Abstract

Ocular ultrasound models, and ocular ultrasound training simulators using the same, along with methods of making and using the same, are described.

First claim

What is claimed is:

1. An ocular ultrasound model comprising:
a globe having an anterior section and a posterior section;
a first inner wall and a second inner wall extending from the globe at the posterior section;
a first side wall extending at a first angle from a line tangent to a middle point on a first hemisphere of the globe;
a second side wall extending at a second angle from a line tangent to a middle point on a second hemisphere of the globe;
a bottom wall extending between the two side walls, wherein the first and second inner walls extend from the globe to the bottom wall;
a first ultrasoundable chamber between the first inner wall and the first side wall;
a second ultrasoundable chamber between the second inner wall and the second side wall; and
an optic nerve chamber between the first inner wall and the second inner wall;
wherein the first ultrasoundable chamber and the second ultrasoundable chamber are filled with a gelatinous substance.

2. The ocular ultrasound model of claim 1 , further comprising an enclosed chamber disposed within the anterior section.

3. The ocular ultrasound model of claim 2 , wherein the enclosed chamber is formed from a first arc member and a second arc member, wherein the first arc member is concave and the second arc member is convex, the first arc member having a different length than the second arc member.

4. The ocular ultrasound model of claim 1 , wherein the ocular ultrasound model is translucent.

5. The ocular ultrasound model of claim 1 , wherein the ocular ultrasound model is flexible.

6. The ocular ultrasound model of claim 1 , wherein the first and second inner walls are substantially parallel to each other.

7. The ocular ultrasound model of claim 1 , comprising a plastic material, wherein the globe, the first and second inner walls, the first and second side walls, and the bottom wall all comprise the plastic material.

8. The ocular ultrasound model of claim 1 , further comprising the gelatinous substance in the globe.

9. The ocular ultrasound model of claim 1 , wherein the first angle approximately equals the second angle.

10. The ocular ultrasound model of claim 1 , further comprising a retinal wall extending from a first point on an inner surface of the globe to a space within the globe near a second point on the inner surface, wherein the retinal wall does not cross more than half a width of the globe, the ocular ultrasound model providing a representation under ultrasound of a human eye having a retinal detachment.

11. The ocular ultrasound model of claim 1 , the first and second inner walls defining the optic nerve chamber between the globe and the bottom wall, wherein the optic nerve chamber has a narrower section and a wider section, the ocular ultrasound model providing a representation under ultrasound of a human eye having increased optic nerve diameter.

12. The ocular ultrasound model of claim 1 , further comprising a foreign body wall extending from an inner surface of the globe, the ocular ultrasound model providing a representation under ultrasound of a human eye having an intraocular foreign body.

13. The ocular ultrasound of model of claim 1 , further comprising a speckled area within the globe defined by a curvy wall extending between two points on an inner surface of the globe, wherein the curvy wall crosses over more than half a width of the globe, the ocular ultrasound model providing a representation under ultrasound of a human eye having a vitreous hemorrhage.

14. The ocular ultrasound model of claim 1 , further comprising a speckled area defined by a curvy wall extending from a first point on an inner surface of the globe to a space near, but not touching, a second point on the inner surface, wherein the curvy wall crosses over more than half a width of the globe, the ocular ultrasound model providing a representation under ultrasound of a human eye having a vitreous detachment.

15. The ocular ultrasound model of claim 1 , further comprising a dislocated lens chamber formed in the posterior section of the globe, the ocular ultrasound model providing a representation under ultrasound of a human eye having a dislocated lens.

16. The ocular ultrasound model of claim 15 , further comprising a curvy wall extending from a first point on an inner surface of the globe to a second point on the inner surface of the globe, wherein the curvy wall defines a reduced globe space between the first arc and the curvy wall having a volume less than the volume of a space between the curvy wall and the globe in the posterior section, the ocular ultrasound model providing a representation under ultrasound of a human eye having a ruptured globe.

17. The ocular ultrasound model of claim 1 , further comprising a foreign body wall extending from an inner surface of the globe, and a speckled area within the globe defined by a curvy wall extending between two points on an inner surface of the globe, wherein the curvy wall crosses over more than half a width of the globe, the ocular ultrasound model providing a representation under ultrasound of a human eye having an intraocular foreign body and a vitreous hemorrhage.

18. An ocular ultrasound training simulator comprising:
a representation of a human head having two sockets each configured to receive an ocular ultrasound model; and
an ocular ultrasound model of claim 1 configured to be inserted in at least one of the sockets.

19. An ocular ultrasound model comprising:
a globe having an anterior section and a posterior section, wherein the globe has an inner surface and an outer surface;
either first and second inner walls extending from the globe at the posterior section;
a first arc member within the globe extending between two points on the inner surface, wherein the first arc member comprises an anterior surface and a posterior surface;
a second arc member within the globe extending between two points on the anterior surface of the first arc member;
a first ultrasoundable chamber adjacent to the first inner wall;
a second ultrasoundable chamber adjacent to the second inner wall; and
an optic nerve chamber between the first inner wall and the second inner wall;
wherein the first ultrasoundable chamber and the second ultrasoundable chamber are filled with a gelatinous substance; and
wherein the first arc member and the second arc member define two chambers within the anterior section of the globe.

20. The ocular ultrasound model of claim 19 , wherein one of the first arc member or the second arc member is concentric with the globe.

21. The ocular ultrasound model of claim 19 , wherein the ocular ultrasound model is filled with the gelatinous substance.

22. An ocular ultrasound model comprising:
a substantially spherical globe comprising a first enclosed chamber which provides a representation, upon application of ultrasound waves, of a lens of a human eye, wherein the first enclosed chamber is filled with a gelatinous substance;
a first side wall, a second side wall, a first inner wall, and a second inner wall extending from the globe;
a first ultrasoundable chamber between the first inner wall and the first side wall;
a second ultrasoundable chamber between the second inner wall and the second side wall; and
an optic nerve chamber between the first inner wall and the second inner wall, wherein the optic nerve chamber provides a representation, upon application of ultrasound waves, of an optic nerve of a human eye;
wherein the globe, the first enclosed
