Background

In various industries relating to aseptic technology, such as medical care, health quarantine, pharmacy, etc., products, packaging materials, etc., are often required to be sterilized by ethylene oxide or other sterilization means. The sterilization effect needs to be detected in the sterilization process to ensure the sterilization effect. The common detection method is to place the biological indicator bacterial sheet at a position (detection position) where the product is difficult to sterilize, and detect whether the microorganisms on the biological indicator bacterial sheet meet the requirement of sterility level after the sterilization process is finished.

For tubular products (e.g., coiled tubing, straight tubing, bent tubular products, etc.), the location within the tubular product that is more difficult to sterilize is typically a location that is further from the orifice, and therefore, the biological indicator pellet needs to be placed within the tubular product at a location that is further from the orifice.

In the related art, one end of a mushroom piece is tied to the front end of a hypotube by using an adhesive tape, then the mushroom piece is rolled outside the hypotube, and then the mushroom piece is plugged into a position far away from a pipe orifice in a tubular product through the hypotube.

However, in the process of inserting the bacterial pellet into the tubular product through the hypotube, the friction force between the bacterial pellet and the inner wall of the tubular product may cause the bacterial pellet to separate from the hypotube, so that the bacterial pellet may not enter the detection part smoothly, thereby affecting the detection effect.

The cross-sectional shape of the receiving member 10 may also be any other regular or irregular shape, such as a square, trapezoid or asymmetrical pattern. The present application does not limit the specific shape of the receiving member 10.

It will be appreciated that the cross-sectional shape of the receiving member 10 may correspond to the cross-sectional shape of the tubular product 50, for example, if the tubular product 50 is circular in cross-section, then the receiving member 10 is circular in cross-section, which further facilitates the insertion of the receiving member 10 into the tubular product 50.

The conveying strip 20 may be any elongated structure capable of extending into the tubular product 50, for example, the conveying strip 20 may be an elongated rod-shaped structure, an elongated tubular structure, or the like, and the material of the conveying strip 20 may be metal or nonmetal.
