Spray nose washing device

Technical Field

The invention relates to a spray nasal irrigation device, in particular to a spray nasal irrigation device which can fully atomize spray liquid and completely guide the spray liquid into a nasal cavity so as to improve the overall spray irrigation effect.

Background

Western medicine believes that when the cilia oscillation frequency of the respiratory tract is reduced by the induction factors of cold catching, rain catching, excessive fatigue and the like of a human body, viruses, bacteria and fungi which originally exist in the respiratory tract and invade from the outside can be rapidly propagated to cause cold. Inflammation of the nasopharynx is the main manifestation. The major common cold causing agents are rhinoviruses.

In prevention, the nose is washed away every morning and evening to wash away virus and harmful substances accumulated in the nasal cavity, so that the virus and the harmful substances are prevented from propagating in large quantities and invading human bodies. And simultaneously creates conditions for the recovery of damaged nasal tissues. The two components act together to improve the resistance of human body.

In treatment, the cold virus firstly proliferates in the epithelial cells of the nasal cavity in a large amount and then invades the human body. However, the mucus secreted by the nasal mucosa, known as a rhinorrhea, is a large quantity of mucus which continuously discharges the virus. Therefore, the nasal discharge and a large amount of viruses in the nasal discharge can be washed out by continuously cleaning the nasal cavity, the viruses are prevented from entering the human body again, and the number of the viruses invading the human body is greatly reduced.

The housing 1 defines a first flow path 13 and a second flow path 16. The first flow path 13 is in partial communication with an outlet 14 for the cleaning liquid 12. In this way, when the portion of the cleaning liquid 12 is disposed within the housing 1, the outflow port 14 from the cleaning liquid 12 may flow into the first flow path 13. The flow control member 2 is disposed at the upstream outlets 13 ', 16' of the first and

13, 16 defining a venturi structure at a location upstream of the intersection of the flow control member 2. And the flow control means 2 is configured to restrict, control and/or regulate the flow of fluid 41 within the second flow path 16. Wherein the flow rate of the fluid 41 in the third flow path 21 is controlled by the suction port 18 of the housing 1

Fig. 5 is a schematic illustration of a spray nasal irrigation device of an irrigation system, a schematic flow diagram of an irrigation system including a spray nasal irrigation device according to a first embodiment. The cleaning liquid system includes a storage space 11, a cleaning liquid 12, and a first flow path 13. The housing 1 includes at least one insulating body 15 disposed in the storage space 11. The insulating body 15 may be, for example, any structural part and/or structural member of the housing 1 within the storage space 11 thereof. The partition 15 is configured to separate and/or divide the storage space 11 into the first flow path 13 and the second flow path 16.

As shown, the cleaning liquid 12 is arranged in the storage space 11 of the housing 1 and is guided out by the fluid 41 in the second flow path 16 at the upstream outlets 13 ', 16' by the upstream 23 of the flow control member 2 with the outflow opening 14 at the bottom of the first flow path 13. The first flow path 13 and the second flow path 16 are each configured to contain a fluid 41 for transporting the cleaning fluid 12. As shown in fig. 5, the spray nasal irrigation device comprises a housing 1 and a flow control member 2. The housing 1 defines a first flow path 13 and a second flow path 16, the first flow path 13 and the second flow path 16 being separately spaced downstream of the housing 1, the first flow path 13 and the second flow path 16 being spaced from and adjacent to each other at an upstream outlet 13 ', 16' of the housing 1. The flow control member 2 is disposed at the upstream outlets 13 ', 16' of the first and

second flow paths

13, 16, the third and

fourth flow paths

21, 22 of the flow control member 2 are spaced apart and adjacent downstream, the third and

fourth flow paths

21, 22 are in upstream fluid communication 41, in other words, the third and

fourth flow paths

21, 22 intersect at the upstream point 23, and the third and

fourth flow paths

21, 22 intersect. A portion of the flow control member 2 defines a venturi structure in the third flow path 21 at a location upstream 23 of the intersection of the third flow path 21 and the fourth flow path 22. In other words, a portion of the third flow path 21 and the fourth flow path 22 includes a converging portion having an inlet end 211 (having a first diameter) and an outlet end 212 (having a second diameter smaller than the first diameter).

The housing 1 of the spray nasal irrigation device is configured to accommodate at least a portion of the outflow 14 portion of the cleansing liquid 12. In this way, the outflow 14 portion of the washing liquid 12 and the fluid 41 of the first flow path 13 are guided out at the upstream outlets 13 ', 16' by the upstream 23 of the flow control member 2. Thus, as described in more detail herein, the outflow 14 from the washing liquid 12 may be conveyed from the outlet line output fluid 41 of the air pump 4 to the flow control member 2 via the first flow path 13. In addition, the air pump 4 determines the output parameters of the time curve of the outflow of the fluid 41 upstream of the flow control member 2, such as the injection pre-pressure, the injection frequency, the outflow interval ratio and the phase relationship between the outflow interval and the interval of the cleaning fluid 12, which can be individually adjusted or changed, so that the flow control member 2 can directly or intermittently output the spray.

The flow control member 2 is disposed at a position upstream of the first flow path 13 and the second flow path 16. In other words, the flow control member 2 is disposed within the first and

second flow paths

13, 16 at a position upstream of the outlets 13 ', 16' of the first and

second flow paths

13, 16. The flow control means 2 is configured to restrict, control and/or regulate the flow of the cleaning liquid 12 within the first flow path 13. The flow control means 2 is an insert means defining upstream outlets 13 ', 16' through its first and

second flow paths

13, 16.

