Abstract
A removal system and method to facilitate removal of a sheath from a medical device such as a hypodermic needle. The removal system comprises a sheath having an exterior housing defining an internal cavity for accommodating a hypodermic needle therein. The sheath is open at one end thereof to facilitate receiving the hypodermic needle therein. An exterior surface of the sheath supports at least one appendage comprising at least one tension leg which interconnects a pushing surface with the sheath. The at least one tension leg partially bows, once a sufficient removal force is applied thereto, facilitating removal of the sheath from a hypodermic needle via a clinician via a one handed technique.
Claims17
A removal system to facilitate removal of a sheath from a medical device by an operator using one hand, the medical device defining a longitudinal axis, the removal system comprising:
- a sheath having an exterior housing defining an internal cavity for accommodating a medical device therein, the sheath being open at least one end thereof to facilitate receiving at least a portion of the medical device within the exterior housing;
- an exterior surface of the sheath supporting at least one appendage thereof, and the at least one appendage, once a sufficient force is applied thereto, inducing movement of the sheath along the longitudinal axis, in a direction away from the medical device, to facilitate automatic removal of the sheath from the medical device solely by actuation of the at least one appendage;
- and
- the at least one appendage is adapted such that force applied substantially perpendicularly to the longitudinal axis induces a force in the sheath directed along the longitudinal axis in a direction away from the medical device thereby facilitating removal of the sheath from the medical device.
A removal system to facilitate removal of a sheath from a medical device by an operator using one hand, the medical device defining a longitudinal axis, the removal system comprising:
- a sheath having an exterior housing defining an internal cavity for accommodating a medical device therein, the sheath being open at least one end thereof to facilitate receiving at least a portion of the medical device within the exterior housing;
- an exterior surface of the sheath supporting at least one appendage thereof, and the at least one appendage, once a sufficient force is applied thereto, inducing movement of the sheath along the longitudinal axis, in a direction away from the medical device, to facilitate automatic removal of the sheath from the medical device solely by actuation of the at least one appendage;
- and
- a pair of appendages are provided to facilitate removal of the sheath, each one of the pair of appendages comprises a generally C-shaped appendage with a pushing surface, and a tension leg interconnects the pushing surface with a proximal end of the sheath, and the tension leg facilitates generating a thrusting force on the sheath, once the pushing surfaces are sufficiently biased towards one another, to thrust the sheath longitudinally along the longitudinal axis, defined by the medical device, to remove the sheath from the medical device while minimizing possible damage to the medical device.
A removal system to facilitate removal of a sheath from a hypodermic needle by an operator using one hand, the hypodermic needle defining a longitudinal axis, the removal system comprising:
- a sheath having an exterior housing defining an internal cavity for accommodating a hypodermic needle therein, and the sheath being open at least one end thereof to facilitate receiving a hypodermic needle therein;
- an exterior surface of the sheath supporting at least one appendage thereof, the at least one appendage comprising at least one tension leg which interconnects a pushing surface with the sheath, the at least one tension leg partially bows, once a sufficient removal force is applied thereto to induce movement of the sheath along the longitudinal axis, in a direction away from the hypodermic needle, to facilitate automatic removal of the sheath from the hypodermic needle solely by actuation of the at least one appendage;
- and p1 the at least one appendage is adapted such that force applied substantially perpendicularly toward the longitudinal axis of the hypodermic needle is directed along the longitudinal axis in a direction facilitating removal of the sheath from the hypodermic needle.
A method of facilitating removal of a sheath from a medical device by an operator using one hand the method comprising the steps of:
- defining a longitudinal axis with the medical device;
- providing a sheath with an exterior housing defining an internal cavity for accommodating a medical device therein, and the sheath being open at least one end thereof to facilitate receiving a medical device therein;
- supporting at least one appendage by an exterior surface of the sheath;
- once a sufficient force is applied thereto, the at least one appendage inducing movement of the sheath along the longitudinal axis, in a direction away from the medical device, to facilitate automatic removal of the sheath from the medical device solely imply by actuation of the at least one appendage;
- and
- applying a force to the at least one appendage substantially perpendicularly to the longitudinal axis of the sheath so that the at least one appendage induces movement of the sheath along the longitudinal axis in a direction away from the medical device to facilitate removal of the sheath from the medical device.
