[0002] Tubular instruments are commonly used instruments, especially in hospitals and chemical laboratories. Test tubes and other tubular instruments are widely used. After use, tubular instruments generally need to be thoroughly disinfected and cleaned. Currently, thin brushes are generally used to clean these instruments.

[0003] Endoscopic instruments need to be cleaned after a period of use. Generally, the cleaning operation is carried out by rotating and pulling the cleaning brush. However, the cleaning brush consists of a brush handle and bristles. The diameter of the brush handle is small, making it difficult for the user to drive the vertical handle to rotate, which reduces the cleaning efficiency of the endoscope.

[0004] Therefore, we propose a medical lumen instrument cleaning brush to address the problems mentioned above. Utility Model Content

[0024] Example 1

[0025] Please see Figure 1-5 A medical tubular instrument cleaning brush includes a connecting rod 1, a circular tube 2 rotatably connected to the outer periphery of the connecting rod 1 near its top end (a bearing is fixedly installed at the center of the bottom of the inner cavity of the circular tube 2, and the bottom end of the connecting tube 1 passes through the inner cavity of the bearing), a driving assembly 7 is provided in the inner cavity of the circular tube 2, a stop block 3 is fixedly installed at the bottom end of the connecting rod 1, a connecting tube 4 is fixedly installed at the bottom of the stop block 3, a brush tube 5 is slidably connected to the outer periphery of the connecting tube 4, and a plurality of bristles 6 (the bristles 6 are nylon bristles) are fixedly installed on the outer periphery of the brush tube 5, and a disassembly assembly 8 is provided between the connecting tube 4 and the brush tube 5.

[0026] The drive assembly 7 includes a movable plate 72 located near the top of the inner cavity of the circular tube 2 and a T-shaped rod 71 fixedly installed on the top of the movable plate 72. A drive rod 73 is fixedly installed at the bottom center of the movable plate 72, and a drive tube 74 is fixedly installed at the top of the connecting rod 1. The drive rod 73 is movably inserted into the inner cavity of the drive tube 74. (The principle is similar to the children's toy "hand-push flying saucer". The drive rod 73 is similar to a spiral. When it moves downward, it can make the drive tube 74 rotate.)

[0027] A reset telescopic rod 721 is fixedly installed at the bottom of the movable plate 72 near both sides. The bottom end of the reset telescopic rod 721 is fixedly connected to the bottom of the inner cavity of the round tube 2. A reset spring 722 is movably sleeved on the outer periphery of the reset telescopic rod 721. The top and bottom ends of the reset spring 722 are fixedly connected to the movable plate 72 and the bottom of the inner cavity of the round tube 2, respectively.

[0028] Specifically, by setting the reset telescopic rod 721 and the reset spring 722, the movable plate 72 can be reset to its initial state when the T-shaped rod 71 is not subjected to external pressure.

[0029] Several rubber pads 21 are fixedly installed on the outer periphery of the circular tube 2. The rubber pads 21 are arranged in a circular array with the top of the circular tube 2 as the center.

[0030] Specifically, several rubber pads 21 are installed to prevent the user from slipping off when holding the round tube 2.

[0031] Several bristles 6 are distributed at equal intervals from top to bottom on the outer periphery of the brush tube 5.

[0032] Specifically, by equidistantly arranging bristles 6 on the outer periphery of the brush tube 5, the cleaning effect on the endoscope can be improved.

[0033] Several positioning blocks 41 are fixedly installed on the outer periphery of the connecting pipe 4, and a positioning groove 51 is opened on the top of the brush pipe 5, and both the positioning blocks 41 and the brush pipe 5 move through the inner cavity of the positioning groove 51.

[0034] Specifically, by setting the positioning block 41 and the positioning groove 51, the brush tube 5 can be rotated when the connecting tube 4 rotates.

[0035] Example 2

[0036] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 3 and Figure 4 The disassembly assembly 8 includes a circular groove 87 located near the bottom of the inner cavity of the connecting pipe 4 and a threaded pipe 82 that moves through the bottom of the inner cavity of the circular groove 87. (A bearing is fixedly installed at the bottom of the inner cavity of the circular groove 87, and the threaded pipe 82 passes through the inner cavity of the bearing.) A hexagonal nut 81 is attached to the bottom end of the threaded pipe 82. A threaded rod 83 is threadedly connected to the inner cavity of the threaded pipe 82. A movable block 84 is fixedly installed at the top end of the threaded rod 83. A hinge rod 85 is hinged to the top of each movable block 84. A T-shaped block 86 is hinged to the end of each hinge rod 85. The T-shaped blocks 86 move through the inner cavity of the circular groove 87.

[0037] Specifically, when the bristles 6 need to be replaced after prolonged use, with the cooperation of the disassembly component 8, when the movable block 84 moves upward, the adjacent T-shaped block 86 can move inward under the connection of the adjacent hinge rod 85, thereby removing the obstruction of the brush tube 5, making it easy to remove the brush tube 5 as a whole, facilitating the replacement of the bristles 6, and reducing the disassembly effort of the workers.

[0038] Limiting telescopic rods 861 are fixedly installed between two adjacent T-shaped blocks 86. Fixed telescopic rods 841 are fixedly installed at the bottom of the movable block 84 near both sides, and the bottom ends of the fixed telescopic rods 841 are all connected to the bottom of the inner cavity of the circular groove 87. Drainage holes are opened at the bottom of the inner cavity of the circular groove 87.

[0039] Specifically, the limit telescopic rod 861 can limit the movement of two adjacent T-shaped blocks 86, and the fixed telescopic rod 841 can limit the movement of the movable block 84.

[0040] Working Principle: When using this invention, the brush bristles 6 are placed inside the endoscope. During cleaning, the user presses down on the T-shaped rod 71, causing the movable plate 72 fixed at the bottom of the T-shaped rod 71 to move downwards. This compresses the reset telescopic rod 721 and the reset spring 722. As the drive rod 73 moves downwards, the drive tube 74 rotates, similar to a children's toy "hand-held flying saucer." The drive rod 73 is spiral-shaped; its downward movement causes the drive tube 74 to rotate. When the T-shaped rod 71 is released, the movable plate 72 returns to its original position under the elastic force of the reset telescopic rod 721 and the reset spring 722. The rotation of the drive tube 74 causes the connecting rod 1 to rotate, thereby enabling the... The brush tube 5 on the outer periphery of the connecting tube 4 rotates, and the endoscope can be rotated and cleaned by several bristles 6 fixed to the brush tube 5. When the bristles 6 need to be replaced, the hexagonal nut 81 is rotated by an external tool. The threaded tube 82 fixed to the hexagonal nut 81 allows the threaded rod 83, which is threaded into the inner cavity of the threaded tube 82, to pull the movable block 84 downward under the limit of two adjacent fixed telescopic rods 841. The hinge rod 85 hinged to the top of the movable block 84 allows the T-shaped block 86 to move inward under the limit of two adjacent limit telescopic rods 861, thereby removing the obstruction of the brush tube 5. Then the brush tube 5 can be removed from the outer periphery of the connecting tube 4, making it easy to remove the brush tube 5 as a whole, which facilitates the replacement of the bristles 6 and reduces the disassembly strength of the staff.
