[0029] Embodiment
[0030] As Figure 1As shown, in this embodiment, a processing device for reducing the extractable content of medical membranes is provided, which comprises a solution storage tank 1, a constant temperature oscillation water bath 3 with a sealing cover, a membrane 4, a liquid tank 5, an RO membrane block 11, a pure water collection tank 12, and a high-concentration extract liquid collection container 13. The solution storage tank 1 is connected to the liquid inlet of the liquid tank 5 through a suction pump 2, and the liquid tank 5 is placed in the constant temperature oscillation water bath 3. After turning on the switch of the constant temperature oscillation water bath 3, the water bath is heated and oscillated. The liquid tank 5 is connected to the membrane 4 through a clamp 8. The membrane 4 is connected to a corresponding circulating pump 9. After turning on the circulating pump, the liquid in the liquid tank 5 circulates in and out of the membrane 4. The liquid tank 5 is provided with a liquid level meter 6 for monitoring the real-time liquid level. The liquid tank 5 is provided with an online refractometer detection device 7 for monitoring the real-time solution concentration. When the solution concentration is higher than the set value, the emptying pump 10 is automatically turned on. When the liquid level meter drops to the low position, the emptying pump 10 is automatically turned off and the suction pump 2 is turned on to add liquid to the liquid tank. The outlet of the emptying pump 10 is connected to the RO membrane block 11, which is used to concentrate the liquid discharged by the emptying pump 10. The concentrated extract liquid is collected into the high-concentration extract liquid collection container 13, and the permeate is collected into the pure water collection tank 12 as pure water for reuse.
[0031] The processing device for reducing the extractable content of medical membranes described in this embodiment can include the following process operation steps in specific applications:
[0032] Extract liquid circulation: The extract liquid is generally selected from 10%-30% ethanol, isopropyl alcohol or pure water, and the water-soluble and fat-soluble extractables are removed by the different solubilities of water and alcohol. The extract liquid is delivered to the liquid tank in the constant temperature oscillation water bath through the suction pump. The constant temperature oscillation water bath provides a stable and sealed temperature environment to ensure that the extract liquid maintains a constant temperature during the circulation process. In addition, the oscillation mode also accelerates the contact and circulation of the extract liquid and the product. The circulation time is generally 1-2h.
[0033] Membrane treatment: The medical membranes (such as membrane filaments, membrane sheets, membrane columns, membrane packages, filter cartridges, etc.) are fixed by different types of clamps and connected to the circulating pump. The circulating pump drives the extract liquid to circulate through the membrane inside the liquid tank, so as to extract and reduce the extractable content in the membrane.
[0034] Solution concentration monitoring: The liquid tank is provided with an online refractometer detection device, which can monitor the concentration of the solution in the liquid tank in real time.
[0035] Automatic control: The online refractometer detection is connected to the suction pump, circulating pump and emptying pump through wireless sensors. When the detected solution concentration exceeds the preset value, the system automatically stops the suction pump and circulating pump, and starts the emptying pump to empty the solution in the liquid tank.
[0036] Solution evacuation and replenishment: After the evacuation pump evacuates the solution in the liquid tank to a set low liquid level, the suction pump is restarted to replenish the extraction liquid to the liquid tank, and the circulation process is restarted.
[0037] Green cycle: The outlet of the evacuation pump is connected to the RO membrane module, and the RO membrane is used to concentrate the evacuated liquid. The concentrated extraction liquid is collected in the high-concentration extraction liquid collection container, and the permeate is collected in the pure water tank and can be reused as pure water.
[0038] Data recording and monitoring: Optional accessories include data lines, data recorders, wireless transmission modules, and mobile terminals, which can be used to record test data and allow users to remotely monitor the operating status of the processing device.
[0039] In summary, the processing device for reducing the extractable content of the pharmaceutical membrane according to the embodiments of the present application can significantly reduce the concentration of extractable substances in the subsequent use process by processing the pharmaceutical membrane. This helps to improve the safety and quality of pharmaceutical products and reduce the health risks of patients. When the sensor automatically monitors the concentration of the extraction liquid to the upper limit, the pump evacuation mode is started, avoiding secondary pollution of the membrane and the need for manual intervention, greatly improving the efficiency and automation level of the equipment. And the extracted extraction liquid is further concentrated by the RO membrane, and the pure water can be recycled. This method not only improves the utilization rate of water resources, but also reduces wastewater discharge, and has good economic and environmental benefits.
