Description
本發明係關於注射器技術領域，尤指一種具有調整注射劑量功能的注射機構及注射器。 The present invention relates to the field of syringe technology, and in particular to an injection mechanism and syringe with the function of adjusting the injection dosage.
在藥劑液注射的安全規範下，現有注射器已具備有計量注射的功能。亦即計量型注射器組裝藥劑瓶後，藉由按壓注射器後端的推桿動作，以及結合注射器內部的驅動機構的連動，用以推動藥劑瓶內的活塞移動一定行程距離，進而通過藥劑瓶前端連接的針頭輸出一定劑量的藥劑液。 Under the safety regulations for injection of liquid medicine, existing syringes already have the function of metered injection. That is, after the metered syringe is assembled with the medicine bottle, by pressing the push rod at the rear end of the syringe and combining with the linkage of the driving mechanism inside the syringe, the piston in the medicine bottle is pushed to move a certain distance, and then a certain amount of liquid medicine is output through the needle connected to the front end of the medicine bottle.
在現有計量型注射器中，部分注射器的注射機構利用其劑量控制機能構造設計，在注射機構連接藥劑瓶後，能控制每一次的注射劑量外，並於重複使用到達一定次數後予以鎖定，藉此提示注射器必須整個拋棄，確保注射筆的使用安全性。 In existing metered syringes, the injection mechanism of some syringes utilizes its dosage control function structure design. After the injection mechanism is connected to the medicine bottle, it can control the injection dosage each time, and lock it after a certain number of repeated uses, so as to remind the whole syringe to be discarded, ensuring the safety of the injection pen.
前述現有的計量型注射器雖能提供輸出固定劑量的藥劑液的功能，但是，注射器的使用，通常須依據不同注射對象的需求而調整注射劑量。現有計量型注射器因欠缺調整注射劑量的功能，難以符合不同使用者的需求。 Although the aforementioned existing metered syringes can provide the function of outputting a fixed dose of liquid medicine, the use of the syringe usually requires adjusting the injection dose according to the needs of different injection targets. Existing metered syringes lack the function of adjusting the injection dose and are difficult to meet the needs of different users.
為了解決前述無法調整注射劑量的問題，在現有的計量型注射器中，部分注射器採用可調整注射劑量的注射機構，使其能夠符合不同使用者的不同注射劑量的使用需求。該注射機構利用其藥瓶連接裝置組接藥瓶，再以可調式推進裝置裝設於藥瓶連接裝置中及伸入藥瓶內，藥瓶連接裝置的轉鈕能驅動可調式推進裝置的推桿朝後移動至預定的刻度，在注射時，按壓推桿即能使藥瓶輸出預定劑量的藥液，使注射器能夠依據不同注射對象的需求而調整注射劑量。 In order to solve the aforementioned problem of being unable to adjust the injection dose, some of the existing metered syringes use an injection mechanism with adjustable injection dose, so that it can meet the different injection dose requirements of different users. The injection mechanism uses its medicine bottle connection device to assemble the medicine bottle, and then an adjustable push device is installed in the medicine bottle connection device and extends into the medicine bottle. The knob of the medicine bottle connection device can drive the push rod of the adjustable push device to move backward to a predetermined scale. When injecting, pressing the push rod can make the medicine bottle output a predetermined dose of liquid medicine, so that the syringe can adjust the injection dose according to the needs of different injection objects.
前述注射器中，具有調整注射劑量的注射機構雖能連接裝有藥液的藥瓶，提供使用者依醫師的處方調整注射劑量再進行注射。但是，該注射器的注射機構執行注射的過程中，須由使用者全程按壓注射機構的注射推桿，使用操作上較為費力，而且，該注射器的注射機構再一次執行注射動作時，須手動操作復位，使用上較不方便。 In the aforementioned syringe, the injection mechanism with an adjustable injection dose can be connected to a medicine bottle containing liquid medicine, allowing the user to adjust the injection dose according to the doctor's prescription before injection. However, during the injection process, the user must press the injection plunger of the injection mechanism throughout the process, which is laborious to operate. Moreover, when the injection mechanism of the syringe performs the injection action again, it must be manually reset, which is inconvenient to use.
