A catheter system may include a catheter assembly. The catheter assembly may include the catheter adapter, which may include a distal end, a proximal end, an inner surface forming a lumen, the lumen extending through the distal end and the proximal end, and a side port disposed between the distal end and the proximal end. The catheter assembly may include an annular valve, which may be disposed within the lumen and aligned with the side port. The annular valve may seal a fluid pathway from the side port to the lumen. The catheter assembly may include a retainer ring disposed proximal and/or proximate the annular valve within the lumen. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter.

A compartmentalized syringe configured to retain both the medicine and the flushing solution in the same housing. At least one smaller fluid or solid containing container will be added inside the flush housing and will separate its content(s) from other fluids or solids inside the flush housing. The shape of the housing and inner containers can be similar with the outer syringe flush with channels to facilitate the flow of fluids and they can also be of different shapes which will automatically create channels to allow the flow of fluid. An opening in the syringe plunger configured to receive a medicine vial.

An intravenous (IV) fluid delivery system include an IV bag and a fluid delivery device. The IV bag is made of many fluidic channels that keep the fluid distributed across the bag such that the bag may be easily and comfortably wrapped around the arm and shoulder of a person. The fluid delivery device includes a processor controlled electromechanical delivery mechanism that controls a positive displacement pump. The pump moves the fluid into a tube and a needle that is connected to a person's vein. The processor repeatedly turns the pump on or off to gradually transfer the fluid from the IV bag into the person's vein. The processor controls the granularity of the fluid delivery, where the fluid may be administered in a fluid delivery period, the fluid delivery may then be stopped in a subsequent fluid stoppage period, followed by other fluid delivery periods.

IV filters are described herein. An IV filter includes a body, a filter media, and a bulb. The body defines a body volume. The filter media is disposed within the body volume. The filter media defines an inlet portion of the body volume and an outlet portion of the body volume. The filter media permits inlet flow from the inlet portion of the body volume to the outlet portion of the body volume and captures particulate from the inlet flow. The bulb defines a bulb volume in fluid communication with the outlet portion of the body volume. The bulb is deformable to compress the bulb volume and direct back flow from the outlet portion of the body volume through the filter media and into the inlet portion of the body volume, displacing particulate captured in the filter media into the inlet portion of the body volume.

An IV catheter device can include or being configured to employ a probe assembly having an integrated fluid flushing mechanism. The probe assembly can be configured in a variety of ways to cause flushing fluid to be injected through a fluid permeable structure of the probe as the probe is advanced distally from a catheter. In this way, the fluid permeable structure can be kept clear of any occlusion that may otherwise form. With the probe extending distally from the catheter, a blood sample may be collected.

A syringe assembly includes (i) a syringe with a cylindrical body, luer tip at a first end, finger grip at a second end and a cannula extending from the luer tip into the cylindrical body, and (ii) a plunger unit having an adapter portion, receiving cavity, finger grip and piston. A channel extends the length of the adapter portion to receive the cannula in one end and a variety of connectors, valves and/or syringes in a second end. The end of the channel accessible in the receiving cavity mates with or engages any number of commercially available valves, connectors and/or syringes while the luer tip similarly connects to any number of valves, catheters, connectors, etc., depending on the task being undertaken with the syringe assembly.

Apparatus and methods for providing controlled pressure-flow pulses which purge a catheter system with turbulent flow flushing. Accomplishment of such controlled pressure-flow pulses is provided by a variety of inventive devices including a special plunger rod for a conventional syringe, other interactive parts for conventional syringes, an in-line catheter attachable device which automatically generates the controlled pressure-flow pulses and also single pulse, digitally operated devices.

An injection setup kit can include a manifold connector, a first packaging container, and a fluid line. The first packaging container can define a first closed interior volume that includes a patient interface connector having a patient interface inlet, a first patient interface outlet, and a valve configured to selectively permit fluid communication through the patient interface connector. The patient interface inlet can be fluidly connected to the manifold outlet. The fluid line can have a first fluid line end and a second fluid line end. The first fluid line end can be connected to the patient interface inlet within the first closed interior volume. The second fluid line end can extend outside of the first closed interior volume and be connected to a manifold outlet outside of the first closed interior volume.

A patency checking system, may include a fluid path to be coupled to an intravenous (IV) device at a distal end of the fluid path; a patency port formed along a length of the fluid path; and a plunger fluidically coupled to the fluid path at the patency port to selectively draw blood into the fluid path to confirm patency of the fluid path.

A method may include obtaining, with a first temperature sensor, a first temperature measurement at a first location on a body of a patient adjacent a catheter insertion site of a catheter; obtaining, with an array of temperature sensors, a plurality of temperature measurements at a plurality of locations on the body of the patient, each of the plurality of locations being spaced apart from the first location, and the plurality of locations including locations at a plurality of different distances from the first location; determining, with at least one processor, based on the first temperature measurement and the plurality of temperature measurements, an alert condition associated with a dressing and/or securement device and/or the catheter; and in response to determining the alert condition, generating, with at least one processor, an alert to a user.
