Description

{RESPIRATORY MEASURING AND TRAINING COMBINED DEVICE}

The present invention relates to a combined breathing measurement and training device, and more specifically, to a combined breathing measurement and training device developed to measure breathing data through expiration among the expiration and inspiration that constitute human breathing, and to train respiratory muscles through inspiration.

Various programs are applied to improve lung function for patients with chronic obstructive pulmonary disease (COPD) and patients who have undergone lung resection surgery. Among these, drug-based lung function treatment methods can temporarily improve lung function, but their effects are limited and side effects due to excessive drug use may occur. Therefore, respiratory muscle training methods that improve lung function have recently been gaining attention.

Respiratory muscle training methods are gaining attention not only for patients with lung disease mentioned above, but also as a program for managing the health of modern people who do not get enough aerobic exercise. In other words, research results are being published that if you consistently do respiratory muscle training, you can lower blood pressure, strengthen the muscles of the lungs and heart, and improve brain cognitive ability. Respiratory muscle training methods are a method that strengthens the muscles used for inhalation by making the process of inhaling difficult through a portable device that restricts airflow.

Domestic patent registration No. 2326251 (Title of invention: Smart vital capacity training system, Registration announcement date: 2021.12.01) discloses a system that measures respiratory data by inhaling and exhaling air using a mouthpiece according to inspiration and expiration, and measures the user's forced vital capacity (FVC) using this respiratory data to enable training. However, according to this system, a portable device that measures respiratory data is not equipped with a respiratory training function, so respiratory muscle training is simply performed through an app provided through a display device.

Korean Patent Publication No. 2021-0013243 (Title: Respiratory training device and method and system for providing respiratory training using the same, Publication date: 2021.08.10) discloses a respiratory training device including a main body having a flow path formed inside so that air generated by the user's breathing is introduced and moved, a sensor part that senses exhalation or inhalation according to the user's breathing, and a mouth piece that is detachably coupled to the opening part, has one or more air exhaust holes formed in a distribution tube formed by extending downward, and is coupled so that the number of air exhaust holes exposed to the outside can be adjusted. This respiratory training device is configured to intermittently control the adjustment of a stage that makes it difficult to inhale depending on the state of the user's lung function only by exposing the number of air exhaust holes.

Therefore, in order to perform more effective respiratory muscle training, it is necessary to develop a device that can perform respiration measurement and training with a single portable device, as well as continuously adjust the difficulty of inhalation during respiratory muscle training.

In this application, it should be understood that terms such as “comprises” or “have” are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but do not exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

Hereinafter, a respiratory measurement and training device according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

Figures 1 and 2 are perspective views of a combined breathing measurement and training device according to one embodiment of the present invention. The combined breathing measurement and training device (100) largely includes a main body (300) including components necessary for performing breathing measurement and training, and a handle part (200) detachably coupled to the lower end of the main body (300).

The handle part (200) may have a built-in controller (not shown) that processes respiration-related data input from a sensor mounted on the main body part (300) and a battery (not shown) that supplies power to the sensor and controller. The handle part (200) is configured in a vertically long bar shape, and the cross-section may be configured in a cylindrical or polygonal shape so that the user can easily hold it by hand. A control button (210) used by the user to operate the device and a display (220) that displays the operating status of the device may be additionally provided on the front side of the handle part (200). In addition, a separation button (230) used when separating from the main body part (300) may be provided on the rear side of the handle part (200).

In this way, since the handle part (200) is configured to have the basic components necessary for control built in and the main body part (300) detachable as needed, not only the portable respiratory muscle training module according to the present invention, but also various medical modules, such as a body temperature measurement module, a blood sugar measurement module, a rhinitis treatment module, a nebulizer module, an ultrasound treatment module, etc., can be conveniently attached and used.

The above main body (300) includes various components that enable measuring respiratory data through expiration among the expiration and inspiration that constitute human breathing and training respiratory muscles through inspiration.

That is, the main body (300) includes a main body (310) in which a flow pipe (314) through which the user's breathing air passes is formed, and a sensor for measuring the pressure of air through exhaled air and the gas component contained in the exhaled air is mounted inside the flow pipe (314), a mouth piece (320) that is detachably inserted into the front of the flow pipe (314) of the main body (310) and that the user can bite and breathe through, a connecting pipe (330) that is connected to the rear of the flow pipe (314) of the main body (310) so as to be connected, and includes an air distribution valve that intermittently opens and closes the air distribution inside, and a rear-mounted pipe (340) that is connected to the rear of the connecting pipe (330) so as to be connected, has an air vent hole formed through which air is introduced from the outside, and has an inhalation difficulty control module mounted inside so as to be able to move back and forth into the interior of the connecting pipe (330).

