技术领域technical field
本发明涉及医疗器械用的胎儿监护仪，更具体的说，涉及一种利用胎儿监护仪进行全方位监护胎儿安全的方法。 The invention relates to a fetal monitor used in medical equipment, and more specifically, relates to a method for comprehensively monitoring fetal safety by utilizing the fetal monitor. the
背景技术Background technique
胎儿监护始于60年代，它是借助于胎心电子监护仪监测胎心率变化的常用方法。在胎儿宫内死亡的病人中约2/3发生于产前，而其中绝大多数发生于胎盘功能不良的高危妊娠。产前胎心率监护的目的是让高危孕妇在治疗疾病的同时，让胎儿达到良好的生长发育，做到在胎儿受损伤前娩出，以减少产前死亡。 Fetal monitoring began in the 1960s, and it is a common method for monitoring fetal heart rate changes with the help of fetal heart rate electronic monitors. About 2/3 of the patients with intrauterine fetal death occurred in prenatal period, and most of them occurred in high-risk pregnancies with poor placental function. The purpose of prenatal fetal heart rate monitoring is to allow high-risk pregnant women to achieve good growth and development of the fetus while treating the disease, so that the fetus can be delivered before the fetus is damaged, so as to reduce prenatal death. the
在医学方面总结了如下的参数：(1)、对胎儿瞬时心率：胎儿每两次心跳时间间隔的倒数，反映胎儿心功能变化。(2)、宫缩压力：孕妇子宫收缩产生的张力。可以通过内测法和外测法测量到。(3)、宫压调零：使用外测法测量孕妇子宫收缩张力时必须预先设定的相对零点，相对零点的数值可调。(4)、压力相对值：使用外测法得到子宫收缩张力相对与零点的数值。(5)、胎动：胎儿在孕妇子宫中的运动。 The following parameters are summarized in the medical field: (1), instantaneous heart rate of the fetus: the reciprocal of the time interval between two heartbeats of the fetus, reflecting the change of fetal heart function. (2) Uterine contraction pressure: the tension produced by the contraction of the pregnant woman's uterus. It can be measured internally and externally. (3) Uterine pressure zero adjustment: the relative zero point must be preset when using the external measurement method to measure the contraction tension of the pregnant woman's uterus, and the value of the relative zero point can be adjusted. (4) Relative value of pressure: use the external measurement method to obtain the relative value of uterine contraction tension and zero point. (5), fetal movement: the movement of the fetus in the womb of the pregnant woman. the
胎动是胎儿情况良好的表现。胎动正常预示着胎儿健康。胎儿活动度与胎盘功能有关，正常妊娠18～20周时孕妇可感觉胎动，随着孕龄的 增加，胎动逐渐变强，次数增多，在妊娠29～38周时达到高峰，至分娩前两周胎动稍有减少，过期妊娠则胎动明显减少。胎动减少或消失预示胎儿缺氧或即将死亡，是胎儿需要立即抢救的警报信号。一般认为，从胎动消失到胎心消失可长达12～48小时，如在此期间及时终止妊娠，仍可能得到活婴。另外，如果突然胎动增加后停止，则说明胎儿因急性宫内窘迫而死亡，常见的原因是脐带缠绕或受压。孕妇单凭定期到医院做产前检查是不够的，还应进行自我监测。具体做法就是让孕妇自数胎动，根据胎动每天的变化规律，通常采用的方法是妊娠后28周孕妇每天早、中、晚在固定的时间各数1小时胎动，3次胎动总数乘以4即为12小时胎动数，称为每日胎动数。每位孕妇都有自己的胎动数，正常每日胎动数约30～40次。如突然出现胎动数的增加或减少，则应立即去医院做进一步检查，不可延误，以免发生意外。 Fetal movement is a sign that the fetus is in good condition. Normal fetal movement indicates a healthy fetus. Fetal activity is related to placental function. Pregnant women can feel fetal movement at 18-20 weeks of normal pregnancy. With the increase of gestational age, fetal movement gradually becomes stronger and more frequent. It reaches a peak at 29-38 weeks of gestation and reaches two weeks before delivery. Fetal movement is slightly reduced, and fetal movement is significantly reduced in overdue pregnancy. The reduction or disappearance of fetal movement indicates that the fetus is hypoxic or is about to die, and it is an alarm signal that the fetus needs to be rescued immediately. It is generally believed that it can take up to 12 to 48 hours from the disappearance of fetal movement to the disappearance of fetal heart rate. If the pregnancy is terminated in time during this period, a live baby may still be obtained. In addition, if the fetal movement suddenly increases and then stops, it means that the fetus died of acute intrauterine distress, usually due to entanglement or compression of the umbilical cord. It is not enough for pregnant women to go to the hospital for prenatal check-ups on a regular basis, and self-monitoring should also be carried out. The specific method is to let the pregnant woman count the fetal movement by herself. According to the daily change rule of the fetal movement, the usual method is to count the fetal movement for 1 hour at a fixed time every morning, noon and evening after 28 weeks of pregnancy. The total number of 3 fetal movements is multiplied by 4. It is the number of fetal movements in 12 hours, which is called the number of daily fetal movements. Every pregnant woman has her own fetal movement count, and the normal daily fetal movement count is about 30 to 40 times. If there is a sudden increase or decrease in the number of fetal movements, you should immediately go to the hospital for further examination without delay to avoid accidents. the

