Background

With the development of science and technology, traditional Chinese medicine is also continuously advancing to better meet the requirements of modern people, for example, traditional decoction is made into solid medicament. When the solid medicament is prepared, decocted liquid medicine needs to be transferred to solid preparation equipment, a decocting container is far away from the solid preparation equipment, and the liquid medicine is usually transferred through a pipeline at present. The existing liquid medicine transfer mode is more suitable for large pharmaceutical factories and is not suitable for pharmacies or hospitals.

Because the amount of the liquid medicine in each batch in a large pharmaceutical factory is sufficient, the residual amount of the liquid medicine in the pipeline can be controlled within the allowable range of the weight loss of the production batch. However, in the pharmacy mode of pharmacy or clinical prescription in hospital, generally, the medicament is prepared for one person at a time, the amount of the liquid medicine is limited, and when the system is adapted to automatic pharmaceutical equipment, the liquid medicine loss and residue in a transmission system have a large influence on the total amount of the medicament, even the curative effect of the medicament is influenced.

Examples

The distance of decoction decocte container and solid preparation equipment is far away, and in the transportation process, the liquid medicine remains and is main liquid medicine loss factor in the c transmission pipeline, and the embodiment of the application provides a decoction transmission equipment, and this decoction transmission equipment sets up between decoction decocte container and solid preparation equipment for transfer the liquid medicine that decocts well in the decoction decocte container to solid preparation equipment, be used for reducing transmission loss.

As shown in fig. 1, the decoction delivery apparatus includes a first buffer container 100 and a pressurizing means 500. The first buffer container 100 is connected with the decoction decocting container A through a first pipeline and is connected with the solid preparation device B through a second pipeline. The first and second pipes are not directly labeled in fig. 1, but those skilled in the art will understand how to realize the sequential connection of three containers by two pipes, and as shown in fig. 1, the first pipe includes a first pipe segment 210 and a second pipe segment 220, and the second pipe includes a third pipe segment 310 and a fourth pipe segment 320.

The liquid medicine in the decoction decocting container A is filtered, enters the first cache container 100 from the first pipeline, and is conveyed to the solid preparation device B through the second pipeline.

The inner diameter of the first pipeline is larger than that of the second pipeline, and the input amount of the first cache container 100 is large and the output amount of the first cache container is small, so that certain liquid medicine can be accumulated in the first cache container 100, and the second pipeline is guaranteed to be full of the liquid medicine.

The first pipeline is provided with a first valve 221, and after the liquid medicine in the decoction decocting container A completely enters the first buffer container 100, the first valve 221 is closed.

The pressurizing device 500 is connected to the first buffer container 100, the pressurizing device 500 may be any device that provides clean gas, such as an air compressor, an air pump, a compressed air bottle, etc., and the pressurizing device 500 introduces gas into the first buffer container 100 after the first valve 221 is closed, so that the liquid medicine in the first buffer container 100 and the second pipeline is delivered to the solid preparation device B by using the gas.

Alternatively, the outlet of the gas pipe 510 of the pressurization device 500 and the outlet of the first pipe are disposed at the top of the first buffer container 100, and the inlet of the second pipe is disposed at the bottom of the first buffer container 100. The gas is directly introduced above the liquid level and pushes the liquid medicine downwards, so that the gas is prevented from entering the liquid medicine, and bubbles are prevented from entering the second pipeline to influence the continuous conveying of the liquid medicine.

Because the liquid medicine in first buffer container 100 and the second pipeline can all input solid preparation equipment B under the atmospheric pressure effect, and gaseous inner wall that can also sweep first buffer container 100 and sweep the second pipeline, the liquid medicine is difficult to remain in first buffer container 100 or in the second pipeline, make the liquid medicine residue amount of this application technical scheme be less than current transmission technology's residue greatly, play the effect that reduces the liquid medicine residue amount in the transmission process, alleviate the problem that the liquid medicine loss influences the curative effect of medicine.

