Abstract

A compression device is used to increase intra-luminal pressure within the upper esophageal sphincter of a patient in order relieve an impact of an abnormal or defective upper esophageal sphincter anatomy, physiology, or functionality. In one implementation, the compression device is used in conjunction with an external pressure sensing device to determine the external pressure that is to be applied to the cricoid for a specific patient. The compression device can be a means for the management and/or treatment of abnormal upper esophageal sphincter functionality, or a means for strengthening an esophageal sphincter of a subject, or a means for curing esophageal reflux disease of a subject, or a means for improving vocal function in a subject, or a means for managing lung aspiration, or a means for applying cricoid pressure during anesthesia intubation, or a means for stabilizing body structures such as during medical imaging or radiation treatment.

Claims

1. A compression device for reducing pharyngeal reflux in a subject, the compression device comprising:

a frame;

a clasp;

a strap having a first end section attached to the frame and an opposite second end section attached to the clasp, a length of the strap between the first end section and the second end section being adjustable; and

a cushion disposed on the frame, wherein the clasp is configured to engage at least a portion of the frame, such that the clasp fastens the strap to the frame to position the cushion over a cricoid of the subject and to apply a predetermined amount of pressure to the cricoid in order to reduce pharyngeal reflux in the subject while allowing the subject to open an upper esophageal sphincter of the subject for other physiological events;

an adjustment mechanism for moving the cushion toward or away from the frame, wherein the adjustment mechanism comprises a plate and a position adjustor movably attached to the plate, the position adjustor being located on a first side of the frame, the plate having a first surface and an opposite second surface, the first surface of the plate being attached to the cushion, the second surface of the plate being in contact with a second side of the frame; and

wherein the clasp is configured to unfasten the strap from the frame and to refasten the strap to the frame to reapply the predetermined amount of pressure to the cricoid.

2. The compression device of claim 1 wherein:

the adjustment mechanism varies curvature of the frame when moving the cushion toward or away from the frame.

3. The compression device of claim 1 wherein:

the cushion is removably attached to the first surface of the plate using a fastener material.

4. The compression device of claim 1 wherein:

the position adjustor is rotatable with respect to the plate such that rotation of the position adjustor in a first direction moves the cushion toward the frame and rotation of the position adjustor in a second direction moves the cushion away from the frame.

5. The compression device of claim 4 wherein:

one of the position adjustor and the plate includes an internally threaded hole,

the other of the position adjustor and the plate includes an externally threaded post, and

the internally threaded hole engages the externally threaded post for translation of the position adjustor relative to the plate.

6. The compression device of claim 1 wherein:

the first end section of the strap is looped through a slot of the frame for attaching the first end section of the strap to the frame, and

an amount of the strap looped through the slot of the frame can be varied by using a fastener material that can removably engage the strap to adjust the length of the strap between the first end section and the second end section of the strap.

7. The compression device of claim 1 wherein:

the second end section of the strap is looped through a slot of the clasp for securing the second end section of the strap to the frame.

8. The compression device of claim 1 wherein:

the first end section of the strap is removably attached to the frame.
