Description

Flow restriction and filtering device nasal ventilator to prevent the entry of allergenic substances and strengthening of inspiratory musculature.

Technical sector

This invention relates to a "Device of restriction and filtration of nasal ventilatory flow to prevent entry of allergenic substances and strengthening of inspiratory musculature ", being its application in the training of the ventilatory muscles, responsible for the phase inspiratory, useful for improving aerobic endurance in sports subjects, sedentary and troubled people respiratory, as well as for air filtration inhaled from the inspiratory phase.

During exercise, muscle function skeletal is to produce body movements while that of the respiratory muscles is ventilate the lungs to get enough oxygen and remove metabolic waste like dioxide from carbon.

The breathing mechanism, especially during physical and sports activity must be governed by an inspiration nasal and an oral exhalation, so that the inspired air is heated, moistened, filtered through the nostrils and expelled, more quickly and easily, by mouth.

In the inspiratory phase, at rest, they act muscles such as the diaphragm, the external intercostals and paraesternales and in the expiratory phase the action of the gravity. During physical activity, in the inspiratory phase, the aforementioned muscles act - joining muscles of the shoulder girdle - and in the expiratory phase, in addition to the gravity action, internal intercostal muscles act and of the abdominal wall. All these muscles are susceptible to improvement through appropriate training devices such as "Restriction device and filtration of the ventilatory flow nasal to prevent the entry of allergenic substances and strengthening of the inspiratory musculature. "

In numerous investigations regarding physical activity, sport and health it has been shown that the training of the muscles responsible for the inspiration of the air is beneficial to increase respiratory capacity, put which facilitates the entry of air into the lungs and decreases the fatigue caused by exercise.

Similarly, the need for perform an air filtration inspired by those with allergic reactions to certain allergenic components such as mites, pollens, dust, etc., or simply in people who they want to increase air quality inspired by populations with High levels of pollution. "Restriction device and filtration of the nasal ventilatory flow to prevent the entry of allergenic substances and strengthening of the musculature inspiratory ", allows the filtering of these components, improving inspired air quality and, by extension, health of the subject who uses it.

Modifying the characteristics of porosity of the fabric used in its manufacture allows to manufacture several types of "Restriction devices and filtration of ventilatory flow nasal to prevent the entry of allergenic substances and strengthening of the inspiratory musculature ", depending on whether a higher or lower level of airflow restriction is required and filtering capacity.

"Restriction and filtering device of nasal ventilatory flow to prevent the entry of substances allergens and strengthening of inspiratory muscles "is useful not only for subjects with respiratory problems, but also in athletes, since it has been shown that a training of inspiratory muscles, has a positive character in the results of performance in improving aerobic endurance.

There are many studies of the specific training of inspiratory muscles through the control of ventilation and the specific work of respiratory muscles, however, only Jackson P. Wai. "Ventilatory Muscle Endurance Training, Effect on Endurance Exercise Performance in Trained Cyclists". The Chínese University of Hong Kong, 1995 , studies the effects of inspiratory muscle training through flow restriction in resistance training itself, with values of improvement in maximum oxygen consumption (+ 5%) and resistance performance 30 minutes (+ 9%) on cyclists. However, this author used as a flow restriction system a conventional mask with limited flow restriction capacity that encompassed nose and mouth.

With the exception of the previous model, in the field of physical and sports activity, most devices developed so far enable the training of the inspiratory musculature, but they are used in positions static or for laboratory training, not allowing its use in real training situation as it is in a sports field or On a running track.

"Restriction and filtering device of nasal ventilatory flow to prevent the entry of substances allergens and strengthening of inspiratory muscles ", allows its use both in static situations, sitting in a chair or lying on a bed, as in dynamic situations, such as for example walking or running on a sports track.

State of the art

There are several devices on the market nasals intended for the prevention and treatment of disorders and malformations in the nasal passages and therefore possible breathing complications and few devices specifically to the training of the ventilatory muscles.

Similarly, there are various market devices for air filtration inspired, being the most feature the use of masks that, occupying and protecting the nasal and oral cavities, they protect the organism from the entry of allergenic substances and contaminants.

Next we will explain the most characteristic.

