An apparatus for generating ECG recordings and a method for using the same are disclosed. The apparatus includes a handheld device having four electrodes on an outer surface thereof, the handheld device having an extended configuration and a storage configuration. The apparatus also includes a controller configured to measure signals between the electrodes to provide signals that are used to generate an ECG recording selected from the group consisting of standard lead traces and precordial traces. When the handheld device is in the extended configuration and the first and second electrodes contact a first hand of a patient such that the first and second electrodes contact different locations on the first hand, the third electrode is in contact with a location on the patient's other hand and the fourth electrode contacts a point on the patient's body that depends on the particular trace being measured.

A pen comprising a shaft, a gripping zone, and a measuring device having a sensor configured to measure a force acting on the gripping zone. The pen further comprises a cover in the area of the gripping zone, the cover configured to cover the measuring device.

A combined intraocular pressure (IOP) measuring and eye medication dispensing device may include a first micro-electro-mechanical-system (MEMS) sensor to generate IOP measurements of a living organism's eye; a medication dispensing device to dispense medication into the living organism's eye; a second MEMS micro-dispenser to interface with the medication dispensing device and to control the dispensing of the medication into the living organism's eye; and an analog-to-digital (A-to-D) converter to receive control signals. The A-to-D converter may communicate the control signals to the first MEMS sensor or the second MEMS micro-dispenser; receive the generated IOP measurements from the first MEMS sensor; receive medication dispensing parameters from the second MEMS micro-dispenser or medication dispensing device, and communicate the generated IOP measurements or the medication dispensing parameters. The device may also include a communications interface to receive the control signals from one or more processors in an external control module.
