Adjustable Ratcheting Vascular Compression Device and Method of Use

摘要

A ratcheting adjustable vascular compression device assists in achieving partial or full occlusion of a blood vessel when applied to a patient's limb, during or following a medical procedure. During deployment, a compression pad on the device applies preferential compression to at least one portion of the circumference of the limb. Further, securement, adjustment and rapid release of the device are all enabled by an alternate ratcheting mechanism that enables gradual adjustments to be made to the tightness and thus to the compression applied without releasing the device, so as to permit patent blood flow through blood vessels in the limb during the compression period.

主权项

1. An adjustable ratcheting vascular compression device placed onto a patient for partially or completely occluding blood flow in a blood vessel in a limb of the patient by adjustably applying preferential compression to said vessel, the device including:
a housing; a compression pad located on the underside of the housing; a flexible strap connected to a side of the housing; threads placed in at least two rows on the top surface of the strap; at least two independently actuated levers, each having a pawl on its underside for engaging with the threads, and attached to the interior of the housing by a hinge, the hinge having flexion in the manner of a spring.
