SpecialsNeedle Tip Pressure Transducers

Robust metal sensing diaphragms within a polished surgical steel needle

Excellent frequency response and compatible with a wide range of monitors.

The sensors are side mounted and the tip can be sharpened or domed.

They have been used in a variety of applications, both in experimental equipment and in clinical use for physiological measurements such as compartment pressure and intradiscal pressure. They have excellent frequency response and are compatible with a wide range of monitors.

Sterilisation is by means of cold aqueous solutions of detergicide (e.g. Cidex) or by ethylene oxide gas. Do not use sodium hypochlorite solution.
