Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a suction chamber assembly and a nasal aspirator. Background Technology

[0002] A nasal aspirator, as the name suggests, is a device used to remove nasal discharge from the nasal cavity, replacing the body's natural suction. It is commonly used for patients who are unable to use their lungs to suction nasal mucus due to injury, or for infants and young children who cannot control their bodies. When the body suffers from respiratory illnesses, it often produces nasal mucus or phlegm. If this mucus is not promptly removed from the nasal cavity, it can easily cause nasal congestion and difficulty breathing. Especially for infants and young children, even when using a nasal aspirator, the sensation of a foreign object can cause fear, leading to poor cooperation and making it difficult to perform the necessary suction to relieve their discomfort.

[0003] In addition, in existing nasal aspirators, the suction chamber components are either too complex to clean and reuse, or nasal mucus can easily enter the suction tube or even the main unit, making the device very inconvenient to clean or even unusable. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides a suction chamber assembly and a nasal aspirator.

[0005] Firstly, the suction chamber assembly provided by this utility model includes:

[0006] The suction chamber has a suction nozzle at the top, a pipe connector at the bottom, and a partition plate inside the cavity; and

[0007] The suction chamber support has a hollow structure and extends from the outside of the suction chamber through the pipe joint into the inner cavity of the suction chamber. The top of the suction chamber support is provided with an air intake port communicating with the hollow structure.

[0008] The partition plate separates the suction port of the nozzle from the air intake port on the suction chamber.

[0009] In one embodiment, the suction chamber includes a detachably connected upper suction chamber and a lower suction chamber, the suction nozzle is disposed at the top of the upper suction chamber, the partition plate is disposed inside the upper suction chamber, and the pipe connector is disposed at the bottom of the lower suction chamber.

[0010] In one embodiment, the suction nozzle is tilted and disposed on the suction chamber.

[0011] In one embodiment, the suction nozzle is disposed on one side of the suction chamber.

[0012] In one embodiment, the chamber on the side with the suction port divided by the partition is smaller than the chamber on the side with the air intake port.

[0013] In one embodiment, the suction chamber support is further provided with a horizontal partition, which is located between the air intake and the pipe joint; the air intake is arranged radially along the suction chamber support.

[0014] In one embodiment, the radial edge of the diaphragm is spaced from the partition plate.

[0015] Secondly, the present invention also provides a nasal aspirator, including a main unit, a suction tube, and a suction chamber assembly as described in any of the first aspects of the present invention; one end of the suction tube is connected to the main unit, and the other end is detachably connected to the suction chamber support.

[0016] In one embodiment, the host includes a control circuit board and control buttons, a display screen and a music module connected to the control circuit board, and the host's casing is also provided with a sound outlet.

[0017] In one embodiment, the main unit further includes an air pump and a secondary battery, and the housing of the main unit is also provided with a charging interface, which is electrically connected to the secondary battery.

[0018] The technical solutions provided in the embodiments of this utility model bring the following beneficial technical effects:

[0019] The suction chamber assembly provided by this utility model has a relatively simple structure, consisting only of a suction chamber and a suction chamber support extending into the suction chamber. The suction port on the suction chamber is separated from the air intake port on the suction chamber support by the partition plate inside the suction chamber.

[0034] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0035] An embodiment of the first aspect of this utility model provides a suction chamber assembly 30, such as... Figures 1-4 As shown, it includes a suction chamber 100 and a suction chamber holder 200 inserted into the suction chamber 100. The suction chamber 100 is generally made of plastic and is a container for temporarily storing nasal fluid. The suction chamber holder 200 draws air from the suction chamber 100, creating a negative pressure in the suction chamber 100, which gives the suction chamber 100 its suction function.

[0036] Specifically, the suction chamber 100 has a suction nozzle 110 at its top and a pipe connector 120 at its bottom. Most importantly, a partition plate 130 is installed inside the suction chamber 100. This partition plate 130 divides a portion of the suction chamber 100 into two chambers. However, the partition plate 130 does not extend from the top to the bottom of the suction chamber 100's inner cavity; rather, it is suspended at a certain position in the middle of the suction chamber 100's axial direction. The suction nozzle 110 of the suction chamber 100 can also be fitted with a replaceable mouthpiece 140. The mouthpiece 140 is detachably connected to the suction nozzle 110 on the top of the suction chamber 100. In some preferred embodiments, the mouthpiece 140 is also a component, which may include at least three parts: a first kit 141, a second kit 142, and a third kit 143. The three parts can be made of different materials. The outermost third kit 143 can be made of inexpensive but hygienic plastic material, which facilitates the disassembly and replacement of the mouthpiece 140, ensures that the mouthpiece 140 has good sealing performance, and is also relatively hygienic and safe.

[0037] The suction chamber support 200 has a hollow structure and extends from the outside of the suction chamber 100 through the tube connector 120 into the inner cavity of the suction chamber 100. The top of the suction chamber support 200 is provided with an air intake 210 communicating with the hollow structure. The suction chamber support 200 is essentially a tube that extends into the inner cavity of the suction chamber 100. The air intake 210 at the top of the suction chamber support 200 allows air in the inner cavity of the suction chamber 100 to enter the suction chamber support 200 through the air intake 210, and then be sucked away by the main unit 10 connected to the suction chamber support 200, forming a negative pressure in the suction chamber 100. Then, the nasal fluid is aspirated through the suction nozzle 110.

