Apparatus And Method Of Use For An Adjustable Radial And Ulnar Compression Wristband

Abstract

An adjustable radial and ulnar vascular compression wristband and its method of use assists in achieving partial or full occlusion of a blood vessel to achieve patent hemostasis when applied to a patient's wrist during or following a medical procedure. At least two adjustably inflatable non-adjacent balloons on the wristband apply preferential compression to portions of the circumference of the wrist, including in particular those portions overlying the ulnar and radial arteries.

AI Technical Summary

Benefits of technology

The invention is an adjustable compression wristband that can be used to partially or fully occlude blood flow through the radial and ulnar arteries while maintaining blood flow through the veins. The device can be quickly attached and detached from the patient's wrist and provides both visual and physical access to the puncture site. The device can also be adjusted in small increments for fine adjustments in external compression.

Problems solved by technology

Although many compression devices are available for compression of the radial artery there are none known to the inventor that can also simultaneously provide compression of the ulnar artery, which are available to clinicians.

Anecdotal evidence suggests that this is an undesirable feature if the deflation is excessive, at least when patients on which it is deployed have been administered anti-coagulation medications and / or are hypertensive, both of which are not-uncommon occurrences in cardiac catheterization patients.

Of these mechanical devices, only the Niemeyer devices enable easy adjustment, and none feature any compression means to provide simultaneous compression over the ulnar artery during radial artery compression.
