[0032] like Figures 1-10 As shown, an otolaryngological irrigation device includes a tank 1 for storing cleaning fluid. A water pipe can be installed on the tank 1 to facilitate the injection of cleaning fluid into the tank 1. A valve is installed on the water pipe. A connecting pipe 101 is integrally formed on the top surface of the tank 1. A slider 14 is installed inside the connecting pipe 101. The slider 14 has an overall annular structure, and there is a sealed fit between the slider 14 and the inner wall of the connecting pipe 101. A guide pipe 9 is provided at the center of the slider 14. Specifically, the guide pipe 9 is generally L-shaped. The bottom end of the flow tube 9 extends into the interior of the tank 1 and is located near the bottom. The flow tube 9 passes through the slider 14, and the slider 14 and the flow tube 9 are sealed together. When the slider 14 moves downward inside the connecting tube 101, the slider 14 can squeeze the cleaning fluid in the tank 1 through the flow tube 9, thereby rinsing the patient's ear canal. As an extension, the end of the flow tube 9 away from the tank 1 can be provided with a threaded structure or a corresponding snap-fit ​​structure to facilitate the installation of different fittings, which can rinse the nasal cavity or ear canal.

[0033] An annular slide plate 7 and a pressure ring 10 are sleeved on the outside of the connecting pipe 101. The pressure ring 10 is located below the slide plate 7 and is engaged with the connecting pipe 101 through a one-way bearing, so that the pressure ring 10 can only rotate in one direction relative to the connecting pipe 101. The slide plate 7 and the pressure ring 10 are engaged through a pressing component. When the slide plate 7 rotates relative to the pressure ring 10, the pressing component can drive the slide plate 7 to move upward. The slider 14 is connected to the slide plate 7 through a support rod 8. Specifically, the support rod 8 is L-shaped. The horizontal section of the support rod 8 is fixedly connected to the slide plate 7, and the vertical section of the support rod 8 is engaged with the slider 14, so that the support rod 8 can rotate in one direction relative to the slider 14.

[0034] Furthermore, a sleeve 6 is fitted on the outside of the slide plate 7. The sleeve 6 cooperates with the slide plate 7 through a limiting component, so that the sleeve 6 can drive the slide plate 7 to rotate in a single direction. In actual use, the sleeve 6 can drive the slider 14 to rotate relative to the pressure ring 10, and then drive the slide plate 7 to move upward through the squeezing component. Through the set support rod 8, the slide plate 7 can drive the slider 14 in the connecting pipe 101 to move upward. When the slider 14 returns to its original position, it can squeeze the cleaning fluid in the tank 1 into the guide pipe 9, which is beneficial for rinsing the patient's ear canal.

[0035] A drainage component is provided in the inner cavity of the slider 14. When the slider 14 is rotated relative to the guide tube 9 by the support rod 8, the cleaning fluid in the guide tube 9 can be drawn into the slider 14 through the drainage component.

[0036] like Figures 1-10 As shown, the above-mentioned extrusion assembly includes a top rod 12 disposed on the bottom surface of the slide plate 7 and fixedly connected to the slide plate 7. The top surface of the pressure ring 10 is fixedly provided with a boss 11 that cooperates with the top rod 12, and the top of the boss 11 is set as an inclined extrusion surface 1101. In specific use, multiple sets of the top rod 12 and the boss 11 can be provided. When the slide plate 7 rotates relative to the pressure ring 10, causing the top rod 12 to approach the boss 11, the inclined extrusion surface 1101 can push the top rod 12 upward, thereby driving the slide plate 7 to move upward relative to the connecting pipe 101. When the top rod 12 and the boss 11 are misaligned, the slide plate 7 can move downward and reset.

[0037] The limiting component includes a limiting block 16 disposed on the inner wall of the sleeve 6 and elastically connected to the sleeve 6, and a plurality of limiting grooves 701 that cooperate with the limiting block 16 are evenly opened on the outer wall of the slide plate 7. One end of the limiting block 16 located inside the limiting groove 701 is provided with a first inclined surface 1601. When one end of the limiting block 16 is inserted into the limiting groove 701, the first inclined surface 1601 will not be completely inserted into the limiting groove 701. Through this structure, the sleeve 6 can only drive the slide plate 7 to rotate in a single direction.

[0038] Furthermore, a screw 15 is threaded onto the wall of the sleeve 6. The screw 15 is positioned opposite to the limiting block 16, allowing one end of the screw 15 to pass through the sleeve 6 and extend to the end of the limiting block 16. With this structure, when the screw 15 is rotated to press the limiting block 16, the first inclined surface 1601 can be completely pressed into the limiting groove 701. At this time, the sleeve 6 can drive the slide plate 7 to rotate in the forward or reverse direction.

