Abstract
Description
本發明是有關於一種排流設備(drainage equipment)，且特別是有關於一種傷口排流設備(wound drainage equipment)，應用於其之連接管件、連接頭與傷口覆蓋件。 This invention relates to a drainage apparatus, and more particularly to a wound drainage apparatus to which a connecting tube, a connector and a wound cover are applied.
真空傷口癒合治療(vacuum assisted closure therapy)，或負壓傷口治療(negative pressure wound therapy)，為輔助性物理療法的一種。此治療之方式是利用負壓幫浦(negative pressure pump)結合封口貼片(sealing sheet)或傷口覆蓋件(wound cover)，並採用具生物相容性的多孔網篩(porous screen)作為敷料，以在傷口內形成負壓環境。外加負壓使得多孔網篩體積縮小，間接造成傷口向中緊縮，並且藉由多孔網篩牽引邊界細胞，促進細胞分裂增生，加速傷口癒合。負壓經多孔網篩在傷口內傳遞，除吸引細胞間組織液(tissue fluid)流動，間接促進血管增生與局部血液循環外，還可將傷口內的細菌膿血及過多的組織液抽出，以避免水腫、減少發炎的機會、提供具有適當濕度的癒合環境、並保護傷口，進而減少傷口癒合所需要的時間。 Vacuum assisted closure therapy, or negative pressure wound therapy, is a type of assistive physical therapy. The treatment is performed by using a negative pressure pump in combination with a sealing sheet or a wound cover, and using a biocompatible porous screen as a dressing. To create a negative pressure environment within the wound. The addition of negative pressure causes the volume of the porous mesh to shrink, indirectly causing the wound to contract inward, and the boundary cells are pulled by the porous mesh sieve to promote cell division and proliferation and accelerate wound healing. Negative pressure is transmitted through the porous mesh screen in the wound. In addition to attracting the flow of tissue fluid, indirectly promoting vascular proliferation and local blood circulation, bacteria pus and excessive tissue fluid can be extracted from the wound to avoid edema. Reduce the chance of inflammation, provide a healing environment with proper humidity, and protect the wound, thus reducing the time required for wound healing.
請參考圖1，其繪示習知之一種傷口排流設備的示意圖。習知之傷口排流設備100包括一傷口覆蓋件110、一抽吸裝置(suction appliance)120、一連接管件(conduit)130與一多孔網篩140。多孔網篩 140配置於一傷口10，傷口覆蓋件110配置於多孔網篩140與傷口10上。抽吸裝置120具有一收集容器(collecting container)122與一負壓幫浦(未繪示)。連接管件130連通(communicate)傷口10與抽吸裝置120的收集容器122。當傷口排流設備100運作時，負壓幫浦提供負壓，使得將傷口10內之滲出液(exudates)藉由連接管件130被抽出至收集容器122內。 Please refer to FIG. 1 , which illustrates a schematic diagram of a conventional wound drainage device. The conventional wound drainage device 100 includes a wound cover 110, a suction appliance 120, a connecting tubing 130, and a perforated mesh screen 140. Porous mesh screen The 140 is disposed on a wound 10, and the wound cover 110 is disposed on the porous mesh screen 140 and the wound 10. The suction device 120 has a collecting container 122 and a negative pressure pump (not shown). The connecting tube 130 communicates the wound 10 with the collection container 122 of the suction device 120. When the wound drainage device 100 is in operation, the negative pressure pump provides a negative pressure such that exudates within the wound 10 are drawn into the collection container 122 by the connecting tube 130.
然而，此習知傷口排流設備100在運作一段時間後，由於傷口覆蓋件110與傷口10之間形成近似密封狀態，且內部壓力將愈來愈低，所以傷口10內的滲出液的抽吸將愈形不易，使得傷口10內的滲出液的抽吸的效率降低。因此，習知傷口排流設備100實有改進之必要。 However, after the operation of the conventional wound drainage device 100 for a period of time, the suction of the exudate in the wound 10 is caused by the formation of an approximately sealed state between the wound cover 110 and the wound 10, and the internal pressure will be lower and lower. The resulting shape will be less prone to reduce the efficiency of the pumping of the exudate within the wound 10. Therefore, the conventional wound drainage device 100 is necessary for improvement.

通氣孔H1配置於傷口排流組件A1的連接管件230上，且通氣孔H1連通通孔232與一外界環境。詳言之，本實施例之通氣孔H1由連接管件230之一壁體(wall)234的一外表面(outer surface)234a延伸至壁體234的一內表面(inner surface)234b，進而連接至通孔232。本實施例中，通氣孔H1的數量示意地繪示一個，然而通氣孔H1的數量可依設計需求而為多個。 The vent hole H1 is disposed on the connecting tube 230 of the wound drainage assembly A1, and the vent hole H1 communicates with the through hole 232 and an external environment. In detail, the vent hole H1 of the present embodiment extends from an outer surface 234a of a wall 234 of the connecting tubular member 230 to an inner surface 234b of the wall 234, thereby being connected to Through hole 232. In this embodiment, the number of the vent holes H1 is schematically shown as one, but the number of the vent holes H1 may be plural according to design requirements.
