Description
Technical field
The present invention relates to a kind of two persistent levels positive pressure respirator, particularly relate to the reasons such as a kind of applicable pulmonary function is poor, lung failure, sleep apnea syndrome and cause the respirator of the patient of respiratory disorder in a sleep state for keeping smooth and easy breathing to use, belong to household type medical instruments field.
Background technology
Snoring is a kind of ubiquitous sleep phenomenon, and current most people thinks that this is quotidian, and takes exception to, and somebody regards snoring the performance slept soundly as.Snoring is healthy formidable enemy in fact, at present, along with people are to hypopnea, as snoring can cause the raising of the understanding of various disease, in family care, often can use respirator.The reason of snoring generally can be divided into three kinds: one to be because patient airway diminishes, as caused by diseases such as nasal polyps; Two is due to indoor anoxia, causes opening one's mouth during patient sleeps to breathe; Not only three is the sleep apnea syndromes controlled by vegetative nerve, and suffocate one after the meeting but also snore, this situation is very serious, and be even in peril of one's life, night respiration time out was easily died suddenly in morning more than 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 that is 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 treatment principle be: respirator produces suitable continuous positive pressure venti lation (comprising constant positive pressure, change malleation etc.), patient is supplied to through nasal mask or oral nose mask, can effectively avoid patients with respiratory tract to subside or partial collapse, thus ensure that patient respiratory is unobstructed.Treat the respirator of the respiratory disorder that the reasons such as, lung failure, sleep apnea syndrome poor by pulmonary function cause for two level respirators, the concept of two level respirator is for patient provides the higher pressure of inspiration(Pi) and lower expiratory pressure set, and automatically changes in patient respiratory process.But; because the physiology of respiration complexity of patient is higher; the states such as airway resistance often can change due to sleeping posture, drink impact and constantly boost, reduce pressure, cause pressure oscillation more, all there is the defect that cannot meet therapeutic effect in various degree in the product of each producer at present.
In sum, because existing respirator cannot carry out the judgement of respiration case accurately, namely respiration case judges that patient is expiration state or suction condition, therefore causes to meet patient demand completely.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of two persistent levels positive pressure respirators of judgement respiration case reasonable in design, accurate.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of two persistent levels positive pressure respirator, is characterized in that: comprising:
Filter: for filtering the impurity removed in air, enter actuator after air is filtered;
Actuator: for compressed air and according to patient respiratory frequency adjustment air inflow, when realizing exhaling, air inflow is little, and during air-breathing, air inflow is large, and the air through actuator directly sucks in patient body by nasal mask;
Described actuator passes through hose connection with filter and nasal mask respectively.
Described actuator comprises bldc motor assembly, pressure and flow transducer, microprocessor and brushless DC motor driving controller, described bldc motor assembly outfan is connected with the input of described pressure and flow transducer, described pressure is connected with the input of described microprocessor with the outfan of flow transducer, the outfan of described microprocessor is connected with the input of described brushless DC motor driving controller, the outfan of described brushless DC motor driving controller is connected with the input of described bldc motor assembly, described bldc motor assembly passes through hose connection with described filter and nasal mask respectively.
Described microprocessor comprises:
Receiving element: the air flue actual pressure and the flow signal that receive pressure described in air flue and flow transducer feeding;
Comparing unit: be connected with described receiving element, by the treatment pressure ratio of described actual pressure and setting comparatively and calculate difference;
Adjustment unit: be connected with described comparing unit, judge that patient is expiration state or suction condition according to described difference and flow signal, it is expiration state when difference and flow signal all become large, now need to reduce the rotating speed that described brushless DC motor driving controller controls described bldc motor assembly, ensure that the pressure of output squeezing air diminishes, patient expiration's resistance is diminished; Be suction condition when difference and flow signal all diminish, now need to raise the rotating speed that described brushless DC motor driving controller controls described bldc motor assembly, ensure that the pressure of output squeezing air becomes large, help the smooth air-breathing of patient.
During described expiration state, the pressure of output squeezing air is 400 ~ 600bmpa, and during described suction condition, the pressure of output squeezing air is 800bmpa.
Described pressure and flow transducer input are also communicated with the flexible pipe between described bldc motor assembly and nasal mask by flexible pipe.
The two persistent levels positive pressure respirator of one provided by the invention, the treatment pressure ratio adopting air flue actual pressure and setting comparatively and the difference calculated and flow signal judge respiration case jointly, the two all becomes greatly is then expiration state, the two all diminishes is then suction condition, difference and these two parameters of flow signal are adopted to judge that respiration case can guarantee accuracy of judgement, the rotating speed of bldc motor assembly is adjusted again according to judged result, export the compressed air being applicable to pressure, help the smooth air-breathing of patient and expiration; The two persistent levels positive pressure respirator of one provided by the invention, reasonable in design, accurately can judge respiration case and the compressed air of the applicable pressure of adjustment input in time, effectively meet the Treatment need of pulmonary function difference, lung failure, sleep apnea syndrome patient.