[0039] An annular plate 13 is fixedly sleeved on the outer peripheral wall of the connecting pipe 101, while an annular groove is opened on the inner wall of the sliding plate 7 to slide with the annular plate 13, so that the sliding plate 7 can move vertically relative to the annular plate 13. A limiting spring is provided between the annular plate 13 and the bottom surface of the annular groove. The limiting spring can be sleeved on the outside of the connecting pipe 101. With this structure, when the top rod 12 and the boss 11 are misaligned, the limiting spring can squeeze the sliding plate 7 to move downward, thereby driving the slider 14 to move downward in the connecting pipe 101, which is beneficial to squeeze the cleaning liquid in the tank 1 into the guide pipe 9.

[0040] The aforementioned drainage assembly includes a drainage plate 17 disposed within the inner cavity of the slider 14. The drainage plate 17 contacts the inner wall of the slider 14 and is fixedly connected to the slider 14, as detailed below. Figures 8-9 As shown, the inner wall of the slider 14 is open, while the guide tube 9 has a through-hole 901. This structure allows the slider 14 and the guide tube 9 to communicate with each other. In the initial state, the guide plate 17 is located at the guide hole 901 and can seal the guide hole 901. A vertical positioning groove 902 is provided on the outer peripheral wall of the guide tube 9, and a positioning plate 22 is slidably assembled in the positioning groove 902. The positioning plate 22 is located inside the slider 14 and has... Specifically, the diversion plate 17 contacts the outer wall of the guide tube 9, while the portion of the positioning plate 22 extending into the inner cavity of the slider 14 contacts the inner wall of the slider 14, and the positioning plate 22 and the inner wall of the slider 14 are sealed together. Through this structure, when the slider 14 rotates relative to the guide tube 9, the diversion plate 17 can gradually move away from the positioning plate 22, thereby increasing the space between the diversion plate 17 and the positioning plate 22, so that water in the guide tube 9 can be drawn into the inner cavity of the slider 14 through the diversion hole 901.

[0041] In actual use, rotating the sleeve 6 in the forward direction causes the slide plate 7 to rotate through the cooperation of the limiting block 16 and the limiting groove 701. When the slide plate 7 rotates relative to the pressure ring 10 below it, the push rod 12 can gradually approach the boss 11. The inclined pressing surface 1101 on the boss 11 can push the push rod 12 upward, thereby driving the support rod 8 to move upward. Since the support rod 8 can slide relative to the slider 14 in a single direction, the support rod 8 can rotate relative to the slider 14 and drive the slider 14 to move upward. When the push rod 12 is misaligned with the boss 11, the pressure of the limiting spring... The force can drive the slide plate 7 to move downward, thereby driving the support rod 8 and the slider 14 to move downward. When the slider 14 moves downward in the connecting pipe 101, the cleaning fluid in the tank 1 can be squeezed into the guide pipe 9 through the slider 14, and then discharged through the guide pipe 9 to rinse the patient's ear canal. When the sleeve 6 rotates in the opposite direction and resets, since the end of the limiting block 16 near the limiting groove 701 is set as the first inclined surface 1601, the sleeve 6 will not drive the slide plate 7 to rotate. Repeat the above process. During the reciprocating rotation of the sleeve 6, the cleaning fluid in the tank 1 can be continuously squeezed into the guide pipe 9.

[0042] When the rinsing is almost finished, the screw 15 can be rotated so that it can press the limiting block 16 during its movement, so that the first inclined surface 1601 can be completely within the limiting groove 701. At this time, the sleeve 6 can drive the slide plate 7 to rotate during its reverse rotation. Since the pressure ring 10 is engaged with the connecting pipe 101 through a one-way bearing, the pressure ring 10 can be driven to rotate relative to the connecting pipe 101 through the engagement of the push rod 12 and the boss 11 during the reverse rotation of the slide plate 7. At the same time, the support rod 8 can only rotate in one direction relative to the slider 14, so that the slider 14 can be driven to rotate through the support rod 8 during the reverse rotation of the slide plate 7. Figures 8-9 As shown, when the slider 14 rotates relative to the connecting pipe 101, as the guide plate 17 gradually moves away from the positioning plate 22, the space between the guide plate 17 and the positioning plate 22 gradually increases and forms a negative pressure, so that the cleaning fluid inside the guide pipe 9 can enter the inner cavity of the slider 14 through the guide hole 901, which helps to prevent the cleaning fluid from leaking out from the top of the guide pipe 9.

