PrincipalG as Flow

2.2

Principal Gas Flow The H A M ILTO N -C 2 regulates the flow of gases at three p oints, as represented in the d iagram in Figure 2 -9. Room air (A ) is aspirated, m ixed w ith com pressed oxygen (C ) from an external high or low pressure sup ply (B) an d com pressed in the Blow er A ssem bly (D ).The flow of the air/oxygen m ixture is reg ulated at three points: • A ir and o xygen m ixture in the Blow er A ssem bly (D - reg ulation point 1). • A ir and oxygen m ixture throu gh the Inspiratory Valve an d Flow Sensor (E - regulation point 2). • Expired gas from the p atient throu gh the Expiratory Valve (F - regulatoin point 3). Expired gases from the p atient are allow ed to escape into the room .

Figure 2-9. Principal Gas Flow

The “PrincipalG as Flow ”is the flow of air and oxygen into the H A M ILTO N -C 2, out to the p atient, and b ack through the H A M ILTO N -C 2 to the room . This flow is m an aged by com ponents that regulate the gases at three p oints: • Ro om air and oxygen into the B low er A ssem bly • G as to the patien t at the Inspiratory Valve • G as from the patien t at the Expiratory Valve Th e follow ing section provides details of the com ponen ts that m an ag e the “Principal G as Flow ”.

Do not immerse the Battery in water or seawater and do not allow it to get wet. Otherwise, the protective features in it can be damaged, it can be charged with extremely high current and voltage, abnormal chemical reactions may occur in it, possibly leading to acid leakage, smoke emission, bursting and/or ignition. 7. Do not pierce the Battery with a nail or other sharp objects, strike it with a hammer, or step on it. Otherwise, the Battery will become damaged and deformed, internal short-circuiting can occur, possibly leading to acid leakage, overheating, smoke emission, bursting and/or ignition. 8. Do not strike or throw the Battery. The impact might cause leakage, overheating, smoke emission, bursting and/or ignition. Also, if the protective feature in it becomes damaged, it could become charged with an extremely high current and voltage, abnormal chemical reactions can occur, which can lead to acid leakage, overheating smoke emission, bursting and/or ignition. 9. Do not disassemble or modify the Battery. The Battery is equipped with built-in safety/protection features. Should these features be disabled, the Battery can leak acid, overheat, emit smoke, burst and/or ignite. 10.If the Battery leaks and the electrolyte gets into the eyes, do not rub them. Instead, rinse the eyes with clean running water and immediately seek medical attention. Otherwise, eye injury may result. 11.Do not use an apparently damaged or deformed Battery. Otherwise, acid leakage, overheating, smoke emission, bursting and/or ignition of the Battery may occur. 12.Do not directly solder the Battery. Otherwise, heat can melt down its insulation, damage its gas release vent or safety features, possibly leading to acid leakage, overheating, smoke emission, bursting and/or ignition. 13.If the Battery leaks or gives off a bad odor, remove it from any exposed flame. Otherwise, the leaking electrolyte may catch fire and the Battery may emit smoke, burst or ignite. 14.If the Battery gives off an odor, generates heat, becomes discolored or deformed, or in any way appears abnormal during use, recharging or storage, immediately remove it from the equipment or Battery Charger and stop using it. Otherwise, the problematic Battery can develop acid leakage, overheating, smoke emission, bursting and/or ignition. 15.Do not reverse the positive (+) and negative (-) terminals. Otherwise, during recharging, the Battery will be reverse-charged, abnormal chemical reactions then may occur, or excessively high current can flow during discharging, leading to acid leakage, overheating, smoke emission, bursting and/or ignition. 16.The positive (+) and negative (-) terminals are arranged in a particular orientation. Do not force

Rechargeable Lithium Ion Battery The R echargeable Lithium Ion Batteries utilized in the H A M ILTO N -C 2 are m anufactured by M oltech Pow er System s. The Backup Battery provides backup po w er to the H A M ILTO N -C 2. Note • The B acku p Battery is intended for short-term use o nly.It is not intended to be a prim ary pow er source. • H A M ILTO N M ED IC A L recom m ends that the Ventilator’ s Batteries be fully charged before you ventilate a p atien t. If the Batteries are not fully charged an d the A C pow er fails,alw ays pay close atten tion to the level of Battery C harge.

