A kind of intravascular oxygen supply system and oxygen supply method

Abstract

The invention discloses an intravascular oxygen supply system, which comprises: a high-pressure disinfection chamber, a decompression valve connected to the left side of the high-pressure disinfection chamber, a heater fixedly installed in the high-pressure disinfection chamber, and an oxygen delivery pipe connected to the right side of the high-pressure disinfection chamber. The return pipe, the right side of the return pipe is connected to the oxygen collection chamber through the oxygen delivery pipe, the bottom of the return return pipe is provided with a condensation return pipe, the condensation return pipe is connected to the thermostat through the water delivery pipe, and the thermostat is connected to the water delivery pipe on the condensation return pipe The water pump is fixedly installed on the top, the push box is fixedly installed on the top of the oxygen collection chamber, the rack and pinion pair is fixedly installed in the push box, the piston is fixedly installed in the oxygen collection chamber, the top of the piston is connected with the rack and pinion pair, and the piston is separated from the oxygen collection chamber by a soft film. Open, the right side of the oxygen collection chamber is connected to the oxygen port, and the oxygen port is connected to the blood supply tube. The system adjusts the amount of oxygen delivered by adjusting the oxygen pressure in the pipeline and monitoring the oxygen flow.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an intravascular oxygen supply system and an oxygen supply method. Background technique [0002] At present, the treatment methods for patients with severe type I respiratory failure that cannot be corrected by invasive ventilator therapy mainly include extracorporeal membrane oxygenation and intravascular oxygenator. Extracorporeal membrane oxygenation has the following problems: 1. It is expensive and most hospitals cannot equip it. 2. It needs expensive consumables, which ordinary families cannot afford. 3. It has great damage to red blood cells and requires frequent transfusion of red blood cells. 4. Requires complex operating techniques. 5. The success rate of rescue is low. The following problems exist in the intravascular oxygenator: 1. Due to the limited oxygen provided by the use, about 70-150ml per minute, it cannot fully meet the requirements of critically ill pat...

Problems solved by technology

[0002] At present, the treatment methods for patients with severe type I respiratory failure that cannot be corrected by invasive ventilator therapy mainly include extracorporeal membrane oxygenation and intravascular oxygenator

Extracorporeal membrane oxygenation has the following problems: 1. It is expensive and most hospitals cannot equip it

2. Expensive consumables are required, and ordinary families cannot afford them

3. Great damage to red blood cells, requiring frequent transfusion of red blood cells

4. Requires complex operating techniques

5. Low rescue success rate

The following problems exist in the intravascular oxygenator: 1. Due to the limited oxygen provided by the use, about 70-150ml per minute, it cannot fully meet the requirements of critically ill patients

2. The retention time in the vena cava is limited, about 7-19 days

However, this therapy is mixed in vitro, and the amount of ozone used is limited, which cannot improve the overall oxygen supply of the body.