Referring to FIGS. 3 to 5, the components of the main body (300) of the respiration measurement and training combined device according to one embodiment of the present invention will be described in more detail. FIG. 3 is an exploded perspective view of the respiration measurement and training combined device, FIG. 4 is a cross-sectional view showing the main components of the respiration measurement and training combined device, and FIG. 5 is an enlarged cross-sectional view of part “A” in FIG. 4.

As described above, the main body (300) is largely composed of a main body (310), a mouth piece (320), a connecting tube (330), and a rear mounting tube (340), and an inhalation difficulty adjustment module for adjusting inhalation pressure to enable respiratory muscle training is installed inside the connecting tube (330) and the rear mounting tube (340).

The main body (310) above is formed with a flow pipe (314) extending horizontally on the upper part of the body. This flow pipe (314) forms a path through which breathing air passes when the user breathes. Various types of sensors capable of measuring breathing data are mounted inside this flow pipe (314). The lower part of the main body (310) is connected to the controller of the handle part (200) through a connector (311) connected to the sensor.

According to one embodiment of the present invention, a ketone sensor (312) capable of measuring the ketone concentration in exhaled air and a pressure sensor (313) capable of measuring the gas pressure of exhaled air may be installed, as shown in FIG. 4.

In one embodiment of the present invention, only a ketone sensor and a pressure sensor are used as examples as sensors for measuring respiratory data, but the technical idea of the present invention is not limited thereto, and may also include various sensors that measure volatile sulfur compounds such as carbon dioxide, carbon monoxide, and hydrogen sulfide, and volatile organic compounds such as ethanol contained in exhaled air.

The concentration of ketones (more precisely, the concentration of acetone) in the exhaled air measured by the above ketone sensor (312) is related to the rate of decomposition of body fat in the human body, and thus, a method of measuring the concentration of ketones in the exhaled air has recently been used as a method of checking the progress of a diet. The energy sources of the human body are carbohydrates, proteins, and fats in that order, and when there is a shortage of carbohydrates or proteins in the body, fats are decomposed to obtain energy. At this time, when fats are decomposed, organic compounds called ketones are generated, and a state in which a large amount of ketones exist in the human body and can be used as an energy source is called ketosis. In the ketosis state, body fat continues to be decomposed, resulting in weight loss.

There are two ways to measure ketones: by drawing blood and directly measuring the concentration of ketones produced in the blood, and by indirectly measuring the concentration of ketones using the level of acetone measured through breath. The breath measurement of the present invention uses the latter method. The relationship between the level of acetone, the concentration of ketones, and the rate of body fat decomposition is as described in Table 1 below.

Acetone concentration
(ppm) Ketone concentration
(mmol/L) Body fat decomposition rate 1.0 ~ 1.9 0.1 ~ 0.2 No change in body fat 2.0 ~ 3.9 0.3 ~ 0.4 A state in which mild body fat decomposition occurs at an average rate of about 2g per hour. 4 ~ 9.9 0.5 ~ 1 A state in which intermediate body fat decomposition occurs at an average rate of about 5g per hour. 10 ~ 39 1.5 ~ 3.5 A state in which strong body fat decomposition occurs at an average rate of about 10g per hour. 4 ~ 6 There is no additional body fat breakdown, but it is a stage where health promotion effects such as cancer prevention occur.

The pressure sensor (313) measures the pressure of gas generated during exhalation. Respiration refers to the process of inhaling oxygen from the outside into the body, transporting it to cells, and exhaling carbon dioxide generated after the cells consume oxygen and perform metabolism. At this time, taking in air from the outside into the lung cells is called inspiration, and since this is driven by contraction of the external intercostal muscles, etc., it is an active movement. Exhaling air inside the lung cells where gas exchange is complete is called exhalation, and since this is a process in which the muscles that were contracted by inspiration relax, it is a passive movement.

In the case of inhalation, since it is an active exercise process using respiratory muscles, the breathing training of the present invention allows for training the respiratory muscles used in the inhalation process to increase lung capacity. In the case of exhalation, since it is a process of expelling air to the outside after gas exchange in the lungs, the air exhaled during the exhalation process contains various components, and by analyzing this exhaled air, the health status of the human body, especially the respiratory system, can be checked.

The most basic respiratory data that can be obtained during the exhalation process is the lung capacity, which is confirmed through the pressure of exhaled air. The most commonly used diagnostic variable in spirometry is the forced vital capacity (FVC), which means the total amount of air that can be forcefully exhaled after maximum inspiration, and is usually 4.0 or higher for men and 2.8 or higher for women.

