A needle retraction medical device including a hollow body (10) and a plunger (20). The hollow body (10) has a first end (11) provided with a needle mounting hub (13) and a plurality of releasable latches (15) holding the needle mounting hub (13) against spring (14) bias. The latches (15) are formed integrally with the hollow body (10) and project longitudinally inside the hollow body (10) from a proximal end at or adjacent the first end (11) of the hollow body (10) to a free end. A respective opening (35) is provided in the body (10) radially inwards of each of the latches (15). The plunger (20) has a forward end insertable into the body (10) from a second end thereof, a hollow interior and a closed rear end. The plunger front end is operable, upon insertion of the plunger (20) into the body (10), to deflect the latches (15) radially outwards and thereby release the needle mounting hub (13) from the latches (15) so that the hub (13) together with the needle mounted thereby retract under spring action into the hollow interior of the plunger (20). A respective opening (30) is also provided in the hollow body (10) radially outwards of at least some of the latches (15) so that each such latch (15) connects to the material of the body (10) only at each side of its proximal end.
A needle retraction medical device comprising a hollow body having a first end and a second end, said first end being provided with a needle mounting hub and with a plurality of releasable latches holding said needle mounting hub against spring bias, the latches being formed integrally with the hollow body and projecting longitudinally inside the hollow body from a proximal end at or adjacent the first end of the hollow body to a free end, and a respective opening being provided in the body radially inwards of each of the latches, and a plunger having a forward end insertable into the body from the second end, a hollow interior and a closed rear end, said plunger front end being operable, upon insertion of the plunger into the body, to deflect the latches radially outwards and thereby release the needle mounting hub from the latches so that the hub together with the needle mounted thereby retract under spring action into the hollow interior of the plunger, wherein a respective opening is also provided in the hollow body radially outwards of at least some of the latches so that each such latch connects to the material of the body only at each side of its proximal end.
A needle retraction medical device comprising a hollow body having a first end and a second end, said first end being provided with a plurality of releasable latches for holding a needle mounting hub against spring bias, the latches being formed integrally with the hollow body and projecting longitudinally inside the hollow body from a proximal end at or adjacent the first end of the hollow body to a free end, and a respective opening being provided in the first end of the body radially inwards of each of the latches, wherein a respective opening is also provided in the hollow body radially outwards of at least some of the latches so that each such latch connects to the material of the body only at each side of its proximal end.
