Nasal suction device

[0001] The present invention relates to a nasal suction device.

[0002] The acceleration of industrialization and urbanization, population growth, and transportation advancements have fostered active human interaction, but at the same time, have rapidly accelerated the spread of various diseases. Due to the impact of environmental pollution, diverse health problems, such as chronic rhinitis, allergic rhinitis, and viral diseases like the common cold, are occurring frequently in modern society.

[0003] For example, catching rhinitis or a cold causes a runny nose and nasal congestion, making breathing difficult; it can also be accompanied by headaches and decreased attention span, potentially leading to severe stress. While adults can blow their noses to clear the mucus themselves, infants, people with physical disabilities, or patients require assistance from others. If the mucus is not properly removed, it is highly likely to lead to more serious illnesses.

[0004] To solve these problems, devices capable of conveniently suctioning and removing nasal mucus or bodily fluids have been developed and are in use. Generally, such aspirators consist of a main body equipped with an internal pump and a suction device connected to the main body via a suction tube that comes into contact with the nostrils to suction out the mucus.

[0005] However, existing devices have a problem in that increasing suction power leads to increased noise and vibration, causing inconvenience to users, while reducing noise and vibration weakens suction power, resulting in reduced effectiveness.

[0006] The technology forming the background of the present invention is disclosed in Korean Registered Patent Publication No. 10-2197188.

[0007] The present invention aims to solve the problems of the aforementioned conventional technology by providing a nasal suction device that can solve the problem where increasing the suction power causes increased noise and vibration, causing inconvenience to the user, and reducing the noise and vibration weakens the suction power, resulting in reduced effectiveness.

[0008] However, the technical problems that the embodiments of the present invention aim to solve are not limited to the technical problems described above, and other technical problems may exist.

[0009] As a technical means for achieving the above-mentioned technical problem, a nasal discharge suction device according to one embodiment of the present invention comprises: a main body part including a case having a connector formed on its outer surface and a pair of driving motors provided inside the case for generating vacuum pressure; and a suction part including a suction tube connected to the connector and an insertion part inserted into the user's nose, wherein at least some of the pair of driving motors are driven simultaneously to generate vacuum pressure, and the vacuum pressure generated by the pair of driving motors is provided through the suction tube, allowing the suction part to suction the user's nasal discharge.

[0010] In addition, the main body may further include a control unit that is provided on the outer surface of the case and controls the amount of air sucked in through the vacuum pressure.

[0011] Additionally, the main body may further include a battery that is provided inside the case and supplies power to the pair of driving motors; and a charging terminal provided to supply charging power to the battery.

[0012] In addition, the main body may further include a cover unit configured to close the connector when the nasal suction device is not in use.

[0013] The main body may further include a gripping groove formed on the rear surface of the case so that the user can grip the main body.

[0014] In addition, the main body may further include a display unit capable of checking at least one of the remaining amount of the battery, the intensity of suction through the vacuum pressure, and the operating status.

[0015] In addition, the suction part may be equipped with a backflow prevention valve to prevent at least some of the user's nasal mucus from flowing back.

[0016] In addition, the insert may be provided in multiple sizes and shapes and may be provided so as to be replaceable to fit the user's nose structure.

[0017] The means for solving the problem described above are merely exemplary and should not be interpreted as intended to limit the present invention. In addition to the exemplary embodiments described above, additional embodiments may exist in the drawings and the detailed description of the invention.

[0018] According to the solution to the problem of the present invention described above, by generating vacuum pressure through a pair of drive motors, strong suction force can be provided, and at the same time, noise and vibration can be reduced.

[0019] However, the effects obtainable from this invention are not limited to those described above, and other effects may exist.

[0029] The present invention relates to a nasal suction device.

[0030] Hereinafter, a nasal suction device according to one embodiment of the present invention (hereinafter referred to as 'the device (100)') will be described.

[0031] FIG. 1 is a drawing for explaining a nasal discharge suction device according to one embodiment of the present invention.

[0032] FIG. 2 is a drawing for explaining the internal space of the main body part in one embodiment of the present invention.

[0033] Specifically, FIG. 2(a) is a drawing showing the case (111) of the main body (110) in FIG. 1 with a part (upper part) and the gripping groove (117) to be described later removed, and FIG. 2(b) is a drawing showing the case (111) of the main body (110) in FIG. 1 with a part (upper part) removed.

[0034] Referring to FIG. 1, the device (100) may include a main body part (110) and a suction part (120).

[0035] Specifically, referring to (a) of FIGS. 1 and FIGS. 2, the main body (110) may include a case (111) having a connector (111a) formed on its outer surface, and a pair of drive motors (112) provided inside the case (111) to generate vacuum pressure.

[0036] For example, as shown in FIG. 1, the case (111) may be provided to form the outer shape of the main body (110). At this time, the shape of the case (111) is not limited to that shown in FIG. 1.

