DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to the drawing, there is shown and illustrated therein a holder 100 constructed in accordance with the principles of the present invention. The shield or holder 100 may comprise a high density portion I02 fabricated of a high density material selected to provide maximum shielding with minimal thickness and may, for example, comprise a heavy metal such as lead. The holder includes a holder portion 104 with a threaded cover 106 therefor. The holder portion has a window 108 fabricated of a transparent material which may, to provide maximum shielding, be of substantial thickness and may, for example, comprise a leaded glass. The window may be secured, as by means of adhesive, or the like, within a slot 109 provided in the front of holder portion 104.
The holder portion, preferably, is generally cylindrically shaped with a front protruding portion in which slot I08 is disposed. The cylindrical shape and protruding portion provide a C- or U-shaped configuration with the protruding portion 1 10 being located within the legs thereof so as to define a bore I12 adapted to receive a vial or container holding a radioactive material. The top portion of the inner surface of holder portion 104 is provided with thread means.
The top or cover portion is disk shaped having a knurled outer edge 114 to facilitate its manipulation and a threaded stub portion to communicate with and connect to the holder portion 104 enclosing the shielded radioactive material. Cover portion I06 is provided with a concentrically located bore I 16 adapted to receive a plug I 18.
The holder, preferably, is adapted to contain a vial I19 holding radioactive material. The vial is provided with a lon gitudinally extending scale I20 which is visible through the leaded glass or window I08. The scale indicates the volume contained between individual markings, and may indicate volumetric measurement, as in cubic centimeters in accordance with conventional practice. When it is desired to ex tract the contents of the vial into a suitable syringe, the plug I I8 is removed pennitting a needle or the like to be inserted in the vial to draw the radioactive material into the syringe.
While the principles of the present invention may be ad vantageously utilized with a holder for a vial or the like, other embodiments thereof, and, in particular, a shielded syringe holder may be constructed.
With reference again to the drawing, and in particular FIGS. 4-6, there is shown and illustrated therein a syringe 10 disposed within a holder or shield constructed in accordance with the principles of the present invention and designated generally by the reference character 12.
The syringe I0 may be of substantially any desired construc tion and design and may, for example, comprise a cylinder portion 14 and a plunger portion 16 slidably disposed therewithin.
The syringe 10 may be of substantially any desired construction and design and may, for example, comprise telescopingly interengaged cylinder and plunger portions 14 and I6, respec tively.
By way of example only, the cylinder portion 14, may, for example, comprise a generally tubular medial portion 18 of generally uniform diameter and wall thickness; a radially outwardly extending handle portion 20 disposed at one end portion thereof; and a generally conical generally closed end portion 22 at the other end portion thereof. The open end portion adjacent the handle portion 20 may be provided with a generally outwardly extending tapered mouth 24 to enable easy insertion therein of the plunger 16 and the generally closed end portion 22 may be provided with a generally axially forwardly extending boss 26 provided with a bore 28 extend ing therethrough from the apex of the conical portion 22, the outer surface of the boss 26 being generally cylindrical or of slightly tapered configuration so that a conduit-like member, such as a hypodermic needle, catheter, stylet, tubing, or the like, may be readily and easily structurally associated therewith. Yet further, as a further aid in providing secure structural association between the syringe l0 and a mating conduit member, the forward end portion of the syringe 10 may be further provided with a generally annular boss 30 ex tending generally co-axially and radially spaced outwardly of the boss 26 and provided with internal screw threads 32 for engaging such conduit members as may be provided with mating screw threads.
The handle portion 20 may extend substantially entirely radially outwardly of the medial portion 18 or may, as shown, be of generally elongated configuration comprising a pair of generally opposed ear or flange portions 34. The medial p0rtion 18 of the cylinder l4 may, as shown, be provided with a generally longitudinally extending scale 36 for defining and indicating the volume contained between individual markings thereof and the forward end portion 22 or the volume contained therewithin between the piston portion 16 and the forward end portion 22 when a particular pre-determined portion of the piston is aligned with a particular scale graduation. The scale 36 may, for example, and as shown, be constructed and arranged to indicate volumetric measurement, as in cubic centimeters, in accordance with convention practice.
It will be appreciated the syringe 10 is of conventional construction, but for purposes of illustration it is further described as comprising a plunger portion 16 which may have an elongated stern portion 38 comprising, for example, a plurality of webs 40 extending generally radially outwardly from generally axially of the cylinder portion 14 and of such dimension as to fit generally snugly or loosely, if desired, while being yet slida ble within the cylinder portion 14. The plunger portion 16 may further comprise an enlarged cap or actuating portion 42 of, for example, generally circular or disc-shaped configuration disposed at one end portion thereof and an inner cap 44 of generally disc-shaped configuration disposed at the other end portion thereof having a diameter substantially equal to the inside diameter of the cylinder medial portion 18. An elastomeric sealing plug 48 having, for example, a generally conical forward end portion 50 adapted to congruently engage the conical cylinder portion 22 so as to enable substantially complete extrusion or dispensing of material from the syringe l outwardly through the bore 28. The plug 48 may, for example, be fabricated of an elastomeric material and may be pro vided with a generally circumferentially or annularly inwardly extending side groove 52 so as to define a forward and rearward generally circular sealing ring portions 54 and 56, respectively, disposed generally adjacent the conical forward end portion 50 and the forward end portion 44 of the plunger stem 38. The forward end portion of the plunger stem 38 may be provided with means, such as a point 56 having an outwardly bulged portion 58 for retaining the elastomeric plug 48 secured for movement therewith.
The operation of the syringe is believed to be readily apparent and no further explanation or description thereof is deemed necessary.
The shield or holder portion 12 may comprise a high density portion 60 fabricated of a high density material selected to provide a maximum shielding with minimal thickness and may, for example, comprise a heavy metal, such as lead. The shield 12 may further comprise a window 62 fabricated of a transparent material which may, to provide for a maximum shielding, be of substantial thickness and may, for example, comprise a leaded glass. The window 62 may be secured, as by means of adhesive, or the like, within a slot 64 provided in the portion 60 of the holder 12 and adapted to be positioned in general alignment with the graduations of the scale 36 so that the material within the syringe l0 and the scale 36 may be viewed or visually observed, enabling the quantity of material within the syringe to be readily ascertained at any desired time.
The portion 60 of the holder or shield 12 may be of generally U-shaped configuration with the window 62 being secured between the legs thereof so as to define therewith a bore 66 within which the cylinder 18 of the syringe is particularly adapted to be disposed. Means, such as a screw 68 may be provided for clamping the cylinder 18 of the syringe 10 within the holder or shield 22 with the graduations of the scale 36 thereof being disposed in general alignment with the the hiQOdensity portion 60 and communicating with the cylindrical re to define the bore 66 and with the window 62 being disposed within the slot 72. The lower end portion of the density portion 60 may, as shown, be provided with a bevelled portion 74, as shown.
