Description

Technical Field

[0001] The utility model relates to the technical field of chemical indicator cards, in particular to a reagent kit type chemical indicator card. Background Art

[0002] According to national regulations on the sterilization of medical devices, hospital medical staff are required to place the corresponding chemical indicator card at the same time when sterilizing the instrument each time, and observe the color change of the indicator card to facilitate medical staff to judge whether the set sterilization parameters have been achieved.

[0003] However, the current method of judging whether the sterilization effect is qualified by comparing with standard colors or comparison cards is not able to monitor the sterilization temperature, which is highly subjective. Different people get different results through color judgment, which is prone to misjudgment. 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 deficiencies in the prior art, the purpose of the utility model is to provide a reagent kit type chemical indicator card to avoid using standard colors or comparison cards to judge whether the sterilization effect is qualified, which is highly subjective and prone to misjudgment or difficulty in judgment.

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

[0006] The reagent kit type chemical indicator card comprises an indicator card and a transparent polytetrafluoroethylene shell. The indicator card is located inside the transparent polytetrafluoroethylene shell. A detection area is provided on the indicator card. A temperature-variable ink area C and an indicator ink area T are provided on the detection area. A shell area S is provided on the transparent polytetrafluoroethylene shell. The indicator ink area T is located on a side close to the shell area S.

[0007] Transparent closed polytetrafluoroethylene shell, with shell S area on top for sterilization factors to enter the shell and contact indicator card.

[0008] The indicator card is provided with a text description area C and a text description area T. The text description area C is located on a side close to the temperature-variable ink area C, and the text description area T is located on a side close to the indicator ink area T.

[0009] The back of the instruction card is provided with a text recording area.

[0010] An ink protection film is arranged above the indicator card, and a bottom surface protection film is arranged below the indicator card.

[0011] An inclined guide plate is arranged below the transparent polytetrafluoroethylene shell, and the inclined guide plate is located below the indicator card.

[0012] An impurity outlet is arranged on the vertical surface of the transparent polytetrafluoroethylene shell. The impurity outlet is located on the side away from the S area of ​​the shell. The bottom edge of the impurity outlet is tangent to the bottom surface of the transparent polytetrafluoroethylene shell.

[0013] Structural principle: This structure consists of an indicator card, which has a temperature-variable ink zone C printed with temperature-variable ink. When the sterilization temperature is reached, the color changes from colorless to red; the indicator card has an indicator ink zone T printed with indicator ink. When the concentration of the sterilization factor reaches this zone, the indicator ink changes from red to colorless at sufficient sterilization time and appropriate sterilization temperature.

[0014] Figure 4 , only when the line comes out from area C, the color change sterilization is qualified; Figure 3 , C / T are both out of line, indicating that the sterilization temperature is qualified, the penetration of the sterilization factor is unqualified, and the sterilization fails; Figure 5 , C / T have no lines, it means that the sterilization temperature is unqualified, the penetration of the sterilization factor is qualified, and the sterilization fails.

[0015] Structural features: The main difference between this structure and the indicator cards of other manufacturers is that the sterilization factor passes through the S area of ​​the shell and reaches the inside of the test box. Only when the temperature-changing ink C area comes out, the color change sterilization is qualified. If both C / T come out, it means that the sterilization temperature is qualified and the sterilization factor penetration is unqualified. If both C / T do not come out, it means that the sterilization temperature is unqualified and the sterilization factor penetration is qualified, and both are sterilization failures.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] With the reagent kit type chemical indicator card of the utility model, the sterilization factor passes through the S area and reaches the inside of the test box. Only when the C area comes out, the color changes and the sterilization is qualified. If both C / T come out, it means that the sterilization temperature is qualified and the sterilization factor penetration is unqualified. If both C / T do not come out, it means that the sterilization temperature is unqualified and the sterilization factor penetration is qualified, both of which are sterilization failures. It is more intuitive to judge whether the sterilization is qualified, reduce misjudgment caused by subjective factors, and is more convenient for customers to use. BRIEF DESCRIPTION OF THE DRAWINGS
