Abstract

An apparatus for shielding medical personnel from radioactive materials being administered to a patient in need thereof, including a radioactive syringe shield and a radioactive fluid pump shield. The radioactive syringe shield includes a syringe main body, and syringe shields proximal and distal ends each configured to attach to opposite ends of the syringe shield main body in a threaded male/female connection. Together, the syringe shield main body, and proximal and distal ends are configured to contain therewithin a medical syringe containing radioactive medical fluid. The radioactive fluid pump shield is a shielded box configured to contain the fluid pump and has top and front portions pivotally attached to adjacent portions to allow selective access to the fluid pump.

Claims (29)

1. A syringe radiation shield consisting essentially of:

a first rod having a first end and a second end and a first rod central bore extending between and through said first and second ends, said first rod central bore dimensioned to receive a fluid containing portion of a medical syringe;

a second rod having a third end and a fourth end, and a second rod central bore extending partially but not entirely from said third end toward said fourth end, wherein said third end is configured to attach to said second end of said first rod in a threaded male-female connection, said second rod central bore dimensioned to receive a fluid lock at a forward end of said medical syringe;

a third rod having a fifth end and a sixth end, and a third rod central bore extending partially but not entirely from said fifth end toward said sixth end, wherein said fifth end is configured to attach to said first end of said first rod in a threaded male-female connection, said third rod central bore dimensioned to receive a plunger portion of said medical syringe;

wherein walls of said first, second, and third rods are made of a material and thickness sufficient to shield medical personal from radiation from radioactive materials contained in said medical syringe.

2. A fluid pump enclosure comprising:

a rectangular box comprising front and back panels, two side panels, a top panel and a bottom panel,

said top panel arranged and configured to permit user access to contents of said rectangular box,

said front panel arranged and configured to permit user access to said contents,

said rectangular box dimensioned to receive within a radioactive fluid pump for the delivery of radioactive fluids to a patient;

each of said front panel, said back panel, said two side panels, said top panel and said bottom panel constructed of a material and thickness sufficient to shield medical personnel from radiation from radioactive materials contained within or passing through said fluid pump enclosure.

3. The fluid pump enclosure according to claim 2 , further comprising said radioactive fluid pump.

4. An apparatus for shielding medical personnel from radioactive medical fluids being administered to a patient, comprising

a medical syringe;

a radioactive fluid pump,

a fluid pump enclosure; and

a syringe radiation shield;

said fluid pump enclosure comprising

a rectangular box comprising front and back panels, two side panels, a top panel and a bottom panel,

said top panel arranged and configured to allow user access to a top of said radioactive fluid pump,

said front panel arranged and configured to allow user access to a front of said radioactive fluid pump,

said rectangular box dimensioned to receive said radioactive fluid pump;

each of said front panel, said back panel, said two side panels, said top panel and said bottom panel constructed of a material and thickness sufficient to shield medical personnel from radiation from radioactive materials contained within or passing through said fluid pump enclosure;

said syringe radiation shield comprising,

a first rod having a first end and a second end and a first rod central bore extending between and through said first and second ends, said first rod central bore dimensioned to receive a fluid containing portion of said medical syringe;

a second rod having a third end and a fourth end, and a second rod central bore extending partially but not entirely from said third end toward said fourth end, wherein said third end is configured to attach to said second end of said first rod in a threaded male-female connection, said second rod central bore dimensioned to receive a fluid lock at a forward end of said medical syringe;

a third rod having a fifth end and a sixth end, and a third rod central bore extending partially but not entirely from said fifth end toward said sixth end, wherein said fifth end is configured to attach to said first end of said first rod in a threaded male-female connection, said third rod central bore dimensioned to receive a plunger portion of said medical syringe;

wherein walls of said first, second, and third rods are made of a material and thickness sufficient to shield medical personal from radiation from radioactive materials contained in said medical syringe.

5. The apparatus according to claim 4 , further comprising a radioactive medical fluid contained in said medical syringe.
