    • The arterial CO2 monitor and closed loop controller for use with a ventilator monitors a patient's breath and determines PaCO2 based upon a determination of a deadspace ratio, which is the ratio of the alveolar deadspace to alveolar tidal volume. The method generally comprises the steps of continuously monitoring measurable parameters of a patient's breath; obtaining an input value of PaCO2 from a blood sample of the patient and using the patient's breath parameters and the input value to calculate the deadspace ratio; and continuously determining PaCO2 based on the assumption that the deadspace ratio subsequently remains constant. Decision rules obtained from other measurable data are preferably also used to identify the onset of changes in the deadspace ratio, and a new deadspace ratio is then determined from the patient's breath parameters and further input value of PaCO2 from the patient's blood sample.
    • 与呼吸机一起使用的动脉CO2监测器和闭环控制器监测患者的呼吸,并且基于空洞比(其是肺泡死区与肺泡潮气量的比率)的确定来确定PaCO2。 该方法通常包括以下步骤:连续监测患者呼吸的可测量参数; 从患者的血液样本获得PaCO2的输入值,并使用患者的呼吸参数和输入值来计算死空比; 并且基于以下假设,连续地确定PaCO2:空位比随后保持恒定。 从其他可测量数据获得的判定规则优选也用于识别死空间比率变化的开始,然后根据患者的呼吸参数和来自患者血液样本的PaCO2的进一步输入值确定新的空穴比。

    • A drug infusion pump having a drive system including a drive motor (49), a worm gear (53) on the output shaft of said motor, a worm wheel (55) meshing with said worm gear (53) and constructed to drive an output reduction gear (60) and clutch means (62) associated with said output gear (60) for disengaging drive to a drive head (61) engaged by a drive belt (83) which is permanently connected to a syringe actuator (7) to cause controlled infusion of the contents of a syringe under the control of a central control system including a microprocessor (20) and programmable memory means (21 and 23) which determine the manner in which the infusion is performed. A syringe clamping arm (5) is associated with a potentiometer (24) which provides to the controller diameter information regarding the syringe. The programmable memory means (23) includes data relating to one or more standard syringe sizes to enable automatic operation on insertion of a standard syringe. In the event that a non-standard syringe is to be used, the infusion pump may be simply programmed to allow such non-standard syringes to be used.

    • A process for producing a shaped metallic article includes the steps of melting a metal alloy, reducing the temperature of the molten metal to the liquidus temperature, casting the molten metal at the liquidus temperature into a mould and solidifying the molten metal to obtain a feedstock material. The feedstock material is subsequently heated to a temperature between the liquidus and solidus temperatures to produce a self-supporting thixotropic material which is then formed to the desired shape. Casting the feedstock material from a melt at substantially the liquidus temperature produces a microstructure that is especially suitable for subsequent forming of the thixotropic material and this allows use of slower forming speeds and lower forming pressure during the forming step.
    • 一种成形金属制品的制造方法包括熔融金属合金,将熔融金属的温度降低至液相线温度的步骤,将液相线温度下的熔融金属浇注到模具中并固化熔融金属以获得原料 。 随后将原料材料加热至液相线和固相线温度之间的温度,以产生自支撑触变材料,然后将其形成为所需形状。 基本上在液相线温度下从熔体铸造原材料产生特别适用于随后形成触变材料的微结构,并且这允许在成形步骤期间使用较慢的成形速度和较低的成形压力。
