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.

In the technical aspects of intracranial catheter tip transducers there are some technical properties that are of great importance. Such as, a titanium sensor housing, a "zero drift," which is equal to less than one mmHg in twenty four hours, rending it nearly motionless. As well, aspects such as a catheter that is 50 mm of silicone rubber with 2.4mm Ø.

Temperature coefficient of sensitivity in the range of < 0.05%FS/C°, as well as maximum balloon inflation and other factors will allow for a transducer tip that will aid in the maximum vigilance in monitoring, not to mention contributing to the life saving measures, of a patient who may have suffered an otherwise life threatening head trauma.

ICP Measurement Devices For Medical Use

There are several different types of ICP measurement devices in use today. These can be placed in various locations including the epidural, subdural, subarachnoid, parenchyma, or ventricular areas of the brain. The epidural method uses an intracranial catheter tip pressure transducer. Advantages of the epidural ICT include ease of placement, fewer incidences of hemorrhage, and a lower risk of infection since the dura does not need to be opened. This system is not dependent on a fluid column and it does not depend on an external transducer. This is a major advantage since it allows movement of the patient with the ICT in place.

In various medical devices like spirometers, respirators, sleep diagnostic equipment, and oxygen conservers, the differential pressure sensors perform the function of controlling the patients' breathing. As the respiratory flow carries significant amount humidity and is also generally warmer than the environment, this can be a reason for condensation to occur inside the device. The water droplets might condense on the tubing walls of the transducer thus leading to incorrect transducer output signal as well as a loss of the transducer collaboration. In worst circumstances, the flow channels might be blocked completely thus leading to a total failure of the transducer.