[0037] Additionally, referring to FIG. 2(a), the case (111) may be provided with an internal space large enough to accommodate a pair of drive motors (112) inside.

[0038] In addition, it is desirable that the internal space be set to accommodate the battery (114), nasal mucus storage container, and communication module described later.

[0039] Additionally, referring to FIG. 2, a pair of drive motors (112) can generate vacuum pressure inside the case (111). At this time, the generated vacuum pressure can be transmitted to a connector (111a) through a pipe (not shown).

[0040] For example, a vacuum pump that generates vacuum pressure may be provided in the internal space of the case (111), and a pair of drive motors (112) may drive the vacuum pump to generate vacuum pressure.

[0041] At this time, a pair of drive motors (112) can be driven at least partially simultaneously to generate vacuum pressure.

[0042] For example, if the required vacuum pressure intensity (suction intensity) is low, only one of the two drive motors (112) can be driven to generate vacuum pressure. As another example, if the required vacuum pressure intensity (suction intensity) is high, both of the two drive motors (112) can be driven simultaneously to generate a vacuum pressure stronger than that generated by one of the drive motors (112).

[0043] Additionally, referring to FIG. 1, the main body (110) may include a control unit (113) that is provided on the outer surface of the case (111) and controls the amount of air sucked in through vacuum pressure.

[0044] At this time, the control unit (113) may be provided in a knob shape as shown in FIG. 1, but is not limited thereto. For example, the control unit (113) may be provided in various forms such as a jog dial, a button, a touchpad, and a joystick.

[0045] Specifically, the amount of air sucked in through vacuum pressure is set through the control unit (113), and accordingly, a pair of drive motors (112) are driven to generate vacuum pressure.

[0046] Additionally, the main body (110) may include a communication module capable of communicating with a user device.

[0047] For example, the communication module may be installed inside the case (111) and may be configured to communicate with the user's user device.

[0048] Here, the user terminal can be any type of wireless communication device, such as a smartphone, smartpad, tablet PC, etc., and a PCS (Personal Communication System), GSM (Global System for Mobile communication), PDC (Personal Digital Cellular), PHS (Personal Handyphone System), PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), or Wibro (Wireless Broadband Internet) terminal.

[0049] In addition, communication modules and user terminals can communicate with each other through a network. A network refers to a connection structure that enables the exchange of information between each node, such as terminals and servers. Examples of such networks include, but are not limited to, 3GPP (3rd Generation Partnership Project) networks, LTE (Long Term Evolution) networks, 5G networks, WIMAX (World Interoperability for Microwave Access) networks, the Internet, LAN (Local Area Network), Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal Area Network), Wi-Fi networks, Bluetooth networks, satellite broadcasting networks, analog broadcasting networks, and DMB (Digital Multimedia Broadcasting) networks.

[0050] Additionally, the main body (110) may include a control unit installed inside a case (111) and controlling the operation of a pair of drive motors (112).

[0051] For example, the control unit can control the operation of a pair of drive motors (112) so that air corresponding to the amount of air to be sucked in through the control unit (113) can be sucked in through the suction unit (120) to suck in the user's nasal mucus.

[0052] In addition, the control unit can control a pair of drive motors (112) based on communication between the user device and the communication module.

[0053] For example, the user inputs user information (e.g., user's age, duration of runny nose, etc.) through a user device, and the communication module can receive the user information. At this time, the control unit can determine the amount of air intake based on the user information and control a pair of drive motors (112).

[0054] In addition, the control unit can increase the output of the drive motor (112) to provide strong suction power when the amount of nasal mucus sucked in through the suction unit (120) described later is large.

[0055] In addition, the control unit can stop the operation of the drive motor (112) when no more nasal mucus is sucked in through the suction unit (120) described later.

[0056] Additionally, the main body (110) may be equipped with a tilt detection sensor that detects when the main body (110) is tilted. At this time, the control unit can control the drive motor (112) to stop driving when the main body (110) is in a tilted state through the tilt detection sensor.

[0057] Additionally, the user can set the usage time of the device (100) through a user device, and the device (100) can receive the usage time set by the user through a communication module and control the driving time of a pair of driving motors (112) through a control unit.

[0058] Additionally, when a user inputs a stop signal to stop the operation of the device (100) through a user device, the communication module receives the stop signal, and the control unit can stop the operation of a pair of drive motors (112) according to the stop signal. Accordingly, the user can remotely set the start and stop of operation of the device (100).

[0059] FIG. 3 is a drawing for explaining a cover unit in one embodiment of the present invention.

[0060] Additionally, referring to FIG. 3, the main body (110) may include a cover unit (116) provided to close the connector (111a) when the device (100) is not in use.

