Abstract A disposable and adjustable blood vessel clamp for the control and reduction of fluid flow through tubes and vessels especially the flow of blood through blood vessels during surgery is disclosed. The plastic device comprises a base frame having mounted thereon a handle or grip means and an extended arm or extension lever which is sufficiently long to generate tension in a stretched filament or flexible tubing which is pulled along its length and fastened. At the one extremity of the arm is a bifurcated foot having a bisecting slot therein through which the stretched filament can be passed after the filament is looped over the blood vessel. A means for attaching both ends of the filamentary tubing to the handle means is also provided by preferably a spring lever in the handle frame which can be depressed to release the tension on the stretched filament and released to reengage the ends of the tensioned filament or tube. When the flexible tube or filament is pulled by one hand along the extender arm and cradled in the bifurcated foot after being looped over the blood vessel its ends are trapped in the jaws of the spring lever. This cuts off the blood flow until the jaws are opened and the tension reduced by a relaxation of the tension on the stretched filament.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
104 words
An adjustable blood vessel clamp which comprises: a. a base frame having, thereon, on one end a handle means connected by a single extender arm terminated by a bifurcated foot on the opposite end and b. a stretchable filament attachment means interposed between said handle means and said bifurcated foot, c. the said filament attachment means of (b) being a clamp whose jaws are releasable by compression of the handle means and d. a stretchable filament member attached at both ends to the said filament attachment clamp and having its median point pass through the bifurcated foot of the device in substantial attachment thereto.
Claim 2
Dependent Claim

An adjustable blood vessel clamp which comprises: a. a base frame having, thereon, on one end a handle means connected by a single extender arm terminated by a bifurcated foot on the opposite end and b. a stretchable filament attachment means interposed between said handle means and said bifurcated foot, c. the said filament attachment means of (b) being a clamp whose jaws are releasable by compression of the handle means and d. a stretchable filament member attached at both ends to the said filament attachment clamp and having its median point pass through the bifurcated foot of the device in substantial attachment thereto.
Claim 3
Independent Claim
59 words
A method for reducing the flow of blood through blood vessels which comprises: a. looping a filamentary clamping means over the vessel b. inserting the ends of the looped filament between the bifurcated foot of a clamp of claim (1.) and c. pulling the filamentary clamping means taut by continuous adjustable attachment to the handle of the said clamp.
