Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung, mit dessen Hilfe Arzneistoffe, vorzugsweise in pastöser oder flüssiger Form, evtl. unter Zuhilfenahme von penetrations­ vermittlern, wie beispielsweise DMSO, mengen- und zeitmäßig gezielt in das Untergewebe der Haut eingebracht werden kann.The invention relates to a method and a device, with the help of drugs, preferably in pasty or liquid form, possibly with the help of penetrations intermediaries, such as DMSO, in terms of quantity and timing can be specifically introduced into the lower tissue of the skin can.

Auch ist eine implantierfähige Form einer Kapsel denkbar, oder die elektronisch steuerbare Wirkstoffkapsel kann als Depotsystem z. B. im Rachenraum "verankert" werden, um dort, in abstimmbaren Intervallen einen geeigneten Wirkstoff abzugeben.An implantable form of a capsule is also conceivable or the electronically controllable active ingredient capsule as a deposit system z. B. "anchored" in the pharynx, to find a suitable one there at adjustable intervals Deliver active ingredient.

Besonders vorteilhaft ist jedoch diese Vorrichtung, wenn sie als steuerbare Wirkstoffkapsel, im Bereich der trans­ dermalen Systeme (subkutan wirkende Pflaster mit Wirk­ stoffen), eingesetzt wird. However, this device is particularly advantageous if it as a controllable active ingredient capsule, in the field of trans dermal systems (subcutaneously acting plasters with active substances) is used.  

Der Vorteil dieser neuen Präparateform besteht auch darin, daß, besonders bei älteren, wohlmöglich vergeßlichen Patienten, die Wirkstoffabgabe vom Arzt oder von der programmierbaren (oder fest programmierten) Wirkstoffkap­ sel her festgelegt werden kann. Auch kann eine Ansteuer­ einheit (Uhrenbaustein) die Abgabe von Wirkstoff z. B. während einer Ruhephase (Nacht) reduzieren oder gänzlich abstellen.The advantage of this new form of preparation is also that that, especially with older ones, is probably forgetful Patients receiving drug delivery from the doctor or from the programmable (or permanently programmed) active ingredient cap sel her can be determined here. Can also be a control unit (clock module) the delivery of active ingredient z. B. reduce during a rest period (night) or completely Off.

Das war mit den bisherigen transdermalen Systemen nicht möglich.That was not the case with the previous transdermal systems possible.

Die Erfindung betrifft eine den Wirkstoff enthaltende De­ potkammer, die wiederum mit einer elektrochemischen Zelle, (wie sie z. Bs. von der Firma Simatec AG, CH 3360 Herzogen­ buchsee hergestellt wird) verbunden ist, die beim Kurz­ schließen der beiden Pole Wasserstoffgas (oder auch Sauer­ stoff) bildet. Damit wird nun, vorzugsweise durch eine geeignete Folie getrennt, Druck auf die Wirkstoffblase (hier als Depotkammer bezeichnet) ausgeübt. Über eine kommunizierende Kanäle oder eine kapillarisch/transparente Folie, die mit der üblichen Heftpflastertechnik auf der Haut, an geeigneter Stelle angebracht, wird nun der Wirk­ stoff zeitlich- und mengenmäßig gezielt abgegeben.The invention relates to a De containing the active ingredient pot chamber, which in turn has an electrochemical cell, (as e.g. from Simatec AG, CH 3360 Herzogen buchsee) is connected, which is short close the two poles of hydrogen gas (or acid fabric) forms. So now, preferably by a suitable film separated, pressure on the active ingredient bladder (here referred to as the depot chamber). Over a communicating channels or a capillary / transparent Foil made with the usual adhesive plaster technique on the Skin, placed in a suitable place, now becomes active Targeted release of material in terms of time and quantity.

Die Gasproduktion ist praktisch äquivalent zum Strom, d. h., die Gasmenge pro Zeiteinheit kann über einen Außen­ widerstand fixer oder verstellbarer Art bestimmt werden. Die Gaszellen arbeiten ohne leglichen Fremdstrom. Die Abmessungen einer Gasentwicklungszelle betragen etwa 7.8×3.5 mm. Die Kapazität liegt, je nach Typ, bei ca. 25-150 ml H2-Gas.Gas production is practically equivalent to electricity, ie the amount of gas per unit of time can be determined via an external resistance of a fixed or adjustable type. The gas cells work without legal external electricity. The dimensions of a gas development cell are approximately 7.8 × 3.5 mm. Depending on the type, the capacity is approx. 25-150 ml H 2 gas.

Die Erfindung sieht nun eine feste Verbindung mit einem, per SMD-Technik gebauten Mikrochip vor. Wobei die kom­ plette Einheit: (für den Antrieb) die Gasentwicklungs­ zelle, eine Depotkammer (die den Wirkstoff enthält), das Übertragungselement (eine durchlässige Folie oder ein Kanülensystem), sowie der ob. erwähnte Steuerchip, die Wirkstoffkapsel bilden.The invention now sees a fixed connection with a Microchip built using SMD technology. Whereby the com Plette unit: (for the drive) the gas development cell, a depot chamber (containing the active ingredient) that Transmission element (a permeable film or a Cannula system), as well as the above-mentioned control chip, the Form active ingredient capsule.

Es ist auch eine Plazierung dieser Wirkstoffkapsel im Rectum oder im vaginalen Bereich denkbar.It is also a placement of this drug capsule in the rectum or conceivable in the vaginal area.

Es ist auch eine Ausführung denkbar, bei der der Wirkstoff, bzw. die Gaserzeugung als Treibmedium, über einen (Glu­ cose-) Sensor gesteuert wird, um z. Bs. bei Diabetes­ patienten die Insulinabgabe zu regeln. Diese neuen transdermale Systeme könnten ein zusätzliches akus­ tisches (Pfeifton) Signal abgeben, damit der Patient den Zeitpunkt der Wirkstoffabgabe kontrollieren kann. Als Funktionsprüfung wie auch zur Eigenüberwachung seines Befindens (vorher/nachher).An embodiment is also conceivable in which the active ingredient, or gas generation as a propellant, via a (Glu cose-) sensor is controlled to z. For diabetes regulate insulin delivery. These new ones transdermal systems could be an additional acus table (whistle) signal so that the patient the Can control the time of drug delivery. As Functional test as well as self-monitoring of his Condition (before / after).
