Abstract
Description
Die Erfindung betrifft eine statische Ballonpumpe zur mobilen Langzeit-Infusion ohne Fremdenergie.The The invention relates to a static balloon pump for mobile long-term infusion without external energy.
Stand der TechnikState of technology
Aus medizinischer Sicht ist für Patienten die kontinuierliche Verabreichung von Medikamenten (z.B. Krebsbehandlung, Schmerztherapie) weitaus vorteilhafter als die intermittierende Infusion.Out medical view is for Patients continue to receive medication (e.g. Cancer treatment, pain therapy) far more beneficial than the intermittent infusion.
Die Verabreichung von Arzneimitteln zur Behandlung oder Nachsorge Schwerkranker über intravasale Katheter mit Spritzenpumpen ist wegen des technischen Aufwandes immer mit stationärem Aufenthalt der Patienten in der Klinik verbunden, was die Lebensqualität der Patienten wegen der fehlenden Mobilität entscheidend beeinträchtigt.The Administration of medicines for the treatment or aftercare of the seriously ill via intravascular Catheter with syringe pumps is because of the technical effort always with stationary Stay of the patients connected in the clinic, which improves the quality of life of patients because of the lack of mobility decisively impaired.
Im Interesse der Patienten und aus Kostengründen wurden deshalb Infusionssysteme entwickelt, die den Patienten die Bewegungsfreiheit weiterhin gewährleisten und damit das Vorhandensein ihrer Erkrankung wenigstens zeitweise vergessen lassen.in the Patients' interest and cost reasons therefore became infusion systems designed to continue to provide the patient with freedom of movement and thus the existence of their disease, at least temporarily forget it.
Diese Lösungen basieren auf Systemen, in welchen das Medikament gespeichert ist und in einem Vorratsbehältnis am Körper getragen werden kann. Die Abgabe erfolgt durch Überdruck im Vorratsbehältnis, die Dosierung über mechanische Flußregelelemente.These solutions are based on systems in which the drug is stored and in a storage container on the body can be worn. The delivery is made by overpressure in the storage container, the Dosage over mechanical flow control elements.
Der Überdruck im Medikamentenbehältnis wird erzeugt durch elastische Vorspannung eines Kontruktionselementes, z.B. des Vorratsballons selbst oder Feder-/Gewichtskraft, die über die als Membran wirkende Wand des Vorratsbehältnisses wirkt.The overpressure in the medicine container produced by elastic prestressing of a constructional element, e.g. of the reserve balloon itself or spring / weight force over the acting as a membrane wall of the storage container acts.
Elektrisch betriebene Spritzenpumpen binden die Patienten stationär. Tragbare Pumpen (vorzugsweise benutzt in der Diabetestherapie) sind teuer und fordern eine genaue Schulung der Patienten im Gebrauch. Um den Patienten den Komfort der Bewegungsfreiheit zu erhalten, benötigen die Pumpen für ihre Funktion elektrische Energie aus Batterien.electrical operated syringe pumps bind patients inpatient. portable Pumps (preferably used in diabetes therapy) are expensive and demand accurate training of patients in use. To the Patients need the comfort of freedom of movement that they need Pumps for their function is electrical energy from batteries.
Für ungeübte oder in den Aktionen beeinträchtigte Patienten (Schmerzbehandlung, Krebstherapie) sind zur kontinuierlichen Infusion Systeme am Markt, die ortsunabhängig und ohne besonderen Aufwand in der Bereitstellung der Medikamentation anwendbar sind. Für diese Patientengruppen wurden Infusionssysteme entwickelt, die ohne elektrische Energie und mit vorbereiteten Medikamentenreservoirs auch ohne ärztliche Hilfe an Gefäßzugänge angeschlossen werden können und mit hoher Sicherheit die vorgegebene Medikationsmenge über die vorgesehene Infusionszeit abgeben.For inexperienced or affected in the actions Patients (pain treatment, cancer therapy) are for continuous Infusion systems on the market, independent of location and without any special effort are applicable in the provision of the medication. For this Patient groups have developed infusion systems that are without electrical energy and with prepared drug reservoirs even without medical Help connected to vascular access can be and with high certainty the prescribed amount of medication on the intended Deliver infusion time.
Das zentrale Problem dieser Infusionssysteme ist die Aufrechterhaltung einer konstanten Flußrate über die gesamte Entleerungszeit.The central problem of these infusion systems is the maintenance a constant flow rate over the total emptying time.
Wesentlichen Einfluß hierauf hat die Erzeugung eines möglichst konstanten Überdruckes im Vorratsbehältnis.essentially Influence on this has the generation of one possible constant overpressure in the storage container.
Die am Markt befindlichen Ballonsysteme arbeiten in der Dosierkonstanz und -kontinuität im Routinebetrieb zwar zufriedenstellend, haben aber doch Defizite in Details, wie
- • erhöhte Dosis beim Anlaufen,
- • verringerte Dosis ab 80% Entleerung,
- • starke Abhängigkeit von der Viskosität des Arzneimittels,
- • Temperaturdrift,
- • Abhängigkeit vom Gefäßzugang,
- • zwischenzeitlicher Stillstand wegen Luftblasen im Flußbegrenzer,
- • teilweise große Restmengen im Infusor.
- • increased dose at startup,
- • reduced dose from 80% emptying,
- Strong dependence on the viscosity of the drug,
- Temperature drift,
- • dependence on vascular access,
- • interim stoppage due to air bubbles in the flow restrictor,
- • some large residues in the infuser.
Der Erfindung liegt die Aufgabe zugrunde, ein Infusionssystem bereitzustellen, welches am Körper getragen werden kann und ohne Fremdenergie langzeitig (über mehrere Stunden oder Tage) eine medikamentöse Flüssigkeit über Katheter in den Körper eines Patienten infundiert.Of the Invention has for its object to provide an infusion system, which on the body can be worn and without external energy long term (over several Hours or days) of a medicinal fluid via catheter into the body of a Patient infused.
Zum Erzeugen weitgehendst konstanter Dosierraten aufgrund der elastischenTo create largely constant metering rates due to the elastic
Kontraktionskraft des Vorratsballons wurde bisher das Material Latex verwendet. Aufgrund des neuerlichen Verbotes der Verwendung von Latex-Material wegen seiner allergenen Eigenschaften sind neue Lösungen gefragt, mit welchen eine ausreichende Druckkonstanz des Ballons beim Entleeren und in Verbindung mit dem Flußbegrenzer eine akzeptable Abgabekonstanz für das Medikament erreicht wird.contractile force the supply balloon was previously used the material latex. by virtue of the recent ban on the use of latex material its allergenic properties require new solutions with which a sufficient pressure constancy of the balloon during emptying and in Connection to the flow limiter an acceptable output constancy for the drug is achieved.
Lösungsolution
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mit einem teleskopartigen Aufbau des Grundkörpers für eine statische Ballonpumpe die zuvor beschriebenen Nachteile weitgehendst ausgeschlossen werden.These Task is inventively characterized solved, that with a telescopic structure of the body for a static balloon pump the disadvantages described above are largely excluded.
