Problems solved by technology

Although the existing multi-parameter monitors and pulse oximeters can effectively monitor the dynamic blood oxygen value, but because the oxygen output control is an independent system, the control and control of the target blood oxygen value cannot be effectively achieved in the clinical practice of oxygen therapy. keep stable

Embodiment 1

[0025] Embodiment 1: According to the actual clinical practice, an example is further combined with Table 1 "Control Algorithm".

[0026] 1. According to clinical needs, the control algorithm sets the target blood oxygen value as the following 6 optional treatment options, among which the treatment plan numbers (1) to (5) only need to select the target blood oxygen value, set the doctor’s order flow value, inhale Oxygen therapy can be started after the oxygen duration.

[0027] (1) The target blood oxygen value of oxygen therapy for patients undergoing anesthesia recovery is set at 96%, and the allowable deviation value is + 1%;

[0028] (2) The target blood oxygen value of patients on routine oxygen inhalation is set at 95%, and the allowable deviation value is + 1%;

[0029] (3) The target blood oxygen value for neonatal oxygen therapy is set at 93%, and the allowable deviation is + 1%;

[0030] (4) The target blood oxygen value of oxygen therapy for patients with acute...

Abstract

The invention provides an intelligent oxygen therapy system with a target blood oxygen value as a precise control point. The intelligent oxygen therapy system is mainly composed of a control system, ablood oxygen monitoring module, a flow control valve, a flow metering module, an illumination sensor, a human-computer interaction interface and a communication module. After the target blood oxygenvalue, a flow value of doctor's advice and an oxygen inhalation durance are set on the human-computer interaction interface according to characteristics of a patient, the control system intelligentlycontrols an oxygen therapy working state according to a pre-written control algorithm to judge a matched state of a dynamic blood oxygen value and the target blood oxygen value, and when the dynamic blood oxygen value deviates from a target blood oxygen control interval value for intervention control time, the control system automatically adjusts the output flow within a flow correction interval and according to a flow correction gradient, so that the dynamic blood oxygen value of the patient is precisely controlled within the range of the target blood oxygen control interval value, and the effectiveness and safety of oxygen therapy are improved.

Description

technical field [0001] The invention relates to an intelligent oxygen therapy system with a precise control point based on a target blood oxygen value, which belongs to a medical device used in clinical oxygen inhalation therapy. Background technique [0002] Oxygen inhalation therapy (referred to as "oxygen therapy") is one of the most commonly used rescue or treatment methods in hospitals. Its purpose is to improve the patient's ambulatory blood oxygen value and keep it within a reasonable range by inhaling oxygen to the patient, and correct various causes. Oxygenation caused by abnormal state, to maintain the body's life activities. At present, oxygen therapy in China is basically in a state of no rules. Even most medical staff believe that oxygen therapy is beneficial and harmless. The more oxygen given, the better the therapeutic effect. In most cases of clinical practice, there is no strict doctor's order for oxygen therapy. The entire oxygen therapy process lacks str...
