A catheter insertion device () includes a housing () with a base (), a catheter (), an introducer needle () and an actuator () mounted within the housing. The catheter () and needle () are coupled to the actuator () and movable between a first position where the catheter and needle are retracted within the housing and a second position where the catheter and needle extend from the housing, and where the needle retracts into the actuator when the catheter and needle reach the second position. The actuator () has a detent () that engages a first recess () to require a predetermined force to depress the actuator () which is greater than the force necessary to slide the actuator () to the second position where the detent () engages a second recess () in the housing () to hold the actuator in the deployed position.

Catheter insertion device

An infusion set is disclosed that includes an inserter including an inserter housing having at least one flexible arm for holding an infusion set in a single axial position prior to insertion of at least a portion of a cannula of the infusion set, the inserter housing having a surface for contacting the patient's skin. The inserter also includes a movable plunger disposed within the inserter housing for releasing the infusion set from the inserter housing, impacting the infusion set, and imparting momentum to the infusion set to insert the cannula into the patient's skin. The inserter additionally includes a biasing element biasing the plunger toward the activated position.

Perpendicular infusion set and disposable inserter

An inserter for inserting a needle or cannula of an infusion set comprises a fixed inserter member and a movable inserter member movably connected to said fixed inserter member and adapted to receive the infusion set. The movable inserter member is movable from a first position to a second position to expose the needle or cannula. The movable inserter member is locked to the fixed inserter member in the first position to prevent accidentally exposing the needle or cannula.

Angled inserter for drug infusion

A method of securing an infusion set to a skin surface, comprising the steps of placing a needle or cannula of the infusion set in the skin surface, and controlling a minimum bend radius of the placed needle or cannula to resist deformation and fracture thereof.

An insulin infusion device (A) is disclosed. The device includes a body (A), cannula () housed in the body (A), a cannula insertion device () and a cannula retraction device (). When the cannula insertion device is activated, the cannula () extends at least partly out of the body (A) and into an infusion site and when the cannula retraction device is activated after the cannula insertion device has been activated, the cannula () retracts into the body (A).

Cannula insertion and retraction device for infusion device

A fluid infusion device is provided with a cannula spring which functions as an introducer needle, a retraction return spring, and a fluid path. A hollow cannula tubing is wound, bent and sharpened into a shape which allows it to operate as an introducer needle, retraction spring and fluid path in an infusion device. A button is used to insert the introducer needle portion of the cannula spring and a soft catheter, and once the introducer needle portion and catheter have been fully inserted, an engagement between the button and post of the base of the infusion device releases the cannula spring such that the introducer needle portion of the cannula spring automatically retracts, leaving the catheter in the body. An end of the introducer needle portion of the cannula spring remains in fluid communication with the catheter in the body to provide an uninterrupted fluid path.

Fluid infusion device

An infusion set adapted to be secured to a skin surface includes a fixed base member and a movable slide member. The fixed base member is connectable to the skin surface. The movable slide member has a needle or cannula connected thereto and is movable relative to the fixed base member. The movable slide member is movable from a first position in which the needle or cannula is not exposed externally of the fixed base member to a second position in which the needle or cannula is exposed externally of the fixed base member. A hub is fixedly connected to the movable member and has a slot extending rearwardly in a lower surface from a first end thereof. The needle or cannula is received in the slot. The movable slide member is locked to the fixed base member in the second position.