當傷口排流設備200運作時，抽吸裝置220的負壓幫浦提供負壓，負壓經由收集容器222、連接管件230的通孔232與多孔網篩240而傳遞至傷口20，使得傷口20內之滲出液藉由連接管件230的通孔232沿著流向D1(亦即，離開傷口20且朝向抽吸裝置220的流向D1)而被抽出至抽吸裝置220的收集容器222內。 When the wound drainage device 200 is in operation, the negative pressure pump of the suction device 220 provides a negative pressure, and the negative pressure is transmitted to the wound 20 via the collection container 222, the through hole 232 of the connection tube 230, and the porous mesh screen 240, so that the wound 20 The exudate is drawn into the collection container 222 of the suction device 220 by the through hole 232 of the connection tube 230 along the flow direction D1 (i.e., away from the wound 20 and toward the flow direction D1 of the suction device 220).
由於通氣孔H1連通連接管件230的通孔232與外界環境，所以當抽吸裝置220提供負壓且在抽出傷口20內之滲出液時，氣流會由通 氣孔H1進入通孔232而沿著流向D1流動。因此，與習知技術相較，本實施例之傷口排流設備200運作時的連接管件230的通孔232內的流體流動性較佳，使得本實施例之傷口排流設備200對於傷口20內的滲出液的抽吸將較有效率。 Since the vent hole H1 communicates with the through hole 232 of the connecting tubular member 230 and the external environment, when the suction device 220 provides a negative pressure and the exudate in the wound 20 is withdrawn, the air flow is passed through. The air hole H1 enters the through hole 232 and flows along the flow direction D1. Therefore, compared with the prior art, the fluid flowability in the through hole 232 of the connecting tube 230 when the wound drainage device 200 of the present embodiment operates is preferred, so that the wound drainage device 200 of the present embodiment is within the wound 20 The pumping of the exudate will be more efficient.

In the present embodiment, the vent hole H3 of the wound drainage device 400 is disposed on the wound cover 410 of the wound drainage assembly A3. The wound cover 410 is a cup-shaped cover. The through hole 432 of the connecting tube 430 communicates the wound cover 410 with the collection container 422 of the suction device 420, thereby communicating the wound 40 with the collection container 422.
請參考圖5，其繪示本發明第四實施例之一種傷口排流設備的示意圖。在本實施例中，傷口排流設備600的連接管件630的一端深入傷口60，例如為紗布的多孔網篩640則填充於傷口60內。此外，例如為黏性膜的傷口覆蓋件610覆蓋多孔網篩640、部分連接管件630與傷口60。本實施例中，通氣孔H5位於連接管件630上。 Please refer to FIG. 5, which is a schematic diagram of a wound drainage device according to a fourth embodiment of the present invention.

圖6A繪示本發明第五實施例之一種傷口覆蓋件的立體示意 圖。圖6B繪示圖6A之傷口覆蓋件的俯視示意圖。圖6C繪示圖6B之傷口覆蓋件沿著線FF的剖面示意圖。圖6D繪示圖6C之傷口覆蓋件配置有管件的剖面示意圖。圖6E繪示圖6A之傷口覆蓋件配置有管件的立體示意圖。請參考圖6A至圖6E，本實施例之傷口覆蓋件710可取代第三實施例之傷口覆蓋件410而配置於傷口40(見圖4)上。本實施例之傷口覆蓋件710包括一第一連接孔712與第二連接孔713，且通氣孔H6配置於傷口覆蓋件710。第二連接孔713適於面向傷口40(見圖4)。值得注意的是，通氣孔H6僅經由傷口覆蓋件710之內部空間714而與第一連接孔712連通。過濾片(未繪示)可配置於通氣孔H6。 6A is a perspective view of a wound cover of a fifth embodiment of the present invention. Figure. 6B is a top plan view of the wound cover of FIG. 6A. 6C is a cross-sectional view of the wound cover of FIG. 6B along line FF. 6D is a cross-sectional view of the wound cover of FIG. 6C configured with a tubular member. 6E is a perspective view of the wound cover of FIG. 6A configured with a tubular member. Referring to FIGS. 6A-6E, the wound cover 710 of the present embodiment can be disposed on the wound 40 (see FIG. 4) in place of the wound cover 410 of the third embodiment. The wound cover 710 of the embodiment includes a first connecting hole 712 and a second connecting hole 713, and the vent hole H6 is disposed on the wound cover 710. The second attachment aperture 713 is adapted to face the wound 40 (see Figure 4). It is to be noted that the vent hole H6 communicates with the first connection hole 712 only via the internal space 714 of the wound cover 710. A filter (not shown) may be disposed in the vent hole H6.
