Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and specifically relates to a clinical sharp instrument storage box with cutting function. Background Technology

[0002] A sharps container is a medical storage box used to collect sharp instruments such as syringes, small glass objects, blades, suture needles, and blood collection needles. Sharps containers are for single use only and, according to national regulations, must be collected by medical waste disposal units within 24 hours and completely and safely incinerated within 48 hours. During clinical diagnosis, treatment, nursing, and laboratory operations, a large number of sharp instruments such as needles, glass ampoules, and metal suture needles are generated. These instruments carry bodily fluids, medications, or pathogens, and improper handling can easily cause punctures or cuts to personnel, leading to cross-infection and environmental pollution. Therefore, safe and efficient sharps collection and disposal devices are a core necessity in medical settings.

[0003] In existing technologies, medical staff need to manually use tools such as scissors and hemostats to cut needles (such as infusion needles and syringe needles) and then put the cut sharp objects into a box. However, during use, the gap between the fixed blades and the cutting force cannot be adjusted, making it difficult to adapt to sharp objects of different diameters and hardness. Problems such as jamming and cutting failure are prone to occur. Manual cutting tools (such as scissors and hemostats) repeatedly come into contact with different sharp objects. If they are not disinfected in time and thoroughly, they can easily become a medium for the spread of pathogens. Moreover, the body fluids and medications after cutting can easily adhere to the surface of the tools, causing contamination of the operating table and failing to effectively improve the safety of medical staff's work.

[0004] Therefore, it is necessary to invent a clinical instrument storage box with a cutting function to solve the above problems. Summary of the Invention

A through hole is opened in the middle of the placement block for placing the tube and needle to be cut. The moving block is connected to both sides of the placement block by springs.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] This invention provides a clinical sharps storage box with a cutting function, such as... Figures 1 to 6 As shown, the device includes a box body 1, a lid 2, a rotating cover 3, a moving structure, and a shearing mechanism. The lid 2 is located on the top of the box body 1 and has a rotating groove. The bottom of the rotating cover 3 is rotatably connected to the rotating groove for sealing and protecting the box body 1. The moving structure is connected to the bottom of the lid 2 and is parallel to the bottom of the lid 2. Two shearing mechanisms are located at the bottom of the moving structure, each with a different shearing force to accommodate different sharp objects. A rotating structure is located between the two shearing mechanisms for switching between them. Both the lid 2 and the rotating cover 3 have placement openings 6 on their tops for placing sharp objects. A limiting structure is provided on the side wall of the placement opening 6 to limit the sharp object. A controller 7 is fixedly connected to the outside of the lid 2, and a button is provided on the controller 7. The controller 7 is electrically connected to the shearing mechanism and the moving structure. The connection is used to control the shearing mechanism and the moving structure to shear and move. The rotating structure includes a driving component, a first connecting block 18 and a second connecting block 19. The driving component includes a first motor 17 and a rotating shaft. The bottom of the first motor 17 is fixedly connected to the top of the moving plate 14. The mounting blocks 4 are fixedly connected to each other through two first connecting blocks 18. The first motor 17 and the rotating shaft are located between the two first connecting blocks 18. The second connecting block 19 is fixedly connected to the rotating shaft. Both sides of the second connecting block 19 are fixedly connected to the mounting blocks 4 for connecting the two mounting blocks 4. The shearing mechanism includes mounting blocks 4, blades 5 and a first gear transmission structure. The mounting blocks 4 are connected to the top of the moving structure. The blades 5 are provided inside the mounting blocks 4 for cutting needles and guide tubes. The first gear transmission structure is provided on the blades 5 for driving the blades 5 to rotate.