Optionally, the first buffer container 100 is disposed near the decoction decocting container a, so that the length of the first pipeline is relatively short and the residual liquid medicine in the first pipeline is less, thereby further reducing the residual liquid medicine loss during the transmission process.

In order to further reduce the residual amount of the liquid medicine, the inner walls of the first pipeline, the second pipeline and the first buffer container 100 are provided with hydrophobic coatings. Such as a fluorine-containing coating, a silicon-containing coating, or a smooth metal layer. In this embodiment, the inner walls of the first pipeline, the second pipeline and the first buffer container 100 are all provided with teflon coatings. Through setting up hydrophobic coating, the adsorption affinity between liquid medicine and the inner wall is little, and the liquid medicine is difficult to stick the wall, even there is a small amount of liquid medicine to stick the wall, under gaseous sweeping, the liquid medicine also is blown away easily and is exported.

When the inner diameter of the second pipeline is too small, the conveying speed is too slow, and when the inner diameter of the second pipeline is too large, a part of the second pipeline is occupied by liquid medicine on the same cross section of the pipeline, and the other part of the second pipeline allows gas to flow, so that the liquid medicine cannot be completely output by the gas. Optionally, the internal diameter of second pipeline sets up to 4 ~ 20mm, guarantees that the liquid medicine can be carried very fast to avoid the liquid medicine to amass in the second pipeline, thereby realize reducing the remaining effect of liquid medicine under very fast conveying speed.

In order to facilitate accurate control of the liquid drug delivery process, the liquid drug delivery device is further provided with a first detection means 110 and a controller. The first detecting means 110 is used for detecting the storage amount in the first cache container 100. The controller is electrically connected to the first detecting device 110, the first valve 221 and the pressurizing device 500.

The first detecting means 110 may be a liquid level meter, and the amount of the liquid stored in the first buffer container 100 is obtained by detecting the liquid level in the first buffer container 100.

Before use, the amount of the liquid medicine in the first cache container 100 when the liquid medicine in the decoction decocting container A just completely enters the first cache container 100 is calculated according to the total amount of the liquid medicine in the decoction decocting container A, the flow rate of the first pipeline and the flow rate of the second pipeline, and the amount of the liquid medicine stored in the first cache container 100 at the moment is selected as a preset value.

When the storage capacity of the first buffer container 100 reaches a preset value, it indicates that all the liquid medicine in the decoction decocting container a has entered the first buffer container 100, and the first detecting device 110 sends a first signal at this time.

After receiving the first signal, the controller controls the first valve 221 to close to make the first buffer container 100 airtight, and controls the pressurizing device 500 to open to make only the first buffer container 100 output from the second pipeline.

Optionally, a second valve 311 is disposed in the second pipe, and the second valve 311 is electrically connected to the controller. When the first detecting device 110 sends the first signal, the controller simultaneously controls the second valve 311 to open.

That is, when the first valve 221 is opened, the second valve 311 is closed, the first buffer container 100 can only be filled, and the first detecting device 110 is triggered to send the first signal with a preset value equal to the total amount of the decoction in the decoction decocting container a. The second pipeline is blocked by the second valve 311, so that the variable is reduced, whether the liquid medicine in the decoction decocting container A completely enters the first buffer container 100 can be determined more accurately, and the control precision is improved.

When the first detecting device 110 detects that the amount of the liquid medicine in the first buffer container 100 is zero, the first detecting device 110 sends a second signal, and the controller controls the pressurizing device 500 to be closed after a predetermined time according to the second signal.

When the amount of the liquid medicine in the first buffer container 100 is zero, the liquid medicine in the second pipeline may not be completely output, and the pressurizing device 500 is closed after a predetermined time to continuously input gas into the first buffer container 100, so that the gas enters the second pipeline from the first buffer container 100, and the whole liquid medicine in the second pipeline is ensured to be output.

