Drip chambers, burettes and other IV set components are described herein. An IV set component described herein comprises a chamber body, an inlet portion, and a disk valve. The chamber body defines a chamber volume and an outlet. The chamber volume is in fluid communication with the outlet. The inlet portion is coupled to the chamber body, the inlet portion defining an inlet, a priming port, a drip port. The inlet is in fluid communication with the priming port and the drip port, and the priming port and the drip port are each in fluid communication with the chamber volume. The disk valve is coupled to the inlet portion. The disk valve is movable to direct flow from the inlet to the priming port in a first position and to direct flow from the inlet to the drip port in a second position.

A circular roller clamp assembly includes a semi-circular housing configured to receive a portion of an IV tube, a motor and a motor arm coupled to the motor. A roller is coupled to the roller arm, the roller movably received by a guide groove disposed in the semi-circular housing. A flow rate of fluid flowing through the IV tube is regulated based on roller impingement of the IV tube against a tube channel in the guide groove via circumferential movement of the roller along the guide groove. IV sets with circular roller clamp assemblies and methods of operating circular roller clamp assemblies are also provided.

A clamping module of or for a medical pump, and a method for identifying a hose clamp of a disposable infusion article insertable into the clamping module. The clamping module includes an electro-optical system for identifying the hose clamp, which has an optical marking. The electro-optical system includes a first light source for emitting at least a first light beam and a second light source for emitting at least a second light beam. The second light source is formed differently than the first light source. A photodetector receives a reflected light, and an optical window bundles the first light beam and/or the second light beam on the disposable infusion article, as well as the reflected light received by the photodetector. The method identifies the hose clamp based on a color and uses a measurement algorithm after insertion of the hose clamp into the medical pump.

A drug delivery device, in the form of an injector, may include one of a number of systems for limiting the delivery of a medical fluid or drug product in case of movement of (e.g., removal of) the injector relative to the patient as determined by a proximity sensor. The drug delivery system may in the alternative or in addition include systems for indicating the amount of medical fluid or drug product delivered (or not delivered) in case of movement of (e.g., removal of) the injector relative to the patient as determined by the proximity sensor. The injector may be, for example, an on-body injector or an hand-held autoinjector.

A two-part bioactive agent delivery system, the system including a disposable part comprising an agent reservoir, a bolus chamber, the volume of the bolus chamber being less than the volume of the agent reservoir, an agent outlet, and a valve having a first position communicating the agent reservoir with the bolus chamber and a second position communicating the bolus chamber with the outlet; and a reusable part including a valve driver, a power source and control electronics, the control electronics being adapted to control the valve driver to actuate the valve to deliver bioactive agent from the agent reservoir to the agent outlet; the system further having a spring extending between the agent reservoir piston and a surface of the reusable part or of the disposable part to pressurize the agent reservoir when the spring is compressed and the agent reservoir contains a quantity of bioactive agent.

An IV flow rate regulator for precision dosage of medical liquids including a first part, a second part with an integrated outlet tubular connector and a mating attachment part with an integrated inlet tubular connector, coupled to one another in a rotatable manner with a first elastic gasket in a depression in the base wall of the second part, a second elastic gasket in a depression in the base wall of the mating attachment part, a dosing passage groove provided between the first and second gaskets, the dosing groove opening progressively the communication between the inlet tubular connector and the outlet tubular connector by rotation of the first and second parts. Also provided is a method for the fabrication of the IV flow regulator.

The present embodiments provide apparatus and methods suitable for delivering a therapeutic agent to a target site. The apparatus generally comprises at least one container for holding a therapeutic agent, and a pressure source for facilitating delivery of the therapeutic agent. In one embodiment, the pressure source may be placed in selective fluid communication with a proximal region of the container and fluid from the pressure source may flow through at least a portion of the container to urge the therapeutic agent through container towards the target site. In an alternative embodiment, the container and the pressure source may be coupled to first and second inlet ports of a connecting member, respectively, such that the therapeutic agent flows through an outlet port of the connecting member and towards the target site.

There is provided an IV flow regulator including a first part integrated with a flow control slit, the flow control slit being along a fluid path; a second part integrated with a central stem, the central stem including a spiral surface configured to contact the flow control slit, an area of contact defined by the spiral surface and the flow control slit being shaped substantially like an orifice to enable flow along the fluid path; and a dead space chamfer included in the second part at a portion of the fluid path subsequent to the area of contact.

Analyte sensing and response systems include a sensor detecting one or more analytes in a medium. The sensor uses decoupled transmit and receive elements or antennas to transmit a signal into the medium, and receive a response to the transmitted signal. An action that is based on the detection of the analyte is generated which can directly or indirectly affect the detected analyte in the medium. The action is automatically performed. The action can be increasing or decreasing flow from a source of the analyte, or of a chemical compound interacting with the analyte. An example of the action is controlling an insulin pump, where the analyte is glucose.

A device, system and method are provided for controlling the rate of infusion of fluids during infusion therapy using non-electric infusion devices. Rotation of a flow regulator dial causes an orifice connected to the inlet to modify its position relative to a particular one or more orifices or groove portions, the characteristics of which provide a certain flow rate characteristic. The flow regulator allows for the infusion pump to infuse at a rate that may be varied during use by the user. Additionally, the flow regulator is made from a material selected to operate under a wide range of pressures, from 5-40 PSI, making the flow regulator compatible with pressurized devices, such as, a non-electric pump.
