Description
Technical field
This utility model relates to a kind of medical apparatus, particularly relates to a kind of tee T be connected with nebulizer for noninvasive ventilator.
Background technology
The pulmonary disease of chronic obstructive pulmonary disease (chronicobstructivepulmonarydisease, COPD) to be a kind of with flow limitation be feature, flow limitation is not exclusively reversible, develops in Progressive symmetric erythrokeratodermia.COPD occupies the 4th in the current cause of the death in the whole world, estimates that its M & M will increase further in following many decades.Acute exacerbations in patients with chronic obstructive pulmonary disease (AECOPD) refers to that patient increases the weight of the clinical events for feature with respiratory symptom, its symptom variation degree exceedes daily range of variation, and cause the change of therapeutic scheme, cardinal symptom is tachypnea, often with panting, uncomfortable in chest, cough aggravation, amount of expectoration increase, sputum color and (or) viscosity change etc.The COPD patient quality of life of acute exacerbation is poor, and hospitalizations is more, and dead risk is larger, increases the weight of impairment of pulmonary function, accelerates progression of disease.
During COPD acute exacerbation, due to the reason such as inflammation of bronchus or pulmonary, mucosa or alveolar hyperemia, edema, capillary permeability is made to increase and increase with glandular secretion, simultaneously fibre swing ability reduces, airway secretions is many and exceed Scavenging activity or the airway secretions thickness of fibre swing, when airway secretions thickness, the ability being removed airway secretions by cough is declined, simultaneously, cough repeatedly, easily brings out breathing muscle fatigue.Airway inflammation brings out bronchospasm, airway resistance is increased, increases the weight of respiratory muscle fatigue.In the COPD patient that pulmonary function has been badly damaged, after patient respiratory muscle fatigue, ventilatory function will be damaged further, occur low ventilation, and cause blood carbon dioxide level to raise (respiratory failure), even occur pulmonary encephalopathy, threat to life.Occurring to prevent patient breathing muscle fatigue, avoiding occurring respiratory failure, COPD Acute Exacerbation Period expansion bronchus and effectively removing respiratory tract sputum are the keys for the treatment of.
The administrated method of bronchodilator comprises intravenous administration, oral medication and Neulized inhalation, wherein Neulized inhalation is not only easy but also effective measures, medicine after atomization goes directly focus, local lesion's drug level is high, required dosage is little relative to Formulations for systemic administration, whole body and other organ side effect little, be the respiratory therapy method that respiratory disorder is conventional; The sweep-out method of airway secretions can be divided into: increase the mobility of airway secretions, promote mucomembranous cilium motion, stimulate or bring out cough and auxiliary suction sputum, and the mobility wherein increasing airway secretions is the whether effective prerequisite of additive method.The method increasing airway secretions mobility has the secretion promoting airway mucus body of gland, the humidity improving suction gas and direct past air flue perfusion normal saline, the humidity wherein improving suction gas is method simple, effective, inexpensive at present, and the method improving suction gas humidity is just Neulized inhalation equally.
Atomization is divided into ultrasonic atomizatio and jet atomization, wherein jet atomization comprises oxygen atomization and Compressed air nebulization (clinical is many with oxygen atomization), jet atomization mainly utilizes the driving force of high velocity air that atomized liquid is atomized into fine particles, during oxygen atomization the dyspnea of patient and untoward reaction uncomfortable in chest few; Atomized liquid is atomized as fine particles by the ultrasonic wave acoustic energy that ultrasound atomizer is produced by atomizing piece concussion, the elimination effect of ultrasonic atomizatio gas to airway secretions is good, but patient easily occurs that dyspnea increases the weight of to wait untoward reaction with uncomfortable in chest, should not apply in AECOPD patient.The diluting effect of atomization gas to airway secretions is a continuous print process, if promote the movement of airway secretions between atomization period simultaneously, the airway secretions that mobility increases after atomization can be moved in time, and the elimination effect of airway secretions is better.
But it is limited that the feature of COPD patient is expiratory airflow, after acute exacerbation, expiratory airflow is limited to be increased the weight of, there is high inflation, produce intrinsic positive end expiratory pressure, reduce inspiratory muscles function, during common nebulae inhalation, pressure is lower than intrinsic positive end expiratory pressure, air flue cannot be opened, and causes medicine to be difficult to suck, reduces atomizing effect; Therefore, how efficiently to improve atomizing effect, be still the difficult problem that those skilled in the art need overcome.
