Pressure Measurement Equipment For Urology

The general definition of a catheter, as medical equipment, can be given as a flexible instrument, featured with a tubular shape, which is inserted into an opening of the body to take out or introduce liquid.

A catheter tip pressure transducer for identifying the pressure in different parts of a human or animal body correctly through body openings or surgical incisions. A catheter pressure transducer can also be introduced to the body through other catheters which are already placed in the body.

What is Catheter Tip Pressure Transducer Used For?

This medical instrument securely contains a pressure sensor predisposed within the last part of a catheter. This pressure sensor also includes a pressure sensitive diaphragm whereon strain estimates are developed through the diffusion method.

This pressure sensor is built up on an insulated sustaining component which is however not secured firmly thereto. A shielding component prepared from silicone rubber fills the unfilled segment of the catheter thus protecting the pressure sensor as well as the ambient body tissue. The pressure sensor is helpful in measuring the pressure accurately without being swayed by the thermal stresses occurring in the sustaining component.

Pressure Measurement Equipment For Urology

The urology tip pressure catheters being used at present include pressure sensors that take the form of photoelectric-type sensors, capacitive type sensors, or resistive type sensors. The photoelectric type transducers involve light fibers passing the pressure signals from the sensor all the way through the length of the catheter to a measurement device. In the same way, the capacitive type and the resistive type sensors involve the use of insulated electrical wires to transfer pressure signals from the sensor through the catheter. All the procedures involved in the formation of a urology catheter tip pressure transducer are delicate and protracted. Besides, they also require skill and patience to get done successfully.

Since it is generally difficult to apply a completely uniform coating of RTV, as is requisite for consistency in pressure management, the outcomes of the installation of a fresh sensor are not always what is needed and the RTV might have to be customized or the sensor reinstated to congregate the stability chuck important for good performance of a urology catheter tip pressure transducer.

Installation Process

Adding more to the point, these installation processes are generally performed directly within the catheter tip pressure transducer thus making the work extremely delicate, expensive, and time consuming.

Also, these urology catheter tip pressure transducers are, generally, available either for single use in the form of sterile disposable items, or even for multiple uses that involve cleaning, sterilizing and then using it for innumerable times. Since the catheter tip pressure transducers feature a very small diameter, i.e. 0.5 turn to 3mm, when introduced into small vessels like the urinary tract, the pressure sensors being delicate, can get damaged during the use. Thus, it is essential to have a device that provides itself to be easily installed during the manufacture process of the catheter tip transducer and too be replaced easily as and when required.

Essential Features of Catheter Tip Pressure Transducers

Besides, it is also essential for a catheter tip transducer to include a pressure sensor that mitigates the problems in addition to reducing the related costs of the conventional manufacturing procedures.
