    • A remote telemetry metering system, includes one or more battery-powered metering units and a central data collection unit, each including a radio transceiver. The central data collection unit transmits a signal including power down time information and transmits instructions, which is received by each metering unit. Each metering unit extracts the power down time information and transmits instructions from the signal and, if appropriate, transmits data in response to the data transmit instructions; this data being collected by the central data collection unit. The metering units then interrupt the power supply to their transceivers for a period of time which is dependent upon the power down time information. The central data collection unit delays, for a slightly longer period of time before transmitting a further signal via its transceiver, at which time the power supply to the transceiver of each metering unit has already been resumed. By allowing the metering units to power down to a quiescent state under the control of the central data collection unit, flexibility is ensured and power consumption minimized.

    • A pad of elastomeric material having a softness of typically no more than about durometer 50 Shore 00. The pad may carry adhesive and/or a housing for adhering the pad to a surface, either manually, or by adhesive tape, or another strap. Such a pad exhibits hemostatic and leak prevention properties against needle puncture holes in the skin or the wall of a hollow medical device. Particularly, hemostasis may be prevented with low pressure application of the pad to the skin. The pad may be previously applied to the skin of the patient or a wall of a medical device such as tubing or a solution bag, and the needle may then penetrate both the pad and the skin or medical device wall, to make a resealable puncture with leakage reduction and hemostasis when the needle is withdrawn.
    • 具有通常不超过约硬度50 Shore 00的柔软度的弹性体材料垫。该垫可以携带粘合剂和/或用于将垫粘合到表面上的手套或粘合带或另一条带的壳体。 这样的垫片对于中空医疗装置的皮肤或壁的针刺孔具有止血和防漏性能。 特别地,可以通过将该垫低压施加到皮肤来防止止血。 垫可以预先施加到患者的皮肤或医疗装置(例如管或溶液袋)的壁上,并且针可以然后穿过垫和皮肤或医疗装置壁两者进行可再密封穿刺, 拔针时泄漏减少和止血。
