Description

nasal aspirator

technical field

The invention relates to the field of daily necessities, in particular to a nasal aspirator.

Background technique

For example, infants and young children under the age of 3, ordinary people who are elderly or seriously ill, and even some animals that are not yet born, usually do not have the ability to voluntarily discharge nasal secretions. Excessive nasal secretions will block the nostrils, causing poor breathing and nasal ulceration, and the blocked nostrils will cause nasal secretions to flow back into the lungs and may cause lung inflammation. Therefore, in order to remove nasal secretions, people invented nasal aspirators.

Traditional nasal aspirators usually include a pipeline with an inlet at one end, a liquid storage bottle for storing nasal mucus in the middle of the pipeline, and an outlet at the tail end. During use, negative pressure is formed by pumping air at the outlet, so that nasal mucus enters the pipeline from the inlet and is left in the liquid storage bottle.

In order to obtain suction, when using the simplest nasal aspirator, people usually use their mouth to inhale against the outlet, thereby creating negative pressure. When using the mouth to inhale, sometimes the nasal mucus will be accidentally sucked into the mouth, which is very disgusting and unhygienic. Even if the snot is not sucked into the mouth, using a nasal aspirator on someone who may be sick can still cause discomfort.

In order to overcome this problem, people also use an electric vacuum pump to connect to the outlet as a power source for negative pressure. However, the introduction of high-power electrical equipment will bring about many problems such as rising costs, complicated maintenance, and inconvenient cleaning. It is not suitable for ordinary household use. The introduction of low-power electrical equipment will cause insufficient suction and insufficient versatility.

Based on the idea of non-electric equipment, some people have given a more compromise solution. They adopt the mode of connecting the suction airbag at the outlet, and utilize the negative pressure that the suction airbag produces to draw air outwards to provide suction. However, because when using the nasal aspirator, the user needs to hold the end of the pipe with one hand and keep the inlet connected to the patient's nostril, and can only operate the nasal aspirator with one hand with the other hand, so it is usually aspiration The volume of the airbag will not exceed the size of holding it with one hand, and its suction is very limited, which is difficult to meet the needs of use.

Contents of the invention

The object of the present invention is to provide a nasal aspirator which is reliable and hygienic and has greater suction power.

In order to solve the above technical problems, the present invention provides a nasal aspirator, including a pipeline, a valve arranged on the pipeline and a negative pressure member connected to the pipeline;

There is an inlet at one end of the pipeline, and the valve is located between the inlet and the negative pressure part;

There is also an outlet on the pipeline, and the negative pressure part is located between the inlet and the outlet, and the outlet can be closed to prevent gas from entering the pipeline;

When the valve is closed, the outlet exhausts outward, and the negative pressure part forms a negative pressure; the outlet is closed after the negative pressure part forms a negative pressure; the valve is opened, so that the inlet sucks air into the pipeline.

It is worth mentioning that, in the present invention, there is no limit to the power source when the outlet exhausts outwards. It can be inhaled by the mouth, can also be inhaled by hand, or even can be inhaled by a vacuum pump. Since there is no need to continuously inhale during use, there is no risk of nasal mucus being sucked into the power source, which is very reliable and hygienic.

Compared with the technical solution in the prior art where the air bag is directly connected to the outlet, since the valve is provided in the present invention, the user only needs to block the outlet by hand to store the required negative pressure in the negative pressure member. In the process, the valve is opened to absorb nasal secretions when needed. Therefore, compared with the traditional suction air bag, the negative pressure part adopts a larger volume and a more elastic material, so as to obtain stronger suction.

Preferably, a one-way valve is arranged on the outlet. When the one-way valve is set on the outlet, after the required negative pressure is obtained, the nasal aspirator can be kept in a negative pressure state without blocking the outlet, and is not limited by one-handed operation, making the use easier and more convenient.

Further, preferably, the nasal aspirator further includes a suction airbag connected to the one-way valve. The suction airbag is used as the power source of the negative pressure, which has low cost and is easy to operate. Wherein, the elasticity of the negative pressure part is stronger than that of the suction air bag; or, the volume of the negative pressure part is larger than that of the suction air bag. At this time, the negative pressure member can provide as large a negative pressure as possible by repeatedly pressing the suction air bag several times.

In addition, preferably, the nasal aspirator also includes an electric air suction pump, and the electric air suction pump is connected to the one-way valve;

A negative pressure sensor is also arranged in the nasal aspirator, and the negative pressure sensor is communicated with the electric air suction pump.

Apparently, those of ordinary skill in the art should know that the negative pressure sensor can be arranged at any position before the one-way valve in the nasal aspirator, and used to detect the pressure in the pipeline.

Moreover, after the negative pressure sensor sends the pressure signal to the electric air pump, when the pressure reaches a preset value, the electric air pump can automatically stop pumping, thereby realizing automatic control and making it more convenient for one-handed operation.

Further, preferably, the valve is an electronic valve, and the negative pressure sensor is also communicated with the valve. At this time, the negative pressure sensor also sends a pressure signal to the electronic valve, and when the pressure in the pipeline reaches a given value, the valve is automatically opened , you can achieve the suction action of nasal secretions.

In addition, preferably, the nasal aspirator is provided with a liquid storage bottle for storing nasal mucus, and the bottom of the liquid storage bottle is also provided with a counterweight. When the bottom of the bottle is provided with a counterweight, it can prevent the liquid storage bottle from turning over, so as to better prevent nasal secretions from flowing back, and reduce the difficulty of cleaning and cleaning.

The liquid storage bottle is provided with a cover, and the cover is provided with a cover hole, and the negative pressure part communicates with the liquid storage bottle through the cover hole. When a liquid storage bottle is provided, the negative pressure part is arranged above the liquid storage bottle, and communicated with the liquid storage bottle through the cover hole provided on the cover, which can effectively prevent nasal secretions from entering the negative pressure part, and cooperate with Counterweights are more effective.

Or, preferably, the reservoir is located between the valve and the inlet. The liquid storage bottle is set between the valve and the inlet, and the nasal secretion will directly enter the liquid storage bottle after entering from the inlet without going through the valve, so it is easier to clean and cleaner.

In addition, preferably, the valve includes a switch, a partition plate and a rotating shaft, the partition plate is connected to the switch, the switch is connected to the rotating shaft, and the switch can drive the partition plate to flip along the rotating shaft to open and close the valve. The turning of the partition plate is controlled by the rotating shaft, and the airtightness of the valve is more easily controlled.

Furthermore, preferably, the valve further includes a torsion spring, which is sleeved on the rotating shaft, pushes the partition plate and tends to close the partition plate. Utilizing the torsion spring can make the partition plate in the closed state when it is not operated, thereby reducing the operation of the switch and making it more convenient.

In addition, preferably, the inner diameter of the part of the pipe near the inlet is smaller than the inner diameter of the part away from the inlet. The part with a larger inner diameter has a larger gas passage, and can get enough negative pressure faster, while the part with a smaller inner diameter forms a faster flow rate and stronger suction.
