Abstract | A fluid vessel insertion device (10), typically for medical use, comprises a puncture member (18) arranged for location within a sleeve (20), and a retraction mechanism (44, 48, 60) for retracting the puncture member relative to the sleeve. The puncture member (18) is retractable in use between a first condition in which an end (18A) of the puncture member protrudes beyond an end (24) of the sleeve and a second condition in which the end of the puncture member is within the sleeve (20). The retraction mechanism (44, 48, 60) actuates the puncture member between the first and second conditions in response to fluid pressure at the end (18A) of the puncture member. The device may be used during positioning of the sleeve in a desired fluid vessel, such as, for example, during intravenous cannulation.
La présente invention concerne un dispositif d'insertion de cuve de fluide (10), typiquement pour utilisation médicale, qui comprend un composant de piqûre (18) agencé pour localisation dans un manchon (20), et un mécanisme de retrait (44, 48, 60) pour retirer le composant de piqûre par rapport au manchon. Le composant de piqûre (18) est rétractable en utilisation entre une première condition dans laquelle une extrémité (18A) du composant de piqûre fait saillie au-delà d'une extrémité (24) du manchon et une deuxième condition dans laquelle l'extrémité du composant de piqûre est dans le manchon (20). Le mécanisme de retrait (44, 48, 60) actionne le composant de piqûre entre les première et deuxième conditions en réponse à la pression de fluide à l'extrémité (18A) du composant de piqûre. Le dispositif peut être utilisé pendant le positionnement du manchon dans une cuve de fluide souhaitée, tel que, par exemple, pendant une canulation intraveineuse. |
