Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a dispensing machine.
Background
The existing medicine package mainly comprises a penicillin bottle and an ampoule bottle.
A penicillin bottle (also known as borosilicate glass or soda-lime glass tube (molded) injection bottle) is a small bottle with a sealed rubber plug, the bottle mouth is slightly thicker than the bottle neck and slightly thinner than the bottle body, and the penicillin bottle is generally used for packaging medicines such as vaccines, biological preparations, powder injections, freeze-drying and the like. If the injection is a liquid agent, the operation is simpler, and only the needle is inserted into the penicillin bottle and the agent is pumped out, so that the injection can be injected into the infusion bag; if the powder injection is the powder injection, a solution needs to be injected into a Xilin bottle to dissolve the powder injection, and the operation steps are that the liquid medicine is extracted from the infusion bag, the needle head of the needle cylinder is inserted into the Xilin bottle to inject the liquid medicine into the Xilin bottle, the Xilin bottle is shaken manually to dissolve the powder and the liquid medicine in the bottle, then the needle head is inserted into the Xilin bottle to stand the Xilin bottle upside down, and the liquid medicine in the Xilin bottle is sucked out; and (4) injecting the liquid medicine in the sucked syringe into the infusion bag, and pulling out the needle head to finally complete the transferring and dispensing of the medicament in the penicillin bottle.

The other end of the pumping container 33, which is away from the outlet, is provided with a pumping end 332, and the pumping end 332 reciprocates in the cavity 331 of the pumping container 33 to pump the liquid medicine into or out of the cavity 331. The first infusion tube 311 and the second infusion tube 312 are respectively positioned in the positioning slot 42 between the eccentric structure 34 and the positioning seat 41, the eccentric structure 34 is rotatably connected with the base 40, when the eccentric structure 34 rotates, the first eccentric block 341 is close to the positioning seat 41, so that the width of the positioning slot 42 is narrowed, and the first infusion tube 311 or the second infusion tube 312 positioned in the positioning slot 42 is pressed, meanwhile, the second eccentric block 342 drives the suction end 332 of the suction container 33 to move, so that the suction container 33 performs suction movement, because the eccentric modes of the first eccentric block 341 and the second eccentric block 342 are the same, when the first infusion tube 311 or the second infusion tube 312 is pressed by the first eccentric block 341, the suction container 33 is driven by the second eccentric block 342 to perform suction movement; when the first eccentric block 341 does not press the first infusion tube 311 and the second infusion tube 312, the second eccentric block 342 brings the suction end 332 to be at the bottommost end or the topmost end of the suction container 33, and the suction container 33 is horizontally placed in the drawing, so that the bottommost end can be understood as the end closest to the eccentric structure 34, and the topmost end can be understood as the end farthest from the eccentric structure 34.

Secondly, when the medicine is powder, the medicine liquid needs to be added to completely dissolve the powder before the medicine liquid can be input into the infusion container 23, at this time, the medicine liquid in the infusion container 23 needs to be input into the medicine bottle 11, and after the powder is completely dissolved, the medicine liquid in the medicine bottle 11 is sucked into the infusion container 23. The work flow of the eccentric structure 34 at this time is that the eccentric structure 34 rotates forward, when the first eccentric block 341 presses the second infusion tube 312, the second infusion tube 312 is conducted, the suction container 33 is in a liquid suction state, the medicine is sucked into the containing cavity 331 from the infusion container 23, then the first eccentric block 341 and the second eccentric block 342 continue to rotate, the suction end 332 of the suction container 33 is close to the topmost end, at this time, the first eccentric block 341 does not press the first infusion tube 311 and the second infusion tube 312, then the first eccentric block 341 and the second eccentric block 342 continue to rotate, the suction end 332 approaches to the eccentric structure 34, the suction container 33 is in a liquid squeezing state, at this time, the first eccentric block 341 gradually presses the first infusion tube 311, so that the medicine liquid in the containing cavity 331 enters the second infusion tube 312, and then enters the medicine bottle 11; the eccentric structure 34 continuously rotates until the liquid medicine in the medicine bottle 11 is enough to dissolve the powder, and then the medicine bottle 11 is shaken to fully dissolve the powder and uniformly mix the liquid medicine; then the eccentric structure 34 is reversed, when the first eccentric block 341 extrudes the first infusion tube 311, the second infusion tube 312 is conducted, the suction container 33 is in a liquid suction state, the medicine is sucked into the containing cavity 331 from the medicine bottle 11, then the first eccentric block 341 and the second eccentric block 342 continue to rotate, the suction end 332 of the suction container 33 is close to the topmost end, at this time, the first eccentric block 341 does not extrude the first infusion tube 311 and the second infusion tube 312, then the first eccentric block 341 and the second eccentric block 342 continue to rotate, the suction end 332 is close to the eccentric structure 34, the suction container 33 is in a liquid squeezing state, at this time, the first eccentric block 341 gradually extrudes the second infusion tube 312, so that the medicine liquid in the containing cavity 331 enters the first infusion tube 311 and then enters the infusion container 23; the eccentric structure 34 continues to rotate until the medicament in the vial 11 is completely transferred to the infusion container 23.
Thirdly, if one part of the medicine is powder and the other part is liquid, the flow stopping mechanism 50 is needed to clamp the third infusion tube 313 communicated with the medicine bottle 11 filled with the liquid medicine, so that the powder is firstly dissolved and converted into the liquid medicine and then the third infusion tube 313 communicated with the medicine bottle 11 filled with the liquid medicine is conducted, the liquid medicines of a plurality of medicine bottles 11 are extracted, the working efficiency is improved, repeated needle insertion is avoided, and microbial or dust pollution is avoided. The manner of transferring and sucking the powder into the liquid medicament and the liquid medicament after dissolving the powder is as above, and is not described herein again.
