研制了一种新型便携式无创血压监测仪(体积4×6.5×14 cm，重量390g)，用于24小时血压监测，并对其临床适用性进行了研究。使用普通尺寸的袖带，这是有史以来开发的同类设备中最轻、最紧凑的。它是由可充电电池供电的。袖带由微型、低噪音、旋转式微泵加压。为了消除身体运动产生的噪音，使用了两个麦克风来区分柯罗特科夫的声音。在24小时内每隔1到60分钟自动测量收缩压(SBP)、舒张压(DBP)和心率(HR)。这些数据可以在记录器的半导体存储器中存储多达600次。测量后，用5×7.5×15厘米的附属微型分析仪打印出SBP、DBP和HR的平均值、标准差(SD)和趋势图。将该仪器测值与传统听诊法测值进行比较，SBP平均误差为-1.2±-4.7(SD)mm Hg，DBP平均误差为-2.7+/-5.0 mm Hg。两种方法测得的SBP和DBP的相关系数r分别为0.99和0.96(n=185)。在38名男性和31名女性正常血压受试者(平均随机血压：男性126+/-11/76+/-7；女性116+/-13/69+/-10)中，新记录仪记录的24小时平均血压男性为115+/-7.5(SBP)/70+/-6(DBP)+/-6，女性为106+/-6/63+/-5。新的记录仪使用方便，操作方便，在临床上可用于动态监测。
A new portable noninvasive recorder (4 X 6.5 X 14 cm in size, 390 g in weight) was developed for monitoring 24-hour blood pressure and its clinical applicability was investigated. Employing an ordinary-size cuff, this is the lightest and the most compact apparatus of its kind ever developed. It is powered by a rechargeable battery. The cuff is pressurized by a miniature, low-noise, rotary micropump. To eliminate noises resulting from body motion, two microphones are used to distinguish Korotkoff sounds. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) are measured automatically at intervals of 1 to 60 min throughout 24 hours. These data can be stored as many as 600 times in the recorder's semiconductor memory. After measurement, mean values; standard deviations (SD); and trendograms of SBP, DBP, and HR are printed out by means of an appurtenant, miniature analyzer measuring 5 X 7.5 X 15 cm. A comparison of values obtained with this new instrument and the values obtained with a conventional auscultatory method showed average errors of -1.2 +/- 4.7 (SD)mmHg for SBP and -2.7 +/- 5.0 mmHg for DBP. The correlation coefficient (r) of values obtained by two methods was r = 0.99 for SBP and r = 0.96 for DBP (n = 185). In 38 male and 31 female normotensive subjects (average casual BP: male 126 +/- 11/76 +/- 7 mmHg; female 116 +/- 13/69 +/- 10 mmHg), average 24-hour BP values recorded by the new recorder were 115 +/- 7.5 (SBP)/70 +/- 6 (DBP)mmHg for the males and 106 +/- 6/63 +/- 5 mmHg for the females. The new recorder seems to be convenient, easy to operate, and clinically useful in ambulatory monitoring.
