Description

一种骨折实时监护方法及装置 One kind of real-time fracture monitoring method and apparatus

技术领域 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 technical field of monitoring fracture, particularly relates to an ultrasonic method and apparatus for monitoring the fracture using a real-time monitoring.

背景技术 Background technique

[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, fracture when handled properly or not timely brought consequences more serious, especially in the elderly and children in these vulnerable populations, fractures if not handled properly it can cause soft tissue infections, arthritis, severe might even limb deformities, so the guardianship of the fracture 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 main fracture care gap size is detected at the bone, soft tissue near the bone status 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-rays and CT to diagnose the situation and observe the bone, get X energy perspective view of the human skeleton and its soft tissues but the resolution is poor, and there is radiation damage to the human body; the effect of CT 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, now a multi-purpose ultrasound imaging techniques, such as the B-wide application. 这是因为超声具有很高的软组织分辨力。 This is because 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, ultrasonic imaging has been able to detect a depth in the range of nearly 20cm, obtain superior spatial resolution image 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 appropriate because ultrasound can not penetrate the bone as X-ray image, the image of the bone is 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 detected where the bone using ultrasound reflection properties. 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 very short time duration to transmit burst into the human body, since ultrasound can not penetrate the bone, so that almost all the bones of the reflected ultrasonic wave, the size of the gap can be detected reflected wave at the bone. 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, upon irradiation of soft tissue, soft tissue layers including skin, muscle, blood vessels, ultrasonic waves passing through different media at surface reflection occurs. 软组织只要有1%。 Soft tissue long as 1%. 的声阻抗差异,就能检测出其反射回波。 Acoustic impedance contrast, it can be detected reflection 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 levels in normal and diseased when it will be significantly different acoustic impedance, resulting in attenuation of ultrasound in soft tissue layers of change, the same echo waveform corresponding changes will occur. 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 can be analyzed and an ultrasonic echo in the bone tissue interfaces of different pathological conditions to obtain a soft and bone surrounding tissue.

发明内容 SUMMARY

[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 the above disadvantages of the prior art, there is provided a method and apparatus for real-time monitoring of fracture, via wireless communication technology to transfer the information to the monitoring center computer interaction, and the graphic display through the bone, soft tissue, temperature monitoring of each monitoring data. 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 learn the status of bone fracture size and soft tissue near the bone by transmitting an ultrasonic pulse train to be detected at the site of the ultrasonic echo waveform analyzed by temperature values ​​are used to determine the temperature near the fracture is normal, whether there is 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 is irradiated to the bone at the almost total reflection occurs, which echo amplitude is significantly higher than the amplitude of the ultrasonic echo in the soft tissues, the threshold value is set at a magnitude of the echo waveform classification, If the echo waveform Once wave amplitude exceeds the threshold, it is considered echo echo waveform comprising a bone, or that the ultrasound is not irradiated to the bone, the echo return signal is only 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 drawbacks typically requires manual movement of the probe, the transceiver transducer array probe of the present invention employs a phased array beamforming technique. 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。 Ultrasonic phased array, that is, by delaying, adjusting work ultrasonic probe (ultrasonic wave transmitting and receiving) each unit order to obtain the desired acoustic radiation field, and receiving selection technique. 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 the testing needs of different thicknesses.

`[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 at the human-computer interaction from platform 6 close, you can also consider using ZIGBEE module instead of GPRS module, ZIGBEE lower power consumption, working in bands, cheaper in Industrial Scientific Medical (ISM), and ZIGBEE 20~250 kbps operate at a lower rate, it is possible to meet the general needs of the application data transmission, the transmission range is generally between 10~IOOm, if the route through the inter-node communication and the relay, the transmission distance will be longer.

[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] In the broken arm now an example to illustrate the principle and waveform of the detection and analysis of the implementation process:

