Abstract: An intravenous injection site having a split septum assembly interfit with the site for the intravenous administration of fluids to a patient. The split septum assembly has a resilient and compressible split septum having an axially-formed slit for receipt of a blunt cannula, needle, or other medical device through said slit, a septum holder for receipt of the split septum, and a septum housing for receipt of the combined septum holder and split septum. The septum includes a body and a flange extending radially from the body. A projection extends from the flange. The septum is mounted within the septum holder, and the septum holder is mounted within the septum housing to provide axial compression of the flange. This axial compression presents a double hermetic seal that significantly minimizes or prevents proximal leakage of fluid through the slit or around the septum holder when the cannula is removed.

Abstract: An anchoring device for securing a catheter to a patient includes a platform and a retaining strap. The platform includes a plurality of connectors extending outwardly from a base, each of the connectors including a head at a distal end of a post. The retaining strap cooperates with the platform to define a catheter-receiving passageway designed to receive a portion of the catheter. The retaining strap may include a first end including a first pull tab and a second pull tab, a second end including a third pull tab and a fourth pull tab, and a stretch portion between the first end and the second end. The retaining strap may also include a plurality of attachment locations, each of the attachment locations including a through-hole designed to receive the head of one of the plurality of connectors.

Abstract: An intravascular valve component broadly includes a valve case and a flexible pressure-actuated flow control valve. The valve case includes attached proximal and distal case portions that present respective spaced apart fluid ports and a fluid passageway extending between the ports. The flexible pressure-actuated flow control valve is disposed within the fluid passageway and includes a slitted central valve wall and an annular flange surrounding the central valve wall. The annular flange includes a radially-extending flange wall and a projection extending axially from the flange wall, with the projection engaging one of the case portions to restrict radial movement of the flow control valve relative to the valve case.

The flexible pressure-actuated flow control valve is disposed within the fluid passageway and includes a slitted central valve wall. The proximal case portion includes an axially-extending boss that projects distally, with a portion of a distal end of the boss contacting the flow control valve. The valve permits fluid flowing in a distal direction to pass through the slit. Fluid flowing in a proximal direction, however, causes the valve to compresses against the boss and the slit to close, thus restricting fluid flow in a proximal direction.

Abstract: An anchoring device for securing a catheter to a patient includes a platform and a restraining strap. The platform includes a plurality of connectors extending outwardly from a base, each of the connectors including a head at a distal end of a post. The retaining strap cooperates with the platform to define a catheter-receiving passageway designed to receive a portion of the catheter. The restraining strap may include a first end including a first pull tab and a second pull tab, a second end including a third pull tab and a fourth pull tab, and a stretch portion between the first end and the second end.

Abstract: An intravenous catheter anchoring assembly is disclosed and includes a patient-contacting membrane, a platform, and a retaining strap for securing a catheter or tubing of an administration set to a patient. The strap is attached to the platform with adjustable pull-tabs that permit a variety of catheter shapes and sizes to be secured. The strap is also elastomeric so that the strap is stretchable and thereby grabs the secured catheter. The strap and platform further define a plurality of passageways that permit the catheter to be secured in a plurality of non-aligned directions.

Abstract: An intravascular valve assembly having a valve case and a flexible pressure- actuated flow control valve. The valve case includes attached proximal and distal case portions that present respective spaced apart fluid ports and a fluid passageway extending between the ports. The flexible pressure-actuated flow control valve is disposed within the fluid passageway and includes a slitted central valve wall. The proximal case portion includes an axially-extending boss that projects distally, with a portion of a distal end of the boss contacting the flow control valve. The valve permits fluid flowing in a distal direction to pass through the slit. Fluid flowing in a proximal direction, however, causes the valve to compresses against the boss and the slit to close, thus restricting fluid flow in a proximal direction.

Abstract: An injection site (12) for infusion of parenteral fluids has a pressure-actuated valve (20) and a split septum unit (24), which prevent reflux of blood into the assembly (10). The septum unit (24) includes a resilient split septum body (64) precompressed so that the septum body (64) is caused to protrude proximally (78) upon insertion of a cannula (16). Consequently, upon removal of the cannula (16), there is essentially no “drumming” or creation of friction-induced negative pressures sufficient to generate blood reflux. The preloaded septum body (64) also has its proximal surface (74) essentially flush and coplanar with the adjacent proximal end (66b) of the tubular septum holder (66) to enhance the cleanliness of the unit (24).

Abstract: A catheter anchoring assembly includes a permeable adhesive strip, a platform for securing the catheter, and a flowable adhesive layer. The flowable adhesive layer adhesively secures the platform to the adhesive strip. The flowable adhesive is applied to one side of the strip with a skin-contacting adhesive on the opposite side of the strip. The flowable adhesive layer and strip are configured so that the flowable adhesive is spaced from the skin-contacting adhesive or, at the very least, is prevented from penetrating the skin-contacting adhesive. The flowable adhesive layer and strip also permit the assembly to be very flexible and, thus, comfortable for a patient to wear.
