Definitions

  • the present invention relates to ventilated tables, and more specifically, but not exclusively, to ventilated autopsy or dissection tables.
  • the air surrounding an autopsy or dissection table may sometimes be contaminated with potentially infectious viruses and bacteria which represent a health hazard to personnel working close to the table.
  • effective protection must be provided against these viruses and bacteria, especially where, as in the case of hepatitis B and tuberculosis, they may be life threatening.
  • the cadaver of specimen may give off upleasant odours or formaldehyde fumes which must be removed if the pathologist and mortuary technicians are to carry out their work in comfort.
  • Types (a) and (b) are relatively simple in design and have the advantage of being very easy to keep clean - after use the work top can be wiped down and sterilised with the minimum of effort. However, neither type provides any protection against air born infectious diseases, odours or fumes eminating from the cadaver or specimen and the pathologist and mortuary technicians must rely for protection upon the use of sterile procedures, face masks, etc.
  • Type (c) isolates the pathologist and the mortuary technicians from direct physical contact with the cadaver or specimen and provides full protection. However, by its very nature it is a complex and expensive system.
  • Type (d) provides a continuous downflow of air over the cadaver or specimen which draws air born infectious diseases, odours and fumes away from personnel standing close to the table.
  • U.K. Patent No. 1531457 describes just such a ventilated autopsy table in which the table top is provided with a multiplicity of air inlets over its surface and an air extraction system is provided in the base of the table which draws air past the cadaver or specimen on the table top down through these air inlets. As the air passes through the air extraction system it is filtered to remove any contaminates carried thereby.
  • the ventilated autopsy tables of U.K. Patent No. 1531457 suffers from at least two major drawbacks. Firstly, the downflow of air is uniform around the whole cadaver, when in actual fact the most critical area of the table is around the head and torso of the cadavour. Secondly, pieces of body tissue and body fluids collect in, around and beneath the perforated areas of the table top making it difficult and time consuming to clean the autopsy table effectively.
  • a ventilated table comprising a table top having a multiplicity of air inlet openings therein, a plenum chamber, and air extractor means for drawing air down around the table top through said air inlet openings into the plenum chamber, characterised in that the air inlet openings are provided in and around the pheriphery of the table top.
  • the density of air inlet openings in the pheriphery of the table top is greater at one end that it is at the other.
  • the head and torso of a cadaver In use as an autopsy table the head and torso of a cadaver will usually be positioned at the end of the table top having the greatest density of air inlet openings to ensure the maximum downflow of air thereby. This serves to minimse the risk of air born infectious diseases eminating from the body cavities of the cadaver being inhaled and also removes unpleasant body odours and fumes.
  • a non-perforated area is provided at the centre of the table top where a cadaver or specimen can be worked upon.
  • This non-perforated work area is easy to clean and there is much less likelihood of body fluids and tissues from the cadavours or specimens placed on the table top collecting in the air inlet openings.
  • the centre of the table top is advantageously dished or trough shaped so as to lie below the level of the perforated pheriphery.
  • the non-­perforated work area is also downwardly inclined towards the end of the table with the greatest density of air inlet openings, which is provided with one or more drainage slots. This ensures that body fluids do not collect around the edge of the cadaver or specimen, and facilitates washing down of the table top.
  • the table top is supported on a drip tray or under sump, and the drip tray defines a substantially U-shaped cross section from one end of the table to the other.
  • a drain and an air duct are provided in the floor of the drip tray. Liquids and solids are prevented from running into the air duct by a cowl provided over the top of it.
  • flushing means are provided beneath the table top for supplying flushing liquid from each of a plurality of positions around the table top.
  • said flushing means comprises a plurality of spray jets connected to a source of high pressure water, which spray jets are directed towards the internal walls of the table and across the air inlet openings, so thereby ensuring that body fluids and tissues dropping through the air inlet openings are continously washed off the interal walls of the table. Furthermore, as air passes through the curtain of water formed by the spray jets it is scrubbed of impurities and contaminates.
  • the table top may rest on a ledge, groove or channel provided on an inturned rim of the drip tray. However, it may be more convenient to rest the table top on the spray jets.
  • the autopsty table comprises a support pedestal.
  • this also incorporates a lift mechanism for varying the height of the table.
