Description

Technical Field

[0001] The utility model relates to the technical field of medical waste treatment, in particular to a sharps box. Background Art

[0002] With the rapid development of medical technology, the amount of medical waste is increasing, and the treatment of sharp waste has become an important issue. Sharp waste, such as syringes, blades, suture needles, etc., poses a potential threat to the environment and personnel due to their sharp edges and tips. In the early days, there were no special sharps boxes for the treatment of medical waste, and medical staff usually used ordinary trash cans or plastic bags to collect sharp waste. However, this method has great safety hazards, because sharps can easily puncture trash cans or plastic bags, causing waste leakage and personal injury. In order to solve this problem, the field of medical waste treatment began to develop special sharps boxes. The original sharps boxes may be simple cardboard boxes or plastic boxes, but over time, their design and functions have been gradually improved and perfected. Modern sharps boxes are usually made of high-quality plastic materials, which are puncture-resistant and non-leakage-resistant, and have a closed and puncture-proof structure to ensure that under normal circumstances, the contents of the sharps box will not leak, and once sealed, it cannot be opened again without being destroyed. With the continuous advancement of medical waste treatment technology, the design of sharps boxes has become more and more humane and intelligent. Some modern sharps boxes are equipped with automatic cutting devices, which can easily cut sharps and improve processing efficiency. Some sharps boxes use intelligent sensing technology, which can automatically detect whether the waste is full and remind medical staff to replace it in time.

[0003] In the sharps box with patent number CN202021865998.9, the needle of the infusion needle is cut off by a shearing knife and collected in the box body. The shearing knife is operated by the handle part, but it is obvious that after cutting a needle, the shearing knife needs to be reset by the handle part before the next shearing can be performed, which is not efficient enough. In addition, syringes are mostly plastic products. When shearing, the end of the syringe is often sheared together with the needle. A large force needs to be applied during shearing. The moment the shearing is completed, the needle will fly around due to the large shearing force. In this patent, the shearing knife is a strip structure. When shearing, the placement hole is in an open state. The cut needle is likely to fly out of the placement hole and cause harm to the user. Finally, in this patent, when the user uses the handle part to shear the needle, the left hand generally holds the syringe to place the needle in the placement hole, and the right hand pushes the handle part to shear the needle. However, since the sharps box is lighter as a whole, a large force is required during shearing, which often causes the sharps box to move around during shearing, making it inconvenient to shear. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the utility model provides a sharps box with the advantages of automatically retracting the shear knife, improving shearing efficiency, preventing the sheared needles from flying out of the sharps box and causing harm to the user, and applying shearing force longitudinally to prevent the sharps box from moving around during shearing. This solves the problem that the traditional patent needs to reset the shear knife through the handle before the next shearing can be performed, the efficiency is not high, and the needles will fly around due to the large shearing force at the moment of shearing. When shearing, the placement hole is in an open state, and the sheared needles are likely to fly out of the placement hole and cause harm to the user. Since the sharps box is light overall, it requires a large force when shearing, which often causes the sharps box to move around during shearing, making it inconvenient to cut.

[0006] (II) Technical solution

[0007] In order to realize the above-mentioned automatic retraction of the shearing knife, improve the shearing efficiency, prevent the sheared needles from flying out of the sharps box to cause harm to the user, and apply shearing force longitudinally to prevent the sharps box from moving around during shearing, the utility model provides the following technical solutions: a sharps box, including a box body and a cover body, the cover body is buckled on the box body, the top of the cover body is provided with a placement opening, the top of the cover body is provided with a rotating shaft, the rotating shaft extends into the inside of the cover body, a shearing device is provided on the rotating shaft, the shearing device includes a sleeve, a shearing knife, an opening and closing plate, a handle and a push rod The sleeve is assembled on the rotating shaft, a limiting ring is arranged at the bottom of the rotating shaft, a sliding groove is arranged on the side of the cover body, the handle is arranged in the sliding groove, the shearing knife is arranged between the handle and the sleeve and can rotate around the rotating shaft, a vertical hole is arranged on the cover body, a button is assembled in the vertical hole, a connecting rod is hinged at the bottom of the button, a limiting piece is arranged inside the top surface of the cover body, a limiting hole is arranged on the limiting piece, a push rod is arranged on the side of the shearing knife opposite to the blade, the push rod is slidably arranged in the limiting hole, and the push rod is hinged to the connecting rod.

[0008] Preferably, an opening and closing plate is provided on the side of the shearing knife opposite to the blade, and the shape of the opening and closing plate is the same as that of the placement opening.

[0009] Preferably, the placement opening is in a fan shape.

