Problems solved by technology

[0003] The present invention aims to solve the problems in the prior art that the BD test card or BD test paper used in the BD test is easy to identify, poor in conciseness, and prone to visual fatigue during identification. Therefore, a BD test kit of the present invention is provided. The detection and recognition of the BD test card included in the package is relatively simple, and it is not easy to cause visual fatigue

Embodiment 1

[0023] A kind of BD test bag, has bag, is provided with BD test card in the bag, and described BD test card has a negative film 2, and the color changing frame 1 is attached on this film, and described color changing frame is a plurality of similar rhombuses of different sizes frame, the relatively large frame in the similar diamond-shaped frame is surrounded by the periphery of the relatively small frame, and the height of the relatively small frame in the similar diamond-shaped frame is smaller than the height of the relatively large frame; each frame in the similar rhombus frame The widths of the boxes are equal, and the width is 3mm; the spacing of each frame is equal, and the spacing is 4mm.

Embodiment 2

[0025] The BD test package of this example is different from the above example in that the color-changing frame is a number of similar regular triangle frames of different sizes, and the other structures are the same as the above example.

Embodiment 3

[0027] The BD test package in this example differs from the above example in that the color-changing frames are similar regular pentagonal frames of different sizes, and the other structures are the same as those in Example 1.

Abstract

The invention discloses a BD test pack. The BD test pack is concise in frame line construction, beneficial to recognition test and not prone to visual fatigue during a test. The BD test pack is provided with a pack sleeve. A BD test card is arranged in the pack sleeve. The BD test card is provided with a base substrate (2), color change frames (1) are attached to the base substrate (2), the color change frames (1) are a plurality of frames with similar figures, the smaller frame in the frames with the similar figures is sleeved with the corresponding larger frame in the frames with the similar figures, and the height of the smaller frame in the frames with the similar figures is smaller than that of the corresponding larger frame in the frames with the similar figures. The BD test pack is applicable to testing the forevacuum pressure steam sterilizer vacuum-pumping effect and the steam sterilizing penetration effect.

Description

technical field [0001] The invention relates to a thermosensitive discoloration detection device. Background technique [0002] BD test is a method to detect the vacuum effect of pre-vacuum pressure steam sterilizer and the penetration effect of steam sterilization. Before the sterilization supply department of the hospital performs pressure steam sterilization on various instruments and consumables, it must first conduct an empty pot BD test on the pre-vacuum pressure steam sterilizer to detect the vacuum pumping effect and steam penetration effect of the sterilizer, BD The sterilizer can only sterilize medical devices after passing the test. The BD test usually uses a test card or test paper with a BD diagram printed on a special heat-sensitive indicator ink to display the test results. If the BD diagram changes color (usually from light yellow to black) evenly and thoroughly, it means that the vacuuming effect of the sterilizer is good. If the steam penetration effect i...
