Description

Technical Field

[0001] This application relates to the field of medical equipment technology, specifically to a fully automated waste medical needle disposal device. Background Technology

[0002] In medical diagnosis and treatment activities, medical devices with metal needles, such as syringes and infusion sets, are used in large quantities. As high-risk medical sharps, the proper handling of discarded needles is directly related to the occupational safety of medical staff and public health safety. Discarded needles and other sharps need to be collected separately and disposed of in a harmless manner to avoid secondary injuries caused by exposed sharp parts.

[0003] Currently, there are still many hidden dangers in the way medical staff handle discarded needles: when separating needles from syringes manually, the probability of hands coming into direct contact with sharp objects is extremely high, which can easily lead to needlestick injuries and thus increase the risk of bloodborne disease infection; even when using simple separation tools, manual assistance is still required to pick and collect the needles, which is a cumbersome and inefficient process.

[0004] While some automated processing devices have emerged in the prior art, such as the waste syringe processing device with application number 202410343002.4, which can automatically separate the needle from the syringe barrel, it does not thoroughly passivate the sharpness of the needle, leaving the separated needle with a risk of secondary injury. The closed-loop needle processing device with publication number CN112891684B achieves safety by hiding the needle tip within the syringe plug, but this structure has poor adaptability to needle sizes and does not address the disinfection requirements during needle processing. Furthermore, existing devices generally suffer from fragmented processes; the separation, passivation, disinfection, and collection stages lack coordinated design, affecting processing efficiency and increasing the risk of contact. Summary of the Invention

[0005] To overcome the problems existing in the prior art, the purpose of this application is to provide a fully automated waste medical needle processing device. It adopts a clamping and fixing, lifting and lifting integrated hot pressing and winding structure, combined with the coordinated control of the process of heating and softening, flattening and shaping, winding into a ball, disinfection and peeling. This solves the pain points of existing devices such as easy breakage of needles, incomplete blunting of sharp parts, lack of disinfection function, poor adaptability and the need for manual intervention. It realizes contactless automated processing of waste needles, effective killing of pathogenic microorganisms and safe collection of medical waste.

[0006] The objective of this application is achieved through the following technical solution: A fully automatic waste medical needle disposal device includes a disposal body, the top of which is provided with a fixing component for holding a syringe, and the interior is provided with a lifting slide that moves vertically, the lifting slide integrating a heat pressing component and a needle winding component. The hot pressing assembly is used to heat, soften, and flatten the needle tip, and the needle winding assembly is used to wind the flattened needle tip into a ball. The needle winding assembly is provided with a sterilization component and a peeling component. It also includes a control device, which is used to drive the lifting slide to rise and fall, and coordinate the heating and flattening action of the hot pressing assembly, the winding action of the needle winding assembly, the disinfection action of the synchronous disinfection component, and the separation action of the peeling component.

[0007] Preferably, the fixing component includes a cylinder fixed to the top of the processing body, the inner wall of the cylinder having a plurality of retractable connectors arranged in a circular array, and the bottom surface of the cylinder having an insertion hole for the needle to be inserted into the center; the connectors are hollow and have an opening on one side facing the central axis of the insertion hole, and the connectors have a spring and a slidably connected fixing block inside.

[0008] Preferably, the top open end of the cylinder is fitted with a rotatable and detachable fixed top cover, which is threadedly engaged with the top of the cylinder.

[0009] Preferably, the hot pressing assembly includes a hot pressing fixing block and a heating block arranged opposite to each other, and a driving cylinder for driving the two to move in opposite directions; the heating block has an integrally formed positioning block on the side facing the hot pressing fixing block, and a heating element is embedded in the positioning block, the heating element being electrically connected to a temperature controller; the hot pressing fixing block has a positioning groove adapted to the positioning block on the side facing the heating block.

[0010] Preferably, the needle winding assembly includes a needle winding mounting base, which is fixedly connected to a lifting slide. The needle winding mounting base has a through groove, and a forked needle winding rod is horizontally arranged in the groove. A first servo motor that drives the forked needle winding rod to rotate is provided on one side of the needle winding mounting base. The part of the forked needle winding rod away from the first servo motor has a forked gap for the needle tip to extend into.

