A split-type nasal aspirator

Abstract

This utility model relates to a split-type nasal aspirator, comprising a body, an inhalation head, and a conduit. The body and the inhalation head are detachably connected via the conduit. The body includes a first shell, a second shell, and an inhalation pump. The first shell is hollow, forming a receiving cavity, and its surface has a first air inlet and a first air outlet. The second shell is hollow, forming a slow-flow cavity, and its surface has a second air inlet and a second air outlet. The first and second shells are detachably connected, with the first air inlet abutting against the second air outlet. The second air inlet is detachably connected to the conduit, and the first air outlet communicates with the outside. The inhalation pump is located within the receiving cavity, with its inlet end communicating with the first air inlet and its outlet end communicating with the first air outlet. This utility model combines the receiving cavity and the slow-flow cavity through the design of the slow-flow cavity. When airflow enters the slow-flow cavity from the conduit, the flow velocity decreases due to the increased flow cross-section, making it easier for nasal mucus carried by the airflow to separate and remain within the slow-flow cavity under gravity.

Description

Technical Field

[0001] This utility model relates to the field of maternal and infant care technology, specifically to a split-type nasal aspirator. Background Technology

[0002] Infants are prone to colds due to their weaker constitution, often accompanied by runny nose. Before they learn to blow their noses on their own, parents often need to help clean their noses. Otherwise, the dried mucus will form nasal crusts that block the nasal cavity, thus affecting the child's breathing.

[0003] Nasal aspirators, as an auxiliary tool, can remove mucus from an infant's nasal cavity. Most commonly used nasal aspirators currently use an air pump to suction the mucus from the infant's nasal cavity into the suction chamber. However, during the use of a nasal aspirator, if there is too much mucus in the suction chamber, the mucus can easily be sucked into the air pump, causing airway blockage and bacterial growth, which affects the long-term use of the nasal aspirator. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a split-type nasal aspirator to prevent nasal mucus from entering the air pump and causing airway blockage and bacterial growth, thereby extending the service life of the nasal aspirator.

[0005] A split-type nasal aspirator includes a body, an inhalation head, and a conduit. The body and the inhalation head are connected via the conduit. The body includes a first housing, a second housing, and an inhalation pump. The first housing is hollow, forming a accommodating cavity, and its surface has a first air inlet and a first air outlet. The second housing is hollow, forming a slow-flow cavity, and its surface has a second air inlet and a second air outlet. The first housing and the second housing are detachably connected. The first air inlet abuts against the second air outlet. The second air inlet is detachably connected to the conduit, and the first air outlet communicates with the outside. The inhalation pump is located within the accommodating cavity, with its inlet end communicating with the first air inlet and its outlet end communicating with the first air outlet.

[0006] This invention features a slow-flow chamber. When airflow enters the slow-flow chamber through the conduit, the flow velocity decreases due to the increased cross-sectional area, making it easier to separate the mucus carried by the airflow. Under the influence of gravity, the mucus remains in the slow-flow chamber, effectively preventing mucus from entering the inhalation pump, reducing pump blockage and bacterial growth, and extending the lifespan of the nasal aspirator.

[0007] As a preferred embodiment, the device body further includes a flow damper located within the flow damping cavity, which isolates the second air inlet and the second air outlet, preventing airflow convection between them. By placing the flow damper on the line connecting the second air inlet and the second air outlet, the residence time of the airflow within the flow damping cavity is increased, preventing the airflow from directly entering the second air outlet from the second air inlet, thus separating nasal mucus from the airflow and preventing nasal mucus from entering the inhalation pump.

[0008] As a preferred embodiment, an exhaust chamber is formed at the connection between the first housing and the second housing, and the first air outlet is located within the exhaust chamber, which is in communication with the outside. Airflow can be guided out of the suction pump through the exhaust chamber.

