Description

Technical Field

[0001] This disclosure relates to the field of respirator integrity testing technology, and in particular to an online respirator integrity testing device and a portable integrity testing equipment. Background Technology

[0002] In the pharmaceutical manufacturing industry, respirators are core components of critical equipment such as freeze dryers and rubber stopper sterilizers, and the performance of their filters directly affects the reliability of the aseptic production environment. To ensure drug production quality, current regulations require that the integrity of respirator filters be tested before production operations. The relevant technology can be found in the filter integrity testing system disclosed in Chinese Patent CN102109364B.

[0003] However, in actual production scenarios, pharmaceutical companies are equipped with a large number of freeze dryers and rubber stopper machines. Adding a dedicated online integrity detection device for each machine would significantly increase equipment procurement costs. Furthermore, in production workshops with limited space, such as those for freeze dryers or rubber stoppers, a separately installed online integrity detection device would further reduce space utilization and, in severe cases, obstruct pedestrian traffic. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an online integrity testing device and a mobile integrity testing equipment for respirators that reduces equipment procurement costs, ensures normal operation of the testing process, does not reduce the space utilization of the production workshop, improves the adaptability to testing respirators of different heights, and improves testing efficiency.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] An online integrity detection device for respirators, comprising:

[0007] Base;

[0008] A scissor lift platform that can be lifted and lowered on the base;

[0009] A driver, the drive end of which is connected to the scissor lift platform, is used to drive the scissor lift platform to move away from or towards the base.

[0010] The movable wheels are located on the side of the base opposite to the scissor lift platform;

[0011] The integrity tester is installed on the scissor lift platform.

[0012] In one embodiment, the scissor lift includes a support platform, a first outer scissor arm, a second outer scissor arm, a first inner scissor arm, a second inner scissor arm, and a rotating shaft;

[0013] The middle portions of the first outer scissor arm and the first inner scissor arm are rotatably disposed at the first end of the rotating shaft, and the middle portions of the second outer scissor arm and the second inner scissor arm are rotatably disposed at the second end of the rotating shaft; the first ends of the first outer scissor arm and the first ends of the second outer scissor arm are respectively fixedly connected to the base, and the second ends of the first outer scissor arm and the second outer scissor arm are respectively slidably disposed on the side of the support platform facing the base; the first ends of the first inner scissor arm and the first ends of the second inner scissor arm are fixedly connected to the support platform, and the second ends of the first inner scissor arm and the second inner scissor arm are respectively slidably disposed on the base;

[0014] The first end of the driver is slidably disposed on the first outer scissor arm and the second outer scissor arm, and the second end of the driver is slidably disposed on the first inner scissor arm and the second inner scissor arm. The first end of the driver is the driving end.

[0015] In one embodiment, the support platform is recessed inward to form a receiving groove for accommodating the integrity detector.

[0016] In one embodiment, the respirator online integrity detection device further includes a climbing ladder disposed on the base; the support platform also forms a personnel operation area, which is correspondingly disposed to the climbing ladder.

[0017] In one embodiment, the respirator online integrity detection device further includes a fence arranged along the periphery of the support platform, and the fence forms an entrance corresponding to the climbing ladder.

[0018] In one embodiment, the fence also has a cable tray, which is configured to correspond to the cable of the integrity detector.

[0019] In one embodiment, the respirator online integrity detection device further includes a plurality of fixing hooks, each of which is disposed on the inner sidewall of the take-up groove.

[0020] In one embodiment, the integrity detector includes a display unit and a detection body. The display unit is disposed on the detection body, and the detection body has an air inlet, a detection end, an exhaust end, and a power supply end. The detection end is detachably connected to the top of the respirator's filter, and the air inlet of the integrity detector is detachably connected to an external compression tank. The exhaust end is connected to the detection end via a solenoid valve, and the power supply end is connected to an external power source.

[0021] In one embodiment, the number of the movable wheels is four, and the four movable wheels are respectively disposed at the four corners of the base; and / or,

[0022] The actuator is a hydraulic cylinder.

Since the integrity tester is mounted on the scissor lift platform, which can be raised and lowered on the base, and the drive end of the driver is connected to the scissor lift platform, the operator can adjust the position of the scissor lift platform according to the actual application scenario to adapt to different respirator heights, facilitating the installation of the integrity tester and ensuring rapid testing. After testing is completed, the operator can push away the base to remove the online integrity testing device, restoring the space before testing and effectively avoiding the problem of a separately added online integrity testing device interfering with pedestrian traffic due to reduced production space utilization. Furthermore, the added scissor lift platform can meet the testing needs of respirators of different heights, further improving the adaptability of the online integrity testing device for respirators.

