Description

Technical Field

[0001] This invention relates to the field of nursing device technology, specifically a multifunctional nasal irrigator. Background Technology

[0002] Most commercially available nasal irrigators operate on the Venturi negative pressure spray principle. Due to the high-speed airflow and pump operation, these irrigators are quite noisy during operation. This loud noise can easily cause fear and anxiety in users, especially infants and young children who strongly resist using them. Another drawback is the low spray flow rate, typically only 10-20 ml / min. This insufficient flow rate prevents the cleaning solution from reaching deep into the nasal cavity, failing to achieve the desired cleaning effect. Therefore, a multi-functional nasal irrigator is needed.

[0003] According to a public notice of a multifunctional nasal irrigator (publication number: CN205988403U), the above application allows for the corresponding configuration of the nozzle's through-hole with a misting hole, small-diameter hole, or large-diameter hole, thereby changing the state of the sprayed liquid to achieve different cleaning effects without the need to replace the nozzle, thus realizing the effect of one nozzle serving multiple purposes.

[0004] However, in actual use, the nasal tube of the aforementioned device, once inserted into the patient's nostril, only covers a limited area with the sprayed cleaning solution. Furthermore, the device requires continuous manual adjustment to ensure even and thorough cleaning of the nasal cavity. Since the nostrils are highly sensitive, even slight mishaps can easily cause discomfort or sneezing. In such cases, the nasal irrigator may cause injury to the patient due to head movement. Therefore, we propose a multifunctional nasal irrigator. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional nasal irrigator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional nasal irrigator, comprising a water tank, the water tank being fixedly connected to the input end of a water pump via a conduit, the output end of the water pump being fixedly connected to the bottom end of an irrigating head via another set of conduits, a nasal tube being fixedly installed on the top of the irrigating head, a silicone collar being provided on the top of the irrigating head, the water pump being electrically connected to a controller and a power supply via a wire, and a spray assembly being provided inside the nasal tube, the spray assembly comprising:

[0007] A sleeve is slidably connected to the top inner wall of the nose tube, and a nozzle is provided on the arc-shaped outer wall of the sleeve. A top cover is fixedly installed on the top of the sleeve. The top of a connecting rod is fixedly connected to the top inner wall of the nose tube. A sleeve is fitted on the bottom outer wall of the connecting rod. A connecting cover is fixedly connected to the bottom of the sleeve. A limiting ring is fixedly installed on the arc-shaped outer wall of the sleeve, and the limiting ring is located inside the connecting cover.

[0008] A transmission rod is rotatably mounted on the inner wall of the top cover. A drive gear passes through the transmission rod and is fixedly connected to the transmission rod. A driven gear is rotatably mounted on the inner wall of the top cover. A rotating shaft passes through and is slidably connected to the inner wall of the transmission rod. An impeller is fixedly connected to the bottom end of the rotating shaft.

[0009] A fixing sleeve is fixedly installed on the inner wall of the nasal tube, and a return spring is provided between the bottom end of the connecting rod and the connecting cover.

[0010] Preferably, the top of the nasal tube has a circular hole with a diameter that matches the outer diameter of the sleeve, and the outer wall of the top of the nasal tube has a circular groove that can accommodate the top cover, so that the top cover and the sleeve can be stored in the internal space of the nasal tube in the initial state, so that the nozzle will not be blocked by foreign objects in the patient's nasal cavity during the process of the nasal tube being inserted into the patient's nostril.

[0011] Preferably, the connecting cover has a circular annular groove inside that matches the size of the limiting ring, and the limiting ring is located inside the connecting cover so that the limiting ring can only rotate relative to the connecting cover, and will not have relative displacement in the vertical direction.

[0012] Preferably, the top cover has an internal cavity, which is disc-shaped. The inner circular surface of the cavity has teeth that mesh with the driven gear to achieve transmission. This allows the sleeve to rotate at a lower speed than the transmission rod when the transmission rod rotates, in conjunction with the driving gear and the driven gear.

