一种骨折实时监护方法及装置 Bone fractures real-time monitoring method and apparatus

技术领域 Technical Field

[0001] 本发明涉及骨折监护的技术领域,具体涉及一种运用超声波对骨折处实时监护的监护方法及装置。 [0001] The present invention relates to the field of fracture care, particularly to a method and apparatus for monitoring of ultrasound on fracture using a real-time monitoring.

背景技术 Background

[0002] 随着人们生活水平的提高,人们对自身的健康问题越来越重视,各种医疗监护设备层出不穷。 [0002] With the improvement of people's living standards, people are more and more attention to their own health problems, all kinds of medical monitoring equipment after another. 近几年来骨折有不断增加的趋势,当骨折处理不当或不及时带来的后果比较严重,尤其在老人和小孩这些弱势人群中,骨折的治疗若处理不当很可能造成软组织感染、关节炎,严重者甚至可能出现肢体畸形,所以对骨折处的监护变得十分重要。 In recent years, there is an increasing trend of fracture, when the consequences of improper handling or untimely fracture caused by a more serious, especially in the elderly and children in these vulnerable populations, fractures if not handled properly it may cause soft tissue infections, arthritis, severe may even limb deformities, so the fracture care becomes very important.

[0003] 骨折监护主要是检测骨骼处的缝隙大小、骨骼附近软组织的状况和体温值,以此来得知骨折的愈合情况。 [0003] The fracture care gap size mainly at detecting bone, soft tissue near the bone condition and temperature values, in order to learn the healing of fractures. 目前多采用X光和CT来对骨骼的情况进行观察与诊断,X光能获取人体骨骼的透视图,但它对软组织的分辨力较差,且对人体有辐射伤害;CT对软组织的诊断效果较好,但费用昂贵且同样对人体有辐射伤害。 The current use of X-ray and CT for observation and diagnosis of the situation bones, X is a perspective view of the human skeleton get energy, but its resolution is poor soft tissue, and radiation damage on the human body; CT in the diagnosis of soft tissue good, but expensive and the same radiation on the human body injury.

[0004] 而对于内脏器官的检查,现在多用超声成像的技术,如应用广泛的B超。 [0004] For the examination of internal organs, and now multi-purpose ultrasound imaging techniques, such as widely used B-mode. 这是因为超声具有很高的软组织分辨力。 This is because the ultrasound has high soft tissue resolution. 目前,超声成像已能在近20cm的检测深度范围,获取优于Imm的图像空间分辨力。 Currently, ultrasound imaging has been able to detect nearly 20cm depth range, access to superior spatial resolution images Imm. 但是对于骨骼检测来说,运用超声成像的方法不合适,因为超声无法像X光那样穿透骨骼,对骨骼的成像效果不是很理想。 But for bone detection, the use of ultrasound imaging method is not suitable, because ultrasound can not penetrate as bone like X-rays, bone imaging results are not very satisfactory. 然而却可以利用超声反射的特性来检测骨骼的情况。 However, it can be used to detect the ultrasonic reflection characteristics of bone situation. 当超声波以持续极短的时间发射脉冲串到人体内时,由于超声波无法穿透骨骼,所以在骨骼处超声波几乎全部反射回来,可以根据反射波来检测骨骼处的缝隙大小。 When the ultrasonic wave in a very short time continuously transmitting burst into the human body, since ultrasound can not penetrate the bone, in the bone so that almost all of the reflected ultrasonic wave, the reflected wave can be detected at the bone gap size. 同样,在照射软组织时,软组织各层包括皮肤、肌肉、血管,超声波在穿过不同的介质面时会发生反射。 Similarly, when irradiating the soft tissue, soft tissue layers including skin, muscle, blood vessels, ultrasonic wave passes through different media plane reflection occurs. 软组织只要有1%。 Soft tissue as long as 1%. 的声阻抗差异,就能检测出其反射回波。 Acoustic impedance differences can be detected its echo. 软组织有些层次在正常和病变时其声阻抗会明显不同,导致超声波在软组织各层中的衰减会发生变化,同样回波的波形也会出现相应的变化。 Some soft tissue level in normal and diseased will be significantly different acoustic impedance, resulting in soft tissue layers of ultrasonic attenuation will change in the same echo waveform and a corresponding change. 所以可以分析在骨骼以及不同软组织界面的超声反射回波来获得骨骼以及周围组织的病理情况。 It is possible to analyze the ultrasonic echo in the bone and soft tissue interface of different pathological conditions to obtain the bone and surrounding tissue.

