A complete Uson ostomy bag test system, whose quality is now assured to full FDA requirements, has been purchased by medical products manufacturer Salts Healthcare of Birmingham.

A complete Uson ostomy bag test system, whose quality is now assured to full FDA requirements, has been purchased by medical products manufacturer Salts Healthcare of Birmingham.

The semi-automatic system installed provides 100% product integrity checking for leaks on the joining of the different materials together during bag manufacture.

Its custom sealing heads can be quickly interchanged with different couplings for the full product range and a dry air pressure decay technique is used to accurately determine a precise leak rate.

Salt's Neil Wiltshire remarked "We have a commitment to producing high quality products and as such the test rig we purchased from Uson is ideal.

The machine was modified to our requirements and has proved a great success.

" Pass and Fail limits can be set at different test stages so that both fine and gross leaks are detected and measured, while bag flexing is overcome by upper and lower restriction plates coated with a porous material ensuring that the smallest leaks are not masked.

Test data can be logged to the tester or sent to external devices such as a PC, PLC or datalogger.

A unique Uson compensation/calibration with self-teach feature minimises cycle times, and test programs can include a vacuum exhaust to flatten the bag for ease of packing.