[0011] Preferably, the synchronous disinfection component is a disinfection ultraviolet lamp, which is fixed to the inner side of the through groove and the irradiation direction is towards the rod area of ​​the forked needle winding rod.

[0012] Preferably, the peeling element is a needle peeling ring sleeved on the bifurcated needle coiling rod, and the needle coiling assembly further includes a driving structure for driving the needle peeling ring to move axially.

[0013] Preferably, the driving structure includes a second servo motor fixed to the side wall of the needle winding seat, a lead screw parallel to the forked needle winding rod, and a lead screw slider threaded with the lead screw; the second servo motor drives the lead screw to rotate through a transmission gear set, and the lead screw slider is fixedly connected to the needle stripping ring through a connecting rod.

[0014] Preferably, the lower part of the processing body has a pick-and-place opening, and a needle collection box is slidably disposed in the pick-and-place opening. The needle collection box is located directly below the needle winding assembly, and the outer wall of the needle collection box is provided with a handle for easy pulling.

[0015] Preferably, the drive cylinder has two cylinders arranged symmetrically, which are fixedly connected to the hot pressing block and the heating block respectively, for driving the two to move synchronously in opposite directions.

[0016] Compared with the prior art, this application has the following advantages: 1. This application adopts a combined processing method of heating and softening, flattening and winding into a ball. The needle is heated and softened by a hot pressing component and then flattened, which significantly reduces the brittleness of the needle metal and avoids the breakage problem caused by traditional direct winding. After flattening, the needle is wound into a tight metal ball by a forked needle winding rod, avoiding secondary damage caused by the needle and fragments.

[0017] 2. The control device coordinates the coordinated actions of the lifting slide, the hot pressing assembly, and the needle coiling assembly to automate the process from syringe fixing, needle handling to collection. It eliminates the need for medical staff to manually separate, pick, or peel the needles, completely avoiding the risk of infection from hand contact with the needles. It is especially suitable for high-frequency needle use scenarios such as hospital hematology departments and emergency departments.

[0018] 3. The needle winding assembly has a built-in ultraviolet disinfection lamp that performs ultraviolet disinfection simultaneously during the needle winding and passivation process. This effectively kills pathogenic microorganisms attached to the needle surface. The disinfection and winding processes are carried out simultaneously, eliminating the need for additional processing steps. This ensures the disinfection effect without affecting the overall processing efficiency, further reducing the risk of infection from medical waste.

[0019] 4. The lifting slide integrates the hot pressing component and the needle winding component, realizing synchronous lifting of the two components to ensure alignment during needle processing and simplify the internal transmission structure of the device. The automatic stripping component of the needle winding component uses a servo motor, lead screw and slider drive structure to strip the needle clumps. Compared with the traditional mechanical impact stripping, it avoids the scattering or fragmentation of needle clumps, further improving the reliability of processing. In addition, a sliding needle collection box is set at the bottom for easy centralized collection and transportation, reducing the operational intensity of medical waste disposal.

Detailed Implementation

[0022] To enable those skilled in the art to better understand this application, the technical solutions of this application will be clearly and completely described below with reference to embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The following detailed explanation of specific implementation methods further illustrates this application: See Figure 1In this embodiment, the fully automated waste medical needle disposal device uses a disposal body 1 as its core mounting carrier. The disposal body 1 has a cylindrical hollow structure with a pick-and-place opening on its lower side wall. The inner side wall of the pick-and-place opening has two parallel sliding grooves (not shown in the figure) for installing the needle collection box 12. A cylindrical fixing component 5 is fixed to the top of the disposal body 1, and its axis coincides with the vertical center line of the disposal body 1. A fixed top cover 11 is provided at the top opening of the cylinder. The fixed top cover 11 is a circular plastic cover with an inner diameter that matches the outer diameter of the cylinder. Its inner side wall has internal threads, and the outer side wall of the top of the cylinder has matching external threads. The fixed top cover 11 is detachably connected to the cylinder through threaded engagement.

