Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a nasal washer. Background Art

[0002] In the operation process of relevant medical cleaning, nasal irrigation devices are being used more and more widely as a tool for cleaning the nasal cavity. Existing nasal irrigation devices are usually manual nasal irrigation devices and negative pressure nasal irrigation devices. In negative pressure nasal irrigation devices, a certain pressure, such as air pressure, is usually used to atomize physiological saline, which is sent into the nostrils to flow through the nasal vestibule (the part exposed outside the head), sinuses, and nasal passages around the nasopharynx, or discharged from one nostril, or discharged from the mouth. Through the above paths, with the help of the bactericidal effect of physiological saline itself and the impact force of the water flow, the pathogenic bacteria and dirt that have accumulated in the nasal cavity are discharged, so that the nasal cavity can restore its normal physiological environment, restore the self-detoxification function of the nasal cavity, and achieve the purpose of protecting the nasal cavity.

[0003] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art.

[0057] Embodiments of the first aspect

[0058] The embodiment of the present application provides a nasal rinser, which includes a cup holder, a sliding switch assembly mounted on the cup holder, and a plurality of drainage ports arranged on the cup holder and / or the sliding switch assembly.

[0059] In the above embodiment, an air inlet and an air outlet connected to the air inlet are provided on the cup holder. The sliding switch assembly includes a sliding switch, a sliding switch bracket supporting the sliding switch, and a valve plate installed on the sliding switch bracket. The sliding switch bracket can be linked with the sliding switch, and the valve plate can be linked with the sliding switch bracket. When the sliding switch is operated, the sliding switch drives the sliding switch bracket to move, and the sliding switch bracket drives the valve plate to move, thereby sealing or opening the above-mentioned multiple drain ports, thereby adjusting the spray rate of the nasal washer.

[0060] According to the above embodiment, the valve sheet can seal or open the multiple drain ports by operating the sliding switch assembly, thereby adjusting the spray rate of the nasal rinser, so that the spray rate of the nasal rinser can be adjusted to multiple gears according to the needs of the user without using electricity, thereby improving the convenience of using the nasal rinser. In addition, since the apertures of each drain port are fixed, the stability of the spray is guaranteed when the sliding switch assembly is adjusted to different gears.

[0061] Figure 1 Schematic diagram of the structure of the nasal washer 10 according to an embodiment of the present application; Figure 1 As shown, the nasal rinser 10 includes: a dust cover 11, a silicone nozzle 12, a waste liquid tank 13, a saline tank 14, a sealing gasket 15, and a cup holder 16. The above components are conventional components of existing nasal rinsers, and the nasal rinser 10 may also include other components, which can be specifically referred to the existing technology in the field, and will not be repeated here.

[0062] Figure 2 yes Figure 1 A schematic diagram of the internal structure of the nasal washer 10 shown; Figure 1 and Figure 2 As shown, the nasal washer 10 further includes: an air inlet A, an air outlet B, and a sliding switch assembly 20. The air inlet A and the air outlet B are both arranged on the cup holder 16, and the air inlet A is connected to the air outlet B; and the sliding switch assembly 20 is also installed on the cup holder 16.

[0063] like Figure 2As shown, the sliding switch assembly 20 includes: a sliding switch 21, a sliding switch bracket 22, and a valve plate 110. The sliding switch bracket 22 is located inside the cup holder 16, and is used to support the sliding switch 21 and to be linked with the sliding switch 21. The valve plate 110 is installed on the sliding switch bracket 22 and is linked with the sliding switch 21. In addition, a plurality of drain ports are provided on the cup holder 16 and / or the sliding switch assembly 20, and each drain port is connected with the air inlet A and the air outlet B. The specific setting position of the drain port will be described later.

[0064] Through the above structure, the valve plate 110 can move under the control of the slide switch 21 to seal or open the plurality of drain ports, thereby adjusting the spray rate of the nasal washer 10 .

