Description

nasal aspirator

Technical Field

The present disclosure relates to nasal aspirator systems.

Background Art

Nasal aspirator systems are commonly used for nasal cleaning of humans or any other animals. For example, babies lack the ability to clean their own nostrils efficiently, so that the nostrils are blocked for a long time, which impairs breathing, eating, breastfeeding and mood. Due to the frequency of runny nose or nasal congestion, parents can buy nasal aspirators of various types and functions. Common nasal aspirators are rubber bulbs that include a front end that can be inserted into the baby's nostrils. Squeezing the bulb allows air to pass from the ball through the front end. Releasing the bulb creates a low (i.e. negative) pressure area in the ball, allowing air (and possible mucus) to enter the ball through the front end, and due to elasticity, when the ball is re-inflated, it will cause a balance of pressure (returning to a neutral state). This balancing process creates suction from the front end, and relatively speaking, mucus or nasal secretions are sucked out from the nostrils (assuming that the front end has been placed in the nostrils when released).

Summary of the Invention

Systems and methods for a nasal aspirator are described. In some implementations, an aspirator device is provided, comprising: a bulbous aspirator portion comprising a bulb, a first collar, and a front end, wherein the bulb comprises an upper portion configured to receive one end of the first collar and a lower portion configured to receive a stopper in a first configuration and a second collar associated with a suction tube in a second, different configuration, wherein the front end is configured for insertion into a passageway and is tapered and angled in shape for ease of insertion and conformity to a corresponding cavity; a stopper configured to be removably connected to the lower portion of the bulb in the first configuration; and a suction tube comprising a second collar, a tube portion, and an adapter, wherein the second collar is disposed at a first end of the suction tube and adapted to couple to the lower portion of the bulb, wherein the adapter is coupled to a second end of the suction tube and configured to fit within a person's mouth to enable suction to be applied at the adapter, such that when the tube portion is coupled to the bulbous aspirator in the second, different configuration, suction can be applied through the suction tube into the bulbous aspirator.

Specific embodiments of the subject matter described in this specification can be implemented to achieve more than one of the following advantages. The described nasal aspirator system provides precise, fine-tuned control over suction through the nasal aspirator system. The nasal aspirator system can include a front end that inserts into the infant's nostrils, while the other end inserts into the parent's mouth. Parents can precisely control the amount of suction by adjusting their own lungs and the depth and rate of their breathing. Because parents can precisely control suction and instantly stop (as needed), the nasal aspirator system is safer than previous aspirator systems. One or more filters can be included in the nasal aspirator system to block any mucus or secretions (or any other particulate matter) aspirated from the nostrils. When used in suction mode, the nasal aspirator system also utilizes a one-way valve to substantially block air from returning to the front end, eliminating the risk of air being accidentally blown back into the nostrils through the nasal aspirator system. When configured with a one-way valve, the device can also be used to aspirate foreign matter (such as that accidentally placed in the nostrils by a child). Examples of foreign bodies include toys or toy parts (such as small marbles) or food products containing nuts, seeds, fruits, or other small items that could become lodged in the nostril.

The details of one or more embodiments of the subject matter of this specification are set forth in the following drawings and the description. Other features, aspects, and advantages of the subject matter will become apparent from the description, drawings, and claims.

DETAILED DESCRIPTION

1 , there is shown an example of an aspirator device 100. The aspirator device 100 includes a bulb-shaped aspirator 10 coupled to a suction tube 20.

The bulb suction device 10 includes a bulb 12 configured to receive a removable first collar 14 at an upper portion 16. The first collar 14 is further configured for removable connection to a front end 30 that can be inserted into an orifice, such as an adult or infant's nostril. The bulb 12 includes a lower portion 17 that is further configured to receive a stopper 40 in a first configuration and a suction tube 20 in a second configuration.

The suction tube 20 includes a tube portion 22 for the flow of gas or fluid or a combination of these, with a second shaft collar 18 arranged at one end of the tube portion 22. An adapter 24 can be connected to the opposite end of the tube portion 22 and is configured to fit into a person's mouth. The adapter 24 allows suction to be created by the person, which causes air to enter the mouth through the adapter 24 in a first direction. Additionally, in some embodiments, the adapter 24 is configured to substantially prevent air from being pushed into the adapter 24, substantially blocking the flow of air in the opposite (e.g., second, different) direction out of the mouth and back into the tube portion 22. In some embodiments, a one-way valve may be included in the adapter 24 or arranged at another location in the ball aspirator 10.

