Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nasal irrigator for washing a nasal cavity by squirting a washing liquid stored in a container from a nozzle.

[0002]

2. Description of the Related Art Conventionally, various nasal washing machines have been proposed for washing out pathogens, house dust, pollen, and the like adhering to the nasal cavity and secretions accumulated in the nasal cavity. In such a nasal irrigator, a nozzle is attached to a flexible container in which the washing liquid is stored, and the flexible container is compressed by hand to reduce the volume of the flexible container, so that the washing liquid flows from the nozzle. Some erupt. For example, JP-A-9-225
No. 026, as described. In addition, the piston type pump device is attached to the container in which the cleaning liquid is stored, and the piston of the pump device is operated up and down so that the cleaning liquid is ejected from the nozzle connected to the container by the pipe by the recoil of the vertical movement of the piston. There are those that have been configured. For example, JP-A-9-75458 and JP-A-6-486.
No. 59, as described.

[0003]

However, as described above,
In a cleaning device configured to eject cleaning liquid by the recoil of the piston type up and down operation, a single operation of the piston can only eject a small amount of cleaning liquid.In order to perform cleaning sufficiently, the piston operation must be performed many times. It had to be repeated. Therefore, when performing cleaning, it is necessary to perform a cleaning operation such as adjusting a cleaning position by placing a nozzle on a nostril with one hand, and repeatedly performing up and down operations of a piston with the other hand. The operation of the nasal irrigator at the time was complicated, and it was not possible to concentrate on the cleaning operation. In a cleaning device configured to compress the flexible container by hand and eject the cleaning liquid, the amount and pressure of the ejection of the cleaning liquid suddenly change depending on the degree of compression and the compression speed of the flexible container. It is difficult to stably eject the cleaning liquid with the same amount and strength as described above, and considerable skill is required to perform cleaning comfortably and sufficiently. Furthermore, in order to eject a sufficient amount of cleaning liquid to be able to sufficiently clean, it is necessary to repeatedly perform the compression operation of the flexible container, and the operation is complicated. Further, in the above-mentioned nasal irrigator, since the operation unit for ejecting the washing liquid is provided near the container, the operation of ejecting the washing liquid and the washing operation with the nozzle must be performed at a separate place. Operation was complicated.

FIG. 8 is a side sectional view showing another embodiment of the on-off valve, and FIG. 9 is a side sectional view showing a nozzle.

First, the schematic structure of the nasal irrigator of the present invention will be described. As shown in FIGS. 1 and 2, the nasal irrigator 1
It comprises a container 2 for storing a cleaning liquid, a pump device 3 for accumulating pressure in the container 2, a nozzle 5 for ejecting the cleaning liquid stored in the container 2, and the like. The container 2 is formed, for example, in a substantially rectangular parallelepiped shape, and when the container 2 is installed in a wash space or the like when the nasal washing device 1 is used at home or the like,
It can be installed in a space-saving manner without creating unnecessary space in corners and the like. The container 2 is made of, for example, a transparent or translucent member, and one or more scales 2b are provided on the outer surface of the container 2. With the scale 2b, the amount of the cleaning liquid stored in the container 2 can be externally confirmed, and the maximum amount and the minimum amount of the cleaning liquid stored in the container 2 can be displayed.

A hose 8 extends from the container 2, and an opening / closing valve 7 is connected to a tip of the hose 8, and a nozzle 5 is connected to a tip side of the opening / closing valve 7. That is, the nozzle 5 is connected to the container 2 by a hose 8 which is a tubular member, and an opening / closing valve 7 is interposed between the nozzle 5 and the container 2, and the opening / closing valve 7 is arranged near the nozzle 5. ing. In addition, on-off valve 7
Is provided with an operation lever 6, and the on-off valve 7 can be opened and closed by operating the operation lever 6. The hose 8 has flexibility and is bendable. Further, the hose 8 can be formed in a spiral shape so that the hose 8 can be entangled or the space occupied by the hose 8 during storage can be reduced.

Next, the pump device 3 will be described. As shown in FIG. 2, the pump device 3 includes a lid 11, which is a main body, a cylinder 12, a piston 13, a handle 16, and the like, and the lid 11 is formed on an upper surface of the container 2. The pump device 3 is detachably attached to the container 2 by being screwed into the attachment hole 2a. A sealing member 20 such as an O-ring is interposed at a boundary between the lid 11 and the container 2. The pump mounting hole 2 a is sealed by screwing the lid 11. Make up. A substantially cylindrical cylinder 12 extends downward from the lid 11, and a piston 13 is inserted into the cylinder 12 so as to be vertically slidable.

