連接器部20在前方末端設置有與注射單元組裝體31、32、33結 合的注射單元結合部21，並且在後方末端設置有具有藥液供給管結合孔26的藥液供給管連結部25，該藥液供給管結合孔26以與結合在注射單元結合部21的注射單元例如注射針31的內部通路連通的方式與藥液供給管40的一端結合。 The connector portion 20 is provided with an injection unit coupling portion 21 coupled to the injection unit assemblies 31, 32, 33 at the front end, and a medical fluid supply tube coupling portion 25 having a medical fluid supply tube coupling hole 26 at the rear end, The medical solution supply tube coupling hole 26 is coupled to one end of the medical solution supply tube 40 so as to communicate with the internal passage of the injection unit, for example, the injection needle 31 coupled to the injection unit coupling portion 21.

如第3b圖所示，注射單元組裝體31、32、33具有注射單元31，注射單元31被轉接頭(adapter)32支撐，在轉接頭32的外周具備多個結合突起33。 As shown in FIG. 3B, the injection unit assemblies 31, 32, and 33 have an injection unit 31, which is supported by an adapter 32, and a plurality of coupling protrusions 33 are provided on the outer periphery of the adapter 32.

在注射單元結合部21設置有緊固螺母35，該緊固螺母35用於將注射單元組裝體31、32、33緊固固定在注射單元結合部21。在將注射單元組裝體31、32、33的轉接頭32的結合突起33插入到緊固螺母35內而與螺紋部36以螺紋結合方式結合之後，在該狀態下使緊固螺母35旋轉，則能夠將注射單元組裝體31、32、33向結合方向拉動而將注射單元31的後端插入到注射單元結合孔22。在該狀態下，若使緊固螺母35持續旋轉而擰緊，則注射單元組裝體31、32、33緊固固定在皮下注射用連接器100A。 The injection unit coupling portion 21 is provided with a fastening nut 35 for fastening and fixing the injection unit assemblies 31, 32, and 33 to the injection unit coupling portion 21. After the coupling protrusion 33 of the adapter 32 of the injection unit assembly 31, 32, 33 is inserted into the fastening nut 35 and screw-coupled with the screw portion 36, the fastening nut 35 is rotated in this state. Then, the injection unit assemblies 31, 32, and 33 can be pulled in the coupling direction to insert the rear end of the injection unit 31 into the injection unit coupling hole 22. In this state, if the fastening nut 35 is continuously rotated and tightened, the injection unit assemblies 31, 32, and 33 are fastened and fixed to the connector 100A for hypodermic injection.

在藥液供給管連結部25的藥液供給管結合孔26內，連結有藥液供給管40。能夠將藥液供給管40推壓到藥液供給管結合孔26的最底端並與之結合，以使通過藥液供給管40供給的藥液不殘留在藥液供給管結合孔26。在這種結合狀態下，能夠防止通過藥液供給管40流入的抗癌劑這樣的高昂的藥液在連接器的空間內以殘餘量剩餘的問題。 A chemical liquid supply tube 40 is connected to the chemical liquid supply tube coupling hole 26 of the chemical liquid supply tube coupling portion 25. The medical solution supply tube 40 can be pushed to the lowest end of the medical solution supply tube coupling hole 26 and coupled thereto, so that the medical solution supplied through the medical solution supply tube 40 does not remain in the medical solution supply tube coupling hole 26. In such a coupled state, it is possible to prevent a problem that a high amount of medical liquid such as an anticancer agent flowing through the medical liquid supply tube 40 remains in the space of the connector in a residual amount.

由於供注射單元組裝體31、32、33結合的注射單元結合部21和固定在患者的皮膚1的支撐架10形成一定的角度a，所以注射單元結合部21相對於支撐架10所接觸的患者的皮膚1自動維持規定角度a，在該狀態下，能夠將與注射單元結合部21結合的注射單元31以規定角度a準確地刺入到皮下。並且，將支撐架10利用膠帶或支撐架夾具50固定於患者的皮膚1。因此，若連接器部20以及注射單元結合部21與支撐架10具有規定角度a，則不僅能夠容易進行皮下注射，在進行皮下注射之後，也能夠容易固定在患者的皮膚1上。 Since the injection unit coupling portion 21 for combining the injection unit assemblies 31, 32, 33 and the support frame 10 fixed to the patient's skin 1 form a certain angle a, the injection unit coupling portion 21 contacts the patient with the support frame 10 The skin 1 automatically maintains a predetermined angle a. In this state, the injection unit 31 coupled to the injection unit coupling portion 21 can be accurately penetrated under the skin at the predetermined angle a. In addition, the support frame 10 is fixed to the patient's skin 1 with an adhesive tape or a support frame jig 50. Therefore, if the connector portion 20 and the injection unit coupling portion 21 and the support frame 10 have a predetermined angle a, not only the subcutaneous injection can be easily performed, but also the patient's skin 1 can be easily fixed after the subcutaneous injection.

