Abstract
An infusion device system includes a base (12) for removably coupling to a delivery device, a needle hub (22) supporting an insertion needle (20) and a catheter (18) for delivering a substance to a patient. The infusion device includes a needle shield (24) for covering the insertion needle (20) after inserting the catheter (18) into the patient. The needle hub (22) includes a least one leg (70) extending from the needle shield (24) to stabilize the needle shield (24) and needle hub (12) relative to the base. In one embodiment, the legs (70) can include a latching tab (74) to couple to the needle hub (22) to resist separation of the needle hub from the base (12) until the legs are deflected outward to release the needle hub (22).
Claims20
An infusion device comprising;
- a base having a catheter and a coupling for connecting to a delivery device;
- a needle hub having an insertion needle coupled to said needle hub and extending into said catheter, said needle hub having a bottom end for contacting said base;
- and
- a needle shield received in said needle hub for sliding with respect to said needle hub from a first retracted position to an extended position to cover said insertion needle, said needle shield having a bottom end removably coupled to said coupling of said base, and at least one leg extending radially outward from said bottom end of said needle shield and having a distal end spaced radially outward from said needle hub a distance to stabilize said needle hub relative to said base.
An infusion device comprising:
- a base having a catheter and a coupling for connecting to a delivery device;
- a needle hub having an insertion needle with a proximal end coupled to said needle hub and a distal end extending through said catheter, said needle hub having a bottom end for contacting said base;
- and
- a needle shield received in said needle hub for sliding with respect to said needle hub from a first retracted position to an extended position to cover said insertion needle, said needle shield having a bottom end removably coupled to said coupling of said base, and at least one leg extending radially outward from said bottom end of said needle shield and coupled to said needle hub to resist sliding of said needle hub relative to said needle shield.
A needle hub assembly for an infusion device comprising:
- a needle hub hang an insertion needle with a proximal end coupled to said needle hub and a distal end adapter for extending through a catheter of said infusion device, said needle hub having an open bottom end configured for contacting a base of the infusion device;
- and
- a needle shield received in said needle hub for sliding with respect said needle hub from a first retracted position within said needle hub and a second extended position extending from said open bottom end of said needle hub, and at least one leg extending radially outward from said needle shield and contacting a bottom edge of said needle hub, said at least one leg having a length to contact the base of the infusion device to stabilize said needle shield relative to the base of the infusion device.