发明内容 DISCLOSURE

[0005] 本发明的目的是克服现有技术存在的上述不足,提供一种骨折实时监护方法及装置,能通过无线通信技术把监护信息传送到人机交互中心,且通过图形显示骨骼、软组织、体温各监护数据的监护。 [0005] The object of the present invention is to overcome these shortcomings of the prior art, there is provided a method and apparatus for real-time monitoring of fracture, through a wireless communication technology to transmit information to the monitoring center computer interaction and graphic display of bone, soft tissue, Each temperature monitoring data of guardianship. 监护信息的获取是通过向被检测部位处发射超声脉冲串,对超声反射回波进行波形分析来获知骨骼裂缝的大小和骨骼附近软组织的状况,通过体温值来辅助判断骨折附近的体温是否正常,软组织是否有发炎等异常状况。 Monitoring access to information is to be detected at the site by emitting ultrasonic bursts of ultrasonic echo waveform analysis to learn the size and condition of the bones and soft tissue near bones crack by temperature values are used to determine the fracture near the body temperature is normal, Are soft tissue inflammation and other anomalies.

[0006] 由于超声波照射到骨头处时几乎发生了全反射,其反射回波幅度要明显高于超声波在软组织中的回波幅度,所以在对回波波形进行分类时设定一个幅度的阈值,若回波波形中有一回波幅度超过此阈值,则认为回波波形中包含骨骼的回波,否则认为超声波没有照射到骨骼,回波信号只是软组织的回波。 [0006] Since the ultrasonic irradiation to the bones of the almost total reflection occurs, the reflected echo amplitude was significantly higher than the amplitude of the ultrasonic echo in the soft tissue, so setting an amplitude threshold value when the echo waveform classification, If the echo waveform Once wave amplitude exceeds this threshold, then that echo echo waveforms contained bones, or that the ultrasonic irradiation to the bone no echo signal is only an echo of soft tissue.

[0007] 为了克服一般探头需要手工移动的缺点,本发明收发探头中的换能器阵列采用了相控阵的波束成形技术。 [0007] In order to overcome the shortcomings generally requires manual movement of the probe, the probe of the present invention receiving transducer array using a phased array beamforming techniques. 相控阵超声,就是通过延迟,调节超声探头中各单元的工作(发送和接收超声波)次序,以获得所需要的辐射声场,并进行选区接收的技术。 Phased array ultrasound is through delay, regulating the work of the ultrasonic probe unit (transmit and receive ultrasound) order to obtain the desired acoustic radiation field, and the constituency receives technology. 这样,在不移动或较少移动的情况下,用一个探头可以适应不同部位,不同厚度的检测需要。 Thus, without moving or moving less, with a probe can be adapted to different parts of different thickness testing needs.

