Description

Technical Field

[0001] The utility model belongs to the field of auxiliary appliances, and particularly relates to a nasopharyngeal irrigator. Background Art

[0002] At present, as a tool for flushing the nasal cavity, a nasal cavity irrigator uses a certain pressure to send physiological saline into the nasal cavity, and adjusts the pressure input at the air inlet end by squeezing, so as to control the water flow rate, clean the accumulated secretions and harmful impurities in the nasal cavity, and keep the nasal cavity clean. Relying on the bactericidal effect of physiological saline and the impact force of the water flow, the germs in the nasal cavity are discharged, the normal physiological environment inside the nasal cavity is restored, its self-detoxification function is guaranteed to recover, and the nasal mucosa can be stimulated during the cleaning process to promote the normal operation of the nasal mucosa, improve the state of the nasal mucosa, and it has been widely used in the subsequent treatment of nasal cavity and sinus diseases.

[0003] At present, the commercially available nasal cavity irrigators cannot deeply clean the nasal cavity of patients. They can only send physiological saline into the nostrils through the nozzle, and then discharge it through the nasal vestibule, nasal sinuses, nasal passages and then through the oral cavity. The physiological saline cannot or can only rarely clean the deeper part of the nasal cavity. On the one hand, most of the current nasal cavity irrigators cannot accurately adjust the water flow rate, which to a certain extent affects the flushing effect. If the water flow rate is too fast, it may cause discomfort to the patient, while if the water flow rate is too slow, it may affect the cleaning effect and cannot perform the flushing operation better; on the other hand, the nasal cavity irrigator is generally of a detachable structure, and the current detachable nasal cavity irrigator has many connecting parts, is not easy to carry, and is inconvenient to use. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a nasopharyngeal irrigator, which is provided with a flow regulating device. The cooperation of the flow regulating device and the V-shaped elbow realizes the regulation of the output flow of the liquid medicine in the main body of the bottle; and its overall structure has fewer connecting parts, is easy to carry and can atomize the water flow, and has a good flushing effect. At the same time, the setting of the second end of the nose adapter of the device enables it to contact the nasal cavity more fully, so that the nozzle can directly clean the nasopharynx.

[0005] To achieve the above object, the utility model discloses the following technical solutions:

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model adopts a V-shaped elbow design in terms of structure, which effectively slows down the situation of too fast flow rate caused by the direct impact of liquid when the bottle body is inverted. By changing the shape of the elbow, the liquid is hindered and buffered during the flowing process, thereby stabilizing the liquid outlet rate and avoiding the occurrence of choking due to too fast flow rate. The user can perform nasopharyngeal irrigation work in a relatively relaxed state. At the same time, due to the stability of the liquid outlet rate, the needs of more different users can be met.

[0017] The utility model is provided with a first fastening block, a second fastening block and a dial at the upper end of the connecting cover and the elbow joint. By rotating the dial to change its position, the inlet and outlet areas are adjusted, and then the effect of controlling the water flow speed is achieved until the appropriate water flow speed is adjusted.

[0018] The utility model is equipped with a nose adapter at the elbow. The second end of the nose adapter is a frustum structure, which can effectively fit the human nostrils, is more comfortable and easier to fit during use, and can not only improve the comfort, but also reduce the loss and pollution of the liquid medicine.

[0019] The utility model is provided with a nozzle behind the nasal cavity adapter. The nozzle is made of rubber material and is designed to be slender, and can penetrate deep into the nasal cavity to ensure that the physiological saline can cover every corner of the nasal cavity. By penetrating the nozzle deep into the nasal cavity, it is ensured that the physiological saline is flushed into the corner of the nasal cavity, effectively removing the secretions, germs and other harmful substances in the nasal cavity.

[0020] The utility model adopts a porous design at the nozzle. When the physiological saline passes through, it will be atomized into fine water flows, which can better enter the nasal cavity through the fluid elbow. This porous design slows down the impact of the physiological saline on the nasopharynx and avoids the discomfort and damage caused by direct flushing. Under the combined action of the nose adapter and the nozzle, the loss of the liquid medicine during the flushing process is reduced, and the contact area between the liquid medicine and the air is also reduced, reducing the risk of the liquid medicine being contaminated.

[0021] The overall structure of the utility model is simple, the installation is convenient, and it is easy to disassemble and clean; after unscrewing the dust-proof cover, it can be used after adding physiological saline, reducing the pollution of the inside of the liquid storage bottle body due to long-term placement, and being safer and more hygienic; the bottle body is designed compactly and has fewer structural parts, and it can also be easily carried by users who go out and perform nasal cavity irrigation operations at any time.

[0036] The connecting device includes a connecting cap 7, a V-shaped elbow 2, and a nose adapter 5. The first end of the connecting cap 7 is provided with an internal thread structure that matches the external thread structure of the hollow protrusion 8. The second end of the connecting cap 7 is nested and connected to the first end of the V-shaped elbow 2. The second end of the V-shaped elbow 2 is movably nested and connected to the first end of the nose adapter 5, and the V-shaped elbow 2 and the nose adapter 5 are in a communicating state. The second end of the nose adapter 5 is connected to the first end of the nozzle 6, and a sealing ring is provided on the side wall of the nozzle 6. The nose adapter 5 and the elbow joint are nested and connected, so as to better adjust the length of the nose adapter 5 to meet the needs of different users. Moreover, a sealing ring is provided on the side wall of the nose adapter 5 at the connection between the nose adapter 5 and the V-shaped elbow 2, ensuring that the liquid medicine does not leak during the movement of the nose adapter 5.

[0037] A flow regulating device 4 is provided on the V-shaped elbow 2; the flow regulating device 4 includes a first fastening block 9, a second fastening block 10, and a dial 11. The first fastening block 9, the second fastening block 10, and the dial 11 are concentrically arranged, and the centers of the first fastening block 9, the dial 11, and the second fastening block 10 are connected by a connecting shaft.