連接器部20經由延伸柱18而與支撐架10連結，由此能夠在支撐架10與注射單元結合部21之間確保充足的充裕空間，由此能夠更容易將注射單元31刺入到皮下。 The connector portion 20 is connected to the support frame 10 via the extension column 18, whereby a sufficient ample space can be ensured between the support frame 10 and the injection unit coupling portion 21, whereby the injection unit 31 can be more easily penetrated under the skin.

另外，支撐架10可以通過固定單元固定於患者的皮膚1。固定單元可以由膠帶構成，從而容易將支撐架10固定在患者的皮膚1上。 In addition, the support frame 10 may be fixed to the patient's skin 1 by a fixing unit. The fixing unit may be composed of an adhesive tape, so that it is easy to fix the support frame 10 on the skin 1 of the patient.

作為替代方案，如第3b圖所示，支撐架固定單元可以構成為，在下側設置有附著在患者的皮膚1的膠帶58並且在上側設置有支撐架夾具50，該支撐架夾具50將支撐架10以能夠拆裝的方式結合並固定。支撐架夾具50由下部的固定夾具51和上部的可動夾具52構成。 As an alternative, as shown in FIG. 3b, the support frame fixing unit may be configured such that an adhesive tape 58 attached to the patient's skin 1 is provided on the lower side and a support frame clamp 50 is provided on the upper side, which supports the support frame 10 Combine and fix in a detachable manner. The support jig 50 is composed of a lower fixed jig 51 and an upper movable jig 52.

支撐架10可以在外周面具備至少2個階梯部12，支撐架夾具50可以具備將至少2個階梯部12之間的固定部11夾入結合的插入部53。因此，若將階梯部12之間的固定部11夾入結合到支撐架夾具50的插入部53而進行固定，則注射單元組裝體31、32、33能夠始終固定在一定位置而不移動。 The support frame 10 may include at least two stepped portions 12 on the outer peripheral surface, and the support frame jig 50 may include an insertion portion 53 that sandwiches and couples the fixing portion 11 between the at least two stepped portions 12. Therefore, if the fixing portion 11 between the stepped portions 12 is sandwiched and fixed by the insertion portion 53 coupled to the holder jig 50, the injection unit assemblies 31, 32, and 33 can always be fixed at a certain position without moving.

第4圖至第5b圖示出本發明的第二具體例所涉及的皮下注射用連接器。第6圖至第7圖示出本發明的第三具體例所涉及的皮下注射用連接器，第8圖以及第9圖示出本發明的第四具體例所涉及的皮下注射用連接器。 Figures 4 to 5b show a connector for hypodermic injection according to a second specific example of the present invention. 6 to 7 show the connector for hypodermic injection according to the third specific example of the present invention, and FIGS. 8 and 9 show the connector for hypodermic injection according to the fourth specific example of the present invention.

在第二具體例至第四具體例所涉及的皮下注射用連接器100B、100C、100D的情況下，不同於第一具體例，支撐架10與連接器部20直接連結。在各具體例中，連接器部20相對於支撐架10維持大於0°且在90°以下的角度a。連接器部20相對於支撐架10的角度a優選形成為大致45°，但並不限定於此。第二具體例至第四具體例的皮下注射用連接器100B、100C、100D也與第一具體例的皮下注射用連接器100A同樣，能夠將結合於注射單元結合部21的注射單元31以規定角度a準確地刺入到患者的皮膚1，能夠不依賴於醫護人員的經驗，而是利用機械式動作來容易實現皮下注射。 In the case of the hypodermic connectors 100B, 100C, and 100D according to the second to fourth specific examples, unlike the first specific example, the support frame 10 and the connector portion 20 are directly connected. In each specific example, the connector portion 20 maintains an angle a greater than 0° and 90° or less with respect to the support frame 10. The angle a of the connector portion 20 relative to the support frame 10 is preferably formed at approximately 45°, but it is not limited thereto. The subcutaneous injection connectors 100B, 100C, and 100D of the second to fourth specific examples are similar to the subcutaneous injection connector 100A of the first specific example, and the injection unit 31 coupled to the injection unit coupling portion 21 can be defined The angle a accurately penetrates the skin 1 of the patient, and it can easily realize the subcutaneous injection by using a mechanical action without depending on the experience of medical personnel.

