An assembly structured to collect medical data from at least one individual, said assembly comprising: - a hand-held device comprising a housing disposable in an operative position relative to the patient, the housing including a handle portion and a head portion, said housing being dimensioned and configured to be held and operated by a single hand of a user, - a sensor assembly disposed on said head portion of the housing and structured to non-invasively and instantly determine the medical data while said housing is in said operative position, - said operative position comprising said housing disposed within a predetermined spaced distance from the patient, - a memory assembly cooperatively structured with said sensor assembly to concurrently store collected medical data of a plurality of patients, said memory assembly being associated with an interface which allows the input of identifying information in respect of said plurality of patients, - a display assembly disposed on said head portion of the housing and structured to view collected medical data, said display assembly being structured and interactively associated with both the sensor assembly and the memory assembly to display medical data which has been just collected from a patient or which has been stored and subsequently accessed from the memory assembly, - a control assembly at least partially disposed on said housing and structured to access any of the medical data stored in said memory assembly, said control assembly being operatively associated with the sensor assembly and the memory assembly and including one or a plurality of operating or control buttons (24, 25) which may be manipulated by the hand and/or fingers or the user which serve to grip and support the handle portion of the housing, the display assembly being activated either independently or automatically by hand manipulation of the control assembly, - a docking station operatively and removably connected to said housing, said docking station including a base portion and an upwardly protruding supporting member which serves to support and facilitate engagement with the housing of the hand-hold device and, - a medical data transmitting assembly operatively associated with the docking station and cooperatively structured with said memory assembly to communicate the medical data maintained in said memory assembly to a remote processing facility, through the data transmitting assembly, the collected data stored in the memory assembly being downloaded to the data transmitting assembly or, transmitted directly to a remote processing facility. -
