A fluid transfer device or connection with a fluid transfer tip that has a tapered friction fitting for a corresponding hub. A lever member is pivotally mounted to move relative to the fluid transfer tip. A latch such as a screw thread is mounted on the lever member to engage the hub and provide a positive connection e.g., screw fit in addition to the friction fitting. The lever member may optionally be resiliently biased by a spring. The hub is disconnected from the tip by pivoting the lever member to release the positive connection with the hub and to subsequently release the hub from the friction fitting.

A luer adapter includes a body including an inner surface defining a lumen and first and second ends. Each end is adapted to connect to a medical device. An antimicrobial material is positioned at least on a portion of the inner surface. A barrier is positioned between the lumen and the antimicrobial material and permits the passage of the antimicrobial material therethrough upon exposure to moisture. The barrier may include hydrophilic material.

A connector includes a housing defining a male connector insertion section into which a male connector is inserted from the outside and an elastic valve body having a slit and blocking the male connector insertion section. The elastic valve body includes a top face having the slit and a bottom face located opposite to the top face. The housing includes a holding section having contact with the top face and the bottom face of the elastic valve body to hold the elastic valve body. The holding section surrounds the slit when the valve body is viewed from the top face. The diameter of a bottom face side holding section having contact with the bottom face is smaller than the diameter of a top face side holding section having contact with the top face.

A surgical utility connector is detectable by a surgical utility supplying device to indicate connection with the surgical utility supplying device. The surgical utility connector includes a first connecting region, a second connecting region, and a detection region between the first connecting region and the second connecting region. A utility channel may pass a utility from the surgical utility supplying device. The utility channel may extend through the first connecting region, the detection region, and the second connecting region. The surgical utility connector also may include a magnetic element disposed in the detection region and surrounding the utility channel. The magnetic element may have a field detectable by the surgical utility supplying device when the surgical utility connector is connected to the surgical utility supplying device.

A low profile adaptor is disclosed to reduce the length of a gastrostomy tube that has been inserted by means of conventional endoscopic procedures or with a replacement feeding tube inserted into the patient's stomach. The gastrostomy tube is cut to the appropriate length by the physician. The adaptor comprises a stem which is inserted into the open end of the gastrostomy tube. The valve assembly contains a seal that functions as a one-way valve to prevent reflux of gastric contents but permits the introduction of feeding solution into the feeding tube. A lock and key mechanism is incorporated into the hub of the gastrostomy tube to prevent disconnection of the feeding tube. A cover is placed over the opening of the adapter to prevent contamination of the lumen of the gastrostomy tube.

A catheter proximal section is preferably formed from a relatively soft part and a relatively rigid part, and includes a proximal terminal end that defines a perimeter of an opening into a lumen of the catheter. The proximal section may further include a feature for interlocking engagement with an accessory tool. An inner surface of each of the relatively soft and rigid parts may be located opposite one another, on either side of the catheter lumen. The relatively soft and rigid parts may be included in a sealing assembly that further includes an attachment feature for removable connection of the assembly to the proximal section catheter.

A tube connector includes a flexible member that engages an inserted length of tubing. The flexible member is configured to adhere to the tubing in the presence of an applied solvent, thereby forming a hermetic seal.

A tubing adapter for interconnection with a least one tubing section of a medical device, a dialysis fluid tubing system including such a tubing adapter, a medical device including such a dialysis fluid tubing system, and a method for avoiding a pressure within a dialysis fluid tubing system that is below a minimum pressure are described.

An adapter for a medical receptacle having an internally threaded skirt with an outside diameter and an inside diameter, and a post within the skirt, includes a proximal end portion having a threaded surface including at least one thread configured to threadingly engage a threaded interior of a skirt of a medical receptacle, and a distal end portion having a surface portion and a generally cylindrical recess. The proximal end portion includes a tapered recess defined by a wall, a chamfer, and a seat and the surface portion includes a gripping mechanism. A conduit is positioned between the tapered recess and the generally cylindrical recess such that the conduit is in fluid communication with both the recess and the generally cylindrical recess.

The male connector of the present disclosure allows for the flow of fluids therethrough and includes a movable blunt needle having a shoulder projecting radially outwards from the movable blunt needle. The male connector also includes an outer cylinder body formed around the movable blunt needle and disposed in coaxial alignment to the movable blunt needle, a blunt needle retainer which retains the movable blunt needle so that the movable blunt needle can move in an axial direction, and a valve which opens as a result of the movable blunt needle moving in the axial direction when the posterior end presses against the valve. This occurs when the movable blunt needle is inserted into a corresponding connection site, such as a female connector, and the shoulder presses against the connection site to force the movable blunt needle in the axial direction.
