Zusatz zum Patente Λϊ 67911 vom 23. Juli 1892.Addendum to patents Λϊ 67911 from July 23, 1892.
Patentirt im Deutschen Reiche vom 23. April 1893 ab. Längste Dauer: 22. Juli 1907.Patented in the German Empire on April 23, 1893. Longest duration: July 22, 1907.
Die Erfindung betrifft eine Ausführungsform der unter Nr. 67911 patentirten aseptischen Glasspritze und hat den Zweck, den zugleich mit Boden und Konus gegossenen oder geblasenen Spritzencylinder durch einen solchen zu ersetzen, welcher an beiden Enden gleichartig mit einem hochstehenden Rand versehen ist. Durch diese beiden Ränder werden auf dem Cylinder frei verschiebbare Fassungsringe gehalten, die zur Verschraubung der die Kolbenstange führenden Verschlufskappe einerseits und des nun ebenfalls aufzuschraubenden Spitzenstückes andererseits dienen. Die Herstellung des Spritzencylinders wird dadurch wesentlich vereinfacht. Wenn für Kolben der im Anspruch 2. des Haupt-Patentes genannten Art als Packungsstoff z. · B. Asbestfaser oder ein ähnlicher Stoff benutzt wird, so werden nach der vorliegenden Neuerung zwischen dem Asbest Scheiben aus einem Stoff angeordnet, der Flüssigkeit leicht aufsaugt und ein elastisches Anpressen der Kolbenpackung an den Cylinder herbeiführt.The invention relates to an embodiment of the aseptic patented under No. 67911 Glass syringe and has the purpose of being cast or blown at the same time with base and cone Replace the syringe cylinder with one that is identical at both ends is provided with a raised edge. These two edges will open up the cylinder held freely movable mounting rings, which are used to screw the piston rod leading closure cap on the one hand and the tip piece that is now also to be screwed on on the other hand serve. This makes the manufacture of the syringe barrel essential simplified. If for pistons of the type mentioned in claim 2 of the main patent as packing material z. · B. Asbestos fiber or a similar material is used, according to the present innovation arranged between the asbestos washers made of a fabric, the liquid easily sucks up and an elastic pressing of the piston packing against the cylinder brings about.
Auf beiliegender Zeichnung ist:The attached drawing shows:
Fig. ι die Ansicht der Spritze,Fig. Ι the view of the syringe,
Fig. 2 ein Längsschnitt durch dieselbe undFig. 2 is a longitudinal section through the same and
Fig. 3 ein Schnitt durch eine etwas geänderte Ausführungsform des Spritzenkolbens.3 shows a section through a somewhat modified embodiment of the syringe plunger.
Der Spritzencylinder α erhält an beiden Enden je einen hochstehenden Rand a1 bezw. α2, gegen welche sich die auf dem Cylinder frei verschiebbaren Fassungsringe b b2 legen, die zur Verschraubung der der Kolbenstange e als Führung dienenden Verschlufskappe c bezw. der Hülse des Spitzenstückes f mit Aufsengewinde versehen sind. Zur Reinigung bezw. Desinficirung der Spritze ist nur nöthig, die Kappe c und das Spitzenstück f abzuschrauben; die Ringe b b2 bleiben auf dem Cylinder, auf dem sie lose hin- und hergeschoben werden können.The syringe cylinder α is given an upstanding edge a 1 respectively at both ends. α 2 , against which the freely displaceable mounting rings bb 2 lie on the cylinder, the locking cap c respectively for screwing the piston rod e serving as a guide. the sleeve of the tip piece f are provided with an external thread. For cleaning respectively. It is only necessary to disinfect the syringe by unscrewing the cap c and the tip piece f ; the rings bb 2 remain on the cylinder, on which they can be pushed back and forth loosely.
Der Kolben, welcher nach Anspruch 2. des Haupt-Patentes aus Packungsmaterial gebildet wird, das zwischen auswechselbaren Theilen ij Platz findet, erhält nach der vorliegenden Neuerung auf die Zapfen der Theile aufgesetzte Zwischenscheiben k aus einem Stoff, welcher lockerer ist und die Flüssigkeit leichter und energischer ansaugt, als der sonstige Packungsstoff. Auf diese Weise wird der Packungsstoff zum dichten Anschlufs an den Spritzencylinder gebracht. Der hochstehende Rand α2 am Ende des Spritzencylinders ist dabei gleichzeitig Veranlassung, dafs bei unbenutzter Spritze der lockere Stoff der Scheiben k in den weiteren Cylindertheil tritt, so dafs der Kolben lockerer und dadurch dichter und aufsaugungsfähiger bleibt.The piston, which according to claim 2 of the main patent is formed from packing material which is placed between exchangeable parts ij , has, according to the present innovation, intermediate disks k made of a material which is looser and the fluid is lighter and which is placed on the pins of the parts sucks in more vigorously than the rest of the packing material. In this way the packing material is brought to the tight connection to the syringe cylinder. The protruding edge α 2 at the end of the syringe cylinder is at the same time the reason that when the syringe is not in use, the loose material of the disks k enters the further part of the cylinder, so that the plunger remains looser and therefore denser and more absorbent.