連接管件730之一端適於配置於第一連接孔712，而連接管件730之另一端適於連接至抽吸裝置(未繪示)，使得第一連接孔712連通連接管件730之通孔732，進而與抽吸裝置連通。再次強調的是，通氣孔H6連通連接管件730之通孔732與外界環境。此外，通氣孔H6可選擇性地與一通氣管件750連接，使得通氣孔H6連通通氣管件750之通孔752。 One end of the connecting tube 730 is adapted to be disposed on the first connecting hole 712, and the other end of the connecting tube 730 is adapted to be connected to a suction device (not shown) such that the first connecting hole 712 communicates with the through hole 732 of the connecting tube 730, Further, it is in communication with the suction device. It is emphasized again that the vent hole H6 communicates with the through hole 732 of the connection pipe 730 and the external environment. Further, the vent hole H6 is selectively connectable to a vent tube 750 such that the vent hole H6 communicates with the through hole 752 of the vent tube 750.
在本實施例中，通氣孔H6位於第一連接孔712的下方。通氣孔H6之一開口H62的外半徑R1小於第一連接孔712之一開口712a的外半徑R2。通氣孔H6之開口H62的指向N1實質上平行於第一連接孔712之開口712a的指向N2。通氣孔H6之開口H62的指向N1實質上不平行於(在本實施例中例如為近似垂直於)第二連接孔713之一開口713a的指向N3。在此必須說明的是，所謂開口的指向意謂此開口所在平面的法線方向。通氣孔H6之開口H62的中心與第一連接孔712之開口712a的中心的距離小於或等於通氣孔H6之開口H62的外半徑R1與第一連接孔712之開口712a的外半徑R2的和。通氣孔H6之開口H62的中心與第二連接孔713之開口713a所在之一平面S1的距離小於第一連接孔712之開口712a的中心與平面S1的距離。因此，通氣孔H6與第一連接孔712可儘量地靠近，使得傷口覆蓋件710的高度T1可儘量地小，以讓使用此傷口覆蓋件710的 患者感覺較為舒適。 In the present embodiment, the vent hole H6 is located below the first connection hole 712. The outer radius R1 of one opening H62 of the vent hole H6 is smaller than the outer radius R2 of the opening 712a of one of the first connection holes 712. The direction N1 of the opening H62 of the vent hole H6 is substantially parallel to the direction N2 of the opening 712a of the first connection hole 712. The direction N1 of the opening H62 of the vent hole H6 is substantially not parallel to (in this embodiment, for example, approximately perpendicular to) the direction N3 of the opening 713a of one of the second connection holes 713. It must be noted here that the so-called opening means the normal direction of the plane in which the opening is located. The distance between the center of the opening H62 of the vent hole H6 and the center of the opening 712a of the first connection hole 712 is less than or equal to the sum of the outer radius R1 of the opening H62 of the vent hole H6 and the outer radius R2 of the opening 712a of the first connection hole 712. The distance between the center of the opening H62 of the vent hole H6 and one of the planes S1 of the opening 713a of the second connection hole 713 is smaller than the distance between the center of the opening 712a of the first connection hole 712 and the plane S1. Therefore, the vent hole H6 and the first connecting hole 712 can be as close as possible so that the height T1 of the wound cover 710 can be as small as possible to allow the use of the wound cover 710. The patient feels more comfortable.
此外，由於通氣孔H6可選擇性地與通氣管件750連接，所以當患者使用具有此傷口覆蓋件710與通氣管件750的傷口排流組件時，通氣孔H6的通氣功能可藉由通氣管件750而延伸，使得通氣孔H6不易被患者的身體壓到而失去通氣功能。 In addition, since the vent hole H6 is selectively connectable to the vent tube 750, when the patient uses the wound drainage assembly having the wound cover 710 and the vent tube 750, the venting function of the vent H6 can be by the venting tube 750. The extension makes the vent hole H6 less susceptible to being pressed by the patient's body and losing the venting function.
圖7A繪示本發明第六實施例之一種傷口覆蓋件的立體示意圖。圖7B繪示圖7A之傷口覆蓋件配置有管件的立體示意圖。請參考圖7A與圖7B，本實施例之傷口覆蓋件810與第五實施例之傷口覆蓋件710的不同之處在於傷口覆蓋件810更包括一注入孔816。注入孔816與通氣孔H7配置於第一連接孔812的兩側。值得注意的是，通氣孔H7僅經由傷口覆蓋件810之內部空間而與第一連接孔812連通。 7A is a perspective view of a wound cover of a sixth embodiment of the present invention. 7B is a perspective view of the wound cover of FIG. 7A configured with a tubular member. Referring to FIGS. 7A and 7B, the wound cover 810 of the present embodiment is different from the wound cover 710 of the fifth embodiment in that the wound cover 810 further includes an injection hole 816. The injection hole 816 and the vent hole H7 are disposed on both sides of the first connection hole 812. It is to be noted that the vent hole H7 communicates with the first connection hole 812 only via the inner space of the wound cover 810.
