Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
185 words
An artery clamp for applying pressure to an artery of a member of a patient, comprising; a base; a column extending upwardly and fixedly attached to the base; an arm extending from said column adapted to overlie the member of the patient resting on said base; a carrier including a rod, said arm provided with a configured guide opening mated to said rod and permitting vertical sliding axial movement only of said rod whereby the carrier is adjustably mounted to the arm overlying said member and adjustably movable toward and away from said member; a pressure pad on a lower end of said rod to be moved by said rod into engagement with said member; an adjusting mechanism mounted to said arm and in engagement with said rod for controlling adjustment of said carrier relative to said arm; said adjusting mechanism having mutually exclusive dual adjusting functions including a first adjusting function for controlled adjustment of the pressure pad toward and away from the member and a second adjustment function manually engageable to release and first adjustment and provide rapid adjustment of the pressure pad.
Claim 2
Dependent Claim
185 words
An artery clamp for applying pressure to an artery of a member of a patient, comprising; a base; a column extending upwardly and fixedly attached to the base; an arm extending from said column adapted to overlie the member of the patient resting on said base; a carrier including a rod, said arm provided with a configured guide opening mated to said rod and permitting vertical sliding axial movement only of said rod whereby the carrier is adjustably mounted to the arm overlying said member and adjustably movable toward and away from said member; a pressure pad on a lower end of said rod to be moved by said rod into engagement with said member; an adjusting mechanism mounted to said arm and in engagement with said rod for controlling adjustment of said carrier relative to said arm; said adjusting mechanism having mutually exclusive dual adjusting functions including a first adjusting function for controlled adjustment of the pressure pad toward and away from the member and a second adjustment function manually engageable to release and first adjustment and provide rapid adjustment of the pressure pad.
Claim 3
Dependent Claim
56 words
An artery clamp as defined in claim 1, wherein; the rod has a threaded shaft and the first adjustment function is provided by a female threaded nut having a threaded portion, said nut movably mounted on said arm and a biasing member urging said threaded portion of said nut into threadable engagement with said threaded shaft.
Claim 4
Dependent Claim
86 words
An artery clamp as defined in claim 2, wherein; the nut is pivotally mounted for pivoting the nut around a pivot point positioned above said threaded portion which is pivoted upwardly and inwardly toward said shaft to achieve engagement with said shaft and is pivoted downwardly and outwardly away from said shaft to achieve dis-engagement with said shaft thereby permitting a downward force on the carrier to effect release of the nut and whereby an upward force tightens the engagement of the nut with the shaft.
Claim 5
Dependent Claim
54 words
An artery clamp as defined in claim 3, wherein; said biasing is provided by a spring member urging pivoting movement of said nut toward said shaft; and, a lever extends from said nut, said lever manually engageable to force pivoting of said nut away from said shaft and out of engagement with said shaft.
Claim 6
Dependent Claim
24 words
An artery clamp as defined in claim 4, further including; a carriage movably mounted on the column; said arm movably mounted on the carriage.
Claim 7
Dependent Claim
30 words
An artery clamp as defined in claim 5, further including; a carriage clamping mechanism; an arm clamping mechanism; and, said carriage clamping mechanism and said arm clamping mechanism separately operable.
Claim 8
Dependent Claim
102 words
An artery clamp as defined in claim 3 wherein the configured guide opening is provided by a slot that extends vertically through the arm, said slot having an enlarged end that is cylindrically shaped with a diameter greater than the remainder of the slot width and mated to the diameter of the shaft whereby the shaft is confined for axial movement only through the configured end of the slot, said nut mounted in the slot of the arm and said threaded portion adapted for pivotal movement into said end of the slot and into engagement with the threaded shaft of said rod.