[0013] Preferably, the inner wall of the transmission rod is provided with a transmission hole that matches the outer diameter of the shaft, and the arc-shaped outer wall of the shaft is provided with a corresponding strip-shaped limiting block. At the same time, the inner surface of the transmission hole is provided with a limiting groove that matches the strip-shaped limiting block, so that the shaft and the transmission rod can only be displaced in the vertical direction and will not rotate relative to each other.

[0014] Preferably, the sleeve is provided with a flow-dispersing component, which includes a lever. The end of the lever is fixedly installed on the arc-shaped outer wall of the transmission rod. A fixing post is fixedly installed on the inner surface of the nozzle. A flow-dispersing plate is rotatably connected through the fixing post. The end of a spiral spring is fixedly connected to the arc-shaped outer wall of the fixing post. Flow-dispersing grooves are formed on the upper and lower outer walls of the flow-dispersing plate. A separating slider is slidably connected to the inner wall of the flow-dispersing groove.

[0015] Preferably, the lever and the nozzle are arranged in the same plane, and the end of the lever is spherical. The sidewall edges of the spoiler are all chamfered so that the lever can better move the spoiler as the transmission rod rotates, avoiding jamming between the lever and the spoiler.

[0016] Preferably, the spoiler has a circular inner groove on its side wall with a diameter larger than the outer diameter of the spiral spring, and the other end of the spiral spring is fixedly connected to the bottom inner surface of the circular inner groove. Specifically, the spiral spring is sleeved on the arc-shaped outer wall of the fixed column, so that the spiral spring can always provide a stable transmission effect for the spoiler.

[0017] Preferably, the inner surface of the turbulence channel is provided with an inclined groove adapted to the size of the separating slider, and the separating slider is disposed in the inclined groove. A magnetic sheet is provided on the inner surface of the end of the inclined groove, and magnetic blocks are respectively provided at both ends of the separating slider. The magnetic sheet and the magnetic blocks have the same magnetism, so that the impact of the nasal cleaning fluid can cause the separating slider to reciprocate within the inclined groove.

[0018] Preferably, a spiral drainage groove is provided on the arc-shaped inner surface of the sleeve, and the top of the spiral drainage groove is flush with the bottom of the nozzle to better guide the nasal cleaning fluid flushed into the sleeve and spray it out from the nozzle.

[0019] Compared with the prior art, the present invention provides a multifunctional nasal irrigator with the following beneficial effects:

[0020] 1. This multifunctional nasal irrigator, designed to reduce manual operation and enhance nasal cleaning effectiveness, incorporates a spray assembly. The impact flow of the nasal cleaning solution drives the impeller to rotate. Combined with drive and driven gears, the sleeve continues to rotate after extending out of the nasal tube and exposing the nozzle. This allows the nozzle to continuously and slowly rotate while spraying nasal cleaning solution, improving the cleaning effect on the patient's nasal cavity. This eliminates the need for manual control, preventing excessive stimulation and potential harm to the patient, and ensuring the safety and comfort of the nasal cleaning procedure.

[0021] 2. In order to better improve the cleaning effect of the nasal cleaning solution sprayed from the nozzle, this multi-functional nasal irrigator is equipped with a turbulence-dispersing component. With the periodic rotation of the transmission rod, the turbulence plate swings up and down periodically. This, combined with the separating slider, allows the flow of the nasal cleaning solution to be turbulent and diffused, making it more dispersed and thus cleaning a larger area, thereby improving the working effect of the device.

[0022] 3. This multifunctional nasal irrigator features a spiral drainage groove on the arc-shaped inner surface of the sleeve to better drain the nasal cleaning solution flushed into the sleeve, allowing it to be sprayed out from the nozzle to clean the patient's nasal cavity.

