DETAILED DESCRIPTION

[0038] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0039] See also Figures 1 to 12 The present invention provides a technical solution: a purging and drying device for the inner cavity of an endoscope, a blow pipe 1, the blow pipe 1 is fixedly installed on the blow gun, and a connecting ring 11 is fixedly connected to the outer wall of the blow pipe 1;

[0040] The device is mounted on the blowing tube 1 of the blowing gun for blowing out gas through the connecting ring 11, so that the device can achieve blowing of the inner cavity of the endoscope when in use.

[0041] A connecting sleeve 3 is sleeved on the end of the blowing pipe 1 and is fixedly engaged with the connecting ring 11. A stop block 2 is provided inside the connecting ring 11 to prevent the connecting sleeve 3 from loosening from the connecting ring 11.

[0042] The connecting sleeve 3 is fixed by snapping with the connecting ring 11 so that the connecting sleeve 3 is installed on the blowing pipe 1, and the structure of the stop block 2 prevents the connecting sleeve 3 from being separated from the blowing pipe 1 during use.

[0043] A cleaning rod 4 is provided on the connecting sleeve 3 and is mounted on an end of the connecting sleeve 3 away from the air blowing tube 1. A brush layer 41 for cleaning the inner cavity of the endoscope is provided on the side wall of the cleaning rod 4;

[0044] The inner cavity of the endoscope is cleaned by the structure of the cleaning rod 4. The brush layer 41 on the surface of the cleaning rod 4 cleans and disinfects impurities in the inner cavity of the endoscope during the rotation of the cleaning rod 4 in the inner cavity of the endoscope.

[0045] An inner column 5, wherein the inner column 5 is disposed within the cleaning rod 4, and a disinfectant storage bag 52 is disposed within the inner column 5. The disinfectant in the disinfectant storage bag 52 is squeezed into the inner cavity of the endoscope by squeezing the disinfectant storage bag 52, and the inner cavity of the endoscope is cleaned in conjunction with the rotation of the cleaning rod 4;

[0046] The disinfectant storage bag 52 structure in the inner column 5 stores disinfectant for disinfecting the inner cavity of the endoscope. During use, the disinfectant is squeezed out of the disinfectant storage bag 52 and flows into the inner cavity of the endoscope. In conjunction with the structure of the brush layer 41, the inner cavity of the endoscope is deeply cleaned.

[0047] A cleaning component 7 is installed on the cleaning rod 4. An airbag 73 is installed on the side of the cleaning component 7 away from the cleaning rod 4. After the airbag 73 is inflated, it slides horizontally in the inner cavity of the endoscope and cleans the disinfectant remaining on the surface of the inner cavity of the endoscope to keep the inner cavity of the endoscope dry.

[0048] The structure of the cleaning component 7 is such that when the entire device is removed from the inner cavity of the endoscope, the airbag 73 expands and comes into contact with the inner wall of the endoscope, absorbing the residual moisture on the inner wall and keeping the inner cavity of the endoscope dry.

[0049] The connecting ring 11 is fixed on the outer wall near the end of the blowing pipe 1. A card slot 12 is provided on the outer wall of the connecting ring 11. There are several card slots 12, and the card slots 12 are distributed circumferentially on the connecting ring 11. The card slot 12 is set to be L-shaped. A card block 31 is provided on the inner wall of the connecting sleeve 3. The card block 31 is engaged with the card slot 12. The card block 31 is set to be L-shaped. The number of the card blocks 31 corresponds to the number of the card slots 12, and the card blocks 31 correspond to the distribution of the card slots 12.

[0050] Insert the clamping block 31 horizontally along the clamping slot 12 so that the connecting sleeve 3 is sleeved on the connecting ring 11, rotate the connecting sleeve 3 relative to the connecting ring 11, so that the clamping block 31 rotates in the clamping slot 12, and the end of the clamping block 31 is clamped with the clamping slot 12, so that the connecting sleeve 3 is installed on the connecting ring 11.

