RU214962U1 - Breathing nozzle-inhaler for an aerosol can - Google Patents

Abstract

The aerosol canister inhaler is designed for use with aerosol canisters filled with oxygen-air or other breathing mixture. The proposed mask is made of a polymeric material and contains a hole for putting on the nozzle of the dispenser-spray bottle. What is new is that it is structurally made with a contour fit in the area of the nasolabial triangle and is equipped with fasteners-hooks and an emphasis that ensure its fixation to the rim of the aerosol can from its inner and outer sides locally. Due to this, the mask simultaneously performs the function of a cover on the balloon, but with its best contour fit to the face in the area of the nasolabial triangle compared to mask-covers with a closed contour.

Description

The utility model relates to a breathing nozzle-inhaler and is intended for use with aerosol containers filled with oxygen-air or other respiratory mixture (hereinafter referred to as oxygen cylinders).

Oxygen cylinders have gained wide popularity, especially at the present time, because they allow you to quickly replenish the lack of oxygen in the body, which improves reaction speed, concentration, stimulates mental activity, relieves headaches and dizziness, alleviates the symptoms of hypoxia and heart disease, heart attack and angina pectoris .

The Applicant considers it necessary to provide explanations regarding the used concepts of "mask", "breathing nozzle-inhaler" for their unambiguous interpretation for the purpose of this application. There are a large number of types of masks with different purposes, for example, a medical mask is a hygienic (sanitary and hygienic) product that covers the wearer's mouth and nose with a filter and is designed to protect against inhalation of liquid aerosols. Oxygen masks are designed to supply an oxygen-air mixture through them and maintain the oxygen level necessary for the normal functioning of the body. These masks deliver an oxygen mixture directly into the patient's respiratory tract and are connected to an oxygen concentrator and are used, as a rule, in medical institutions and in the provision of emergency medical care. Masks are also traditionally called nozzles for oxygen cylinders, which are used to inhale an oxygen-air mixture that performs not a protective function, but an inhalation one, their purpose is to direct the flow of short-term inhaled oxygen from a canister for more efficient consumption of gas or aerosol due to its concentration inside the mask. The subject matter of this application is a breathing nozzle-inhaler for an aerosol can or a mask designed to direct the flow of gas or aerosol for short-term inhalation from a can.

In the prior art, two types of devices are known and most common, which are used in portable cylinders. These are soft masks made of PVC or silicone that either come with the balloon or are sold separately and are used after removing the cap on the balloon. The advantage of such masks is their ergonomics in use due to a comfortable fit to the face due to the elastic material. The disadvantages of such masks include the fact that an additional connecting tube is required to connect them to the balloon, but it is also inconvenient to wear such a mask constantly with a balloon. In addition, the use of such masks, which have a contoured shape and flexibility, is only possible as an additional element of the balloon configuration, because it will not provide the function of a cap to protect the spray bottle dispenser from accidental impact.

The second type is solid masks or nozzles - inhalers, which simultaneously act as a cylinder cap. Such covers - masks are often made of polypropylene, which has a comparative hardness.

The advantage of such inhaler nozzles is that they always come with a balloon. However, the technical problem lies in the fact that the known solutions of such inhaler nozzles are not convenient to use due to the use of inelastic solid material and the shape, which is structurally limited by the balloon. The inconvenience lies in the fact that they do not cover the nasolabial triangle, but only remotely cover part of the face. This form of mask-lid entails another disadvantage, which consists in a large loss of the inhaled mixture due to non-adherence to the face.

This utility model relates to a breathing nozzle-inhaler for an aerosol can (mask-cover), which simultaneously performs the functions of a cover-nozzle for an aerosol can and an inhaler (mask) that ensures the direction of the inhaled contents of the can (oxygen, respiratory mixture).

Known from the prior art is the source of information RU 71884 U1, 03/27/2008, which discloses a gas cartridge equipped with a guide device for sprayed gas, made in the form of a respirator (oxygen mask) made of polymeric material. The device is aimed at improving the performance properties of the product by increasing the direction of oxygen spraying. The disadvantage of the known solution is the inconvenience in its use due to loose fit to the face, as well as a large loss of oxygen for this reason. The description does not disclose a means of attaching the mask to the balloon, which makes it unclear whether the mask is suitable for any valve or given balloon design.