[0061] For example, the surface attached to the main body (110) of the cover unit (116) and the surface on which the connector (111a) of the case (111) is formed are provided with a magnetic material so that the cover unit (116) can be attached to the main body (110) without a separate device and the connector (111a) can be closed.

[0062] However, the method of attaching (combining) the cover unit (116) is not limited to this and can be attached through various methods. Since this is obvious to a person skilled in the art, a more detailed explanation will be omitted.

[0063] Through this, the device (100) can prevent foreign substances from entering through the connector (111a) when not in use, thereby preventing damage to the device.

[0064] FIG. 4 is a drawing for explaining a charging terminal in one embodiment of the present invention.

[0065] Additionally, referring to FIGS. 2 and FIGS. 4, the main body (110) may further include a battery (114) that supplies power to a pair of drive motors (112) and a charging terminal (115) that supplies charging power to the battery (114).

[0066] Specifically, referring to FIG. 2, the battery (114) may be positioned in the internal space of the case (111) to supply power to a pair of drive motors (112).

[0067] In addition, the battery (114) may be provided to supply power to the display unit and communication module to be described later.

[0068] Additionally, referring to FIGS. 2 and 4, the battery (114) may be configured to be charged through a charging terminal (115) to supply power to a pair of drive motors (112), a display unit and a communication module to be described later.

[0069] Accordingly, the device (100) has a built-in battery (114) so ​​that the main body can be operated without an external electrical connection, and thus can be used even in places where it is difficult to supply power.

[0070] Additionally, the main body (110) may include a nasal mucus storage container provided inside the case (111).

[0071] At this time, the nasal mucus storage container may be provided so that nasal mucus sucked in through the suction part (120) described later can be stored.

[0072] Additionally, referring to FIG. 2(b) and FIG. 4, the main body (110) may include a gripping groove (117) formed on the rear surface of the case (111) so that a user can grip the main body (110).

[0073] Specifically, referring to FIG. 2(b) and FIG. 4, the gripping groove (117) is provided to be recessed from the rear of the case (111) toward the internal space, so that a user can put their hand into the gripping groove (117) recessed toward the internal space and grip the main body (110). However, the gripping groove (117) may be formed on the rear of the case (111) as shown in FIG. 2 and FIG. 4, but is not limited thereto and may be formed at various locations that can be recessed toward the internal space.

[0074] Additionally, referring to FIG. 2(b) and FIG. 4, the depth and width of the gripping groove (117) can be set so that a user can insert their hand and grip the device (100).

[0075] Additionally, the gripping groove (117) may be formed to tilt upward toward the internal space to prevent the main body (110) from slipping out of the user's hand when the user puts their hand in and lifts it, as shown in (b) of FIG. 2.

[0076] FIG. 5 is a drawing for explaining a mounting protrusion in one embodiment of the present invention.

[0077] Additionally, referring to FIG. 5, the lower surface of the case (111) can be provided flat so that the main body (110) can be placed at a usage location (floor, desk, etc.).

[0078] At this time, as illustrated in FIG. 5, an anti-slip member (119) may be attached to the lower surface of the case (111) to at least partially prevent the main body (110) from sliding or falling over when placed in a usage location (floor, desk, etc.). Specifically, the anti-slip member (119) may be provided with various materials capable of increasing friction with the surface corresponding to the usage location. Since this is obvious to a person skilled in the art, a more detailed explanation will be omitted.

[0079] Additionally, referring to FIG. 5, the main body (110) may include a mounting protrusion (118) formed on the case (111). For example, as shown in FIG. 5, the protrusion may be formed along the circumferential direction of a surface having curvature on the lower side of the case (111). Accordingly, the device (100) can be used stably during use.

[0080] However, the number of mounting protrusions (118) is not limited to that shown in FIG. 5 and can be set to a number that enables stable placement when the main body (110) is placed on the floor surface, and the position of the mounting protrusions (118) is not limited to that shown in FIG. 5 and can be set to a position that enables stable placement when the main body (110) is placed on the floor surface.

[0081] Additionally, the main body (110) may include a display unit capable of checking at least one of the remaining amount of the battery (114), the intensity of suction through vacuum pressure, and the operating status.

[0082] For example, a display unit (not shown) is mounted on a case (111) and can provide the user with the remaining amount of the battery (114), the intensity of suction through vacuum pressure, and the operating status.

[0083] In addition, the device (100) can provide status information and operation information of the device (100), such as the remaining amount of the battery (114), the intensity of suction through the current vacuum pressure, and the operating status, to the user through a user device via a communication module.

[0084] In addition, the aforementioned nasal mucus storage container may be equipped with a sensor module capable of recognizing the amount of nasal mucus stored in the nasal mucus storage container.

[0085] Specifically, the sensor module mounted on the nasal mucus storage container may be equipped to recognize the amount of nasal mucus stored in the nasal mucus storage container.

