Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1

[0029] To address the technical problems in the background art, the following booster device for an electro-injector is provided:

[0030] Combination Figures 1-4As shown, the present invention provides a booster device for an electronic injector, comprising an injector body 1 and a drive wall 2. The injector body 1 includes an injection cylinder 11 with one side open. An injection end is provided on the side of the injection cylinder 11 away from its opening. An injection needle 12 is installed on the injection cylinder 11 at its injection end and communicates with its interior. A piston plate 13 is slidably and sealingly connected to the inner wall of the injection cylinder 11. A push rod 14 extending to the outside of the injection cylinder 11 is fixedly installed on the side of the piston plate 13 away from the injection needle 12. A pusher plate 15 is fixed to one end of the push rod 14 extending to the outside of the syringe 11. During use, when injecting sodium hyaluronate liquid into the syringe 11, the injection end of the syringe 11 is inserted into the sodium hyaluronate liquid storage bottle. Pulling the push plate 15 causes the piston plate 13 to move towards the opening end of the syringe 11 via the push rod 14, thus creating a negative pressure inside the syringe 11 and drawing the sodium hyaluronate liquid into it, achieving the effect of injecting sodium hyaluronate liquid into the syringe 11. The drive wall 2 has a rectangular cross-section. Two sliders 21 are slidably mounted on the bottom of the moving wall 2 along its width. Each slider 21 has a V-shaped clamping plate 22 fixedly mounted on its bottom, and the two clamping plates 22 are symmetrically arranged. When replacing the syringe 11, the syringe 11 is positioned within the V-shaped groove on one side of the two clamping plates 22, improving the clamping effect on the syringe 11 and making it suitable for syringes 11 of different sizes. The syringes 11 are located on opposite sides of the two clamping plates 22. An adjustment mechanism acting on the two sliders 21 is installed on the driving wall 2. Component 3 is used to make the two sliders 21 slide symmetrically or stop sliding on the drive wall 2, so that the two clamping plates 22 clamp and position or cancel the positioning of the injection cylinder 11. The drive wall 2 is equipped with a drive mechanism 4 that acts on the push plate 15, which is used to make the push plate 15 move along the push rod 14, so that the piston plate 13 slides within the injection cylinder 11 to achieve driving. Through the design of the drive mechanism 4, it is easy to move the push rod 14 through the push plate 15, so that the piston plate 13 slides within the injection cylinder 11 to achieve the boosting effect.

[0031] By designing the slider 21, clamping plate 22, and adjusting member 3, when installing the syringe body 1, the syringe barrel 11 is positioned between the opposite sides of the two clamping plates 22. The two sliders 21 slide in opposite directions on the drive wall 2 via the adjusting member 3, moving closer to each other, so that the two clamping plates 22 clamp and position the syringe barrel 11, thus completing the positioning of the syringe body 1. Conversely, by sliding in opposite directions on the drive wall 2 via the adjusting member 3, the two sliders 21 move away from each other, thus canceling the clamping and positioning of the syringe barrel 11 by the two clamping plates 22, allowing the syringe body 1 to be disassembled and replaced. The operation is simple, thus facilitating the disassembly and replacement of the syringe body 1.

[0032] Example 2

[0033] like Figures 1-4As shown, based on the above embodiments, this embodiment further provides the following:

[0034] In this embodiment, the adjusting member 3 includes a bidirectional threaded rod 31 that is horizontally rotatably mounted on the drive wall 2, and the bidirectional threaded rod 31 is threadedly connected to both sliders 21. In use, a force is applied to the bidirectional threaded rod 31 to make it rotate on the drive wall 2, thereby causing the two sliders 21 to slide in opposite directions on the drive wall 2, moving away from or closer to each other. The operation is simple. Since the bidirectional threaded rod 31 is threadedly connected to both sliders 21 and has self-locking properties, the positions of the two sliders 21 can be fixed without rotating the bidirectional threaded rod 31, which is convenient for use.

[0035] In this embodiment, the driving mechanism 4 includes a sliding block 41. A sliding groove is provided at the bottom of the driving wall 2 on the side of the two sliders 21 away from the injection needle 12. The sliding block 41 is slidably installed in the sliding groove along the length of the driving wall 2. A locking plate 42 that can engage with the push plate 15 is fixedly installed at the bottom of the sliding block 41. A horizontal driving rod 43 is rotatably installed on the driving wall 2. One end of the driving rod 43 extends into the sliding groove and is threadedly connected to the sliding block 41. A motor 44 for driving the driving rod 43 to rotate is fixedly installed on the driving wall 2. In use, the motor 44 is controlled to work. The output shaft of the motor 44 rotates and drives the driving rod 43 to rotate, thereby causing the sliding block 41 to slide and move in the sliding groove, thereby causing the locking plate 42 to slide and move. The push plate 15 drives the push rod 14 to cause the piston plate 13 to slide and move in the injection cylinder 11, which is convenient for control.

