Intraocular pressure applicator
First Claim
1. A device for lowering intraocular pressure in preparation for intraocular surgery comprising a headband adapted to extend around the head of the surgery patient, a single, circular, cup-shaped member attached to said headband and forming a chamber having a movable wall at one end, said chamber forming member having a bellows configuration with said movable wall of the chamber being integral with its pleated sidewall and formed of elastomeric material, the end of said member opposite said moveable wall being rigid and attached to said headband, means for the attachment of said member to the headband permitting limited pivotal movement of the member with respect to the headband, said member being adapted to be positioned at the orbital cavity of and in overlying relation to that eye of the patient to be subjected to surgery with said movable wall contiguous with the closed eyelid of said eye, and means for increasing the pressure in said chamber in monitored increments to thereby apply through said movable wall a predetermined amount of pressure on said eye.

Abstract
Disclosed is a cup-shaped bellows member removably attached to an adjustable headband. One end of the member is positioned to bear against the closed eyelid of a patient being prepared for intraocular surgery and upon whose head the headband has been placed. The opposite end of the bellows member is closed by a plate having a tubular portion communicating with the interior of the bellows portion and adapted to be connected to a means for increasing the pressure in monitored increments inside the chamber formed by the bellows and plate.
