Abstract
Abstract A training mannikin is disclosed for particular use in simulating various normal and abnormal cardiac conditions in the human body. The mannikin resembles in texture and appearance at least the upper portion of the human body, and has in its interior pulse-producing means including plunger means to simulate pulse points, and sound-producing means to simulate heart beat. Selectively interchangeable cam-operated control means are provided to operate the plunger means in a variety of sequence patterns to simulate a number of normal and abnormal cardiac conditions.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
55 words
A training device of the type used in simulating cardiac conditions comprising: a. at least one manikin unit; b. a plurality of push rods within said manikin; and c. cam-operated means within said manikin for operating said push rods in a pre-determined time pattern thereby producing a pulse-like action on the surface of said manikin.
Claim 2
Dependent Claim
55 words
A training device of the type used in simulating cardiac conditions comprising: a. at least one manikin unit; b. a plurality of push rods within said manikin; and c. cam-operated means within said manikin for operating said push rods in a pre-determined time pattern thereby producing a pulse-like action on the surface of said manikin.
Claim 3
Dependent Claim
54 words
A training device as defined in claim 1, wherein said manikin unit comprises a resilient skin, at least one end of said push rods being located adjacent the interior surface of said skin, means for mounting said push rods for limited vertical reciprocation, and cam means for effecting vertical reciprocation of said push rods.
Claim 4
Dependent Claim
24 words
A training device as defined in claim 2, wherein said means for effecting vertical reciprocation of said push rods comprises fluid pressure activated means.
Claim 5
Dependent Claim
84 words
A training device as defined in claim 3, wherein said fluid pressure activated means includes cylinder means associated with the other end of said push rods, said push rods defining piston means within said cylinder, said cam means is rotatable, fluid compression means activated by said cam means, and fluid pressure conducting means communicating said compression means with said cylinder means, whereby rotation of said cam means compresses fluid within said conductor means and effects vertical movement of said push rods within said cylinder.
Claim 6
Dependent Claim
23 words
A training device as defined in claim 4, wherein said fluid compression means comprises a resilient squeeze bulb compressed by said cam means.
Claim 7
Dependent Claim
55 words
A training device as defined in claim 4, wherein said cam means comprises a plurality of cams associated with each of said fluid compression means, each of said cam means being selectively movable from an inoperative position wherein it rotates without activating said compression means, and an operative position wherein it activates said compression means.
Claim 8
Dependent Claim
29 words
A training device as defined in claim 6, further comprising control means for selectively positioning a combination of said plurality of said cam means into their said operative position.
Claim 9
Dependent Claim
25 words
A training device as defined in claim 7, further comprising means for producing audible heart sounds in synchronization with the production of said pulse actions.
Claim 10
Dependent Claim
22 words
A training device as defined in claim 8, further comprising means for effecting simulated breathing movement of said skin of said mannikin.
Claim 11
Dependent Claim
65 words
A training device as defined in claim 2, wherein said means for effecting vertical reciprocation of said push rods includes at least one cam follower member pivotally secured to said push rods, and said cam means is rotatable and operatively associated with said cam follower member, whereby rotation of said cam means pivots said cam follower means and effects vertical reciprocation of said push rods.
Claim 12
Dependent Claim
25 words
A training device as claimed in claim 10, wherein said cam means comprises a plurality of cams each operatively associated with said cam follower means.
Claim 13
Dependent Claim
22 words
A training device as defined in claim 11, further comprising means for producing audible heart sounds in synchronism with said pulse-like action.
Claim 14
Dependent Claim
24 words
A training device as defined in claim 12, further comprising means for producing a simulated breathing action of said skin of said mannikin unit.
Claim 15
Dependent Claim
25 words
A training device as defined in claim 1, wherein said mannikin simulates in texture and appearance at least the Chest portion of a human body.
