The primary objective of the IV™flow is the maintenance of a constant hydrostatic pressure in the fluid container.
However, the IV™flow has been designed mainly to resolve three additional and specific issues currently experienced in the disposable infusion industry, namely:
safety issues; and
consistent accuracy throughout the entire administration process.
The IV™flow is a small valve-like device which is situated just beneath the fluid container (typically called a vaculiter) in the fluid path.
Its function is to maintain a constant hydrostatic pressure throughout the administration process using atmospheric pressure as the reference point. The result is a constant flow of fluid from the container and maintenance of this flow rate at all levels of the vaculiter, whether it is full, half-full or nearly empty.
Its second unique function is its built-in shut-down mechanism. This mechanism virtually eliminates the risk of a cryogenically-induced air embolism (air bubble in the fluid path), the back-flow of blood and clotting, the need to reprime and also the need to recalibrate the infusion device when the fluid container runs empty. These advantages represent enormous time and consumable saving for both the clinician responsible for the maintenance of the IV sets as well as the hospital administration.
The events described are a constant threat to the safety and comfort of the patient as it can have fatal consequences. In addition, there is the medical legal risk faced by management and the time required to manage these devices.
Nurses typically spend up to 17% of their effective time managing IV sets and it is not uncommon for them to have to care for up to 50 patients at once, each one with an IV set that needs to be checked constantly. Hospitals can also save on the wastage of fluids when the containers are nearly empty, since an empty container will no longer be a constant threat.
