Description
Technical field
The utility model relates to therapeutic system, and a kind of centric sleep apnea carbon dioxide sucks and controls specifically
Treat device.
Background technology
Carbon dioxide is respiratory center excitant.Normal respiratory rhythm depends on internal carbon dioxide and maintains constant water
Flat.Within the specific limits, if gas concentration lwevel is too high in blood, Stimulation of The Brain dry chemical receptor causes exaggerated respiration to accelerate；
When in blood, gas concentration lwevel reduction then can cause apnea.Under waking state, gas concentration lwevel reduction in blood is drawn
The respiration inhibition rising can be compensated the normal respiratory movement of maintenance by cerebral cortex excitement.But, in a sleep state, blood
In liquid, gas concentration lwevel declines and can cause sleep apnea.
And patients with heart failure is slept often due to CO 2 reduction in blood, centric sleep apnea is caused frequently to send out
Make, cause interval anoxic, damage heart function the death rate increasing patients with heart failure further.Suck carbon dioxide and can eliminate maincenter
Property sleep apnea event, improves heart function.But, suck too much carbon dioxide and can cause awakening, impact sleep, increase the weight of
The state of an illness；The gas concentration lwevel sucking is too low, can not effectively correct again centric sleep apnea event.Central is caused to sleep
In blood between dormancy apnea and awakening, gas concentration lwevel only has small difference.At present at centric sleep apnea
In treatment, main basis is placed on the pneumatic sensor in nose exit and 2 chest and abdomen bands being bundled in chest and belly respectively
Judge whether patient is in apnea.Pneumatic sensor and chest and abdomen band can cause patient uncomfortable, affect the sleep of patient, and
Coming off of mesothorax abdominal belt of sleep can cause the erroneous judgement of centric sleep apnea event.Therefore, it is badly in need of a kind of energy at present reliable
Discovery centric sleep apnea event device and effective, comfortable carbon dioxide Inhalation in Treating equipment are for central sleep
Apnea patient, particularly heart failure merge centric sleep apnea patient and use.
Utility model content
The purpose of this utility model is the deficiency overcoming above prior art to exist, and provides a kind of central sleep and exhales
Inhale and suspend carbon dioxide inhalation therapy device.This centric sleep apnea carbon dioxide inhalation therapy device can accurately find
Centric sleep apnea event, provides stable, appropriate carbon dioxide to patient, sends out in sleep with effective patient of correction
Raw apnea, is not result in increasing of awakening and microarousal simultaneously.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of centric sleep apnea two
