DESCRIPCIONDESCRIPTION
Dispositivo para la anestesia de animales mediante inhalacion, en particular de lechonesDevice for anesthesia of animals by inhalation, in particular piglets
La invencion hace referencia a un dispositivo para la anestesia de lechones mediante inhalacionThe invention refers to a device for anesthesia of piglets by inhalation
La anestesia de animales mediante inhalacion no solo juega un papel en la praxis veterinaria, sino de forma creciente tambien para su empleo en el campo, por ejemplo en granjas. De este modo por ejemplo para la castracion de lechones, que conforme a las normas sobre proteccion de animales mas severas no debe llevarse ya a cabo sin anestesia. Por ello al dispositivo se imponen unos elevados requisitos, en donde el mismo deberla tener una movilidad, seguridad de funcionamiento y facilidad de manejo lo mas elevadas posible.Animal anesthesia by inhalation not only plays a role in veterinary praxis, but also increasingly for use in the field, for example on farms. In this way, for example, for the castration of piglets, which according to the rules on protection of more severe animals should not be carried out without anesthesia. Therefore, the device imposes high requirements, where it should have the highest possible mobility, safety and ease of operation.
Mediante el documento DE 20 2006 013 064 se ha dado a conocer una mascara de anestesia de animales para su conexion a un sistema Bain, con cuya ayuda es posible un control optimo del gas anestesico alimentado. Ademas de esto la mascara esta equipada con una aspiracion, la cual protege al personal de servicio contra los gases anestesicos salientes.By document DE 20 2006 013 064 an animal anesthesia mask has been disclosed for connection to a Bain system, with the help of which optimal control of the fed anesthetic gas is possible. In addition to this the mask is equipped with an aspiration, which protects the service personnel against outgoing anesthetic gases.
Mediante el documento WO 2007/135248 se ha dado a conocer un dispositivo para la diagnosis medica de animales pequenos, como p.ej. ratones, sometidos a narcosis. Los animales pueden introducirse a este respecto en un cilindro que se ensancha a modo de tolva, que esta dispuesto de forma basculante sobre una unidad para el suministro de gas narcotico. Sin embargo, este dispositivo no es apropiado para intervenciones operativas en animales, en particular en animales grandes.WO 2007/135248 has disclosed a device for the medical diagnosis of small animals, such as mice, subjected to narcosis. The animals can be introduced in this respect into a cylinder that widens like a hopper, which is tilted on a unit for the supply of narcotic gas. However, this device is not suitable for operational interventions in animals, particularly in large animals.
El documento US 6,776,158 B1 describe un metodo y un dispositivo para anestesiar uno o varios animales de laboratorio. Un animal de laboratorio aislado puede anestesiarse con ello con una mascara anestesica, mientras que para varios animales se dispone de una jaula anestesica especial. El dispositivo comprende ademas un sistema para evacuar gas narcotico sobrante.US 6,776,158 B1 describes a method and a device for anesthetizing one or more laboratory animals. An isolated laboratory animal can be anesthetized with an anesthetic mask, while a special anesthetic cage is available for several animals. The device also comprises a system for evacuating excess narcotic gas.
Los aparatos conocidos hasta ahora eran relativamente complicados y caros, y la instalacion requerla determinados conocimientos tecnicos. Los elevados costes de la instalacion completa han disuadido ademas a los propietarios de animales de adquirir su propia instalacion. Por ello el objeto de la invencion consiste en producir un dispositivo de la clase citada al comienzo, que tenga un funcionamiento seguro y una manipulacion sencilla. El dispositivo deberla ademas estar construido con movilidad y lo mas modularmente posible, de tal manera que sea posible que solo tengan que transportarse las partes caras de la instalacion para la preparation y el control del gas anestesico, mientras que las restantes partes de la instalacion permanecen estacionarias, respectivamente pueden almacenarse facilmente y volver a instalarse rapidamente para su uso. Tambien para el mantenimiento regular o para una posible reparation las partes importantes de la instalacion deberlan ser muy accesibles y poder desmontarse rapidamente. Este objeto es resuelto conforme a la invencion mediante un dispositivo que presenta las caracterlsticas de la revindication 1.The devices known until now were relatively complicated and expensive, and the installation required certain technical knowledge. The high costs of the complete installation have also deterred the owners of animals from acquiring their own installation. Therefore, the object of the invention is to produce a device of the kind mentioned at the beginning, which has a safe operation and a simple manipulation. The device should also be built with mobility and as modularly as possible, so that it is possible that only the expensive parts of the facility have to be transported for the preparation and control of anesthetic gas, while the remaining parts of the facility remain stationary, respectively, can be easily stored and quickly reinstalled for use. Also for regular maintenance or for possible repair the important parts of the installation should be very accessible and can be disassembled quickly. This object is solved according to the invention by means of a device that presents the characteristics of revindication 1.
