Embodiment Construction

[0061] In order to further understand the content, features and effects of the present invention, the following examples are given, and detailed descriptions are given below with reference to the accompanying drawings.

[0062] Syringe filter: A filter that usually has a female luer lock inlet and a male luer slip or male luer lock outlet.

[0063] Bubble point value: Bubble point is an important indicator of the integrity of the filter, used to detect the integrity of the filter; when the measured bubble point value of the filter is higher than the bubble point limit of the filter, it means that the filter is intact , No damage.

[0064] The application of the present invention will be further described below in conjunction with specific analysis.

[0065] The embodiment of the present invention provides a portable method for manually pressurizing the bubble point value of a syringe filter. The portable method for manually pressurizing the bubble point value of a syringe fil...

Abstract

The invention belongs to the technical field of medical instruments, and discloses a convenient-to-carry device and a method for testing a bubble point value of a needle filter by manual pressurizing.The device comprises an injector, an air pressure meter and the needle filter, wherein the injector is connected with the air pressure meter through a pipeline; the air pressure meter is connected with the needle filter through a pipeline; a thread is formed in one side of the pipeline; and a bayonet is arranged on the other side of the pipeline. The core of the invention is a manual pressurizingdevice, and compressed air is manually generated, so that the integrity of the needle filter can be conveniently detected without an external air source; the external compressed air source can be used, so that a user also can finish testing autonomously on site; the manual pressurizing device is arranged to generate the compressed air, so that the integrity and the performance of the needle filter can be detected; and a tool is simple in using step, detachable and convenient to daily use or carry.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and in particular relates to a portable device and method for manually pressurizing the bubble point value of a syringe filter. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] There are existing methods for testing the bubble point value of syringe filters. For users of small filter products, the bubble point test is a simple and easy test method, and the bubble point test is based on the capillary model. The structure of the filter membrane is full of microporous flow channels, which is the basic unit of filtration. These microporous flow channels are like many "capillaries". When the filter membrane is completely wetted by the wetting liquid, the liquid is retained inside the "capillary" by the action of surface tension. If you want to squeeze the liquid out of the membrane hole, you need Add a gas pressure ...
