DETAILED DESCRIPTION OF PREFERRED AND OTHER EMBODIMENTS

[0064] Referring to FIGS. 1 to 14 there is shown a sharps passing tray 10 according to a first implementation of the invention.

[0065] The tray 10 is preferably formed of thin walled plastics material and may be formed by vacuum or injection moulding, for example.

[0066] The tray 10 is generally symmetric about both its major longitudinal axis 12 and minor transverse axis 14.

[0067] In plan view the tray has a generally oval like shape and is formed of a single wall 16 but may be rectangular if desired. The lower edge 18 of the wall 16 lies in a plane and forms the base upon which the tray is supported. The wall 16 extends upwards and slightly inwards from lower edge 18 to upper peripheral edge 20 and then extends inwards and generally downwards to the longitudinal centreline 12.

[0068] The tray has two sets of longitudinally extending instrument receiving recesses. These are arranged end on end with the two sets extending in opposite directions from the transverse centreline. Each set comprises a first instrument receiving recess 22 located toward the end of the tray and a second instrument receiving recess 24 located nearer to the transverse centreline. The first and second instrument receiving recesses are separated by a transverse extending finger recess 26 whilst the two second instrument receiving recesses are separated by a central transverse extending finger recess 28.

[0069] The first and second instrument receiving recesses are generally U shaped with ramps 30 and 32 respectively extending transversely from their upper regions toward the peripheral edge 20.

[0070] The upper surface of each of ramps 30 and 32 extends inwards and downwards from peripheral edge 20 generally in a plane (i.e. they have a flat upper surface) but the upper surfaces may curve downwards, either with increasing or decreasing steepness (i.e. they may be flat, concave or convex).

[0071] FIG. 7 shows a cross-sectional view through the first instrument receiving recess 22 and ramp 30. The ramps 30 extend inwards and downwards and transition into recess 22 at curved portions 36 to steeper wall portions 38. Wall portions 38 are joined to less steep wall portions 40 which in turn join central wall portion 42 that defines, in cross section, a semicircular instrument receiving further recess 44. The wall portions 40 are angled upwards from central wall portion 42 toward wall portion 38 but each extends in a plane that, in the longitudinal direction, remains a generally constant distance from the plane of base edge 18.

[0072] FIG. 9 shows a cross-sectional view through the second instrument receiving recess 24 and ramp 32. In this embodiment the ramp 32 extends at generally the same angle as ramp 30. However, because the tray is wider at that longitudinal location the ramp 32 is lower as it transitions into recess 24 at 46 toward steeper wall portions 48. The transition 46 and wall portions 48 may be a continuously curved wall portion or a curved portion and a planar portion. Wall portions 48 join with less steep wall portions 50. Wall portions 50 joins with central wall portion 52 that defines, in cross section, a semicircular instrument receiving further recess 54.

[0073] As best seen in FIG. 9, wall portions 40 and 50 extend generally in a common plane, as do wall portions 42 and 52. The horizontal transverse extent of wall portions 50 is parallel to the longitudinal axis and generally the same as the horizontal transverse extent of wall portions 40 at the end nearer the ramp 60.

[0074] Between the ramps 30 and 32 the wall portions 34 extend steeply to base wall portion 56 and define the transverse extending finger recesses 26. Base wall portion 56 includes slightly thicker central portion 62. This is a flow leader for moulding purposes and may be omitted.

[0075] As best seen in FIG. 8 the upper surface 64 of wall portion 56 is below the lowermost points of wall portions 40, 42, 50 and 52 and so enables a user more easily to grasp an object located in the recess or central recess. The lower surface 66 of base wall 56 is generally planar but slightly raised compared to peripheral edge 18.

[0076] Similarly, between the ramps 32 the wall portions 58 extend steeply to base wall portion 60 and define the central transverse extending finger recesses 28.

[0077] Base wall portion 60 includes slightly thicker central portion 68. Again this is a flow leader for moulding purposes and may be omitted.

[0078] As best seen in FIG. 10 the upper surface 70 of wall portion 60, including central surface 68, is at or below the lowermost points of wall portions 50 and 52. The lower surface 72 of base wall 56 lies generally in a plane but is slightly raised compared to peripheral edge 18.

[0079] The length of the tray is sized to enable a scalpel comprising a handle and blade to be stored temporarily in the tray. The user may place a scalpel on the ramps 30, 32 with the blade edge facing the centreline. The scalpel then slides down the ramps 30, 32 and falls into one or more of the instrument receiving recess 22 and 24 with the blade generally angled downwards and facing away from the user. The angled nature of the wall portions 40, 50 and the central further recesses 44 and 54 assist in this, with the lower edge of the scalpel handle being more likely to be received in one or more of the central further recesses and with the upper edge of the scalpel handle resting against one of the side walls portions 38, 48 or 46.

[0080] A needle may be temporarily placed in the tray and located partially in one or more of the further recesses 44 and 54. The further recesses 44 and 54 are sized so that the point of a needle located in these further recesses cannot be contacted by a user merely by placing a finger on the side wall portions 40 or 50. Preferably the longitudinal length of the further recesses 44 and 54 is such that at least part (preferably the blunt rear end) of a standard medical needle will extend out of the further recesses and into the finger recesses so as to enable a user to grasp that part when needed.

[0081] As best seen in FIG. 2, each further recess 44 extends beyond the instrument receiving recess 22 and communicates with an additional slot or recess 80 that extends sideways from adjacent the closed end of further recess 44. The additional recess 80 is delineated from ramp 22 by wall portion 82 which has curved surface 84. The peripheral wall 16 has a curved access opening 86 at the ends of the tray, as best seen in FIG. 4. As best seen in FIGS. 11 to 13, the additional recess 80 is sized and shaped to accommodate the finger flanges 88 of a syringe 90, with the barrel 92 supported in the tray by finger flanges 88 and/or parts of the barrel 92 resting on curved surface 84 and/or other portion(s) of the tray and generally located in recesses between ramps 30 and 32. The curved access opening 86 allows the plunger 94 to extend out of the tray.

