Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of high-strength negative pressure therapeutic apparatus for pulsation respiratory disease.
Background technology
According to human body respiration physiology:
Pulmonary ventilation is the gas exchange between outside air and alveolar.Gas turnover lung depends on the power promoting gas flowing and the resistance stoping gas flowing.Power must overcome resistance, and pulmonary ventilation just can be carried out.
IA pressure is called intrapulmonic pressure.Gas turnover lung is because the pressure differential of atmospheric pressure and intrapulmonic pressure causes, and the pressure differential of atmospheric pressure and intrapulmonic pressure becomes the direct driving force of pulmonary ventilation.
The resistance of pulmonary ventilation can be divided into elastic resistance and airway resistance.Elastic resistance is by the retraction force of elastance of lung fiber and the impact of alveolar surface tension.Airway resistance is by the impact of gas flow shape, air flue pipe diameter size, air velocity and Pulmonary volume.
What the change studying Patients with Lung aeration resistance was treated respiratory disorder lapses to highly significant.In respiratory, respiratory muscle is called work of breathing for overcoming elastic resistance and non elastic resistance thus realizing pulmonary ventilation institute work.At the forced expiration initial stage, expiratory gas flow is with firmly degree is relevant, but to breathing middle and late stage, expiratory gas flow just depends on the ability that small airway resistance ambient pressure keeps clear, and has nothing to do with firmly degree of exhaling.Lung inside and outside differential pressure during expiration determines the time of pulmonary ventilation and the size of ventilation.
When respiratory system pathology changes:
Respiratory system pathology change be according to gradually many, the fibre function imbalance of mucous secretion amount, flow limitation, lung excessively inflates and the order Progressive symmetric erythrokeratodermia of ventilatory dysfunction develops, major effect and destroy expiration function: 1, inflammation causes that mucous secretion amount increases, viscosity increases, fibre function is caused to be lacked of proper care, air flue endocrine can not smooth and easyly be discharged, cause airway constriction or obstruction, become sputum blocking.2, because airway constriction, pneumatic duct wall thickening and elasticity reduce, cause gas flow conductance to decline, exhalation flow rate declines; The destruction of alveolar wall causes pulmonary elastic recoil to reduce, and causes driving the intrapulmonic pressure of exhaling to decline, and lung external and internal pressure difference reduces, make the capability deteriorates that small airway remains open, lung is emptying to slow down, and small airway is closed in advance, lung is excessively inflated, forms carbon dioxide retention, become airflow obstruction.3, the joint effect of sputum blocking and airflow obstruction, when causing exhaling, lung external and internal pressure difference reduces, when making expiration, gas flow rate is limited and slow down, cause expiratory dyspnea, increase the weight of again sputum blocking and airflow obstruction conversely further, form vicious cycle, finally become ventilatory dysfunction because ventilation reduces, cause human body anoxia.Patient because of exhale and expectoration obstacle be resolved without effective means all the time, so the state of an illness is always while medicine and oxygen inhalation therapy, again and again, protracted course of disease, increase the weight of gradually, cause patient to cough, breathe heavily, suppress, expectorant, abnormal painful, pulmonary function continuous decrease, invalid, case fatality rate remains high, and aerofluxus expectoration difficulties is a world medicine difficult problem all the time.
Analyze known by above-mentioned pathological change: while respiratory resistance increases, if lung external and internal pressure when can not fundamentally comply with and change expiration when treating is poor, namely increase respiratory drive, then all treatment meanss all can produce little effect.

The treatment of respiratory disorder is a system engineering, and pathological change must be breathed cause the rule of ventilatory dysfunction to carry out because complying with treatment according to physiology of respiration, must determine that according to the lung external and internal pressure difference of exhaling the rule of pulmonary ventilation implements treatment, must when pulmonary ventilation resistance increases corresponding increase pulmonary ventilation power, namely under open state, improve lung external and internal pressure difference and long-range vibration conduction, power-assisted aerofluxus expectoration, could reverse patient ventilation's dysfunction and the irreversible medical science final conclusion of Progressive symmetric erythrokeratodermia.
Pulmonary ventilation power must come from two aspects: 1) because atmospheric pressure is constant, only have and oppositely outside lung, continue to increase high-strength negative pressure by high-strength negative pressure therapeutic apparatus for pulsation respiratory disease, lung external and internal pressure could be increased poor when exhaling, reduce intra-airway pressure, thus delay the small airway shut-in time, extend expiratory duration, effectively the small airway in lung inner high voltage district and IA residual gas are discharged to low-pressure area drain outside lung, expiratory gas flow can be improved, intrapulmonic pressure is declined, thus be more conducive to when air-breathing form negative pressure in lung, to increase inspiration capacity; Its science part is, high-strength negative pressure, under the open state in bilateral nostril, can form negative-pressure air-flow short circuit during air-breathing, thus not affect inspiration capacity.High-strength negative pressure guides and expiration speedup, also helps cilium and upwards swings, and advances small airway sputum to accelerate to discharge, dredging air flue.2) high-strength negative pressure therapeutic apparatus for pulsation respiratory disease more science: the synergism only having high-strength negative pressure and pulsation, could realize the long-range conduction of oscillating air flow, and all conducts vibration in the whole process of exhaling and inhale; Pulsative oscillation frequency is with the frequency multiplication frequency of fibre swing, and air flue peeled off by vibration sputum, by high-strength negative pressure and oscillating air flow, accelerates to drive sputum up; Oscillating air flow also can massage air flue tube wall, alleviates airway spasm.The dual function of high-strength negative pressure and pulsation, the timely discharge of can help the disabled gas and sputum, effectively dredges air flue, thoroughly antiinflammatory, improves ventilatory dysfunction and eupnea physiological environment.High-strength negative pressure therapeutic apparatus for pulsation respiratory disease, by the establishment of respiratory drive, effectively improves aerofluxus expectoration ability, could realize lapsing to of respiratory system disease treatment.
