FIELD: medicine.SUBSTANCE: invention relates to hinged panel devices designed with possibility to protect needle for preventing pricks. Panel comprises needle sleeve which includes the first part of hinge whereupon the needle projects from the needle sleeve; and panel including the second part of hinge which engages with the first part of hinge to fix the panel to the needle sleeve with possibility of rotation, whereupon the panel additionally includes several side walls made with possibility of partial needle surrounding when the panel device is in protective position. Whereupon the first part of hinge on needle sleeve makes first seat and second seat, and the second part of hinge on panel forms the first ball bearing and the second ball bearing, each of which has multiple faces extending partially along the circumference, wherein the first and second seats receive first and second ball bearings into mutual engagement with the possibility of rotation so that friction and tightness between the first and second seats and first and second ball bearings set panel at required angle relative to the needle.EFFECT: using the invention enables to maintain panel at any desired orientation relative to the needle sleeve, without the need for manual gripping or retention of flap.20 cl, 40 dwg |