[0024] See Figure 2 A lifting slide 3 is vertically fixed on one side of the inner wall of the processing body 1. The guide rail of the lifting slide 3 is arranged in the vertical direction, and its lifting slider is fixed to the side of the needle mounting seat 44, so that the needle mounting seat 44 can be raised and lowered synchronously with the lifting slider.

[0025] See Figure 1 The control device 6 is fixed to the outer wall of the processing body 1. The control device 6 is electrically connected to the lifting slide 3, the first servo motor 41, the second servo motor 42, the drive cylinder 23, the temperature controller 24, and the disinfection ultraviolet lamp 43 respectively through wires (not shown in the figure). The wires are introduced into the interior through the wire holes reserved in the side wall of the processing body 1, and rubber sealing sleeves are provided at the wire holes.

[0026] See Figure 7 The inner wall of the fixing component 5 has three connectors 51 arranged in a ring array. The three connectors 51 are evenly distributed circumferentially along the inner wall of the cylinder. Each connector 51 is a hollow cuboid structure, with its outer side wall fixed to the inner wall of the cylinder. Each connector 51 has a rectangular opening on the side facing the central axis of the insertion hole 52. (See reference...) Figure 8 Inside the connector 51, a spring 512 and a fixing block 511 are horizontally arranged. The spring 512 is a cylindrical helical compression spring, with one end fixed to the inner side wall of the connector 51 and the other end fixed to one end of the fixing block 511. The fixing block 511 has a trapezoidal structure, and its bottom is provided with a slider that matches the sliding groove on the bottom surface of the connector 51. The slider slides in the sliding groove, allowing the fixing block 511 to extend and retract along the opening direction. The insertion hole 52 is a circular through hole located at the center of the bottom surface of the cylinder.

[0027] See Figure 6The hot-pressing assembly 2 is positioned above the needle mounting base 44. Two drive cylinders 23 are horizontally fixed to the inner wall of the processing body 1 via a mounting bracket. The drive cylinders 23 are electric telescopic cylinders, and the two drive cylinders 23 are arranged symmetrically. The output shaft of the left drive cylinder 23 is fixed to the side of the hot-pressing fixing block 21, and the output shaft of the right drive cylinder 23 is fixed to the side of the heating block 22. A positioning block 221 is integrally formed on the side of the heating block 22 facing the hot-pressing fixing block 21. The positioning block 221 has a V-shaped structure. A positioning groove 211 adapted to the positioning block 221 is opened on the side of the hot-pressing fixing block 21 facing the heating block 22. The depth and width of the positioning groove 211 are consistent with the height and thickness of the positioning block 221, ensuring that the positioning block 221 can be completely embedded in the positioning groove 211. A heating element (not shown in the figure) is embedded inside the positioning block 221. The heating element is a nickel-chromium alloy heating wire. The heating wire is electrically connected to a temperature controller 24 via a high-temperature resistant wire. The temperature controller 24 is fixed to the mounting bracket.

[0028] See Figure 4 and Figure 5 The needle mounting base 44 of the needle winding assembly 4 is a rectangular stainless steel block with a through groove 441 on its top surface. The through groove 441 is a rectangular through hole that passes through the needle mounting base 44. A forked needle winding rod 411 is horizontally arranged in the through groove 441. The left end of the forked needle winding rod 411 is rotatably connected to the left inner wall of the through groove 441 via a deep groove ball bearing (not shown in the figure), and is fixedly connected to the output shaft of the first servo motor 41 through the left inner wall. The first servo motor 41 is fixed to the left side of the needle mounting base 44 via a motor bracket. A forked gap is formed on the right end of the forked needle winding rod 411 away from the first servo motor 41. The forked gap is a strip-shaped notch along the length of the rod, and the edges of the notch are rounded. A disinfection UV lamp 43 is fixed on the inner wall of the through groove 441. The disinfection UV lamp 43 is a UV-CLED with a power of 5W and a wavelength of 254nm. The irradiation direction is towards the middle area of ​​the forked needle coiling rod 411, and the irradiation angle covers the entire rod of the forked needle coiling rod 411.

