A system for measuring drip rate may include a drip chamber device comprising an elongated body including an inner surface defining a chamber, and a drip rate measurement device. The drip chamber may be fluidly coupled to a container containing an IV fluid configured to drip droplets of the IV fluid into the chamber. The drip rate measurement device may include a housing configured to be mounted to the elongated body of the drip chamber, and a load cell transducer mounted in the elongated body and extending into the chamber. The load cell transducer may be configured to measure a weight of the droplets of the IV fluid and convert the weight into an electrical signal. The drip rate measurement device may further include a controller electrically coupled to the load cell transducer to process the electrical signal and output at least one parameter associated with the IV fluid.

A piercing part for a medical infusion system includes a housing with a piercing mandrel, a fluid channel and a ventilation channel with a first channel portion extending at least substantially parallel to the fluid channel and with a second channel portion diverted towards an outside of the housing and to which an air filter element and a fluid shut-off member are assigned. A drip chamber can include a piercing part. The piercing part can be produced by an injection molding tool. The second channel portion in the housing is oriented parallel to the first channel portion and open towards an inside of the housing. An open region of the channel portion is closed by a separately produced closure part. The piercing part can be used with a medical infusion system.

The present invention provides infusion devices, such as intravascular (IV) devices, comprising a hydrophilic sintered porous plastic filter or a hydrophilic porous fiber filter which are effective at stopping or greatly reducing transmission of air through the filter.

Disclosed devices for injection of medicament to a subject can include a hand-held unit, at least one control unit, and one or more medicament chambers fluidly coupled to the control unit. The hand-held unit having a head portion and a body portion, the head portion comprising at least one needle and a movable head, the movable head being axially movable relative to the body portion between an extended position and a retracted position. The control unit being fluidly coupled to the hand-held unit and having a pump having a dosing chamber.

A flow control device includes an upper housing, a lower housing, a chamber interposed between and defined by the upper and lower housings, and a valve member. The upper housing includes a primary inlet having an internal surface defining a cavity and a secondary inlet. The lower housing defines an outlet of the flow control device. The chamber fluidly connects the primary and secondary inlets with the outlet. A valve member is reciprocally disposed at least partially in the cavity and partially in the chamber to (i) selectively permit fluid flow in the primary inlet in a first direction when a fluid level in the chamber is below a predetermined level, and (ii) prevent fluid backflow in a second direction opposite to the first direction when the fluid level in the chamber is above the predetermined level.

Apparatus for preventing accidental separation of an IV tube or spike from an IV medication bag or bottle, thereby preventing spills or leakage of hazardous medication and/or biohazards. The apparatus includes a top clamp to attach around the stem of a medication bag or around the neck of a bottle, a bottom clamp to attach around a drip chamber of an IV tube, and a connecting portion connected to both the top clamp and the bottom clamp, the connecting portion ensuring that the top clamp cannot be pulled away from the bottom clamp. The top clamp can be removably attachable so as to enable clamping and unclam ping at the bag stem or bottle neck for situations requiring sequential bag changes, in the case of multiple blood products, or multiple IV bottles. Or, the top clamp can be permanently attachable, which is useful in the context of chemotherapy or immune therapy.

An intravenous infusion detection device is provided in the invention. The intravenous infusion detection device includes a radar device, a digital signal processing (DSP) device and a controller. The radar device includes a plurality of transmission antennas and a plurality of receiving antennas. The transmission antennas are configured to transmit a plurality of radar signals and the receiving antennas are configured to receive a plurality of reflection signals corresponding to the radar signals. The DSP device transforms the plurality of reflection signals received from the plurality of receiving antennas into a plurality of one-dimensional (1D) waveform diagrams, transforms the plurality of 1D waveform diagrams into a three-dimensional (3D) waveform diagram, and obtains a drip level of a drip bag according to the 3D waveform diagram. The controller obtains the drip level of the drip bag from the DSP device and calculates the flow rate of the intravenous infusion.

A drip chamber is provided that includes a hollow body and a nucleation column extending into the interior of the hollow body or formed on the inner surface of a drip chamber sidewall. The nucleation column can be formed with, or treated by a treatment to include, microfeatures or other surface properties that provide nucleation sites for the nucleation and amalgamation of microbubbles. The drip chamber can include a bubble catcher in the bottom of the hollow body and the nucleation column can extend from the bubble catcher into the interior of the hollow body. Methods of making such drip chambers are also provided.

Disclosed a monitoring device comprising housing configured to attach to a user or to a user aid item, at least one attachment assembly provided in the housing and configured to attach to a respective at least one removable sensor module, electric circuitries or contacts mounted in or on the housing and configured to provide an electrical interface between the at least one removable sensor module and one or more external devices, and inlet and outlet fasteners provide in the housing and configured to receive and hold respective fluid supply and fluid dispensing lines. The fluid supply and fluid dispensing lines can be connected to the at least one removable sensor module attached to the at least attachment assembly for dispensing fluid media therethrough. The at least one sensor module can be configured to measure at least one property or condition of the fluid media, and the electrical circuitry can be configured to communicate measurement data or signals generated by the at least one sensor module to the one or more external devices.

A monitoring system for a gravity infusion IV tubing includes a drip chamber having an inlet configured to receive fluid from a fluid source. The drip chamber also has an outlet configured to deliver fluid towards a patient. The system includes a pressure sensor pneumatically coupled with the drip chamber. The pressure sensor is configured to measure the pressure inside the drip chamber. A controller is configured to receive pressure measurements from the pressure sensor and to use the pressure measurements to count a number of drops entering the drip chamber from the fluid source.
