FIELD OF THE INVENTION
The present invention relates to a portable ventilator system, including a ventilator supply system having a ventilator mask, two ambu bags, an air/oxygen source and an air/oxygen regulator system.
BACKGROUND OF THE INVENTION
A ventilator is a machine that provides mechanical ventilation by moving breathable air into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing insufficiently. Modern ventilators are computerized microprocessor-controlled machines, but patients can also be ventilated with a simple, hand-operated bag valve mask. Ventilators are chiefly used in intensive-care medicine, home care, and emergency medicine (as standalone units) and in anesthesiology (as a component of an anesthesia machine).
In its simplest form, a modern positive pressure ventilator consists of a compressible air reservoir or turbine, air and oxygen supplies, a set of valves and tubes, and a disposable or reusable "patient circuit". The air reservoir is pneumatically compressed several times a minute to deliver room-air, or in

most cases, an air/oxygen mixture to the patient. If a turbine is used, the turbine pushes air through the ventilator, with a flow valve adjusting pressure to meet patient-specific parameters. When over pressure is released, the patient will exhale passively due to the lungs' elasticity, the exhaled air being released usually through a one-way valve within the patient circuit called the patient manifold.
Ventilators may also be equipped with monitoring and alarm systems for patient-related parameters (e.g. pressure, volume, and flow) and ventilator function (e.g. air leakage, power failure, mechanical failure), backup batteries, oxygen tanks, and remote control. The pneumatic system is nowadays often replaced by a computer-controlled turbopump.
Modern ventilators are electronically controlled by a small embedded system to allow exact adaptation of pressure and flow characteristics to an individual patient's needs. Fine-tuned ventilator settings also serve to make ventilation more tolerable and comfortable for the patient. In Canada and the United States, respiratory therapists are responsible for tuning these settings, while biomedical technologists are responsible for the maintenance. In the United Kingdom and Europe the management of the patient's interaction with the ventilator is done by critical care nurses.

The patient circuit usually consists of a set of three durable, yet lightweight plastic tubes, separated by function (e.g. inhaled air, patient pressure, exhaled air). Determined by the type of ventilation needed, the patient-end of the circuit may be either noninvasive or invasive.
Noninvasive methods, such as continuous positive airway pressure (CPAP) and noninvasive ventilation, which are adequate for patients who require a ventilator only while sleeping and resting, mainly employ a nasal mask. Invasive methods require intubation, which for long-term ventilator dependence will normally be a tracheotomy cannula, as this is much more comfortable and practical for long-term care than is larynx or nasal intubation.
The simplest mechanical device we could devise to assist a person's breathing would be a hand-driven, syringe-type pump that is fitted to the person's mouth and nose using a mask. A variation of this is the self-inflating, elastic resuscitation bag. Both of these require one-way valve arrangements to cause air to flow from the device into the lungs when the device is compressed, and out from the lungs to the atmosphere as the device is expanded. These arrangements are not automatic, requiring an operator to supply the energy to push the gas into the lungs through the mouth and nose. Thus, such devices are not considered mechanical ventilators.

Automating the ventilator so that continual operator intervention is not needed for safe, desired operation requires three basic components:
• A source of input energy to drive the device;
• A means of converting input energy into output energyTfTthe form of pressure and flow to regulate the timing and size of breaths; and
• A means of monitoring the output performance of the device and the condition of the patient.
There was a time when you could take a handful of simple tools and do routine maintenance on your car engine. About that time the average clinician could also completely disassemble and reassemble a mechanical ventilator as a training exercise or to perform repairs. Today, both cars and ventilators are incredibly complex mechanical devices controlled by multiple microprocessors running sophisticated software. All but the most rudimentary maintenance of ventilators is now the responsibility of specially trained biomedical engineers. Our approach to describing ventilator design has thus changed from a focus on individual components to a more generalized model of a ventilator as a "black box," that is, a device for which we supply an input and expect a certain output and whose internal operations are largely unknowable, indeed, irrelevant, to most clinical operators. What follows, then, is only a brief overview of the key design features of mechanical ventilators with an emphasis on input power requirements, transfer functions (pneumatic

