The present invention provides an automatic injection apparatus for performing rapid injection operations. The automatic injection apparatus comprises a sleeve, a driving unit, and an actuating assembly. The sleeve further comprises a channel and a stop portion. The actuating assembly is movably arranged inside the channel, and the actuating assembly further comprises an elastic member, a first part, and a second part.

The stopper 12 is used to limit the moving position or distance of the movable component in the channel 11 relative to the sleeve 10 along the axis L. The sleeve 10 can be made of a relatively solid material, such as plastic material, metal or alloy, but the invention is not limited thereto.
驱动单元20及作动组件30均设置在套筒10的通道11内。在作动设计上，驱动单元20可带动作动组件30朝第一方向移动(在本发明中，前述第一方向定义为接近驱动单元20的方向)，且作动组件30可相对于套筒10及驱动单元20沿着轴线L在通道11内单独移动。依据不同结构设计，驱动单元20可以采用电动驱动或磁力驱动等方式以带动作动组件30朝第一方向移动。The driving unit 20 and the actuating assembly 30 are both arranged in the channel 11 of the sleeve 10 . In terms of the actuating design, the driving unit 20 can drive the actuating assembly 30 to move in a first direction (in the present invention, the aforementioned first direction is defined as a direction approaching the driving unit 20), and the actuating assembly 30 can move relative to the sleeve. 10 and the drive unit 20 move individually along the axis L within the channel 11 . Depending on the structural design, the driving unit 20 may use electric driving or magnetic driving to drive the actuating component 30 to move in the first direction.

It cannot pass through the stopper 12 , and only the elastic member 31 can move freely through the stopper 12 . That is to say, the first component 32 will be restricted from moving in the channel 11 on one side of the stopper 12 , while the second component 33 will be restricted from moving in the channel 11 on the opposite side of the stopper 12 . The first component 32 is disposed between the driving unit 20 and the stopper 12 , and the first component 32 is detachably combined with the driving unit 20 . When the first component 32 is combined with the drive unit 20 , the second component 33 will contact the stopper 12 and be blocked by the stopper 12 , so that the drive unit 20 can drive the first component 32 toward the first axis along the axis L.

Depending on the structural design, the power supply unit 40 can be directly disposed in the channel 11 of the sleeve 10 , for example, at the other end of the channel 11 away from the object to be injected or implanted, or the power supply unit 40 can also be independently disposed outside the channel 11 .

以下将针对本发明的自动注射装置1的第一实施例的作动原理作详细说明。请参考图2及图3，其中图2是本发明的自动注射装置第一实施例在注射操作过程中的示意图，图3是本发明的自动注射装置第一实施例在执行注射操作后的示意图。The operating principle of the first embodiment of the automatic injection device 1 of the present invention will be described in detail below. Please refer to Figures 2 and 3. Figure 2 is a schematic diagram of the first embodiment of the automatic injection device of the present invention during the injection operation. Figure 3 is a schematic diagram of the first embodiment of the automatic injection device of the present invention after the injection operation. .
如图2及图3所示，当使用者想要使用本发明的自动注射装置1来执行注射操作时，首先可通过操作件12控制供电单元40开始供电。因为驱动单元20结合作动组件30的第一部件32，且作动组件30的第二部件33会被止挡部12止挡，使得当供电单元40供电至驱动单元20时，驱动单元20会通过结合部21带动第一部件32的对应结合部322，进而使第一部件32沿着轴线L朝第一方向D1移动，而弹性件31也会随之移动而被拉伸。由于弹性件31可提供的弹性势能与其移动距离的平方呈正比，当弹性件31的移动距离越大，将会储备更多的弹性势能。弹性势能Ep的方程式如下所示：As shown in FIGS. 2 and 3 , when the user wants to use the automatic injection device 1 of the present invention to perform an injection operation, the user can first control the power supply unit 40 to start power supply through the operating member 12 . Because the driving unit 20 is combined with the first component 32 of the actuating assembly 30, and the second component 33 of the actuating assembly 30 will be blocked by the stopper 12, when the power supply unit 40 supplies power to the driving unit 20, the driving unit 20 will The coupling portion 21 drives the corresponding coupling portion 322 of the first component 32, thereby causing the first component 32 to move along the axis L toward the first direction D1, and the elastic member 31 will also move accordingly and be stretched. Since the elastic potential energy provided by the elastic member 31 is proportional to the square of its movement distance, when the movement distance of the elastic member 31 is larger, more elastic potential energy will be stored. The equation for elastic potential energy Ep is as follows:
Figure PCTCN2022106381-appb-000001
Figure PCTCN2022106381-appb-000001
其中k为弹簧弹性系数，x为弹簧移动距离。where k is the elastic coefficient of the spring, and x is the movement distance of the spring.