Carcasa y estacion de tratamiento forman de este modo dos componentes de la instalacion separados uno del otro, que estan unidos entre si de forma efectiva a traves de unos medios de union desmontables. La carcasa contiene los medios de preparacion caros y tecnicamente sensibles para preparar el gas anestesico, as! como los medios de control para ello necesarios. Frente a esto, la estacion de tratamiento se compone solamente de unos componentes mecanicos o electrotecnicos sencillos para el dispositivo de soporte y de la mascara anestesica, que sin embargo puede producirse tambien de forma sencilla y economica. Los medios de union desmontables se componen por un lado de los conductos flexibles para el sistema de narcosis y, por otro lado, dado el caso tambien de llneas electricas para el control de medios de manejo e indication. En el caso de un sistema de narcosis semiabierto conducen un tubo flexible de suministro a la mascara anestesica y un tubo flexible de expiration, para el aire de respiration usado, de nuevo hacia fuera de la misma. En el caso de una mascara con aspiracion es necesario ademas otro tubo flexible como conducto de aspiracion. Todos los conductos flexibles necesarios pueden conectarse de forma preferida con acoplamientos de cierre rapido a la carcasa o a los respectivos componentes del aparato, de tal manera que sea posible una instalacion rapida.Housing and treatment station thus form two components of the installation separated from each other, which are effectively connected to each other through removable joining means. The housing contains expensive and technically sensitive preparation means for preparing anesthetic gas as well! as the necessary means of control. Faced with this, the treatment station consists only of simple mechanical or electrotechnical components for the support device and the anesthetic mask, which however can also be produced in a simple and economical way. The removable joining means are made up on one side of the flexible ducts for the narcosis system and, on the other hand, in the case also of electric lines for the control of handling and indication means. In the case of a semi-open narcosis system they lead a flexible supply tube to the anesthetic mask and a flexible expiration tube, for the used breathing air, again out of it. In the case of a mask with aspiration, another flexible tube is also necessary as a suction duct. All the necessary flexible conduits can be connected preferably with quick-close couplings to the housing or to the respective components of the apparatus, such that a quick installation is possible.
La carcasa esta configurada de forma preferida como carcasa portatil, que puede montarse por ejemplo sobre una mesa. Esta fabricada de forma preferida con chapa de acero y es suficientemente robusta para proteger los medios de preparacion y medios de control sensibles contra golpes y choques, pero tambien contra impurezas. Un propietario de animales puede compartir la carcasa con la unidad de suministro con otros propietarios de animales, o puede alquilar la misma. Esto tiene la ventaja de que, por un lado, no tiene hacer frente a unas inversiones elevadas y de que, por otro lado, no tiene que ocuparse del mantenimiento y de la reparacion del aparato. El propietario de animales solo adquiere la estacion de tratamiento, en donde los costes de adquisicion son relativamente bajos. En caso necesario la estacion de tratamiento se une rapidamente a la carcasa y de este modo esta lista para usarse. Sin embargo, tambien en la praxis veterinaria el modo constructivo modular de la instalacion tiene unas ventajas considerables. De este modo pueden desmontarse rapidamente las diferentes partes de la instalacion y por ejemploThe housing is preferably configured as a portable housing, which can be mounted, for example, on a table. It is preferably manufactured with sheet steel and is robust enough to protect the preparation means and sensitive control means against shocks and shocks, but also against impurities. An animal owner can share the carcass with the supply unit with other animal owners, or he can rent it. This has the advantage that, on the one hand, it does not have to cope with high investments and that, on the other hand, it does not have to deal with the maintenance and repair of the apparatus. The animal owner only acquires the treatment station, where the acquisition costs are relatively low. If necessary, the treatment station quickly attaches to the housing and is thus ready for use. However, also in the veterinary practice the modular construction mode of the installation has considerable advantages. In this way you can quickly disassemble the different parts of the installation and for example

alojarse en un vehlcuio. Un veterinario puede transportar de este modo sin mas toda la instalacion tambien en un vehlculo pequeno.Stay in a vehicle. A veterinarian can transport in this way without more the entire installation also in a small vehicle.
