Definitions

• the field of the invention is that of the design and manufacture of devices for assisting veterinary practices. More specifically, the invention relates to a device for inoculating veterinary products with birds, and more particularly with poultry, according to a technique for inoculating the veterinary product or products at the level of the wing of the poultry.
• an inoculation method consists of depositing the veterinary product at the level of the membrane situated in front part of the wing and extending between the radius and the humerus of the so-called wing-membrane wing . It should be noted that at this point, the wing membrane has a relatively small thickness, of the order of 1 mm thick.
• transfixion also called transfixion or "wing-web”
• wing-web This method of inoculation, also called transfixion or "wing-web”
• Avian pox is a worldwide disease caused by a DNA virus belonging to the genus Avipoxvirus of the poxviridae family. Antigenically different species are distinguished: chicken poxvirus (Avipoxvirus galli), turkey (Avipoxvirus meleagridis), pigeon (Avipoxvirus columbae), canary (Avipoxvirus serini).
• Avian pox is a poorly contagious disease, affecting among other things hens and turkeys, which is characterized by the presence of diphtheritic lesions on the digestive and upper respiratory mucosa. Vaccination against this disease is very important in the farms because it has a heavy economic impact. Indeed, the fowl pox is at the origin of a fall of egg laying and affects the growth performances of the birds.
• smallpox viruses and in particular fowl pox, have emerged as induction of immunity against foreign antigens for which they code.
• These vectors are also used to vaccinate poultry against several other diseases and there may be mentioned, for example, Vectormune® FP-LT Ceva Animal Health which contains a live chicken poxvirus used as a vector to express in vivo antigens of avian infectious laryngotracheitis.
• the method of transfixion is widely used in poultry farms and is an integral part of vaccination campaigns, whether to vaccinate poultry against smallpox or against other infectious diseases.
• the operator seizes the poultry and unfolds a wing so as to reveal the wing membrane;
• the operator is dipping a needle into a vaccine reservoir, which has provided a longitudinally extending wound and forming a kind of reserve for a dose of veterinary product;
• the operator stitches and passes through the wing of the poultry at the level of said wing membrane, on one point or two points (transfixion).
• the veterinary product present in the reserve of the needle is deposited on either side of the needle, in the wound made by the needle.
• a method of vaccination, more generally of veterinary product administration, thus carried out has several drawbacks among which:
• the needle used for the inoculation of veterinary products is successively in contact with the poultry and with the veterinary product contained in the tank in which the needle is soaked, at the risk of polluting the reservoir of veterinary product;
• the invention particularly aims to overcome these disadvantages of the prior art.
• the invention aims to provide a device for assisting the inoculation of a veterinary product in the wing membrane of a poultry that allows to deliver a precise and constant dose of veterinary products.
• the invention also aims to provide such a device that allows to administer a veterinary product to a poultry more efficiently and faster than with the solutions of the prior art.
• Another object of the invention is to provide such a device which allows the operator to proceed to the administration of veterinary product in a secure and ergonomic manner.

• vaccination by scarification is a process that involves scarification on the skin of the subject to be vaccinated, that is to say to achieve a slight injury by a superficial incision of the dermal surface.
• the product to be inoculated with the subject is then brought into contact with this superficial injury of the dermis.
• the superficial injury of the dermis may be provided after the product to be inoculated has been deposited on the dermis.
