Abstract
A monitor-patient connector used with a lung inflection point monitor for measuring critical opening pressure, over distention pressure, and critical closing of lungs. The monitored-patient connector apparatus is used in conjunction with a lung inflection point monitor, and may be connected to a ventilator breathing circuit. The connector includes a proximal opening for connecting to a patient; a distal end that may be connected to the ventilator breathing circuit, a gas injection port for connecting the connector to a lung inflection point monitor; an isolation valve to prevent gas from entering and escaping during a lung inflection point maneuver; and an exhalation valve for regulating the evacuation of gas from the patient.
Claims9
A monitor-patient connector for use with a lung inflection point monitor for measuring critical opening pressure, over distention pressure, and critical closing pressure of lungs, said connector including:
- a proximal opening for connecting to a patient;
- a pressure measuring port, located in a proximal common flow area of the connector that conducts both ingress and egress of gas during respirator treatment;
- a gas injection port for connecting the connector to a lung inflection point monitor;
- and
- at least one isolation/exhalation valve to prevent respirator treatment gas from entering the patient's lungs and to prevent lung inflection point maneuver gas from escaping the patient's lungs during the gas injection phase of the lung inflection point maneuver, and to control the egress of gas during the gas evacuation phase of the lung inflection point maneuver.
A monitor-patient connector for use with a ventilator breathing circuit used in conjunction with a lung inflection point monitor for measuring critical opening pressure, over distention pressure, and critical closing pressure of the lungs, said connector including:
- a proximal opening for connecting to a patient;
- a pressure measuring port located in a proximal area of the connector that conducts both ingress and egress of gas during respirator treatment;
- a gas injection port for connecting the connector to a lung inflection point monitor;
- at least one isolation/exhalation valve to prevent respirator treatment gas from entering the patient's lungs and lung inflection point maneuver gas from escaping the patient's lungs during the maneuver, and to control the escape of gas during the exhalation phase of the maneuver;
- and
- an interface means for connecting the ventilator breathing circuit used in conjunction with the lung inflection point monitor.
A monitor-patient connector for use with a ventilator breathing circuit used in conjunction with a lung inflection point monitor for measuring critical opening pressure, over distention pressure, and critical closing pressure of lungs, said connector including:
- a “Y” shaped connector having a proximal opening for connecting to a patient;
- a pressure measuring port located in a proximal area of the connector that conducts both ingress and egress of gas during respirator treatment;
- a first branch of the “Y” shaped connector having a gas injection port for connecting the connector to a lung inflection point monitor, an inspiratory port for connecting to an inspiratory limb of the ventilator circuit, and an isolation valve to prevent respirator treatment gas from entering the patient's lungs and lung inflection point maneuver gas from escaping the patient's lungs during the maneuver;
- and
- a second branch of the “Y” shaped connector having an expiratory port for connecting to an expiratory limb of the ventilator circuit, and an exhalation valve to prevent respirator treatment gas from entering the patient's lungs and lung inflection point maneuver gas from escaping the patient's lungs during the maneuver, and to control the escape of gas during the exhalation phase of the maneuver.
