Abstract

An articulated injector mechanism, inserted into an adjustable passage adjoined to the animal to be vaccinated, is driven by a mechanical or electrical actuator to inject a dose to the animal using hypodermics. The actuator is operated in response to the animal movement, and combined with the injector mechanism to form a reversible portable structure.

Description

Automatic portable vaccinator per step for use vet.

The "Automatic portable vaccinator per step for veterinary use ", is an automatism that injects hypodermic route (intramuscular, or subcutaneous, or intravenous) or intradermally a Injectable dose to each animal that passes through it, without the need for human presence It could be considered an automatic vaccinator by way of cheating

Prior art

The technical sector is that of devices automatic to inject parenteral substances to animals.

There are numerous injectors as guns and multiple syringes to inoculate under the epidermis dose Pharmacological to numerous animals consecutively. A Examples of such devices are those described in the documents EN 2 082974 T3 or WO 01/03605 A1.

All these mechanisms require manipulation of the apparatus and / or animal at the time of injection.

WO 90/06675 describes a gantry for wild animals that are built on a path, and that it is used to fumigate or spray a preparation on the animal Topical pharmacist.

Explanation of the invention.

Diseases and parasitosis cause numerous damage to wild and domestic animals, resulting in damage Economic and / or environmental. Most medications that prevent diseases such as vaccines, antibiotics, etc. They are injectable intramuscularly, or subcutaneously, or intradermal These injectable preparations have a percentage high efficacy in disease prevention. Without However, health control of wild populations is very hard. The difficulty is because for the administration it is these drugs have to capture animals, which in addition to complicated, it involves intense stress for them because of their handling.

In addition, vaccination of wild animals it implies its periodic capture, because the injectables are not They transmit from one animal to another. This capture is expensive, create stress to animals, makes them leave their burrows and territories, may suffer damage, etc.

The invention comprises a novel system of vaccination. It is ultimately about contributing to the increase and sanitary control of wild animal populations or asilvestrados, whose manipulation to administer drugs via hypodermic or intradermal is very expensive with the state of the Current technique

The "Automatic portable vaccinator per step for veterinary use "includes an animal passageway or tunnel, which has an easily removable mechanism automatic injection of injectable preparations via hypodermic or intradermal This injection mechanism is operated by a activating device for animal passage, which is incorporated. The injector mechanism and / or the activating device are portable, and They are easily coupled reversibly over the passage. When the invention works it is able to inject a dose pharmacological inside the animal body when it is going.

The "trap vaccinator" could be coupled in the burrow entrances and places of habitual passage of the animal species (feeding zones, fencing entrances, etc.), to vaccinate animals automatically and systematically when they leave or enter. Animals come to get vaccinated for your own step, without the need to capture them and without having to being close to no human being (reduces stress).

The "trap vaccinator" includes the following parts:

A. Tunnel or passage . It has size and shape adjusted to the characteristics of the animal, so that the animal always passes very close to at least one of the walls of the passage. Thus its anatomy is located while it is happening, simply knowing anatomical parameters of the species, such as body length intervals.

The passage will preferably have a hole or slot where the injector will enter, another hole for the trigger device and one or more devices to mount the components reversibly and easily, such as crimps mechanical, or screws with coupling brackets. For facilitate the process, the passage may have a narrowing in which the skin of the animal comes into contact with the wall of the passage.

B. Animal presence activating device . This electrical and / or mechanical activator device is preferably detachably coupled to the passage and connected to the injector mechanism, such that when the animal is passing it activates the activator (for example by rubbing it) and it sends a signal to the injector mechanism. This device is able to discriminate the sense of passage of the animal. The activator can be done in many ways:

           \floppy disk
        

A pneumatic valve mechanically operated by an elastic strap on lever.

           \floppy disk
        

A rod switch, such as a limit switch modified.

           \floppy disk
        

Photocells of infrared

           \floppy disk
        

Detectors movement.

           \floppy disk
        

Detectors weight.

           \floppy disk
        

Springs mechanics

C. Injector mechanism . It's automatic. It is detachably coupled to the passage, and functionally connected to the activating device. This mechanism has mobility and preferably hinges, ball joints or other suitable devices to achieve ideal positions during inoculation. It can include two parts: a dynamic pushing device, and a multiple automatic injectors for injections via hypodermic or intradermal.