Improved hygienic mask. ES0267091U: It consists of a mask of those that are formed by a body of breathable material and adaptable to the user's face particularly allowing the protection of the nose and mouth of the same, covering them. Inside and in front of the area where they are left nose and mouth protected, a mattress or pad is provided volatile liquid absorbent by bonding or adhesion by means conventional, given the particular circumstance that the impregnation of the mattress or pad by volatile liquid creates a breathable atmosphere of high quality and effectively healthy.

This type of mask, unlike the "Restriction device and filtration of the ventilatory flow nasal to prevent the entry of allergenic substances and strengthening of the inspiratory musculature, "just filters, but does not allow more work of the inspiratory muscles during use To this add the largest size of the device, by also filtering the air inspired by mouth. By On the other hand, these types of masks are more uncomfortable to use, They cause heat and have a negative aesthetic effect.

US6092521A nose warming mask: We we are faced with another type of mask, like the one before exposed. This device consists of a small mask that completely covering the nose allows heating with greater Ease the inspired air and filter the particles Causes of allergies and hay fever. Unlike "Restriction device and filtration of the ventilatory flow nasal to prevent the entry of allergenic substances and strengthening of the inspiratory musculature ", this mask does not allow the strengthening of the inspiratory musculature, since in its manufacture and in its claims there is no modification of porosity or tissue size to control the inspired air flow, but simply filters it. For another side the way of subjection in the nose is by means of simple straps to hold the mask to the face and not as is the case with "Restriction device and filtration of the ventilatory flow nasal to prevent the entry of allergenic substances and strengthening of the inspiratory musculature ", whose form of Fastening is by means of adhesive substance. On the other hand, the minor Size, location, manufacturing structure, and benefits for the strengthening of the inspiratory musculature are clear significant evidence and differences regarding this device.

Nasal Filter ES1043922U: Refers to a filter nasal whose purpose is the purification of the air inhaled by the people, in order to prevent possible diseases, which may contracting through the respiratory system, such as rhinitis allergic It consists of two pieces that act as small covers that are inserted in the nostrils, which they are joined together by moldable strip. Unlike "Restriction device and filtration of the ventilatory flow nasal to prevent the entry of allergenic substances and strengthening of the inspiratory muscles ", nasal filter has of being introduced into the nostril, and may cause user discomfort in its use and being easily expelled from the nostril in case of nasal exhalations. To it add that has no airflow restriction system inspired to the strengthening of the respiratory muscles or at least not reflected in the request. On the other hand, the form and device structure differs greatly from the device presented.

Nasal inspiratory resistance trainer (NIRT) US20090205642 A1: It consists of a device that applied in the outside of the nose increases the difficulty in carrying out the nasal breathing when pressing the nasal fins and reducing ostensibly the air intake during inspiration. Saying device has basically 3 functions: the treatment and prevention of respiratory disorders such as asthma or rhinitis; a decrease in blood pressure that can be seen especially benefited those hypertensive subjects and reduces the tendency to inhale orally while sleeping reducing so Both snoring.

Your application may be somewhat annoying because to its design in the form of tweezers, not being suitable for use While playing sports. Similarly, as a negative aspect highlights the impossibility of controlling the pressure exerted on the nasal fins, since this condition will depend not only of the material with which the device is manufactured but also, and what which is more important, because of the size and anatomical nasal shape of the subject. In addition, it does not allow air filtration inspired by the respiratory process

Apparatus for hypoxic training and therapy US20050252512 A1: It consists of a tube with a nozzle which is connected to a chamber where carbon dioxide is absorbed produced by the breath, said camera is in turn connected with the atmosphere When the subject inhales through the tube, the air which receives the lungs contains a percentage of oxygen and dioxide carbon-like air located at the selected height. For the both the function of this device is to reproduce the resistance training at height, improving breathing and reducing possible breathing difficulties.

Ventilatory muscle training apparatus US19814301810: This device is similar to the previous one although quite more complex. Its function is to work the muscles that they take part in both inhalation and exhalation, improving ventilation during exercise which is special importance for subjects suffering from some kind of problem respiratory.

These last devices explained have the same function of improving respiratory ventilation, however due to the machinery they entail it would be impossible to use while any type of sport is performed. Therefore, it does not allow its use in real situation of resistance training in runners athletics or any other sport and does not filter the air inspired.

