Description

Gerät für Massen-Injektionen, insbesondere für tierärztlichen Gebrauch Für hlassen-IIljektiolell, xvie sie z. B. in der Praxis des Tierarztes beim Auftreten von Älaul-und Klauenseuche notwendig werden sind Geräte bekannt, bei denen ein Behälter zur Aufnahme der Vakzine mit der der Injektion dienenden Spritze haulich vereinigt sind. Ein von Hand zu bedienendes oder automatisch arbeitendes Ventil sorgt dafür, daß beim Nachfüllen der Spritze aus dem Vakzinelsehälter der Weg von der Spritze zur Injektionsnadel und umgekehrt bei der Injektion der Weg von der Spritze zum Serumbehälter versperrt ist.Device for mass injections, especially for veterinary use For h Lassen-IIljektiolell, xvie they z. B. in the practice of the veterinarian when it occurs devices are known in which a container to receive the vaccine with the syringe used for the injection are. A manually operated or automatic valve ensures that that when refilling the syringe from the vaccine container the way from the syringe to the injection needle and vice versa when injecting the path from the syringe to the Serum container is blocked.

Bei bekannten Geräten dieser Art wird der Kolben der Spritze von Hand in seiner Bervegungsrichtung betätigt. Diese geradlinige Bewegung beim Füllen und Entleeren der Spritze macht eine entsprechende solide Halterung der Spritze notwendig, die aber nicht immer leicht zu erzielen ist oder aber sie zwingt den Arzt. beim Bediene der Spritze beide Hände zu gebrauchen und sich eines Gehilfen zu bedienen. Bei Geräten, die :oii Arzt selbst am Körper getragen werden, entstehen unangenehme Rutschbewegungen, und es ergibt sich eine gezwungene, rasch zur Ermüdung führende Bedienung der Spritze. Die Tiere erhalten auch je nach Größe und nach Art des verwendeten Injektionsmittels verschieden große Mengen von letzterem eingespritzt, was dadurch geschieht, daß man die Spritze entweder nur teilweise füllt oder von der ganz gefüllten Spritze nur eine entsprechende Teilmenge ausspritzt. Die Dosierung erfolgt hierbei mit Hilfe einer Skala an Kolbenstange oder Zylinder, wobei bei schlechten Sichtverhältnissen leicht Fehler entstehen und das ständige Beobachten der erwa hnten Skala den Bedienenden zusätzlich beansprucht. In known devices of this type, the plunger of the syringe is from Hand operated in its direction of movement. This straight-line movement when filling and emptying the syringe makes a corresponding solid support of the syringe necessary, but which is not always easy to achieve or it forces the Doctor. to use both hands and an assistant to operate the syringe to use. With devices that are: oii physician worn on the body, arise uncomfortable sliding movements, and there is a forced, rapid fatigue leading operation of the syringe. The animals also receive, depending on their size and type of the injection medium used, different amounts of the latter are injected, what happens by filling the syringe either partially or from the fully filled syringe only squirts out a corresponding partial amount. The dosage takes place here with the help of a scale on the piston rod or cylinder, with bad Visibility errors easily arise and the constant observation of the Erwa The operator stressed the scale additionally.

Erfindungsgemäß werden diese Übel stände dadurch heseitigt. daß die Betätigung des Kolhens der Spritze durch eine Drehbewegung, die über eine Schub- und Kolbenstange in die für den Kollien erforderliche geradlinige Bewegung umgewandelt wird, erfolgt. Ferner kann der Weg des Kolbens in Ansaugrichtung durch einen verstellbarren Anschlag verschieden groß ei,ngestellt werden. Dieser Anschlag ist zweckmäßig am feststehenden Teil der Spritze angeordnet. Auch ist dieser Anschlag so ausgebildet, daß zu seiner Verstellung das Bedienen einer Schraube, I\lutter o. dgl. nicht notwendig ist, sondern daß das L,öscn und Feststellen des Anschlages durch Federrastung erfolgt, z. B. in der Weise, daß ein unter Federdruck stehender Stift am Anschlag in eine Bohrung oder einen Schlitz am Hauptteil der Spritze einrastet. Indem man den Stift entgegen der Fetlerkraft aus der erwähnten Bohrung bzw. According to the invention, these evils are thereby eliminated. that the Actuation of the piston the syringe by rotating the Via a push and piston rod in the straight line required for the package Movement is converted takes place. Furthermore, the path of the piston can be in the suction direction can be set in different sizes by means of an adjustable stop. This The stop is expediently arranged on the stationary part of the syringe. Also this is Stop designed so that to adjust it, the operation of a screw, I \ lutter or the like is not necessary, but that the L, öscn and establishing the Stop takes place by spring detent, z. B. in such a way that a spring pressure standing pin at the stop in a hole or a slot on the main part of the The syringe locks into place. By moving the pen against the force of the Fetler mentioned Bore or

Schlitz hebt, wird der Anschlag frei und kann in eine andere Bohrung oder Schlitz eingerastet werden.If the slot is lifted, the stop is free and can be used in another hole or slot.

