Abstract
A breathe assist system is used with a breathe assist control system in providing air to a patient to assist with breathing. The breathe assist control system includes a pressure sensor configured to detect pressure within a patient mask indicative of patient inhalations and exhalations and a controller. The controller is connected to the pressure sensor and to an air supply device for supplying air to the patient mask. The controller receives a pressure signal indicating a pressure detected by the pressure sensor and sends a control signal to the air supply device to control supply of air to the patient mask. An associated breathe assist system and methods are also disclosed.
Claims10
A breathe assist control system to assist in providing air to a patient, comprising:
- a pressure sensor configured to detect a pressure within a patient mask indicative of patient inhalations and exhalations;
- a flow sensor configured to detect a flow rate of fluid through the patient mask;
- a CO2 sensor coupled to the patient mask that is configured to detect a CO2 concentration in the patient's exhalations through the patient mask;
- an air supply device comprising an inflation air bag, a movable member, a stationary member and a flexible cradle for supporting the inflation air bag between the movable member and the stationary member, wherein the movable member is controllable to compress the inflation air bag against the stationary member, and wherein the flexible cradle comprises a pair of crossed straps that directly engage the inflation air bag;
- a controller connected to the pressure sensor and to the air supply device for supplying air to the patient mask, the controller receiving a pressure signal indicating the pressure detected by the pressure sensor and sending a control signal to the air supply device to control the supplying of air to the patient mask,
- wherein the controller is programmed to execute:
- a manual mode in which the air supply device is configured to supply air to the patient according to at least one of a selected breaths per minute rate, an inhale/exhale rate and/or a total volume,
- a patient breathe assist mode in which the air supply device is controlled to produce a breath synchronized with when the pressure signal indicates that the patient is attempting to inhale, and
- a modified patient breathe assist mode in which the air supply device is controlled to produce a breath synchronized with when the pressure signal indicates that the patient is attempting to inhale, modified by a predetermined minimum number of breaths to be produced by the air supply device even if sufficient patient inhalation attempts are not detected.

A breathe assist system to assist in providing air to a patient, comprising:
- a patient mask through which air is configured to be supplied to the patient;
- a pressure sensor configured to detect a pressure within the patient mask indicative of patient inhalations and exhalations;
- a flow sensor configured to detect a flow rate of fluid through the patient mask;
- a CO2 sensor coupled to the patient mask that is configured to detect a CO2 concentration in the patient's exhalations through the patient mask;
- an air supply device connected to the patient mask, the air supply device comprising an inflation air bag, a movable member, a stationary member and a flexible air bag support member extending between the movable member and the stationary member and under a central region of the inflation air bag to hold the inflation air bag between the movable member and the stationary member, wherein the movable member is controllable to compress the inflation air bag against the stationary member to supply air to the patient through the patient mask;
- and
- a controller connected to the pressure sensor and to the air supply device, the controller receiving a pressure signal indicating the pressure detected by the pressure sensor and sending a control signal to the air supply device to selectively control the supply of air to the patient mask,
- wherein the controller is programmed to execute:
- a manual mode in which the air supply device is configured to supply air to the patient according to at least one of a selected breaths per minute rate, an inhale/exhale rate and/or a total volume,
- a patient breathe assist mode in which the air supply device is controlled to produce a breath synchronized with when the pressure signal indicates that the patient is attempting to inhale, and
- a modified patient breathe assist mode in which the air supply device is controlled to produce a breath synchronized with when the pressure signal indicates that the patient is attempting to inhale, modified by a predetermined minimum number of breaths to be produced by the air supply device even if sufficient patient inhalation attempts are not detected.
