Abstract: Disclosed is a toy having a head, a torso, a pair of forelimbs and a pair of hindlimbs to represent a life form. The toy is a 3-D, hollow article, which is made up of a sculptured front member and a rear cover. The interior of the 10 toy has a hollow member to provide a variable volume to contain a fluid. The hollow member may be a deformable bag or a cylinder-plunger assembly. The cylinder-plunger assembly may be joined to a connector and a tube in leak-proof fluid communication. A first end of the connector is exposed to the exterior. The toy is useful for demonstrating a medical treatment or procedure involving infusing, withdrawing or transferring a fluid, or connecting a feeding or breathing tube during treatment. The toy/deformable bag may represent an organ.

Abstract: Disclosed is a toy (100) having a head (110), a torso (112), a pair of forelimbs (114) and a pair of hindlimbs (116) to represent a life form. The toy (100) is a 3-D, hollow article, which is made up of a sculptured front member (101) and a rear cover (102). The interior of the 10 toy has a hollow member to provide a variable volume to contain a fluid. The hollow member may be a deformable bag (600) or a cylinder-plunger assembly (170). The cylinder-plunger assembly may be joined to a connector (150) and a tube (180) in leak-proof fluid communication. A first end (152) of the connector is exposed to the exterior. The toy (100) is useful for demonstrating a medical treatment or procedure involving infusing, withdrawing or transferring a fluid, or connecting a feeding or breathing tube during treatment. The toy/deformable bag may represent an organ.
