no. 1 example

[0035] see figure 1 , the sterilization detection device provided in this embodiment is used for B-D testing, and it includes a plurality of hydrophobic non-woven fabrics 2, wherein the plurality of hydrophobic non-woven fabrics 2 are divided into upper and lower parts (2a, 2b), Indicator 1a is B-D test paper, which generally includes blotting paper, B-D test paper and air-impermeable paper, etc. The indicator 1a is arranged between the upper and lower parts (2a, 2b) of the above-mentioned hydrophobic non-woven fabric, and is located near the middle of the hydrophobic non-woven fabric, so that the upper and lower parts (2a, 2b) ) when stacked together, the indicator 1a can be covered therein.

[0036] In this embodiment, the sterilization detection device also includes a fixing component, which is used to clamp and fix a plurality of hydrophobic non-woven fabrics 2, so as to reduce the gap between the hydrophobic non-woven fabrics 2, so that the indicator can be tightly wrapp...

no. 2 example

[0042] see image 3 , The sterilization detection device provided in this embodiment is used for chemical PCD. Compared with the first embodiment above, the only difference is that the indicator 1b is a chemical indicator PCD. The manner in which the indicator 1b is covered by the hydrophobic non-woven fabric 2 is the same as that of the first embodiment above, and will not be repeated here.

no. 3 example

[0044] see Figure 4 The sterilization detection device provided in this embodiment is used for biological PCD. Compared with the first embodiment above, the only difference is that the indicator 1c is a biological indicator PCD.

[0045] In addition, a closed hollow portion 2 c is formed in a part of the hydrophobic nonwoven fabrics located near the middle of the plurality of hydrophobic nonwoven fabrics 2 . Specifically, a closed hollow part 2c is formed at the middle position of the lower part 2b of the hydrophobic nonwoven fabric, and a biological indicator PCD is disposed in the hollow part 2c. It is easy to understand that part of the bottom hydrophobic nonwoven fabric in the lower part 2b of the hydrophobic nonwoven fabric is not provided with the hollow part 2c, so as to realize the sealing of the hollow part 2c.

[0046] The color change of the test object of the sterilization detection device provided by the above-mentioned various embodiments of the present inventi...

Abstract

The invention provides a sterilization detection device which comprises multiple hydrophobic non-woven fabrics and an indicator; multiple hydrophobic non-woven fabrics are overlaid together and coat the indicator. The sterilization detection device provided by the invention can be repeatedly used, so that the device cost can be lowered, and environmental pollution can also be avoided.

Description

technical field [0001] The invention relates to the technical field of sterilization detection, in particular to a sterilization detection device. Background technique [0002] In hospital disinfection and sterilization work, in order to ensure the quality of sterilization, some comforters are usually used to monitor the sterilization effect. In addition to recording conventional temperature, pressure, and time, sterilization testing can also be performed by chemical and biological methods. A device for sterilization monitoring is generally called a process challenge device (hereinafter referred to as PCD). The structure of the PCD device can be various, as long as it can provide a certain resistance to the penetration of the sterilizing medium, so that the sterilizing medium does not easily enter the PCD device. In addition, to verify the vacuum degree of the sterilization chamber, that is, to verify the residual air in the sterilization chamber, it is generally verified ...