Fig. 6 and 7 are cross-sectional views of a flow control member 2 according to an embodiment, the flow control member 2 including a cover 2A and a nozzle 2B. The outer cover 2A includes a first end portion (i.e., an inlet end 211 portion of the fluid 41), a second end portion (i.e., an outlet end 212 portion of the fluid 41), and an ejection portion 213 (i.e., a diverging portion of the third flow path 21). The first end portion of the outer lid 2A defines a third flow path 21. The first end portion of the outer lid 2A comprises a raised region 19 disposed at the upstream outlets 13 ', 16' of the first and

second flow paths

13, 16. The nozzle 2B is provided with an annular portion correspondingly engaging the second flow path 16 and a through hole 26 passing through the third flow path 21, the nozzle 2B is provided with a fourth flow path 22 and a third flow path 21 formed together with the cover 2A, respectively, the fourth flow path 22 and the third flow path 21 are correspondingly connected to the upstream outlets 16 ', 13' of the second flow path 16 and the first flow path 13, respectively, the fourth flow path 22 is communicated to the first flow path 13, and the third flow path 21 is provided with a plurality of through holes 26.

In use, the housing 1 receives the cleansing liquid 12 from the storage space 11 via the side opening 17 (as shown in fig. 4 and 8), the side opening 17 is sealed by the side cover 3, and the cleansing liquid 12 is sent to the spray nasal irrigation device via the first flow path 13 and an outlet 14 portion of the cleansing liquid 12. The outlet end 212 of the third flow path 21 of the flow control member 2 is a first opening 24 which intersects the fourth flow path 22 as a second opening 25, wherein the opening diameter of the first opening 24 is larger than the opening diameter of the second opening 25, and the first opening 24 of the flow control member 2 is connected and communicated with the second opening 25. More specifically, the fluid 41 from the housing 1 is injected into the second opening 25 for transport to the cleaning fluid 12 via the fourth flow path 22 when the flow rate of the fluid from the first opening 24 of the flow control member 2 increases and the pressure decreases through the first opening 24 of the third flow path 21. In this embodiment, the housing 1 may include a suction port 18 for controlling the flow of the fluid 41 into the third flow path 21, and the flow rate of the fluid 41 in the third flow path 21 is controlled by the suction port 18 of the housing 1. In other words, the flow control member 2 adjusts the ratio of the fluid 41 of the cleaning liquid 12 entering the second flow path 16 at the first flow path 13. For example, the first opening 24 of the third flow path 21 having a large diameter may allow more washing liquid 12 to be injected into the second opening 25 through the fourth flow path 22 than the fourth flow path 22 having a small diameter in the flow control member 2.

When the cleaning liquid 12 is directed through the fluid 41 of the third flow path 21 and through the first opening 24 at the upstream 23, the local pressure of the fluid 41 in the portion of the fourth flow path 22 adjacent to the first opening 24 at the upstream 23 is reduced compared to the pressure of the fluid 41 in the remaining portion of the fourth flow path 22. In other words, a local low pressure zone and/or vacuum is created when the cleaning liquid 12 passes through the first opening 24 at the upstream 23 of the third flow path 21. Thus, the vacuum causes the cleaning liquid 12 to be drawn from the first flow path 13 of the storage space 11 into the fourth flow path 22. The cleaning liquid 12 flowing through the fourth flow path 22 is combined with the fluid 41 flowing through the third flow path 21, and the second opening 25 of the flow control member 2 enables a spray cleaning operation to be performed on the throat, the nasal cavity, and the like, thereby achieving a deep cleaning and care effect. In this way, fluid 41 may be conveyed from the second flow path 16 of the air pump 4 to the third flow path 21 of the flow control member 2 and adjacent to the fourth flow path 22 of the cleaning liquid 12 to prevent a break of the cleaning liquid 12.

Although the cleaning liquid 12 is illustrated as being disposed within the storage space 11 of the housing 1 in fig. 5, if more than two portions are used within the storage space 11 of the housing 1, the cleaning liquid 12 may be disposed within any of the formed portions. Although the cleaning liquid 12 is shown as being disposed within the storage space 11, the cleaning liquid 12 may alternatively be disposed and secured outside the storage space 11.

Although the flow control means 2 is shown and described above as being configured to be disposed at least in part of the upstream outlets 13 ', 16' of the first and

second flow paths

13, 16 of the housing 1. In other words, the upstream outlets 13 ', 16' of the flow control member 2 disposed in the first flow path 13 and the second flow path 16 of the housing 1 may be directly coupled in any suitable manner. In other words, the flow control member 2 may be connected to the upstream outlets 13 ', 16' of the first and

second flow paths

13, 16 of the housing 1 without any intervening structures (e.g. without any hoses, clamps, fittings, etc.).

Although the third and

fourth flow paths

21, 22 of the flow control means 2 are shown as converging from a first diameter to a second diameter smaller than the first diameter, in other embodiments the third and

fourth flow paths

21, 22 may each comprise both converging and diverging portions. The fourth flow path 22 of the flow control member 2 comprises a converging portion at upstream 23 and the third flow path 21 comprises a converging portion and a diverging portion at upstream 23. In this way, as the fluid 41 flows through the third flow path 21 and through the upstream 23, the local pressure of the fluid 41 within the portion of the fourth flow path 22 located at the upstream 23, the lowest pressure occurring substantially adjacent to the throat (i.e., the portion of the upstream 23 having the smallest diameter).

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
