Abstract

A simplified glove donning device to inflate and detect pinhole size leaks in elastic gloves using no internal or external energy sources. The device may be mounted to any flat surface. Glove donning cylinders (100) hold elastic gloves securely in place and forms an air tight seal between cylinder (100) and elastic glove. When a hand is inserted into the cylinder (100), sealed with an elastic glove, air in the cylinder is forced out through a one-way check valve (400). When the hand is retracted slightly or fully, the elastic glove is pulled into the cylinder (100) by the vacuum developed below the glove, thus, it expands larger than a hand. The user may then insert a hand friction free and disengages the glove from the cylinder (100) by rolling the cuff up and off the upper edge (130) of the cylinder (100). When the air tight seal is broken, the glove deflates rapidly and conforms to the shape of the hand with no air pockets at the finger tips. If the vacuum indicator (500) indicates a loss of vacuum in the cylinder (100), the glove may have a hole through which bodily fluids can pass.

Claims

1. A device to hold, expand, and detect pinhole voids in, elastic gloves, comprising:

in combination, an essentially cylindrical chamber having an air tight closure means at one end, a hand insertion opening at the opposite end, and a glove holding means formed on an exterior circumference of the chamber, an air check valve interposed between the interior of the chamber and the ambient surroundings, and an analog vacuum indicator in communication with the interior of the chamber wherein said analog vacuum indicator includes a display tube connected to a liquid reservoir wherein a vacuum condition can be displayed in a analog fashion by the analog type vacuum indicator.

2. A device as recited in claim 1 wherein said essentially cylindrical chamber is provided by, a thin walled, elongated, rigid tube.

3. A device as recited in claim 2 wherein the tube is constructed of clear plastic tubing having an outside diameter greater than the unstretched wrist diameter of said elastic glove and having a length greater than the finger and palm portion of said elastic glove.

4. A device as recited in claim 1 wherein said glove holding means is provided by a groove formed on the exterior circumference of the chamber within approximately 4 centimeters of said hand insertion opening, said groove having a depth sufficient to hold the wrist portion of the glove firmly in place while allowing the wrist portion when seated in said groove to be easily rolled out of said groove whereby the glove may be removed from the chamber.

5. A device as recited in claim 1 wherein said air tight closure means is provided by a thin, rigid, planner member bonded to the chamber to form an air tight seal with one end of the chamber and having length and width dimensions greater than the outside dimensions of the chamber.

6. A device as recited in claim 5 wherein said thin, rigid, planner member is constructed of plastic approximately 6 millimeters thick.

7. A device as recited in claim 5 wherein said thin, rigid, planner member extends radially beyond the dimensions of the chamber approximately 3 centimeters whereby said rigid planner member provides a mounting means whereby said mounting means with the chamber attached can be wall mounted.

8. A device as recited in claim 1 wherein a hole is provided through the part of said air tight closure means located in an area encircled by the inside diameter of the chamber, providing a mounting means for said air check valve.

9. A device as recited in claim 1 wherein said air check valve is provided by an elastomeric diaphragm valve interposed between the chamber and the ambient atmosphere, having the valve'"'"'s intake port in first communication with the interior of the chamber and the valve'"'"'s exit port in first communication with the ambient atmosphere, wherein the valve allows air within the chamber to be forced out of the chamber to ambient surroundings while denying air entry into said chamber.

10. A device as recited in claim 9 wherein said elastomeric diaphragm valve is provided by, in combination an essentially circular elastomeric diaphragm type valve center mounted to a ported, rigid valve seat.

11. A device as recited in claim 1 wherein said display tube of said analog vacuum indicator includes a horizontal portion in first communication with the interior of the chamber and a vertical portion in communication with said liquid reservoir wherein small changes in vacuum caused by pinhole voids in the glove are magnified by a large change in liquid movement within said display tube due to the change in pressure.

