Abstract

A controller and a plurality of concatenated heating modules in electrical communication with the controller. The controller controls the flow of current to the plurality of heating modules in response to temperature measurements from at least one of the plurality of heating modules. In one embodiment, each of the plurality of heating modules concatenated with another heating module is connected by Luer-Lok™ connectors. In another embodiment, the modular medical fluid heating system further includes an auxiliary heating unit in electrical communication with the controller and in physical juxtaposition with the plurality of heating modules. The invention also relates to a heating module for a modular medical fluid heating system including a fluid input port; a fluid output port; and serpentine tubing through which fluid passes from the fluid input port to the fluid output port. In one embodiment, the heating module can be concatenated with other heating modules.

Claims

1. A modular medical fluid heating system comprising:

a controller; and

a plurality of concatenated heating modules in electrical communication with the controller, each heating module comprising a conduit and a heating element along the conduit;

wherein the controller controls a flow of current to the plurality of heating modules in response to temperature measurements from at least one of the plurality of heating modules.

2. The modular medical fluid heating system of claim 1 wherein each of the plurality of heating modules connected to another heating module is connected by Luer-Lok™

connectors.

3. The system of claim 1 further comprising an auxiliary heating unit capable of being in electrical communication with the controller and in close physical juxtaposition with the plurality of heating modules.

4. The system of claim 1 further comprising a portable power supply.

5. The system of claim 4 wherein the portable power supply is selected from the group of a fuel cell, a standard battery, a lithium ion battery, a solar cell , a lead acid battery, a vehicle power supply and an AC source.

6. The system of claim 1 wherein the plurality of heating modules are arranged linearly.

7. The system of claim 1 wherein the plurality of heating modules are arranged in a three dimensional arrangement.

8. A heating module for a modular medical fluid heating system comprising:

a fluid input port;

a fluid output port;

a conduit through which fluid passes from the fluid input port to the fluid output port, the conduit having a heating element; and

wherein the heating module can be concatenated using the fluid input port and fluid output port with other heating modules to form a longer fluid path.

9. The heating module of claim 8 wherein the fluid input port and the fluid output port comprise Luer-Lok™

connectors.
