Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a nasal washing and suction device. Background Art

[0002] At present, the electric nasal irrigators designed based on the Venturi principle on the market mainly use the pressure difference generated when water flows through the variable diameter pipe to spray the irrigating liquid into the nasal cavity at a specific pressure and flow rate to clean the inside of the nasal cavity. This working method can remove dirt, mucus and some allergens in the nasal cavity to a certain extent, and has a certain effect on relieving discomfort caused by excessive nasal secretions or nasal inflammation.

[0003] This type of electric nasal rinser can only achieve the function of nasal washing, that is, flushing the nasal cavity with water to flush foreign objects in the nasal cavity to the outside of the nasal cavity. However, in actual use, the simple nasal washing function cannot effectively deal with the situation where thick mucus or secretions in the nasal cavity adhere to the deep nasal cavity and are difficult to discharge. Many users still feel that there is residual mucus in the nasal cavity after using this type of nasal rinser, resulting in the nasal congestion feeling not being completely relieved.

[0004] Due to the lack of nasal suction function, users need to blow their noses to expel the flushing liquid and foreign objects in the nasal cavity during the nasal washing process. However, this method has many disadvantages. On the one hand, it is difficult to control the strength of blowing the nose. Excessive force may cause excessive pressure in the nasal cavity and cause ear diseases such as otitis media; on the other hand, for some children, the elderly or the weak, it may be difficult to blow their noses by themselves, and they cannot completely expel the liquid and foreign objects in the nasal cavity, which affects the effect of nasal washing and brings great inconvenience to users.

[0031] like Figures 1 to 5 As shown, it is an integrated nasal washing and suction device according to an embodiment of the present invention.

[0032] See also Figure 1-Figure 5 A nasal washing and suctioning device according to an embodiment of the present invention comprises a body 10, a nasal washing head 20, a nasal suction head 30, an air pump assembly 40 and a pipeline switching assembly 50. The body 10 is provided with a first mounting portion 14, a second mounting portion 15 and an adjustment hole 13. The nasal washing head 20 and the nasal suction head 30 are respectively detachably mounted on the first mounting portion 14 and the second mounting portion 15. The air pump assembly 40 is arranged in the body 10. The pipeline switching assembly 50 comprises an adjustment base 51, an adjustment top plate 52, a switching member 53 and a switching switch 54. The adjustment base 51 is arranged in the body 10. The middle part of the adjustment base 51 is provided with a first The air inlet 511 and the first air outlet 512 are respectively connected to the suction nozzle and the exhaust nozzle of the air pump assembly 40. The adjusting top plate 52 is provided with a second air inlet 521, a third air inlet 522, a second air outlet 523 and a third air outlet 524. The second air outlet 523 is connected to the nose washing head 20, and the third air inlet 522 is connected to the nose suction head 30. The middle part of the switching member 53 is provided with a first connecting groove 531 and a second connecting groove 532. The first air inlet 511 is connected to the first connecting groove 531, and the first air outlet 512 is connected to the second connecting groove 532.

[0033] The switching member 53 is slidably disposed between the adjustment base 51 and the adjustment top plate 52, and is used to switch the connection / isolation state of the second air outlet 523 and the third air outlet 524 with the first connecting groove 531, and the connection / isolation state of the second air inlet 521 and the third air inlet 522 with the second connecting groove 532. The switching switch 54 is disposed on the switching member 53 and extends into the adjustment hole 13.

[0034] In this embodiment, the body 10, the nose washing head 20 and the nose suction head 30 are arranged in a Y shape as a whole.

[0035] In this embodiment, the first air inlet 511 and the second air inlet 521 are disposed in the middle of the adjustment base 51 .

[0036] In this embodiment, when the nasal washing function needs to be realized, the switching member 53 is driven to slide to the left side of the adjustment base 51 by switching the switch 54, so that the second air outlet 523 is connected with the first connecting groove 531, and the second air inlet 521 is connected with the second connecting groove 532, and at the same time, the third air outlet 524 is isolated from the first connecting groove 531, and the third air inlet 522 is isolated from the second connecting groove 532. The air pump assembly 40 works, and the gas discharged from the air pump assembly 40 passes through the first air inlet 511, the first connecting groove, and the second air outlet 523, and finally enters the nasal washing head 20, thereby realizing the nasal washing function. At the same time, the gas in the fuselage 10 passes through the second air inlet 521, the second connecting groove 532, and the first air outlet 512, and finally enters the air pump assembly 40. When the nasal suction function is required, the switching member 53 is driven to slide to the right side of the adjustment base 51 by switching the switch 54, so that the third air outlet 524 is connected to the first connecting groove 531, and the third air inlet 522 is connected to the second connecting groove 532. At the same time, the second air outlet 523 is isolated from the first connecting groove 531, and the second air inlet 521 is isolated from the second connecting groove 532. The air pump assembly 40 works to inhale external air from the nasal suction head 30, which flows through the third air inlet 522, the second connecting groove 532, and the first air outlet 512, and finally enters the air pump assembly 40. The nasal suction cavity forms a negative pressure to realize the nasal suction function. At the same time, the gas discharged from the air pump assembly 40 passes through the first air inlet 511, the first connecting groove, and the third air outlet 524, and is finally discharged into the fuselage 10.

