[0033] Please refer to FIG1 . An embodiment of the present application provides a pharmaceutical water preparation device, including a liquid storage module 100, a heating module 210, a sterilization module 220, a first pipeline 300, a water production module 400, and a flushing and discharge module 500. The liquid storage module 100 has a liquid storage chamber 110, a liquid outlet 120, and a reflux port 130 that are connected to each other. The liquid storage chamber 110 is used to store liquid; the heating module 210 and the sterilization module 220 are both connected to the liquid storage chamber 110; the first pipeline 300, a water production module 400, and a flushing and discharge module 500. One end of the pipeline 300 is connected to the liquid outlet 120, and the other end of the first pipeline 300 is connected to the reflux port 130; the water production module 400 is arranged in the first pipeline 300 and is provided with a water production port 410, which is connected to the first pipeline 300 and is provided with a first flow control component 420; the flushing and discharge module 500 is arranged in the first pipeline 300 and is provided with a flushing and discharge port 510, which is connected to the first pipeline 300 and is provided with a second flow control component 520.

[0034] The above-mentioned pharmaceutical water preparation device, before formally producing pharmaceutical water, closes the first flow control component 420 and opens the second flow control component 520. At this time, the liquid sterilized by the sterilization module 220 flows out from the liquid outlet 120 and is discharged through the flushing and discharging module 500. The staff detects the liquid discharged from the flushing and discharging port 510. If the detection index is qualified, it indicates that the quality of the pharmaceutical water produced by the preparation device meets the standard. At this time, open the first flow control component 420 and close the second flow control component 520. The liquid sterilized by the sterilization module 220 flows out from the liquid outlet 120 and is discharged through the water production module 400, and then the pharmaceutical water that meets the quality standard is discharged at the water production port 410; if the detection index is unqualified, it indicates that the pharmaceutical water produced by the preparation device meets the standard. It is clear that the quality of the liquid produced by the preparation device does not meet the standard. At this time, the first flow control component 420 and the second flow control component 520 are closed, and the heating module 210 heats the liquid in the liquid storage chamber 110 to reach the sterilization temperature. The liquid reaching the sterilization temperature flows from the liquid outlet 120 to the first pipeline 300, and flows back to the liquid storage chamber 110 through the reflux port 130, thereby performing the next round of high-temperature sterilization. In this process, the liquid reaching the sterilization temperature can sterilize and disinfect the liquid storage mechanism, the first pipeline 300, the water production module 400 and the flushing and discharge module 500 during the flow; compared with traditional technologies, the above-mentioned pharmaceutical water preparation device can ensure that the quality of the pharmaceutical water produced meets the standards and improve the pharmaceutical qualification rate of the pharmaceutical system.

[0035] In one embodiment, the liquid storage module 100 includes a liquid storage tank, a liquid storage cavity 110 is defined inside the liquid storage tank, and the heating module 210 and the sterilization module 220 are both disposed in the liquid storage cavity 110 .

[0036] Furthermore, the heating module 210 includes a heat exchanger. The heat exchanger disposed in the liquid storage chamber 110 can directly contact the liquid to ensure heating efficiency.

[0037] In some embodiments, the sterilization module 220 can be sterilized by chemical means, such as adding chemical agents for sterilization into the liquid; in other embodiments, high temperature sterilization or ultraviolet sterilization can also be used, which will not be repeated here.

[0038] In some embodiments, the water production module 400 may be a pipeline provided with a water production port 410 . In other embodiments, the water production module 400 may also be a container provided with a water production port 410 for caching liquid, etc., which is not specifically limited here.

[0039] Furthermore, before the preparation device is put into production to prepare pharmaceutical water, the first flow control element 420 is closed and the second flow control element 520 is opened. At this time, the liquid flows out from the liquid outlet 120 and is discharged through the flushing and discharge module 500 to flush out impurities or foreign matter in the preparation device.

[0040] Please refer to Figure 1. In one embodiment, the water production module 400 includes a second pipeline 430, which is connected to the first pipeline 300 and has a water production port 410. The flushing and discharge module 500 also includes a third pipeline 530, which is connected to the first pipeline 300 and has a flushing and discharge port 510.

[0041] The liquid sterilized by the sterilization module 220 flows from the liquid outlet 120 to the first pipeline 300, and is discharged from the flushing discharge port 510 of the third pipeline 530 for testing related indicators. After the test is qualified, the first flow control member 420 is opened and the second flow control member 520 is closed, and the liquid in the first pipeline 300 flows to the second pipeline 430 and is discharged from the water production port 410 to obtain pharmaceutical water that meets the quality standards. Such a setting has low implementation cost and can ensure the reliability of liquid transportation.

