Abstract

The invention relates to a vaccine syringe for use in veterinary medicine, which is characterized in that a removable magazine is provided for receiving a plurality of hypodermic needles.

Description

introduction

first time In 2008, vaccination in small and large ruminants was considered in Germany in Germany Duty introduced. According to the authorities, the vaccination procedure looks for a cannula change every animal. In the vaccination of so-called farm animals is a Change of the cannula usually not prescribed and not common in practice. It only gives recommendations for the user, when a change of the cannula should take place. For vets and Veterinarians, who are tasked with the implementation of vaccinations, this will new, binding provision adds considerable extra work time mean, in addition elevated the risk of self-injection and a dirt infection.

The solution for this Problem is the development of a new vaccine injection system, at in contrast to the vaccine syringes on the market after each injection, the injection needle (cannula) is automatically changed becomes.

These Vaccine syringe works similarly like a magazine screwdriver for the building trade. This is after each "shot", so after each injection, semi-automatic a new cannula advanced.

description

The magazine syringe has approximately the length of 30 to 50 cm and the shape of a cordless screwdriver ( 1 ). The vaccine bottle, the syringe sits near the handle on an adapter ( 2 ) to minimize the risk of damage. In the "vaccine gun" runs a thin tube in which the vaccine is fed to a piston cylinder, in which the seed volume can be adjusted. ( 3 ). From the piston cylinder ( 4 ) leads another hose ( 5 ) the injectant to the base of the syringe. To the tube, at the end to the base of the syringe, is a conical metal or plastic piece ( 6 ), which emerges from the base upon actuation of the syringe on the pressure plate. The cone does not emerge in the center, but sideways to the left or right out of the base. On the base, whose diameter is about 10 cm, flush a magazine ( 7 ) with the sterile cannulas ( 8th ). These are activated when the pressure plate ( 9 ) intimately connected to the cone. The cannula magazine that seats the syringe can be rotated counterclockwise, locking the magazine for each new cannula. After the injection has been completed, the user of the syringe can manually guide a new cannula to the cone by turning the magazine at the base of the syringe. After all the needles of the magazine have been used once, locks the removable magazine in an end position. Through a so-called bayonet closure ( 10 ), the entire magazine can be removed and replaced with a new, unused one. The cannulas must be sterile packed and protected before use.

Construction and description of the cannula magazine:

The injection needles (cannulas) are in the removable magazine ( 7 ) are arranged in a circle and are guided by a rotary movement to the point at the syringe cone ( 6 ) into the cannula and then push it through the front of the magazine so that the injection can take place in the animal. The cannulas are guided in the magazine in individual shafts in which a compression spring has the task to push the cannula back into the magazine and thereby "neutralize" so that there is no danger from protruding cannulas. The change magazine can be made for a single use, refilling is also possible. Here, the used needles are replaced and replaced with new cannulas.

Description of the advantages of the magazine syringe and the magazine cannulas:

• Time-saving vaccinations
• Sterile and hygienic vaccination process also in so-called Massenvaccinationsen.
• Safe vaccination for human and animal
• No pathogen transmission
• Compliance with the regulatory regulations
• Less costs for the injections (fees) because of time savings
• High acceptance of the vaccination measures in veterinarians and pet owners
• Few vaccine losses because bottle when changing livestock can be left on the syringe.