There are a number of methods for measuring lung capacity, including a method of recording mechanical changes on paper while storing air during the exhalation and inhalation process in a cylinder, etc. (Volume Spirometer), and a method of measuring airflow and volume by converting changes in air speed during exhalation and inhalation into electrical signals using changes in air pressure or other sensors (Flow Spirometer). The respiration measurement of the present invention uses the latter method. In one embodiment of the present invention, a method of calculating lung capacity by measuring changes in pressure of exhaled air is adopted, but the technical idea of the present invention is not limited thereto, and may include various methods, such as measuring the speed of exhaled air or measuring magnetic force according to changes in air pressure.

The above-described mouth piece (320) is detachably inserted into the front of the flow tube (314) of the main body (310) so that a user can bite it and breathe. It is preferable that the mouth piece (320) be detachably installed in the main body (310) so that multiple users can use their own mouth pieces (320). In FIG. 3, the mouth piece (320) is illustrated as having a hollow cylindrical shape, but it may be made in various shapes so that a user can bite it in their mouth. When the mouth piece (320) is inserted into the flow tube (314) of the main body (310), the mouth piece (320) and the flow tube (314) of the main body (310) communicate with each other to form a single flow tube through which breathing air circulates.

The above connecting pipe (330) is connected to the rear of the main body (310) so as to be in communication with the flow pipe (314), and an air circulation valve that intermittently opens and closes the air circulation is formed inside. As illustrated in FIG. 5, the air circulation valve includes an open penetration portion (332) having a first diameter (d1) on the inner surface of the connecting pipe, and a closed penetration portion (331) that is continuously formed at the rear of the open penetration portion (332) and has a second diameter (d2) smaller than the first diameter (d1). The open penetration portion (332) and the closed penetration portion (331) having two different diameters serve as a valve that controls the inflow of external air into the flow pipe (314) of the main body (310) in conjunction with the forward and backward movement of the slider (350) of the intake difficulty control module.

When the user performs inhalation to inhale air for breathing training, negative pressure is applied inside the flow tube (314) of the main body (310), causing the slider (350) to advance forward. At this time, the O-ring (380) mounted on the tip of the slider (350) rubs against the inner surface of the closed penetration portion (331), generating resistance. In this process, respiratory muscle strengthening training is performed. When the slider (350) advances a certain distance (L) or more, the air distribution valve opens, allowing outside air to flow into the flow tube (314) of the main body (310), and as a result, the negative pressure is released, thereby ending the respiratory muscle strengthening training. When the user stops inhaling, the slider (350) returns to its original position by the restoring force of the restoration spring (380). The operational relationship of the device during this respiratory muscle training process through inhalation will be described in detail later with reference to FIGS. 9 and 10.

The above rear-mounted pipe (340) is connected to the rear of the connecting pipe (330) so as to be in communication with it, and an air vent hole (343) is formed through which air is drawn in from the outside, and an intake difficulty adjustment module is mounted inside so that it can move forward and backward to the inside of the connecting pipe (330).

The above-described inhalation difficulty control module includes a slider (350) that selectively releases inhalation pressure by opening and closing an air distribution valve provided inside a connecting tube (330) while moving back and forth during the user's inhalation process, a restoration spring (370) that returns the slider (350) to its original position when the inhalation pressure is released, and a control member (360) that continuously controls the degree of compression or extension of the restoration spring (370) to control the respiratory muscle training stage.

In addition, when the front end of the slider (350) passes through the closed penetration portion (332), it comes into close contact with the inner surface of the closed penetration portion (332) to block external air from flowing from the rear mounting pipe (340) to the flow pipe (314) of the main body, and when the front end of the slider (350) passes through the open penetration portion (331), it is separated from the inner surface of the open penetration portion (331) to allow external air from the rear mounting pipe (340) to flow to the flow pipe (314) of the main body.

At this time, the slider (350) is equipped with an O-ring (380) at its tip to increase the sealing force with the inner surface of the closed penetration portion (332). The O-ring (380) not only increases the sealing force with the closed penetration portion (332) to improve the airtightness when the air distribution valve is closed, but also increases the frictional force with the closed penetration portion (332) to increase the resistance when the slider (350) moves forward by inhalation during respiratory muscle training.

The above slider (350) is formed as a cylinder having a certain length, and a spring mounting portion that is fitted with the restoration spring is provided on the front outer surface of the cylinder, and a spring adjusting portion (351) that has screw threads formed on the outer surface of the cylinder so that the adjusting member can be rotatably coupled is provided on the rear outer surface of the cylinder.

At this time, the restoration spring (370) is mounted at its front end on the first fixed step (333) formed on the inner surface of the connection tube (330) while the spring mounting portion of the slider (350) is fitted, and its rear end is mounted by the second fixed step (361) of the adjustment member (360). As a result, the restoration spring (370) is compressed or extended between the connection tube (330) and the adjustment member (360) when the adjustment member (360) rotates forward and backward along the screw thread formed on the spring adjustment portion (351) of the slider (350).

