A University of South Australia research team has developed a unique, low cost disposable solid-state catheter that can measure swallowing pressure without the infection risks posed by existing catheters.

The new catheter has many advantages over existing catheters, according to UniSA research fellow Dr Hung-Yao Hsu, who is developing the catheter with industry partner, the Women's and Children's Hospital (WCH).

"The new catheter uses solid-state sensors to measure the pressure of swallowing and eliminate the risk of fluid getting into the airway. These sensors are very responsive to pressure changes and give accurate, high resolution real-time readings. And while most catheters on the market only measure pressure, the new catheter is multifunctional, capable of recording a range of measurements," Dr Hsu said.

"In addition, it is estimated that the new catheter will be about ten times cheaper than current models, and is designed for single use only, eliminating the risks associated with reuse."

Researchers claim that the new catheter will have important outcomes for improved health and comfort of patients, as well as significant savings in the cost of health care, both nationally and internationally.
