However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0031] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0032] Throughout the specification, when an element (such as a layer, region or substrate) is referred to as being "on" another element, "connected to" another element, "coupled to" another element, "adjacent to" another element, "on top of" another element, or "covering" another element, it can be directly on, connected to, coupled to, adjacent to, on top of, or covering the other element, or one or more other elements can be interposed therebetween. In contrast, when an element is referred to as being "directly on", "directly connected to", "directly coupled to", "directly adjacent to", "directly on top of", or "directly covering" another element, there are no other elements interposed therebetween.

[0033] As used herein, the term "and / or" includes any one of the listed items and any combination of two or more of the listed items.

[0034] Although terms such as "first", "second", and "third" can be used herein to describe various components, assemblies, regions, layers or sections, these components, assemblies, regions, layers or sections are not limited by these terms. Rather, these terms are only used to distinguish one component, assembly, region, layer or section from another component, assembly, region, layer or section. Thus, a component, assembly, region, layer or section referred to as a first component, assembly, region, layer or section in one example described herein can also be referred to as a second component, assembly, region, layer or section in another example without departing from the teachings of the examples.

[0035] For ease of description, spatial relationship terms, such as "on", "upper", "beneath", and "lower", can be used herein to describe one element's relationship to another element as illustrated in the figures.

Furthermore, although examples described herein have a variety of configurations, other configurations are possible in which are apparent after understanding the disclosure provided herein.

[0039] Before the present application, the integrity detection of the filter cartridge needs to be performed offline, i.e., the filter cartridge needs to be disassembled and then the integrity of the filter cartridge is detected. However, for a system with high cleanliness requirement, the detection process will bring external microbial factors, which cannot guarantee the cleanliness and is complicated to operate. In addition, the detection process data cannot be recorded and transmitted.

[0040] In view of this, the present application provides a filter cartridge integrity detection system, thereby solving the problem that the integrity detection of the filter cartridge needs to be performed offline.

[0041] Reference is made below to Figures 1 to 4 a filter cartridge integrity detection system according to some embodiments of the present application.

[0042] As Figure 1As shown, the filter integrity testing system of this application includes a respirator 200, a purified water source 300, a compressed air source 400, a drain section 600, a first pipeline 10, a second pipeline 20, and an integrity tester 500. The respirator 200 includes an internal filter element. A first port and a second port are located at the bottom of the respirator 200, and a third port is located at the top. The compressed air source 400 is connected to the integrity tester 500. The purified water source 300 and the integrity tester 500 are connected to the first port of the respirator 200 via the first pipeline 10 and the second pipeline 20, respectively. Both the second and third ports of the respirator 200 are connected to the drain section 600. Purified water from the purified water source 300 can enter the respirator 200 through the first port via the first pipeline 10 and exit through the third port. Gas from the compressed air source 400 can sequentially pass through the integrity tester 500 and the second pipeline 20 and enter the respirator 200 through the first port.

[0043] When performing an integrity test on the filter element:

[0044] First, such as Figure 2 As shown, when the purified water source 300 is turned on, the purified water from the purified water source 300 can be forced into the respirator 200 through the first port of the respirator 200 via the first pipe 10, and then discharged from the third port to the drain section 600 to wet the filter element.

[0045] Then, as Figure 3 As shown, open the second port at the bottom of the respirator 200 to drain excess liquid after the filter is wetted.

[0046] Finally, as Figure 4 As shown, when the compressed air source 400 and the integrity tester 500 are turned on, the compressed gas from the compressed air source 400 can pass through the integrity tester 500 and the second pipeline 20 in sequence and enter the respirator 200 through the first port. At this time, the integrity tester 500 can perform online integrity testing on the filter element.

[0047] As described above, the filter element integrity testing system of this application can perform online integrity testing on filter elements. The testing process is simple, the system is closed and free from external interference, ensuring system cleanliness, and it is highly applicable and practical. Furthermore, it can also perform data transmission and recording. The filter element integrity testing system of this application is applicable to various filter element integrity testing systems, especially those in the pharmaceutical industry.

[0048] In the embodiments of this application, in order to further improve the safety, operability, and accuracy of the filter integrity testing system, such as... Figure 1As shown, the filter integrity testing system of this application further includes a third pipeline 30, a first valve 110, and a second valve 120. The purified water source 300 and the integrity tester 500 are connected to the first end of the third pipeline 30 via the first pipeline 10 and the second pipeline 20, respectively. The second end of the third pipeline 30 is connected to the first port of the respirator 200. The first valve 110 is located in the first pipeline 10, and the second valve 120 is located in the second pipeline 20.

