Abstract
Description
Technical Field
[0001] This invention relates to nasal irrigation technology, and more specifically to a nasal irrigation device. Background Technology
[0002] Nasal irrigation devices play an important role in clinical treatment and daily home care. As a key step in removing nasal secretions, allergens, and germs, the rationality of the design of the irrigation head, the ease of operation, and the wide range of applicable populations have a decisive impact on the treatment effect, patient comfort, and nursing safety. In particular, in the core aspect of personalized irrigation for patients of different ages, existing nasal irrigation devices are gradually revealing their limitations in meeting the needs of different physiological structures, such as the adaptation of the wide nasal passages of adults to the narrow nasal passages of young children.
[0003] Because young children have narrow nasal passages and delicate mucous membranes, specialized children's nasal irrigation heads are usually designed to be small in size and have a slow flow rate. Adults, on the other hand, have larger nasal spaces and require larger irrigation heads with stronger water flow to achieve effective cleaning depth. However, current technologies often separate adult-specific and child-specific devices, lacking a universal solution that can be flexibly adapted or quickly switched. This forces medical institutions or home users to purchase two or more sets of equipment, which not only wastes resources and increases the economic costs for users and the space costs for equipment storage, but also poses a safety risk in emergency situations where alternating use is necessary, such as when both adults and children in the family suddenly develop rhinitis, as it is easy to use the wrong device, resulting in poor irrigation effect. There is also the risk of adults using children's nozzles, causing weak irrigation, or children using adult nozzles, causing nasal damage.
[0004] Therefore, the applicant proposes a nasal irrigation device to solve the above-mentioned problems. Summary of the Invention
[0005] The purpose of this invention is to provide a nasal irrigation device to solve the problem that existing nasal irrigation devices separate adult and pediatric devices, which lack versatility. This forces medical institutions or home users to purchase multiple sets of devices, which not only increases economic and space costs, but also easily leads to ineffective irrigation or damage to the nasal mucosa due to misuse of different sizes of irrigation heads.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a nasal irrigation device, comprising a housing mechanism, the housing mechanism including a mounting box, a power pump fixedly connected to both sides of the bottom of the inner cavity of the mounting box, a connecting pipe fixedly connected to one end of the power pump, and one end of the connecting pipe extending through the side wall of the mounting box to one side of the mounting box, a folding pipe fixedly connected to the other end of the connecting pipe, and a plug pipe fixedly connected to one end of the folding pipe, a partition provided in the middle of the inner cavity of the mounting box, and an adaptation slot provided on the top of the partition;
[0007] The upper part of the inner cavity of the installation box is provided with a docking mechanism. The docking mechanism includes a horizontal plate. Both sides of the top of the horizontal plate are provided with movable through grooves. Two mounting seats are respectively provided on both sides of the inner cavity of the movable through groove. The two sides of the mounting seats are slidably connected to the inner wall of the adjacent movable through groove. Two of the mounting seats are provided with adult rinsing tubes, and the other two mounting seats are provided with child rinsing tubes. The bottom of the adult rinsing tube passes through the inner cavity of the adapter through groove and is inserted into the top of the corresponding insertion tube.
[0008] The inner walls on both sides of the mounting box are provided with adjustment grooves, and the bottom of the inner cavity of the adjustment groove is provided with vertical grooves on both sides. Movable blocks are fixedly connected to both sides of the horizontal plate, and the outer surface of the movable blocks is slidably connected to the inner cavity of the corresponding adjustment groove and the two vertical grooves.
[0009] Furthermore, the upper surface of the mounting box is connected to cover plates on both sides by hinges.
[0010] Furthermore, folded shielding cloths are fixedly connected to both sides of the horizontal plate, and one side of the folded shielding cloths is fixedly connected to the inner wall of the corresponding mounting box.
[0011] Furthermore, handles are fixedly connected to both sides of the top of the horizontal plate, and the outer surfaces of the adult rinsing tube and the child rinsing tube are respectively fixedly connected to the inner walls of the corresponding mounting bases.
[0012] Furthermore, displacement blocks are fixedly connected to both sides of the mounting base, and displacement grooves are respectively opened on the inner walls of both sides of the movable through groove. One end of the displacement block is slidably connected to the inner cavity of the corresponding displacement groove.
[0013] Furthermore, a spacing adjustment mechanism is provided on one side of the inner cavity of the mounting box. The spacing adjustment mechanism includes a bidirectional lead screw. Both sides of the outer ring of the bidirectional lead screw are fitted with threaded sleeves. A support rod is fixedly connected to one side of the threaded sleeve. One side of the support rod is fixedly connected to one side of the corresponding insertion pipe.
