Abstract
An inoculation device and method are provided. The device includes a hypodermic syringe with a hollow needle that is positioned to inject a small animal in its abdominal area with an inoculant. A work platform supports the animal during inoculation in a back down, face up orientation. Air flow sensing activation mechanism is positioned adjacent a portion of the animal. When the animal is moved into contact with the activation mechanism, drive connected to the hypodermic syringe moves the needle forward to penetrate the animal after which the inoculant is injected.
Claims21
Apparatus for inoculating an animal, said apparatus comprising:
- a hypodermic syringe;
- a needle mounted on the syringe, said needle being movable on a drive path for injecting the animal;
- a drive connected to the hypodermic syringe and operable to move the needle between a retracted position and an extended position;
- a conduit for directing fluid to flow through said apparatus, said conduit having an opening positioned relative to said needle such that upon positioning the animal in the drive path of the needle, the animal at least partially blocks the opening of the conduit to at least partially restrict the flow of fluid through the conduit, said conduit extending in generally parallel relationship with the drive path of the needle at the opening of the conduit;
- and
- a trigger mechanism operatively connected to the drive for triggering the drive to move the needle from its retracted position to its extended position to inject the animal, the trigger mechanism being responsive to the restricted flow of fluid through the conduit to trigger the drive to move the needle to its extended position.

Apparatus for injecting small animals with a fluid, the animals each has an abdominal area, said apparatus comprising:
- a hypodermic syringe;
- a needle mounted on the syringe, said needle being movable on a drive path for injection of said animal;
- a cradle adjacent said needle and adapted for positioning an animal to be injected in a face up position relative to the needle so that an abdominal area of the animal is exposed for penetration by the needle, wherein the cradle has a longitudinal axis and the needle moves at an angle in the range of about −5° through about +5° relative to the longitudinal axis;
- and
- a drive connected to the hypodermic syringe and operable to selectively move the needle between an extended position and a retracted position.

Apparatus for injecting small animals with a fluid, said apparatus comprising:
- a housing;
- a hypodermic syringe movably mounted on the housing;
- a needle mounted on the syringe;
- a drive connected to the syringe and operable to selectively move the needle between an extended position and a retracted position;
- and
- a positioning device positioned adjacent the needle and adapted for positioning an animal to be injected relative to the needle, said positioning device comprising a cradle extending from the housing and opening generally upwardly the cradle including an upwardly facing support surface with its lower most portion positioned at an angle in the range of about 20° through about 60° relative to horizontal the cradle further having a portion defining an opening for receiving a posterior portion of the animal to facilitate positioning the animal relative to the needle, the cradle further including a crossbar positioned adjacent to an end of the cradle most adjacent the housing and spaced from the support surface for receiving the posterior portion of the animal between the crossbar and the support surface.

Apparatus for injecting small animals with a fluid, said apparatus comprising:
- a housing having an end wall;
- a hypodermic syringe movably mounted in the housing;
- a hollow needle mounted on the syringe and movable therewith, said needle being movable in a plane through a needle opening in the end wall;
- a drive operably connected to the syringe to selectively effect movement of the needle between an extended position and a retracted position in the plane;
- and
- a retention platform mounted on the end wall and projecting out from the end wall, the retention platform having an upward opening cradle with a longitudinal axis defining an animal support surface spaced from the needle opening, the plane of movement of the needle being at an angle relative to the longitudinal axis of the cradle in the range of about −5° through about +5°, said support surface and needle being arranged such that an animal to be inoculated can be positioned face up on the support surface whereby the needle in its extended position penetrates an abdominal area of the animal.

- a drive mounted in said housing and connected to the hypodermic syringe and operable to selectively move the needle between an extended position and a retracted position;
- a guide tube mounted on the housing adjacent the needle and adapted for the needle to move through between the extended and retracted positions of the needle;
- a porous member mounted in the guide tube and surrounding a portion of the needle when the needle is in its extended position;
- a source of sterilizing fluid;
- and
- a conduit in flow communication with the porous member and the source of sterilizing fluid, the conduit being adapted to provide a sterilizing fluid from the source of sterilizing fluid to the porous member for application to the needle.
