Description

Technical Field

[0001] This invention relates to a multi-stage transmission mixed-flow rinsing structure and a water-air synergistic instrument disinfection device. It is a multi-stage transmission mixed-flow rinsing structure installed on a water-air synergistic instrument disinfection device to fully agitate the water flow around the cleaning chamber. It belongs to the field of instrument disinfection technology. In particular, it relates to a multi-stage transmission mixed-flow rinsing structure that uses a single motor and a continuous transmission mechanism to control multiple mixing plates to rotate on a support ring, agitating the water flow to enhance the rinsing effect on the instruments. Background Technology

[0002] Surgical forceps, tweezers, hysteroscopes, bronchoscopes, laparoscopes and their accessories, as well as hemostatic clips, anastomosing devices, and other instruments are prone to contact with patients' blood, body fluids, and tissues during use. They require thorough cleaning and disinfection after use to prevent cross-infection. Immersion disinfection can effectively kill or remove pathogenic microorganisms while maintaining the cleanliness of the instruments and preventing corrosion and damage. Currently, there are two common disinfection methods: vibration immersion disinfection, which involves adding cleaning solution to a washing tank and using mechanical vibration to promote liquid flow, accelerating the removal and dissolution of contaminants on the instrument surface; and fixed-nozzle rinsing disinfection, which uses high-pressure water jets to rinse medical instruments, thereby achieving the purpose of cleaning and disinfection. However, for delicate or complex instruments containing small pipes, curved pipes, or crevices, vibration cleaning has limited rinsing effect due to the small amplitude of liquid vibration, and cannot completely remove bacteria and residues from crevices or pipes. Fixed rinsing, on the other hand, is difficult to clean all surfaces, resulting in incomplete cleaning.

[0003] Publication No. CN209122953U discloses a medical gynecological and obstetric surgical instrument sterilization device, including a base. The device is characterized by: a motor, an L-shaped support column, and a fixing block fixedly connected to the base; a first bevel gear fixedly connected to one end of a connecting shaft, which passes through the fixing block and is fixedly connected to a second bevel gear; the first bevel gear meshes with a fourth bevel gear; the central shaft at the lower end of the fourth bevel gear is hinged to the base; the central shaft at the upper end of the fourth bevel gear is fixedly connected to a sterilization tank; the sterilization tank is equipped with a valve; an isolation net is fixedly connected inside the sterilization tank; the second bevel gear meshes with a third bevel gear; the output shaft of the motor is fixedly connected to the third bevel gear; an L-shaped rod is fixedly connected to the central shaft at the upper end of the third bevel gear; a pin at the other end of the L-shaped rod is disposed in a sliding groove; the sliding groove is disposed on a swing rod; and a connecting shaft is fixedly connected to one end of the swing rod. Publication No. CN216319028U discloses a sterilization device for surgical nursing instruments, including a sterilization tank and a support frame. The support frame is fixed to the outer side wall of the sterilization tank. A connected sterilization chamber is fixed to the bottom side wall of the sterilization tank, and an interconnected water outlet pipe is fixed to the inner side wall of the bottom of the sterilization chamber. An internally connected water inlet pipe is fixed to one side wall of the sterilization tank. Publication No. CN212395438U discloses a sterilization device for cerebrovascular treatment instruments, including a working plate. The working plate is characterized by: the lower ends of the working plate being fixedly connected to the upper ends of a corresponding set of sterilization tanks; the upper ends of the working plate being fixedly connected to the lower ends of symmetrical rectangular blocks; the opposite sides of the two sets of rectangular blocks being fixedly connected to the ends of corresponding guide rods; and the middle portions of the opposite sides of the two guide rods being fixedly connected to the corresponding ends of the rectangular plates. The aforementioned devices use vibration soaking or fixed rinsing to disinfect and clean instruments. However, for delicate or complex instruments containing small pipes, curved pipes, or gaps, vibration cleaning has limited rinsing effect due to the small amplitude vibration of the liquid, and cannot completely remove bacteria and residues in the gaps or pipes. Fixed rinsing is also difficult to rinse all surfaces, resulting in insufficient cleaning.

