The joint 11 is generally in the shape of a hollow cylinder, and its two ends are connected to the inner tube 12 and the outer tube 13 respectively, so that the inner tube 12 and the outer tube 13 are fluidly connected.

其中，該接頭11與該內管12及/或該外管13之間可拆卸的結合，以使該輸液裝置10於無須使用時，該外管13可相對該內管12卸除。 The connector 11 is detachably connected to the inner tube 12 and/or the outer tube 13, so that the outer tube 13 can be removed relative to the inner tube 12 when the infusion device 10 is not in use.

進一步地，該接頭11利用一盧爾接頭(Luer taper)111之結構與該內管12及/或該外管13之間可拆卸的結合，使該接頭11可以加快與該內管12及/或該外管13之間管道連接或卸除的速度和品質，同時的避免管道連接時容易產生滑脫或是液體滲漏的風險發生。 Furthermore, the connector 11 utilizes a Luer taper 111 structure to be detachably connected to the inner tube 12 and/or the outer tube 13, so that the connector 11 can speed up the speed and quality of connecting or removing the pipes with the inner tube 12 and/or the outer tube 13, and at the same time avoid the risk of slippage or liquid leakage when connecting the pipes.

該內管12較佳由可撓性醫療級材料所製成一中空管狀物，其兩端分別為一置入端121以及一內管組接端122。該內管12於使用時是以該置入端121置入一患者體內，並且以該內管組接端122之一內管開口126對應至體外，該內管組接端122可與該接頭11連接並且使該內管開口126與該接頭11流體連通。 The inner tube 12 is preferably made of a flexible medical-grade material and is a hollow tube. Its two ends are an insertion end 121 and an inner tube assembly connecting end 122 respectively. When in use, the inner tube 12 is inserted into a patient's body through the insertion end 121, and the inner tube opening 126 of the inner tube set connecting end 122 corresponds to the outside of the body. The inner tube set connecting end 122 can be connected to the connector. 11 is connected and the inner tube opening 126 is in fluid communication with the connector 11 .

其中，該內管組接端122包含有一內管封閉件125，用以可選擇的封閉該內管開口126。進一步地，該內管封閉件125包含一連接件1251以及一塞蓋1252。該連接件1251為一具彈性變性能力之桿狀物，其兩端分別連接該內管12於該內管組接端122之外壁以及該塞蓋1252。該塞蓋1252突出一凸部，且該凸部等於或大於該內管開口126之內徑。 The inner tube assembly connection end 122 includes an inner tube closing member 125 for selectively closing the inner tube opening 126 . Further, the inner tube closing part 125 includes a connecting part 1251 and a plug cover 1252. The connecting member 1251 is a rod-shaped object with elastic deformability, and its two ends are connected to the inner tube 12 to the outer wall of the inner tube assembly connecting end 122 and the plug cover 1252 respectively. The plug cover 1252 protrudes a convex portion, and the convex portion is equal to or larger than the inner diameter of the inner tube opening 126 .

該內管封閉件125於使用時，透過彎折該連接件1251使得該塞蓋1252的凸部位置對應該內管開口126，透過將該凸部塞入該內管開口126內以封閉該內管開口126，此時，該凸部受到持該內管開口126內壁夾持而不易脫落，並同時達成抵抗該連接件1251自有彈性恢復力之效果。當欲將該內管開口126開啟時，僅需將該塞蓋1252移除該內管開口126，便可以該內管組接端122與該接頭11連接。 When the inner tube closing member 125 is used, the connecting member 1251 is bent so that the protruding portion of the plug cover 1252 is positioned corresponding to the inner tube opening 126, and the protruding portion is inserted into the inner tube opening 126 to close the inner tube. At this time, the protrusion is clamped by the inner wall of the inner tube opening 126 and is not easy to fall off, and at the same time achieves the effect of resisting the elastic restoring force of the connector 1251. When the inner tube opening 126 is to be opened, the plug cover 1252 only needs to be removed from the inner tube opening 126, and then the inner tube assembly connecting end 122 can be connected to the connector 11.

值得注意之處在於，由於該連接件1251的彈性恢復力，當該塞蓋1252移除該內管開口126時，該連接件1251可維持桿狀，以防止該內管封閉件125影響操作者之使用。 It is worth noting that due to the elastic restoring force of the connecting member 1251, when the plug cap 1252 removes the inner tube opening 126, the connecting member 1251 can maintain a rod shape to prevent the inner tube closure member 125 from affecting the operator's use.

進一步地，由於該內管12是以該置入端121置入體內為需求，該置入端121之外徑呈現逐漸漸縮並封閉形成端面為弧形之一弧形尖端123，且該置入端121之管壁穿設有複數個引流穿孔124。如此該弧形尖端123因其端面較小之接觸面積可以減少阻礙，助於該內管12順暢的置入該患者體內，而引流穿孔124也可以有效的控制一流體(如營養物質或藥物)進入該患者體內時之速度，避免突然一次性過量輸入該流體而造成該患者負擔。 Furthermore, since the inner tube 12 is required to be inserted into the body with the insertion end 121, the outer diameter of the insertion end 121 gradually tapers and is closed to form an arc-shaped tip 123 with an arc-shaped end surface. The pipe wall of the inlet end 121 is provided with a plurality of drainage perforations 124 . In this way, the arc-shaped tip 123 has a relatively small end surface. The small contact area can reduce obstacles and help the inner tube 12 to be smoothly inserted into the patient's body, and the drainage perforation 124 can also effectively control the speed of a fluid (such as nutrients or drugs) entering the patient's body to avoid sudden changes. A one-time overdose of the fluid may cause burden to the patient.

