Abstract: A container has an upper fluid receiving portion and a lower fluid discharge portion which is closed off at its bottom by a closure. In carrying out the method of the invention, a blood sampling from the umbilical cord of a newly born infant is taken by first clamping off a section of the cord. The clamped section is then separated from the main portion of the cord and deposited into the container. One of the clamps is then removed to permit the blood in the cord section to drain into the container. The drained blood is then transferred to a second container, which may comprise a test tube or syringe, through the fluid discharge portion of the container, this being achieved by either causing a needle attached to the container and sealed with a needle cover to penetrate the needle cover as well as the test tube cover, penetrating the closure with a needle if it be a diaphragm or the like or opening a valve at such closure by a mechanical actuation with the nose of a syringe.

Abstract: A liquid meter assembly for collecting, metering and monitoring liquid is disclosed. The assembly comprises a container for collecting the liquid, an electrically powered strain gauge suspension device for supporting the container and for determining the weight of the liquid collected in the container and a handle on the container for interconnecting with the strain gauge suspension device. A length of tubing is attached to the container and adapted for interconnecting with the source of the liquid. A tubing support system is included on the strain gauge suspension device for fixedly supporting the tubing to substantially inhibit influence on weight determination due to any movement thereon. A power supply is included in the assembly for supplying power to the strain gauge suspension device.

Abstract: A thermodilution injectate assembly which includes a length of flexible tubing for introducing fluid from a solution container to the assembly. An insulated container which holds a heat exchange medium and into which is positioned a substantially flat plate heat exchanger. The heat exchanger includes an inlet port and an outlet port and a fluid-flow path therebetween, which path provides a heat exchange relationship between fluid flowing through the path and the heat exchange medium. A dual directional valve is connected to the outlet port of the heat exchanger and to the solution container. A three-ported stopcock is in fluid-flow communication with the dual directional valve. A syringe is connected to a port on the three-ported stopcock and a length of flexible tubing is connected to a port on the three-ported stopcock for delivering the cooled fluid to a patient for monitoring the cardiac output.
