Die Erfindung betrifft eine Injektionseinrichtung,The invention relates to an injection device,
Es ist bekannt, Injektionsnadeln zum kontinuierlichen oder periodischen subkutanen oder intramuskulären Einbringen einer wässrigen oder öligen Heilmittellösung in Körpergewebe verwenden. Diese Injektionsnadeln können mittels eines Schlauches aus gegenüber der Heilmittellösung indeferentem und gewerbeverträglichem Material mit einer mechanischen oder automatischen Dosiereinrichtung verbunden sein.It is known to use injection needles for the continuous or periodic subcutaneous or intramuscular introduction of an aqueous or oily medicinal solution into body tissue. These injection needles can be connected to a mechanical or automatic metering device by means of a hose made of material which is inferior to the medicinal solution and is compatible with trade.
Zur Behandlung bestimmter Krankheiten wie beispielsweise des Morbus Parkinson ist eine kontinuierliche oder periodische Zufuhr der Heilmittellösung erwünscht, da nur auf diese Weise ein gleichmäßiger Wirkstoffspiegel im Blut gewährleistet werden kann. Um dem Patienten sowohl die Bewegungsfreiheit zu erhalten, als auch eine stationäre Behandlung und Einnahmefehler zu vermeiden, verwendet man dazu üblicherweise eine elektrische Dosierpumpe, die am Körper getragen wird und die das Heilmittel über eine Schlauchleitung durch eine im subcutanen oder - Muskelgewebe fixierte Injektionskanüle abgibt. Dabei treten naturgemäß an der Eintrittsstelle im Körpergewebe höhere Heilmittelkonzentrationen als benötigt auf. Die am Injektionsort auftretende erhöhte Heilmittelkonzentration kann in Abhängigkeit von der chemischen Natur des Heilmittels sowie dessen Konzentration zu örtlichen Reizerscheinungen und entzündungsähnlichen Zuständen führen, die im Extremfall die Beendigung der Therapie erforderlich machen.For the treatment of certain diseases such as, for example, Parkinson's disease, a continuous or periodic supply of the therapeutic solution is desirable, since this is the only way to ensure a uniform active substance level in the blood. In order to maintain freedom of movement for the patient, as well as to avoid inpatient treatment and intake errors, an electric metering pump is usually used, which is worn on the body and which delivers the remedy via a hose line through an injection cannula fixed in the subcutaneous or muscle tissue. Naturally, higher concentrations of medication than required occur at the entry point in the body tissue. The increased drug concentration occurring at the injection site can be local depending on the chemical nature of the drug and its concentration Symptoms of irritation and inflammation-like conditions, which in extreme cases necessitate the termination of therapy.
In der US-PS 4 159 720 wird eine Vorrichtung beschrieben, die die Heilmittellösung aus einem auf der Haut befestigten Vorratsbehältnis durch einen im Gewebe befindlichen Docht aus Seide oder medizinischem Nahtmaterial in den Körper bringt. Diese Methode hat den Nachteil, daß die Dosierung durch die Docht -Oberf läche vorgegeben und konstant ist, somit keine dem Tagesprofil angepaßte Dosierung möglich ist. Darüber hinaus muß die Gewebeverträglichkeit des Dochtmaterials im speziellen Fall sichergestellt sein.US Pat. No. 4,159,720 describes a device which brings the medicinal solution into the body from a storage container fastened to the skin through a wick made of silk or medical suture material in the tissue. This method has the disadvantage that the dosage is predetermined and constant by the surface of the wick, so that no dosage adapted to the daily profile is possible. In addition, the tissue compatibility of the wick material must be ensured in a special case.
