The present technology relates to vascular access devices, systems, and methods configured to monitor a patient's health. In some embodiments, the vascular access device may include a sensing element, and the system of the present technology may be configured to obtain physiological measurements of the patient via the sensing element, determine at least one physiological parameter based on the physiological measurement, compare the at least one physiological parameter to a predetermined threshold, and, based on the comparison, provide an indication of the patient's health.

Methods, apparatus, and systems to non-invasively determine intra-luminal placement and patency of a vascular access device. Patency and/or placement are estimated indirectly by measuring a physiological parameter which is indicative of proper patency and/or placement of the vascular access device in a patient. The measurement is compared to a reference value or calibration. If the comparison indicates indication of proper patency and/or placement, a signal can be generated. The signal can be used in a number of ways. One example is to give a user-perceivable alarm or indication of proper patency and/or placement. Non-limiting examples include activating a light, an audible buzzer, a vibration, readable displayed text or graphics, or some combination of the same. The user can then have an indirect and at least semi-automatic way of estimating proper patency and/or placement of a vascular access device.

Various implementations include a system for coupling a needle to a port. The system includes a port and a needle. The port includes a reservoir and a lock box disposed within the cavity and defining a lock opening. The reservoir includes a membrane and a base coupled to the membrane, which together define a cavity. The reservoir is configured to be implanted under the skin of a person. The needle defines a lumen extending along a needle longitudinal axis. The needle includes a key disposed within the lumen. The key is movable from a first position to a second position. A portion of the key extends further in a radially outward direction in the second position than in the first position. A distal end of the needle is disposable within the lock opening such that the key is couplable to the lock box when in the second position.

An apparatus for use with an access port implanted in a living body includes a locator assembly. The locator assembly includes at least one port sensor configured to sense an aspect of the access port, at least one skin sensor configured to sense a proximity of the apparatus to a skin of the living body, and a controller configured to determine a location of the access port based on the aspect sensed by the at least one port sensor, where the controller instructs the at least one port sensor to sense the aspect based on the proximity of the apparatus to the skin as sensed by the at least one skin sensor. The locator assembly also includes an output device configured to provide user feedback, and the controller is further configured to instruct the output device to provide the feedback based on the determined location of the access port.

A medical tube comprises a tail to connect an embedded wire to an electrical component. The tail may comprise a flattened portion and an exposed portion to facilitate attachment of the medical tube to an electrical component. The tail may comprise a second flattened portion. One or more wires, such as a heater wire or a sensor wire, may be embedded in the medical tube. The medical tube may comprise a connector that comprises a printed circuit board to which the one or more wires is attached. The connector may comprise features to support the printed circuit board, aid in assembly of the one or more wires to the connector, and protect electrical components against liquid ingress.

A sheath for producing a fully sealed access to the interior of a vessel of an animal or human body comprises a base sheath having a tubular body defining a pass-through channel. The base sheath is adapted to be inserted into the vessel through a vessel aperture. A wall of the tubular body of the base sheath has a through channel. This channel extends in the wall from the distal end towards the proximal end. The channel can be present separately from the pass-through channel of the base sheath or can form a sideways extension of the pass-through channel, at least at the distal end. Such through channel is adapted to conduct blood from the vessel to the proximal end of the sheath when the sheath has been inserted into a vessel.

A dressing for protecting a vascular access catheter skin entry site including a foundation dressing module and a cover dressing module. The foundation dressing module includes a single or multi-part frame defining an aperture. The frame has a foundation dressing skin-facing surface and a foundation dressing opposing surface in opposition to the foundation dressing skin-facing surface. The cover dressing module includes a cover dressing skin-facing surface and a cover dressing non-skin facing surface, a hydroscopic pad on the cover dressing skin-facing surface adapted to area-fill the aperture. The cover dressing skin-facing surface is configured to be superimposable onto the foundation dressing opposing surface bringing the hydroscopic pad into direct fluid communication with a skin entry site of the vascular access catheter.

A base plate and/or a sensor assembly part for an ostomy appliance is disclosed, the base plate and/or the sensor assembly part comprising a first adhesive layer with a proximal side configured for attachment of the base plate and/or the sensor assembly part to the skin surface of a user, the first adhesive layer having a stomal opening with a center point; and a plurality of electrodes including a ground electrode, a first electrode, and a second electrode, the ground electrode comprising a ground connection part, the first electrode comprising a first connection part, and the second electrode comprising a second connection part; wherein the ground electrode forms a ground for the first electrode and the second electrode.

A surgical port includes an end face comprising a channel extending through the end face, the channel having a cross section shaped to receive a surgical instrument cannula, and a lateral wall extending around a perimeter of the end face, the lateral wall and end face enclosing an open volume. An end portion of a wound retractor is received in the open volume of the surgical port and in engagement with an inner surface of the lateral wall, and the surgical port is configured to abut a body wall in an inserted position of the wound retractor through the body wall.