[0086] In addition, the display unit can provide the user with information on how much of the nasal mucus is stored in the volume of the nasal mucus storage container through a sensor module mounted on the nasal mucus storage container.

[0087] In addition, the communication module can provide the user with information via the user device regarding how much nasal mucus is stored in the volume of the nasal mucus storage container through a sensor module mounted on the nasal mucus storage container. Additionally, if more than a preset amount (volume) of nasal mucus is stored in the nasal mucus storage container, the user can provide a notification via the user device that the nasal mucus must be emptied from the nasal mucus storage container.

[0088] Additionally, referring to FIGS. 1 and 2, the suction part (120) may include a suction tube (121) connected to a connector (111a) and an insertion part (122) inserted into the user's nose.

[0089] Specifically, the suction pipe (121) may be provided on one side of the suction part (120) as shown in FIG. 1 and FIG. 2. Additionally, although not shown in FIG. 2, the suction pipe (121) may be provided in an extended manner and directly connected to the connector (111a).

[0090] As another example, the suction tube (121) and the connector (111a) can be indirectly connected through a tubular member (not shown).

[0091] In other words, the connection between the suction part (120) and the connector (111a) can mean both the suction part (120) being extended and directly connected to the connector (111a) and the suction pipe (121) and the connector (111a) being indirectly connected through a tubular member.

[0092] In addition, the suction part (120) can suck up the user's nasal mucus by receiving vacuum pressure generated by a pair of drive motors (112) through the suction tube (121).

[0093] For example, a vacuum pump that generates vacuum pressure may be provided in the internal space of the case (111), and a pair of drive motors (112) drive the vacuum pump to generate vacuum pressure, and the generated vacuum pressure is transmitted to the suction tube (121) through the connector (111a), so that the insert part (122) inserted into the user's nose receives the vacuum pressure and can suck the user's nasal mucus.

[0094] At this time, the inhaled nasal mucus can be transferred to a nasal mucus storage container installed (mounted) inside the case (111) through the connection of the suction tube (121) and the connector (111a).

[0095] Additionally, the suction part (120) may be equipped with a backflow prevention valve to prevent at least some of the user's nasal discharge from flowing back.

[0096] For example, a backflow prevention valve may be provided at the location where the insertion part (122) and the suction tube (121) are connected within the internal space of the suction part (120) to prevent nasal mucus from flowing back into the user's nose.

[0097] As another example, a backflow prevention valve may be provided at the stage where the suction pipe (121) is extended and connected to the connector (111a) to prevent nasal mucus from flowing back into the suction part (120). However, the installation location of the backflow prevention valve is not limited to this.

[0098] Additionally, the insertion part (122) is provided in a plurality of sizes and shapes and can be provided so as to be replaceable to fit the user's nose structure.

[0099] For example, the insert (122) can be provided in various sizes and shapes ranging from infants to adults. Additionally, the insert (122) can be provided to be detachable so that it can be replaced with an insert (122) that fits the user's nose structure (size and shape of the nostrils).

[0100] Additionally, the suction part (120) may be equipped with a sensor that prevents damage to the inner wall of the user's nose when the user's nasal mucus is sucked in through vacuum pressure by attaching the insertion part (122) to the user's nose.

[0101] For example, the sensor may be equipped as a distance sensing sensor to detect the distance between the end of the insertion part (122) (the part where nasal mucus is sucked in through vacuum pressure) and the inner wall of the user's nose.

[0102] At this time, if the end of the insertion part (122) (the part where nasal mucus is sucked in through vacuum pressure) touches the inner wall of the user's nose or gets closer than a preset distance, the control unit can stop the operation of the drive motor (112) to prevent damage to the inner wall of the user's nose.

[0103] As another example, the suction part (120) may be equipped with an angle sensing sensor capable of detecting the angle at which the insertion part (122) is inserted into the user's nose when the insertion part (122) is attached to the user's nose and the user's nasal mucus is sucked in through vacuum pressure.

[0104] At this time, if the insertion part (122) is inserted into the user's nose outside the preset angle range by the angle detection sensor, or if it is inserted into the user's nose within the preset angle range and then the user's movement causes it to move outside the preset angle range, the control unit can stop the operation of the drive motor (112) to prevent damage to the inner wall of the user's nose.

[0105] At this time, the preset angle range can be set to an angle range in which the inner wall of the user's nose is not damaged by vacuum pressure. For example, the end of the insertion part (122) (the part where nasal mucus is sucked in through vacuum pressure) can be set to an angle range in which it does not touch the inner surface of the user's nose.

[0106] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without altering the technical concept or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and components described as distributed may likewise be implemented in a combined form.

[0107] The scope of the present invention is defined by the claims set forth below rather than by the detailed description above, and all modifications or variations derived from the meaning and scope of the claims and the concept of equivalents thereof should be interpreted as being included within the scope of the present invention.