[0049] When performing an integrity test on the filter element:

[0050] First, such as Figure 2 As shown, when the purified water source 300 and the first valve 110 are turned on and the second valve 120 is turned off, the purified water from the purified water source 300 can pass through the first pipe 10 and the third pipe 30 in sequence and be forced into the respirator 200 through the first port of the respirator 200, and then be discharged from the third port to the drain section 600 to wet the filter element.

[0051] Then, as Figure 3 As shown, the second port of the respirator 200 is opened to drain excess liquid after the filter is wetted.

[0052] Finally, as Figure 4 As shown, the second valve 120, compressed air source 400 and integrity tester 500 are opened, and the first valve 110 is closed. Compressed gas from the compressed air source 400 can pass through the integrity tester 500, the second pipeline 20 and the third pipeline 30 in sequence and enter the respirator 200 through the first port. At this time, the integrity tester 500 can perform online integrity testing on the filter element.

[0053] In the embodiments of this application, in order to further improve the safety, operability, and integration between various pipelines of the filter element integrity detection system, such as... Figure 1 As shown, the filter element integrity testing system of this application also includes a fourth pipe 40, a four-way connector 900, and a third valve 130. The four-way connector 900 is connected to the second end of the first pipe 10, the second end of the second pipe 20, the first end of the third pipe 30, and the first end of the fourth pipe 40, respectively. The second end of the fourth pipe 40 is connected to the drain section 600, and the third valve 130 is located on the fourth pipe 40. Figure 1 The four ports of the four-way connector 900 can be connected to the first pipe 10, the second pipe 20, the third pipe 30 and the fourth pipe 40 via a chuck.

[0054] With this setup, when the filter element is wetted and excess liquid is being discharged, the third valve 130 can be opened to accelerate the discharge of excess liquid. In other words, if... Figure 3As shown, when discharging excess liquid, it can be discharged through the second port of the respirator 200; on the other hand, it can also be discharged through the first port of the respirator 200, i.e., from the first port of the respirator 200 - third pipe 30 - fourth pipe 40 (third valve 130 is open) - drain section 600. This increases the discharge rate of excess liquid. Here, as... Figure 1 As shown, at least a portion of the fourth conduit 40 is vertically arranged.

[0055] In embodiments of this application, to further improve the safety, operability, and pipeline integration of the filter integrity detection system, such as... Figure 1 As shown, the filter integrity testing system of this application also includes a fifth pipeline 50 and a fourth valve 140; wherein, the third port of the respirator 200 is connected to the drain section 600 through the fifth pipeline 50; the second end of the fourth pipeline 40 is connected to the fifth pipeline 50, and the fourth valve 140 is disposed in the fifth pipeline 50 and located between the second end of the fourth pipeline 40 and the respirator 200. Figure 2 As shown, when the filter element is wetted, the fourth valve 140 is opened, and the liquid discharged from the third port flows through the fifth pipe 50 to the drain section 600. Figure 3 As shown, when the filter element is wetted and excess liquid is discharged, the liquid flowing from the fourth pipe 40 converges into the fifth pipe 50 and is discharged together into the drain section 600. At least a portion of the fifth pipe 50 is vertically arranged.

[0056] In the embodiments of this application, such as Figure 1 As shown, the filter element integrity detection system of this application also includes a fifth valve 150, which is disposed in the third pipeline 30. In this embodiment, the specific models of the first valve 110, the second valve 120, the third valve 130, the fourth valve 140, and the fifth valve 150 can be set according to requirements.

[0057] For example, in this embodiment, the first valve 110, the second valve 120, the third valve 130, the fourth valve 140, and the fifth valve 150 are all manual valves. Manual valves are not only easy to operate but also low in cost. Furthermore, the first valve 110 is a manual diaphragm valve, while the second valve 120, the third valve 130, the fourth valve 140, and the fifth valve 150 are all manual ball valves. The difference between diaphragm valves and ball valves lies in their cleanliness. Because of their different constructions, the valve types can be modified according to the system's cleanliness requirements. Since the first valve 110 is close to the purified water source 300, this application requires a manual diaphragm valve with high cleanliness requirements for the first valve 110. Additionally, the dimensions of the four-way connector 900 and the third pipeline 30 should meet the 3D standard requirements to further improve cleanliness.

