Abstract

It is described a method of filing a capsule with the fluid under pressure, mainly with fluid helium to putting the syringe without the grouting point for painless application for patient.

Description

Oblasť technikyTechnical field

Vynález sa týka bombičiek, obsahujúcich objem kvapaliny pod vysokým tlakom, najmä medzi 30.106 až 80.106 Pa.The invention relates to cylinders containing a volume of liquid under high pressure, in particular between 30.10 6 and 80.10 6 Pa.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Zatavenie zatvorenej bombičky je známe v prípadoch, kedy sa využíva tlak kvapaliny na vypudenie inej látky, ako je tomu pri vyprázdňovaní zásobníka piva alebo pri získavaní sódovky zo sifónovej fľaše. Bombičky sa môžu tiež využiť v prípade zásobníka kvapalín, ako je tomu v prípade nápojov a piva, skladovaných pod tlakom.Sealing of the closed cartridge is known in cases where liquid pressure is used to expel another substance, such as emptying the beer container or recovering soda from a siphon bottle. The cartridges can also be used in the case of a liquid reservoir, as is the case with beverages and beer stored under pressure.

Je tiež známe použitie zatavených bombičiek, obsahujúcich hélium pod vysokým tlakom, v lekárskych prístrojoch, kedy sa využíva energia stlačeného lítia na pretlačenie terapeutického činidla kožou pacienta.It is also known to use sealed capsules containing helium under high pressure in medical devices using compressed lithium energy to push the therapeutic agent through the skin of a patient.

Vo zverejnenej PCT prihláške WO94/24 263 sa opisuje injekčná striekačka bez ihly, spojená s kovovou bombičkou s obsahom hélia pod vysokým tlakom. Tá sa používa na pretlačenie čiastočiek terapeutického činidla kožou pacienta bez bolestivého pocitu. Bombičku je možné oddeliť od zvyšnej injekčnej striekačky a po jej použití sa môže naplniť novou dávkou plynu alebo sa takáto bombička môže zahodiť a na striekačku sa napojí nová bombička.PCT Publication No. WO94 / 24 263 discloses a needle-free syringe coupled to a high pressure helium metal cartridge. This is used to push the therapeutic agent particles through the skin of the patient without a painful feeling. The cartridge can be detached from the remaining syringe and, after use, can be filled with a new dose of gas or the cartridge can be discarded and a new cartridge attached to the syringe.

V prípadoch, keď sa bombička zahodí, je dôležité, aby sa dala vyrobiť jednoduchšie a lacnejšie. Pri lekárskych aplikáciách je výhodným tlakovým pohonom plynové hélium, pretože je veľmi ľahké, vhodné ako pohonné činidlo terapeutických látok, pretože po náraze na kožu pacienta unikne do atmosféry okolo a neprenikne kožou pacienta. Ale pretože je hélium veľmi ľahké, ťažko sa v zásobníčku alebo bombičke udrží, unikne totiž aj najmenšou štrbinkou.In cases where the cartridge is discarded, it is important that it can be made easier and cheaper. In medical applications, helium gas is the preferred pressure propulsion, since it is very light, suitable as a propellant for therapeutic agents, since it will escape into the atmosphere around the patient's skin and do not penetrate the patient's skin. But because helium is very light, it is difficult to hold in the reservoir or cartridge, because it escapes even the smallest crevice.

Dokument EP0757202 opisuje systém na dodávanie plynu a kapsulu, kde kapsula obsahuje telovú časť obsahujúcu plyn s vysokým tlakom. Telová časť je utesnená zarážkovým členom, ktorý je umiestnený v hrdle telovej časti. Zarážka je privarená laserom k hrdlu telovej časti.EP0757202 discloses a gas supply system and a capsule, wherein the capsule comprises a body portion containing a high pressure gas. The body portion is sealed by a stop member located in the neck of the body portion. The stop is laser welded to the neck of the body part.

Dokument EP0821195 opisuje alternatívne usporiadanie kapsuly. Kapsula obsahuje telovú časť spojenú buď so zarážkovým členom ako v uvedenej prihláške, alebo viečkom majúcim dutý driek. Zarážkový člen alebo viečkový člen je typicky privarený laserom k hrdlu telovej časti. V dokumente nie je žiadny opis, ktorý by sa týkal toho, ako môže byť dutý driek utesnený.EP0821195 describes an alternative capsule arrangement. The capsule comprises a body portion connected either to the stop member as in said application or to a cap having a hollow stem. The stop member or cap member is typically laser welded to the neck of the body portion. There is no description in the document as to how the hollow shaft can be sealed.

Je preto zmyslom a úlohou tohto vynálezu nájsť spôsob plnenia bombičky kvapalinou pri vysokom tlaku, predovšetkým potom spôsob plnenia plynovej bombičky héliom pod tlakom najmenej 30.106 Pa.It is, therefore, an object and object of the present invention to provide a method of filling a cartridge with a high pressure liquid, in particular a method of filling a gas cartridge with helium at a pressure of at least 30.10 6 Pa.

