ABSTRACT:
An apparatus for simultaneously detecting leaks in a plurality of flexible, collapsible bag-like devices is disclosed. The apparatus comprises a platen having a plurality of openings for receiving bag-like devices or contraceptive devices such as a female condom made of latex, polyurethane, or other polymer material. The apparatus has a first pressurizing device for pressuring the bag-like device in the platen with a medium such as air. A pressure sensor is used for detecting a failure to hold a selected pressure in each of the pressurized bag-like devices. The apparatus has an identification device for identifying bag-like devices exhibiting a failure to hold the selected pressure. An evacuation device for evacuating the bag-like device is used. The apparatus has a second pressurizing device for pressurizing the bag-like device with a leak detection medium and a detector for detecting any leak detection medium leaking from the bag-like device. A method for testing bag-like devices or contraceptive devices is, also, disclosed.
