Description

Technical Field

[0001] The utility model relates to the field of medical device sterilization, in particular to a sterilization indicator card. Background Art

[0002] In a laboratory environment, it is crucial to ensure the sterility of experimental equipment, culture media and other items. Pressure steam sterilization, as an efficient, reliable and widely used sterilization method, can kill various microorganisms, including bacteria, spores and fungi, through high-temperature and high-pressure steam. In order to verify whether each pressure steam sterilization process has truly achieved effective sterilization conditions, sterilization indicator cards came into being.

[0003] The sterilization indicator card can intuitively reflect whether the items have undergone the appropriate pressure steam sterilization process through its unique chemical indicator. During the sterilization process, the chemical substances on the indicator card will undergo specific color changes according to factors such as temperature, pressure and time. In some sterilization indicator cards, they appear light blue when not sterilized, and turn dark black after successful pressure steam sterilization. Through the indicator card, experimenters can quickly and conveniently determine whether the sterilization is qualified.

[0004] Generally, sugar-containing culture media will undergo a certain degree of caramelization when the temperature is too high during sterilization, and the sugar will decompose and carbonize. Therefore, for sugar-containing culture media, the standard stipulates that sterilization should be carried out at 115 degrees Celsius for 20 minutes. Currently, there is no simple sterilization indicator card for monitoring the sterilization effect of 115 degrees Celsius low-temperature steam, only biological indicators. The operation of such indicators is complicated and the price is relatively high. Therefore, a sterilization indicator card is proposed to solve the above problems. Utility Model Content

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figure 1 - Figure 3 , an embodiment provided by the present invention: a sterilization indication card, including a card body base layer 1, a color-changing ink area 2 is fixedly connected to the top of the card body base layer 1, a color-changing indication ink of 115 °C is coated on the color-changing ink area 2, the starting color and the ending color are different, an adhesive area 6 is fixedly connected to the bottom of the card body base layer 1, an information recording area 4 is arranged on the top of the card body base layer 1, a pressure steam comparison area 3 is arranged on the top of the card body base layer 1, a waterproof component is arranged on the top of the card body base layer 1, the waterproof component is used to prevent the color-changing ink area 2 from getting damp, the waterproof component includes a waterproof film 5, the top of the card body base layer 1 is fixedly connected to the bottom of the waterproof film 5, the card body base layer 1 is a waterproof and high-temperature resistant adhesive label paper, the shape is rectangular, the ink used in the color-changing ink area 2 will only change color after reaching 115 °C, and this color change is irreversible;

[0023] Specifically, when using the sterilization indicator card to monitor the sterilization process, first place the sterilization indicator card at an appropriate position inside the sterilization device. After placement, start the sterilization device and operate according to the established sterilization procedure. After the sterilization operation is completed, take out the sterilization indicator card from the sterilization device. After taking it out, immediately check the indicator card. During the check, focus on observing the color changes in the color-changing ink area 2 and the pressure steam comparison area 3. The colors of these two areas are preset before sterilization for easy comparison after sterilization. If the color of the color-changing ink area 2 is the same as the color of the pressure steam comparison area 3, then it can be considered that the sterilization process is qualified, that is, the sterilization device has reached the predetermined temperature and pressure, and the sterilization effect meets the standard. However, if the color of the color-changing ink area 2 is different from the color of the pressure steam comparison area 3, this indicates that the sterilization device has not reached the specified temperature or pressure, resulting in an incomplete sterilization process and a potential risk of sterilization failure. In this case, it is necessary to re-check the settings and operation process of the sterilization device to ensure that all parameters meet the sterilization requirements. After sterilization is completed, if the indicator card shows that the sterilization is qualified, the adhesive area 6 on the back of the card body base layer 1 can be torn off. After tearing off the protective layer of the adhesive area 6, relevant sterilization information can be recorded in the information recording area 4, including the sterilization date, the model of the equipment used, and the operation method, etc. Recording this information helps to trace the sterilization process and ensure the traceability and quality control of the sterilization operation. After recording, the indicator card can be pasted on the corresponding record document for long-term storage and reference. In this way, the sterilization indicator card can not only help confirm whether the sterilization process is successful, but also provide detailed sterilization records, providing strong support for the sterilization quality control of medical institutions or laboratories.

[0024] Refer to Figure 1 - Figure 3 At the top of the card body base layer 1, a snap ring 7 is fixedly connected. Inside the snap ring 7, a suspension rope 8 is arranged. One end of the suspension rope 8 is fixedly connected to a first fixing block 9, and the other end of the suspension rope 8 is fixedly connected to a second fixing block 10. The second fixing block 10 is internally threaded onto the outer wall of the first fixing block 9;

[0025] Specifically, for some items whose surfaces cannot directly paste sterilization indicator cards, such as certain metal surfaces or smooth plastic products, a specially designed fixing mechanism can be adopted to ensure the correct suspension of the sterilization indicator card. First, it is necessary to rotate the first fixing block 9. This action will loosen the connection between the first fixing block 9 and the second fixing block 10, allowing them to separate. This design enables the first fixing block 9 and the second fixing block 10 to move independently, providing the necessary space and flexibility for suspending the sterilization indicator card. Once the first fixing block 9 and the second fixing block 10 are separated, the next step is to suspend or bind the sterilization indicator card to the item to be sterilized, ensuring that the indicator card can be firmly attached to the item so that it can accurately reflect the sterilization effect during the sterilization process. After the suspension is completed, the operator needs to rotate the first fixing block 9 back into the interior of the second fixing block 10. This action will re-lock the first fixing block 9 and the second fixing block 10, ensuring that they are tightly combined together, thereby fixing the sterilization indicator card. In this way, even if the item surface cannot be directly pasted, the sterilization indicator card can be safely fixed to the item and will not fall off or shift during the sterilization process.

[0026] Working principle: When using this sterilization indicator card, first place the sterilization indicator card into the sterilization device for sterilization operation. After the sterilization is completed, take out the sterilization indicator card and compare the colors of the color-changing ink area 2 and the pressure steam comparison area 3. If the colors are the same, it is qualified; if the colors are different, it means that the sterilization device has not reached a certain temperature, resulting in incomplete sterilization. After the pressure steam sterilization is completed, the adhesive area 6 on the back of the card body base layer 1 can be torn off. After recording the date, equipment model, and operation method in the information recording area 4, it can be pasted on the record document. For some items that cannot be pasted, the first fixing block 9 can be rotated to separate the first fixing block 9 and the second fixing block 10 first, then the sterilization indicator card can be suspended on the item, and then the first fixing block 9 can be rotated into the interior of the second fixing block 10.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
