[0037] Push-pull assembly 24, mounted on bracket 23, is used to connect with the handle of syringe body 1; and

[0038] The snap-fit ​​assembly 25 is installed at the bottom of the upper grip 22 and is used to connect and fix the lower grip 21 and the upper grip 22.

[0039] The lower grip 21 and the upper grip 22 can be quickly connected through the snap-fit ​​assembly 25, and the lower grip 21 and the upper grip 22 can be easily separated.

[0040] The lower grip 21 has four slots 211 at the top, and the upper grip 22 has docking slots 212 on the top right side of the lower grip 21 and the bottom right side of the upper grip 22. The slots 211 are used to cooperate with the buckle assembly 25, and the docking slots 212 are used to dock with the protrusions on the syringe body 1 and restrict the position of the syringe body 1.

[0041] Both the lower grip 21 and the upper grip 22 have arc-shaped grooves at their centers, which are adapted to the syringe body 1.

[0042] A control switch 221 is installed on the upper grip 22. Two brackets 23 are fixedly connected to the right side of the upper grip 22. The bottom of the brackets 23 is fixedly connected to the right side of the lower grip 21. An electric push rod 231 is fixedly connected to the right side of the brackets 23. The control switch 221 is used to control the start and stop of the electric push rod 231.

[0043] The push-pull assembly 24 is used to connect to the output end of the electric push rod 231, and the electric push rod 231 is used to drive the push-pull assembly 24 to move.

[0044] The push-pull assembly 24 includes a push block 241 fixedly connected to the output end of the electric push rod 231. The push block 241 has a slot 242 inside. The handle on the piston rod of the syringe body 1 is inserted into the slot 242 on the push block 241. After the syringe body 1 is installed on the lower handle 21 and the upper handle 22, the electric push rod 231 is activated by pressing the control switch 221. The electric push rod 231 is activated to drive the push block 241 to push or pull, so that the piston rod of the syringe body 1 is pushed or pulled, and medication can be drawn or discharged. This method effectively assists medical staff in preparing solutions, reduces labor, and effectively protects the hands.

[0045] The buckle assembly 25 includes several locking blocks 251 fixedly connected to the bottom of the upper grip 22. The locking blocks 251 are arranged in pairs. Two springs 252 are fixedly connected to the side of each pair of locking blocks 251 that are close to each other. When the upper grip 22 is connected to the lower grip 21, the locking blocks 251 will be inserted into the slots 211 and reset by the elastic force of the springs 252 and the elastic force of the locking blocks 251 themselves. The lower grip 21 and the upper grip 22 are connected and fixed by the protrusion on the locking block 251 cooperating with the slot 211. This method can quickly complete the connection and fixation, and the operation is simple and convenient.

At the same time, insert the handle of the piston rod on the syringe body 1 into the push block 241. After placement, dock the upper handle 22 with the lower handle 21. The locking block 251 will then be inserted into the locking groove 211. When the locking block 251 contacts the lower handle 21, the locking block 251 will be squeezed by the triangular protrusion on the locking block 251. At this time, the spring 252 will also be squeezed, so that the protrusion on the locking block 251 can smoothly enter the locking groove 211. Then, the spring 252 and the locking block 251 will reset by the elasticity of the spring 252 and the elasticity of the locking block 251 itself. The lower handle 21 and the upper handle 22 are docked and fixed by the cooperation of the protrusion on the locking block 251 and the locking groove 211. The connecting strap 222 is used to connect the lower handle 21 and the upper handle 22 to prevent them from being lost.

[0050] After docking is complete, the user holds the lower handle 21 and the upper handle 22, and controls the electric plunger 231 by pressing the control switch 221. When medication needs to be drawn, the syringe body 1 is first inserted into the medication, and then the electric plunger 231 is activated to drive the push block 241 to pull, which in turn pulls the piston rod of the syringe body 1 to draw the medication. When the medication in the syringe body 1 needs to be added to other medications, the syringe body 1 is inserted into the medication, and then the electric plunger 231 is activated to drive the push block 241 to move in the opposite direction, which pushes the piston rod on the syringe body 1 to push out the medication. This method effectively assists medical staff in preparing medications.
