Abstract: A adjustable clamping device for applying pressure to a puncture site of an artery. The clamping device has a radial arm movably supported on a column which extends from a base. A carrier movably mounted on the end of the arm supports a pressure pad. The radial arm extends in a parallel attitude over the base and may be adjusted vertically upwardly and downwardly in reference to the base and may also be pivoted in reference to the column. Lateral movement of the arm facilitates positioning the pressure pad over the puncture site. A releasable feed mechanism on the arm controls movement of the carrier and thus the pressure pad. With the feed mechanism engaged, rotation of the carrier provides a controlled feeding of the carrier relative to the arm. With the feed mechanism disengaged, the carrier may be rapidly advanced or retracted. Independent locking mechanisms are provided for clamping of the lateral movement of the arm separate from the vertical and pivotal movements.

Abstract: A hemostasis pressure pad band is shown and described including a controllably adjustable band for tightening about a patient's limb and a needle site contacting pad which bears against a needle site at the time of needle removal to prevent bleeding therefrom. The pad includes a pair of cheek formations which define a channel along and in which a graft is positioned prior to needle removal. The channel formation may further include a ridge formation of its base and along its length which further defines side channels for better permitting circulation while engaging the needle site. The pad also includes a notch formation at one end of the channel for accommodating the inclined needle at the needle site prior to its removal.

Abstract: A low inductance probe contains a signal probe shaft having a signal probe point and an adjacent ground conductor or conductive shield for placing on the circuit location which is desired to be measured, a ground probe arm having a ground probe point for placing on a convenient ground location. The ground probe arm is attached to the signal probe shaft by means of a hinge which enable the ground probe arm to rotate between zero and approximately 135 degrees in a compass like fashion. The ground conductor of the signal probe shaft and the ground probe point of the ground probe arm are electrically connected by means of a low inductance ground lead consisting of a monolithic, flexible strand of conductive foil.
