Abstract

There is disclosed a fluid handling device (2) having a needle retraction assembly adapted to bring about the retraction of a hollow needle (10) after use comprising a hollow body portion (4) provided at one end thereof with an end wall having a mounting portion (8) including a needle passage, and a hollow needle (10) having a mounting means and adapted to be movable between a first position in which a leading end portion of the needle protrudes from a front end portion of said mounting portion (8) and a second position in which the needle is withdrawn within the hollow body portion (4), said mounting means including resilient means (28) that act to bias the needle (10) into the second, withdrawn, position, said needle (10) being provided with an enlarged portion (18) at a location spaced from the leading end portion thereof, there being provided retaining means to maintain the needle in its first position until use is completed, said retaining means comprising in combination an O-ring (20) positioned in a circumferential groove (19) in said enlarged portion (18) and abutting the end of a sleeve (36) which can be forced forwardly to dislodge the O-ring (20) so as to permit the needle (10) to move from its first position into its second position under the influence of said resilient means (28).
