Description

INJECTION DEVICE WITH PROTECTED INTERCHANGEABLE NEEDLE. MARKING AND INTELLIGENT EQUIPMENT

TECHNICAL SECTOR

The present invention belongs to the industrial livestock sector, and more specifically to the field of devices used for the administration of medication to animals.

The object of the present invention is a new injection device for administering medication and / or vaccines. This device is characterized in that it allows the needle to be exchanged automatically and safely, it marks the animal and exports the information of the process to a database for subsequent analysis.

BACKGROUND OF THE INVENTION

Animal health is a basic element to guarantee the health and welfare of animals and indirectly public health, the economy and the agri-food trade. Given its importance, animal health is subject to regulation and monitoring at the international, European and state level.

There is an increase in the breeding of animals that serve us as food through large farms and intensive production, mainly pigs, cows and sheep, using a production model where the animal is confined and fed to obtain better results in the shortest time possible.

The best way to fight any disease is good prevention. All livestock farms establish a health management plan to prevent diseases, which includes a vaccination plan, a biosecurity program and a control and record of activities related to animal health (treatment book).

In this context, the need arises to improve animal health, avoiding the spread of infectious diseases, mechanizing processes, increasing safety and proposing concrete measures to avoid unnecessary risks by developing prevention systems, disease control and drug traceability registration.

The security and computerization of the chain of processes carried out in each animal is a key point in order to achieve this objective, since the general population would directly benefit from this change. Currently this record is made in writing in the treatment book of each farm, where the administration of medicines or other treatments is reflected, indicating: identification of the veterinarian, date and duration of treatment, medicine, administration, dose / quantity, supplier, pathology , waiting time, animals treated and recipe number.

Farmers carry out mass vaccinations using devices that are slow, heavy and with the risk of an accidental puncture due to the manual needle change, making this procedure laborious and dangerous. There are no injection devices on the market capable of exchanging the needle automatically and safely; And although the recommendations say that a needle must be used for each animal and each type of vaccine, this change is not made due to the technical difficulties previously exposed, favoring the spread of diseases.

As in livestock farms there are several animals in each enclosure, to distinguish at a glance the animals that have been medicated from those that have not, the farmer injects and marks the animal with a striking color, requiring for this process the use of different devices in both hands. Currently marking is done with spray or a solid bar.

The veterinarian performs routine controls of each farm, prescribes the vaccine and / or medication according to the needs and / or vaccination schedule, being reflected by electronic prescription. On the other hand, in the treatment book of each farm (manual annotations) it will be where the procedures carried out by the farmer are recorded, a document that is used to certify that the biosecurity regulations are being complied with in the animal.

The devices that currently exist on the market that use needles for the vaccination / medication administration process all require manual needle exchange (dermal or intramuscular), such as the Dermojet syringe, Hauptner revolver or Humeco® vaccinators. There are needleless injection devices (NFID, for its acronym in English) that work by means of a jet of high pressure air that penetrates the epidermis, dermis and even has some penetration into the subcutaneous tissue. Among these NFID devices are Hipradermic®2.0, for intradermal vaccine administration and the recent introduction on the market, HipraQnect®, with a new injector capable of applying intramuscular vaccines. These devices have been complemented with software (Hipralink®) capable of collecting, analyzing and offering completely new data around the vaccination process, which will allow the user to make decisions, improve efficiency and obtain information automatically in real time. that will undoubtedly make life easier for the main players in animal production.

EXPLANATION OF THE INVENTION

The inventor of the present application has developed a device capable of solving the problems described above. It is an injection device that is characterized by automatically exchanging the needle, incorporating it with a charger and preparing it for firing, which will be activated through a two-step application procedure, thanks to sensors that exist in the end of the device that will be activated when the device contacts the animal and another sensor on the trigger that is activated by the user. After the injection is made, the needle is automatically protected and stored in a tank inside the device, it also sprays a quantity of paint for marking the animal during the same shot.

The main advantages of the device are summarized below:

-The device allows the coupling of intradermal or intramuscular type needles from those sold on the market.

-The needle cannot be manipulated manually during the vaccination and / or administration of medication process, and it protects it immediately after injection, preventing unwanted punctures in the farmer and the animal.

-The device has a double safety system, allowing the injection to be carried out at the desired time.

-The device allows a quick and automatic needle change, facilitating that each animal can be punctured with a different needle.

-The device has a reservoir that stores used needles.

-The device automatically marks the animal after the injection.

- The device allows automatic disinfection / sterilization of the used needle.

-The device can be sterilized when disassembled.

-The device incorporates a computer that records the information of each process, clearly separates the competencies of all the actors in the vaccination process, and provides us with the necessary information to have a complete knowledge of the situation of the animals at all times, providing the system with the quality that technology and information management can provide us today.

-With this device there is more and better information on the part of the owners of the animals, since when the animals can be slaughtered (complying with the regulations on drug waste), who has authorized the use of each drug and at what time it has been produced, if the application by the subcontractors has been made at the agreed time and if it coincides with the number of head of cattle that that farm has. These data will be used for future action plans against disease outbreaks, comparing the effectiveness of different drugs and / or procedures, analyzing the database.