本發明之目的在於提供一種具有調整注射劑量功能的注射機構及注射器，解決現有注射器的部分注射機構僅能提供多次相同注射劑量的定量注射功能，無法適應不同注射對象的不同注射劑量需求，以及依醫師的處方指示調整注射劑量的問題，以及部分注射機構僅能調整注射劑量，但使用上較費力及操作不便等問題。 The purpose of the present invention is to provide an injection mechanism and a syringe with the function of adjusting the injection dose, so as to solve the problem that some injection mechanisms of existing syringes can only provide the quantitative injection function of multiple injection doses of the same injection dose, cannot adapt to the different injection dose requirements of different injection objects, and cannot adjust the injection dose according to the doctor's prescription instructions, and some injection mechanisms can only adjust the injection dose, but it is laborious and inconvenient to use.

When the dosage adjustment knob is connected to the tube, the dosage adjustment knob can rotate the tube; a driving ring is installed in the tube and is screwed to the injection push rod; an elastic element is arranged in the tube, and the elastic element is located between the driving ring and the tube. The elastic element is provided between the tube and the dosage adjusting knob, and can provide elastic force to connect the tube to the dosage adjusting knob, and when the dosage adjusting knob rotates the tube, the elastic element is acted upon by the driving ring to generate an elastic potential energy; and a pressing member, which is installed at the rear end of the dosage adjusting knob, and the pressing member can trigger the tube to separate from the dosage adjusting knob, so that the elastic element releases the elastic potential energy to push the driving ring to drive the injection pusher The rod is displaced forward in a spiral motion; and a clutch control assembly is installed inside the front end of the housing, and when the dosage adjustment knob rotates the tube, the clutch control assembly can limit the injection push rod, and when the tube is triggered to disengage from the dosage adjustment knob, the clutch control assembly can connect to the tube. After the injection push rod completes the injection action, the elastic element drives the tube to disengage from the clutch control assembly and reset.
為了達成前述目的，本發明另外提出具有調整注射劑量功能的注射器係包括：一如上所述的具有調整注射劑量功能的注射機構；以及一藥瓶套管，該藥瓶套管能套設於所述藥瓶的外側並組接於該外殼的前端。 In order to achieve the above-mentioned purpose, the present invention further proposes a syringe with the function of adjusting the injection dose, which includes: an injection mechanism with the function of adjusting the injection dose as described above; and a medicine bottle sleeve, which can be sleeved on the outer side of the medicine bottle and assembled to the front end of the shell.
藉由前述注射機構及包括注射機構的注射器等整體組成構造的發明，其組接藥瓶後執行注射動作時，至少具備以下功效： Through the invention of the above-mentioned injection mechanism and the overall structure of the syringe including the injection mechanism, when it is assembled with the medicine bottle and performs the injection action, it has at least the following effects:
1、具備調整注射劑量功能：該注射機構利用設於該外殼中的注射劑量調整組件連接注射推桿，藉由劑量調整旋鈕轉動管件上，並利用管件帶動驅動環位移而使彈性元件產生彈力位能，進而在按壓件觸發管件脫離劑量調整旋鈕時，使彈性元件釋放彈力位能而推動驅動環來驅動注射推桿朝前螺旋位移，使該注射機構具備調整注射劑量功能。 1. With the function of adjusting the injection dose: The injection mechanism uses the injection dose adjustment assembly in the housing to connect the injection push rod, rotates the tube by the dose adjustment knob, and uses the tube to drive the driving ring to move so that the elastic element generates elastic potential energy. When the pressing piece triggers the tube to separate from the dose adjustment knob, the elastic element releases the elastic potential energy and pushes the driving ring to drive the injection push rod to move forward spirally, so that the injection mechanism has the function of adjusting the injection dose.
