Training manikin for cardio-pulmonary resuscitation

A training manikin for use in teaching students to perform cardio-pulmonary resuscitation includes a head, a neck, and a torso molded integrally of a resilient material allowing flexure of the neck and providing realistic resistance to compression of the torso in simulating external heart massage. A tubular airway passage includes a restrictor and can receive obstructors. A cavity in the torso holds a smaller, infant-size similar manikin. The manikin may have a tough watertight skin surrounding a core of resilient microporous foam of lesser density.

The bracket 6 of the rod holder 2 is constructed of substantially resiliently flexible material and has four slots 24, 26, 28 and 30 in the rim 18 thereof, which depend to points 37 substantially contiguous to the base plate 4, so that the bracket is divided into pairs of relatively resiliently displaceable body portions 38, 40, 42, 44, and 46. The walls 36 of the body portions have successive pairs of part annular collar sections 34 therein, which define successively smaller clamping rings 48, with nips 50 therebetween, as the slots depend toward the plate 4. As a result, when a rod 96 is impaled in the V-shaped kerf of a slot, it can seek that ring 48 which will grip it against dislodgement, when the caduceus-like clamps 32 at the walls of the body portions, relax about the rod.

In a prosthetic foot constructed to store strain energy as the foot reacts to the load of the amputee's body during walking, running, jumping, etc., and then to release the stored energy to create foot lift and thrust which complements the user's natural stride, a monolithic cantilever beam made of a hardened polymer is provided as the keel of the foot with an ankle attachment fitting for connection to a standard upper prosthesis. A flexible foamed polymer is molded about the keel, in the shape of a natural foot, to transfer horizontal loads to the keel and to serve as a cosmetic cover.