[0043] In summary, this device, through the compression component, allows the slider 14 to move vertically within the connecting pipe 101 during its reciprocating rotation. When the slider 14 moves downward, it can compress the cleaning fluid in the tank 1 into the guide pipe 9, and then discharge it through the guide pipe 9. Furthermore, the drainage component can draw the cleaning fluid in the guide pipe 9 into the slider 14, thus preventing the cleaning fluid from leaking out through the top of the guide pipe 9.

[0044] like Figures 1-6As shown, in order to rotate the sleeve 6, a bracket 4 is fixedly installed on the top of the tank 1. A grip is provided at the end of the bracket 4 away from the tank 1. This structure facilitates gripping the device. A through groove is opened on the bracket 4, and a sliding rod 3 is slidably assembled in the through groove. Specifically, a crossbar is fixedly installed in the through groove. The crossbar passes through the sliding rod 3 and slides with it. A pull rope 2 is fixed between the sliding rod 3 and the outer wall of the sleeve 6. The end of the pull rope 2 fixed to the sleeve 6 is on the side of the sleeve 6 away from the sliding rod 3. A pulley is installed on the top of the bracket 4 so that the pull rope 2 can pass around the outside of the pulley. In actual use, medical staff can pull the pull rope 2 by pressing the sliding rod 3, thereby driving the sleeve 6 to rotate.

[0045] A fixing ring 5 is fitted on the outside of the sleeve 6, and the fixing ring 5 is fixedly connected to the top of the tank body 1. A guide groove 601 is opened on the outer wall of the sleeve 6, and a guide rod 19 is slidably installed inside the fixing ring 5. The guide rod 19 is slidably engaged with the guide groove 601, and the cross-sections of the guide rod 19 and the guide groove 601 are both T-shaped. A coil spring 20 is provided inside the fixing ring 5, and the two ends of the coil spring 20 are fixedly connected to the guide rod 19 and the inner wall of the fixing ring 5, respectively. Through this structure, the sleeve 6 can move up and down relative to the guide rod 19. Furthermore, when the pull rope 2 is released, the force exerted by the coil spring 20 on the guide rod 19 can drive the sleeve 6 to rotate in the opposite direction and return to its original position.

[0046] Combination Figures 1-11 As shown, two annular retaining rings 1402 are fixedly connected to the top surface of the slider 14. The two retaining rings 1402 are coaxially arranged, and the cross section of the space enclosed by the two retaining rings 1402 is T-shaped. The support rod 8 is set in a T-shape at one end of the slider 14, and the support rod 8 slides between the two retaining rings 1402 at one end of the slider 14. Through this structure, the support rod 8 can drive the slider 14 to move in the vertical direction.

[0047] The top surface of the slider 14 is evenly provided with multiple slots 1401, which are located between two retaining rings 1402. The end face of the support rod 8 near the slot 1401 is provided with an installation groove. A retaining block 21 is slidably assembled in the installation groove. A spring is fixedly provided between the retaining block 21 and the inner end face of the installation groove. The end of the retaining block 21 inserted into the slot 1401 is provided with a second inclined surface 2101. The second inclined surface 2101 is not completely inserted into the slot 1401. Through this structure, the support rod 8 can drive the slider 14 to rotate in a single direction. As described above, when the sleeve 6 drives the slide plate 7 to rotate in the opposite direction, the support rod 8 can drive the slider 14 to rotate relative to the guide tube 9 by using the cooperation of the retaining block 21 and the slot 1401.

[0048] In actual use, the guide pipe 9 and the tank 1 can be fixedly connected by a fixing rod. Specifically, the fixing rod can be set inside the tank 1 or outside the tank 1.

[0049] Combination Figure 5 As shown, an air inlet 102 is provided near the top of the tank 1, and a one-way valve is installed in the air inlet 102, so that external gas can only enter the tank 1 in one direction. Through this structure, when the slider 14 moves upward, it can draw external gas into the tank 1 through the air inlet 102. When the slider 14 moves downward, it can squeeze the cleaning liquid in the tank 1 into the guide pipe 9.

[0050] The inner wall of the sleeve 6 is provided with a groove that slides with the limiting block 16, and a first spring is fixedly provided between the inner end face of the groove and the limiting block 16.

[0051] A stop 18 is provided below the pressure ring 10. The stop 18 is fixedly installed on the outer wall of the connecting pipe 101. This structure helps to support the pressure ring 10.

[0052] In actual use, annular sealing rings are fixedly installed on the outer peripheral wall of slider 14 and the inner wall of slide plate 7, making the seal between slider 14 and the inner wall of connecting pipe 101 more reliable, and the connection between slide plate 7 and connecting pipe 101 more stable, which can prevent slide plate 7 from rotating when sleeve 6 rotates in the opposite direction.