[0037] The integrated nasal washing and suction device of this embodiment is provided with a first mounting portion 14 and a second mounting portion 15 on the body 10, and the nasal washing head 20 and the nasal suction head 30 are respectively installed on the first mounting portion 14 and the second mounting portion 15, and a pipeline switching component 50 is provided in the body 10 for switching the gas pipeline, thereby realizing the switching function of nasal washing and nasal suction without replacing the joint, and the lateral movement of the switching member 53 is utilized to realize independent control of the dual gas circuits, thereby simplifying the overall layout.

[0038] See also Figure 4 and Figure 5 As shown, exemplarily, in some embodiments, a first positioning column 513 and a second positioning column 514 are respectively provided at both ends of the adjustment base 51, and a first positioning groove 533 adapted to the first positioning column 513 and a second positioning groove 534 adapted to the second positioning column 514 are respectively provided at both ends of the switching member 53.

[0039] When the switch 54 drives the switching member 53 to slide to the left side of the adjustment base 51, the switching member 53 slides to the first positioning column 513, and the first positioning column 513 is located in the first positioning groove 533. When the switch 54 drives the switching member 53 to slide to the right side of the adjustment base 51, the switching member 53 slides to the second positioning column 514, and the second positioning column 514 is located in the second positioning groove 534.

[0040] In this embodiment, by adapting the first positioning column 513, the second positioning column 514 and the first positioning groove 533, the second positioning groove 534, the position of the switching member 53 can be accurately defined. When the switching member 53 slides to different positioning columns, the corresponding gas paths are accurately connected or staggered, thereby ensuring the accuracy and reliability of gas path switching and avoiding gas path confusion.

[0041] Furthermore, the adjusting base 51 is also provided with a first positioning block 515, a second positioning block 516, a third positioning block 517 and a fourth positioning block 518. The first positioning block 515 and the second positioning block 516 are respectively located on both sides of the first positioning column 513, and the third positioning block 517 and the fourth positioning block 518 are respectively located on both sides of the second positioning column 514. The switching member 53 is also provided with a third positioning groove 535, a fourth positioning groove 536, a fifth positioning groove 537 and a sixth positioning groove 538. The third positioning groove 535 and the fourth positioning groove 536 are respectively located on both sides of the first positioning groove 533, and the fifth positioning groove 537 and the sixth positioning groove 538 are respectively located on both sides of the second positioning groove 534. The first positioning block 515 is adapted to the third positioning groove 535, the second positioning block 516 is adapted to the fourth positioning groove 536, the third positioning block 517 is adapted to the fifth positioning groove 537, and the fourth positioning block 518 is adapted to the sixth positioning groove 538.

[0042] When the switch 54 drives the switching member 53 to slide to the left side of the adjustment base 51 , the first positioning column 513 is located in the first positioning groove 533 , the first positioning block 515 is located in the third positioning groove 535 , and the second positioning block 516 is located in the fourth positioning groove 536 .

[0043] When the switching switch 54 drives the switching member 53 to slide to the right side of the adjusting base 51 , the second positioning column 514 is located in the second positioning groove 534 , the third positioning block 517 is located in the fifth positioning groove 537 , and the fourth positioning block 518 is located in the sixth positioning groove 538 .

[0044] In this embodiment, primary positioning is achieved by the cooperation of the positioning columns (first / second) and the main positioning grooves (first / second), and the positioning plates on both sides and the auxiliary positioning grooves (third to sixth) form secondary positioning. Double locking ensures that the switching member 53 is accurately positioned when sliding left and right.

[0045] Furthermore, the side of the first positioning column 513 away from the first positioning groove 533 is connected to the adjustment base 51 through the fifth positioning plate 519, and the side of the first positioning groove 533 close to the first positioning column 513 is provided with a first arc guide groove 5331, the inner diameter of the first arc guide groove 5331 is smaller than the outer diameter of the first positioning column 513, and the inner diameter of the first arc guide groove 5331 is greater than the width of the fifth positioning plate 519, and the side of the second positioning column 514 away from the second positioning groove 534 is connected to the adjustment base 51 through the sixth positioning plate 501, and the side of the second positioning groove 534 close to the second positioning column 514 is provided with a second arc guide groove 5341, the inner diameter of the second arc guide groove 5341 is smaller than the outer diameter of the second positioning column 514, and the inner diameter of the second arc guide groove 5341 is greater than the width of the sixth positioning plate 501.

