Connectors for medical devices include visual and tactile features as an indicator of a connection-type of the connector. This allows for differentiation by type of connection under busy and/or low light conditions.

A catheter control system the system can include a control unit having a first connection port. The control unit can have a first visual indicator associated with the first connection port. The system can also include a first catheter interface connector connected to the first connection port of the control unit. The first catheter interface connector can have a first visual indicator corresponding to the first visual indicator on the control unit. The first visual indicator on the first catheter interface connector can be to be active to indicate that the first catheter interface connector is connected to the first connection port on the control unit.

An acoustic line tracing system for tracing a fluid transfer system tubing line includes an acoustic receiver operably connectable to the tubing line and configured to receive the vibratory signal. The acoustic receiver includes a vibration sensor disposed to contact the tubing line and configured for detecting vibration of the surface of the tubing line caused by the vibratory signal, and an indicator producing at least one of an audio and a visual cue when the vibration sensor detects the vibratory signal.

Percutaneous access apparatus is described that includes a percutaneous fluid access device having an extracorporeal portion, one or more ports accessible from the extracorporeal portion and a septum for sealing each port. A connector device having one or more hollow needles is attachable to the percutaneous fluid access device. The apparatus also includes an attachment mechanism for attaching the connector device to the extracorporeal portion and an actuation mechanism that, after the connector device has been attached to the extracorporeal portion, can be used to drive the one or more hollow needles through the septum to establish fluid communication between the one or more hollow needles and the one or more ports. The apparatus may be used for neurosurgery applications.

This invention relates to new apparatuses for draining material from a stomach and infusing fluid into the stomach comprising a tubing connector, a housing unit, and a one-way valve. In an embodiment the connector can have a first port, a second port, a third port and a branched lumen that extends through each of the first, second and third ports. The housing unit can have a housing lumen that is sized and shaped to receive the third port and the housing unit is sized and shaped to receive the connector. The one-way valve can be sized and shaped to be received in the housing lumen.

Present invention relates to a medical device control system (100) comprising a medical device (120) and a controller device (110) configured to control the operation of the medical device (120), the medical device control system (100) further comprising a coupling assembly (300) for connecting the medical device (120) and the controller device (110). The coupling assembly (300) comprises a connector (330) and a connecting member (310), the connector (330) being connectable to the connecting member (310) for forming a connection through said connector (330) and connecting member (310). The coupling assembly (300) comprises an identification device (390), said identification device (390) being adapted to generate a characteristic response associated with the controller device (110) or the medical device (120). The medical device control system comprises a sensing arrangement (420) being configured to emit a sensing signal (S) in the form of a mixed radio frequency waveform by combining a carrier signal (C) and a mixing signal (M) for detecting the characteristic response.

A medium connector including a passage configured to allow for the flow of medium, and a multi-portion engagement surface positioned about the passage. The multi-portion engagement surface includes a first surface portion, and a second surface portion. The first surface portion is configured to provide an interference fit with a corresponding sealing surface of a mating connector. The second surface portion is configured to provide a clearance fit with the corresponding sealing surface of the mating connector. The ratio of the first surface portion and the second surface portion is selected to regulate an engagement force between the medium connector and the mating connector.

A tube-joining device for joining two flexible tube sections including a tube holder configured to hold the flexible tube sections in place for joining. The tube holder may have a clamped and a non-clamped configuration. The tube holder may have a start and a finish configuration. The tube holder may have tube detectors. When certain criteria are met, the tube holder may automatically begin a tube-joining operation, or may automatically return itself from the finish to the start configuration, or the tube-joining device may automatically begin heating a blade used for cutting and melting the tubes.

A connector includes an outer connector, an inner connector, and a clutch that can collectively limit a torque transmitted through the connector, the outer connector can include a profile disposed on an inner surface thereof, and the inner connector may be disposed within the outer connector and can include an upper threaded portion and a lower threaded portion. The clutch can be disposed around and rotationally coupled to the inner connector and can include a plurality of clutch teeth extending from an outer surface of the clutch, wherein the plurality of clutch teeth are outwardly biased to be releasably engaged with the profile of the outer connector, and the plurality of clutch teeth can be configured to transfer torque from the outer connector to the inner connector when the torque is below a torque limit and prevent transfer of torque when the torque exceeds the torque limit.

An infusion pump assembly (1) includes a housing (14) with a fluid reservoir (18) and an opening (22) to receive a connector (100) of an infusion set to fluidly connect to the reservoir. The assembly includes a switch assembly (70) that transitions between a connected state when the connector is inserted within the opening and a disconnected state when the connector is removed from the opening. An infusion set connects to the infusion pump. The infusion set can have a connector having a body including an outer wall that defines an outer perimeter and a wall cross-sectional shape that corresponds with a cross-sectional shape of an opening of the housing.
