Description

Die Ausfilhrung der sogenannten Hochdruckanästhesie nach Prof. Kirschner ist mit einer der üblichen Injektionsspritzen nic;ht möglich, da man mit der Hand nicht den erforderlichen spezifischen Injektionsldruck erreicht. Ans diesem Grunde hat auch Kirschner Iden bekannten Druckapparat konstruiert. The execution of the so-called high pressure anesthesia according to Prof. Kirschner is not possible with one of the usual injection syringes, since you can do it with your hand does not reach the required specific injection pressure. For this reason also designed Kirschner Iden's well-known printing apparatus.

Die Hochdruckanästhesie hat gegenüber der gewöhnlichen Anästhesie folgende Vorteile: I. Bei richtiger Technik fast völlige Schmerzlosigkeit für den Patienten, Ida ein Strahl der Injektionsflüssigkeit vor der Kanüle herläuft und das getroffene Gewebe sofort unempfindlich macht; 2. schnelleres Eintreten der Anästhesie, da die durch Druck eingespritzte Flüssigkeit besser in die Gewebespalten gedrückt wird und aus diesem Grunde 3. ein geringerer Verbrauch des nicht immer unschädlichen Anästhetikums. The high pressure anesthesia has compared to the ordinary anesthesia the following advantages: I. With the right technique, almost complete painlessness for the Patient, Ida runs a jet of the injection fluid in front of the cannula and immediately makes the affected tissue insensitive; 2. faster onset of anesthesia, because the liquid injected by pressure is better pushed into the tissue crevices and for this reason 3. a lower consumption of what is not always harmless Anesthetic.

Die Hochdruckanästhesis wird mit Hilfe besonderer Druckapparate durchgeführt, die einen Injektionsdruck von etwa 3 atü erzeugen. Solche Injektionsapparate bedürfen außer der besonderen Konstruktion der Injektionsspritze einer Druckgasflasche und sind infolgedessen außerordentlich kostspielig und teuer. The high pressure anesthesia is carried out with the help of special pressure equipment, which generate an injection pressure of about 3 atmospheres. Such injection devices are required apart from the special construction of the injection syringe of a pressurized gas cylinder and as a result, are extremely costly and expensive.

Die Erfindung trägt dem dadurch Rechnung, daß die Handinjektionsspritze eine den Druck der einzuspritzenden Flüssigkeit steigernde Hydraulik aufweist. Zu diesem Zweck ist ein Stufenkolben vorgesehen, auf dessen größeren über Druckflüssigkeit ein kleinerer, von Hand zu bewegender Kolben arbeitet. The invention takes this into account in that the hand-held injection syringe a hydraulic system that increases the pressure of the liquid to be injected. to For this purpose, a stepped piston is provided, the larger of which is pressurized a smaller piston that can be moved by hand works.

Die Zeichnung zeigt eine Ausführungsform einer erfindungsgemäßen Injektionsspritze im Axialschnitt. The drawing shows an embodiment of an inventive Injection syringe in axial section.

Die Spritze besteht aus dem Zylinder I, in dem sich der von Hand zu bewegende Kolben 2 befindet. The syringe consists of the cylinder I, in which the manual piston 2 to be moved is located.

Der Kolben 2 arbeitet über in dem Zylinder I befindliche Druckflüssigkeit auf den größeren Kolben 3 eines Stufenkolbens, der in dem Zylinder 4 von größerem Durchmesser als der Zylinder I geführt ist. Dieser Zylinder 4 besitzt auf seiner dem Zylinder I abgekehrten Seite Luftaustrittsdüsen 5 und geht über in den eigentlichen Druckzylinder 6, in den sich der mit dem Kolben 3 starr verbundene, kleinere Stufenkolben 7 des Stufenaggregates 3, 7 erstreckt. Der Zylinder 6 ist unten mit dem Anschlußstutzen 8 für die Injektionsnadel 9 versehen.The piston 2 works by means of pressure fluid located in the cylinder I. on the larger piston 3 of a stepped piston, which is in the cylinder 4 of the larger Diameter as the cylinder I is guided. This cylinder 4 has on his the side facing away from the cylinder I air outlet nozzles 5 and goes into the actual Pressure cylinder 6 in which the smaller stepped piston is rigidly connected to the piston 3 7 of the stage unit 3, 7 extends. The cylinder 6 is at the bottom with the connecting piece 8 provided for the injection needle 9.

Beim Druck auf den Kolben 2 wird die in dem Behälter I befindliche Druckflüssigkeit, z. B. aus bestehend, verdrängt, und damit erfährt der größere Stufenkolben 3 eine Verschiebung.When the piston 2 is pressed, the pressure in the container I becomes Hydraulic fluid, e.g. B. consisting of, displaced, and thus the greater experiences Stepped piston 3 a shift.

Mit Idem Kolben 3 wird auch der andere Stufenkolben 7 in dem Zylinder 6 bewegt und verdrängt aus diesem Anästhetikum unter entsprechend erhöhtem Druck. Das Verhältnis der Kolben 3 und 7 kann beliebig sein; wesentlich ist lediglich, daß durch das KolJbenverhältnis und den Wegverlust ein entsprechend erhöhter Druck erzeugt wird. With Idem piston 3, the other stepped piston 7 is also in the cylinder 6 moves and displaces from this anesthetic under correspondingly increased pressure. The ratio of pistons 3 and 7 can be any; it is only essential that the piston ratio and the loss of travel result in a correspondingly increased pressure is produced.

Mit Hilfe der erfindungsgemäßen Injekt.ionsspritze läßt sich Anästhetikum ohne die Ausübung eines allzu großen Kraftaufwandes auch in härtere Gewebe ohne weiteres einspritzen, ohne daß die Gefahr einer Störung der s,icxhanschließeaden Operation besteht. With the help of the injection syringe according to the invention, anesthetic can be dispensed without exerting too much force, even in harder tissue without Inject further without the risk of disturbing the s, icxhannahmeadden Operation exists.