2、能重複多次使用：該注射機構利用裝設該外殼的前端的內部的離合控制組件，在該劑量調整旋鈕旋轉該管件時，該離合控制組件能限位該注射推桿； 在觸發該管件脫離該劑量調整旋鈕時，該離合控制組件能連接該管件，在該注射推桿完成注射動作後，藉由該彈性元件驅動該管件脫離該離合控制組件復位，藉此，使該注射機構能重複多次調整注射劑量執行注射動作。 2. Can be used repeatedly: The injection mechanism uses the clutch control assembly installed inside the front end of the housing. When the dosage adjustment knob rotates the tube, the clutch control assembly can limit the injection push rod; when the tube is triggered to disengage from the dosage adjustment knob, the clutch control assembly can connect to the tube. After the injection push rod completes the injection action, the elastic element drives the tube to disengage from the clutch control assembly and reset it, thereby enabling the injection mechanism to adjust the injection dosage and perform the injection action repeatedly.
3、操作省力、簡便：承上所述，該注射機構利用設於該外殼中的注射劑量調整組件連接注射推桿，藉由劑量調整旋鈕轉動管件，同時利用管件帶動驅動環位移而使彈性元件產生彈力位能，在按壓件觸發管件脫離劑量調整旋鈕時，該注射機構是利用彈性元件釋放的彈力位能經由驅動環來驅動注射推桿朝前螺旋位移，使該注射機構具備操作省力且簡便的技術效果。 3. Effortless and simple operation: As mentioned above, the injection mechanism uses the injection dosage adjustment assembly in the housing to connect the injection push rod, and the dosage adjustment knob rotates the pipe fitting, and at the same time, the pipe fitting drives the driving ring to move so that the elastic element generates elastic potential energy. When the pressing member triggers the pipe fitting to separate from the dosage adjustment knob, the injection mechanism uses the elastic potential energy released by the elastic element to drive the injection push rod to move forward spirally through the driving ring, so that the injection mechanism has the technical effect of labor-saving and simple operation.
本發明的注射機構及注射器還能進一步提供精準調整注射劑量的功能，其中利用該外殼具有一刻度視窗，該管件的外周面環列分布設置複數劑量刻度；在該劑量調整旋鈕連接該管件的狀態，該劑量調整旋鈕能轉動該管件上的任一所述劑量刻度移至該刻度視窗；在該劑量調整旋鈕旋轉該管件的一所述劑量刻度移動至該刻度視窗時，該彈性元件受該驅動環的作用而產生對應所述劑量刻度的所述彈力位能，並且該離合控制組件限位該注射推桿。藉此，使該注射機構及該注射器能提供使用者依醫師處方精準地調整注射劑量。 The injection mechanism and syringe of the present invention can further provide the function of accurately adjusting the injection dose, wherein the outer shell has a scale window, and the outer circumference of the tube is provided with a plurality of dose scales arranged in a circular pattern; when the dose adjustment knob is connected to the tube, the dose adjustment knob can rotate any dose scale on the tube to move to the scale window; when the dose adjustment knob rotates a dose scale of the tube to move to the scale window, the elastic element is acted upon by the driving ring to generate the elastic potential energy corresponding to the dose scale, and the clutch control assembly limits the injection plunger. In this way, the injection mechanism and the syringe can provide the user with the ability to accurately adjust the injection dose according to the doctor's prescription.