The upper end of the piston 13 projects above the lid 11, and a handle 16 is formed at the upper end. A seal member 15 such as an O-ring is fitted on the lower end of the piston 13, and is disposed between an upper flange 13 a and a lower collar 13 b protruding from the outer periphery of the piston 13. A space below the piston 13 in the cylinder 12 is formed as a pressurizing chamber 14. The piston 13
A pressure hole 12a is opened on the lower surface of the device, and a one-way valve 18 for opening and closing the pressure hole 12a is attached by a cap 19.

The one-way valve 18 is formed of an elastic member having flexibility. For example, the one-way valve 18 has a valve portion 18a in contact with the pressure hole 12a and a leg portion for urging the valve portion 18a toward the pressure hole 12a. 19b. A hole 19a is opened in the bottom of the cap 19 holding the one-way valve 18.

In the pump device 3 configured as described above, when the piston 13 is slid downward with the handle 16, the inside of the pressurizing chamber 14 of the cylinder 12 is pressurized.
In this case, as shown in FIG. 3, the seal member 15 is pushed outward by the pressure in the pressurizing chamber 14 and pressed against the upper collar portion 13 a of the piston 13 and the inner peripheral surface of the cylinder 12. The inside of the pressurizing chamber 14 can be efficiently pressurized without the pressure in the pressurizing chamber 14 leaking to the outside. When the inside of the pressurizing chamber 14 is pressurized by the piston 13, the valve portion 18a of the one-way valve 18 is pushed downward against the urging force of the leg portion 18b, and separates from the pressurizing hole 12a. The pressure hole 12a opens. Thus, the air pressurized in the pressurizing chamber 14 flows into the container 2 through the pressurizing chamber 12a and the hole 19a of the cap 19, and the inside of the container 2 is pressurized.

Conversely, when the piston 13 is slid upward, the pressure in the pressurizing chamber 14 is reduced to a pressure lower than the pressure in the container 2, so that the valve portion 18a comes into contact with the pressurizing hole 12a. One-way valve 18 closes. In this case, as shown in FIG. 4, the inside of the pressurizing chamber 14 is in a decompressed state, and the seal member 15 is sucked inward and downward. A gap is generated, and the inside of the pressurizing chamber 14 communicates with the outside, and the inside of the pressurizing chamber 14 is filled with air.

As described above, air is filled into the pressurizing chamber 14 by sliding the piston 13 upward, and the inside of the container 2 is pressurized by sliding downward. By repeatedly performing the vertical sliding operation described above, it is possible to accumulate the pressure in the container 2. The container 2 is provided with a pressure regulating valve 9. When the pressure in the container 2 becomes a predetermined value or more, the pressure regulating valve 9 is provided.
Allows pressure to escape to the outside.

As described above, since the pump device 3 is capable of accumulating the pressure in the container 2 by manual operation, the pump device 3 can have a simple configuration and can be configured at a low cost. Further, the pump device 3 is configured as a pump device having a one-way valve 18 and capable of accumulating the pressure in the container 2 by operating the piston 13 up and down, so that the container 2 can be reliably operated with a simple operation. It is possible to accumulate pressure inside.

An engagement claw 17 is formed on the upper surface of the lid 11, and when the piston 13 is pushed down to the lowest position, the engagement projection 1 formed on the upper end of the piston 13 is formed.
3 a is configured so as to be able to engage with the engaging claw 17. With this configuration, the position of the piston 13 can be stably fixed after the operation of accumulating the pressure in the container 2 is completed, and the handle 16 is held,
The nasal irrigator 1 can be easily carried.

Further, since the pump device 3 is detachably attached to the container 2, maintenance and replacement of the pump device 3 and the like can be easily performed, and the pump device is provided separately from the container 2. The nasal irrigator 1 can be made smaller than in the case where it is used. Further, when attaching and detaching the pump device 3 screwed to the container 2 to and from the container 2, it is necessary to rotate the lid 11 with respect to the container 2, but as shown in FIG. A locking piece 22 is formed on the upper surface of the lid 11 so that the lid 11 can be rotated by putting a finger on the locking piece 22. Thereby, a force is easily applied to the lid 11, and the pump device 3 is easily attached to and detached from the container 2.

