Title (EN) MEDICATION INFUSION DEVICE USING NEGATIVELY BIASED AMBIENT PRESSURE MEDICATION CHAMBER
(FR) DISPOSITIF D'INFUSION DE MEDICAMENT UTILISANT UNE CHAMBRE DE MEDICAMENT SOUS PRESSION AMBIANTE NEGATIVEMENT SOLLICITEE
Abstract:
(EN) A method and apparatus of infusing medication into a patient's body using a medication chamber referenced to ambient pressure. The apparatus includes a medication chamber (50) enclosed by a peripheral wall (44) which includes a movable portion configured to transfer exterior ambient pressure into the chamber. Means are provided for exerting a negative biasing force acting on the movable portion in a direction opposed to the ambient pressure force. Thus, the resultant pressure in the chamber will be negative with respect to ambient pressure, reducing the risk that the chamber can be overpressurized and produce an unintended medication discharge.
(FR) L'invention concerne un procédé et un appareil permettant d'infuser un médicament dans le corps d'un patient au moyen d'une chambre de médicament sous pression ambiante. Ledit appareil comprend une chambre de médicament entourée d'une paroi périphérique pourvue d'une partie mobile, configurée afin de transférer une pression ambiante extérieure dans ladite chambre. Des moyens sont prévus pour exercer une force de sollicitation négative agissant sur la partie mobile dans un sens opposé à la force de la pression ambiante. De ce fait, la pression résultante dans la chambre sera négative par rapport à la pression ambiante, ce qui réduit le risque de surpression de ladite chambre et la production d'une décharge imprévue de médicament.
