    • A system and method are disclosed for regulating drilling fluid pressure in a drilling fluid circulation system. In one embodiment, a drilling fluid circulation system includes a processor (110) connected to a pressure relief device (104), which is connected to piping between a discharge of a drilling fluid pump (30) and an inlet of a drill string (31). The processor receives pressure measurement signals representative of a pressure of the drilling fluid in the piping and flow parameter signals representative of a flow of the drilling fluid through the piping. From the pressure measurement signals and the flow parameter signals, the processor determines that a target pressure parameter of the drilling fluid in the piping is not satisfied. In response, the processor lowers the pressure of the drilling fluid in the piping until the target pressure parameter is satisfied by at least partially opening the pressure relief device.
    • 公开了一种用于调节钻井液循环系统中的钻井液压力的系统和方法。 在一个实施例中,钻井液循环系统包括连接到压力释放装置(104)的处理器(110),所述压力释放装置连接到钻井流体泵(30)的排放口和钻柱(31)的入口 )。 处理器接收表示管道中钻井流体的压力的压力测量信号和表示通过管道的钻井流体的流量的流量参数信号。 处理器从压力测量信号和流量参数信号中确定管道中钻井液的目标压力参数不满足。 作为响应,处理器通过至少部分地打开压力释放装置来降低管道中钻井液的压力,直到满足目标压力参数。

    • The invention relates to a pneumatic ventricular assist device. The inventive device is designed such that it can be used in any short- or long-term transoperative circulatory support systems including right ventricular assist devices (RVAD), left ventricular assist devices (LVAD) and biventricular assist devices (BIVAD) which can be implanted using a catheter or which take the form of extracorporeal devices. The device consists of a smooth pumping casing and a disposable pumping unit comprising a pumping bag, two one-way valves and tube connectors. The aforementioned pumping unit has been specially designed in order to enable the continuous, fluid movement of the blood and to limit the surfaces with which the blood comes into contact. Said pumping unit is made from a flexible, elastic material such as silicon. The components can be made economically and reliably by means of injection moulding. Furthermore, the pumping casing and the pumping unit comprise complementary characteristics which enable the pumping unit and any associated cannula to be positioned quickly and safely.
    • 本发明涉及一种气动心室辅助装置。 本发明的装置被设计成使得其可以用于任何短期或长期的跨循环支持系统,包括右心室辅助装置(RVAD),左心室辅助装置(LVAD)和可植入的双心室辅助装置(BIVAD) 使用导管或采取体外器材的形式。 该装置由平滑泵送壳体和一次性泵送单元组成,其包括泵送袋,两个单向阀和管连接器。 上述泵送单元是专门设计的,以便能够使血液连续流动地运动并限制血液接触的表面。 所述泵送单元由诸如硅的柔性弹性材料制成。 这些部件可以通过注塑成型而经济可靠。 此外,泵送壳体和泵送单元包括使泵送单元和任何相关套管快速和安全地定位的互补特性。