[0026] 2) When the next device needs to be tested, the operator can move the base next to the device to be tested and perform lifting and testing operations. This operation can be repeated to meet the testing needs of multiple different respirators, so as to ensure that one respirator online integrity testing device can meet the testing needs of a large number of freeze dryers and rubber stopper machines, thereby reducing equipment procurement costs.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0037] Please refer to 1 to Figure 3 An embodiment of an online ventilator integrity testing device 10 includes a base 100, a scissor lift platform 200, a driver 300, and casters 400, and an integrity testing instrument 500. The scissor lift platform 200 is vertically and vertically mounted on the base 100. The driver end 310 of the driver 300 is drivenly connected to the scissor lift platform 200, and the driver 300 is used to drive the scissor lift platform 200 to move away from or towards the base 100. The casters 400 are disposed on the side of the base 100 opposite to the scissor lift platform 200. The integrity testing instrument 500 is disposed on the scissor lift platform 200.

[0038] It is understandable that, since the casters 400 are located on the side of the base 100 facing away from the scissor lift platform 200, it is convenient for the operator to move the base 100 to the side of the equipment to be tested. Since the integrity tester 500 is mounted on the scissor lift platform 200, the scissor lift platform 200 can be raised and lowered on the base 100. The drive end 310 of the driver 300 is connected to the scissor lift platform 200, allowing the operator to adjust the position of the scissor lift platform 200 to accommodate different respirator heights, facilitating the installation of the integrity tester 500 and ensuring rapid testing. After testing is completed, the operator can push away the base 100 to remove the online integrity testing device, restoring the space before testing and effectively avoiding the problem of the separately added online integrity testing device interfering with pedestrian traffic due to reduced production space utilization. Furthermore, the added scissor lift platform can meet the testing needs of respirators of different heights, further improving the adaptability of the respirator online integrity testing device 10.

[0039] Furthermore, when it is necessary to test the next device, the operator can move the base 100 next to the device to be tested and perform lifting and testing operations. This operation can be repeated to meet the testing needs of multiple different respirators, ensuring that one respirator online integrity testing device 10 can meet the testing needs of a large number of freeze dryers and rubber stopper machines, thereby reducing equipment procurement costs.

[0040] like Figures 1 to 2As shown, in one embodiment, the scissor lift platform 200 includes a support platform 210, a first outer scissor arm 220, a second outer scissor arm 230, a first inner scissor arm 240, a second inner scissor arm 250, and a rotating shaft 260; the middle portions of the first outer scissor arm 220 and the middle portions of the first inner scissor arm 240 are rotatably disposed at the first end of the rotating shaft 260, realizing the rotational arrangement of the first outer scissor arm 220 and the first inner scissor arm 240; the middle portions of the second outer scissor arm 230 and the middle portions of the second inner scissor arm 250 are rotatably disposed at the second end of the rotating shaft 260, realizing the rotational arrangement of the second outer scissor arm 230 and the second inner scissor arm 250; and because the first outer scissor arm 220... The first end of the first scissor fork arm 220 and the first end of the second scissor fork arm 230 are respectively fixedly connected to the base 100. The second ends of the first scissor fork arm 220 and the second scissor fork arm 230 are respectively slidably disposed on the side of the support platform 210 facing the base 100, so as to realize the sliding arrangement of the first scissor fork arm 220, the second scissor fork arm 230 and the support platform 210. The first end of the first scissor fork arm 240 and the first end of the second scissor fork arm 250 are fixedly connected to the support platform 210. The second ends of the first scissor fork arm 240 and the second scissor fork arm 250 are respectively slidably disposed on the base 100, so as to realize the sliding arrangement of the first scissor fork arm 240 and the second scissor fork arm 250 and the base 100.

[0041] It can also be understood that, since the first end of the driver 300 is slidably disposed on the first outer scissor arm 220 and the second outer scissor arm 230, and the second end of the driver 300 is slidably disposed on the first inner scissor arm 240 and the second inner scissor arm 250, and the first end of the driver 300 is the driving end 310, under the action of external force, the two ends of the driver 300 can simultaneously push the first outer scissor arm 220, the second outer scissor arm 230, the first inner scissor arm 240, and the second inner scissor arm 250 to slide, thereby realizing the lifting and lowering of the support platform 210 relative to the base 100.

[0042] In addition, the addition of the first outer scissor arm 220, the second outer scissor arm 230, the first inner scissor arm 240, and the second inner scissor arm 250 can improve the stability and reliability of the support platform 210 during the lifting process.

