Abstract

The breathing device (10) has an inner section (14) having an inlet (32) defined therein. The section (14) has a motor (20), a fan (24) and a processor (22) disposed therein and the section (14) has an outlet (34) defined therein. The outlet (34) is in fluid communication with the inlet (32) so that pre-heated air is being be propelled by the fan (24) to pass from the inlet (32) across the processor (22), over the motor (20) and out through the outlet (34). An outer section (16) has a container (26) attached thereto that has a channel (42) defined therein. The channel (42) has a water-absorbing material (44) disposed therein for increasing the humidity of the air passing therethrough. A tube (28) is connected to the outer section (16) for carrying air from the channel (42) to a mask (30) attached to one end of the tube (28).

Claims

1. A breathing device, comprising:

an inner section (14) having an inlet (32) defined therein, the section (14) having a fan (24) and a processor (22) disposed therein, the section (14) having an outlet (34) defined therein, the outlet (34) being in fluid communication with the inlet (32) so that air is being be propelled by the fan (24) to pass from the inlet (32) across a motor (20), the processor (22) and out through the outlet (34);

an outer section (16) attached to the inner section (14), the section (16) having a container (26) attached thereto, the container (26) having a channel (42) defined therein, the channel (42) having a water absorbing material (44) disposed therein; and

a tube (28) connected to the outer section (16) for carrying air from the channel (42) to a mask (30) attached to one end of the tube (28).

2. The breathing device according to claim 1 wherein the channel (42) is S-shaped.

3. The breathing device according to claim 1 wherein the container (26) has a lid (40), the lid (40) having an opening (38) defined therein for communicating with

4. The breathing device according to claim 1 wherein the inlet (32) has a filter (33) disposed therein.

5. The breathing device according to claim 1 wherein the breathing device (10) has a sensor (58) connected thereto.

6. The breathing device according to claim 1 wherein the processor (22) has a communication device (62) for wireless communication with a computer (64).

7. The breathing device according to claim 1 wherein the container (26) has a heating layer (54) disposed below the container (26) and above a bottom (56) of a housing (12).

8. The breathing device according to claim 1 wherein the material (44) are attached along side walls of the channel (42).