[0010] Preferably, a latching opening is provided on a side of the placement opening away from the handle, and the latching opening is located near the center of the circle of the side.

[0011] Preferably, a wedge-shaped block is provided on a side of the sliding groove away from the handle, and a higher end of the wedge-shaped block is away from the handle.

[0012] Preferably, a mounting plate is provided at the bottom of the cover body, and the mounting plate is located on a side close to the opening and closing plate.

[0013] Preferably, a spring is provided between the mounting plate and the opening and closing plate.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a sharp tool box, which has the following beneficial effects:

[0016] The sharps box is used by the cooperation of the box body, the cover body and the shearing device. When it is necessary to shear and collect the needle of the syringe, the syringe needle is inserted into the locking port downward so that the needle tube can be fixed in the locking port, and then the button is pressed. The button moves downward to drive the connecting rod hinged to it to move downward, and further drives the push rod hinged to the connecting rod to move forward along the direction of the limiting hole. Finally, the push rod pushes the shearing knife to move toward the locking port to shear the needle located in the locking port. In this way, when shearing, it is only necessary to apply a vertical force to the button to achieve the shearing of the needle in the horizontal direction. The stability of the sharps box can be guaranteed during shearing, and the sharps box will not be pushed down due to the horizontal force applied during shearing, which makes shearing very inconvenient. During the movement of the shear knife toward the needle, since an opening and closing plate is provided on the other side of the shear knife, the opening and closing plate will also move toward the needle, gradually covering and closing the placement port. At the moment of shearing, the opening and closing plate will completely cover the entire placement port, so that the sheared needle will not fly out of the placement port due to the shearing force and may injure the user. After the shearing is completed, since a spring is provided on one side of the opening and closing plate, the spring is stretched during the shearing process. After the shearing is completed, the user does not apply a downward force to the button, and the restoring force of the spring will restore the opening and closing plate and the shear knife to their original positions. The user does not need to manually reset the shear knife after the shearing is completed, and then proceed to the next shearing, thereby improving work efficiency. When the volume of the sharps in the box body reaches two-thirds of the capacity of the entire box body, the sharps box needs to be closed to no longer receive sharps. At this time, the medical staff pushes the handle so that the handle is stuck in the wedge-shaped block, and the placement port is closed through the opening and closing plate. Thereby, the shear knife is automatically retracted, the shearing efficiency is improved, the sheared needle is prevented from flying out of the sharp tool box to cause harm to the user, and the shearing force is applied longitudinally to prevent the sharp tool box from moving around during shearing.

[0033] Working principle: When it is necessary to shear and collect the needle of the syringe, insert the needle of the syringe downward into the locking port 22 so that the needle tube can be fixed in the locking port 22, and then press the button 281. The button 281 moves downward to drive the connecting rod 282 hinged thereto to move downward, and further drives the push rod 35 hinged to the connecting rod 282 to move forward along the direction of the limiting hole 291. Finally, the push rod 35 pushes the shearing knife 32 to move toward the locking port 22 to shear the needle located in the locking port 22. In this way, when shearing, it is only necessary to apply a vertical force to the button 281 to achieve the shearing of the needle in the horizontal direction, which can ensure the stability of the sharps box during shearing, and the sharps box will not be pushed down due to the horizontal force applied during shearing, which makes shearing very inconvenient. During the movement of the shearing knife 32 toward the needle, since the opening and closing plate 33 is provided on the other side of the shearing knife 32, the opening and closing plate 33 will also move toward the needle, gradually covering and closing the placement port 21. At the moment of shearing, the opening and closing plate 33 will completely cover the entire placement port 21, so that the sheared needle will not fly out of the placement port 21 due to the shearing force and may hurt the user. After the shearing is completed, since a spring 27 is provided on one side of the opening and closing plate 33, the spring 27 is stretched during the shearing process. After the shearing is completed, the user does not apply a downward force to the button 281, and the restoring force of the spring 27 will restore the opening and closing plate 33 and the shearing knife 32 to their original positions. The user does not need to manually reset the shearing knife 32 after the shearing is completed, and then perform the next shearing, thereby improving work efficiency. When the volume of the sharps in the box body reaches two-thirds of the capacity of the entire box body 1, the sharps box needs to be closed and no longer collect sharps. At this time, the medical staff pushes the handle 34, so that the handle 34 is stuck in the wedge-shaped block 241, and the placement opening 21 is closed through the opening and closing plate 33. Thereby, the shearing knife 32 is automatically retracted, the shearing efficiency is improved, the sheared needle is prevented from flying out of the sharps box to cause harm to the user, and the shearing force is applied longitudinally to prevent the sharps box from moving around during shearing.
