Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an automatic syringe needle separation device. Background Technology

[0002] Syringes are indispensable drug injection tools in clinical diagnosis and treatment. After use, they must be disposed of in strict accordance with medical waste disposal regulations, and the needle and syringe must be separated and recycled. The core purpose of this operation is to prevent the waste syringe from being mixed with ordinary medical waste, to prevent environmental pollution caused by the sharpness of the needle, and to block the risk of cross-infection of diseases caused by blood and body fluid residues. It is a key step in the harmless and reduced-volume treatment of medical waste.

[0003] However, the disassembly and recycling of used syringes in clinical practice is still mainly done manually, which poses significant safety hazards and inefficiencies. On the one hand, when medical staff manually remove or twist the needles, they need to directly contact the sharp needle parts. Especially during peak processing times, due to the high repetition of the operation and decreased concentration, needle stick injuries are very likely to occur, leading to the risk of infection with bloodborne diseases such as hepatitis B and HIV. On the other hand, the manually disassembled needles and syringes are usually directly put into the same medical waste bin. Due to their irregular shapes, they are piled up haphazardly, resulting in the ineffective use of the bin's internal space. The presence of many gaps means that the actual storage capacity of the bin is far below the rated capacity, requiring frequent bin replacements. This not only increases the extra workload of medical staff but also increases the frequency and cost of medical waste collection and transportation, exacerbating the operational burden on medical facilities. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic syringe needle separation device to solve the problems mentioned in the background art, such as the inability to automatically separate the needle from the syringe tube and the low utilization rate of medical waste bins.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic syringe needle separation device, comprising a housing and two door panels, the two door panels being hinged to the left and right sides of the housing respectively, a disassembly mechanism and a counter being installed on the left and right sides of the upper surface of the housing respectively, the disassembly mechanism separating the syringe tube from the needle tip, the counter counting the number of syringes processed, and a sorting mechanism being installed at the bottom of the inner cavity of the housing for sorting and collecting the syringe tubes and needle tips.

[0006] Preferably, the disassembly mechanism includes a frame installed in the middle of the upper surface of the housing. A limiting box is installed horizontally on the right inner wall of the frame. The inner cavity of the limiting box matches the shape of the syringe and is used for limiting and storing the syringe. An opening and closing component is installed horizontally in the inner cavity of the frame. The opening and closing component controls the opening and closing of the bottom of the limiting box. A driving component is installed on the right side wall of the frame. The driving component drives the opening and closing component to move. A peeling component is installed on the left side wall of the limiting box. The peeling component separates the needle tube from the needle tip. Two symmetrical guide plates are installed in the middle of the lower surface of the frame. The guide plates guide the needle tube and needle tip for feeding. The needle tube and needle tip are stored separately on the sorting mechanism. The driving component provides working power to the opening and closing component. Under the linkage of the opening and closing component and the peeling component, the needle tube and needle tip are automatically separated and fed.

[0007] Preferably, the opening and closing assembly includes two sliding rods installed on the inner wall of the frame in the front-back direction. Baffles are sleeved on both the front and back sides of the outer wall of the sliding rods to close the bottom of the limiting box. A pin is installed laterally on the right side wall of the baffle, and a first rack is installed on the left end of the baffle located on the rear side. The baffle moves inward or outward to close and open the limiting box, thereby limiting and feeding the needle tube.

[0008] Preferably, the drive assembly includes a base mounted on the right side wall of the frame. A limit switch electrically connected to the counter is installed at the bottom of the right side wall of the base. Guide rods are inserted into the front and rear sides of the top of the base. Springs are sleeved on the outer walls of the guide rods. A pressure plate is installed at the top of the guide rods. The spring force pushes the pressure plate to rise. A lifting plate is installed at the bottom of the guide rods. Two symmetrical guide grooves are opened on the outer wall of the lifting plate, and pins are inserted into the inner cavities of the guide grooves. The tilt angle of the guide grooves changes the direction of the pin movement, which serves as the power for the two baffles to move closer or further apart.

