Description

Technical Field

[0001] This utility model relates to the field of medical disinfection, specifically to an endoscope cleaning steam-water conversion device. Background Technology

[0002] In the current medical field, in order to facilitate minimally invasive treatment, endoscopes are usually used to observe the patient's internal condition and perform minimally invasive operations. After the operation, the endoscope needs to be disinfected and cleaned before it can be reused. After rinsing, enzymatic hydrolysis and soaking disinfection, the endoscope needs to be cleaned with air gun and water gun to clean the disinfectant inside the endoscope. In order to facilitate cleaning the disinfectant, an endoscope cleaning air-water conversion device is usually used to connect the air gun and water gun.

[0003] Existing endoscope cleaning air-water switching devices mainly install an air-water switching component, i.e., a reversing valve, on the endoscope's liquid inlet. By adjusting the switching switch of the air-water switching component, the direction of the air gun and water gun can be controlled.

[0004] However, cleaning the endoscope requires repeated rinsing, which necessitates moving the switch multiple times, greatly affecting the cleaning efficiency. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing endoscope cleaning air-water switching devices cannot automatically change the direction of the input port when switching between air and water.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an endoscope cleaning air-water conversion device, including an endoscope and an air-water conversion assembly connected to one side of the endoscope's water inlet. The air-water conversion assembly includes a T-shaped tee pipe and a pressure rebound assembly welded to the corner of the T-shaped tee pipe. The pressure rebound assembly includes a Z-shaped fixing piece welded to the top surface of the T-shaped tee pipe's outlet, a sealing plug blocking the inner walls of the two input pipes of the T-shaped tee pipe, and a spring plate connecting the two sides of the vertical end of the Z-shaped fixing piece and the bottom surface of the sealing plug.

[0007] As an improvement, the top surface of the output port of the T-shaped tee is provided with a storage groove for easy installation of the pressure rebound assembly, and the opening end of the storage groove is welded with a corresponding sealing cap. The top surface of the Z-shaped fixing piece is welded to the inner wall of the sealing cap through an auxiliary connecting rod.

[0008] As an improvement, the outer wall end of the sealing plug is fitted with a sealing rubber gasket, and one side of the bottom surface of the sealing plug is provided with a sloping slope to facilitate the reversal of air and water.

[0009] As an improvement, the vertical ends of the Z-shaped fixing piece and the bottom surface of the sealing plug are both connected to the spring sheet by a welding machine.

[0010] As an improvement, the bottom surface of the sealing plug connected to the spring plate is a semi-circular cylinder.

[0011] As an improvement, both the water inlet pipe and the air inlet pipe of the T-shaped tee are L-shaped.

[0012] The advantages of this invention compared to the prior art are as follows: This device uses a Z-shaped fixing plate to fix the bottom surfaces of two sealing plugs located on both sides of the input end of the T-shaped tee pipe. The Z-shaped fixing plate is welded to the top surface of the output port of the T-shaped tee pipe. The vertical ends of the sealing plugs and the Z-shaped fixing plate are then welded to spring plates. Through the elasticity of the spring plates, the sealing plugs in the direction of the air or water pipe that have stopped impacting are automatically reset. This ensures that when switching between air and water, there is no need for a secondary operation of opening the conversion structure. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] As per the instruction manual Figure 1 , 2As shown, the device includes an endoscope 1 and an air-water conversion assembly 2 connected to the water inlet side of the endoscope 1. The output end of the air-water conversion assembly 2 is inserted into the liquid inlet of the endoscope 1. The air-water conversion assembly 2 includes a T-shaped three-way tube 21 and a pressure rebound assembly 22 welded to the corner of the T-shaped three-way tube 21. To facilitate immediate air drying after washing, the water gun and air gun are fixed in the water inlet and air inlet of the T-shaped three-way tube 21 using a sealing connection valve. After the T-shaped three-way tube 21 is inserted into the water inlet of the endoscope 1, the water inlet pipe and air inlet pipe of the T-shaped three-way tube 21 are both L-shaped to facilitate the use of the water gun and air gun.

[0020] To facilitate the installation of the pressure rebound assembly 22 on the top surface of the output pipe of the T-shaped tee pipe 21, a storage groove 211 is provided on the top surface of the output port of the T-shaped tee pipe 21 for easy installation of the pressure rebound assembly 22. The opening end of the storage groove 211 is provided with a corresponding sealing cap 212. After the pressure rebound assembly 22 is installed in the storage groove 211, the top surface of the Z-shaped fixing piece 221 is welded to the inner wall of the sealing cap 212 through the auxiliary connecting rod to fix the position of the pressure rebound assembly 22. This prevents the pressure rebound assembly 22 from shifting due to the impact of high-pressure gas and high-pressure water flow during use. Finally, the sealing cap 212 is welded to the outer wall of the storage groove 211 for fixation.

[0021] As per the instruction manual Figure 2 , 3 As shown in Figure 4, the pressure rebound assembly 22 includes a Z-shaped fixing piece 221 welded to the top surface of the output port of the T-shaped tee pipe 21, a sealing plug 222 blocking the inner walls of the two input pipes of the T-shaped tee pipe 21, and a spring piece 223 connecting the two sides of the vertical end of the Z-shaped fixing piece 221 and the bottom surface of the sealing plug 222. In order to facilitate the overall transfer of the Z-shaped fixing piece 221, the sealing plug 222 and the spring piece 223, and to ensure that the spring piece 223 does not fall into the output pipe of the T-shaped tee pipe 21 during connection, the two sides of the vertical end of the Z-shaped fixing piece 221 and the bottom surface of the sealing plug 222 are connected to the spring piece 223 by a welding machine.

[0022] To ensure the sealing performance of the sealing plug 222, a sealing rubber gasket 224 is fitted on the outer wall end of the sealing plug 222; to reduce the impact force when gas and water flow enter the output end of the T-shaped tee pipe 21, a sloping slope 225 is provided on one side of the bottom surface of the sealing plug 222 to facilitate the reversal of gas and water; at the same time, to ensure a shorter connection distance at the vertical end of the Z-shaped fixing piece 221 on the bottom surface of the sealing plug 222, the bottom surfaces of the sealing plug 222 connected to the spring piece 223 are all semi-circular cylinders.

[0023] In practical implementation, the output pipe of the T-shaped three-way tube 21 is inserted into the inlet of the endoscope 1. Then, the water gun is turned on. Under the impact of the high-pressure water flow, the sealing plug 222 at this end is squeezed against the spring plate 223. At the same time, the inclined slope 225 is connected to the output pipe of the T-shaped three-way tube 21, so that water flows into the pipe of the endoscope 1 for rinsing. After rinsing, simply stop the water gun switch, and the sealing plug 222 will automatically reset under the action of the spring plate 223, completing the closure of the pipe at this end. Similarly, after the water gun is stopped, the air gun is turned on, which can automatically complete the air-water conversion of the output pipe, thereby drying the water droplets in the endoscope 1 and ensuring the cleanliness of the endoscope 1.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