进一步，所述的全方位监护胎儿安全的方法还包括有胎儿睡眠唤醒监护，通过宫缩压探头的震动和通过宫缩压探头发出的高频刺激声音来唤醒胎儿。胎儿睡眠唤醒功能是为了在监护过程中唤醒睡眠中的胎儿，便于更好的监护胎儿在活动过程中心率的变化，从而真实的反映胎儿的心脏功能。 Further, the method for all-round monitoring of fetal safety also includes fetal sleep wake-up monitoring, and wakes up the fetus through the vibration of the uterine pressure probe and the high-frequency stimulating sound emitted by the uterine pressure probe. The fetal sleep wake-up function is to wake up the sleeping fetus during the monitoring process, so as to better monitor the changes of the fetal heart rate during the activity, so as to truly reflect the fetal heart function. the
本发明中还可以通过胎动打标器由孕妇手动记录胎动情况。 In the present invention, the fetal movement situation can also be manually recorded by the pregnant woman through the fetal movement marking device. the
胎心率监护是依据多普勒效应实现的。我们知道，一定频率的超声波在传播中遇到障碍物时要发生反射，如果物体静止，则反射波频率和发射波频率相同，一旦物体运动，则反射频率会产生改变，朝声源运动物体反射波频率变高，而背向声源运动物体反射波频率变低，且物体运动速度越快，频率改变也就越大，这种效应就称之为多普勒效应。临床上就是利用超声波传感器发射超声波进入人体，遇到运动器官，如心脏，造成回波信号改变，经对回波信号进行处理，提取出反映心脏活动的信息-心率。临床上用多普勒进行心率监护的最好部位是胎儿背朝着母体腹部的位置，如果胎儿是面朝母腹，手和脚将影响回波，胎儿的转身，使心脏偏离传感器所能照射区，回波信号将减弱，一些多普勒成份消失。 Fetal heart rate monitoring is based on the Doppler effect. We know that ultrasonic waves of a certain frequency will be reflected when encountering obstacles during propagation. If the object is still, the frequency of the reflected wave is the same as that of the emitted wave. Once the object moves, the reflected frequency will change, and it will reflect towards the moving object The frequency of the wave becomes higher, while the frequency of the reflected wave of the object moving away from the sound source becomes lower, and the faster the object moves, the greater the frequency change. This effect is called the Doppler effect. Clinically, the ultrasonic sensor is used to emit ultrasonic waves into the human body, and when it encounters a moving organ, such as the heart, the echo signal changes. After processing the echo signal, the information reflecting the heart activity-heart rate is extracted. Clinically, the best place to use Doppler for heart rate monitoring is the position where the fetus is facing away from the mother's abdomen. If the fetus is facing the mother's abdomen, the hands and feet will affect the echo, and the fetus' turning around will make the heart deviate from the radiation that the sensor can illuminate. area, the echo signal will weaken and some Doppler components will disappear. the
本发明所述的胎心率监护的操作方法包括如下步骤：(1)、安排孕妇处于平躺或半躺姿势；(2)、将随机附送的绑带环绕孕妇腹部，并调整好 松紧程度；(3)、采用听诊器、触诊或其他方式，大致确定胎心位置；(4)、挤出适量超声耦合剂，涂于胎心探头声学表面；(5)、将胎心探头放置于第(3)步确认的胎心位置，并适当移动探头确保超声耦合剂分布均匀，探头表面与孕妇腹部接触良好；(6)、适当调整探头位置和角度，适当调节音量，便能听到胎心音；(7)、将绑带扣入探头两边卡槽中。 The operation method of the fetal heart rate monitoring described in the present invention comprises the following steps: (1), arranging the pregnant woman to be in a lying or semi-lying position; (2), encircling the abdomen of the pregnant woman with the bandage attached randomly, and adjusting the degree of tightness; (3) Use a stethoscope, palpation or other methods to roughly determine the position of the fetal heart; (4) Squeeze out an appropriate amount of ultrasonic coupling agent and apply it to the acoustic surface of the fetal heart probe; (5) Place the fetal heart probe on the ( 3) Confirm the position of the fetal heart first, and move the probe appropriately to ensure that the ultrasonic coupling agent is evenly distributed, and the surface of the probe is in good contact with the pregnant woman's abdomen; (6), properly adjust the position and angle of the probe, and adjust the volume appropriately, and the fetal heart sound can be heard ; (7) Buckle the straps into the slots on both sides of the probe. the
