Abstract

The surgical syringe has a cylindrical body (1) which houses a piston which is operated to eject the contents of the syringe through the needle attached to the end of the body. The needle is protected from accidental damage by a sliding open ended tube (2). This tube (2) can be extended beyond the outer end of the needle so that the needle is protected until the syringe is used. This method of protection is also applicable to cannulae and similar surgical instruments. USE - Surgical syringes with protective tube.

Description

Vorrichtung zum Schutze vor Verletzungen durch Spritzen mit Nadeln, Kanülen oder Düsen aller Art insbesondere im medizinischen Bereich.Device to protect against injuries from spraying with needles, cannulas or nozzles of all kinds in particular in health care.

Spritzen in verschiedenen Ausführungen sind seit langem bekannt.Syringes in various designs have been around for a long time known.

Bisher existiert jedoch keine Vorrichtung zum Schutze vor Verletzungen durch Spritzen, die angesichts der massen­ haften Verwendung von Spritzen vor allem im medizinischen Bereich genügend einfach und billig ist.So far, however, there is no protective device Injuries from injections given the mass stick use of syringes especially in medical Area is simple enough and cheap.

Der in Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, einen gleichzeitig billigen, leicht zu hand­ habenden und absolut sicheren Schutz vor Verletzungen durch Spritzen zu erreichen.The invention specified in claim 1 is the problem based on a cheap, easy to handle having and absolutely safe protection against injuries To achieve syringes.

Der Vorteil der Erfindung liegt unter anderem darin, daß die Schutzvorrichtung sowohl an Wegwerfspritzen, als auch an mehrmals zu verwendenden Spritzen aller Art angebracht werden kann und dabei eine zuverlässige Vermeidung von Verletzungen und somit bei Verwendung im medizinischen Bereich eine Erniedrigung der Infektionsgefahr für Ärzte und Pflegepersonal gewährleistet.The advantage of the invention is, inter alia, that the protection device on disposable syringes as well attached to multiple use syringes of all kinds can be and thereby a reliable avoidance of Injuries and thus when used in medical Area a reduction in the risk of infection for doctors and nursing staff guaranteed.

Eine vorteilhafte Ausgestaltung der Erfindung ist in Anspruch 2 angegeben. Die Weiterbildung nach Anspruch 2 ermöglicht es, Nadel und Röhre gefahrlos vom Zylinder der Spritze zu trennen und wieder anzufügen.An advantageous embodiment of the invention is in Claim 2 specified. The further training according to claim 2 allows the needle and tube to be safely removed from the cylinder Disconnect syringe and reattach.

Ein Ausführungsbeispiel ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben. Es zeigtAn embodiment is shown in the drawings and is described in more detail below. It shows

Fig. 1 die Vorrichtung nach Anspruch 1, Fig. 1 shows the apparatus according to claim 1,

Fig. 2 die Vorrichtung nach Anspruch 2. Fig. 2 shows the device according to claim 2.

Nach Anspruch 1 wird der Spritzenzylinder (1) in eine konzentrische, paßgerechte Röhre (2) aus geeignetem Material, z. B. Plastik oder Glas, eingeführt. Unter Um­ ständen ist eine Führschiene anzubringen. Die auf dem Zylinder verschiebbare Röhre kann so weit nach vorne ge­ schoben werden, daß ihr Rand über die Spitze der Nadel reicht. Um zu verhindern, daß die Röhre auf dem Zylinder zurückrutscht, könnte unter anderem eine Feder oder ein halbelastischer Plastikknopf auf dem Zylinder oder der Röhre angebracht werden. Der Plastikknopf (3) könnte in einer Rille laufen, die am Ende eine kleine, passende Vertiefung enthält.According to claim 1, the syringe barrel ( 1 ) in a concentric, fitting tube ( 2 ) made of a suitable material, for. B. plastic or glass introduced. A guide rail must be attached under conditions. The slidable tube on the cylinder can be pushed so far forward that its edge extends over the tip of the needle. To prevent the tube from slipping back on the cylinder, a spring or a semi-elastic plastic button could be attached to the cylinder or tube, among other things. The plastic button ( 3 ) could run in a groove that contains a small, matching recess at the end.

Nach Anspruch 2 wird die Nadel (1) in einer Scheibe (2), die fest in einen Zylinder (3) eingeschweißt ist, ver­ ankert. Über die Vorrichtung wird die Röhre (4) geschoben. Die Vorrichtung wird dann - z. B. mit einem Bajonettver­ schluß - auf dem überstehenden Rand des Hauptzylinders (5) befestigt. Die Nadel wird dabei gleichzeitig über den Stutzen (6) am Zylinderkopf des Hauptzylinders geschoben. Der Zylinder mit der in ihm befestigten Nadel läßt sich nach Gebrauch gefahrlos vom Hauptzylinder lösen. Das untere Ende der Nadel ist durch eine geeignete Vorrichtung, etwa durch einen Wulst oder durch einen Plastikring, geschützt.According to claim 2, the needle ( 1 ) is anchored ver in a disc ( 2 ) which is welded firmly into a cylinder ( 3 ). The tube ( 4 ) is pushed over the device. The device is then - e.g. B. with a bayonet lock - attached to the protruding edge of the master cylinder ( 5 ). The needle is pushed simultaneously over the socket ( 6 ) on the cylinder head of the master cylinder. The cylinder with the needle attached to it can be safely removed from the master cylinder after use. The lower end of the needle is protected by a suitable device, such as a bead or a plastic ring.

Claims (2)

1. Vorrichtung zum Schutze vor Verletzungen durch Spritzen mit Nadeln, Kanülen oder Düsen aller Art insbesondere im medizinischen Bereich, dadurch gekennzeichnet, daß eine Röhre aus geeignetem Material über den Zylinder, an dem die Nadel befestigt ist, geschoben wird, und zwar so, daß sie konzentrisch zur Nadel über den Zylinderrand gezogen werden kann, bis ihr Rand über der Spitze der Nadel steht. In dieser Stellung kann die Röhre in geeigneter Weise befestigt werden.1. Device for protection against injuries by spraying with needles, cannulas or nozzles of all kinds, in particular in the medical field, characterized in that a tube made of suitable material is pushed over the cylinder to which the needle is attached, in such a way that it can be pulled concentrically to the needle over the edge of the cylinder until its edge is above the tip of the needle. In this position the tube can be attached in a suitable manner. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Nadel in der Trennscheibe eines zweiten Zylinders verankert wird, der derart auf dem Haupt­ zylinder angebracht wird, daß die Nadel im Nadelstutzen auf dem Hauptzylinder festsitzt, und zwar so, daß Röhre und Nadel nach Gebrauch vom Hauptzylinder gelöst werden können.2. Device according to claim 1, characterized, that the needle in the cutting disc of a second Cylinder is anchored in such a way on the main cylinder is attached that the needle in the needle socket stuck on the master cylinder in such a way that Tube and needle detached from master cylinder after use can be.
