Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to an automatic syringe needle separation device. Background Art

[0002] Syringes, essential tools for drug injection in clinical diagnosis and treatment, must strictly adhere to medical waste disposal regulations after use, with the needle and syringe separated and recycled. This practice aims to prevent discarded syringes from being mixed with general medical waste, prevent environmental pollution caused by the sharp nature of needles, and mitigate the risk of cross-transmission of diseases caused by residual blood and body fluids. It is a key step in the harmless and reduced disposal of medical waste.

[0003] However, the current clinical disassembly and recycling of discarded syringes is still mainly done manually, which poses significant safety hazards and efficiency shortcomings. On the one hand, medical staff need to directly contact sharp needle parts when manually pulling out or twisting needles, especially during peak batch processing periods. Due to the high repetitiveness of operations and decreased concentration, needle stick accidents are very likely to occur, and they face the risk of infection from blood-borne diseases such as hepatitis B and AIDS; on the other hand, the needles and syringes after manual disassembly are usually directly put into the same medical waste bin. Due to their irregular shapes, the two are piled up in a messy manner, resulting in the ineffective utilization of the internal space of the trash can. The presence of a large number of gaps makes the actual storage capacity of the trash can far lower than the rated capacity, and the trash can needs to be replaced frequently, which not only increases the extra workload of medical staff, but also increases the frequency and cost of medical waste collection and transportation, and increases the operating burden of medical facilities.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0019] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0020] See also Figures 1-8 In an embodiment of the present invention, an automatic syringe needle separation device includes a box body 1 and two door panels 2. The two door panels 2 are respectively installed on the left and right sides of the box body 1 through hinges. A disassembly mechanism 3 and a counter 4 are respectively installed on the left and right sides of the upper surface of the box body 1. The syringe and the needle are separated by the disassembly mechanism 3, and the counter 4 counts the number of syringes processed. A classification mechanism 5 is installed at the bottom of the inner cavity of the box body 1, and the syringe and the needle are classified and collected by the classification mechanism 5.

[0021] Furthermore, the disassembly mechanism 3 includes a frame 31 installed in the middle of the upper surface of the box body 1, and a limit box 32 is horizontally installed on the right inner wall of the frame 31. The inner cavity shape of the limit box 32 matches the outer shape of the syringe and is used for limiting the storage of the syringe. An opening and closing component 33 is horizontally installed in the inner cavity of the frame 31, and the opening and closing component 33 is used to control the opening and closing of the bottom of the limit box 32. A driving component 34 is installed on the right side wall of the frame 31, and the opening and closing component 33 is driven to move by the driving component 34. A stripping component 35 is installed on the left side wall of the limit box 32, and the stripping component 35 is used to separate the needle tube from the needle. Two left-right symmetrical guide plates 36 are installed in the middle of the lower surface of the frame 31. The guide plates 36 serve as a guiding and unloading role for the needle tube and the needle. The needle tube and the needle are stored separately on the sorting mechanism 5.

[0022] Furthermore, the opening and closing assembly 33 includes two sliding rods 331 installed on the inner wall of the frame 31 along the front-to-back direction, and baffles 332 are sleeved on the front and rear sides of the outer wall of the sliding rod 331. The bottom of the limit box 32 is closed by the baffle 332. A pin 333 is installed horizontally on the right side wall of the baffle 332. The pin 333 is a cylinder. The pin 333 slides smoothly in the guide groove 347 with the help of its own curved surface. A first rack 334 is installed at the left end of the baffle 332 on the rear side.