This claimed intelligent endowed, marked and protected interchangeable needle injection device is made up of several pieces that are assembled together. It resembles in its appearance a pistol characterized by a handle, a body, a deposit of paint for marking, a magazine where the needles to be used are stored and a deposit of used needles. At the end of the body there are photocells or limit switches that are sensors that when contacting the animal will activate a safety mechanism of the application in two steps to subsequently activate the trigger and carry out the injection-marking. The injection occurs when the syringe extension that carries the needle comes out of the injecting gun. Subsequently, the syringe extender moves the needle into the gun where the needle fixer unscrews it, immediately the setter takes the needle to the tank where it will be confined. The setter moves to remove a sterile needle from the reservoir and take it back to the fixator, who screws it into the syringe extender, leaving the system ready for a new one. application. The information of the process is exported by the computer located in the backpack to the database.

The device is directly connected to a calibrated syringe housed in the injector backpack, which through tubes and valves will facilitate the arrival of the medication to be administered, it is a computer-controlled electronic mechanized system.

PREFERRED EMBODIMENT OF THE INVENTION

Our injection device is divided into two main parts (fig. 1): the injector gun (4) and the injector backpack (6), joined by a tube (5) that contains all the electrical, mechanical and hydraulic conduits necessary for work as a single system.

Mochila inyectora (6). compuesto por: sistema motorizado de dosificación (9), sistema motorizado de cables (8) y el ordenador central (7).

Injector backpack (6). composed of: motorized dosing system (9), motorized cable system (8) and the central computer (7).

Invector gun (41. consisting of: needle setter (30), needle loader (40), needle clamp (5), needle deposit (60), syringe extension (72) and marking system (104), all within the outer security coating or outer coating (10).

Mechanical operation of aauia change:

Starting from figure 4 we can divide the mechanical operation into three phases:

a) Preparation: the positioning system (30) (fig. 5) removes the needle (1) from the magazine (40) where the fixator (5) will take it. Second, the fixator (5) (fig. 6) brings the needle (1) to the extender (72). Finally, the fastener (5) swings up, to free the space between the needle (1) and the front protection (23a).

b) Application: press the frontal protection (23b) (fig. 7) against the animal. Secondly, we press the trigger (21b) (fig. 8), then the extension (72) moves to the left, taking the needle (1) out of the injection gun (4) and injecting. Third, the motorized dosing system (9) applies the predetermined amount of medicine. Fourth, the marking system (104) paints the animal. Fifth, the extension (72) (fig. 9) moves to the right, leaving the needle inside the injection gun (4). Finally, we release the trigger (21a) and stop pressing the frontal protection (23a) against the animal.

Cambio: partiendo de la figura 9, el fijador (5) (fig. 10) bascula y se aproxima al alargador (72) sujetando la aguja (1), la polea (51) gira en sentido antihorario para desenroscar la aguja (1). En segundo lugar, el fijador (5) (fig. 11) bascula para llevar la agujac)

Change: starting from figure 9, the clamp (5) (fig. 10) swings and approaches the extension (72) holding the needle (1), the pulley (51) turns counterclockwise to unscrew the needle (1) . Second, the clamp (5) (fig. 11) swings to bring the needle

(1) within reach of the setter (30). Third, the setter (30) (fig. 12) raises the needle

(1) and takes it to the tank (60).

The two-step application procedure is the mechanical sequence for safe injection. The ultimate purpose is that the needle only comes out at the time of injection. The steps are:

1- Step one: press the frontal protection (23a) (fig. 6) against the animal to be injected, moving the frontal protection to position (23b) (fig.7).

2- Step two: we press the trigger (21b) (fig. 8), here the injection is carried out. To finish, the user stops pressing against the animal, recovering the frontal protection (23a) (fig. 9) to the initial position and releasing the trigger (21a), being prepared for a new cycle.

Mechanical operation of the application procedure in two steps:

The entire sequence is directed and supervised by the central computer (7) (fig. 2), it has an exact knowledge of where each component of the system is, it regulates the speed and distance in each movement. Time the action times of the different input systems (push buttons, sensors). It has programmed which actions are proper to normal and responsible use, and which actions are proper to manipulation of the system or fortuitous failures, accidental pressure, and so on.

The needle setter (30) carries the needle from the magazine (40) to the fixer (5) and after the fixer (5) to the reservoir (60). We can divide the operation into two phases: remove the needle from the magazine and take the needle from the fixator to the tank.

Sacar aguja de cargador: partiendo de la figura 4, se mueve a la izquierda el colocador (30) (fig. 5) con lo que el sujetador (32) ensalza la aguja (1) y la saca del cargador (40) donde es recogida por el fijador (5).

Remove the needle from the magazine: starting from figure 4, the setter (30) (fig. 5) moves to the left, so that the holder (32) raises the needle (1) and removes it from the magazine (40) where it is picked up by the fixer (5).

