Description

Technical Field

[0001] This invention relates to the field of nasal care devices, specifically, to an adaptive nasal irrigator. Background Technology

[0002] To the applicant's knowledge, the closest prior art is primarily electric nasal irrigators or nasal irrigation devices with flexible nozzles. These devices typically include a reservoir, a pump, control circuitry, and a nasal nozzle, through which saline solution or other irrigating fluid is delivered into the nasal cavity via the pump. Some products may feature flexible nozzles, replaceable nozzles, multi-hole nozzles, or flow rate adjustment functions to improve user comfort and suit different user groups, including adults and children.

[0003] The advantages of the aforementioned existing technologies are that they are simple in structure, easy to use, and low in cost, and can meet the general needs of nasal cleaning and daily care; the soft nozzle and flow adjustment function can also reduce the irritation caused by the hard nozzle to a certain extent.

[0004] However, existing technologies still have shortcomings: First, the nozzle direction is mostly fixed, requiring users to manually adjust the angle and insertion depth, making it difficult to provide limited adaptive guidance based on the morphology of the nasal inlet and the superficial nasal vestibule, which can easily lead to problems such as jet deflection and localized direct jetting of sensitive areas. Second, most devices use a single-path liquid supply, typically entering the flushing state immediately after startup, making it difficult to achieve gentle pre-wetting, effective main flushing, and a gentle finish. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive nasal irrigator to solve the problems existing in the prior art.

[0006] The object of this invention is achieved as follows: an adaptive guided nasal irrigator, comprising:

[0007] A handheld main unit;

[0008] The control unit is located within the main unit;

[0009] A liquid storage tank located on the main unit;

[0010] The liquid supply drive mechanism, controlled by the control unit, has its inlet connected to the liquid storage tank and its outlet connected to a selectable pre-wetting pipeline and a main flushing pipeline. The pre-wetting pipeline is used before the main flushing pipeline, and the output flow rate of the main flushing pipeline is greater than the output flow rate of the pre-wetting pipeline.

[0011] The nozzle module is equipped with a host interface seat located on the front side of the host body. Both the nozzle module and the host interface seat have two mutually separated channels. The pre-wetting pipeline and the main flushing pipeline are respectively connected to the two channels of the host interface seat. The nozzle module and the host interface seat are detachably spliced ​​together. The two channels of the host interface seat are respectively connected to the two channels of the nozzle module.

[0012] The nozzle module is configured as a passive oscillation structure that generates a limited angle after being squeezed by the contour of the nostril inlet.

[0013] Furthermore, the output side of the nozzle module is provided with a floating jet core, which has two output channels that are respectively connected to the wetting pipeline and the main flushing pipeline.

[0014] Furthermore, the outer side of the floating jet core is fixedly covered with a guide layer for guiding during insertion into the nasal cavity.

[0015] Furthermore, a flexible conforming layer is fixedly affixed to the outside of the guide layer for flexible contact with the shallow part of the nostril entrance. The nozzle module is provided with a pre-wetting outlet and a main flushing outlet. The pre-wetting outlet and the main flushing outlet are respectively connected to the pre-wetting pipeline and the main flushing pipeline. Both the pre-wetting outlet and the main flushing outlet penetrate the conforming layer and the guide layer. The hardness of the conforming layer is lower than that of the guide layer.

[0016] Furthermore, the nozzle module includes:

[0017] A dual-lumen flexible liquid guide tube, which has a first lumen and a second lumen;

[0018] A dual-channel liquid supply seat is fixedly installed on the front side of the host interface seat, which has a pre-wetting upward channel and a main flushing upward channel;

[0019] The dual-cavity flexible liquid guide tube is connected between the dual-channel liquid supply seat and the floating jet core. The first cavity is connected to the pre-wetting upward channel, and the second cavity is connected to the main flushing upward channel.

[0020] Furthermore, the dual-lumen flexible liquid guide tube is configured as a dual-lumen tube structure with elastic reset and cavity cross-section retention functions.

[0021] Furthermore, the floating jet core is provided with a pre-wetting diversion chamber and a main flushing diversion chamber, which are respectively connected to the pre-wetting outlet and the main flushing outlet.

[0022] Furthermore, a depth-limiting buffer shoulder, located outside the nasal cavity, is fixed to the front side of the dual-channel liquid supply seat to limit the insertion depth of the irrigator.

[0023] Furthermore, the dual-channel liquid supply base of the nozzle module has a pair of hollow plugs. The hollow cavities of the two plugs are respectively connected to the pre-wetting upward channel and the main flushing upward channel. The two plugs of the dual-channel liquid supply base are detachably plugged into the two channels of the host interface base and are respectively connected to the two channels of the host interface base.