In the container 2, an in-container hose 8a is provided and connected to the hose 8 extending to the outside. The hose 8a in the container has its lower end positioned at or near the bottom surface of the container 2 so that substantially the entire amount of the cleaning liquid in the container 2 can be ejected from the nozzle 5 without waste. Further, a strainer 21 is attached to the lower end of the in-container hose 8a to remove foreign substances such as dust and dirt mixed in the cleaning liquid.

Next, the structure of the on-off valve 7 will be described. As shown in FIGS. 5 and 6, the casing 26 of the on-off valve 7 is formed in a substantially cylindrical shape, the hose 8 is connected to one end 26a, and the on-off valve 7 and the nozzle 5 are connected to the other end 26b. Are connected. A cylinder portion 27 is formed in the casing 26, and a piston 29 is fitted into the cylinder portion 27 so as to be vertically slidable.

An upper seal member 28a is externally fitted to the upper part of the piston 29, and a lower seal member 28b is externally fitted to the lower part. The upper seal member 28a separates the space inside the cylinder part 27 from the outside, and the lower seal member 28
The space in the cylinder 27 is divided into an upper space 27a and a lower space 27b by b. The piston 29 is urged upward by a spring 30, and a pressing surface 29a is formed on the upper end of the piston 29.

Above the piston 29, the operating lever 6
Are disposed, and a support pin 6b formed on the cam body 6a of the operation lever 6 is rotatably supported by a lever support portion 26c formed on the casing 29. A pressing surface 29 a of the piston 29 urged upward by the spring 30 is in contact with the cam 6 a of the operation lever 6.
When the lever portion 6C of the operation lever 6 is rotated downward, the piston 29 is pushed down against the urging force of the spring 30 by the cam body 6a abutting on the pressing surface 29a.

An introduction opening 26d is opened on the wall of the cylinder 27 on the hose 8 side, and an outlet opening 26e is opened on the wall of the cylinder 25 on the pipe 25 side.
When the operation lever 6 is not rotated downward, the hose 8 communicates with the upper space 27a in the cylinder 27 through the introduction opening 26d, and the pipe 25 communicates with the lower space 27b through the lead-out opening 26e. Has been
The inlet opening 26d and the outlet opening 26e are separated by a seal member 28b. That is, when the operation lever 6 is not operated to rotate downward, the on-off valve 7 is closed so that the cleaning liquid in the container 2 is not sprayed from the nozzle 5.

When the on-off valve 7 is closed, the operating lever 6 is pivoted downward and the piston 29 is moved by the cam 6a.
Is pressed down, the sealing member 28b moves down,
The lead-out opening 26e is located in the upper space 27a in the cylinder 27.
As a result, the hose 8 and the pipe 25 communicate with each other. That is, when the operation lever 6 is rotated downward, the on-off valve 7 is opened, and the cleaning liquid in the container 2 can be ejected from the nozzle 5.

As described above, when the operating lever 6 is rotated downward to slide the piston 29 downward, the sealing member 2
8b passes downward from the upper end of the outlet opening 26e, and the outlet opening 26e slides in the sliding direction of the piston 29 (the vertical direction in FIG. 7) as shown in FIG.
The opening area of the lead-out opening 26e which is formed in a long hole and communicates with the upper space 27a increases in proportion to the downward rotation amount of the operation lever 6. On the other hand, the introduction opening 2
6d is configured such that the entire opening area thereof communicates with the upper space 27a over the entire operable range of the operation lever 6 (that is, the sliding range of the piston 29).
The opening area of the introduction opening 26 d is formed smaller than the cross-sectional area of the hose 8.

Therefore, in the initial stage of the process in which the piston 29 slides downward, the area of communication between the outlet opening 26e and the upper space 27a is small, and the cleaning liquid sent out from the hose 8 into the upper space 27a at a constant pressure. Is the opening 2
Since the cleaning liquid is squeezed at 6e, the amount of the cleaning liquid ejected toward the nozzle 5 is small, and the pressure of the cleaning liquid is low. Thereafter, as the piston 29 slides downward, the area of communication between the outlet opening 26e and the upper space 27a gradually increases, the amount of the cleaning liquid jetted increases, and the cleaning liquid pressure increases.

