| 20100296955 | LINEAR PERISTALTIC PUMP WITH FINGERS AND MEMBRANE AND FINGER FOR SUCH A PUMP - The invention relates to a linear peristaltic pump with fingers comprising a membrane positioned between the pumping fingers ( | 11-25-2010 |
| 20100268161 | CLAMP FOR A FLEXIBLE TUBE, PUMP PROVIDED WITH MEANS FOR OPENING SUCH A CLAMP, AND INFUSION KIT PROVIDED WITH SUCH A CLAMP - The invention relates to a clamp ( | 10-21-2010 |
| 20100065700 | LOCK FOR FIXATION DEVICE - The invention relates to a device ( | 03-18-2010 |
| 20100040481 | DEVICE FOR CONTROLLING THE OPENING AND CLOSING OF A CLAMP IN A POSITIVE DISPLACEMENT PUMP - A device for controlling the opening and closing of a clamp intended to seal a flexible tube, for example in a positive displacement pump, includes: a housing that can be closed with a door; a tube placed inside the housing; a clamp also placed in the housing, which cooperates with the tube to open or seal it. The clamp is closed when the door is being opened and when the door is being closed. As well as ensuring that the tube is always closed when the door is being opened, the inventive safety device also ensures that the tube remains closed once the door has been closed as long as a suitable device does not trigger the opening of the clamp. The fully mechanical closure device is not exposed to the dangers of a faulty power supply. | 02-18-2010 |
| 20100021315 | METHOD FOR CONTROLLING THE CAPACITY OF A PERISTALTIC PUMP AND PERISTALTIC PUMP - A method for controlling the flow rate of a peristaltic pump includes compressing a flexible tube, forming at least one occlusion region that moves cyclically downstream from the upstream end of the pump, and compressing the tube in the direction of a counter surface to form an occlusion. A peristaltic pump can be used to carry out the method so as to suppress reverse flow without altering the speed of the motor. The occlusion in the most downstream part of the pump remain in the occluding position for a longer portion of the cycle than occlusion in a more upstream part of the pump, preferably for longer than the compression in the most upstream part of the pump. | 01-28-2010 |
| 20080262440 | Holding Device for Locking the Head of a Syringe Piston on a Syringe Pump Pusher - A holding device for locking the head of a syringe piston on a pusher has arms connected to respective pinions pivotable and translationally displaceable so that the corresponding arm is involved in the same motion between a rest position, in which the arms are closed and pressed against the pusher, and an open position, in which the arms are opened and remote therefrom, the translation is carried out prior to rotation during the movement toward the open position or in reverse order toward the rest position. The holding device also has a control member and means for converting a part of the control member movement by transmitting it to at least one pinion as a translation movement, which are translationally locked, and means for converting a part of the control member movement by transmitting it to at least one pinion as a rotation movement. | 10-23-2008 |