当驱动单元20带动第一部件32朝第一方向D1移动至设定距离后，驱动单元20即会停止驱动，并将弹性件31保持在拉伸状态。前述设定距离可根据不同的弹性件31或设计需求加以调整或变动。When the driving unit 20 drives the first component 32 to move to the set distance in the first direction D1, the driving unit 20 will stop driving and keep the elastic member 31 in a stretched state. The aforementioned set distance can be adjusted or changed according to different elastic members 31 or design requirements.
当驱动单元20停止驱动后，在设计上，驱动单元20可自动分离第一部件32，或者由使用者通过操作部13控制第一部件32与驱动单元20分离。举例来说，在本实施例中，假设驱动单元20为电机，结合部21为卡勾结构，且对应结合部322为卡扣结构，当驱动单元20原本朝某一方向旋转而停止驱动后，驱动单元20可以自动执行反向旋转，或者通过操作部13执行反向旋转，使得驱动单元20的结 合部21脱离第一部件32的对应结合部322，进而控制第一部件32与驱动单元20分离。When the driving unit 20 stops driving, in terms of design, the driving unit 20 can automatically separate the first component 32 , or the user can control the first component 32 to separate from the driving unit 20 through the operating part 13 . For example, in this embodiment, it is assumed that the driving unit 20 is a motor, the coupling part 21 is a hook structure, and the corresponding coupling part 322 is a buckle structure. When the driving unit 20 originally rotates in a certain direction and stops driving, The driving unit 20 can automatically perform reverse rotation, or perform reverse rotation through the operating portion 13, so that the coupling portion 21 of the driving unit 20 is separated from the corresponding coupling portion 322 of the first component 32, thereby controlling the separation of the first component 32 from the driving unit 20. .
此时，由于弹性件31靠近第一部件32的一侧失去了拉伸外力，在拉伸状态下的弹性件31的弹性势能被释放，使得弹性件31带动第二部件33沿着轴线L朝第二方向D2(即第一方向D1的反方向)快速移动。因此，通过第二部件33可推动前述待植入的物件或待注射的药剂，以执行注射操作。At this time, since the side of the elastic member 31 close to the first component 32 loses the tensile external force, the elastic potential energy of the elastic component 31 in the stretched state is released, so that the elastic component 31 drives the second component 33 toward the axis L along the axis L. The second direction D2 (that is, the opposite direction of the first direction D1) moves quickly. Therefore, the aforementioned object to be implanted or the medicine to be injected can be pushed through the second component 33 to perform the injection operation.
据此，相较于现有技术的自动注射器，本发明的自动注射装置1通过增加弹性件31的弹性势能，即可完成快速注射操作，有效缩短注射操作时间。Accordingly, compared with the automatic injector of the prior art, the automatic injection device 1 of the present invention can complete the rapid injection operation by increasing the elastic potential energy of the elastic member 31, effectively shortening the injection operation time.