That is, in accordance with the degree of sliding operation of the piston 29 by the operating lever 6, the opening area of the lead-out opening in the upper space 27a, which is the communication part between the lead-in opening 26d and the lead-out opening 26e, changes. It is composed.
The opening area of the lead-out opening 26e may be constant while the opening area of the introduction opening 26d with respect to the upper space 27a is changed according to the degree of sliding operation of the piston 29 by the operation lever 6. It is possible. Also,
If the sliding position of the piston 29 is kept constant, the ejection amount and ejection pressure of the cleaning liquid ejected toward the nozzle 5 will be kept constant.

As described above, the ejection amount and ejection pressure of the cleaning liquid ejected from the nozzle 5 are adjusted in accordance with the degree of the rotation operation of the operation lever 6. The relationship between the amount of rotation of the operation lever 6 and the amount and pressure of the cleaning liquid ejected from the nozzle 5 is determined by the introduction opening 26 d and the ejection opening 2.
It can be arbitrarily set according to the opening area and shape of 6e, the shape of the cam body 6a, and the like.

The on-off valve 7 can also be configured as follows. The casing 56 of the on-off valve 37 shown in FIG. 8 is formed in a substantially cylindrical shape, the hose 8 is connected to one end 56a, and the on-off valve 37 and the nozzle 5 are connected to the other end 56b.
Are connected to each other. A tube 57 is provided in the casing 56, and one end 57 a of the tube 57 is connected to the hose 8, and the other end 57 b is connected to the pipe 25. Communication. The tube 57 is made of a member having flexibility and elastic restoring force.

An operation lever 36 is provided above the casing 56.
The support pin 36b formed on the cam body 36a of the operation lever 3 is rotatably supported by a lever support portion 56c formed on the casing 56. Further, the spring member 3 is provided from the lever portion 36c of the operation lever 36.
6d is extended, and the tip of the spring member 36d contacts the outer peripheral surface of the casing 56 to urge the lever portion 36c upward. The spring member 36 is formed of a member having elasticity. When the spring member 36 is bent by a downward rotation operation of the lever portion 36c, it generates an urging force for urging the lever portion 36c upward.

The spring member 36 is formed integrally with other components of the operating lever 36 such as the cam body 36a and the lever 36c, for example, by a synthetic resin. As described above, by forming the spring member 36 integrally with the operation lever, the number of components is reduced, the cost is reduced, and the assembling operation of the operation lever 36 and the on-off valve 37 is facilitated. Can be.

The lever member 36 is moved by the spring member 36.
In the operation lever 36 in a state where c is urged upward,
The cam body 36a is in pressure contact with the tube 57, and the tube 57 is crushed by the cam body 36a and the support 56d of the casing 56. In this state, the hose 8 is connected to the cam body 36a of the tube 57.
The path 57c on the side is separated from the path 57d on the pipe 25 side from the cam body 36a. That is, when the lever portion 36c of the operation lever 36 is not operated to rotate downward, the on-off valve 37 is closed so that the cleaning liquid in the container 2 is not sprayed from the nozzle 5.

When the lever 36c is rotated downward from the closed state of the on-off valve 37, the contact surface of the cam body 36a with the tube 57 moves in a direction away from the tube 57, and the tube 57 is crushed. To a lesser degree,
The path 57c and the path 57d communicate with each other, and as a result, the hose 8 and the pipe 25 communicate with each other. That is, when the operation lever 36 is rotated downward, the on-off valve 37 is opened, and the cleaning liquid in the container 2 can be ejected from the nozzle 5.

In this case, the cam body 36a is
When the tube 6 is rotated downward, the shape of the contact surface with the tube 57 is adjusted so that the degree of crushing of the tube 57 gradually decreases and the cross-sectional area of the tube 57 in the crushed portion gradually increases. Is formed, and it is possible to adjust the ejection amount and ejection pressure of the cleaning liquid ejected from the nozzle 5 according to the degree of the rotation operation of the operation lever 36. In addition, if the rotational operation position of the operation lever 36 is kept constant, the ejection amount and ejection pressure of the cleaning liquid ejected from the nozzle 5 will be kept constant.
The relationship between the amount of rotation of the operation lever 36 and the amount and pressure of the jet of the cleaning liquid from the nozzle 5 can be arbitrarily set according to the size of the inner diameter of the tube 57, the shape of the cam 6a, and the like. is there.

