    Abstract: An infusion system includes a catheter with a proximal end, distal end, at least one lumen between the proximal end and distal end, and outlets. Each outlet connects to the at least one lumen to convey fluid, and extends radially through a catheter wall of the catheter. The outlets are spaced apart from in the proximodistal direction, and include a first outlet and a second outlet. The first outlet is opened independently of a fluid pressure prevailing in the lumen in order to administer an analgesic. The second outlet is adapted for fluid pressure-dependent administration of the analgesic and capable of being converted, as a function of fluid pressure inside the lumen, between an opening state, in which the second outlet is opened to administer the analgesic, and a closure state, in which the second outlet is closed. The infusion system can be used in pain management.

    Abstract: An infusion arrangement for administering a medical fluid includes a medical elastomer pump that produces a delivery pressure dependent on expansion and thus is variable over an infusion duration, a fluid conduit path provided for discharging the medical fluid from the elastomer pump, and a fluid control device arranged in the fluid conduit path and designed to influence a volumetric flow of the medical fluid delivered through the fluid conduit path by the elastomer pump. The fluid control device has a hydraulic flow-regulating valve designed to regulate the volumetric flow to a setpoint value and is provided with a throttle action that is automatically variable at least in accordance with the delivery pressure. The infusion arrangement can be used in infusion therapy.

    Abstract: A fluid transfer device for use in medical/pharmacological applications a method of use, and a closed medicine transfer system. The fluid transfer device includes a first adapter unit having a first sealing element and a second adapter unit having a second sealing element. The first adapter unit and second adapter unit, when connected, provide a fluid connection between the first adapter unit and the second adapter unit and prevent, when disconnected, the transfer of fluid out of the first adapter unit and the second adapter unit. A fluid connection between the first adapter unit and second adapter unit is established by a combined pressing movement towards one another and a rotational movement with respect to one another, only after a constant pressure has been set which the first sealing element and the second sealing element apply against each other.

    Abstract: A catheter, which can be used in infusion therapy, includes a catheter tube having a main lumen and at least one secondary lumen. The main lumen and the at least one secondary lumen are each elongate between a proximal tube end and a distal tube end. The at least one secondary lumen has a lateral opening arranged between the proximal tube end and the distal tube end in an axial direction of the catheter tube. The lateral opening extends through a tube casing of the catheter tube in a radial direction of the catheter tube. A seal is introduced into the at least one secondary lumen distally behind the lateral opening and at least partially seals the secondary lumen. The seal is formed from a sealing compound cured in the at least one secondary lumen or a thermoplastic elastomer material expanded within the at least one secondary lumen.

    Abstract: A connecting system for medical applications, which can be used in medical technology, particularly in the field of oncology, includes a male connector and a complementary female connector. The male connector has a plug and an annular wall that concentrically encloses the plug while forming an annular gap. The male connector also has an internal thread facing toward the plug. The female connector has a socket complementary to the plug and an external thread complementary to the internal thread. The female connector is inserted into the annular gap of the male connector in a connected state. An inactive adhesive arrangement is provided in the annular gap and assigned an activation system, in such a way that activation of the adhesive arrangement takes place as a result of insertion of the female connector into the annular gap of the male connector.

    Abstract: A tube connector for an infusion tube is connectable to an infusion container. The tube connector has a first fluid opening that is connectable to the infusion tube or to a drip chamber connected to the infusion tube to provide a first fluid connection between the infusion container and the infusion tube. The tube connector has a second fluid opening connectable to the infusion tube to provide a second fluid connection between the infusion container and the infusion tube. The tube connector has a blocking device configured to block a fluid connection between the infusion tube connected to the second fluid opening and the infusion container connected to the tube connector to prevent a release of fluid from the infusion container into the infusion tube.
