For example, since the medicine bottles are all sealed bottles, the resistance is relatively large when drawing the medicine, which is laborious, and the drawing process is slow and wastes time; Judging by the line, the accuracy of the dosage cannot be guaranteed, which will affect the efficacy of the patient's medication. Therefore, how to provide a medical dispensing machine that can automatically extract medicinal liquid and ensure the accuracy, safety, simplicity and reliability of the medicinal liquid has become the research subject of this utility model.
传统抽药方式，医护人员工作比较费力费时，抽药量只能通过目测注射器刻度线来判断，而该款抽药仪器，医护人员只要把药瓶插向针头，在操作面板设置抽药量，按下启动键仪器开始工作，注射器从药瓶抽出设置药量，然后再把药液推出，从而在短时间内实现抽药和排药。The traditional way of pumping medicine is laborious and time-consuming for medical staff, and the amount of medicine drawn can only be judged by visually observing the scale line of the syringe. However, for this medicine pumping instrument, the medical staff only need to insert the medicine bottle to the needle, and set the amount of medicine drawn on the operation panel. Press the start button and the instrument starts to work, the syringe is pulled out from the medicine bottle to set the dose, and then the medicine liquid is pushed out, so that the medicine can be drawn and discharged in a short time.
