Embodiment 1

[0079] Example 1: Lumen Process Challenge Test Tubes

[0080] prepared as figure 1 The lumen-type process challenge test tube is shown, wherein the tube body is made of polycarbonate material with a thickness of 3 mm, the length of the cavity where the vapor damping structure is placed is 52 mm, and the inner diameter is 18 mm. The vapor damping structure is in the form of interleaved laminations made of polycarbonate material. Figure 8 It is a schematic diagram of a lamination used in Example 1. The diameter of the lamination is 18mm, and the thickness is 2mm. There are 8 laminations in total. The distance between the laminations is 4mm, and the distance between the open end and the pipe body is 11mm. The inner diameter of the end is 2mm. The cross-section of the laminations is a portion of a circle, wherein the area of ​​the cross-section of the laminations is 75% of the area of ​​the circle. The sterilization indicator is 3M 1243A Class V chemical indicator.

Embodiment 2

[0081] Example 2: Lumen Process Challenge Test Tubes

[0082] The cavity-type process challenge test tube of Example 2 was prepared as in Example 1, except that there were 16 laminations in total, the distance between the laminations was 2 mm, and the length of the cavity for placing the vapor damping structure was 70 mm.

Embodiment 3

[0083] Example 3: Lumen Process Challenge Test Tubes

[0084] The cavity-type process challenge test tube of Example 3 was prepared as in Example 1, except that the cross-sectional area of ​​the laminations was 90% of the circular area.

Abstract

The invention provides a sterilization process challenge test tube. The sterilization process challenge test tube comprises a tube body, a steam damping structure, an optional porous material and a sterilization indicator, wherein one end of the tube body is provided with an opening and the tube body is composed of a transparent chamber for placing the sterilization indicator, a chamber for placing the optional porous material and a chamber for placing the steam damping structure; and in the sterilization process, steam sequentially passes through the opening and the steam damping structure and finally arrives at the sterilization indicator, wherein the optional porous material can be placed between the steam damping structure and the opening or the steam damping structure and the sterilization indicator.

Description

technical field [0001] The present invention relates to a device for verifying the efficacy of sterilization, and more particularly, to a challenge test device that can be used in an autoclave sterilization process. Background technique [0002] Many medical devices require sterilization before use. Due to the advantages of high efficiency, low cost, safety and environmental protection, steam is widely used in the sterilization process of hospital medical equipment. Specifically, the medical equipment that needs to be sterilized is placed in the cavity of the steam sterilizer, the air in the cavity of the steam sterilizer is removed by vacuuming and steam injection, and then high-pressure saturated steam is injected to achieve effective sterilization of the medical equipment. [0003] Some medical devices that need to be sterilized have characteristics similar to porous materials, such as dressing-type packages containing surgical gowns. Such medical devices that need to be...
