Abstract: A pressure sensing retractor device and method is provided for measuring orbital compartment pressure of an eye. The device uses nested claw-like retractors where the inner claw retractor is capable of pulling an eyelid of the eye of a patient, and the outer claw retractor is capable of sensing the orbital compartment pressure of the eye. The pressure sensing retractor outputs the force sensor signal as a continuous signal of the orbital compartment pressure of the eye. Embodiments of the invention can be applied towards analysis of orbital compartment syndrome, retrobulbar hemorrhage (RBH), and canthotomy/cantholysis. Unlike applanation tonometry, retractor placement with the retractor provided herein requires no specialized training. Ease of use can help facilitate appropriate clinical decision, especially in environments without immediate access to ophthalmic consultation.

Abstract: The present invention relates to improved packages which include a rigid or semi-rigid tray having a single thermoplastic overwrap comprising a polymeric laminate surrounding the tray and having a front panel and an opposing back panel. The inventive packages also include a continuous seal circumscribing a recessed cavity of the tray which comprises a heat seal formed by heat sealing a portion of the front panel to the peripheral flange of the tray. Advantageously, when the tray is removed from the overwrap, a portion of the first film separates from the laminate and remains peelably sealed to the flange of the tray and thus, may serve as a lidding film for the container. Since the recessed cavity is still covered, the container may then be placed directly in a microwave or conventional oven to thaw and/or cook the food container within the package without first removing the lidding film.
