Abstract
The present invention proposes a kind of lung ventilator that patient is lost for part respiratory function, including oxygen mask, mainframe box and WINCE industrial control boards.The intensity of its air-flow according to produced by the patient's current autonomous respiration for detecting, and then trigger matched secondary air, and the moment is synchronous with the holding of patient respiratory frequency, patient's autonomous respiration ability that doctor can detect according to lung ventilator carries out real-time parameter regulation, can ensure that patient can be in the matching stream condition of suitable strength always, such that it is able to realize intelligentized control method to the secondary air rhythm and intensity produced by lung ventilator.Present invention mainly solves two problems：One be that solve cannot the current desired optimal secondary air intensity of real-time judge patient, it is to avoid the different degrees of injury of lungs phenomenon that single standard is caused to patient；Two can be to carry out assisted ventilation in strict accordance with the respiratory rate of detected patient, so as to avoid man-machine uncoordinated problem.
Description
Technical field
The present invention proposes a kind of intelligent rehabilitation lung ventilator, belongs to medical equipment technological field.
Background technology
Lung ventilator is a kind of medicine equipment of the most frequently used auxiliary Rehabilitation in clinical medicine, according to mechanical ventilation principle
Develop.China's lung ventilator is started late, and at present, domestic lung ventilator is technically most of to be in using for reference and imitating state
Outer product technology, in terms of service quality, especially in reliability, lags behind developed countries, so country is very heavy
Depending on the innovation and research of lung ventilator technology.Existing lung ventilator can be largely classified into two major classes according to ventilating mode：Stress control leads to
Gas and volume controlled ventilation.
Pressure controlled ventilation pattern is mainly using airway pressure as handoff parameter.Lung ventilator produces air-flow to enter breathing
Road, makes alveolar ectasia, and chest, lung are extended, and pressure is constantly raised in respiratory tract, and after reaching scheduled pressure value, air-flow terminates, and switchs to
Exhale, now intra-airway pressure constantly declines, and reaches a predetermined value, and air-flow occurs again.Its advantage is to reduce PIP, is subtracted
It is few to cause dangerous probability due to airway pressure；Gas distribution uniform, can improve gas exchanges.But its tidal volume can not be protected
Card, is particularly easy to cause patient-ventilator asynchrony problem.
Volume controlled ventilation pattern is main using capacity as handoff parameter.Lung ventilator breathes default tidal volume by people
Lung is sent into road, and it ensures in predetermined pressure limit, and tidal volume is not influenceed by respiratory dynamics and airway resistance change.
Its advantage is can to provide accurate tidal volume according to preset value, does not result in the excessive or very few phenomenon of ventilation, also will not be with
The change of PFT and change.For from combination property and control effect, better than pressure controlled ventilation pattern.
But all there are two total defects in which type of lung ventilator.One is no specific aim, to different
Patient and different pathological states all carry out assisted respiartion with single control parameter, and hypoventilation often so occurs
Or excessive ventilation phenomenon, different degrees of injury of lungs is caused to patient；Another is man-machine uncoordinated phenomenon, patient respiratory frequency
Assisted ventilation frequency from lung ventilator is different, so can bring great pain for patient.
The content of the invention
In order to overcome the above not enough, the present invention proposes a kind of intelligent rehabilitation lung ventilator.
The technical solution adopted for the present invention to solve the technical problems is：
The present invention includes oxygen mask, mainframe box and WINCE industrial control boards.
Described oxygen mask is exactly medical oxygen mask, is connected for the mouth and nose with patient, and lung ventilator is trouble by it
Person carries out assisted ventilation.
Described mainframe box can be divided into Switching Power Supply, source of the gas, sensor, air guide chamber, magnetic valve and information processing mould
Block.Switching Power Supply as transformer, for system provides suitable voltage；Source of the gas provides air-flow for system；Air guide chamber is used for air guide,
For all parts of connection system；Sensor is used for acquisition system air-flow velocity intensity and pressure；Magnetic valve is used as system
The discharge control of interior gas, is core component；Described message processing module includes USB6009 information acquisition cards and amplifies electricity
Road, i.e., be amplified and analog-to-digital conversion process for the signal for collecting sensor, and signal is ultimately delivered to WINCE works
Concentration analyzing and processing is carried out in control plate.
Described WINCE industrial control boards are microcomputer.In the present invention, the Labview by being installed in industrial control board
Software carries out information processing, instruction control and working condition, the displaying of system performance index to system.Simultaneously because industrial control board
Small volume, portability preferably, can to its it is further expansion realize remote control so that doctor to patient monitoring more and
When, convenience.
Current rate of the present invention according to produced by the current autonomous respiration of patient for detecting, and then trigger matched
Secondary air, and the moment is synchronous with the holding of patient respiratory frequency, it is to avoid patient-ventilator asynchrony problem, doctor can be according to lung ventilator
The patient's autonomous respiration ability for detecting carries out real-time parameter regulation, it is ensured that patient can be in suitable strength always
Matching stream condition, such that it is able to realize intelligentized control method to the secondary air rhythm and intensity produced by lung ventilator.