本發明的注射機構及注射器還能進一步提供鎖定功能，其中，利用注射機構中，注射推桿的外周面具有一正向螺旋導槽及一反向螺旋導槽，該注射推桿位於該驅動環後方的後端具有一擋止部，該驅動環中形成一正向螺旋部，與該正向螺旋導槽螺接配合；該離合控制組件包括連接部件及設於連接部中的離合控制環，離合控制環中形成一反向螺旋部，反向螺旋部與注射推桿的反向螺旋導槽螺接配合，該離合控制環能與***作的管件相對離合；連接部件能限制離合控制環僅能定點被驅動反向旋轉，連接部件中具有正向螺接部，與注射推桿的正向螺旋導槽螺接配合。藉此組成構造，注射機構的藥瓶內的藥劑液用完時，注射推桿的後端的擋止部位於驅動環的後方限位；或是藥瓶內剩 餘的藥劑液少於預定注射劑量，注射推桿的後端的擋止部相對於驅動環的後側的抵接環的距離小於預定注射劑量的運動行程時，當使用者旋轉劑量調整旋鈕轉動管件帶動驅動環被注射推桿的後端的擋止部限位時，使用者即無法再旋轉劑量調整旋鈕至管件至更大的注射劑量位置，而呈鎖定狀態。 The injection mechanism and the syringe of the present invention can further provide a locking function, wherein, in the injection mechanism, the outer peripheral surface of the injection push rod has a forward spiral guide groove and a reverse spiral guide groove, the rear end of the injection push rod located behind the driving ring has a stop portion, and a forward spiral portion is formed in the driving ring and threadedly matched with the forward spiral guide groove; the clutch control assembly includes a connecting component and a clutch control ring arranged in the connecting component, a reverse spiral portion is formed in the clutch control ring, and the reverse spiral portion is threadedly matched with the reverse spiral guide groove of the injection push rod, and the clutch control ring can relatively clutch with the operated pipe fitting; the connecting component can limit the clutch control ring to only be driven to rotate in the reverse direction at a fixed point, and the connecting component has a forward threaded portion, which is threadedly matched with the forward spiral guide groove of the injection push rod. With this structure, when the liquid medicine in the medicine bottle of the injection mechanism is used up, the stopper at the rear end of the injection push rod is limited behind the driving ring; or when the liquid medicine remaining in the medicine bottle is less than the predetermined injection amount, the distance between the stopper at the rear end of the injection push rod and the abutment ring on the rear side of the driving ring is less than the movement stroke of the predetermined injection amount, when the user rotates the dosage adjustment knob to rotate the tube to drive the driving ring to be limited by the stopper at the rear end of the injection push rod, the user can no longer rotate the dosage adjustment knob to the tube to a larger injection amount position, and the injection push rod is locked.

關於本發明注射機構1及具有該注射機構1的注射器的使用情形，為便於本發明的說明，以具有注射機構1的注射器作為說明主體，具體說明如下。 Regarding the use of the injection mechanism 1 of the present invention and the syringe having the injection mechanism 1, for the convenience of explaining the present invention, the syringe having the injection mechanism 1 is used as the main body of the explanation, and the specific explanation is as follows.
如圖20及圖14所示，使用前的初始狀態，藥瓶2藉由該藥瓶套管3組接於注射機構1的前端，裝有藥瓶2的藥瓶套管3hapi外側套設護蓋4，該管件20的劑量刻度標記組21的”0.-(mg)”刻度位於外殼10的刻度視窗13。於使用前，將護蓋4取下，將內部裝有針頭5的針頭護套組6安裝在藥瓶套管3的前端，再取下針頭5的外側的針頭護套組6，針頭5裝設於藥瓶套管3馝前端的針頭連接端部31，且該針頭5通過該藥瓶套管3的前端且穿刺連通該藥瓶2內。 As shown in Figures 20 and 14, in the initial state before use, the medicine bottle 2 is connected to the front end of the injection mechanism 1 through the medicine bottle sleeve 3, and the medicine bottle sleeve 3 containing the medicine bottle 2 is covered with a protective cover 4 on the outside, and the "0.-(mg)" scale of the dosage scale mark group 21 of the tube 20 is located in the scale window 13 of the outer shell 10. Before use, the protective cover 4 is removed, and the needle sheath group 6 with the needle 5 inside is installed on the front end of the medicine bottle sleeve 3, and then the needle sheath group 6 on the outside of the needle 5 is removed. The needle 5 is installed on the needle connection end 31 at the front end of the medicine bottle sleeve 3, and the needle 5 passes through the front end of the medicine bottle sleeve 3 and punctures the medicine bottle 2.