[0058] In the embodiments of this application, such as Figure 1As shown, the filter element integrity detection system further comprises a pneumatic multi-channel diaphragm valve 170. The pneumatic multi-channel diaphragm valve 170 comprises a first interface, a second interface and a third interface; the second port of the respirator 200 is connected to the first interface, the second interface is used to connect to the external system device 700, and the third interface is connected to the drain 600 through the sixth pipeline 60. Specifically, as shown in Figure 1 As shown, the multi-channel diaphragm valve 170 is composed of a first pneumatic diaphragm valve 171 and a second pneumatic diaphragm valve 172, wherein the first pneumatic diaphragm valve 171 is used to connect to the external system device 700, and the second pneumatic diaphragm valve 172 is connected to the drain 600 through the sixth pipeline 60. It should be noted that the pneumatic multi-channel diaphragm valve 170 is a whole component of prior art (which can be purchased from GEMI / Baodi), and the use of the pneumatic multi-channel diaphragm valve 170 can further improve the cleanliness of the whole system.

[0059] Further, as shown in Figure 1 As shown, the filter element integrity detection system of the present application further comprises a pneumatic ball valve 160 and a pressure gauge 800 to work with the external system device 700 when connected to the external system device 700. Specifically, the top of the respirator 200 is further provided with a fourth port, which is connected to the pneumatic ball valve 160 and the pressure gauge 800; when the second interface (first pneumatic diaphragm valve 171) of the pneumatic multi-channel diaphragm valve 170 is connected to the external system device 700, the first interface of the pneumatic multi-channel diaphragm valve 170 is in communication with the second interface (first pneumatic diaphragm valve 171), and the pneumatic ball valve 160 is opened. In this embodiment, the external system device 700 can be a purified water system or a water for injection distribution system.

[0060] The working state of the filter element integrity detection system of the present application when connected to the external system device 700 will be described below.

[0061] When the filter element integrity detection system of the present application is connected to the external system device 700 and normally operated: the first pneumatic diaphragm valve 171, the pneumatic ball valve 160 and the respirator are opened, and the first valve 110, the second valve 120, the third valve 130, the fourth valve 140 and the fifth valve 150 are closed.

[0062] When the filter element integrity detection system of the present application is performing integrity detection:

[0063] Filter element wetting process: the purified water source 300, the first valve 110, the fourth valve 140 and the fifth valve 150 are opened, and the remaining valves are closed.

[0064] After wetting, the liquid discharge process is carried out: the third valve 130, the fourth valve 140 (the fourth valve 140 is not the main liquid discharge), the fifth valve 150 and the second pneumatic diaphragm valve 172 are opened, and the remaining valves are closed to ensure that there is no residual medium in the pipeline.

[0065] Integrity test process: the compressed air source 400, the integrity tester 500, the second valve 120 and the fifth valve 150 are opened, and the remaining valves are closed.

[0066] In addition, it is worth mentioning that, in the embodiment of the present application, as shown in Figure 1 The filter element integrity detection system further comprises a first preset joint 191 and a second preset joint 192. The first end of the first pipeline 10 is connected with the first preset joint 191, and the first preset joint 191 is used to be connected with the purified water source 300. The first end of the second pipeline 20 is connected with the second preset joint 192, and the second preset joint 192 is used to be connected with the integrity tester 500.

[0067] That is to say, all the structures (including equipment and pipelines) of the present application constitute an integrated module, which only needs to reserve the interfaces (the first preset joint 191 and the second preset joint 192) for integrity detection to be connected with the purified water source 300 and the integrity tester 500. As an example, the first preset joint 191 and the second preset joint 192 are both chucks. The integrated module can be directly connected with the purified water source 300 and the integrity tester 500 in the form of chuck connection. In addition, in the embodiment, since the purified water source 300 is far away from the first preset joint 191, the purified water source 300 can be connected with the first preset joint 191 through the seventh pipeline 70 and the hose 80.

[0068] In summary, the filter element integrity detection system of the present application can detect the integrity of the filter element online, only needs to reserve the first preset joint 191 and the second preset joint 192, and only needs to open the switch during detection. The detection process is simple and does not need to be operated by the operator. The system is closed and has no external interference, which guarantees the cleanliness of the system, and has strong applicability and practicability. In addition, data transmission and recording can be completed. In addition, the filter element integrity detection system of the present application can be applied to various filter element integrity detection systems in the form of an integrated module, especially in the pharmaceutical industry system.

[0069] In summary, compared with the prior art, the present application reduces the process of system installation and greatly reduces the time required for detection.

[0070] For systems that need to detect the integrity of the filter element regularly, the present application reduces external interference factors and is suitable for various systems that need to detect the integrity of the filter element.

[0071] The detection process data of the present application can be recorded and transmitted, and the practical process has no dead angle and dead water problems.

[0072] Finally, it should be noted that the above-described embodiments are merely specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, but not to limit the same, and the protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that any person skilled in the art can make modifications or easily think of changes to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some of the technical features within the technical range disclosed by the present application, and these modifications, changes or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and all should be covered within the protection scope of the present application.
