Abstract

An inflatable mask with two ocular cavities can seal against a user'"'"'s face by forming an air-tight seal around the periphery of the user'"'"'s eye socket. The sealed air-tight ocular cavity can be pressurized to take ocular measurements. The mask can conform to the contours of a user'"'"'s face by inflating or deflating the mask. In addition, the distance between the user and a medical device (e.g. an optical coherence tomography instrument) can be adjusted by inflating or deflating the mask. Also disclosed herein is an electronic encounter portal and an automated eye examination. Other embodiments are also described.

Claims

1. A mask, comprising:

a distal sheet member having one or more substantially optically transparent sections;

the inflatable member having two cavities therein, wherein the two cavities are generally aligned with the one or more substantially optically transparent sections, wherein the two cavities extend from the rear concaved surface toward the distal sheet member such that the two cavities define two openings on the rear concaved surface;

wherein the rear concaved surface is configured to seal against the first patient'"'"'s face such that the first patient'"'"'s eyes are aligned with the two cavities, so that the rear concaved surface forms seals around a peripheral region of the first patient'"'"'s eye sockets that inhibit flow of fluid into and out of the cavities;

an ocular port providing access to at least one of the two ocular cavities for fluid flow into and out of the at least one of the two ocular cavities; and

an inflation port providing access to inflate the inflatable member.

2. The mask of claim 1, wherein the rear concaved surface is configured to conform to the contours of the first patient'"'"'s face with inflation of the inflatable member via the inflation port.

3. The mask of claim 1, wherein the inflatable member is underinflated, wherein the rear concaved surface is configured to conform to the contours of the first patient'"'"'s face with inflation of the underinflated inflatable member via the inflation port.

4. The mask of claim 1, wherein the rear concaved surface is configured to conform to the contours of the first patient'"'"'s face with application of negative pressure to the inflatable member via the inflation port.

5. The mask of claim 1, further comprising particulate matter disposed within the inflatable member, wherein the particulate matter is configured to pack together with application of negative pressure to the inflatable member via the inflation port, so that the rear concaved surface conforms to the contours of the first patient'"'"'s face.

6. The mask of claim 1, wherein the rear concaved surface is configured to conform to contours of a second patient'"'"'s face, wherein a contour of the second patient'"'"'s face is different from a contour of the first patient'"'"'s face.

8. The mask of claim 1, further comprising a lip extending into at least one of the two cavities from a perimeter of at least one of the two openings, the lip having distal ends curving toward the distal sheet member in a default position, the distal ends configured to move rearwardly such that the lip seals against the user'"'"'s face upon introduction of positive pressure into the at least one of the two cavities.

10. The mask of claim 1, wherein the distal sheet member is configured to interface with a medical device.

11. The mask of claim 10, wherein the medical examination device is an eye exam device.

12. The mask of claim 1, wherein the mask is configured to couple with a docking portion on a medical device.

14. The mask of claim 1, wherein the inflation port and the ocular port are configured to couple with conduit ends on a medical device.

16. The mask of claim 14, wherein the ocular port and the inflation port are configured to couple with the conduit ends on the medical device substantially simultaneously.

73. The mask of claim 1, wherein the mask is deflatable.

31. A mask comprising:

a distal sheet member having one or more substantially optically transparent sections;

a proximal pre-inflated member having a generally rear concaved surface that faces a first patient'"'"'s face when in use, wherein the rear concaved surface is configured to conform to contours of the first patient'"'"'s face;

the pre-inflated member having two cavities therein, wherein the two cavities are generally aligned with the one or more substantially optically transparent sections, wherein the two cavities extend from the distal sheet member to the rear concaved surface such that the two cavities define openings on the rear concaved surface;

wherein the rear concaved surface is configured to seal against the first patient'"'"'s face such that the first patient'"'"'s eyes are aligned with the two cavities, so that the rear concaved surface forms seals around a peripheral region of the first patient'"'"'s eye sockets that inhibit flow of fluid into and out of the two cavities; and

an ocular port providing access to at least one of the two ocular cavities for fluid flow into and out of the at least one of the two ocular cavities.

32. (canceled)

a pump assembly comprising;

one or more conduits;

a pump configured to provide fluid to one or more conduit ends via the one or more conduits; and

a pressure sensor configured to sense a pressure in an ocular cavity formed in an inflatable member of the mask; and

a processor in electronic communication with the pump and the pressure sensor, wherein the processor is configured to;

receive the pressure in the ocular cavity; and

control operation of the pump.