[0015] 收发探头在发射时,控制模块根据病人选择的扫描区域控制发射模块依次扫描每个点。 [0015] receiving the probe in the launch control module scans through each point in the scan area based on patient selection control transmitter module. 对于某个点的扫描,控制模块根据当前要测量部位扫描点的位置信息,给出相控阵每个阵元的幅度和相位的控制信息,使得发射模块发射的超声波信号在相控阵的作用下能在该扫描点的方向上聚焦,然后控制模块控制发射模块发射脉冲串。 For the role of a point scanning, the control module to be measured based on the current site of the scanning spot location information, giving control information for each array element phased array amplitude and phase so as to transmit module transmits ultrasonic signal in phased array under the able direction of the scanning spot in focus, then the control module controls the transmission module transmits bursts. 发射模块通过收发探头发射第一个脉冲后就切换到接收状态。 Transmit module transmits through the first pulse after receiving the probe switches to receive state. 收发探头在接收时,因为接收同一扫描方向的反射回波,所以控制模块再根据相控阵每个阵元的幅度和相位的控制信息来合成信号,获得该扫描点方向处软组织各层次和骨骼的反射回波,交由接收模块处理,这也是接收到的第一个脉冲回波。 Transceivers when receiving the probe because the receiver echoes the same scanning direction, the control module and then synthesized signal based on the control information of each array element phased array amplitude and phase, access to the scanning direction at the point of soft tissue and bone at all levels The echo, by the receiving module handle, which is received by the first pulse-echo. 紧接着收发探头发送第二个脉冲,接收第二个脉冲……直到对该扫描点发射结束。 Then transceiver sends a second probe pulse, the second pulse is received until the scanning spot ...... emission end. 控制模块对第二个及其后来的超声脉冲的处理过程与第一个脉冲类似。 The control module for processing the second and subsequent ultrasonic pulses similar to the first pulse. 各脉冲之间时间间隔可以根据具体需要预先设定,满足所有病人不同部位的的骨骼测量需求,以保证对回波的处理速度且各脉冲回波波形不产生重叠。 Time interval between the pulses can be pre-set according to specific needs, to meet all patients in different parts of the skeleton measurement needs, in order to ensure processing speed and each pulse-echo echo waveform not overlap. 一个超声脉冲串中脉冲个数则可以通过稳定性测试由厂家预先设置一个固定值。 An ultrasonic burst pulse number can be pre-set by the stability test of a fixed value by the manufacturers. 处理好一个扫描点后,再接着处理下一个扫描点,直至覆盖整个骨折需要扫描的区域,从而无需移动探头的情况下就能扫描整个骨折处监护范围。 After the deal with a scanning spot, followed by processing the next scan point, until it covers the entire fracture area to be scanned, so that the next case without moving the probe can scan the entire fracture care range.

[0051 ] 如图4所示,本发明所用的无线通信模块,在实施中可采用GPRS模块来实现,其结构框图如图4所示。 [0051] FIG. 4, the wireless communication module used in the present invention, can be used in the implementation of the GPRS module to achieve, and its block diagram shown in Figure 4.

`[0052] 若病人居住处离人机交互平台6较近,也可以考虑用ZIGBEE模块来代替GPRS模块,ZIGBEE功耗更低,工作在在工业科学医疗(ISM)频段,价格更低廉,且ZIGBEE工作在20〜250 kbps的较低速率,能够满足一般数据传输的应用需求,传输范围一般介于10〜IOOm之间,如果通过路由和节点间通信的接力,传输距离将可以更远。 `[0052] If the patient lived from interactive platform 6 at close, you can also consider using ZIGBEE module instead of GPRS module, ZIGBEE lower power consumption in the industrial scientific medical (ISM) band, cheaper, and ZIGBEE operate at a lower rate 20~250 kbps, and can meet the application requirements of the general data transmission, the transmission range is generally between 10~IOOm, if through the inter-node communication relay routing and transmission distance will farther.

[0053] 现以手臂骨折为例,来说明波形检测与分析的原理和实现流程: [0053] Now with a broken arm, for example, to illustrate the waveform detection and analysis of the principles and implementation process:

[0054] 图5、图6说明了回波波形检测的原理。 [0054] Figure 5, Figure 6 illustrates the principle of echo waveform detection. 如图5和图6所示,不仅可以根据回波的延时来确定软组织的各个层次,并且可以通过设定回波幅度的阈值,来辨别回波波形中是否包含骨骼的回波。 As shown in FIG. 5 and 6, not only at all levels can be determined according to the soft tissue echo delay and echo amplitude can set thresholds to identify bone echo waveform contains an echo. 回波的延时存在差异,可以根据回波的延时来确定软组织的各个层次,由浅到深依次分为三层。 Echo delay differences can be determined according to various levels of soft tissue delay echo, from shallow to deep turn divided into three layers. 在超声波刚进入检测部位时,回波延时较小的,可能是表面的皮肤和静脉血管;回波延时较大的,可能是深层的肌肉和动脉血管。 Just enter in the ultrasonic detection site, echo delay the smaller, may be the surface of the skin and veins; echo time delay greater probably deep muscles and arteries. 图中横坐标为时间T,纵坐标为回波幅度A。 FIG abscissa is time T, the vertical axis is the echo amplitude A. 图5是一个超声脉冲对应的不包含骨骼的回波情况,当超声波照射手臂处时,超声波首先进入表面的皮肤和静脉血管,在皮肤和静脉血管处部分声波发生发射,这是第一层的反射回波R1,然后剩下部分超声波穿透皮肤和静脉血管进入深层次的肌肉组织和动脉血管,继而在肌肉组织和动脉血管中发生反射,这是第二层的反射回波S2,最后超声波从皮肤和静脉血管处射出时又发生一次反射,收到第三层反射回波R3。 Figure 5 is a corresponding ultrasonic pulse echo situation that does not contain bones, arm, when the ultrasonic irradiation, ultrasound first into the surface of the skin and veins and the veins in the skin portion acoustic emission occurs, this is the first layer echo R1, then the remaining part of the ultrasound to penetrate the skin and veins into the deep muscle tissue and arteries, and subsequent reflection in the muscle tissue and arteries, which is the echo of the second layer S2, the last ultrasound emitted from the skin and veins occur at the time and a reflection echo received third layer R3. 确定各层次的回波后可将各层次回波Rl、S2和R3分别提取出来与数据库中不包含骨骼的回波波形的相应层次(Rl与第一层,S2与第二层,R3与第三层)进行对比分析得出结果;图6是一个超声脉冲对应的包含骨骼的回波情况,收到第一、二层回波Rl和S2的情况与图5类似,当超声波继续穿透肌肉和动脉血管射向骨骼时,在骨骼处产生了全反射的第三层回波Q3,因为骨骼处是全反射,所以Q3的幅度要明显大于Rl和S2。 Determine the level of echo after echo can be at all levels Rl, S2 and R3 are extracted from the database does not contain bone echo waveform corresponding level (Rl with the first layer, S2 and second layer, R3 and the first three) the outcome of comparative analysis; Figure 6 is an ultrasonic pulse echo corresponding case containing bones, received the first and second floor echo Rl and S2 in the case of Figure 5 is similar to when the ultrasonic continue to penetrate muscle When fired bones and arteries, produced in the bone at the total reflection on the third floor echo Q3, because the skeleton is that of total reflection, so Q3 magnitude significantly greater than Rl and S2. 确定各层次的回波后可将各层次回波R1、S2和Q3分别提取出来与数据库中包含骨骼的回波波形的相应层次(Rl与第一层,S2与第二层,Q3与第三层)进行对比分析得出结果。 Determine the level of echo after echo all levels can be R1, S2 and Q3, respectively, contained in the database to extract bone echo waveform corresponding level (Rl with the first layer, S2 and second layer, Q3 and third Layer) analyzed the outcome.

[0055] 根据图7和图8详述本发明实时监护的实现流程: [0055] The present invention according to FIG. 7 and 8 detailing real-time monitoring of the implementation process:

[0056] 步骤1:在人机交互平台6的数据分析模块62的数据库中存入与之相关联的监护仪的地址和对应骨折监护人的信息,同时存入正常人和骨折病人骨折部位的骨折数据,包括超声回波波形及其对应的骨骼缝隙大小、软组织各层声阻抗和体温值,其中超声回波波形已被由浅到深划分为三个层次以便与接收到的回波波形的相应层次进行对比。 [0056] Step 1: deposit with the address and the corresponding information associated fracture guardian of the monitor in the interactive platform data analysis module 6 of 62 database, while normal subjects and patients with fractures into the fracture site of fracture data, including ultrasonic echo waveform and its corresponding bone gap size, soft tissue layers of acoustic impedance and temperature values, wherein the ultrasonic echo waveforms from shallow to deep has been divided into three levels so that the received echo waveform corresponding level were compared. 数据库还存有医务人员设置的相关数据,包括为每项骨折数据设置一个骨折情况(骨骼缝隙大小、软组织各层声阻抗和体温值)正常范围、不同扫描区域异常计数器a的预设值和愈合计数器b的愈合点数,其中愈合点数是指骨骼缝隙大小已达到愈合范围,且软组织各层的声阻抗和体温值都在正常范围内的点数。 There is also a database of medical personnel-related data set, including the normal range, the default value and healing fracture data set for each case of a fracture (bone gap size, soft tissue layers of acoustic impedance and temperature values) anomaly counter a different scanning area of Counter b healing points, points where healing means healing bone gap size range has been reached, and the acoustic impedance of the layers of soft tissue and temperature values are within the normal range of points.