[0065] The above-mentioned nasal rinse device 10 provided in the embodiment of the present application can flexibly adjust the spray rate of the nasal rinse device 10 by sealing or opening the multiple drain ports with the valve sheet 110 without using electricity, so that the spray rate of the nasal rinse device 10 can be adjusted to multiple gears according to the needs of the user, thereby improving the convenience of using the nasal rinse device 10. In addition, since the apertures of the multiple drain ports in the embodiment of the present application are fixed, the stability of the spray rate at each gear can be guaranteed.

[0066] In some embodiments, Figure 2 As shown, a track 19 is provided on the inner wall of the cup holder 16, and the sliding switch bracket 22 is installed inside the cup holder 16 through the track 19, and can slide on the track 19 in the direction in which the track 19 extends. In addition, an opening for installing the sliding switch 21 is provided on the cup holder 16, and a protrusion T is provided on one side of the sliding switch 21, and the protrusion T can be inserted into the opening and connected with the sliding switch bracket 22 inside the cup holder 16. When the sliding switch 21 moves up and down, the protrusion T can drive the sliding switch bracket 22 to move on the track 19. A valve plate 110 is also installed at one end of the sliding switch bracket 22 close to the air inlet A, and the valve plate 110 can move under the drive of the sliding switch bracket 22. Through the above structure, the user can operate the sliding switch 21 from the outside of the nasal rinser 10, and drive the sliding switch bracket 22 inside the nasal rinser 10 and the valve plate 110 installed on the sliding switch bracket 22 to move.

[0067] Thus, the valve plate 110 can seal or open the plurality of drain ports disposed on the cup seat 16 and / or the valve plate 110 , thereby adjusting the spray rate of the nasal rinser 10 .

[0068] In the above embodiment, the track 19 and the cup holder 16 are formed as one body, for example, the track 19 is arranged on the cup wall inside the cup holder 16 , thereby the sliding switch bracket 22 can be installed more stably.

[0069] Figure 1 and Figure 2 The working principle of the nasal wash device 10 shown is as follows: the air inlet A is connected to the air outlet B, and the air outlet B is connected to the silicone nozzle 12, and the air inlet A is connected to an external jet air flow source, such as a compressed atomizer, to deliver the air flow source to the nasal wash device 10. The air flow source flows through the air inlet A to the air outlet B, passes through the saline tank 14, and causes the physiological saline 17 stored in the saline tank 14 to be atomized and flow to the silicone nozzle 12, thereby forming a spray 18.

[0070] like Figure 2 As shown, in the embodiment of the present application, a plurality of leakage ports are provided below the air inlet A and / or on the valve plate 110, and the plurality of leakage ports can be used to adjust the airflow flowing into the air outlet B. Specifically, the plurality of leakage ports can control the amount of airflow entering the air outlet B. When most of the airflow entering the air inlet A is discharged from the plurality of leakage ports, the amount of airflow flowing into the air outlet B is reduced, and the air pressure is reduced, thereby reducing the spray rate of the nasal rinse device 10; on the contrary, when the plurality of leakage ports are sealed, the airflow entering the air inlet A flows into the air outlet B, and the air pressure is increased, thereby increasing the spray rate of the nasal rinse device 10. Therefore, by controlling the sliding switch 21 to control the movement of the valve plate 110, the plurality of leakage ports are sealed or opened, and the spray rate of the nasal rinse device 10 can be conveniently controlled. The specific arrangement of the plurality of leakage ports and the working process of the nasal rinse device 10 in the embodiment of the present application will be described later.

[0071] Figure 3 Schematic diagram of the sliding switch assembly 20 of the nasal washer 10 of the embodiment of the present application; Figure 3 As shown, at least two ribs 24 are provided on the cup holder 16 , at least one claw 23 is provided on the sliding switch bracket 22 , and the rib 24 is opposite to the claw 23 , and the rib 24 and the cup holder 16 are formed as one body.

[0072] like Figure 3 As shown, a groove G for installing and sliding the slide switch 21 is formed on the outer wall of the cup holder 16 , and an opening H is formed in the middle of the groove G. The slide switch 21 is installed on the cup holder 16 through the opening H and can slide in the groove G.

