Abstract

The invention is a device that consists of an assemblage of shielded resistors and temperature monitoring sensors. The managing of these functions is effected by central control unit, which receives electricity and converts it to a 40 to 60 Volt band thus feeding the resistors and controlling the chosen temperature through sensors included in the device.

Claims

1. A device for heating and monitoring of parenteral fluids comprising:

(a) a container having heating and temperature monitoring systems of fluid in single and multiple container sets for parenteral fluids, said container storing bottles, or packages of intravenous solution by units in a heated pouch equipped with a sealing device and sealed conductor linked by an electric connector, and said container providing temperature monitoring of the intravenous solution while the intravenous solution is being administered to the patient through a needle directly from an exit tip of a catheter extending from said container to the patient and having a temperature sensor,

(b) a protracted thermal bag that covers said catheter for heating and maintaining the temperature of the intravenous solution from the container to the patient;

(c) a visualizing dripping cup and a regulator to allow control of the solution flow rate; and

(d) a central control unit electrically connected to said container and to at least one temperature sensor, which is arranged to regulate the power supplied to electrical resistors according to user data entered into said central control unit and signals received from the temperature sensor for heating said solution, which, in use, is fed into the patient through said needle.

2. The device according to claim 1 wherein said container provides a consistent heating of the heating pouch.

3. The device according to claim 1 wherein the dispensing of intravenous solutions is at a constant temperature of 36 degrees C., plus or minus 1 degree C.

4. The device according to claim 1 wherein said protracted thermal bag covering the catheter is equipped with electrical resistors electrically connected to and regulated by the central control unit, for the purpose of preventing heat losses along this catheter.

5. The device according to claim 1 wherein at least one temperature sensor is associated with a free end of the protracted thermal bag for monitoring the temperature of the intravenous solution at this point.