[0014] Furthermore, each end of the bidirectional lead screw is fixedly connected to a handle by passing through the side wall of the corresponding mounting box via a bushing.
[0015] Furthermore, a sliding rod is provided between the two support rods, and the two ends of the sliding rod pass through the side wall of the corresponding support rod and are fixedly connected to the inner wall of the corresponding mounting box.
[0016] Furthermore, the bottom of the child rinsing tube is adapted to the top of the insertion tube.
[0017] Furthermore, a rubber gasket is fitted onto the upper part of the outer ring of the insertion tube.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] This solution utilizes adult and child nasal irrigation tubes, along with horizontal plates, movable blocks, adjustment slots, and vertical slots, to enable rapid switching between different nasal irrigation tube specifications. This design allows a single device to meet both the high-flow nasal irrigation needs of adults and the gentle nasal irrigation requirements of young children, eliminating the need for users to purchase two separate sets of equipment. This effectively reduces procurement and storage costs and avoids the risk of nasal cavity damage or ineffective cleaning due to misuse of the nozzle. Furthermore, the spacing adjustment mechanism, through the synergistic action of a two-way lead screw, threaded sleeve, support rod, and slide rod, can flexibly adjust the position of the insertion tube according to the user's nostril spacing, improving wearing comfort. Rubber gaskets ensure airtightness and watertightness at the connection points, preventing liquid leakage. The folded protective cloth provides dust protection when not in use, comprehensively enhancing the practicality and safety of the device.
[0020] With its adjustable spacing mechanism, the operator can rotate the handle to drive the bidirectional lead screw, causing the two threaded sleeves to move synchronously towards or away from each other. This, in turn, drives the insertion tube and the adult or child irrigation tube connected above to change their spacing via the support rod. The beneficial effect of this design is that it can flexibly and accurately adjust the distance between the output ends of the two irrigation tubes according to the differences in the width of the nose bridge and the distance between the nostrils of users of different ages. This ensures that the irrigation tube fits tightly against the user's nostrils, improving wearing comfort and sealing, and avoiding leakage of irrigation fluid or discomfort caused by mismatched spacing. At the same time, the guiding effect of the slide rod ensures the stability and accuracy of the adjustment process, making the device suitable for a wider range of people. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0032] As attached Figure 1 To be continued Figure 7 As shown:
[0033] Example 1:
[0034] The present invention provides a nasal irrigation device, including a housing mechanism 1, the housing mechanism 1 including a mounting box 101, a power pump 104 is fixedly connected to both sides of the bottom of the inner cavity of the mounting box 101, a connecting pipe 105 is fixedly connected to one end of the power pump 104, and one end of the connecting pipe 105 extends through the side wall of the mounting box 101 to one side of the mounting box 101, and a folded pipe 106 is fixedly connected to the other end of the connecting pipe 105, and a plug pipe 107 is fixedly connected to one end of the folded pipe 106. A partition 109 is provided in the middle of the inner cavity of the mounting box 101, and an adapter groove 108 is provided on the top of the partition 109.
[0035] The upper part of the inner cavity of the mounting box 101 is provided with a docking mechanism 2. The docking mechanism 2 includes a horizontal plate 201. Both sides of the top of the horizontal plate 201 are provided with movable through grooves 205. Two mounting seats 206 are respectively provided on both sides of the inner cavity of the movable through groove 205. The two sides of the mounting seats 206 are slidably connected to the inner wall of the adjacent movable through groove 205. Adult flushing tubes 208 are provided in the inner cavity of two mounting seats 206, and child flushing tubes 209 are provided in the inner cavity of the other two mounting seats 206. The bottom of the adult flushing tube 208 passes through the inner cavity of the adapter through groove 108 and is inserted into the top of the corresponding insertion tube 107.
[0036] The inner walls of the mounting box 101 are respectively provided with adjustment grooves 3, and the bottom of the inner cavity of the adjustment groove 3 is provided with vertical grooves 4 on both sides. The two sides of the horizontal plate 201 are respectively fixedly connected with movable blocks 5, and the outer surface of the movable blocks 5 is slidably connected to the inner cavity of the corresponding adjustment groove 3 and the two vertical grooves 4.
[0037] The upper surface of the mounting box 101 is rotatably connected to the cover plate 102 on both sides by hinges 103.
