Abstract
Official abstract text for this publication.
An oxygen mask configured for CO2 sampling and oxygen delivery, the oxygen mask having an oxygen inlet, a nasal breath-sampling element and a breath sampling port configured to receive breath samples, sampled by the breath-sampling element, wherein the breath-sampling element is configured to reduce dilution of exhaled breath by the delivered oxygen.
First claim
Opening claim text (preview).
The invention claimed is: 1. An oxygen mask configured for CO 2 sampling and oxygen delivery, the oxygen mask comprising: an oxygen inlet, a nasal breath-sampling element configured to reduce dilution of exhaled breath by the delivered oxygen, wherein the nasal breath-sampling element comprises an inner sampling compartment, wherein the oxygen mask comprises an inner wall separating the oxygen mask into the inner sampling compartment and an outer oxygen delivery compartment and wherein the inner wall comprises a plurality of oxygen supply perforations through which oxygen can reach the inner sampling compartment; and a breath sampling port configured to receive breath samples, sampled by the breath sampling element. 2. The oxygen mask of claim 1 , wherein the nasal breath- sampling element is molded on, or otherwise attached to, an internal side of the oxygen mask. 3. The oxygen mask of claim 1 , further comprising an oral sampling element configured for sampling exhaled breath from a subject's mouth when in use. 4. The oxygen mask of claim 1 , wherein the nasal breath- sampling element comprises two nasal prongs fitted within the mask so as to be positioned within or below a subject's nostrils when in use. 5. The oxygen mask of claim 4 , wherein the two nasal prongs are connected to an adjustment handle, the adjustment handle located outside the oxygen mask, wherein movement of the adjustment handle enables adjusting a position of the two nasal prongs within the oxygen mask. 6. The oxygen mask of claim 1 , wherein the inner sampling compartment comprises two nasal prongs fitted within the inner sampling compartment so as to be positioned within or below a subject's nostrils, when in use. 7. The oxygen mask of claim 1 , further comprising a breath sampling tube attached to the breath sampling port.