In a first configuration, such as one in which the stopper 40 is inserted into the bulb 12 at the lower portion 17, a person can deform the bulb 12, such as by squeezing the bulb 12, to expel air from the interior of the bulb 12 through the front end 30. The front end 30 can then be inserted into an orifice, such as an infant's nostril, and the deformed bulb 12 can be released, causing air and particulate matter, such as mucus, to be drawn into the bulb 12 through the front end 30.

In the second configuration, in which the suction tube 20 is mounted to the bulb 10, a person can create suction and control the suction through the adapter 24 by adjusting the pressure differential between atmospheric pressure (existing at the front end of the bulb) and the pressure in the space associated with the person's body, such as by creating a negative pressure to initiate the suctioning action, for example by activating the muscles of the mouth and diaphragm to rapidly increase the volume of air inside the person's body. The pressure differential will then force air through the front end 30, the bulb 12, the suction tube 20, and out of the adapter 24 into the person. Because the person can control the suction and thus the airflow through the aspirator device 100, the person can insert the front end 30 into the nostrils of an infant and have good control over the suction induced in the delicate nostrils.

FIG2 is a schematic diagram of the bulb suction device 10 in a first configuration. As described above, the bulb suction device 10 includes a bulb 12, a first collar 14, and a front end 30. The first configuration of the bulb suction device 10 includes the bulb suction device 10 having a stopper 40 inserted into the lower portion 17 of the bulb 12. When the stopper 40 is located at the lower portion of the bulb, the stopper 40 can allow a pressure differential to be created by squeezing and releasing the bulb 12 (e.g., by preventing air from flowing out of the lower portion 17).

In some implementations, the sphere 12 included in the sphere suction device 10 is generally made of a deformable material, such as a human hand capable of deforming the sphere 12. In some implementations, the sphere 12 can be made of a transparent plastic, such as a high-grade silicone plastic, that can retain air, fluids, and particulate matter that pass through or remain within the sphere 12. The transparent plastic that defines the shape of the sphere 12 can be approximately 2 mm, 2.5 mm, or 3 mm thick, and the interior of the sphere 12 can be hollow to retain air, fluids, or solids, such as air or mucus.

In some implementations, the bulb 12 is generally symmetrical about a first axis 1 and can be approximately 50 mm, 55 mm, or 60 mm along the first axis 1. Additionally, in some implementations, a midsection of the bulb 12 can be approximately 40 mm, 48 mm, or 54 mm along an orthogonal second axis 2. In some implementations, the bulb 12 tapers down along the second axis 2 as the body extends further from the midsection along the first axis 1, reaching distal ends of the bulb, such as the upper portion 16 and lower portion 17 described below.

Spheroid 12 can be roughly described as an ellipsoid, such as a flattened ellipsoid, having an upper portion 16 at one end of spheroid 12 and a lower portion 17 at the opposite end of spheroid 12. Lower portion 17 and upper portion 16 are hollow cylinders extending from the ellipsoid with corresponding openings at the ends of spheroid 12.

The absolute value of the derivative of the arc length 4 of the second axis 2 of the spherical body 12 with respect to the first axis 1 can be relatively constant from the lower portion 17 to the upper portion 16 of the spherical body 12. The derivative of the arc length 4 can decrease, for example, at approximately 5 mm, 7 mm, or 9 mm from the opening of the upper portion 16 and the opening of the lower portion. This decreasing derivative creates a substantially flat cylinder that fits on both sides of the ellipsoid of the spherical body 12. The cylinder of the upper portion 16 allows for connection to the first collar 14 and allows a person to place their thumb or finger on the cylinder when in use in the first configuration.

As shown in FIG2 , in a first configuration, the barrel of the lower portion 17 allows for connection to the stopper 30. The lower portion 17 includes a first end, such as an open neck region 5, and a second, opposite end, such as the neck region 5, adjacent to the ellipsoid of the spheroid 12. The neck 5 can define the barrel of the lower portion 17 and can have a specific distance, such as approximately 4 mm, 8 mm, or 12 mm, along the first axis 1. In some implementations, the neck region can be recessed so that the spheroid 12 is substantially flat at the bottom of the lower portion.

The stopper 40 includes a cap having a radius similar to or greater than that of the opening of the ball 12 and an elongated portion extending from the cap. The elongated portion of the stopper 40 is intended to be inserted through the opening of the ball 12 and positioned (retained) inside the neck 5. The radius of the elongated portion is selected so as to apply pressure to the neck 5, such as when the ball 12 is deformed when used in the first configuration, so that the elongated portion creates a seal that blocks air flow through the opening.

