An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.

A fluid delivery system and a fluid conduit assembly suitable for use with the system are disclosed herein. The system includes a fluid infusion pump and a fluid conduit assembly coupled to the pump to deliver medication fluid to a user. The fluid conduit assembly includes a structure defining a flow path for the medication fluid, and a gas trapping filter coupled to the structure and positioned in the flow path. The gas trapping filter functions to filter particulates from the medication fluid and retain gas bubbles from the medication fluid. The structure includes at least one retaining feature to inhibit movement of the gas trapping filter.

Provided is a fluid wicking tip. The fluid wicking tip includes a plurality of drip flanges arranged to wick fluid between narrow spaces defined between any two drip flanges. The narrow spaces are dimensioned to facilitate wicking by capillary action. Also provided is a syringe that includes the fluid wicking tip. Also provided is a modular syringe system that includes a syringe and a sleeve configured to be slidably disposed over the syringe.

An infusion tube system and a method for manufacture are provided. An infusion tube system including an infusion tube and a connector attached to the infusion tube at an end of the infusion tube is disclosed. The connector has a proximal end and includes a connector body extending from a distal end to a proximal end along a center axis and defining a cavity. The connector body includes an end wall with an inner surface, and at least one vent opening, and a sidewall extending from the end wall along the center axis with an inner and outer surface. The connector includes a membrane covering the at least one vent opening, the membrane being welded to the inner surface of the end wall along at least one welding seam including a first welding seam such that the membrane covers and seals the at least one vent opening.

An improved oscillating positive expiratory pressure (“OPEP”) device, for respiratory therapy having a self sterilizing flow valve capable of insertion into the curved OPEP body without tools or aids. The flow valve is also tear resistant and incorporates a flared reinforced proximal end. To maximize the benefit to patients, the adjustable therapy selector is constrained from withdrawal and is dimensioned to accept commercially available, standardized respiratory fittings adaptors, mouthpieces and “Tees” that are capable of connection to multiple respiratory therapy devices or medicated aerosol delivery units. The aesthetics have been altered by the addition of an arced handle.

A fluid conduit assembly for delivery of a medication fluid, and an associated fluid delivery system, are disclosed here. The fluid conduit assembly includes a trapping chamber having an interior volume to receive the medication fluid. The fluid conduit assembly also includes an inlet in fluid communication with the interior volume, a first outlet arrangement for the trapping chamber, and a second outlet arrangement for the trapping chamber. The first outlet arrangement accommodates flow of liquid from the interior volume, while inhibiting flow of gas from the interior volume. The second outlet arrangement accommodates flow of gas from the interior volume, while inhibiting flow of liquid from the interior volume.

Systems for managing pressure in a fluid reservoir chamber of a fluid infusion device are provided. For example, a fluid infusion device is provided. The fluid infusion device comprises a housing defining a reservoir chamber for receiving a fluid reservoir. The fluid infusion device also comprises a drive system contained within the housing for dispensing fluid from the fluid reservoir. The fluid infusion device comprises a pressure management system at least partially defined in the reservoir chamber to manage air pressure in the reservoir chamber.

This invention concerns improved single use caps or covers for vascular access devices such as needlefree connectors that are used, for example, in intravenous administration sets and extension sets. Removal of a single use cap or cover according to the invention from a vascular access device destroys the cap such that it cannot be reused. Such single use caps and covers will help ensure compliance with infection prevention protocols in healthcare settings, which will assist in reducing the incidence of healthcare-associated infections (HAIs), particularly catheter-related blood stream infections. Assemblies and kits its including such caps and covers, for example, IV administration and extension sets that include one or more needlefree connectors, as well as methods for using such caps and covers, are also described.

A valve for use in manufacturing of implantable medical devices is insertable into a bore of the medical device during a manufacturing process. The valve is configured to remain closed while the pressure differential between an internal volume of the implantable medical device and a surrounding environment is below a particular threshold and to open when the threshold is reached, thereby allowing air or other fluids to escape from the internal volume into the surrounding environment. The valves are particularly useful during certain types of coating processes that must be performed at or near vacuum and provide an effective way to prevent ingress of coating material into the internal volume of the implantable medical device.

A urinary catheter cap includes a main body that includes a urine introduction passage including a connection hole configured to be connected to a urinary catheter and a drain hole for draining urine, a lid portion that has a tubularly formed portion having a first end portion at the drain hole side and a second end portion at an opposite side and opens and closes the drain hole, a partition portion that divides the tubular portion of the lid portion into a plurality of spaces, and a hydrophobic film that is formed such that the hydrophobic film blocks at least two or more of the spaces at the second end portion of the lid portion. The partition portion may include a partitioning plate that is installed between a plurality of locations of an inner circumferential portion of the tubular portion of the lid portion.
