Abstract
The invention is directed to a method and apparatus for non-invasively measuring and monitoring intraorbital pressure waves and intracranial pressure waves in humans. The apparatus includes a pressure applicator applied to the orbital area around a patient's eye and applies an inflatable bladder with an internal pressure sensor to the eyelid of the patient to measure intraorbital pressure waves.
Claims9
An apparatus for non-invasive measurement and monitoring of intraorbital pressure waves of a patient comprising:
- a pressure applicator with a bladder;
- the bladder comprising an elastic, film filled with a non-compressible media, positioned on the exterior of the pressure applicator;
- a pressure sensor inside the bladder connected to a pressure meter;
- a sealing component extending and connected to the pressure applicator configured to hermetically seal the pressure applicator around the patient's eye;
- a pump connected to the bladder to control and adjust the volume of the media to the bladder;
- the pump also being connected to a control unit for controlling the volume and pressure of media to the bladder;
- the pressure sensor being configured to measure changes in pressure in the bladder and to send measurement signals to a pressure meter;
- the pressor meter being connected the control unit and being configured to transmit data and pressure measurement data to the control unit;
- the control unit being configured to record and store the pressure measurement data;
- and
- a display connected to the control unit configured to display the pressure measurement data.
A method for non-invasive measurement and monitoring of intraorbital pressure waves of a patient comprising;
- applying a pressure applicator of claim one comprising a pressure sensor in a bladder filled with a liquid medium to the closed eyelid of a patient;
- sealing the bladder of the pressure applicator to a patient's orbital area;
- pumping water into the bladder to increase the water volume in the bladder measuring the medium pressure in the bladder;
- increasing the water volume in the bladder until all the air is force out from beneath the seal and the pressure applicator is hermetically sealed to the patient's orbital area;
- measuring changes in the medium pressure in the bladder;
- recording and displaying pressure changes in wave form with a control unit connected to the pressure sensor.