[0004] To address the aforementioned issues, the applicant filed a separate Chinese invention patent application entitled "A Water-Air Synergistic Instrument Disinfection Device." This device uses an aeration disc to generate bubbles in the disinfectant solution during the disinfection process. These bubbles, along with the continuous up-and-down movement and slight oscillation of the cleaning chamber within the cleaning solution, create turbulence. The combination of bubbles and water flow forms this turbulence, which effectively washes away instrument surfaces and hard-to-reach areas, accelerates the mixing of cleaning agent and water, and removes bacteria and residues. However, the water flow in the cleaning tank of this water-air synergistic instrument disinfection device is relatively weak. A telescopic rod is needed to continuously move the cleaning chamber up and down to turbulent the water flow, ensuring effective washing of the instruments within the cleaning chamber. If there are many or heavy instruments to be cleaned, the telescopic rod bears a heavy burden, and continuous operation can easily lead to its failure, resulting in low reliability of the device.

Detailed Implementation

[0011] The multi-stage transmission mixed-flow flushing structure and water-air synergistic instrument disinfection device of the present invention are implemented as follows: The multi-stage transmission mixed-flow flushing structure of the present invention consists of a support ring (13), a mixing plate (14), a second transmission rod (15), a first transmission rod (16), a motor (17), a rotating shaft (18), a driving gear (19), a driven gear (20), a rotating ring (21), a fixed column (22), a connecting sleeve (23), and a motor housing (24). The motor housing (24) is placed on the inner wall of the cleaning tank (4) of the water-air synergistic disinfection device. Preferably, the motor housing (24) is made of stainless steel and the inner wall is coated with an epoxy resin coating. The motor (17) is placed on the inner wall of the motor housing (24), the rotating shaft (18) is placed on the motor (17), the motor (17) can drive the rotating shaft (18) to rotate, the drive gear (19) is placed on the rotating shaft (18), and a section of the arc length of the support ring (13) is placed inside the motor housing (24). Preferably, a sealing sleeve is provided between the support ring (13) and the motor housing (24). Preferably, the cross-section of the support ring (13) is rectangular, and the long side of the rectangle is perpendicular to the radial direction of the support ring (13). Preferably, a connecting rod is provided on the side of the support ring (13) near the motor housing (24). One end of the connecting rod is fixedly connected to the side of the support ring (13), and the other end is connected to the inner wall of the cleaning tank by a thread. Preferably, the support ring (13) is located outside the cleaning chamber (12). Multiple connecting sleeves (23) are equidistantly fitted onto the support ring (13), and multiple rotating rings (21) are respectively fitted onto the multiple connecting sleeves (23) in a corresponding manner. Preferably, the connecting sleeve (23) has outwardly extending protruding edges at both ends. Preferably, a sealed bearing is provided between the rotating ring (21) and the connecting sleeve (23). Preferably, one of the rotating rings (21) is partially housed within the motor housing (24). Preferably, a sealed bearing is provided between one of the rotating rings (21) and the motor housing (24). The driven gear (20) is fitted onto the rotating ring (21) located inside the motor housing (24). The driven gear (20) meshes with the driving gear (19). One end of the second transmission rod (15) is rotatably mounted on the rotating ring (21) via the fixed column (22), and the other end of the second transmission rod (15) is rotatably mounted on the mixing plate (14) via the fixed column (22). One end of the first transmission rod (16) is rotatably mounted on the rotating ring (21) via the fixed column (22), and the other end of the first transmission rod (16) is rotatably mounted on the mixing plate (14) via the fixed column (22). Preferably, the