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 (200or500) 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.
