Abstract

The present invention discloses one kind of automatic pumping and injecting device for clinical medicine compounding. The automatic pumping and injecting device includes one frame, a pumping and injecting needle cylinder-piston mechanism, a transmission mechanism, a power set and a controlling mechanism connected together. The present invention is used in clinical medicine compounding, and has high efficiency and less medicine contaminating possibility.

Description

1. Technical field [0001] The present invention relates to the technical field of medical auxiliary devices, and more specifically, relates to a device for clinically preparing medicaments. 2. Background technology [0002] Most departments of the hospital need to prepare a large amount of medicine every day, especially in large and medium-sized hospitals, the dosage of medicine prepared every day is very large. The medicament preparation in the hospital at present, no matter how much the medicament preparation amount is, all is to draw injection preparation by manually using the syringe. When the dose of the prepared medicine is relatively large, the labor intensity of the preparation personnel is high, the degree of automation is low, and the mutual contamination between the personnel and the medicine is likely to be caused during the preparation process of the medicine. The automatic injection device for clinical medicament preparation disclosed by the present invention ...
