現有人體皮下注射藥液的藥物注射系統，其主要係使用能手動或電動操作的注射機構連接藥劑容器，使其能以注射機構中的針組刺入人體，留下針組中的軟針維持刺入人體皮下，收回硬針，再藉由手動或電動方式驅動將藥液通過刺入入體的軟針注射於人體皮下組織。The existing drug injection system for subcutaneous injection of liquid medicine in the human body mainly uses an injection mechanism that can be manually or electrically operated to connect a drug container, so that the needle set in the injection mechanism can be inserted into the human body, and the soft needle in the needle set is left to remain inserted into the subcutaneous tissue of the human body, and the hard needle is retracted, and then the liquid medicine is injected into the subcutaneous tissue of the human body through the soft needle inserted into the body by manual or electrical means.
前述注射機構能具有軟針、硬針複合式針組提供人體皮下注射的組件，但是現有注射機構係利用複雜的出針操作機構來執行，造成針組以軟針套設於硬針外側的型態刺入人體後抽出硬針、留下軟針於人體的操作方式存在有操作動作較為繁瑣的問題。The aforementioned injection mechanism can have a soft needle and a hard needle combination needle assembly to provide components for subcutaneous injection in the human body, but the existing injection mechanism is operated using a complex needle removal operation mechanism, resulting in the needle assembly being inserted into the human body in the form of a soft needle sleeve arranged on the outside of the hard needle, and then the hard needle is withdrawn, leaving the soft needle in the human body. There is a problem that the operation action is relatively cumbersome.
再者，基於現有注射機構前述問題，與該注射機構結合的轉接機構連接於藥物儲存機構後，對於藥液的輸送路徑也相對複雜，且藥物注射系統中各機構之間的組合構造也難以提供較理想的注射方式。實有必要進一步對該藥物注射系統中的出針機構進行優化的設計。Furthermore, based on the aforementioned problems of the existing injection mechanism, after the adapter mechanism combined with the injection mechanism is connected to the drug storage mechanism, the delivery path of the drug solution is relatively complicated, and the combination structure between the mechanisms in the drug injection system is also difficult to provide a more ideal injection method. It is necessary to further optimize the design of the needle ejection mechanism in the drug injection system.

此時，如圖25至圖27以及圖22所示，移動至操作行程L的終點位置的出針元件121的扣勾1213能被卡扣於基座111的第二卡扣孔1112中，使該出針元件121呈現被卡扣的鎖定狀態，讓使用者無需維持按壓出針元件121的動作。另一方面，在出針元件121被按壓至終點位置時，觸發該啟動開關62，進入輸液狀態。原本處於注射預備狀態(即待命狀態)的控制單元60接收到啟動開關62發出的信號而啟動馬達70，並經由傳動組件80帶動轉接機構20的活塞桿24依預定速度運動，進而抽取藥物儲存模組2中的藥液通過轉接機構20轉送至針座塞123的注液室1232，再由注液室1232通過管道元件132注入人體內。連接活塞桿24的帶動件83每一次執行推進注射動作時，能觸發計數元件64，控制單元60依據接收計數元件64發出的注射信號決定停止馬達70的時機，其中，控制單元60接收計數元件64被觸發產生的注射信號時，控制單元60能開始計時，給定等待預定秒數後，再令傳動組件80帶動轉接機構20的活塞桿24進行下一次的注射衝程運動。At this time, as shown in FIGS. 25 to 27 and 22, the hook 1213 of the needle-exiting
如圖11及圖20至圖24所示，前述中，活塞桿24被驅動模組3驅動朝後運動時，活塞筒23內的活塞室230呈負壓狀態，轉接機構20的流道轉換閥22的單向輸出閥部222呈關閉狀態，單向輸入閥部221呈開啟狀態，使藥物儲存模組2中的藥液通過容器接頭32、轉接機構20的藥液輸入流道211及單向輸入閥部221進入活塞室230中；接續於活塞桿24被驅動模組3驅動朝前運動時，活塞室230內的藥液被活塞桿24推送而呈正壓狀態，轉接機構20的流道轉換閥22的單向輸出閥部222呈開啟狀態，單向輸入閥部221呈關閉狀態，使活塞室230內的藥液通過轉接機構20的藥液輸出流道212及單向輸出閥部222進入出針機構10的針座塞123的注液室1232，再由注液室1232通過管道元件132注入人體內。