The neck region 5 includes a peripheral recess that can hold a ring 42 mounted to the stopper 40. As shown in FIG2 , the ring 42 mounted to the stopper 40 can be hooked into the peripheral recess, keeping the stopper 40 connected to the ball 12 when the stopper 40 is inserted or not inserted into the ball 12. Other features for maintaining the stopper when in use or not in use are possible.

The outer peripheral recess creates an inner peripheral ridge in the neck 5. In some implementations, the stopper 40 can include a corresponding circumferential recess on the elongated portion that can receive the inner peripheral ridge of the neck 5. In this way, the stopper 40 can be locked to the neck 5, which helps create a seal to block air flow through the opening of the ball 12.

Ball 12 has an opening at upper portion 16 configured to receive first collar 14. Upper portion 16 includes an inner peripheral ridge configured to receive a ridge included on the exterior of first collar 14 (eg, a first ridge separate from a second ridge of a different size).

In some implementations, the first collar 14 can be made of a hard plastic, such as polypropylene, and include a hollow passageway for the flow of air, fluid, and particulate matter. The first collar 14 has a ridge that opposes an inner ridge in the upper portion 16, for example, to lock the ridge of the first collar 14 to the inner ridge of the upper portion 16. In this manner, a user can insert the first collar 14 into the upper portion 16 to install the first collar 4.

In some implementations, when the first collar 14 is inserted into the ball 12, a portion of the first collar 14 remains outside the ball 12. This portion of the first collar 14 is configured to be inserted into the distal end of the nose 30, and the first collar 14 is used to connect the ball 12 to the nose 14 via various connections.

The distal end of the front end 30 includes one or more inner ridges that can be connected to a portion of the first collar 14 (e.g., the portion that remains outside the spheroid 12). The ridges of the front end 30 can be formed so that after the front end 30 is connected to the first collar 14, the front end 30 will not come loose when a person pulls on the front end 30 without sufficient force. The detachable portions of the first collar 14, the front end 30, and the spheroid 12 allow the components to be easily cleaned and/or sterilized. Similarly, using a transparent material for the spheroid 12 and the front end 30 allows visual inspection of the aspirator device 100 once assembled.

The nose 30 is configured with an inner hollow nozzle having an opening 32 at the proximal end through which, when suction is applied by, for example, deformation of the body in the first configuration or by a person in the second configuration, air, fluid, and particulate matter can pass, through the opening 32, through the hollow passageway of the first collar 14, and into the hollow bulb 12. The opening 32 of the nose 30 is angled to facilitate insertion into a cavity (e.g., the nasal cavity of an adult, child, or infant). This angle can be determined, for example, from an examination of the shape of an average infant nasal cavity. In addition, the radius of the inner hollow nozzle of the nose 30 can be of a sufficiently small size (e.g., approximately 2 mm, 4 mm, or 5 mm) to allow the nose 30 to easily enter a person's nostril.

Additionally, the front end 30 may be made of a deformable material, such as in the form of silicone rubber, for comfort when inserted into the nostrils of a person, such as an infant.

3A is a schematic diagram of the outer ridge 15 of the first collar 14 and the connection of the nose 30 to the first collar 14 and the first collar 14 to the ball 12. The first collar 14 can be removably connected to the nose 30 by inserting the first collar 14 into the nose 30, and can be removably connected to the ball 12 by inserting the first collar 14 into the ball 12. Other connection methods are possible (press fit, sleeve, etc.).

Front end 30 includes internal ridges 33, illustrated in FIG3B , that are complementary to ridges 15 of removable first collar 14. Complementary ridges are ridges that have approximately opposite heights to different ridges, enabling the ridges to interlock. As shown, ridges 15 extend from, for example, a tapered barrel 19 that tapers toward the distal end of front end 30, illustrating the basic form of first collar 14. Ridges 15 have varying heights relative to tapered barrel 19, creating a seal when resting against complementary internal ridges 33 in front end 30. When first collar 14 is inserted into ball 12, first collar 14 is connected to front end 30 via one or more ridges 15 of first collar 14 extending from ball 12.

In implementations where the nose 30 is made of a deformable material, the tapered barrel 19 of the first collar 14 can have a sufficient radius to apply pressure upon insertion against the inner ridge 33 of the nose 30. In this manner, in addition to the corresponding complementary ridges of the nose 30 and the first collar 14, the first collar 14 can be held in place by pressure.