一般而言，藥瓶2內封裝藥劑液後，藥瓶2內通常會殘留少量的氣泡，如圖21所示，為了避免氣泡注入人體，於人體注射前，先將裝有針頭5的藥瓶2的前端朝上，再輕彈套設於藥瓶2外側的藥瓶套管3數次，使藥瓶2內的氣泡向上移動至藥瓶2頂部後，旋轉注射機構1的劑量調整旋鈕30，帶動管件20的劑量刻度標記組21自”0.-(mg)”刻度旋轉至排氣圖標211”--- -”對準外殼10的刻度視窗13，在裝有針頭5的藥瓶2的前端朝上的狀態下，按壓後端的按壓件90，使驅動注射機構1內的注射推桿80推抵藥瓶2內的活塞2A，使藥瓶2內的氣泡完全排出。 Generally speaking, after the medicine liquid is sealed in the medicine bottle 2, a small amount of bubbles will usually remain in the medicine bottle 2, as shown in FIG21. In order to prevent the bubbles from being injected into the human body, before injecting into the human body, the front end of the medicine bottle 2 equipped with the needle 5 is first facing upward, and then the medicine bottle sleeve 3 arranged on the outer side of the medicine bottle 2 is gently flicked several times to make the bubbles in the medicine bottle 2 move upward to the top of the medicine bottle 2, and then the dosage adjustment knob 30 of the injection mechanism 1 is rotated to drive the dosage scale mark group 21 of the tube 20 to rotate from the "0.-(mg)" scale to the exhaust icon 211"--- -” Align the scale window 13 of the outer shell 10, and with the front end of the medicine bottle 2 equipped with the needle 5 facing upward, press the pressing member 90 at the rear end to drive the injection push rod 80 in the injection mechanism 1 to push against the piston 2A in the medicine bottle 2, so that the bubbles in the medicine bottle 2 are completely discharged.
前述中，旋轉注射機構1的劑量調整旋鈕30帶動管件20的劑量刻度標記組21的排氣圖標211“--- -”至外殼10的刻度視窗13，再按壓按壓件90驅動注射推桿80執行藥瓶2內的氣泡排出的過程，與下述的注射動作相同，故此氣泡排出時，該注射機構1的動作請參照以下注射動作說明。 In the above, rotating the dosage adjustment knob 30 of the injection mechanism 1 drives the exhaust icon 211 "--- -" of the dosage scale mark group 21 of the tube 20 to the scale window 13 of the housing 10, and then pressing the pressing member 90 to drive the injection plunger 80 to execute the process of exhausting the bubbles in the medicine bottle 2, which is the same as the injection action described below. Therefore, when the bubbles are exhausted, please refer to the following injection action description for the action of the injection mechanism 1.
如圖22、圖24至圖28所示，於注射時，先旋轉注射機構1的劑量調整旋鈕30至管件20的劑量刻度標記組21的預定劑量刻度至外殼10的刻度視窗13對準位置，假設：預定注射劑量為0.75mg，即旋轉劑量調整旋鈕30帶動管件20的劑量刻度標記組21自“0.-(mg)”刻度旋轉至“0.75-(mg)”刻度對準刻度視窗13，其次，以針頭5刺入人體的注射部位，再按壓按壓件90執行注射動作。有關前述旋轉設定注射劑量及注射動作的執行步驟如下。 As shown in Figures 22, 24 to 28, during injection, first rotate the dosage adjustment knob 30 of the injection mechanism 1 until the preset dosage scale of the dosage scale mark group 21 of the tube 20 is aligned with the scale window 13 of the housing 10. Assuming that the preset injection dosage is 0.75 mg, the dosage adjustment knob 30 is rotated to drive the dosage scale mark group 21 of the tube 20 to rotate from the "0.-(mg)" scale to the "0.75-(mg)" scale to align with the scale window 13. Next, the needle 5 is inserted into the injection site of the human body, and then the pressing member 90 is pressed to perform the injection action. The execution steps of the aforementioned rotation setting injection dosage and injection action are as follows.