[0042] In some embodiments, the water outlet 410 may be disposed at the end of the second pipeline 430 , ie, at the pipe mouth. In other embodiments, the water outlet 410 may also be disposed on the side wall of the second pipeline 430 , which is not specifically limited here.

[0043] In some embodiments, the flushing discharge port 510 may be disposed at the end of the third pipeline 530 , ie, at the pipe mouth. In other embodiments, the flushing discharge port 510 may also be disposed on the side wall of the third pipeline 530 , which is not specifically limited here.

[0044] Please refer to Figures 1 and 2. In one embodiment, the pharmaceutical water preparation device also includes a third flow control member 610 and a fourth flow control member 620. The third flow control member 610 and the fourth flow control member 620 are both arranged in the first pipeline 300. The third flow control member 610 is located in the upstream section of the fourth flow control member 620. One end of the second pipeline 430 is connected to the first pipeline 300 and is arranged on the side of the third flow control member 610 close to the liquid outlet 120. The other end of the second pipeline 430 is connected to the first pipeline 300 and is arranged between the third flow control member 610 and the fourth flow control member 620. The water production port 410 is opened between the two ends of the second pipeline 430. One end of the third pipeline 530 is connected to the first pipeline 300 and is arranged between the third flow control member 610 and the fourth flow control member 620. The other end of the third pipeline 530 is provided with a flushing discharge port 510.

[0045] Before the formal production of pharmaceutical water, the second flow control member 520 is opened, and the first flow control member 420, the third flow control member 610 and the fourth flow control member 620 are closed. At this time, the liquid sterilized by the sterilization module 220 flows out from the liquid outlet 120, and passes through the front section of the first pipeline 300, the second pipeline 430 and the third pipeline 530 respectively. The liquid finally flows out through the filling and washing discharge port, and the staff detects the liquid flowing out of the filling and washing discharge port; if the detection index is qualified, it indicates that the quality of the pharmaceutical water produced by the preparation device meets the standard. At this time, the first flow control member 420 and the third flow control member 610 are opened, and the second flow control member 520 and the fourth flow control member 620 are closed. The liquid sterilized by the sterilization module 220 flows out from the liquid outlet 120 and is divided into two flows on the first pipeline 300, one of which flows to the water production port 410 through one end of the second pipeline 430, and the other flows through the second The other end of the pipeline 430 flows to the water outlet 410 to realize dual-channel water supply at the water outlet 410, ensuring that there is no dead water section in the second pipeline 430 as a whole, preventing the growth of microorganisms in the second pipeline 430, and then producing pharmaceutical water with qualified quality at the water outlet 410; if the detection index is unqualified, it indicates that the quality of the liquid produced by the preparation device does not meet the standard. At this time, the fourth flow control element 620 is opened, the first flow control element 420, the second flow control element 520 and the third flow control element 610 are closed, and the heating module 210 heats the liquid in the liquid storage chamber 110 to reach the sterilization temperature. The liquid reaching the sterilization temperature flows out from the liquid outlet 120, and passes through the front section of the first pipeline 300, the second pipeline 430 and the rear section of the first pipeline 300 in turn for sterilization, and finally flows back to the liquid storage chamber 110 through the reflux port 130, so as to carry out the next round of high-temperature sterilization, ensuring that each pipeline in the preparation device is effectively sterilized.

[0046] As a further explanation, when it is necessary to flush the interior of the preparation device or to test the produced pharmaceutical water, the second flow control element 520 is opened, and the first flow control element 420, the third flow control element 610 and the fourth flow control element 620 are closed. At this time, the liquid can pass through the front section of the first pipeline 300, the second pipeline 430 and the third pipeline 530 in sequence, thereby cleaning the main pipelines in the preparation device to ensure the cleaning effect and detection accuracy.

[0047] On this basis, in order to ensure that there is no dead water section inside the preparation device, when the staff opens the first flow control component 420 and the third flow control component 610, and closes the second flow control component 520 and the fourth flow control component 620, the liquid in the first pipeline 300 is divided into two flows, one of which flows to the water production port 410 through one end of the second pipeline 430, and the other flows to the water production port 410 through the other end of the second pipeline 430, so as to realize dual-path water supply at the water production port 410 and prevent bacteria from growing in the second pipeline 430.

[0048] Furthermore, when it is necessary to disinfect the interior of the preparation device, the fourth flow control element 620 is opened, and the first flow control element 420, the second flow control element 520 and the third flow control element 610 are closed. The liquid reaching the sterilization temperature passes through the front section of the first pipeline 300, the second pipeline 430 and the rear section of the first pipeline 300 in sequence, and finally flows back into the liquid storage chamber 110 through the reflux port 130, so as to carry out the next round of high-temperature sterilization. In this way, the liquid reaching the sterilization temperature can flow through the main pipeline in the preparation device to achieve pasteurization and ensure the sterilization effect.