Los medios de preparacion en la carcasa presentan ventajosamente un evaporador para vaporizar un anestesico llquido, que esta unido a traves de un medidor de flujo a una abertura de entrada de gas en la carcasa. Como anestesico se utiliza ventajosamente isoflurano, del que en el evaporador se obtiene gas anestesico mediante la alimentacion de oxlgeno. Con este fin se conecta a la abertura de entrada de gas una botella de oxlgeno y precisamente tambien a traves de un medio de conexion facilmente desmontable. En el medidor de flujo puede ajustarse la alimentacion de oxlgeno segun las condiciones deseadas. Basicamente serla tambien posible una mezcla con otros gases anestesicos, como p.ej. gas hilarante.The preparation means in the housing advantageously have an evaporator for vaporizing a liquid anesthetic, which is connected through a flow meter to a gas inlet opening in the housing. As an anesthetic, isoflurane is advantageously used, from which in the evaporator anesthetic gas is obtained by feeding oxygen. To this end, a bottle of oxygen is connected to the gas inlet opening and precisely also through an easily removable connection means. The oxygen supply can be adjusted in the flow meter according to the desired conditions. Basically, a mixture with other anesthetic gases, such as hilarious gas, would also be possible.
En la carcasa esta dispuesta ademas al menos una bomba para aspirar gas anestesico que sale de la mascara anestesica, en donde la bomba esta unida en el lado de presion a una abertura de salida de gas sobre la carcasa. La abertura de salida de gas esta conectada o puede conectarse tambien con unos medios de conexion facilmente desmontables a un tubo flexible, que conduce por ejemplo a un lugar en la atmosfera muy alejado del personal de servicio. En el caso de la bomba puede tratarse por ejemplo de una bomba de membrana o de otro tipo de bomba sencillo, en donde la bomba esta unida en el lado de aspiracion a una abertura de aspiracion sobre la carcasa, a la que esta fijado de forma desmontable un tubo flexible que conduce a una mascara anestesica.In the housing there is also arranged at least one pump to aspirate anesthetic gas leaving the anesthetic mask, where the pump is attached on the pressure side to a gas outlet opening on the housing. The gas outlet opening is connected or can also be connected with easily removable connection means to a flexible tube, which leads for example to a place in the atmosphere far away from service personnel. In the case of the pump, for example, it may be a membrane pump or another type of single pump, where the pump is attached on the suction side to an aspiration opening on the housing, to which it is fixed so Detachable flexible tube that leads to an anesthetic mask.
Los medios de control presentan de forma preferida al menos una valvula magnetica, con la que puede controlarse clclicamente la alimentacion de gas anestesico hasta la estacion de tratamiento. De este modo solo fluye gas anestesico hasta la estacion de tratamiento, si se necesita alll. Tambien es posible una interruption inmediata de la alimentacion a traves de la al menos una valvula magnetica.The control means preferably have at least one magnetic valve, with which the supply of anesthetic gas to the treatment station can be controlled cyclically. In this way only anesthetic gas flows to the treatment station, if needed there. It is also possible an immediate interruption of the feed through the at least one magnetic valve.
De forma particularmente ventajosa en la carcasa esta dispuesto un contador, con el que puede contarse la cantidad de gas anestesico usado y/o el numero de ciclos de anestesia. Este contador no solo se usa para establecer las horas de funcionamiento totales del aparato, sino tambien para establecer la intensidad de utilization de un usuario individual. Con base en la medicion en el contador puede fijarse por ejemplo un precio para el alquiler.Particularly advantageous in the housing is a meter, with which the amount of anesthetic gas used and / or the number of anesthesia cycles can be counted. This counter is not only used to establish the total operating hours of the device, but also to establish the intensity of utilization of an individual user. Based on the meter's measurement, for example, a rental price can be set.
