技术领域technical field
本发明属于鼻腔清洗技术领域，特别涉及一种口呼气传感的电动鼻腔冲洗器。The invention belongs to the technical field of nasal cavity cleaning, and in particular relates to an electric nasal cavity irrigation device with mouth and exhalation sensing.
背景技术Background technique
鼻炎、鼻窦炎、上呼吸道感染等多种上呼吸道疾病有着很高的发病率和复发率，除了常用的药物治疗，鼻腔清洗是临床治疗中一种常用的手段，鼻腔清洗可清除鼻腔粘膜异常分泌物、减轻黏膜水肿和炎症，能够明显改善患者症状。Rhinitis, sinusitis, upper respiratory tract infection and other upper respiratory diseases have a high incidence and recurrence rate. In addition to commonly used drug treatment, nasal cleaning is a common method in clinical treatment. Nasal cleaning can remove abnormal secretion of nasal mucosa Drugs, reduce mucosal edema and inflammation, can significantly improve the symptoms of patients.
目前使用的鼻腔清洗设备有多种类别，其中电动洗鼻器因其采用电动控制方式，可以更好地保证清洗过程的稳定可控，在医院和家庭中广受欢迎。常用的电动洗鼻器采用微型水泵将液杯中的洗鼻液泵出至一侧鼻腔，然后绕过鼻中隔从另一侧鼻腔流出，完成鼻腔的冲洗清洁。但这类电动洗鼻器存在若干缺陷：一方面清洗后流出的洗鼻废液使得场地脏污并造成清理不便，导致使用者常在洗手池、卫生间等不理想的环境中进行鼻腔冲洗；另一方面压力推动的水流冲击软腭容易导致软腭闭合不完全，洗鼻液呛流口咽通道，会引起呛水等不适， 严重的可能对使用者造成危害。There are many types of nasal cleaning equipment currently in use. Among them, electric nasal irrigators are popular in hospitals and families because they adopt electric control methods, which can better ensure the stability and controllability of the cleaning process. The commonly used electric nasal irrigator uses a micro-pump to pump the nasal rinsing solution in the liquid cup to one nasal cavity, and then bypasses the nasal septum to flow out from the other nasal cavity to complete the cleaning of the nasal cavity. However, there are some defects in this type of electric nasal irrigator: on the one hand, the nasal rinsing waste liquid that flows out after cleaning makes the site dirty and causes inconvenience in cleaning, causing users to often perform nasal cavity irrigation in unsatisfactory environments such as sinks and toilets; On the one hand, the impact of the water flow driven by the pressure on the soft palate will easily lead to incomplete closure of the soft palate, and the nasal wash will choke the oropharyngeal passage, causing discomfort such as choking water. Seriously, it may cause harm to users.
专利文献CN105873625B和US10525240B1都公开了一种呼吸驱动的洗鼻壶，洗鼻液杯倒置后在杯口设置有鼻腔接头和口呼气含嘴，使用者通过口呼气含嘴向洗鼻液杯内吹入空气，此时鼻腔接头打开，洗鼻液的重力作用和吹入空气的压力促使洗鼻液进入鼻腔进行冲洗。由于人体在口呼气时，口咽部的软腭由于呼吸道上行的气体在下部形成正压，软腭处于关闭状态，可以降低清洗过程中呛水的风险。然而该方式下，洗鼻液的流速和压力受口呼气气流大小和时间的影响，对使用者的配合要求较高，不太方便儿童、老人或呼吸疾病患者等人群的使用，如果使用者吹气气流太小则无法推进洗鼻液的有效流动，或者吹气气流太大导致鼻腔内液体压力过大，仍会导致呛水或水流入中耳等问题的发生。Patent documents CN105873625B and US10525240B1 both disclose a breath-driven neti pot. After the nasal wash cup is inverted, a nasal joint and a mouthpiece are provided at the mouth of the cup. Air is blown inside, and the nasal cavity connector is opened at this time, and the gravity action of the nasal wash liquid and the pressure of the blown air impel the nasal wash liquid to enter the nasal cavity for rinsing. When the human body exhales from the mouth, the soft palate of the oropharynx forms a positive pressure in the lower part due to the upward gas in the respiratory tract, and the soft palate is in a closed state, which can reduce the risk of choking on water during the cleaning process. However, in this mode, the flow rate and pressure of the nasal wash are affected by the size and time of the mouth-exhaled airflow, which requires high cooperation from the user, and is not very convenient for children, the elderly or patients with respiratory diseases. If the user If the blowing airflow is too small, the effective flow of the nasal wash cannot be promoted, or if the blowing airflow is too large, the liquid pressure in the nasal cavity will be too high, which will still cause problems such as choking or water flowing into the middle ear.
因此，目前仍缺少各类使用人群都能方便控制和使用的鼻腔冲洗器。Therefore, there is still a lack of nasal irrigation devices that can be conveniently controlled and used by various user groups.

冲洗液容器设置于鼻腔接头和流出液容器的上方；更进一步地，流出液容器设置于鼻腔接头的下方。 The flushing liquid container is arranged above the nasal cavity connector and the outflow liquid container; further, the outflow liquid container is arranged under the nasal cavity connector.
