Abstract
Butterfly assemblies to deliver a fluid into a patient's anatomic space include a body and extensions. The body has an opening to receive a needle to penetrate into a patient's anatomic space, and the extensions are hinged to the body and movable between a closed, compact position and an expanded, open position without significant biasing forces tending to move the extensions into either position. Each extension has an outer periphery at least partially surrounding an interior surface having a locking structure to mate with the other extension and lock the extensions together in the closed, compact position.
Claims20
An assembly to deliver a fluid into a patient's anatomic space, the assembly comprising:
- a body having an opening to receive a needle to penetrate into a patient's anatomic space, and
- extensions hinged to the body and movable between a closed, compact position and an expanded, open position without any significant biasing force tending to force the extensions into either position, each extension having an outer periphery at least partially surrounding an interior surface having a locking structure to mate with the other extension and lock the extensions together in the closed, compact position.
An assembly to deliver a fluid into a patient's anatomic space, the assembly comprising:
- a needle to penetrate into a patient's anatomic space;
- a needle protector surrounding the needle;
- a body having a longitudinal axis and an opening to receive the needle;
- extensions hinged to the body and movable between a closed, compact position and an expanded, open position, each extension having an outer periphery at least partially surrounding an interior surface having a locking structure to mate with the other extension and lock the extensions together in the closed, compact position;
- and
- a recess disposed in at least one of the extensions to guide and maintain the needle protector in a substantially 90 degree orientation relative to the longitudinal axis of the body.
A method for delivering a fluid into a patient's anatomic space through a needle having a needle protector and being supported by a butterfly assembly having a base and a pair of wings extending from the base, with a guiding channel supporting the needle protector in a substantially 90 degree relative to the longitudinal axis of the base, the wings being movable between a compact, closed position surrounding the needle protector and an open, expanded position exposing the needle for insertion into the patient's anatomic space, the method comprising:
- moving the butterfly assembly into the open, expanded position exposing the needle and the needle protector;
- removing the needle protector;
- inserting the needle into a patient's anatomic space;
- and
- pressing the pair of wings against the patient without any significant biasing force tending to force wings into the closed position.
An infusion assembly for delivery of an infusion fluid into a patient's anatomic space at a substantially constant pressure, the infusion assembly comprising:
- a reservoir for the infusion fluid;
- and
- a pressurizing mechanism to deliver the infusion fluid from the reservoir into the patient's anatomic space at a substantially constant pressure, the pressurizing mechanism including a substantially constant force spring mechanism in contact with a pressurizer and an actuator to gradually load the substantially constant force spring mechanism.