[0073] In the above embodiment, the rib 24 is formed as one body with the cup holder 16, and the material of the claw 23 is an elastic material, such as plastic, etc. The claw 23 and the rib 24 are distributed on both sides of the groove G and the opening H. The rib 24 is formed as a rectangular parallelepiped with edges and angles and protrudes in a direction perpendicular to the outer arm of the cup holder 16. The claw 23 is formed as a triangular cross section and is arranged parallel to the extension direction of the outer arm of the cup holder 16, and has a protruding acute angle extending in a direction that can partially overlap with the rib 24.

[0074] Through the above structure, during the sliding of the sliding switch 21, the claw 23 will slide with the sliding switch 21 and abut against the edge of the rib 24. Since the claw 23 is elastic, the claw 23 can contact the rib 24 and cause deformation but still be able to continue sliding. When the claw 23 slides away from the rib 24, the claw 23 recovers its deformation and is fixed by the rib 24, thereby locking the position of the sliding switch 21.

[0075] Figure 3 The figure shows that the sliding switch bracket 22 has two claws 23 and four ribs 24, but the present application is not limited to this. The number of claws 23 and ribs 24 can be adjusted according to the capacity and size of the nasal washer 10. For example, only one claw 23 and two ribs 24 are provided on one side of the sliding switch 21, and the present application does not limit this.

[0076] Through the above structure, the nasal washer 10 can be adjusted to different gears. Figure 4 Schematic diagram of the gear position of the sliding switch assembly 20 of the nasal washer 10 of the embodiment of the present application; in the embodiment of the present application, three gear positions are set: OFF gear, MIN gear, and MAX gear, which correspond to the following respectively: Figure 4 The first position 0, the second position 1, and the third position 2 are shown in FIG. The user can switch the nasal rinser 10 between the above three gears by controlling the sliding switch 21. Moreover, when the sliding switch 21 is adjusted to the MIN gear and the MAX gear, the position of the sliding switch 21 can be locked due to the structure of the claw 23 and the rib 24, that is, the gear can be locked. At this time, the user does not need to operate the switch all the time, and the nasal rinser 10 can also be maintained at the gear required by the user, thereby improving the convenience of the nasal rinser 10.

[0077] like Figure 4 As shown, S1 indicates that the slide switch 21 is in the OFF position, S2 indicates that the slide switch 21 is in the MIN position, and S3 indicates that the slide switch 21 is in the MAX position.

[0078] In the embodiment of the present application, the working process of the nasal washer 10 will be described with the above three gears, but it should be noted that the above gear setting is only an example. In some embodiments, the number of gears can be adjusted according to the number of flow adjustment claws 23 and ribs 24, and the present application does not impose any restrictions on this.

[0079] Next, the specific arrangement of the multiple drain ports will be described.

[0080] Figure 5 Yes Figure 2 A schematic diagram of setting multiple drain ports is shown; Figure 5As shown, in some embodiments, the plurality of drain ports include: a first drain port 111, a second drain port 112, and a third drain port 113. The first drain port 111 is disposed on the cup holder 16 and is directly connected to the air inlet A. For example, the first drain port 111 is formed by a first cylindrical portion 114 extending downward from the lower surface of the top plate of the cup holder 16. The upper opening of the first cylindrical portion 114 is connected to the air inlet A, and the lower opening of the first cylindrical portion 114 is connected to the interior of the cup holder 16. The second drain port 112 is disposed between the cup holder 16 and the valve plate 110 and is connected to the first drain port 111. For example, the second drain port 112 The valve plate 110 is formed by a second cylindrical portion 115 extending downward from the lower surface of the top plate of the cup holder 16 and a wall portion of the valve plate 110. The second cylindrical portion 115 is arranged around the first cylindrical portion 114, and the lower opening of the second cylindrical portion 115 is communicated with the interior of the cup holder 16. The third drain port 113 is arranged on the cup holder 16 and is communicated with the first drain port 111 and the second drain port 112. For example, the third drain port 113 is formed by a through hole arranged on the top plate of the cup holder 16. The through hole is formed at Figure 5 The illustrated left-right direction is located between the first cylindrical portion 114 and the second cylindrical portion 115 .

