15 Claims. (01.'128-1) ananimal in a controlled germ free environment.
In conducting experiments with biological specimens it is desirable that the animals upon which the experiments are conducted be substantially.
germ-free, or that such germs as the specimens may be subjected to be limited to known germs or virus so that the results obtained may be directly and positively-attributed to the known germ or virus. Various devices may be utilized for controlling the environment in which a specimen is kept, one such device being illustrated in my copendingapplication, Serial No. 148,102, filed June 14, 1.937, ofwhich this application is a continuation in part.` However, it is essential that the animal be germ-free when introduced into such apparatus. Itis well known that the offspring of healthyf animals are substantially germ-free at birth, and it,y is therefore desirable to introduce the lanimals in to the device in which the same are to be maintained in the desired controlled environment at birth. It is also desirable that the newly born animals shall be obtained and introduced into the device without or before they are subjected to exterior contact with the mother.
- It is therefore the primary obje'ct of this invention to provide novel-means by which a caesarian operation may be performed upon an animal.
A further 'object is to provide a device of this character comprising asealed chamber divided into compartments for receiving and holding the pregnant animal, and for receiving the newly born animals. o
A-further object is to provide a device of this character comprisingl a compartment of controlled environment, a compartment for introducing the pregnant animal, and an intermediate compartment adapted to be sealed from the last named compartment and sealed from the rst compartment by a severable partition.
Affurther object is to provide a device of this character with a novel flexible severable partition of materialimpervious to air. y
A further object is to provide a device' of this character wherein an operating table is mounted in a separate compartment off-set from the main compartment and separated therefrom by a lap cloth severable to expose a minimum of the animal operated upon as necessary to perform the operation. j f A further object is to provide a device of `this character adapted to be effectively and completely sterilized prior to use.
A further object is to provide a-device of this character by means of whichv an operation may be performed in a germ-free controlled environment without danger of contamination.
Other objects will be apparentfrom the de.-l 5f scripticn and the appended claims.

Referring to the drawing, which illustrates the preferred embodiment of my invention, the numeral i@ designates the body of the device which 20 is preferably formed of metal in cylindrical form with the seam thereof (not shown) sealed to render the seam air-tight. On the ends of the cylindrical body are mounted flange rings I l in sealed, relation thereto. To these flange ringsare cong5 nected suitable adapter rings l2 by means of bolts I3, there preferably being suitable gasketrme'ans i (not shown) interposed between the flange and adapter rings to provide a sealed joint therebetween. To each adapter ring I2 is secured a suit-v 30 `able connecting chamber IL-preferabltr of cylindrical forrn, the samebeing in turn connected to other suitableunits (not shown) to constitute 'a closed system. l
The bodylt is provided with a ring I5 secured 35 in sealed relation thereto vabout an opening therein at the center of the upper side thereof, said ring supportingr a transparent closure plate .(not shown) which is held to place by a ring I6,
,said transparent plate, having suitable gasket rings at its top and bottom sides to effect ya sealed joint with said rings. On each side Aof, the body l are mounted suitable glove claves I'l in sealed relation thereto whereby the operator may reach into thebody without contaminating the same or 45 breaking the sealed relation thereof. A plurality of electric leads I8 extend intoA body Il),` the said body mounting suitable sealing means i9 through which said leads extend to maintain the sealed condition of the device. The construction of the 50 aforementioned parts of the device is substantially as set out in greater detail in my cepending application, Ser. No. 148,102 led June 14, 1937. y
' Ihej body luis mounted upon a suitable standu ard or supporting frame 26 composed of suitably interconnected and braced uprights. Mounted on frame 20 in sealed relation to body I9 and preferably therebelow is a trap or chamber comprising side and. end walls 2| preferably provided with transparent panels 22, and one of said walls having an access door 23. The trap is also provided With a closure at its bottom (not shown).
The body IIJ is provided with an opening 25 at the center of its lower side in inwardly spaced relation to the walls 2| of said trap. A frame 26 is secured to the outer side of body I9 at the margin of opening 25. The upper edge of said frame 26 conforms to the contour of the body I0 and is provided with a marginal outwardly projecting flange 21 secured to the body in sealed relation by securing members 28. The bottom edge of frame 26 is plane, and is provided with an endless groove mounting a gasket 29. Within the body I0 is mounted a second frame 30 at the margin of opening 25. 'I'he bottom face of said frame 30 conforms to the contour of said body, and is secured in sealed relation thereto by screws 3l extending through said frame and body and into frame 26. The upper edge of frame 30 is plane and is provided with countersunk bores receiving said screws 3l and their heads. Flanges 32 project horizontally from the opposite upper ends of said frame 30 and support horizontal plates 33 within body I0. A lap cloth 34 spans frame 30 and the edges thereof are overlaid by retainers 35 secured to frame 3U by bolts 36 and thereby clamping cloth 34 to place. The cloth 34 is preferably of laminated construction illustrated in Fig. 5, the same comprising outer layers 31 of woven cloth or other like flexible material, and an intermediate layer 38 of some steamresisting, severable material impenetrable by air, such as Cellophane Ihe outer layers 31 are preferably provided with registering slits 39 at the center thereof, for purposes to be hereinafter set forth.
