Abstract
The invention discloses a dual-function continuous positive pressure respirator. The dual-function continuous positive pressure respirator is characterized in that the dual-function continuous positive pressure respirator comprises a filter and a regulator; the filter is used for filtering out impurities in the air, so that purified air enters the regulator; the regulator is used for compressing the air and regulating the air inflow amount according to the respiratory rate of a patient so that the purposes that air inflow amount is small during expiration and is large during inspiration and air passing through the regulator directly enters the body of the patient through a nasal mask can be achieved; the regulator is connected with the filter and the nasal mask through soft tubes. The dual-function continuous positive pressure respirator is reasonable in design, can accurately judge breath accidents and timely adjust compressed air with proper pressure and effectively meets requirements of patients poor in lung function, patients having lung failure and patients with sleep apnea syndromes.
Description
Technical field
The present invention relates to a kind of two horizontal continuous positive pressure breathing machine, relate in particular to patient's respirator for keeping smooth and easy breathing to use under sleep state that the reasons such as a kind of applicable pulmonary function is poor, lung failure, sleep apnea syndrome cause respiratory disorder, belong to household type medical instruments field.
Background technology
Snoring is a kind of ubiquitous sleep phenomenon, and most people thinks that this is quotidian, and takes exception to, and somebody regards snoring as the performance sleeping soundly.Snoring is healthy formidable enemy in fact, and at present, along with people are to hypopnea, the raising of the understanding that can cause various diseases as snored often can be used respirator in family care.The reason of snoring generally can be divided into three kinds: the one, because patient airway diminishes, as caused by diseases such as nasal polyps; The 2nd, due to indoor anoxia, while causing patient to sleep, open one's mouth to breathe; The 3rd, the sleep apnea syndrome of being controlled by vegetative nerve, the snoring again after the meeting that suffocates, this situation is very serious, is even in peril of one's life, and night respiration time out surpasses easily dies suddenly in morning for 120 seconds; In addition, because snoring makes sleep-respiratory, repeatedly suspend, cause brain, blood severe depletion of oxygen, form hypoxemia, and bring out the various diseases such as hypertension, diabetes, brain cardiopathia, arrhythmia, myocardial infarction, angina pectoris.Therefore, the harm of snoring can not be ignored, the use of household type respirator is also more and more general, respirator is a kind of artificial mechanical ventilation device, for autonomous respiration campaign auxiliary or control patient, to reach the function of gas exchange in lung, reduce the consumption of human body, be beneficial to the recovery of respiratory function.
Utilize that respirator treatment pulmonary function is poor, lung failure, sleep apnea syndrome patient's treatment principle is: respirator produces suitable continuous positive pressure venti lation (comprise constant malleation, change malleation etc.), through nasal mask or oral nose mask, offer patient, can effectively avoid patients with respiratory tract to subside or partly subside, thereby guaranteeing that patient respiratory is unobstructed.The respirator of the respiratory disorder that the reasons such as treatment is poor by pulmonary function, lung failure, sleep apnea syndrome cause is two level respirators, the concept of two level respirators is for patient provides the higher pressure of inspiration(Pi) that sets and lower expiratory pressure, conversion automatically in patient respiratory process.But; because patient's physiology of respiration complexity is higher; airway resistance often can constantly boost, reduces pressure, cause pressure oscillation more due to state impacts such as sleeping posture change, drinks, and the product of each producer all exists the defect that cannot meet therapeutic effect in various degree at present.
In sum, because existing respirator cannot carry out the judgement of respiration case accurately, respiration case judges that patient is expiration state or suction condition, therefore causes meeting patient demand completely.
Summary of the invention
Technical problem to be solved by this invention is, a kind of reasonable in design, two horizontal continuous positive pressure breathing machine of accurately judging respiration case is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
