I. INTRODUCTIONWe developed a stationary type ambulatory inconti-nence monitor using a tin oxide semiconductor odor sensor. This was used for monitoring the excretion of disabled elderly. In this paper, we present a trial applica-tion of a portable type ambulatory incontinence monitor.II. MATERIALS and METHODSThe systems consists of a tin oxide semiconductor sensor, an air-pump, signal processing circuits, and a memory and display device (PC : NEC9800NX).1) Improvement of the tin oxide semiconductor odor sensorWe used TGS2600 series D1 for the stationary type monitor, a dual sided mounting type sensor which en-abled constant charged conditions of heating circuits (AC, DC) of 5V plus-minus 0.2V. For this trial, we used TGS 2400 series M1, a one-sided mounting type sensor. The heat circuits were driven by the pulse voltage appli-cation. The sensor signals were measured at a timing of 150msec after the application of the heater voltage. The housing of the sensor was a column of 9.2mm oute … More r dia-meter and 7.8mm in height. Weights is 1.1g.2) Air pumpaphragm Pump, 2002G(ASF made by Thomas Co.) was used. Applied voltage was DC6V. The air was sampled at a rate of 350ml/min continuously.3) SystemsThe tip of the vinyl chloride tube was placed at the coccyx between the diaper and the cover. Air was con-tinuously sampled through the tip of the tube using an air pump for 72 hours. The sensor signals were processed by the PC and results were displayed on a CRT. We used hard copies of the results for the investigation.III. RESULTSThe systems responded to urination and defecation. Response curve obtained at the time of urination showed spike like patterns. That obtained at the time of defeca-tion showed high plateau like patterns.IV. CONCLUSIONSWe used a method to transfer the signals direct to the PC. We plan to use a batch method by which the sensor signals will be continuously recorded on RAM and read by the PC. This method will be applicable for the portable type. The pulse driven sensor showed improved sensitivity especially to hydrogen sulfide and ethanol gases.The sensor as well as the pump driven at low power consumption that is suitable for the portable monitor.

我们研制了一种采用氧化锡半导体气味传感器的固定式动态无创监测仪。这是用来监测残疾老人的排泄物的。本文介绍了一种便携式便携式尿失禁监测仪的试验应用。2.材料和方法由氧化锡半导体传感器、气泵、信号处理电路、存储和显示器件(PC：NEC9800NX)组成的系统。1)氧化锡半导体气味传感器的改进。固定式监测仪采用TGS2600系列D1，这是一种双面安装式传感器，可实现5V正负0.2V加热电路(AC、DC)的恒充电条件。在这次试验中，我们使用了TGS 2400系列M1，这是一种单面安装型传感器。热路由脉冲电压驱动。传感器信号是在加热器电压施加后150毫秒的定时测量的。传感器的外壳是9.2 mm的OUTE…柱直径更大，身高7.8毫米。重量为1.1克2)空气泵隔膜泵，2002G(ASF由Thomas Co.)被利用了。外加电压为DC6V。以350毫升/分钟的速率连续采样空气。3)系统氯乙烯管的顶端放置在尿布和盖子之间的尾骨。使用气泵连续72小时通过管子顶端采样空气。传感器信号由PC机进行处理，结果在CRT上显示。我们使用结果的硬拷贝进行调查。III.结果系统对排尿和排便有反应。排尿时的反应曲线呈尖峰型。4.结论我们采用了一种将信号直接传输到PC机的方法。我们计划使用批量方法，通过这种方法，传感器信号将被连续记录在RAM上，并由PC读取。这种方法将适用于便携类型。脉冲驱动的传感器具有更高的灵敏度，特别是对硫化氢和乙醇气体的灵敏度更高。传感器和泵的驱动功耗很低，适合于便携式监护仪。较少
