Problems solved by technology

High-frequency jet ventilation adopts the "Venturi" principle to comprehensively influence the interaction of diseases and treatments, but high driving pressure and high frequency may occur, which may lead to complications such as barotrauma and hypercapnia
Some foreign scholars suggested the use of extracorporeal membrane lungs and replacement of carbon dioxide through the internal jugular vein, but they cannot be widely used due to the disadvantages of large damage, high cost, and difficulty in popularization.
Currently produced jet ventilators are only in single-frequency jet mode, which cannot solve the risks brought by high-frequency jet ventilation

Embodiment Construction

[0020] The following describes the present invention in detail, and the features and advantages of the present invention will become more clear and definite along with these descriptions.

[0021] According to the first aspect of the present invention, such as figure 1 As shown, a respiratory workstation is provided, which has a constant-frequency jet mode and a constant-frequency / ECG-triggered composite jet mode, including a monitoring system and a dual-way jet ventilation system, wherein,

[0022] The monitoring system is used to receive the original data of the human body's electrocardiogram, analyze the original data of the electrocardiogram, extract the data of the cardiac cycle and the switching point of the single / dual frequency jet mode, and send it to the dual jet ventilation system; among them, the switching point of the single / dual frequency jet mode Located in the time period after the corresponding R wave band in the cardiac cycle;

[0023] The dual-way jet venti...

Abstract

The invention provides a respiration work station and an oxygen supply method thereof. The respiration work station has a normal-frequency jet mode and a normal frequency / electrocardio trigger compound jet mode. A monitoring system receives human body electrocardiogram original data, analyzes the electrocardiogram original data, extracts a cardiac cycle and single / double frequency jet mode transition point data and sends the cardiac cycle and single / double frequency jet mode transition point data to a double-channel jet ventilation system. The double-channel jet ventilation system receives the cardiac cycle and single / double frequency jet mode transition point data sent by the monitoring station, combines the cardiac cycle and single / double frequency jet mode transition point data with aninput respiratory quotient to determine a double / single frequency jet mode transition point, implements transition from the normal frequency jet mode to the normal frequency / electrocardio trigger compound jet mode at the single / double frequency jet mode transition point and implements transition from normal frequency / electrocardio trigger compound jet mode to the normal frequency jet mode at the double / single frequency jet mode transition point. By the adoption of the respiration work station and the oxygen supply method thereof, the jet mode is adjusted according to the physiological stateof a user, and the purpose of improving the survival rate of patients is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a breathing workstation for rescue or auxiliary operation and an oxygen supply method thereof. Background technique [0002] With the wide application of jet ventilation, supraglottic jet ventilation is recommended by experts and scholars for airway interventional therapy, first aid for patients with respiratory arrest, and treatment for critically ill patients. In airway interventional therapy, anesthesia and treatment share a narrow airway, and the airway is open, and continuous high-frequency jet ventilation is used as a respiratory support method. High-frequency jet ventilation adopts the "Venturi" principle, which integrates the interaction of diseases and treatments, but high driving pressure and high frequency may occur, which may lead to complications such as barotrauma and hypercapnia. Some foreign scholars suggested the use of extracorporeal membrane lungs and ...
