AccuChek Combo pagrindinio naudojimo patarimai

NOTE: Starting with AAPS version 3.2, a new Combo driver (referred to as „combov2“ sometimes) has been added. The old driver is also referred to as the „Ruffy-based driver“. Some parts of this document only apply to the old driver. These will be annotated accordingly.

Kaip užtikrinti sklandų veikimą

  • Always carry the smartphone with you, leave it next to your bed at night. As your pump may lay behind or under you body while you sleep, a higher position (on a shelf or board) works best.

  • Always make sure that the pump battery is as full as possible. See the battery section for tipps regarding the battery.

  • (Only applies to the old driver) It is best to not touch the app ruffy while the system is running. If the app is started again, the connection to the pump can break off. Once the pump is connected to ruffy, there is no need to re-connect. Even after a restart of the phone, the connection is automatically re-established. If possible, move the app to an unused screen or in a folder on your smartphone so you do not accidentally open it.

  • (Only applies to the old driver) If you unintentionally open the app ruffy during looping, it’s best to restart the smartphone right away.

  • Whenever possible, only operate the pump via the AAPS app. To facilitate this, activate the key lock on the pump under PUMP SETTINGS / KEY LOCK / ON. Pompos mygtukus reikia naudoti tik tada, kai keičiamos pompos baterijos arba rezervuaras.


Pompa nepasiekiama. Ką daryti?

Aktyvuoti Pompa Nepasiekiama aliarmą

  • In AAPS, go to Settings / Local Alarms and activate alarm when pump is unreachable and set pump not reachable limit [Min] to 31 minutes.

  • Tai duos jums pakankamai laiko, kad aliarmas nenuskambėtų, kai jūs paliekate kambarį palikę telefoną ant stalo, bet informuos jus, jei pompa negali būti pasiekta laiko tarpą, viršijantį laikinos bazės dydžio laikotarpį.

Atstatyti pompos pasiekiamumą

  • When AAPS reports a pump unreachable alarm, first release the keylock and press any key on the pump (e.g. „down“ button). As soon as the pump display has turned off, press Refresh on the Combo Tab in AAPS. Dažniausiai tada ryšys vėl veikia.

  • If that does not help, reboot your smartphone. After the restart, AAPS will be reactivated and a new connection will be established with the pump. If you are using the old driver, ruffy will be reactivated as well.

  • The tests with different smartphones have shown that certain smartphones trigger the „pump unreachable“ error more often than others. AAPS Phones lists successfully tested smartphones.

Pagrindinės dažnų komunikacijos klaidų priežastys ir pasekmės

  • On phones with low memory (or aggressive power-saving settings), AAPS is often shut down. Apie tai galite spręsti, jei Bolus ir Skaičiuoklės mygtukai pagrindiniame ekrane nėra rodomi atidarius AAPS, nes sistema inicijuojama. Tai gali iššaukti „pompa nepasiekiama aliarmus“ startuojant. In the Last Connection field of the Combo tab, you can check when AAPS last communicated with the pump.

Pump unreachable

No connection to pump (as shown in the old driver's tab)

No connection to pump (as shown in the new driver's tab)

  • Ši klaida gali greičiau sekinti pompos bateriją, nes bazės profilis yra nuskaitomas iš pompos, kai programėlė startuojama iš naujo.

  • Tai taip pat padidina klaidos galimybę, kuri lemia, kad pompa atmeta visus ateinančius prisijungimus kol nepaspaudžiamas mygtukas ant pompos.

Neveikia laikinos bazės dydžio atšaukimas

  • Occasionally, AAPS can not automatically cancel a TBR CANCELED alert. Then you have to either press UPDATE in the AAPS Combo tab or the alarm on the pump will need to be confirmed.

Pompos baterijos naudojimas

Baterijos keitimas

  • Po senka baterija aliarmo, baterija turėtų būti pakeista kaip įmanoma greičiau, kad energijos užtektų užtikrinti patikimam Bluetooth ryšiui su telefonu, net jei telefonas yra toliau nuo pompos.

  • Net ir po aliarmo senka baterija baterija gali būti naudojama dar nemažai laiko. Tačiau rekomenduojama visada su savim turėti naują bateriją po nuskambėjusio „senka baterija“ aliarmo.

  • Before changing the battery, press on the Loop symbol on the main screen and select Suspend loop for 1h.

  • Wait for the pump to communicate with the pump and the bluetooth logo on the pump has faded.

Bluetooth enabled

  • Release the key lock on the pump, put the pump into stop mode, confirm a possibly canceled temporary basal rate, and change the battery quickly.

  • When using the old driver, if the clock on the pump did not survive the battery chenge, re-set the date and time on the pump to exactly the date/time on your phone running AAPS. (The new driver automatically updates the pump’s date and time.)

  • Then put the pump back in run mode select Resume when pressing on the Suspended Loop icon on the main screen.

  • AAPS will re-set a necessary temporary basal rate with the arrival of the next blood sugar value.

Baterijų tipai ir galimos trumpo baterijų tarnavimo laiko priežastys

  • As intensive Bluetooth communication consumes a lot of energy, only use high-quality batteries like Energizer Ultimate Lithium, the „power one“s from the „large“ Accu-Chek service pack, or if you are going for a rechargeable battery, use Eneloop batteries.

