Problems solved by technology

However, it does not detect whether there is an empty bottle, so that misoperation occurs, resulting in waste of eye drops
In addition, eye drops need to pass through a section of delivery pipe from two-stage sterile filtration to dispensing, resulting in a pressure difference between the sterile filter and the dispensing machine, which directly causes the problem of unstable dispensing and measurement of the dispensing machine due to the pressure difference.

Embodiment Construction

[0015] Such as figure 1 As shown, it is a module block diagram of an eye drop dispensing control system of the present invention, which includes a control processing circuit, an order execution circuit, a photoelectric switch and a dispensing flowmeter. Among them, multiple photoelectric switches are set at each bottle-input dial on the filling machine to detect whether there is a bottle shortage. A dispensing flowmeter is installed on each dispensing pipe on the dispensing machine to measure the flow of eye drops. In addition, the subpackage flowmeter and the optical switch are connected to the input end of the control processing circuit, and the command execution circuit is connected to the output end of the control processing circuit.

[0016] The system also includes a buffer tank arranged on the liquid inlet pipe of the filling machine, a solenoid valve is arranged at the liquid inlet of the buffer tank, and the buffer tank is arranged on an electronic scale. The electr...

Abstract

The invention discloses an eye drop sub-packaging control system, comprising a control and processing circuit, a command executing circuit, a buffer tank, a photoelectric switch and a sub-packaging flowmeter, wherein a solenoid valve is arranged at a liquid inlet of the buffer tank, the buffer tank is arranged on an electronic scale, the electronic scale, the sub-packaging flowmeter and the command executing circuit are all connected with an input terminal of the control and processing circuit, the solenoid valve is connected with an output terminal of the control and processing circuit, a sub-packaging pump of a sub-packaging machine is a rotary-valve ceramic pump capable of carrying out secondary sub-packaging, and the control and processing circuit controls opening or closing of the rotary-valve ceramic pump according to the metered value of the sub-packaging flowmeter. The photoelectric switch arranged at a bottle-feeding and wheel-moving place of the sub-packaging machine can detect lack of bottles and prevent maloperation, so waste and pollution of eye drops are avoided.

Description

technical field [0001] The invention relates to the technical field of liquid medicine dispensing, in particular to an eye drop dispensing control system. Background technique [0002] The eye drops are subpackaged after liquid preparation and two-stage sterile filtration. Existing dispensing machine in the middle does not have the dispensing machine that is specially applied to dispensing eye drops, all is to carry out the dispensing of eye drops with common medicine liquid dispensing machine. Among the existing liquid medicine dispensing machines, such as the Chinese invention patent "An Intelligent Remotely Controlled Liquid Medicine Filling Electronic Control System" with the publication number CN103130170A, it includes a central control processing circuit connected to a power circuit, and a central control circuit connected to the central control The information acquisition circuit and the command execution circuit connected to the processing circuit, the information a...
