Tubular medical instrument air tightness testing device and testing method thereof

Abstract

The invention discloses a tubular medical instrument air tightness testing device and a testing method thereof, and belongs to the technical field of medical instruments. The tubular medical instrument air tightness testing device comprises a detection barrel assembly; a vacuumizing assembly which is mounted at the bottom of the side surface of the detection barrel assembly; a top cover assembly which is mounted at the top of the detection barrel assembly; an air inflation assembly which is mounted on a top air inlet of the top cover assembly; and a bottom cover assembly which is mounted at the bottom of the detection barrel assembly. The detection barrel assembly comprises a barrel body, a barometer which is mounted at the top of the side surface of the barrel; and an exhaust connector which is installed at the bottom of the side face of the barrel, and an inner cavity of the exhaust connector is communicated with an inner cavity of the barrel. According to the present invention, the air tightness of the tubular medical instrument can be effectively tested, and the quality of the tubular medical instrument can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for testing the air tightness of tubular medical devices and a testing method thereof. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including required computer software. The effect is mainly obtained through physical methods, not through pharmacological, immunological or metabolic methods, or although these methods are involved, they only play an auxiliary role. The purpose is diagnosis, prevention, monitoring, treatment or mitigation of disease; diagnosis, monitoring, treatment, mitigation or functional compensation of injury; examination, replacement, regulation or support of physiological structures or physiological processes; life support or maintenance; pregnancy contro...
