RTX respirator is the type resuscitator out of the body which is made by the Medivent Inc. in the United Kingdom.
It is the resuscitator which makes the inside of it a positive negative pressure using plastic give light-weight corselet (cuirass) and drives a thorax.
Such a resuscitator is called a cuirass respirator, too.
The type resuscitator out of the body which is represented by the iron lung supplies a body below the neck to the chamber but in the cuirass respirator, it gets handiness and a portability in limiting an driving part to the thoracoabdominal.
Among them, as for RTX respirator, the point which can be the air changes per hour of the high frequency which reaches a maximum of 1200 revolutions per minute, too, and the advanced computer-control and the rich graphic monitor feature are a characteristic.

The battery operating time
It is composed from the pump of the piston-type and Solenoid-controlled valve to release to the atmosphere pressure.
A piston is driven with the linear motor.
For the measurement pressure inside the corselet to become a set-pressure, a motor is driven by the microprocessor control.
1) The connection
It puts a special strap in the back of the patient and it fixes this fast with the corselet.
The patient wears beforehand thin clothing beforehand.
It confirms that it moves a finger according to the corselet exclusive use seal and that there is not a leak.
It connects a main unit and a corselet with the special wide boa tube, the pressure sensor tube.
2) The corselet (cuirass)
11 kinds of corselets are prepared from the newborn baby with 1.8-Kg weight to the equal to or more than 90-Kg adult business.
That the corselet can be appropriately chosen becomes the important element of the success or failure of this artificial breathing.
It chooses a maximum size in the range where there is not a leak.
The corselet must not make touch direct skin.
It becomes a monitor mode behind the self test in 30 seconds when making a power on.
In this mode, it monitors air way pressure, corselet pressure (the cuirass pressure) and SPO2 and in the overseas specification, it monitors ECG.
The machine doesn't help breathing absolutely.
Because the menu of the parameter setting, the mode setting, the alarm setting is displayed in the screen right when pushing MENU key, it moves a cursor using the arrow key, it pushes and it chooses ACCEPT key.
Then, because a menu point according to each setting is displayed, it moves a cursor and it does a necessary choice and an entry.
4) The explanation of the mode
Only the monitor feature works and there is not ventilation operation.
(2) continuous negative
The mode to add a negative pressure continuously It is equivalent
to CPAP in the positive pressure type ventilation law in the
The mode which doesn't synchronize with the spontaneous-respiration
(4) respiratory triggered
It synchronizes with the beginning of intake but the ending of intake is done in time cycle.
It is equivalent to A/C in the positive pressure type ventilation law in the respiratory tract.
The trigger source chooses either of the corselet internal pressure and the airway pressure (detaining a sensing tube in the respiratory tract).
(5) respiratory synchronized
The mode which synchronizes with the beginning of intake, the beginning of the
expiration It is equivalent to PSV in the positive pressure type ventilation
law in the respiratory tract.
(6) secretion clearance
It promotes the emptysis of the phlegm in the mode for the chest-physical-therapy.
It doesn't synchronize with the spontaneous-respiration.
There are vibration and cough.
The former is 240-1200BPM and gives vibration.
It is equivalent to HFV and HFO in the positive pressure type ventilation law in the respiratory tract.
In the latter, it is the mode to copy a cough to the type out of the body.
(7) ECG triggered
It is the mode to make synchronize with the electrocardiogram and to help the ejection of the heart in the ventilation help.
In Japan, this un-approved purpose feature is made a non-way.
The column of the 3rd paragraph is for the ECG display but in the Japanese specification, it is killed from the top of the graphic display to the ECG display feature.
The corselet internal pressure, the inspiratory-pressure, "PURESUTIMOGURAHU" can be displayed with the graphic
display. Incidentally, in the domestic specification, ECG can not be displayed.
It is equipped with the anaerosis (10-30 seconds), the inspiratory-pressure upper limit and the minimum, the expiratory-pressure upper limit and the minimum, the alarm of the pulse oximeter.
6. The patient
7. The maintenance
The wide boa tube at the time every use, the pressure tube, the "WO" check, it exchanges if necessary.
It exchanges corselet fixed (cuirass) in 500 hours by hour.
It does a feature check, a service regularly.
The cleaning, the fuse exchange inside, the check, the wiring check of the bread board test and the pressure transducer of the valve, the check of the screw every 1000 hours or 6 months
It is a battery exchange for the alarm and the exchange of the fan for the cooling in 2000 hours or 1 every year.
It is the checking-adjusting of the valve in 4000 hours or 2 every years.
It is a valve exchange, the exchange of the control module in 16000 hours or 8 every years.
8. The fault
1) There is not a certainty of the ventilation for ability of the ventilation help, too, to be limited. It is halfway for
its purpose. Evaluation isn't established as much as NIV, too.
It is poor in the trigger mechanism and the sensitivity is bad.
Plainly, it isn't possible to catch in case of not being strong breathing.
In the first place, if breathing is strong so much, help something is unnecessary.
The mechanism which takes breathing of the patient surely is wanted.
Because a manner of use and usability aren't established, it is incorporating the feature which has the possibility that it is possible to use.
There is a place of the idea fall.
Therefore, the operating panel is it of the experimental unit and can not do smart practical setting.
There is a feeling that the front of the thorax is continuously beat when attempting to attach actually and there is a uncomfortable feeling.
The chest is hard when attaching long.
At least, for Ken's general human being, breathing can not be called to be easy.
It is ?? to the sick man.