[0043] like Figures 1 to 2As shown, in one embodiment, the scissor lift platform 200 further includes a first sliding rod 271 and a second sliding rod 272. The second ends of the first outer scissor arms 220 and 230 are respectively slidably disposed on the first sliding rod 271. The two ends of the first sliding rod 271 are respectively slidably disposed on the side of the support platform 210 facing the base 100, so as to realize the sliding arrangement of the second ends of the first outer scissor arms 220 and 230 with the support platform 210. Similarly, the second ends of the first inner scissor arms 240 and 250 are respectively slidably disposed on the first sliding rod 271. The two ends of the first sliding rod 271 are respectively slidably disposed on the base 100, so as to realize the sliding arrangement of the second ends of the first inner scissor arms 240 and 250 with the base 100.

[0044] In one embodiment, the two ends of the first sliding rod 271 are slidably disposed on the support platform 210, and the two ends of the second sliding rod 272 are slidably disposed on the base 100. Since the sliding arrangements of the two ends of the first sliding rod 271 with the support platform 210 and the two ends of the second sliding rod 272 with the base 100 are prior art, they will not be specifically described in this disclosure.

[0045] In one embodiment, the first end of the actuator 300 is slidably mounted on the first outer scissor arm 220 and the second outer scissor arm 230 via a third sliding rod 273, and the second end of the actuator 300 is slidably mounted on the first inner scissor arm 240 and the second inner scissor arm 250 via a fourth sliding rod 274. Both ends of the third sliding rod 273 can be slidably mounted with the first outer scissor arm 220 and the second outer scissor arm 230 via sliding blocks. Similarly, both ends of the fourth sliding rod 274 can be slidably mounted with the first inner scissor arm 240 and the second inner scissor arm 250 via sliding blocks.

[0046] like Figure 3 As shown, in one embodiment, the support platform 210 is recessed inward to form a receiving groove 211, which is used to receive the integrity detector 500 to achieve better fixation of the integrity detector 500 and effectively avoid the problem of the integrity detector 500 easily shifting or falling during the lifting process.

[0047] like Figure 1 and Figure 2As shown, in one embodiment, the respirator online integrity testing device 10 further includes a climbing ladder 600, which is disposed on the base 100; the support platform 210 also forms a personnel operation area 212, which is correspondingly disposed with the climbing ladder 600, so that the operator or assistant can reach the personnel operation area 212 through the climbing ladder 600 to ensure the normal operation of the testing.

[0048] like Figure 1 and Figure 2 As shown, in one embodiment, the respirator online integrity testing device 10 further includes a fence 700, which is arranged along the periphery of the support platform 210, so that the added fence 700 can form a relatively safe testing area with the support platform 210, thereby ensuring the safety of the operator when performing testing on the support platform 210; and the fence 700 forms an entrance 710, which is correspondingly arranged with the climbing ladder 600, so that the operator or assistant can enter the personnel operation area 212 through the entrance 710.

[0049] In one embodiment, the movable wheel 400 is further provided with a locking member, which is used to lock and fix the movable wheel 400 in place, thereby further improving the safety of the operator performing inspections on the platform 210. Since the locking member and the movable wheel 400 are prior art, they will not be described in detail in this disclosure.

[0050] like Figure 4 As shown, in one embodiment, the fence 700 also forms a cable tray 720, which is configured to correspond to the cables of the integrity tester 500, so as to better collect the cables on the multiple ports of the integrity tester 500. On the one hand, this ensures the neatness and aesthetics of the collection, and on the other hand, it facilitates the operator to quickly pick up different types of cables, so as to quickly complete the installation of the integrity tester 500 with the freeze dryer and the rubber stopper machine, thereby improving the testing efficiency.

[0051] In one embodiment, the respirator online integrity detection device 10 further includes a plurality of fixing hooks, each of which is disposed on the inner side wall of the take-up groove 720 to ensure that the wound cable can be better suspended in the take-up groove 720, so as to achieve better collection and fixation of the cable.

[0052] like Figure 2As shown, in one embodiment, the integrity detector 500 includes a display unit 510 and a detection body 520. The display unit 510 is disposed on the detection body 520. The detection body 520 has an air inlet 521, a detection end 522, an exhaust end 523, and a power supply end 524. The detection end 522 is detachably connected to the top of the respirator filter. The air inlet 521 of the integrity detector 500 is detachably connected to an external compression tank to ensure that the detection body 520 and the filter can form a closed detection circuit, thereby ensuring the accuracy of the detection. The exhaust end 523 is connected to the detection end 522 through a solenoid valve to realize the exhaust function of the detection body 520, so as to ensure that the pressure during the detection process can be maintained within the normal range. Furthermore, since the power supply end 524 is connected to an external power source to realize the power-on mode of the detection body 520, the normal operation of the detection is ensured.

