The invention relates to a pump for the time-controlled, metered administration of medicaments, comprising a medicament reservoir, upon which pressure is exerted by means of a plunger. The pressure is regulated by scanning a profile or several profiles, which is/are incorporated into plates, discs, cylinders and/or spirals and said pressure is transmitted to the plunger by means of an adapter.

Description

Die vorliegende Erfindung betrifft eine Arzneimittelpumpe mit vorprogrammierbarer Wirkstofffreisetzung zur Langzeitverabreichung von Arzneistoffen.The present invention relates to a pharmaceutical pump Pre-programmable drug release for long-term administration of Drugs.

Arzneimittelpumpen werden vorzugsweise verwendet, um über mehrere Stunden oder Tage mit einer vorgegebenen gleichmäßigen oder variablen Abgaberate Arzneistofflösungen oder Arzneistoffemulsionen über Katheder und Kanülen parenteral (z. B. subcutan, intravenös, intraperitoneal) beim Menschen oder Tier in den Organismus einzubringen. Arzneimittelpumpen eignen sich auch für die orale, rektale und transdermale Arzneimttelverabreichung.Drug pumps are preferably used to last for several hours or days with a given uniform or variable delivery rate Drug solutions or drug emulsions over catheters and cannulas parenterally (e.g. subcutaneously, intravenously, intraperitoneally) in humans or animals to bring into the organism. Drug pumps are also suitable for the oral, rectal and transdermal drug delivery.

Zur parenteralen Applikation von Arzneistoffen werden implantierbare Infusionspumpen (EP 00513299 B1) und extern tragbare Pumpen (EP 00168472 B1) beschrieben. Pumpen können mit Injektionsspritzen kombiniert werden, aus denen das Arzneimittel durch Vorschub des Spritzenkolbens freigesetzt wird (EP 00142736 B). Eine Steuerung der Freisetzung über eine Gewindestange wird in EP 0916353 beschrieben.Implantable drugs are used for parenteral application of drugs Infusion pumps (EP 00513299 B1) and externally portable pumps (EP 00168472 B1). Pumps can be combined with hypodermic syringes be made up of the drug by advancing the syringe plunger is released (EP 00142736 B). A control of the release via a Threaded rod is described in EP 0916353.

Zur Abgabe des Arzneistoffs aus Pumpen werden unterschiedliche Prinzipien verwendet. In U.S. Pat. 4,386,929 und U.S. Pat. 4,265,241 werden unter Druck stehende ballonartige Arzneistoffreservoirs beschrieben, die sich langsam entleeren. Im Weiteren werden in U.S. Pat. 5,100,389 und U.S. Patent 4,744,786 federdruck- und gasdruckbetriebene Spritzenpumpen beschrieben. Bei Pumpen, die mit einer variablen Freisetzungsrate den Arzneistoff abgeben, dienen meist elektronische Steuerungen zur Regelung der Freisetzung. Elektronische Steuerungen sind für Patienten meist schwer zu bedienen. Fehler können dabei auftreten. Wird bei Spritzenpumpen der Kolbenvorschub durch Schrittmotoren bewirkt, können Ungenauigkeiten in der Wirkstoffdosierung auftreten.There are different principles for dispensing the drug from pumps used. In U.S. Pat. 4,386,929 and U.S. Pat. 4,265,241 are under pressure standing balloon-like drug reservoirs described that slowly Drain. Furthermore, in U.S. Pat. 5,100,389 and U.S. Patent 4,744,786 described spring pressure and gas pressure operated syringe pumps. For pumps, which release the drug with a variable release rate usually serve electronic controls for regulating the release. electronic Controls are usually difficult to operate for patients. Mistakes can occur occur. In the case of syringe pumps, the piston is fed by stepper motors causes inaccuracies in the drug dosage.

Dieser Nachteil wird durch die vorliegende Erfindung behoben. Es handelt sich wie bei anderen Pumpen zur Verabreichung von Arzneistofflösungen bei der vorliegenden Erfindung vorzugsweise um eine Pumpe, bei der ein spritzenartiges Arzneistoffreservoir z. B. über einen Kolben entleert wird. Der Arzneistoff wird vorzugsweise als Lösung über mehrere Stunden abgegeben. Erfindungsgemäß wird die zeitlich gesteuerte Bewegung des Kolbens mit Hilfe von Profilen erreicht, die als sogenannte Nocken auf Platten, Scheiben, Zylindern oder Spiralen eingefräst oder eingeprägt sind. Wird z. B. ein Abtasters gleichmäßig über mehrere Stunden entlang dieses Nockenprofils geführt, so wird jeweils nur soviel Arzneistofflösung aus dem Reservoir freigegeben, wie durch das Nockenprofil vorgegeben ist.This disadvantage is overcome by the present invention. It is about as with other pumps for the administration of drug solutions in the present invention preferably around a pump in which a syringe-like Drug reservoir z. B. is emptied via a piston. The drug will preferably given as a solution over several hours. According to the invention is the time-controlled movement of the piston using profiles reached, the so-called cams on plates, disks, cylinders or Spirals are milled or stamped. Is z. B. a scanner evenly over several hours along this cam profile, so only released as much drug solution from the reservoir as by the Cam profile is specified.