[0009] As a preferred embodiment, the suction head further includes a suction chamber cover and a suction nozzle connected to the suction chamber cover. The suction chamber cover has a hollow structure to form a suction chamber, and the suction chamber cover is detachably connected to the conduit.

[0010] As a preferred embodiment, the inhalation head includes a flow guide bracket disposed within the suction chamber. One end of the flow guide bracket is connected to the conduit, and the other end is closed. A third air inlet is provided on the side of the flow guide bracket. The flow guide bracket forms a mutually separated baffle cavity and a flow guide groove, with the third air inlet located within the baffle cavity. When nasal mucus enters the suction chamber, it is isolated by the baffle cavity of the flow guide bracket and flows downward along the flow guide groove, preventing it from entering the third air inlet and reducing the amount of nasal mucus carried by the airflow into the inhalation pump.

[0011] As a preferred embodiment, the airflow guide bracket includes a bracket body and two arc-shaped baffles; the arc-shaped baffles form the airflow-blocking cavity, and the two arc-shaped baffles are respectively vertically disposed on the side walls of both sides of the bracket body with their openings facing outwards; a third air inlet is respectively opened on the side wall of the bracket body at the corresponding position of each of the arc-shaped baffles; the two arc-shaped baffles and the outer side of the bracket body enclose the airflow guide groove. Through the structural design of the airflow guide bracket, nasal mucus is encouraged to fall from the airflow guide groove and avoid entering the third air inlet.

[0012] As a preferred embodiment, the suction nozzle is angled relative to the suction chamber cover. This angled arrangement facilitates the user inserting the nozzle into the nasal cavity.

[0013] As a preferred embodiment, the housing further includes a battery, and the first housing also has a charging port. The battery is fixed within the accommodating cavity, and the charging port is connected to the battery. The battery can be charged through the charging port.

[0014] As a preferred embodiment, the device also includes a control panel, which is electrically connected to the battery and the suction pump. The control panel allows control of the battery and the suction pump.

[0015] As a preferred embodiment, the device also includes a music player, and the first housing is further provided with a speaker opening. The music player is located within the receiving cavity and abuts against the speaker opening. When suctioning the nose, the infant may exhibit tension and resistance; playing music through the speaker can distract the infant and facilitate the suctioning process. Attached Figure Description

[0030] like Figure 1-7As shown, the present invention discloses a split-type nasal aspirator, comprising a body 1, an inhalation head 2, and a conduit 3, wherein the body 1 and the inhalation head 2 are detachably connected via the conduit 3. The body 1 includes a first housing 11, a second housing 12, a flow damper 13, an air pump 14, a battery 15, a speaker 16, and a control panel. The first housing 11 and the second housing 12 are rectangular hollow structures. The first housing 11 has a first air inlet 111, a first air outlet 112, a waterproof charging port 113, and a music playback port 114. The second housing 12 is a rectangular hollow structure, and the second housing has a second air inlet 121 and a second air outlet 122. The hollow structure inside the first housing 11 forms a sealed accommodating cavity 41, and the hollow structure inside the second housing 12 forms a sealed slow-flow cavity 42. The first housing 11 and the second housing 12 are detachably connected, and the connection point forms an exhaust cavity 43. The first air inlet 111 abuts against the second air outlet 122, and the second air inlet 121 is detachably connected to the conduit 3. The first air outlet 112 is located inside the exhaust cavity 43, and the exhaust cavity 43 is connected to the outside.

[0031] The air pump 14, battery 15, horn 16, and control panel are located within the accommodating cavity 41. The air inlet of the air pump 14 is connected to the first air inlet 111, and the air outlet of the air pump 14 is connected to the first air outlet 112. The battery is connected to a waterproof charging port 113, which can be any of the following interfaces: Type-C, Lightning, or USB. Figure 4 As shown, this embodiment uses a Type-C waterproof charging port. The speaker 16 covers the music playback port 114, and the connection between the first housing 11 and the speaker 16 is covered with sealant to waterproof the music playback port. The control panel includes a control circuit board 171, control buttons 172, and indicator lights 173. The control circuit board 171 is electrically connected to the air pump 14, battery 15, and speaker 16, and can load control programs to control the suction power of the air pump 14 and the on / off state of the battery 15 and speaker 16. The control buttons 172 and indicator lights 173 pass through the first housing 11; the indicator lights 173 indicate the working status of the nasal aspirator and the battery level.

