Portable single patient use carbon dioxide detector
First Claim
1. A carbon dioxide (CO2) detector for use with a cardiopulmonary resuscitator (CPR) device, the CO2 detector comprising:
- a top housing containing an inhale/exhale port connected to a CPR device, the top housing having a bore for receipt of a support for a clear plastic disc overlaying a chemically treated calorimetric indicator paper;
the indicator paper being partially covered with a backing paper prior to use, the backing paper protruding through a slot in the support and being removed by pulling on the protruding backing paper to fully expose the indicator paper;
a sealing ring juxtaposed to a bottom outer surface of the disc to seal the slot after removal of the backing paper; and
a bottom housing attached to the top housing, the bottom housing having a port for connection by a tube to a patient'"'"'s trachea.

Abstract
The CO2 detector has a bottom housing attached to a top housing. The bottom housing contains a rotatable port engageable to an intubation tube and multiple parallel integral filter support ridges on a top surface of a floor. A filter pad overlies the integral filter support ridges and a baffle overlies the filter pad. The baffle has multiple parallel filter support ridges on a bottom surface cooperating with the filter support ridges integral with the bottom housing to maintain the filter pad in position. The baffle has an air flow guide on a top surface and air passages. The top housing has a port connected to a CPR bag and a clear plastic disc overlying a CO2 calorimetric indicator paper. The colorimetric indicator paper is shown through a clear plastic cover after removing backing on the indicator paper through a sealable slot.

6. A carbon dioxide (CO2) detector for use with a cardio-pulmonary resuscitator (CPR) device, the CO2 indicator comprising:
-
a bottom housing containing an air flow port engageable to an intubation tube, the port descending from a floor of the bottom housing with a wall ascending from an outer edge of the floor, means for supporting an air filter on a top surface of the floor, an air filter mounted over the floor and a baffle mounted over the air filter;
a top housing attached to an upper edge of the ascending wall, the top housing having an air flow port ascending from a top surface, the air flow port engageable to a CPR bag, a clear plastic disc mounted on a support engaging a bore in the top housing, the support containing a slot below the disc for receipt of protruding backing paper so that color changes on a calorimetric indicator paper covered by the backing paper can be viewed through the clear plastic disc after the backing paper is removed from the slot. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A carbon dioxide (CO2) detector for use with a cardiopulmonary resuscitator (CPR) device, the CO2 detector comprising:
-
a top housing containing an inhale/exhale port connected to a CPR device, the top housing having a bore containing locking slots on an inner circumference, multiple legs descending from a support integral with a transparent disc, the multiple legs engaging and attaching to the locking slots to support the transparent disc on the top housing;
a slot below the disc in the support for receipt of a protruding backing paper, the pulling of the backing paper out of the slot causing an exposure of a calorimetric indicator paper;
a sealing ring juxtaposed to a bottom outer surface of the disc to seal the slot after removal of the backing paper; and
a bottom housing attached to the top housing for receipt of a filter and a port extending from the bottom housing for connection to a patient'"'"'s intubation tube. - View Dependent Claims (14, 15)