La carcasa esta dividida a este respecto ventajosamente al menos en dos camaras, en donde en una camara que puede cerrarse y/o precintarse esta dispuesto al menos el contador. De este modo se impiden manipulaciones en el contador. Sin embargo, de forma preferida estan alojados en la camara cerradiza otros componentes, como p.ej. el mando de regulation o las valvulas magneticas. En la camara de libre acceso estan dispuestos el evaporador y el medidor de flujo.In this respect, the housing is advantageously divided into at least two chambers, where at least one meter is disposed in a chamber that can be closed and / or sealed. This prevents tampering with the counter. However, other components, such as the regulation knob or the magnetic valves, are preferably housed in the lock chamber. The evaporator and the flow meter are arranged in the free access chamber.
El dispositivo de soporte presenta ventajosamente un bastidor y una plataforma de soporte, a la que esta fijada de forma desmontable y preferida la mascara anestesica para animales. Sobre la plataforma de soporte puede colocarse de tal manera el animal a tratar, que la mascara anestesica haga un contacto lo mas estanco posible con la zona del hocico. Como se ha descrito en el documento de modelo de utilidad citado al comienzo, mediante la introduction del hocico en la mascara anestesica se acciona mecanicamente una valvula de control.The support device advantageously has a frame and a support platform, to which the anesthetic mask for animals is detachably and preferably fixed. The animal to be treated can be placed on the support platform, so that the anesthetic mask makes a contact as tight as possible with the snout area. As described in the utility model document cited at the beginning, a control valve is mechanically actuated by the introduction of the snout into the anesthetic mask.
Sobre el bastidor estan dispuestos de forma preferida tambien unos medios de conmutacion y control para controlar y monitorizar un ciclo de anestesia. El manejo se realiza de este modo de forma particularmente sencilla directamente en el lugar del tratamiento. En el caso de los medios de conmutacion puede tratarse a este respecto de interruptores de presion, de basculamiento o incluso de contacto. Los medios de control pueden ser sencillas lamparas indicadoras o sin embargo tambien pantallas de cristal llquido, que indican por ejemplo en forma de una visualization el estado de funcionamiento.Switching and control means are also preferably arranged on the frame for controlling and monitoring an anesthesia cycle. The handling is carried out in this way in a particularly simple way directly at the treatment site. In the case of the switching means, pressure, tilt or even contact switches can be treated in this regard. The control means can be simple indicator lamps or nevertheless also liquid crystal screens, which indicate, for example, in the form of a visualization of the operating state.
Puede conseguirse otra ventaja si en un tubo flexible que conduce a la mascara anestesica esta dispuesta una bolsa respiratoria, que esta fijada de forma desmontable a la carcasa con un estribo de sujecion. Se sabe que practicamente todos los sistemas de narcosis estan equipados con bolsas respiratorias para monitorizar la respiration. Esto es tambien aplicable al sistema Bain semiabierto, cuyo modo de funcionamiento es conocido por el experto en narcosis y que no se describe aqul con mas detalle. La fijacion de la bolsa respiratoria con ayuda del estribo de sujecion a la carcasa tiene la ventaja de que la bolsa respiratoria puede verse bien y esta posicionada de tal manera, que no se obstaculiza por descuido un funcionamiento.Another advantage can be achieved if a respiratory bag is arranged in a flexible tube leading to the anesthetic mask, which is detachably attached to the housing with a clamping bracket. It is known that virtually all narcosis systems are equipped with respiratory bags to monitor respiration. This is also applicable to the semi-open Bain system, whose mode of operation is known to the expert in narcosis and is not described here in more detail. The fixation of the respiratory bag with the aid of the clamping bracket to the housing has the advantage that the respiratory bag can look good and is positioned in such a way that it is not hindered by careless operation.
Para el tratamiento de tipo trabajo en cadena de animales es ventajoso que la estacion de tratamiento presente al menos dos dispositivos de soporte y que cada mascara anestesica este unida a la carcasa a traves de una union por tubo soporte aparte. Como se ha descrito anteriormente una union por tubo flexible puede presentar a este respecto varios tubos flexibles individuales, concretamente para el suministro de gas anestesico y para la aspiracion de gas anestesico saliente en la mascara anestesica.For the treatment of animal chain work it is advantageous that the treatment station has at least two support devices and that each anesthetic mask is attached to the housing through a separate support tube joint. As described above, a flexible tube joint can in this respect have several individual flexible tubes, specifically for the supply of anesthetic gas and for the aspiration of outgoing anesthetic gas in the anesthetic mask.