[0081] In the above embodiment, if Figure 5 As shown, the valve plate 110 has a mounting portion 116, a protruding portion 117 and an extending portion 118. Figure 5 As shown, the mounting portion 116 is formed into a cylindrical shape, and has a groove in the middle thereof that matches the protruding T-shape of the sliding switch bracket 22 , so that the valve plate 110 can be mounted on the sliding switch bracket 22 by interference fit. A protrusion 117 is provided at the top of the mounting portion 116. The cross-section of the protrusion 117 is semicircular, and the portion where the protrusion 117 is connected to the mounting portion 116 is formed in a stepped shape. Specifically, the outer circumference of the cross-section of the mounting portion 116 can be slightly larger than or slightly smaller than the outer circumference of the cross-section of the first cylindrical portion 114. The circumference of the cross-section at the connection between the protrusion 117 and the mounting portion 116 is slightly smaller than the outer circumference of the cross-section of the first cylindrical portion 114. In addition, an inwardly inclined surface is formed at the edge of the opening of the first cylindrical portion 114 facing the valve plate 110, so that the recess formed at the opening of the first cylindrical portion 114 can accommodate the protrusion 117 of the valve plate 110. When the first cylindrical portion 114 abuts against the protrusion 117, the protrusion 117 is completely engaged in the first cylindrical portion 114, thereby enabling the first drain port 111 to be better sealed.

[0082] The valve plate 110 also has a disc-shaped extension portion 118, such as Figure 5As shown, the extension portion 118 has a flat plate portion extending parallel to the top plate of the cup holder 16, and a cylindrical structure extending from the outer edge of the flat plate portion in a direction parallel to the second cylindrical portion 115. The inner circumference of the cylindrical structure of the extension portion 118 is slightly larger than the outer circumference of the second cylindrical portion 115, thereby forming a gap between the valve plate 110 and the second cylindrical portion 115, namely the second leakage port 112; and a circle of grooves is also provided at a portion of the flat plate portion of the extension portion 118 close to the outer edge, and a protrusion is formed at the edge of the open end of the second cylindrical portion 115, and the protrusion matches the shape of the groove of the extension portion 118. Therefore, when the valve plate 110 abuts against the second cylindrical portion 115, the opening edge of the second cylindrical portion 115 can be engaged in the groove of the flat plate portion of the extension portion 118, thereby enabling the second leakage port 112 to be sealed.

[0083] Figure 6 Yes Figure 5 A bottom view of a plurality of drain ports is provided as shown; Figure 5 and Figure 6 As shown in FIG. 1 , the aperture of the third drain port 113 is smaller than that of the first drain port 111. The second drain port 112 is a gap formed by the wall of the valve plate 110 and the second cylindrical portion 115. When the sliding switch 21 controls the valve plate 110 to move so that the valve plate 110 abuts against the second cylindrical portion 115, the gap is closed, that is, the second drain port 112 is sealed. Figure 5 As shown, at this time, the first leakage port 111 and the third leakage port 113 are connected; when the sliding switch 21 controls the valve plate 110 to continue to move and abuts against the first cylindrical portion 114, the first leakage port 111 is sealed, and the second leakage port 112 and the third leakage port 113 are also sealed.

[0084] Through the structure of the valve plate 110, the first cylindrical portion 114, and the second cylindrical portion 115, the sealing performance of the valve plate 110 is improved, thereby avoiding air leakage caused by poor sealing and thus causing malfunction of the nasal washer 10.

[0085] Figure 7 Yes Figure 5 Schematic diagram of the workflow when multiple drain ports are set; Figure 7 The arrows in the figure show the flow direction of the air flow source through the three drain ports. Figure 7 As shown, when the slide switch 21 is in the state of S1, i.e., the OFF position, the air inlet A is connected to the three drain ports, and the nasal rinser 10 is exhausted through the first drain port 111, the second drain port 112, and the third drain port 113. At this time, since most of the air is exhausted from the three drain ports, only a small amount or almost no air flow source flows to the air outlet B. Therefore, the nasal rinser 10 is in an inoperative state and does not spray.

