A precision roller clamp assembly for adjusting the fluid flow rate in a tube of an infusion set is provided. The roller clamp assembly includes a housing to receive the tube and a roller wheel moveably engaged with the housing. The housing includes a tube groove disposed in a guide wall, the tube groove dimensions configured to provide a precise fluid flow adjustment over a majority of the travel path of the roller wheel. A method of operating a precision roller clamp assembly is also provided.

A catheter assembly may include a catheter adapter, which may include a body and a nose extending distally from the body. The nose may be generally cylindrical. A strain relief rib may be disposed on the nose. The strain relief rib may be constructed of a flexible material. The catheter assembly may also include a needle secured within the catheter adapter and extending distally beyond the nose. The catheter assembly may further include a needle cover, which may be removably coupled to the nose of the catheter adapter. An inner surface of the needle cover may be smooth and may contact the strain relief rib.

Needle cover retention

A self-slitting open lumen cannula may be used with catheter adapters to reduce manufacturing complexity and costs, as well as improve the safety of the catheter adapters against fluid leakage. The open lumen cannula may also include one or more notches to facilitate flashback visualization. The catheter adapters may further include a catheter adapter body formed of a compliant material that houses one or more compression resistant septa with at least one lumen formed by the proximal end of the needle during a self-slitting process as the catheter adapter is assembled. The compression resistant septum may also be coupled to a compression cap that imparts a radial compression force on the one or more compression resistant septa such that the at least one lumen narrows and seals when the cannula is removed.

Anti-snagging components for use in infusion sets are provided. The anti-snagging component includes a sliding surface that guides an infusion set component past an obstruction when the infusion set is moved during manufacture or use. An anti-snagging structure may be integrally formed as a portion of an infusion set component or the anti-snagging structure may be a separate component that connects or attaches to an infusion set component. Some anti-snagging structures include a covering portion to cover a needleless connector and a tail portion to connect to a length of tubing. The covering portion may include an anti-microbial coating.

A device for delivering a medicament into a patient's body by injection into or through the patient's skin includes a body having a reservoir disposed therein for containing the medicament, an injection needle for penetrating the skin of the patient, the needle having a lumen and communicating with the reservoir, and a pressurizing system for pressurizing the reservoir. The device also includes indicator means visible outside the device for indicating that delivery of the medicament is substantially complete.

Self-injection device

The present invention extends to a design of a needle hub and an actuator of a catheter assembly that allows the needle hub and actuator to interlock within the catheter hub. This interlocking allows the needle hub to be inserted into the catheter hub thereby increasing the rigidity of the catheter assembly. The interlocking can be accomplished by forming channels in the proximal end of the actuator and corresponding protrusions from the distal end of the needle hub. In some embodiments, the channels and protrusions can be formed at the top and bottom of the catheter hub and needle hub respectively to thereby increase the vertical rigidity of the catheter assembly. The increase in vertical rigidity can prevent flexing of the catheter hub with respect to the needle shield when a downward force is applied to the catheter assembly such as is common during insertion of the needle.

A drug delivery device, including a body () having a reservoir () disposed therein for containing a medicament and an injection needle () for penetrating the skin of a patient, the needle () providing a path for the medicament between the reservoir () and the patient. The device also includes a rotor () rotatably disposed in the body () for activating the device upon rotation of the rotor (), a needle cover () for covering the injection needle, and a needle cover clip () disposed on the needle cover () to rotate from a first position preventing rotor rotation to a second position permitting rotor rotation.

A drug delivery device () includes a body () having a reservoir () disposed therein for containing a medicament and an injection needle () for penetrating the skin of a patient, the needle () providing a path for the medicament between the reservoir () and the patient. The device () also includes a plunger () movable within the body () for causing the medicament to be expelled from the reservoir (), and a biasing means () for biasing the plunger () toward the reservoir (), wherein in a pre-activated position, the biasing means () telescopes within itself, and upon activation, provides a force to the plunger () for expelling the medicament from the reservoir (). The biasing means () is preferably provided in the form of a conical spring having a variable pitch.

A septum is disclosed that can be utilized in a catheter assembly to selectively seal an opening in the catheter assembly. The septum has a tube portion and a plug portion. The plug portion has a slit extending through it. The septum can transition from a non-collapsed state to a collapsed state. When the septum is in a non-collapsed state, the plug portion is offset from the tube portion such that some of the length of the slit extends outward from the distal end of the tube portion. When the septum transitions to the collapsed state, the plug portion is moved inward into the internal cavity such that some of the length of the slit may or may not extend outward from the distal end of the tube portion.