La carcasa y la estacion de tratamiento forman dos componentes de la instalacion separados o separables uno del otro. De este modo es por ejemplo tambien posible reequipar la estacion de tratamiento rapidamente para el tratamiento de otros animales y/o sustituir los medios de preparation o los medios de control.The housing and the treatment station form two components of the installation separated or separable from each other. In this way it is also possible, for example, to retrofit the treatment station quickly for the treatment of other animals and / or replace the preparation means or the control means.
En el caso de los medios de union se trata de medios de union flexibles, es decir, de tubos flexibles o cables. La 5 manipulation de los componentes de la instalacion se facilita de este modo considerablemente.In the case of the joining means, these are flexible joining means, that is, flexible pipes or cables. The manipulation of the components of the installation is thus considerably facilitated.
En el caso de la carcasa no es imprescindible, de forma visible, que se trate de una carcasa completamente cerrada. Tambien puede estar parcialmente abierta, de tal manera que determinados componentes sigan siendo facilmente accesibles en todo momento. En el caso de la carcasa podrla tratarse tambien solamente de un modulo de bastidor, que aloje todos los componentes fundamentales de los medios de preparacion y de los medios de control. Pueden 10 conseguirse ventajas adicionales si la carcasa y la estacion de tratamiento estan dispuestas sobre un bastidor comun, en particular sobre un carro rodante. Todo el dispositivo forma con ello una unidad movil, que sin embargo puede descomponerse en sus componentes principales. A este respecto la carcasa puede estar tambien integrada total o parcialmente en el bastidor.In the case of the housing, it is not essential, visibly, that it be a completely enclosed housing. It may also be partially open, so that certain components remain easily accessible at all times. In the case of the housing, it could also be only a rack module, which houses all the fundamental components of the preparation means and the control means. Additional advantages can be achieved if the housing and the treatment station are arranged on a common frame, in particular on a rolling car. The entire device thus forms a mobile unit, which however can be broken down into its main components. In this respect, the housing can also be fully or partially integrated in the frame.
En el bastidor puede estar dispuesto ademas un pulsador de pie, con el que pueden accionarse los medios de 15 control.In addition, a foot switch can be arranged on the frame, with which the control means can be operated.

respiratoria estan asociados de forma preferida a la estacion de tratamiento 5, en donde serla sin embargo concebible tambien sin mas que la misma estuviese asociada a la carcasa 2.They are preferably associated to the treatment station 5, where it is conceivable, however, also without being associated with the housing 2.
Los dos dispositivos de soporte 6, 6' con las mascaras anestesicas 7, 7' asociadas a los mismos se designan a continuacion con A y B, tambien con relacion al guiado de conductos electrico y al neumatico.The two support devices 6, 6 'with the anesthetic masks 7, 7' associated therewith are designated below with A and B, also in relation to the guidance of electrical and pneumatic conduits.
La figura 2 muestra una representacion lateral del dispositivo de soporte 6 y de la estacion de tratamiento 5 conforme a la figura 1, en donde pueden verse tambien detalles adicionales en las figuras 3 y 9. El bastidor basico 20 del dispositivo de soporte 6 se compone de los dos perfiles de apoyo 39 y 39' paralelos y con seccion transversal aproximadamente rectangular, los cuales estan unidos entre si a traves de dos travesanos 40. Sobre cada uno de los dos travesanos esta dispuesta respectivamente una plataforma de soporte, inclinada formando un angulo con los mismos. La plataforma de soporte esta configurada por ejemplo a modo de bandeja y su angulo de inclinacion puede ser tambien ajustable en caso necesario. Al extremo situado mas debajo de la plataforma de soporte esta fijada de forma desmontable una mascara anestesica 7. Hasta cada mascara conduce un tubo flexible de suministro 4l para gas anestesico. El mismo esta dispuesto concentricamente dentro de un tubo flexible de expiracion 44 con un diametro mayor. A traves de este ultimo se evacua el aire de respiracion expulsado del animal. Hasta la mascara 7 conduce ademas un tubo flexible de aspiracion 15. Del documento de modelo de utilidad citado anteriormente pueden deducirse detalles de la funcion de la mascara.Figure 2 shows a side representation of the support device 6 and the treatment station 5 according to Figure 1, where additional details can also be seen in Figures 3 and 9. The basic frame 20 of the support device 6 is composed of the two support profiles 39 and 39 'parallel and with approximately rectangular cross-section, which are connected to each other through two cross-members 40. On each of the two cross-sections there is respectively a support platform, inclined to form an angle. with them. The support platform is configured for example as a tray and its angle of inclination can also be adjusted if necessary. An anesthetic mask 7 is removably attached to the end located below the support platform. A flexible supply tube 4l for anesthetic gas conducts to each mask. It is arranged concentrically within a flexible expiration tube 44 with a larger diameter. Through the latter the breathing air expelled from the animal is evacuated. Even a flexible suction tube 15 leads to the mask 7, and details of the function of the mask can be deduced from the utility model document mentioned above.