Beispiel 1example 1

In Abb. 1 ist ein Beispiel für eine erfindungsgemäße Ausführung der Arzneimittelpumpe wiedergegeben. Der zeitliche Verlauf der Freisetzung des Arzneimittels (Insulin-Lösung) aus dem Arzneistoffreservoir (Spritze) ist als Wellenprofil auf der Programmkarte A eingefräst. Der Abtaster D wird auf einer Gewindestange gleichmäßig über 24 Stunden in Pfeilrichtung bewegt. Dadurch wird die unter Federdruck (Pfeilrichtung C) stehende Programmkarte mit der mit ihr verbundenen Kolbenstange, die den Kolben im Arzneistoffreservoir bewegt, jeweils nur in dem Ausmaß vorwärtsbewegt, wie durch das auf der Programmkarte A eingefräste Profil möglich ist. Fig. 1 shows an example of an embodiment of the pharmaceutical pump according to the invention. The time course of the release of the drug (insulin solution) from the drug reservoir (syringe) is milled on the program card A as a wave profile. The scanner D is moved on a threaded rod evenly over 24 hours in the direction of the arrow. As a result, the program card, which is under spring pressure (arrow direction C), with the piston rod connected to it, which moves the piston in the drug reservoir, is only moved forward to the extent that is possible by the profile milled on program card A.

Die Ergebnisse von Freigabeuntersuchungen zeigen, dass die Arzneistoffdosierung variabel über einen Zeitraum von 24 Stunden gesteuert werden kann.The results of release studies show that the Drug dosing variably controlled over a period of 24 hours can be.

Beispiel 2Example 2

In Abb. 2 ist ein Beispiel für eine erfindungsgemäße Ausführung der Arzneimittelpumpe wiedergegeben. Die Arzneimttelpumpe besitzt die Form eines sogenannten Insulin-Pens. Ein Insulin-Pen ist eine Injektionsspritze mit einstellbarer Dosierung. Der zeitliche Verlauf der Pumprate der Arzneimittelpumpe ist über ein Profil vorgegeben, das in den Zylinder A eingefräst ist. Durch den Motor C wird der Abtaster D gleichmäßig mit einer Umdrehung innerhalb von 48 Stunden entlang des Profils geführt. Der Kolbenvorschub und damit die Freisetzung aus dem Arzneistoffreservoir ist abhängig von dem Verlauf des Profils. Fig. 2 shows an example of an embodiment of the pharmaceutical pump according to the invention. The drug pump is in the form of a so-called insulin pen. An insulin pen is a syringe with adjustable dosage. The time course of the pumping rate of the drug pump is specified via a profile which is milled into cylinder A. The motor D guides the scanner D uniformly along the profile with one revolution within 48 hours. The piston advance and thus the release from the drug reservoir depends on the profile.

Beispiel 3Example 3

In Abb. 3 ist für eine Insulinpumpe ein über 24 Stunden vorgesehenes Insulinprofil (Abb. 3a und b) und dessen Übertragung auf eine Programmkarte (Abb. 3c) dargestellt. Das in die Programmkarte eingefräste Profil entspricht der gewünschten kumulativen Insulinabgabe. Bei einer gleichmäßigen Bewegung des Abtasters in Pfeilrichtung während der vorgesehene Zeitdauer der Freisetzung wird aus der Spritze über ein Katheder die Insulin-Injektion vorgenommen. Fig. 3 shows an insulin profile for 24 hours for an insulin pump ( Fig. 3a and b) and its transfer to a program card ( Fig. 3c). The profile milled into the program card corresponds to the desired cumulative insulin delivery. If the scanner moves evenly in the direction of the arrow during the intended duration of the release, the syringe is injected via a catheter.

Beispiel 4Example 4

In Abb. 4 sind zwei unterschiedliche Profile zur Steuerung der Arzneistofffreigabe aus den erfindungsgemäßen Pumpen dargestellt. Durch die unterschiedlichen Verläufe wird das Ausmaß der Freisetzung (5,6 mm bzw. 12,9 mm Gesamtkolbenvorschub) und der Verlauf der Wirkstoffabgabe vorgegeben. Fig. 4 shows two different profiles for controlling drug release from the pumps according to the invention. The extent of the release (5.6 mm or 12.9 mm total piston advance) and the course of the drug delivery are predetermined by the different courses.

Beispiel 5Example 5

In Abb. 5 ist das Ergebnis einer Freisetzungsuntersuchung von Insulin aus einer erfindungsgemäßen, mit Programmkarten gesteuerten Insulinpumpe wiedergegeben. Das vorgegebene Profil (geschlossenen Kreise) entspricht dem in Abb. 3 dargestellten Profil. Das Ergebnis der Anwendungsuntersuchung in Abb. 5 (offene Kreise) zeigt, dass die vorgesehene Freisetzung mit hoher Genauigkeit durch die Pumpe eingehalten werden kann. Fig. 5 shows the result of a release study of insulin from an insulin pump according to the invention, controlled by program cards. The given profile (closed circles) corresponds to the profile shown in Fig. 3. The result of the application investigation in Fig. 5 (open circles) shows that the intended release can be maintained with high accuracy by the pump.