8.2.1

Introduction Tw o Backup Batteries,one standard and the other optional, protect the H A M ILTO N -C 2 from low , or failure of, the prim ary po w er source. W hen the prim ary po w er source (either A C M ains Pow er or a D C Po w er Supply) fails,the ventilator autom atically sw itches to Backup Battery operation w ith no interruption in ven tilation. A n alarm sou nds to signal the sw itchover. You m ust silen ce the alarm to confirm notification of the p ow er system chan ge; this resets the alarm . If the optional Battery (Battery 2) is availab le an d ad eq uately ch arged , the ven tilator sw itches to this Battery first. W hen Battery 2 is dep leted or not installed , the ven tilator sw itches to the stan dard Battery (Battery 1). Th e Batteries pow er the ven tilator untilthe prim ary pow er source is again ad eq uate or untilthe Battery is depleted. Each Battery pow ers the ventilator typically for 2.5 hours or a m inim um of 2 hours.

The u ser has the option to calibrate the fuelgauge and charge the Battery, or to only charge the Battery. Th is option is given becau se a recalibration cycle is longer than a charge cycle. To recalibrate the Battery, press the calibrate b utton on the front of the charger. Note N o action is req uired if only a recharge is required , as the ch arger w illau tom atically beg in to charge the battery.

Recalibration Description The FuelG auge in the Battery uses a highly accurate voltm eter, am m eter and tim e clock to m easure actualcharge in an d out of the B attery. In ad dition, there are algorithm s to com pen sate for the effects of discharge rate, discharge tem perature, self-discharge an d charging efficien cy etc. A llthis com bines to provide a highly accurate Fuel G au ging System . W hat is also req uired is the m eans to ensure the co ntinued reliab ility of this system throughout the life of the Battery. Even w ith allthis technology, the only tim e at w hich the Battery is ab solutely certain of its real cap acity is w hen it is either com pletely fullor com pletely em pty. A nyw here in betw een is a calculated estim ate - albeit a highly accurate calculated estim ate. A lso, as the Battery ages, the am ount of availab le capacity shrinks - so each cycle the "full" point gets a little bit low er. W hat's m ore, if the B attery only sees partial charges and discharges during its application, then it m ay not get the benefit of a "full" or "em pty" reference point for som e tim e an d m ust rely m ore and m ore on its calculated figure. The Fuel G auging System m ay be sub ject to drift during use.

In use, as the Fuel G au ge m athem atically w orks out the Batteries rem aining cap acity. It w illalso w ork out an estim ated accuracy figure kn ow n as the "M ax Error". This keeps track o f the overall accu racy of the system . In this w ay,the B attery can tellthe d evice not only how m uch cap acity is rem aining,but also how reliable this estim ate is. W hen a M oltech Pow er System s or Inspired Energy battery achieves a m ax. error of 10% the recalibration bit is set. So m e d evices use this recalibration bit to trigger a note o n the d evice screen to tellthe u ser to recalibrate their Battery. Th e Battery C harger/C alibrator uses the recalibration bit to tellthe user if recalibration is necessary and flashes the red LED if the B attery FuelG auge is becom ing inaccurate. Th e recalibration is used to re-set the Fu el G au ge algorithm s,re-estab lish the fullan d em pty points, an d re-calculate the actual capacity in the B attery. In this w ay, even as the B attery ages an d things chan ge, the accuracy and reliab ility of the Fuel G au ge can be retained throughout the life o f the Battery. In order to carry out a fullrecalibration the follow ing m ust occur: • Either;beg in w ith a fully discharged Battery, or discharge aw ay an y residual cap acity. • Fully charge the Battery (this tells the system how m uch charge h as been put into the b attery to take it from 0% to 100% charged, and establishes the current "Full" point.) • Fully discharge the Battery (Th is tells the system how m uch of the fullcharge input is availab le for discharging, an d re-sets the M ax Error) A t this point the Battery is calibrated, but it is also em pty - so itneed s a fullrech arge to return it to use.
