Inflatable medical interfaces and other medical devices, systems, and methods
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.
1. An optical coherence tomography device, the device operable to direct an incident light beam to a subject's eyes and receive a reflected or scattered light beam from the subject's eyes, the device comprising:
a housing comprising a port, the port configured to provide fluid flow into and out of the ophthalmic instrument;
a light source within the housing, the light source configured to direct the incident light beam to the subject's eyes;
an interferometer within the housing, the interferometer configured to produce optical interference using light reflected from the subject's eye;
an optical detector disposed so as to detect said optical interference;
a docking portion configured to receive a mask;
a pressure source configured to interface with the port and adjust a pressure in an ocular cavity between the subject's eye and the mask when the mask is received in the docking portion; the pressure source configured to adjust an amount of air flowing through the port, the pressure source positioned within the housing;
a conduit extending from the pressure source to the port.
2. The device of claim 1 , further comprising a second port positioned on the housing, and a second conduit extending from the pressure source to the second port.
3. The device of claim 1 , further comprising a valve configured to affect flow through the port.
4. The device of claim 3 , wherein the valve is positioned in the conduit.
5. The device of claim 1 , further comprising a pressure sensor.
6. The device of claim 5 , wherein the pressure sensor is positioned in the conduit.
7. The device of claim 1 , further comprising a flow sensor.
8. The device of claim 7 , wherein the flow sensor is positioned in the conduit.
9. The device of claim 1 , wherein the docking portion comprises a slot for receiving the mask.
10. A system comprising:
the device of claim 1 ; and
a mask.
11. The system of claim 10 , wherein the mask comprises:
at least one optically transmissive section; and
a mask port configured to provide fluid flow through the mask,
wherein when the mask is received in the docking portion, the mask port is in fluid communication with the port of the housing.
12. The device of claim 1 , wherein the pressure source is a negative pressure source.
13. The device of claim 1 , further comprising a pressure sensor configured to sense the pressure in the ocular cavity.
14. The device of claim 1 , wherein the conduit is within the housing.
