Abstract

LA MICROPIPETTE COMPREND UN CORPS FORMANT POIGNEE, UNE TIGE POURVUE D'ENTAILLES EQUIDISTANTES L'UNE DE L'AUTRE ET PLACE A L'INTERIEUR DU CORPS, UNE SERINGUE POUVANT ETRE BLOQUEE SUR CE DERNIER, ET DES MOYENS POUR FAIRE DEPLACER PAR PAS LEDIT ELEMENT EN FORME DE TIGE, ACTIONNES PAR UN BOUTON-POUSSOIR. SELON L'INVENTION, LA TIGE 4 TRAVERSE LONGITUDINALEMENT LE CORPS 1 ET PORTE A UNE EXTREMITE UN PISTON 6 COOPERANT AVEC LA SERINGUE 46; LES MOYENS DE DEPLACEMENT PAR PAS COMPRENANT UN COULISSEAU 21 S'ENGAGEANT DANS DES ENTAILLES CONSECUTIVES 6 DE LA TIGE; UN CLIQUET 12 PEUT OSCILLER D'UNE PREMIERE A UNE SECONDE POSITION, ET INVERSEMENT; CE CLIQUET EST PORTEUR DU COULISSEAU ET SON OSCILLATION EST COMMANDEE PAR UN BOUTON-POUSSOIR 7; DES ORGANES DE REGLAGE 24 REGLENT LA COURSE DU BOUTON-POUSSOIR EN FONCTION DE L'OSCILLATION DESIREE DU CLIQUET ET DE L'ENGAGEMENT RESULTANT DU COULISSEAU LE LONG D'UNE OU DE PLUSIEURS DES ENTAILLES.THE MICROPIPETTE INCLUDES A BODY FORMING A HANDLE, A ROD PROVIDED WITH EQUIDISTANT NOTCHES WITH ONE OF THE OTHER AND PLACED INSIDE THE BODY, A SYRINGE THAT CAN BE LOCKED ON THE LATTER, AND MEANS TO MOVE THE ELEMENT IN STEPS ROD SHAPED, ACTED BY A PUSH BUTTON. ACCORDING TO THE INVENTION, THE ROD 4 CROSSES LONGITUDINALLY THE BODY 1 AND AT ONE END A PISTON 6 COOPERATING WITH THE SYRINGE 46; THE MEANS OF MOVEMENT BY STEP INCLUDING A SLIDER 21 ENGAGING IN CONSECUTIVE SLOTS 6 OF THE ROD; A RATCHET 12 MAY OSCILLATE FROM A FIRST TO A SECOND POSITION, AND REVERSE; THIS RATCHET CARRIERS THE SLIDER AND ITS OSCILLATION IS CONTROLLED BY A PUSH BUTTON 7; ADJUSTING COMPONENTS 24 ADJUST THE PUSHBUTTON STROKE ACCORDING TO THE DESIRED RATCHET OSCILLATION AND THE ENGAGEMENT RESULTING FROM THE SLIDER ALONG ONE OR MORE OF THE NOTCHES.
