Abstract

A back projection screen that allows the awake patient to move the head and neck freely and yet be able to look at the images that are displayed during surgery, but at the same time allows a surgery crew, in particular an anesthesiologist, to watch the airway passage and the consciousness state of the patient, and to monitor signs including color of the lips, eyes movement, verbal responses, skin sensitivity, and the like, as well as to maneuver for intubation or other procedures without removing the screen during surgery. The back projection screen allows also eye contact and/or face to face interaction, physically or virtually, with the surgeon or other members of the surgery team for effective communication and is suitable for easy cleaning or disinfection from bacteria or viruses as required by operating rooms.

Claims26

Dependent claims

A projection screen comprising:

a laminar body with an arched surface for projection of images that is configured to face the concave side of the arched surface towards a patient, who will see the images therein projected, wherein the arc has a length and angle enough to define a space from the nose of the patient to the center of the arc that is enough to allow a health professional to monitor the patient's signs and symptoms and to maneuver around the patient's mouth and nose in case of emergency;
and
supporting means support the laminar body and place the projection screen on a surface where the patient lays;
wherein the projection screen is made in one piece, without sharp edges, of a material that is sterilizable, disinfectant and/or susceptible of disinfection, and has an opacity enough to allow the patient and the members of the surgery or medical team to see through the projection screen but also to allow the projection of images on the arched surface to be seen by the patient during surgery or medical procedures.
