Definitions
- This invention relates to an apparatus, method and system for assisting a patient's 5 breathing and, more particularly, for assisting breathing without contacting the patient.
- amyotrophic lateral sclerosis also known as Lou Gehrig's disease
- assistance typically takes the form of forcibly inflating and deflating the patient's lungs
- a system for directing a pressurized stream of gas at a patient's mouth to assist in breathing.
- the system includes a source of the gas stream; a conduit for conveying the stream from an
- the device includes a conduit for conveying the gas stream from an inlet, connected to a gas source, to an outlet directing the stream toward the patient' s mouth; a sensor for detecting a respiratory need of the patient; a by-pass vent for venting the stream when breathing assistance is not required; a valve inserted in the conduit for dividing the stream between the outlet and the vent; and a controller for controlling the valve that is actuated based on the respiratory need of the patient.
- a method for directing a pressurized stream of a gas at a patient's mouth to assist in breathing.
- the method comprises sensing a respiratory need of the patient; controlling a flow of the stream based on the respiratory need of the patient; and directing the stream toward a vicinity of the patient's mouth.
- Fig. 1 shows a sectional side view of one embodiment of the present invention
- Fig. 2 shows a sectional side view of another embodiment of the present invention
- Fig. 3a shows an angle view of a nozzle in an embodiment of the present invention
- Fig. 3b shows a top view of the nozzle in an embodiment of the present invention.
- the present invention advantageously addresses the cited problems with breathing assistance systems for patients with diseases involving muscular degeneration.
- the need for an invasive mask or other device connected to the patient's airway is eliminated and patient control of breathing assistance is facilitated.
- Fig. 1 shows a sectional side view of one embodiment of the present invention which directs a pressurized stream of gas at a patient's mouth 10.
- a source 20 of a stream of pressurized gas such as a pump or a pressurized gas cylinder or a fan, is provided.
- the gas may be atmospheric air or an air-oxygen mixture, or another gas.
- the gas source 20 is coupled to a conduit 30 via an inlet 35 so that gas may be introduced into the conduit.
- the conduit conveys the gas to an outlet 40, such as a nozzle.
- the term "conduit" as used in this description and in any appended claims, will be understood to include any element that functions as a channel that conveys gas, including, without limitation, a hose, a tube and a pipe.
- a valve 50 in the conduit modulates the stream of gas including varying the flow rate or pressure and additionally turning the flow off and on.
- a sensor 60 senses a respiratory need of the patient and signals a controller 70 typically via an electromagnetic channel.
- sensors 60 may include, for example without limitation, a microswitch triggered by contact with the patient's mouth or another part of the patient's body or an infrared detector that detects proximity of the patient's head or a motion sensor that detects movement of the patient's.
- the controller 70 receives the signal from the sensor 60 indicating the patient's respiratory need, the controller opens the valve, either partially or fully, thereby directing the pressurized stream of gas at the patient's mouth, providing assistance in inflating the patient's lungs.
- a rotary blower pump generates a continuous gas stream of approximately 3.5 liters per second at a pressure of up to 60 inches of water.
- a nozzle as the conduit outlet, directs the gas stream at the patient's mouth.
- Fig. 3a shows an angle view of the nozzle 200, which is made of plastic.
- One end of the nozzle 210 mates with the conduit, while the other end 215 directs gas at the patient.
- Fig 3b shows a top view of the nozzle.
- the stream of gas With the nozzle positioned two to three inches from the patient's mouth, the stream of gas provides mechanical assistance to the patient in inflating the patient's lungs, when the stream is turned on.
- Fig. 2 shows another preferred embodiment of the invention.
- This embodiment further comprises a by-pass vent 100 inserted in the conduit 30.
- the valve 50 divides the gas stream between the outlet 40 and the by-pass vent 100.
- This arrangement allows the gas source 20, if, for example, it is a pump, to supply a continuous stream of gas, thus extending the life of the pump.
- the valve 50 and by-pass vent 100 may be located in the conduit near the gas source, remote from the outlet 40, to reduce noise and any disturbance to the patient from the gas stream emitted by the by-pass vent 100.
