e360
1. The characteristic (Figure ; Outward appearance photograph of e360 : The photograph has a monitor of the outside of the option)
It acts as a lower rank model of e500 from the model number but e360 which is the latest model in the NMI Inc. is the latest model of the sale in 2007. It is quite conscious of Servo i and it has been designed and like a performance, it is a summit level NMI series approximately. After the monitor for whom it is easy to regard as the easy-to-understand operation is smart built, a necessary feature is tight had. The object is an infant with equal to or more than 1-Kg weight-an adult and a wide area. Because it is equipped with the VGA port, the displayed contents of the main unit display can be displayed just as it is with the outside display when connecting a monitor for the PC. It is 4,900,000 yen of price 1 type and a marvelous low price.

3. The explanation of the control circuit, the controlling mechanism
1) The outline of the controlling mechanism
It puts on a sensor by the auto-calibration while operating a resuscitator, it isn't possible not to do it or the big difference of e500 and in e360 is. It got to do the can which is designed, being simple because it saved an auto-calibration feature in e360. A proximal pressure monitor tube was said not to become a problem so much even if there was not it and in e360, it was abolished. Therefore, the susceptibility at the low flow rate was better and the measurement accuracy improved, but the physical strength had anxiety and the hot wire wasn't adopted so far by Fluothane Sir of call feeling . However, it hears that it embarked on the adoption from the long-range results with Evita of the Drager Inc.. By the change of Fluothane Sir of call feeling , an installation site was changed behind the exhalation-valve.
2) The characteristic of the mechanical mechanism
When the airway pressure exceeded from the target value like the BIPAP system of the Drager Inc. in e360, it got to put on a feature, Open Exhalation Valve which misses pressure than the exhalation-valve, in ON/OFF. Biphasic Pressure Release Ventilation(BPRV) became possible with this feature. BPRV is the feature which corresponds to BIPAP, Biphasic, Bi-Level in the place to say in the other company.
3) The gas flow rate measurement
It is a boiling heat ray type with the side of intake and call feeling , too. Fluothane Sir of call feeling can exchange a user because he has a lifetime. Fluothane Sir of call feeling resembles to that in Evita of the Drager Inc. but to that, he has the following reason. The manufacturer who is making consumables toward the specific product as well as the native article exists at any resuscitator in addition to Evita (The aftermarket). It is a 1-company product in it that is used for e3690. Way, the representative of such a product is a patient circuit. Therefore, physically, a sensor for Evita can connect but isn't guaranteed.
4) The intake valve
It is the same as e500.
5) The expiration valve
It is the form which is the same as e500.
4. The new Mattick circuit (Figure ; New Mattick circuit of e360)
1) Intake gas
The control of the control of flow and the blend ratio is done with the flow control valve (the servo valve, Metering Valve) which was independent after decompressed respectively with the regulator about oxygen, the dense fog which was entered than the air plumbing. This valve was one but E-200 became for the peak with high flow rate to have been able to be more supported in being equipped to oxygen and air independent. These gases are the flow transducer of the supersonic transit type which measures a flow rate in the difference of the rate of propagation of the supersonic and are measuring a flow rate. As for this, the propagation time of the sound wave which propagates in fluid is the one to have used the nature that the speed of fluid changes and the difference in the propagation time among two supersonic sending sources becomes the flow rate of fluid.
2) Expiration gas
As for expiration gas, a flow rate is measured by Fluothane Sir of the heat ray type that a heating was done with the heat exchanger after passing an exhalation-valve. After that, it is released in the big worrying. It was attaching Fluothane Sir to e500 in front of the exhalation-valve but e360 has Fluothane Sir behind the exhalation-valve. An exhalation-valve is controlled with the exhalation-valve drive gas which pressure was adjusted to in EXHALATION VSO SOLENOID VALVE. The pressure of this part, too, is monitored.
3) The safety-play
A crossover solenoid is prepared by the purpose of the time to have become one gas and the control gas of the equipment can be secured even if either gas is blocked off. In case of the equipment failure, the relief valve releases and releases a patient circuit in the big worrying. In e500, an airway pressure was monitored at two of call feeling and the proximal pressure but in e360, it is changed into two of the sides of intake and call feeling .
5. The control software
The explanation of the each function
1) The trigger formula
Float rigger (0.1-2.0LPM) and pressure trigger (0.0-5.0cmH2O) can be chosen.
2)A/CMV
As for this, VC, a PC, VTPC are prepared by the active-ventilation by general A/C and the mode to be written. 3)SIMV
It is a variable-time method. As for usual spontaneous-respiration, PSV is added but when choosing VTPC, the spontaneous-respiration becomes VTPS.
4) The cycle OFF(Exp.Threshold)
It was called off a PS cycle in e500, but in e360, it is called cycle OFF(Exp.Threshold) and both of the PS and VTPS are adaptable. This can set the condition to end intake in the PS and VTPS. 5-55%, Auto can be chosen. Basically, it is the same as e500. Auto is called FlexCycle.