[0057] 骨折情况的正常范围须由专门的医务人员根据相关资料建立,包括骨骼缝隙大小、软组织各层声阻抗和体温的正常范围,其中骨骼缝隙大小的正常范围又分为安全范围和愈合范围,安全范围为骨骼缝隙大小不出现危险情况的范围,愈合范围为骨骼缝隙大小达到健康人水平的范围。 The normal range [0057] fracture cases by specialized medical staff set up in accordance with the relevant information, including bone gap size, soft tissue layers of acoustic impedance and the normal temperature range in which normal bone gap size range is divided into range safety range and healing Security range is the range of dangerous situations bone gap size does not appear, heal range of people to achieve a healthy range levels of the bone gap size. 数据库中骨折病人不同骨折部位的骨折数据具体包括骨折愈合各阶段骨骼不同缝隙大小时的回波波形及其对应的骨骼缝隙大小,软组织各层声阻抗不同(如正常和出现血肿、脓肿、肿胀)时的回波波形及其对应的软组织各层声阻抗,体温值正常和不正常(过高、过低)时的值,以便于和接收到的数据进行比较分析。 Fracture fracture patients database data from different parts of the specific fracture include all stages of fracture healing bone echo waveform and its corresponding gap size, bone and soft tissue layers of different acoustic impedance different gap size (such as normal and hematoma, abscess, swelling) echo waveform and its corresponding soft tissue layers of acoustic impedance, body temperature was normal and abnormal (too high, too low) values in order to facilitate and received data were analyzed.

[0058] 比如有十个手臂骨骼不同缝隙时的回波波形,按缝隙从小到大依次编号为01010,其中0108为骨折时骨骼的正常缝隙范围,09010为骨骼异常裂开、缝隙过大的危险情况,当比较结果显示骨骼回波与09、010相似时,则认为骨骼可能出现异常情况;有十二个手臂软组织回波波形,其中011—016为正常情况时软组织的回波范围,017018为软组织出现血肿时的回波波形,019020为软组织出现脓肿时的回波波形,021022为软组织出现肿胀时的回波波形,当比较结果显示软组织回波与017022相似时,则认为软组织可能出现异常情况;有四个手臂体温值,其中023为最低体温值,024为最高体温值,025为任意小于023的体温值,026为任意大于024的体温值,当比较结果显示体温值为025、026时,则认为体温可能出现异常。 [0058] For example, there are dozens of arm bone echo waveform different time slot, according to the gap from small to large, numbered 01010, in which the 0108 gap range when normal bone fractures, skeletal abnormalities 09010 for the split, the gap is too great danger , when the comparison shows a similar bone echo with 09,010, then that may arise skeletal anomalies; twelve arm soft tissue echo waveform where the 011-016 range for the echo normal soft tissue, 017,018 for the soft tissue of the echo waveform hematoma, and 019,020 for the soft tissue of the echo waveform abscess, and 021,022 for the echo waveform soft tissue swelling time, when the comparison showed soft tissue echo and 017,022 similar, then think of soft tissue may appear abnormal situation ; with four arms temperature values, where 023 is the lowest temperature value, 024 is the highest temperature value, temperature value 025 is any less than 023, 026 is an arbitrary value greater than the temperature 024, when comparing the results show when the temperature is 025,026 , then that body may be abnormal.

[0059] 第一次监护时步骤I必须进行,其后的监护过程中若病人或扫描部位有变化时步骤I也需进行,否则步骤I可跳过。 [0059] The first time I care steps must be followed by the guardianship process, if the patient or scan the site when I also need to change step, otherwise I step can be skipped.

