Patient interface for ophthalmologic diagnostic and interventional procedures
First Claim
Patent Images
1. A system for intercoupling an ophthalmologic interventional system to an eye of a patient, comprising:
- a. a hollow reservoir housing defining an interior volume and having proximal an distal ends, wherein the distal end comprises a eye interface surface configured to be removably and sealably coupled to the eye of the patient, and wherein the proximal end is configured to be mechanically interfaced with the interventional system in a manner that allows for open access to the interior volume for transporting liquids or gases in or out of the interior volume;
b. an optical element fixedly coupled to the hollow reservoir housing and occupying a portion of the interior volume; and
c. a liquid layer formed within the interior volume of the reservoir housing and positioned via one or more loads that include gravitational loads, between the optical element and the eye,wherein the hollow reservoir comprises two parts that may be removably coupled to each other,wherein the two parts are removably coupled to each other using a configuration selected from the group consisting of;
a vacuum coupling interface, an interference fit interface, an electromagnetic coupling interface, and a electromechanically-actuated mechanical interface,wherein the eye interface surface comprises a compliant circumferential seal member, and the seal member comprises two circumferential layers with a vacuum space interposed between the two layers.
