Description

Liquid medicine transfer device of liquid preparation system

Technical Field

The utility model discloses a liquid medicine transfer device of a liquid preparation system, relates to the technical field of medicine production equipment, and particularly relates to a liquid transfer device in a liquid preparation system.

Background

With the development of medical technology, the pharmaceutical level is continuously improved, and the manufacturing technology of production equipment used by oral liquid products is more and more mature.

In the process of preparing the medicine, the medicine liquid in the liquid preparation tank is generally transferred to a storage tank for storage. The liquid medicine is introduced into the storage tank mainly through a liquid medicine pump such as a centrifugal pump and a pipeline connecting the liquid preparation tank and the storage tank.

However, in the prior art, in the process of pumping the liquid medicine in the liquid preparation tank by using a liquid medicine pump such as a centrifugal pump, the centrifugal pump needs to be closed immediately after most of the liquid medicine is pumped from the liquid preparation tank to the storage tank so as to prevent the centrifugal pump from idling and causing faults. Therefore, residual liquid medicine still can be remained in the pipeline, and after the pump is closed, the liquid medicine can flow back to the liquid preparation tank, so that a large amount of medicine waste can be caused. In addition, the residual liquid medicine in the pipeline is easy to cause secondary pollution.

In view of the above problems in the prior art, it is necessary to develop a novel liquid medicine transfer device for a liquid preparation system to overcome the problems in the prior art.

Disclosure of Invention

According to the problems that residual liquid medicine in a pipeline of the existing liquid medicine transfer device flows back and residual liquid medicine left in the pipeline easily causes secondary pollution, the residual liquid medicine transfer device mainly utilizes the fact that a residual liquid discharge system is arranged in the transfer device and matched with the improved liquid medicine transfer system, the residual liquid medicine after the liquid medicine is transferred is reduced, and the residual liquid medicine is discharged in time, so that the problem that the liquid medicine in the pipeline causes secondary pollution is avoided.

The technical means adopted by the utility model are as follows:

a drug solution transfer device of a fluid dispensing system, comprising: connecting a pipeline, a liquid preparation tank and a storage tank;

further, one end of the connecting pipeline is connected with the liquid preparation tank, and the other end of the connecting pipeline is respectively connected with the liquid medicine transfer system and the residual liquid discharge system;

further, the tail end of the liquid medicine transferring system is connected with the storage tank;

further, the raffinate discharge system discharges the raffinate in the system to an external treatment system.

Further, the medical fluid transfer system includes: a pneumatic diaphragm valve A, a rotor pump and a check valve;

further, the pneumatic diaphragm valve A, the rotor pump and the check valve are connected in sequence through a connecting pipeline;

further, the input end of the pneumatic diaphragm valve A is connected with the liquid preparation tank through a connecting pipeline;

further, the output end of the check valve is connected with the storage tank through a pipeline;

further, the liquid medicine transfer system functions to transfer the liquid medicine from the liquid preparation tank to the storage tank.

Further, the raffinate discharge system comprises: a pneumatic diaphragm valve B, a pipeline sight glass and an air blocker;

further, the pneumatic diaphragm valve B, the pipeline sight glass and the air blocker are sequentially connected through a connecting pipeline;

further, the input end of the pneumatic diaphragm valve B is connected with the liquid preparation tank through a connecting pipeline;

further, the output end of the air blocker is connected with an external processing system;

further, the residual liquid discharge system plays a role in timely discharging the residual liquid in the pipeline after the liquid medicine is transferred and preventing pollution.

Compared with the prior art, the utility model has the following advantages:

1. according to the liquid medicine transfer device of the liquid preparation system, the used rotor pump can still normally work when the amount of liquid medicine in the pipeline is small, so that the liquid medicine is transferred into the storage tank as much as possible, and the loss amount of the liquid medicine is reduced;

2. the liquid medicine transfer device of the liquid preparation system is provided with an automatic liquid discharge pipeline, residual liquid medicine is timely discharged under the control of a pneumatic diaphragm valve, and the pollution to the system caused by the back flushing of a floor drain is effectively prevented through an air blocker;

3. according to the liquid medicine transfer device of the liquid preparation system, the pipeline sight glass is arranged in the residual liquid discharge system, so that the condition in the discharge system can be observed visually, and operation reference is provided.
