When the solvent is not dissolved, the state of the solvent dispenser is as shown in FIG.

When dissolving the drug, the frame 1 can be connected to the card holder and locked by the buckles on both sides of the frame 1. The two

elastic infusion hoses

2, 3 are respectively fixed in position on the two

peristaltic pumps

39, 38, and the two

peristaltic pumps

39, 38 are respectively associated with the two

elastic infusion hoses

2, 3 located at the arch 44. Correspondingly, the two

elastic infusion hoses

peristaltic pumps

39, 38 for roller rolling.

The needle setting device in the automatic solvent dispensing system passes through the needle guide holes 4-7, and then penetrates into the

perforations

12, 13 of the trocar bases 14, 15, and the

puncturing device bases

14, 15 along the

pedestal guide wells

22, 23 outwardly, and the

elastic infusion hoses

2, 3 connected to the trocar bases 14, 15 during the toggle can be dragged and followed by the puncturing bases 14, 15 in the

pedestal wells

22, 23. Movement, the puncturing device 28-31 then pulls out the

pedestal guide wells

22, 23, as shown in FIG.

Then, the

puncturing devices

28, 29, which are connected in parallel at one end, can be inserted into the infusion container 36 of the port downward, and the

puncturing devices

30, 31 connected in parallel at the other end can be inserted into the vial 37 of the port downward. The two

peristaltic pumps

39, 38 simultaneously drive the two

flexible infusion hoses

2, 3, and the solution in the infusion container 36 is quickly pumped into the vial 37, the duration of which is controlled by an intelligent software program. After pumping in, one of the peristaltic pumps 38 (or 39) is reversed, the drive solution is pumped from the vial 37 into the infusion container 36, and the other peristaltic pump 39 (or 38) continues from the infusion container 36 to the Xilin. The solution is pumped into the bottle 37 to form a circulating reflux state between the vial 37 and the infusion container 36, and intense turbulence is formed in the vial 37. In the process of dissolution, continuous drama The solution of the vial solution and the undissolved drug are disturbed, and the concentration of the solution in the limited volume of the vial 37 is continuously and rapidly diluted by the continuous infusion and pumping of the infusion, thereby accelerating the dissolution of the drug. After the drug is completely dissolved, the two

peristaltic pumps

38, 39 completely pump the drug solution in the vial 37 into the infusion container 36. After the pumping is completed, the drug dissolving operation in the vial 37 is completed.

After the solvent dispensing process is completed, the two

trocar bases

14, 15 are dialed back to the bottom of the

pedestal wells

22, 23 by a needle setting device, followed by the puncturing device 28 on the two

trocar bases

14, 15. The -31 is pulled out from the pierced infusion container 36 and the vial 37, respectively, to complete the drug dissolution process.

Example 2: Liquid vial dispensing program

The buckles on both sides of the frame are connected to the card holder and locked, and the two elastic infusion hoses are respectively aligned and fixed on the two peristaltic pumps.

Through the needle setting device, the puncturing device base in the pedestal guiding well placed at both ends of the frame is dialed out, and then the puncturing device on the two puncturing device bases are simultaneously inserted into the insertion port fixed in the automatic solvent dispensing system. Down into the infusion container and vial.

Controlled by intelligent software program, the peristaltic pump is used to drive the elastic infusion hose connected with the short puncture of the vial end, and the liquid in the vial is directly pumped into the infusion container; the other channel provides the air pressure balance during the operation. So that the liquid is easily and quickly extracted. After the pumping is completed, the drug preparation operation in the vial is over.

The puncturing device base is turned back by the needle setting device, and the puncturing devices on the two puncturing device bases are respectively pulled out from the infusion container and the vial bottle, and retracted into the pedestal guide groove well to complete the dispensing operation process.

The above two specific embodiments show that the dissolving process can perform the operation of rapidly dissolving the medicine and can realize automation, greatly improve the efficiency of dissolving the medicine, and greatly reduce the labor intensity of the medical staff; In the middle, the medical staff does not need to contact, no need to repeatedly puncture, minimize the spillage and volatilization of the drug during the dispensing process, effectively reduce the harm of the drug to the medical staff during the process of dissolving the drug, and effectively reduce the rubber plug particles in the process of dissolving the drug. The pollution of foreign particles and microbes minimizes the exposure of drugs and secondary pollution of drugs, improves the safety of infusion, and helps protect the health of medical personnel and patients.

The solvent dispenser of this embodiment has the following beneficial effects:

The solvent dispenser is designed to be easily installed in an automatic solvent dispensing system for rapid dissolution of formulated drugs for improved efficiency;

The puncturing device on the base of the two puncturing devices is inserted into the infusion container and the vial at the same time or separately, thereby forming a closed system of two-channel internal communication, which does not need to repeatedly puncture during the process of dissolving the formulated medicine, thereby greatly reducing the medical personnel's Labor intensity; and medical personnel do not need to contact, no need to repeatedly puncture, effectively reduce the harm of drugs to medical staff during the process of dissolving drugs, reduce drug exposure and secondary pollution of drugs, improve the safety of infusion, and help protect medical staff and Patient's health;

Through the controllable two-way driving of two peristaltic pumps, it provides dual-dynamic two-way fluid (such as liquid, gas, liquid-solid mixture) during the dissolution of the drug. In the process of dissolving the drug, the fluid is in the infusion container, the vial and Different flow modes can be formed between the two channels (such as double-directional, double reverse, inner circulation), which can form intense turbulence in the vial, so that the drug in the vial can be quickly dissolved and can pass through the inner circulation. The flow mode balances the air pressure in the vial and the infusion container, avoiding the difficulty of the injection of the liquid medicine due to the imbalance of the air pressure during the manual operation and the single-channel operation, thereby rapidly dissolving and transferring the liquid to the infusion container, so that the dissolution efficiency is high. The effect of dissolving the drug is good.

Embodiment 2:
