Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 3, 4, 5, 7, 8, the sharp instrument box that can dismantle insulin pen needle includes box body 2, lid 3 and the syringe needle puller 1 of being connected with lid 3, syringe needle puller 1 is including dismantling cover 11, dismantle and have dismantlement hole 111 on the cover 11, dismantle concave 112 of dismantling that has a plurality of circumference equipartitions on the pore wall of hole 111, lid 3 is last to have box cover hole 31, syringe needle puller 1 passes through from box cover hole 31, it is articulated with lid 3 to dismantle cover 11, syringe needle puller 1 can 360 rotations, during syringe needle puller 1 free state, dismantlement hole 111 is towards the top.

As shown in fig. 8, the needle 5 is inserted into the removal hole 111, and the removal recess 112 is fitted into the needle recess 51. Then the insulin pen is rotated, and the needle 5 can be separated from the insulin pen by rotating the insulin pen because the disassembly concave bulge 112 is embedded into the needle groove 51 to limit the rotation of the needle 5. Then the needle detacher 1 is slightly pulled to rotate until the detaching hole 111 faces downwards, and the needle 5 can slide out and fall into the sharp instrument box by means of the self gravity.

The removal hole 111 and the removal projection 112 should obviously match the needle 5 and the needle recess 51. The needle head 5 can not be guaranteed to have a proper clearance between the disassembling sleeve 11 and the needle head 5 under the premise of rotating in the disassembling sleeve 11, so that the needle head 5 can slide out of the disassembling sleeve 11 by means of self gravity when the disassembling hole 111 faces downwards.

"dismantle cover 11 and lid 3 articulated", connect pivot 12 on dismantling cover 11 to set up the hinge hole on lid 3, pivot 12 inserts the hinge hole and with hinge hole clearance fit can. The shaft 12 preferably fits loosely into the hinge hole so that there is no significant resistance to rotation of the needle remover 1.

"the detaching hole 111 faces upward when the needle detacher 1 is in the free state", which is realized by that the part a of the needle detacher 1 shown in fig. 4 is heavy and the part B is light, and the torque generated by the gravity of the part a is larger than the torque generated by the gravity of the part B by a certain value. The gravity distribution of the needle detacher 1 and the position of the rotating shaft 12 can be reasonably arranged.

In order to further simplify the operation, the needle detacher 1 of the present invention can be automatically rotated to the detaching hole 111 to face downward when the needle 5 is preferably provided in the detaching hole 111. After the needle 5 is separated from the insulin pen, the needle 5 is located in the detaching hole 111, so that the gravity of the upper part (part a shown in fig. 4) of the needle detacher 1 is obviously increased, and the gravity of the lower part (part B shown in fig. 4) of the needle detacher 1 is not obviously increased, so that the torque generated by the upper part of the needle detacher 1 is obviously increased, and the needle detacher 1 can automatically rotate to the detaching hole 111 and face downwards. The same rational arrangement of the gravity distribution of the needle remover 1 and the position of the axis of rotation 12 is achieved.

As mentioned above, there is a suitable gap between the removing sleeve 11 and the needle 5, so that when the needle remover 1 is rotated until the removing hole 111 faces downwards, the needle 5 can slide out by its own weight and fall into the sharp box. In order to further improve the reliability, the needle head 5 can be made to fall out when the needle head 5 does not automatically slide out under special conditions, the utility model discloses can further improve as follows: as shown in fig. 6, the needle detacher 1 comprises a moving sleeve 13 and a spring 14, the moving sleeve 13 is arranged in cooperation with the detaching sleeve 11, the moving sleeve 13 extends out of the detaching sleeve 11 from the bottom of the detaching hole 111, the spring 14 is sleeved on an exposed part of the moving sleeve 13, one end of the spring 14 abuts against the detaching sleeve 11, and the other end of the spring 14 outwards supports the moving sleeve 13. Thus, the movable sleeve 13 is pressed, and the needle 5 can be ejected by the movable sleeve 13. The spring 14 can return the moving sleeve 13.

In particular, the mobile sleeve 13 may have an upper flange 131 and a lower flange 132, the upper flange 131 being intended to rest against the bottom of the removal hole 111, the lower flange 132 being intended to be supported by the spring 14.

When the needle detacher 1 includes the moving sleeve 13 and the spring 14, as shown in fig. 6, "when the needle detacher 1 is in the free state, the detaching hole 111 faces upward" and "when the needle 5 is provided in the detaching hole 111, the needle detacher 1 can be automatically rotated to the detaching hole 111 to face downward" can be realized by reasonably setting the mass of the C portion and the D portion of the needle detacher 1.

As shown in fig. 8, the cap hole 31 requires a certain length to leave a sufficient space since the needle remover 1 needs to be rotated. A small cover 4 can be arranged, the small cover 4 is connected with the box cover 3 and covers the needle head detacher 1 and the box cover hole 31, so that covering is realized, and the needle head 5 is prevented from being exposed from the box cover hole 31 when the sharp instrument box is overturned accidentally. When the needle head 5 is detached, the small cover 4 is opened.
