Abstract
Abstract A respiration monitoring device for an infant patient includes three thermistors which are arranged so that one thermistor underlies each nostril and one thermistor overlies the patient's mouth. The thermistors are mounted on a thin flexible support member having an adhesive back so that the same can be temporarily secured to the patient's nose. The support member includes an upper portion which overlies the bridge of the nose and a lower portion which overlies the nostrils. The lower portion has a pair of openings therein and two of the thermistors are arranged in these openings. Each thermistor is enclosed in a fabric mesh material to prevent inhalation of fragments in the event of breakage. The support member may also carry a CO 2 sensor, an oxygen saturation sensor and/or a pulse rate sensor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
A respiration monitoring device comprising: a substantially thin, flexible support member having an outer surface and an inner surface; an adhesive carried by said inner surface, said adhesive being capable of temporarily but firmly securing said support member to a patient's skin; said support member having an upper portion which is adapted to overlie the bridge of a patient's nose when the same is in place and a lower portion which is adapted to overlie the patient's nostrils; a pair of spaced openings in the lower portion of said support member, said openings being adapted to be in substantial alignment with the patient's nostrils when said device is in place; a pair of thermistors carried by said support member, each thermistor being located in a different one of said openings whereby, when said device is in place on a patient's nose, said thermistors are substantially aligned beneath the patient's nostrils and, each of said thermistors being separately enclosed in a fabric mesh material to prevent pieces of the thermistor from being inhaled in the event of breakage of the same.
Claim 2
Dependent Claim
180 words
A respiration monitoring device comprising: a substantially thin, flexible support member having an outer surface and an inner surface; an adhesive carried by said inner surface, said adhesive being capable of temporarily but firmly securing said support member to a patient's skin; said support member having an upper portion which is adapted to overlie the bridge of a patient's nose when the same is in place and a lower portion which is adapted to overlie the patient's nostrils; a pair of spaced openings in the lower portion of said support member, said openings being adapted to be in substantial alignment with the patient's nostrils when said device is in place; a pair of thermistors carried by said support member, each thermistor being located in a different one of said openings whereby, when said device is in place on a patient's nose, said thermistors are substantially aligned beneath the patient's nostrils and, each of said thermistors being separately enclosed in a fabric mesh material to prevent pieces of the thermistor from being inhaled in the event of breakage of the same.
Claim 3
Dependent Claim
41 words
The invention as claimed in claim 1 further including a third thermistor carried by said support member and extending downwardly therefrom, said third thermistor being adapted to overlie a patient's mouth when said device is in place on the patient's nose.
Claim 4
Dependent Claim
29 words
The invention as claimed in claim 1 wherein said support member further carries a carbon dioxide sensing tube, an end of said tube lying within one of said openings.
Claim 5
Dependent Claim
18 words
The invention as claimed in claim 1 further including an oxygen saturation sensor carried by said support member.
Claim 6
Dependent Claim
18 words
The invention as claimed in claim 1 further including a pulse rate sensor carried by said support member.
