Description

Technical Field

[0001] This invention relates to a water-air synergistic instrument disinfection device, specifically a device for disinfecting precision surgical instruments, endoscopes and their accessories, dental instruments, etc., belonging to the field of instrument disinfection technology. In particular, it relates to a device that uses an aeration disc to generate bubbles in the disinfectant solution during the disinfection process. These bubbles, through continuous up-and-down movement and small-amplitude oscillation within the cleaning chamber, generate turbulence. The combination of bubbles and water flow creates turbulence, which can more effectively flush instrument surfaces and hard-to-reach areas, accelerate the mixing of cleaning agent and water, and remove bacteria and residues. 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. Summary of the Invention

[0004] To improve the above situation, the present invention provides a water-air synergistic instrument disinfection device that generates bubbles in the disinfectant solution during the disinfection process through an aeration disc. The bubbles are continuously moved up and down and oscillated slightly in the cleaning solution through the cleaning chamber to generate turbulence. The bubbles combine with the water flow to form turbulence, which can more effectively flush the instrument surface and dead corners, accelerate the mixing of cleaning agent and water, and remove bacteria and residues.

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 movably placed 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 pipe (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.
