Detailed implementation manners

[0027] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0028] As Figures 1-7 shown, a clinical medical device cleaning and disinfection device includes a device housing 1. A sealing cover 2 is rotatably provided at the upper end of the device housing 1. An ultraviolet disinfection lamp 3 is fixed at the lower end of the sealing cover 2. The ultraviolet disinfection lamp 3 is a prior art. Since the ultraviolet disinfection lamp 3 can cause harm to the human body, when the sealing cover 2 is in the closed state and the cleaning device 8 starts to work, the ultraviolet disinfection lamp 3 will be turned on. When the sealing cover 2 is in the open state, the ultraviolet disinfection lamp 3 is turned off. A storage box 4 for storing medical devices is further provided in the inner cavity of the device housing 1. A cleaning device 8 for cleaning medical devices is also provided on the bottom surface of the inner cavity of the device housing 1.

[0029] As Figures 1-5As shown in the figure, the cleaning device 8 includes a cleaning bucket 81. At the bottom surface of the inner cavity of the cleaning bucket 81, a driving motor 82 is fixed. The driving motor 82 adopts a waterproof design to prevent damage to the driving motor 82 when the device cleans medical devices, ensuring its stable operation in the cleaning liquid. At the output end of the driving motor 82, a rotating disk 83 is fixed. The fixed end of the driving motor 82 is fixed to the bottom surface of the inner cavity of the cleaning bucket 81. When the driving motor 82 works, it can drive the rotating disk 83 to rotate. In the middle of the upper end of the rotating disk 83, an adjusting component 84 is arranged. At the upper end of the rotating disk 83, a plurality of mounting grooves 85 are fixed in an annular array. At the bottom surface of the inner cavity of the mounting groove 85, a plurality of first return springs 86 are fixed. At the upper end of the first return spring 86, a baffle 87 that slides in the mounting groove 85 is fixed. Further, for the convenience of placing medical devices, a plurality of baskets 88 and hooks 89 are also fixed on the inner wall of the cleaning bucket 81 for placing medical devices with larger volumes or irregular shapes (such as forceps, scissors, etc.). On the side wall of the inner cavity of the cleaning bucket 81, a drain pipe is also arranged. A filter screen is also arranged at the connection between the drain pipe and the cleaning bucket 81 (both the drain pipe and the filter screen are not shown in the figure). The drain pipe and the filter screen are both prior arts and can prevent the drain pipe from being blocked by garbage.

[0030] As Figures 2-7 shown in the figure, the adjusting component 84 includes a mounting box body 841 fixed to the upper end of the rotating disk 83. A screw rod 842 is rotatably arranged at the upper end of the mounting box body 841. A nut 843 is sleeved on the outer surface of the screw rod 842. On the outer surface of the nut 843, a plurality of groups of mounting brackets 844 are fixed in an annular array. The number of each group of mounting brackets 844 is two. At the mutually approaching ends of the two mounting brackets 844 in the same group, guiding grooves 845 are respectively opened. A guiding rod 846 is jointly arranged inside the two guiding grooves 845. Among them, the two mounting brackets 844 in the same group are used to support the guiding rod 846. And due to the arrangement of the guiding grooves 845, the guiding rod 846 can both slide and rotate in the guiding grooves 845.

[0031] In addition, one end of the guiding rod 846 away from the mounting bracket 844 rotates inside the mounting groove 85 on the side far from the center of gravity. Through the mutual cooperation between the guiding rod 846, the guiding rod 846 and the mounting groove 85, the nut 843 can be limited so that it cannot rotate. At the same time, through the mutual cooperation between the screw rod 842 and the nut 843, when the screw rod 842 rotates, the nut 843 can move upward or downward. Through the mutual connection between the guiding rod 846 and the mounting groove 85 and the guiding groove 845, when the nut 843 moves upward, the side of the guiding rod 846 away from the mounting groove 85 will move away from the side of the nut 843, and at the same time, the side of the guiding rod 846 close to the mounting groove 85 will rotate.

[0032] As Figure 3As shown, a gear 847 is rotatably installed inside the installation box body 841. A rack 848 that meshes with the gear 847 is also slidably arranged on the bottom surface of the inner cavity of the installation box body 841. Counterweight blocks are fixed to one ends of the two racks 848 away from the gear 847. Due to the design of the meshing between the rack 848 and the gear 847, when the two racks 848 move in opposite directions, the gear 847 will rotate. A second return spring 849 connected to the side wall of the installation box body 841 is also fixed to one end of the rack 848 away from the counterweight block. When the driving motor 82 rotates, it will drive the rotating disk 83 to rotate. Due to the design of the counterweight block and the second return spring 849, under the action of centrifugal force, the faster the rotating disk 83 rotates, the farther the rack 848 moves (when the rotating disk 83 rotates, the counterweight block will drive the rack 848 to move outward, and the faster the rotation speed, the farther the rack 848 moves outward). At the same time, due to the meshing between the gear 847 and the rack 848, the larger the rotation angle of the gear 847 is.

