Description
Technical field
This utility model relates to a kind of oxygen breathing apparatus, is specifically related to the MEMS hot type of a kind of band flow-control
Oxygen breathing apparatus.
Background technology
In prior art, oxygen breathing apparatus is to be connected to need defeated by oxygen catheter by the oxygen in oxygen tank
The nasal cavity of the patient of oxygen, and the pressure in different oxygen tanks is different, is therefore delivered to the nasal cavity of patient
The flow of oxygen also differ, usual oxygen tank uses the initial stage, and the oxygen flow in oxygen catheter is excessive, super
Cross the oxygen uptake demand of patient, thus cause waste, and oxygen is typically to flow to patient, only people always
Close for ground, usually can bring to patient and cure by oxygen therapy the harm such as oxygen-intoxication caused for a long time, and this harm
Being not easy to time slight find, this is totally unfavorable for the treatment of patient.
Utility model content
Main purpose of the present utility model is to provide the MEMS hot type oxygen breathing apparatus of a kind of band flow-control.
For achieving the above object, the technical solution adopted in the utility model is: the MEMS of a kind of band flow-control
Hot type oxygen breathing apparatus, including oxygen catheter, described oxygen catheter arranges the control valve that can close oxygen stream,
Described control valve connecting valve controller, valve positioner electrical connection MEMS thermal sensor, described MEMS
Thermal sensor is arranged on oxygen catheter inwall, and MEMS thermal sensor connects display；
That is it is provided with control valve on oxygen catheter, oxygen catheter can be opened and close, and can
With the aperture of control valve, and control valve is to be controlled by valve positioner, and valve positioner is according to setting
Put the flow signal that the MEMS thermal sensor at oxygen catheter inwall passes back and control valve implemented open and close controlling:
Specially preset flow upper lower limit value, when the flow value that MEMS thermal sensor is passed back is more than higher limit
Then the aperture of control valve is turned down, then will control when the flow value that MEMS thermal sensor is passed back is more than higher limit
The aperture of valve processed tunes up.The most i.e. can guarantee that oxygen flow keeps within the specific limits, it is to avoid its flow is excessive
Or it is too small.MEMS thermal sensor connects display simultaneously, and its data on flows shows over the display.
Described oxygen catheter measurement part is divided into three sections: air inlet section, measuring section, air outlet section, described oxygen catheter
Three sections in caliber identical, described measuring section is straight pipe, and described air inlet section and air outlet section are conical pipe, two
One end that section is connected with measuring section is than the thickness of pipe wall of former oxygen catheter；
Being provided with at the oxygen catheter of MEMS thermal sensor is measuring section, and oxygen enters one end of measuring section for entering
Gas section, oxygen flow out measuring section one end be air outlet section, this bore of three sections is identical, but air inlet section and
The tube wall thickness of pipe wall than former oxygen catheter connecting end of air outlet section and measuring section, namely the tube wall of junction is
Progressive additive, the tube wall of certain measuring section is also that thickening processes, and the purpose of do so is defeated in order to improve
The intensity of oxygen pipe measuring point, it is to avoid the loss of strength brought because increasing valve and sensor, extends oxygen therapy
The service life of device.
Between described MEMS thermal sensor and control valve, the distance along oxygen catheter is 5-10cm.That is
Being arranged at by sensor on the oxygen catheter inwall after control valve 5-10cm, the purpose of do so is to subtract
Little cause the most smart of flow owing to the obstruct of control valve makes oxygen flow out the phenomenons such as existing unstable whirlpool
Really.
MEMS i.e. microelectromechanical systems, thermal type flow measuring is to utilize heat transfer theory, i.e. fluid in flowing
And heat exchange relationship measures flow between thermal source (in fluid, additional hot body is managed in object or the measurement of heating)
Technology.The advantages such as MEMS thermal sensor has highly sensitive, and corresponding speed is fast.Select this sensor herein
Oxygen flow in oxygen catheter is monitored, preferably oxygen flow can be measured accurately and control.
Further, arrange bottom the measuring section of described oxygen catheter groove direction be perpendicular to caliber to groove, institute
The bottom surface stating groove is plane, and the width of groove is identical with measuring section length.That is the measurement of oxygen catheter
Arranging the groove that bottom surface is plane bottom Duan, the width of groove is identical with the length of measuring section, and groove direction with
Caliber is vertical, when measuring this groove can be stuck in the table of level along or strut on to ensure measuring section
Level, thus improve the accuracy of measurement result further.
Further, described valve positioner is arranged can the button of open and close control valve, described valve positioner
Inside also setting up intervalometer, described intervalometer connects display.It is to say, valve positioner can be by pressing
The operation of key is turned on or off, and valve positioner is controlled also by intervalometer, can set
Curing by oxygen therapy interval time, the time signal of intervalometer shows over the display, so for operator
More directly perceived simple.
Oxygen flow can be carried out by the MEMS hot type oxygen breathing apparatus of this utility model a kind of band flow-control
Accurately measure, and flow can be controlled, substantially increase the safety of patient's oxygen therapy.