The dynamic pushing device can be:

to).

A "pneumatic cylinder" powered by a gas accumulator compressed. The pneumatic cylinder can be controlled by a pneumatic solenoid valve, a timer circuit connected to the trigger device, and a battery for supply electric.

b).

Other possibility can be a mechanism "crank-crank" (piston that goes up and down together to a crankshaft) driven by an engine, in turn controlled by a electronic regulator

C).

They can also be several docks pre-tensioned that are released by one or several springs Electrical and / or mechanical.

The multiple automatic injector can use syringes with hypodermic needle, or syringes of intradermal arrangement by spraying with gas under pressure, or a combination of both. In the case of using hypodermic needle, it has a removable fixed stop on the outside, so that the needle can only be nailed to the stop.

This injector can also be a car or Single syringe loader with one dose each. The charger allows to use a different consecutive syringe for each animal that happens. It can be by way of stirring (Fig. 5), linear stirring (Fig. 6a and 6b) or syringe magazine.

Another possibility would be a multiple injector commercial as a gun or syringe auto-recharge

The description of mechanisms has not been entered which are well known in the industry as: cylinder pneumatic, pneumatic valve, revolver, loaders, crank-crank mechanism, injection syringes multiple, etc. since they can be made in multiple ways and models as required.

The operation of the invention would be: We place the passage several days before for the animal to get used to passing for him. On the chosen day we attach the remaining media. When he animal then go through the passageway will activate the device activator, which in turn will activate the injector mechanism. This shape, the dynamic device pushes the injector into the slot on the wall of the "passage", which is above a designated place of the anatomy of the animal (buttocks, muscle, skin ...). When he nozzle is pushed, it protrudes through the passage wall pressing on the surface of the animal and then injecting the content. Once the content is injected, the dynamic mechanism and The injector is removed to its original position outside the passage. The whole process occurs quickly (less than three seconds).

Although there are injectors parenteral route multiple and simple, all these mechanisms involve capture of the animal and the manipulation by a person of the apparatus and / or animal during administration of the injection. exist apparatus such as that described in WO 90/06675 which works regardless of man, but its usefulness is very limited to topical drugs, because they have no means and are not able to administer drugs intramuscularly, subcutaneously, or intradermally; such as commercial vaccines. In addition these artifacts are fixed and many must be built to have control health of the whole animal population. Another drawback is that leaving them in nature for a long time can suffer damage and if they are built quickly the animals would not happen immediately for them, by detecting them as foreign objects. All this makes them Little operational in nature.

This invention provides a novel solution. technique when combining a portable device that does not require presence of man for its operation, and means to use injectors that administer hypodermic or intradermal route, such as a intramuscular mobile injector. The portability of the invention allows roaming use, so in addition to minimizing the risk damage, is able to control a large extent sanitary and / or animal population with only one device, with minimal stress and cost. It also provides technical means to combine an apparatus that works without interference from man with an injector for tissues crossing the epidermis. This combination is novel because allows to expand the range of drugs (intramuscular, etc.) that are they can use without the presence of man (not only those for topical use, on the skin).

Some technical improvements are detailed to continuation:

1. Detachable mechanism that allows to separate the passage of the remaining means, which are easily transportable, such as when properly arranged for operation inside a protective case. This offers the possibility of leaving the passage before in the field so that animals get used to going through it, increasing the effectiveness of the injection process. The briefcase (with the mechanism injector and / or the activating device), only the essential time for its use, preserving damage, theft and deterioration In addition, the same case can be attached to any passage, which allows its itinerant use. This is another advantage. well with a single injector mechanism, and activating device (briefcase) a large extension can be covered using each day in a different place.

2. Automation with mobile injector mechanism that includes dynamic devices and articulated joints by hinges, or ball joints or other flexible mechanisms. Thus allows to adopt suitable positions for injection such as the approach of the injector to press on the skin of the animal, angle of incidence of the injector on the skin, mobility of the injector with the animal's movement, withdrawal from the injector to the starting position, etc.

