DETAILED DESCRIPTION

[0057] The present invention will be described in terms of the following features: [0058] 10 upper tray [0059] 20 lower tray [0060] 100 saline reservoir [0061] 105 saline reservoir holes [0062] 110 contrast reservoir [0063] 120 towel recess [0064] 125 lip [0065] 130 sharps recess [0066] 140 accessories recess [0067] 150 medicine reservoir [0068] 160 level indicator [0069] 170 syringe holding means [0070] 180 waste holes [0071] 200 continuous wall [0072] 210 wire cavity [0073] 220 wire path [0074] 230 aperture [0075] 240 waste cavity [0076] 245 waste cavity lid [0077] 250 space for a sponge [0078] 260 manifold syringe holders [0079] 265 brim [0080] 270 catheter clips [0081] 280 sharps sheath [0082] 290 connection means [0083] 300 saline and contrast lid [0084] 310 saline and contrast lid notches [0085] 400 wire cavity lid

[0086] In the following description, like features will be given like numerals.

[0087] FIG. 1 discloses an upper tray 10, the upper tray comprising a saline reservoir 100, contrast reservoir 110, towel recess 120, sharps recess 130, accessories recess 140, medicine reservoir 150, and syringe holding means 170.

[0088] The towel recess 120 is L shaped and has a lip 125 positioned within the towel recess such that it is separated into two portions. The base of the towel recess 120 comprises waste holes 180 that correspond with the position of the waste cavity in the lower tray when the upper and lower trays are clipped together (see FIG. 2).

[0089] The syringe holding means 170 are positioned on the rear side of the upper tray 10.

[0090] The saline 100 and contrast 110 reservoirs have level indicators 160 formed by steps. Only the level indicator 160 in the contrast reservoir 110 is visible in FIG. 1. FIG. 3 shows all of the level indicators 160.

[0091] The upper tray 10 and lower tray 20 are configured to be connected with the upper tray 10 above the lower tray 20. This is done by means of integrally formed connection means 290 (see FIG. 2) that provide an interference fit.

[0092] FIG. 2 discloses a lower tray 20, the lower tray 20 comprising a wire cavity 210, a wire path 220, apertures 230, a waste cavity 240 and a space for a sponge 250. The wire cavity 210 is disposed in the centre of the lower tray and is connected to the outside of the lower tray 20 by the wire path 220 and apertures 230. As such, a wire may be inserted into one of the apertures 230 and fed along the wire path 220 and into the wire cavity 210. Continuing to feed the wire into the lower tray 20 will then cause the wire to coil in the wire cavity 210 where it is safely contained and ready for use or re-use. The space for the sponge is present in the wire path and abuts the apertures 230. The base of the wire path is moulded in the space for the sponge to provide a recess that will hold the sponge in place as a wire passes through. The sponge itself is not shown in FIG. 2 to allow the apertures and wire path to be more easily viewed.

[0093] FIG. 2 also shows two manifold syringe holders 260. Catheter clips 270 and sharps sheaths 280.

[0094] The manifold syringe holders 260 are present on the lateral sides of the lower tray 20. They are configured to hold a manifold syringe at an angle to ensure that any air rises to the non-sharp end of a syringe held in the holder 260. The holders 260 are configured to hold a syringe using an interference or push-fit. The holders rise vertically from brims that extend laterally in the plane of the tray beyond a continuous wall that contains the wire cavity 210, wire path 220, waste cavity 240, space for a sponge 250 and sharps sheaths 280. The apertures 230 being disposed in said continuous wall 200. The continuous wall 200 has connection means 290 formed thereon for the purpose of attaching the upper tray 10 to the lower tray 20. The brims 265 with the manifold syringe holders 260 extend beyond the region that is covered by the upper tray 10 when the two trays are attached. This provides unrestricted access to the manifold syringes.

[0095] Catheter clips 270 are disposed on the continuous wall 200 and brims 265. The catheter clips 270 allow a catheter to wrap around the continuous wall and be secured in place.

[0096] The sharps sheaths 280 are situated such that they will be underneath the syringe holding means 170 of the upper tray 10 when the two trays are attached.

[0097] FIG. 3 shows the upper tray 10 of FIG. 1 in plan view. From this view, the level indicators 160 are visible in both the saline 100 and contrast 110 reservoirs. Also, the two saline reservoir holes 105 present in the bottom of the saline reservoir 100 are visible. These serve to drip saline onto the sponge held in the lower tray.

[0098] FIG. 4 shows the upper tray 10 of FIG. 1 in a side-on view, looking from the rear side, at the syringe holding means 170.

[0099] FIG. 5 shows an alternative side-on view to the upper tray 10, looking this time from one of the lateral sides.

[0100] The syringe holding means 170 are here seen protecting away from the main body of the upper tray. The taper of the waste holes 180 can be seen as the waste holes 180 taper as they extend away from the base of the towel recess 120.

[0101] FIG. 6 shows the lower tray 20 of FIG. 2 in a plan view. In this figure, a waste cavity lid 245 is shown. The lid may be configured to sit over the waste cavity, between the upper and lower trays when the upper and lower trays are attached. The lid comprises two notches configured to be positioned, when the lid is in place, directly below the waste holes in the upper tray to allow for waste to be deposited through the waste holes and into the cavity.

[0102] The lid ensures that the liquid waste is less likely to spill FIG. 7 shows the lower tray in a side-on view looking from the direction of the sharps sheaths 280. From this angle, the protection of the connection means 290 from the continuous wall 200 is clearly seen. These projections may be received by moulded indentations in the base of the upper tray 10 so as to secure the two trays 10 20 together by means of interference fit.

[0103] FIG. 8 shows an alternative side-on view to the upper tray 10, looking this time from one of the lateral sides. From this view, the angle of the manifold syringe holders 260 is clearly shown.

[0104] FIG. 9 shows a saline and contrast lid 300. Comparing the shape of the lid 300 to the shape of the saline and contrast reservoirs in FIGS. 1 and 3, it can be seen that the lid covers both reservoirs simultaneously. The lid comprises two arcuate notches 310 that allow access to the saline and contrast by means of a syringe when the lid is in situ.

[0105] FIG. 10 shows the lid of FIG. 9 in a side-on view. As can be seen, there is an indentation between the portion of the lid that would cover the contrast and the portion of the lid that covers the saline. The boundary between the two reservoirs will occupy this indentation when the lid is in place. This prevents the transfer of liquid between the contrast and saline reservoir in the event, for example, that the tray is knocked.

[0106] FIG. 11 shows a wire cavity Lid 400. The wire cavity lid 400 is configured to be positioned between the upper 10 and lower tray 20 and covers the wire cavity 210. The wire cavity lid serves to form a continuous boundary over the wire cavity 210 such that the only means of wire ingress or egress is via the wire path. The wire cavity lid 400, therefore, ensures the coiling of the wires in the cavity and prevents the wires from escaping when pushed into the cavity.