[0049] Please refer to Figure 1. In one embodiment, the sterilization module 220 includes an ultraviolet irradiation element, which is used to irradiate ultraviolet rays to the liquid to convert organic matter in the liquid into charged particles. The pharmaceutical water preparation device also includes an electric deionization module 710. The electric deionization module 710 is connected to the first pipeline 300 and is arranged between the liquid outlet 120 and the third flow control element 610. The electric deionization module 710 is used to remove charged particles.

[0050] The ultraviolet irradiation element irradiates ultraviolet rays to the liquid to convert organic matter in the liquid into charged particles. The electric deionization module 710 on the first pipeline 300 then adsorbs and removes the charged particles, thereby reducing the organic matter content in the liquid to remove the living nutritional environment of microorganisms and prevent the growth of microorganisms.

[0051] Furthermore, the ultraviolet irradiation component includes an ultraviolet lamp arranged in the liquid storage chamber 110. The ultraviolet lamp can not only sterilize and disinfect the liquid, but also the inner wall of the liquid storage chamber 110, the heat exchanger and various valve bodies connected to the liquid storage tank are all within the irradiation range of the ultraviolet lamp, thereby effectively controlling the growth of microorganisms.

[0052] Please refer to FIG. 1 . In one embodiment, the pharmaceutical water preparation device further includes a filter module 720 . The filter module 720 is connected to the first pipeline 300 and is disposed between the liquid outlet 120 and the third flow control member 610 .

[0053] The filtration module 720 can filter impurities such as macromolecules and colloids in the liquid to ensure that the impurity content of the produced pharmaceutical water is lower than the relevant regulations, thereby improving the quality of the produced pharmaceutical water.

[0054] In one embodiment, the filtration module 720 is an ultrafiltration device, which has low implementation cost and reliable filtering effect on impurities.

[0055] Please refer to FIG. 1 . In one embodiment, the pharmaceutical water preparation device further includes a delivery pump 730 . The delivery pump 730 is connected to the first pipeline 300 and is used to provide power for the flow of the liquid.

[0056] The delivery pump 730 enables the liquid to flow in the preparation device to ensure the normal production of pharmaceutical water.

[0057] Please refer to Figures 1 and 2. In one embodiment, when there is no water demand at the rear end of the water production port 410, the fourth flow control element 620 is opened, the first flow control element 420, the second flow control element 520 and the third flow control element 610 are closed, and the delivery pump 730 is operated at low power to keep the preparation device as a whole in a low-pressure operating state. In this way, not only can the water demand at the rear end of the water production port 410 be responded to quickly, but the risk of microbial growth can also be reduced.

[0058] Please refer to FIG. 1 . In one embodiment, the pharmaceutical water preparation device further includes a fifth flow control member 630 . The liquid storage module 100 further includes a liquid discharge port 140 connected to the liquid storage chamber 110 . The fifth flow control member 630 is disposed at the liquid discharge port 140 .

[0059] The fifth flow control member 630 disposed at the liquid discharge port 140 can control the opening and closing of the liquid discharge port 140. When the liquid in the liquid storage chamber 110 needs to be completely drained, the fifth flow control member 630 is opened to allow the liquid in the liquid storage chamber 110 to be discharged through the liquid discharge port 140. The control process is convenient.

[0060] For example, when the staff needs to perform large-scale cleaning and maintenance on the preparation equipment, the liquid remaining in the liquid storage chamber 110 needs to be discharged through the drain port 140 .

[0061] Please refer to Figure 1. In one embodiment, the pharmaceutical water preparation device also includes a sixth flow control component 640. The liquid storage module 100 is also provided with a liquid inlet 150 connected to the liquid storage chamber 110. The liquid inlet 150 is used to communicate with the liquid supply module (not shown in the figure). The sixth flow control component 640 is arranged at the liquid inlet 150.

[0062] The liquid supply module can transport and replenish liquid into the liquid storage chamber 110 through the liquid inlet 150. When the liquid in the liquid storage chamber 110 is exhausted, the sixth flow control component 640 is opened to allow the liquid supply module to replenish liquid into the liquid storage chamber 110 through the liquid inlet 150, thereby ensuring that the production of pharmaceutical water can continue.

[0063] Referring to FIG. 1 , in one embodiment, the sixth flow control element 640 includes a liquid inlet valve 641 and a liquid level monitoring portion 642. The liquid inlet valve 641 is disposed at the liquid inlet port 150. The liquid level monitoring portion 642 is connected to the liquid inlet valve 641 and is located in the liquid storage chamber 110. The liquid level monitoring portion 642 is used to monitor the liquid level of the liquid in the liquid storage chamber 110.

