摘要： A hematocrit measuring instrument of the type which determines hematocrit of blood from the electrical resistivity of the blood is provided with a blood resistivity measurement device, an ultrafilter for filtering a part of the plasma from the blood, a filtrate resistivity measurement device for measuring the resistivity of the filtrate from the ultrafilter and an arithmetic circuit for calculating the hematocrit of the blood from the resistivities of the blood and the filtrate. The hematocrit measuring instrument is connected into a circulatory path for the blood outside of the patient's body and continuously measures the hematocrit of the blood from the resistivity of the blood and the resistivity of the filtrate from the ultrafilter.

摘要： A telemetering intracranial pressure transducer comprises an airtight casing member housing a pressure-electric transducer for detecting an intracranial pressure, a pressure-receiving layer disposed in contact with the pressure-electric transducer and in pressed engagement with the dura under the skull, and a transmitting circuit for transmitting an output signal indicative of the intracranial pressure through a transmitting antenna. The transmitting circuit includes a telemetering transmission circuit, a microbattery and a switch for switching on and off the microbattery. The transducer thus constructed is entirely embedded below the head, dispensing with external wires or a receiving coil on the head, and detects an intracranial pressure safely and accurately without confining or disturbing the activities of a testee.
摘要翻译：遥测颅内压变换器包括容纳用于检测颅内压的压力电传感器的气密性壳体构件，与压力电变换器接触设置的压力接收层并与头骨下方的硬脑膜进行压力接合，用于通过发送天线发送表示颅内压的输出信号的电路。发射电路包括遥测发射电路，微电池和用于接通和断开微电池的开关。如此构造的传感器完全嵌入头部，在头部分配外部电线或接收线圈，并且安全且准确地检测颅内压，而不会限制或扰乱被测者的活动。