5)VTPC/VTPS
It is the same as e500 basically.
6)Flow Wave
"Quantity control" The flow corrugation of the active-ventilation can choose "the dwindling wave", saying "the square wave". The dwindling wave is the corrugation that the intake gas flow rate decreases straight from the peak value to -50% of values.
7)Open Exhalation Valve
While the exhalation-valve of the resuscitator resembles about whether or not it is than about the airway pressure, and is is closed generally at the high pressure (as much as 100-150cmH2O) and the machine recognizes an inspiratory-phase, patient's doing expiration in the summon isn't permitted. On the other hand, the pressure ventilation mode to have applied BIPAP as the development type of BIPAP in Evita of the Drager Inc. was developed (because an exhalation-valve is only closed at the control object pressure) and of what tense however, as for the patient, intake and the expiration became possible freely. Open Exhalation Valve is the function to choose whether or not to do a way of exhalation-valve's closing at the conventional pressure or whether or not to do it by the method like BIPAP. It becomes like BIPAP when making Open Exhalation Valve on. NMI calls this mode Biphasic Pressure Release Ventilation(BPRV).
8) The hill/Rhys
e500 and the same
9) NIV (The mask ventilation)
The availability but pressure ventilation mode's being desirable for a leak revision feature by the inspiratory-phase (like BiPAP of the Respironics Inc.) in all modes because there is not it It is self-adjusting the flow rate of the base flow as the maintenance of the baseline pressure in the expiratory-phase. It calls this leak revision. A base flow is increased to a maximum of 25 LPM. The float rigger isn't stable because the base flow changes in NIV. Therefore, as for the manufacturer, a pressure trigger is being recommended only by NIV.
10) The leak revision
It is the function to do a base flow in the self-regulation to maintain baseline pressure. When making on, it is done in 3-15LPM by the adult and it is done by the self-regulation in the range of 3-8LPM by the infant. When choosing off, the base flow becomes 3LPM fixation.
6. The operation system (Figure ; Operating panel of e360)
1) The basics
The basic operation touches an item for the purpose and chooses an item, and turns a rotary knob and enters value, and in the last, it pushes and it fixes a key "of being fixed". VC can choose from two kinds of setting methods of the intake time and the intake gas flow rate. Of course, at the PC, it becomes an intake adjusts-the-hours.
2) The choice of the mode
There is a key of "the ironhand" and "the quantity control" in the mode. To choose a PC in the active-ventilation, because the indicater changes to A/CMV, SIMV, SPONT in turn when pressing "the ironhand", it chooses a desired mode. To choose VC in the same way in the active-ventilation, it presses and it chooses "the quantity ventilation" from the inside of A/CMV, SIMV, SPONT. To choose VTPC/VTPS, after choosing a mode from either of "the ironhand" "the quantity control", it makes VTPC/VTPS on from the inside of the extension facility of the liquid crystal panel. The one which SPONT has "the ironhand" and "the quantity control" can choose a PC or VC in anaerosis back-up ventilation. When VTPC becomes on, SPONT becomes PTPS. Way, as for VTPC, PRVC, VTPS are the mode to be called VS in Servo i and Servo and so on 300.
3) In case of power start-up
A standby screen is displayed first. (Figure ; Standby screen of e360) The menu of the circuit check, the sensor, the technique, patient setup (Patient Setup), simple setting (Quick Setup) is displayed. Patient setup (Patient Setup), simple setting (Quick Setup), the ventilation setting can be entered when entering and the ventilation can be begun from here. (Figure ; E360 setup-screen) Because setting at the time of power off is preserved last time at the memory, setting in the last time is displayed at the original value. But, only NIV becomes general ventilation. Way, technically, it sets a date, an area, a communication protocol, screen brightness and so on.
7) The simple setup (Quick Setup)
It is possible to set more simply in the ventilation than in the weight entry. It enters a mode and weight. The ventilation starts by the setting which was shown in the table. (Table ; E360 simple setup) (Table ; Alarm setting by e360 simple setup)
4) The proofreading of a sensor
Initial-screen however, the sensor proofreading is possible ventilation operation among them but during ventilation operation, it needs consideration because it becomes the following setting while proofreading. During proofreading of an oxygen concentration measuring function, an oxygen concentration is supplied for 1-3 minutes at 100%. Because 1 second of intake time is necessary to proofread Fluothane Sir of the expiration, during ventilation operation, when the intake adjusts-the-hours is less than 1 second, it is automatically extended by 1 second.
5) The advance setting
In the advance setting, Slope/Rise, Exp.Threshold, Insp.Pause, Flow Wave, Volume Target, Open Exhalation Valve can be set. To summon an advance screen, it touches a key in the lower right of the liquid crystal panel in turn. Because the menu of BASIC, ADVANCED, WEANING, MECHANIC can be in turn displayed, it enters from this place and it sets.
5) Battery drive
It is possible to operate for a maximum of 6 hours by the full charging by built-in battery.
6) The nebulizer
The nebulizer can not be used.
