Safety needle system operable with a medical device
First Claim
1. A safety needle system operable with a medical device, comprising:
- a housing including a needle mount;
a needle having a distal end insertable through the medical device and a proximal end coupled to the needle mount;
a sheath telescopically engaged with the housing and circumferentially surrounding at least a portion of the needle, wherein the sheath operates in;
a retracted position, wherein the sheath exposes the distal end of the needle; and
an extended position, wherein the sheath substantially surrounds the distal end of the needle;
wherein the sheath is coupleable to the medical device such that removal of the needle from the medical device draws the sheath over the needle, thereby transitioning the sheath from the retracted position to the extended position; and
a slider, longitudinally engaged with at least one of the housing, sheath, and needle and including a restraint that selectively engages the sheath, wherein;
the restraint is engaged with the sheath in the retracted position, thereby reinforcing coupling of the sheath to the medical device in the retracted position; and
the restraint is disengaged from the sheath in the extended position, thereby weakening the coupling of the sheath to the medical device in the extended position.

Abstract
A safety needle system operable with a medical device includes: a housing with a needle mount having a needle; and a sheath telescopically engaged with the housing and surrounding the needle such that the sheath operates in a retracted position, in which the sheath exposes the needle, and an extended position, in which the sheath surrounds the needle. The sheath is coupleable to the medical device such that removal of the needle from the medical device draws the sheath over the needle, transitioning the sheath from the retracted position to the extended position. In one embodiment, the system includes a slider engaged with the sheath and/or housing and including a restraint that engages and disengages the sheath to respectively reinforce and weaken the coupling of the sheath and medical device. In another embodiment, the sheath includes a longitudinal track that slidingly engages a setting of the housing between sheath positions.

34. A safety needle system operable with a medical device, comprising:
-
a housing including a needle mount coupled to a setting that approximately axially centers the needle mount within the housing; a needle having a distal end insertable through the medical device and a proximal end coupled to the needle mount; a sheath telescopically engaged with the housing and having a distal wall defining a needle aperture and a longitudinal track that is substantially parallel to a longitudinal axis of the sheath and slidingly engaged with the setting of the housing, wherein the sheath operates in; a retracted position, wherein the sheath exposes the distal end of the needle; and an extended position, wherein the sheath substantially surrounds the distal end of the needle; wherein the sheath is coupleable to the medical device such that removal of the needle from the medical device draws the sheath over the needle, thereby transitioning the sheath from the retracted position to the extended position; and a locking mechanism configured to about a proximal portion of the sheath against a stop in the extended configuration, thereby locking the sheath in the extended configuration. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 55, 56)

51. A safety needle system operable with a vascular delivery system adapted to be placed about a catheter insertion site on a patient, wherein the vascular delivery system includes a frame with a catheter hub providing a first anchoring point on the patient, a stabilization hub providing a second anchoring point on the patient, and at least one lateral member extending between the catheter hub and stabilization hub, wherein the first and second anchoring points are distributed around the insertion site to anchor the frame to the patient, thereby stabilizing the catheter, the safety needle system comprising:
-
a housing including a needle mount; a needle having a distal end insertable through the catheter hub and a proximal end coupled to the needle mount; a sheath telescopically engaged with the housing and circumferentially surrounding at least a portion of the needle, wherein the sheath operates in; a retracted position, wherein the sheath exposes the distal end of the needle; and an extended position, wherein the sheath substantially surrounds the distal end of the needle; wherein the sheath is coupleable to the catheter hub such that removal of the needle from the medical device draws the sheath over the needle, thereby transitioning the sheath from the retracted position to the extended position; and a slider, longitudinally engaged with at least one of the housing, sheath, and needle and including a restraint that selectively couples to the sheath, wherein; when the restraint is coupled to the sheath, the restraint reinforces the coupling of the sheath to the catheter hub; and when the restraint is uncoupled from the sheath, the restraint weakens the coupling of the sheath to the catheter hub. - View Dependent Claims (57, 58)