[0023] 4. This multi-functional nasal irrigator uses a positive pressure water pump to irrigate the nose, which reduces noise and improves overall comfort, avoiding patient anxiety and rejection, and preventing disruption of the nasal irrigation process. Attached Figure Description

[0032] like Figure 1-7 As shown, the present invention provides a technical solution: a multifunctional nasal irrigator, including a water tank 27, which is fixedly connected to the input end of a water pump 26 via a conduit 25. The output end of the water pump 26 is fixedly connected to the bottom end of a nasal irrigation head 1 via another set of conduits 25. A nasal tube 2 is fixedly installed on the top of the nasal irrigation head 1, and a silicone collar 3 is provided on the top of the nasal irrigation head 1. The water pump 26 is electrically connected to a controller 28 and a power supply device 29 via wires. A spray assembly is provided inside the nasal tube 2, which includes a sleeve 4. The sleeve 4 is slidably connected through the top inner wall of the nasal tube 2. A nozzle 5 is provided on the arc-shaped outer wall of the sleeve 4. A top cover 6 is fixedly installed on the top of the sleeve 4. The top end of the connecting rod 7 is fixedly connected, and the bottom outer wall of the connecting rod 7 is fitted with a sleeve 8. The bottom end of the sleeve 8 is fixedly connected with a connecting cover 9. A limit ring 10 is fixedly installed on the arc-shaped outer wall of the sleeve 4. The limit ring 10 is located inside the connecting cover 9. The top end of the transmission rod 11 is rotatably installed on the inner wall of the top cover 6. The transmission rod 11 passes through the drive gear 12 and is fixedly connected to the transmission rod 11. The driven gear 13 is rotatably installed on the inner wall of the top cover 6. The inner wall of the transmission rod 11 passes through and is slidably connected with a rotating shaft 14. The bottom end of the rotating shaft 14 is fixedly connected with an impeller 15. A fixing sleeve 16 is fixedly installed on the inner wall of the nose tube 2. A return spring 17 is provided between the bottom end of the connecting rod 7 and the connecting cover 9.

[0033] In one embodiment of the present invention, the water tank 27 stores nasal cleaning solution. Specifically, the nasal cleaning solution is generally 0.9% saline solution. The water tank 27 is an open container at the top, and its opening can accommodate the catheter 25 extending into the bottom of the water tank 27. The outer edge of the opening of the water tank 27 has a fixing buckle for securing the water tank 27. Furthermore, an air inlet is provided at the top of the water tank 27 to prevent negative pressure from forming inside the water tank 27 during pumping, which would affect the normal extraction of the nasal cleaning solution. Additionally, the nasal tube 2 itself is made of silicone material. To avoid excessive stimulation to the patient's nasal cavity when the nasal tube 2 is inserted, thus affecting the normal operation of the nasal irrigation, the water pump 26 uses positive pressure water output for nasal irrigation, greatly reducing the overall noise of the device and avoiding patient discomfort. Simultaneously, the top of the nasal tube 2 has a circular hole with a diameter matching the outer diameter of the sleeve 4, and the outer wall of the top of the nasal tube 2 has a circular groove to accommodate the top cover 6. This facilitates the initial insertion of the top cover 6 and the sleeve 4 into the internal space of the nasal tube 2, ensuring that the nasal tube 2 is not disturbed during insertion into the patient's nostril. In case of blockage of the nozzle 5 due to foreign objects in the patient's nasal cavity, the nozzle 5 is provided in three sets, which are evenly distributed in a circular array on the arc-shaped outer wall of the sleeve 4. This allows the nozzle 5 to continuously spray the surrounding area during the continuous rotation of the sleeve 4, ensuring the smooth discharge of nasal cleaning solution. Furthermore, a circular insertion hole with a diameter matching the outer diameter of the connecting rod 7 is provided at the center of the sleeve 8, allowing the connecting rod 7 to move vertically within the inner wall of the sleeve 8. Simultaneously, the return spring 17 is provided... The spring 17 is placed in the central cavity of the sleeve 8 so that the return spring 17 can always provide a stable transmission effect for the connecting rod 7. In addition, the interior of the connecting cover 9 is provided with a circular annular groove that matches the size of the limiting ring 10. The limiting ring 10 is located inside the connecting cover 9 so that the limiting ring 10 can only rotate relative to the connecting cover 9 and will not be displaced relative to the vertical direction. Thus, when the top cover 6 is flushed with nasal cleaning fluid from the nasal tube 2, the limiting ring 10 will drive the connecting cover 9 and the sleeve 8 to move toward the top of the nasal tube 2.

