Patent

CA 2094351

A belt driven infusion pump for emptying the contents of a syringe is disclosed. The pump includes a syringe pusher including an antisiphon catch and a pressure detector which is used for detecting occlusions or the end of infusion. A syringe clamp for locking a syringe in place is also provided. The syringe clamp is spring-loaded and lockable. A syringe position detector is provided to ensure the proper placement of the syringe prior to and during pumping. A control knob is provided on the face of the pump for controlling both the locking of the syringe barrel clamp and the coupling of the drive belt with a d.c. motor. The pump includes a housing having an elongated slot through which the syringe pusher is connected to the drive belt. A sealing band is connected to the syringe pusher and is moveable with the syringe pusher for sealing the slot against moisture or other contaminants. A pole clamp assembly is incorporated within the pump housing and includes a clamping arm for securing the pole between the clamping arm and the housing. The clamping arm is movable to a storage position where it is substantially flush with the outer surface of the pump housing.

Cette invention concerne une pompe à perfusion commandée par courroie d'entraînement et servant à vider une seringue de son contenu. La pompe comporte un pousse-seringue à organe anti-siphonnage et détecteur de pression servant à détecter les occlusions et la fin de la perfusion. Un porte-seringue permettant de verrouiller en place une seringue est également prévu. Il est à ressort et verrouillable. Un détecteur de position de seringue sert à garantir le bon positionnement de la seringue avant et pendant la perfusion. Un bouton de commande monté sur le dessus de la pompe sert à verrouiller la seringue en place et à commander l'accouplement de la courroie d'entraînement avec le moteur c.c. de la pompe. Celle-ci comporte une enveloppe à ouverture allongée à l'intérieur de laquelle le pousse-seringue est raccordé à la courroie d'entraînement. Une bande de scellement solidaire du pousse-seringue suit celui-ci dans son déplacement pour empêcher l'humidité et d'autres contaminants de pénétrer dans l'ouverture allongée susmentionnée. L'enveloppe de la pompe est munie d'un clip de montage sur support à solutés comportant un doigt de serrage totalement escamotable.
