Specific embodiments

[0032] As Figures 1-10 shown, a flushing device for otorhinolaryngology includes a tank body 1 for storing cleaning liquid. A water pipe can be installed on the tank body 1 to facilitate injecting the cleaning liquid into the tank body 1. Of course, a valve is installed on the water pipe. An integrally formed connecting pipe 101 is provided on the top surface of the tank body 1. A slider 14 is installed inside the connecting pipe 101. The slider 14 is of an overall annular structure and is in sealing fit with the inner wall of the connecting pipe 101. A diversion pipe 9 is provided at the center of the slider 14. Specifically, the diversion pipe 9 is integrally arranged in an L shape. The bottom end of the diversion pipe 9 extends into the tank body 1 and is close to the bottom end. The diversion pipe 9 passes through the slider 14, and the slider 14 is in sealing fit with the diversion pipe 9. When the slider 14 moves downward inside the connecting pipe 101, the slider 14 can squeeze out the cleaning liquid in the tank body 1 through the diversion pipe 9, thereby flushing the patient's ear canal. As an extended solution, the end of the diversion pipe 9 away from the tank body 1 can be provided with a threaded structure or a corresponding clamping structure to facilitate the installation of different pipe fittings and enable flushing of the nasal cavity or ear canal, etc.

[0033] A ring-shaped sliding plate 7 and a pressing ring 10 are sleeved outside the connecting pipe 101. The pressing ring 10 is arranged at a position below the sliding plate 7 and is in cooperation with the connecting pipe 101 through a one-way bearing, so that the pressing ring 10 can only rotate unidirectionally relative to the connecting pipe 101. The sliding plate 7 and the pressing ring 10 are in cooperation through an extrusion assembly. When the sliding plate 7 rotates relative to the pressing ring 10, the extrusion assembly can drive the sliding plate 7 to move upward. The slider 14 and the sliding plate 7 are connected through a support rod 8. Specifically, the support rod 8 is integrally arranged in an L shape. The horizontal section of the support rod 8 is fixedly connected to the sliding plate 7. The vertical section of the support rod 8 is clamped with the slider 14, so that the support rod 8 can rotate unidirectionally relative to the slider 14;

[0034] Further, a sleeve 6 is sleeved outside the skateboard 7. The sleeve 6 is matched with the skateboard 7 through a limiting component, so that the sleeve 6 can drive the skateboard 7 to rotate along a single direction. During actual use, the sleeve 6 can drive the slider 14 to rotate relative to the pressing ring 10, and then drive the skateboard 7 to move upward through the extrusion component. Through the arranged support rod 8, the skateboard 7 can drive the slider 14 in the connecting pipe 101 to move upward. When the slider 14 resets downward, the cleaning liquid in the tank body 1 can be squeezed into the diversion pipe 9, which is beneficial to flushing the patient's ear canal;

[0035] A drainage component is arranged in the inner cavity of the slider 14. When the slider 14 is driven to rotate relative to the diversion pipe 9 through the support rod 8, the cleaning liquid in the diversion pipe 9 can be sucked into the slider 14 through the drainage component.

[0036] As Figures 1-10 shown, the above-mentioned extrusion component includes a top rod 12 arranged on the bottom surface of the skateboard 7 and fixedly connected with the skateboard 7. A boss 11 matched with the top rod 12 is fixedly arranged on the top surface of the pressing ring 10, and the top of the boss 11 is provided with an inclined extrusion surface 1101. Specifically, when in use, multiple groups of the top rod 12 and the boss 11 can be arranged. When the skateboard 7 rotates relative to the pressing ring 10 so that the top rod 12 approaches the boss 11, the top rod 12 can be jacked upward through the inclined extrusion surface 1101, and then drive the skateboard 7 to move upward relative to the connecting pipe 101. When the top rod 12 and the boss 11 are staggered, the skateboard 7 can move downward to reset.

[0037] The limiting component includes a limiting block 16 arranged on the inner wall of the sleeve 6 and elastically connected with the sleeve 6. A plurality of limiting grooves 701 matched with the limiting block 16 are uniformly formed on the outer side wall of the skateboard 7. One end of the limiting block 16 located inside the limiting groove 701 is provided with a first inclined surface 1601. After 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 skateboard 7 to rotate along a single direction;

[0038] Further, a screw rod 15 is threadedly connected to the barrel wall of the sleeve 6. The screw rod 15 is arranged opposite to the limiting block 16, so that one end of the screw rod 15 can pass through the sleeve 6 and extend to the end position of the limiting block 16. Through this structure, when the screw rod 15 is rotated to squeeze the limiting block 16, the first inclined surface 1601 can be completely squeezed into the limiting groove 701. At this time, the sleeve 6 can drive the skateboard 7 to rotate forward or backward.

[0039] An annular plate 13 is fixedly sleeved on the outer peripheral wall of the connecting tube 101, and an annular groove slidably matched with the annular plate 13 is opened on the inner wall of the slide plate 7, so that the slide plate 7 can move in the vertical direction relative to the annular plate 13, and a limiting spring is arranged between the annular plate 13 and the bottom surface of the annular groove. The limiting spring can be sleeved on the outer side of the connecting tube 101. Through this structure, when the push rod 12 is staggered with the boss 11, the slide plate 7 can be squeezed to move downward by the limiting spring, thereby driving the slider 14 to move downward in the connecting tube 101, which is beneficial to squeezing the cleaning liquid in the tank body 1 into the guide tube 9.

