Description

血氧计及其工作方法 Oximeter and its working methods

技术领域 FIELD

[0001] 本发明关于医疗检测设备,特别关于血氧计,具体地讲关于一种血氧计及其工作方法。 [0001] The present invention relates to a medical detecting device, in particular on the oximeter, the oximeter particular one kind on its working methods.

背景技术 Background technique

[0002] 血氧计作为一种常用的医疗检测设备,用于对人体血氧饱和度和脉率等的测量。 [0002] oximeter commonly used as a medical detecting device for the measurement of blood oxygen saturation and pulse rate and the like.

[0003] 目前的血氧计主要包括监护仪,如医院的ICU、CCU等监护病房使用的监护仪。 [0003] The current oximeter including monitors, such as the hospital's ICU, CCU and other care unit use the monitor. 患者的血氧饱和度和脉率经传感器接收后,通过导线传输给监护仪,该监护仪收到数据后进行实时显示、储存、分析等。 Patients pulse rate and oxygen saturation sensor, after receiving the monitor to be transmitted via the monitor wire, after receiving the data real-time display, storage and analysis. 专利号为ZL97196522.6的发明专利申请公开一种数字式血氧计。 Patent No. ZL97196522.6 invention patent application discloses a digital oximeter. 图IA为与传感器连接的数字式血氧计的示意图。 FIG IA is a schematic diagram of a digital oximeter connected to the sensor meter. 如图1所示,数字式血氧计101和传感器102,在实际测量时,需要将传感器102连接至带血样本,如病人的手指或耳垂。 As shown in FIG. 1, a digital oximeter 101 and sensor 102, in the actual measurement, the sensor 102 needs to be connected to a blood sample, such as a patient's finger or earlobe.

[0004] 由上述可知,虽然可通过上述血氧计进行测量,但是其缺点在于:对于医务人员而言,在诊室中会存在大量的线缆,增加工作的难度和某些不可预料的风险。 [0004] From the foregoing, although the above can be measured by the oximeter, but the disadvantage is that: for medical personnel, there will be large number of cables in the office, some unexpected increase the difficulty and risks of the work. 此外, 会导致对病人活动的拘束,增加病人的不适感,无法测量到人体在自然状态下的血氧参数和脉率参数。 In addition, the patient will lead to binding activity, increased patient discomfort, unable to measure the pulse rate and blood oxygen parameters parameters of the human body in its natural state.

[0005] 因此,为解决上述问题,目前还存在一种便携式血氧计,例如,指夹血氧计。 [0005] Thus, to solve the above problems, there exists a portable oximeter, e.g., clamp finger oximeter. 虽然便携式血氧计可解决监护仪存在的线缆多、造成工作不便且测量不准的问题,但是,该便携式血氧计不能够将所测量的数据实时传输到专用的数据中心进行监测和分析。 Although portable oximeter solve existing monitor cable causing a lot of inconvenience and measurement problems are not allowed to work, but this portable oximeter can not be measured in real-time transmission of data to a dedicated data center monitoring and analysis .

[0006] 为解决不能实时传输数据的问题,申请号为200380102580.5、公开号为CN 1708255A的中国发明专利申请公开一种具有远程通讯能力的手指血氧计,具体内容见该申请文件。 [0006] In order to solve the problem can not be real-time transmission of data, application number 200380102580.5, Publication No. CN 1708255A Chinese invention patent application discloses a finger oximeter with remote communication capabilities, the specific content of the application documents. 虽然该血氧计能够通过无线方式传输数据,但是,该血氧计的缺陷在于增加无线通信功能后,功耗也相应的增加;对于电路的电源管理方面,主要由远程监测设备端的观测者操作,该观测者启动发送信号的开关以启动/关闭手指血氧计,即通过人为方式控制其电源的启动与否,同时其控制的是整体的供电与否。 Although the oximeter capable of wireless transmission of data, however, defective in that the oximeter is increased after a wireless communication function, the power consumption increases accordingly; for the power management circuitry, the main device by the remote monitor terminal operation observer the observer sends a signal to start switching on / off finger oximeter, i.e., power control which starts by artificially or not, while it is the overall control of the power supply or not. 这种方式的缺点在于, 如果需要连续监测,电源将一直开启,对于测量电路、RF电路的供电就是始终存在的, 如图IB所示。 The disadvantage of this approach is that continuous monitoring if desired, the power supply has been turned on, the measuring circuit, RF power supply circuit is always present, as shown in Figure IB. 这样将造成功耗较大、使用时间较短。 This will result in higher power consumption, using a shorter time. 只有通过缩短单次使用时间、关闭设备来延长设备的工作时间,这样,造成使用不便。 Only by reducing single-use time, turn off the device to extend the working hours of the equipment, so inconvenient to use.

