During power supply, these three state can be entered according to the voltage levvl of a sensing across these batteries
Row determines.Although this user can be therefore, it is possible to distinguish the delivery dress with fully charged battery
The delivery apparatus put and there is partially or completely discharge battery, but such a system does not allows
This user determines the battery using this association with any confidence level, and this medical delivery device can
With the time quantum run.It is true that because conventional method uses the voltage of sensing and because of this
A little voltages depend on delivery rate (such as, a kind of flowing of the health care delivery system of association
Speed, wherein this system includes a single channel or multichannel pump), battery temperature,
And the charge/discharge cycle number that this battery has been carried out, so time when different alarm occurs
Can change with the life-span of this battery.Under such conditions, whether meeting is it is impossible to confirm that remain
Electricity allows movement and health care delivery system (such as a, pump and the pump of association of patient
Controller) from ward to the movement in another region of this medical health facility, be such as used for giving
Medical treatment test, when this during this medical health system the battery of association must be used to run.
To this end, battery management system 60(and specifically, controller 66) it is programmed so that one
Individual display provides the visible instruction of this TROB on a display so that this user

And, battery management system 60 can use a kind of method, and the method makes this user with so
A kind of mode uses these batteries so that avoid such behavior: can coerce 56 to one, battery
The TROB being wherein shown to this user cannot rely on the point of a high confidence level.
According to some embodiment of present disclosure, then controller 66 can be programmed to perform one
Method, the method can include following effect, although as explained below, but the method also may be used
To include that other act on.Specifically, controller 66 can be programmed to: determines when this medical treatment
Care delivery system is connected with these one or more batteries, when this health care delivery system is connected
It is connected to during this one or more battery to control at the beginning of this display unit shows one of corresponding TROB
Begin numeral (this TROB according to the conservative of these one or more batteries and this system model into
Row determines), and determine whether that this TROB is in extension and rises to a memory range maximum
A memory range within, this memory range maximum be less than TROB maximum.Controller
66 can also be programmed to: if this TROB is more than this memory range maximum, then according to being somebody's turn to do
The running status of health care delivery system changes this TROB, and if this TROB little
In this memory range maximum, the most do not consider that the running status of this health care delivery system drops
This TROB low.
By modeling according to conservative (specifically about circulating battery (period), put
Electro-temperature and discharge voltage are modelings of conservative) these batteries are discharged,
It is one or more that system 60 can provide in following benefit.Such as, a conservative modeling can
It is supplied to mono-high confidence of TROB with auxiliary.And, by limiting this discharge voltage, when with
When one system 60 allowing battery 56 to be discharged to the point that conventional system is allowed compares, can
To avoid or at least to limit the possible infringement to these batteries.
And, battery management system 60 can also include being connected with controller 66 and with one
Or multiple batteries 56 attachable charging unit 80.Controller 66 can be programmed to further:
Starting this charger when this medical health system is connected to line voltage is these one or more electricity
Charging in pond, and increases for this TROB according to the state that recharges of these one or more batteries
One the first increment or increase to this TROB maximum.
By perform to provide a limited number of discontinuous increase in this TROB charging (or
Recharging, the two term will be interchangeably used at this, unless the context otherwise suggests),
System 60 can provide one or more following benefit.To a limited number of increase of TROB or
Give back and can promote that each stage that a high confidence recharges process with this associates.By providing
The most a limited number of giving back, this system can also limit this user and put for these batteries continuously
Electricity and the ability of charging, because this user will not be able to estimate this TROB accurately, unless
A limited number of discontinuously giving back with system 60 permission.Therefore, this method encourages this use
Person does not uses battery 56 in charge/discharge range of operation, is wherein recharging filling of period generation
Electricity electric current is high.Alternatively, this user is encouraged to keep this health care the most frequently
Delivery system is connected with mains supply.It is true that think when producing with the use modeled by conservative
When the restriction of raw cell discharge voltage combines, the use limiting high electric current can be by cell damage
Reduce a significant amount, such as 75%.
The most so explain health care delivery system 50, battery management system 60,
Their interaction and the operation of battery management system 60, now explanation system 50,60
The structure of illustrative embodiment and being discussed more fully of operation, with reference to Fig. 1 and 2, and also join
Examine Fig. 3 and 4.Specifically, Fig. 3 illustrates a kind of associated for management with system 50
Or the method 150 of the electric discharge of multiple battery 56, and Fig. 4 illustrate a kind of for management one or
The method 250 of the charging of multiple batteries 56.