In der DE-OS 30 35 009 wird ein Spritzenkopf beschrieben, der mit 5 Stutzen zur Aufnahme von Injektionsnadeln versehen ist. Dieser ist jedoch als Teil einer Injektionssprltze zur Quaddelbildung vorgesehen. Bedingt durch die räumliche Ausdehnung und die konstruktiven Einzelheiten des Spritzenkopfes und der Stutzen zur Aufnahme der Injektionsspritzen ist diese Vorrichtung nicht geeignet, um nach Fixierung am gewünschten Injektionsort längere Zeit am Körper getragen zu werden. In der FR-PS 11 42 769 wird eine Injektionsnadel beschrieben, die seitliche Öffnungen aufweist, sodaß das zu injizierende Medikament im Gewebe längs der Nadel verteilt wird. Dies kann trotz der Verteilung in Tiefenwirkung zu unerwünschten Konzentrationen an der Einstichstelle führen. Von diesem Stand der Technik ausgehend liegt der Erfindung die Aufgabe zugrunde, bei einer Dauerinjektion, die zur Behandlung verschiedener Krankheiten erforderlieh ist, durch Vergrößerung der Injektionsfläche die Konzentration der Heilmittellösung am Eintrittsort bei gleichbleibender Zuflußgeschwindigkeit zu vermindern, um so die durch hohe Heilmittelkonzentration am Eintrittsort hervorgerufene Gewebe-Reizung und Entzündung zu vermeiden.In DE-OS 30 35 009 a syringe head is described which is provided with 5 nozzles for receiving injection needles. However, this is provided as part of an injection syringe for wheal formation. Due to the spatial expansion and the structural details of the syringe head and the nozzle for receiving the injection syringes, this device is not suitable for being worn on the body for a long time after being fixed at the desired injection site. FR-PS 11 42 769 describes an injection needle which has lateral openings so that the medicament to be injected is distributed in the tissue along the needle. Despite the distribution in depth, this can lead to undesirable concentrations at the injection site. Starting from this prior art, the object of the invention is to reduce the concentration of the medicinal solution at the point of entry at a constant inflow rate in the case of a continuous injection which is required for the treatment of various diseases by increasing the injection area, so as to cause the concentration of medicinal product at the point of entry to remain constant Avoid tissue irritation and inflammation.
Erfindungsgemäß wird diese Aufgabe durch die technische Lehre des Anspruchs 1 gelöst.According to the invention, this object is achieved by the technical teaching of claim 1.
Die Injektionseinrichtung ermöglicht eine vorbestimmte flächenhafte Verteilung der zu injizierenden Lösung. Die Halterung ist insbesondere so flach gestaltet, daß sie am Injektionsort gut fixierbar ist und ohne großen Raumbedarf, beispielsweise flach am Körper aufliegt. Die Injektionseinrichtung kann durch die parallelen Längsachsen der Kanülen in einfacher Weise appliziert werden.The injection device enables a predetermined areal distribution of the solution to be injected. The holder is in particular designed so flat that it can be easily fixed at the injection site and rests flat on the body, for example, without taking up much space. The injection device can be applied in a simple manner through the parallel longitudinal axes of the cannulas.
Ein besonders einfacher Aufbau wird dadurch erzielt, daß eine die starre Halterung und Speiseleitung bildende Rohrleitunganordnung vorgesehen ist, bei der die Rohrachse oder die Rohrachsen in einer Ebene liegen und mit der die Kanülen, die auf einer Seite dieser Ebene senkrecht zu dieser angeordnet sind, verbunden sind. Mit besonderem Vorteil ist die Rohrleitungsanordnung ein Rohrleitungsring. Ein derartiger Rohrleitungsring erfüllt in idealer Weise die Erfordernisse gut fixierbar zu sein und ohne großen Raumbedarf flach am Körper aufzuliegen. Ein tangentialer Anschlußstutzen ist für diesen Rohrleitungsring vorgesehen. Insbesondere sind die Kanülen im gleichen Abstand voneinander angeordnet.A particularly simple construction is achieved in that a pipeline arrangement forming the rigid holder and feed line is provided, in which the pipe axis or the pipe axes lie in one plane and with which the cannulas, which are arranged on one side of this plane perpendicular to it, are connected are. The pipeline arrangement is particularly advantageously a pipeline ring. Such a pipe ring ideally fulfills the requirements of being fixable and flat on the body without taking up much space to lie on. A tangential connection piece is provided for this pipe ring. In particular, the cannulas are arranged at the same distance from one another.
Falls neben der flächenhaften Verteilung noch eine zusätzliche Verteilung in die Tiefe erwünscht ist, sind die Kanülen mit einem geschlossenen Kanülenanschliff und mehreren seitliche Austrittsöffnungen versehen.If, in addition to the surface distribution, an additional depth distribution is desired, the cannulas are provided with a closed cannula and several side outlet openings.
Um die Applikation der erfindungsgemäßen Injektionseinrichtung durch den Patienten selbst zu erleichtern, kann in vorteilhafter Weise an der die Kanülen tragenden starren Halterung ein Griff z. B. in Bogenform angeordnet sein.In order to facilitate the application of the injection device according to the invention by the patient himself, a handle, for example, can advantageously be attached to the rigid holder carrying the cannulas. B. be arranged in an arc shape.
