Mobile head-shield oxygen uptake systemTechnical field
The present invention relates to the oxygen uptake systems more particularly to a kind of mobile head-shield oxygen uptake system in medical field.
Background technique
Currently, medical institutions mostly use physical therapy mode rehabilitation sexual health to treat chronic disease, whole body or office are accelerated with thisPortion tissue blood circulation and obtain a degree of curative effect.But chronic disease almost all exists with histoorgan without exception to be lackedAnoxemia is related, wherein many chronic diseases are the organopathies for occurring to leave after damage or angiogenesis obstruction because of histoorganChange, is mainly characterized by local organization blood supply insufficiency and there are histocyte anoxics, therefore, to chronic disease, especially to damageWound or blood vessel blockage are chronic ischemia ischemic disease caused by cause, take positive carbon dioxide mix oxygen therapy that will have weightThe clinical meaning wanted, carbon dioxide mix oxygen can play the double treatment effect of " improve blood circulation and improve blood oxygen tension ".
The purpose of carbon dioxide mix oxygen therapy is to improve blood oxygen tension using oxygen, improve blood using carbon dioxideCirculation.It is that human body establishes oxygen differential pressure gradients certain between blood and oxygen-starved tissue by oxygen, improving blood oxygen tension is to establishThe important measures of this differential pressure gradients, in this way, oxygen can be made largely to be dissolved among the tissue of anoxic, thus to terminate diseasePathological change or disease recovery from illness lay the foundation.Human bloodstream amount etc. is reduced no since breathing pure oxygen or raising blood oxygen tension can generateTherefore good influence when treating chronic ischemia ischemic disease, need to be implemented effectively to improve blood while improving blood oxygen tensionFlow measure.According to measurement, human body breathes pure oxygen under normal pressure, and heart rate can slow down on the original basis 5%-16%: blood flow10% can be reduced.Human body blood oxygen tension is higher, and the degree that blood flow reduces is just bigger.
In the past, clinically either in normal pressure, or under hyperbaric environment carry out oxygen uptake process, be substantially all and do not haveIt is standby provide simultaneously can effectively or it is synchronous improve sanguimotor method, human body blood can only be improved for patient respiration pure oxygen merelyOxygen tension.Since the raising of human body blood oxygen tension necessarily will affect blood circulation, and the nutriment in blood circulation is human bodyThe basis of histocyte metabolism, only improve blood oxygen tension without having improvement blood circulation will affect sanguimotor treatment insteadMethod would become hard to reach therapeutic purposes to chronic ischemia ischemic disease.For chronic ischemia ischemic disease, tissue is lackedOxygen is not that uniquely, nutriment and oxygen are all indispensable one cell metabolism bases in blood.
