  • Patent number: 4765316
    Abstract: A portable electro-mechanical system stimulates the human scalp by distributing vacuum and vibration generated by apparatus cooperatively operationally confined within a system helmet. A rigid plastic helmet includes an internal housing region in which a self contained vacuum generating motor is preferably vertically disposed for providing a rigorous vacuum. A resilient vibration distribution pad includes a plurality of individual spaced-apart fingers which extend towards and contact the scalp of the user, and between which a plurality of vacuum distribution voids are defined. A vibrator including a high velocity motor whose shaft is coupled to a rotatable eccentric is mechanically linked to the vibration pad, forcing the vibration fingers emanating integrally from the base portion of the pad to transmit vibration to the user's scalp.

  • Patent number: 4469092
    Abstract: An electro mechanical system for stimulating the human scalp. The system includes a rigid helmet adapted to be placed upon the head of a patient to be treated, which helmet includes an internal pad comprising integral, stimulating finger members which directly contact the scalp of the patient. A vibration motor housed within the helmet communicates mechanically with the pad to gently vibrate same to stimulate the scalp. Remote means for generating a vacuum are inter-connected with the helmet through an elongated vacuum hose, and a vacuum input orifice is defined within the helmet. Preferably the vibration motor is housed within the vacuum inlet orifice, and vacuum is distributed interiorly of the helmet during vibration to stimulate the scalp.
