Abstract
The invention relates to a needle stick guard for an anti-needle-stick puncturing kit for positioning a catheter according to the Seldinger technique, including a rocker having a journal so as to enable same to rotate about an axis, and an outer tip for locking the needle stick guard together with a base of another element of the puncturing kit. The rocker comprises three positions: a position in which it is locked together with another element of the puncturing kit; a position in which it is unlocked from the other element of the puncturing kit; and a protection position for trapping a sharp end of a needle in the guard.
Core Innovation
The invention relates to a needle stick guard for an anti-needle-stick puncturing kit for installing a catheter by the Seldinger method. The needle stick guard includes a rocker rotatable about an axis and an external tip configured for locking the needle stick guard together with a base of another element of the puncturing kit. The guard is provided to operate in a locking position, an unlocking position, and a protection position.
In the locking position, the external tip locks the needle stick guard together with the base of the other element of the puncturing kit. In the unlocking position, the external tip releases the needle stick guard from the other element of the puncturing kit. In the protection position, the sharp end of the needle is trapped by the body of the rocker.
The guard body includes a proximal hole and a distal hole for inserting a tube of a needle and for inserting a spiral guide between the proximal and distal holes. A slot receives the rocker, and a housing on the periphery of the slot receives the bearing of the rocker. The rocker has a spur within the body for controlling the position of the rocker with respect to an outer diameter of the tube of the needle and/or the spiral guide, where the locking, unlocking, and protection positions are obtained based on whether the spur rests on the tube of the needle, on the spiral guide, or on neither.
The puncturing kit further includes an immobilization element with a base and a ridge engagable by an external tip to temporarily immobilize the needle stick guard near a skin catheterization point. The immobilization element includes a hinged longitudinal element movable to a distal skin-contacting position, and the kit includes connector architecture including a guard housing and a needle housing that receive, mount, and facilitate handling of the needle, with the guard housing configured to block the rocker in the locking position.
Claims Coverage
The independent claim provides a needle stick guard for an anti-needle-stick puncturing kit for catheter installation by the Seldinger method, including three rocker positions and a spur that controls rocker position relative to the outer diameter of the tube of the needle and/or the spiral guide. The claim further specifies structural features of the body and its holes, slot, and rocker bearing housing, and defines how each rocker position is obtained based on where the spur rests. Additional dependent refinements add kit-level immobilization and connector features.
Rocker-based three-position needle stick guard for Seldinger catheter installation
A needle stick guard for an anti-needle-stick puncturing kit for installing a catheter by the Seldinger method, comprising a rocker having a bearing for rotation about an axis and an external tip for locking the needle stick guard together with a base of another element of the puncturing kit, where the rocker has a locking position, an unlocking position, and a protection position.
Spur-controlled rocker positioning relative to needle tube and spiral guide
The rocker has a spur within the body for controlling the position of the rocker with respect to an outer diameter of the tube of the needle and/or of the spiral guide, where the locking position is obtained when the spur rests on the tube of the needle, the unlocking position is obtained when the spur rests on the spiral guide, and the protection position is obtained when the spur rests on neither.
Body with proximal and distal holes for needle tube and spiral guide and rocker receiving structures
A body comprising a proximal hole and a distal hole for inserting a tube of a needle and inserting a spiral guide between the proximal and distal holes, a slot for receiving the rocker, and a housing on the periphery of the slot for receiving the bearing of the rocker.
Overall, the claim coverage centers on a rocker that moves among locking, unlocking, and protection positions, and a spur that selects those positions based on whether it rests on the needle tube, the spiral guide, or neither, with defined structural integration of the body holes, rocker slot, and bearing housing.
Stated Advantages
Needle sharp end trapping in a protection position by the body of the rocker.
Locking and unlocking of the needle stick guard together with and from the base of another element of the puncturing kit using the external tip.
Temporarily immobilizing the needle stick guard near a skin catheterization point using the immobilization element.
Blocking the rocker in the locking position via a recess in the guard housing when the needle stick guard is housed in the guard housing.
Documented Applications
Installing a catheter by the Seldinger method using an anti-needle-stick puncturing kit that includes the described needle stick guard.
Temporarily immobilizing the needle stick guard near a skin catheterization point on a living being during catheter installation by the Seldinger method.
Handling catheter installation components through connector architecture including a guard housing receiving a distal portion of the needle stick guard and a needle housing receiving a base of the needle.
