Abstract: 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.

The cranium part is provided in opposite side faces thereof with cavities serving as bearing surfaces. A mandible part has top faces adapted to cooperate with said bearing surfaces and form a joint for movement of the mandible part, according to several degrees of freedom. Further, there are provided a hyoid part, a sternum part (41), a pair of clavicle parts coupled with said sternum part by universal couplings as well as a pair of scapula parts coupled with a respective clavicle part by universal couplings, the aforementioned parts being interconnected by a plurality of resilient members, arranged in pairs, which simulate the muscle functions.

Abstract: An ear examination simulator unit for use by parents, children and health care professionals to recognize ear disorders in children includes an ear structure simulator module that is mounted within a head portion of a furry racoon or the like animal facsimile. The ear structure simulator module includes a tube body having orifices defined in ends thereof for receiving an otoscope or other examination tool. Mounted within the tube portion is a semi-translucent membrane and a photographic slide depicting an eardrum in normal or various diseased states. A source of illumination provides light which is distributed by the membrane in order to provide back lighting of the images on the photograpic slide. In addition, the membrane may be textured and colored so as to simulate a human eardrum in its healthy state. The plush toy provides comfort to the child during painful bouts of ear infections and during ear surgery.

Abstract: A mannequin for use as a tool in demonstrating a variety of hair styling techniques such as hair cutting, permanent waving, blending, texturizing and the like includes a simulated human head having a skull, scalp, and human hair attached to the scalp. The hair is of a length and thickness approximating that of an individual of a prescribed sex, size, and type. In a preferred embodiment as used for demonstrating hair cutting techniques, a plurality of variously colored line diagrams are applied to the hair to defined a plurality of cutting lines to be followed to accomplish a plurality of prescribed hair styles.

Abstract: A psychotherapy device comprising a body member, a pair of arms, legs, and a head connected to the body member wherein said pyschotherapy device is in the general configuration of a child-like human figure. The head includes a pair of expressionless eyes and nose which are permanently affixed to the face and means are connected to the face adjacent to and generally below each of the permanent eyes for releasably receiving indicia of tears wherein during pyschotherapy of a child patient, the patient may be invited to apply or remove tears to reflect a current or past metal state.

Abstract: A cranium is firstly produced form an epoxy resin, whose thickness is adapted so that the compressive strength at a given point is the same as at the corresponding point of a real cranium. This is followed by the fitting of the soft parts, i.e. the brain, eyeballs, flats of the ear and nasal pyramid. These members are made from a silicone to which a variable quantity of oil has been added to ensure that their hardness is the same as that of the corresponding real organs. The cranium is then placed on a support permitting the correct orientation thereof in the mould where the skin is cast.

Abstract: A modeling arrangement for an anatomical organ is provided with a plurality of substructure models corresponding to predetermined substructures of the anatomical organ. Such substructures may include representations of organs, volumes, vessels, and fluids which assume predetermined shapes with the anatomical organ being modeled. The arrangement is provided with one or more members which define the surface of the anatomical organ being modeled; the members being couplable to a base member. Preferably, all of the members, including the base member, which support the substructures are formed of a transparent material, preferably one of the type marketed under the Plexiglas trademark. The modeling arrangement may be used in conjunction with written instructions to form a self-learning system which is particularly useful for students of anatomy. In one highly advantageous embodiment of the invention, a biological brain, particularly the fore-brain portion, is represented by the inventive modeling scheme.

The head portion comprises partial bodies corresponding to mean data of test persons with respect to dimensions and relative positions. The partial bodies comprise regular geometric bodies calibrated with respect to sound reflexion, diffraction and resonance behavior to define a reproducible artificial-head transmission function related to the outer geometric configuration of the construction.

Abstract: A new use of an elastomeric material to which a stitchable covering is laminated. More specifically a thin knitted fabric may be laminated to an elastomeric material, optionally a foamed or porous material. Other materials are contemplated. In addition, the invention is directed to forms over which the simulated skin may be placed to reproduce the curvature of the human anatomy. One form has a varying curvature but is essentially square. The various curved portions simulated various curved portions of the skin that would be found on the abdomen, thigh, arm, chest or scalp. Another form is a mannequin simulating the face of a patient and which optionally has means for securing the simulated skin to the mannequin in a life-like configuration which include a simulated mouth and simulated eyes. These in turn assist in anchoring the simulated skin to the mannequin and also provide realistic guidelines for surgical practice.
