Pressure transducers and catheters are used in evaluating either lower or upper urinary tract. These devices convert the changes in pressure into electrical pulses that are amplified and then recorded using special devices. Catheter tip pressure transducers are used for detecting pressure in different parts of the body safely and accurately.
Urology catheter tip pressure transducer helps in recording complex urologic problems in the pelvic floor, urethra and bladder. It is especially useful in recording direct urethral pressure.
Sensing Diaphragms of Urology Catheter Tip Pressure Transducers
The catheter tip pressure transducers have sensing diaphragms made of robust metal, which are mounted inside flexible and soft silicone rubber. They also incorporate directly deposited resistive strain gauges. The transducers have good frequency response, are ideal for all types of urological applications and compatible with different types of monitors.
Why Use Urology Catheter Tip Pressure Transducers?
Using urology catheter tip pressure transducer in urology applications will help to eliminate the complications associated with external transducers that are connected to fluid-filled lines.
Ho Do Catheter Tip Pressure Transducers Work?
The catheter tip pressure transducers make use of either semiconductor or fibre-optic materials that change resistance when pressure is exerted on them. They are ideal for measuring the pressure at the location of the catheter, which simplifies the processes of calibration and zeroing.
Pressure Sensing Technology For Urology
The catheter tip pressure transducers using semiconductors sense pressure as a result of the piezoresistive effect. They have silicon membranes having semiconductor diffused resistors, which are sidewall-mounted, whose resistances change with changes in pressure. The pressure-sensing element is mounted in the catheter wall, often along the tip.
What Can Urology Catheter Tip Pressure Transducers Measure?
Such a urology catheter tip pressure transducer can measure both mechanical and fluid forces exerted on its sensing surface. It has dynamic characteristics that make it more than capable of handling the required demands. Its drawback is that it measures pressure in one direction only, which may lead to artefact inaccuracy.
Accurate Pressure Measurement Readings Using Catheter Tip Pressure Transducers
The catheter tip pressure transducers using fibre-optic material have their pressure-sensing membranes oriented perpendicular to the direction of the longitudinal probe. Although the transducers provide accurate measurement of the surrounding fluid pressure, they have limitations in measuring mechanical forces.
The type of work will determine the best urology catheter tip pressure transducer. The transducers can be sterilised using cold detergicide aqueous solutions or ethylene oxide gas. However, sodium hypochlorite solutions should not be used.
