Abstract

A feeding fluid warming system broadly includes a liner bag and an ultraviolet light warming device. The liner bag includes an inner bag that receives feeding fluid therein and an outer bag that holds warming fluid therein. The warming device includes a container, an ultraviolet light source, a temperature sensor, and a controller. The container receives the liner bag therein and the ultraviolet light source heats the warming fluid, which in turn heats the feeding fluid to temperatures within a thermal neutral zone so as to effectively and consistently maintains the fluids at these temperatures in addition to sterilizing the warming fluid.

Claims

1. A feeding fluid warming system comprising:

a removable liner bag comprising;

an outer bag having an ultraviolet light permeable outer wall defining an outer chamber for holding a warming fluid; and

an inner bag at least partially contained within the outer bag, the inner bag having an ultraviolet light unpermeable outer wall defining an inner chamber for receiving a feeding fluid; and

a warming device comprising;

a container including a sidewall and a floor cooperatively defining an interior chamber for receiving the removable liner bag therein; and

an ultraviolet light source configured to emit ultraviolet light into the outer bag for sterilizing the warming fluid and for heating the warming fluid to warm the feeding fluid in the inner bag.

2. The feeding fluid warming system of claim 1, wherein the ultraviolet light source is a lamp.

3. The feeding fluid warming system of claim 1, wherein the ultraviolet light source comprises a plurality of ultraviolet C-band light emitting diodes.

4. The feeding fluid warming system of claim 1, wherein the ultraviolet light source comprises at least one vacuum ultraviolet light.

5. The feeding fluid warming system of claim 1, wherein the ultraviolet light source is embedded in the floor of the container.

6. The feeding fluid warming system of claim 1, wherein the ultraviolet light source comprises a plurality of lights arranged in a ring around the floor of the container for efficiently emitting ultraviolet light into the outer bag.

7. The feeding fluid warming system of claim 1, wherein the ultraviolet light source is embedded in the sidewall of the container.

8. The feeding fluid warming system of claim 7, wherein the sidewall includes a transparent window facing outward from the container for allowing a user to easily ascertain whether the ultraviolet light source is activated.

9. The feeding fluid warming system of claim 1, wherein the warming device further comprises a lid housing the ultraviolet light source.

10. The feeding fluid warming system of claim 1, wherein the outer bag includes an anti-microbial coating configured to inhibit the growth of bacteria and other organisms in the outer bag.

11. The feeding fluid warming system of claim 1, wherein the inner bag includes an anti-microbial coating configured to inhibit the growth of bacteria and other organisms in the inner bag.

12. The feeding fluid warming system of claim 1, wherein the warming device further comprises a controller configured to turn the ultraviolet light source off after a predetermined time interval for effectively sterilizing the warming fluid.

13. The feeding fluid warming system of claim 1, wherein the warming device further comprises a temperature sensor configured to sense a temperature of the warming fluid and a controller connected to the temperature sensor and configured to turn on the ultraviolet light source to increase the temperature of the feeding fluid to at least 90 degrees Fahrenheit and to alter the output of the ultraviolet light source to maintain the temperature of the feeding fluid between 90 degrees Fahrenheit and 100 degrees Fahrenheit.

14. The feeding fluid warming system of claim 13, wherein the warming device further comprises an indicator, the controller being further configured to activate the indicator when the temperature of the feeding fluid reaches 90 degrees.

15. The feeding fluid warming system of claim 1, wherein the warming device further comprises a vibrating mechanism configured to mix the warming fluid to ensure that the warming fluid is effectively sterilized.

16. The feeding fluid warming system of claim 15, wherein the vibrating mechanism is embedded in the floor of the container.

17. The feeding fluid warming system of claim 15, wherein the vibrating mechanism is embedded in the sidewall of the container.

18. The feeding fluid warming system of claim 1, wherein the liner bag further comprises a number of designated areas for marking identification information of the feeding fluid on the liner bag.

19. A feeding fluid warming system comprising:

a removable liner bag comprising;

an outer bag having an ultraviolet light permeable outer wall defining an outer chamber for holding a warming fluid; and

an inner bag at least partially contained within the outer bag and having an ultraviolet light unpermeable outer wall defining an inner chamber for receiving a feeding fluid; and

a warming device comprising;

a container including a sidewall and a floor cooperatively defining an interior chamber for receiving the liner bag therein;

a plurality of ultraviolet light emitting diodes embedded in the container, the ultraviolet light emitting diodes being configured to emit ultraviolet light into the outer bag for sterilizing the warming fluid and for heating the warming fluid to warm the feeding fluid in the inner bag;

a vibrating mechanism being configured to mix the warming fluid to ensure that the warming fluid is sterilized;

a temperature sensor for sensing a temperature of the warming fluid;

an indicator; and

a controller connected to the temperature sensor and the indicator, the controller being configured to;

turn on the ultraviolet light source to increase the temperature of the feeding fluid to at least 90 degrees Fahrenheit;

activate the indicator when the temperature of the feeding fluid has risen to at least 90 degrees Fahrenheit; and

alter the output of the ultraviolet light source to maintain the temperature of the feeding fluid between 90 degrees Fahrenheit and 100 degrees Fahrenheit.