Along with controller 66 determines that health care delivery system 50 is connected to battery 56, method 150
Start from frame 152.If this TROB is equal to a TROB minima, then controller 66 is right
After frame 154 make one originally determined.According to some embodiment, this TROB minima can
To be zero minutes.According to other embodiments, this TROB minima can be set to one non-
Zero amount.But, making in frame 154 if this determines: at frame 154, this TROB is equal to being somebody's turn to do
TROB minima, then the method advances to frame 158 and 160, and its middle controller 66 starts one
Individual audible alarm 82 with remind this TROB of this user equal to this TROB minima, and
And control display 64 shows that a visible alarm message is to remind this TROB of this user to be equal to
This TROB minima.Controller 66 can according to frame 156 and 158(its can be simultaneously
Carry out rather than with order as demonstrated) (this can set in advance to run a lasting period
Put or determine), such as 10 seconds.After this period, controller 66 can make health care
Delivery system 50 is closed or power-off.
If controller 66 determines on the contrary: at frame 154, this TROB is not equal to this TROB
Little value, controller 66 can carry out one or more determining, wherein this TROB and one or many
Individual scope or threshold value compare.Once controller 66 is made and being determined, controller 66 can be permitted
Permitted the ability that (or restriction) system 50 changes between different running statuses, to cause this TROB
Change, and audible or visible alarm can be caused to be supplied to this user, or even draw
Play system 50 to close or power-off.Although the embodiment of the method shown in Fig. 3 can provide four kinds
This type of scope or threshold value determine, however, it is understood that be not each enforcement according to present disclosure
Example all will include each, and this type of determines.
Such as, if this TROB is more than to (its referred to here as storage of a concrete value scope
Scope) maximum that sets, then controller 66 according to the operation of method 150 by permission system 50
The change of running status to affect this TROB.On this scope (or this threshold value,
On this memory range maximum), method 150 can do other determination, and these determine finger
The character determining shown information or other features of the operation affecting system 50, but cell tube
A running status according to system 50 is changed this TROB by reason system 60.Similarly, exist
Within the scope of this (or under this memory range maximum), method 150 can be done additionally
Determination, these determine the alarm or shown information that appointment provided, but battery management
The running status not considering this health care delivery system is reduced this TROB by system 60.So
And, although the embodiment shown can provide multiple threshold value to determine, but implements according to other
Example can be made a single threshold value on the contrary about this memory range and determine.
According to some embodiment according to system 60 of present disclosure, this TROB has with reference to relevant
Effect battery capacity, anticipated TROB(or PTROB) and the one of this memory range maximum
Individual or multiple equations, with one or more forms, (it is the conservative of battery 56 and system 50
Property modeling product) and be determined.Such as, controller 66 can be programmed to according to following
Equation (equation 1) determines effective battery capacity (with percent) of each second:
CAP=CAP PCF*(1/3600), wherein
CAP is effective battery capacity (exceeding the amount provided needed for this memory range capacity)；And
And
PCF is that active power consumes the factor.
For a full charge of battery, this available capacity is initially set to equal to 100%.Should
It is conservative based on to battery 56 and health care delivery system 50 that active power consumes the factor
Property modeling and determine.Can represent by multiple forms although this active power consumes the factor,
But this factor provides in a tabular form according to some embodiment, for a limited number of delivery
Each in scope determines a different factor.Such as, it is an infusion pump in system 50
In the case of pump controller, following table may be used for a single channel pump:
Alternately, following table may be used for a multi-channel pump:
During preparing this table, this modeling includes the fortune below in relation to battery 56 with system 50
Row it is assumed that wherein power consumption maximization and battery capacity minimizes:
1. suppose a conventional low ambient temperature (15C) so that consuming and maximizing；
2. suppose that a conventional low-running-temperature (38C) to battery is so that capacity minimizes；
3. suppose that a conventional charge/discharge high period (such as, 50-70) is so that capacity
Minimize；
4. suppose the highest flow rate in each scope so that consuming and maximizing；And
5. suppose that the charge/discharge cycle of an off discharge voltage with 11V is so that capacity
Minimize.
Additionally, this modeling supposes: enough battery capacities can be stored with offer system 50 formerly
Operation in during the front period being referred to as memory range.For this period, it is made that other
Assuming so that consuming maximization, these hypothesis include:
The most all passages (wherein having multichannel) run with the highest delivery (flowing) speed；And
And
2. the unit of display 64 runs (be generally assumed to be and run with 10% backlight) with 50% backlight.
Knowledge based on this effective battery capacity (CAP), below electric current TROB can use
Equation (equation 2) is determined:
CTROB=PTROB*CAP+RRM, wherein
CTROB is electric current TROB；
PTROB is according to the delivery rate (such as, flow rate) provided by system 50,
The anticipated TROB obtained from table provided above；
CAP is effective battery capacity；And
RRM is memory range maximum (being 30 minutes in this case).
It is then assumed that controller 66 determines in frame 154: this TROB is not equal to this TROB
Minima (such as, zero minutes), then method 150 can proceed to frame 162, wherein controls
Device 66 determines whether that this TROB has exceeded a first threshold amount.If this TROB exceedes
This first threshold amount, then method 150 is carried out to frame 164, and controller 66 makes display