[0034] In an embodiment of the present invention, the top cover 6 has an internal cavity for mounting the drive gear 12 and the driven gear 13. The driven gear 13 meshes with the drive gear 12 to achieve transmission. The cavity is disc-shaped; specifically, the inner circular surface of the cavity has teeth that mesh with the driven gear 13 to achieve transmission. This allows the sleeve 4 to rotate at a lower speed than the drive rod 11 when the transmission rod 11 rotates, in conjunction with the drive gear 12 and the driven gear 13. Specifically, a certain speed difference is always maintained between the sleeve 4 and the transmission rod 11. Furthermore, the inner wall of the transmission rod 11 has a transmission hole that matches the outer diameter of the rotating shaft 14, and the arc-shaped outer wall of the rotating shaft 14 is provided with… There are corresponding strip-shaped limiting blocks, and the inner surface of the transmission hole is provided with a limiting groove that matches the strip-shaped limiting blocks. This allows the rotating shaft 14 and the transmission rod 11 to only have relative displacement in the vertical direction, without relative rotation. This allows the impeller 15 to rotate synchronously when it starts to rotate due to the water flow in the nose tube 2, driving the rotating shaft 14 and the transmission rod 11 to rotate. Furthermore, the rotating shaft 14 passes through the fixed sleeve 16 and is rotatably connected to the fixed sleeve 16. A transmission structure similar to the limiting ring 10 and the connecting cover 9 is provided between the fixed sleeve 16 and the rotating shaft 14, so that the fixed sleeve 16 will not affect the rotation of the rotating shaft 14. At the same time, it can also provide a mounting position for the rotating shaft 14, ensuring that it can provide stable transmission for the transmission rod 11.

[0035] In addition, in order to better improve the cleaning effect of the nasal cleaning fluid sprayed from the nozzle 5, a turbulence component is provided inside the sleeve 4. The turbulence component includes a lever 18. The end of the lever 18 is fixedly installed on the arc-shaped outer wall of the transmission rod 11. A fixing post 19 is fixedly installed on the inner surface of the nozzle 5. A turbulence plate 20 is rotatably connected through the fixing post 19. The end of a spiral spring 21 is fixedly connected to the arc-shaped outer wall of the fixing post 19. Turbulence grooves 22 are opened on the upper and lower outer walls of the turbulence plate 20. A separating slider 23 is slidably connected to the inner wall of the turbulence groove 22.