[0051] The inflection point of the blocking block 31 is set to an arc shape, and a movable groove 13 is set on the side of the blocking slot 12. A block 2 is horizontally slidably connected in the movable groove 13, and the block 2 is set to a trapezoid. The side of the block 2 facing the opening of the blocking slot 12 is set to a hypotenuse. The hypotenuse of the block 2 abuts against the inflection point of the blocking block 31, and the right-angled side of the block 2 facing the side of the blocking slot 12 abuts against the side wall of the blocking block 31. A first spring 21 is provided between the block 2 and the inner wall of the movable groove 13, one end of the first spring 21 is fixedly connected to the inner wall of the block 2, and the other end of the first spring 21 is fixedly connected to the inner wall of the movable groove 13. Telescopic rods 22 are respectively provided on both sides of the first spring 21, and the movable end and fixed end of the telescopic rod 22 are respectively fixedly connected to the block 2 and the inner wall of the movable groove 13.

[0052] The inflection point of the block 31 is an arc, and the outer wall of the block 2 is a bevel. In the process of inserting the block 31 into the slot 12, the arc of the block 31 abuts against the bevel of the block 2, and pushes the block 2 to retract into the movable slot 13. After the block 31 is fully inserted into the slot 12, the elastic force of the first spring 21 pushes the block 2 to pop out outward and pushes the block 31 to rotate, so that the block 31 abuts against the slot 12. The first spring 21 always gives the block 2 an outward force, so that the block 2 abuts against the outer wall of the block 31, preventing the block 31 from rotating in the opposite direction during use, causing the connecting sleeve 3 to fall off. The structure of the telescopic rod 22 limits the outward sliding distance of the block 2 to prevent the block 2 from falling off from the movable slot 13.

[0053] The connecting sleeve 3 is fixedly connected to a fixing seat 32 on the side away from the blowing pipe 1, and the cleaning rod 4 is installed in the fixing seat 32. A ball block 44 is fixedly connected to the outer wall of the end of the cleaning rod 4. The ball blocks 44 are provided in a number and are evenly distributed on the side wall of the cleaning rod 4. A rotating groove is provided on the middle inner wall of the fixing seat 32. The ball block 44 is inserted into the rotating groove of the fixing seat 32, and the cleaning rod 4 is rotatably connected to the connecting sleeve 3 through the ball block 44.

[0054] The cleaning rod 4 is fixed in the fixing seat 32 by the structure of the fixing seat 32, and since the ball block 44 is rotatably connected to the rotating groove, after the cleaning rod 4 is installed on the connecting sleeve 3, the two can rotate relative to each other, but the cleaning rod 4 and the connecting sleeve 3 will not separate.

[0055] A guide plate 33 is installed in the middle of the connecting sleeve 3, and a guide groove 34 connected on both sides is provided on the guide plate 33. The guide groove 34 is inclined on the guide plate 33. The inner wall of the cleaning rod 4 facing the connecting sleeve 3 is provided with blades 43. The blades 43 are inclined and distributed circumferentially in the connecting sleeve 3. The gas blown out of the blowing pipe 1 is obliquely introduced into the cleaning rod 4 through the guide groove 34, and blows the blades 43 to rotate, thereby driving the cleaning rod 4 to rotate on the connecting sleeve 3.

[0056] The structure of the drainage groove 34 guides the gas blown out of the blowing pipe 1 so that after entering the cleaning rod 4, the airflow enters at an angle and pushes the blade 43 to rotate, thereby causing the blade 43 to rotate relative to the guide plate 33, driving the cleaning rod 4 to rotate on the connecting sleeve 3.

[0057] The inner column 5 is configured to be a truncated cone, and the inner column 5 is diffused toward one end of the connecting sleeve 3. The gas blown out of the air tube 1 diffuses outward through the end of the inner column 5, and a plurality of openings 42 are provided on the side wall of the cleaning rod 4. The number of the openings 42 is staggered with the number of the brush layer 41, and the gas blown into the air tube 1 enters the inner cavity of the endoscope from the openings 42.

[0058] The airflow blown into the cleaning rod 4 in the air blowing tube 1 diffuses outward after contacting the end of the inner column 5, so that the airflow can blow air into the inner cavity of the endoscope along the opening 42. After the brush layer 41 scrapes off the stains remaining in the inner cavity of the endoscope, the airflow in the opening 42 is cooperated to blow away the impurities. Together, the stubborn impurities in the inner cavity of the endoscope are cleaned. At the same time, the drying rate of the inner cavity of the endoscope is accelerated by blowing.

