CHAMBER FOR HOUSING ANIMALS DURING ANAESTHETIC PROCEDURES

摘要

The present invention provides a chamber having at least one operator hand access port; the port comprising a port aperture located within the chamber wall; and at least two flexible non-resilient lightweight sealing gas-tight flaps(SFs), disposed the same plane of the port aperture in an overlapping manner, entirely enclosing the port aperture; each of the SFs is defined by a port aperture edge and chamber edges; the chamber edges are anchored to the chamber wall along more than half of the perimeter of the flap, at a distance from the center of the port greater than the radius of the port and beyond its perimeter; the port aperture edge of each flap is stretched across an entire chord of the port aperture; stretched port apertures edges define an interior access zone, disposed the same plane of the port aperture, characterized solely by the port aperture edges.

1. A chamber having at least one operator hand access port; said port comprising a port aperture located within said chamber wall; and at least two flexible non-resilient lightweight sealing gas-tight flaps (SFs), disposed within the same plane of said port aperture in an overlapping manner, entirely enclosing said port aperture; each of said SFs is defined by a port aperture edge and chamber edges; wherein said chamber edges are anchored to said chamber wall along more than half of the perimeter of said flap, at a distance from the center of the port greater than the radius of the port and beyond its perimeter; further wherein said port aperture edge of each flap is stretched across an entire chord of said port aperture; such that said stretched port apertures edges define an interior access zone, disposed within the same plane of said port aperture, characterized solely by said port aperture edges of said SFs.
