Animal restraining device
First Claim
1. An apparatus for restraining an animal, which comprises:
- a frame;
a sheet of impermeable, pliant material secured within the frame, said frame being about the periphery of said sheet and secured airtightly thereto, said apparatus having an opening for the head of the animal;
sealing means associated with said frame for securing the frame and the peripheral portion of said sheet airtightly to a support surface; and
evacuation means secured to said sheet and attachable to an external vacuum source to withdraw air from the space around an animal on said surface under said sheet thereby creating a vacuum for restraining said animal.

Abstract
A device for restraining an animal to an x-ray table while conducting veterinary radiography. The animal restraining device comprises an impermeable, pliant sheet for covering the body of an animal. The pliant sheet is encased by a tubular frame which is attached by hinges to a rigid, planer surface for placement on an x-ray table or to the x-ray table itself. With the animal positioned on the rigid surface or table, the frame and sheet combination is placed in registry with the table as the head or the animal is brought through a head-receiving orifice in the sheet. The tubular frame is connected to an external vacuum source. With the source activated, air is drawn from the apparatus through apertures in the tubular frame, thereby creating a partial vacuum within the chamber defined by the sheet and the table. The pliant sheet closely conforms to the body of the animal, thus immobilizing it by the application of an evenly distributed, but variable, pressure.

3. An apparatus for restraining an animal which comprises:
-
a sheet of impermeable, pliant material to cover the legs and body of an animal on an examination table, said sheet having an opening for the head of the animal; sealing means associated with said sheet for securing the peripheral portion of said sheet airtightly to an examination table; evacuation means including a tubular body secured to said sheet and attachable to an external vacuum source to withdraw air from the space around an animal on an examination table under said sheet; and a collar of resilient material attached to said sheet to close the opening in said sheet airtightly around the neck of the animal.

- 4. An apparatus for restraining an animal while conducting veterinary radiography, which comprises a rigid, planar, substantially rectangular table for supporting the body of an animal and an impermeable, pliant sheet for covering the body of the animal, said sheet further being bounded and encased by a substantially rectangular frame hingedly connected to said table along one side thereof so that said frame is moveable relative to said table to enable the positioning of the animal on said table and further within a chamber defined by said sheet and said table when said frame is placed in registry therewith, said sheet having a head-receiving orifice for maintaining the head of the animal exteriorly of the chamber, said frame having gasket means for effecting an airtight seal between said frame and said table, said frame further being of tubular construction and having apertures formed at selective intervals thereon for the evacuation of air from the chamber when an external vacuum source is applied through an opening in said tubular frame, whereby a partial vacuum develops in the chamber causing said covering to closely conform to the body of the animal while exerting an essentially constant pressure thereon, thereby restraining the animal.

8. An apparatus for restraining an animal while conducting veterinary radiography for attachment to an x-ray table, which comprises a pliant, resilient sheet for covering the body of the animal, said sheet being bounded and encased by a substantially rectangular frame having hinge means mounted on one side thereof for hingedly attaching one side of said frame to the corresponding side of the x-ray table so that said frame is moveable relative to the x-ray table to enable the positioning of the animal on the table and further within a chamber defined by said sheet and the x-ray table when said frame is placed in registry therewith, said sheet having a head-receiving orifice for maintaining the head of the animal exteriorly of the chamber, said frame having gasket means for effecting an airtight seal between said frame and the table, said frame further being of tubular construction and having apertures formed at selective intervals thereon for the evacuation of air from the chamber when a vacuum source is applied through an orifice in said tubular frame, whereby a partial vacuum develops in the chamber causing said sheet to closely conform to the body of the animal while exerting an essentially constant pressure thereon, thereby restraining the animal.