該外管13較佳由可撓性醫療級材料所製成一中空管狀物，其兩端分別為一開放端131以及一外管組接端132。該外管13於使用時透過該外管組接端132與該接頭11連接並且與該接頭11流體連通後，便可經由該外管13於該開放端131之一外管開口136輸入或抽引流體。 The outer tube 13 is preferably a hollow tube made of flexible medical-grade material, and its two ends are an open end 131 and an outer tube assembly connecting end 132 respectively. When the outer tube 13 is connected to the joint 11 through the outer tube assembly connecting end 132 and is in fluid communication with the joint 11, it can be input or pumped through the outer tube opening 136 of the open end 131 of the outer tube 13. Drainage fluid.

其中，該開放端131包含有一外管封閉件135，用以可選擇的封閉該外管開口136。進一步地，該外管封閉件135包含一外管連接件1351以及一外管塞蓋1352。該外管連接件1351具彈性變性能力且其兩端分別連接該外管13於該開放端131之外壁以及該外管塞蓋1352，其中，該外管連接件1351至該開放端131朝向外管組接端132延伸，使得該外管連接件1351與該外管13之開放端131共同形成一鉤狀結構134。 The open end 131 includes an outer tube closing member 135 for selectively closing the outer tube opening 136. Furthermore, the outer tube closing member 135 includes an outer tube connector 1351 and an outer tube plug cover 1352. The outer tube connector 1351 has elastic deformation capability and its two ends are respectively connected to the outer wall of the open end 131 and the outer tube plug cover 1352 of the outer tube 13, wherein the outer tube connector 1351 extends from the open end 131 toward the outer tube assembly end 132, so that the outer tube connector 1351 and the open end 131 of the outer tube 13 together form a hook-shaped structure 134.

該外管塞蓋1352突出一外管凸部，且該外管凸部等於或大於該外管開口136之內徑。該外管封閉件135之使用方式與前述該內管封閉件125大抵相同便不再贅述，值得注意的是，當該外管開口136開啟且該外管連接件1351因其彈性恢復力使其與該外管13之開放端131共同形成該鉤狀結構134時，可以進一步地利用該鉤狀結構134產生掛持功能，有助於操作者使用時放置/收納該外管13，如掛持該外管13於高處懸空，避免其碰到它物而產生汙染風險，或是掛持於操作者手指，使該操作者手部可以騰出空間拿取他物。 The outer tube plug cover 1352 protrudes an outer tube convex portion, and the outer tube convex portion is equal to or larger than the inner diameter of the outer tube opening 136. The use of the outer tube closure 135 is generally the same as the inner tube closure 125 mentioned above and will not be described in detail. It is worth noting that when the outer tube opening 136 is opened and the outer tube connector 1351 forms the hook structure 134 together with the open end 131 of the outer tube 13 due to its elastic restoring force, the hook structure 134 can be further utilized to generate a hanging function, which helps the operator to place/store the outer tube 13 when using it, such as hanging the outer tube 13 in the air at a high place to prevent it from touching other objects and causing contamination risks, or hanging it on the operator's fingers so that the operator's hands can free up space to pick up other objects.

進一步地，本實施例中，該接頭11兩端分別為該盧爾接頭111以及一插設部112。該接頭11利用該盧爾接頭111與該內管12之其中一末端可拆卸的結合，且利用該插設部112插入該外管13之外管組接端132。其中，該插設部112插入該外管組接端132時，該插設部112受到該外管組接端132之內壁夾持而不易脫落，有助於該內管12快速組裝同時保持該接頭11與該外管13結合，以避免該接頭11掉落而導致臨時無法使用之情事發生。 Furthermore, in this embodiment, the two ends of the connector 11 are the Lure connector 111 and an inserting portion 112. The connector 11 utilizes the Lure connector 111 to be detachably connected to one end of the inner tube 12, and utilizes the inserting portion 112 to be inserted into the outer tube assembly connection end 132 of the outer tube 13. When the inserting portion 112 is inserted into the outer tube assembly connection end 132, the inserting portion 112 is clamped by the inner wall of the outer tube assembly connection end 132 and is not easy to fall off, which helps to quickly assemble the inner tube 12 while keeping the connector 11 connected to the outer tube 13, so as to avoid the connector 11 from falling off and causing temporary unusability.

進一步地，該內管組接端122之端部外壁徑向的形成一膨大結構127，使得膨大結構127與該內管組接端122之管壁之間形成一頸部。較佳地，膨大結構127其外觀整體可為多角形狀，如方形或六角形。透過該膨大結構127以及該頸部可有助於操作者握持時止滑以及與該接頭11組裝時施力，優化整體操作感受。 Furthermore, the outer wall of the end of the inner tube assembly end 122 forms a bulging structure 127 in the radial direction, so that a neck is formed between the bulging structure 127 and the tube wall of the inner tube assembly end 122. Preferably, the bulging structure 127 can be a polygonal shape as a whole, such as a square or a hexagon. The bulging structure 127 and the neck can help the operator to prevent slipping when holding and apply force when assembling with the connector 11, thereby optimizing the overall operating experience.
