Abstract

The device has a transparent guard cylinder that is manufactured from glass, metal or plastic in different colors. The guard cylinder is formed as a cylinder with a scale for amount of liquid to be provided. The guard cylinder has knurling on circumference for an enhancement of grip traction and haptics. The guard cylinder is pushed forward toward a needle tip, and comprises an inner axial guide, and firmly integrated detent dots and guide for a protective sheath that is threaded over the needle and pushed toward pistons.

Description

Die Erfindung betrifft eine Nadelschutzvorrichtung für medizinische Spritzen, welche ungewollte Einstiche sicher verhindert. Die Aufgabe des Schutzzylinders besteht darin den Anwender vor infektiösen Krankheiten zu bewahren, darüber hinaus die Funktion kostengünstig zu realisieren. Zur Lösung dieser Aufgaben bietet die Erfindung folgende sichere Vorgehensweise an.The invention relates to a needle protection device for medical syringes, which reliably prevents unwanted punctures. The task of the protective cylinder is to protect the user against infectious diseases, moreover, to realize the function cost-effectively. To solve these problems, the invention offers the following safe procedure.

Zuerst muss die Schutzhülle wie bekannt von der Nadel abgezogen werden. Im Anschluss daran kann die Spritze durch zurückziehen des Kolbens wie allgemein üblich aufgezogen werden (6). Dann kann die Spritze durch eindrücken des Kolbens wie bekannt und üblich injiziert werden (7). Daraufhin kann die Nadel der Spritze wie bekannt aus der Vene beziehungsweise aus dem Körper des Empfängers gezogen werden.First, the protective cover must be removed from the needle as known. Following this, the syringe can be pulled open by pulling back the plunger as usual ( 6 ). Then the syringe can be injected by pushing in the piston as known and usual ( 7 ). Then, as is known, the needle of the syringe can be pulled out of the vein or out of the body of the recipient.

An dieser Stelle greift die Erfindung. Im Folgenden wird der Schutzzylinder über einen bestimmten Hub aus der Anfangsposition (5) in die Endposition (8) geschoben. Das Vorschieben des Schutzzylinders ist durch eine formschlüssige Führungsschiene (8) ermöglicht. Die Anfangs- und Endlage ist durch Rastnasen an dem Zylinder gewährleistet. Nachdem der Schutzzylinder in seine Endlage geschoben wurde, ist kein Einstich mehr möglich. Darüber hinaus sind die Finger des Anwenders beim Ausführen des Hubes des Schutzzylinders in sicherer Entfernung von der Nadel. Damit die Finger des Anwenders beim Vorschieben des Schutzzylinders zusätzlich gesichert sind, ist auf dem äußeren Durchmesser eine Rändelung/Riffelung (5) angebracht. Nachdem die Nadel mit dem Schutzzylinder gesichert ist, kann die Spritze problemlos entsorgt werden (8). Zusätzlich kann noch die Schutzhülle durch die vordere Führungsbuchse des Schutzzylinders gefahrlos aufgeschoben werden (9). Die Schutzhülle wird durch die vordere Führungsbuchse in axialer Richtung geführt. Die Schutzhülle kann sich im Schutzzylinder ebenfalls nicht verkanten.At this point the invention applies. In the following, the protective cylinder is moved over a certain stroke from the initial position ( 5 ) into the end position ( 8th ) pushed. The advancement of the protective cylinder is by a positive guide rail ( 8th ). The initial and final position is ensured by locking lugs on the cylinder. After the protective cylinder has been pushed into its end position, no puncture is possible. In addition, the fingers of the user are at a safe distance from the needle when carrying out the stroke of the protective cylinder. So that the fingers of the user are additionally secured when advancing the protective cylinder, a knurling / corrugation (on the outer diameter ( 5 ) appropriate. After the needle is secured with the protective cylinder, the syringe can be disposed of easily ( 8th ). In addition, the protective cover can be pushed safely through the front guide bush of the protective cylinder ( 9 ). The protective cover is guided by the front guide bush in the axial direction. The protective cover can also not tilt in the protective cylinder.

The scale can be mounted both on the protective cylinder and on the cylinder. Der Schutzzylinder verfügt über eine Rändelung/Riffelung zur Verbesserung der Griffigkeit und Haptik, um Abrutschen der Finger beim Vorschieben des Schutzzylinders zu vermeiden. Die Rändelung ist auf dem Umfang des Schutzzylinders nur segmentiell angebracht, damit das Ablesen der Skala auf dem Zylinder gewährleistet ist. (5)The protective cylinder has a knurling / ribbing to improve the grip and feel to prevent slippage of the fingers when advancing the protective cylinder. The knurling is only applied on the circumference of the protective cylinder in a segmental manner so that the reading of the scale on the cylinder is ensured. ( 5 ) Der Schutzzylinder wird parallel zur Nadel nach vorne geschoben. Der Schutzzylinder wird in Richtung der Nadelspitze nach vorne geschoben. Das heißt in gleichläufiger Richtung und nicht zur Nadelspitze hin. (4)The protective cylinder is pushed forward parallel to the needle. The protective cylinder is pushed forward in the direction of the needle tip. This means in the same direction and not to the needle tip. ( 4 ) Der Schutzzylinder verfügt über eine innenliegende axiale Führung. Der Schutzzylinder kann auf dem Zylinder nicht verdreht werden. Als Führung können alle aus der Kunststofftechnik bekannten Möglichkeiten zum Einsatz kommen. (8)The protective cylinder has an internal axial guide. The protective cylinder can not be twisted on the cylinder. As a guide, all known from the plastics technology options can be used. ( 8th ) Der Schutzzylinder verfügt über zwei fest integrierte Rastpunkte, welche direkt an dem Schutzzylinder angebracht sind. Als Rastung/Clipsung/Schnappverbindung können alle aus der Kunststofftechnik bekannten Möglichkeiten zum Einsatz kommen. Eine Ringschnappverbindung ist beispielsweise ebenfalls möglich. (2)The protective cylinder has two permanently integrated locking points, which are attached directly to the protective cylinder. As detent / clip / snap connection all known from the plastics technology options can be used. A ring snap connection is also possible, for example. ( 2 ) Der Schutzzylinder verfügt über eine Führung (Führungsbund/-absatz) für die Schutzhülle (12). Das heißt, die Schutzhülle kann gefahrlos über die Nadel gefädelt werden und dann in Richtung des Kolben geschoben werden. Als Führung können alle aus der Kunststofftechnik bekannten Möglichkeiten zum Einsatz kommen. (9) Der Führungsbunddurchmesser muß nicht konzentrisch zum Schutzzylinderdurchmesser konzipiert werden.The protective cylinder has a guide (guide collar / shoulder) for the protective cover ( 12 ). That is, the protective cover can be safely threaded over the needle and then pushed in the direction of the piston. As a guide, all known from the plastics technology options can be used. ( 9 ) The guide collar diameter does not have to be designed concentrically to the protective cylinder diameter. Nach Einrasten des Schutzzylinders in Position 2 (Endlage) ist die Nadel geschützt.After locking the protective cylinder in position 2 (end position), the needle is protected.
