Description

FIELD OF TECHNOLOGY

[0001] The proposed utility model relates to devices for cleansing the upper respiratory tract, in particular the nasal passages in children, in particular children of preschool age, and can be used either manually with the application of negative pressure by another person, or in conjunction with a vacuum device that creates negative pressure.

BACKGROUND

[0002] Some people are unable or unable to independently clear their upper airways by blowing their nose. For example, children, especially children of primary preschool age, do not know how to blow their nose and learn to do this only to a more conscious age. Meanwhile, a change in the quality and quantity of mucous secretions in the nasal passages is practically the first and very important physiological reaction of a healthy organism to the appearance of pathogenic microorganisms in the upper respiratory tract or the entry of viruses, and therefore regular cleaning of the upper respiratory tract from secretions is important in such situations to maintain normal microflora of the upper respiratory tract and the general state of immunity.

[0003] An aspirator is disclosed in the prior art, disclosed in WO03035144 (A1) (publ. 05/01/2003) comprising a detachable housing consisting of a proximal portion that includes an opening for receiving scrubbed contents, and a distal portion containing an opening for attaching to the source negative pressure. At the same time, a filter is provided in the proximal part of the known aspirator, which is located so as to completely overlap the body cavity perpendicular to the air flow from the hole for receiving the scrubbed contents and, thus, prevents the scrubbed contents from entering the region of the hole for connection to a negative pressure source. This design reliably protects the distal part and, in particular, the hole for attaching to the source of negative pressure from contamination by the contents to be cleaned. However, as the filter becomes dirty, the efficiency of use of the device is greatly reduced, and for its intended use, the filter must be replaced.

[0004] To maintain good hygiene, commercially available analogues of the known device, such as the Novartis Otrivin Suction Pump, suggest replacing the entire proximal portion of the housing, including the filter. Such a solution effectively solves the hygiene problem of reuse of the device, but involves the need to use a relatively large consumable, which, in particular, significantly increases the cost of the product for the user.

[0005] Such aspirator designs that do not contain filters are also known in the art. For example, the Pigeon aspirator (http://www.akusherstvo.ru/magaz.php?action=show_tovar&tovar_id=34723), selected as the closest analogue of the proposed utility model and having a detachable body consisting of a proximal part that contains a hole for acceptance the contents to be scrubbed, a channel for removing the contents to be scrubbed, and an opening for connecting to a negative pressure source, and a distal portion containing a chamber for collecting the contents to be scrubbed, the proximal portion and the distal portion of the body having the design that when they are connected, the channel for removal of the contents to be scrubbed enters the chamber for collecting the contents to be scrubbed. It is possible to maintain hygiene of such an aspirator by washing parts of the housing, which is facilitated by the fact that the housing is detachable. Prevention of the scrubbed contents from entering the area of the hole for connection to a negative pressure source is provided by the presence of a special channel for removing the scrubbed contents connected to the hole for receiving this content, and by allowing this channel to enter the chamber for collecting the scrubbed contents when connecting parts of the housing. Nevertheless, when connecting the proximal and distal parts of the body (when the aspirator is assembled), the outlet of the indicated channel and the hole for connection to the source of negative pressure appear in the same cavity of the channel and are not separated in any way, because of which there is a chance of the accumulation in the chamber contents in the area of the hole for attachment to a source of negative pressure. For example, when using an aspirator, involuntary movements and rotations of the device are possible, as a result of which, under the action of gravity, the contents accumulated in the chamber can move to the region of the hole for attachment to a source of negative pressure. At the same time, getting the scrubbed contents into this area significantly increases the likelihood of contamination of the connecting elements between the aspirator and the source of negative pressure, as well as disrupting the operation of the aspirator as a whole, since these connecting elements are relatively narrow and can become clogged when the scrubbed contents get into them. Among the shortcomings of the known aspirator, one can also note the not quite ergonomic shape of the case, which, with sudden movements, typical, for example, for small children, can disrupt the convenience and non-invasiveness of using the device. An important factor is the complexity of the shape of the case, the production of which is expected to be more complicated than the manufacture of cases of a simpler and more technologically advanced form.

