Disclosed is a small animal intraventricular injection compensator for injecting a drug into a desired location through a syringe, the compensator including: a guide part provided with a guide hole into which a needle of a syringe is inserted; a body comprising an upper cavity provided inside thereof and a cradle provided to seat the guide part on an upper side thereof; and a fixation part integrally provided with the body or separately provided, and comprising a lower cavity provided to allow a head accommodation space, which a head of a small animal may enter into or exit from, to be provided inside thereof by corresponding to the upper cavity.

A device for performing a radiological examination on a patient having a part of the body examined includes a housing with an openable containment portion and an examination portion. The containment portion and the examination portion together substantially enclose the patient. The examination portion is substantially transparent to X-rays and is configured to contain the part of the body to be examined.

A supporting device for performing radiological examinations on a patient having a part of the body examined includes perimeter side members, an openable containment portion, and an examination portion. The perimeter side members are configured to contain the patient along a closed perimeter and at least in a horizontal plane and substantially in contact, when in use, on a plurality of sides of the perimeter with the patient. The openable containment portion is formed by most of the perimeter side members. The examination portion is formed by the remainder of the perimeter side members, is substantially transparent to X-rays, and is configured to contain the part of the body to be examined.

A versatile subject bed for use with one or more test subjects that is configured to keep the subjects sedated throughout either a surgical procedure or imaging process. In embodiments, the subject bed can include interchangeable manifolds allowing the platform to hold up to four subjects at the same time. The interchangeable manifolds can include configurations designed to provide for a single subject, two subjects or four subjects. The four-subject manifold can include an elevated platform that holds two subject side by side and allows the subjects to be stacked during imaging or other procedures. The subject bed can also incorporate an integrated anesthesia channel. Various embodiments include a docking mechanism for easy connection of anesthesia to the platform, as well as an adapter for fitting smaller or multiple subjects simultaneously within the subject bed.

An animal restraint device for restraining an animal, such as a rodent, for conducting experiments and collecting data. Restraining devices include a cranial restraint to secure the head and torso of an animal, and a caudal restraint configured to secure the torso of an animal. Restraining devices are made of a flexible material and one or more adjustable fasteners. Animal restraining systems include the animal restraint device and a platform for holding an animal restrained in the restraint device. Methods of using the restraining devices and systems are also provided.

Systems for delivering material through an open beak to a digestive tract of a bird and methods of using the same are described herein. Beak opening apparatus and methods of using the same are also described herein.

An animal head gate includes head gate doors each having a squeeze bar to trap the neck mounted between upper and lower rails. Adjustment of the spacing between the bars uses an eccentric crank operated by lever which cooperates with two manual latches on a rail at maximum and minimum spacing. A neck sweep bar is mounted on one gate and movable from a retracted position to a position forward of the squeeze bar across the head gate so as to engage the neck of the animal in front of the squeeze bar and to turn the neck and head. The head gate is held closed by front and rear abutment members each of which is formed as a roller which rotates to reduce friction under load. Each gate includes an upstanding torsion bar which twists when forces are applied to the squeeze bars from impact with the animal.

A device for performing a radiological examination on a patient having a part of the body examined includes a housing with an openable containment portion and an examination portion. The containment portion and the examination portion together substantially enclose the patient. The examination portion is substantially transparent to X-rays and is configured to contain the part of the body to be examined.

A hydraulic control system for a cattle squeeze chute includes a solenoid/valve block in hydraulic communication with a hydraulic pump and electronically coupled to a user control unit. Upon receiving a user initiated input signal from the user control unit, the solenoid/valve block activates the proper solenoid to control a squeeze panel, head gate or other moving component of the cattle squeeze chute.