12. A device as recited in claim 1 wherein, an extension of said display tube passes through an elastomeric seal interposing the interior and exterior of the chamber allowing said extension to be rotated within the seal while maintaining air tightness, enabling said display tube to be inclined from the vertical position thus creating an elongated liquid level display for any given static vacuum wherein an analog change in vacuum is displayed over a longer distance to magnify small changes in vacuum.

13. A device as recited in claim 1 wherein said display tube is constructed of clear plastic.

14. A device to facilitate holding, expanding, and detecting pinhole voids in an elastic glove within a chamber comprising, in combination, a holding means integrated with said chamber to hold said elastic glove over an opening in said chamber, an air control means for evacuating air from said chamber when a displacing means is inserted into said chamber, and a display means to display a change in vacuum within said chamber,

said elastic glove having a mounting portion of such dimensions as to exert a compression force on the entire outside dimension of said holding means of said chamber wherein an air tight seal is maintained during expansion and inflation of said elastic glove,

said chamber including an essentially cylindrical, thin walled, elongated, rigid tube with a closure means on one end and the opposite end of the tube defining the opening to the rigid tube, and said holding means comprising a groove formed on an exterior circumference of the tube, within approximately four centimeters of said opening, to hold said elastic material firmly in place over said opening in such a manner that when a vacuum is created in the tube, said elastic material is pulled into the tube and inflated,

said closure means comprising a rigid planner member having an air tight seal with one end of the tube and extending radially beyond the outside dimensions of the tube an amount sufficient to use said rigid planner member as a mounting means so that said chamber can be wall mounted,

said air control means comprising, a one way air check valve including an essentially circular elastomeric diaphragm valve, center mounted to a ported, rigid valve seat mounted to interpose between said chamber and the ambient atmosphere, having the intake port in communication with the interior of said chamber and the exit port in first communication with the ambient atmosphere, wherein the valve'"'"'s one way action allows air within said chamber to be forced out of said chamber to ambient surroundings while denying air entry into said chamber,

said displacing means comprising, in combination, said elastic glove stretched over said opening to said chamber to form an air tight seal and an object, similar but smaller in outside dimension than the inside dimension of said opening, pushed into the elastic glove covered chamber wherein air in said chamber is displaced and forced through said one way air check valve to ambient surroundings,

said display means comprising, a transparent, elongated display tube having approximately three millimeters inside diameter and a liquid reservior, having one end of the display tube in communication with the interior of said chamber and the opposite end in first communication with said liquid reservoir, wherein a vacuum developed within said chamber sucks liquid from the reservoir into the display tube to display, in analog fashion, both static vacuum and minute changes in said vacuum.

15. A method to inflate, hold and detect leaks in an unpackaged elastic glove comprising the steps of, stretching the wrist portion of the glove over an end of a cylinder having inside dimensions large enough to allow easy entry of a human hand, the opposite end of said cylinder having an air tight closure, and

then releasing the wrist portion of the glove into a groove formed on an exterior circumference of said cylinder approximately four centimeters from the open end of said cylinder, so that the elastic contracts and seats into the groove to improve holding friction and air tightness between the glove and said cylinder, and

then inserting said human hand, held as a loose fist to act as a piston, into the glove covered cylinder thereby stretching the glove and displacing air within said cylinder by forcing the displaced air to exit said cylinder through a passively operated air check valve interposed between the interior of said cylinder and the ambient surroundings, and

whereby the air attempting to enter said cylinder through said passively operated air check valve causes the valve to close, denying air entry to said cylinder, creating a partial vacuum within said cylinder which sucks the glove into said cylinder where it is held inflated by atmospheric pressure on one side of the glove and a partial vacuum on the opposite side, to allow easy entry of the hand, and then retracting said human hand from cylinder;

then observing the change, in the level of liquid sucked into a transparent vacuum display tube having one end of the display tube in first communication with the vacuum created within said cylinder and the opposite end of the display tube in first communication with a liquid reservoir, the vacuum generated in said cylinder pulling liquid from the reservoir into the transparent tube to display, in analog fashion by a changing liquid level, a change in vacuum as would occur if the glove contained a pinhole size void.