Esta previsto sobre el perfil de apoyo 39 para cada estacion A y B un interruptor para conectar el dispositivo y un interruptor 23 para desconectar el dispositivo.

In the second chamber, for example, the command 30 is arranged with a counter 17 to count the anesthesia cycles. Also the magnetic valves 16, 16 'for controlling the gas supply are advantageously housed in the second chamber 19.
Con base en la figura 5 se describe a continuacion con mas precision el control neumatico del sistema de narcosis. Desde una botella de oxlgeno 34 se alimenta oxlgeno al medidor de flujo 10 a traves de una unidad manometrica 33, una valvula principal 32 y una valvula de sobrepresion 31. En el mismo puede ajustarse la cantidad de gas deseada con un boton giratorio. El oxlgeno conduce hasta el evaporador 9, en el que se vaporiza el isoflurano llquido de un modo y de una manera no descritos aqul con mas detalle. Desde el evaporador 9 el gas narcotico conduce hasta las dos valvulas magneticas 16, 16', que regulan la alimentacion hasta las dos mascaras anestesicas 7 y 7' en las estaciones A y B. La aspiracion del gas anestesico saliente a traves de los dos conductos de aspiracion 15, 15' se realiza con las dos bombas 12, 12', las cuales conducen ambas en el lado de presion al conducto de gas de escape 42.Based on Figure 5, the pneumatic control of the narcosis system is described below with more precision. From an oxygen bottle 34, oxygen is fed to the flow meter 10 through a manometric unit 33, a main valve 32 and an overpressure valve 31. The desired amount of gas can be adjusted therewith with a rotary knob. The oxygen leads to evaporator 9, in which the liquid isoflurane is vaporized in a manner and in a manner not described here in more detail. From the evaporator 9, the narcotic gas leads to the two magnetic valves 16, 16 ', which regulate the supply to the two anesthetic masks 7 and 7' at stations A and B. The aspiration of the outgoing anesthetic gas through the two ducts suction 15, 15 'is carried out with the two pumps 12, 12', which both lead on the pressure side to the exhaust gas duct 42.
El control electrico se ha representado de forma simplificada en un esquema conforme a la figura 6. El suministro de corriente se realiza a traves de una tension de red normal de 230 voltios, que se acopla al interruptor principal 48. A traves de un transformador 49 y a traves de un seguro de control 50, una corriente de control de 2A llega al mando de regulation 30. Al mismo esta conectada una lampara de control roja 46, la cual indica un mantenimiento requerido. En el interruptor 47 puede activarse la aspiracion con ayuda de las bombas 12 y 12'. A traves del mando de regulacion se controlan tambien las dos valvulas magneticas 16, 16' para la liberation del gas anestesico as! como la valvula principal 32. Por ultimo el mando 30 contiene el contador 17 para contar la cantidad de gas y/o losThe electrical control is represented in a simplified way in a scheme according to figure 6. The power supply is carried out through a normal mains voltage of 230 volts, which is coupled to the main switch 48. Through a transformer 49 and through a control lock 50, a control current of 2A reaches the control knob 30. A red control lamp 46 is connected thereto, which indicates a required maintenance. In the switch 47 the suction can be activated with the help of the pumps 12 and 12 '. The two magnetic valves 16, 16 'for the release of the anesthetic gas as well are controlled through the regulating control! as the main valve 32.