第二具體例至第四具體例所涉及的皮下注射用連接器100B、100C、100D分別包括注射單元結合部21，這些皮下注射用連接器所具備的支撐架10均包括供藥液供給管40連結的藥液供給管連結部25。藥液供給管連結部25構成為與結合在注射單元結合部21的注射單元31連通(參照第4圖至第9圖)。 The subcutaneous injection connectors 100B, 100C, and 100D according to the second to fourth specific examples each include an injection unit coupling portion 21, and the support frame 10 provided in these subcutaneous injection connectors includes a medical fluid supply tube 40 The connected chemical solution supply tube connecting portion 25. The medical liquid supply tube coupling portion 25 is configured to communicate with the injection unit 31 coupled to the injection unit coupling portion 21 (see FIGS. 4 to 9 ).

在第二具體例至第四具體例所涉及的皮下注射用連接器100B、100C、100D中，藥液供給管連結部25具備供藥液供給管40插入的藥液供給管結合孔26。第二具體例的皮下注射用連接器100B的藥液供給管結合孔26在藥 液供給管連結部25的後端沿中心軸方向形成(參照第5a圖以及第5b圖)。在第二具體例所涉及的皮下注射用連接器100B的情況下，若藥液供給管40插入到藥液供給管結合孔26的最底端，則能夠防止通過藥液供給管40流入的抗癌劑這樣的高昂的藥液在連接器的空間內以殘餘量剩餘的問題(參照第5b圖)。 In the hypodermic injection connectors 100B, 100C, and 100D according to the second to fourth specific examples, the medical solution supply tube coupling portion 25 includes the medical solution supply tube coupling hole 26 into which the medical solution supply tube 40 is inserted. The medical solution supply tube coupling hole 26 of the hypodermic injection connector 100B of the second specific example is formed at the rear end of the medical solution supply tube coupling portion 25 in the direction of the central axis (see FIGS. 5a and 5b). In the case of the connector 100B for hypodermic injection according to the second specific example, if the medical solution supply tube 40 is inserted into the lowest end of the medical solution supply tube coupling hole 26, the resistance to the inflow through the medical solution supply tube 40 can be prevented There is a problem that a high chemical liquid such as a cancer agent remains in the space of the connector with a residual amount (see FIG. 5b).

另一方面，第三具體例的皮下注射用連接器100C的藥液供給管結合孔26形成為，在藥液供給管連結部的側面開設有入口(參照第6圖以及第7圖)。即，在第三具體例的皮下注射用連接器100C的情況下，藥液供給管結合孔26向支撐架10的側面開放，從而藥液供給管40結合在支撐架10的側面。另外，第四具體例的皮下注射用連接器100D的藥液供給管結合孔26可以形成為，在藥液供給管連結部25的上表面開設有入口(參照第8圖以及第9圖)。即，在第四具體例的皮下注射用連接器100D的情況下，藥液供給管結合孔26向支撐架10的上表面開放，從而藥液供給管40結合在支撐架10的上表面。在第三具體例以及第四具體例所涉及的皮下注射用連接器100C、100D中也同樣地，若藥液供給管插入到藥液供給管結合孔26的最底端，則能夠防止通過藥液供給管流入的抗癌劑這樣的高昂的藥液在連接器的空間內以殘餘量剩餘的問題。 On the other hand, the medical fluid supply tube coupling hole 26 of the connector for subcutaneous injection 100C of the third specific example is formed so that an inlet is opened on the side surface of the medical fluid supply tube coupling portion (see FIGS. 6 and 7 ). That is, in the case of the connector for subcutaneous injection 100C of the third specific example, the medical solution supply tube coupling hole 26 is opened to the side of the support frame 10, and the medical solution supply tube 40 is coupled to the side of the support frame 10. In addition, the medical fluid supply tube coupling hole 26 of the hypodermic injection connector 100D of the fourth specific example may be formed such that an inlet is opened in the upper surface of the medical fluid supply tube coupling portion 25 (see FIGS. 8 and 9 ). That is, in the case of the connector for subcutaneous injection 100D of the fourth specific example, the medical solution supply tube coupling hole 26 is opened to the upper surface of the support frame 10, so that the medical solution supply tube 40 is coupled to the upper surface of the support frame 10. Similarly, in the hypodermic connectors 100C and 100D according to the third and fourth specific examples, if the medical solution supply tube is inserted into the lowest end of the medical solution supply tube coupling hole 26, the passage of the drug can be prevented There is a problem that a high chemical liquid such as an anticancer agent flowing into the liquid supply pipe is left in the space of the connector with a residual amount.

另一方面，在第二具體例至第四具體例所涉及的皮下注射用連接器100B、100C、100D中，將支撐架10固定在患者的皮膚1的方法與第一具體例的固定方法實質上是相同的，因此省略對此的詳細說明。 On the other hand, in the connectors 100B, 100C, and 100D for hypodermic injection according to the second to fourth specific examples, the method of fixing the support frame 10 to the skin 1 of the patient is substantially the same as the fixing method of the first specific example The above is the same, so a detailed description of this is omitted.