2- Bring the water from the fixer to the tank: starting from figure 10, where the fixer (5) swings up with the needle (1). First, the setter (30) (fig. 11) is moved to the left, raising the needle (1) that is on the pulley (51). Second, the setter (30) (fig. 12) is moved to the left, inserting the needle (1) into the reservoir (60) (fig. 12).

of motorization and monitoring in the injector backpack (6) and the moving parts in the injector gun (4). Starting from the state of the injector gun (4) as we can see in figure 15 the skid is in position (72a), the central computer (7) installs the motor (88) (fig.

13) to move clockwise moving the skate to position (72b) (fig. 16), the central computer receives from the pulse generator (89) the exact position and speed of the shoe and adjusts the behavior of the motor at any time ( 88) accordingly. Similarly, the central computer (7) urges the motor (88) to move counterclockwise by moving the skate to position (72a) (fig. 15).

Mechanical operation of the motorized cable system:

Divide the foundation into three parts:

a) Pulse generator (89) (fia. 14): composed of a chassis (811) (fig. 14) that is traversed by the cable (3a). The cable is in contact with the pulley (841) that rotates on the shaft (842), and that moves the perforated disk (82). The photo relays (85) transmit to the central computer (7) whether or not they see the perforation of the disk (82), converting the position of the axis into a digital code, in this way the central computer (7) calculates the movement, speed and cable direction. At each end it has a tensioner (87) with a fixing nut (86), for the mechanical tension of the cable (3a).

b) Motor-mounting of cables: the drum (83) (fig. 13) has a central recess to house the fixing systems of the cables (3a) and (3b), the drum (83) is inserted in the motor shaft ( 88). Divided the operation in two parts:

c) Skate movement: provides a linear movement on the structural guides. As we can see in figure 15 the tubes (2a) and (2b) reach the chassis support (81) where the cables (3a) and (3b) exit. The cable (3b) is fixed on one side of the shoe (72) and the cable (3a) passes through the return pulley (84) and is fixed to the other side of the shoe (72). When the cable motorization rotates clockwise the cable (3a) is wound on the drum (83) pulling the skid (72) while the cable (3b) is unwound from the drum (83), this moves the skid from the position (72a) (fig. 15) to position (72b) (fig. 16). When the cable motorization rotates counterclockwise the cable (3a) unwinds from the drum (83) while the cable (3b) is wound on the drum (83) pulling the skid (72), this moves the skid to the position 72a (fig. 15).

d) Rotational movement: used in the needle clamp (5) to provide rotational movement to the pulley (51) of the clamp (5). The cable (3a) has several turns wound clockwise (considering the chassis support as the beginning and the end of the cable fixing on the pulley), the cable (3b) has several turns wound counterclockwise (considering as the beginning the support of the chassis and final cable fixing on the pulley), in the same movement one cable is wound the other cable is unwound.

The motorized dosing system (9) is located in the injector backpack (6) as we can see in figure 2, in charge of supplying through the tube (913) (fig. 17) the exact amount of medicine to the extension cord (72) that injects the animal. The central computer (7) ensures that the motorized dosing system transports the amount of medicine stored in the tank (99) at the necessary speed and pressure, by means of the movement of the plunger (93) of the syringe. Cyclically perform a full syringe load and then exact dosages of medication until completely emptied. Mechanical operation of the motorized dosing system:

Divided in two parts:

a) Syringe loading: when moving the moving plate (914) (fig. 13) to its position closest to the motor (92), move the syringe plunger (93) up inside the syringe tube (95) , creating a suction force (fluid towards the syringe). This suction force will be transmitted by the tube (98) to the union (912) (valve 910 outlet B) and valve (911 inlet C) (fig. 17 and fig. 18). The valve (911) does not allow the passage in direction (C to D) towards the syringe extension, the valve (910) allows the passage of fluid from the tank (99) in direction (A to B) to the syringe, filling the tube (95) of the syringe.

b) Syringe discharge: moves the moving plate (914) in the opposite direction to the motor, it is necessary for the syringe plunger (93) to move down inside the tube (95) and remove the exact amount of medicine. This pressure is transmitted through the tube (98) to the union (B) of the valve (910) and (C) of the valve (911). The valve (910) does not allow the passage in the direction (B to A) to the tank (99), the valve (911) allows the passage in the direction (C to D) through the tube (913) to the extension (7) of the injector gun (4).

The marking system (104) (fig. 3) is the mechanism to temporarily paint injected animals, necessary to distinguish those that have been medicated from those that have not. After the injection into the animal, the central computer activates the paint pressurization means through the injectors (101) (fig. 8) that are in the front protection (23a) (23b).

The disinfection / sterilization system (fig. 3) is located inside the front protection (23a) (23b) and is in charge of applying the product on the needle (1) used to sterilize it. The application of the product for disinfection / sterilization will be carried out evenly along the entire needle (1) by the necessary mechanical means.
