Sidestream gas sampling system with detachable sample cell
First Claim
1. A sample cell for use in sidestream respiratory gas monitoring, comprising:
- a sample cell body;
an interconnection element associated with the sample cell body and configured to cooperate with a corresponding feature of a sidestream gas measurement assembly that is configured to at least partially receive the sample cell, wherein the interconnection element is adapted to maintain the sample cell body in an engaged relation with the sidestream gas measurement assembly;
a sample chamber defined in the sample cell body for receiving a respiratory sample from a patient; and
a first window defined in a first wall of the sample cell body and forming at least a portion of a boundary of the sample chamber, wherein the first window facilitates analysis of an amount of a gas or vaporized material disposed in the sample chamber responsive to the sample cell and the sidestream gas measurement assembly being placed in an assembled relationship.

Abstract
A sidestream sampling system includes a sidestream gas measurement assembly and a sample cell configured to be assembled therewith. The sidestream gas measurement assembly includes a receptacle for removably receiving at least a portion of the sample cell. The sample cell is coupled to a sampling tube that is configured to communicate with an airway of an individual. When the sample cell is assembled with the sidestream gas measurement assembly, a window of the sample cell is oriented toward a corresponding source and/or detector of the sidestream gas measurement assembly to facilitate monitoring of an amount of at least one gas or vaporized material in an individual'"'"'s respiration.

12. A sidestream gas sampling system, comprising:
-
(1) a sidestream gas measurement assembly, including, (a) a housing, (b) a radiation source disposed in the housing, (c) a radiation detector also disposed in the housing, and (d) a receptacle associated with the housing; and
(2) a sample cell, including;
(a) a sample cell body, (b) a sample chamber defined in the sample cell body for receiving a respiratory sample from a patient, and (c) a first window defined in a first wall of the body and forming at least a portion of a boundary of the sample chamber, wherein the first window is disposed at a location on the sample cell body such that the first window is in optical communication with the radiation source, the radiation detector, or both, responsive to the sample cell be disposed in the receptacle, and wherein the window is substantially transparent to at least one wavelength of radiation to be used in determining an amount of a gas or vaporized material disposed in the sample chamber. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method of sidestream respiratory analysis, comprising:
-
placing a sampling tube in fluid communication with an airway of a patient, wherein the sampling tube is in fluid communication with a sample cell;
attaching the sample cell with a sidestream gas measurement assembly configured to analyze at least one parameter of respiration of such a patient; and
analyzing the at least one parameter using the sidestream gas measurement assembly. - View Dependent Claims (21, 22, 23, 24, 25, 26)