3. Syringe loaders and revolvers (Fig. 5) or needles coupled to an automatism that works without interference from man, which allow changing the needle for each injection. This It is an advantage, because injecting with the same needle can produce multiple infections if an animal is infected.

4. Diving mechanism (Fig. 6a and 6b) by nailing spring (3) and recoil spring (4), which act on the injector These springs act consecutively with a only impulse, thanks to the fact that the force of the diving spring is very higher than recoil. First the diving spring acts overcoming the recoil spring (it sticks in), then the nailing spring (injected). The spring is then removed from nailed, releasing the recoil spring that acts by unlocking the needle and returning the syringe to its initial position. This mechanism allows you to functionally associate an injector by way of Stirring single-use syringes with a dynamic device Simple push - recoil.

5. Hypodermic needle with detachable fixed stop, or other devices suitable for controlling the depth of Needle penetration inside the animal, without causing damage. This stop in combination with a mobile injector is a improvement by minimizing the range of animal population sizes, since regardless of the size of the animal and that the needle always have the same exit route (fixed distance) over the inner wall of the passage, it always sticks to it depth. This prevents the needle from deepening too much, damaging internal organs in larger individuals, and that at slightly smaller individuals the needle does not reach them. The needle butt excels enough to reach the animals of smaller size In larger individuals, the elasticity of all your tissues, and a small mobility in the tunnel (leg flexion, curvature of the spine, lateral displacement against the opposite wall, etc.). This together with stop prevents the needle from sticking more than desired or causing damage; saving the variability of sizes of the animal population.

Example of embodiment Portable automatic vaccinator by step for rabbit of mount

With this device, it is intended to vaccinate the rabbit to protect it from two deadly viral diseases, the Myxomatosis and viral RHD. We have searched for a low cost device, Resistant and operative in nature.

It comprises a passageway (Fig. 2) of tubular shape of preferably ceramic material, which has a hollow screw (one). Other devices can be placed on this thyme. He tube has a hole for the hollow screw (Fig. 2, No. 1), and a slot (2) for penetration from outside into injector and to allow its mobility with the movement of the animal.

The activating device (Fig. 1, No. 3), and the injectable injector mechanism (Fig. 1, No. 2) (Fig. 3) go arranged properly for indoor operation of a portable protective case (Fig. 1, No. 4). This briefcase has a hole and a groove similar to those in the passage. The briefcase it is coupled on the hollow thyme by means of a nut.

The activating device comprises a valve Pneumatic mechanically operated (Fig. 1, No. 3), by means of a elastic strap on lever, which works in only one direction. He strap penetrates the hollow thyme into the passage. The pneumatic valve is powered by an accumulator tank of small compressed gas (Fig. 4).

The injector mechanism (Fig. 3) comprises a pneumatic cylinder (1) functionally connected to the device activator. The cylinder rod is attached at its end to a multiple automatic injectors of injectables via hypodermic (4). This cylinder is fixed by means of a hinge as a hinge (2) in the same direction of passage of the animal, and allows to describe the injector a circular path with a tangent that matches that address. The multiple automatic injector is a syringe of auto-recharge (4) by valves anti-return and with a spring (3) between the heel of the syringe and the piston rod. This syringe is fed by a vaccine vial (6). The injector includes a needle hypodermic with a removable fixed stop (5).

The separation between the activator and the groove of injection is such, (few cm) that when the rabbit's back touches the Trigger strap, the injector needle will stick into the hindquarters of the animal.

The end of the pneumatic valve strap mechanical drive peeks inside the tunnel, such so that when a rabbit brushes it, a blow of gas is sent to pressure towards the pneumatic cylinder of the injector mechanism.

When the pneumatic cylinder acts, first pushes the injector towards the animal's skin, sticking its needle just to the limit. Subsequently, compress the spring of the injector, and pushes the syringe plunger, which injects a dose at the desired depth inside the rabbit.

The injector mechanism when articulated through the hinge, it moves with the movement of the animal (Fig. 3), unlocking the skin needle as the angle of penetration of it with the movement of the animal, due to the circular path that describes the tip of the injector. When he animal has passed, the mechanical actuation valve returns to its normal position, returning the injector to its starting state.