[0007] 对于一些特殊的应用,人体的血氧参数需要被无拘束的长时间监护,如对新生儿的监护,这时,如何降低功耗、延长无线血氧脉搏仪的连续工作时间,就成为重要问题。 [0007] For some special applications, the body's blood oxygen parameter takes a long time to be unfettered care, such as care for newborns, then, how to reduce power consumption and extend the working hours of continuous wireless pulse oximeter instrument, it It has become an important issue.

[0050] 图4是本发明再一个实施方式的血氧计构成示意图。 [0050] FIG. 4 is a further embodiment of the present invention, a schematic configuration of an oximeter embodiment. 如图4所示,该血氧计400 包括测量单元401、控制单元402、通信单元403和供电单元405 ;其中,测量单元401、 供电单元405、通信单元403与图2、3类似,此处不再赘述。 4, the oximeter 400 includes a measuring unit 401, control unit 402, the communication unit 403 and a power supply unit 405; wherein, a measurement unit 401, the power supply unit 405, the communication unit 403 is similar to FIG. 3, where No longer.

[0051] 在本实施方式中,处理单元402a可包括: [0051] In the present embodiment, the processing unit 402a may comprise:

[0052] 参数识别单元,用于对测量单元401传送的相关参数进行处理,即该参数识别单元用于判断是否接收到相关参数,若判断的结果为是,则判断当前时刻所接收到的相关参数是否准确,若判断结果为准确,则将该相关参数进行储存。 [0052] Parameter identification unit for measuring the relevant parameters of the transmission processing unit 401, i.e., the parameter identification unit for determining whether a relevant parameters, if the determination result is YES, it is determined that the current time related to the received parameter is accurate, if the determination result is accurate, then the parameters for storage.

[0053] 因为测量单元401启动后,需要一定的时间来调整参数设置,计算出准确值。 [0053] Because the measuring unit 401 starts, take some time to adjust parameters, calculate the exact value. 但是,这个时间根据测量环境的不同而变化,这样,可根据当前时刻测量的相关参数识别出当前测量的相关参数是否准确,其中可采用如下方式:至少计算一次当前时刻接收到的相关参数与前一时刻接收到的相关参数的差值;判断所述差值是否小于预设值;若判断结果为是,则当前时刻接收到的相关参数准确。 However, this time varies depending on the measurement environment, so, can identify the current correlation parameter measurement is accurate according to the relevant parameters of the current time measurement, which can be used in the following manner: calculating at least one parameter associated with the received current time before a time difference of the received parameters; determining whether the difference is less than a preset value; if the judgment result is YES, the current time of the received parameters accurately. 若连续计算三次时,其过程如下: 第一次计算当前时刻,即t时刻接收到的相关参数与前一时刻,即t-Ι时刻接收到的相关参数的差值Kl;判断该差值Kl是否小于预设值;若判断结果为是,则计算t+Ι时刻接收到的相关参数与第t时刻接收到的相关参数的差值K2 ;判断该差值K2是否小于预设值; 若判断结果为是,则计算t+2时刻接收到的相关参数与t+Ι时刻接收到的相关参数的差值K3;判断该差值K3是否小于预设值;若判断结果为是,则说明当前t+3时刻所接收到的相关参数准确。 If the calculated continuously three times, the process is as follows: first calculating a difference Kl current time, i.e., time t received parameters associated with the previous time, i.e., t-Ι received time-related parameter; Analyzing the difference Kl is smaller than a preset value; if the judgment result is YES, the calculation of the time difference t + Ι K2 received parameters received at time t associated with the first parameter; K2 is determined whether the difference is less than a preset value; if Analyzing the result is YES, the calculated difference value K3 t + 2 received time-related parameters and the received parameters related to the time t + Ι; determining whether the difference is less than a predetermined value K3; if the judgment result is YES, then the current time t + 3 the received parameters accurately. 这样,通过参数识别单元实现对测量单元401测量状态的识别,准确判断参数测量的工作状态,避免产生测量误差。 In this manner, identification is achieved by means of measuring the parameter identification unit 401 of the measurement state and accurately determine the operating state parameter measurements, to avoid measurement errors.

