An emergency respirator ventilator that comprising an air cylinder and piston/piston rod for compressing an air bag to transmit air to a patient, e.g., during situations where fully equipped ventilators are not immediately available.

In some examples, a ventilator includes a pneumatic connection configured to receive supply gas; an inspiratory path configured to deliver conditioned gas to lungs of a patient; a valve pneumatically connected to the pneumatic connection and configured to allow flow of the supply gas to the inspiratory path when the valve is open and block flow of the supply gas to the inspiratory path when the valve is closed; a pressure sensor configured to measure a pressure of the supply gas at the pneumatic connection; and electronic control circuitry configured to control an opening and closing of the valve based on the measured pressure to produce a desired volume of conditioned gas in the inspiratory path.

The present invention relates to the art of automatic regulation of pulmonary devices for assisting and/or enforcing the breathing process by converting Bag-Valve-Mask (BVM) apparatus are also known as manual resuscitators to automatic system by pneumatic matter with the goal to enhance both phases of breathing: inhalation and exhalation. It also replaces a mechanical chest compression for automatic pneumatic compression, could be complimented with the use of the TENs unit and can be used for extended periods of time with a high level of reliability, simplicity, efficacy and low cost.

This portable and light device is recommended to be used as a resuscitator attached to the patients with mild to extremely suppressed or without respiratory drive.

The source of power can be electrical, battery operated, manual or a combination thereof.

That feature is extremely critical for its use in a combat zone or during a power failure.

A system and method for ventilating includes a holding tank, such as, for example, a medical sealed apparatus, for storing of gases. The holding tank stores at least pressured oxygen, for example O.sub.2, though the holding tank may store a pressurized blend of oxygen and air. This blend may include a 50-50 mix of oxygen and air. The pressure applied to the gases in the holding tank may include a range from 5 pounds force per square inch to 20 pounds force per square inch. The blend of oxygen and air, for example, under pressure in the holding tank, the system and method for ventilating of the present disclosure no longer requires an electronic mechanical system, such as, for example, a pump or motor on the inhalation control and the exhalation control to the ventilating system and method.

A ventilator system including an oxygen delivery cylinder, an air delivery unit, connecting tubes, and a digital display unit. The system further includes a Y connector configured to mix air and oxygen, to form a gas and pass said gas towards an outlet of the system. A water manometer that is configured to monitor a pressure of the gas in the system and blow off the excess pressure of the gas. A solenoid valve that is configured to adjust an end respiratory pressure obtained from a breathing device connected to the outlet of the system. The pressure of the gas being instantly delivered to the breathing device is measured by water manometer from a dead space near the outlet, thereby enabling a dual monitoring of the gas pressure being delivered to the breathing device.

In general, one aspect disclosed features a scalable ventilator system, comprising: a plurality of ventilator modules; a controller to control operation of the plurality of ventilator modules; and a station module comprising a plurality of receptacles, wherein each receptacle is configured to accept one of the plurality of ventilator modules; wherein each ventilator module comprises a plurality of solenoid valves and an input hose and an output hose, wherein each ventilator is controlled individually to provide individualized regimens based on needs of a patient corresponding to a respective ventilator.

A patient ventilation system includes a ventilator configured to deliver ventilation gas to patient, a CO.sub.2 concentration sensor configured to provide EtCO.sub.2 measurements for the patient, and an SpO.sub.2 monitor configured to determine an SpO.sub.2 value for the patient. A ventilation control module is executable on a processor and configured to compare the SpO.sub.2 value to a threshold SpO.sub.2 and determine from this comparison that the SpO.sub.2 value indicates inadequate oxygenation. A minimum ventilation amount is then set, and the ventilator is then controlled based on the EtCO.sub.2 measurements and the minimum ventilation amount so as to deliver at the least the minimum ventilation amount to the patient while the SpO.sub.2 value indicates inadequate oxygenation.

The invention relates to a method for operating an actuator (22) in a medical apparatus (20), the actuator (22) being connected to a tube system. The medical apparatus (20) comprises: a control apparatus (28) having a pressure controller (35) for controlling a gas pressure; and a computing system (30). The method comprises the following steps: providing a nasal cannula at the tube system; defining a nasal gas end pressure at the pressure controller (35); controlling a nasal gas pressure at the actuator (22) by means of the pressure controller (35), in particular toward the nasal gas end pressure; discharging a conditioned gas from the actuator (22) to the tube system. The invention further relates to a device for operating the actuator (22).

An electro-magnetic induction device for activating a target tissue in a body via its muscular or neural system includes an electro-magnetic field generator with a coil design configured to generate an electro-magnetic field, a mounting arrangement holding the coil design at the body, a sensor member configured to detect an activation of a target tissue, an electro-magnetic field adjustment mechanism configured to automatically adjust the position and a field strength of the electro-magnetic field, and a calibration unit in communication with the sensor member and the electro-magnetic field adjustment mechanism. The calibration unit is configured to control the electro-magnetic field adjustment mechanism to automatically vary the position and the field strength of the electro-magnetic field, to receive an activation feedback signal from the sensor, and to control the electro-magnetic field adjustment mechanism to automatically stop variation of the position of the electro-magnetic field generated by the coil design.
