PREMATURE INFANT SIDE-STREAM RESPIRATORY GAS MONITORING SENSOR
First Claim
1. A side-stream respiration monitoring sensor comprising:
- a body;
a flow path formed through the body for communicating a respiration gas through the body;
a restricting member extending from the body into the flow path;
a first port extending through the body proximate a first side of the restricting member;
a second port extending through the body proximate a second side of the restricting member; and
a sample port for acquiring a sample of the respiration gas extending through the body on a downstream side of the first and second ports relative to a patient.

Abstract
A side-stream respiration monitoring sensor includes a body having a first end, a second end, and a detecting section disposed between the respective ends. The detecting section includes a first port and a second port positioned on generally opposite sides of a restricting member. The restricting member extends into a flow path formed through the body such that a pressure differential is generated between the first port and the second port. A sampling port is positioned downstream relative to a patient from the first and the second port and configured to acquire a respiration sample. The sensor is constructed to monitor respiration performance of premature infants “preemies”, or the like.

9. A premature baby respiration monitoring sensor comprising:
-
a sensor for engaging a respiration flow of the premature baby; a passage formed through the sensor; a restriction extending into the passage; a first flow port and a second flow port extending through the sensor on generally opposite sides of the restriction; and an aspiration port extending through the sensor adjacent only one of the first flow portion and the second flow port. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of forming a respiration monitoring system comprising:
-
forming a body; forming a respiration flow passage through the body; forming a first passage through the body fluidly connected to the respiration flow passage; forming a second passage through the body fluidly connected to the respiration flow passage; forming a restriction positioned between the first passage and the second passage in the respiration flow passage; and forming a third passage through the body and remote from a patient side of each of the first passage, the second passage, and the restriction for acquiring a sample of gas passing through the respiration flow passage. - View Dependent Claims (18, 19, 20, 21)