[0032] The flow buffer 13 is located inside the flow buffer cavity 42 and is vertically arranged on the line connecting the second air inlet 121 and the second air outlet 122. It separates the second air inlet 121 and the second air outlet 122, avoids airflow convection between the second air inlet 121 and the second air outlet 122, and further reduces the airflow velocity in the flow buffer cavity 42, so that the nasal mucus carried by the airflow falls into the flow buffer cavity 42 and is prevented from entering the inhalation pump 14.

[0033] like Figure 8-9As shown, the suction head 2 includes a nozzle 21, a flow guide bracket 22, and a suction chamber cover 23. The suction chamber cover 23 has a hollow structure, forming a suction chamber 44. The flow guide bracket 22 is located inside the suction chamber 44, with one end connected to the second air inlet 121 via a conduit 3, and the other end closed. A third air inlet 221 is provided on the side of the flow guide bracket 22. The flow guide bracket 22 forms mutually separated flow-blocking cavities 222 and flow-guiding grooves 223. The third air inlet 221 is located inside the flow-blocking cavity 222. Specifically, the flow guide bracket 22 includes a bracket body 224 and two arc-shaped flow-blocking plates 225. The two arc-shaped flow-blocking plates 225 are respectively vertically arranged on the side walls on both sides of the bracket body 224 and have their openings facing outward to form the flow-blocking cavity 222. The bracket body 224 and the two arc-shaped flow-blocking plates 225 enclose each other to form a flow-guiding groove 223. Each bow-shaped baffle 225 includes a first baffle 2251, a second baffle 2252, and a third baffle 2253. The first baffle 2251 is disposed on the side wall of the support body 224, and the third air inlet 221 is opened at the corresponding position of the support body 224 and the first baffle 2251. The two sides of the first baffle 2251 extend outward toward the support body 224 to form the second baffle 2252 and the third baffle 2253, respectively. Preferably, the second baffle 2252 is larger than the third baffle 2253, and the side of the second baffle 2252 away from the support body 224 extends downward at an angle toward the side closer to the support body 224, while the side of the third baffle 2253 close to the support body 224 extends downward at an angle toward the side away from the support body 224. When nasal mucus enters the suction chamber 44, it is isolated by the arc-shaped baffle 225 of the flow guide 22 and guided downward through the flow guide groove 223. This allows the flow guide 22 to block and guide the nasal mucus, preventing it from being sucked into the catheter 3.

[0034] This nasal aspirator effectively prevents mucus from entering the inhalation pump 14 by combining the receiving cavity 41 and the slow-flow cavity 42. Firstly, when airflow enters the slow-flow cavity 42 through the conduit 3, the increased space and decreased flow velocity make it easier to separate the mucus carried by the airflow, which then remains within the slow-flow cavity 42 under gravity. Secondly, a slow-flow plate 13 is provided on the line connecting the second air inlet 121 and the second air outlet 122, increasing the residence time of the airflow within the slow-flow cavity 42 and preventing the airflow from directly entering the second air outlet 122 from the second air inlet 121, thus separating the mucus from the airflow and preventing it from entering the inhalation pump 14. Furthermore, the specific structural design of the guide bracket 22 further enhances the effectiveness of this nasal aspirator in preventing mucus from entering the inhalation pump 14 during nasal aspiration. The horn 16 can distract the infant's attention with sound and light, making the nasal aspiration process more time-saving and effortless. The waterproof charging port 131 is used to charge the battery 15. The indicator light 173 indicates the working status of the nasal aspirator and the battery level.

[0035] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
