Prompt.
Step S5, control process unit 14 control the measurement that blood oxygen measurement unit 11 carries out oxygen content of blood value.
Step S6, control output unit 18 issues the user with the prompt for indicating to be not suitable for measuring the oxygen content of blood, for example, this is carried
Show can be the word of " environment temperature is too low, row temperature raising measure that come in " is shown by display, and/or by loud speaker to
Report the voice etc. of " environment temperature is too low, row temperature raising measure that come in " in family.
Step S7, user can take appropriate measures after knowing above-mentioned prompt, to ensure in the subsequent oxygen content of blood
Measurement in can obtain correct oxygen content of blood value, to improve the accuracy of diagnosing and treating.If for example, environment temperature mistake
When low, then raising environment temperature can be taken, or the measures such as temperature for improving by modes such as heating, activities tested position,
To meet the condition measured needed for oxygen content of blood value.After completing step S7, flow enters step S5.
In practical applications, step S4 can also be omitted, that is, control process unit 14 can also judge ambient temperature value

Ground, control process unit 14 read the time value of timing unit 17, single can be exported by preset time interval controls
Member 18 issues the user with the prompt for indicating that user is reminded to measure body temperature and/or the oxygen content of blood.For example, the prompt can be by aobvious
Show that device shows the word of " your the measurement blood oxygen ", and/or the light etc. by prompting flash lamp to send out.In this way, patient can be made
The measurement of body temperature and/or the oxygen content of blood can be carried out on time, so that it is guaranteed that acquisition body temperature value and/or blood oxygen contain in time and systematically
Magnitude, and then be conducive to improve the accuracy of diagnosing and treating.In practical applications, above-mentioned preset time interval can be with
By setting automatically manually or by control process unit 14, moreover, the length of time interval can freely be set as the case may be
It is fixed.
In the present embodiment, blood oxygen measuring device also has the work(of the situation of change of monitoring body temperature value and/or oxygen content of blood value
Energy.Specifically, control process unit 14 to the adjacent point value of time of measuring twice (that is, n-th and the N+1 times measure body temperature value and/
Or time point value when oxygen content of blood value, wherein N be natural number) corresponding to body temperature value and/or oxygen content of blood value be compared,
If comparison result exceeds preset body temperature difference and/or oxygen content of blood difference, controls output unit 18 and issue the user with expression
The prompt of the variation abnormality of body temperature and/or the oxygen content of blood.For example, the prompt can show that " your body temperature becomes by display
Change abnormal, please pay close attention to " word, by prompting the light that flash lamp is sent out and/or the vibration sent out by vibrator.Actually answering

Step S40, if comparison result, without departing from preset temperature gap, flow enters step S50;If comparison result
Beyond preset temperature gap, then flow enters step S70.
Step S50, control process unit 14 control output unit 18 issue the user with expression allow measure the oxygen content of blood and/
Or the prompt of body temperature;The prompt can be shown " measurement that PLSCONFM carries out the oxygen content of blood and/or body temperature " by display
Word etc..
Step S60, input unit 22 receive mark input by user and confirm the measurement for carrying out the oxygen content of blood and/or body temperature
Operational order, and send it to control process unit 14;Control process unit 14 controls Oximetry according to the operational order
Unit and/or body temperature measurement unit measure.
Step S70, control process unit 14 control output unit 18 and issue the user with the prompts to be measured such as expression, this is carried
Show it can is the word etc. that " please measuring again later " is shown by display.
Step S80, by preset time interval (can setting time interval as the case may be so that device temperature
Value tends to be equal by the heat exchange between blood oxygen measuring device and ambient enviroment within this time with ambient temperature value) it
Afterwards, flow return to step S10, and repeat step S10~S80.
