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.
Urology Void Sensors
The urology void sensors are fully implantable wireless pressure sensors which are produced to examine bladder pressures in the vivo. This sensor system includes a small commercial pressure die connected through a catheter to amplifying devices, wireless transmitter, microcontroller, battery, and a personal digital assistant (PDA) or computer to obtain the wireless data. Moreover, these urology void sensors are completely implantable and also transmit pressure data once per second. This pressure detection range is 1.5 psi gauge with a resolution of 0.02 psi.
Ambulatory Recordings
The ability to use nanologgers with ambulatory patients is a tremendous advantage, especially for clinical trials that require the test subjects to engage in a variety of activities. By avoiding the need to keep patients stationary, these ambulatory recorders can contribute to the accuracy of the study. In addition, they can drastically reduce the inconvenience and discomfort some patients might otherwise suffer.
While of course catheters are in fact available in an abundant variety of specifications, it is also possible to manufacture them according to diameter, length, and location of the electrode. When necessary, the catheter might be specific to unitary or multiple lumen variations.
Medical Equipment Pressure Transducers
Medicine requires very precise measurements. Pressure readings must be accurate when delivering gases - like oxygen, nitrogen and carbon dioxide - to patients. The differential gas pressure transducer is used to monitor medical equipment to ensure that patients are receiving the proper treatment.
Surgical procedures demand extreme accuracy. If a vacuum is required for a surgical process, then a pressure transducer may be needed. The best pressure transducers can measure both positive and negative values.
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.
