  • Patent number: 11653621
    Abstract: A laboratory animal cage including a basin and a removable hood positioned which define an inner space that is closed and not accessible from the outside. The basin includes a flat bottom wall and sidewalls joined thereto, which define a first support edge. The hood is tray-shaped to define a second engagement edge and includes a main cover wall. Positioning the hood over the basin prevents the inner space from being accessed via the opposing first support edge and second engagement edge. With the bottom of the basin positioned on a support plane, the maximum distance between the first support edge and the support plane is 110 mm or less. Additionally, at least 50% of the inner surface of the bottom wall has a minimum height measurement to the inner surface of the hood of at least 127 mm, which is available for an animal.

    Abstract: Implementations of a rack for animal cages are provided. A rack may be comprised of multiple levels stacked together in a vertical orientation. In some implementations, each level of the rack acts as a frame configured to support thereon one or more tubs (i.e., cages). In some implementations, each level of the rack may be comprised of top panels, glides, joint connectors, vertically oriented legs, and cross beams. In some implementations, two glides may be positioned on a level of the rack to support a top panel and tub therebetween. In this way, the glides hold the top panel in position over the tub and thereby prevent an animal from escaping the interior compartment(s) of the tub. In some implementations, a level may be further comprised of a bracket having a lip thereon. In some implementations, the bracket may be used to reinforce the unsupported edges of the top panel.

  • Patent number: 7467602
    Abstract: A laboratory animal breeding device comprises breeding cages, each including a cage body with a part of the cage body being opened and a removable cover for hermetically sealing the opening in the cage body. An air supply device for ventilation inside the breeding cage is attached to the cover of the breeding cage. The breeding cage includes an air exhaust device that is formed of a fan filter unit comprising a fan device and a first filter. The air exhaust device includes an air exhaust opening formed in the breeding cage and a second filter for cleaning air in the breeding cage passing through the air exhaust opening. Outside air is taken into the breeding cage while being cleaned by the fan filter unit, and contaminated air in the breeding cage is exhausted from the air exhaust opening through the second filter to outside of the breeding cage.

  • Patent number: 7131398
    Abstract: An environmental monitoring and controlling system for a ventilated cage and rack system that monitors and measures air flow in the rack at either the rack or cage level. At the rack level, two pressure sensors are provided in a supply air system to accurately monitor the air flow rate into the rack. In addition, two pressure sensors may be provided in an exhaust air system to accurately monitor the air flow rate out of the rack. At the cage level, a cage may be equipped with a highly accurate pressure sensor, including a Venturi tube and thermistor, the monitor the air flow rate in a cage located at any cage position in the rack.

  • Patent number: 6776158
    Abstract: A method and apparatus for anesthetizing one or more laboratory animals is provided. An anesthetic component is introduced into a pressurized gas stream for delivery to laboratory animals. In one embodiment of the invention, a solo apparatus is used to administer anesthetic component to a single animal. The apparatus may also contain a host cage providing a group apparatus connected to the pressurized gas stream that permits administration of anesthesia to one or a group of animals simultaneously. One or more solo and/or group apparatuses may be used to administer anesthetic components to different animals at various dosages. The apparatus may also include a thermoregulatory system that transfers heat to animals as they receive anesthesia to control the animals' body temperature. In addition, the apparatus may include an exhaust system to remove contaminants from exhaust gases and to withdraw exhaust gases from the apparatus or apparatuses.

  • Patent number: 6729266
    Abstract: An animal isolation and caging system which maximizes cage density within a ventilated rack is provided. The rack includes at least one air exhaust plenum, and at least one canopy disposed within the rack for ventilation of the cages housed in a rack system. The rack is capable of supporting a first cage within the rack below a first canopy, and also positioning a second cage below a second canopy. The filter top of the first cage provided by the invention also provides a filter retainer having a filter top retainer wall designed to be in contact with a first canopy unit forming an enclosed space so configured as to create an enclosed space from which the animal isolation and caging system of the invention creates a zone of negative pressure so as to permit air to be drawn into an air exhaust plenum or duct from the interior of the first cage through the top of the first cage.

  • Patent number: 6718909
    Abstract: The invention provides a method of rearing a bird of germ-free status. The method comprises housing a bird as a parent bird, surgically removing an egg in its shell from the parent bird prior to transfer of the egg to the cloaca in the parent bird, incubating the egg still in its shell and hatching the egg to produce a laying bird. The invention also relates to the production of avian eggs of germ-free status.

  • Patent number: 6612260
    Abstract: The present invention is an animal cage adapted for providing supply air to the cage by either static or forced ventilation, comprising, a cage receptacle and ventilation distribution means integral to said cage receptacle for distributing supply air to an interior space of said cage receptacle. A ventilation air supply system that provides air to the entire cage receptacle and allows the air to leave the cage receptacle in the same manner without the need for a filter cap or bonnet. The ventilation system creates an even flow of air along the side of the cage receptacle thus providing an even air flow across the bottom of the cage, and therefore providing a better environment for the animal. The present invention also provides a an animal cage with biological barrier means integral to said cage receptacle for precipitating microparticles and/or contaminants in the supply air out of suspension due to the low velocity of the supply air during static ventilation.

  • Patent number: 4954043
    Abstract: A balance mechanism of an industrial robot is provided with a first balance mechanism for a first arm which is swingably mounted to a stand of the robot and a second balance mechanism for a second arm which is swingably mounted to a distal end of the first arm. The first balance mechanism includes a flexible coupling device such as, for example, a chain, led through a guide, which couples between a coupling element of a coupling member which is mounted to a center of angular movement of a proximal end of the first arm and a spring having one end fixed to the stand and which is moved in the direction of deformation when the first arm is angularly moved. The second balance mechanism includes a counterbalancer disposed in the opposite side to an operation side of the second arm and a center of angular movement of the second arm constitutes a fulcrum. The balance mechanisms can be applied to the robot without exchanging parts greatly even if the robot is installed in any position.
