Ano-Rectal (Lower GI)Catheter Tip Transducers

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

Excellent frequency response and are 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.

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. We can make special units with lumens, balloon ties, EMG electrodes and multiple sensors at one location. For instance, we have made multiple sensor catheters approximately 7mm Ø with a 6F 2mm Ø PTFE tube with balloon tie able to slide within the central lumen.