當劑量調整旋鈕30至管件20的劑量刻度標記組21的預定劑量刻度至外殼10的刻度視窗13的過程中，注射推桿80藉由被固定於外殼10中的連接部件70以及被限制於連接部件70中的離合控制環60予以限位，該劑量調整旋鈕30的所述離合卡齒32能與該管件20的後端的卡齒部22能相對嚙合，位於該管件20內的該驅動環50以所述軸向導引部52伸入該管件20內的移動導槽25，故旋轉劑量調整旋鈕30正向旋轉自“0.-(mg)”刻度旋轉至“0.75-(mg)”刻度對準刻度 視窗13時，同時經由劑量調整旋鈕30帶動管件20正向旋轉，並經由管件20帶動驅動環50沿著注射推桿80的正向螺旋導槽801朝後旋轉位移至相對於注射劑量的距離位置，同時經由抵接環41壓縮彈性元件40蓄積彈力位能。 When the dosage adjustment knob 30 is moved to the predetermined dosage scale of the dosage scale mark group 21 of the tube 20 to the scale window 13 of the housing 10, the injection plunger 80 is limited by the connecting member 70 fixed in the housing 10 and the clutch control ring 60 restricted in the connecting member 70, and the clutch tooth 32 of the dosage adjustment knob 30 can be relatively engaged with the tooth portion 22 at the rear end of the tube 20, and the driving ring 50 located in the tube 20 extends into the axial guide portion 52. The moving guide groove 25 in the tube 20, so when the dosage adjustment knob 30 is rotated forward from the "0.-(mg)" scale to the "0.75-(mg)" scale to align the scale window 13, the dosage adjustment knob 30 drives the tube 20 to rotate forward at the same time, and the tube 20 drives the driving ring 50 to rotate backward along the forward spiral guide groove 801 of the injection plunger 80 to a distance position relative to the injection dose, and at the same time, the elastic element 40 is compressed by the abutment ring 41 to accumulate elastic potential energy.
當對按壓件90施以朝前的按壓力量，經由按壓件90推動管件20朝前移動，使管件20後端的卡齒部22脫離該劑量調整旋鈕30的所述離合卡齒32，再使管件20的前端的對位卡槽24與前側的離合控制環60的對位卡齒63相嚙合，接續在彈性元件40的彈力位能作用下，驅動環50被驅動朝前移動至接觸離合控制環60後停止，同時藉由驅動環50的正向螺旋部51與注射推桿80的正向螺旋導槽801的螺接組合構造，搭配連接部件70的正向螺接部71與注射推桿80的正向螺旋導槽801的螺接組合構造的輔助，使注射推桿80在彈力位能作用下朝前螺旋推進，進而經由注射推桿80的前端的活塞抵接件81推動藥瓶2內的活塞2A朝前移動，而自藥瓶2內的預定量藥劑液通過針頭5注射於人體中。 When a forward pressing force is applied to the pressing member 90, the pressing member 90 pushes the pipe 20 forward, so that the tooth portion 22 at the rear end of the pipe 20 disengages from the clutch tooth 32 of the dosage adjustment knob 30, and then the alignment groove 24 at the front end of the pipe 20 engages with the alignment tooth 63 of the clutch control ring 60 at the front side. Then, under the action of the elastic potential energy of the elastic element 40, the driving ring 50 is driven forward to contact the clutch control ring 60 and then stops. At the same time, the driving ring 50 is driven to move forward. The screw connection structure of the forward spiral portion 51 and the forward spiral guide groove 801 of the injection push rod 80, with the assistance of the screw connection structure of the forward spiral portion 71 of the connecting component 70 and the forward spiral guide groove 801 of the injection push rod 80, enables the injection push rod 80 to spirally push forward under the action of elastic potential energy, and then the piston abutment 81 at the front end of the injection push rod 80 pushes the piston 2A in the medicine bottle 2 to move forward, and the predetermined amount of medicine liquid in the medicine bottle 2 is injected into the human body through the needle 5.