  • the lift mechanism is hydraulically operated and is controlled by a foot operated pedal.
  • the support pedastel, the service pipes and the air duct are all telescopic to accommodate variations in the height of the table.
  • the table can be rotated and tilted relative to the support pedastel to allow inspection of a cadaver or specimen on the table top from any position.
  • the drip tray is provided with an aperture in the side to which a pressurised canistor may be connected.
  • This cannistor contains a biological cleansing agent which can be released into the plenum chamber to disinfect the interior thereof. After use the cleansing agent can be washed away by spraying the interior of the plenum chamber with water through the spray jets.
  • the ventilated table is virtually self cleaning and that it is only necessary to sterilise the table after each use. Certainly, it not usually necessary to scrub down the table, both inside and out as is the case with conventional ventilated tables.
  • an autopsy table comprising a table top 1 removably mounted on an under sump or drip tray 2 supported on a support pedestal 3.
  • the drip tray 2 is essentially trough shaped and defines with the table top 1 a plenum chamber.
  • an air duct 4 and a drain 5 both of which are connected to appropriate connecting pipework enclosed within the support pedestal 3.
  • the air duct 4 is covered by a cowl 6 to prevent liquids and solids which have collected in the drip tray 1 from running into it.
  • the drain 5 is covered by a drain filter (not shown) and an overflow outlet (not shown) in the side of the drip tray 1 warns the user of any blockages.
  • the support pedestal 3 is telescopic and is extended and retracted by means of an hydraulically operated jack 7 to vary the height of the table top 1.
  • the jack 7 is operated by a foot pedal 8.
  • the pipework to the drain pipe 5 and to the air duct 4 is also telescopic, although as an alternative flexible piping may be used instead.
  • the drip tray 1 is supported on a box shaped metal carriage frame 9 which carries a plurality of precision V rollers 10 on opposing sides. These V rollers 10 are slideably engaged with a vertically orientated track member 11 secured to and supported by the outer casing 12 of the support pedestal 3. This arrangement guides the table as it is raised and lowered and mimimises twisting and vibration of the table on the support pedestal 3.
  • An access door 13 is provided in the side of the outer casing 12 for maintenance purposes.
  • the table top 1 defines a dish shaped profile - that is to say the centre of the table top 1 is depressed relative to the peripheral edge thereof - and the depressed central area 14 of the table top 1 is downwardly inclined towards drainage slots 15.
  • a cadaver is rested on this depressed central area 14 to be worked on.
  • any body fluids run down the slope of the depressed central area 14 and through the drainage slots 15 into the drip tray 2 beneath.
  • any fragments of tissue which are left on the depressed central area 14 of the table top 1 will be washed away down the drainage slots 15.
  • the peripheral edge of the table top 1 is perforated to provide air inlet openings 16 through which air can be drawn past the cadaver on the table top 1 down into the plenum chamber and away through the air duct 4.
  • This downflow of air past the cadaver prevents infectious diseases, fumes and odours being inhaled by the pathologist and mortuary technicians.
  • the density of these air inlet openings 16 is greater at the end of the table top 1 where the drainage slots 15 are found, and it is towards this end that the head and torso of the cadaver are positioned. The reason for this is that infectious diseases, fumes and odours tend to emanate from the opened body cavities and not from muscular tissue around the lower limbs.
  • a right angled flange 17 around the perimeter of the table 1 there is provided a right angled flange 17.
  • the table top 1 is supported in the drip tray 2 through this flange 17 which rests on a plurality of round section stub pipes 18 projecting outwardly from the interior wall of the drip tray 2.
  • Each stub pipe 18 is connected to a water supply tube 19 and has a spray nozzle 20 at the end thereof which is directed towards the sides of the drip tray 2 across the width of the perforated periphery of the table top 1.
  • Each stub pipe 18 and spray nozzle 20 forms a water spray jet from which water is sprayed on the interior walls of the drip tray 1.
  • the autopsy table of the present invention is, by virute it is design particularly easy to clean, indeed it has been found in use that it is virtually self cleaning.
  • the drip tray is kept clean by the water sprayed from the spray jets, but should it be necessary to carry out a full manual scrub down this is simplicity itself. With exposed, and since both component parts are of simple design with very few awkward corners and protrusions to get into cleaning can be carried out with the minimum of effort.
