VELA is the successor species of T-Bird and the basic structure is the same as T-Bird.
Operability by the touchpanel and moreover latest breathing mode to contain NIPPV are made the graphic display feature of 3 corrugations which used an electrochromatic display, being fully equipped, being average.
It is the bargain machine of the surprise which has the feature of the fancy machine while being a popularization machine at the inexpensive band.
There are 3 models of Standard, and Plus, Comprehensive in VELA but the differences are few.
It is Plus that added NPPV feature to cheapest Standard and it is Comprehensive that added PRVC, APRV/Bi-Phasic.
As for the price, Standard is 4,200,000 yen, Plus is 4,700,000 yen and Comprehensive is 5,000,000 yen.
The difference is slight because the price difference is a maximum of 800,000 yen but there is a discount in it actually.
The infant-the object patient grows up.
1) The mode that it is possible to use
(+ Only APRV/Biphasic.......Comprehensive model)
2) This proximal dater
The maximum intake gas flow rate
The number of the maximum
The maximum SIMV number of
times .80 BPM
3. The explanation of the control
circuit, the controlling
1) The outline of the controlling mechanism
The microprocessor controls the turn of the turbine and the operation of the exhalation-valve.
2) The characteristic of the mechanical mechanism
Intake gas generator ability by the peculiar turbine is used. A turbine is driven with the fast
response type motor.
3) The gas flow rate measurement
Because the gas flow rate on the side of intake is proportional to the turn of the turbine, if calculating the number that the blade of the turbine was turned, this becomes "TI" intake gas flow rate immediately.
A gas flow rate on the side of the expiration is measured with the delta-pressure type flow transducer of the film type.
4) The intake valve
It doesn't exist. The turbine is
equivalent to this.
5) The expiration valve
It is the film type valve of the servo control type. It is directly
driven with the linear motor.
The low pressure and two high-pressure kinds of the entry by oxygen are possible.
Only when high-pressure, the oxygen concentration setting becomes valid.
The following processing is done about the digital blender.
The necessary oxygen flow rate is the value which hung FiO2 on the intake gas flow rate, but it pours a necessary oxygen flow rate into "MIKISINGUTIYANBA-" in operating the combination of Solenoid-controlled valve of 5LPM, 15LPM and three 40LPM intermittently and is controlling an oxygen concentration.
Because the turn of the turbine becomes intake gas, the complicated processing is necessary for the electric-control type but the mechanism becomes simple.
Because the turbine is Secure HTTP and moreover a living long life, there are few time-change components.
The exhalation-valve is directly driven with the linear motor and the response is good for it.
An expiration gas flow rate is measured with the delta-pressure type sensor.
5. The control
The explanation of the each function
1) The trigger formula
It is a flow trigger formula. It is possible to set in
the range of 1-20LPM.
Ventilation form of quantity ventilation (Volume Breath), pressure ventilation (Pressure Breath), PRVC can be chosen.
In the spontaneous-respiration aspect, PSV can be added. In the active-ventilation aspect, ventilation form
of quantity ventilation (Volume), pressure ventilation (Pressure), PRVC can be chosen.
It is BIPAP in the place to say in the Drager Inc..
It changes two pieces of CPAP pressure alternately.
This synchronizes with the spontaneous-respiration of the patient.
In the trigger window time in case of change, it is possible to set in 0-50% of ranges of the time of high-pressure aspect (Time High), low pressure aspect (Time Low).
Moreover, PSV with optional pressure can be added to both of the high-pressure aspect, the low pressure aspect.
It becomes APRV when setting the time of the low pressure aspect shortly.
PRVC is the ventilation form which does PCV pressure in the self-regulation to become a setting taking air
quantity of ventilation. A pressure change every ventilation is limited below 3pH2O.
The feature only of the Comprehensive model
It is possible to make on only by the pressure ventilation.
It secures the air quantity of ventilation (off, 0.05-2.0 the large, default value off) which was set by the VAPS similarity mode.
As the image, the pressure ventilation and the quantity ventilation begin at the same time.
Because the one where there are these more intake gas flow rates is output, it becomes the gas flow rate of the quantity ventilation when the intake gas flow rate decreases by the pressure ventilation in the early stages of intake.
When an air quantity of ventilation is achieved, the inspiratory-phase ends.
The intake of the pressure ventilation ends when the intake gas flow rate falls to the % value (it is possible to set at 0-30%) to the peak value of the intake gas flow rate in case of pressure ventilation.
In other words, it is possible to make the ventilation of PSV and the similarity when making this on.
It is valid only in PRVC and Vsync. The intake ends when the taking air quantity of ventilation
reaches a set value (0.05-2.5 the large, default value 2.5L).
It is valid only in the quantity ventilation.
It becomes the ventilation mode which is the same as PRVC when making on by the quantity ventilation.
As for the point of difference with PRVC, the setting method of the ventilatory-pattern is different actually only.
PRVC is an independent ventilation mode and sets from the taking air quantity of ventilation, the intake time.
On the other hand, Vsync is an added function to the quantity ventilation.
In the quantity ventilation, it sets a taking air quantity of ventilation and an intake gas flow rate and intake time is more automatically fixed than these values.
The in this way set quantity ventilation shifts to the PRVC ventilation when making Vsync on.
It is valid only with the quantity ventilation.
The standard is the dwindling wave to fall to 50% of intake gas flow rates to the beginning end in the set value of the intake gas flow rate (the intake flow).
The Comprehensive model can choose a square wave.
But, there seems not to be a merit which can choose a square wave.
