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.

An apparatus including tubing sets, a modular constraint assembly, and methods of use are described for deliver a therapeutic medication to a patient, the apparatus can have a controller and a sensor. The controller is configured to receive data from the sensor, and to start and stop delivery of the therapeutic medication to the patient in response to data received from the sensor. In addition, apparatus, systems and methods are disclosed, which are configured to deliver a therapeutic medication to a patient. The apparatus, system and methods use a reservoir, a patient interface, a tubing set, a modular constraint assembly connected to the tubing sets, and a fluid pump, and the components are configured to provide a calibrated flow rate based upon specific characteristics of the therapeutic medications passing through and internal lumen of the tubing set.

The present disclosure provides a needle assembly and a drug injection device including a needle, a cannula into which the needle is inserted, a first holder supporting the needle, a second holder disposed to face one side of the first holder and supporting the cannula, a sleeve accommodating the first holder in an inner space and rotating with respect to the first holder, and an elastic member disposed between the first holder and the sleeve, wherein, when the sleeve is rotated, the elastic member is expanded and the first holder and the second holder are moved to an extended position, and wherein, when the sleeve is further rotated, the elastic member is contracted and only the first holder is returned to an original position.

A system and method are provided to monitor performance of an intraosseous device by using a supporting structure and an attachment mechanism. The attachment mechanism releasably secures the supporting structure proximate an insertion site for the intraosseous device. The supporting structure includes an opening formed therein and sized to receive at least a portion of the intraosseous device. A sensor detects parameters associated with providing fluids and/or medications through the intraosseous device to the bone marrow. The attachment mechanism and the supporting structure cooperate with each other to minimize movement of the intraosseous device relative to the insertion site when the portion of the intraosseous device is disposed in the opening of the supporting structure.

Systems and methods for navigating a catheter and delivering a needle to a desired anatomic location are provided. The system includes an injection catheter that includes a needle slidably exposed from, or retracted into, the catheter lumen. The system further includes a first acoustic marker located at a distal end of the catheter and configured to generate an acoustic signal, and a second acoustic marker located at the distal end of the retractable needle and configured to generate an acoustic signal. The acoustic markers allow, in conjunction with a Doppler ultrasound imaging system, identification and navigation of an injection catheter and delivering a needle to a desired anatomic target location.

A medical connector for use in a fluid pathway includes a substantially transparent housing having a proximal end with a proximal opening and a distal end with a distal opening, and a cavity extending therebetween. The connector provides a substantially visible fluid flow path extending through a substantial portion of the connector.

Systems and methods for automatic flow termination for fluid delivery, including a housing configured for coupling a fluid delivery tube to a needle configured for subcutaneous delivery of fluid within a tissue of a patient and a spring-loaded activation mechanism having a first orientation corresponding to a condition where the housing is disposed substantially adjacent to the tissue and the needle lodged within the tissue and a second orientation corresponding to a condition where the housing is disposed away from the tissue or the needle being dislodged from the tissue. A flow termination mechanism is coupled to the activation mechanism and having an open configuration allowing flow from the fluid delivery tube to the needle when the activation mechanism is in the first orientation and a closed configuration substantially terminating flow from the fluid delivery tube to the needle when the activation mechanism is in the second orientation.

Devices and methods are provided for automatic vascular access. An automatic vessel cannulation device, mechanical or electronic, has a sensor configured to detect a physiologic parameter of a needle tip, and a blunting device advancing member released in response to the sensor. The sensor may measure pressure or any other physiological parameter. A processor is configured to analyze data sent by the sensor and is pre-set to identify parameters unique to arteries, veins, or other body cavities or organs. A method may include comparing a physiologic parameter with pre-determined parameters to deploy a blunting element if the physiologic parameter is within a range of the pre-determined parameters. An expandable sheath may be included. A device can be provided having a motor controlling the cannulation device orientation to scan tissue with the tip of the needle by moving the cannulation device through the ultrasound transducer.

A system for confirmation of fluid delivery to a patient at the clinical point of use is provided. The system includes a wearable electronic device. The wearable electronic device has a housing; at least one imaging sensor associated with the housing; a data transmission interface; a data reporting accessory for providing data to the user; a microprocessor for managing the at least one imaging sensor, the data transmission interface, and the data reporting accessory; and a program for acquiring and processing images from the at least one imaging sensor. The system further includes a fluid delivery apparatus; and one or more identification tags attached to or integrally formed with the fluid delivery apparatus. The program processes an image captured by the at least one imaging sensor to identify the one or more identification tags and acquires fluid delivery apparatus information from the one or more identification tags.