Optionally, a second detecting device 321 is disposed at the end of the second pipeline, and the second detecting device 321 is configured to detect the flow rate in the second pipeline and send a third signal when the flow rate in the second pipeline is zero. The second sensing device 321 may optionally be a flow meter.

The second detecting device 321 is electrically connected to the controller, and the controller controls the pressurizing device 500 to be turned off after receiving the second signal and the third signal. Thereby further avoiding pressurization device 500 to close in advance, guaranteeing that the liquid medicine is all output, still making gas continuously sweep the inner wall of first buffer container 100 and the inner wall of second pipeline, further reducing the liquid medicine and remaining.

Optionally, a positive displacement pump 700 is further disposed on the second pipeline, and the positive displacement pump 700 is configured to pump the liquid medicine in the second pipeline to compensate for power loss during the liquid medicine transmission process, so as to ensure that the liquid medicine in the second pipeline is delivered to the solid preparation apparatus B.

Through caching and long-distance transportation, the concentration of liquid medicine entering the solid preparation equipment B may be different, and the liquid medicine concentration at the early stage is high, the liquid medicine concentration at the later stage is low, or the liquid medicine concentration at the early stage is low and the liquid medicine concentration at the later stage is high. The difference of the liquid medicine concentration may cause the particle forming quality of the solid medicament manufactured by the solid preparation device B to be greatly different, and the curative effect of the medicament is influenced. In order to ensure the quality of the solid medicament molding, a stirring device 600 is further arranged between the first buffer container 100 and the solid preparation device B.

The agitation apparatus 600 includes a second buffer container 610 and an agitator 620, and the agitator 620 is disposed in the second buffer container 610.

The aforementioned second detecting device 321 is installed at the end of the fourth pipe section 320.

The liquid medicine in the first buffer container 100 enters the second buffer container 610, is stirred by the stirrer 620 and then enters the solid preparation device B.

The stirrer 620 includes an impeller and a motor, the motor is installed in the second buffer container 610, and an output shaft of the motor is connected to a rotating shaft of the impeller, so that the motor drives the impeller to rotate when operating, thereby stirring the liquid medicine to be uniformly mixed.

When dregs of a decoction are left in the liquid medicine, the second pipeline with smaller inner diameter is easy to block, the transmission efficiency is influenced, and the work of the solid preparation equipment B is hindered. Optionally, the decoction delivery apparatus further includes a filtering device 400, and the filtering device 400 filters the liquid medicine output from the decoction decocting container a so as to purify the liquid medicine entering the first buffer container 100.

The backwashing mechanism 430 includes a first flushing pipe 431 and a first slag discharging pipe 432, the first flushing pipe 431 connecting the flushing device and the space of the first filtering container 411 not surrounded by the first filtering member 412, and the first slag discharging pipe 432 connecting the space of the first filtering container 411 surrounded by the first filtering member 412 and the outer space.

Wherein, the first liquid inlet pipe 413, the first liquid outlet pipe 414, the first flushing pipe 431 and the first slag discharge pipe 432 are respectively provided with a valve for controlling the on-off. When the first filtering mechanism 410 works, the first liquid inlet pipe 413 and the first liquid outlet pipe 414 are unblocked, and the first flushing pipe 431 and the first slag discharge pipe 432 are blocked, so that the function of filtering liquid medicine is achieved; when the second filtering mechanism 420 is not operated, the first liquid inlet pipe 413 and the first liquid outlet pipe 414 are blocked, so that the first filtering mechanism 410 is disconnected from the first pipeline, at this time, the first flushing pipe 431 and the first residue discharge pipe 432 are unblocked, and residue intercepted in the first filtering member 412 can be flushed out from the first residue discharge pipe 432 through the flushing device.

Similarly, referring to fig. 2 again, the second filtering mechanism 420 includes a second filtering container 421 and a second filtering member 422, the second filtering member 422 divides the inner space of the second filtering container 421 into two parts, one part is located in the enclosure of the second filtering member 422, and the other part is located outside the second filtering member 422.
