Description
Die vorliegende Erfindung bezieht sich auf Kapseln zur Aufnahme eines Volumens von Strömungsmittel unter hohem Druck, d.h. zwischen 30 und 80 bar.The The present invention relates to capsules for containing a Volume of fluid under high pressure, i. between 30 and 80 bar.
Verschlossene Kapseln sind in Fällen gut bekannt, wo die Kraft des Strömungsmittels unter Druck zum Abgeben einer Substanz wie beispielsweise Abgeben von Fassbier aus einem Bierzapfhahn oder zum Austreiben von Sodawasser aus einem Sodasiphon angewendet wird. Sie können auch für Flüssigkeitsbehälter für Softgetränke oder Bier unter Druck benutzt werden.locked Capsules are in cases Well known where the force of the fluid under pressure for Dispensing a substance such as dispensing draft beer a beer tap or for expelling soda from a Soda siphon is applied. You can also use for liquid containers for soft drinks or Beer be used under pressure.
Es ist auch bekannt, verschlossene Kapseln, die Helium unter hohem Druck enthalten, in medizinischen Geräten zu verwenden, um die Energie des druckbeaufschlagten Heliums zum Austreiben eines therapeutischen Agens durch die Haut eines Patienten auszunutzen. In der veröffentlichten PCT-Anmeldung WO 94/24 263 ist eine nadellose Spritze beschrieben, die eine Metallkapsel aufweist, die Heliumgas unter hohem Druck enthält, das zum Austreiben von Teilchen eines therapeutischen Agens durch die Haut eines Patienten in im wesentlichem schmerzfreier Weise benutzt wird. Die Kapsel ist von der restlichen Spritze lösbar, und nach Gebrauch kann entweder eine neue Gasladung in die Kapsel eingebracht werden oder in besserer Weise kann die Kapsel weggeworfen und eine neue mit Gas beladene Kapsel an der übrigen Spritze befestigt werden.It is also known closed capsules containing helium under high Pressure included in medical devices to use the energy of pressurized helium for expelling a therapeutic To exploit agent through the skin of a patient. In the published PCT Application WO 94/24263 describes a needleless syringe, which has a metal capsule, the helium gas under high pressure contains that for expelling particles of a therapeutic agent through the Used a patient's skin in a substantially pain-free manner becomes. The capsule is detachable from the remaining syringe, and after use, either a new gas charge can be introduced into the capsule or better, the capsule can be thrown away and one new gas-loaded capsule to be attached to the remaining syringe.
Die EP-0 821 195 beschreibt eine Gaskapsel zur Speicherung von Helium unter Druck.The EP-0 821 195 describes a gas capsule for storing helium vacuum.
In dem Fall, wo die Gaskapsel ein Wegwerfartikel ist, ist es wichtig, dass sie einfach und billig hergestellt werden kann. Bei medizinischen Anwendungen ist Heliumgas ein favorisiertes Strömungsmittel, da es sehr leicht ist, was es zur Verwendung als Treibmittel für therapeutische Agenzien macht, weil, wenn es auf die Haut eines Patienten auftrifft, es in die Atmosphäre abprallt und nicht durch die Haut des Patienten hindurchgelangt. Jedoch ist Helium, weil es leicht ist, schwierig zu halten, da es durch die kleinsten Fehler in einem Behälter hindurchleckt.In In the case where the gas capsule is a disposable item, it is important that it can be produced easily and cheaply. In medical Applications, helium gas is a favorite fluid, as it is very light is what makes it useful as a propellant for therapeutic agents because, when it hits the skin of a patient, it bounces off into the atmosphere and not through the skin of the patient. However, that is Helium, because it is easy to keep difficult as it is by the smallest Error in a container through leaking.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Füllen einer Kapsel mit Strömungsmittel unter hohem Druck zu schaffen, und insbesondere ein Verfahren zum Füllen einer Gaskapsel mit Helium unter einem Druck von mindestens 30 bar.Of the The present invention is based on the object, a method to fill a capsule with fluid under high pressure, and in particular a method for To fill a gas capsule with helium under a pressure of at least 30 bar.
Gemäß der vorliegenden Erfindung weist ein Verfahren zum Füllen einer Kapsel mit einem hohlen Körperteil und einem davon wegragenden hohlen Halsteil mit einem Strömungsmittel unter Druck die Schritte auf:
- a) strömungsdichtes Anbringen einer Füllkappe am freien Ende des Halsteils anfänglich zum Evakuieren des hohlen Körperteils und anschließend zum Füllen des hohlen Körperteils mit dem Strömungsmittel unter Druck,
- b) bei noch an Ort und Stelle befindlicher Füllkappe und noch auf das Strömungsmittel ausgeübtem Druck crimpen des Halsteils an einer vom freien Ende des Halsteils beabstandeten Stelle,
- c) Abnehmen der Füllkappe und dadurch Freigeben des freien Endes des Halsteils,
- d) Anbringen einer zweiten Crimpung an oder unmittelbar angrenzend an das freie Ende des Halsteils, und
- e) Verschweißen des freien Endes des Halsteils zum hermetischen Abdichten der Kapsel.
- a) fluidly attaching a filler cap at the free end of the neck portion initially to evacuate the hollow body portion and then to fill the hollow body portion with the fluid under pressure,
- b) with the filling cap still in place and still exerting pressure on the fluid, crimp the neck portion at a location spaced from the free end of the neck portion;
- c) removing the filling cap and thereby releasing the free end of the neck portion,
- d) attaching a second crimp at or immediately adjacent to the free end of the neck portion, and
- e) welding the free end of the neck to hermetically sealing the capsule.
Vorzugsweise ist das Strömungsmittel Helium unter einem Druck von mindestens 30 bar.Preferably is the fluid Helium under a pressure of at least 30 bar.
Eine Ausführungsform der Erfindung wird nunmehr beispielshalber beschrieben, wobei Bezug auf die Figuren der anliegenden schematischen Zeichnung genommen wird, in denen:A embodiment The invention will now be described by way of example, with reference to the figures of the attached schematic drawing is taken, in which:
Wie
dargestellt, steht eine Kapsel
Wenn
die Kapsel
Die
Füllkappe
wird dann vom freien Ende
Der
Zweck der ersten Crimpung ist, zu verhindern, dass Strömungsmittel
unter Druck die zweite Crimpung und so das freie Ende
Die Crimpungen können weder mit einem kreisförmigen schmiedeartigen Quetschwerkzeug oder einem einfachen flachen Quetschwerkzeug bewirkt werden.The Crimping can neither with a circular forged crimping tool or a simple flat crimping tool be effected.
Wenn die Kapsel in Verbindung mit einer nadellosen Spritze benutzt werden soll, ist das Strömungsmittel Helium unter einem Druck von mindestens 30 bar.If the capsule can be used in conjunction with a needleless syringe shall, is the fluid Helium under a pressure of at least 30 bar.
Natürlich gibt es weitere Anwendungen, wo die Kapsel ein Gas oder eine Flüssigkeit unter einem Druck von wesentlich weniger als 30 bar enthält.Of course there There are other applications where the capsule is a gas or a liquid under a pressure of substantially less than 30 bar.