[0022] The first gear transmission structure includes a second motor 8, a rotating rod 9, a first gear 10, a second gear 11, and a connecting rod 12. The top of the second motor 8 is fixedly connected to the inner wall of the top of the mounting block 4. The output end of the second motor 8 is fixedly connected to the rotating rod 9. The bottom end of the rotating rod 9 is fixedly connected to the blade 5. The top of the rotating rod 9 is fixedly connected to the first gear 10. The first gear 10 meshes with the second gear 11 on one side. The middle of the second gear 11 is fixedly connected to the connecting rod 12. The bottom end of the connecting rod 12 is fixedly connected to the blade 5. The bottom of the connecting rod 12 and the rotating rod 9 are rotatably connected to the inner wall of the bottom of the mounting block 4.

[0023] In the initial state, the rotating cover 3 is misaligned with the placement opening 6 at the top of the lid 2, allowing the rotating cover 3 and lid 2 to be completely closed. This isolates the internal moving structure and shearing mechanism of lid 2 from the external environment, preventing the exposure of internal sharp object fragments and the leakage of pathogens. It also prevents external debris from entering and affecting the mechanism's operation. By rotating the rotating cover 3 through the drive structure, the placement opening 6 at the top of lid 2 opens, aligning the rotating cover 3 with the placement opening 6 of lid 2, forming a channel for sharp object insertion, facilitating shearing. When a sharp object is inserted through the placement opening 6, the limiting structure clamps the sharp object, achieving radial fixation and preventing needle movement. The sharp instrument remains stable, improving cutting accuracy. Then, by pressing the button on the controller 7, the moving structure drives the top-connected rotating structure and the two sets of cutting mechanisms to move in a direction parallel to the bottom of the box cover 2 until the center of the blade 5 of the cutting mechanism is aligned with the part of the sharp instrument to be cut in the limiting structure. Then, the moving structure locks its position to prevent displacement during cutting. Then, the second motor 8 drives the rotating rod 9 and the first gear 10 to rotate. Through the action of the second gear 11 and the connecting rod 12, the blade 5 rotates towards the sharp instrument at the same time, thereby cutting the sharp instrument. The cut needle falls into the box 1 for collection.

[0024] When the cutting tool is a fine needle, the cutting mechanism near the limiting structure allows the blade 5 to cut directly. When the cutting tool is a thick metal needle with a harder material, the first motor 17 drives the rotating shaft to rotate the second connecting block 19. Since the two sides of the second connecting block 19 are fixedly connected to the mounting blocks 4 of the two cutting mechanisms, and the mounting blocks 4 maintain a relative distance through the two first connecting blocks 18, the rotating second connecting block 19 will drive the two cutting mechanisms to rotate synchronously around the rotating shaft, switching the cutting mechanism near the slider 15 with the cutting mechanism near the limiting structure, changing their positions, so that the blade 5 can adapt to tools of different diameters and hardness, thereby preventing the blade 5 from jamming and cutting failure during cutting, improving the service life of the blade 5, reducing the workload of medical staff, and adapting to the high-frequency and fast-paced operation scenarios in clinical practice.

[0025] like Figure 4 , Figure 5 , Figure 7As shown, the movable structure includes a fixed plate 13, a movable plate 14, a slider 15, and an electric push rod 16. One side of the fixed plate 13 is fixedly connected to the inner wall of the lid 2. The movable plate 14 is slidably connected to the outer side of the fixed plate 13. The slider 15 is fixedly connected to the top of the movable plate 14 and slidably connected to the bottom of the lid 2. The fixed plate 13 and the movable plate 14 are connected by the electric push rod 16. The slider 15 is located on both sides of the top of the movable plate 14. A mounting groove is provided on the movable plate 14 near the blade 5 for placing a catheter or needle. The movable plate 14 is located near the limiting structure... The side is arc-shaped. The fixed plate 13 has two fixed slots on the side near the moving plate 14. One end of the electric push rod 16 is fixedly connected to the fixed slot, and the other end is fixedly connected to the inner wall of the moving plate 14. There are two electric push rods 16, which are used to push the moving plate 14 to move. The first gear transmission structure is located inside the mounting block 4. The bottom of the mounting block 4 is rotatably connected to the top of the moving plate 14. One end of the blade 5 is located inside the mounting block 4 and is arranged in a V-shape. The blade 5 is in an open state. The other end of the blade 5 is located outside the mounting block 4 and is located on both sides of the mounting slot.

