Needle retracting mechnism, needle holder and hypodermic syringe
An automatic needle retracting mechanism ( 1 ) for a hypodermic syringe ( 2 ) comprises a body ( 3 ) which slidingly supports a needle ( 27 ). A retainer ( 9 ) for an actuator ( 8 ) and the needle ( 27 ) is kept in a retaining position by a spacer ( 11 ), which after some time in contact with an inj...

| description | An automatic needle retracting mechanism (
1
) for a hypodermic syringe (
2
) comprises a body (
3
) which slidingly supports a needle (
27
). A retainer (
9
) for an actuator (
8
) and the needle (
27
) is kept in a retaining position by a spacer (
11
), which after some time in contact with an injectant loses its mechanical strength. A filing of the needle with an injectant causes a deformation of the spacer (
11
), a release of the actuator (
8
) and a retracting of the retainer (
9
) and needle (
27
) into a needle retraction chamber (
4
). The needle retracting mechanism may also include an inner sleeve (
20
) which is manually movable towards the retainer (
9
) for a manual release of the actuator (
8
). The needle retracting mechanism may be included in a needle holder (
33
) or integrated in a syringe (
2
′). |