[0054] 图5、图6说明了回波波形检测的原理。 [0054] FIG. 5, FIG. 6 illustrates the principle of detection of the echo waveform. 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。 5 and 6, not only the various levels may be determined based on the delay echo soft tissue, and may set a threshold amplitude of the echo, the echo waveform to identify whether the echo contains bones. 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 at all levels of soft tissue based on the 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。 When just entering the ultrasonic detection site, echo delay smaller, it may be a skin and vein surface; echo time delay larger, possibly deep muscles and arteries. 图中横坐标为时间T,纵坐标为回波幅度A。 Abscissa is time T, the ordinate 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。 FIG 5 is a corresponding ultrasonic pulse echo does not include the case of bone, the arm when the ultrasonic irradiation, the ultrasonic wave enters the first surface of the skin and vein, emission occurs in the skin and veins, acoustic part, which is the first layer, echo R1, then the remainder of ultrasound through the skin and into the deep veins and arteries muscle tissue, muscle tissue and subsequent reflection and arteries, which is a reflection echo S2 of the second layer, and finally the ultrasonic emitted from the skin and veins, occurred when 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。 Each echo levels may be Rl, S2, and R3 are each determined after extraction out of the respective levels of the echo levels and echo profile database contains the bones (with the first layer Rl, S2 and a second layer, R3 and the second Layer) the results obtained were compared; FIG. 6 is a skeleton comprising a case where an echo ultrasonic pulse corresponding to a first received, echo Layer Rl and S2 in FIG. 5 is similar to the case where, when the ultrasonic penetration continues muscle when arteries and toward the bone, produces a third layer of Q3 totally reflected echoes of the bone, the bone is that because the total reflection, so that Q3 is significantly greater than the amplitude of 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。 Each echo levels may be Rl, S2 and Q3 respectively corresponding levels and extracted echo waveform contained in the database to determine bone after each echo levels (Rl with the first layer, S2 and a second layer, Q3 and third layer) were compared 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 is implementation of real-time monitoring process in accordance with FIGS. 7 and 8 described in detail:

[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: stored in the address information corresponding to fracture and guardians monitor associated therewith in the database platform for interactive data analysis module 6, 62, and stored in normal subjects and patients with fractures fractures of the fracture site data, including ultrasonic echo waveform and its corresponding bone gap size, the layers of soft tissue acoustic impedance and temperature values, wherein the ultrasonic echo waveform from shallow to deep has been divided into three levels for the received echo waveforms corresponding level comparing. 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。 Database there is also provided medical personnel data, including the normal range, the preset value and healing fracture data set for each case of a fracture (bone gap size, the layers of soft tissue acoustic impedance and temperature values) different from a scan area of ​​abnormality counter b healing counter points, points which means healing bone gap size reaches healed range, and the layers of soft tissue and acoustic impedance point temperature values ​​are within the normal range.

[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 personnel According to information established, including bone gap size, soft tissue layers of acoustic impedance and temperature of the normal range, in which the bone gap the size of the normal range is divided into a safe range and scope of healing safety range is bone gap size range of the dangerous situation does not occur, healing range up to the range of healthy levels of 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。 Database, data of different fracture patients fracture of the fracture site comprises different echo waveforms fracture healing and bone gap size of each stage, the soft tissue acoustic impedance layers corresponding to the different size of the gap when the bone (e.g., normal and hematoma, abscess, swelling) echo waveform and soft tissue layers corresponding to the acoustic impedance values ​​of normal and abnormal temperature (high, low) value when, and so as to compare the received data analysis.

[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 is an echo waveform at ten different arm bone gap, by a gap small to large number 01010, wherein a gap 0108 is the normal range of bone fractures, skeletal abnormalities 09010 is split, the gap is too great danger , when the comparison shows similar bone echo and 09,010 is considered skeletal anomalies may occur; twelve arm soft tissue echo waveform, which echo the range of 011-016 is the soft tissue in normal circumstances, to 017,018 soft tissue appeared echo waveform hematoma, 019,020 echo waveform abscess soft tissue occurs, 021,022 echo waveform when the soft tissue swelling, when the comparison shows soft tissue echo with 017,022 similar time is considered abnormal soft tissue may occur ; four arms temperature value, wherein the minimum temperature value 023, is the highest temperature value 024, 025 is less than any temperature value 023, 026 is an arbitrary value greater than the temperature 024, when the comparison result shows that when the temperature is 025,026 it is considered abnormal body temperature may occur.

[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] When the first step I care must be taken if the patient monitoring or scanning part during the subsequent steps there is a change I also need, otherwise step I may 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, the patient monitor transceiver selected scan area of ​​the probe according to their I fracture care area, the scanning area may be divided into three types: direct probe-covered area, the side of the probe beam is deflected 45 degrees region, most of the probe 90 side of the beam deflection of a large area, wherein the region comprises a small region, the small region includes a large area. 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 monitors directly scan the entire small region; if the region is selected, the monitor scans a small area, in the area again extended; if a large area is selected, the first small scanning 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 to initialize, monitor the wireless communication module through its connection 64 and the patient's own address of the selected scan region data transmission human-machine interactive platform 6, human 6 to find the interactive platform based on patient information of the received data in the data analysis module 62 in the database and select preset scanning area of ​​a counter associated with abnormal healing and healing points preset value of counter b.