It is valid only in the quantity ventilation. When making on, as for either in ventilation with 100 times or
7 minutes, in the shorter interval, the quintuple taking air quantity of ventilation of 1. is given.
12) The nebulizer
Nebulizer gas comes out with the oxygen of 6LPM only among the inspiratory-phases when making a nebulizer on.
Therefore, the taking air quantity of ventilation increases that the nebulizer is occupied by 100 ml to the intake time of 1 second.
Also, only the part increases in the oxygen concentration, too.
The nebulizer can be set by the unit in 5 minutes until a maximum of 60 minutes.
13) The battery
In case of the power failure, with built-in battery, it is possible to operate for approximately 6 hours.
14) The dater output
The nurse call, the optical fiber output, printer (HP940C), Video Output (256 color, 800x600, the SVGA monitor) can be output.
1) The basics
Avea and VELA have a common operation system. Operation Menu screen and
so on refer to the clause of Avea.
It sets using the button and the touchpanel display in the operating panel right.
It chooses an item in the touchpanel, and a value entry turns and enters a dial and is fixed in ACCEPT (the understanding).
2) The environment operating
It becomes the screen which chooses first RESUME (resuming by the setting in the last time) or NEW PATIENT (new ³).
It becomes the screen which chooses a humidifier next when choosing and ACCEPTing (the understanding) either.
It chooses HME or a heating humidifier.
Next, it chooses a mode.
Because the item which it should set according to the mode is displayed, it inputs value to them.
The setup button for the anaerosis back-up appears only when choosing APRV/BiPasic, CPAP/PSV, NIPPV/CPAP PSV.
It enters the value which needs this, too.
If the more advanced setting is necessary, it presses the ADV SETTING button which is in the lower right of the touchpanel.
Machine Volume, Flow Cycle, Volume Limit, Vsync, Wave Form, Sigh, Bias Flow, PSV Cycle, PSV Tmax, Time High, Time Low, "NADOWO" can be set.
7. The monitor, the alarm
1) The monitor feature
The air quantity of ventilation, gas flow rate, airway pressure graphic of 3 corrugations can be monitored.
The inspiratory-phase is red and an expiratory-phase is displayed in the blue.
The scale can be chosen in the touchpanel.
The Comprehensive model can measure LOOP, TRENDS, Maximum Inspiratory Pressure, Negative Inspiratory Force, AutoPEEP, a static-compliance and so on.
2) The alarm
The item of High Rate (the air changes per hour excess), Low Ve (the low taking air quantity of ventilation), Low PIP (the airway pressure minimum), High PIP (the airway pressure upper limit), Apnea (the anaerosis time) can be set.
It sets using the touchpanel and the dial.
8. The display feature
It is possible to display in the large-sized electrochromatic display
touchpanel. As for the screen example, it refers to the clause of Avea.
The F&P type is come equipped with.
10. The daily maintenance
1) The daily life
It washes regularly in the resolution according to the protocol which could specify breathing circuit, an exhalation-valve, expiration Fluothane Sir and so on at the patient hospital and it is sterilized.
It assembles an exhalation-valve by the procedure which was shown in the figure.
Don't make a mistake in the both sides of the diaphragm.
Fluothane Sir connects for the tube for the delta-pressure measurement to become looking up.
It isn't possible to measure right when making declining.
Because a tube for the delta-pressure measurement is made short at Fluothane Sir of the improvement type, it becomes the mechanism which can not mis-connect with the distance becoming not enough when not making looking up.
11. The regular
The maintenance fee is very inexpensive when the one with little cost which the check takes is a characteristic about VELA and compares with the other resuscitator.
1) 500 hours
It checks and the cleaning, its exchanging an air intake filter if necessary
2) 5,000 hours
It receives a check by the service. The proofreading of exchange, sensors such as the various filter and the O-ring, a
various operation test, "NADOGA" are done by the case.
12. The fault
1) The solenoid for the oxygen concentration adjustment is still harsh with the ticktick.
2) There may be a worrying person because the noise of the turbine is the very quiet but peculiar sound.
(As for the problem of the noise, there is a peculiar sound in any resuscitator).
3) There is not ONE'S say very much in where such as the performance and the price, the operability, the upkeep. However,
there will be likes and dislikes only in the industrial design of the outward appearance.
4) It should there is necessity which has all feature such as Vsync and Machine Volume which has few differences or investigate.
For example, for there to be PRVC, because Vsync isa ? popularization machine about whether or not it is necessary or of? merely confusing a user only by it, it had better think much of the operability which can use advanced function more easily.
In the meaning to be fully loaded with the feature which equal to or more than 90 percent of consumers can not master, it is the sheet of dried laver of the consumer electronics which is made in Japan almost.
To say so but that only this is fully loaded with the feature at this price (the street price is very inexpensive) are marvelous.
The rival machine is terrible.
Isn't a lot of small-scale manufacturer selected?
5) T-Bird might be smarter about the shape, too, in the integrate type about the exhalation-valve and Fluothane Sir.
6) Because there is noise that the turbine and the exhalation-valve continue to change continuously because the operation of the intake turbine and the exhalation-valve cooperates and the Biphasic mode is done and is "RUNO" mode, it hears only and it bustles.
7) In the pressure ventilation mode except the Biphasic mode, the exhalation-valve is closed in case of intake.
It closes at the standard pressure if made and it is desirable that it is possible to relieve more for the airway pressure above the standard pressure than for the exhalation-valve.
However, this may be a too luxurious request.