[0086] When the user controls the slide switch 21 to slide to the state S2, i.e., the MIN gear, the second drain port 112 is sealed, and the nasal rinser 10 exhausts air through the first drain port 111 and the third drain port 113. Since the aperture of the third drain port 113 is small, the airflow discharged through the third drain port is small, and most of the airflow source flows into the air outlet B. At this time, the nasal rinser 10 sprays at the first flow rate;

[0087] When the user controls the sliding switch 21 to slide to the S3 state, i.e., the MAX gear, the first drain port 111 is sealed. At this time, all three drain ports are sealed. Therefore, the nasal rinser 10 has no exhaust, and the air flow source entering the air inlet A all flows into the air outlet B, and the nasal rinser 10 sprays at the second flow rate.

[0088] In the above embodiment, the second flow rate is greater than the first flow rate.

[0089] In the above embodiment, since the valve plate 110 is made of elastic material, when the user controls the sliding switch 21 to switch gears, it will deform, thereby contacting the first cylindrical portion 114 and / or the second cylindrical portion 115 inside the cup holder 16, thereby sealing or opening multiple leakage ports.

[0090] Through the above structure, the spray rate of the nasal rinser 10 can be adjusted without using electricity to change the gas flow rate. In addition, since the sliding switch assembly 20 can lock the gear position of the nasal rinser 10, the user does not need to press the switch all the time during use, which reduces the burden on the user and improves the convenience of use of the nasal rinser 10.

[0091] Figure 8 is another schematic diagram of the structure of the nasal washer 10 according to an embodiment of the present application. Fig. 9 yes Figure 8 A schematic diagram of the internal structure of the nasal washer 10 shown; Figure 8 and Fig. 9 As shown, the embodiment of the present application also provides another implementation scheme for setting multiple drain ports. Some implementation schemes are the same as the above contents and will not be repeated here. Only the different parts will be described.

[0092] like Figure 8 and Fig. 9 As shown, the nasal washer 10 provided in the embodiment of the present application has a valve sheet 120 .

[0093] Fig.10 Yes Fig. 9 A schematic diagram of setting multiple drain ports is shown in FIG. Fig. 9 and Fig.10 As shown, a spring 123 is further provided at the connection between the valve plate 120 and the sliding switch bracket 22 .

[0094] Furthermore, in the above embodiment, the first leakage port 121 is arranged on the cup holder 16 and is directly connected to the air inlet A. For example, the first leakage port 121 is composed of a third cylindrical portion 124 extending downward from the lower surface of the top plate of the cup holder 16. The upper opening of the first leakage port 121 is connected to the air inlet A, and the lower opening of the first leakage port 121 is connected to the interior of the cup holder; the second leakage port 122 is arranged on the valve plate 120 and is connected to the first leakage port 121, and the aperture of the second leakage port 122 is smaller than that of the first leakage port 121.

[0095] In the above embodiment, if Fig.10 As shown, the valve plate 120 has a first mounting portion 125, a second mounting portion 126 and a deformation portion 127. The first mounting portion 125 and the second mounting portion 126 are both formed in a cylindrical shape. From a vertical section, the length of the first mounting portion 125 is greater than that of the second mounting portion 126. From a cross section, the inner circumference of the first mounting portion 125 is slightly greater than the outer circumference of the second mounting portion 126. Therefore, a gap is formed between the first mounting portion 125 and the second mounting portion 126 to accommodate the spring 123. Fig.10 As shown, the lower end of the spring 123 is mounted on the protrusion of the sliding switch bracket 22, and the upper end of the spring 123 is engaged in the gap formed between the first mounting portion 125 and the second mounting portion 126. Through this structure, the valve plate 120 is mounted on the sliding switch bracket 22.

[0096] A deformation portion 127 is provided at the top of the first mounting portion 125 and the second mounting portion 126 . The deformation portion 127 is formed into a flat plate when the nasal washer 10 is not in operation, and a second drain port 122 is provided in the middle of the deformation portion 127 .

