Abstract

The disclosure provides an apparatus, system and method of providing a flexible heater on at least one conformable substrate of a medical fluid bag. The disclosed embodiments may include providing a matched function ink set, printed onto at least one substantially planar face of the at least one substrate to form at least: at least one conductive layer capable of receiving current flow from at least one power source; at least one resistive layer electrically associated with the at least one conductive layer and comprising a plurality of heating elements capable of generating heat upon receipt of the current flow; and at least one dielectric layer capable of at least partially insulating the at least one resistive layer.

First claim

What is claimed is:

1. A flexible heater formed on at least one conformable substrate of a medical fluid bag, comprising:
a matched function ink set, printed onto at least one substantially planar face of the at least one substrate to form at least:
at least one conductive layer capable of receiving current flow from at least one power source, having a cartridge physically and electrically associated with the at least one conductive layer;
at least one resistive layer electrically associated with the at least one conductive layer and comprising a plurality of heating elements capable of generating heat upon receipt of the current flow; and
at least one dielectric layer capable of at least partially insulating the at least one resistive layer;
wherein the matched ink set is matched to preclude detrimental interactions between the printed inks of each of the at least one conductive, resistive and dielectric layers, and to preclude detrimental interactions with the at least one conformable substrate.

2. The flexible heater of claim 1 , wherein the substrate comprises an inorganic substrate.

3. The flexible heater of claim 1 , wherein the substrate comprises one of PET, flexible PVC, and polyether polyurethane.

4. The flexible heater of claim 3 , wherein the substrate comprises a thickness in the range of 6 mm and 10 mm.

5. The flexible heater of claim 1 , wherein the detrimental interactions occur during at least one of deposition and curing of the printed inks.

6. The flexible heater of claim 1 , wherein the printed inks in the matched ink set comprise at least one positive temperature coefficient ink.

7. The flexible heater of claim 1 , wherein the medical fluid bag comprises a blood bag.

8. The flexible heater of claim 1 , further comprising two of the at least one conformable substrates on opposing faces of the medical fluid bag, each having thereon a one of the flexible heater.

9. The flexible heater of claim 1 , wherein the two flexible heaters are electrically connected by at least one of a trace around, a via, and a pass through.

10. The flexible heater of claim 1 , further comprising a control circuit connectively associated with the cartridge.

11. The flexible heater of claim 10 , wherein the control circuit controls an amount of heat delivered by the heating elements.

12. The flexible heater of claim 11 , wherein the control system comprises a wireless receiver.

13. The flexible heater of claim 12 , wherein the wireless receiver comprises at least one of a Bluetooth, WiFi, NFC, cellular and RF receiver.

14. The flexible heater of claim 11 , wherein a wirelessly linked remote portion of the control system comprises a mobile device app.

15. The flexible heater of claim 10 , further comprising at least one power source connectively associated with the control circuit.

16. The flexible heater of claim 15 , wherein the power source comprises one of a rechargeable battery and a power outlet plug.

17. The flexible heater of claim 1 , wherein the physical and electrical connection comprise removable connections.

18. The flexible heater of claim 17 , wherein the removable physical connections comprise at least one of clips, snaps, latches and Velcro.

19. The flexible heater of claim 1 , wherein the dielectric layer insulates ones of the plurality of heating elements from shorting onto one another due to the conformability of the conformable substrate.

20. The flexible heater of claim 1 , wherein the dielectric layer insulates heat produced by the heating elements to avoid localized overheating.
