Description

Technical Field

[0001] The utility model relates to the technical field of vaporized hydrogen peroxide sterilization, in particular to a vaporized hydrogen peroxide sterilization chemical indicator card. Background Art

[0002] With the country's emphasis on the quality management standards for pharmaceutical production, and the advantages of vaporized hydrogen peroxide sterilization technology (it has no side effects, residues, is rapid, easy to certify, and reliable. It is an ideal disinfection method to replace formaldehyde disinfection at this stage. It has broad development prospects and is also the development trend of space disinfection in the future), more and more pharmaceutical companies pay attention to the monitoring of vaporized hydrogen peroxide sterilization effects.

[0003] However, the current method of judging whether the sterilization effect is qualified by comparing with standard colors or comparison cards is highly subjective. Different people get different results through color judgment, which is prone to misjudgment. Utility Model Content

[0004] In view of the above shortcomings in the prior art, the purpose of the utility model is to provide a vaporized hydrogen peroxide sterilization chemical indicator card, which adopts a combination of gradient contrast color and color-changing indicator color. When the color-changing indicator color is consistent with the gradient contrast color, a uniform "arrow" pattern is formed. When the arrow indicates the qualified area (the third or fourth area), it means that the sterilization is qualified. This avoids the use of standard color or comparison card comparison to judge whether the sterilization effect is qualified, which is highly subjective and prone to misjudgment or difficult to judge.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The vaporized hydrogen peroxide sterilization chemical indicator card comprises a card body, on which a sterilization mark, a text information area and a text description area are arranged, and between the text information area and the text description area, a gradient contrasting color area 1, a gradient contrasting color area 2, a gradient contrasting color area 3 and a gradient contrasting color area 4 are arranged in sequence, the gradient contrasting color area 1 is located on a side close to the sterilization mark, and the gradient contrasting color area 3 and the gradient contrasting color area 4 are both provided with color-changing indicator color areas.

[0007] The gradient contrasting color zone one, the gradient contrasting color zone two, the gradient contrasting color zone three, and the gradient contrasting color zone four are all different. The color-changing indicator color zone is coated with color-changing ink. Before sterilization is performed, the color of the color-changing indicator color zone is consistent with that of the gradient contrasting color zone one, forming an "arrow" pattern in the gradient contrasting color zone one. As sterilization proceeds, the color of the ink in the color-changing indicator color zone changes accordingly. When the ink color is consistent with that of the gradient contrasting color zone three or the gradient contrasting color zone four, that is, when an "arrow" pattern is formed in the gradient contrasting color zone three or the gradient contrasting color zone four, it indicates that the sterilization is qualified.

[0008] The text information area is located above the gradient contrasting color area, and the text description area is located below the gradient contrasting color area.

[0009] The first gradient contrasting color area and the second gradient contrasting color area are both provided with a color changing indicating color area.

[0010] The back of the card body is provided with a text recording area, both sides of the text recording area are provided with adhesive areas, and the card body is provided with threading holes.

[0011] A protective film is arranged above the card body, and a dust removal sticker is arranged above the protective film.

[0012] An electrostatic sticker is arranged under the card body.

[0013] The first gradient contrasting color area, the second gradient contrasting color area, the third gradient contrasting color area, and the fourth gradient contrasting color area are all in the shape of an "arrow".

[0014] The "arrow" shape also serves to indicate direction.

[0015] Vaporized hydrogen peroxide sterilization chemical indicator cards are preferably used for space sterilization.

[0016] The working principle of the utility model is:

[0017] Before sterilization begins, observe whether there is a suitable surface for pasting the indicator card. If not, it can be fixed through the threading hole. If there is a surface that can be pasted, remove the dust removal sticker and dust the area to be pasted. After the dust removal is completed, stick the static sticker on it; remove the protective film, start sterilization, observe the changes in the "arrow" and judge the sterilization effect. Among them, the gradient contrast color area 1, the gradient contrast color area 2, the gradient contrast color area 3, and the gradient contrast color area 4 are all different. The color-changing indicator color area is coated with color-changing ink. When sterilization is not performed, the color of the color-changing indicator color area is consistent with that of the gradient contrast color area 1, and an "arrow" pattern is formed in the gradient contrast color area 1. As the sterilization proceeds, the color of the ink in the color-changing indicator color area changes accordingly. When the ink color is consistent with the gradient contrast color area 3 or the gradient contrast color area 4, that is, when an "arrow" pattern is formed in the gradient contrast color area 3 or the gradient contrast color area 4, it indicates that the sterilization is qualified.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The vaporized hydrogen peroxide sterilization chemical indicator card of the utility model adopts a combination of a gradient contrast color and a color-changing indicator color. When the color-changing indicator color is consistent with the gradient contrast color, an "arrow" pattern with uniform color is formed. When the arrow indicates the qualified area (the third or fourth area), it indicates that the sterilization is qualified. This avoids judging whether the sterilization effect is qualified by comparing with a standard color or a comparison card, which is highly subjective and prone to misjudgment or difficulty in judgment.