[0056] 在本实施方式中,测量单元201、301、401可分别在控制单元202、302、402的控制下,按照一定的时间间隔周期性地测量相关参数,且在该时间间隔内停止对测量单元201、301和401供电。 Under [0056] In the present embodiment, the measurement units 201,301,401 respectively in the control unit 202,302, 402, in accordance with a certain time interval is periodically measured parameters, and stops in the time interval power measuring unit 201, 301 and 401.

[0057] 图7是本发明实施方式中供电过程示意图。 [0057] FIG. 7 is a schematic diagram of the power supply process in the embodiment of the present invention. 如图7所示,当测量单元201、301 和401周期性测量相关参数时,仅在测量时间T2对测量单元201、301和401供电,而在测量的时间间隔Tl内停止对测量单元201、301和401供电,并且在周期性测量过程,即通信的时间间隔(T3)内,供电单元205、305和405也停止对通信单元203、303和403供电;当通信单元203、303和403传输相关参数时,在数据传输过程(T4)中,供电单元205、305和405停止对测量单元201、301和401供电,因此,与现有技术相比,该血氧计可大幅度减少能量的消耗,延长其工作时间。 As shown in FIG 7, when the measurement unit 201, 301 and 401 periodically measuring the relevant parameters, only the measured time T2 201, 301 and 401 of the power supply measurement unit and the measurement time measuring unit 201 is stopped interval Tl, power supply 301 and 401, and a periodic measurement, i.e. within a time interval (T3) in communication, power supply units 205, 305 and 203, 303 and 405 also stops the power supply to the communication unit 403; 203, 303 when the communication unit 403 and transmission when the relevant parameters, during the data transmission (T4), the power supply units 205, 305 and 405 stop generating the measurement units 201, 301 and 401, and therefore, as compared with the prior art, the oximeter can significantly reduce energy consumption and prolong their working hours.

[0058] 其中,测量时间T2取决于参数识别单元。 [0058] wherein the measurement time T2 depends on the parameter identification unit. 并且传输相关参数所用的时间T4取决于所传输数据量的大小。 And the transmission parameters used depends on the amount of time T4 of the data transfer size.

[0059] 由上述可知,通过对测量单元和通信单元的工作时间进行合理切换,使得在空闲状态下的单元不消耗能量,从而减少能量消、延长该血氧计的工作时间,解决了现有技术中存在的技术问题。 [0059] From the above, by the measurement unit and a communication unit switching operation for some reasonable time, so that the cell in the idle state does not consume energy, so as to reduce energy consumption, to extend the working time of the oximeter, solves art that the technical problems.

[0072] 图6是本发明一个实施方式的血氧计的工作流程图。 [0072] FIG. 6 is a flowchart of an embodiment of the oximeter of the present invention. 如图6所示,该血氧计可采用如下工作方式: 6, the oximeter may be adopted working methods:

[0073] 在该血氧计开始工作时,系统状态初始设置为测量状态。 [0073] When the oximeter to work, the system status is initially set to the measurement state.

