Puppy-2
1. The characteristic (Figure ; Outward appearance photograph of Puppu-2)
The origin medical department industry utilizes the advantage of the small-scale company and makes product making with the zest with a remarkable personality of "the inventor at the downtown" triumphant. In a sense, it is the product which got a hint in BiPAP of the Respironics Inc. but it admits a unique device everywhere. Because it is possible for built-in to be battery drive, it has an enough performance as the infant business in the adaptable disease being limited as the adult business because there are few maximum intake gas flow rates and there is not a trigger mechanism, but the smallness and the light weight of it.

3. The outline of the mechanism (Figure ; Structure of Puppy-2)
It is a resuscitator with the method which ‘—‹Cs to the time, the patient which set the gas which was pressurized with the compressor (the manufacturer is expressing with the middle of the compressor and the blower). The difference with the equipment of BiPAP "NADO" is in the difference of the maximum intake gas flow rate, the way of missing surplus dense fog, in the controlling mechanism. Because it is little, as the adult business, there are little saying difficulty stickers, power consumption only in the part with utter and the maximal flow of Puppy-2 is best as the movement business. Also, it is different from T-Bird and intake and the expiration don't change the number of rotations of the turbine. Because the number of rotations and the gas output flow rate of the compressor have a constant correlation, it is adjusting the number of rotations of the compressor according to the set value of the intake gas flow rate. In case of intake, (all if not relieving in the pressure) becomes the intake of the patient in the output of the compressor. In case of the expiration, most of the output gases of the compressor are returned to the suction side. This bypass circuit is said not to be contributing to the reduction of the power consumption too much to reduce the consumption of oxygen. The organization fixed control of the inspiratory-pressure is controlling a pressure pressure relief valve and provides PCV of the pressure relieving type. It becomes the ventilation of the ]—Ê type if making the setting of an inspiratory-pressure high sufficiently and the pressure relieving doesn't happen. In case of the expiration, it is in inverse proportion to each resistance value and the output gas of the compressor is made a by-path-valve and an exhalation-valve in the branch. In other words, the gas which is made an exhalation-valve in the branch becomes the continuing current (the base style) which flows through the patient circuit. Therefore, a continuing current is automatically fixed by the set value of the intake gas flow rate. Because the resistance on the side of the patient circuit declines seemingly when the intake effort of the patient exceeds a continuing current, as for the output of the compressor, the distribution quantity changes according to the resistance difference and at the maximum time, all quantity is done in the branch by the patient. In other words, it is possible to assume that the setting intake gas flow rate is a maximum demand style.
Oxygen can be added with the option. This is the principle to dilute oxygen by the jet venturi effect and for the oxygen concentration adjustment mechanism of the Puritan nebulizer to be the same with that.
The change of intake and the expiration is done in 3way solenoid (Solenoid-controlled valve) but the 8-bit CPU of HD64180R1CP8X (Hitachi) is used for the control circuit.

4. The operation (Figure ; Operating panel of Puppy-2)
The product between intake flow rate (LPM) and the intake time (the second) becomes a taking air quantity of ventilation. Because the unit which is displayed at the panel is different, to compute, it divides LPM(Litter/min.) by 60 and it must be changed into LPS(Litter/sec.). In case of volume ventilation, it sets to the minimum value not to relieve the setting of an inspiratory-pressure in the pressure. When ventilating in the pressure relieving, that the taking air quantity of ventilation sets an inspiratory-pressure while it measures with the spa jomer meter because it doesn't become setting quantity is practical. PEEP/CPAP sets with the control while it sees a manometer. In case of CPAP, it sets breathing number of times to 0. When equipped with the oxygen concentration adjustment mechanism of the option, it adjusts an oxygen concentration to the desired-value with the graduation. It controls a necessary oxygen flow rate according to the measurement expired volume per minute.

5. The monitor, the alarm
The manometer can make the monitor of the airway pressure. With the high airway pressure setting dial which is in the back panel, in the high-pressure alarm, it puts on a low inspiratory-pressure in the caution by the setting of the airway pressure decline alarm which is in the panel. These setting is not an absolute value with pressure and the point which is +/- value to the setting inspiratory-pressure needs note.
6. The maintenance
It does a feature check regularly. It charges in built-in battery every 3 months. It does maintenance regularly.
7. The fault
Because there is not a trigger mechanism, it is difficult for the patient that the spontaneous-respiration is sound, to be certain degree of to use.