[0026] In the initial state, both electric push rods 16 are fully retracted, pulling the moving plate 14 to fit tightly against the outside of the fixed plate 13. The sliders 15 on both sides of the top of the moving plate 14 remain at the initial sliding position at the bottom of the box cover 2. After the needle with the guide tube is fixed in the placement port 6 by the limiting structure, the moving plate 14 is pushed by the electric push rod 16 to drive the shearing mechanism to move towards the limiting structure. The fixed end of the electric push rod 16 remains stable in the fixing groove of the fixed plate 13. The telescopic end of the electric push rod 16 pushes the moving plate 14 to move along the outside of the fixed plate 13. The sliders 15 on both sides of the top of the moving plate 14 slide synchronously along the bottom of the box cover 2. When the arc-shaped side of the moving plate 14 fits against the inner wall of the placement port 6, the guide tube can move to the center of the two blades 5 through the guiding action of the mounting groove, which facilitates the limiting of the guide tube and prevents the guide tube from shaking. Until the blade 5 of the shearing mechanism is precisely aligned with the part of the sharp object to be cut, the opening and closing of the figure-eight blade 5 through the first gear transmission structure achieves complete cutting of the sharp object. The cooperation between the mounting groove and the blade 5 ensures the stability of the shearing.

[0027] like Figures 2 to 3As shown, a drive structure is provided on the rotating cover 3 and the box cover 2. The drive structure includes a fixed block 20, a protective block 21, and a second gear transmission structure. The fixed block 20 is fixedly connected to the side of the box cover 2 away from the controller 7. The protective block 21 is fixedly connected to the box cover 2. The side of the protective block 21 away from the fixed block 20 is movably connected to the outside of the rotating cover 3. The second gear transmission structure is located inside the fixed block 20 and the protective block 21 to protect the second gear transmission structure. The second gear transmission structure includes a first transmission wheel 22, a second transmission wheel 23, a movable shaft, and a third motor 24. The first transmission wheel 22 is fixedly connected to the outside of the rotating cover 3 and is located inside the protective block 21. The second transmission wheel 23 is provided inside the fixed block 20. The movable shaft is fixedly connected to the middle of the second transmission wheel 23. The third motor 24 is fixedly connected to the bottom of the movable shaft. The third motor 24 is fixedly connected to the inner wall of the fixed block 20. Movable openings are provided on the sides of the fixed block 20 and the protective block 21. One side of the second transmission wheel 23 passes through the movable opening and meshes with the first gear 10.

[0028] When the third motor 24 starts, it drives the movable shaft to rotate. The second transmission wheel 23 in the middle of the movable shaft rotates synchronously. Since the second transmission wheel 23 passes through the movable opening and meshes with the first transmission wheel 22, and the first transmission wheel 22 is fixedly connected to the rotating cover 3, the rotation of the first transmission wheel 22 drives the second transmission wheel 23 and the rotating cover 3 to rotate. The rotating cover 3 rotates around the rotating groove on the top of the box cover 2, thereby enabling the rotating cover 3 to rotate automatically and realize the automatic opening and closing of the box cover 2, which facilitates the improvement of work efficiency. By connecting the movable opening of the fixed block 20 and the protective block 21, the stability of the meshing transmission of the first transmission wheel 22 and the second transmission wheel 23 is ensured, and the second gear transmission structure is protected to prevent damage caused by collision.

[0029] like Figure 2 , Figure 8 As shown, the limiting structure includes a placement block 25, a moving block 26, a spring 27, and a limiting plate 28. The placement block 25 is fixedly connected to the inner wall of the box cover 2. A through hole is opened in the middle of the placement block 25 for placing the catheter and needle to be cut. The moving block 26 is connected to both sides of the placement block 25 by the spring 27. The limiting plate 28 is fixedly connected to the top of the moving block 26. Grooves are opened on both sides of the placement block 25. The end of the moving block 26 near the placement block 25 is located in the groove, and the bottom of the moving block 26 is slidably connected to the inner wall of the groove. The spring 27 is located between the moving block 26 and the inner wall of the groove. The moving block 26, the spring 27, and the limiting plate 28 are symmetrically arranged with respect to the center of the placement block 25 for limiting the catheter from both sides. The limiting plate 28 is L-shaped and located at the top of the placement block 25. The end of the limiting plate 28 near the through hole is arc-shaped for fitting the outer wall of the catheter.

