An exemplary pharmaceutical compounding system and device for mixing materials from at least two distinct material sources can include a valve including a valve housing and a valve structure located within the valve housing. The valve structure can be configured to permit fluid to flow through the valve when in an open position, and can include a gravity wall wherein, when the valve structure is in the open position, fluid moving through the valve structure moves upward against a force of gravity when travelling through the valve and traversing the gravity wall.

A connector is connectable to a medical device that includes a female connector portion. The connector includes: a main body member including: a cylinder portion that is insertable into the female connector portion, and a lock portion configured to, upon insertion of the cylinder portion into the female connector portion, pass over part of the medical device and then move in a predetermined locking direction to lock the medical device; and a lock member that is movable with respect to the main body member. When the main body member is in a state in which the lock portion locks the medical device, the lock member is moveable to a lock position at which the lock member limits movement of the lock portion in a predetermined unlocking direction.

A valve assembly for a dental suction system. The valve assembly includes a valve body having an inlet, an outlet and a fluid flow path extending between the inlet and the outlet. The valve assembly also includes a valve plug positioned at least partially within the valve body and including a through-passage. The valve plug is rotatable relative to the valve body to selectively alter a flow of fluid along the fluid flow path. The fluid flow path exhibits a varied cross-sectional area along a length of the fluid flow path.

An aspiration system including a housing containing an aspiration pump, a chamber, a collection bag in fluid communication with the chamber, and a tubing assembly including a first tube portion connected to the chamber. The tubing assembly has a connector to split the first tube portion into a second and third tube portion, the second tube portion in fluid communication with a first catheter to aspirate particles through the first catheter and the third tube portion in fluid communication with a second catheter to aspirate particles through the second catheter.

The disclosure relates to a medical fluid coupling for connecting a fluid line to a connection section of a blood treatment apparatus or for connecting to a connecting adapter. The fluid coupling comprises at least one main body. The main body includes a first latching element with a first section. The first section is designed to be elastically bendable and/or elastically tiltable. The main body may optionally include a second latching element with a second section. At least one of the first latching element and the second latching element comprises a recess for receiving a protrusion of the connection section and/or a protrusion to reach into a recess of the blood treatment apparatus or of the connecting adapter.

A connection system for components through which a fluid is passed comprises an actuator and a main housing. The actuator has a cylindrical portion with an outer face. A handgrip is arranged at a first end of the cylindrical portion. In the region of a second end the cylindrical portion has a cavity, which is open towards the second end, and in the region of the second end there are arranged at least two gate-like passage openings for fluid connection. The main housing has a main body and at least two fluid passages arranged laterally on the main body. The main body has a cavity with an open first end, a base in the region of a second end, and at least two laterally arranged openings, which each produce a fluid connection to a corresponding one of the fluid passages. The cavity receives the cylindrical portion of the actuator rotatably through the open first end, and the inner diameter of the cavity corresponds to the outer diameter of the cylindrical portion of the actuator. The laterally arranged openings correspond to the passage openings of the actuator. A substantially cylindrical bearing pin is arranged on the base of the main body and a peripheral surface shaping is arranged in the region of the second end of the actuator, which shaping at least partially surrounds the bearing pin and thus forms a counter bearing for the second end of the actuator.

A liquid transfer device is described. The liquid transfer device comprising a vial adapter comprising a puncturing cannula for puncturing an injection vial stopper, an IV spike and a substitute IV port holder for receiving a substitute IV port, and a flow control member port. The IV spike, the substitute IV port holder and the puncturing cannula are in flow communication with the flow control member port. The liquid transfer device comprising a flow control member sealingly inserted in the flow control member port. Rotation of the flow control member between a plurality of positions controls flow communication of the liquid transfer device, the positions comprising a mixing position for enabling flow communication between the IV spike and the puncturing cannula; and an administering position for enabling flow communication between the IV spike and the substitute IV port holder.

Fluid flow control devices for medical use are disclosed. On one end, a fluid flow control device is configured to be attached to a manifold that is in-line with an infusion setup and the other end of the fluid flow control device is configured to be attached to a sampling or infusion device, such as a syringe. In one aspect, a fluid flow control device has an external casing and an internal casing which is configured to be movably housed within the external casing. The internal casing mates with a fluid outlet on the external casing and upon separating the internal and external casings a fluid flow path is established.

A pipe for fluid supply includes: a pipe configured integrally with an air feeding conduit and a pressure measurement conduit; inlets of the air feeding conduit and the pressure measurement conduit; outlets of the air feeding conduit and the pressure measurement conduit; and tube connection portions provided at the respective inlets in the pipe such that an angle between a vertical direction of the respective inlets and a vertical direction of each the respective outlets is 30 to 60.

A flush device including: a first housing provided with a first flow path; a second housing provided with a second flow path, the second housing being coupled to the first housing; a flow control device including a protrusion and a through hole connecting the first flow path to the second flow path in fluid communication; and an elastic member provided around the base of the flow control device to seal off a space between the first and the second flow paths. The elastic member is deformed to further connect the first and second flow paths in fluid communication. The first housing has an inner periphery provided with fitting receiving portions each being fitted to each of the fitting projections of the protrusion. According to this structure, the flush device can discharge a chemical liquid at a flow rate close to a defined amount.
