Fig. 2 is a fragmentary transverse sectional elevation of the assembly of Fig. 1 in assembled relation, the view showing certain features f the improved needle holder on an enlarged scale.

Referring more particularly to the drawings, reference character A represents improved needle-receiving means for receivingand mounting a plurality of hypodermic needles adapted to be inserted with the holder into sterilizing instrumentalities, not shown. The holder A comprises a disc-like member 4 provided with a plurality of perforations for receiving hypodermic needles 6, which are to 'be sterilized, and which are shown as being mounted in the removable ends 8 of hypodermic syringes. The holder A is provided with as many holes as may be needed to accommodate the desired number of needles to be sterilized, and is provided with an annular apron portion I0 which depends from the disc-like portion 4, and which extends beyond the points of the needles 6, so that when the needles have been sterilized and are awaiting use, they are retained out of engagement with any non-sterile surface which might produce a contamination of the needle points.

For sterilizing, the cover B is placed over the holder unit A with the stud l2 of the latter projecting through hole I4 in the cover, this hole being centrally disposed relative to the cover, the cover being conveniently of the same outside diameter and area as the holder unit A, so as to cover and protect the syringe ends 8 that are mounted in the holder A. The clip I6 engages the stud I2, so that the cover B and the holder unit A may be lifted together as a unitary structure and inserted in a steam sterilizer or other sterilizing instrumentalities, not shown. When the sterilization is completed, the cover and holder unit may be lifted as a unit from the sterilizer by lifting on stud I2 as a handle member, and placed in protecting Petri dishes, or other receiving means, the complementa] parts of which are indicated at 30 and 32, respectively. When inclosed v in the Petri dishes, the apron or flange portion I0 maintains the needles 6 clear of the bottom of the Petri dishes, and the top edge of the cover member B is almost in engagement with the cover 32 of the Petri dishes, so that the sterilized needles can readily be transported to a convenient location of use Without any danger of loss of sterility or displacement from the holder. When it is desired to use a needle, the cover 32 of the Petri dishes is removed, and the spring clip I6 released from engagement with the stud l2 to permit the cover B to be lifted out of engagement with the syringe portions 8 to enable access to be had thereto.

It will be apparent that it is desirable to support the needles in the holder unit A suillciently nrmly to prevent accidental displacement of the needles from their respective mounting holes. To this end, the holes which receive the syringe ends 8 are formed'with tapering seat portions 34 which conform substantially to the conical ends of the syringes, and which form supporting seats therefor which firmly support the needles in place. This feature is found to contribute importantly t? the successful use of the holder of this inven- It will be understood that the embodiment of the invention herein illustrated and described represents the preferred form of the holder of the present invention, but it will be apparent that various'modifications of structural details may be made withoutk departing from the spirit and sc ope of the invention, as will become readily suggested to one skilled in the art; and, therefore, it willbe understood that it is. intended and desired to embrace Within the scope of this invention vsuch modifications and changes as may be necessary to adapt it to varying conditions and uses asrdefined by the scope of the appended claims.

Having thus described my invention, what I claim `as new and wish to secure by Letters Patent is:

1. A holder for hypodermic needles comprising, in combination, a holding unit including a substantially 'planar body portion provided with openings adapted to receive needle-holding portions of hypodermic syringes, annular ange means surrounding each opening and defining a supporting seat for the needle-holding portions ofthey syringes, an upstanding handle member projecting from the said planar body, a cover unit for the holding unit comprising'a body portion having an opening therethrough to receive the handle member of the holding unit, releasable yclip means mounted on the cover unit for retaining the cover unit in position, the handle vthe said needles in sterile condition.

2. A holder assembly for holding hypodermic vneedles vforV enabling sterilizing and maintenance thereof in sterile condition, which comprises, in combination, a holding unit including a substantially planar body portion provided with openings adapted to receive needle-holding portions of hypodermic syringes, annular flange means surrounding each opening and having an inverted substantially conical configuration corresponding to the congurationof the needle-holding portions of the syringes, the said flange means defining supporting seats for the needle-holding portions of the syringes, annular flange means projecting from the planar body portion of the holding unit to a distance greater than the length of the needles and syringe portions mounted in the openings, whereby the needles, when sterilized, are maintained out of contact with any contaminating medium until ready for use, an upstanding handle member projecting from the said planar body portion, a cover unit for the holding unit comprising a planar body portion substantially commensurate in shape and area with the planar body portion of the holding unit, the said cover unit being provided with a substantially centrally disposed opening for receiving the projecting handle member of the holdingunit, releasable clip means mounted on the cover unit adapted to engage the handle member extending through theY said opening, thereby enabling the holding unit and the cover unit to be manipulated together as an integral assembly, and a housing for the clip means secured to the cover unit, whereby the clip means are permanently attached to the coverunit.