[0038] Working principle: When using this nasal irrigation device, if the user is an adult, the operator first connects the two connecting tubes 105 to the clean water tank and the waste water tank respectively. Then, the operator aligns the two adult irrigation tubes 208 on the horizontal plate 201 and inserts them into the user's nostrils. The operator then starts the power pump 104 at the bottom of the inner cavity of the mounting box 101. One of the power pumps 104, in conjunction with the connecting tube 105, draws water from the clean water tank. The water flows through the folded tube 106 and the insertion tube 107 and is delivered to the corresponding adult irrigation tube 208 for rinsing. At the same time, the other power pump 104, in conjunction with the folded tube 106 and the insertion tube 107 on the other side, generates negative pressure suction, causing the other... The adult flushing pipe 208 is in the drainage state, and the flushing wastewater is driven by the power pump 104 and discharged into the wastewater tank through the connecting pipe 105, realizing a one-in-one-out circulation flushing. Considering the differences in the width of the bridge of the nose and the distance between the nostrils of different adult users, the operator can rotate the handle 605 to drive the bidirectional screw 601 to rotate, causing the threaded sleeves 602 on both sides of the outer ring of the bidirectional screw 601 to move away from or towards each other. During the displacement, the threaded sleeves 602 push the corresponding insertion pipe 107 to move synchronously through the support rod 603. Since the two ends of the slide rod 604 are fixed to the inner wall of the mounting box 101 and pass through the support rod 603, the slide rod 604 effectively restricts the support. The displacement trajectory of rod 603 and insertion tube 107 ensures that the two adult flushing tubes 208 maintain a smooth linear movement when adjusting the spacing, thus accurately adapting to the nostril spacing of different users. When the user is a child, the operator holds the handle 203 at the top of the horizontal plate 201 with both hands and pulls it upward, causing the movable blocks 5 on both sides of the horizontal plate 201 to slide upward along the current vertical groove 4 until the movable blocks 5 enter the inner cavity of the adjustment groove 3. Then, the horizontal plate 201 is pushed horizontally, so that the movable blocks 5 move horizontally within the adjustment groove 3 to directly above another set of vertical grooves 4. Then, the horizontal plate 201 is pressed downward, so that the movable blocks 5 slide downward along the vertical groove 4 to reset. At this time, they are installed in the other two mounting seats 206. The child rinsing tube 209 descends, its bottom passing through the adapter groove 108 at the top of the partition 109 and tightly connecting with the top of the insertion tube 107 below. During this process, the rubber gasket 110 fitted on the upper part of the outer ring of the insertion tube 107 is deformed by pressure, filling the gap between the child rinsing tube 209 and the insertion tube 107, thus sealing and preventing leakage. At the same time, the folded cover cloth 202 connected to both sides of the horizontal plate 201 automatically unfolds or retracts with the rise and fall of the horizontal plate 201, sealing the space where the unused adult rinsing tube 208 is located, preventing dust from entering. After completing the mode switch, the power pump 104 can be started to gently rinse the child according to the above circulation principle.
[0039] This solution integrates an adult irrigation tube 208 and a child irrigation tube 209 within the same installation box 101. Utilizing the cooperation of the horizontal plate 201, movable block 5, adjusting groove 3, and vertical groove 4, it achieves rapid interchangeability between the two different specifications of irrigation tubes. This allows the same device to meet the needs of adults with wide nasal passages requiring high-flow, high-impact irrigation, while also adapting to the requirements of children with narrow nasal passages requiring small-volume, slow-flow irrigation. It eliminates the need for medical institutions or home users to purchase two separate sets of equipment, reducing economic procurement costs and equipment storage space costs. It also avoids nasal damage caused by mixing or misuse of equipment, such as children misusing adult nozzles. The device addresses the safety risks associated with adults misusing child-safe nozzles, leading to ineffective rinsing. Furthermore, the device's spacing adjustment mechanism 6, utilizing a two-way lead screw 601, a threaded sleeve 602, a support rod 603, and a slide rod 604, allows for flexible adjustment of the distance between the two insertion tubes 107 and the corresponding rinsing tubes based on the user's actual nostril spacing, enhancing wearing comfort and fit. The rubber pad 110 further ensures airtightness and watertightness when switching the child rinsing tube 209, preventing rinsing fluid leakage that could contaminate clothing or affect rinsing pressure. The folded cover 202 provides dust protection when a particular set of rinsing tubes is not in use.
[0040] Example 2:
[0041] This embodiment is basically the same as the previous embodiment, except that folded shielding cloths 202 are fixedly connected to both sides of the horizontal plate 201, and one side of the folded shielding cloths 202 is fixedly connected to the inner wall of the corresponding mounting box 101.
