Title (EN) METHODS AND APPARATUS FOR MEASURING ASPIRATION PRESSURE
(FR) PROCÉDÉS ET APPAREIL POUR MESURER UNE PRESSION D’ASPIRATION
Abstract:
(EN) An aspiration apparatus adapted to allow aspiration verification of a liquid such as of a biological liquid or reagent liquid, especially at low aspiration volumes (e.g., less than 25 μL). The apparatus includes a pump operable at an operating frequency, the pump optionally including a pumping chamber, a probe having a probe interior, a main supply line containing a backing liquid coupled to and extending from the pump and including the probe interior, a striction coupled to the main supply line, or the pump chamber, if present, and a reservoir fluidly coupled to the striction, wherein the striction is sized to minimize backing liquid flow through the striction at one or more disturbance frequencies above the operating frequency. Systems and methods for carrying out the liquid aspiration are provided, as are other aspects.
(FR) La présente invention concerne un appareil d’aspiration adapté pour permettre la vérification d’aspiration d’un liquide tel qu’un liquide biologique ou un liquide réactif, en particulier à de faibles volumes d’aspiration (par exemple, moins de 25 µl). L’appareil comprend une pompe pouvant fonctionner à une fréquence opérationnelle, la pompe comprenant facultativement une chambre de pompage, une sonde ayant un intérieur de sonde, une voie d’alimentation principale contenant un liquide de support couplée à et s’étendant depuis la pompe et comprenant l’intérieur de sonde, une striction raccordée à la voie d’alimentation principale, ou à la chambre de pompe, le cas échéant, et un réservoir en couplage fluidique avec la striction, la striction étant dimensionnée pour réduire au minimum l’écoulement de liquide de support à travers la striction à une ou plusieurs fréquences de perturbation au-dessus de la fréquence opérationnelle. L’invention concerne des systèmes et des procédés pour conduire l’aspiration de liquide, ainsi que d’autres aspects.