[0082] The angled ramps 30 and 32 serve to aid in centring the syringe in the tray when initially placed in the tray.

[0083] Whilst the further recess 44 extends beyond the instrument receiving recess 22 and communicates with additional recess 80, it will be appreciated that this is not critical and wall portion 82 may form a barrier between the further recess 42 and additional recess 80, with wall portion 82 having a single continuous curved surface portion.

[0084] Referring to FIGS. 15 to 20 there is shown a sharps passing tray 110 according to a second implementation of the invention. The tray 110 is similar to the tray of the first implementation.

[0085] The tray 110 is preferably formed of thin walled plastics material and may be formed by vacuum or injection moulding, for example.

[0086] The tray 110 is generally symmetric about both its major longitudinal axis 112 and minor transverse axis 114.

[0087] In plan view the tray has a generally oval like shape and is formed of a single wall 116 but may be rectangular if desired. The lower edge 118 of the wall 116 lies in a plane and forms the base upon which the tray is supported. The wall 116 extends upwards and slightly inwards from lower edge 118 to upper peripheral edge 120 and then extends inwards and generally downwards to the longitudinal centreline 112.

[0088] The tray has a pair of longitudinally extending instrument receiving recesses 122 extending in opposite directions from the transverse centreline 114. The instrument receiving recesses 122 are separated by a transverse extending finger recess 126.

[0089] The instrument receiving recesses are generally U shaped with ramps 130 respectively extending transversely from their upper regions toward the peripheral edge 120.

[0090] The upper surface of ramps 130 extends inwards and downwards from peripheral edge 120 generally in a plane (i.e. they have a flat upper surface) but the upper surfaces may curve downwards, either with increasing or decreasing steepness (i.e. they may be flat, concave or convex).

[0091] FIG. 19 shows a central cross-sectional view showing the receiving recess 122 and ramp 130. The ramps 130 extend inwards and downwards and transitions into recess 122 at curved portions 136 to steeper wall portions 138. Wall portions 138 are joined to less steep wall portions 140 which in turn joined central wall portion 142 that defines, in cross section, a semicircular instrument receiving further recess 144. The wall portions 140 are angled upwards from central wall portion 142 toward wall portion 138 but each extends in a plane that, in the longitudinal direction, remains a generally constant distance from the plane of base edge 118.

[0092] Between the ramps 130 the wall portions 158 extend steeply to base wall portion 160 and define a transverse extending finger recess 128. Base wall portion 160 includes slightly thicker central portion 168. This is a flow leader for moulding purposes and may be omitted.

[0093] As best seen in FIG. 19 the upper surface 170 of wall portion 160 is below the lowermost points of wall portions 140, 142 and so enables a user more easily to grasp an object located in the recess or central recess. The lower surface 172 of base wall 160 is generally planar but slightly raised compared to peripheral edge 118.

[0094] The length of the tray is sized to enable a scalpel comprising a handle and blade to be stored temporarily in the tray. The user may place a scalpel on the ramps 130 with the blade edge facing the centreline. The scalpel then slides down the ramps 130 and falls into one or both of the instrument receiving recess 122 with the blade generally angled downwards and facing away from the user. The angled nature of the wall portions 140 and the central further recesses 144 assist in this, with the lower edge of the scalpel handle being more likely to be received in one or both of the central further recesses 144 and with the upper edge of the scalpel handle resting against one of the side walls portions 138.

[0095] A needle may be temporarily placed in the tray and located partially in one or more of the further recesses 144. The further recesses 144 are sized so that the point of a needle located in these further recesses cannot be contacted by a user merely by placing a finger on the side wall portions 140. Preferably the longitudinal length of the further recesses 144 is such that at least part (preferably the blunt rear end) of a standard medical needle will extend out of the further recesses and into the finger recesses so as to enable a user to grasp that part when needed.

[0096] As best seen in FIG. 15, the further recess 144 and instrument receiving recess 122 communicate with an additional slot or recess 180 that extends sideways from adjacent the end of the recesses 122 and 144. The additional recess 180 is delineated from ramp 122 by wall portion 182 which has curved surface 184. The peripheral wall 116 has a curved access opening 186 at the ends of the tray, as best seen in FIG. 19. As best seen in FIG. 20, the additional recess 180 is sized and shaped to accommodate the finger flanges 188 of a syringe 190, with the barrel 192 supported in the tray by finger flanges 188 and/or parts of the barrel 192 resting on curved surface 184 and/or other portion(s) of the tray and generally located in recesses between ramps 130. The curved access opening 186 allows the plunger 194 to extend out of the tray.

[0097] The angled ramps 130 serve to aid in centring the syringe in the tray when initially placed in the tray.

[0098] Whilst the further recess 144 extends beyond the instrument receiving recess 122 and communicates with additional recess 180, it will be appreciated that this is not critical and wall portion 182 may form a barrier between the further recess 142 and additional recess 180, with wall portion 182 having a single continuous curved surface portion.

[0099] Unless the context clearly requires otherwise, throughout the description and any claims the words comprise, comprising, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of including, but not limited to.

[0100] The features of the invention described or mentioned in this document may be combined in any combination of features where features are not mutually exclusive.

[0101] It will be apparent to those skilled in the art that many obvious modifications and variations may be made to the embodiments described herein without departing from the spirit or scope of the invention.