[0046] When the switching member 53 slides, the positioning column (such as the first positioning column 513) will first contact the arc guide groove (such as the first arc guide groove 5331). Since the inner diameter of the arc guide groove is smaller than the outer diameter of the positioning column, the positioning column will be forced to slide within the trajectory of the arc groove, forming a "soft guide" to gradually correct the moving path and avoid directly hitting the edge of the main positioning groove. Moreover, the alignment accuracy can be reduced. Even if there is a slight offset in the initial position of the switching member 53, the arc profile of the arc groove can automatically adjust the entry angle of the positioning column through sliding friction to ensure that it finally slides accurately into the main positioning groove (such as the first positioning groove 533). In addition, the inner diameter of the arc guide groove is smaller than the outer diameter of the positioning column, forming a physical barrier. Even if the switching member 53 is subjected to vibration or unexpected external force, the positioning column cannot directly detach from the guide groove. It must slide in the opposite direction along the preset arc path to exit, preventing the gas path from being accidentally disconnected. During the switching process, the positioning column always maintains contact with the arc guide groove to prevent the switching member 53 from detaching from the predetermined trajectory due to inertia or impact force.

[0047] See also Figure 1-Figure 3 As shown, exemplarily, in some embodiments, the fuselage 10 includes a front shell 11 and a rear shell 12 detachably connected to the front shell 11, a first mounting plate 111 and a second mounting plate 112 are arranged in the front shell 11, the second mounting plate 112 is spaced apart above the first mounting plate 111, a third mounting plate 121 and a fourth mounting plate 122 are arranged in the rear shell 12, the fourth mounting plate 122 is spaced apart above the third mounting plate 121, and an adjustment base 51 and an adjustment top plate 52 are installed in a cavity formed by the first mounting plate 111, the second mounting plate 112, the third mounting plate 121 and the fourth mounting plate 122.

[0048] In this embodiment, the front shell 11 and the rear shell 12 are snap-connected and are easy to disassemble.

[0049] In this embodiment, the first mounting portion 14 includes a first sub-mounting portion and a second sub-mounting portion, and the first sub-mounting portion and the second sub-mounting portion are respectively arranged on the front shell 11 and the rear shell 12. Similarly, the second mounting portion 15 includes a third sub-mounting portion and a fourth sub-mounting portion, and the third sub-mounting portion and the fourth sub-mounting portion are respectively arranged on the front shell 11 and the rear shell 12.

[0050] Furthermore, a control button 113 is provided on the front shell 11, a circuit board 60 electrically connected to the control button 113 is provided in the front shell 11, a power supply 70 installation cavity is formed in the rear shell 12, a power supply 70 is installed in the power supply 70 installation cavity, the power supply 70 is electrically connected to the circuit board 60 and the air pump assembly 40 respectively, and the body 10 also includes a power supply cover 123 detachably connected to the rear shell 12, and the power supply 70 is configured to make it more convenient to use.

[0051] See also Figure 1-Figure 3 As shown, exemplarily, in some embodiments, the nasal wash head 20 includes a nasal wash body 21 and a nozzle 22. The nasal wash body 21 is installed in the first installation part 14. A sleeve 23 extends from the bottom of the nasal wash body 21 toward the direction of the nozzle 22. The sleeve 23 is connected to the second air outlet 523. A first storage cavity 24 is formed between the nasal wash body 21 and the sleeve 23. The first storage cavity 24 is connected to the sleeve 23. The nozzle 22 is installed on the top of the nasal wash body 21, and the nozzle 22 is provided with a spray port 221, which is connected to the first storage cavity 24.

[0052] In this embodiment, the first storage chamber 24 stores nasal wash liquid.

[0053] When the nasal wash function is required, the switching member 53 is driven to slide to the left side of the adjustment base 51 by switching the switch 54, and the air pump assembly 40, the first air outlet 512, the first connecting groove 531, the second air outlet 523, the sleeve 23 and the spray port 221 are connected in sequence to form a nasal wash channel. The air pump assembly 40 works, and the air enters the nasal wash channel and is finally discharged from the nozzle 22. During the air discharge process, the internal pressure of the sleeve 23 decreases, forcing the nasal wash liquid to be sucked into the spray port 221, and the nasal wash liquid is mixed with the air and discharged in a mist form, thereby achieving the nasal wash function.

[0054] In this embodiment, the nose washing head 20 has a compact structure and layout, so that the connections between the various components are tight and orderly, and the limited space is effectively utilized, which is suitable for use in miniaturized nose washing equipment. In addition, the nose washing body 21, the sleeve 23, the first storage chamber 24 and the nozzle 22 are integrated together to form a relatively independent nose washing module. This is not only convenient for production and assembly, but also convenient for overall maintenance and replacement of the nose washing part, thereby improving the maintainability of the equipment.