[0029] See Figure 4A second servo motor 42 is fixed to the right side of the needle winding mounting base 44. The second servo motor 42 is the same model as the first servo motor 41 and is fixed to the needle winding mounting base 44 by a motor bracket. The output shaft of the second servo motor 42 is fixed with the driving gear of the transmission gear set 421. The driven gear of the transmission gear set 421 is fixed to one end of the lead screw 422, and the driving gear and the driven gear mesh for transmission. A sliding groove is opened on one side of the inner wall of the through groove 441. The two ends of the lead screw 422 are rotatably connected to the inner wall of the sliding groove through deep groove ball bearings. The lead screw 422 is arranged parallel to the forked needle winding rod 411. A lead screw slider 423 is threaded on the lead screw 422. The lead screw slider 423 has a cuboid structure and a protrusion at its bottom that matches the sliding groove on the inner wall of the through groove 441. The protrusion slides with the sliding groove, restricting the lead screw slider 423 to move only along the axial direction of the lead screw 422.

[0030] A connecting rod is fixed to the left side of the lead screw slider 423. The connecting rod is a stainless steel rod, and its left end is fixed to the outer wall of the needle stripping ring 424 by welding. The needle stripping ring 424 is a stainless steel ring structure, which is sleeved on the forked needle coiling rod 411, and its inner wall slides in fit with the outer wall of the forked needle coiling rod 411.

[0031] The workflow of this embodiment is as follows: Unscrew the top cap 11, place the used syringe 7 with the syringe barrel facing down, align the needle plug with the insertion hole 52, and insert it into the processing body 1. The outer wall of the syringe barrel of the syringe 7 presses against the three fixing blocks 511, compressing the spring 512. The rebound force of the spring 512 causes the fixing blocks 511 to tightly clamp the syringe barrel. Tighten the top cap 11 to limit the top of the syringe 7, completing the fixation. The control device 6 sends a signal to start the hot pressing assembly 2. The two drive cylinders 23 extend synchronously, pushing the hot pressing fixing block 21 and the heating block 22 to move in opposite directions until the positioning block 221 on the heating block 22 is completely embedded in the positioning groove 211 of the hot pressing fixing block 21. During this process, the temperature controller 24 is activated synchronously to supply power to the heating element embedded in the positioning block 221. The heating element heats up and softens the needle located between the positioning block 221 and the positioning groove 211. At the same time, under the thrust of the drive cylinder 23, the softened needle is flattened to ensure that the sharp part of the needle is completely blunted, avoiding breakage during subsequent winding. After the needle tip is softened and flattened by heat pressing, the control device 6 controls the drive cylinder 23 to retract synchronously and drives the lifting slide 3 to move upward. Since the needle winding mounting seat 44 is fixedly connected to the lifting slide 3, the needle winding assembly 4 rises synchronously with the lifting slide 3 until the flattened needle tip extends into the bifurcation gap of the bifurcation needle winding rod 411, completing the alignment before winding. After alignment, the control device 6 starts the first servo motor 41, which drives the bifurcation needle winding rod 411 to rotate. The bifurcation gap hooks the flattened needle tip. As the bifurcation needle winding rod 411 continues to rotate, the needle tip is wound into a tight metal ball. At the same time, the disinfection ultraviolet lamp 43 is turned on, emitting ultraviolet light into the rod area of ​​the bifurcation needle winding rod 411 to disinfect the needle tip during the winding process. After the winding and disinfection are completed, the lead screw slider 423 moves along the axial direction of the lead screw 422 towards the winding area of ​​the forked needle winding rod 411. The connecting rod drives the needle stripping ring 424 to slide along the axial direction of the forked needle winding rod 411, smoothly pushing away the needle bundle wound on the forked needle winding rod 411. The needle bundle falls into the needle collection box 12 below under the action of gravity.
