The height change of the display float 14 can be detected through the liquid level displacement sensor 15.

[0032] The top of the display support seat 3 is connected to a conversion platform 4, which is connected to a sliding seat 34 through a conversion component. The sliding seat 34 is provided with a mounting plate 5, and the mounting plate 5 is rotatably connected to the sliding seat 34;

A sliding opening is opened on the conversion platform 4, and slide rails slidably connected to the sliding opening are arranged on both sides of the sliding seat 34. The output end of the switching push rod 16 is fixedly connected to the side wall of the sliding seat 34.

[0034] The advantage of adopting the above structure is that the position of the mounting plate 5 can be changed by switching the push rod 16, that is, the vial of medicine and the infusion bottle can be switched, thereby satisfying the automatic dispensing use of the injection needle set on the support assembly.

[0035] A central installation groove 6 for installing an infusion bottle is provided at the center of the installation plate 5, and a plurality of shaking components for installing a syringe bottle are provided on the installation plate 5 around the central installation groove 6;

[0036] Furthermore, the shaking assembly includes a rotating disk 17 rotatably disposed on the mounting disk 5 , the rotating disk 17 is connected to an assembling ball 18 via a limiter, and an assembling port 19 for mounting a vial is provided on the assembling ball 18 .

[0037] The vial is installed in the assembly opening 19, and the top of the vial is effectively limited by a limiting cap 23 provided on the fastening cover 7 to ensure the installation effect.

[0038] Furthermore, the limiting member includes a connection port opened on the rotating disk 17, the inner wall of the connection port is fixedly connected to the limiting block 28, and the assembly ball 18 is provided with an arc-shaped opening for the limiting block 28 to move, so that the assembly ball 18 can swing left and right in the connection port on the rotating disk 17.

[0039] A rotating gear ring 20 is fixedly connected to the rotating disk 17, a linkage gear ring 21 meshing with the rotating gear ring 20 is rotatably connected to the mounting disk 5, a direct drive motor is arranged on the sliding seat 34, and a direct drive gear 22 meshing with the linkage gear ring 21 is fixedly connected to the output end of the direct drive motor.

[0040] Furthermore, the inner wall of the fastening cover body 7 is connected to the limiting cap cover 23 through a sliding block, the inner wall of the fastening cover body 7 is fixedly connected with an inner support ring 24, the inner support ring 24 is connected with a wave contact block 25 through a spring sliding block, the top of the linkage gear ring 21 is fixedly connected with a wave contact ring 26 that contacts the wave contact block 25, and the inner wall of the fastening cover body 7 is slidably provided with a pushing block 27 that contacts the wave contact block 25.

[0041] It is worth noting that when the linkage gear ring 21 is driven to rotate, the wave resistance ring 26 on its top will generate a force on the wave resistance block 25, causing it to move left and right under the action of the resistance force, thereby driving the push block 27 to move, thereby realizing the horizontal movement of the limit cap 23, thereby fully shaking the vial of medicine in the assembly ball 18, thereby meeting the mixing requirements of the powder medicine.

[0042] The conversion platform 4 is detachably mounted with a fastening cover 7 via a threaded ring, and a central sleeve 8 for fastening the infusion bottle is arranged on the fastening cover 7;

[0043] A weighing liquid level piston 9 is arranged inside the main U-shaped connecting tube 2, and a supporting assembly for installing a liquid injection syringe is arranged on the weighing liquid level piston 9. Furthermore, the supporting assembly includes an outer half tube body 29, a locking arc seat 30 is arranged on the top of the outer half tube body 29, a fixed block is arranged on the back of the outer half tube body 29, and a pneumatic propulsion pump 31 is arranged on the fixed block. The output end of the pneumatic propulsion pump 31 is connected to a propulsion block 32, and the propulsion block 32 is connected to a propulsion arc seat 33 through a vertical sliding member.

A one-way air port is opened on the one-way drive piston 12, and a spring blocking ball is arranged on the inner wall of the one-way air port.

[0045] The setting of the one-way driving piston 12 can push the liquid in the main U-shaped connecting tube 2 to flow during the upward movement, and will not push the liquid to flow during the downward movement, that is, the spring blocking ball can achieve the effect of liquid flow when moving downward.

[0046] When the present invention is used, the vial of medicine is placed in the assembly port 19 of the assembly ball 18, the infusion bottle is placed on the installation center groove 6, and the medicine is squeezed by tightening the cover body 7 so that it can be sealed and stored on the installation plate 5;

[0047] The needle tube is mounted on the supporting assembly, the locking arc seat 30 is clamped with the end of the needle tube, and the piston pushing end of the needle tube is mounted on the pushing arc seat 33. In this process, the weight of the needle tube is supported by the weighing liquid level piston 9, and then transmitted to the liquid level display device through the main U-shaped connecting pipe 2 to display the weight;

[0048] The position of the mounting plate 5 is controlled by the switching assembly to change the position of the syringe bottle medicine and the infusion bottle. When extracting and injecting liquid, the electric push rod 11 controls the one-way driving piston 12 to move, so that the needle tube on the supporting assembly supporting the weighing liquid level piston 9 is pushed upward, so that the needle tip is inserted into the medicine bottle. When extracting liquid, the pneumatic propulsion pump 31 controls the propulsion arc seat 33 to move the syringe piston, so that the medicine is extracted from the syringe bottle and then injected into the infusion bottle. In this process, the injection amount of the medicine can be determined at all times through the changes in the main U-shaped connecting tube 2, thereby ensuring the precise control of the quality of the medicine. The whole process is operated in a sterile environment through mechanical equipment to prevent the occurrence of medicine contamination caused by human operation.