[0053] In this embodiment, firstly, the first and third control valves on both sides of the filter are closed, while the second control valve remains unobstructed. Pure water is added to the top of the filter until it is submerged, and the liquid level is observed to ensure no significant drop. Simultaneously, it is ensured that there is no water leakage outside the filter, thus completing the humidification operation. Next, the detection end 522 of the integrity tester 500 is installed to the detection port on the top of the filter. Simultaneously, the air inlet end 521 of the integrity tester 500 is connected to external compressed air. The power is turned on, and the main menu of the integrity tester 500 is accessed. The appropriate filter test program is selected, or the test program is accessed through the program list, and the appropriate filter test program is selected. Relevant information (product batch number, filter serial number, etc.) is entered to start the program. After the filter test is completed, the test results are displayed. Once the test is complete, the second control valve is closed, and the third control valve is opened to drain all the water from inside the filter. After the water is drained, the third control valve is closed, and the first control valve and the steam pipe valve are opened to complete the drying operation of the filter, thereby completing the integrity test of the filter.

[0054] It should be noted that the detection principle of the detection body 520, and the opening and closing of the first control valve, the second control valve, and the third control valve of the control module are all existing technologies. Therefore, they are not described in detail in this disclosure; and they are not within the protection scope of this disclosure. This disclosure only protects the connection method between the detection body 520, the control module, the first control valve, the second control valve, and the third control valve.

[0055] In one embodiment, the number of take-up slots 720 is four.

[0056] In one embodiment, the number of the movable wheels 400 is four, and the four movable wheels 400 are respectively arranged at the four corners of the base 100 to ensure the stability and reliability of the base 100 during the movement process.

[0057] In one embodiment, the driver 300 is a hydraulic cylinder to drive the scissor lift 200 to lift.

[0058] This disclosure also provides a portable integrity testing device, including the respirator online integrity testing device 10 described in any of the above embodiments. The portable integrity testing device includes a compressed gas tank, which is disposed on a base 100 to enable rapid testing of the filter's integrity.

[0059] In one embodiment, a movable integrity testing device is used in a rubber stopper machine. Since the respirator of the rubber stopper machine is typically located at the top, its height is relatively high. While a staircase at the top allows the operator to manually move the integrity testing device to the top for testing, the movable integrity testing device has many components, making it impossible for the operator to complete the operation in one go; several trips are required, thus affecting testing efficiency. Some researchers suggest extending the cable length of the integrity tester 500 to solve this problem. However, limited by the cable length of the integrity tester 500 itself, testing respirators exceeding the cable length still relies on the traditional manual handling method, resulting in slow testing efficiency.

[0060] Therefore, the scissor lift platform 200, driver 300 and casters 400 added in this disclosure can realize faster lifting and lowering operation of the integrity detector 500, thereby improving the rapid detection of high-position respirators, thus improving the detection efficiency and improving the adaptability to the detection of respirators at different heights.

[0061] Compared with the prior art, this disclosure has at least the following advantages:

[0062] 1) Because the casters 400 are located on the side of the base 100 facing away from the scissor lift platform 200, it is convenient for the operator to move the base 100 to the side of the equipment to be tested. Since the integrity tester 500 is mounted on the scissor lift platform 200, the scissor lift platform 200 can be raised and lowered on the base 100. The drive end 310 of the driver 300 is connected to the scissor lift platform 200, allowing the operator to adjust the position of the scissor lift platform 200 to accommodate different respirator heights, facilitating the installation of the integrity tester 500 and ensuring rapid testing. After testing, the operator can push away the base 100 to remove the online integrity testing device, restoring the space before testing and effectively avoiding the problem of the separately added online integrity testing device interfering with pedestrian traffic due to reduced production space utilization. Furthermore, the added scissor lift platform can meet the testing needs of respirators of different heights, further improving the adaptability of the respirator online integrity testing device 10.

[0063] 2) When the next device needs to be tested, the operator can move the base 100 to the device to be tested and perform lifting and testing operations. This operation can be repeated to meet the testing needs of multiple different respirators, so as to ensure that one respirator online integrity testing device 10 can meet the testing needs of a large number of freeze dryers and rubber stopper machines, thereby reducing equipment procurement costs.

[0064] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