Ein Ausführungsbeispiel der Erfindung soll unter Bezugnahme auf die Figuren der Zeichnung beschrieben werden:An embodiment of the invention will be described with reference to the figures of the drawing:
Es zeigen:Show it:
Fig. 1 eine Draufsicht auf einen RohrleitungsringFig. 1 is a plan view of a pipe ring
Fig. 2 eine vergrößerte Ansicht des Rohrleitungsringes von untenFig. 2 is an enlarged view of the pipe ring from below
undand
Fig. 3 eine schematische, teilweise geschnittene Seitenansicht.Fig. 3 is a schematic, partially sectioned side view.
In den Figuren ist ein Rohrleitungsring 2 dargestellt. Dieser Rohrleitungsring 2 weist einen tangentialen Anschlußstutzen 1 auf, der beispielsweise mit einem Teflonschlauch in Verbindung stehen kann, an den sich ein Luer-Lookanschluß anschließt.A pipe ring 2 is shown in the figures. This pipe ring 2 has a tangential connection piece 1, which can be connected, for example, to a Teflon hose, to which a Luer look connection connects.
Wie insbesondere Fig. 3 zeigt, erstrecken sich senkrecht zur Ebene A-A des Rohrleitungsringes 2 auf einer Seite mehrere Kanülen 3, die mit diesem Rohrleitungsring in Verbindung stehen. Die Achsen der Kanülen 3 verlaufen parallel zueinander.As shown in FIG. 3 in particular, a plurality of cannulas 3 extend perpendicularly to the plane A-A of the pipe ring 2 and are connected to this pipe ring. The axes of the cannulas 3 run parallel to one another.
Eine bevorzugte Ausführungsform besteht darin, daß der zylindrische Hohlkörper ein ringförmiges Rohr mit einem Außendurchmesser von 20 mm darstellt. Der Rohrinnendurchmesser beträgt 1 mm, der Rohraußendurchmesser 1,5 mm. Senkrecht zur Ringebene sind auf derselben Seite parallel und im gleichen Abstand zueinander 4 Injektionskanülen mit einer lichten Weite von 0,2 mm und einem Außendurchmesser von 0,45 mm angebracht. Das ringförmige Rohr besitzt außerdem tangential und parallel zur Ringebene ein gerades Anschlußrohr von 16 mm Länge mit demselben Rohrquerschnitt wie das ringförmige Rohr. Durch die Anordnung der Injektionskanülen auf einem ringförmigen Rohr läßt sich diese Injektionsspritze nach dem Einstich der Kanülen am geeigneten Injektionsort durch geeignete Maßnahmen (physiologisch verträglicher Kreuz-Pflaster-Verband o.ä.) gut am Körper fixieren.A preferred embodiment is that the cylindrical hollow body is an annular tube with an outer diameter of 20 mm. The inside pipe diameter is 1 mm, the outside pipe diameter is 1.5 mm. At right angles to the ring plane, 4 injection cannulas with a clear width of 0.2 mm and an outer diameter of 0.45 mm are attached parallel and at the same distance to each other. The ring-shaped pipe also has a straight connecting pipe 16 mm long tangentially and parallel to the ring plane with the same pipe cross-section as the ring-shaped pipe. By arranging the injection cannulas on a ring-shaped tube, this injection syringe can be easily fixed to the body after the needles have been inserted at the appropriate injection site using suitable measures (physiologically compatible cross-plaster dressing or the like).
Die Handhabung der erfindungsgemäßen Injektionsnadel ist wie folgt: Das gesamte System (Dosiereinrichtung, Zuführungsschlauch und Injektionseinrichtung) wird blasenfrei mit der Hellmittellösung gefüllt und die Spritze so an der gewünschten Stelle in das Körpergewebe eingestochen, daß das ringförmige Rohr auf der Haut aufliegt. Die Injektionseinrichtung wird nun durch ein physiologisch verträgliches Pflaster o.a. am Körper befestigt und die Dosiereinrichtung in Betrieb gesetzt. The handling of the injection needle according to the invention is as follows: The entire system (dosing device, supply hose and injection device) is filled with the light medium solution without bubbles and the syringe is inserted into the body tissue at the desired location so that the ring-shaped tube lies on the skin. The injection device is now attached to the body by a physiologically compatible plaster or the like and the metering device is put into operation.
