Embodiment approach 1

[0059] Such as Figure 1 to Figure 7 As shown, the tube wall of the outer tube is provided with a tube wall notch 305, and the tube wall notch 305 penetrates from the outer surface 306 of the tube wall of the outer tube to the inner surface 307 of the tube wall of the outer tube, and the tube wall notch 305 is located at the upper end of the outer tube;

[0060] The cap cavity 405 is in the shape of a stepped hole and includes a cap small-diameter section 406 and a cap large-diameter section 407 connected successively from the lower end of the side wall 403 to the upper end of the side wall 403. The diameter of the large-diameter section 407 of the cap is It is larger than the diameter of the small diameter section 406 of the cap and has a cap step surface 408 at the junction of the large diameter section 407 of the cap and the small diameter section 706 of the cap;

[0061] The restriction structure includes an outer tube elastic hook 308 disposed in the notch 305 of the tub...

Abstract

The invention relates to a biological indicator for medical apparatus and instrument sterilization, in particular to a biological indicator ampoule puncturing mechanism. The puncturing mechanism comprises a metal thimble. The puncturing mechanism further comprises a spring, an upper layer filter screen and a lower layer filter screen. The metal thimble is fixed to the lower layer filter screen. The spring is arranged between the upper layer filter screen and the lower layer filter screen. The upper end of the spring abuts against the upper layer filter screen. The lower end of the spring abutsagainst the lower layer filter screen. The upper layer filter screen is provided with a thimble through hole for the metal thimble to penetrate through. According to the biological indicator ampoulepuncturing mechanism, because the upper layer filter screen and the spring are arranged to carry an ampoule above the metal thimble, the ampoule can be separated from the metal thimble for some distance, the risk that the ampoule is punctured by accident is reduced, and the reliability of an indicator is improved.

Description

technical field [0001] The invention relates to a biological indicator for sterilization of medical equipment, in particular to an ampoule piercing mechanism of the biological indicator. Background technique [0002] Chinese Invention Patent Application Publication Specification CN107823683A discloses a biological indicator with variable resistance, which assists the rupture of the ampoule by setting the rupture characteristic structure of the pointed object (ie, the piercing mechanism). However, the ampoule is supported on a pointed object, and it is prone to accidental rupture when it is shaken up and down during transportation and storage, making the indicator unusable and poor in reliability. Contents of the invention [0003] The object of the present invention is to provide an ampoule piercing mechanism of a biological indicator that can improve reliability, including a metal thimble, and the piercing mechanism also includes a spring, an upper filter screen and a low...
