Problems solved by technology

[0003] However, in the existing automatic dispensing device, when the syringe is used to inject liquid into the vial to dissolve the medicine, the pressure in the vial will increase due to the injection, so that there will be liquid medicine when the needle of the syringe is pulled out. squirting problem
The sprayed liquid medicine is easy to contaminate the automatic dispensing device, and it will also affect the subsequent process of quantitative suction of the liquid medicine

Embodiment 1

[0084] The invention provides a method for controlling liquid injection in vials, comprising the steps of:

[0085] (1) control and identify the information of the cillin bottle to be injected, and extract the preset injection volume information according to the information of the cillin bottle to be injected and generate a syringe needle entry instruction;

[0086] Specifically, the control to identify the vial information to be injected includes identifying vial station information and status information of the vial. In this embodiment 1, the vial is placed upside down, so that the preset vial for this station can be extracted. It can determine the appropriate position of the syringe needle when it enters the vial, for example, so that the syringe needle can be inserted to a certain distance from the bottom of the bottle, and the syringe needle entry command can be generated accordingly.

[0087] (2) According to the syringe needle entry instruction, control the syringe needle...

Embodiment 2

[0098] On the basis of embodiment 1, in further embodiment 2, the vial injection control method of the present invention is "according to the generated first syringe piston action command, control the piston of the syringe to perform the first action, and the syringe in the syringe After the solvent is injected in the vial" step, further include:

[0099] The control judges whether the position of the needle tip liquid inlet of the syringe needle is higher than the position of the liquid level in the vial, and according to the judgment result, determines whether to adjust the position of the syringe needle, and adjusts accordingly.

[0100] More specifically, the step of "controlling and judging whether the position of the needle tip liquid inlet of the syringe needle is higher than the liquid level in the vial, and determining whether to adjust the position of the syringe needle according to the judgment result, and adjusting accordingly" step further Including the following ...

Embodiment 3

[0107] The invention provides a method for controlling liquid injection in vials, comprising the steps of:

[0108] (1) control and identify the information of the cillin bottle to be injected, and extract the preset injection volume information according to the information of the cillin bottle to be injected and generate a syringe needle entry instruction;

[0109] Specifically, controlling the identification of the vial information to be injected includes identifying the vial station information and status information of the vial. In this embodiment 1, the vial is placed upright, so that the preset vial for this station can be extracted. The injection volume information of the bottle, and can determine the appropriate position when the syringe needle enters the vial, for example, the needle of the syringe can be inserted to the position that just passes through the rubber stopper of the vial (the liquid inlet of the syringe needle passes through the vial) rubber stopper) fro...

Abstract

The invention discloses a penicillin bottle liquid injection control method and a penicillin bottle liquid injection control device. The method comprises the steps that after the liquid is injected into a penicillin bottle , a part of air is pumped back, the positive pressure generated by liquid injection in the penicillin bottle can be removed, accordingly, the problem of liquid spaying when an injector pinhead is pulled out is solved, and the situation that the liquid is injected into the penicillin bottle by adopting an injector in an automatic dispensing medicine system is achieved; according to the method, two modes can be adopted, wherein one mode is that the injector is matched with the movement while the penicillin bottle is stationary, and the other mode is that the injector remains stationary while the penicillin bottle is matched with the movement.

Description

technical field [0001] The invention relates to the field of medical technology. More specifically, the present invention relates to a liquid injection control method for a vial and a liquid injection control device for a vial. Background technique [0002] At present, the method of preparing medicines in hospitals is mainly manual processing by medical staff, and nurses manually configure the liquid medicines according to the prescriptions issued by doctors. This method of manually preparing liquid medicine consumes a lot of time and energy for the nursing staff, and at the same time, the nursing staff is exposed to various medicines and solvents for a long time, which greatly increases the work risk of the nursing staff. Therefore, there have been some devices that can partially replace the work of medical staff and carry out automatic dispensing. [0003] However, in the existing automatic dispensing device, when the syringe is used to inject liquid into the vial to dis...
