In the present embodiment, blood oxygen measuring device also comprises input block 22, and it can be arranged on the housing 10, in order to the operational order of the above-mentioned measurement pattern of relevant selection that receives user input, and sends it to controlled processing unit 14; Controlled processing unit 14 is measured according to the corresponding unit of the selected measurement mode control of this operational order.Input block 22 is the control elements such as button, driving lever.
In the present embodiment, blood oxygen measuring device also comprises memory element 15 and timing unit 17, memory element 15 is arranged on the inside of housing 10, in order to store the oxygen content value of being come by 11 transmissions of Oximetry unit, the body temperature value of being come by 12 transmissions of measurement of bldy temperature unit and/or the next ambient temperature value by 13 transmissions of ambient temperature measurement unit.And, controlled processing unit 14 can be controlled Oximetry unit 11, measurement of bldy temperature unit 12 and/or ambient temperature measurement unit 13 and measure, and the Measuring Time point value when from timing unit 17, reading in Oximetry unit 11, measurement of bldy temperature unit 12 and/or ambient temperature measurement unit 13 and measuring, and with this Measuring Time point value and with it corresponding body temperature value, oxygen content value and/or ambient temperature value be sent to memory element 15; 15 pairs of above-mentioned Measuring Time point values of memory element and with it corresponding body temperature value, oxygen content value and/or ambient temperature value store, the so systematically measured body temperature value of stored record and/or oxygen content value and with it corresponding Measuring Time point, so that the user can carry out analysis-by-synthesis and assessment to institute's canned data more easily, thereby improve accuracy and the work efficiency of diagnosis and treatment.
In the present embodiment, blood oxygen measuring device also comprises transmission unit 16, it be used for to receive from the Measuring Time point value of memory element 15 and corresponding body temperature value, oxygen content value and/or ambient temperature value with it, and adopts wired or wireless mode with the Measuring Time point value and body temperature value, oxygen content value and/or the ambient temperature value of correspondence are sent to the exterior terminals such as computer, display with it.By means of transmission unit 16, can make the user can be more easily will be stored in the information transmission in the memory element 15 to outside other-end, thereby be conducive to use the information of different medical device measuring to gather.
In the present embodiment, blood oxygen measuring device also comprises output unit 18, it is used for receiving the next control signal by controlled processing unit 14 transmissions, and send prompting according to this control signal to the user, and output unit 18 comprises image, sound, light and/or vibration to the mode that the user sends prompting, specific implementation is: output unit 18 can comprise display, display is used for adopting the mode of displayed map picture to send prompting to the user, and its shown image can comprise the contents such as literal, chart.And, display can also be used for oxygen content value, the body temperature value of being come by 12 transmissions of measurement of bldy temperature unit and/or the next ambient temperature value by 13 transmissions of ambient temperature measurement unit that reception is come by 11 transmissions of Oximetry unit, and convert oxygen content value, body temperature value and/or ambient temperature value to video signal, and show.In addition, output unit 18 can also comprise the devices such as speaker, vibrator and/or prompting flash lamp, to realize the adopting mode of sound, light and/or vibration to send prompting to the user.
Because in the situation that ambient temperature is lower around, the tested positions such as finger, ear may be shunk because self temperature reduces the blood vessel tip that causes in it, thereby cause the blood flow at this tested position to reduce, if carry out in this case the measurement of oxygen content value, the blood oxygen signal at tested position may appear can't detect, the blood oxygen signal that perhaps detects can't reflect the oxygen content level of whole human body, thereby has reduced the accuracy of diagnosis and treatment.For this reason, can adopt following method to overcome the generation of the problems referred to above.Particularly, as shown in Figure 4, be the FB(flow block) of blood oxygen measuring device among Fig. 3 under the Oximetry pattern.
Step S1 selects the Oximetry pattern.Particularly, input block 22 receives the operational order of the relevant selection Oximetry pattern of user's input, and sends it to controlled processing unit 14.
Step S2, the measures ambient temperature value.Particularly, the ambient temperature value around 13 pairs of housings in ambient temperature measurement unit 10 is measured, and measured ambient temperature value is sent to controlled processing unit 14.
Step S3, controlled processing unit 14 compares ambient temperature value and the ambient temperature threshold value of presetting (that is, the minimum temperature that allows housing 10 environment on every side to reach), if ambient temperature value is lower than the ambient temperature threshold value, then flow process enters step S6; If ambient temperature value is not less than the ambient temperature threshold value, then flow process enters step S4.
