A medical connector for use in a fluid pathway includes a substantially transparent housing having a proximal end with a proximal opening and a distal end with a distal opening, and a cavity extending therebetween. The connector provides a substantially visible fluid flow path extending through a substantial portion of the connector.

An intermittent, injection port assembly includes a flexible valve member of the type which is laterally deflected when moved from a closed position to an open position. A high flow non-tortuous flow passage is provided through the injection port assembly by a plurality of lateral passages bypassing a base which supports the flexible valve member.

Some embodiments relate to a luer connector comprising a housing having a hollow bore therethrough, a first end, and a second end, a male luer tip supported by the housing configured to rotate with respect to the housing, the luer tip having a first open end and a passageway through the luer tip in fluid communication with the first open end, and a substantially rigid internal member extending into the passageway of the luer tip toward the first open end of the luer tip. In some embodiments, at least one of the luer tip and the internal member can be axially moveable between a first closed position and a second open position relative to the other of the luer tip and the internal member. Further, the luer tip and the internal member can cooperate such that rotation of the luer tip in a first direction relative to the housing increases an axial displacement between the first open end of the luer tip and an end portion of the internal member.

Some embodiments disclosed herein relate to a medical connector having a backflow resistance module configured to prevent fluid from being drawn into the connector when a backflow inducing event occurs. In some embodiments, the backflow resistance module can include a variable-volume chamber configured to change in volume in response to a backflow-inducing event and a check valve configured to resist backflow. In some embodiments, the medical connector can include a fluid diverter configured to direct fluid flowing through the medical connector into the variable volume chamber to prevent fluid stagnation therein. In some embodiments, the medical connector includes a body member, a base member, a seal member, a support member, and a valve member.

A gastrointestinal balloon system includes a gastrointestinal balloon and a check valve located within the gastrointestinal balloon. The check valve is configured to allow fluid flow into and out of the gastrointestinal balloon. The check valve includes a string coupled to the check valve, the string having a loop on a proximal end and a catheter having a lumen. The lumen is configured to receive a grasping tool. The grasping tool extends out a distal end of the catheter for grabbing the loop to align the catheter with the check valve. Also, a check valve, two-wat valve, and method of using the same in a gastrointestinal balloon.

Pre-filled syringes, pharmaceutical compositions, and kits and methods relating to same allow for emergency administration of one or more drugs from prefilled glass syringes to a patient via a needleless connector. In preferred embodiments, the prefilled glass syringe has a drug volume of at least 5 mL, has a Luer-lock, and has a syringe tip with an internal channel that has a diameter of about 1.7 mm. Such syringes advantageously allow storage of emergency drugs without leaching of plastic materials and degradation, and substantially improve the safety profile where the syringe is attached to an IV line via a needleless connector.

A valve connector for infusion medical lines includes an outer tubular body, an inner hollow spike and an intermediate sealing member formed by an elastic hollow element including a head with a pre-slit normally closed. The elastic hollow element has a base part substantially generally barrel-shaped and a wall having a differentiated radial thickness.

Inside a connector body (112, 114; 300) of a medical connector providing a fluid flow conduit, a one-way valve (118) is fitted directly into one end of a stop valve (116) in a manner providing a fluid tight seal between these valves. The stop valve (116) prevents fluid flowing out of the end (111; 311) of the connector body (112, 114; 300) unless a complementary end of a separate device (not shown), typically a Luer lock connector, engages the end of the connector body and opens the stop valve (116). To facilitate manufacture and assembly, the one-way valve (118) and the stop valve (116) can be formed as parts of a single piece of elastomeric material, the parts being hingedly connected so that the one-way valve part (118) can be folded over to be fitted directly into the end of the stop valve part (116). A further possibility, also applicable when only a stop valve (116) is provided, is that the connector body (300) may be formed in one piece with a folding, snap fit closure (312).

A body-fluid-and-medication leak-proof and closed medical connector has a first connecting assembly and a second connecting assembly. The first connecting assembly has a first sleeve and a first resilient valve. The first resilient valve tends to seal a first opening of the first sleeve. The second connecting assembly has a second sleeve and a second resilient valve. The second resilient valve tends to seal a second opening of the second sleeve. The two resilient valves can avoid leakage of the medication remaining in an injector and a vial, or remaining in a fluid infusion tube and a catheter. The two resilient valves also can seal in two directions to avoid leakage during connecting or separating the two connecting assemblies after supplying medication. Therefore, the transfer of the medication is more hygienic and safe, and the waste of medical resources is effectively reduced.

A connector for connecting a first medical line to a second medical line is disclosed. This connector comprises an insertion shaft (12) having a flow channel that is intended to be brought into fluid communication with a lumen of a first medical line (3); a collar (10) that circumferentially extends around the insertion shaft (12), wherein the collar (10) comprises a first thread (100) on an inner side that faces the insertion shaft (12); and an elastic member (14) that is placed between the insertion shaft (12) and the collar (10), wherein the elastic member (14) comprises an abutment portion (141) abutting a surface of the insertion shaft (12) and being displaceable relative to the surface of the insertion shaft (12). The collar (10) is radially movable around the insertion shaft (12) and the elastic member (14) comprises a thread portion (142) having a second thread that engages the first thread (100) of the collar (10) such that a rotational movement of the collar (10) around the insertion shaft (12) results in a lateral displacement of the elastic member (14) along the surface of the insertion shaft (12). Furthermore, a method for operating such a connector is disclosed. Additionally, a connector assembly comprising such a connector is disclosed.
