An improved training doll for prospective mothers, sisters, child attendants and the like is provided which includes a life-like torso having the approximate weight, size and appearance of a baby, preferably a newborn infant. The torso has arms and legs articulated to it and including fold lines. The arms and legs are also of the proper approximate size, weight and appearance, to simulate a baby and include means in the form of surface patches for restricting movements thereof to life-like movement directions. Thus, the knees may have patch knee caps and the arms may have elbow patches. The head is also of the approximate size, weight and appearance of a baby and is connected to the torso by a weak preferably tube-like neck which permits the head to freely flop forwardly and rearwardly. This can be accomplished by pinching the neck transversely, as by a sew line, at about the junction with the torso. A transverse fold line may also be in the torso at about the midline and the doll preferably is hollow and filled with weighting material such as sand, which preferably can be added and removed to control the doll's weight. The head may include a nipple-gripping opening simulating a mouth. The doll is simple, durable and effective to train proper handling, care and feeding of infants.

A device for simulating the pressure readings obtained from the arm of a living subject whose blood pressure levels are being determined by an oscillometric blood pressure monitor, includes a pulse pressure chamber for generating pressure pulses at a rate equivalent to a preselected pulse rate. The input to the pressure chamber is attached to the pressure cuff of the monitor and the output is connected to the pressure transducer of the monitor. In order to balance the pressure across the chamber and to apply the full cuff pressure to the monitor transducer, a normally-open valve is connected across the pressure chamber. This valve, however, is closed when the chamber creates a pressure pulse so that the pulse is added to the applied cuff pressure at the monitor transducer. A processor generates electrical signals that control the amplitude of the pressure pulses created by the chamber, depending on preselected values for simulated systolic, mean arterial and diastolic pressures.

A four pivot linkage to simulate head/neck kinematics. The linkage has a ch-roll link which rotates about a first pivot fixed in an upper body and which secures the lower end of a neck link in a second pivot. The upper end of the neck link is secured in a third pivot fixed in a yaw-pitch link which in turn articulates about a fourth pivot fixed in a head.

Improved artificial palate for use in dynamic palatographical speech researches and improvements in the method of fabricating such artificial palate are provided. The artificial palate comprises a shell body mold-formed with an electrically insulative plastic material in conformity with individual user's palate. A flexible insulative circuit board includes a plurality of sensing electrodes provided in the board over the area thereof and lead wires printed on both surfaces of the board for connecting the respective electrodes to terminals arranged on both surfaces of the board adjacent an edge thereof. The circuit board is embedded in the shell body exposing the sensing electrodes on the inner surface of the body to be in contact with user's tongue during the use. Insulation coated wires connect the electrode terminals to the exterior and form means for mounting the artificial palate in user's mouth when embedded in the plastic material contiguous to the shell body. In the fabricating method, the circuit board is preliminarily prepared in different sizes, a proper size of the circuit board is selected to be joined to the mold-formed shell body, and the plastic material is applied over the board to embed it in the body but exposing the sensing electrodes on the tongue contacting surface.

A plastic bone used as a training device or teaching aid for a surgeon for mechanically connecting bone fractures, comprising a plastic molded part, the size and dimension of which approximates that of a human extremity-shaft bone having an internal hollow compartment or cavity which extends past a marrow cavity region at the center of the shaft towards both shaft ends into the region of the spongy structured bone lacunae (spongiosa) and widens. The wall structure of the bone approximately corresponds to the solid or compact wall parts (compacta) of the natural structure in weight, strength and mechanical workability.

An ophthalmological simulation device having means for simulating the parts and operation of a human eye including a photographic diaphragm for simulating the iris and an associated photosensitive system for controlling the operation thereof; a film strip having a series of transparencies of funduscopic eyeground representations thereon and mounted on a film transport which presents successive eyegrounds to the retinal position in the eye for viewing through the iris aperture or pupil with a conventional ophthalmoscope; and a screen disposed behind the film to backlight the eyegrounds by reflecting the probing light and thus create the effect of an actual ophthalmological examination. A bilateral arrangement is mounted in a manikin head and a system for simulating the use of mydriatic fluid to dilate the pupil for a given period during examination is also presented.
摘要:
A leg for a medical training dummy comprising a metallic simulated leg bone around which is molded an integral skin foam. The leg bone member includes a hinge for simulating a broken leg. Skinning of the foam against the hinge surface is prevented by wrapping the hinge with a relatively soft foam prior to casting. The hinge includes detents for holding the leg in either its broken or unbroken state.

The main structure of the neck component of a test dummy simulating a human body is a synthetic rubber cylinder connected to the head and upper thorax of the dummy and having a slit in the front upper part thereof and a cavity in the lower central part thereof whereby the neck component deflects asymmetrically in forward and rearward tilting of the head and neck due to crash impact forces thereby to simulate closely the behavior of the human neck under the same impact forces. For refinement of this simulative characteristic, prestressed tension members may be stretched on the left and right sides of the main structure between the upper and lower ends thereof.

A device for use in teaching first aid comprises a panel with a plurality of elements thereon which are shaped in accordance with the outline of parts of the human body. Some of the elements are movable in the manner in which the parts of the body they represent are moved during first aid. The elements are suitably planar, some may overlap and movable elements may be coupled. The elements can be movable parallel to the panel, but in another form they can be mounted to fold up from the panel.
