Embodiment Construction

[0019] The working process of the extracorporeal circulation self-oxygenation system of the present invention will be further described below in conjunction with the accompanying drawings:

[0020] The present invention includes oxygenator 1, chemical oxygen generator 8, figure 1 It is a schematic diagram of the working process of the oxygenator in the prior art, Figure 2-Figure 3 Shown is a schematic diagram of the structure and working principle of the chemical oxygen generator of the present invention. The chemical oxygen generator of the present invention is similar to the Kipp generator. During use, ordinary water 12 is injected from the water injection port 16, enters the bottom of the chemical oxygen generator 8 through a conduit and contacts with the bottom of the chemical oxygen generator 11, and passes through the following reaction Oxygen is produced:

[0021] 4KO 2 (s)+2H 2 O(1)=4KOH(s)+3O 2 +Q1 (1)

[0022] The generated oxygen 13 enters the oxygenator 1 th...

Abstract

The invention belongs to the medical appliance technique field, relates to an extracorporeal circulation self supporting oxygen system that can be used for treating fearful pulmonary function harm at the scene. The system includes an oxygenator, a vein conduction blood vessel, an artery infusion blood vessel and a chemical oxygen generator. An oxygen outlet of the chemical oxygen generator connects with an oxygen inlet of the oxygenator through pipe and adjustable valve, an oxygen inlet of the chemical oxygen generator connects with an oxygen exhaust of the oxygenator through pipe. The system gains precious time for rescuing critical patient and prolonging life, at the same time, residual oxgen after patient using and exchanged CO2 gas is lead to the chemical oxygen generator through pipe for using again, CO2 is absorbed fully, and residual oxygen is continuous used repeatedly.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an extracorporeal circulation self-oxygenation system that can be used for on-site rescue of lung function damage. Background technique [0002] Severe pulmonary dysfunction is more common in peacetime and wartime. Maintaining normal respiratory function is the main content of disaster medical rescue and war trauma rescue. However, the current medical rescue techniques and means for respiratory function are very limited, such as closed chest drainage, percutaneous cricothyroid puncture, pressurized masks, etc. , these technologies can indeed play an emergency and life-saving effect on the on-site rescue of some wounded and sick. However, if the wounded suffers from structural damage such as open chest wall injury, lung parenchyma damage, or severe damage to respiratory function, these techniques alone cannot achieve the treatment effect, and may cause on-site death of such...