Ilat man den erwähnten Anschlag in eine der äeniinschten Injektionsmenge entsprechende Stellung gebracht, dann kann durch Links- und Rechtsdrehung des Handrades der Kolben zwischen seinen beiden Endstellungen - das sind der vordere Zylinderdeckel und der Anschlag - hin- und herbewegt werden, wodurch eine bestimmte Menge Vakzine dem Vorratsl>ehälter entnommen und dann der Injektionsnadel bzw. dem Tier zl,geleitet wird. The mentioned stop is inserted into one of the similar injection quantities brought the appropriate position, then by turning the handwheel to the left and right the piston between its two end positions - that is the front cylinder cover and the stop - can be moved back and forth, creating a certain amount of vaccine taken from the storage container and then passed to the injection needle or the animal will.

Abb. 1 zeigt die Seitenansicht einer beispielsweisen Ausführungsform einer derartigen Spritze, Abb. 2 zeigt die Vorderansicht. Fig. 1 shows the side view of an exemplary embodiment of such a syringe, Fig. 2 shows the front view.

Der Behälter a trägt die Hülse b mit den beiden in Abstand voneinander angeordneten Platten d. The container a carries the sleeve b with the two at a distance from each other arranged plates d.

In der Hülse b befindet sich der Glaszylinder f mit dem Kolben g. Das Handrad h sitzt auf der Achse i, welche in Bohrungen der Platten d drehbar gelagert ist. Älit der Achse i ist die Schubstange k verbunden, und diese mit dem Gabelkopf I der Kolbenstange m, die schwenkbar mit dem Kolben g verbunden ist. lrm die Achse i, aber von dieser unabhängig drehbar, sind innerhalb der beiden Platten d die zwei Anschlaghebel n angeordnet, die an ihrem freien Ende durch die Hülse o miteinander verbunden sind. Die Hebeln dienen als Anschlag für den Gabelkopf l und begrenzen so, je nach ihrer Stellung, den Weg des Kolbens g nach rückwärts (in Ansaugrichtung). Zur Feststellung der Hebel n trägt die Hülse o einen Stift p, der im Führungsbolzen q sitzt und durch die Feder r, die sich gegen die mit der Hülse o verbundene Kappe s abstützt, in der Richtung der Achse i gedrückt wird. Die Platten d sind auf der der Hülse o zugewandten Seite kreisförmig begrenzt in der Weise, daß der Kräsbogen seinen Mittelpunkt in der Achse i hat.The glass cylinder f with the piston g is located in the sleeve b. The handwheel h sits on the axis i, which is rotatably mounted in holes in the plates d is. The push rod k is connected to the axis i, and it is connected to the fork head I the piston rod m, which is pivotably connected to the piston g. Noisy the axis i, but rotatable independently of this, are the two within the two plates d Stop lever n arranged, which at their free end through the sleeve o with each other are connected. The levers serve as a stop for the fork head l and limit so, depending on their position, the path of the piston g backwards (in the suction direction). To fix the lever n, the sleeve o carries a pin p, which is in the guide pin q is seated and by the spring r, which is pressed against the cap connected to the sleeve o s is supported, is pressed in the direction of the axis i. The plates d are on the the sleeve o side facing circular bounded in such a way that the Kräsbogen has its center in the axis i.

Dieser Kreisbogen ist mit Schlitzen t versehen, in die der Stift p unter der Kraft der Feder r einrastet und so die Anschlaghebel ii in ihrer Lage festhält. Ein mit dem Bolzen q verbundener Knopf u gestattet es, den Stift p aus dem Schlitz t herauszuheben und so die Lage der Hebel zu verändern. This circular arc is provided with slots t into which the pin p engages under the force of the spring r and so the stop lever ii in its position holds on. A button u connected to the bolt q allows the pin p to be removed to lift out the slot t and thus change the position of the levers.

Je nach Lage und Zahl der Schlitze t kann man den Weg des Kolbens g verschieden halten und verschiedene Flüssigkeitsmengen in die Spritze einsaugen.Depending on the position and number of the slots t you can determine the path of the piston Hold g differently and suck different amounts of liquid into the syringe.

Die Schlitze t sind zweckmäßig mit Ziffern versehen die dem jeweiligen, durch die Anschläge n sich hierbei ergebenden Hubvolumen in irgendeiner der bekannten WIaßeinheiten entsprechen. The slots t are appropriately provided with numbers that correspond to the respective by the stops n in this case resulting stroke volume in any of the known WI units correspond.
