    Abstract: A method and apparatus for testing the vacuum level in sealed containers includes a support for the container having an accelerometer attached thereto. The container and support is accelerated by an impacting hammer to cause hydrodynamic oscillations of the contents in the container which in turn are transmitted to and sensed by the accelerometer. If the vacuum level in the container is insufficient, the oscillations are damped and if the vacuum level is sufficient the container contents freely oscillate to produce vibrating oscillations in the container support. The accelerometer produces signals having characteristics correlated to the vibrating oscillations and the containers are accepted or rejected in response to the accelerometer signals.

    Abstract: A catheter placement unit adapted to advance a catheter in a sterile state comprising a catheter having a hub, a concentric needle and hub, a sheath, and a catheter container adapted to enclose a relatively long catheter and being adapted to advance the catheter from the container through the needle and sheath without exposing the catheter. The container in its preferred form is constructed of two halves which snap together to enclose the catheter, and snap apart to expose the catheter. The halves are relatively rotatable, and one half has two concentric walls, the outer wall providing frictional force on the catheter coiled therein, and causing the catheter to advance from the container when the said half is rotated relative to the remaining half.

    Abstract: A safety closure insertable within the neck of a container and depending a short distance into the container to be used in conjunction with a dropper-dispenser for dispensing liquids from the container. The safety closure is sealed to the container with a flange compressed by the container, the closure having sidewalls depending from said flange along the neck of the container and terminating in a bottom opening and a movable closure element urged into a closed position by spring action.