[0033] In addition, the gear 847 is fixedly connected to the screw rod 842. When the gear 847 rotates, it can drive the screw rod 842 to rotate. Since the screw rod 842 is threadedly connected to the nut 843, and due to the design of the cooperation between the guide rod 846 and the guide rod 846 and the installation groove 85, when the counterweight block moves outward, the nut 843 will move upward, and multiple guide rods 846 will tilt upward. Since a first return spring 86 and a baffle 87 are also arranged inside the installation groove 85, when the guide rod 846 tilts upward, under the action of the first return spring 86, multiple baffles 87 will move upward to form a stepped shape. Further, to increase the integral effect between the guide rod 846 and the baffle 87, a groove adapted to the baffle 87 (not shown in the figure) is also opened inside the guide rod 846. When the baffle 87 moves upward, a part of it is located inside the groove of the guide rod 846. The guide rod 846 and multiple gears 847 together form a stirring blade. When the rotating disk 83 rotates, it can stir the cleaning liquid inside the cleaning bucket 81 to rotate, so as to achieve the purpose of cleaning medical devices.

[0034] When the device is in use, the inclination angle of the guide rod 846 will affect the water flow pattern inside the cleaning bucket 81:

[0035] ① When the angle is small (such as 20° - 30°), the convex rib has a low inclination degree. When rotating, it mainly generates a horizontal water flow, forming a gentle "stirring type" tumbling, avoiding the convex rib directly hitting the surface of the instrument, preventing coating peeling and mirror scratching. At the same time, the internal water flow of the lumen type instrument is less disturbed, reducing the retention of fibers or debris. It is mainly applicable to precision instruments (endoscopes, glassware, microsurgical instruments) and vulnerable instruments (silicone catheters, plastic connectors, coated instruments);

[0036] ②When the angle is medium (such as 40° - 50°), the convex ribs form a golden angle with the impeller plane, pushing the water flow to rise obliquely and then fall back, generating a spiral eddy current (similar to "waterfall flow"), which can efficiently remove dirt and shorten the cleaning time. It is mainly applicable to conventional instruments (surgical blades, hemostatic forceps, dressing bowls) and compound contaminated instruments (instruments with mixed blood stains, tissue fragments, and grease after surgery).

[0037] ③When the angle is large (such as 60° - 75°), the convex ribs are almost perpendicular. When rotating, a strong vertical impact force is generated. The water flow rebounds after hitting the barrel wall at high speed, forming a "scouring" washing method, greatly improving the removal rate of dried blood stains and grease, directly skipping the pre-soaking step, and improving work efficiency. It is mainly applicable to severely contaminated instruments (orthopedic surgical instruments, infectious instruments) and wear-resistant instruments (bone chisels, intramedullary nails, sterilization cans).

[0038] When the device is in use, it only needs to adjust the rotation speed of the rotating disk 83 according to different medical devices, without complex working steps, which facilitates the operation of the device.

[0039] Furthermore, to make the device more stable during use, both the gear 847 and the rack 848 are made of plastic material, which can reduce the interference of the device on the counterweight during use. When the rotating disk 83 rotates, the rack 848 can move outward more smoothly, improving the sensitivity of the device during use.

[0040] The specific implementation method of this embodiment is as follows: First, surgical forceps, tweezers, etc. that need to be cleaned and disinfected are suspended or placed on the hook 89 through the basket 88 to ensure stable center of gravity. Then, the appropriate rotation speed is adjusted according to the classification of the instruments. When the rotating disk 83 rotates, under the action of centrifugal force, the two counterweights move outward to the outer circle, and then the screw 842 rotates through the cooperation between the gear 847 and the rack 848. When the screw 842 rotates, the installation bracket 844 moves upward through the threaded connection with the nut 843 to adjust the inclination angle of the guide rod 846, so that the device can automatically adjust the water flow pattern according to the rotation speed during use, thus being applicable to different medical devices.

[0041] It should be noted that the specific installation methods, circuit connection methods, and control methods of the ultraviolet disinfection lamp 3, the drive motor 82, the gear 847, the rack 848, etc. in the present invention are all conventional designs, and the present invention will not elaborate in detail.
