Abstract
Provided are a method for controlling an oxygen provider and a portable device. The method includes: acquiring measurement data at a patient side; determining an oxygen demand volume and an output pattern of an oxygen provider based on the acquired measurement data and a desired oxygen fraction ratio; and controlling the oxygen provider with the oxygen demand volume and the output pattern. With the method or device for controlling an oxygen provider, oxygen with an amount that actually needed by a patient is provided to produce the blended gas to be delivered to the patient, and the blended gas delivered to the patient are regulated according to the output pattern to guarantee the blended gas is delivered in synchronization with the inspiration of the patient, so that a therapeutic effect is achieved with a lower oxygen consumption amount.
Core Innovation
The invention relates to an oxygen therapy control method for controlling an oxygen provider that comprises an oxygen source and a blower device. The method acquires measurement data at a patient side of the oxygen provider, determines an oxygen demand volume and an output pattern of the blower device based on the acquired measurement data and a desired oxygen fraction ratio, and controls the oxygen source and blower device to output blended gas that is a mixture of oxygen and air.
The determining includes determining a blended gas demand volume, an inspiration time, and a breathing period based on the measurement data. The oxygen demand volume is determined based on the blended gas demand volume and the desired oxygen fraction ratio, and the output pattern of the blower device is determined based on the blended gas demand volume, the inspiration time, and the breathing period.
The output pattern comprises a blower flow and a blowing period, and the blower flow and blowing period are determined based on the blended gas demand volume, the inspiration time, and the breathing period. The control further comprises determining a duty cycle of the oxygen source based on the oxygen demand volume and the inspiration time, and controlling the oxygen source to operate according to the duty cycle.
Claims Coverage
The partial content includes four independent claims: a method claim, a controlling device claim, and a portable device claim, with overlapping coverage to the same control scheme. The claims center on controlling an oxygen provider by determining oxygen demand volume and a blower output pattern from patient-side measurement data and a desired oxygen fraction ratio, and then using those determinations to control the oxygen source and blower device to output blended gas.
Patient-side measurement driven oxygen demand volume and blower output pattern
Acquiring measurement data at a patient side of the oxygen provider; determining an oxygen demand volume and an output pattern of the blower device based on the acquired measurement data and a desired oxygen fraction ratio; and controlling the oxygen source and blower device to output blended gas, wherein the blended gas is a mixture of oxygen and air.
Blended gas demand volume and timing parameter determination for control
Determining a blended gas demand volume, an inspiration time, and a breathing period based on the measurement data; determining the oxygen demand volume based on the blended gas demand volume and the desired oxygen fraction ratio; and determining the output pattern of the blower device based on the blended gas demand volume, the inspiration time, and the breathing period, wherein the output pattern comprises a blower flow and a blowing period.
Duty cycle and blower flow/period control synchronized to inspiration and breathing period
Determining a duty cycle of the oxygen source based on the oxygen demand volume and the inspiration time; controlling the oxygen source to operate according to the duty cycle; and controlling the blower device to output the blended gas according to the blower flow and the blowing period.
Controller architecture for implementing the oxygen provider control
A controlling device with at least one processor and a memory storing instructions executable by the at least one processor, wherein the instructions cause the processor to acquire measurement data at a patient side of the oxygen provider, determine an oxygen demand volume and an output pattern of the blower device based on the acquired measurement data and a desired oxygen fraction ratio, and control the oxygen source and blower device to output blended gas comprising oxygen and air.
Across the independent claims, the core claimed coverage is a control scheme for an oxygen provider that uses patient-side measurement data and a desired oxygen fraction ratio to determine an oxygen demand volume and a blower output pattern. The coverage further includes blended gas demand volume and timing parameters such as inspiration time and breathing period, together with duty cycle control of the oxygen source and blower flow and blowing period control of the blower device.
