Description

Technical Field

[0001] The invention relates to a medical waste collection container, in particular to a medical waste sharps box. Background Art

[0002] Sharps boxes are medical waste collection containers commonly used in medical institutions. They are used to collect used needles and other discarded sharp objects for unified treatment to avoid the spread of disease.

[0003] When collecting discarded sharp objects in the existing sharps box, the processing personnel need to first use scissors to cut the discarded sharp objects [such as the needle of the infusion set and the bottle stopper puncture device] outside the sharps box, and then put them into the sharps box. However, in actual use, the reasonable storage of scissors is a problem. If the scissors are placed directly on the treatment cart, there is a risk of falling when pushing; if they are placed in a drawer, they need to be searched for when using, which is inconvenient to use. Sometimes nurses do not cut them when they do not have time, and wait until the last minute to cut them together. This is very unsafe and prone to needlestick injuries. Because the needle for hanging water [that is, what we call scalp needle] and the infusion set can be separated, some nurses will directly separate the scalp needle and put it into the sharps box, but the sharps box placed on the treatment cart is generally small. The scalp needle and the hose behind it are placed in the sharps box together and occupy more space in the sharps box, resulting in the hose sometimes being exposed outside the sharps box, blocking the delivery port of the sharps box, affecting work efficiency.

[0004] Now there are also some sharps boxes with shearing mechanisms at the delivery port. For example, Chinese patent application number CN202120561626.5 discloses a sharps box with built-in scissors, including a sharps box body, a fixed base is installed at the lower end of the sharps box body, and a scissors box is installed at the inner upper end of the sharps box body. When in use, put the things to be cut into the trimming groove, pull the two pull rods, and the pull rods move along the pull rod groove until the scissors cut it short, release the pull rod, and the torsion spring pushes the scissors back to the starting position. However, its structure is relatively complicated and is not suitable for being set on a small sharps box. The Chinese patent with application number CN202021883315.2 discloses a sharps box with a shearing function, including a box body, a box cover detachably connected to the box body, and a movable blade; the box cover includes a fixed cover fixed to the box body and provided with a delivery port, and a movable cover rotatably mounted on the fixed cover; a fixed blade is provided on one side of the delivery port, and the movable blade is hinged to the fixed cover through a rotating shaft, and cooperates with the fixed blade to form a shearing device, which can directly separate the needle with an infusion hose when in use without the aid of tools, thereby reducing the risk of being stabbed by sharps and improving work efficiency. However, there is a lack of safety protection structure between the movable blade and the fixed blade of this sharps box, and nurses are at risk of being cut by the movable blade and the fixed blade when operating. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a medical waste sharps box which has an ingenious structure, reasonable design, simple manufacture, convenient use, and is safe and reliable.

[0006] The above-mentioned object of the present invention is achieved by the following technical solutions:

[0007] A medical waste sharps box comprises a box body and a box cover, wherein the box cover is provided with a delivery port, a movable cover plate is rotatably connected above the box cover, a hollow opening is provided on the movable cover plate, medical waste can be put in when the movable cover plate is rotated to the point where the hollow opening corresponds to the delivery port, and the delivery port can be completely covered when the movable cover plate is rotated to the point where the hollow opening is offset from the delivery port; the characteristic is that a V-shaped notch is provided at a position close to an outer edge of the box cover at the end of the delivery port in a clockwise direction and / or a counterclockwise direction, the tip of the V-shaped notch faces in a clockwise direction and / or a counterclockwise direction, a shearing blade is provided near the end of the inner side edge of the V-shaped notch, the width of the V-shaped notch at the starting end of the shearing blade does not exceed 12 mm, and the side of the hollow opening facing the V-shaped notch is set as a convex arc edge.

[0008] As a further improvement of the present invention, the width of the V-shaped notch at the starting end of the shearing blade is 10 mm.

[0009] As a further improvement of the present invention, the cutting edge of the shearing blade is a straight cutting edge or a toothed cutting edge.

[0010] As a further improvement of the present invention, the cutting edge of the shearing blade is convex arc-shaped.

[0011] As a further improvement of the present invention, a plurality of arc-shaped grooves are provided on the side of the movable cover.

[0012] As a further improvement of the present invention, a convex shaft portion is provided at the center of the top of the box cover, and a sleeve portion is provided at the center of the movable cover plate. The sleeve portion is rotatably sleeved on the convex shaft portion and is limited by screws.

[0013] As a further improvement of the present invention, a torsion spring is installed on the convex shaft portion, a hook head at one end of the torsion spring is hooked on the convex shaft portion, and a hook head at the other end of the torsion spring is hooked on the sleeve portion, and the torsion spring drives the movable cover plate to automatically block the delivery port when no force is applied.

[0014] As a further improvement of the present invention, the box body, the box cover and the movable cover plate are made of plastic, and the shear blade is fixed on the box cover by injection molding.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1) The present invention cleverly arranges a V-shaped notch at the delivery port, and arranges a shearing blade on the inner side of the V-shaped notch near the end, thereby ensuring that the fingers of medical staff cannot touch the shearing blade, thereby avoiding accidents in which the shearing blade cuts the medical staff; at the same time, by setting the side of the hollow opening on the movable cover plate corresponding to the V-shaped notch as a convex arc edge, the convex arc edge will push the leather strip placed in the V-shaped notch outwards during the process of gradually moving toward the V-shaped notch, so that the leather strip is cut by the shearing blade. The V-shaped notch plays a limiting role on the leather strip in this process, ensuring that the leather strip will not slide accidentally during the shearing process.

