有關本發明之前述及其他技術內容、特點及功效，在以下配合參考圖式之實施例的詳細說明中，將可清楚的呈現。 The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the embodiments of the invention.
如後附圖1至圖6b所示，本發明實施例提供之氣管用管狀導管100具有外側管110和內側管120，及頸板130。 As shown in FIG. 1 to FIG. 6b, the tubular catheter 100 for an air tube according to an embodiment of the present invention has an outer tube 110 and an inner tube 120, and a neck plate 130.
該外側管110具有插入患者器官內部的外側插入部111及設置在該外側插入部111上端的結合部113。該外側插入部111配合患者氣管的形狀，呈彎曲形，具有一定的長度。 The outer tube 110 has an outer insertion portion 111 inserted into the inside of the patient's organ and a joint portion 113 provided at the upper end of the outer insertion portion 111. The outer insertion portion 111 has a curved shape and a certain length in accordance with the shape of the patient's trachea.
在該外側插入部111的中央位置上形成與氣管內部連通的孔111a。 A hole 111a communicating with the inside of the air tube is formed at a central position of the outer insertion portion 111.
該結合部113包含：一對凸緣部113a,113b，其在該外側插入部111的上端呈圓板型形成，且相互隔開；一對限位部113c，其設置在該凸緣部113a,113b之間。在一對該凸緣部113a，113b之間結合有該頸板130，該頸板130因該限位部113c在結合狀態下無法旋轉，被固定的同時可防止其移動。在最前端的該凸緣部113a上形成一切口槽113d，該內側管120的上端上所設置的固定部件123的限位鈎123a可穿過該切口槽113d。 The joint portion 113 includes a pair of flange portions 113a, 113b which are formed in a disc shape at the upper end of the outer insert portion 111 and are spaced apart from each other, and a pair of stopper portions 113c which are provided at the flange portion 113a Between 113b. The neck plate 130 is coupled between the pair of flange portions 113a and 113b. The neck plate 130 is prevented from rotating while being restrained by the stopper portion 113c in the coupled state. A groove 113d is formed in the flange portion 113a at the foremost end, and the stopper hook 123a of the fixing member 123 provided on the upper end of the inner tube 120 can pass through the slit groove 113d.
該內側管120具有插入該外側管110內部的內側插入部121和設置在內側插入部121上端的固定部件123。該內側 管120起到引導管的作用，用在對患者氣管內部進行消毒或其他治療需要放入其它醫療器械(消毒器械或吸收器械等)時。因此，該內側插入部121具有和該外側管110的外側插入部111配合的長度，並具有相同的曲率，且為相同的聚四氟乙烯材質製成。該固定部件123設置在該內側插入部121的上端，並可旋轉。由此可見，在將該內側插入部121插入到該外側管110的外側插入部111的狀態下(請參考第6a圖)，該固定部件123的限位鈎123a夾在該凸緣部113a的切口槽113d內，使其旋轉時，該限位鈎123a如圖6b所示，從該切口槽113d中脫離，使該內側管120與該外側管110結合且不分開。 The inner tube 120 has an inner insertion portion 121 inserted into the inner portion of the outer tube 110 and a fixing member 123 provided at an upper end of the inner insertion portion 121. The inner side The tube 120 functions as a guide tube for use in sterilizing or otherwise treating the inside of the patient's trachea when other medical devices (sterilization or absorption devices, etc.) need to be placed. Therefore, the inner insertion portion 121 has a length that fits with the outer insertion portion 111 of the outer tube 110, has the same curvature, and is made of the same polytetrafluoroethylene material. The fixing member 123 is provided at the upper end of the inner insertion portion 121 and is rotatable. Thus, in a state in which the inner insertion portion 121 is inserted into the outer insertion portion 111 of the outer tube 110 (refer to FIG. 6a), the limit hook 123a of the fixing member 123 is sandwiched by the flange portion 113a. When the inside of the slit groove 113d is rotated, the stopper hook 123a is detached from the slit groove 113d as shown in Fig. 6b, and the inner tube 120 is joined to the outer tube 110 without being separated.
另外，該頸板130結合在該外側管110的結合部113上，該外側管110在插入患者氣管的狀態下不旋轉，可維持原位置不動，並與患者頸部的紗布連接。該頸板130由柔軟的矽材料形成，具有結合在該結合部113上的結合孔131及與連接帶連接的一對連接孔132。該結合孔131在該頸板130的中央部分形成，該連接孔132以該結合孔131為中心，兩端部對稱形成。該結合孔131夾在該內側管110的結合部113的凸緣部113a，113b之間並與其結合。此時，該頸板130為矽材料，柔軟富有彈性，可變形及復原，因此該結合孔131可強制性的擴張，使該凸緣部113a穿過，並容易的夾在兩個凸緣部113a，113b之間。 In addition, the neck plate 130 is coupled to the joint portion 113 of the outer tube 110. The outer tube 110 does not rotate in a state of being inserted into the patient's trachea, and can maintain the original position and is connected to the gauze of the patient's neck. The neck plate 130 is formed of a soft enamel material, and has a coupling hole 131 coupled to the joint portion 113 and a pair of connection holes 132 connected to the connecting belt. The coupling hole 131 is formed in a central portion of the neck plate 130. The coupling hole 132 is centered on the coupling hole 131, and both end portions are symmetrically formed. The coupling hole 131 is sandwiched between and coupled to the flange portions 113a, 113b of the joint portion 113 of the inner tube 110. At this time, the neck plate 130 is made of a crucible material, which is soft and elastic, deformable and recoverable, so that the coupling hole 131 can be forcibly expanded, the flange portion 113a is passed through, and is easily sandwiched between the two flange portions. Between 113a and 113b.
該頸板130還具有一鎖槽133，其自該結合孔131的內側引入形成。該鎖槽133位於一對結合孔131的之間，並相互對稱。該鎖槽133之形狀與該結合部113的限位部113c的形狀對應，因此在該頸板130結合在該結合部113的狀態下，限位部113c可相對固定結合。如前述該鎖槽133和限位部113c可相對穩定的結合，該頸板130在結合在該結合部113的狀態下，可不動且維持固定。 The neck plate 130 also has a lock groove 133 which is formed to be introduced from the inner side of the coupling hole 131. The lock groove 133 is located between the pair of coupling holes 131 and is symmetrical to each other. The shape of the lock groove 133 corresponds to the shape of the limiting portion 113c of the joint portion 113. Therefore, in a state where the neck plate 130 is coupled to the joint portion 113, the stopper portion 113c can be relatively fixedly coupled. As described above, the lock groove 133 and the limiting portion 113c can be relatively stably coupled, and the neck plate 130 can be fixed and fixed while being coupled to the joint portion 113.
根據前述之結構，材質不同的外側管110和頸板130可藉由簡單的方法結合在一起，不需要另外的連接部件，可將頸板130堅固的結合在外側管110上，提升產品的信賴性。 According to the foregoing structure, the outer tube 110 and the neck plate 130 having different materials can be combined by a simple method, and the neck plate 130 can be firmly bonded to the outer tube 110 without additional connecting members, thereby enhancing the reliability of the product.