and electronic control systems), and outputs (pressure, volume, and flow waveforms). The rest of the chapter focuses on the interactions between the operator and the ventilator (the operator interface), and between the ventilator and the patient (the patient interface).
Provided is a portable ventilator system, including a ventilator supply system having a ventilator mask, an air/oxygen source and an air/oxygen regulator system, and including a communications device that, during use, automatically contacts an emergency response entity in response to activation of the portable ventilator system. Also provided is a ventilator system that includes at least one ventilator mask, sized to fit upon a selected range of sizes of human faces, a ventilator supply system having an air/oxygen source and an air/oxygen regulator system, and an air/oxygen flow regulation valve having an inlet, an inlet/outlet in communication with a ventilator mask coupled to the ventilator supply system, and an outlet in communication with a surrounding atmosphere. During use, air/oxygen flows through the inlet and the inlet/outlet to facilitate ventilation of a human, and air/oxygen flows through the inlet/outlet and the outlet to facilitate exhalation by a human to the surrounding atmosphere. Further, during use, one of the ventilator masks is coupled to the ventilator supply system to provide air/oxygen to a human, and the air/oxygen regulator system regulates

air/oxygen flow parameters as a function of a size of the ventilator mask coupled to the ventilator supply system.

DETAILED DESCRIPTION OF THE INVENTION
Some embodiments of this disclosure, illustrating all its features, will now be discussed in detail.
This invention relates to improvements in or relating to medical ventilators and, more particularly, to a medical ventilator which is especially, but not exclusively, useful for high frequency ventilation or oscillation of a patient.
Medical ventilators are extensively used in varying circumstances to replace or assist the natural breathing process of a patient in whom this function is impaired.
Under some circumstances and for particular purposes, it is advantageous to ventilate the lungs of a patient at breathing rates which are higher than spontaneous breathing rates with the aid of a high frequency medical

ventilator which may provide breathing rates of up to 3000 breaths per minute (bpm).
A known high frequency medical ventilator or oscillator comprises a ventilator duct which has a patient end for attachment to a patient tube adapted to be introduced into the trachea of a patient whose breathing is to be sustained or augmented by the ventilator. Respiratory gas is introduced into the ventilator duct through two fixed jets extending into the ventilator duct, one of the jets having an outlet orifice facing the patient end of the ventilator duct and the other jet having its outlet orifice facing away from the patient end of the duct. Pulses of respiratory gas are fed alternatively to the two jets so that the patient tube is alternately subjected to high and low pressure, causing an alternating upstream and downstream flow of gas to and from the lungs of the patient in a cyclical way. Other high frequency ventilators are normally closed systems and employ either piston or bellows devices.
While these known high frequency medical ventilators function more or less satisfactorily under some conditions, either they are bulky or the pressure waveform resulting from the alternate pulsing of the two oppositely facing jets is not entirely satisfactory. Also, the synchronization of the pulsed gases supplied to the two jets to maintain the required lung (alveolar) expansion is critical and may be difficult to arrange safely in a clinical situation. The

complexity in the breathing circuit of a closed system has made it unsafe and difficult for routine clinical use.
It is an object of the present invention to provide an improved medical oscillatory ventilator which finds particular application as a high frequency ventilator and, to this end, the invention provides a medical ventilator comprising a ventilator duct having a patient end for attachment to a patient tube ; a respiratory gas supply jet extending into the patient duct and mounted for rotation about an axis transverse to the axis of the ventilator duct, the jet having a gas supply passage terminating in an outlet orifice arranged to direct gas into the ventilator duct in a direction transverse to the axis of rotation of the jet; means for rotating the jet about the axis of rotation; and means for continuously supplying gas to the passage in the jet as the jet rotates to produce a cyclically varying flow of gas to and from the patient end of the ventilator duct.
In an embodiment of the ventilator a gas supply chamber encircles a rotatably mounted shaft of the jet and communicates with the gas supply passage in the jet through radially extending openings in the shaft of the jet.
Preferably, the shaft of the jet is rotatably mounted in a bearing block which is formed with a gas supply conduit extending transversely of the axis of

rotation of the shaft of the jet and which terminates in the gas supply chamber.
The means for rotating the jet conveniently comprises an electric motor.
The present invention ventilator (100) comprises the following essential 5 components:
1. Two ambu bags (101)
2. Linear Accelerators (102)
3. A motor (103)
4. Plurals of Drive (104) I 5. Power supply (105)

6. Stainless steel covers (106)
7. Aluminum Base Plate (107)
8. Rings (108)
9. Aluminum Frame (109)