[0024] Furthermore, it also includes a main switch button, a first output button, a second output button, and an adjustment knob located on the outer wall of the main body, and the control unit is electrically connected to the main switch button, the first output button, the second output button, and the adjustment knob;

[0025] The liquid supply drive mechanism is installed inside the main body. The main body is provided with a pre-wetting liquid supply pipe and a main flushing liquid supply pipe. The pre-wetting liquid supply pipe and the main flushing liquid supply pipe serve as the pre-wetting pipeline and the main flushing pipeline, respectively, and are respectively provided with a pre-wetting solenoid valve and a main flushing solenoid valve.

[0026] The first output button and the second output button are used to control the pre-wetting solenoid valve and the main flushing solenoid valve, respectively. The first output button and the second output button are used to open the pre-wetting pipeline and the main flushing pipeline, respectively. The adjustment knob is used to fine-tune the flow rate of the pre-wetting pipeline and the main flushing pipeline.

[0027] In summary, this solution integrates the functions of contact deformation guidance, dual-chamber repositioning and liquid supply, staged low-irritation flushing, and pressure regulation.

[0028] The beneficial effects of this invention are as follows:

[0029] Compared with existing fixed nozzles, the present invention improves the problems of jet deflection and local irritation by using a guide layer, a compliance layer and a floating jet core to cause the nozzle to passively deflect at a limited angle after being squeezed by the contour of the nostril inlet.

[0030] By using pre-wetting lines and main flushing lines, a phased liquid supply process can be achieved, which involves first pre-wetting at a low flow rate, then performing main flushing at a higher flow rate, and finally gently fading the solution. The flow rate during the pre-wetting stage is lower than that during the main flushing stage, and the flow rate during the main flushing stage can be adjusted according to adult, child, or sensitive modes.

[0031] Because of the double-lumen flexible liquid guide tube, which is designed as a medical spring tube, the floating jet core can maintain the effect of continuous two-way liquid supply without crossflow even when it is in a swaying state.

[0032] In summary, compared with the prior art, the present invention has the advantages of better nozzle compatibility, less irritation during startup, more controllable rinsing process, more stable liquid supply from the moving nozzle, and higher safety, and is especially suitable for children, people with nasal sensitivities, and daily nasal care scenarios.

Detailed Implementation

[0038] The following will refer to the appendices in the embodiments of the present invention. Figure 1-4 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] The existing technology has the following shortcomings: 1. The nozzle direction is mostly fixed, mainly relying on the user to manually adjust the angle and insertion depth. It is difficult to make limited adaptive guidance according to the shape of the nasal inlet and the superficial nasal vestibule, which can easily lead to problems such as spray deviation and local direct impact on sensitive areas; 2. Most devices use a single path for liquid supply, and usually enter the flushing state after startup. They lack independent pre-wetting branches and main flushing branches, making it difficult to achieve gentle pre-wetting, effective main flushing, and gentle finish; 3. When the nozzle is too close to the nasal inlet or the liquid outlet at the front end is blocked, it may cause local pressure to rise, causing swelling, backflow, or discomfort; 4. Existing nozzles only adapt to different people by size or material hardness, and lack the means to coordinate the adjustment of nozzle structure and liquid supply parameters.

[0040] Therefore, it is necessary to provide a nasal irrigator that combines shallow passive guidance at the inlet, dual-branch staged fluid supply, and pressure relief protection to improve adaptability, comfort, and safety.

[0041] like Figure 1-2 As shown, an adaptive guided nasal irrigator is provided, comprising:

[0042] Handheld main unit 1;

[0043] Control unit 4 is located inside the main unit 1;

[0044] Liquid storage tank 2 is located on the main body 1;

[0045] The liquid supply drive mechanism 3, controlled by the control unit 4, has its inlet connected to the liquid storage tank 2, and its outlet connected to a selectable pre-wetting pipeline and a main flushing pipeline. The pre-wetting pipeline is used before the main flushing pipeline, and the output flow rate of the main flushing pipeline is greater than the output flow rate of the pre-wetting pipeline.

[0046] The nozzle module 5 is equipped with a main unit interface seat 6 located on the front side of the main unit body 1. Both the nozzle module 5 and the main unit interface seat 6 have two separate channels. The pre-wetting pipeline and the main flushing pipeline are respectively connected to the two channels of the main unit interface seat 6. The nozzle module 5 and the main unit interface seat 6 are detachably spliced ​​together, and the two channels of the main unit interface seat 6 are respectively connected to the two channels of the nozzle module 5.

[0047] Among them, the nozzle module 5 is configured as a passive oscillation structure that generates a limited angle after being squeezed by the contour of the nostril entrance.

[0048] The fluid supply drive mechanism 3 can preferably be configured as a medical fluid pump to generate infusion power.

