Abstract
One or more embodiments of the presently described invention provides a ventilator including a timing device, an electric power source and a flow control device. The timing device is electronically controlled and is capable of controlling a period of time that a fluid is delivered to a patient. The timing device can control this period of time using a solenoid. The flow control device controls a rate of flow that the fluid is delivered to the patient. The flow control device can control the rate of flow using a plurality of orifices. The timing device and flow control device are separate from one another and each is capable of being operated independent of the other.
Claims20
A ventilator apparatus comprising:
- an electrically powered timing control device configured to control a period of time that a fluid is delivered to a patient during inspiratory time periods, the timing control device including a solenoid and an outlet, the timing control device configured to be adjusted to change the inspiratory time periods that the fluid is delivered to the patient, the timing device configured to move the solenoid to a position to block flow of the fluid to the patient during times between the inspiratory time periods;
- and
- a flow control device configured to control a rate of flow that the fluid is delivered to the patient, the flow control device including plural orifices configured to be adjusted to change the rate of the flow that the fluid is delivered to the patient during the inspiratory time periods.
A ventilator apparatus comprising:
- an inspiratory timing control device configured to be fluidly coupled with a patient airway connection that delivers a fluid to a patient, the timing control device configured to start and stop a flow of the fluid to the patient through the patient airway connection, the timing control device configured to receive manual input from an operator that directs the timing control device when to start or stop the flow of the fluid to the patient;
- a flow control device configured to be fluidly coupled with the timing control device and with the patient airway connection, the flow control device having a first outlet configured to be fluidly coupled with the patient airway connection, plural orifices having different sizes, and a different second outlet, the flow control device configured to receive the fluid from the timing control device and control a rate of the flow of the fluid to the patient through the first outlet and the patient airway connection;
- and
- a patient airway pressure sensor fluidly coupled with the second outlet of the flow control device, the patient airway sensor configured to receive at least some of the fluid passing through one or more of the orifices of the flow control device and exiting the flow control device through the second outlet, the pressure sensor configured to measure a pressure of the fluid delivered to the patient based on the fluid received from the second outlet.
A method of providing a ventilator apparatus, the method comprising:
- fluidly coupling an inspiratory timing control device with a patient airway connection that delivers a fluid to a patient, the control device configured to start and stop a flow of the fluid to the patient through the patient airway connection;
- fluidly coupling a flow control device with the timing control device and with the patient airway connection, the flow control device having a first outlet configured to be coupled with the patient airway connection and plural orifices having different sizes, the flow control device configured to receive the fluid from the timing control device and control a rate of the flow of the fluid to the patient through the first outlet and the patient airway connection;
- and
- fluidly coupling a patient airway pressure sensor with the flow control device, the patient airway sensor configured to receive at least some of the fluid passing through one or more of the orifices of the flow control device and exiting the flow control device, the pressure sensor measuring a pressure of the fluid delivered to the patient based on the fluid received from the second outlet.