如圖22至圖28所示，前述中，注射推桿80朝前螺旋推進的過程中，藉由離合控制環60的反向螺旋部61與注射推桿80的反向螺旋導槽802的螺接組合構造，以及管件20的前端的對位卡槽24與前側的離合控制環60的對位卡齒63相嚙合而連動，故注射推桿80在彈力位能作用下朝前螺旋推進的同時，帶動離合控制環60、該管件20及位於該管件20內的驅動環50同步反向旋轉，直至管件20的劑量刻度的“0.-(mg)”刻度旋回至外殼10的刻度視窗13位置。 As shown in Figures 22 to 28, in the process of the injection push rod 80 spirally advancing forward, the reverse spiral portion 61 of the clutch control ring 60 and the reverse spiral guide groove 802 of the injection push rod 80 are screwed together, and the alignment groove 24 at the front end of the pipe 20 and the alignment tooth 63 of the front clutch control ring 60 are engaged and linked. Therefore, the injection push rod 80 spirally advances forward under the action of the elastic potential energy, and at the same time, drives the clutch control ring 60, the pipe 20 and the drive ring 50 located in the pipe 20 to rotate synchronously in the opposite direction until the "0.-(mg)" scale of the dosage scale of the pipe 20 rotates back to the scale window 13 position of the outer shell 10.
在完成注射後，驅動環50維持在接觸離合控制環60後端的位置，藉由彈性元件40的彈力推動管件20朝後移動，使管件20的前端的對位卡槽24與前側的離合控制環60的對位卡齒63脫離，管件20的後端的卡齒部22重新與該劑量調整旋鈕30的所述離合卡齒32嚙合復位。如此，完成一次的注射動作。在注射動作完成後，使用者以針頭護套6A套設於針頭5的外側，藉由針頭護套 6A作為拆除針頭5的安全輔助工具，安全地自藥瓶套管3的前端拆下針頭5，另以護蓋4套設於藥瓶套管3的外側，留待下次使用。 After the injection is completed, the driving ring 50 maintains the position of contacting the rear end of the clutch control ring 60, and the elastic force of the elastic element 40 pushes the tube 20 to move backward, so that the alignment groove 24 at the front end of the tube 20 is disengaged from the alignment tooth 63 of the front clutch control ring 60, and the tooth portion 22 at the rear end of the tube 20 is re-engaged with the clutch tooth 32 of the dosage adjustment knob 30. In this way, one injection action is completed. After the injection is completed, the user puts the needle sheath 6A on the outside of the needle 5, and uses the needle sheath 6A as a safety auxiliary tool to remove the needle 5. The needle 5 is safely removed from the front end of the medicine bottle sleeve 3, and the protective cover 4 is put on the outside of the medicine bottle sleeve 3 for the next use.
