Patent number: 5505623Abstract: An anatomical display apparatus includes a three-dimensional model simulating at least a portion of a human or animal body and within which is located a body part, region, tissue and/or organ of interest. A plurality of images of the body part, each showing the body part in a different state or condition such, for example, as before, during and/or after a therapeutic treatment, are carried on a movable support disposed within the model. The support is selectively movable under user manipulation or control so as to transport a selected one of the plural images into suitable juxtaposition with an opening or passageway defined in and through the model and thereby permit an observer located externally of the model to view the selected image within the model through the passageway.Type: GrantFiled: January 12, 1994Date of Patent: April 9, 1996Inventors: Milton Chernack, Daniel Stool, Therese Santoro

Patent number: 5380207Abstract: A kit for practicing ophthalmic suturing technique simulates the anterior portion of a human eye having a torn iris. The kit comprises a workpiece having a planar board with two elastic bands attached at their ends to the board in spaced, parallel relation to one another whereby the lengths of the bands between their ends may be moved with respect to the board. A transparent dome is attached at its perimeter to the board in covering, centered relation to the elastic bands. The dome includes first and second, axially aligned holes formed therethrough with the common axis of the holes extending transversely to the longitudinal extensions of the bands. The space between the elastic bands represents a tear in the iris with the transparent dome representing the anterior portion of an eye. A length of simulated suture is manipulated through the holes in the dome to close the space between the bands using a suture handling tool in the shape of a hooked crochet needle.Type: GrantFiled: December 27, 1993Date of Patent: January 10, 1995Inventor: Steven B.

Patent number: 5320535Abstract: A mannequin head for use in make-up practice instead of a human body. The mannequin head has at least one human-face-like face section either on the rear or front surface thereof. With the single mannequin head of this invention, a variety of make-up practice can be done. With this single mannequin of this invention, the make-up practice can be effectively done and a user can have an economical benefits.Type: GrantFiled: April 5, 1993Date of Patent: June 14, 1994Inventor: Byueng D.

Patent number: 5320529Abstract: An apparatus and method for locating and surgically positioning a hole for an implant and holder in a jawbone of a patient includes constructing a model of a jawbone. A structure is located within the model depicting variations in density within the jawbone. A hole is drilled into the model based on the location of the structure. A rod is placed into the hole and a guide template is fabricated around the model which forms a bore around the rod. The guide template is placed onto the jawbone of the patient and a hole is drilled through the bore into the jawbone to make a hole in the jawbone along the same path as the hole in the model for receiving the implant and holder.Type: GrantFiled: September 9, 1992Date of Patent: June 14, 1994Assignee: Howard C. WeitzmanInventor: Daniel G. Pompa

Patent number: 5259765Abstract: The present invention is a biofidelic manikin neck comprising a butyl rubber beam inserted between an aluminum base and an aluminum top, with a stainless steel cable assembly in the middle of the beam connecting the top to the base. In a first preferred embodiment of the present invention, a pivot joint is bolted to a lug in the neck top. The joint is attached to a head mounting plate to provide head nodding action. An outer cylinder, comprised of a thick sheet of butyl rubber attached vertically around the head mounting plate and the neck base, allows the head moment to respond to the angle between the head and the torso. A second preferred embodiment of the present invention uses a torsion release swivel joint instead of a pivot joint, and uses additional strips of butyl rubber to stiffen the neck response. A third preferred embodiment uses a rectangular inner beam, and a roughly oval-shaped outer support structure.Type: GrantFiled: October 14, 1992Date of Patent: November 9, 1993Assignee: Simula Inc.Inventor: Marvin K. Richards

Patent number: 5238409Abstract: A valve means (1) is disclosed for use in a teaching manikin to simulate an open and closed airway of the human throat. The valve means comprises a section with a hollow passage and two end openings. A first opening fits onto a manikin head and a second opening seats on a sealing surface. When the head is tilted back the valve means (1) lifts to open the second end to permit the flow of air.Type: GrantFiled: December 10, 1992Date of Patent: August 24, 1993Assignee: Actar Airforce Inc.Inventors: Richard A. Brault, Dianne B. Croteau
