Oesophageal (Upper GI)Catheter Tip Transducers

Robust metal sensing diaphragms mounted within a soft flexible silicone rubber catheter

Excellent frequency response and simple to use for standard manometry as well as ambulatory recording.

Compatible with a wide range of monitors, which have been set for use with conventional transducers having a sensitivity of 5µV/V/mmHg.

Sterilisation is by means of cold aqueous solutions of detergicide (e.g. Cidex) or by ethylene oxide gas. Do not use sodium hypochlorite solution.

All the catheters can be supplied to order with centimetre markings or a soft tip extension.

Gaeltec Devices is able to supply variations in the sensor spacing on these standard items to suit the particular requirements of the customer usually at no extra cost. Over the years we have made a wide variety of devices using our proven technology. If you have a special need, ask us.