[0049] The aforementioned liquid storage tank 2 is detachably connected to the tail of the main body 1 and can be replenished with rinsing liquid. The suction pipe 25 is fixed to the inlet of the liquid supply drive mechanism 3. After the liquid storage tank 2 is connected to the tail of the main body 1, the suction pipe 25 extends into the liquid storage tank 2, so that the liquid supply drive mechanism 3 can draw the cleaning liquid in the liquid storage tank 2.

[0050] As a preferred control scheme, the flusher also includes a main switch button 21, a first output button 22, a second output button 23 and an adjustment knob 24 located on the outer wall of the main body 1. The control unit 4 is electrically connected to the main switch button 21, the first output button 22, the second output button 23 and the adjustment knob 24.

[0051] The aforementioned liquid supply drive mechanism 3 is installed inside the main body 1. The main body 1 is equipped with a pre-wetting liquid supply pipe 7 and a main flushing liquid supply pipe 8. The pre-wetting liquid supply pipe 7 and the main flushing liquid supply pipe 8 serve as the pre-wetting pipeline and the main flushing pipeline, respectively, and are equipped with a pre-wetting solenoid valve 71 and a main flushing solenoid valve 81, respectively. As an optional solution, the diameter of the pre-wetting liquid supply pipe 7 can be smaller than the diameter of the main flushing liquid supply pipe 8, and the flow rate of the pre-wetting liquid supply pipe 7 can be smaller than the flow rate of the main flushing liquid supply pipe 8.

[0052] The first output button 22 and the second output button 23 are used to control the pre-wetting solenoid valve 71 and the main flushing solenoid valve 81, respectively. The first output button 22 and the second output button 23 are also used to open the pre-wetting pipeline and the main flushing pipeline, respectively. The adjusting knob 24 is used to fine-tune the flow rate of the pre-wetting pipeline and the main flushing pipeline, controlling the spray pressure of the flushing fluid to prevent pressure overload from causing swelling, backflow, or discomfort. The setting corresponding to the second output button 23 is higher than the setting corresponding to the first output button 22. Pressing the first output button 22 and the second output button 23 allows selection of the output power of the liquid supply drive mechanism 3. During main flushing, the output power setting of the liquid supply drive mechanism 3 is significantly higher than that during pre-wetting.

[0053] The output side of the above-mentioned nozzle module 5 is provided with a floating jet core 13, which has two output channels that are respectively connected to the wetting pipeline and the main flushing pipeline.

[0054] The floating jet core 13 is fixedly covered with a guide layer 18 for guiding during insertion into the nasal cavity. A flexible compliance layer 19 is fixedly covered with the guide layer 18 for flexible contact with the shallow part of the nostril entrance. The compliance layer 19 is softer than the guide layer 18, that is, the hardness of the compliance layer 19 is lower than that of the guide layer 18. The compliance layer 19 is more easily deformed than the guide layer 18. The nozzle module 5 is provided with a pre-wetting outlet 16 and a main flushing outlet 17. The pre-wetting outlet 16 and the main flushing outlet 17 are respectively connected to the pre-wetting pipeline and the main flushing pipeline. Both the pre-wetting outlet 16 and the main flushing outlet 17 penetrate the compliance layer 19 and the guide layer 18 to facilitate liquid discharge.

[0055] The above-mentioned nozzle module 5 includes:

[0056] A dual-lumen flexible liquid guide tube 12 has a first cavity 12a and a second cavity 12b;

[0057] The dual-channel liquid supply seat 9, which is fixedly installed on the front side of the host interface seat 6, has a pre-wetting upward channel 10 and a main flushing upward channel 11.

[0058] The dual-cavity flexible liquid guide tube 12 is connected between the dual-channel liquid supply seat 9 and the floating jet core 13. The first cavity 12a is connected to the pre-wetting upward channel 10, and the second cavity 12b is connected to the main flushing upward channel 11.

[0059] The aforementioned dual-lumen flexible fluid guide tube 12 is designed as a dual-lumen tube structure with elastic reset and cavity cross-section retention functions. As one of the preferred options, the aforementioned dual-lumen flexible fluid guide tube 12 is a medical spring tube (a professional term in the field of medical devices). The possibility of selecting other materials is not excluded; the medical spring tube is just one preferred option.

[0060] Medical spring tubing is an existing medical tubing material with good elasticity, widely used in the medical industry. It involves embedding a spring within the existing medical tubing, and the elastic modulus of the spring can be determined according to requirements. The technical advantage of using a double-lumen flexible fluid guide tube 12 as a medical spring tubing is that even when bent, the tube body does not exhibit significant radial deformation, possessing sufficient mechanical strength to maintain unobstructed flow even during bending deformation. Furthermore, after unloading, the double-lumen flexible fluid guide tube 12 automatically returns to its original position thanks to its spring element.

[0061] The floating jet core 13 is provided with a pre-wetting diversion chamber 14 and a main flushing diversion chamber 15. The pre-wetting diversion chamber 14 and the main flushing diversion chamber 15 are respectively connected to the pre-wetting outlet 16 and the main flushing outlet 17.

