APPARATUS AND METHOD FOR OXYGEN DELIVERY

摘要

The oxygen delivery apparatus comprises: an oxygen tank; an outlet valve unit configured to include a variable flow valve capable of variably controlling the amount of oxygen, a pressure sensor, and a control unit controlling the operation of the outlet valve unit on the basis of a signal from the pressure sensor in order to control the amount of oxygen delivered to a recipient. The control unit controls the outlet valve unit on the basis of the pressure signal and an oxygen delivery mode selected from among a plurality of preset oxygen delivery modes, receives a prescribed flow (that is a prescribed oxygen delivery flow) and a target average consumed flow, selects one of the plurality of oxygen delivery modes according to the size of a obtained saving ratio obtained as ratio of the input prescribed flow and the target average consumed flow, and controls the delivery of oxygen on the basis of the selected mode.

1. An oxygen delivery apparatus comprising:
an oxygen tank storing oxygen; an outlet valve unit configured to include a variable flow valve capable of variably controlling the amount of oxygen delivered from the oxygen tank to a recipient; a pressure sensor detecting a breathing pressure of the recipient and outputting a pressure signal corresponding to the breathing pressure; and a control unit controlling the operation of the outlet valve unit on the basis of the pressure signal from the pressure sensor to control the amount of oxygen delivered to the recipient, wherein the control unit controls the outlet valve unit on the basis of the pressure signal and an oxygen delivery mode selected from among a plurality of preset oxygen delivery modes, receives a prescribed flow (Qp) (that is a prescribed oxygen delivery flow) and a target average consumed flow (Qs), selects one of the plurality of oxygen delivery modes according to the size of a obtained saving ratio (Qp/Qs) obtained as ratio of the input prescribed flow and the target average consumed flow, and controls the delivery of oxygen on the basis of the selected mode.
