The present invention provides new devices, systems, and methods for delivering enriched oxygen to recipients (e.g., chronically ill patients, such as COPD patients). One aspect is a more efficient portable oxygen concentrator that is configured to deliver an enriched oxygen airflow having a significantly lower overall oxygen concentration and greater overall volume administered as compared to currently marketed or known portable oxygen concentrators. Administering the lower oxygen concentration at higher volumes allows for the present portable oxygen concentrators to deliver an equivalent number of moles of oxygen as administered by traditional portable concentrators while increasing the efficiency of the system and the ability of the system to maintain the therapeutic level of oxygen concentration for a longer period.

This utility model discloses an active electromagnetic vibration damping device for a portable oxygen concentrator compressor, including a housing. A connecting wire is inserted into a clamping block, and the other end of the connecting wire is electrically connected to a control system. A permanent magnet is fixedly connected to the middle of the upper end of the compressor, and a vibration displacement sensor is installed on one side of the upper end of the compressor. One end of the vibration displacement sensor is electrically connected to the control system, and the control system is electrically connected to a PLC controller. This portable oxygen concentrator compressor active electromagnetic vibration damping device can form a closed-loop magnetic field area with the permanent magnet through three sets of distributed electromagnetic coils. Vibration displacement can be detected by the vibration displacement sensor, allowing for real-time vibration cancellation through active electromagnetic control technology. Support pads can be used for auxiliary vibration damping, resulting in better performance. Furthermore, the support base frame and support feet can be adjusted for height via support rods and lifting slots, offering excellent adaptability.

A portable oxygen concentrator, including: a battery box, a base assembly, a molecular sieve mechanism, a compressor mechanism, an oxygen storage mechanism, an outer cover, and an operation panel. The compressor mechanism includes a compressor main body and a compressor shell. A side wall of the compressor shell is provided with an opening, where a circuit board is fixed. The compressor main body includes a compressor and a vibration damping assembly arranged at the bottom of the compressor. A first valve assembly is embedded between the compressor main body and the vibration damping assembly, and is connected with the molecular sieve mechanism and an air outlet of the compressor main body. A second valve assembly is embedded between the oxygen storage mechanism and the molecular sieve mechanism, and is connected with an inlet of the molecular sieve mechanism and the oxygen storage mechanism.

A portable medical ventilator that uses pulsed flow from an oxygen concentrator to obtain higher oxygen concentrations, includes a positive pressure source to deliver pressurized air to a patient and a negative pressure source to trigger the oxygen concentrator. A patient circuit attached to a patient interface mask connects the ventilator to the patient. The ventilator includes a controller module configured to generate a signal to the negative pressure device to trigger the concentrator to initiate one or more pulses of oxygen from the oxygen concentrator. The pulses of oxygen are delivered directly to the patient interface through a multi-tube or multi-lumen patient circuit. The oxygen is not mixed with air in the ventilator or patient circuit and bypasses leaks in the patient circuit and / or patient interface.