As shown in FIG. 11 and FIG. 20 to FIG. 24, in the above, when the piston rod 24 is driven by the driving module 3 to move backward, the piston chamber 230 in the piston cylinder 23 is in a negative pressure state, the one-way output valve portion 222 of the flow channel conversion valve 22 of the adapter mechanism 20 is in a closed state, and the one-way input valve portion 221 is in an open state, so that the drug solution in the drug storage module 2 passes through the container connector 32, the drug solution input flow channel 211 of the adapter mechanism 20 and the one-way input valve portion 221 into the piston chamber 230; When the movable module 3 is driven to move forward, the liquid medicine in the piston chamber 230 is pushed by the piston rod 24 and is in a positive pressure state, the one-way output valve portion 222 of the flow channel conversion valve 22 of the adapter mechanism 20 is in an open state, and the one-way input valve portion 221 is in a closed state, so that the liquid medicine in the piston chamber 230 passes through the liquid medicine output flow channel 212 and the one-way output valve portion 222 of the adapter mechanism 20 into the injection chamber 1232 of the needle seat plug 123 of the needle removal mechanism 10, and then is injected into the human body from the injection chamber 1232 through the pipeline element 132.
如圖11及圖20至圖24所示，待控制單元60依據計數元件64發出的注射信號次數判斷達到藥物目標總輸液量後，停止馬達70，結束注射動作。使用者即可取下藥物注射系統，其中接觸端蓋113藉由彈性元件114的彈力作用而凸出殼體11，並脫離確裝開關63，使確裝開關63對控制單元60發出信號，而切換至閒置狀態，且使管道元件132位於凸出殼體11外的接觸端蓋113內部，藉由接觸端蓋113包覆在管道元件132，確保使用安全性。As shown in FIG. 11 and FIG. 20 to FIG. 24 , after the control unit 60 determines that the total target drug infusion volume has been reached according to the number of injection signals sent by the counting element 64, the motor 70 is stopped to end the injection action. The user can then remove the drug injection system, wherein the contact end cap 113 protrudes from the housing 11 by the elastic force of the elastic element 114 and is disengaged from the mounting switch 63, so that the mounting switch 63 sends a signal to the control unit 60 to switch to an idle state, and the pipeline element 132 is located inside the contact end cap 113 protruding from the housing 11, and the contact end cap 113 covers the pipeline element 132 to ensure safety in use.
此外，藥物注射系統的控制單元60還能透過其內建的控制程式，結合確裝開關63、包括相異色光的第一發光元件(如藍光發光元件)及第二發光元件(如紅光發光元件)的指示燈65及聲音產生器66等，提供燈光及聲音的警示作用與安全機制，以下詳細進行說明。In addition, the control unit 60 of the drug injection system can also provide light and sound warning functions and safety mechanisms through its built-in control program, combined with a fixed switch 63, an indicator light 65 including a first light-emitting element (such as a blue light-emitting element) and a second light-emitting element (such as a red light-emitting element) of different colors, and a sound generator 66, which is explained in detail below.
為了表示藥物注射系統的使用狀態及警示目的，指示燈65在控制單元60控制下，指示燈65能根據不同的狀態，使能發出相異色光的第一發光元件(如藍光發光元件)及第二發光元件(如紅光發光元件)會分別對應發光或熄滅。In order to indicate the use status of the drug injection system and for warning purposes, the indicator light 65 is controlled by the control unit 60. According to different states, the first light emitting element (such as a blue light emitting element) and the second light emitting element (such as a red light emitting element) that can emit light of different colors will light up or go out respectively.