如圖23及圖30所示，依據前述的使用操作方式，直至藥瓶2內的藥劑液用完為止。該注射機構1利用固定於外殼10中的連接部件70限制該離合控制環60僅能定點被驅動反向旋轉之構造，以及離合控制環60與注射推桿80的反向螺旋導槽802的螺接構造等，在旋轉劑量調整旋鈕30時，該注射推桿80是被限位，無法旋轉的。因此，倘若藥瓶2內剩餘的藥劑液少於預定注射劑量時，如圖29所示，注射推桿80後端之擋止部804相對於驅動環50的後側的抵接環41的距離小於預定注射劑量的運動行程，例如：預定注射藥劑液量為0.75mg，藥瓶2內剩餘的藥劑液量為0.5mg時，該擋止部804相對於驅動環50後側的抵接環41的距離僅對應於注射劑量0.5mg的行程距離，故使用者旋轉劑量調整旋鈕30至管件20的劑量刻度標記組21自“0.-(mg)”刻度旋轉至“0.5-(mg)”刻度旋轉至刻度視窗13位置時，驅動環50後側的抵接環41即接觸注射推桿80的後端的擋止部804，該擋止部804產生鎖定作用，使用者無法再旋轉劑量調整旋鈕30至管件20的“0.75-(mg)”刻度對準刻度視窗13。 As shown in FIG. 23 and FIG. 30 , according to the aforementioned use and operation mode, the medicine liquid in the medicine bottle 2 is used up. The injection mechanism 1 uses the connection component 70 fixed in the housing 10 to limit the clutch control ring 60 to be driven to rotate in the opposite direction at a fixed point, and the screw connection structure of the clutch control ring 60 and the reverse spiral guide groove 802 of the injection plunger 80, etc. When the dosage adjustment knob 30 is rotated, the injection plunger 80 is limited and cannot rotate. Therefore, if the amount of liquid medicine remaining in the medicine bottle 2 is less than the predetermined injection amount, as shown in FIG. 29 , the distance between the stopper 804 at the rear end of the injection plunger 80 and the abutment ring 41 at the rear side of the driving ring 50 is less than the travel distance of the predetermined injection amount. For example, if the predetermined injection amount of liquid medicine is 0.75 mg and the amount of liquid medicine remaining in the medicine bottle 2 is 0.5 mg, the distance between the stopper 804 and the abutment ring 41 at the rear side of the driving ring 50 only corresponds to the travel distance of the injection amount of 0.5 mg. Therefore, when the user rotates the dosage adjustment knob 30 until the dosage scale mark group 21 of the tube 20 rotates from the "0.-(mg)" scale to the "0.5-(mg)" scale and rotates to the scale window 13 position, the abutment ring 41 on the rear side of the driving ring 50 contacts the stopper 804 at the rear end of the injection plunger 80, and the stopper 804 produces a locking effect, and the user cannot rotate the dosage adjustment knob 30 until the "0.75-(mg)" scale of the tube 20 is aligned with the scale window 13.
同理，如圖23及圖30所示，當藥瓶2內的藥劑液用完時，注射推桿80的後端的擋止部804在驅動環50的後側的抵接環41的後側也會產生鎖定作用，讓使用者無法再旋轉劑量調整旋鈕30。當藥瓶2內的藥劑液用完時，在針頭護套6A套設於針頭5外側，安全地自藥瓶套管3的前端拆下針頭5後，將護蓋4套設於藥瓶套管3的外側，將注射器連同空藥瓶2一起丟棄，注射器於有限次數使用，確保注射器的使用安全性。 Similarly, as shown in Figures 23 and 30, when the liquid medicine in the medicine bottle 2 is used up, the stopper 804 at the rear end of the injection plunger 80 will also produce a locking effect on the rear side of the abutment ring 41 on the rear side of the driving ring 50, so that the user can no longer rotate the dosage adjustment knob 30. When the liquid medicine in the medicine bottle 2 is used up, after the needle sheath 6A is sleeved on the outer side of the needle 5 and the needle 5 is safely removed from the front end of the medicine bottle sleeve 3, the protective cover 4 is sleeved on the outer side of the medicine bottle sleeve 3, and the syringe is discarded together with the empty medicine bottle 2. The syringe is used for a limited number of times to ensure the safety of the syringe.
