For use with the human eye, especially, there is provided a relatively narrow, split, flexible partial ring adapted to fit against the portion of the eyeball behind the upper and lower eyelids. The corneal opening is of an extent so that despite normal excursions of the cornea, the cornea does not substantially contact the ring. The split ring is formed of highly flexible material so as to permit a substantially universal fit and at the same time exert minimal effect on the physiological parameters being measured. A sensor or other device is located on a widened portion of the carrier in contact with the palpebral conjunctiva. A conductor or other transmission device may lead from the device through a projection, preferably integral with the ring, and extending beyond the eyelids. The device carrier is a split ring and relies upon its shape and self-resiliency in order to maintain its position within the eye.

A tool for applying a membrane on a small upstanding post like device, which tool incorporates a housing with means for securing the membrane across the top of the post with additional means disposed opposite the post for holding the membrane against the post and urging it down the side of the post, the housing being closeable to serve as a shipping container and a calibration cell for the device to be membraned with means to secure the post captive with little or no chance of its falling into a non-sterile environment.
