The research on existing wound dressings has made people's understanding of wound dressings more and more scientific. Studies have shown that better wound dressings can maintain a good cell growth healing environment at the wound site, can control and absorb exudates; breathable, moisture permeable, can prevent bacterial invasion It can be applied to the wound surface tightly; it can be loaded and released; it should have good tissue and blood compatibility, no adhesion and desquamation when it is removed from the wound surface; it should also have better mechanical properties. And tensile strength, easy to use.
是以，對於目前覆蓋傷口之敷件，因其特殊設計，造成不容易替換使用，故如何提高減壓治療系統的及更好治療及傷口癒合之效果，是目前仍待解決之問題。Therefore, for the current dress covering the wound, due to its special design, it is not easy to replace, so how to improve the effect of the decompression treatment system and better treatment and wound healing is still a problem to be solved.

關於本創作其用於傷口、蚊蟲貼、瘡痍或疤痕。About this creation it is used for wounds, mosquito stickers, sores or scars.
關於本創作所述之可置換式水凝膠貼片，該可置換式水凝膠 貼片為一方型、圓形或不規則形狀之貼片。Regarding the replaceable hydrogel patch of the present invention, the replaceable hydrogel The patch is a patch of one-piece, round or irregular shape.
關於本創作所述之負壓吸引器裝置，其中該裝置係為以製作負壓原理製作以用於吸附之裝置。於一較佳的實施例中，其中該負壓吸引器裝置包含一吸盤本體及管柱接頭，該管柱接頭與該吸盤本體相連接。With respect to the vacuum suction device of the present invention, the device is a device fabricated for the purpose of suction by the principle of making a vacuum. In a preferred embodiment, the vacuum suction device comprises a suction cup body and a pipe joint, and the pipe joint is connected to the suction cup body.
關於本創作所述之負壓吸引器裝置，其材質包含但不限於軟性或硬性之材質，如矽膠、強化塑膠、樹脂、天然橡膠或合成橡膠。於較佳之實施例中，該負壓吸引器的材質係指矽膠。The material of the negative pressure aspirator device described in the present invention includes, but is not limited to, a soft or rigid material such as silicone rubber, reinforced plastic, resin, natural rubber or synthetic rubber. In a preferred embodiment, the material of the vacuum suction device is silicone.
關於本創作所述之負壓吸引器裝置，其中該吸盤本體與管柱接頭可為一體成型之結構。With respect to the vacuum suction device of the present invention, the suction cup body and the column joint may be integrally formed.
關於本創作之水凝膠貼片包含(a)一聚氨酯膜層，其為單一方向滲透膜；(b)一感壓膠層，其為疏水性材質，塗佈於聚氨酯膜層，使其與皮膚貼合；(c)熔噴型不織布，其具多向彈性張力；及水凝膠，其為親水性材質；其中熔噴型不織布及水凝膠係經紫外光照射貼合為網狀交錯聚合物，該熔噴型不織布部分纖維外露與感壓膠層穩定貼合，並賦予水凝膠多向彈性以適應不同皮膚部位。The hydrogel patch of the present invention comprises (a) a polyurethane film layer which is a single direction permeable film; (b) a pressure sensitive adhesive layer which is a hydrophobic material and is applied to the polyurethane film layer to make it (c) melt-blown non-woven fabric with multi-directional elastic tension; and hydrogel, which is a hydrophilic material; wherein the melt-blown non-woven fabric and hydrogel are laminated by ultraviolet light to form a network interlaced The polymer, the melt-blown non-woven part of the fiber exposed and the pressure sensitive adhesive layer is stably adhered, and gives the hydrogel multi-directional elasticity to adapt to different skin parts.
本創作水凝膠結構中的水凝膠作為接觸創傷傷口的貼合面，該水凝膠能夠使創傷傷口處於該加速癒合的適當濕度狀態。濕性癒合環境有利於傷口癒合，如果傷口脫水，細胞則不能存活，雖然各種濕潤的紗布或繃帶也能提供濕性的癒合環境，但是由於該紗布或繃帶類敷料需要經常更換而導致新形成的細胞易於損傷，造成傷口二次傷害，且有脫水的危險。本創作水凝膠結構中的水凝膠具吸水退黏特性，在換藥時比起一般濕潤的紗布或繃帶例如凡士林紗布，對傷口的破壞較少，其吸水倍率更加 符合傷口癒合所需求的最佳濕潤狀態，吸收多餘水分，保持皮膚適當濕度，且更具載藥性。The hydrogel in the present hydrogel structure acts as a conforming surface for contacting the wound wound, which enables the wound wound to be in the proper humidity state for accelerated healing. The wet healing environment is conducive to wound healing. If the wound is dehydrated, the cells cannot survive. Although various wet gauze or bandages can provide a moist healing environment, the gauze or bandage dressing needs to be replaced frequently to cause a new formation. The cells are prone to damage, causing secondary damage to the wound and the risk of dehydration. The hydrogel in the hydrogel structure of the present invention has a water-absorbing and detacking property, and the damage to the wound is less than that of a generally wet gauze or a bandage such as Vaseline gauze, and the water absorption ratio is more It meets the optimal moist state required for wound healing, absorbs excess moisture, maintains proper skin moisture, and is more drug-loaded.