[0036] In an embodiment of the present invention, three sets of levers 18 are provided, and the three sets of levers 18 are evenly distributed in a circumferential array on the arc-shaped outer wall of the transmission rod 11. The levers 18 and the nozzle 5 are arranged in the same plane, and the ends of the levers 18 are spherical. The edges of the sidewalls of the spoiler 20 are chamfered to allow the levers 18 to better move the spoiler 20 as the transmission rod 11 rotates, preventing the levers 18 from jamming against the spoiler 20. Additionally, the sidewalls of the spoiler 20 have a diameter... A circular inner groove larger than the outer diameter of the spiral spring 21 is provided, and the other end of the spiral spring 21 is fixedly connected to the bottom inner surface of the circular inner groove. Specifically, the spiral spring 21 is sleeved on the arc-shaped outer wall of the fixed post 19, so that the spiral spring 21 can always provide a stable transmission effect for the spoiler 20. In addition, multiple sets of spoiler grooves 22 are provided, and the multiple sets of spoiler grooves 22 are evenly distributed on the upper and lower outer walls of the spoiler 20. Furthermore, the spoiler grooves 22 are shallower on the side closer to the center of the sleeve 4 and deeper on the side farther away from the center of the sleeve 4. The design allows the nasal cleaning fluid discharged from the nozzle 5 to be better affected by the interference of the turbulence channel 22, resulting in branching. The nasal cleaning fluid within the turbulence channel 22 maintains its spray direction, while the nasal cleaning fluid guided at other locations on the turbulence plate 20 is widely dispersed. This ensures both the spraying effect of the nasal cleaning fluid and expands its cleaning range, improving the cleaning effect of the device. In addition, the inner surface of the turbulence channel 22 has an inclined groove adapted to the size of the separating slider 23, and the separating slider 23 is positioned within this inclined groove. Specifically, a magnetic sheet is provided on the inner surface of the inclined chute end, and magnetic blocks are provided at both ends of the separating slider 23. The magnetic sheet and the magnetic blocks have the same magnetism. This means that when the lever 18 periodically moves the baffle 20, the nasal cleaning fluid will impact the separating slider 23 with different forces. However, after the impact ends, it will reset under the repulsive force of the magnetic blocks and magnetic sheets. This can better turbulence and diffusion of the nasal cleaning fluid, making it more dispersed, thereby cleaning a larger area and improving the working effect of the device.

[0037] In addition, to ensure that the nasal cleaning solution can be better sprayed outward from the horizontal nozzle 5 during spraying, a spiral drainage groove 24 is provided on the arc-shaped inner surface of the sleeve 4, and the spiral direction of the spiral drainage groove 24 is consistent with the rotation direction of the sleeve 4. Furthermore, the top of the spiral drainage groove 24 is flush with the bottom of the nozzle 5 to better drain the nasal cleaning solution flushed into the sleeve 4 and spray it out from the nozzle 5 to clean the patient's nasal cavity.

[0038] In this invention, during use, the nasal tube 2 is inserted into the patient's nasal cavity. The power supply device 29 is then activated, and the water pump 26 is started via the operating controller 28. This allows the nasal cleaning solution in the water tank 27 to enter the cleaning head 1 through the conduit 25, pass through the internal cavity of the nasal tube 2, and then flow into the sleeve 4. Due to the impact and pressure of the nasal cleaning solution, the sleeve 4 extends outward from the nasal tube 2, exposing the nozzle 5. The nasal cleaning solution is then sprayed outward from the nozzle 5 and enters the patient's nasal cavity for rinsing. Simultaneously, to reduce manual operation and improve the cleaning effect on the patient's nasal cavity, a spray assembly is provided. The impact flow of the nasal cleaning solution drives the impeller 15 to rotate. In conjunction with the driving gear 12 and driven gear 13, the sleeve 4 continues to rotate after extending out of the nasal tube 2 and exposing the nozzle 5, thus allowing the nozzle 5 to spray outward. When continuously spraying nasal cleaning fluid, it can rotate slowly 360 degrees to improve the cleaning effect on the patient's nasal cavity. It does not require the operator to manually rotate continuously, avoiding excessive stimulation to the patient, which may cause harm and affect the safety and comfort of the nasal cleaning operation. In addition, in order to further improve the cleaning effect of the nasal cleaning fluid sprayed from nozzle 5, a baffle component is set. With the periodic rotation of the lever 18 and the transmission rod 11, the baffle 20 swings up and down periodically. This, together with the separating slider 23, allows the flow of nasal cleaning fluid to be turbulent and diffused, making it more dispersed and cleaning a larger area, thus improving the working effect of the device. Furthermore, a spiral drainage groove 24 is set on the arc-shaped inner surface of the sleeve 4 to better guide the nasal cleaning fluid flushed into the sleeve 4 and spray it out from nozzle 5 to clean the patient's nasal cavity.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
