Reference explanation example 1 is explained further details in the present invention, and wherein example 1 illustrates heretofore described special The concrete use case of the equipment 100 of configuration.
Example 1：
Referring to the Fig. 5 provided for purpose of explanation flow chart, neonate can deliver to (block 502) equipment 100, described to set Standby 100 by that can have the offer of baby's warmer of the general type shown in Fig. 3.One or more skin temperature probes (probe) (block 506) can be placed on baby to monitor its skin temperature.Optionally, for example, for specific health shape The baby of condition, the default value (in block 510 an) that operator nursing staff can be changed in advanced setting, i.e. (a) blood volume, (b) blood circulation rate, (c) tidal volume, (d) respiratory rate, (e) hospital height above sea level (atmospheric pressure).These values can by touch-screen or Keypad or the other users interface arrangement 226 of equipment 100 are modified.The value of these operators input can include passing through The sensor values that one data or multiple programs 280 are inputted and obtained as sensor.The value of these operators input may include The one or more characterization values in addition to sensor values that can be obtained by one or more programs 280, as one or more It is individual to characterize input.While data input in block 514, one or more sensors 228 of equipment 100 can start to provide Data, to be obtained by one or more programs 280, inputted as one or more.
Next, operator nursing staff's (block 518) can key in the characterization information on baby, example into equipment 100 Such as, (i) height, (ii) gestational age, (iii) age in postpartum, described information can be obtained by equipment 100, be inputted as characterizing.Operator Nursing staff can also input the nearest DIE Temperature measured value obtained from DIE Temperature sensor.After operator's (block 522) Can be by clicking key to run warmer.For the exemplary user interface screen for the equipment 100 for inputting and/or presenting data Curtain display 260 is described by reference to Fig. 6-8 in the present invention.