Prehľad obrázkov na výkresochBRIEF DESCRIPTION OF THE DRAWINGS

Uskutočnenie podľa tohto vynálezu bude teraz opísané cestou príkladu s odkazom na pripojené vyobrazenia , ktoré sú na pripojených obrázkoch, kde na obr. 1 je prierezový pohľad na bombičku, obsahujúcu kvapalinu pod tlakom, na obr. 2 je podobný prierez, ako na obr. 1, ale obsahujúci prvé zúženie na krčkovej časti bombičky, a obr. 3 sa podobá obr. 1 a 2, ale obsahuje druhé zúženie na krčkovej časti podľa tohto vynálezu.An embodiment of the present invention will now be described by way of example with reference to the accompanying drawings, which are in the accompanying drawings, in which: FIG. 1 is a cross-sectional view of a cartridge containing a pressurized liquid, FIG. 2 is a cross-section similar to FIG. 1, but including a first constriction on the neck portion of the cartridge, and FIG. 3 is similar to FIG. 1 and 2, but includes a second neck portion in accordance with the present invention.

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION

Ako je zrejmé, bombičkou 1 je duté valcovité teleso 2, napríklad z hliníka alebo zliatiny hliníka, z ktorého vyčnieva predĺžená krčková časť 4 menšieho priemeru v porovnaní s časťou 2. Krčková časť 4 má zo začiatku otvorený voľný koniec 6.As can be seen, the cartridge 1 is a hollow cylindrical body 2, for example of aluminum or an aluminum alloy, from which the extended neck portion 4 of a smaller diameter protrudes from the portion 2. The neck portion 4 initially has an open end 6.

Ak je želané naplniť bombičku 1 kvapalinou, akou je skvapalnené hélium pod tlakom, pripojí sa nezakreslený plniaci uzáver spôsobom, ktorý je sám osebe známy, na voľný koniec 6 krčkovej časti 4. Plniaci uzáver sa najskôr spoji s vákuom, aby sa evakuovala dutá valcovitá časť 2, pričom sa táto časť 2 naplní kvapalinou pod tlakom. Zatiaľ čo je plniaci uzáver stále na mieste na voľnom konci krčkovej časti 4 a tlak sa stále vyvodzuje na kvapalinu v dutej časti 2, krčková časť 4 sa zúži v mieste, vzdialenom od uvedeného voľného konca 6 (pozri obr. 2). Toto zúženie sa uskutoční dostatočne pevne, aby sa predišlo akémukoľvek podstatnejšiemu úniku kvapaliny z dutej časti, to znamená z dutej valcovitej časti 2.If it is desired to fill the cartridge 1 with a liquid such as liquefied helium under pressure, a non-drawn filler cap is attached in a manner known per se to the free end 6 of the neck portion 4. The filler cap is first coupled to vacuum to evacuate the hollow cylindrical portion 2, wherein this part 2 is filled with a liquid under pressure. While the filler cap is still in place at the free end of the neck portion 4 and the pressure is still applied to the liquid in the hollow portion 2, the neck portion 4 narrows at a location remote from said free end 6 (see FIG. 2). This constriction is made strong enough to prevent any substantial leakage of liquid from the hollow part, i.e. the hollow cylindrical part 2.

Plniaci uzáver sa ďalej odstráni z voľného konca krčkovej časti 4, takže sa tým odkryje uvedený voľný koniec 6. Bezprostredne potom, čo sa odkryje voľný koniec 6, sa uskutoční druhé zúženie (pozri obr. 3) v mieste voľného konca alebo v bezprostrednom susedstve a v podstate v rovnakom čase sa laserovo uzavrie voľný koniec 6, takže sa tým hermeticky zataví voľný koniec krčkovej časti 4.The filler cap is further removed from the free end of the neck portion 4, thereby exposing said free end 6. Immediately after the free end 6 is uncovered, a second constriction (see Fig. 3) is performed at the free end location or in the immediate vicinity and at substantially the same time, the free end 6 is laser closed so that the free end of the neck portion 4 is hermetically sealed.

Cieľom prvého zúženia je predísť tomu, aby sa kvapalina pod tlakom dostala k druhému zúženiu a preto aj k voľnému koncu 6, takže laserové uzavretie je možné uskutočniť bez vzniku dierok s plynovou permeabilitou. Skutočne obidve zúženia definujú vnútorný priestor, ktorý predchádza alebo inhibuje možnosť kvapaliny pod tlakom dosiahnuť miesta, kde sa má uzavrieť voľný koniec 6 krčkovej časti 4.The aim of the first constriction is to prevent liquid under pressure from reaching the second constriction and hence to the free end 6, so that the laser closure can be carried out without the formation of holes with gas permeability. Indeed, both constrictions define an interior space that prevents or inhibits the possibility of the fluid under pressure to reach the points where the free end 6 of the neck portion 4 is to be closed.

Zúženie sa dá uskutočniť cirkulámou zápustkou alebo priamym zovretím.The constriction can be accomplished by a circular die or by direct clamping.

Ak sa má bombička použiť v spojitosti s injekčnou striekačkou bez ihly, potom kvapalnou náplňou bude hélium pod tlakom najmenej 30.106 Pa.If the cartridge is to be used in conjunction with a needle-free syringe, the liquid filling will be helium at a pressure of at least 30.10 6 Pa.

Je úplne jasné, že sú tu možné aj iné použitia, kedy bombička bude obsahovať plyn alebo kvapalinu pod tlakom podstatne nižšom, ako je 30.106 Pa.It is clear that other uses are possible where the cartridge will contain a gas or liquid at a pressure substantially lower than 30 bar.