[0023] Furthermore, the driving assembly 34 includes a base 341 installed on the right side wall of the frame 31, a travel switch 342 electrically connected to the counter 4 is installed at the bottom of the right side wall of the base 341, and guide rods 343 are inserted on both the front and rear sides of the top of the base 341. The guide rods 343 restrict the moving direction of the lifting plate 346. The outer wall of the guide rod 343 is sleeved with a spring 344. A pressure plate 345 is installed on the top of the guide rod 343. The elastic force of the spring 344 is used to push the pressure plate 345 up. A lifting plate 346 is installed on the bottom of the guide rod 343. The outer wall of the lifting plate 346 is sleeved with a spring 344. The wall is provided with two front-to-back symmetrical guide grooves 347, and the pin 333 is inserted into the inner cavity of the guide groove 347. The guide grooves 347 are distributed on the outer wall of the lifting plate 346 and are inclined inward from top to bottom. When the lifting plate 346 is raised or lowered, the inclined surface of the guide groove 347 can squeeze the pin 333 inward or outward, thereby realizing the baffle 332 to move closer or further away; the elastic potential energy of the spring 344 always provides an upward reset thrust for the guide rod 343; and the guide groove 347 realizes the power conversion from the vertical movement of the lifting plate 346 to the horizontal movement of the pin 333.

[0024] Initial state: Under the elastic force of the spring 344 in the driving assembly 34, the lifting plate 346 is in a high position. At this time, the guide groove 347 produces an inward squeezing force on the pin 333, so that the four baffles 332 are close to each other and spliced ​​together, completely closing the bottom of the limit box 32. The first rack 334 is in the initial position and does not transmit light to the second gear 355 of the peeling assembly 35.

[0025] Opening process: When the medical staff presses down the pressure plate 345 of the driving assembly 34, the guide rod 343 drives the lifting plate 346 to overcome the elastic force of the spring 344 and move downward. Since the guide groove 347 is inclined inward from top to bottom, the inner wall of the guide groove 347 produces an outward thrust on the pin 333 during the descending process of the lifting plate 346, prompting the pin 333 to drive the baffle 332 to move to both sides along the slide rod 331. As the baffle 332 moves, the opening at the bottom of the limit box 32 gradually increases. At the same time, the rear baffle 332 drives the first rack 334 to move outward synchronously. The first rack 334 engages with the second gear 355 for transmission, providing rotational power for the rotating shaft 352 and the extrusion wheel 353 of the stripping assembly 35, thereby realizing the separation operation of the needle and the needle tube.

[0026] Resetting process: When the needle is separated from the syringe, the medical staff releases the pressure plate 345. Under the elastic force of the spring 344, the guide rod 343 drives the lifting plate 346 to move upward and reset. During the rising process of the lifting plate 346, the inner wall of the guide groove 347 generates an inward pulling force on the pin 333, prompting the pin 333 to drive the baffle 332 to move inward along the slide rod 331 until the four baffles 332 are re-spliced ​​to close the bottom of the limit box 32. At the same time, the first rack 334 and the subsequent baffle 332 are reset, waiting for the next syringe separation operation.

[0027] Furthermore, the stripping assembly 35 includes a support plate 351 horizontally mounted on the left side wall of the limit box 32, and a rotating shaft 352 is mounted on the front and rear sides of the upper surface of the support plate 351 through bearings. The upper and lower ends of the outer wall of the rotating shaft 352 are respectively mounted with an extrusion wheel 353 and a first gear 354, and the two first gears 354 are meshed and connected to allow the two rotating shafts 352 to rotate in opposite directions. The side wall of the extrusion wheel 353 is arc-shaped, and the surface is provided with anti-skid ridges. When the two extrusion wheels 353 rotate in opposite directions, the arc surface of the extrusion wheel 353 can gradually squeeze the needle head, and the anti-skid ridges increase the friction during extrusion. The force causes the needle to be moved from right to left and removed, and a second gear 355 meshing with the first rack 334 is installed at the bottom of the first gear 354 located on the front side, thereby realizing the linkage between the opening and closing component 33 and the stripping component 35; as the squeezing wheel 353 continues to rotate in the opposite direction, the traction force gradually becomes greater than the connection force between the needle and the needle tube, and the needle is slowly pulled to the left and gradually detached from the front end of the needle tube; when the needle is completely separated from the needle tube, the continuously rotating squeezing wheel 353 will transport the needle further to the left, thereby causing the needle to escape from the clamping range of the squeezing wheel 353 and fall.

[0028] Linkage triggering stage: When the baffle 332 in the opening and closing component 33 moves to both sides along the slide rod 331 under the action of the driving component 34, the first rack 334 at the left end of the rear baffle 332 moves synchronously in the horizontal direction (away from the limit box 32). Since the first rack 334 is engaged with the second gear 355, its horizontal movement drives the second gear 355 to rotate clockwise around its own axis.

