Embodiment

[0032] The instrumentation with ten injector modules has a footprint of approximately 2.8m x 2.0m and a height of approximately 2.5m. The station staff puts the infusion bag 2 on the empty tray. When placing it, just press the short cylindrical part of the infusion bag used for dispensing into the clip on the tray, the short cylindrical part of the infusion bag will press down the raised slider in the clip, and the clip will automatically close, and the infusion bag will be clamped tight. The staff then place the vials on the tray according to the name and quantity of the required vials 37. In order to adapt to the different specifications of the vials, there are stepped pits on the tray, and the vials with the smallest diameter are placed at the bottom. The largest vial is placed on top. There are keyways on both sides of the tray, long keys on both sides of the guide rail of the dispensing station, and there is a gap between the key and the keyway. In order to ensure that...

Abstract

The invention relates to an automatic medicine dispensing device based on macro/micro driving and precise liquid medicine control and belongs to the field of medical equipment. The automatic medicine dispensing device is characterized in that a macro/micro driving injector movement unit and a grating scale linear displacement sensor form closed loop feedback control, the position of an injector inserted into a medicine bag and the position of the injector inserted into a penicillin bottle are precisely controlled, and a servo motor is decelerated by a worm and gear to drive a rotary block to realize a 90-degree turning action of the injector; a penicillin bottle manipulator-grabbing and moving unit adopts macro/micro combined dual driving to control a lead screw to move, so that the penicillin bottle is accurately grabbed from a conveying belt tray to a spring cup in a designated position, and a disinfection nozzle is configured for disinfecting a penicillin bottle opening; a penicillin bottle oscillation unit is driven by a motor to perform oscillation at specific amplitude and specific frequency after a medicine is injected into the penicillin bottle, and the medicine is enabled to be dissolved sufficiently. The automatic medicine dispensing device realizes rapid and precise medicine dispensing, sufficiently utilizes the medicine, avoids waste, can relieve pressure of a nurse, reduces medicine dispensing errors and has great realistic significance and practical value.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to the field of infusion dispensing equipment, in particular to an automatic dispensing device based on macro and micro drives and precise control of medicinal liquid. Background technique [0002] At present, the infusion dispensing in most hospitals in China is manually operated by nurses, that is, holding the syringe to suck the liquid medicine from the medicine bag, and then injecting it into the cillin bottle that the medicine powder is housed. This is not only time-consuming and labor-intensive, but also prone to errors. Moreover, there is a shortage of nursing staff in our country, and the work pressure is high. Manually preparing intravenous infusion is an important daily work for nurses, and it is also an important method for hospitalization of patients. Timely and accurate drug administration is an important part of patient evaluation, nursing and medical work. [0003] R...
