Description
本新型係有關於一種負壓敷料所用的負壓裝置，尤其是一種便於手動產生負壓源的攜帶型負壓裝置。 The utility model relates to a negative pressure device used for a negative pressure dressing, in particular to a portable negative pressure device which is convenient for manually generating a negative pressure source.
身體傷口的自然癒合是一個由損傷時即開始作用的複雜過程。首先，身體通過使血液流向傷口，以遞送蛋白質和其他凝血物質，使傷害降至最低。血液凝塊則用以防止失血，同時細胞吞噬傷口處的細菌和殘骸。接下來，被稱為增殖期的癒合階段，身體開始修復自身，肉芽組織沉積於傷口創面。肉芽組織在傷口上提供基礎結構，細胞可從傷口的周邊向內部遷移以合圍關閉傷口。最後，隨著時間推移以形成疤痕。 The natural healing of a body wound is a complex process that begins when the injury begins. First, the body minimizes damage by allowing blood to flow to the wound to deliver protein and other blood clotting substances. Blood clots are used to prevent blood loss while the cells devour the bacteria and debris at the wound. Next, called the healing phase of the proliferative phase, the body begins to repair itself and the granulation tissue deposits on the wound surface. The granulation tissue provides a foundation on the wound, and the cells can migrate from the periphery of the wound to the inside to close the wound. Finally, over time to form scars.
習知的傷口敷料僅採用物理吸附的方式，吸出所有傷口滲出的血液及組織液，使傷口保持乾燥。然而，習知的傷口敷料並無法控制傷口周邊的環境溼度，過度乾燥的環境反而會影響傷口的癒合。 Conventional wound dressings only use physical adsorption to aspirate all blood and tissue fluid exuded from the wound to keep the wound dry. However, conventional wound dressings do not control the ambient humidity around the wound, and an excessively dry environment can affect the healing of the wound.
一種被稱作負壓傷口治療(negative pressure wound treatment,NPWT)，是可在增殖期期間，利用控制傷口溼度促進自然癒合過程的技術。負壓傷口治療是利用負壓源，例如真空泵浦，結合封口貼布、軟性吸盤與生物相容性孔隙材料，在傷口處形成負壓環境以抽取滲液，如傷口膿液及感染物質，吸引健康組織液維持潮濕的治療環境，並促進周遭血液微循環而達到加速傷口癒合的效果。負壓傷口治療利用身體的自然癒合過程，可以有效促進血液流至傷口區域，並刺激傷口上方肉芽組織的形成和健康組織的遷移。負壓傷口治療， 其通過移除從傷口滲出的帶有養分且易孳生細菌的組織液等滲液，以抑制細菌生長。 One type of negative pressure wound treatment (NPWT) is a technique that can be used to control the natural healing process during the proliferative phase by controlling wound moisture. Negative pressure wound therapy uses a negative pressure source, such as vacuum pumping, combined with a sealing patch, a soft suction cup and a biocompatible pore material to form a negative pressure environment at the wound to extract exudate, such as wound pus and infectious substances, to attract Healthy tissue fluid maintains a moist therapeutic environment and promotes peripheral blood microcirculation to achieve accelerated wound healing. Negative pressure wound treatment utilizes the body's natural healing process to effectively promote blood flow to the wound area and stimulate the formation of granulation tissue and the migration of healthy tissue above the wound. Negative pressure wound therapy, It inhibits bacterial growth by removing isotonic fluid from tissue fluid with nutrient-prone bacteria that exudes from the wound.
習知用於負壓傷口治療的負壓源之形成，一般可分為電動或手動方式，電動一般而言常採用電動真空泵浦，由於電動真空泵浦具備馬達及氣體管路構造，所以體積上較不利攜帶，且需要額外提供電源。因此，對於尚可行動但不需要長時間臥床之病患，習知採用電動真空泵浦的負壓傷口治療系統限制了病患的日常行動，更造成生活上的不便。而對於手動形成負壓源的方式，通常將空氣壓縮機構與負壓儲存區結合，以形成一手動負壓裝置，但實際吸引傷口滲液的效果來自負壓儲存區所能保存的負壓，空氣壓縮機構將負壓儲存區中的空氣擠出形成負壓，且在負壓因抽吸傷口滲液而削弱前，空氣壓縮機構並不須再次作動，故對於具備空氣壓縮機構的手動負壓裝置，病患仍需負荷空氣壓縮機構之體積與重量。 Conventionally, the formation of a negative pressure source for negative pressure wound therapy can be generally divided into electric or manual mode. Electric power is generally used for electric vacuum pumping. Since the electric vacuum pump has a motor and a gas pipeline structure, the volume is relatively high. It is unfavorable to carry and requires additional power. Therefore, for patients who are still inactive but do not need to stay in bed for a long time, it is customary to use an electric vacuum pumped negative pressure wound treatment system to limit the daily actions of patients and cause inconvenience in life. For the method of manually forming a negative pressure source, the air compression mechanism is usually combined with the negative pressure storage area to form a manual negative pressure device, but the effect of actually attracting the wound exudate comes from the negative pressure that can be saved in the negative pressure storage area. The air compression mechanism extrudes the air in the negative pressure storage area to form a negative pressure, and the air compression mechanism does not need to be operated again before the negative pressure is weakened by suctioning the wound, so the manual negative pressure with the air compression mechanism In the device, the patient still needs to load the volume and weight of the air compression mechanism.
因此，目前仍需要一種適用於負壓傷口治療系統的攜帶型負壓裝置，以進一步改善並輕量化手動負壓裝置，以增加手動負壓裝置之攜帶性與便利性。 Therefore, there is still a need for a portable negative pressure device suitable for a negative pressure wound treatment system to further improve and lighten the manual negative pressure device to increase the portability and convenience of the manual negative pressure device.
