  • Patent number: 4795148
    Abstract: An exercise device for the feet and legs, where the device has foot plates for exercising a supine person's feet; calf squeezers for compressing the calf muscles when the feet are exercised; and a support structure holding the foot plates in a vertical position and the calf squeezers in a horizontal position.Persons in a supine position exert a rocking movement of the foot plates and this rocking movement makes the calf muscles squeeze against the calf squeezer. This squeezing pumps blood out of the deep veins of the calf and prevents stasis of blood and clot formation in the deep veins of the calf.

  • Patent number: 4669722
    Abstract: A pair of foot attachments for performing leg exercises so as to facilitate efficient pumping action of blood from deep leg veins.

  • Patent number: 4568326
    Abstract: An article to be used as an aid in the treatment of epistaxis consisting of a fluid absorbing portion which is pear shaped in cross-section for insertion into a part of the nasal cavity with a semi-rigid handle portion having along one end section a multi-spoked support structure about which the fluid absorbing portion is mounted and maintained in the pear shaped cross section. When inserted into the nasal cavity the pear shaped cross section of the fluid absorbing portion, as maintained by the support structure, provides both essentially uniform pressure for constricting blood flow and localities for aggregation of fibrin to promote blood clotting.