[0074] 步骤601,启动测量单元401开始测量相关参数,且任务管理单元402b控制供电单元405停止为通信单元403供电,从而减少能量消耗; [0074] Step 601, the measurement start unit 401 starts measuring the relevant parameters, and a task management unit 402b controls the power supply unit 405 stops power supply to the communication unit 403, thereby reducing energy consumption;

[0075] 在本实施方式中,任务管理单元402b可控制供电单元405周期性为测量单元401 供电,如图7所示,在时间间隔Tl内停止供电,在测量时间T2内供电。 [0075] In the present embodiment, the task management unit 402b controls the power supply unit 405 may periodically power measurement unit 401, as shown in the time interval Tl to stop power supply, the power supply 7 in the measuring time T2. 这样,该测量单元401可周期性测量相关参数,因此,由于该供电单元405在测量时间T2内供电,在时间间隔Tl不供电,进一步减少能量消耗; Thus, the measuring unit 401 may periodically measure the relevant parameters, and therefore, since the power supply unit 405 in the measurement time T2, the time interval Tl power is not supplied to further reduce energy consumption;

[0076] 步骤602,处理单元402a对相关参数进行处理可采用如下方式:参数识别单元判断是否接收到相关参数,若判断结果为是,则对接收到的相关参数进行分析,判断当前时刻接收到的相关参数是否准确;若判断结果为是,则传送相关参数至存储单元404 进行保存,此时,停止对测量单元401供电。 [0076] Step 602, the processing unit 402a of the appropriate parameters can be processed in the following manner: the parameter identification unit determines whether the received parameters, if the judgment result is YES, the docking analyzes the received parameters, determining the current time received the accuracy of the parameters; if the judgment result is YES, the relevant parameters is transmitted to the storage unit 404 is saved, at this time, the measurement unit 401 stops power supply. 其中,参数识别单元对相关参数进行处理可采用如下方式:如图8所示,判断是否接收到相关参数(见步骤801),若判断结果为是,则判断所接收的相关参数是否准确(见步骤802),若判断结果为准确,则保存该相关参数,停止对测量单元401供电(见步骤803)。 Wherein the parameter identification means of the appropriate parameters can be processed in the following manner: 8 determines whether the received parameters (see step 801), if it is determined whether the result is YES, it is determined that the received parameters related to the accuracy (see step 802), if the determination result is accurate, then the parameters stored, the measurement unit 401 stops power supply (see step 803). 其中, among them,

[0077] 如图9所示,为本发明实施方式中参数识别单元判断所接收的相关参数是否准确的流程图。 [0077] As shown in FIG. 9, the embodiment determines the parameter identification unit received parameters accuracy flowchart of embodiments of the present invention. 如图9所示,可采用如下方式:若计算一次,则计算当前时刻所接收到的相关参数与前一时刻所接收到的测量参数的差值K(见步骤901);然后判断所计算的差值K均小于预设值(threshold),若判断结果为是,则说明当前所接收到的相关参数准确。 9, can be used in the following manner: If the calculation time, the measurement parameter K is calculated difference current time received parameters associated with the received previous time (see step 901); and determining the calculated K is less than the difference between the preset value (threshold), if the judgment result is YES, then the currently received parameters accurately.

[0078] 步骤603,判断是否对处理后的相关参数进行传输;若判断结果为是,则执行步骤604 ; [0078] Step 603 determines whether the process relevant parameters transmitted; if the judgment result is YES, a step 604 is executed;

[0079] 步骤604,对参数识别单元所处理后的相关参数进行压缩,这样,可减少传输的数据量的大小,从而进一步减少数据传输时间,减少能量的消耗。 [0079] Step 604, after the relevant parameters of the process parameter identification unit is compressed, so can reduce the size of the amount of data transmitted, further reducing the data transmission time, reduced energy expenditure. 当然,本发明还可不对上述相关参数进行压缩而直接传输。 Of course, the present invention is the above-mentioned parameters may not be transmitted directly compressed.