[0030] When medical staff insert the cutting instrument into the through hole, the moving block 26 slides outward along the groove of the placement block 25, the spring 27 is compressed and generates a reverse elastic force, which drives the limiting plate 28 to tightly fit the outer wall of the catheter from both sides, realizing the radial clamping and positioning of the sharp instrument. At the same time, the L-shaped structure of the limiting plate 28 forms a longitudinal limit on the top of the catheter to prevent excessive insertion. The limiting plate 28 can keep one end of the catheter perpendicular, so that the end of the sharp instrument to be cut remains stable, preventing the sharp instrument from easily shifting during insertion and affecting the cutting accuracy.

[0031] Working principle of this invention: Reference Figures 1 to 8 As shown, in the initial state, the rotating cover 3 and the placement opening 6 on the top of the box cover 2 are misaligned, so that the rotating cover 3 and the box cover 2 remain fully closed. When cutting is required, the button on the controller 7 is pressed to make the third motor 24 drive the movable shaft and the second transmission wheel 23 to rotate, which in turn makes the first transmission wheel 22 drive the rotating cover 3 to rotate in the rotating groove, so that the placement opening 6 on the rotating cover 3 coincides with the placement opening 6 on the box cover 2. Then, the cutting mechanism is adjusted according to the sharp object to be cut. When the sharp object to be cut is a tube with a fine needle, the moving block 26 and the limiting plate 28 are moved away from the placement block 25, so that the moving block 26 moves out of the groove, so that the spring 27 is stretched, and the two limiting plates 28 are moved away from each other. Then, the fine needle is placed at the bottom of the through hole, and the tube is located at the top of the through hole. Then, the limiting plate 28 is released, and the moving block 26 moves into the groove through the action of the spring 27, and drives the limiting plates 28 to move closer to each other, so that the limiting plate 28 can fit against the outer wall of the tube, clamp and position the tube, and keep the part of the tube to be cut vertical.

[0032] When the guide tube to be cut has a thick metal needle, the first motor 17 is started to drive the rotating shaft and the second connecting block 19 to rotate. Since the two sides of the second connecting block 19 are fixedly connected to the two mounting blocks 4, the rotation of the second connecting block 19 drives the two mounting blocks 4 and the first connecting block 18 to rotate simultaneously, switching the cutting mechanism near the slider 15 to the cutting mechanism near the limiting structure, and changing the position.

[0033] Then, the electric push rod 16 is activated to push the moving plate 14 to move the shearing mechanism towards the guide tube. The electric push rod 16 pushes the moving plate 14 to slide along the fixed plate 13. The slider 15 on the top of the moving plate 14 moves along the bottom of the box cover 2. When the arc-shaped side of the moving plate 14 is in contact with the inner wall of the box cover 2, the guide tube moves to the center of the two blades 5 through the guidance and limiting effect of the mounting groove. The second motor 8 is activated to drive the rotating rod 9 and the first gear 10 to rotate. Through meshing, the second gear 11 is driven to rotate in the opposite direction. The two blades 5 rotate from an open V-shape to a closed state towards the center along with the first gear 10 and the second gear 11, thereby cutting the sharp instrument. The cut needles fall into the box 1 for collection.

[0034] Once the sharp objects have been collected, press the button on the controller 7 to move the moving structure and shearing mechanism to their original positions. Press the button again to drive the rotating cover 3 to rotate, causing the rotating cover 3 to be misaligned with the placement opening of the box cover 2, thus closing the box cover and maintaining a seal.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
