Objective:To explore disinfection method for internal canula in . tracheotomy. 目的:总结气管切开内套管的消毒效果。
With certain shapes of nozzle or canula, elongated caps are made to cover both canula and threaded portion, and seal the canula at its top. 根据管口和导管的不同形状，可以制造细长的管盖以覆盖导管和螺纹部分，并在顶部封住导管。

Canula, and orifice features may be varied to suit particular requirements, provided these are within the practicabilities of the impact extrusion process on a mass-production basis. 管口;导管和孔口的形态可以根据不同的需要而有所变化;但是前提是它必须能够承受大规模生产过程中的冲挤压力.