Energizer OnePower

Ranges for typical life time of the different battery types are as follows:

  • Energizer Ultimate Lithium: nuo 4 iki 7 savaičių

  • Power One Alkaline (Varta) iš paslaugų paketo: nuo 2 iki 4 savaičių

  • Eneloop rechargeable batteries (BK-3MCCE): 1 to 3 weeks

If your battery life is significantly shorter than the ranges given above, please check the following possible causes:

  • (Only applies to the old driver) Versions of the ruffy App after vMarch 2018 significantly improved pump battery lifetime. Make sure you are on the newest version if you have issues with a short battery lifetime.

  • Yra keli variantai užsukamų Combo pompos baterijų dangtelių, kurie dalinai užtrumpina baterijas ir jas greičiau iškrauna. Dangteliai be šių problemų gali būti atpažįstami iš aukso spalvos metalinių kontaktų.

  • Jei pompos laikrodis „neišgyvena“ greito baterijos pakeitimo, greičiausiai sugedo kondensatorius, kuris palaiko laikrodžio veikimą trumpai sutrikus energijos tiekimui. In this case, a replacement of the pump by Roche might help, which is not a problem during the warranty period.

  • Išmanaus telefono įranga ir programos (Android valdomos sistemos ir bluetooth susijungimas) taip pat įtakoja pompos baterijos tarnavimo laiką, net jei konkretūs faktoriai dar ne iki galo žinomi. Jei turite galimybę, išbandykite kitą telefoną ir palyginkite baterijos tarnavimo laiką.

Laiko persukimas

NOTE: The new driver automatically sets date and time and handles daylight saving time changes on its own. The steps below all only apply to the old driver.

  • Kol kas combo draiveriai nepalaiko automatinio pompos laiko nustatymo.

  • Tą naktį, kai persukamas laikas, laikas telefone yra atnaujinamas, bet laikas pompoje lieka nepakeistas. Tai lemia aliarmą dėl skirtingo laiko tarp sistemų 3 val. ryto.

  • If you do not want to be awakened at night, deactivate the automatic daylight saving time changeover on the mobile phone in the evening before the time changeover and adjust the times manually the next morning. A good way to deal with daylight saving time changes is to switch to a different time zone located on the same longitude you are located at but closer to the equator, where usually no daylight saving time is observed. Example: For Central Europe on Summer Time (CEST/GMT+2), you could switch to the time zone of Zimbabwe on your phone the night before the switch to winter time and then switch back to Central European Time CET/GMT+1 the next morning while changing the clock on your pump at the same time. The other way aroud, switch to the time zone of Nigeria while on Winter Time CET/GMT+1 and go back to Central European Summer Time (CEST/GMT+2) the morning after the switch to summer time and change the pump time accordingly. Look at to find a suitable country.

Ištęstas bolusas, daugiabangis bolusas

The OpenAPS algorithm does not support a parallel extended bolus or multiwave bolus. But a similar treatment can be achieved by the following alternatives:

  • Use e-Carbs when entering carbs or using the Calculator by entering the carbs of the full meal and the duration you expect the carbs to arrive as glucose in you blood. The system will then calculate small carbs equally distributed over the whole duration which will cause th algorithm to provide equivalent insulin dosing while still permanently checking the overall rise/decrease of the blood glucose level. For a multiwave bolus approach, you can also combine a smaller immeadiate bolus with e-carbs.

  • Before eating, on the Actions tab in AAPS set as a temporary Eating Soon goal with target glucose 80 for several hours. The duration should be based on the interval you would chosse for an extended bolus. This will keep your target lower than usual and therefore increase the amout of insulin delivered.

  • Then use the CALCULATOR to enter the full carbs of the meal, but do not directly apply the values suggested by the bolus calculator. If a multiwave-like bolus is to be delivered, correct the insulin dosage down. Depending on the meal, the algorithm now has to deliver additional SMBs or higher temporary basal rates to counteract the increase in blood sugar. Here, the safety limitation of the basal rate (Max IE / h, Maximum basal IOB) should be very carefully experimented with and, if necessary, temporarily changed.

  • If you are tempted to just use the extended or multiwave bolus directly on the pump, AAPS will penalize you with disabling the closed loop for the next six hours to ensure that no excess insulin dosage is calculated.

Disabled loop after multiwave bolus

Aliarmai leidžiant bolusą

  • If AAPS detects that an identical bolus has been successfully delivered at the same minute, bolus delivery will be prevented with identical numer of insulin units. If your really want to bolus the same inuslin twice in short succession, just wait two more minutes and then deliver the bolus again. If the fist bolus has been interruped or was not delivered for other reasons, you can immediately re-submit the bolus since AAPS 2.0.

  • The alarm is a safety mechanism that reads the pump’s bolus history before submitting a new bolus to correctly calculate insulin on board (IOB), even when a bolus is delivered directly from the pump. Turi būti užkirstas kelias nepastebimiems veiksmams.

Double bolus

  • Šis mechanizmas taip pat atsakingas už antrą klaidos priežastį: Jei naudojant boluso skaičiuoklę kitas bolusas yra leidžiamas su pompa ir dėl to pasikeičia bolusų istorija, bolsuo skaičiuoklės pagrindas yra neteisingas ir bolusas yra atšaukiamas.
