Definitions

  • This invention relates to tray for sterilising and storing dental and surgical instruments, particularly hand instruments.
  • the instruments are simply loaded loosely into the autoclave. This has the disadvantage that they can damage each other by being knocked together during loading and unloading, or during the sterilisation process, and the dentist may need to search in the autoclave for a particular instrument needed for the next patient.
  • cassettes have been employed into which the instruments are loaded and the entire cassette placed in the autoclave.
  • One example of such a cassette is described in US Patent No. 5284632.
  • One problem arising from the use of cassettes of the kind described in US Patent No. 5284632 have is that they are of complicated construction and, because of their enclosed nature, it is difficult to identify the instruments which have been loaded in the cassette.
  • a dental or surgical instrument tray which comprises a pair of oppositely disposed upright side walls, a rack extended between the side walls for locating instruments in mutually spaced, generally parallel relationship, a clamping bar hingedly attached to one of the side walls and having means for releasably latching the bar to the opposite side wall, thereby clamping the instruments in place in the rack and a holder for releasably retaining small accessories in a part of the tray away from the instruments, said holder being a snap-fit into the tray.
  • the tray will be of open construction having side walls and end walls, and being bridged by one or more instrument receiving racks which are spaced apart lengthwise of the side walls.
  • the holder or holders for retaining the accessories such as burs and brushes are manufactured from a heat-resistant plastics material and have projections which are a snap-fit into opposed upright faces of the tray. Such faces may comprise an end wall and a portion of the rack or a part attached thereto.
  • the holder for prophy paste (used for polishing or cleaning teeth) or dental filling materials may also be manufactured so as to be a snap-fit into the dental tray and is provided with projections for this purpose engaging in upright flanges or other opposed surfaces of the tray.
  • Preferred materials include heat-resistant plastics materials and stainless steel, examples of heat-resistant plastics being fluorinated polymers, e.g. P.T.F.E.
  • the tray has no effective base or cover so that the instruments can be easily seen when held in the tray and identified as such. This enables the instruments to be cleaned ultrasonically while they are contained in the tray. Further identification can be provided by colour code buttons which are removably received in holes, e.g. in one of the side walls of the tray. Such buttons are conveniently coloured buttons made from a heat-resistant rubber, such as silicone rubber.
  • the clamping bar may be spring-biased into an open position so that as the latch is released, the clamping bar springs up and allows easy access to the instruments.
  • the clamping bar incorporates an elastomeric or rubber clamping strip attached to its underside.
  • such rubbery material is a non-foamed material and has a profile including at least one flange which is designed to press onto the instruments.
  • the tray may include a holder for an indicator strip.
  • Such strips contain a chemical which changes colour after it has been subjected to a heat treatment which would be adequate to sterilise the instruments.
  • the preferred sterilisation treatment is by steam or hot air
  • other sterilising gases and liquids may be employed.
  • steam air or nitrogen
  • a temperature of 110 ⁇ 120°C for .about 10 minutes is usually sufficient to achieve effective sterilisation.
  • sterilisation include chemicals (e.g. ethylene oxide), ultraviolet radiation, microwave radiation or radiation from a radio-active source.
  • Figure 1 is a perspective view of a tray in accordance with the invention.
  • Figure 2 is a plan view of the tray shown in Figure 1;
  • Figure 3 is a perspective view of a handle for use in removing a tray from an autoclave;
  • Figure 4 is a section taken on the lines IV-IV in Figure 1 ;
  • Figure 4A is a sectional view of an identification button on an enlarged scale.
  • Figure 5 is a perspective view of a storage container for storing trays of the kind shown in Figure 1.
  • the tray comprises an open framework formed from the pair of side walls 1 and 2 and end walls 3 and 4.
  • Side walls 1 and 2 are bridged by racks 5 and 6, each having a plurality of notches 7 for receiving a variety of dental instruments 8 (see Figure 2).
  • the side and end walls and the racks have a common base flange 10 and the walls and flange 10 may be manufactured by stamping from a suitable corrosion-resistant sheet metal such as stainless steel.
  • the end walls and side walls are formed by folding at right angles to the flange portion 10.
  • side walls 1 and 2 and end walls 3 and 4 together with the flanges 10 are typically of an integral construction.
  • Side wall 1 may be formed with a series of apertures 1 1 and 12 to reduce the weight of the tray and to permit adequate access of steam, hot air or other sterilising fluid to the instruments.
  • This open design enables the instruments to be hand cleaned and allows ultrasonic cleaning of the instruments while in the trays.
  • the holes 12 or corresponding holes 13 in the other side wall 2 may be used for receiving coloured identification buttons which can be removably inserted into the holes.
  • a section through a typical button is shown in Figure 4, and such buttons are preferably manufactured from silicone rubber.
  • the tray includes a plastics holder 20, which is provided with a series of holes for retaining burs, brushes prophy cups and the like.
  • a plastics holder 20 for burs and the like
  • a second holder 21 for mixing prophy paste and other dental paste and filling materials. Because the holders are retained releasably, e.g. by a snap-fit into the tray, they can be exchanged in a given dental tray.
  • this is typically manufactured as a generally cylindrical or otherwise elongated plastic block, having small projecting portions 22 at each end, which are a snap-fit in corresponding holes in an end wall 3 and in a flange 24 attached to one of the racks 5.
  • the rack includes a slot for a matrix retainer 28
  • a similar projection 22 is formed at each end of the plastic block and this similarly engages in corresponding holes in the end wall 4 and in a flange 24 of the rack 6.
  • the instruments are held in place by a clamping bar 25.
  • This is hingedly attached at 26 to the side wall 1 and has a releasable latch 27 (not shown) at the other end
  • the latch may comprise an inward projection from the clamping bar which engages in a hole in the side wall 2.
  • the clamping bar also incorporates clips 30 for retaining an indicator strip 31.
  • Strip 31 is impregnated with a chemical which changes colour or shade once the instruments have been subjected to an adequate sterilisation cycle.
  • Clamping bar 25 incorporates a rubbery gasket 32 for pressing the instruments firmly into the rack.
  • the profile of the gasket is shown clearly in Figure 4 and is an extrusion of a heat-resistant rubber such as silicone rubber.
  • the extrusion includes at least one flange 33, which deflects when the clamping bar is pressed into contact with the instruments.
  • Figure 3 is a perspective view of a handle 40 for lifting dental trays from the autoclave. At one end, the handle has hook members 41 and 42 which are adapted to engage respectively with the upper lower edges of side wall 2.
  • Figure 4 shows a sectional view of one of the colour identification buttons 13. These have a waisted portion 60 for temporarily holding a button in a hole in the side wall of the tray. Such buttons may also be used as plug in feet locating in holes in the flange 10, thereby protecting the dentist's working surface, and prevent the tray slipping on such a surface. The holes for the feet are located in positions in the flange 10 so as not to impede placement in the storage rack shown in Figure 5 .
  • Figure 5 shows a storage rack in which the trays shown in Figures 1 and 2 may be stored before or after sterilisation.
  • the storage rack is of open construction having two upright side walls 50 and 51, and shelf members 52 formed by cutting and bending portions at right angles to the side walls 50 and 51.
  • the width of the opening between the walls 50 and 51 is designed so that the end walls of the trays 3 and 4 will rest on the shelf members 52 so that the front side wall 2 extends across the front of the racks and the trays can be identified as to their owner or their contents, by the colour coding buttons 13.
