Description

Injektionsspritze. Die seit alters her in Gebrauch stehenden zylinderförmigen Injektionsspritzen mit zentral gelegenem K-anülenansatz sind in den letzten Jahren dadurch verbessert worden, daß man ihnen eine flache Basis nebst ex-i zentrischem Kanülenansatz verliehen hat. Neue Versuche haben nun dargetan, daß die so gewonnene größere Sicherheit der Auflage auf die Extremität dadurch noch in wesentlicher Weise gesteigert wird, daß man die Spritze c mit einer konkaven Basisfläche a (in Abb. i und a) versieht, die es erlaubt, die Spritze während der Injektion der Extremität mit größter Stabilität und ohne Gefahr eines seitlichen Abrutschens anzulegen. Der technische Vorteil der neuen Konstruktion wird weiter gesteigert dadurch, daß man den Kanülenansatz b in Berührung mit dem Scheitelpunkt des Basisbogens oder in unmittelbarer Nähe dieses Scheitelpunktes anbringt (vgl. Abb. a, die eine Ansicht von vorn, darstellt), was eine wesentliche Erleichterung beim Einstich in die Blutader gewährt. Gegebenenfalls sind auch Fassungsstücke der Spritze der konkaven Basisgestaltung anzupassen. Der zylindrische Innenraum der Spritze wird durch die beschriebenen Änderungen der Außenform nicht beeinflußt.Injection syringe. The cylindrical ones that have been in use since ancient times Injection syringes with a centrally located K-nozzle attachment have been used in recent years has been improved by giving them a flat base along with an ex-i centric Lent cannula hub. New experiments have now shown that the as a result, greater security of the support on the extremity is still essential it is increased that the syringe c has a concave base surface a (in Fig. i and a) provides that it allows the syringe during the injection of the limb to put on with the greatest stability and without the risk of slipping sideways. Of the The technical advantage of the new construction is further increased by the fact that one the cannula hub b in contact with the apex of the base arch or in the immediate vicinity Near this vertex (see Fig. A, which is a view from the front), which makes it much easier to puncture the blood vessel. Possibly The socket pieces of the syringe must also be adapted to the concave base design. Of the The cylindrical interior of the syringe is shaped by the changes described above unaffected.
