[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 3 As shown, this application discloses an injection cartridge comprising a top cover 1, a bottom plate 2, and a button-driven assembly 3. The bottom plate 2 is mounted to the top cover 1, forming a storage cavity for storing injections. One end of the storage cavity has an opening 100. The button-driven assembly 3 is mounted to the bottom plate 2, with its end located at the opening 100. When the button-driven assembly 3 is pressed, a single injection drops from the opening 100. The injection cartridge has a matching receiving structure. Pressing the button-driven assembly 3 once causes the assembly to push a single injection into the receiving structure, achieving efficient collection of injections. The injection cartridges are placed horizontally and stacked in an array in an automated pharmacy. A single injection cartridge can store a limited number of injections, allowing the automated pharmacy to store large quantities of injections.

[0033] Specifically, the button actuation assembly 3 includes a button 31, a button guide block 32, a movable spine 33, a fixed spine 34, and a push block 35. The button 31 is located at the opening 100. The button guide block 32 and the movable spine 33 are both connected to the button 31 and are slidably connected to the top surface of the base plate 2. The fixed spine 34 is fixedly installed on the base plate 2 and is located on both sides of the movable spine 33. The push block 35 is slidably installed on the base plate 2 and is connected to the movable spine 33 and the fixed spine 34 in a transmission connection. When the movable spine 33 moves toward the opening 100, it drives the push block 35 to move toward the opening 100. The movable spine 33 is limited by the fixed spine 34 and does not move backward away from the opening 100. Pressing the button 31 once pushes the push block 35 to drop a single needle from the opening 100. The upper surface of the base plate 2 has a guide rail 21 for mounting the button guide block 32 and the movable spine 33.

[0034] See Figures 4 to 7 The push block 35 includes a push block body 350, an elastic push plate 351, a sliding snap-fit ​​member 254, a fixed snap-fit ​​member 355, and a spine snap-fit ​​member 356. The elastic push plate 351 is installed at the end of the push block body 350 facing the injection. The sliding snap-fit ​​members 254 are symmetrically arranged at the bottom of the push block body 350, and the push block body 350 is slidably connected to the base plate 2 through the sliding snap-fit ​​members 254. The fixed snap-fit ​​members 355 and the spine snap-fit ​​members 356 are rotatably installed at the bottom of the push block body 350. Fixed snap-fit ​​members 355 are installed on both sides of the spine snap-fit ​​members 356. The fixed snap-fit ​​members 355 engage with the fixed spine 34, and the spine snap-fit ​​members 356 engage with the movable spine 33. Both the movable spine 33 and the fixed spine 34 have triangular protrusions facing the same direction. When the movable spine 33 moves inward, the fixed locking piece 355 engages with the fixed spine 34, preventing the push block 35 from moving. When the movable spine 33 moves outward, the push block 35 moves via the spine locking piece 356, and in this direction, the fixed locking piece 355 is no longer limited by the fixed spine 34. Repeatedly pressing button 31 will drive the push block 35 to move continuously towards the opening 100 without reversing. After completing the stroke, the push block 35 should be manually reset when the syringe cartridge is disassembled for replenishment.

[0035] Furthermore, the elastic push plate 351 has several push rods 352 that slide into the push block body 350, and the push rods 352 are connected to the push block body 350 through springs 353 to achieve a buffering function and prevent damage caused by strong squeezing when pushing the injection.

[0036] See Figure 8The end of the upper cover 1 furthest from the opening 100 has a locking end 10, in which a locking structure 4 is installed. When the syringe cartridge is not installed, the locking structure 4 is in a locked state, abutting against the end of the movable spine 33. At this time, the button 31 cannot be pressed, preventing the syringe from falling out. When the syringe cartridge is correctly installed, the locking structure 4 is in an unlocked state, and the movable spine 33 can slide normally. The medication can be retrieved by pressing the button 31. The locking structure 4 is preferably an elastic button extending from the side of the locking end 10. A baffle 41 is installed on the part of the elastic button located inside the locking end 10. Pressing the elastic button changes the position of the baffle 41, realizing the switching between the locking and unlocking states. The locking structure 4 is not limited to the form of an elastic button, but can also be a pressing plate set on the side or rear of the locking end 10, etc.

[0037] See Figure 9 and Figure 10 A limiting rod 22 is installed on the bottom surface of the base plate 2. One end of the limiting rod 22 is rotatably connected to the base plate 2. The limiting rod 22 has a limiting groove 221. The bottom of the button push assembly 3 has several limiting pins 23. The limiting rod 22 is connected to different limiting pins 23 for different needle sizes. The limiting pins 23 are slidably installed in the limiting groove 221. By setting the limiting rod 22, the stroke of the button 31 can be limited for needles of different shapes and sizes, so as to achieve the output of different shapes and sizes one by one. In addition, the stroke of the button 31 is proportional to the stroke of the movable spine 33. By selecting appropriate limiting pins 23 to connect with the limiting rod 22, gaps between the push block 35 and the needle or excessive compression between needles can be prevented, so as to avoid the button being pushed without contact or the needle being damaged.

[0038] See Figure 11 A width-limiting strip 11 is detachably mounted on the bottom of the top surface of the upper cover 1. The width-limiting strip 11 is installed in conjunction with the upper cover slot 111 on the upper cover 1. The upper cover slot 111 has several parallel slots. When the width-limiting strip 11 is installed in different slots, it can accommodate needles of different widths. The width-limiting strip 11 can be selected with different heights to accommodate needles of different shapes and sizes. Depending on the shape of the needle, the width-limiting strip 11 may abut against the end or middle recessed part of the needle.

[0039] See Figure 12 and Figure 13The inner wall of the side panel of the upper cover 1 has several sets of height-limiting grooves. Each set of height-limiting grooves includes several height-limiting grooves 12 of different heights. The end of the height-limiting groove 12 has a height-limiting through hole 121 that penetrates the side panel of the upper cover 1. A set of handles 24 is rotatably mounted on the bottom of the base plate 2. Both ends of the handles 24 have height-limiting parts 241 that penetrate the side of the base plate 2. When the base plate 2 and the upper cover 1 are installed together, the upper cover 1 is inverted, and the height-limiting parts 241 are engaged in the height-limiting grooves 12 and move downward until the height-limiting parts 241 pass through the height-limiting through holes 121, thereby limiting the height of the storage cavity and simultaneously achieving a fixed connection between the base plate 2 and the upper cover 1. The handles 24 are preferably V-shaped handles for easy one-handed operation. The bottom of the base plate 2 has several mounting holes 25 that are horizontally aligned with the height-limiting grooves 12. The height-limiting parts 241 are connected to the base plate 2 through the mounting holes 25.

[0040] When replenishing the injection cartridge, the top cover 1 is inverted, the width limiting strip 11 is adjusted, and then several injections are placed side by side inside the top cover 1. According to the size of the injections, the installation position of the handle 24 is adjusted, and the handle is operated to connect the bottom plate 2 to the top cover 1. After installation, the injection cartridge is flipped over and placed in the corresponding equipment for use. The receiving equipment such as the robotic arm presses button 31 to take out the injections one by one.