The ball 12 is capable of receiving the first collar 14 by inserting the first collar 14 into the upper portion 16 of the ball 12. The ball 12 includes an inner ridge, illustrated in FIG3B , that is capable of receiving the outer ridge 15 of the first collar 14. The radius of the upper portion 16 of the ball 12 can be a sufficiently small radius relative to the radius 15 of the tapered barrel 19 of the first collar 14 so that pressure is created between the ball 12 and the first collar 14 when inserted.

One or more outer ridges 15 of the first collar 14 are configured to be inserted into the ball 12, and one or more outer ridges 15 are configured to remain outside the ball 12 when the first collar 14 is inserted. To make this effective, the inner ridges of the ball 14 illustrated in FIG3B can be complementary to less than all of the outer ridges 15 of the first collar 14. In this way, when the first collar 14 is inserted, the outer ridges 15 that lack complementary inner ridges in the ball 12 will remain outside the ball 12.

As described above, the outer ridge 15 remaining on the exterior of the ball 12 is configured to be inserted into the nose 30. Although reference is made to a nose and ball having specific dimensions and configurations (such as so that the two separate pieces separate to enable cleaning of the interior of the ball), the separation point associated with the first collar can be anywhere on the ball as desired.

3B is a schematic diagram of the leading end 30 and the inner spine of the ball 12. As described above, the ball 12 is configured to receive the first collar 14, and the leading end 30 is configured to receive the first collar 14.

The front end 30 includes one or more internal ridges 33 , such as inner peripheral ridges, with each ridge receiving a connection with a complementary external ridge 15 of the first collar 14 .

The ball 12 includes one or more internal ridges 17 , such as inner peripheral ridges, with each ridge receiving a connection with a complementary external ridge 15 of the first collar 14 .

As shown in FIG3B , the first collar 14 includes two outer ridges 15 that can be inserted into the complementary inner ridges 17 of the bulb 12. The first collar 14 also includes a third outer ridge 15 that can be inserted into the complementary inner ridge 33 of the front end 30. In this manner, the first collar enables the bulb 12 to be connected to the front end 30. Thus, the bulb 12 is flush with the distal end of the front end 30, creating a continuous path on the outer surface of the bulb suction device 10 from the proximal end of the front end 30 to the opposite side of the bulb 12.

After the front end 30 is connected to the ball 12, a continuous path is created for the flow of air, fluid, and particulate matter, extending from the hollow nozzle 32 at the proximal end of the front end 30, through the first collar 14, and into the ball 12. The interlocking connections between the front end 30 and the first collar 14 and between the first collar 14 and the ball 12 create a seal that keeps the flow of air, fluid, and particulate material contained within the ball aspirator 10.

FIG4 is a schematic diagram of the bulb suction device 10 in a second configuration. As described above, the suction device 100 includes the bulb suction device 10 and the suction tube 20 configured to be coupled to the bulb 12 of the bulb suction device 10. In the second configuration, the bulb 12 of the bulb suction device 10 is coupled to the suction tube 20, allowing particulate matter, such as mucus in an infant's nose, to be drawn into the bulb 12 through the front end 30 by suction, such as that created by a person's mouth, applied to the adapter 24.

The second collar 18 is adapted to be removably inserted into the lower portion 17 of the ball 12 and is also adapted to be removably inserted into the tube portion 22 of the suction tube 20 .

Second collar 18 can be constructed from a rigid plastic, such as polypropylene, that can be inserted into lower portion 17 of ball 12. As described above, ball 12 can be constructed from a deformable material that can be stretched around second collar 18. Thus, second collar 18 can be inserted into lower portion 17 of ball 12 and held in place by pressure created between second collar 18 and ball 12. In some implementations, second collar 18 can be configured so that, upon insertion, a portion of second collar 18 extends outside ball 12. This portion of second collar 18 can then be inserted into tube 22, creating a connection between ball 12 and tube 22.

In some implementations, the second collar 18 includes a filter 25 to block particulate matter or fluid from being drawn into the tube portion 20 when a person applies suction to the adapter 24. The filter 25, for example, can block particulate matter larger than a certain size, where the material can be, for example, a layer of metal, plastic, or fiber material. The filter 25 can be selected to substantially block the flow of mucus and fluid while allowing air to pass from the front end 30 to the adapter 24.

In some implementations, the filter can be located anywhere along the airflow path created from the interior of the front end of the bulb to the adapter inserted into a person's mouth. For example, in some implementations, the filter 25 can be inserted into the lower portion 17 of the bulb 12. The filter 25 can have a sufficient radius so that when the second collar 18 is inserted, the filter 25 applies pressure to the lower portion 17 of the bulb 12. In some implementations, the filter 25 can be inserted into the tube 22 and have a sufficient radius so that when the second collar 18 is inserted, the filter 25 applies pressure to the tube 22.