In the opening / closing valve 37 configured as described above, the cleaning liquid delivered from the container 2 comes into contact with only the tube 57 while flowing from the hose 8 to the pipe 25. The other components and the operation lever 36 are not corroded or deteriorated by the cleaning liquid, so that the reliability of the nasal irrigator 1 can be improved, and maintenance such as replacement of parts is not required. Further, the operating lever 36 is integrally formed with a spring member 36d for biasing the lever portion 36c, so that the number of components can be reduced, and the cost can be reduced by integrally molding with a synthetic resin or the like. Can be planned.

Next, the configuration of the nozzle 5 will be described.
As shown in FIG. 9, the nozzle 5 includes an inner nozzle 5a formed of a cylindrical member having a closed end, and an outer nozzle 5 formed of a cylindrical member having a closed end and mounted on the inner nozzle 5a.
b, and the inner nozzle 5a and the outer nozzle 5b are screwed. A plurality of inner nozzle holes 31 are formed at the tip of the inner nozzle 5a, and the nozzle holes 3 are formed at the tip of the outer nozzle 5b.
2 are formed. The pipe 25 is connected to a base end of the inner nozzle 5a. The cleaning liquid delivered when the on-off valve 7 is opened passes through the inner nozzle hole 31 of the inner nozzle 5a and the nozzle 32 of the outer nozzle 5b and is ejected to the outside.

In the nozzle 5, the inner nozzle 5a
By rotating the outer nozzle 5b screwed with the inner nozzle 5a, the tip of the inner nozzle 5a and the outer nozzle 5b are rotated.
The size of the gap with the tip can be adjusted, and by adjusting the size of the gap, the state of ejection of the cleaning liquid from the nozzle 5 can be switched between DC and spray flow.
This makes it possible to switch the ejection state of the washing liquid according to the user's preference and the state in the nostrils, and it is possible to perform comfortable and sufficient washing.

An example of use of the nasal irrigator configured as described above will be described. First, with the pump device 3 detached from the container 2, a cleaning liquid is injected into the container 2 from the pump mounting hole 2a. After injecting the cleaning liquid, the pump device 3 is screwed into the pump mounting hole 2a and mounted on the container 2.
After that, the piston 13 of the pump device 3 is vertically slid to store the pressure in the container 2. As described above, when the pressure in the container 2 is accumulated, the cleaning liquid can be ejected from the nozzle 5.

The nozzle 32 of the nozzle 5 of the nasal washing device 1 in a state where the pressure in the container 2 is accumulated is located near or inserted into the nostrils to be cleaned, and the lever 6c of the operating lever 6 is moved. The opening / closing valve 7 is opened by rotating. Then, due to the accumulated pressure in the container 2, the cleaning liquid stored in the container 2 is sent to the nozzle 5 through the in-container hose 8 a, the hose 8, the on-off valve 7, and the pipe 25, and is ejected from the nozzle 32. You. Then, the inside of the nostrils is cleaned with the cleaning liquid spouted from the spout 32.

In this case, since a constant pressure is accumulated in the container 2, the cleaning liquid is stably ejected from the nozzle 5 at a constant pressure while the on-off valve 7 is open. There is no need to operate the pump device 3 during washing,
With a simple operation just by operating the operation lever 6, the cleaning can be performed while the cleaning liquid is stably ejected for a long time. As a result, it is possible to concentrate on the cleaning operation such as adjusting the position of the nozzle 5, and it is possible for anyone, whether a beginner or an expert, to perform comfortable and sufficient cleaning. In addition, since the amount and pressure of the flushing liquid can be easily adjusted by operating the operating lever 6, the amount and pressure of the flushing liquid can be arbitrarily set according to the user's preference and the condition in the nostrils. In addition, more comfortable and sufficient cleaning can be easily performed.

Further, since the opening / closing valve 7 for switching the jetting / stopping of the cleaning liquid from the nozzle 5 is arranged near the nozzle 5, the operation of jetting the cleaning liquid and the nozzle 5 while holding the opening / closing valve 7 with one hand is performed. Can be performed at the same time as the washing operation performed by contacting with the nostril, the washing operation can be simplified, and sufficient washing can be easily performed.

Further, in the present nasal washing device 1, the container 2, the pump device 3, the hose 8, the on-off valve 7, the pipe 25,
It is possible to entirely configure a portion of each component such as the nozzle 5 that contacts the cleaning liquid with a resin member. Thereby, even when using physiological saline or the like as the washing liquid, the components of the nasal irrigator 1 do not corrode or deteriorate, and can be used stably for a long period of time. Reliability can be improved.