7) The back-up ventilation
The back-up ventilation starts when the alarm of the low expired volume per minute operates. An automatic-removal is done when the expired volume per minute becomes +10%. The setting air changes per hour gets for 1. to be quintuple in A/CMV and SIMV (The within-the-limits of 15-100BPM). In ironhand "NO" SPONT, it is ventilated at ventilating-pressure 15cmH2O+PEEP, the 1.0-second (0.6 seconds of infants) time of intake of air changes per hour 12BPM (infant 20BPM).
7. The monitor, the alarm function
1) The monitor (Figure ; Numeral display screen of e360)
In addition to the general items such as the airway pressure and the expiration expired volume per minute, the various items such as the work volume to the trigger can be monitored.
2) The alarm
It is equipped with the low expired volume per minute, the high expired volume per minute, the low pressure, the high pressure, tachypn ea (OFF,10-150BPM), leak percentage (20-95%), the anaerosis (5-60 seconds) and all necessary items such as the equipment abnormality.
(3) Equipment's being mal-function
8. The display feature
It puts on 2 corrugations of the pressure and the flow with the graphic presentation. The PV curve, the FV curve can be displayed. It is made in the numeral display and the trend display with measurement item and so on. The contents of the main unit display can do a display just as it is at the monitor for the PC because there is VGA output.
9. The patient circuit composition, the humidifier (Figure ; Patient circuit of e360)
The F&P type is come equipped with. The proximal pressure monitor tube to have been using in e500 is unnecessary.
10. The daily maintenance
1) The one of exhalation-valve block : expiration unit of breathing circuit, exhalation-valve ( figure ; e360 ) of a heating is always done and there is not trouble by the dewfall and so on in the whole unit of the expiration of the condition opening a cover..
It exchanges a patient circuit regularly. When attaching an expiration filter, it doesn't need the exchange and the sterilization of the exhalation-valve and Fluothane Sir. It exchanges a filter every regularity and patient. When not using an expiration filter, it does resolution, a wash and sterilization every regularity and patient. When the exhalation-valve of : of way of resolving of exhalation-valve of ( figure ; e360 opens the front-cover of the expiration unit ) of the diaphragm appears when the exhalation-valve of the exhalation-valve can be accessed. removes a cap of it turns a fixed-ring of removing Fluothane Sir cable from the exhalation-valve of it is possible to pull an exhalation-valve out of the main unit it it.. to do it, being counterclockwise when it loosens a latch and it removes it.. When assembling an exhalation-valve, it makes adjust the notch of the exhalation-valve body and the guide pin of the cap and it assembles them. (Figure ; Notch and guide pin of exhalation-valve of e360)

2) Intake Mani fold
To be general doesn't have to be sterilized but when polluting, general can do a resolution wash and sterilization. For the details, it refers to the manual.
3) The way of disinfecting
The exhalation-valve is an autoclave or a gas sterilization. Only expiration Fluothane Sir's gas sterilization
11. The regular inspection
It charges in the internal organ battery every 6 months. The exchange of the specification part every 3,000 hours or year It is the exchange of O'2 senser [ at the 2 or necessity time. It overhauls within 5 or 25,000 hours.
12. The fault
1) That the corrugated graphic display is corrugated in 2 is sorry. 3 corrugations are indispensable.
2) The one by which VTPC/VTPS can be directly set more from the mode panel is more convenient for it.
3) Liquid crystal has a small screen. There be VGA output, too, but become clear if equipped with large-sized liquid crystal from the beginning. If the liquid crystal panel is expensive times, it doesn't anyway find a reason for saving.
4) It is poor in the resolution of the liquid crystal display. It gets the impression which is "SARA" now.
5) That the display contents can not be copied in the digital file is inconvenient. If being, it is easy for there to be for reviewing and a learning meeting later.
6) It is possible to choose only VTPS as the spontaneous-respiration when choosing VTPC. A PS, too, is wished to be made to be able to be chosen by the Advanced setting.
7) Wanting to have a little more investigate Japanese which is used for the menu display It thinks that Japanese "the simple setup" and the meaning of English "Quick Setup" are different. The meaning is unclear about the translation of the open valve, too.
8) The pressure ventilation mode may be open valve on, being average. If saying oppositely, there is not inevitability which makes off at all.
9) Because the flow trigger mechanism doesn't have a leak revision feature, most sensitive 0.1LPM is the possibility that there is not a utility. The pressure trigger, too, can choose 0.0cmH2O in the same way, to choose to the range where there there is not a utility may become, saying "the maximum sensitivity on the value is high", boiling in the layman deceiving but that it is possible choose is irresponsible. The range which can not be recommended as the manufacturer anyway needs the conscience which is made not to be able to be set.
10) Anyhow and it thinks of pressure trigger's being being recommended by NIV. It improves a flow trigger mechanism and the float rigger should make the 1st choice become in all modes. If it is good that a trigger mechanism is made, in all modes, as for the pressure trigger, need is the possibility not to be.