連接管件830之一端適於配置於第一連接孔812，而連接管件830之另一端適於連接至抽吸裝置(未繪示)，使得第一連接孔812連通連接管件830之通孔832，進而與抽吸裝置連通。此外，通氣孔H7可選擇性地與一通氣管件850連接，使得通氣孔H7連通通氣管件850之通孔852。另外，注入孔816可選擇性地與一注入管件860連接，使得注入孔816連通注入管件860之通孔862。當患者使用此傷口覆蓋件810與注入管件860時，治療液體經由注入管件860與注入孔816而注入傷口(未繪示)內。 One end of the connecting tube 830 is adapted to be disposed on the first connecting hole 812, and the other end of the connecting tube 830 is adapted to be connected to a suction device (not shown) such that the first connecting hole 812 communicates with the through hole 832 of the connecting tube 830, Further, it is in communication with the suction device. Further, the vent hole H7 is selectively connectable to a vent tube 850 such that the vent hole H7 communicates with the through hole 852 of the vent tube 850. Additionally, the injection aperture 816 can be selectively coupled to an injection tube 860 such that the injection aperture 816 communicates with the through hole 862 of the injection tube 860. When the patient uses the wound cover 810 and the infusion tube 860, the therapeutic liquid is injected into the wound (not shown) via the infusion tube 860 and the injection hole 816.
在本實施例中，通氣孔H7之開口H72、第一連接孔812之開口812a，以及第二連接孔813之開口之間的關係可參考第五實施例之通氣孔H6之開口H62、第一連接孔712之開口712a與第二連接孔713之開口713a之間的關係，於此不再贅述。注入孔816之開口816a的外半徑R5小於第一連接孔812之開口812a的外半徑R4，注入孔816之開口816a的指向實質上平行於第一連接孔812之開口812a的指向。注入孔816之開口816a的中心與第一連接孔812之開口812a的中心的距離小於或等於注入孔 816之開口816a的外半徑R5與第一連接孔812之開口812a的外半徑R4的和。注入孔816之開口816a的中心與第二連接孔813之開口所在之平面S2的距離小於第一連接孔812之開口812a的中心與平面S2的距離。 In the present embodiment, the relationship between the opening H72 of the vent hole H7, the opening 812a of the first connecting hole 812, and the opening of the second connecting hole 813 can be referred to the opening H62 of the vent hole H6 of the fifth embodiment, first. The relationship between the opening 712a of the connection hole 712 and the opening 713a of the second connection hole 713 will not be described herein. The outer radius R5 of the opening 816a of the injection hole 816 is smaller than the outer radius R4 of the opening 812a of the first connection hole 812, and the opening of the opening 816a of the injection hole 816 is directed substantially parallel to the orientation of the opening 812a of the first connection hole 812. The distance between the center of the opening 816a of the injection hole 816 and the center of the opening 812a of the first connection hole 812 is less than or equal to the injection hole. The outer radius R5 of the opening 816a of the 816 is the sum of the outer radius R4 of the opening 812a of the first connecting hole 812. The distance between the center of the opening 816a of the injection hole 816 and the plane S2 where the opening of the second connection hole 813 is located is smaller than the distance between the center of the opening 812a of the first connection hole 812 and the plane S2.
本發明實施例之傷口排流設備具有以下或其他優點。由於通氣孔連通連接管件的通孔與外界環境，所以當抽吸裝置在抽出傷口內之滲出液時，由通氣孔進入通孔的氣流會帶動通孔內由傷口流向抽吸裝置的流體。因此，與習知技術相較，本發明實施例之傷口排流設備運作時的連接管件的通孔內的流體流動性較佳，使得本發明實施例之傷口排流設備對於傷口內的滲出液的抽吸將較有效率。 The wound drainage device of the embodiments of the present invention has the following or other advantages. Since the vent communicates with the through hole of the connecting tube and the external environment, when the suction device draws out the exudate in the wound, the airflow entering the through hole from the vent hole drives the fluid flowing from the wound to the suction device in the through hole. Therefore, compared with the prior art, the fluid flowability in the through hole of the connecting tube during operation of the wound drainage device of the embodiment of the present invention is better, so that the wound drainage device of the embodiment of the present invention has an exudate for the wound. The suction will be more efficient.
