Pressure Testing Intra-aortic Balloon Catheters

Medical companies that design and manufacture IAB catheters need to test the pressure sensor, which is a key element of the catheter and in turn the entire IABP system. The pressure sensor usually needs to be tested as part of the complete assembly or tray, which is typically the package used to transit the IABP to the medical facility. In order to perform this test, the entire tray assembly ...

Medical Sensors for Implants and Catheters – NanoScale ...

Pressure Diaphragm for Your Medical Applications. Every pressure measurement in the body is based on the diaphragm (or membrane), for short or long-term intravascular, intracardiac or neurovascular blood pressure measurements. Its minimum size and material consistency mainly determine the actual benefit and application possibilities, as diagnostic implants or catheters in the ...

Pressure Sensor Applications: What Are They Used For ...

Industrial applications. Submersible pressure sensors can be used to measure liquid pressures (up to 30 PSI) with either a voltage or current (4-20mA) output in liquid tanks. By positioning these sensors at the bottom of a tank, you can get an accurate reading of the contents in order to alert workers or the process control system when levels in the tank fall below safe limits.

Mikro-Cath™ Pressure Catheter | Millar Clinical Products

The Mikro-Tip® sensor measures blood pressure, airway pressure, or compartment pressure at the source, providing a true representation of the pressure data and eliminating many of the common shortfalls of fluid-filled catheters, including signal variances from the patient position or timing delays. There is minimal noise and no air bubbles or motion artifacts to interfere with the signal.

Sensors for Thermo-Dilution Catheters | TE Connectivity

Using data from the temperature sensor in the tip of the catheter and the known starting temperature of the solution can determine the CO. However, due to the nature of these methods the CO result is intermittent. Other methods use the systolic portion of the arterial pressure and aortic impedance that offers a continuous display of CO. Whichever method is used, one driver remains constant ...

Choosing MEMS Pressure Sensors for Medical Device Applications

· MEMS pressure sensors have a long history in medical applications, and have been used in non-invasive medical equipment, such as respiratory gear and blood pressure cuffs, since the 1980s. More recently, MEMS pressure sensors have been used for invasive applications as well, including as catheter tip sensors, or as an implant reporting on blood pressure (systolic and …