[0040] The drainage assembly includes a drainage plate 17 disposed in the inner cavity of the slider 14. The drainage plate 17 is in contact with the inner wall of the slider 14 and is fixedly connected to the slider 14. Figures 8-9 As shown, the inner wall of the slider 14 is in an open state, and a through-flow guide hole 901 is provided at the wall of the guide tube 9. Through this structure, the slider 14 and the guide tube 9 can be connected to 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 at the outer peripheral wall of the guide tube 9, and a positioning plate 22 is slidably mounted in the positioning groove 902. The positioning plate 22 is in the slider 14, which has Specifically, the guide plate 17 is in contact with the outer wall of the guide tube 9, and the portion of the positioning plate 22 extending to the inner cavity of the slider 14 is in contact with 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 guide plate 17 can gradually move away from the positioning plate 22, thereby increasing the space between the guide plate 17 and the positioning plate 22, and can suck the water in the guide tube 9 into the inner cavity of the slider 14 through the guide hole 901.

[0041] In actual use, the sleeve 6 is rotated forward, and the sleeve 6 can drive the slide plate 7 to rotate through the cooperation of the limit block 16 and the limit 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, and the push rod 12 can be pushed up by the inclined extrusion surface 1101 on the boss 11, 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 staggered with the boss 11, the pressure of the limit spring The force can drive the slide plate 7 to move downward, thereby driving the support rod 8 and the slide block 14 to move downward. When the slide block 14 moves downward in the connecting tube 101, the cleaning liquid in the tank body 1 can be squeezed into the guide tube 9 through the slide block 14, and then discharged through the guide tube 9 to flush the patient's ear canal. When the sleeve 6 rotates in the opposite direction and resets, since the end of the limit block 16 close to the limit 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 liquid in the tank body 1 can be continuously squeezed into the guide tube 9.

[0042] When flushing is almost finished, the screw 15 can be rotated so that the screw 15 can squeeze the limit block 16 during its movement, so that the first inclined surface 1601 can be completely in the limit groove 701. At this time, the slide plate 7 can be driven to rotate during the reverse rotation of the sleeve 6. Since the pressure ring 10 cooperates 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 during the reverse rotation of the slide plate 7 through the cooperation between the push rod 12 and the boss 11. At the same time, the support rod 8 can only rotate in one direction relative to the slider 14, so that during the reverse rotation of the slide plate 7, the slider 14 can be driven to rotate through the support rod 8. Figures 8-9 As shown, when the slider 14 rotates relative to the connecting tube 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 tube 9 can enter the inner cavity of the slider 14 through the guide hole 901, which helps to prevent the cleaning fluid from leaking from the top of the guide tube 9.

[0043] To summarize, this device uses an extrusion component to enable the slider 14 to move in the vertical direction in the connecting tube 101 during the reciprocating rotation of the slider 14. When the slider 14 moves downward, the cleaning liquid in the tank body 1 can be squeezed into the guide tube 9, and then discharged through the guide tube 9. In addition, the drainage component can be used to suck the cleaning liquid in the guide tube 9 into the slider 14, thereby preventing the cleaning liquid from leaking through the top of the guide tube 9.

[0044] like Figures 1-6As shown, in order to drive the sleeve 6 to rotate, in this scheme, a bracket 4 is fixedly installed on the top of the tank body 1, and a gripping portion is provided at one end of the bracket 4 away from the tank body 1. This structure is conducive to holding the device, and a through groove is provided on the bracket 4, and a slide bar 3 is slidably installed in the through groove. Specifically, a cross bar is fixedly provided in the through groove, and the cross bar passes through the slide bar 3 and slides with it, and a pull rope 2 is fixed between the slide bar 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 slide bar 3, and a pulley is installed on the top of the bracket 4, so that the pull rope 2 can bypass from the outside of the pulley. In actual use, medical staff can pull the pull rope 2 by pressing the slide bar 3, and then drive the sleeve 6 to rotate through the pull rope 2.

[0045] A fixing ring 5 is sleeved 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 in the fixing ring 5. The guide rod 19 is slidably matched with the guide groove 601, and the cross-sections of the guide rod 19 and the guide groove 601 are both set to be T-shaped. A coil spring 20 is arranged in the fixing ring 5, and the two ends of the coil spring 20 are respectively fixedly connected to the guide rod 19 and the inner wall of the fixing ring 5. Through this structure, the sleeve 6 can move up and down relative to the guide rod 19, and when the pull rope 2 is released, the force of the coil spring 20 on the guide rod 19 can drive the sleeve 6 to rotate in the opposite direction and reset.

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

[0047] A plurality of slots 1401 are evenly arranged on the top surface of the slider 14, and the slots 1401 are located between the two retaining rings 1402, and an installation slot is arranged on the end surface of the support rod 8 close to the slot 1401, and a block 21 is slidably mounted in the installation slot, and a spring is fixedly arranged between the block 21 and the inner end surface of the installation slot, and a second inclined surface 2101 is arranged on the end of the block 21 inserted into the slot 1401, and the second inclined surface 2101 is not fully inserted into the slot 1401. Through this structure, the support rod 8 can drive the slider 14 to rotate in a single direction. According to the above description, 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 utilizing the cooperation between the block 21 and the slot 1401.

[0048] In actual use, the diversion pipe 9 and the tank body 1 can be fixedly connected through a fixing rod. Specifically, the fixing rod can be arranged inside or outside the tank body 1.

[0049] Combined with Figure 5 As shown, an air inlet hole 102 is provided at a position near the top of the tank body 1, and a one-way valve is installed in the air inlet hole 102, so that the external gas can only enter the tank body 1 unidirectionally. With this structure, when the slider 14 moves upward, the external gas can be inhaled into the tank body 1 through the air inlet hole 102, and when the slider 14 moves downward, the cleaning liquid in the tank body 1 can be squeezed into the diversion pipe 9.

[0050] A notch that slidably cooperates with the limit block 16 is provided on the inner wall of the sleeve 6, and a first spring is fixedly arranged between the inner end face of the notch and the limit block 16.