Also known from the prior art is a cover-mask for an aerosol can (see RU 169673 U1, 25.05.2016 B65D 83/30), which combines in one device a mask for targeted spraying of an aerosol and a cover that protects the inside of the mask from rapid contamination during transportation and storage. The cover-mask consists of two parts, the lower of which is fixedly fixed on the balloon, forms the lower cavity and walls of the mask, and has a flexible or hinged connection with the upper part, which, when closed, covers the lower cavity and walls of the mask, forming a cover that protects the inner part masks from contamination, and when opened around the connection axis, being the upper cavity and walls of the mask, it forms the mask as a whole.

The disadvantages of the known solution include the unsuitability of such a mask for longer use than a single spray of an aerosol, since the shape of the lid will not allow the user to comfortably use the mask in the area of the nasolabial triangle, and the mask does not provide rational use of the aerosol due to the lack of a contour fit of the mask to the face. The lid can be used for certain types of cylinders where the hole in the lid will be aligned with the cylinder valve.

The closest in terms of essential features is the mask-cover described by CN 213609482 U, 07/06/2021. As described, the portable oxygen breathing cylinder is provided with a breathing mask 20 that is put on (installed) on the oxygen cylinder 10 as a cover, allowing the user to carry it around. The inside of the breathing mask is hollow. The first end of the breathing mask is provided with a connecting hole 241, and the second end of the breathing mask 20 is provided with a hole adapted to the shape of the body of the oxygen cylinder 10. To use the cylinder, the mask is removed and turned over, connecting the hole 241 on the breathing mask with the air outlet 30, while the hollow part of the mask is used for its intended purpose for installation to a person's face. The gas from the oxygen cylinder enters the breathing mask 20 through the air outlet 30. The mask is provided with an air vent 231 to facilitate the wearer's ventilation and a connection port 241 adapted to the connection tube 32 on the balloon.

The mask, which simultaneously functions as a cover, has a completely closed contour along the lower part, due to which the product is “fitted” onto the rim of the aerosol can from the outside and, in fact, wraps around it around the perimeter. This imposes significant restrictions on the shape of products, and also complicates the process of manufacturing products due to the presence of undercuts on its inner surface, i.e. a casting section having an opposite slope with respect to the molding slopes of the entire casting as a whole. In addition, such a cap-mask can be used exclusively for a cylinder suitable for cap diameter parameters. Another disadvantage is that the mask is very inconvenient to use, which leads to unnecessary waste (overspending) of the gas used.

The technical problem solved by this utility model is the creation of a universal solid, elastically deformable breathing nozzle-inhaler, which simultaneously combines the functions of a cap on a gas (aerosol) cylinder and an inhalation mask that can be used for cylinders with a rolling seam using a standard distributor, at the same time, meeting the requirements of ergonomics when inhaling an aerosol and reducing losses due to a more contour fit of the mask to the user's face.

The technical result consists in providing the mask with the function of a lid on a gas (aerosol) cylinder with its best contour fit to the face in the region of the nasolabial triangle, in comparison with mask-lids having a closed contour.

This is achieved by the fact that the mask for the aerosol can is made of a polymeric material, has a contoured shape that ensures fit to the user's face in the area of the nasolabial triangle, a hole for putting on the nozzle of the dispenser-spray of the can and made on its lower part of the fasteners-hooks that provide it fixation on the aerosol container during its transportation due to the local girth of the rim of the container from its lower, inner and outer sides. Fasteners-hooks are made with the formation of through air intakes in the mask.

The implementation of the utility model of the above design ensures the achievement of the claimed technical result due to the possibility of attaching a mask of a contour polygonal shape adjacent to the user's face in the area of the nasolabial triangle, due to new fasteners-hooks located in the lower part of the mask and which locally wrap around the rim of the balloon from its lower, inner and outer sides, thereby providing the mask with an additional function - covers.