[0029] Reverse transmission stage: when the second gear 355 rotates, it drives the front first gear 354 fixedly connected to it to rotate synchronously clockwise; because the front and rear first gears 354 are engaged with each other, the front first gear 354 drives the rear first gear 354 to rotate counterclockwise around its own axis; in this process, the two first gears 354 respectively drive the corresponding rotating shafts 352 to rotate synchronously, causing the front rotating shaft 352 and the extrusion wheel 353 to rotate clockwise, and the rear rotating shaft 352 and the extrusion wheel 353 to rotate counterclockwise, thereby realizing the reverse rotation of the two extrusion wheels 353.

[0030] Needle separation stage: At this time, the syringe needle in the limit box 32 has extended between the two extrusion wheels 353. The extrusion wheels 353 rotating in the opposite direction fit tightly against the outer wall of the needle through the curved side walls. The anti-slip edges on the surface are embedded in the tiny gap on the surface of the needle (or generate static friction with the outer wall of the needle), generating a continuous traction force to the left; as the extrusion wheel 353 continues to rotate, the traction force gradually increases. When the traction force is greater than the connection force between the needle and the syringe (usually 5-8N), the needle begins to slowly detach from the front end of the syringe. The detachment speed is controlled at 1-2mm / s to avoid the needle falling and position deviation due to excessive separation speed.

[0031] Needle transport and dropping stage: After the needle is completely separated from the syringe, the extrusion wheel 353 continues to rotate in the opposite direction, and continues to apply a leftward traction force to the needle to transport the needle horizontally to the left. When the needle is transported to completely out of the clamping range of the two extrusion wheels 353 (the transport distance is 10-15mm), the needle falls into the corresponding medical waste bin along the guide path of the sorting mechanism 5 under the action of its own gravity, completing the entire needle separation and collection process.

[0032] Reset stage: When the driving assembly 34 is reset (the spring 344 pushes the lifting plate 346 to rise), the first rack 334 of the opening and closing assembly 33 moves in the opposite direction along the horizontal direction (towards the limit box 32), driving the second gear 355 and the first gear 354 to rotate in the opposite direction, thereby restoring the rotating shaft 352 and the extruding wheel 353 to their initial positions, waiting for the next syringe separation operation.

[0033] Furthermore, the classification mechanism 5 includes a base 51 installed at the bottom of the inner cavity of the box body 1, and a central shaft 52 is vertically installed on both sides of the upper surface of the base 51. A plurality of stoppers 53 are installed on the upper surface of the base 51 along the circumference with the central shaft 52 as the center. A sleeve 54 is sleeved on the outer wall of the central shaft 52. The sleeve 54 is rotated around the central shaft 52 to realize the rotation and lifting bidirectional movement of the support plate 55. A support plate 55 is installed on the top of the sleeve 54. A storage groove 56 is opened on the upper surface of the support plate 55. The storage groove 56 is used to store medical waste bins. The side wall of the support plate 55 is circumferentially connected. A plurality of teeth 57 are installed on the upper surface of the base 51, and a cylinder 58 electrically connected to the limit switch 342 is installed on the front end of the upper surface of the base 51. A second rack 59 meshing with the teeth 57 is installed on the output end of the cylinder 58. The second rack 59 is driven back and forth by the cylinder 58, and the support plate 55 is rotated under the transmission condition of the second rack 59 and the teeth 57. A roller 510 is installed on the lower surface of the support plate 55, and the block 53 is triangular in shape. The roller 510 can roll on the inclined surface of the block 53 to change the height of the support plate 55, and the roller 510 supports the support plate 55.

[0034] Trigger start stage: When the lifting plate 346 in the disassembly mechanism 3 drops to the lowest point and triggers the limit switch 342, the limit switch 342 sends an electrical signal to the cylinder 58. The cylinder 58 is energized to start the output end to push the second rack 59 to move in the horizontal direction (towards the support plate 55).