[0009] Preferably, the guide grooves are distributed on the outer wall of the lifting plate from top to bottom and inward.

[0010] Preferably, the peeling assembly includes a support plate horizontally mounted on the left side wall of the limiting box. The upper surface of the support plate is equipped with a rotating shaft on both the front and rear sides via bearings. The upper and lower ends of the outer wall of the rotating shaft are respectively equipped with a squeezing wheel and a first gear, and the two first gears are meshed together. A second gear that meshes with a first rack is installed at the bottom of the first gear located on the front side. The rotation time interval of the two squeezing wheels gradually decreases, which can pull the needle to the left to move and separate from the needle tube.

[0011] Preferably, the sidewall of the extrusion wheel is arc-shaped and has anti-slip ridges on its surface.

[0012] Preferably, the sorting mechanism includes a base installed at the bottom of the inner cavity of the box. A central shaft is vertically installed on both the left and right sides of the upper surface of the base. Several blocks are installed circumferentially around the central shafts on the upper surface of the base. A sleeve is fitted onto the outer wall of the central shafts, and a tray is installed at the top of the sleeve. A storage slot is formed on the upper surface of the tray for storing medical waste bins. Several teeth are installed circumferentially on the sidewalls of the tray. A cylinder electrically connected to a limit switch is installed at the front end of the upper surface of the base. A second rack is installed at the output end of the cylinder and meshes with the teeth. The cylinder drives the second rack to move back and forth, causing the tray to rotate under the transmission between the second rack and the teeth. Rollers are installed on the lower surface of the tray to support it. The rotation of the tray is achieved by the second rack engaging with the teeth, and the rollers engaging with the blocks to raise and lower the tray, causing the medical waste bins to fall repeatedly, bringing needles and syringes closer together, reducing the space occupied by the medical waste bins, and increasing storage capacity.

[0013] As a further embodiment of the present invention, the stop block is triangular in shape.

[0014] Compared with the prior art, the beneficial effects of the embodiments of the present invention are:

[0015] 1. This invention uses a pressure plate to press down on a sliding rod, causing the lifting plate to descend. With the cooperation of the guide groove and pin, the baffle gradually moves away. Through the transmission of the first rack and the second gear, the two extrusion wheels rotate in opposite directions. The extrusion wheels remove the needle from the needle tube. Then, the baffle opens the bottom of the limiting box. Under the guidance of the guide plate, the needle and needle tube are stored separately, realizing the automatic separation of the needle and needle tube and avoiding needle puncture accidents.

[0016] 2. This invention triggers a limit switch by lowering a lifting plate, uses a counter to count the number of syringes used, pushes a second rack to move back and forth, and the second rack and teeth drive the tray to rotate. The rollers roll along the base and the stop, causing the medical waste bin to bounce up and down, compacting the needles and syringes inside. This effectively utilizes the internal space of the waste bin, improving its utilization rate. It eliminates the need for frequent waste bin replacements, reducing the extra workload of medical staff and increasing the frequency and cost of medical waste collection and transportation, thus alleviating the operational burden of medical facilities.

[0026] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0027] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] Please see Figures 1-8 In this embodiment of the invention, an automatic syringe needle separation device includes a housing 1 and two door panels 2. The two door panels 2 are respectively installed on the left and right sides of the housing 1 by hinges. A disassembly mechanism 3 and a counter 4 are respectively installed on the left and right sides of the upper surface of the housing 1. The disassembly mechanism 3 separates the syringe tube from the needle, and the counter 4 counts the number of syringes processed. A sorting mechanism 5 is installed at the bottom of the inner cavity of the housing 1 to sort and collect the syringe tube and needle.

