[0030] The present application will be further described in detail below with reference to the drawings.
[0031] The utility model discloses a handheld animal venipuncture device Figures 1-12 , the specific implementation process of the utility model is as follows:
[0032] A handheld animal venipuncture device, comprising a shell 1, a chambering mechanism, a firing mechanism and a needle holding mechanism. The top of the shell 1 is provided with a sliding groove 2 for guiding the sliding of the chambering mechanism. The chambering mechanism comprises a sliding chamber 3, a chambering spring 4, a spring baffle 5 and a striking block 6. The bottom of the sliding chamber 3 is slidably connected with the sliding groove 2 and can slide back and forth in the shell 1. The spring baffle 5 is arranged at one end of the shell 1 and the upper part thereof is located in the sliding chamber 3, for fixing one end of the chambering spring 4. The other end of the chambering spring 4 is connected with the striking block 6, providing striking power for the striking block 6. The striking block 6 is arranged inside the sliding chamber 3 and is in contact with the needle holding mechanism, for pushing the needle holding mechanism to perform puncture when firing.
[0033] The firing mechanism comprises a trigger 7 and a trigger 7 reset assembly. One end of the trigger 7 extends to the outside of the shell 1 for operation by a veterinarian; the other end extends to the top of the shell 1 and is in contact with or separated from the lower end of the striking block 6, for controlling the striking timing of the striking block 6.
[0034] The needle holding mechanism comprises a striking needle sleeve 8, a striking needle 9, a return spring 10, a needle head clamp 11 and a vein compressor 12. The striking needle sleeve 8 is connected with one end of the shell 1 and is in contact with the striking block 6, for fixing and supporting the striking needle 9. The striking needle 9 is arranged inside the striking needle sleeve 8, for puncture operation. The return spring 10 is sleeved outside the striking needle 9, one end of which is connected with the striking needle 9 and the other end is connected with the needle head clamp 11, for resetting the striking needle 9 after puncture. The needle head clamp 11 is arranged at the end of the striking needle sleeve 8 and is screwed with it, for fixing the needle head. The vein compressor 12 is arranged outside the needle head clamp 11, for compressing the vein when puncturing, to improve the success rate of puncture.
[0035] Further, the sliding chamber 3 comprises a sliding part 13 and a striking part 14. The lower end of the sliding part 13 is provided with a sliding piece 15 for sliding cooperation with the sliding groove 2, for guiding the sliding of the sliding chamber 3. The striking part 14 is a circular tube and is arranged at one end of the sliding part 13, for accommodating the striking block 6. The lower end of the striking block 6 extends out of the striking part 14 and is provided with a striking limiting block 25. By pulling the sliding chamber 3, the sliding part 13 moves along the sliding groove 2 while the striking part 14 pushes the striking block 6 to move backward. When the striking limiting block 25 at the lower end of the striking block 6 is in contact with the end of the trigger 7 and is stuck, the chambering operation is realized. At this time, the sliding chamber is released and automatically resets under the action of the chambering spring 4.
[0036] The front part of the shell 1 is provided with a sliding chamber limiting block 17. When the sliding chamber resets, the clamping block 16 at the bottom of the striking part 14 is in contact with the blocking block 18 at the top of the sliding chamber limiting block 17, which can block the sliding chamber 3 from continuing to slide forward, preventing the striking block 6 from overstriking the striking needle sleeve 8 of the needle holding mechanism.
[0037] The spring baffle comprises an end blocking plate 19 and a guide column 20. The end blocking plate 19 is arranged in the outer shell 1 at the end and is used for fixing the guide column 20. The guide column 20 is arranged on the upper end of the end blocking plate 19 and is located in the slide bore 3 and is used for guiding the expansion and contraction of the upper bore spring 4. One end of the upper bore spring 4 is sleeved outside the guide column 20 and the other end is inserted into the inside of the impact block 6 to provide a stable impact force for the impact block 6.
[0038] The trigger 7 reset assembly comprises a reset shell 21 and a reset spring 22. The reset shell 21 is arranged inside the outer shell 1 and is used for accommodating the reset spring 22 and the trigger 7. The reset spring 22 is arranged inside the reset shell 21 and is used for providing a reset power for the trigger 7. The middle part of the trigger 7 is located inside the reset shell 21 and is rotationally connected with the reset shell 21 and can swing forward and backward around the rotation point. One end of the trigger 7 extends to the outside of the outer shell 1 and is used for pressing the trigger 7 and the other end extends to the rear of the outer shell 1 and is in contact with the impact limiting block 25 at the lower end of the impact block 6 and is used for separating from the impact block 6 when the trigger 7 is released, so that the upper bore spring 4 drives the impact block 6 to slide forward and impact the firing pin 9.
[0039] The lower end of the firing pin sleeve 8 is provided with a mounting block 23 which is inserted into the inside of the outer shell 1 and is fixed and is used for fixing the firing pin sleeve 8 on the outer shell 1. The upper end of the firing pin sleeve 8 is in contact with the impact block 6 and is used for pushing the firing pin 9 when the impact block 6 impacts and then firing the needle head to puncture.
[0040] The needle head clamping seat 11 is provided with an elastic clamping groove 24 inside and is used for fixing the needle head. The rear end of the vein compressor 12 is connected with the needle head clamping seat 11 and the front end extends forward and then bends downward to form an arc-shaped compression ring and is used for compressing the vein when puncturing to improve the accuracy of puncturing.
[0041] The above describes the present application and its embodiments, which are not limited. The embodiments shown in the drawings are only one of the embodiments of the present application and the actual structure is not limited.