[0059] A plurality of fixing columns 57 are fixedly connected to the side wall of the inner column 5, and the inner column 5 is fixed to the middle part of the cleaning rod 4 by the plurality of fixing columns 57. A mounting column 51 is installed in the inner column 5, and a disinfectant storage bag 52 is installed in the mounting column 51. A first push plate 8 is slidably connected to the inner side of the inner column 5, and the first push plate 8 is squeezed and connected to the disinfectant storage bag 52. A connecting rod 81 is fixedly connected to the side of the first push plate 8 away from the disinfectant storage bag 52, and the connecting rod 81 passes through the inner column 5 and the connecting sleeve 3, and the connecting rod 81 extends into the air blowing tube 1. The end of the connecting rod 81 is fixedly connected to a second push plate 82, and the second push plate 82 is pushed by the airflow in the air blowing tube 1.

[0060] The inner column 5 is fixed in the cleaning rod 4 by the fixing column 57, and the disinfectant storage bag 52 is installed in the inner column 5 by the mounting column 51. When the air blowing tube 1 is blowing, the airflow in the air blowing tube 1 drives the second push plate 82 to slide horizontally toward the cleaning rod 4. Under the connecting action of the connecting rod 81, the first push plate 8 is pushed to move in the same direction as the second push plate 82, and the first push plate 8 squeezes the disinfectant storage bag 52, so that the disinfectant in the disinfectant storage bag 52 is squeezed into the inner cavity of the endoscope, so as to disinfect during the cleaning of the inner cavity of the endoscope.

[0061] A plurality of outlet pipes 53 are installed on the side wall of the inner column 5. The inner side of the outlet pipe 53 extends into the disinfectant storage bag 52. The outlet pipe 53 is sealed with the disinfectant storage bag 52. The outer side of the outlet pipe 53 extends to the opening 42 of the cleaning rod 4. A fixing ring 55 is fixedly connected to the inner wall of the outer side of the outlet pipe 53. A discharge pipe 6 is slidably connected in the fixing ring 55. The discharge pipe 6 is a cavity structure with an opening toward one side of the disinfectant storage bag 52. The inner outer wall of the discharge pipe 6 is fixed. A connecting plate 62 is connected, and a sealing slide is formed between the connecting plate 62 and the inner wall of the outlet pipe 53 and between the discharge pipe 6 and the fixed ring 55. A plurality of discharge grooves 61 are provided on the outer wall of the discharge pipe 6. A sealing gasket 56 is provided on the inner wall portion of the outlet pipe 53 located outside the fixed ring 55. The sealing gasket 56 is sealed and connected to the outer side of the discharge pipe 6. A second spring 63 is provided on the outer side of the connecting plate 62, and the two ends of the second spring 63 are fixedly connected to the connecting plate 62 and the inner wall of the fixed ring 55 respectively.

[0062] During the process of the disinfectant being squeezed out, the disinfectant moves outward along the outlet tube 53, pushing the discharge tube 6 to slide outward until the discharge groove 61 on the discharge tube 6 moves to the outside of the sealing gasket 56, so that the disinfectant enters the inner cavity of the endoscope. In the initial state, when the internal disinfectant fluid pressure is not strong enough to push the discharge tube 6 outward, the connecting plate 62 slides toward the inside of the fixing ring 55 under the elastic force of the second spring 63, so that the discharge groove 61 remains in the sealing gasket 56, preventing the discharge groove 61 from discharging the disinfectant when not in use.

[0063] A cleaning assembly 7 is provided at the end of the cleaning rod 4. A connecting column 71 is fixedly connected to the side of the cleaning assembly 7 facing the cleaning rod 4. The connecting column 71 is threadedly connected to the inner wall of the cleaning rod 4. A rotating disk 72 is rotatably installed in the connecting column 71.

[0064] The rotating disk 72 is provided with a plurality of through holes, and the inner wall of the inner column 5 is provided with a plurality of air guide tubes 54. The air guide tubes 54 extend into the rotating disk 72 and penetrate into the through holes of the rotating disk 72. The air guide tubes 54 introduce gas into the airbag 73 to inflate the airbag 73.

[0065] During the process of blowing air into the cleaning rod 4 through the air blowing tube 1, part of the gas enters the cleaning assembly 7 along the air guide tube 54, causing the air pressure inside the airbag 73 to increase, thereby causing the airbag 73 to expand, and the airbag 73 to press against the inner wall of the endoscope. The airbag 73 in this state is pulled outward to remove the residual moisture and impurities in the inner cavity of the endoscope, ensuring that the endoscope is efficiently cleaned, disinfected and dried.
