Description
Technical Field
[0001] The utility model relates to a sharps box and belongs to the field of medical waste recycling. Background Art
[0002] A sharps box is an essential container for clinical treatment of medical sharps waste, and is mainly used to collect sharps such as syringes or infusion set needles. Currently, the commonly used sharps box is a plastic container with a throwing hole in the lid, but the needle at the front end and the needle at the rear end of the infusion set are connected to a hose. Before putting the needle into the sharps box, the needle needs to be cut off from the hose. Therefore, medical staff usually carry scissors to cut the needle of the infusion set with the scissors. Such operation is very inconvenient, and carrying scissors is relatively troublesome and dangerous.
[0003] At present, there are also some sharps boxes with a cutting function. These sharps boxes with a cutting function usually have a cutting knife at the throwing port on the box cover. When in use, the needle of the infusion set is inserted into the throwing port, and then the hose at the root of the needle is cut by turning or rotating the cutting knife, and the cut needle falls into the box body; however, it is found in actual clinical use that when medical staff turn or rotate the cutting knife, they need to apply force with their fingers, which is relatively strenuous. Since the operation of cutting the needle from the infusion set is frequent every day in clinical practice, the finger fatigue of medical staff will also increase accordingly. Utility Model Content

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] like Figure 1-7 As shown, this embodiment is a sharp tool box, including a box body 1 and a shearing assembly. The box body 1 is a hollow cylindrical structure. A throwing port 2 is arranged on the side wall of the box body 1. The shearing assembly includes a shearing portion 3, an arc-shaped cutting knife 4, a guide column 5, a spring 6 and a pressing portion 7. The shearing portion 3 is arranged inside the box body 1, and the arc-shaped cutting knife 4 is arranged on the shearing portion 3, and the blade of the arc-shaped cutting knife 4 is vertically downward. The blade of the arc-shaped cutting knife 4 is in sliding contact with the inner circumferential surface of the box body 1 around the throwing port 2. The bottom end of the guide column 5 is connected to the shearing portion 3. A hole 10 for the guide column 5 to pass through is arranged on the top of the box body 1. The top end of the guide column 5 passes through the top of the box body 1 and is connected to the pressing portion 7. The spring 6 is sleeved on the guide column 5 between the pressing portion 7 and the top of the box body 1.
[0031] In this embodiment, the shearing portion 3 is a circular groove structure with an opening facing downward, the outer circumference of the shearing portion 3 is clearance-matched with the inner circumference of the box body 1 , and the arc-shaped cutting blade 4 is arranged on the outer circumferential side wall of the shearing portion 3 .
[0032] In order to prevent the shearing assembly from rotating, the cross-sectional shape of the guide post 5 is designed to be non-circular, and the shape of the hole 10 at the top of the box body 1 is consistent with the cross-sectional shape of the guide post 5. In this embodiment, the cross-sectional shape of the guide post 5 is elliptical, and the shape of the hole 10 at the top of the box body 1 is an ellipse consistent with the cross-sectional shape of the guide post 5; in actual application, the cross-sectional shape of the guide post 5 can also be rectangular; thereby, the shearing assembly can only be displaced in the vertical direction, preventing the shearing assembly from rotating in the circumferential direction.
[0033] In this embodiment, the top surface of the pressing part 7 is a spherical structure, so that the top surface of the pressing part 7 fits the palm more closely; a silicone pad layer 8 is provided on the top surface of the pressing part 7, and the silicone pad layer 8 plays an anti-slip and decompression role, thereby increasing the comfort of the palm when pressing.
[0034] In this embodiment, a needle-pulling slot 9 is provided on the side wall of the throwing port 2, and the needle-pulling slot 9 is used to pull out the needle of the syringe.
[0035] In this embodiment, a threaded structure 11 is provided on the outer circumferential surface of the box body 1 near the bottom of the box body 1, and a threaded groove is provided on the external carrying device, and the box body 1 is threadedly connected to the threaded groove of the external carrying device; thereby, the box body 1 and the external carrying device are detachably connected. When the box body 1 is connected to the external carrying device, the box body 1 is in a fixed state and will not tip over or slide, and is also convenient for pressing operations; the external carrying device can be a nursing tray or a nursing cart.
[0036] As another embodiment, a trumpet-shaped structure 12 for guiding the needle to be inserted into the throwing port 2 is provided outside the throwing port 2. The trumpet-shaped structure 12 can enlarge the opening of the throwing port 2, so as to facilitate accurate insertion of the needle into the throwing port 2; Figure 8 shown.
[0037] When using this embodiment, firstly, the box body 1 is connected to the external bearing device so that the box body 1 is in a fixed state;
[0038] When the infusion set needle needs to be cut off, first insert the infusion set needle into the throwing port 2. Figure 2 Then, the pressing portion 7 is pressed downward by the palm of the hand, and the pressing portion 7 drives the shearing portion 3 and the arc-shaped cutting knife 4 to move downward through the guide column 5. The arc-shaped cutting knife 4 cuts off the hose at the root of the infusion needle during the downward movement. Figure 3As shown; the cut infusion needle falls and is stored inside the box body 1; after the palm is separated from the pressing part 7, the compressed spring 6 releases the elastic force, pushing the pressing part 7 to move upward, and the pressing part 7 drives the shearing part 3 and the arc-shaped cutting knife 4 to move upward through the guide column 5 and return to the initial state.
[0039] When it is necessary to remove the syringe needle, first insert the syringe needle into the ejection port 2, then clamp the connection gap between the syringe tube and the needle in the needle removal slot 9, and then pull the syringe tube outward to separate the syringe needle from the syringe tube. The separated needle falls and is stored inside the box body 1.
[0040] When the box body 1 is recycled, a sealing plug is plugged at the throwing port 2. Of course, a sealing sticker can also be adhered to the throwing port 2. The sealing plug or sealing sticker is used to block the throwing port 2 to prevent the box body 1 from leaking during the recycling process.
[0041] The utility model provides a throwing port on the side of the box body for collecting medical sharp waste. The palm of the hand applies force and the infusion needle is cut off by pressing the palm. The palm force is relatively more convenient and labor-saving. The use process is simple and convenient, so that medical staff can be more convenient and labor-saving in the frequent operation of cutting the infusion needle.