[0038] The suction chamber assembly 30 provided by this utility model has a partition plate 130 that separates the suction port 110 of the suction chamber 100 from the air intake port 210. After separation, two relatively independent channels are formed. The suction port connected to the suction port 110 can aspirate nasal fluid. After the nasal fluid enters the inner cavity of the suction chamber 100, it is isolated by the partition plate 130 and will not easily enter the air intake port 210. Instead, it remains temporarily in the suction chamber 100 and accumulates at the bottom of the inner cavity of the suction chamber 100 under the action of gravity. Since the suction chamber support 200 extends into the inner cavity of the suction chamber 100, and the air intake port 210 is in the middle of the suction chamber 100, it is far away from the accumulated fluid at the bottom of the inner cavity and will not enter the air intake port 210.

[0039] The suction chamber assembly 30 provided by this utility model has a relatively simple structure, consisting only of a suction chamber 100 and a suction chamber support 200 extending into the suction chamber 100. The suction port on the suction chamber 100 is separated from the air intake port 210 on the suction chamber support 200 by the partition plate 130 inside the suction chamber 100. This can separate the liquid entry channel from the gas suction channel, effectively preventing nasal fluid from easily entering the suction chamber support 200, and thus preventing nasal fluid from entering the suction tube 20 or even the main unit 10.

[0040] Optionally, in one embodiment of this utility model, such as Figure 2 As shown, the suction chamber 100 includes a detachably connected upper suction chamber 101 and a lower suction chamber 102. A suction nozzle 110 is located at the top of the upper suction chamber 101, a partition plate 130 is located inside the upper suction chamber 101, and a pipe connector 120 is located at the bottom of the lower suction chamber 102. The detachable, modular design of the upper and lower suction chambers 101 and 102 facilitates cleaning of the suction chamber 100, allowing for the removal of nasal secretions accumulated in the lower suction chamber 102 and making reuse more convenient. Specifically, a sealing ring 103 is provided between the upper and lower suction chambers 101 and 102 to ensure the suction chamber 100 is airtight. The detachable connection structure can employ a mating threaded structure. The partition plate 130 is integrally formed with the upper suction chamber 101.

[0041] Optionally, in another embodiment of this utility model, the suction nozzle 110 is inclinedly disposed on the suction chamber 100. The inclined placement of the suction nozzle 110 facilitates the operator's gripping and operation of the suction chamber 100, and also ensures that the bottom of the suction chamber 100 is in the lowest possible position, preventing nasal discharge accumulated at the bottom of the suction chamber 100 from flowing back into the inhalation port 210. In some specific implementations, such as... Figure 2 and Figure 3 As shown, the suction nozzle 110 is disposed on one side of the suction chamber 100. By disposing of the suction nozzle 110 on one side of the axial direction of the suction chamber 100, it is not necessary to tilt the suction nozzle 110; instead, the suction nozzle 110 can be directly disposed in an inclined position.

[0042] Optionally, in another embodiment of this utility model, such as Figure 3 As shown, the chamber with the suction port on one side of the partition plate 130 is smaller than the chamber with the air intake port 210 on the other side. The two chambers separated by the partition plate 130 have different volumes, with the side with the suction port having a smaller volume than the side with the air intake port 210. On the side with the smaller space, the gas volume change is greater, resulting in a stronger suction at the suction port. This allows the nozzle 110 to have a sufficiently strong suction. The structural design of this embodiment amplifies the suction of the nozzle 110 to a certain extent.

[0043] Optionally, in another embodiment of this utility model, such as Figures 2-4As shown, a transverse partition 220 is also provided on the suction chamber support 200, which is located between the inhalation port 210 and the tube connector 120; the inhalation port 210 is arranged radially along the suction chamber support 200. Although the partition plate 130 and the position of the suction chamber support 200 in the suction chamber 100 are sufficient to ensure that the nasal fluid accumulated in the suction chamber 100 will not easily enter the inhalation port 210, the transverse partition 220 is provided on the suction chamber support 200 to further isolate the inhalation port 210 from the bottom of the suction chamber 100, i.e., the tube connector 120, which can further ensure that the possibility of the nasal fluid accumulated in the suction chamber 100 entering the inhalation port 210 is even lower.

[0044] In conjunction with the foregoing embodiments, in one specific implementation, such as Figure 3 As shown, the radial edge of the partition 220 is spaced from the partition plate 130. This arrangement ensures that the structure of the partition 220 is relatively simple, without having to make the coverage area of ​​the partition 220 too large, which would consume more production materials. It also avoids contact with the partition plate 130 and mutual interference, thereby reducing the growth and development of microorganisms in the gaps between the contacting materials to a certain extent, ensuring safety and hygiene, and facilitating cleaning.

[0045] A second aspect of this utility model also provides a nasal aspirator, such as... Figure 5 and Figure 6 As shown, it includes a main unit 10, a suction tube 20, and a suction chamber assembly 30 as described in any of the first aspects of the present invention; one end of the suction tube 20 is connected to the main unit 10, and the other end is detachably connected to the suction chamber bracket 200.

[0046] In another embodiment of the second aspect, such as Figure 6 As shown, the main unit 10 includes a control circuit board 900, control buttons 300, a display screen 400, and a music module 500 connected to the control circuit board 900. The main unit 10 also has a sound outlet on its casing. The music module 500 is beneficial for the use of the nasal aspirator in infant care, as it can attract the infant's attention, distract them from anxiety, and ensure a smoother care process.

[0047] In conjunction with the foregoing embodiments, in one specific implementation, such as Figure 6As shown, the main unit 10 also includes an air pump 600 and a secondary battery 700. A charging interface 800 is also provided on the casing of the main unit 10, which is electrically connected to the secondary battery 700. The charging interface 800 is first connected to the control circuit board 900, and then to the secondary battery 700, allowing the secondary battery 700 to be charged. Correspondingly, the control circuit board 900 also has a charging circuit. The secondary battery 700 supplies power to the air pump 600. The control buttons 300, through operation of the control circuit board 900, control the operation of the display screen 400, the music module 500, and the air pump 600.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
