1. The characteristic (Figure ; Outward appearance photograph of LP10)
However, because LP10 is highly reliable while it is the model which exists from the old days and the maintenance is easy, it is evaluative high as the resuscitator for the movement and the home at present. Originally, it is made by the Aequitron Inc., becoming the one one OBJ DO but which is made from M/A by the Nellcor Puritan Bennett Inc., at present, it is made by the Puritan Bennett Inc. in the Tyco Healthcare group and LP10 is produced as the one. The structure is PLV-100 and companion of the rival machine It is controlling the structure which drives a piston with the electric motor in 2801 and the similarity with MPU. Oxygen can be added by the addition of the option. It is possible for the outside battery in addition to the inner battery to drive. LP6 plus and LP10 are the same almost including the outward appearance, but LP10 is equipped with the pressure pressure relief valve and it is a difference. The home sales is the product of the Tyco Healthcare group, but IMI continues and is doing.
2. The performance
The mode .Pressure cycle, Assist/Control, SIMV
The taking air quantity of ventilation .100-2200ml
The intake time .0.5-5.5 sec. (Flow rate .....20-100LPM)
Breathing number of times .1-38BPM
The battery operating time 1 hour
The weight .15.5 Kg
12 V of power consumption .............................DC, 72-36 The setting changes the W/hr power consumption. 75-80 It operates for about 20 hours with the battery of the outside of amp hrs.
35-40 It operates for about 10 hours with the battery of the outside of amp hrs.
3. The outline of the mechanism (Figure ; New Mattick circuit of LP10)
It drives a piston with the electric motor which is controlled by MPU(Z80A, 4MHz) and it makes intake dense fog occur. Because the pressure pressure relief valve of the mechanical type is preparatory in LP10, surplus "NA"圧 can be missed. An exhalation-valve drive circuit is released by the atmosphere pressure at the normal condition by Solenoid-controlled valve (exhalation solenoid valve), but the intake gas pressure is connected with the time of the mechanical ventilation and closes an exhalation-valve. Gas than the air intake is more directly via two one way valves supplied to the patient circuit side of intake. Because a piston for the mechanical ventilation is connected with this course in parallel, gas with the higher pressure in two pieces of course is supplied to the patient. Even if there is a demand in addition to gas for the spontaneous-respiration by the SIMV mode which exceeds a set value at the time of the mechanical ventilation for its purpose, it becomes applicable with this mechanism. However, the inhalation breathing resistance of the young coming to an end exists that it is possible to say that it is little and for the patient to do intake via the filter and the one way valve from fresh air. A various specification is prepared about the PEEP valve, too, if necessary. The mechanism which adds oxygen to the air intake with the option, too, is prepared. The oxygen concentration can be computed by the oxygen flow rate and the expired volume per minute to add, but it measures an intake oxygen concentration, being final and it fixes it.
4. The operation (Figure ; Operating panel of LP10)
1) The power
It confirms the power to be using. It is had priority over in order which is a AC power, the outside battery, the inner battery. It doesn't depend on the inner battery except the temporary use. At the battery drive time, it checks a battery level timely at the Battery Test button. At this time, the airway pressure meter displays a battery level. Moreover, it reads in the operating time, too, if pushing the button of Battery Test and Alarm Silent/Reset at the same time. Of the mode which is being "DURE" however (including Stand by), if the electric power switch is on if connecting to the electric outlet, it is charging in the battery inside and outside.
2) The check of the equipment
Based on the checklist, every day, it confirms that the patient circuit and the equipment operate.
3) The setting of equipment
It sets breathing mode, a taking air quantity of ventilation, an air changes per hour, intake time, trigger sensitivity, a low pressure alarm, the airway pressure upper limit alarm. When adding oxygen, it measures an oxygen concentration.
5. The alarm
It is equipped with the setting contradiction, the battery voltage, the low airway pressure, the airway pressure upper limit, the equipment failure, the anaerosis, the equal "NO" alarm.
6. The maintenance (Figure ; Patient circuit of LP10)
1) Sterilize a patient circuit and an exhalation-valve every day in the wash if checking them timely and also it does three times, it is possible to do it and the doing of it for every week of minimums. In the period, it depends on the condition and the use environment of the patient.
2) Once in the week at least, at it, when using for the movement, it washes every day the air filter which is in the main unit back.
3) However, it connects to the AC power and it charges beforehand when not using for the battery protection. In the moon, as for the taking, it checks a battery level.
4) In the moon, the taking receive a check by the service. When the thing except the regular service goes, the guarantee and the maintenance can not be received.