[0029] Furthermore, the disassembly mechanism 3 includes a frame 31 installed in the middle of the upper surface of the housing 1. A limiting box 32 is installed horizontally on the right inner wall of the frame 31. The inner cavity shape of the limiting box 32 matches the shape of the syringe and is used for limiting and storing the syringe. An opening and closing component 33 is installed horizontally in the inner cavity of the frame 31. The opening and closing component 33 is used to control the opening and closing of the bottom of the limiting box 32. A driving component 34 is installed on the right side wall of the frame 31. The driving component 34 drives the opening and closing component 33 to move. A peeling component 35 is installed on the left side wall of the limiting box 32. The peeling component 35 is used to separate the needle tube and the needle tip. Two symmetrical guide plates 36 are installed in the middle of the lower surface of the frame 31. The guide plates 36 serve to guide the needle tube and the needle tip for feeding. The needle tube and the needle tip are stored separately on the sorting mechanism 5.

[0030] Furthermore, the opening and closing assembly 33 includes two sliding rods 331 installed on the inner wall of the frame 31 in the front-back direction. Baffles 332 are sleeved on both the front and back sides of the outer wall of the sliding rods 331, and the bottom of the limiting box 32 is closed by the baffles 332. A pin 333 is installed laterally on the right side wall of the baffle 332. The pin 333 is a cylinder and slides smoothly in the guide groove 347 by means of its own curved surface. A first rack 334 is installed on the left end of the baffle 332 located on the rear side.

[0031] Furthermore, the drive assembly 34 includes a base 341 mounted on the right side wall of the frame 31. A limit switch 342 electrically connected to the counter 4 is installed at the bottom of the right side wall of the base 341. Guide rods 343 are inserted into the front and rear sides of the top of the base 341, constraining the movement direction of the lifting plate 346. A spring 344 is sleeved on the outer wall of the guide rod 343. A pressure plate 345 is installed at the top of the guide rod 343, and the spring force of the spring 344 pushes the pressure plate 345 to rise. The lifting plate 346 is installed at the bottom of the guide rod 343. The wall has two 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 from top to bottom and inward. When the lifting plate 346 rises and falls, the inclined surface of the guide groove 347 can press the pin 333 inward or outward, thereby making the baffle 332 move closer or further away. The elastic potential energy of the spring 344 always provides an upward reset thrust for the guide rod 343. 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.

[0032] Initial state: Under the elastic force of spring 344 in drive assembly 34, lifting plate 346 is in a high position. At this time, guide groove 347 exerts inward squeezing force on pin 333, causing four baffles 332 to approach each other and splice together, completely sealing the bottom of limit box 32. First rack 334 is in the initial position and does not drive with second gear 355 of peeling assembly 35.

[0033] Opening process: When medical staff press down the pressure plate 345 of the drive assembly 34, the guide rod 343 drives the lifting plate 346 to move downward against the elastic force of the spring 344. Since the guide groove 347 is inclined inward from top to bottom, the inner wall of the guide groove 347 generates an outward pushing force on the pin 333 during the descent of the lifting plate 346, causing 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 limiting 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 meshes with the second gear 355 to provide rotational power for the rotating shaft 352 and the squeezing wheel 353 of the stripping assembly 35, realizing the separation operation of the needle and the needle tube.

[0034] Reset process: After 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 rise of the lifting plate 346, the inner wall of the guide groove 347 generates an inward pulling force on the pin 333, causing the pin 333 to drive the baffle 332 to move inward along the slide rod 331 until the four baffles 332 are reassembled to close the bottom of the limiting box 32. At the same time, the first rack 334 resets the subsequent side baffle 332, waiting for the next syringe separation operation.