以下将针对本发明的自动注射装置1a的第二实施例的结构及作动原理作详细说明。请一并参考图4至图6，其中图4是本发明的自动注射装置第二实施例的剖视图，图5是本发明的自动注射装置第二实施例在注射操作过程中的示意图，图6是本发明的自动注射装置第二实施例在执行注射操作后的示意图。The structure and operating principle of the second embodiment of the automatic injection device 1a of the present invention will be described in detail below. Please refer to Figures 4 to 6 together. Figure 4 is a cross-sectional view of the second embodiment of the automatic injection device of the present invention. Figure 5 is a schematic diagram of the second embodiment of the automatic injection device of the present invention during the injection operation. Figure 6 This is a schematic diagram of the second embodiment of the automatic injection device of the present invention after executing the injection operation.
本发明的自动注射装置第二实施例为前述第一实施例的变化型式。如图4所示，在本发明的自动注射装置1a第二实施例中，驱动单元20a为电磁铁，且第一部件32a为永久磁铁。相较于前述第一实施例，在本实施例中，驱动单元20a取消了结合部的设计，且第一部件32取消了对应结合部的设计，仅通过磁力做为驱动单元20a与第一部件32a之间的结合或分离的驱动力。The second embodiment of the automatic injection device of the present invention is a variation of the aforementioned first embodiment. As shown in Figure 4, in the second embodiment of the automatic injection device 1a of the present invention, the driving unit 20a is an electromagnet, and the first component 32a is a permanent magnet. Compared with the aforementioned first embodiment, in this embodiment, the driving unit 20a cancels the design of the coupling part, and the first component 32 cancels the design of the corresponding coupling part, and only uses magnetic force as the connection between the driving unit 20a and the first component. The driving force for combination or separation between 32a.
如图5所示，当供电单元40供电至驱动单元20时，驱动单元20会產生磁力並於兩側產生相應的磁極，此时配合第一部件32a为永久磁铁的设计，使得驱动单元20及第一部件32a之间形成磁性相吸力，进而驱动第一部件32a沿着轴线L朝第一方向D1移动，而弹性件31也会随之移动而被拉伸。当驱动单元20带动第一部件32朝第一方向D1移动至设定距离x后，驱动单元20與第一部件32因磁性相吸而彼此結合，并将弹性件31保持在拉伸状态。As shown in Figure 5, when the power supply unit 40 supplies power to the drive unit 20, the drive unit 20 will generate magnetic force and generate corresponding magnetic poles on both sides. At this time, with the design of the first component 32a as a permanent magnet, the drive unit 20 and A magnetic attraction force is formed between the first components 32a, thereby driving the first component 32a to move along the axis L toward the first direction D1, and the elastic member 31 will also move accordingly and be stretched. When the driving unit 20 drives the first component 32 to move to the set distance x in the first direction D1, the driving unit 20 and the first component 32 are combined with each other due to magnetic attraction, and keep the elastic member 31 in a stretched state.
此时，在设计上，驱动单元20会自动停止驱动或由使用者通过操作部13控制以停止驱动，使得原本产生的磁力消失；或者驱动单元20会提供反向电流，使得在两侧产生的磁极相反。无论采用前述哪一种设计，在第一部件32无外部磁力吸引，或者受到外部磁性相斥力作用下，第一部件32a会与驱动单元20a分离，进而使得弹性件31带动第二部件33沿着轴线L朝第二方向D2(即第一方向D1的反方向)快速移动。因此，通过第二部件33可推动前述待植入的物件或待注射的药剂，以执行注射操作。At this time, in terms of design, the driving unit 20 will automatically stop driving or be controlled by the user through the operating part 13 to stop driving, so that the originally generated magnetic force disappears; or the driving unit 20 will provide a reverse current, so that the magnetic force generated on both sides will disappear. The magnetic poles are opposite. No matter which of the above designs is adopted, when the first component 32 is not attracted by external magnetic force or is affected by external magnetic repulsion, the first component 32a will separate from the driving unit 20a, so that the elastic member 31 drives the second component 33 along the The axis L moves rapidly toward the second direction D2 (that is, the opposite direction of the first direction D1). Therefore, the aforementioned object to be implanted or the medicine to be injected can be pushed through the second component 33 to perform the injection operation.
