Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a solvent dispensing device. Background Art

[0002] Solvent is a liquid that can dissolve gas, solid, and liquid to form a uniform mixture. Solvents are often needed in medical preparations. Some drugs need to be diluted and dissolved with solvents. A certain amount of drug is injected into a certain amount of solvent to complete the preparation.

[0003] Since the solvent content in the solvent bag is too much, it is usually necessary to extract part of the solvent before injecting the medicine. However, the existing dispensing device usually only has a steel needle and a peristaltic pump, and it is necessary to manually or separately use equipment to extract the excess solvent in the solvent bag, and then inject the medicine into the solvent bag after sucking it out. The next solvent bag can only be dispensed after the dispensing of one solvent bag is completed. The degree of automation is low, the operation is complicated, and it is time-consuming and labor-intensive. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the existing solvent dispensing device, such as low automation, complex operation, and time-consuming and labor-intensive operation.

[0005] In order to solve the above technical problems, the present invention provides a solvent dispensing device, comprising:

[0006] A rotating support, on which a loading station, a prescription scanning station, a solvent extraction station, a drug injection station and a finished product unloading station are arranged in sequence along the rotating direction of the rotating support;

[0007] A plurality of solvent bag bodies are fixed to the loading station one by one, so as to pass through each station in turn to complete the dispensing under the drive of the rotary bracket, and leave the rotary bracket through the finished product unloading station.

[0008] The swivel bracket comprises a rotating frame and a fixed frame, the rotating frame is rotatably connected to the inside of the fixed frame, a plurality of slots are provided on the rotating frame corresponding to each workstation, and the solvent bag body is clamped in the slots through a solvent bag clamp.

[0009] The fixed frame is provided with a first opening for loading and a second opening for unloading corresponding to the loading station and the finished product unloading station.

[0010] The fixing frame is provided with a suction mechanism corresponding to the solvent extraction station, and the suction mechanism reciprocates toward the solvent bag body located at the solvent extraction station to extract the solvent in the solvent bag body or to separate from the solvent bag body.

[0011] The suction mechanism includes a movable needle holder, a suction needle disposed on the movable needle holder, and a first peristaltic pump connected to the suction needle. When the suction mechanism moves toward the solvent bag body, the movable needle holder drives the suction needle to be inserted into the solvent bag body to extract the solvent.

[0012] The solvent bag clamp is provided with a clamp QR code, and the fixed frame is provided with a second code reader corresponding to the loading station. The second code reader reads the clamp QR code and sends information to the controller. The controller controls the movable needle holder to drive the needle to move to the corresponding position, and inserts the solvent bag body into the solvent bag body after the solvent bag body moves to the solvent extraction station.

[0013] The fixing frame is provided with a pair of first code readers corresponding to the prescription scanning station, and the pair of first code readers are arranged corresponding to the two opposite extension surfaces of the solvent bag body at the station to read and save the prescription on the pair of extension surfaces of the solvent bag body.

[0014] The fixing frame is provided with a filling mechanism corresponding to the drug injection station, and the filling mechanism reciprocates toward the solvent bag body located at the drug injection station to inject the drug into the solvent bag body or to separate the drug from the solvent bag body.

[0015] The filling mechanism includes a filling needle holder, a filling needle arranged on the filling needle holder, and a second peristaltic pump connected to the filling needle. When the filling mechanism moves toward the solvent in the solvent bag body, the filling needle holder drives the filling needle to be inserted into the solvent bag body to inject the medicine.