[0017] 2) The present invention arranges a torsion spring between the box cover and the movable cover plate, so that the movable cover plate automatically blocks the delivery port on the box cover when no force is applied, so that the entire sharps box is completely closed under normal conditions, effectively ensuring medical safety.

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0025] like Figure 1 to Figure 4 As shown, the embodiment discloses a medical waste sharps box, which is mainly composed of a box body 1, a box cover 2, a movable cover plate 3, a shear blade 4, a screw 5, a torsion spring 6 and other components.

[0026] The box cover 2 is provided with a delivery port 2a, and a movable cover plate 3 is rotatably connected to the top of the box cover 2, and a hollow opening 3a is provided on the movable cover plate 3. When the movable cover plate 3 is rotated to the point where the hollow opening 3a corresponds to the delivery port 2a, medical waste can be put in. When the movable cover plate 3 is rotated to the point where the hollow opening 3a is offset from the delivery port 2a, the delivery port 2a can be completely covered. A V-shaped notch 2b close to the outer edge of the box cover 2 is provided at the end of the delivery port 2a in the clockwise direction, and the tip of the V-shaped notch 2b is also facing in the clockwise direction. A shearing blade 4 is provided near the end of the inner side of the V-shaped notch 2b, and the width of the V-shaped notch 2b at the starting end of the shearing blade 4 does not exceed 12 mm [the diameter of the thinnest finger of a normal adult]. The side of the hollow opening 3a facing the V-shaped notch 2b is set as a convex arc edge 3b.

[0027] In clinical use, when it is necessary to separate a sharp object [such as an infusion needle] and put it into the sharps box, first rotate the movable cover plate 3 so that the hollow opening 3a corresponds to the position of the delivery port 2a. At this time, the infusion needle can be inserted into the sharps box through the hollow opening 3a and the delivery port 2a, and the leather strip at the tail of the needle is placed in the V-shaped notch 2b. Then rotate the movable cover plate 3 so that the convex arc edge 3b of the hollow opening 3a moves toward the V-shaped notch 2b. The convex arc edge 3b will push the leather strip placed in the V-shaped notch 2b outward [i.e., the end direction of the V-shaped notch 2b] during the gradual movement. As the pushing force gradually increases, the leather strip will be cut off by the shear blade 4, and the infusion needle will automatically fall into the box body 1. The present invention arranges the shear blade 4 in the V-shaped notch 2b, so that the fingers of medical personnel can be prevented from contacting the shear blade 4 by only ensuring that the width at the starting end of the shear blade 4 is smaller than the diameter of an ordinary finger, thereby avoiding accidents in which the medical personnel are cut by the shear blade 4. At the same time, the V-shaped notch 2b can also play a good role in limiting the position of the leather strap, ensuring that the leather strap will not accidentally slide during the shearing process.

[0028] like Figure 2 , Figure 3 As shown, in this embodiment, the cutting edge of the shear blade 4 is a straight cutting edge. In actual production and manufacturing, the cutting edge of the shear blade 4 can also be a toothed cutting edge, and the tooth tip of the toothed cutting edge can better penetrate the leather strip to improve the shearing performance. The cutting edge of the shear blade 4 is preferably set to a convex arc shape, so that the two shear blades can make the leather strip be squeezed and flattened at the shearing force point and the inner wall fits, which is convenient for smooth cutting.

[0029] like Figure 2 , Figure 4 As shown, in this embodiment, a plurality of arc-shaped grooves 3c are provided on the side of the movable cover plate 3, so that when the medical staff rotates the movable cover plate 3, their fingers can be placed in the arc-shaped grooves 3c accordingly, which makes the operation more labor-saving.

[0030] like Figure 2 to Figure 5As shown, in this embodiment, a convex shaft portion 2c is provided at the center of the top of the box cover 2, and a sleeve portion 3d is provided at the center of the movable cover plate 3. The sleeve portion 3d is rotatably sleeved on the convex shaft portion 2c and limited by a screw 5. A torsion spring 6 is installed on the convex shaft portion 2c, and a hook at one end of the torsion spring 6 is hooked on the convex shaft portion 2c, and a hook at the other end of the torsion spring 6 is hooked on the sleeve portion 3d. The torsion spring 6 drives the movable cover plate 3 to automatically block the delivery port 2a when no force is applied. In this way, the movable cover plate 3 automatically blocks the delivery port 2a on the box cover 2 when no force is applied, so that the entire sharps box is completely closed under normal conditions, effectively ensuring medical safety.

[0031] In the present invention, the box body 1 , the box cover 2 and the movable cover plate 3 are preferably made of plastic, and the shear blade 4 is fixed on the box cover 2 by injection molding.

[0032] The above description is only a preferred embodiment of the present invention, and the above specific embodiment is not intended to limit the present invention. Various deformations and modifications may occur within the scope of the technical concept of the present invention, and any modification, modification or equivalent replacement made by a person of ordinary skill in the art based on the above description shall fall within the scope of protection of the present invention.
