A connector set includes a male connector; and a female connector. The male connector includes: a hollow rod-shaped flow path connection portion that defines a first flow path therein and that has a first axis as a center, and a lock protrusion that has an inner peripheral edge extending in a circumferential direction around the first axis. The female connector includes: a cap, a housing, and a valve body. The cap includes: a top wall, and a cylindrical outer peripheral wall extending from an outer peripheral edge of the top wall and that has a second axis as a center. The housing includes: a cylindrical wall, and an engagement protrusion protruding from an outer peripheral surface of the cylindrical wall so as to form a lower surface configured to engage with the lock protrusion to lock the male connector.

A medical device securement system is configured to secure medical devices such as catheters in place. The securement system includes an anchor pad that attaches to a patient's skin. A malleable support base is attached to an upper surface of the anchor pad. The support base has front and back inclined surfaces that are separated by an offset surface that extends generally normal to both of the inclined surfaces. A spot of adhesive is applied to one or more of the inclined surfaces. A catheter assembly includes a connector having a first connector portion with a diameter larger than an adjacent second structure. The catheter assembly is attached to the support base with the first connector portion engaged with and supported by the back inclined surface, and the second connector portion engaged with and supported by the front inclined surface.

A sterile solution product bag includes sterilization grade filter integrated directly into the product bag such that microbial and particulate matter filtration can be performed using the filter directly at the point of fill. The filter can include a hollow fiber filter membrane contained in a stem connected to a bladder of the product bag.

An infusion filter design combines a fluid infusion device and a blood filtration device that filter blood during a thrombolysis procedure while allowing for complete filter removal on procedure completion. In one embodiment, a wire comprises a proximal, non-infusible length that extends partially outside of the patient and within the vein. The wire further comprises an infusible length distally from the non-infusible length that is extends within the vein so as to be placed at the section of the vein requiring medication. The wire also comprises a distal filter component at a distal end of the wire that is employed to filter the blood in the event that during the period that clot is dissolved it migrates toward the central circulation.

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a single-use, aseptic disconnection functionality that substantially prevents fluid spillage when being disconnected. In some embodiments, the coupling portions cannot be reconnected to each other after being disconnected from each other.

A method for performing a medical procedure requiring effective, reliable and foolproof delivery of controlled amounts of a medical grade gas to a patient includes providing a compressed gas cylinder having a weight with medical grade gas sealed therein of at least twelve grams and not greater than fifty grams. The method also includes connecting the compressed gas cylinder to an integrated compressed gas unit including a regulator valve assembly positioned between an outlet port and an inlet port, wherein the regulator valve assembly includes a press button actuator and regulator adjustment dial. A flow control system is secured to the compressed gas unit and the medical grade gas is delivered in precisely controlled amounts by actuating the compressed gas unit and operating the flow control system to deliver the medical grade gas to vasculature of the patient.

A fluid mixing device for mixing a first injection fluid and a second injection fluid includes a first fluid inlet, a second fluid inlet, a mixing chamber in fluid communication with the first and second fluid inlets, and an outlet port in fluid communication with the mixing chamber. The first fluid inlet is configured to conduct the first injection fluid in a first direction and has a first redirecting surface. The second fluid inlet is configured to conduct the second injection fluid in a second direction along a different axis from the first direction and has a second redirecting surface. The mixing chamber is configured to mix the first injection fluid and the second fluid together. The mixture of the first injection fluid and the second injection fluid exits the fluid mixing device via the outlet port.