[0060] 步骤2:启动监护仪,病人根据自身骨折监护区域选择监护仪收发探头I的扫描区域,扫描区域可以分为三种:探头直接覆盖的小区域、探头侧边波束偏转45度的中区域、探头最侧边波束偏转90度的大区域,其中中区域包含小区域,大区域包含中小区域。 [0060] Step 2: Start the monitor, patient care area according to their fracture select the scan area I monitor transceiver probe, the scanning area can be divided into three types: a small area directly covered by the probe, the probe beam deflection side 45 degrees region, the probe beam deflector side edges 90 of large area, wherein the region comprises a small area, a large area including the small region. 若病人选择了小区域,则监护仪直接扫描整个小区域;若选择了中区域,则监护仪先扫描小区域,再向中区域扩展;若选择了大区域,则先扫描小区域,再向中区域扩展,最后向大区域扩展。 If the patient chose a small area, the monitor scan directly across a small area; if the area is selected, the monitor scans a small area, again in the area of expansion; if you choose a large area, then scans a small area, again Expansion in the region, and the expansion to a large area.

[0061] 步骤3:监护仪与人机交互平台6进行初始化通信,监护仪通过与其连接的无线通信模块64将自己的地址和病人所选择的扫描区域数据发送给人机交互平台6,人机交互平台6根据接收的数据在数据分析模块62的数据库中找到病人的信息并选择扫描区域相关的异常计数器a的预设值和愈合计数器b的愈合点数预设值。 [0061] Step 3: Monitor and interactive communication platform 6 is initialized, the monitor is connected via its wireless communication module 64 of the patient's own address and the selected scanning area data transmission interactive platform gives machine 6, human interactive platform 6 to find patient information based on the received data in the data analysis module 62 of the database and select the scanning area-related abnormality counter a preset counter b healing and healing preset points.

[0062] 步骤4:监护仪根据设置好的扫描区域依次对每个扫描点进行扫描并得出监护结果。 [0062] Step 4: Monitor sequentially scanned according to the settings for each scan point and draw a good scan area monitoring results. 扫描区域中某个点的具体实施过程是: Scan region point to a specific implementation process are:

[0063] 收发探头I根据骨折区域向骨折处某一点发射超声脉冲串并接收脉冲串回波,同时测温电路4开始测量此处的体温,收发探头I把接收的回波波形通过控制模块5传给程控放大器31,经过放大、滤波、检波、A/D转换后放入采样缓存器34和测温电路4测得的体温值一起进入编码模块35编码后传给无线通信模块36,无线通信模块36将数据发送给人机交互平台6,人机交互平台6通过与其连接的无线通信模块64接收数据。 [0063] I send and receive the probe according to the fracture to fracture at some point burst and emit ultrasonic echo received burst, while the temperature measurement circuit 4 starts measuring the temperature here, I receive the probe to echo waveform received by the control module 5 passed to programmable amplifier 31, amplified, filtered, detection, A / D converter 34 into the sample buffer and the temperature measuring circuit 4 measured temperature value into the encoding module 35 together with the encoded transmitted wireless communication module 36, a wireless communication module 36 sends the data exchange platform gives machine 6, 6 through its interactive platform to connect the wireless communication module 64 receives the data. 人机交互平台6的无线通信模块64接收到数据后首先通过解码模块63解码出回波波形或温度值,若是回波波形,则通过阈值辨别回波波形是否包含骨骼回波,然后显示平台61显示回波波形图,若是温度值则直接显示温度值。 After the interactive platform of wireless communication module 6 of 64 first receives the data decoded by the decoder module 63 echo waveforms or temperature, if the echo waveform, the thresholds to identify bone echo waveform contains an echo, then display platform 61 echo waveform display, if the temperature value directly display the temperature. 随后,数据分析模块62把显示的回波波形图或温度值与数据库中回波波形或温度值进行比较分析该点的愈合情况,得出回波波形图对应的骨骼缝隙大小和软组织各层声阻抗,从而判断该扫描点是否正常并得出监护结果。 Subsequently, the data analysis module 62 echo waveform display or temperature values or temperature values echo waveform database for comparative analysis of the healing of the point, draw echo waveform corresponding to the size of the bones and soft tissue layers gap sound impedance, in order to determine whether it is normal that the scanning spot and monitoring the results obtained.

