Safety shield

A safety shield comprising:

• a piercing member having a proximal end, a distal end and defining a longitudinal axis;
• a housing having an outer surface;
• and
• a clip including a plate oriented in an axis transverse to the longitudinal axis of the piercing member and defining a cavity, the cavity being dimensioned for movement of the piercing member therethrough, the clip being rotatable from a first orientation to a second orientation to reposition the cavity relative to the longitudinal axis of the piercing member from a sliding orientation to a binding orientation whereby a surface of the plate that defines the cavity engages the piercing member to prevent slidable movement thereof,
• the clip including a first leg extending from the plate and having a proximal part and a distal part, the distal part defining a cavity dimensioned for movement of the piercing member therethrough and the distal part being configured to engage a medical device when the clip is in the first orientation, the clip including a second leg that extends from the plate and has a proximal part and a distal part, the distal part of the second leg including a bearing surface that engages the piercing member when the clip is in both the first orientation and the second orientation;
• wherein the legs are resiliently biased for convergent movement toward each other such that when the piercing member is withdrawn from the cavity defined by the distal part of the first leg, the clip moves from the first orientation to the second orientation to move the first cavity from the sliding orientation to the binding orientation, wherein the distal part of the first leg disengages the medical device when the clip is in the second orientation.

A safety needle shield apparatus comprising:

• a needle having a proximal end, a distal end and defining a longitudinal axis;
• a housing having an outer surface and being movable between an retracted position whereby the distal end of the needle is exposed and an extended position whereby the distal end of the piercing member is enclosed within the housing, the housing being substantially transparent and defining a flash chamber;
• and
• a clip including a plate oriented in an axis transverse to the longitudinal axis of the needle and defining a slot dimensioned for movement of the needle therethrough, the clip being rotatable from a first orientation to a second orientation to reposition the cavity relative to the longitudinal axis of the needle from a sliding orientation to a binding orientation whereby a surface of the plate that defines the cavity engages the needle to prevent slidable movement thereof,
• the clip including a first leg extending from the plate and having a proximal part and a distal part, the distal part defining a cavity dimensioned for movement of the needle therethrough such that disposal of the needle in the cavity of the distal part prevents transverse movement of the first leg, the distal part of the first leg including an arm configured to releasably retain a catheter hub in engagement with the outer surface of the housing when the clip is in the first orientation,
• the clip further including a second leg that extends from the plate and has a proximal part and a distal part, the distal part of the second leg including a bearing surface that engages the needle in both the first orientation and the second orientation of the clip,
• wherein the legs are resiliently biased for convergent movement toward each other such that when the needle is withdrawn from the cavity defined by the distal part of the first leg, the clip moves from the first orientation to the second orientation to move the first cavity from the sliding orientation to the binding orientation, wherein the arm of the first leg releases the catheter hub and the bearing surface of the second leg engages the needle to prevent movement of the needle when the clip is in the second orientation.

A safety needle shield comprising:

• a needle having a distal end and defining a longitudinal axis;
• and
• a clip defining a first cavity dimensioned for movement of the needle therethrough, the first cavity oriented in an axis transverse to the longitudinal axis of the needle, the clip being movable from a first orientation to a second orientation to reposition the first cavity from a movable orientation to a binding orientation;
• the clip including a first leg that defines a second cavity dimensioned for movement of the needle therethrough, wherein the first leg has a distal part being configured to engage a medical device when the clip is in the first orientation, the clip further including a second leg having a bearing surface that engages the needle when the clip is in both the first orientation and the second orientation, the distal part of the first leg releasably engaging the second leg when the clip is in the first orientation;
• wherein the first leg and the second leg are biased for convergent movement toward each other such that when the needle is withdrawn form the second cavity, the clip moves from a first orientation to a second orientation to move the first cavity from the movable orientation to the binding orientation, wherein the distal part of the first leg disengages from the second leg and the medical device when the clip is in the second orientation.

A medical clip adapted for use with a piercing member having a distal end and defining a longitudinal axis, the clip comprising:

• a first cavity dimensioned for movement of the piercing member therethrough and being oriented in an axis transverse to the longitudinal axis of the piercing member, the clip being rotatable from a first orientation to a second orientation to reposition the first cavity relative to the longitudinal axis of the piercing member from a movable orientation to a binding orientation;
• a first leg that defines a distal part extending therefrom and a second cavity, the second cavity being disposed distal to the first cavity and dimensioned for movement of the piercing member therethrough;
• and
• a second leg having a bearing surface configured to engage the piercing member in both the first orientation and the second orientation of the clip,
• wherein the first leg and the second leg are, relative to the first and second legs, biased for convergent movement toward each other such that when the piercing member is withdrawn form the second cavity of the first leg, the clip moves from the first orientation to the second orientation to move the first cavity from the movable orientation to the binding orientation.

A safety shield comprising:

• a piercing member having a distal end and defining a longitudinal axis;
• and
• a clip defining a first cavity dimensioned for movement of the piercing member therethrough and being oriented in an axis transverse to the longitudinal axis of the piercing member, the clip being movable from a first orientation to a second orientation to reposition the first cavity from a movable orientation to a binding orientation;
• the clip including a first leg that defines a second cavity dimensioned for movement of the piercing member therethrough and a distal part being configured to engage a medical device when the clip is in the first orientation, the clip further including a second leg having a network of biasing elements configured to bias the clip and a bearing surface that engages the piercing member in both the first orientation and the second orientation of the clip, the biasing elements of the network defining channels therebetween and being connected to form a continuous spring element;
• wherein the first leg and the second leg are biased for convergent toward each other movement such that when the piercing member is withdrawn form the second cavity of the first leg, the clip moves from the first orientation to the second orientation to move the first cavity from the movable orientation to the binding orientation, wherein the distal part of the first leg disengages the medical device when the clip is in the second orientation.