In relation to the devices explained and described above highlight the strips referred to as Nasal Dilator US20016318362 B1. They are flexible adhesive strips which are applied on the outside of the nose which prevent the outer wall tissue of the nasal passages retracts during breathing Its main function is to relieve the block nasal during inhalation and also due to its design you can apply overnight when the problem of nasal blockage During inhalation it is more acute. In terms of design it is the most similar to the ventilatory flow restriction device by the use of adhesive strips however is not intended for strengthening of the ventilatory muscles since its function is to do the opposite effect to the "restriction device and filtration of the nasal ventilatory flow to prevent the entry of allergenic substances and strengthening of the musculature inspiratory ", since instead of facilitating the entry of air during inspiration, the proposed device makes it difficult and leaks the air inlet

Nasal Dilator EP1033118A1 (3M INNOVATIVE PROPERTIES CO). This device is very similar to the Nasal Dilator US20016318362 B1. They are flexible adhesive strips that are applied on the outside of the nose which prevent the tissue of the outer wall of the nasal passages retracts during the breathing. On the other hand, it has microcapsules that contain volatile substances that break when the device is pressed and that They are located at both ends and in the central area, place where pressure is made when placed on the nose. its main function is therefore nasal dilation, to facilitate the passage of air through the nostrils so it performs the effect contrary to "Flow restriction and filtering device nasal ventilator to prevent the entry of allergenic substances and strengthening the inspiratory muscles. "In addition to this clear and fundamental difference, the "Restriction Device and filtration of the nasal ventilatory flow to prevent the entry of allergenic substances and strengthening of the musculature inspiratory "allows adding pharmacological substances and / or deodorizers, but they don't need to be found microcapsulated to be released by pressure, but impregnated in the tissue located only in the entrance area of the air in the nostril, thus facilitating more direct and rapid, the entry of the drug or substance. So the location and mode of incorporation of the medications or substance added are also substantial differences with respect to Nasal Dilator, to which we obviously add that this device dilates the nostril and does not allow the strengthening of the inspiratory, objective and primary use musculature and characteristic of the "Restriction and filtering device of nasal ventilatory flow to prevent the entry of substances allergens and muscle strengthening inspiratory. "

ES2239314T3 Skin Dressing: For the similar to the present device highlight the dressings or commonly known as "strips", used as a means of protection against pollutants and healing of small wounds produced on the body surface. This similar device structure but different composition and function with respect to "Restriction device and filtration of the ventilatory flow nasal to prevent the entry of allergenic substances and strengthening of the inspiratory musculature "includes some adhesive strips that do not alter the skin and that is covered by a side of a flexible non-adhesive polymer and which optionally is coated, on the other hand, with a separation layer that can withdraw. Although in its design it can resemble "Restriction device and filtration of the ventilatory flow nasal to prevent the entry of allergenic substances and strengthening of the inspiratory musculature ", its structure and features do not allow its use as a filtering system of air. Suffice it to note that if these types of dressings are placed in the entry of the nostrils inevitably cause the asphyxiation of the one who uses it. Thus, the difference with the "Flow restriction and filtering device nasal ventilator to prevent the entry of allergenic substances and strengthening of inspiratory musculature. "

Structured occlusive dressing ES2229254T3: This invention relates to a structured wound dressing that it stays in place and does not slip, but it has a feeling similar to an ointment. The invention also relates to the strips adhesives comprising the aforementioned dressing. This invention refers to a composition containing a base of hydrophobic solvent and a combination of polymers that create a structured occlusive dressing that has a high viscosity and a ointment-like feeling Such an invention differs greatly measure of "Flow restriction and filtering device nasal ventilator to prevent the entry of allergenic substances and strengthening the inspiratory musculature, "not only because in case of being located in the nostrils and used as inspiratory muscle strengthening system or as filtering device, would cause the choking of the subject that uses, but also for its different composition and structure of the materials used, such as the hydrophobic solvent and a combination of polymers without the ability to filter the air inspired.

