Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid storage bag testing, in particular to a test tool for disposable 2D liquid storage bags. BACKGROUND

[0002] Disposable 2D liquid storage bags play an important role in the biopharmaceutical field due to their aseptic, sealed, convenient and customizable characteristics. Disposable 2D liquid storage bags may be damaged during manufacturing, transportation or operation, and therefore need to be tested for integrity before use to detect problems early and reduce the risk of product rejection.

[0003] In the prior art, a disposable 2D liquid storage bag is tested for integrity by a integrity tester. During the test, the integrity tester inflates and pressurizes the disposable 2D liquid storage bag, causing the liquid storage bag to expand and pressurize to a preset pressure, and maintain the pressure for a period of time during which the integrity tester can obtain pressure change data. In the prior art, the liquid storage bag often needs to be forced to expand to the maximum volume state during pressurization, increasing the pressurization time of the liquid storage bag and reducing the efficiency of the integrity test of the liquid storage bag. Therefore, further improvement is needed. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the efficiency of the integrity test of the liquid storage bag, the present application provides a test tool for disposable 2D liquid storage bags.

[0005] The test tool for disposable 2D liquid storage bags provided by the present application adopts the following technical solution:

[0006] A test tool for disposable 2D liquid storage bags, comprising a bottom plate, a pair of limiting tool seats fixedly connected to both sides of the bottom plate, and a storage plate fixedly connected between the two limiting tool seats, the storage plate being for placing the integrity tester, the limiting tool seat having a limiting cavity for placing the disposable 2D liquid storage bag, and the upper end face of the limiting tool seat being provided with a test port communicating with the limiting cavity.

[0007] By adopting the above technical solution, when testing the integrity of the disposable 2D liquid storage bag, the disposable 2D liquid storage bag is placed in the limiting cavity from the test port, and the integrity tester inflates and pressurizes the disposable 2D liquid storage bag. Since the liquid storage bag is limited by the limiting cavity, the liquid storage bag can be inflated tightly in the limiting cavity without expanding to the maximum volume state. On the one hand, the pressurization time of the liquid storage bag is effectively reduced, the efficiency of the integrity test of the liquid storage bag is improved, the sensitivity of the test method is increased, and on the other hand, the sealing strength pressure capacity of the liquid storage bag is increased, so that the liquid storage bag can be tested at a higher pressure without worrying about peeling or breaking the seal.

[0008] Preferably, the outer wall of the limiting tool seat is provided with a mounting bracket, and the mounting bracket is provided with a fixing clamp for fixing the test pipeline.

[0009] By adopting the above technical scheme, the fixing clamp on the mounting bracket can stably fix the test pipeline, thereby reducing the influence of pipeline loosening on the accuracy of test results during the test.

[0010] Preferably, the limiting tool seat comprises a limiting outer frame with an open upper portion and fixedly connected to the upper end face of the bottom plate, and a partition plate fixedly connected to the middle of the inner wall of the bottom of the limiting outer frame, and the partition plate divides the inner cavity of the limiting outer frame into two independent limiting cavities.

[0011] By adopting the above technical scheme, the partition plate divides the inner cavity of the limiting outer frame into two independent limiting cavities, so that each liquid storage bag can be tested in an independent limiting cavity, avoiding mutual interference and improving the accuracy and reliability of the test.

[0012] Preferably, the inner wall of the limiting outer frame is provided with a first constraint plate, and the side wall of the partition plate is provided with a second constraint plate, and the first constraint plate and the second constraint plate are both porous plates with pore structures.

[0013] By adopting the above technical scheme, the first constraint plate and the second constraint plate are both porous plates with pore structures, which effectively reduces the contact between the wall of the liquid storage bag and the inner wall of the limiting cavity in the pressure decay test method, thereby preventing the leakage hole from being blocked or reducing the leakage rate and improving the test precision.

[0014] Preferably, the first constraint plate is fixedly connected to the inner wall of the limiting outer frame, the second constraint plate is slidingly connected to the partition plate, and the partition plate is provided with an adjusting member for adjusting the sliding position of the second constraint plate.

[0015] By adopting the above technical scheme, the design of the adjusting member allows the user to adjust the position of the second constraint plate according to actual needs, thereby adjusting the distance between the first constraint plate and the second constraint plate and adjusting the volume of the limiting cavity.

[0016] Preferably, the adjusting member is an adjusting screw rotatably penetrating the limiting outer frame and the first constraint plate, the end portion of the adjusting screw is rotatably connected to the partition plate, and the adjusting screw is threadedly penetrating the second constraint plate.

[0017] By adopting the above technical scheme, the adjusting screw can accurately adjust the position of the second constraint plate, thereby changing the size of the space in the limiting cavity.

[0018] Preferably, the limiting tool seat is provided with a handle.

[0019] By adopting the technical scheme, the limiting tool seat is provided with the handle, the operator can carry and move the whole test tool conveniently, and the portability and operation convenience of the equipment are improved.

[0020] Preferably, the lower end surface of the bottom plate is rotationally connected with the moving caster.

[0021] By adopting the technical scheme, the lower end surface of the bottom plate is rotationally connected with the moving caster, so that the test tool is more convenient and fast to move between different positions, and the operation flexibility and working efficiency of the equipment are improved.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. When testing the integrity of the disposable 2D liquid storage bag, the disposable 2D liquid storage bag is placed into the limiting cavity through the test opening, and then the integrity tester is used to inflate and pressurize the disposable 2D liquid storage bag. Since the liquid storage bag is limited by the limiting cavity, the liquid storage bag can be inflated in the limiting cavity without expanding to the maximum volume, on the one hand, effectively reducing the pressurization time of the liquid storage bag, improving the integrity test efficiency of the liquid storage bag, and increasing the sensitivity of the test method, on the other hand, increasing the sealing strength pressure capacity of the liquid storage bag, so that the liquid storage bag can be tested at a higher pressure without worrying about peeling or breaking the seal;

[0024] 2. The first constraint plate and the second constraint plate are both porous plates with pore structures. In the pressure decay test method, the contact between the liquid storage bag wall and the inner wall of the limiting cavity is effectively reduced to cause leakage hole blockage or reduce the leakage rate, and the test accuracy is improved;

[0025] 3. The design of the adjusting member allows users to adjust the position of the second constraint plate according to actual needs, thereby adjusting the distance between the first constraint plate and the second constraint plate, and adjusting the volume of the limiting cavity.