first transmission rod (16) and the second transmission rod (15) are a set rotatably positioned at both ends of the mixing plate (14), that is, the first transmission rod (16) and the second transmission rod (15) on adjacent rotating rings (21) drive the commonly connected mixing plate (14) to rotate around the support ring (13). Preferably, a limiting head is provided at the upper end of the fixing column (22), and the cross-section of the limiting head is larger than the cross-section of the fixing column (22). Preferably, the mixing plate (14) adopts a multi-layer blade structure, with each layer of blades forming a certain angle of inclination, and the edge of the mixing plate (14) has a continuously bent arc-shaped edge. Preferably, the surface of the mixing plate (14) has a plurality of regularly arranged small holes. In use, the motor (17) first drives the rotating shaft (18) to rotate, thereby driving the driving gear (19) and the driven gear (20) to rotate. The driven gear (20) drives one of the rotating rings (21) to rotate. One of the rotating rings (21) drives the first transmission rod (16), the mixing plate (14), and the second transmission rod (15) to rotate in sequence. The second transmission rod (15) then drives the rotating ring (21) on it to rotate, so that a single motor (17) can drive all the mixing plates (14) to rotate around the support ring (13). The two ends of the first transmission rod (16) and the second transmission rod (15) are respectively rotated and placed on the rotating ring (21) and the mixing plate (14) through the fixed column (22). When the rotating ring (21) rotates around the support ring (13), the first transmission rod (16) and the second transmission rod (15) can automatically adjust the rotation angle to compensate for the change in lateral distance during the rotation process, so as to ensure that the mixing plate (14) stably stirs the water around the cleaning chamber (12), improves the flushing force of the water flow on the medical instruments inside the cleaning chamber (12), and improves the cleaning effect. The design of placing a sealed bearing between one of the rotating rings (21) and the motor housing (24) ensures that water cannot enter the motor housing (24) while the rotating ring (21) rotates, reduces the friction force on the rotating ring (21) during rotation, and improves the rotation efficiency of the rotating ring (21). The support ring (13) has a rectangular cross-section, and the long side of the rectangle is perpendicular to the radial direction of the support ring (13), which enables the support ring (13) to have higher stability when subjected to radial force. The design of the connecting sleeve (23) with outwardly extending protruding edges at both ends can effectively limit the position of the rotating ring, prevent it from detaching from the connecting sleeve (23) during rotation, and improve the stability of turbulent scouring. A limiting head is provided at one end of the fixed column (22). The cross-section of the limiting head is slightly larger than the cross-section of the fixed column (22), which enables the first transmission rod (16) and the first transmission rod (16) to rotate stably on the mixing plate (14) and the rotating ring (21). The mixing plate (14) adopts a multi-layer blade structure, with each layer of blades forming a certain angle of inclination. The design of the continuously bent arc edge of the mixing plate (14) can guide the water flow to form a multi-layer vortex motion. The wave-shaped edge further disturbs the water flow, enhances the kinetic energy and impact force of the water flow, and better washes and cleans the equipment. The design of multiple regularly arranged small holes on the surface of the mixing plate (14) can prevent dirt and impurities from adhering to the surface of the mixing plate (14), while increasing the turbulence of the water flow and enhancing the flushing effect on medical devices. The goal is to achieve the effect of controlling multiple mixing plates to rotate on the support ring using a single motor and continuous transmission mechanism, thereby agitating the water flow and enhancing the scouring effect on the equipment.

