Abstract: In an elongated casing, an active agent container connected to an injection needle can be shifted axially by a spring force. Auto-injectors which are sold or distributed filled and with the springs tensed have to be provided with a needle protecting cap to ensure the sterility of the injection needle. When such a needle protecting cap is removed as preparation for using the auto-injector, a tensile force can be exerted on the active agent container. Therefore, the active agent container comprising the injection needle must be prevented from being undesirably pulled forwards. At least one latching tongue prevents the active agent container from being prematurely shifted with respect to the casing, by abutting a flange arranged on a sliding sleeve which accommodates the active agent container. When the auto-injector is placed onto a person's skin, a needle protecting tube is shifted into the casing, forcing the latching tongue away from the flange and, thus, freeing the travel path for needle movement.
Abstract: An apparatus, method and program product detects an occlusion in a fluid line by determining if a relationship between force measurements departs from an expected relationship.

Abstract: Tools for determining and adjusting the setting of an adjustable valve are disclosed. These tools allow a medical professional to locate and non-invasively determine the setting of an implanted valve. After the valve has been located and the setting of the valve determined, the valve may be re-adjusted non-invasively. There are three tools: a locator tool, an indicator tool and an adjustment tool. The locator tool allows the physician to locate the adjustable valve of interest and align the locator tool with a specific orientation of the valve. The indicator tool indicates the current setting of the adjustable valve and confirms new settings of the valve after the new settings have been implemented. The adjustment tool interacts magnetically with the implanted adjustable valve to couple with a movable internal element to change the setting of the valve. The indicator tool and the adjustment tool physically cooperate with the locator tool to accomplish the respective functions of the tools.

Abstract: Infusion systems and methods for infusing one or more drugs or other agents into the body of a human or animal subject. The system is programmed to take remedial action(s) upon sensing of a fault or error in connection with the infusion. In some embodiments, an agent may be infused through redundant flowpaths and, if a fault occurs in one flowpath, the system may respond by increasing flowrate through other non-faulting flowpath(s). In some embodiments, the fault may be a physiological reaction or symptom in the subject and the system may respond by adjusting or stopping flowrate(s) or one or more agents or changing the ratio of simultaneously infused agents.
Abstract: The present invention discloses an anti-free flow mechanism for a finger-type peristaltic infusion pump (DDS) and methods for avoiding anti-free-flow. The mechanism comprises: a passive mechanical interface (MS) which integrally accommodates a portion of the flexible infusion tube, and an anti-free flow valve (AFFV) which is a spring-activated latch, which is incorporated within said MS. The maneuverable latch is secured in the MS either in CLOSED or OPEN configurations: in its CLOSED configuration no flow is provided, and in its OPEN configuration, a free flow is facilitated. Said anti-free flow mechanism is configured in a manner such that when the MS is not properly mounted in the DDS, said AFFV is automatically actuated via one or more integrated springs, to its CLOSED configuration. When the MS is properly mounted in the DDS, said latch is adapted to be automatically switched to the OPEN configuration.