[0036] In this embodiment, the bottom of the snap-fit ​​plate 42 is provided with a slot 421, and the push plate 15 can be inserted into the slot 421 and snap-fit ​​with the snap-fit ​​plate 42. The snap-fit ​​plate 42 is provided with a snap-fit ​​groove 422 that communicates with the inside of the slot 421 on the side of the slot 421 near the syringe 11. When the push plate 15 is inserted into the slot 421, the push rod 14 is inserted into the snap-fit ​​groove 422. In use, the syringe 11 is placed on the opposite side of the two clamping plates 22. When the syringe 11 is clamped and positioned by the two clamping plates 22, the push plate 15 is inserted into the slot 421 and the push rod 14 is inserted into the snap-fit ​​groove 422, so that the push plate 15 and the snap-fit ​​plate 42 can be snap-fitted together. The operation is simple.

[0037] Example 3

[0038] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

[0039] In this embodiment, rubber pads 221 are fixedly installed on the side of the two clamping plates 22 that are close to each other. By designing the rubber pads 221, when the two clamping plates 22 clamp and fix the injection cylinder 11, the two rubber pads 221 contact the injection cylinder 11, thereby increasing the friction between the two clamping plates 22 and the injection cylinder 11, thereby increasing the clamping and fixing effect on the injection cylinder 11.

[0040] In this embodiment, a receiving groove 23 is provided at one end of the drive wall 2 near the motor 44 and above the sliding groove. A storage battery 24 is placed on the drive wall 2 and inside the receiving groove 23 to provide power to the motor 44. A sealing shell 25 is fixedly installed on the drive wall 2 and sleeved on the outside of the motor 44 by screws. The sealing shell 25 seals the opening end of the receiving groove 23. By setting the sealing shell 25, the opening end of the receiving groove 23 is sealed. Furthermore, the sealing shell 25 is sleeved on the outside of the motor 44, thereby achieving the effect of protecting the motor 44.

[0041] In this embodiment, a liquid storage tube 5 is fixedly installed on the top of the driving wall 2. One end of the liquid storage tube 5 near the injection needle 12 extends to the outside of the driving wall 2, and an outlet tube 51 communicating with its interior is fixedly installed at the bottom of the liquid storage tube 5 on the outside of the driving wall 2. The other end of the liquid storage tube 5 is fixedly installed with an inlet tube 52 communicating with its interior. One end of the syringe 11 near the injection needle 12 extends to the outside of the driving wall 2, and a top end of the syringe 11 extending to the outside of the driving wall 2 is fixedly installed with an inlet tube 52 communicating with its interior. The connecting pipe 111 is connected to the syringe 11. It is worth noting that when the piston plate 13 is in contact with the inner wall of the syringe 11 away from its opening, the piston plate 13 blocks the connecting pipe 111. The end of the outlet pipe 51 can be inserted into the connecting pipe 111, and a threaded sleeve 511 that can be threadedly connected to the connecting pipe 111 is movably fitted on the outer side of the outlet pipe 51. A one-way valve 512 is fixedly installed on the inner wall of the end of the outlet pipe 51 away from the storage pipe 5. It is worth noting that the flow direction of the one-way valve 512 is along the outlet pipe 51 away from the storage pipe 5. The liquid pipe 5 has unidirectional flow. In use, sodium hyaluronate liquid is filled into the reservoir pipe 5 through the inlet pipe 52, and the injection end of the syringe 11 is sealed. The motor 44 is then activated, causing the piston plate 13 to move towards the opening of the syringe 11, creating a negative pressure inside the syringe 11. At this time, the one-way valve 512 opens, allowing the sodium hyaluronate liquid inside the reservoir pipe 5 to flow into the syringe 11 through the outlet pipe 51. When injecting the sodium hyaluronate liquid into the syringe 11, the motor 44 is activated. When the machine 44 is working, the piston plate 13 is moved away from the opening end of the syringe 11, so that the sodium hyaluronate liquid in the syringe 11 can be discharged through the injection end of the syringe 11 to achieve the injection effect. At this time, the one-way valve 512 is in the closed state. When replacing the syringe body 1, rotate the threaded sleeve 511 to separate it from the connecting tube 111, so that the liquid outlet tube 51 can be pulled out from the connecting tube 111. The liquid outlet tube 51 and the syringe 11 can be disassembled and separated, so that the syringe body 1 can be disassembled and replaced. The operation is simple.
