Vishay Precision Group has declared that their VPG Transducers section is offering the entire series of force sensing devices for infusion pump fabricators, satisfying mounting, force calibration capacity, connectivity, and precision constraints.
The infusion pumps are utilized for medical applications and need high-performance, precise force sensors with recurrent and secure functionality. In order to satisfy this demand, the force sensors from VPG Transducers employ secure strain gage technology and occupies absolutely in the infusion pump architecture to lessen space requisites. VPG Transducers’ sister concern, Micro-Measurements has developed the strain gage, keeping close control of the complete manufacturing process, providing high product security and standard.
Mostly two VPG sensors are used in each infusion pump, communicating with the patient line at various areas to calculate minute deviations in the structure of the lines. One sensor calculates the elevating pressure before the pump in the line and tracks even a syringe, vacant bag, a crimp or interrupted line. The second sensor validates the downward pressure in the line and identifies crimped lines and vein blocks. The sensors also track the occurrence of air bubbles. The calibrated minute-deviations are transferred to the suitable pressure change using infusion pump electronics.