Inspiratory muscle training device with variable loading WO 2000/024476: It consists of a training device of inspiratory musculature with variable load. The device is placed in the mouth and the subject has to make inspirations and mouth exhalations through a mouthpiece attached to a tube that by means of a regulator arranged in its base that allows changing the air passage resistance. The physiological principle and Results obtained are the same as with the "Device restriction and filtration of nasal ventilatory flow to prevent entry of allergenic substances and strengthening of inspiratory musculature ", the training of the musculature inspiratory, but in this case, said device presents the following drawbacks:

-

Perform the inspiratory exercise for the Mouth and accurate inspiratory mouthpiece cleaning. "Device of restriction and filtration of the nasal ventilatory flow to prevent the entry of allergenic substances and strengthening of Inspiratory musculature "is disposable and the respiratory cycle it is correctly physiological, since it makes inspirations nasal and oral exhalations.

-

It is not compatible with field training and should be used in static positions "Restriction and filtering device of nasal ventilatory flow to prevent the entry of substances allergens and strengthening of inspiratory muscles " allows its use anywhere, be it a gym, at home, in a hospital, on a running track, or a golf course. Likewise form, allows you to develop your daily life activities by at the same time that it enhances the inspiratory musculature.

-

Do not allows actions such as talking, hydrating during training or eat. "Flow restriction and filtering device nasal ventilator to prevent the entry of allergenic substances and strengthening the inspiratory muscles "allows eating or Drink while using.

"Restriction and filtering device of nasal ventilatory flow to prevent the entry of substances allergens and strengthening of inspiratory muscles ", for its simplicity, ease of use and transport it has many advantages over other expensive instruments and devices that also They must be used in static situations. The present invention allows users to develop their daily life activities or sports while enhancing the muscles Inspiratory

Explanation of the invention.

"Restriction and filtering device of nasal ventilatory flow to prevent the entry of substances allergens and strengthening of inspiratory muscles " It is composed, on its upper face and as a first layer, by a strip of hypoallergenic fabric (a) which, depending on the porosity the tissue will be the one that hinders, to a greater or lesser extent, the inspired air flow. A second filter layer (d) of tissue non-woven, through which allergenic particles are retained and pollutants inspired by the respiratory cycle. So that, while the layer (a) can be modified for the manufacture of different levels of ventilation flow restriction, layer (d) Allows filtration of allergenic substances such as pollen. By the reverse and in the two outer thirds of the restriction strip of the ventilatory flow, contains adhesive (b) for its attachment in the nose (c). In the medial third there is a filter tissue (d) that allows to retain allergic particles and contaminants. Saying porous tissue also allows the incorporation of substances pharmacological and / or deodorizing, by impregnating the tissue, that improves the state of health or well-being of the users. Finally, one last layer of plastic material (e) and the corresponding packaging and sterilization to protect the device until it will be used by the subject.

Modifying the size and shape of the "Device of restriction and filtration of the nasal ventilatory flow to prevent the entry of allergenic substances and strengthening of inspiratory musculature ", allows it to adapt to different ages, sizes and flow restriction capacity.

Modifying the device size is possible leave free spaces in the nostril entrances of such that a greater air inlet capacity is allowed and thus being able to manufacture different levels of flow restriction ventilatory On this occasion only the air flowing to through the device

"Restriction and filtering device of nasal ventilatory flow to prevent the entry of substances allergens and strengthening of inspiratory muscles "se placed under the nostrils, reducing flow and / or filtering The entrance of the inspired air. So, depending on the characteristics of the fabric used in manufacturing, density and size of the pores that comprise it, several can be made types of restriction devices and air flow filtering. In function of the subject's physical level and his training status a device will be recommended to achieve the greatest benefits in improving the strength of inspiratory muscles.

The device differs from those explained Previously basically in 5 aspects:

First: Your goal is to strengthen those muscles involved in breathing, used during realization of daily activities, aerobic training and even during rest.

Second: It allows to regulate the air intake, in function of the porosity of the strip of cloth used, being able to adapt therefore to the user's physical requirements in that moment, this being without a doubt its biggest advantage.

Third: Add an extra load to training of aerobic capacity, therefore it is specially designed for athletes who want to use a complement to their resistance training

Fourth: Allows inspired air filtering during the respiratory process so it is very useful for those people who live in places with a high level of pollution atmospheric or allergic diseases, by enabling filtering of pollutants or allergens.

Fifth: It allows incorporating, in the layer of filtering, pharmacological substances or deodorizers that improve the health status or welfare of users.
