A testing apparatus employs an interface module removably attached to a filter testing device. The interface module includes a first flowpath communicating with an outlet of the testing device and a housing of the filter device, a first valve disposed in the first flowpath, a second flowpath communicating with the housing of the filter device and an exhaust, a second valve disposed in the second flowpath, and an enclosure enclosing the first flowpath, the first valve, the second flowpath, and the second valve. The interface module is cleanable and/or sterilizable, and replaceable. A filter integrity testing method uses an interface module to prevent contamination of the testing device and cross-contamination of different filter devices and avoid liquid ingress into the testing device.

Interface module for filter integrity testing

A method and system for measuring the dimensions of the palpable surface of the prostate in the physician's office and calculating prostate volume, rate of growth and changes in rate of growth. A membrane with a grid pattern is located proximate the prostate. A physician moves a measurement system, formed at the end of the index finger and located in a glove, between opposite margins of the prostate. The measurement system counts the grid elements between the margins that translate into a quantitative measurement of size of the palpable surface of the prostate.
