Regulation of arterial blood pressure by means of drug infusion

Advance fuzzy-logic based closed-loop control

This application is an embedded control system for infused drug delivery.
The system comprises an infusion pump, a vital signs monitor and a controller which controls the drug delivery. All three pieces of equipment communicate with each other.
The system maintains arterial blood pressure within a narrow gap of pre-established values, lowering it in the cases that it is too high (hypertension) or avoiding sudden picks in surveillance mode.
This system captures the arterial blood pressure signal, evaluates it, and according to the measurement, updates every 20 seconds the dosage value in order to maintain the blood pressure closed to the target gap.
Areas of use are:
Clinical:

Treatment of hypertensive emergencies

Treatment of Acute cardiac failure refractary to conventional procedures

Miocardial Infarction with cardiac failure
Surgical :

Paroxistic hypertension during surgical intervention

Controlled hypotension

Medicaldevices communications in critical care wards

VITAL is a newly formulated CEN pre-norm (CEN/TC251/PT21 ) which is a high level protocol for the exchange of data between pieces of patient connected medical equipment. It is currently approved by TC251 expecting formal approval of ENV status before December 1998. VITAL works in conjunction with the new IEEE 1073 standards for bedside device.

RGB Medical Devices participates actively in the CEN and IEEE normalization groups.
RGB has been a major partner in a pan-european project called AORTICS, as an effort sponsored by the European commission . This project is providing implementation feedback to norms developers of the CEN TC251. A later EC approved project called "VITAL" will become the first real application for the norm.

The objective of VITAL is to prove that RGB�s medical monitor as well as an infusion pump can exchange information using VITAL international open norm, and that this scheme can be used as a basis for a wider application using different medical devices from different manufacturers.
