Medical dispensing machine

Abstract

Provided is a medical dispensing machine. The medical dispensing machine is characterized in that the medical dispensing machine comprises a fixing frame, a driving mechanism, a sliding block, a guide rail, a syringe, a medicine pumping pipeline and a medicine discharging pipeline; the syringe is composed of a push rod and a needle cylinder which is fixed and supported on the fixing frame, and the push rod is fixedly connected with the sliding block; the sliding block can be driven by the driving mechanism to do rectilinear motion in the length direction of the syringe, the sliding block is located on the guide rail, and the guide rail is fixed relative to the fixing frame; a liquid outlet is formed in the head part of the needle cylinder, one end of the medicine pumping pipeline is connected with the liquid outlet, the other end of the medicine pumping pipeline is connected with a medicine bottle, the medicine pumping pipeline is internally provided with a first one-way valve, and the conducting direction of the first one-way valve is from the medicine bottle to the needle cylinder; one end of the medicine discharging pipe is connected with the liquid outlet, the other end of the medicine discharging pipe is connected with a liquid collector, the medicine discharging pipe is provided with a second one-way valve, and the conducting direction of the second one-way valve is from the needle cylinder to the liquid collector. The medical dispensing machine has higher accuracy, and the safety, simplicity and reliability of medicine pumping work of medial staff are improved.

Description

Technical field [0001] The invention relates to the field of medical devices, in particular to a medical dispensing machine for automatically extracting liquid medicine. Background technique [0002] In clinical practice, when using liquid medicine on patients, medical staff need to draw liquid medicine quantitatively in advance to control the amount of medicine used. The traditional way of extracting liquid medicine is manual extraction from the medicine bottle. However, this method has many shortcomings. For example, because the medicine bottles are all sealed bottles, the resistance when pumping the medicine is relatively large, it is more laborious, and the pumping process is slow and time-consuming; the amount of medicine can only be measured by the visual syringe scale when pumping the medicine. It is impossible to guarantee the accuracy of the dosage, which will affect the efficacy of the patient’s medication. Therefore, how to provide a medical dispensing machine capable...
