Real-time oxygen flow rate control system based on arterial blood oxygen partial pressure monitoring

Abstract

The invention provides a real-time oxygen flow rate control system based on arterial blood oxygen partial pressure monitoring. A gas inlet (1) and a gas outlet (3) are connected with a digital oxygen flow rate control valve (2), the digital oxygen flow rate control valve (2) is directly controlled by a main control circuit (4), the main control circuit (4) is connected with a liquid crystal display touch screen (5) arranged on the case for providing a human-computer interaction interface, oxygen gas is sent into a humidifier (7) through the gas outlet (3) after being regulated by the digital oxygen flow rate control valve (2) and is then provided for an oxygen uptake user (8) to be used, a blood oxygen measuring instrument (6) collects arterial blood oxygen partial pressure data from the oxygen uptake user (8) and sends the arterial blood oxygen partial pressure data to a data collecting interface (7), and the data collecting interface (7) is connected with the main control circuit (4). The invention provides a set of solutions for carrying out real-time control on the oxygen flow rate by aiming at the arterial blood oxygen partial pressure demands of different cases, through the real-time arterial blood oxygen partial pressure monitoring, the oxygen flow rate is controlled, and the automatic regulation on a control valve can be set when the arterial blood oxygen partial pressure is greater than or smaller than the standard setting value or the oxygen flow rate is greater than or smaller than the standard setting value.

Description

technical field [0001] The technical solution of the present invention belongs to the technical field of medical oxygen inhalation flow electronic control, and is a real-time oxygen flow control system based on arterial blood oxygen partial pressure monitoring, which is used for the oxygen flow control of the oxygen supply terminal in the center of a medical institution. Background technique [0002] At present, the central oxygen supply system of medical institutions provides oxygen with constant oxygen flow, which cannot flexibly and accurately meet the needs of different cases for oxygen flow. For example, pregnant women cannot inhale oxygen with high oxygen concentration for a long time. Insufficient cases cannot be lower than a certain oxygen flow rate, and the real-time oxygen flow control system can effectively meet this demand and improve medical methods.