[0080] 若在步骤602中,测量单元401周期性测量相关参数,则参数识别单元也周期性对相关参数进行处理和保存。 [0080] When stored in step 602, the measurement unit 401 periodically measuring the relevant parameters, the parameter identification unit also periodically process and relevant parameters. 此时,压缩单元所压缩的相关参数应该为多次测量的相关参数的准确值。 At this time, the compressed compression unit should be accurate values ​​for the parameters related parameters of multiple measurements.

[0081] 步骤605,压缩数据完成后,对通信单元403供电,并传输压缩后的相关参数。 [0081] Step 605, the compressed data is completed, the power supply to the communication unit 403, and transmits the compression parameters.

[0082] 图11为本发明具体实施方式的血氧计的工作流程图。 [0082] FIG. 11 is a flowchart of the oximeter specific embodiments of the present invention. 以下参照附图11对一个单独的测量状态与通信状态的周期性启动、停止和任务切换的具体实施过程进行说明。 Described below with reference to FIG. 11 for a single measurement condition and a communication state periodically start, stop, and the specific implementation of task switching.

[0083] 如图7所示,在本实施方式中,测量单元401周期性测量相关参数,在测量时间T2内进行测量,在测量的时间间隔Tl内不进行测量,因为在周期性测量过程中,供电单元405不对通信单元403供电,且在时间间隔Tl内也不对测量单元401供电。 [0083] 7, in the present embodiment, the measurement unit 401 periodically measuring the relevant parameters, within the measuring time T2, the measurement is not performed at the measured time interval Tl, because periodic measurement process , the power supply unit 405 does not supply the communication unit 403, and not the power supply unit 401 for measuring the time interval Tl. 其中,总的周期性测量的时间也是通信的时间间隔T3,T4是数据传输的时间。 Wherein the total measurement time is periodic communication time interval T3, T4 is the time of data transmission. [0084] 其中,总的周期性测量的时间或通信的时间间隔可按照时间m来设定,或者按照测量过程中周期性测量的次数N2来设定,如图7所示为5次。 [0084] wherein the total communication time, or periodic time interval measured in time m may be set according to the number N2 or periodic measurement of the measurement process is set, as shown in FIG 7 to 5. 以下以总的周期性测量的时间Nl为例进行说明。 The total time of periodic measurements Nl described as an example.

[0085] 在本实施方式中,通过定时器来对测量单元401和通信单元403的工作时间进行切换。 [0085] In the present embodiment, the switching to the measurement unit 401 and the communication unit 403 by the timer operating time. 预先设置测量的时间间隔Tl和通信的时间间隔T3。 Measuring a preset time interval Tl, and a communication interval T3.

[0086] 血氧计400开始工作,测量单元401和通信单元403都没有被供电。 [0086] The oximeter 400 to work, a measuring unit 401 and the communication unit 403 are not powered.

[0087] 步骤1101,启动定时器中断,用于计时。 [0087] Step 1101, starts a timer interrupt for timing.

[0088] 步骤1102,计算当前的测量等待时间T和通信等待时间N,测量等待时间T和通信等待时间N如图7所示。 [0088] Step 1102 calculates the current measurement waiting time T and the communication latency N, measuring waiting time T and the communication latency N as shown in FIG.

[0089] 步骤1103,血氧计400的初始状态设置为测量状态,进入测量状态,启动测量单元401以时间间隔Tl周期性测量相关参数,并利用参数识别单元对该相关参数进行处理后保存到存储单元404中; [0089] Step 1103, the initial state of the oximeter 400 is arranged to measure the state and enters the measurement state, the measurement start unit 401 to save the time interval Tl after periodic measurement parameters, and the parameters using the parameter identification processing means the storage unit 404;

[0090] 其中,在测量状态中,供电单元405停止对通信单元403供电,并且在时间间隔Tl停止对测量单元401供电。 [0090] wherein, in the measurement state, the power supply unit 405 stops supplying power to the communication unit 403, Tl and stops the power supply unit 401 for measuring time intervals.

