Description
Technical field:
The utility model belongs to medical auxiliary apparatus technical field, and in particular to a kind of list level respirator and double levels are exhaled
The adjustable one-way exhausting device of suction machine universal intelligent.
Background technique:
In recent years the more and more patients with neuromuscular disease of clinical definite (Guillain Barre, peripheral nerve disease, weight flesh without
Power etc.), this kind of disease often the course of disease when limit for length, cure difficult, eventually lead to patient respiratory flesh obstacle, paralysis is unable to load breathing
Movement shows the clinical manifestation of respiratory failure, cough inability.Clinical treatment mostly with tracheotomy, exhale by invasive respirator auxiliary
Inhale the support means such as (double loop), sputum drainage, anti-infective.But this kind of patient forces patient because of the support issue of ventilator
It stays in ICU always, in terms of patient's angle: seriously reducing the daily life quality of such patient, increase patient and family members
Economic expenditure, the chance for losing and reuniting with one's family.In terms of hospital's angle: wasting limited medical resource and good doctor
Shield personnel.In face of such predicament, clinical worker wishes to search out a kind of new Respiration assistance mode, using noninvasive ventilator
Instead of invasive respirator, it is used for neuromuscular patient, patient is allow to be detached from ICU, returns family.But noninvasive ventilator is adopted
It is single loop ventilating mode, using noninvasive ventilator, its expiration is patient by mask expiration, but neuromuscular patient is more
Establish tracheotomy, by the tracheal respiration of incision when tracheotomy patients breathe, when patient expiration, exhaled gas is directly from gas
Pipe notch is expelled directly out, and is easy to cause patient respiratory Airway Collapse in this way, causes patient that can not breathe, and there are certain danger.
Chronic Obstructive Pulmonary Disease is the very high disease of China's respiratory system illness rate, about 100,000,000 patient of China.Chronic resistance
Plug property lung disease is a kind of with limited disease of exhaling, and too early sunken close of intrapulmonary small airway cannot be completely by intrapulmonary when leading to expiration
Gas exhalation, causes lung Dynamic overinflation, CO2 retention, respiratory failure etc..The newest domestic and international guide for the treatment of points out nothing at present
Wound ventilator can reduce chronic obstructive acute episode frequency, improve daily life quality, reduce admission rate.At present market without
Creating ventilator, there are some problems, the Patients with Chronic Obstructive Pulmonary Disease of centering severe in the use of Chronic Obstructive Pulmonary Disease
For, since noninvasive ventilator is single loop ventilation, Patients with Chronic Obstructive Pulmonary Disease is using noninvasive ventilator assisted respiartion
When, however it remains too early fall into of intrapulmonary small airway closes the problem of cannot completely breathing out intrapulmonary gas when causing to exhale.
Currently, being single horizontal noninvasive ventilator and double levels respectively there are mainly two types of the noninvasive ventilators clinically used
Noninvasive ventilator, Dan Shuiping noninvasive ventilator are to provide a physiological stress and support epithelium healing, have guaranteed epithelium healing when sleep
Opening, if usually only simple snoring, the patient to feel suffocated, body is without other serious disease such as hearts or lung
Portion, can using single level.Double level respirators are that two different Positive Airway Pressures are provided for patient, work as patient breaths
When provide higher pressure in favor of air-breathing, lower pressure is then provided as the patient exhales, mainly be suitble to lung it is problematic
Patient, such as pulmonary heart disease, chronic obstructive pulmonary disease etc., help patient that carbon dioxide, sucking more oxygen is discharged.But single horizontal nothing
Ventilator price is created in 5 thousand to 1 ten thousand yuan/platform, and the price of double horizontal noninvasive ventilators is in 1.5 ten thousand to 5 ten thousand yuan/platform, although family
Front yard noninvasive ventilator treat the effect of disease it has been recognised that, and the whole nation is being promoted, but fancy price forces many families
Single horizontal noninvasive ventilator can only be bought, and single level respirator clinical use compliance is poor, most of patients does not tolerate, and causes to put
Abandon the chance of noninvasive ventilator treatment disease.