[0097] In the above embodiment, the outer circumference of the cross section of the first mounting portion 125 is slightly larger than the outer circumference of the cross section of the third cylindrical portion 124. Therefore, when the user controls the deformation portion 127 of the valve plate 120 to abut against the third cylindrical portion 124 through the sliding switch 21, the first drain port 121 can be closed. When the user further pushes the sliding switch 21, the upper portion of the valve plate 120 remains stationary due to the abutment with the third cylindrical portion 124. At this time, the protrusion of the sliding switch bracket 22 moves further upward, and when the protrusion abuts against the second mounting portion 126, the second drain port 122 is sealed.

[0098] In addition, since the valve plate 120 is made of elastic material, when the deformation portion 127 abuts against the third cylindrical portion 124, it will deform to form a groove, so that the opening outer edge of the third cylindrical portion 124 is engaged with the deformation portion 127, thereby completely sealing the first leakage port 121 and the second leakage port 122.

[0099] Through the above structure, when the user operates the sliding switch 21 to make the valve plate 120 abut against the third cylindrical portion 124, the first drain port 121 is sealed, and the first drain port 121 and the second drain port 122 are still connected; when the user operates the sliding switch 21 to continue sliding, the spring at the installation position of the sliding switch bracket 22 and the valve plate 120 is compressed, and the sliding switch bracket 22 further abuts against the second installation portion 126 inside the valve plate 120, so that the second drain port 122 is sealed, and the first drain port 121 is also sealed. In this way, the adjustment of the spray rate of different gears is achieved.

[0100] Fig.11 Yes Fig.10 The schematic diagram of the working process when multiple drain ports are provided is shown; the nasal washer 10 is also described with three gears of OFF, MIN, and MAX.

[0101] like Fig.11 As shown, when the slide switch 21 is in the state of S1, that is, the OFF position, the air inlet A is connected to both the drain ports. At this time, the gas entering the air inlet A of the nasal rinser 10 is discharged through the first drain port 121, and only a small amount of gas can flow into the air outlet B. Therefore, the nasal rinser 10 is in an inoperative state and does not spray.

[0102] When the user controls the slide switch 21 to slide to the state S2, i.e., the MIN gear, the first drain port 121 is sealed because the valve plate 120 abuts against the cup holder 16. At this time, the nasal rinser 10 is exhausted only through the second drain port 122. Therefore, most of the airflow entering the air inlet A flows into the air outlet B, and the nasal rinser 10 can spray at the first flow rate.

[0103] When the user controls the sliding switch 21 to slide to the S3 state, i.e., the MAX gear, the second drain port 122 is further sealed by the sliding switch bracket 22. At this time, the airflow entering the air inlet A all flows into the air outlet B, and the nasal rinser 10 has no exhaust. Therefore, the nasal rinser 10 can spray at the second flow rate.

[0104] In the above embodiment, the second flow rate is greater than the first flow rate.

[0105] In some embodiments, the flow rates at different gears can be adjusted by adjusting the apertures of multiple drain ports, which can be specifically set according to actual needs, and this application does not impose any restrictions on this.

[0106] With the nasal rinser 10 provided in the above-mentioned embodiment of the present application, the plurality of drain ports can be sealed or opened by operating the sliding switch assembly 20, thereby adjusting the spray rate of the nasal rinser 10, and the sliding switch assembly 20 is provided with claws 23 and ribs 24, which can lock the gear position, thereby enabling the spray rate of the nasal rinser to be adjusted according to the needs of the user without using electricity, and there is no need to keep pressing the switch during use, thereby improving the convenience of using the nasal rinser.

[0107] Furthermore, since the apertures of the plurality of drain ports in the embodiment of the present application are fixed, the stability of the spray rate at each gear position can be ensured.

[0108] In addition, the structure for adjusting the spray rate provided in the embodiment of the present application is simpler, easier to install, and more adaptable to different nasal washers.

[0109] The embodiments of the present application are described above in conjunction with specific implementation methods, but it should be clear to those skilled in the art that these descriptions are exemplary and are not intended to limit the scope of protection of the embodiments of the present application. Those skilled in the art can make various modifications and variations to the embodiments of the present application based on the spirit and principles of the embodiments of the present application, and these modifications and variations are also within the scope of the embodiments of the present application.
