Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a sharps box for disassembling insulin pen needles. Background Art

[0002] An insulin pen is a pen cover device that can be inserted into an insulin pen cartridge and is used to inject insulin. Before injecting insulin, an insulin needle must be installed on the front end of the insulin pen. The insulin pen needle is different from an ordinary syringe needle. An ordinary syringe needle is directly placed on the syringe nipple. When handling sharp objects, use a traditional sharps box to slide the needle from the large hole to the small hole, and then lift it up to separate the needle. The insulin pen needle is threaded and rotated to the front end of the insulin pen, so it cannot be separated using a traditional sharps box.

[0003] At present, there are mainly the following ways for nurses to separate insulin pen needles in clinical practice: 1. Unscrew the insulin pen needle by hand and throw it back into the sharps box; 2. Put the outer cover of the insulin pen needle back onto the insulin needle, cover the needle tip, and then unscrew the needle; 3. Use hemostatic forceps to clamp the insulin needle and use the hemostatic forceps to unscrew the needle. Because the insulin needle is ultra-thin and ultra-short, it is very easy to cause needlestick injuries and iatrogenic infections when removing it by hand. In addition, clinical nursing operation specifications require that the needle must be re-covered with one hand to avoid being stabbed. The outer cover of the insulin needle is short and round, and it is not easy to re-cover the needle with one hand. Re-covering it with both hands can also easily cause nurses to be stabbed by needles. When using hemostatic forceps to separate the insulin pen needle, the inconvenience of operation increases the workload of nurses. Utility Model Content

[0004] The utility model aims to provide a sharps box for disassembling insulin pen needles, so as to solve the problems that the separation of existing insulin pen needles has certain risks of needle stick injuries and iatrogenic infections, increases the workload of nurses, and the existing traditional sharps box cannot separate them.

[0006] A sharps box for disassembling insulin pen needles, comprising a sharps box body, a box cover arranged at the top of the sharps box body, a rotating cover arranged above the center of the box cover, the rotating cover is connected to a rotating shaft, the rotating shaft is arranged on the box cover, a needle positioning sleeve is arranged below the rotating cover, a plurality of positioning grooves are arranged in a circular array on the inner circle of the needle positioning sleeve, a support plate is arranged below the needle positioning sleeve, the support plates are arranged to be symmetrically arranged with respect to the center line of the needle positioning sleeve, semicircular opening grooves are arranged at the ends close to each other of the two support plates, one end of the two support plates is connected to the output end of a drive adjustment component, and the drive adjustment component is arranged at the bottom of the box cover.

[0007] Optionally, a transparent viewing window is provided on the sharps box body, and the box cover and the sharps box body are snap-connected to be detachable.

[0008] Optionally, the drive adjustment component includes a transmission block, which is arranged in two left and right parts respectively connected with one end of the support plate, the transmission block is threadedly sleeved on the bidirectional screw rod, the bidirectional screw rod is arranged in a limiting groove, the limiting groove is opened in the mounting frame, the mounting frame is arranged at the bottom end of the box cover, the transmission block is slidably arranged in the limiting groove, a servo motor is arranged at one end of the bidirectional screw rod, and the servo motor is arranged on one end of the mounting frame.

[0009] Optionally, a control box, a power cord and an operating button are respectively arranged on the box cover, and the control box is electrically connected to the power cord, the operating button and the servo motor respectively.

[0010] Optionally, two semicircular opening grooves cooperate to form a through hole, and the through hole and the needle positioning sleeve are on the same center line.

[0011] The beneficial effects of the utility model are as follows: the cooperation of the needle positioning sleeve, the positioning groove and the support plate will facilitate the rapid disassembly of the insulin pen needle, while driving the adjustment component to adjust the spacing between the support plates will facilitate the free fall of the disassembled needle into the sharps box body, which has high working efficiency and avoids needle sticks and iatrogenic infections; the box cover cooperates with the rotating cover to achieve the effect of a sealed sharps box, thereby ensuring its safety.
