    • 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.
    • 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。

    • A blood purification apparatus includes an extracorporeal circulation system, a blood purifier provided in the system for purifying blood by dialysis or filtration through a semipermeable membrane, a circulation blood volume measuring instrument for measuring changes in a circulating blood volume within a patient's body, a control section comprising a memory for storing a program for a pattern of changes in the circulating blood volume during blood purification, the program being matched to the condition of a patient, and a regulator connected to the extracorporeal circulation system and the control section, for controlling the circulating blood volume, the regulator being controlled by the control section on the basis of the circulating blood volume measured during blood purification and the programmed amount. In this apparatus, optimum blood purification is carried out while maintaining the circulating blood volume at a prescribed level.
    • 一种血液净化装置,包括体外循环系统,通过半透膜进行透析或过滤而提供血液净化的血液净化装置,用于测定患者体内的循环血液量的变化的循环血液量测定装置, 该部分包括用于存储用于在血液净化期间循环血液量的变化模式的程序的存储器,该程序与患者的状况相匹配,以及连接到体外循环系统和控制部分的调节器,用于控制 循环血液量,调节器由控制部分根据血液净化期间测量的循环血液量和编程量控制。 在该装置中,在将循环血量保持在规定水平的同时进行最佳的血液净化。