Step S4, controlled processing unit 14 control output units 18 can send the suitable prompting of measuring oxygen content of expression to the user.
Step S5, controlled processing unit 14 control Oximetry unit 11 carry out the measurement of oxygen content value.
Step S6, control output unit 18 sends the prompting that expression is not suitable for measuring oxygen content to the user, for example, this prompting can be the literal that shows " ambient temperature is excessively low; row temperature raising measure that come in " by display, and/or report the voice etc. of " ambient temperature is excessively low, row temperature raising measure that come in " to the user by speaker.
Step S7, user can take appropriate measures after knowing above-mentioned prompting, guaranteeing accessing correct oxygen content value in the measurement of follow-up oxygen content, thereby improve the accuracy of diagnosis and treatment.For example, if ambient temperature is crossed when hanging down, then can take to improve ambient temperature, perhaps improve the measures such as temperature at tested position by modes such as heating, activities, to satisfy the required condition of oxygen content value of measuring.After completing steps S7, flow process enters step S5.
In actual applications, also can omit step S4, that is, controlled processing unit 14 also can after judge that ambient temperature value does not exceed the ambient temperature threshold value, be controlled Oximetry unit 13 and be begun to measure automatically.
In the present embodiment, blood oxygen measuring device also has the interval prompting function of take temperature and/or oxygen content.Particularly, controlled processing unit 14 reads the time value of timing unit 17, can send by predefined time interval controls output unit 18 prompting of expression reminding user take temperature and/or oxygen content to the user.For example, this prompting can be the literal that shows " you should measure blood oxygen " by display, and/or by pointing out light that flash lamp sends etc.Like this, can make the patient can carry out the measurement of body temperature and/or oxygen content on time, thereby guarantee in time and systematically to obtain body temperature value and/or oxygen content value, and then be conducive to improve the accuracy of diagnosis and treatment.In actual applications, above-mentioned predefined interval can be by manually or by controlled processing unit 14 automatic settings, and the length of interval is free setting as the case may be.
In the present embodiment, blood oxygen measuring device also has the function of the situation of change of monitoring body temperature value and/or oxygen content value.Particularly, 14 pairs of adjacent twice Measuring Time point values of controlled processing unit (namely, time point value when the N time and the N+1 time take temperature value and/or oxygen content value, wherein N is natural number) corresponding body temperature value and/or oxygen content value compare, if comparative result exceeds default body temperature difference and/or oxygen content difference, then control output unit 18 sends prompting from the variation abnormality of expression body temperature and/or oxygen content to the user.For example, this prompting can be by display show the literal of " your body temperature variation abnormality please be paid close attention to ", the light that sends by the prompting flash lamp and/or the vibration of sending by vibrator.In actual applications, controlled processing unit 14 can read the corresponding body temperature value of adjacent twice Measuring Time point value and/or oxygen content value from memory element 15; Perhaps, can also directly receive by Oximetry unit 11 and/or measurement of bldy temperature unit 12 and send and the N+1 time Measuring Time coming put corresponding oxygen content value and/or body temperature value, and from memory element 15, read the N time Measuring Time and put corresponding oxygen content value and/or body temperature value.

Particularly, as shown in Figure 5, for blood oxygen measuring device among Fig. 3 judges whether the suitable FB(flow block) of measuring according to the device temperature value.
Step S10, the device temperature value of 19 pairs of housing 10 inside of device temperature measuring unit is measured, and sends it to controlled processing unit 14.
Step S20, the ambient temperature value around 13 pairs of housings in ambient temperature measurement unit 10 is measured, and sends it to controlled processing unit 14.
Step S30,14 pairs of device temperature values of controlled processing unit and ambient temperature value compare.
Step S40, if comparative result does not exceed default temperature gap, then flow process enters step S50; If comparative result exceeds default temperature gap, then flow process enters step S70.
Step S50, controlled processing unit 14 control output units 18 send the prompting that expression allows to measure oxygen content and/or body temperature to the user; This prompting can be the literal etc. that shows " measurement of oxygen content and/or body temperature is carried out in PLSCONFM " by display.
Step S60, input block 22 receive the sign affirmation of user's input and carry out the operational order of the measurement of oxygen content and/or body temperature, and send it to controlled processing unit 14; Controlled processing unit 14 is measured according to this operational order control Oximetry unit and/or measurement of bldy temperature unit.