[0035] Furthermore, the peeling assembly 35 includes a support plate 351 horizontally mounted on the left side wall of the limiting box 32. A rotating shaft 352 is mounted on the front and rear sides of the upper surface of the support plate 351 via bearings. A pressing wheel 353 and a first gear 354 are respectively mounted on the upper and lower ends of the outer wall of the rotating shaft 352, and the two first gears 354 are meshed together, allowing the two rotating shafts 352 to rotate in opposite directions. The side wall of the pressing wheel 353 is arc-shaped, and its surface is provided with anti-slip ridges. When the two pressing wheels 353 rotate in opposite directions, the arc-shaped surface of the pressing wheel 353 can gradually press the needle tip, and the anti-slip ridges increase friction during pressing. Force enables the needle to move from right to left and be removed. The bottom of the first gear 354 located on the front side is equipped with a second gear 355 that meshes with the first rack 334, realizing the linkage between the opening and closing component 33 and the peeling component 35. As the squeezing wheel 353 continues to rotate in the opposite direction, the traction force gradually exceeds the connection force between the needle and the needle tube, and the needle is slowly pulled to the left, gradually separating 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 further transport the needle to the left, thereby causing the needle to fall out of the clamping range of the squeezing wheel 353.

[0036] Linkage triggering stage: When the baffle 332 in the opening and closing assembly 33 moves to both sides along the slide bar 331 under the action of the drive assembly 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 meshes with the second gear 355, its horizontal movement drives the second gear 355 to rotate clockwise around its own axis.

[0037] Reverse transmission stage: When the second gear 355 rotates, it drives the front first gear 354, which is fixedly connected to it, to rotate synchronously clockwise; because the front and rear first gears 354 mesh with each other, the front first gear 354 drives the rear first gear 354 to rotate counterclockwise around its own axis; during this process, the two first gears 354 respectively drive the corresponding rotating shafts 352 to rotate synchronously, so that the front rotating shaft 352 and the extrusion wheel 353 rotate clockwise, and the rear rotating shaft 352 and the extrusion wheel 353 rotate counterclockwise, realizing the reverse rotation of the two extrusion wheels 353.

[0038] Needle separation stage: At this time, the syringe needle in the limiting box 32 has extended between the two squeezing rollers 353. The squeezing rollers 353 rotating in opposite directions are tightly attached to the outer wall of the needle through the arc-shaped sidewall. The anti-slip ridges on the surface are embedded in the tiny gaps 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 squeezing rollers 353 continue 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 off and shifting position due to excessive separation speed.

[0039] Needle delivery and drop stage: After the needle is completely separated from the syringe, the reverse rotation of the squeezing wheel 353 continues, applying a leftward traction force to deliver the needle horizontally to the left. When the needle is completely removed from the clamping range of the two squeezing wheels 353 (the delivery distance is 10-15mm), the needle falls into the corresponding medical waste bin along the guide path of the sorting mechanism 5 under its own gravity, completing the entire needle separation and collection process.

[0040] Reset phase: When the drive 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 in the horizontal direction (near 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 squeezing wheel 353 to their initial positions, waiting for the next syringe separation operation.

[0041] Furthermore, the sorting mechanism 5 includes a base 51 installed at the bottom of the inner cavity of the box 1. A central shaft 52 is vertically installed on both the left and right sides of the upper surface of the base 51. Several stops 53 are installed circumferentially around the central shaft 52 on the upper surface of the base 51. A sleeve 54 is fitted onto the outer wall of the central shaft 52. The sleeve 54 rotates around the central shaft 52, enabling the tray 55 to rotate and move in both directions. A tray 55 is installed at the top of the sleeve 54. A storage slot 56 is formed on the upper surface of the tray 55 for storing medical waste bins. The side walls of the tray 55 are circumferentially... A cylinder 58 electrically connected to a limit switch 342 is installed on the front end of the upper surface of the base 51, which is equipped with several teeth 57. A second rack 59 is installed at the output end of the cylinder 58 and meshes with the teeth 57. The cylinder 58 drives 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 is rotated. A roller 510 is installed on the lower surface of the support plate 55. The stop block 53 is triangular in shape. The roller 510 can roll on the inclined surface of the stop block 53 to change the height of the support plate 55 and support the support plate 55.