From one side of frame 26 projects a `pair of spaced rigid depending arms 4U terminating below the lower edge of said frame. To the lower end of each arm 4D at 4I is pivoted one end of a link 42 whose opposite end is connected at 43 to a bracket 44 projecting from the outer face of a closure plate 45 adapted to t against the bottom of frame 26. Plate 45 is preferably provided with a ridge 46 projecting from its inner face and adapted to seat against gasket 29. Suitable bolts or other securing members 41 extend through plate 45 outwardly of ridge 46 and are threaded in suitable bores in the bottom edge of frame 26. Plate 45 is preferably provided with a handle 48 at the side thereof opposite arms 40. At the center of the upper or inner face of closure plate 45 is rigidly secured a pedestal 49 which rigidly mounts a plate 50 in spaced parallel relation to plate 4'5, said plate 50 constituting an operating table spaced below cloth 34 when said plate 45 is operatively secured to frame 26.
Suitable conduits 5l for the supply and. exhaust of steam are provided, said conduits being here illustrated as each mounted on and communi'cating with a connecting chamber I4 which opens into body I 0. Water conduits 52 communicate with water jacket 53 of connecting chamber I4 to constitute temperature controlling means. Also, suitable means (not shown) are preferably provided to supply-filtered air to the device.
The glove claves I1 each preferably comprise a cylindrical frame 55 secured in sealed relation to body I0 at the margin of an opening in said body. On the outer end of the frame 55 is pivotally connected a closure plate 56 adapted to be removably secured in sealed relation to the end of said frame by suitable locking means 51. The inner Wall of frame 55 is preferably stepped adjacent its outer end to receive a ring 58 whlchl serves to clamp the outer end of an elongated rubber glove 59 in sealing relation to the periphery of frame 55. Thus the operator may insert his hands and arms in gloves 59 and reach into body I0 without destroying the sealed rotation thereof or contaminating the desired controlled environment therein.
In using the device, an unbroken lap cloth 34 is rst secured to span frame 30 and seal the body l0 from the remainder of the device including the trap. Body HJ is then connected with such other units as may be desired with sealed joints and the whole is sealed to constitute a sealed assembly;` or, in the event the device alone is to be used, the same is so sealed, although it is preferably provided with at least one connecting member I4 in communication therewith. Prior to the sealing of the device, all necessary instruments, equipment, and possibly food, are inserted in the device, resting upon the plates 33. I'he device is then thoroughly sterilized, as by admission of steam from conduits 5| into the sealed portion of the device, and by cleansing the parts of the trap, frames 26 and 30, and all other parts within the trapl and below lap cloth 34, by use of an antiseptic solution, so that the device is ready for use. In this connection it will be seen that the steam sterilizes all food, instruments and the like within the device in situ, and also serves to sterilize the'entire surface of gloves 59 which are within the device or `come into contact with objects in the interior thereof.
The pregnant animal is prepared for the operation by preferably completely removing the hair therefrom, and then bathing the same in an antiseptic solution. When the exterior cleanliness of the animal is assured, it is inserted into the trap through door 23, and placed upon plate 59 where it is held as the same is swung on links 42 to closed position against the bottom edge of frame 26. The securing members 41 are then applied to force ridge 46 of the closure plate 45 tight :against gasket 29 and thereby form a sealed joint. In this way, a secondary sealed chamber ably being so spaced from cloth 34 that the body of the animal will touch the cloth when supported in proper position on said plate.
The parts all being prepared and sealedy as aforesaid, the intermediate layer 38 of the lap cloth is then slit in line with slits 39 in the outer layers 31 thereof to provide an opening of sufficient size to permit performance of the operation and yet maintain at a minimum the extent of exposure of the body of the animal through said slit. In order to prevent possibility of contamination of the interiorof cylinder I0 by the animal operated upon as from the blood, saliva', excretions, etc., the necessary incisions are preferably made with an electric cauter which practically eliminates loss of blood by the animal and hence eliminates a source of possible contamination of the interior of cylinder I0. In performing the operation, every precaution is taken to prevent contamination of the device by the mother, as by cleansing all organs exposed through the slit in the lap cloth during the operation with an antiseptic solution. ,Y
After the operation has been completed, the newlyborn animals are preferably submitted to only such treatment Within the operating `unit'as is necessary immediatelyY after birth, and are then passed from the operating unit through connecting chamber I4 to aconnected unit of suitable character (not shown) such as the raisingunit described in my aforesaid copending application, there being a suitable closure member (not shown) adapted to be interposed between the connected units to provide a seal therebetween after the transfer. When this transfer and seal has been effected, the closureplate 4,5 may be opened to permit withdrawal ofthe mother from the unit, the exposure. of the interior of the unit at that time being Without dangery of contamination with respect to the young -which are then contained in an independent 'chamber sealed from atmosphere. f
It will be seen that, by securing theclosure 45 in sealed relation to frame -26 before severing cloth 34, all of the parts having4 been previously sterilized and the mother denuded of hair and thoroughly antiseptically cleaned, danger of contaminating the interior of the operating chamber preparatory to and during the operation is entirely eliminated. Whether the trap remains antiseptic after theolosure 45 is sealedis immateral. However, if desired, the trap may be provided with glove claves similar to those in cylinder I0, so that the trap may be sealed after the mother is inserted therein, and the trap and animal then given a iinal antiseptic treatment while in this sealed condition, and before'the mother is placed upon the operating table. It will also be seen that lap cloth 34 being taut, the slit edges thereof will tend to stay together when they are not intentionally separated, and minimum exposure of the animal operated upon is thereby insured, the extent of this exposure being largely within the controlof the operator.