[0006] Thus, the present utility model addresses the technical problem of preventing the contents of the aspirator being cleaned from entering the area of the hole for attachment to a negative pressure source. In addition, there is a need for a nasal aspirator for cleansing the upper respiratory tract, which would be simple to manufacture, easy and inexpensive to maintain (in particular, for sanitary and hygienic maintenance).

DISCLOSURE OF THE ESSENCE OF A USEFUL MODEL

[0007] According to this utility model, a nasal aspirator for cleansing the upper respiratory tract is provided, comprising a body containing a proximal part, the inner volume of which is divided by a septum into a first part and a second part having an opening for receiving scrubbed contents, and configured to detachably connect to the proximal part of the distal part containing an internal channel connected to the hole for connection to a source of negative pressure, and when connecting the proximal hour The channel and the distal part of the housing enter the first part of the housing with the institution of its end beyond the edge of the partition and with the communication of this channel with the second part of the housing.

[0008] The proposed design of the nasal aspirator provides a technical result in the form of reducing contamination of the inner cavity of the aspirator body with the scrubbed contents, in particular, more reliably preventing the scrubbed contents from entering the area of the hole for connection with a negative pressure source, without the use of replaceable elements (eg filters) that the proposed aspirator has a housing containing a proximal part, the internal volume of which is divided by a partition into the first part l and the second part, having an opening for receiving the scrubbed contents, and made with the possibility of detachable connection with the proximal part of the distal part, containing an internal channel connected to the hole for connection to a source of negative pressure, and when connecting the proximal part and the distal part of the body, the channel enters the first part of the housing with the institution of its end beyond the edge of the partition and providing communication of this channel with the second part of the housing. The location of the holes for receiving the scrubbed contents in the proximal part, and the holes for attaching to the source of negative pressure in the distal part provides spatial diversity of these holes and their removal from each other. Of particular importance is the fact that the internal volume of the proximal part is divided by a partition into the first part and the second part, and in the aspirator assembly, the hole for receiving the contents to be scrubbed and the channel connected to the hole for connection to the negative pressure source are in different parts of the proximal part . Such design features make it possible to prevent the scrubbed contents from entering the region of the hole for attachment to a source of negative pressure without resorting to using any filtering scrubbed content elements.

[0009] In addition, the proposed design provides easier sanitary and hygienic maintenance of the aspirator, and is also simpler and more efficient in production and use than the analogues known to the applicant. These advantages are achievable due to the simple form of the structure and its internal cavities, which are easily accessible after disassembling the body into the proximal and distal parts, so that the internal surfaces of the body cavity can be washed without difficulty with water or a sterilizing solution. The absence of the need to replace any filtering or contaminating elements makes the aspirator easier to manufacture and use, and the possibility of prompt sanitary and hygienic maintenance after each use increases the hygiene of the device.

[00010] According to some of the embodiments of the proposed utility model, the area of the proximal part of the body in which the hole for receiving the scrubbed contents is located is made conical in shape, in the shape of a convex body of revolution and / or in a round elongated shape, which makes it possible to insert the specified area into the nasal passage. According to some embodiments, at least the region of the proximal portion in which the opening for receiving the scrubbed contents is located is made of elastic material. These features provide non-invasive use of the device.

[00011] According to some embodiments, the aspirator comprises an elastic tube configured to attach to a hole for connection to a negative pressure source. These features facilitate the use of an aspirator with a source of negative pressure due to the fact that the elastic tube can be easily connected, for example, to the fitting of the microcompressor, while providing greater freedom in the placement of the aspirator.

[00012] According to some embodiments, the aspirator also comprises a mouthpiece configured to attach to the elastic tube. Thus, a person inhaling air through a mouthpiece can serve as a source of negative pressure. In such an embodiment, the aspirator is particularly suitable for home use by parents to cleanse the baby’s upper respiratory tract. For convenient and durable use of an aspirator with a mouthpiece, according to one embodiment, the aspirator also includes a stopper configured to attach to the elastic tube between it and the mouthpiece.

