`AN ISGLATGR
`
`This inventien relates ta an iealatar to be usafi
`
`for the isslatien 0f laberatery animals fer use in medical
`
`and pharmaceutical research and the like“
`
`Iselaters fer laberatery animals are wellwknown
`
`and are used to previde a nanniefective envirenment fer the
`
`animals by iselatien and previsien ef a filtered air susply,
`
`as requirefi for meaningful experimentation“
`
`These isolaters are generally made 0f clear
`
`flexible PVC film material formed t0 erovide a sealed
`
`envelepe¢ This envelaee is suspended frem a metal framewerk
`
`and carries sleeves and gleves prajeeting inte the isolater
`
`whereby precedures may be carried out within flee iselater.
`
`The intarier Of the iselater may be held at
`
`pressures higher as lewer than atmespheric, aceerding to the
`
`nature of the werk in hand.
`
`Animals contained within an iselator are generally
`
`held in ca es meunted on the back wall. Manipulative
`
`sleeves and gleves preject through the frent of the iselator
`
`late a gap between the frent anfi the cages. This gap must
`
`be kept free 0f obstructien to allaw manipulation 0f the
`
`animals and equipment, This leads ta a lack of sterage
`
`space in which to keep sterilized food, bedding and the
`
`like.
`
`10
`
`15
`
`20
`
`25
`
`
`
`2
`
`Furthermore,
`
`the iaeiatihg requirement 0f the
`
`iselater leads t0 difficulty in intreducihg bulky feed and
`
`bedding into the iamlaters withhut breach 0f the ieelater
`
`eentainmeht.
`
`Te date this has been achieved by a leek
`
`f
`
`i
`
`Chamber ceneietihg hf a length ef tube sticking in from the
`
`front well, each enfl ef the tube being remevably cevered.
`
`This ie rather inconvenient, has very limited (if any)
`
`storage capacity, and eeeubiee space in the free veiume ef
`
`the ieelater which ceuld better be utilized fer
`
`10
`
`manipulations.
`
`The breeeht inventien addressee theee prehieme,
`
`in the preeeht iaoieter the fleer of the ieelater
`
`is at least partially replacefl by eterege bihe having lide.
`
`When the lids are closed,
`
`they are generally flush with the
`
`15
`
`fieer. Therefere when the iide are eleeed the interier ef
`
`the isolator has the same fleer Shame available he in
`
`traditibhal isolatere.
`
`The bihe may run along the length Qf
`
`the eage and to a dehth campatibie with the reaeh of the
`
`gloves and ea opening the lies gives aeeeee te a
`
`29
`
`canaiderahie eterage velume,
`
`Traditiehaiiy,
`
`ieelatexe have been made with the
`
`eaveiepe farming a eemhlete “bubble“ including the fleet of
`
`the ieeiater. Thie weuid make the eenetruetieh 0f the
`
`T
`
`fieerwmhuhtefi bins impractieai.
`
`The invention therefere
`
`25
`
`embraces the eanetruatien ef the fleet aha eterage bias as
`
`a ehewbieee basemtray far example ih glaaewreinfercefi
`
`
`
`3
`
`plastic so that a smooth, radiused, easily cleaneble
`
`interiet is preeented“
`
`An envelepe, or cemepy, consisting
`
`0f the ceiling and eifie walls at the isolator is then sealed
`
`gaemtight t0 the edge at the beeewtrey by wrapping the
`
`eenepy areune e lengitndinel peripheral flange meulfied es
`
`part of the besewtrey.
`
`It is then secured by a eentinueus
`
`Umeheped preerietery strip pressed ever canopy and flange.
`
`It is a further abject 0f the present inventien to
`
`provide a meene fer intredueing supplies of feed, bedding
`
`end equipment into the isolator. Thle is achieved by
`
`yrsviding doors in the besemtray to ellew cemmunieetion
`
`between the outside 0f the iseletet and the sterege bine‘
`
`The sterage bins are new previded with deere fer
`
`cemmunieetien with the exterior and lide for cemmunieatlen
`
`with the interior. Thie allews the sterege bins also t0
`
`function ee leek Chambers.
`
`In Greer t0 better leelete the
`
`interior ef the ieelater,
`
`the aware and lids sheuld
`
`ereferebly clese te farm a geewtight seal~
`
`In a further embediment 0f the inventien,
`
`there
`
`20
`
`are baskets previded fer intredueing items into the
`
`isolator.
`
`The storage bins may then be farmed t0 be of a
`
`depth toe great for their bettems te be accessible by the
`
`gloves.
`
`A basket containing the items ie new placed in a
`
`eterage bin.
`
`The tag ef the basket may be reachee by the
`
`glevee and so the basket may be liftee inte the isolater
`
`wherein the contents ef the basket may be removed.

`
`Each eterege bin 9 is previded with a first

`
`sealing manner by a lid 12 which when in paeitien lies
`
`EC
`
`generally flush with the flea: of the ismletor. Thie firet
`
`epening 13 allows cemennicafiian between the eterege bin g

`
`15 ellewe eemmunicatian between the sterege bin 9 and the
`
`
`
`exterior of the isolator.
`
`U!
`
`In a first preferred embmdiment of the invention,
`
`the arrangement is such that glevee 6 and sleeves 4 allew

`the manipulator te reach part ef the eterege bin 9.
`
`in a modificatien,
`
`there is a basket provided in

`the eterege bin 9,
`
`this basket being leadeble via the second
`

`
`glevee 6 and sleevee 4.
`
`in such an arrangement the bottem
`
`0f the bin neefl not be directly accessible t0 the