In addition, one skilled in the art will appreciate that the lower part of the mask is the part in contact with the mouth, chin, compared to the (upper) part of the mask with contact with the cheeks and bridge of the nose, due to the structure of the user's (human) face.

At the same time, the implementation of fasteners-hooks with the formation of through air intakes in the mask provides the level of safety of use necessary for such devices, due to suction during inhalation of ordinary air to dilute the concentration of oxygen (or other gas, aerosol) under the action of a pressure difference.

The essence of the claimed utility model is illustrated by drawings.

Fig. 5 shows the use of the mask.

In FIG. 1 shows a prototype from CN 213609482 U, 07/06/2021, in which the mask is also a cover. The disadvantages of the well-known technical solutions mentioned above.

With reference to FIG. 2, the inhaler nozzle includes fastenings-hooks (2) and (3), an emphasis (4), through air intakes 5 formed by fastenings-hooks, as well as a hole 6 for putting on the nozzle of the dispenser-spray bottle.

The gap between the hooks (2) and (3) act as air intakes so that air can enter the mask to dilute the concentration of oxygen (or other gas, aerosol) under the action of a pressure difference when oxygen is inhaled, and thereby ensuring safety of use.

The number and shape of fasteners - hooks due to the comfortable volume of inhaled air. As an example, in FIG. 2 shows five fasteners-hooks. The smaller the total area of the air intakes, the lower their throughput, the more difficult it is to inhale oxygen. The number of hooks is also determined by the requirement of fastening reliability.

The mask is made of a polymeric material, for example, polypropylene, which has such properties as elasticity and deformability (material susceptibility to change) with sufficient hardness, which ensures the protective function of the cover when installed on a balloon and at the same time fits to the user's face in the area of the nasolabial triangle.

The body of the mask is preferably transparent to monitor the condition of the skin of the nasolabial triangle. The edges of the mask are ergonomically shaped, due to the physiological characteristics of the human face, and are designed in such a way that it reduces the leakage of the supplied gas from under the mask space. To this end, the shape of the mask can also be polygonal.

The fixation of the mask on the aerosol can during its transportation is ensured by local wrapping of the rim (rolling seam) of the can from its inner and outer sides thanks to the hooks (2) and (3) and the stop (4).

In FIG. 3 shows the position of the mask during transport, where the mask is locally attached by hooks (2) and (3) to the rim of the balloon formed by the rolling seam. Fastening is carried out to the rim from the inside and outside. In this position, the mask provides the function of a cover that protects the spray dispenser from accidental impact, pressing.

Fig. 4 allows you to understand that when putting the product on the rim of the cylinder (1), the hooks (2) and (3) diverge slightly, allowing the rim to “squeeze” between them. When the rim reaches the stop (4), the hooks (2) and (3) return to their original position and the rim is clamped between the hooks (2), (3) and the stop (4). It is fixed, the mask is placed on the balloon as a cover.

If necessary, use the contents of the aerosol can, the mask is removed from the rim of the can and through the hole 6 is put on the nozzle of the dispenser-sprayer (Fig. 5), the mask is ready for use.

When using a balloon with a mask placed on it in this way, the balloon is brought to the face in the region of the nasolabial triangle. As shown in FIG. 5, the mask, due to its contoured shape, ensures that it fits close to the wearer's nose and mouth.

For further use, it is necessary to press the spray dispenser and inhale at the same time, ensuring that the necessary aerosol (gas) enters the respiratory organs.

It is also worth noting that when using a mask with a balloon, through air intakes made at the locations of the fasteners-hooks provide suction when inhaling ordinary air to dilute the concentration of oxygen (or other gas, aerosol) under the action of a pressure difference.

To transfer the cylinder to the transport position, it is necessary to perform the action of installing the mask on the rim of the cylinder in the reverse order.

Thus, the design of the proposed utility model provides the function of a cover on a gas (aerosol) cylinder with the best contour fit in the area of the nasolabial triangle on the user's face, compared with an analogue mask-cover that repeats the cylindrical contour of the cylinder, the loss (overrun) of the gas used is reduced and, as a result, efficiency increases when using an aerosol can.