IMPLEMENTATION OF A USEFUL MODEL

[00019] According to one of the preferred embodiments of the present utility model, the aspirator comprises a detachable body (1) comprising detachably connected proximal part (4) and a distal part (5) (Fig. 1). The proximal part (4) of the aspirator is divided by a septum (9) into the first part (3) and the second part (2). In use, the aspirator is preferably positioned so that the first part (3) is located above the second part (2). In FIG. 1, the aspirator is shown assembled, with the hole (5) for receiving the scrubbed contents being in the second part (2), and the hole (8) for connecting to the negative pressure source through the internal channel (7) communicates with the first part (3). When the aspirator is assembled and the proximal part (4) is connected to the distal part (6), the channel (7) enters the first part (3) of the proximal part with the end of it past the edge of the septum (9), while between the first part (3) and the second part (2) provides air exchange. It should be noted that a deeper introduction of the channel (7) into the second part (2) allows for additional reliability to prevent the scrubbed contents from entering the region of the hole (8) for connection to a negative pressure source.

[00020] FIG. 1, arrows also indicate the directions of the air flow (dotted line) and the flow of the contents being scrubbed (continuous line). It is seen that under the influence of negative pressure created in the housing after connecting a negative pressure source to the hole (8), the air flow passes from the hole (5) to receive the contents to be cleaned into the second chamber (2), and then through the space formed between the inner surface the first part (3) of the proximal part (4) and the walls of the channel (7), into the first chamber (3). After that, the air flow has the only way for further propagation - through the channel (7), which is a continuation of the hole (8) for connection to a negative pressure source. In this case, the scrubbed contents under the action of negative pressure created in the aspirator body is forced to enter the hole (5) for receiving the scrubbed contents and enters the second part (2) of the proximal part (4). In this case, getting the scrubbed contents into the region of the end of the channel (7), which is a continuation of the hole (8) for connecting to the source of negative pressure, causes several obstacles caused by both natural conditions (gravity and adhesion of viscous scrubbed contents to the inner surface of the housing (1)) and design features provided for this: the contents entering the second chamber (2) are separated from the end of the channel (7) not only by a partition (9), but also by the walls of the channel (7), which rodolzhenie holes (8) for connection to a negative pressure source.

[00021] In the embodiment of the utility model shown in the figures, the dividing wall (9) is made in the proximal part (4) of the body, so that when connecting the proximal and distal parts of the body, the end of the internal channel (7) enters the first part (3) and is located on some distance from the edge of the partition wall (9).

[00022] FIG. 2A-2B show a sectional view along line AA of the proximal part (4), the distal part (6) and the body (1) assembly, according to one embodiment of the proposed utility model. According to the shown embodiment, between the proximal and distal parts (4, 6) of the body (1), a telescopic connection is realized. For this, the distal end of the proximal part (4) has a diameter that ensures its insertion into the mating part of the distal part (6) with its tight fit on the proximal part (4). As seen in FIG. 2A, the septum (9) is made in the proximal part (4). In FIG. 2B shows a cross-sectional view of a distal part that contains a channel (7), which is a continuation of the hole (8) for connection to a negative pressure source. According to the shown embodiment of the utility model, the channel (7) is made with a technological stiffness element (11), which provides structural rigidity and simplifies the production of the product. When connecting the proximal part (4) and the distal part (6), the channel (7) is included in the first part (3) of the proximal part (4) of the body. In this case, between the walls of the channel (7) and the inner surface of the upper part (3) located in the proximal part (4) of the body, a space is formed for air exchange between parts (2 and 3). Thus, the scrubbed contents from the second part (2) are prevented from entering the first part (3) and into the inner channel (7), which in turn prevents the scrubbed contents from entering the region of the hole (8) for attaching to the negative pressure source, thereby that the receiving scrubbed contents of the second part (3) of the proximal part (4) of the body is separated from the hole (8) for connection to the negative pressure source by a partition (9), as well as the walls of the channel (7).