[0042] Triggering start-up phase: When the lifting plate 346 in the disassembly mechanism 3 descends to the lowest point and triggers the limit switch 342, the limit switch 342 sends an electrical signal to the cylinder 58, and the cylinder 58 is energized and starts to push the second rack 59 to move in the horizontal direction (near the support plate 55).

[0043] Rotational transmission stage: During the movement of the second rack 59, its tooth surface meshes 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 frictional resistance.

[0044] Lifting and shaking stage: As the tray 55 continues to rotate, when the roller 510 rolls to the position of the stop 53, the roller 510 rolls upward along the triangular slope of the stop 53, pushing the tray 55 to rise and fall upward along the central axis 52 through the sleeve 54 (the lifting height is the same as the height of the stop 53); when the roller 510 rolls past the apex of the stop 53, it rolls downward along the other side slope of the stop 53, and the tray 55 falls back to the initial height; during the rotation, the tray 55 achieves periodic up and down lifting through the cooperation of the roller 510 and the stop 53, causing the medical waste bin in the storage slot 56 to shake synchronously, so that the needles or syringes in the bin squeeze each other due to the shaking, reducing the gaps, compacting the waste, and increasing the actual storage capacity of the waste bin.

[0045] Reset standby stage: When the piston of cylinder 58 moves to its maximum stroke, the magnetic switch detects the piston position, and the output end of cylinder 58 drives the second rack 59 to move in the opposite direction in the horizontal direction (away from the support plate 55). Through the meshing transmission between the teeth 57 and the second rack 59, the support plate 55 is driven to rotate counterclockwise around the central axis 52 to reset. After the support plate 55 returns to the initial position, cylinder 58 is de-energized and stops working, and the sorting mechanism 5 returns to the standby state, waiting for the trigger signal of the limit switch 342 next time.

[0046] 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 tray 55; the separated needle tubes are guided by the right guide plate 36 and fall into the medical waste bin in the storage slot 56 on the right tray 55, realizing the complete classification and storage of needles and needle tubes. At the same time, the utilization rate of the waste bin is improved by shaking and compaction, and the frequency of waste bin replacement is reduced.

[0047] Working principle:

[0048] Step 1: The discarded syringe is placed in the limiting box 32, with the needle falling between the squeezing wheels 353. The pressure plate 345 is pressed down, causing the guide rod 343 to drive the lifting plate 346 to descend. The guide groove 347 squeezes the pin 333 outward at an angle, and the two baffles 332 gradually move away. Under the condition of the movement of the first rack 334, the second gear 355 rotates. Through the transmission of the two first gears 354, the two squeezing wheels 353 rotate in opposite directions. The squeezing wheels 353 roll the needle from right to left, and the needle is pulled off the needle tube. Guided by the guide plate 36, it falls into the medical waste bin on the left. The baffle 332 opens the bottom of the limiting box 32, and the needle tube falls under its own weight and enters the medical waste bin on the right, realizing the automatic separation of the syringe.

[0049] Step 2: When the lifting plate 346 touches the limit switch 342 during its descent, the counter 4 counts and records 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 of the second rack 59 and the teeth 57, the support plate 55 rotates around the central axis 52. The roller 510 rolls on the base 51. When it passes the stop 53, the roller 510 rolls along the inclined surface of the stop 53. While the support plate 55 rotates, it shakes up and down, causing the needle and syringe to move, reducing the gap and the space occupied by the needle and syringe. This increases the storage capacity of the medical waste bin for needles and syringes, improving the utilization rate of the medical waste bin.

[0050] Step 3: When it is necessary to reset the squeezing wheel 353 and the baffle 332, release the pressure plate 345. The spring 344 pushes the lifting plate 346 upward under its own elastic force. The guide groove 347 squeezes the pin 333 inward at an angle. The two baffles 332 move closer to each other and reset. Under the transmission of the first rack 334 and the second gear 355, the squeezing wheel 353 rotates and resets, preparing for the next syringe separation.

[0051] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