[0062] Compared with existing fixed nozzles, this solution uses a guide layer 18, a compliance layer 19, and a floating jet core 13 to cause the nozzle to passively deflect at a limited angle after being squeezed by the nostril inlet contour, thereby improving the problems of jet deflection and local irritation.

[0063] By using pre-wetting lines and main flushing lines, a phased liquid supply process can be achieved, which involves first pre-wetting at a low flow rate, then increasing the flow rate for main flushing, and finally gently fading the flush. The flow rate during the pre-wetting stage is less than that during the main flushing stage, and the flow rate during the pre-wetting stage can be 10%–50% of that during the main flushing stage (this percentage can be set as needed). The flow rate during the main flushing stage can be adjusted according to adult, child, or sensitive modes.

[0064] Because of the double-lumen flexible liquid guide tube 12, which is preferably a medical spring tube, the floating jet core 13 can still maintain the effect of continuous two-way liquid supply without crossflow even when it is in a swing state.

[0065] When subjected to force, the dual-lumen flexible liquid guide tube 12 bends and generates an elastic restoring torque, which causes the floating jet core 13 at its front end to twist at a certain angle. After being removed from the nasal cavity, the dual-lumen flexible liquid guide tube 12 resets, and the elastic restoring torque drives the floating jet core 13 back to its initial center position.

[0066] The aforementioned dual-channel liquid supply seat 9 has a depth-limiting buffer shoulder 20 fixed to its front side, located outside the nasal cavity, to limit the insertion depth of the irrigator. During use, the depth-limiting buffer shoulder 20 only axially abuts against the nasal inlet to limit the insertion depth of the irrigator into the nasal cavity. During the deformation of the dual-lumen flexible liquid guide tube 12, the dual-channel liquid supply seat 9 and the depth-limiting buffer shoulder 20 remain relatively fixed. The dual-lumen flexible liquid guide tube 12 and the floating jet core 13, located in front of the depth-limiting buffer shoulder 20, form a movable part, and the depth-limiting buffer shoulder 20 does not enter the range of motion of the floating jet core 13.

[0067] like Figure 3 As shown, as a preferred modular design scheme of the nozzle module 5, the dual-channel liquid supply base 9 of the nozzle module 5 has a pair of hollow plugs 9a. The hollow cavities of the two plugs 9a are respectively connected to the pre-wetting upward channel 10 and the main flushing upward channel 11. The two plugs 9a of the dual-channel liquid supply base 9 are respectively detachably plugged into the two channels of the host interface base 6 and are respectively connected to the two channels of the host interface base 6.

[0068] When using it, follow these steps:

[0069] The nozzle module 5 is placed in the shallow part of the nostril entrance. The conforming layer 19 first makes flexible contact with the nostril entrance. The guide layer 18 generates a yaw torque after being squeezed asymmetrically by the nasal vestibule contour, which drives the floating jet core 13 to deflect at a small angle, such as 3°–20°, preferably 5°–15°, to adjust the jet direction.

[0070] Then, the control unit 4 first opens the pre-humidification tubing and sprays out liquid at a low flow rate to moisten the nasal mucosa and secretions;

[0071] Close the pre-wetting branch and open the main flushing branch to perform the main flushing. The main flushing spray flow rate is higher than the pre-wetting spray flow rate.

[0072] At the end, reduce the main flush flow rate and switch back to the low-flow pre-wetting branch.

[0073] During the above process, a pressure closed-loop control mode can be set: when the main flushing is performed, if the main flushing jet pressure of the nozzle module 5 increases sharply, the opening of the main flushing valve solenoid valve 81 will be automatically reduced, or the pre-wetting solenoid valve 71 will be opened to activate the pre-wetting bypass.

[0074] The innovation of this solution lies in the fact that the floating jet core 13 is not a fixed liquid outlet, but is designed as an adaptively adjustable structure. When it enters the nasal cavity, it will make adaptive position adjustments and can passively swing within a limited angle. Since the double-lumen flexible liquid guide tube 12 is designed as a medical spring tube, the double-lumen flexible liquid guide tube 12 bends synchronously when the floating jet core 13 swings, and ensures that the pre-wetting line and the main flushing line are always connected. After leaving the nasal cavity, the double-lumen flexible liquid guide tube 12 will quickly return to its original position, which will also drive the floating jet core 13 to return to its original position.

[0075] The guide layer 18 is connected to the outside of the floating jet core 13, and its main purpose is to form a passive guide; the conforming layer 19 is connected to the outside of the guide layer 18, and its main purpose is to form a flexible fit with the inner wall 26 of the nasal cavity; together they form a flexible fit and passive guide structure in the shallow part of the nostril entrance.
