[0008] The problem with the above patent is that a removable sealing plug needs to be provided at one end of the sterilization chamber, which has a complex structure and high production cost. The force-resistant hollow tube surrounds the outer periphery of the hollow tube support part, which is easy to sterilize and cannot ensure that the sterilization effect of the instrument meets the standard. Utility Model Content

[0009] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a visual hydrogen peroxide sterilization verification device with a simple structure and reduced production costs. The sterilization effect is verified by simulating the most difficult sterilization state, thereby improving the reliability of verification and achieving the purpose of batch release.

By setting up a circular resistance hollow tube, the sterilization effect is verified by simulating the most difficult to sterilize state, thereby achieving the purpose of batch release.

[0012] Adhesive is arranged on both sides of the partition. The two shells are respectively adhered to the two sides of the partition, and the two shells are combined together by adhesion, which is convenient for production and reduces production costs.

[0013] The longitudinal section of the cabin is a rectangle, and the length direction of the cabin is consistent with the length direction of the shell. The cabin is set in a rectangular shape and the length direction is consistent with the length direction of the shell, which increases the volume of the cavity and reserves enough space for the direction of the resistance hollow tube.

[0014] The indicator is a chemical indicator, a biological indicator, or a chemical indicator and a biological indicator. A chemical indicator can be placed for chemical monitoring, a biological indicator can be placed for biological monitoring, or both a chemical indicator and a biological indicator can be placed for chemical monitoring and biological monitoring at the same time.

[0015] The cavity is a visual setting. After sterilization, the color change of the chemical indicator is observed, or the color change of the biological indicator is observed after culturing, so as to quickly and accurately judge the sterilization effect of the lumen instrument or other instruments.
