Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
233 words
A shielding holder for a syringe comprising a holder of high density material, said holder including an open ended arcuate lower portion adapted to receive a syringe therein and having a free lower leading edge, an upper portion integral with said free lower leading edge, said upper portion generally following the arcuate curvature of the arcuate lower portion and overlying the syringe receiving lower portion in upwardly spaced relation thereto, said upper portion extending past and terminating beyond said lower leading edge in an upper leading edge oriented generally parallel to said lower leading edge and in upwardly spaced relation thereto, said leading edges defining an opening therebetween, the orientation of said leading edges relative to each other precluding a direct passage of radiation from a lower portion received syringe through the edge defined opening, and mirror means for viewing a lower portion received syringe through the opening from the exterior of said holder, said mirror means comprising a first mirror positioned within said upper portion generally above said opening for a viewing thereof through said opening, said first mirror facing toward the lower portion, a second mirror and means mounting said second mirror on the exterior of said lower portion below said opening with said second mirror facing said first mirror through said opening for an indirect viewing of a lower portion received syringe by a user looking in said second mirror.
Claim 2
Dependent Claim

A shielding holder for a syringe comprising a holder of high density material, said holder including an open ended arcuate lower portion adapted to receive a syringe therein and having a free lower leading edge, an upper portion integral with said free lower leading edge, said upper portion generally following the arcuate curvature of the arcuate lower portion and overlying the syringe receiving lower portion in upwardly spaced relation thereto, said upper portion extending past and terminating beyond said lower leading edge in an upper leading edge oriented generally parallel to said lower leading edge and in upwardly spaced relation thereto, said leading edges defining an opening therebetween, the orientation of said leading edges relative to each other precluding a direct passage of radiation from a lower portion received syringe through the edge defined opening, and mirror means for viewing a lower portion received syringe through the opening from the exterior of said holder, said mirror means comprising a first mirror positioned within said upper portion generally above said opening for a viewing thereof through said opening, said first mirror facing toward the lower portion, a second mirror and means mounting said second mirror on the exterior of said lower portion below said opening with said second mirror facing said first mirror through said opening for an indirect viewing of a lower portion received syringe by a user looking in said second mirror.
Claim 3
Dependent Claim
77 words
The holder defined in claim 1, wherein said means mounting said second mirror comprises an outwardly projecting wedge of dense material mounted on the exterior of said lower portion immediately below said second mirror, said second mirror being attached to said wedge, said wedge acting as a stop for the fingers of a user facilitating handling of said syringe and holder during injection of the material in the syringe and preventing the fingers from exposure to radiation.
Claim 4
Dependent Claim
22 words
The holder defined in claim 1, wherein said holder is of varying thickness, said lower portion being thicker than said upper portion.
Claim 5
Dependent Claim
36 words
The holder defined in claim 3, wherein said lower portion has an interior longitudinal ridge generally opposed from said leading lower edge for resting against said syringe when said syringe is placed within said lower portion.