[0064] 对该点进行扫描得到的监护结果包括回波结果和温度值结果。 [0064] the point of care scanned results include the results echo findings and temperature values. 在回波结果中又包含了骨骼状况结果和软组织状况结果,对于骨骼状况结果,显示平台61会显示骨骼缝隙的大小和判断结果,若骨骼缝隙大小在正常范围内则显示正常,否则显示异常,对于软组织状况结果,显示平台61会显示软组织各层次的声阻抗和判断结果,若声阻抗在正常范围内则显示正常,否则显示异常;温度值结果会显示骨折附近处的体温值和判断结果,若体温值在正常范围内则显示正常,否则显示异常。 Echo results also contains the results of the bone and soft tissue condition Availability result, the results for bone status, display platform 61 will show the size and the determination result bone gap, if the size of the bone gap within the normal range is normal, otherwise display abnormal, For soft-tissue condition results show platform 61 will display the soft tissue at all levels of the acoustic impedance and the determination result, if the acoustic impedance within the normal range will be displayed properly, otherwise the show abnormalities; temperature results are displayed temperature values and judgment results fractures vicinity of, If the temperature value is within the normal range it is normal, otherwise, it displays an exception. 只有当回波结果和温度值结果都为正常时,该点的扫描结果才为正常,否则为异常。 Only when the results echo findings and temperature are normal, scan results at this point only as normal, or as an exception.

[0065] 步骤5:得出一个点的扫描结果后,人机交互平台6开始对结果进行处理。 [0065] Step 5: The resulting scan results of a point, the interactive platform 6 starts to process the results. 若该扫描点结果正常,则进一步判断骨骼缝隙大小是否在愈合范围内,若在则异常计数器a维持原值,愈合计数器b加一统计次数,然后判断扫描范围是否完成,不在则直接判断扫描范围是否完成。 If the scanning spot is normal, it is further judged whether the size of the gap in the bone healing range, if maintaining the original value of the abnormality counter a, b heal counter plus a statistical frequency, and then determine whether the scope of the scan is complete, it does not directly determine the scan range It is complete. 若该扫描点结果异常,则异常计数器a加一统计次数,愈合计数器b维持原值,然后判断异常计数器a统计次数是否超过预设值,没超过则判断扫描范围是否完成,没完成则回到步骤4继续下一个点的扫描,完成则显示平台61显示该病人本次扫描的最终监护结果,最终监护结果包括异常计数器a的值和愈合计数器b的值,若愈合计数器b的值达到愈合点数,则显示基本愈合,否则显示一切正常,从而结束该病人本次的骨折扫描;若异常计数器a统计次数超过预设值,则异常计数器a和愈合计数器b自动归零且显示平台发出报警,相应的医务人员就可根据为监护仪赋予的地址确定是哪个病人出现问题并做及时的处理,从而结束该病人本次的骨折扫描。 If the scanning spot abnormal result, then add a statistical anomaly counter a number of times, healing counter b maintain the original value, and then determine a statistical anomaly counter number exceeds a preset value, no more than it is determined whether the scan range is completed, did not complete the back Step 4 Continue to the next point of the scan, the display platform to complete 61 shows the final result of the patient care of this scan, the final monitoring results include values and healing counter a b value anomaly counter, if the counter value of b healing achieve healing Points, it shows almost healed, or show everything is normal, thus ending the patient of this fracture scanning; if a statistical anomaly counter number exceeds a preset value, the abnormal counter a and b heal counter display platform auto zero and an alarm, appropriate medical staff can determine the address given for the monitor which patient problems and make timely treatment, thus ending the patient of this fracture scanning.

[0066] 若在某次使用时人机交互平台6的数据分析库62中找不到相似的存储数据与接收数据进行比较,则可以存入更多的数据对数据分析模块62中的数据库进行更新,以保证监护仪与人机交互平台6的正常使用与运行。 [0066] If the interactive platform data analysis library 62 6 can not find similar storage data is compared with the received data when a particular use, more data can be stored in the data analysis module 62 in the database updated to ensure monitor and interactive platform 6 of the normal use and operation.
