Abstract
A gas delivery, evacuation and respiratory monitoring system comprising a face mask having a fresh gas inflow passage member, an exhaust-gas outflow passage member and a gas sampling outflow passage member is adapted to be coupled to a fresh gas source, an exhaust-gas scavenging system, and a carbon-dioxide monitoring device, also known as a capnograph, respectively. The face mask is characterized in part by a dome portion affixed to a continuous side wall portion which dome portion may be adapted for azimuth rotation thereon.
Claims13
A face mask for use in a gas delivery, evacuation and respiratory monitoring system wherein said system allows a user to deliver at least one gas and scavenge the exhausted gasses as well as monitor the exhausted gases in a safe and efficient manner, said face mask comprising:
- a face recipient portion adapted to fit over at least the nose and mouth area of a person's face, said face recipient portion being characterized by a continuous side wall portion and a dome portion supported by said continuous side wall portion, said dome portion forming a closed portion of said face mask defining a recess therein adapted to receive at least the nose portion of a person's face, and
- wherein said dome portion includes a first passage member for coupling to a carbon-dioxide monitoring device, and a second passage member for coupling to a source of fresh gas.
The method of using a gas delivery, evacuation and respiratory monitoring system on a patient for allowing the system to deliver at least one gas and scavenge the exhausted gasses as well as monitor the exhausted gases in a safe and efficient manner, comprising the following steps:
- (a) providing a face mask comprising a face recipient portion adapted to fit over at least the nose and mouth area of a patient's face, said face recipient portion being characterized by a continuous side wall portion and a dome portion supported by said continuous side wall portion, said dome portion forming a closed portion of said face mask defining a recess therein adapted to receive at least the nose portion of a patient's face, said dome portion including a first passage member for coupling to an exhaust-gas sampling tube attachable to a carbon-dioxide monitoring device, a second passage member for coupling to a source of fresh gas, and a third passage member for coupling to an exhaust-gas scavenger;
- (b) snugly fitting said face mask on said patient's face;
- (c) providing a fresh gas source, a carbon-dioxide monitor and an exhaust-gas scavenger;
- and
- (d) coupling said first passage member, said second passage member and said third passage member to said carbon-dioxide monitor, said fresh gas supply, and said exhaust-gas scavenger, respectively, whereby said system delivers at least one gas to said patient and scavenges the exhausted gasses as well as monitors the exhausted gases in a safe and efficient manner.