[0012] It should be noted that the multi-stage transmission mixed-flow flushing structure needs to be installed in one of the following water-air synergistic disinfection devices; The aforementioned water-air synergistic disinfection device comprises a spraying structure and a cleaning and filtration structure. The spraying structure consists of a fixed frame (7), a second telescopic rod (8), a water tank (9), and a spray head (10). The fixed frame (7) is placed on the water tank (9), and the second telescopic rod (8) is placed on the fixed frame (7). Preferably, the second telescopic rod (8) has an internal water inlet channel, with an inlet and an outlet at each end, and a sealing ring is provided at the telescopic part of the second telescopic rod (8). The water tank (9) is connected to one end of the second telescopic rod (8) which has a water inlet. The water tank (9) has a built-in water pump. Preferably, the water pump is connected to the inlet of the second telescopic rod (8) via a water pipe. The spray head (10) is connected to the other end of the second telescopic rod (8) which has a water outlet. Preferably, the spray head (10) is a cone with its tip pointing downwards, and multiple nozzles at different angles are evenly distributed on the downward-facing conical surface, with the nozzles at the tip of the spray head (10) pointing vertically downwards. The cleaning and filtration structure consists of a crossbeam (1), a telescopic rope (2), first telescopic rods (3), a cleaning tank (4), an air pump (5), an air guide pipe (6), an aeration disc (11), and a cleaning chamber (12). One end of each of the two first telescopic rods (3) is symmetrically placed on the cleaning tank (4), and both ends of the crossbeam (1) are connected to the other ends of the two first telescopic rods (3). Preferably, the first telescopic rod (3) is made of carbon fiber composite material, which is lightweight and has high strength. Preferably, the connection between the first telescopic rod (3) and the crossbeam (1) is a ball joint, enabling multi-angle rotation. The cleaning chamber (12) is movable inside the cleaning box (4). Preferably, the cleaning chamber (12) is made of silicone material, with steel wire reinforcing ribs wrapped around its outer layer. Preferably, the bottom and sidewalls of the cleaning chamber (12) are designed with a mesh pattern, and the mesh diameter is 2-5 mm. One end of each of the two telescopic ropes (2) is symmetrically placed on the cleaning chamber (12), and the other end of each of the two telescopic ropes (2) is placed on the crossbeam (1). Preferably, the telescopic rope (2) is made of a blend of elastic polyester fiber and nylon, and the surface of the telescopic rope (2) is coated with a waterproof and corrosion-resistant coating. Preferably, the telescopic rope (2) and the cleaning chamber (12) are detachably connected. Preferably, the telescopic rope (2) and the crossbeam (1) are detachably connected. The aeration disc (11) is placed on the inner wall of the bottom of the cleaning tank (4), the air pump (5) is placed outside the cleaning tank (4), and the air guide pipe (6) passes through the side wall of the cleaning tank (4) and is connected to the air pump (5). One end of the air guide pipe (6) is connected to the aeration disc (11). Preferably, a sealing sleeve is provided between the air guide tube (6) and the side wall of the cleaning box (4); In use, first place the instrument to be cleaned inside the cleaning chamber (12), extend the second telescopic rod (8), and place the spray head (10) directly above the cleaning chamber (12). The water pump delivers water from the water tank (9) through the second telescopic rod (8) to the spray head (10) to perform initial spray cleaning on the instrument. Then, pour the cleaning agent into the cleaning chamber (12), and the spray head (10) continuously injects water into the cleaning tank (10). Start the air pump, and the aeration disc (11) at the bottom of the cleaning tank (10) injects air into the water to increase the fluidity of the water and accelerate the contact and mixing of cleaning agent molecules and water molecules. During the water injection process, the cleaning chamber (12) swings slightly with the water flow to disturb the water flow and accelerate the mixing of water and cleaning agent. After the water is injected, the device is soaked for a period of time. The first telescopic rod (3) is controlled to continuously extend and retract, causing the cleaning chamber (12) and the instruments inside to move up and down and swing slightly in the cleaning solution. The cleaning solution forms a turbulent flow to flush the various surfaces and corners of the instruments. With the help of the air bubbles in the aeration plate, water and air work together to flush away bacteria and residues on the instruments. Then, the first telescopic rod is controlled to lift the cleaning chamber (12) through the crossbeam (1) and telescopic rope (2). The wastewater after cleaning flows out from the mesh on the surface of the cleaning chamber. Then, the spray head (10) performs a second flush on the medical instruments in the cleaning chamber to avoid the cleaning agent remaining on the medical instruments. The water remaining on the surface of the medical instruments will flow out from the mesh of the cleaning chamber (12). The second telescopic rod (8) has an internal water inlet channel, with an inlet and an outlet at each end, providing telescopic functionality while ensuring smooth water flow. The telescopic section of the second telescopic rod (8) is equipped with a sealing ring to prevent leakage at the connection point. The spray head (10) is a cone with the tip pointing downwards. The design of having multiple nozzles at different angles evenly distributed on the downward-facing conical surface ensures that clean water is sprayed in a wide and uniform manner, improving the uniformity of cleaning. The first telescopic rod (3) is made of carbon fiber composite material, which is sufficient to bear the load of the crossbeam (1), the cleaning chamber (12) and the medical equipment, and maintains stability and corrosion resistance during long-term use. The connection between the first telescopic rod (3) and the crossbeam (1) adopts a ball joint to realize the design of multi-angle rotation, which can adapt to the tilt or displacement that the cleaning chamber (12) may produce during the cleaning and filtration process, and ensure that the support force is always evenly distributed. The cleaning chamber (12) is made of silicone material, which can prevent the instruments from being damaged by collision with the inner wall of the cleaning chamber (12) during the cleaning process. The cleaning chamber (12) has a mesh design on its bottom and side walls, with a mesh diameter of 2-5 mm. This design provides support for the instruments while draining wastewater, enhancing ventilation and drying effects. The telescopic rope (2) is made of a blend of elastic polyester fiber and nylon, which improves its durability and tensile strength. It stabilizes the cleaning chamber (12) in water. The surface of the telescopic rope (2) is coated with a waterproof and corrosion-resistant coating, enabling it to be used in water for extended periods without aging or corrosion. The aeration disc generates bubbles in the disinfectant solution during the disinfection process. These bubbles then move up and down and oscillate slightly in the cleaning solution through the cleaning chamber, creating turbulence. The combination of bubbles and water flow forms turbulence, which can more effectively flush the surface of instruments and dead corners, accelerate the mixing of cleaning agent and water, and remove bacteria and residues.