[0091] 测量单元401进行周期性测量可采用如下方式: [0091] The measurement unit 401 can be periodically measured in the following manner:

[0092] 判断测量等待时间T是否大于测量的时间间隔Tl,若判断结果为是,则该血氧计400的供电单元405为测量单元401供电,此时停止测量的时间间隔Tl的计算,启动测量单元401进行测量,且使用参数识别单元对相关参数进行处理,获得准确值后停止测量和供电,此次测量时间为T2,T2的时间长度取决于具体的测量过程和参数识别过程。 If [0092] determines whether the measured time T is greater than the waiting time interval Tl measured, if the judgment result is YES, the oximeter 405 power supply unit 400 to measure the power supply unit 401, when the measured stop time interval calculation of Tl, starting measurement unit 401 is measured, and the parameter identification processing means of the appropriate parameters, after the power supply is stopped, and accurate measurement value, the measurement time is T2, T2 is the length of time depends on the specific parameters of the measurement process and the recognition process. 停止测量时,将T清零并重新计数,等待下一个Tl时间间隔的到来。 When the measurement is stopped, the counter T is cleared and again, waiting for the arrival of a time interval Tl. 当系统状态为测量状态时,不断重复以上过程。 When the system state is a measurement state, repeating the above process.

[0093] 步骤1104,判断通信等待时间N是否达到预先设置的时间T3,即通过判断周期性测量过程的总时间Nl是否达到预先设定的时间T3来进行判断; [0093] Step 1104, the communication latency is determined whether N reaches the preset time T3, i.e., whether the predetermined time is determined by periodically measuring the total time during Nl T3 to be judged;

[0094] 步骤1105、1106,若在步骤1104中判断结果为达到T3,则说明系统状态为通信状态。 [0094] Step 1105 and 1106, if the result of the determination in step 1104 reaches T3, then the system state is the communication state. 在通信状态,停止对测量等待时间T的计数,停止对测量单元401供电,开始对之前测量状态中所测得的相关参数进行压缩,然后启动通信单元403,将压缩后的数据全部发送完毕。 In the communication state, stopping counting the measurement standby time T, to stop power supply to the measurement unit 401 starts the parameters before the measuring state in the measured compression, and then starts the communication unit 403, all the data will be compressed sent.

[0095] 步骤1107,将通信等待时间N全部置零,系统状态返回为初始状态。 [0095] Step 1107, the communication latency N all zero, the system state returns to the initial state.

[0096] 至此为止,一个单独的测量状态与通信状态的周期性启动、停止和任务切换的具体实施过程结束。 [0096] Thus far, a single measurement state and communication state is activated periodically, the end stop, and the specific implementation of task switching.

[0097] 此外,在本发明的另一个实施方式中,还可采用按照设定的周期性测量的次数来判断是否进入通信状态。 [0097] Further, in another embodiment of the present invention, it may be employed in accordance with the number of periodic measurement set to determine whether the communication state.

[0098] 这样,预先设置周期性测量的次数X,如图7所示为5次,则在步骤1104中判断周期性测量的次数Nl是否达到预先设置的次数X,若达到则说明进入通信状态。 [0098] Thus, the number of periodic measurement of X set in advance, as shown in FIG 5 times, periodic measurements determined in step 1104 whether the number Nl preset number X, when the communication state reached then the .

[0099] 由上述可知,通过该方法,使得在测量工作时间,停止对通信单元供电,且在通信工作时间,停止对测量单元进行供电,从而减少了该血氧计的能量消耗,延长该血氧计的工作时间,解决了现有技术中存在的技术问题。 [0099] From the above, by this method, so that the time measurements, the communication unit power is stopped, and the communication operation time measurement unit for power supply is stopped, thereby reducing power consumption of the oximeter, the extension of the blood oximeter operating time, solves the technical problem present in the prior art.