[00023] For the convenience of using the proposed aspirator, according to some embodiments of the utility model, the region of the proximal part in which the hole (5) for receiving the scrubbed contents is located is made conical in shape, in shape of a convex body of revolution and / or in a round elongated shape, which makes it possible to insert specified area in the nasal passage. This embodiment of the proximal part (4) of the housing (1) provides a more reliable fluid exchange between the aspirator and the upper respiratory tract.

[00024] To increase the atraumaticity of the aspirator, at least the region of the proximal portion in which the opening (5) for receiving the scrubbed contents is made of elastic material. In order to provide a more tight connection between the proximal part (4) and the distal part (6), preferably the entire proximal part (4) of the aspirator body (1) is made of an elastic material (for example, silicone and the like).

[00025] The intended use of the proposed aspirator is possible both in conjunction with special devices that create negative pressure (for example, compressors, microcompressors), and without special devices, as a simplified home remedy for cleaning the upper respiratory tract by creating inspiratory pressure from the side of the access hole to a source of negative pressure. For the convenience of the location of the aspirator when using it, according to some implementation options, it is also provided that it has an elastic tube (10) made with the possibility of attaching one of the ends to the hole (8) for connection to a negative pressure source. At the other end, an elastic tube (10) is connected to a negative pressure source. In addition, for home use, according to some embodiments of the proposed utility model, a mouthpiece (11) is provided that is configured to attach to said tube (10), and if necessary also a limiter (12) configured to attach to an elastic tube ( 10) between her and the mouthpiece (11). The limiter (12) can be made in the form of a tubular part containing a cone-shaped thickening that prevents excessive insertion of the mouthpiece (11) into the elastic tube (10). As shown in FIG. 3 embodiment, the limiter (12) for convenience also contains a wide flange, which, according to the shown embodiment, is made in the form of petals. In some other embodiments involving the use of an aspirator to clean the upper respiratory tract of children, the limiter (12) can be made in the form of any other element that distracts the attention of the child. In other embodiments, an elastic tube is attached to a compressor or microcompressor, for example via a fitting.

[00026] Using the proposed aspirator is intuitive and easy to do at home. To clean the upper respiratory tract, the area of the proximal part (4) of the aspirator body (1) in which the hole (5) for receiving the scrubbed contents is located is arranged to exchange fluid with the patient’s nasal passage and then provide negative pressure inside the case (1) an aspirator, which forces the accumulations of mucus and / or other substances present in the upper respiratory tract to move through the opening (5) to accept the scrubbed contents into the second part (2) of the proximal part (4) of the body. When using the proposed device without special devices, an elastic tube (10) is attached to the hole (8) and a mouthpiece (11) is attached to it. The area of the proximal part (4) of the aspirator body (1), in which the hole (5) for receiving the scrubbed contents is located, is arranged to exchange fluid with the patient’s nasal passage, the mouthpiece (11) is tightly wrapped around the lips, and then a breath is taken which leads to the occurrence of negative pressure inside the housing (1) of the aspirator.

[00027] To carry out the sanitary-hygienic treatment of the proposed aspirator, all its components are separated and washed in water, a soap solution, a sterilizing solution and / or sterilized by heat treatment if this is possible with respect to the materials used in the manufacture. An important advantage in this case is that the housing design of the proposed aspirator provides easy access to its inner surface for various cleaning agents. In addition, since the proposed design reliably protects the upper chamber (3), the channel (7), and even more the hole (8) connected to it for attaching to the source of negative pressure from ingress of scrubbed contents, the sanitary-hygienic treatment of the aspirator is also simplified.

[00028] It should be understood that the embodiments of the proposed technical solution described here are given only as an example and do not limit the essence of the present invention, which is defined solely by the attached utility model formula. All of the implementation options described here can be fully or partially combined without departing from the essence of the present utility model and without losing the benefits provided by the proposed utility model. One skilled in the art will understand that materials, types of joints, the shape of internal cavities, and other features of an aspirator can be different without departing from the essence of the utility model and without detracting from the benefits it provides.
