Controllable oxygen transferring throttling system

Abstract

The invention provides a controllable oxygen transferring throttling system. The controllable oxygen transferring throttling system comprises a blood oxygen parameter controller and an oxygen flow control device receiving signals of the blood oxygen parameter controller, one end of the oxygen flow control device is connected with an oxygen pump, the other end of the oxygen flow control device is connected with an oxygen uptake tube, a main board is arranged in the oxygen flow control device, and a display screen is arranged outside the main board; the main board is connected with a flow control valve, an operation key and a buzzer, and the main board receives blood oxygen signals of the blood oxygen parameter controller; the blood oxygen parameter controller is connected with a monitor or a blood oxygen finger clip. According to the controllable oxygen transferring throttling system, oxygen transferring is controlled according to the blood oxygen content of a patient; after the blood oxygen content of the patient reaches a normal value, doctors can set an oxygen transferring switch according to practical requirements, and oxygen transferring time is adjusted automatically.

Description

technical field [0001] The invention belongs to the field of medical monitoring, in particular to a controllable oxygen delivery throttling system. Background technique [0002] Oxygen inhalation is used to correct hypoxia, increase arterial oxygen partial pressure and oxygen saturation levels, and promote metabolism. It is one of the important methods for auxiliary treatment of various diseases. Such as respiratory failure, chronic bronchitis, cerebrovascular disease, coronary heart disease. Those with no obvious symptoms of clinical hypoxia may also have oxygen debt, and may also have abnormal microcirculation metabolism, so oxygen inhalation may be required. Such as patients before and after certain surgical operations, patients with hemorrhage and shock, patients with poor fetal heart sounds or prolonged labor during childbirth, etc. [0003] Blood oxygen saturation (SaO2) is the percentage of the capacity of oxygen-bound oxyhemoglobin (HbO2) in the blood to the total ...

AI Technical Summary

Problems solved by technology

However, in severe hypoxic conditions, due to the accumulation of lactic acid in the subendocardium, the synthesis of ATP decreases, resulting in myocardial inhibition, resulting in bradycardia, premature contraction, decreased blood pressure and cardiac output, and arrhythmias such as ventricular fibrillation even stop

[0006] In addition, hypoxia and the patient's own disease may have an important impact on the patient's homeostasis

[0007] However, when the patient's blood oxygen concentration reaches saturation, there is no need to continue to supply oxygen, and continuing to supply oxygen will cause a waste of oxygen and may cause oxygen toxicity.

[0008] The existing oxygen input method is to directly connect the oxygen to the patient's mouth and nose. When the blood oxygen value of the patient returns to normal, the oxygen will not stop until the nurse cuts off the oxygen flow. This method cannot meet the actual condition of the patient's body. Oxygen delivery in real time

Can lead to overdelivery and waste of oxygen
