DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to isolation cabinets for housing living creatures in an environment having a high degree of micro-biological security.
The invention has arisen to satisfy a specific need for isolation cabinets to house poultry from day old chicks to approximately ten weeks of age but it will be appreciated from the ensuing description that the same or similar cabinets could be used for housing other living creatures such as mice, rats and other laboratory animals which must be kept in micro-biological isolation.
DISCLOSURE OF THE INVENTION
The invention provides an isolation cabinet to house at least one living creature, comprising;
a cabinet defining an interior chamber to receive the living creature;
an air inlet for admission of air into the chamber; and
an air outlet for outlet of air from the chamber; and
forced airflow means operable to force an airflow through the chamber via the air inlet and air outlet.
Preferably the air inlet is provided with an air purification filter.
Preferably too the air outlet is also fitted with an air purification filter.
Preferably further, the forced airflow means comprises a fan fitted to the air inlet and operable to force air through the chamber and/or a fan fitted to the outlet and operable to draw air through the chamber.
With a single fan fitted to the air inlet, the fan may be operable to maintain during said airflow a positive pressure within the chamber compared with atmospheric pressure. A fan fitted to the outlet may be operable to maintain during said airflow a negative pressure compared with atmospheric pressure.
The construction may be such that a single fan can be interchangeably fitted either to the inlet or to the outlet to permit operation with either a positive pressure within the chamber or with a negative pressure compared with atmospheric pressure. Alternatively separate fans may be fitted to the inlet and the outlet.
The cabinet body may be fitted with at least one observation window and at least one glove port for handling a creature within the chamber.
The cabinet may also comprise a transfer chamber fitted with sealable inner and outer doors opening respectively to the interior chamber and to the exterior of the cabinet and means to purge the interior of the transfer chamber to the air outlet.
The bottom of the interior chamber of the cabinet may be provided with means to collect excreta from the creatrue and to transfer that excreta to a sump in the bottom of the chamber. The bottom of the chamber may be provided with a mesh floor and the means to collect and transfer the excreta may comprise means to hold film material such that it extends across the bottom of the interior chamber beneath the mesh floor to catch excreta and to enable the film to be drawn into the sump. A pass out port may be provided to enable the film and excreta to be withdrawn from the sump without disrupting the isolation of the interior chamber.
BRIEF DESCRIPTION OF THE DRAWINGS
In order that the invention may be more fully explained, one particular embodiment will be described in some detail with reference to the accompanying drawings in which:
FIG. 1 is a side elevation of a pair of isolation cabinets constructed in accordance with the invention and mounted on a pivoting support;
FIG. 2 is an end elevation of the isolation cabinets shown in FIG. 1;
FIG. 3 is a cross-section on the line 3--3 in FIG. 1;
FIG. 4 is a cross-section on the line 4--4 in FIG. 3; and
FIG. 5 is a cross-section on the line 5--5 in FIG. 3.
BEST MODE OF CARRYING OUT THE INVENTION
The drawings illustrate an isolation cabinet installation comprising a pair of isolation cabinets denoted generally as 11 which are carried on a swinging support frame 12 pivotally mounted on a main cradle frame 13. Cradle frame 13 comprises a pair of cradle ends 14 interconnected by a cranked lower bar 15. It is provided with wheels 16 so that the complete installation can be readily moved into a required location.
A fixed axle 17 extends between the upper ends of the cradle ends 14 and