In the configuration in which the filter 25 is included in the detachable second collar 18, the filter 25 can be removed by a person, for example, for cleaning or replacement. Other configurations can be easily removed as needed. In some implementations, the filter 25 is designed to be, for example, moved underwater and cleaned. In some embodiments, the filter 25 is a disposable filter, and a person can use a new filter 25 each time the aspirator device 10 is used.

In some embodiments, the second collar 18 includes a one-way filter 26 that can substantially inhibit the flow of air expelled by the person into the aspirator device 10 and, for example, allow the flow of air pushed into the person through the aspirator device, for example, by atmospheric pressure. The one-way filter 26 can be a check valve, such as a ball check valve, a diaphragm check valve, a swing check valve, or the like. In this way, a person can apply suction to the nostrils of a person, such as an infant, without having to worry about accidentally blowing air into the nostrils. In some embodiments, similar to the filter 25, the one-way filter 26 can be replaced by the person.

The tube 22 can be approximately 300mm, 350mm or 400mm long and can be created from a deformable material such as the same material as the bulb 12, plastic, rubber, and can be substantially transparent. In this way, a person can easily check the cleanliness of the tube.

As described above, the tube portion 22 receives a connection to the second collar 18 and also receives a connection to the adapter 24 that can be inserted into a person's mouth. In this way, the tube portion 22 acts as a bridge between the adapter 24, where a person can create suction, and the ball 12, where particulate matter aspirated through the front end 30 can be collected.

5 can include a one-way filter 26 in addition to the one-way filter 26 included in the second collar 18, or the adapter 24 can include the only one-way filter 26. Similarly, the adapter can include a filter 25 for blocking the flow of particulate matter such as mucus.

5 is a schematic diagram of an adapter 24 inserted into the tube portion 22. As shown, the adapter 24 includes a one-way filter 26 and a suction tip 27 adapted for a person's mouth. In some implementations, the adapter 24 can include a filter 25 together with or in addition to the one-way filter 26.

In some implementations, the adapter 24 can be made of a hard plastic, such as polypropylene, and can have a connector 28 of the adapter 24 inserted into the tubing 22. The radius of the connector 28 can be larger than the radius of the tubing 22 to create pressure between the connector 28 and the tubing 22 during insertion. Additionally, the length of the connector 28 can be approximately 5 mm, 8 mm, or 10 mm and can extend into the length of the tubing 22.

The connector 28 of the adapter 24 can extend from the one-way filter 26, for example, to allow the adapter 24 to be mounted to the tubing 22. In some implementations, the one-way filter 26 can be inserted into the tubing 22 together with the connector 28 and have a substantially similar radius as the connector 28. In some implementations, the one-way filter 26 can have a larger diameter and include a portion adapted to couple to the tubing 22.

The suction front end 27 is configured to allow air to pass through and into a person's mouth, for example, as shown, the adapter 24 includes a continuous inner hollow portion.

In some implementations, as illustrated below in FIG. 6 , the suction front end 27 can be removed from the adapter 24 to replace the one-way filter 26 .

6 is a schematic diagram of the adapter 24 with the suction front end 27 removed. In some implementations, the adapter 24 can be separated into at least two components, such as the suction front end 27 and the one-way filter 26.

The suction tip 27 can be connected to the one-way filter 27, for example, by means of internal threads on the one-way filter 27 and complementary external threads on the suction tip 27. Twisting the one-way filter 27 and the suction tip 27 can connect them, while twisting in opposite directions can disconnect them. In this way, the suction tip 27 can be cleaned and sterilized between uses. In embodiments where the adapter 24 includes the filter 25, the adapter 24 may not be removed separately, but may need to be replaced when necessary.

Some embodiments of the present invention have been described. However, it should be understood that various modifications can be made without departing from the spirit and scope of the present invention. For example, although reference to a special connection type has been provided, other types of connections are possible (such as other types of sleeves, female/male connections, etc.). Similarly, although a specific type of valve or filter has been provided as a reference, other valves or filters are possible (such as slide valves, etc.). In addition, although one or more components of the aspirator have been provided to allow separation as a reference (such as for cleaning), specific implementation may not include a separation point, but is formed as an integral structure (such as by a molding process, etc.). Therefore, other embodiments are within the scope of the claims.