[0064] When the liquid level monitoring unit 642 detects that the liquid level in the liquid storage chamber 110 is lower than the preset liquid level, the liquid inlet valve 641 opens; when the liquid level monitoring unit 642 detects that the liquid level in the liquid storage chamber 110 is greater than or equal to the preset liquid level, the liquid inlet valve 641 closes.

[0065] The liquid level detection unit can detect the liquid level of the liquid in the liquid storage chamber 110. When the liquid level is lower than the preset level, it indicates that the liquid in the liquid storage chamber 110 is exhausted. At this time, the liquid inlet valve 641 is opened, and the liquid supply module replenishes the liquid into the liquid storage chamber 110 through the liquid inlet 150. When the liquid level in the liquid storage chamber 110 is greater than or equal to the preset level, the liquid inlet valve 641 is closed. With such a configuration, the pharmaceutical water preparation device can automatically replenish the liquid into the liquid storage chamber 110 to ensure that the production of pharmaceutical water can continue.

[0066] Furthermore, the liquid level monitoring part 642 is a float, and the liquid inlet valve 641 is a mechanical liquid level control valve. When the liquid level in the liquid storage chamber 110 is lower than the preset liquid level, the height of the float decreases. At this time, the mechanical liquid level control valve automatically opens to replenish the liquid in the liquid storage chamber 110.

[0067] In one embodiment, the first flow control element 420 , the second flow control element 520 , the third flow control element 610 , the fourth flow control element 620 , the fifth flow control element 630 , and the sixth flow control element 640 are all valves.

[0068] Further, please refer to Figure 2, in which the second flow control component 520, the third flow control component 610 and the fourth flow control component 620 are combined with their corresponding pipelines to form a multi-channel integrated valve group 800. The multi-channel integrated valve group 800 can greatly shorten the length of the pipeline between valves and reduce the risk of microbial growth.

[0069] Please refer to FIG. 2 . In one embodiment, the multi-channel integrated valve group 800 is provided with a probe interface, which is located at the upstream section of the sixth flow control member 640 and is used to install a conductivity detection probe 810 to facilitate the detection of the conductivity of the liquid.

[0070] Please refer to FIG. 2 . In one embodiment, the multi-channel integrated valve group 800 is further provided with a sampling port 820 . The sampling port 820 is provided with a sampling valve to facilitate the staff to sample the liquid inside the valve group.

[0071] Please refer to FIG. 2 . In one embodiment, the multi-channel integrated valve assembly 800 is further provided with a respirator interface 830 . The respirator interface 830 is used to connect an external respirator to ensure the overall air pressure balance of the device.

[0072] Furthermore, a respirator valve is provided at the respirator interface 830 for opening or closing the respirator interface 830 .

[0073] Another embodiment of the present application provides a pharmaceutical system, including a pharmaceutical water preparation device as described in any of the above embodiments.

[0074] The above-mentioned pharmaceutical water preparation device, before formally producing pharmaceutical water, closes the first flow control component 420 and opens the second flow control component 520. At this time, the liquid sterilized by the sterilization module 220 flows out from the liquid outlet 120 and is discharged through the flushing and discharging module 500. The staff detects the liquid discharged from the flushing and discharging port 510. If the detection index is qualified, it indicates that the quality of the pharmaceutical water produced by the preparation device meets the standard. At this time, open the first flow control component 420 and close the second flow control component 520. The liquid sterilized by the sterilization module 220 flows out from the liquid outlet 120 and is discharged through the water production module 400, and then the pharmaceutical water that meets the quality standard is discharged at the water production port 410; if the detection index is unqualified, it indicates that the pharmaceutical water produced by the preparation device meets the standard. It is clear that the quality of the liquid produced by the preparation device does not meet the standard. At this time, the first flow control component 420 and the second flow control component 520 are closed, and the heating module 210 heats the liquid in the liquid storage chamber 110 to reach the sterilization temperature. The liquid reaching the sterilization temperature flows from the liquid outlet 120 to the first pipeline 300, and flows back to the liquid storage chamber 110 through the reflux port 130, thereby performing the next round of high-temperature sterilization. In this process, the liquid reaching the sterilization temperature can sterilize and disinfect the liquid storage mechanism, the first pipeline 300, the water production module 400 and the flushing and discharge module 500 during the flow; compared with traditional technologies, the above-mentioned pharmaceutical water preparation device can ensure that the quality of the pharmaceutical water produced meets the standards and improve the pharmaceutical qualification rate of the pharmaceutical system.