[0042] Handles 203 are fixedly connected to both sides of the top of the horizontal plate 201. The outer surfaces of the adult rinsing tube 208 and the child rinsing tube 209 are fixedly connected to the inner walls of the corresponding mounting bases 206.
[0043] Displacement blocks 204 are fixedly connected to both sides of the mounting base 206. Displacement grooves 207 are respectively opened on the inner walls of both sides of the movable through groove 205. One end of the displacement block 204 is slidably connected to the inner cavity of the corresponding displacement groove 207.
[0044] A spacing adjustment mechanism 6 is provided on one side of the inner cavity of the mounting box 101. The spacing adjustment mechanism 6 includes a bidirectional lead screw 601. Both sides of the outer ring of the bidirectional lead screw 601 are fitted with threaded sleeves 602. A support rod 603 is fixedly connected to one side of the threaded sleeve 602. One side of the support rod 603 is fixedly connected to one side of the corresponding insertion tube 107.
[0045] Working principle: The upper surface of the mounting box 101 is connected to cover plates 102 via hinges 103 on both sides. When the device is idle or being transported, the operator rotates the cover plates 102 around the hinges 103 to close them, covering the top opening of the mounting box 101. When in use, the cover plates 102 are opened. This prevents external dust and debris from entering the inner cavity of the mounting box 101 and contaminating the power pump 104, connecting pipe 105, and flushing pipes. It also protects internal precision components from accidental impact damage, keeps the equipment clean, and extends its service life. Folded shielding cloths 20 are fixedly connected to both sides of the horizontal plate 201. 2. Furthermore, the folded shielding cloth 202 is fixedly connected to the inner wall of the corresponding mounting box 101. When the operator pulls the horizontal plate 201 to switch between the adult rinsing tube 208 and the child rinsing tube 209, the folded shielding cloth 202 automatically unfolds or retracts with the movement of the horizontal plate 201, always filling the gap between the edge of the horizontal plate 201 and the inner wall of the mounting box 101. This effectively seals the internal space of the mounting box 101 during the movement of the horizontal plate 201, preventing unused rinsing tubes from being exposed to the outside and getting dusty. At the same time, it avoids water mist splashing into the non-working area of the equipment during rinsing operations, which could cause short circuits or mechanical corrosion.
[0046] Example 3:
[0047] This embodiment is basically the same as the previous embodiment, except that the two ends of the bidirectional lead screw 601 are respectively fixedly connected to a handle 605 by passing through the side wall of the corresponding mounting box 101 through the bushing.
[0048] A sliding rod 604 is provided between the two support rods 603. The two ends of the sliding rod 604 pass through the side wall of the corresponding support rod 603 and are fixedly connected to the inner wall of the corresponding mounting box 101.
[0049] The bottom of the child flushing tube 209 is adapted to the top of the insertion tube 107.
[0050] A rubber gasket 110 is fitted onto the upper part of the outer ring of the insertion tube 107.
[0051] Working principle: Displacement blocks 204 are fixedly connected to both sides of the mounting base 206, and displacement grooves 207 are respectively opened on the inner walls of both sides of the movable through groove 205. One end of the displacement block 204 is slidably connected to the inner cavity of the corresponding displacement groove 207. When the horizontal plate 201 is moved by force, it drives the mounting base 206 and the displacement block 204 on it to slide linearly along the trajectory of the displacement groove 207 in the movable through groove 205. This achieves precise guidance and limitation of the movement path of the mounting base 206 and the adult rinsing tube 208 or child rinsing tube 209 fixed on it, preventing them from shaking, jamming or rotating during movement, and ensuring that the rinsing tube can be accurately aligned with the insertion tube 107 below for smooth insertion. A spacing adjustment mechanism 6 is provided on one side of the cavity. This mechanism includes a bidirectional lead screw 601. Both sides of the outer ring of the bidirectional lead screw 601 are fitted with threaded sleeves 602. A support rod 603 is fixedly connected to one side of the threaded sleeve 602. One side of the support rod 603 is fixedly connected to one side of the corresponding insertion tube 107. When the operator rotates the bidirectional lead screw 601, it drives the threaded sleeves 602 on both sides to move synchronously towards or away from each other along the axis of the lead screw. In turn, the support rod 603 pushes the two insertion tubes 107 to change the distance between them. This allows for flexible and precise adjustment of the distance between the two flushing tube output ends according to the differences in the width of the nose bridge of users of different ages or individuals. This makes the device fit the user's nostril better, improving wearing comfort and flushing seal.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
