Abstract

An automatic repeater vaccinator apparatus (10) for dispensing a predetermined volume of a fluid into an animal, particularly a fluid which is a vaccine, and reloading after each volume of fluid is dispensed. The apparatus (10) comprises a handheld syringe (100) for dispensing the fluid, a flexible conduit (12) for transferring the fluid from a dispensing means to the syringe (100), and a reservoir (48) for providing the fluid to the dispensing means. The dispensing means is electrically activated by a magnetically closeable switch (preferably a reed switch (142)) in the syringe (100), which enables a predetermined volume of the fluid to be dispensed from the syringe (100) when the dispensing means is activated and reloading fluid from the reservoir (48) to replace the volume of fluid which has been dispensed from the syringe (100) when the dispensing means is deactivated. Preferably, the dispensing means comprises a pump (200 or 500) operated by a linear actuator such as a solenoid (300), which is electrically activated by the magnetically closeable switch in the syringe (100). The apparatus (10) is particularly useful for inoculating poultry, particularly inoculating the poultry by the wing web method using the needle and hub assembly (400) which comprises the filament (402) to prevent leakage between inoculations.

Claims

1-32. -32. (canceled)

33. A needle and hub assembly comprising:

(a) a needle with a distal end and a proximal end and a lumen extending therethrough wherein the distal end is beveled and the proximal end is secured to a hub comprising an elongated body with a chamber therein; and

(b) a filament including a rod with a distal end and a proximal end with a head secured to the proximal end wherein the rod of the filament is slidably positioned in the needle lumen and the head of the filament is positioned in the chamber of the elongated body such that in a first position the head of the filament forms a seal with proximal end of the lumen of the needle to separate the chamber of the hub from the lumen of the needle and the distal end of the rod extends into bevel at the distal end of the lumen of the needle and in a second position the head of the filament is away from the proximal end of the lumen of the needle which opens the lumen of the needle to the chamber of the hub and the distal end of the rod of the filament no longer extends into the bevel at the distal end of the lumen of the needle.

34. The needle and hub assembly of claim 33 wherein the lumen of the needle further includes a hole opposite the bevel at the distal end of the needle.
