A connector is characterized by comprising a T-shaped main body, three connecting components and two connecting tubes, wherein the connecting components are arranged on one surface of the main body and located at three endpoints of the T-shaped main body. Each connecting component comprises a concave groove body and a connecting column which is arranged in a cavity of the concave groove body, wherein a gap exists between the connecting column and the inner wall of the concave groove body. The two connecting tubes are arranged between two connecting components at the bottom of the T-shaped main body side by side. Each connecting tube penetrates through the main body. Connecting holes are formed in the other surface of the main body.

A divider panel assembly for being assembled within an interior of an animal enclosure includes a body defined by a plurality of interconnecting horizontal and vertical wires, the body including a height and width defined by a top horizontal wire, a bottom horizontal wire, a first vertical wire and a second vertical wire. A hook end is formed by at least one of the plurality of horizontal or vertical wires of the body, the hook end configured to engage with the animal enclosure. A clip is rotatably coupled to the first vertical wire or the second vertical wire, where the clip includes a first defined opening for receiving the first or second vertical wire and a second opening configured for receiving a wire of the animal enclosure.

A stand-alone chamber or multi-chamber inhalation system has at least two alternative vaporized test liquid supply systems for passive or self-administered delivery of vaporized test fluid and air to one or more test chambers, which can be passive or restraint chambers, based on operator selection of delivery on and off times in a passive mode or actuation of an actuator in the chamber by a test animal in a self-administered mode. In one case, a multiple inhalation chamber system has two or more separate test fluid delivery systems and provides options for selective passive uniform drug delivery to multiple chambers or selective delivery of two or more different drugs to different groups of chambers from different delivery systems so that two different drugs or different concentrations of delivered drugs can be tested simultaneously.

A wire crate latch apparatus having, in a first embodiment, a pivoting member that is continually drawn to a closed position by gravity and that is deflected into a catch when the door having the pivoting member is swung closed. The latch apparatus further includes upper and lower stops to contain a distal end of the pivoting member and to hold the distal end in the position to hit an oblique portion of the catch when the door is closed. In a second embodiment, a sliding latch apparatus is deflected by a catch and is relatively inaccessible from inside of the wire crate by back plates on the latch and catch.

A generating device of simulating a particulate environment for an experimental animal includes an experimental chamber. An ultrasonic atomization device is installed at the bottom adjacent to the center of the experimental chamber. The upper side of the ultrasonic atomization device is connected to a guide device for guiding particles. The guide device includes an air seal cover, and a micro fan is installed inside the air seal cover to drive the movement of particles generated in the ultrasonic atomization device. Air guide pipes are fixedly connected to a side wall of the air seal cover. The generating device has good sealing performance, and can generate a variety of particle simulation environments to accurately and effectively simulate the biological effect of particles in the animal body. The generating device can improve the particle simulation environment, reduce the deviation of experimental data, and ensure the accuracy of the overall experimental data.

An electronic monitor can monitor experimental animals in a cage. The cage has one or more walls that enclose a living space for the experimental animals. The electronic monitor is coupled to the cage. The electronic monitor may include a housing adapted to be mechanically coupled to the cage in a predefined position relative to the cage. A substantially sterile barrier is provided between the living space and the external environment in this coupled state. The walls of the cage may include a signal-interface section. An electromagnetic detector may be coupled to the housing to have a line-of-sight through the signal-interface section and into the living space of the cage. The electromagnetic detector is adapted to detect electromagnetic radiation that is transmitted through the signal-interface section. A controller processes a signal received from the electromagnetic detector to determine a status of the experimental animals or the living space.

A cat house capable of being spliced includes: a side wall defining an accommodating space, and including a connecting hole communicating with the accommodating space, plural fixing holes surrounding the accommodating space, and plural inner corners facing the accommodating space, at least one of the inner corners is 120 degrees; a reinforcing plate disposed in the accommodating space and including plural positioning ribs inserted through the fixing holes, and one of the positioning ribs including a reinforcing hole; and a reinforcing pin inserted in the reinforcing hole in such a manner that the body section is located in the reinforcing hole, and the head section and the tail section are abutted against an outer surface of the side wall. Since the side walls of both a pentagonal cat house and a hexagonal cat house have 120-degree inner corners, the cat houses can be spliced to each other.
