20100179476 | CONVEYING DEVICE IN OR FOR AN APPARATUS FOR ADMINISTERING A DRUG - A conveying device in or for an apparatus for administering a product, including a base, a first conveying member which can be moved relative to the base and includes a first thread, a second conveying member which can be moved relative to the base and includes a second thread for a threaded engagement with the first thread, wherein the second thread extends over an axial portion of the second conveying member which is radially flexible in relation to its threaded axis, such that one of the conveying members can be axially inserted into the other in an overlap of the threads, and a blocking member which can be moved relative to the base, wherein one of the blocking member and the second conveying member can be moved relative to the other into a blocking position in which the blocking member radially stiffens the second thread in the threaded engagement in the region of the flexible axial portion and thus secures the threaded engagement. | 07-15-2010 |
20100185151 | DEVICE FOR PREVENTING A FREE CATHETER FLOW - A catheter for connecting an administering device to an administering needle, the catheter including a catheter wall, a flow region limited by the catheter wall, and at least one catheter portion at which at least one partial piece of the catheter wall abuts at least one other partial piece of the catheter wall to releaseably block or obstruct the flow of a medium through the catheter, wherein the flow is unblocked or opened when the medium exhibits a pressure above a predetermined blocking pressure. | 07-22-2010 |
20100204661 | LEAF SPRING VALVE AND CONE MEMBRANE VALVE - A delivery device and a method for administering a fluid from a fluid reservoir, wherein an unintended free flow of the fluid from the reservoir to a recipient is reliably prevented, are disclosed. The delivery device has a tank for the fluid; a fluid delivery device which delivers the fluid from the tank; a valve body providing an input hole and an output hole; and an infusion set in order to guide the fluid from the tank to a distal end of the delivery device. The delivery device further provides a shutter assembly which is or can be mounted to the valve body and prevents the fluid from flowing inside the infusion set when the fluid exhibits a pressure which is lower than a predefined pressure. | 08-12-2010 |
20110144615 | METHOD AND DEVICE FOR MICRO-DOSING A LIQUID - Methods and devices for micro-dosing a liquid are disclosed herein. According to one embodiment, a method for a time controlled micro-dosing of a liquid from a liquid reservoir includes: receiving the liquid reservoir with a structure wherein the structure is portable; securing the liquid reservoir to the structure; connecting a second end of a drive unit to a piston disposed within the liquid reservoir; activating a drive motor; displacing the drive unit with respect to the structure towards the piston in an axial direction with the drive motor; moving the piston axially within the liquid reservoir; and micro-dosing the liquid from the liquid reservoir. | 06-16-2011 |
20120179116 | Device For Preventing A Free Catheter Flow - A catheter for connecting an administering device to an administering needle, the catheter including a catheter wall, a flow region limited by the catheter wall, and at least one catheter portion at which at least one partial piece of the catheter wall abuts at least one other partial piece of the catheter wall to releaseably block or obstruct the flow of a medium through the catheter, wherein the flow is unblocked or opened when the medium exhibits a pressure above a predetermined blocking pressure. | 07-12-2012 |
20130221023 | METHOD AND DEVICE FOR MICRO-DOSING A LIQUID - Methods and devices for micro-dosing a liquid are disclosed herein. According to one embodiment, a method for a time controlled micro-dosing of a liquid from a liquid reservoir includes: receiving the liquid reservoir with a structure wherein the structure is portable; securing the liquid reservoir to the structure; connecting a second end of a drive unit to a piston disposed within the liquid reservoir; activating a drive motor; displacing the drive unit with respect to the structure towards the piston in an axial direction with the drive motor; moving the piston axially within the liquid reservoir; and micro-dosing the liquid from the liquid reservoir. | 08-29-2013 |
20130261599 | Dosing Unit With Safety Valve - A valve for an infusion pump device comprising a pump connection fluidly connected to a piston pump, an infusion site connection fluidly connected to an infusion set, and a reservoir connection fluidly connected to a reservoir is presented. The valve is in a first state (I) when the pump connection is fluidly connected to the infusion site connection and the reservoir connection is sealed closed and in a second state (II) when the pump connection is fluidly connected to the reservoir connection and the infusion site connection is sealed closed. The valve comprises one or more conduits, grooves, and/or recesses connected to environment and arranged so that no path exists within the valve between the infusion site connection and the reservoir connection that does not cross at least one of the conduits, grooves, and/or recesses, establishing a drain, independently if a path is closed during normal operation of the valve. | 10-03-2013 |
20140180210 | Dosing Unit for an Ambulatory Infusion Device - A dosing unit for an infusion pump device is disclosed having a piston pump with a pump cylinder and a plunger arranged within said cylinder, coaxially arranged along a longitudinal axis. The plunger has a shaft with a thread and the cylinder has a threaded sleeve part with a thread. The two threads engaging with each other in such a way that a rotational movement of the plunger around the longitudinal axis results in an additional linear displacement of the plunger along said longitudinal axis. A separate bias force element biases the two threads in regard to each other along the longitudinal axis, such that the threaded engagement of inner thread and outer thread is free of play independent of a direction of a rotational movement and linear displacement of the plunger in regard to the cylinder. | 06-26-2014 |
20140364808 | SPRING FORCE ASSEMBLY FOR BIASING OR ACTUATING STOPPERS OF SYRINGES, INJECTION PEN CARTRIDGES AND THE LIKE - A spring force assembly for biasing a displaceable stopper of a liquid medicament cartridge including a spring element arranged along a longitudinal axis, with brace elements and coupling elements, with the coupling elements restricting the distance between the brace elements which also restricts the possible expansion of the spring element. | 12-11-2014 |