进一步地，冲洗液容器的底部还设置有阀，阀的开启力大于冲洗液的自重压力，即阀在闭合状态时可以阻止冲洗液流出；当阀被施以叠加的外力时，如上方正压力或下方负压力，且冲洗液的自重压力与外力的叠加之和大于阀的开启力时，阀被置入打开状态，而允许冲洗液流出，当叠加的上方正压力或下方负压力被撤去时，阀回复到闭合状态。Further, a valve is also provided at the bottom of the flushing liquid container, and the opening force of the valve is greater than the self-weight pressure of the flushing liquid, that is, the valve can prevent the flushing liquid from flowing out when the valve is in a closed state; when the valve is applied with superimposed external force, such as positive pressure or Negative pressure below, and the sum of self-weight pressure of the flushing fluid and the superposition of external force is greater than the opening force of the valve, the valve is placed in an open state, allowing the flushing fluid to flow out, when the superimposed positive pressure above or negative pressure below is removed, The valve returns to the closed state.
图5示出了所述实施方案的一种电动鼻腔冲洗器，其设置与实施例1的电动鼻腔清洗器基本一致，包括鼻腔接头1’、控制器2’、电动驱动源22’、口呼气接头3’、冲洗液容器4’和流出液容器5’，部分部件未示出，可参照实施例1理解。不同之处在于：Fig. 5 shows a kind of electric nasal cavity irrigation device of described embodiment, and its setting is basically consistent with the electric nasal cavity cleaning device of embodiment 1, comprises nasal cavity joint 1 ', controller 2 ', electric drive source 22 ', mouth breather The air connector 3', the flushing liquid container 4' and the effluent liquid container 5', some parts are not shown, and can be understood with reference to Embodiment 1. The difference is:
冲洗液容器4’位于鼻腔接头1’的上方，鼻腔接头1’位于流出液容器5’的上方。冲洗液容器4’的底部还设置有阀7’，电动驱动源22’工作时，气流流入冲洗液容器4’,冲洗液容器4’内气压增大，当冲洗液的重力与电动驱动源22’施加在冲洗液上的压力的叠加之和大于阀的开启力时，阀7’被置入打开状态，而允许冲洗液流出，进行鼻腔冲洗。The irrigation fluid container 4' is positioned above the nasal cavity connector 1', and the nasal cavity connector 1' is positioned above the effluent container 5'. The bottom of the flushing liquid container 4' is also provided with a valve 7'. When the electric driving source 22' is working, the air flow flows into the flushing liquid container 4', and the air pressure in the flushing liquid container 4' increases. When the sum of the superimposed pressures applied to the flushing liquid is greater than the opening force of the valve, the valve 7' is placed in an open state, allowing the flushing liquid to flow out for nasal irrigation.
该方案中，采用冲洗液容器中增加的正压作为阀组件的开启力，同时冲洗液容器中的正压力与流出液容器中的负压力的共同作用力驱动冲洗液流动。In this solution, the increased positive pressure in the flushing liquid container is used as the opening force of the valve assembly, and the combined force of the positive pressure in the flushing liquid container and the negative pressure in the effluent container drives the flushing liquid to flow.
作为本实施例的一种变形，所述冲洗液容器4’的上部是与外界空气相通的，电动驱动源22’的出气端不接入冲洗液容器4’。当电动驱动源22’工作时，从流出液容器5’内抽出空气，当使用者的两侧鼻腔与鼻腔接头1’密封连接后，流出液容器5’、液体管路26’内均形成负压，当冲洗液的重力与负压作用力的叠加之和大于阀的开启力时，阀7’被置入打开状态，而允许冲洗液流出，进行鼻腔冲洗。As a modification of this embodiment, the upper part of the flushing liquid container 4' is communicated with the outside air, and the air outlet of the electric driving source 22' is not connected to the flushing liquid container 4'. When the electric driving source 22' works, the air is drawn out from the outflow liquid container 5', and when the user's nasal cavities on both sides are sealed with the nasal cavity connector 1', a negative pressure is formed in the outflow liquid container 5' and the liquid pipeline 26'. When the sum of the gravity of the flushing fluid and the negative pressure is greater than the opening force of the valve, the valve 7' is placed in an open state, allowing the flushing fluid to flow out for nasal irrigation.
在该变形方案中，采用负压作为动力驱动冲洗液流动，同时将负压作为阀组件的开启力，实现了仅在鼻腔具备基本的通气状态时阀才会打开进行冲洗， 若鼻腔严重堵塞，则阀组件不会被打开而不能令液体流进行鼻腔冲洗，可以有效降低鼻腔冲洗液对鼻腔严重堵塞者的鼻腔进行冲击而引起伤害。In this modified scheme, negative pressure is used as the driving force to drive the irrigation liquid to flow, and at the same time, the negative pressure is used as the opening force of the valve assembly, so that the valve will be opened for irrigation only when the nasal cavity is in a basic ventilation state. If the nasal cavity is severely blocked, the valve assembly will not be opened to allow the liquid to flow through the nasal cavity, which can effectively reduce the impact of the nasal cavity washing liquid on the nasal cavity of the person with severe nasal cavity blockage and cause damage.

作为本实施例的一种变形，还可以是，所述电动鼻腔冲洗器不设置流出液容器，仅设置一个鼻腔接头用于将冲洗液导入一侧鼻腔，流出液经另一侧鼻腔直接排出。As a modification of this embodiment, it is also possible that the electric nasal irrigator does not have an effluent container, and only a nasal cavity connector is provided for introducing the rinsing liquid into one nasal cavity, and the effluent is directly discharged through the other nasal cavity.