當絕緣片55被抽起時，電能供給單元53經由電連接件54驅動模組3的控制單元60供電，如果控制單元60判斷電能供給單元53的電量大於一預設數值或比例，則正常進入一閒置狀態，指示燈65的第一發光元件(藍光發光元件)及第二發光元件(紅光發光元件)受控亮起，並且聲音產生器66受控發出提示聲音，其後，第二發光元件(紅光發光元件)受控熄滅，第一發光元件(藍光發光元件)保持發光。若控制單元60判斷電能供給單元53的電量小於一預設數值或比例，例如電量小於原始儲存電量的25%，則指示燈65的第二發光元件(紅光發光元件)受控亮起並進入閃爍循環，聲音產生器66受控發出警示聲，其後第二發光元件(紅光發光元件)受控熄滅，藥物注射系統因電能供給單元53的電能不足而自動關機並鎖定，無法再行使用以維持安全性。When the insulating
當藥物注射系統貼附至人體時，接觸端蓋113推抵抵接片56而觸動確裝開關63，確裝開關63對控制單元60發出一確裝信號，使藥物注射系統的控制單元60切換至注射預備狀態(即待命狀態)。在待命狀態下，若貼附狀態發生鬆動，接觸端蓋113無法維持觸動確裝開關63，則在控制單元60控制下會回復至閒置狀態。如果在一特定時間內(例如:10秒)使用者重新完成貼附，讓接觸端蓋113回復至觸動確裝開關63，則可回復至待命狀態。若超過該特定時間，仍無法讓接觸端蓋113回復至觸動確裝開關63，則在控制單元60控制下，令藥物注射系統自動關機並鎖定。When the drug injection system is attached to the human body, the contact end cover 113 pushes against the contact piece 56 to trigger the installation switch 63, and the installation switch 63 sends a installation signal to the control unit 60, so that the control unit 60 of the drug injection system switches to the injection preparation state (i.e., the standby state). In the standby state, if the attachment state becomes loose, the contact end cover 113 cannot maintain the activation of the installation switch 63, and it will return to the idle state under the control of the control unit 60. If the user re-attaches within a specific time (for example: 10 seconds), the contact end cover 113 returns to the activation of the installation switch 63, and then it can return to the standby state. If the contact end cover 113 still cannot be restored to the triggering confirmation switch 63 after the specified time, the drug injection system is automatically shut down and locked under the control of the control unit 60.
當藥物注射系統正確貼附至人體，在出針元件121被按壓至終點位置時，觸發該啟動開關62進入輸液狀態。在輸液狀態下，若貼附狀態鬆動，讓接觸端蓋113無法維持觸動確裝開關63，則在控制單元60控制下，令指示燈65的第二發光元件(紅光發光元件)亮起，並令聲音產生器66發出警示聲。如果在一特定時間內(例如5秒)使用者能重新進行貼附，讓接觸端蓋113回復至觸動確裝開關63，則可回復至輸液狀態繼續輸液。若超過該特定時間，仍無法讓接觸端蓋113回復至觸動確裝開關63，則在控制單元60控制下，令藥物注射系統自動關機並鎖定，無法再行使用以維持安全性。When the drug injection system is correctly attached to the human body, when the needle-out
當輸液正常完成後，藥物注射系統進入閒置狀態，在控制單元件60控制下，指示燈65的第一發光元件(藍光發光元件)持續亮一特定時間後熄滅，藥物注射系統被鎖定。When the infusion is completed normally, the drug injection system enters an idle state. Under the control of the control unit 60, the first light-emitting element (blue light-emitting element) of the indicator light 65 continues to light up for a specific time and then goes out, and the drug injection system is locked.
經由以上所述，本發明藥物注射系統在控制單元60透過內建的控制程式，結合確裝開關63、指示燈65及聲音產生器66等系統化的組合，在藥物注射系統的使用過程中，能夠提供燈光及聲音的警示作用與安全機制，確保本發明藥物注射系統的使用安全性。As described above, the drug injection system of the present invention can provide light and sound warning functions and safety mechanisms during the use of the drug injection system through the built-in control program in the control unit 60, combined with the systematic combination of the installation switch 63, the indicator light 65 and the sound generator 66, thereby ensuring the safety of the use of the drug injection system of the present invention.