在进行胎心率监护操作时还需要注意以下几点：(1)、进行胎心率监护前，应先检查探头工作是否正常。(2)、胎心探头传感器材料是陶瓷晶片，使用过程中应避免振动和跌落。(3)、胎心探头应避免被尖锐物体划伤，避免同硬质物体磕碰，以避免探头部件的机械损失或造成数据读取不正确。(4)、使用完毕后应将探头组件用软布或泡沫垫包裹妥善保存。 The following points should be paid attention to when performing fetal heart rate monitoring: (1) Before performing fetal heart rate monitoring, check whether the probe is working normally. (2) The sensor material of the fetal heart rate probe is a ceramic chip, and vibration and drop should be avoided during use. (3) The fetal heart rate probe should avoid being scratched by sharp objects, and avoid colliding with hard objects, so as to avoid mechanical loss of the probe parts or cause incorrect data reading. (4) After use, the probe assembly should be wrapped with soft cloth or foam pad and stored properly. the
宫缩压监护是对宫缩情况进行监护，宫缩压力是分娩强度的指标，临床上已表明宫缩的状况直接影响到胎心的活动和分娩，宫缩压监护所记录下的曲线能提供很多信息，如宫缩的强度、频度和持续时间，规则性和形状，宫缩可引起胎心率加快或减慢。目前进行胎心监护时配合有宫缩压监护，医务人员可以结合宫缩的情况对胎心率的变化进行诊断。 Uterine systolic pressure monitoring is to monitor the uterine contraction. Uterine contraction pressure is an indicator of labor intensity. It has been shown clinically that the uterine contraction directly affects the activity of fetal heart and delivery. The curve recorded by uterine systolic pressure monitoring can provide A lot of information, such as the intensity, frequency and duration, regularity and shape of uterine contractions, can cause fetal heart rate to increase or decrease. At present, fetal heart rate monitoring is combined with uterine systolic pressure monitoring, and medical personnel can diagnose changes in fetal heart rate in combination with uterine contractions. the
宫缩外压力监护是从母体腹部取得宫缩压力情况，当有宫缩发生时，腹壁的张力压迫置于其上的宫缩压探头，宫缩压探头将此压力转换成电信号。由此得到的压力电信号经过仪器的放大处理，最后输出显示或打印。 Uterine contraction pressure monitoring is to obtain the uterine contraction pressure from the mother's abdomen. When a uterine contraction occurs, the tension of the abdominal wall compresses the uterine contraction pressure probe placed on it, and the uterine contraction pressure probe converts the pressure into electrical signals. The resulting pressure electrical signal is amplified by the instrument, and finally output for display or printing. the
本发明所述的宫缩压监护的操作方法包括如下步骤：(1)、将绑带环绕孕妇腹部，并调整好松紧程度；(2)、将压力探头扣于绑带上，固定在 宫底二分之一处；(3)、在宫缩间歇期，将当前压力值设定为初始压力。 The operation method of the uterine systolic pressure monitoring of the present invention comprises the following steps: (1), wrap the strap around the abdomen of the pregnant woman, and adjust the degree of tightness; (2), buckle the pressure probe on the strap, and fix it on the fundus of the uterus One-half; (3) In the intermission period of the uterus, set the current pressure value as the initial pressure. the
进行宫缩压力监护时，应先检查探头工作是否正常，方法为用手按压传感器部分，压力显示数值应跟随改变。压力监护设备的正确使用对于确保患者安全特别重要，尤其对于探头部件，应采取以下措施避免探头部件出现机械性损伤，需要注意以下几点：(1)、进行宫缩压监护前，应先检查探头工作是否正常。(2)压力探头传感器材料是精密电桥，使用过程中应避免振动和跌落。(3)、压力探头应避免被尖锐物体划伤，避免同硬质物体磕碰，以避免压力部件的机械损失或造成数据读取不正确。(4)、使用完毕后应将探头组件用软布或泡沫垫包裹妥善保存。 When performing uterine contraction pressure monitoring, you should first check whether the probe is working normally. The method is to press the sensor part with your hand, and the pressure display value should change accordingly. The correct use of pressure monitoring equipment is very important to ensure the safety of patients, especially for the probe parts, the following measures should be taken to avoid mechanical damage to the probe parts, and the following points should be noted: (1). Whether the probe is working normally. (2) The sensor material of the pressure probe is a precision bridge, and vibration and drop should be avoided during use.
