Abstract
Abstract A receiver for surgical implements which includes a backing sheet of a foamed elastomer, the back side of which is exposed to provide frictional contact with an underlying surface. A plurality of magnetic bars are disposed on the upper surface of the pad backing sheet to receive and retain surgical implements. An impervious plastic cover sheet, coextensive with the backing sheet, conforms to the magnetic bars and adheres to the upper surface of the backing sheet between the magnetic bars. The receiver is capable of being folded to entrap discarded surgical implements between the folded portions of the receiver. The receiver may also be rolled to entrap discarded surgical instruments, or the implements may first be removed to permit the rolled receiver to be sterilized for reuse.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
96 words
A receiver for magnetizable implements, comprising: a. a supporting pad of uniform thickness including two similar portions movable between a coplanar position and a folded mutually confronting position, the portions, when in their coplanar position, adapted to present an upwardly facing surface on which magnetizable implements may be deposited; b. a set of magnet elements mounted on each of the confronting surfaces, for mutual adhering engagement, when the pad is folded; the magnetic elements being in the form of thin strips and their poles being formed at their exposed surfaces, and their surfaces facing the pad.
Claim 2
Dependent Claim
96 words
A receiver for magnetizable implements, comprising: a. a supporting pad of uniform thickness including two similar portions movable between a coplanar position and a folded mutually confronting position, the portions, when in their coplanar position, adapted to present an upwardly facing surface on which magnetizable implements may be deposited; b. a set of magnet elements mounted on each of the confronting surfaces, for mutual adhering engagement, when the pad is folded; the magnetic elements being in the form of thin strips and their poles being formed at their exposed surfaces, and their surfaces facing the pad.
Claim 3
Dependent Claim
50 words
A receiver as defined in claim 1, wherein: a. each magnet element includes a pair of contiguous magnet portions of opposite polarity, and a magnetizable strip underlying and bridging between both portions to define a magnetic circuit capable of completion by a magnetizable implement placed across the contiguous magnet portions.
Claim 4
Dependent Claim
52 words
A receiver as defined in claim 1, wherein: a. the supporting pad is formed of porous elastomeric material having a frictionally clinging back surface; b. and an impervious sheet covers the front surface of the supporting pad intimately enclosing the magnet units and adheres to the supporting pad between the magnet units.
Claim 5
Dependent Claim
36 words
A receiver as defined in claim 3, wherein: a. the supporting pad is rollable as well as foldable, and the magnet units form spacers, when the supporting pad is rolled for entrance of a sterilizing media.
Claim 6
Dependent Claim
98 words
A receiver for magnetizable implements, comprising: a. a backing sheet of porous foamed elastomeric material having a frictionally clinging back surface; b. a plurality of spaced magnet units disposed on the front surface of the backing sheet and extending above the normal surface of the backing sheet; c. and an impervious covering closely enveloping the magnet units and intimately contacting the front surface of the backing sheet between the magnet units; d. each magnet unit including a magnet element formed of plastic material impregnated with magnet particles and a magnetIzable metal strip coextensive therewith underlying the magnet element.
Claim 7
Dependent Claim
98 words
A receiver for magnetizable implements, comprising: a. a backing sheet of porous foamed elastomeric material having a frictionally clinging back surface; b. a plurality of spaced magnet units disposed on the front surface of the backing sheet and extending above the normal surface of the backing sheet; c. and an impervious covering closely enveloping the magnet units and intimately contacting the front surface of the backing sheet between the magnet units; d. each magnet unit including a magnet element formed of plastic material impregnated with magnet particles and a magnetIzable metal strip coextensive therewith underlying the magnet element.
Claim 8
Dependent Claim
41 words
A receiver as defined in claim 5, wherein: a. each magnetic element includes two portions of opposite polarity both in contact with the metal strip and forming therewith a magnetic circuit when a magnetizable implement is placed across their outer surfaces.
Claim 9
Dependent Claim
46 words
A receiver as defined in claim 5, wherein: a. the receiver is rollable into a cylindrical bundle, the magnet units forming spacers to permit access of a sterilizing media into the porous back side of the backing sheet and the front surface of the impervious covering.
Claim 10
Dependent Claim
25 words
A receiver as defined in claim 5, wherein: a. the receiver is foldable to place opposing poles of pairs of magnet units in confronting relation.
Claim 11
Dependent Claim
75 words
A supporting means for surgical implements, comprising: a. a supporting member having a foamed plastic lamination; b. a set of magnetic elements mounted in spaced relation on the supporting member, the magnetic elements being in the form of thin strips with their poles being at their exposed surfaces and at their surfaces facing the pad; c. and a thin impervious plastic lamination encasing the magnetic elements and bonded to the surface of the supporting member.
Claim 12
Dependent Claim