[0035] Rotational transmission stage: During the movement of the second rack 59, its tooth surface engages with the teeth 57 on the side wall of the support plate 55, driving the support plate 55 to rotate clockwise around the central axis 52 (through the sleeve 54); at this time, the roller 510 on the lower surface of the support plate 55 rolls along the upper surface of the base 51, providing stable support for the rotation of the support plate 55 and reducing friction resistance.

[0036] Lifting and shaking stage: As the support plate 55 continues to rotate, when the roller 510 rolls to the position of the stopper 53, the roller 510 rolls upward along the triangular inclined surface of the stopper 53, pushing the support plate 55 to rise and fall upward along the central axis 52 through the sleeve 54 (the lifting height is consistent with the height of the stopper 53); when the roller 510 rolls over the apex of the stopper 53, it rolls downward along the inclined surface on the other side of the stopper 53, and the support plate 55 then falls back to its initial height; during the rotation process, the support plate 55 is periodically lifted and lowered through the cooperation of the roller 510 and the stopper 53, driving the medical waste bin in the storage slot 56 to shake synchronously, so that the needles or syringes in the bin are squeezed against each other due to the shaking, thereby reducing the gap, compacting the waste, and increasing the actual storage capacity of the bin.

[0037] Reset standby stage: When the piston of the cylinder 58 moves to the maximum stroke, the magnetic switch detects the piston position, and the output end of the cylinder 58 drives the second rack 59 to move in the opposite direction in the horizontal direction (away from the support plate 55), and through the meshing transmission of the teeth 57 and the second rack 59, drives the support plate 55 to rotate counterclockwise around the central axis 52 to reset; after the support plate 55 returns to its initial position, the cylinder 58 is powered off and stops working, and the classification mechanism 5 returns to the standby state, waiting for the next trigger signal of the travel switch 342.

[0038] Classification and collection coordination stage: During the operation of the classification mechanism 5, the needles separated by the disassembly mechanism 3 are guided by the left guide plate 36 and fall into the medical waste bin in the storage slot 56 on the left support plate 55; the separated syringes are guided by the right guide plate 36 and fall into the medical waste bin in the storage slot 56 on the right support plate 55, thereby realizing complete classification and storage of needles and syringes. At the same time, the utilization rate of the trash can is improved by shaking and compacting, and the frequency of replacing the trash can is reduced.

[0039] Working principle: Step 1: Place the discarded syringe in the limit box 32 and let the needle fall between the squeezing wheels 353. Press the pressure plate 345 downward, causing the guide rod 343 to drive the lifting plate 346 to descend. The guide groove 347 oblique surface squeezes the pin 333 outward, and the two baffles 332 gradually move away from each other. Under the movement of the first rack 334, the second gear 355 rotates. The two squeezing wheels 353 rotate in opposite directions through the two first gears 354. The squeezing wheels 353 roll the needle from right to left, and the needle is pulled out of the syringe. It falls into the medical waste bin on the left under the guidance of the guide plate 36, and the baffle 332 opens the bottom of the limit box 32. The syringe falls under its own gravity and enters the medical waste bin on the right, realizing automatic separation of the syringe. Step 2: When the lifting plate 346 touches the travel switch 342 during the descent process, the counter 4 counts and calculates the number of syringes recovered. At the same time, the cylinder 58 pushes the second rack 59 to move back and forth. Under the transmission condition of the second rack 59 and the teeth 57, the support plate 55 rotates with the central axis 52 as the center of the circle, and the roller 510 rolls on the base 51. When passing the stopper 53, the roller 510 rolls along the inclined surface of the stopper 53. The support plate 55 rotates and shakes up and down, so that the needles and syringes move, the gap between them is reduced, and the space occupied by the needles and syringes is reduced, so that the medical waste bin can store more needles and syringes, thereby improving the utilization rate of the medical waste bin. Step three, when it is necessary to reset the extrusion wheel 353 and the baffle 332, release the pressure plate 36, and the spring 344 pushes the lifting plate 346 upward under its own elastic force. The guide groove 347 bevels inward to squeeze the pin 333, and the two baffles 332 approach each other and reset. Under the transmission conditions of the first rack 334 and the second gear 355, the extrusion wheel 353 rotates and resets, preparing for the next syringe separation.

[0040] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