The above restoration spring (370) changes the magnitude of the force that must be applied to deform it when it is compressed or extended, compared to a state in which it is not elastically biased, i.e., a state in which its original length is maintained. For example, in order to extend the length of the restoration spring (370) in a state in which it is compressed more than its original length, a greater force is required than in order to extend the length in the original length state in which it is not elastically biased. Conversely, in order to further extend the length of the restoration spring (370) in a state in which it is extended more than its original length, a smaller force is sufficient than in order to extend the length in the non-elastically biased state.

By using this principle of change in spring elasticity, the intensity of the respiratory muscle training stage can be appropriately adjusted by adjusting the length of the restoration spring (370) mounted on the slider (350). The adjustment member (360) is formed in a hollow cylindrical shape and is inserted into the slider (350) in a form that covers the restoration spring (370) to which the spring mounting portion of the slider (350) is fitted.

One of the characteristic technical configurations of the present invention is that the elasticity of the restoration spring (370) can be continuously adjusted, thereby enabling more effective respiratory muscle training by continuously controlling the inhalation pressure during respiratory muscle training. This technical effect is achieved by allowing the mounting length of the restoration spring (370) to be continuously changed by the adjustment member (360).

The elasticity adjustment step of the restoration spring (370) is described in detail with reference to FIGS. 6 to 8.

First, as shown in Fig. 6, when the adjusting member (360) is rotated along the screw thread formed in the spring adjusting member (351) of the slider (350) and moved to the point furthest from the air distribution valve of the connecting pipe (330), the restoring spring (370) is mounted to its original length without being elastically biased. At this time, the elastic restoring force of the restoring spring (370) is the lowest, so that the easiest stage of respiratory muscle training can be performed.

As shown in Fig. 7, when the adjustment member (360) is rotated along the screw thread formed in the spring adjustment member (351) of the slider (350) and moved to the middle point from the air distribution valve of the connecting pipe (330), the restoration spring (370) is mounted with a partially compressed length. At this time, the elastic restoring force of the restoration spring (370) is intermediate, so that intermediate-stage respiratory muscle training can be performed.

Lastly, as shown in Fig. 8, when the adjusting member (360) is rotated along the screw thread formed in the spring adjusting member (351) of the slider (350) and moved to the closest point from the air distribution valve of the connecting pipe (330), the restoring spring (370) is configured to be mounted at the most compressed length. At this time, the elastic restoring force of the restoring spring (370) is the highest, so that the most difficult stage of respiratory muscle training can be performed.

Referring to FIGS. 9 and 10, the operating state of the device in the respiratory muscle training process through inspiration according to the present invention is described in detail.

Fig. 9 is a drawing showing the state before inhalation of the combined device for respiration measurement and training. Currently, the control member (360) is moved to the closest point from the air distribution valve of the connecting pipe (330) as shown in Fig. 8, so that the elastic restoring force of the restoration spring (370) is the highest, so that the most difficult stage of respiratory muscle training can be performed. In this state, if the user has not yet inhaled for respiratory muscle training, the restoration spring (370) is maintained in the maximum compressed state, and the O-ring (380) mounted on the tip of the slider (350) is maintained in a state of close contact with the inner surface of the closed penetration portion (331).

When the user starts to inhale, negative pressure is generated in the fluid pipe (314) of the main body (310), and the O-ring (380) mounted on the tip of the slider (350) moves forward while rubbing against the inner surface of the closed penetration portion (331). At this time, the suction force advances the slider (350) forward while elastically stretching the restoration spring (370) into which the slider (350) is inserted. Since the restoration spring (370) is in a maximally compressed state, a large suction force is required to stretch it, and as a result, high-intensity respiratory muscle training becomes possible.

Fig. 10 is a drawing showing the state after inhalation of the device for measuring and training respiration. When the user continues to inhale, the O-ring (380) mounted on the tip of the slider (350) passes the closed penetration portion (331) and reaches the open penetration portion (332) having a larger diameter than the closed penetration portion. As a result, a gap is created between the O-ring (380) mounted on the tip of the slider (350) and the open penetration portion (332), and through this, external air introduced through the air vent hole (343) of the rear-mounted pipe (340) is introduced to the flow pipe (314) of the main body (310), thereby releasing the negative pressure caused by inhalation. Thereafter, the slider (350) returns to the position of Fig. 9 by the restoring force of the restoring spring (370). As this process is repeated, respiratory muscle training using the device is performed.

The technical features disclosed in each embodiment of the present invention are not limited to that embodiment, and, unless they are mutually incompatible, the technical features disclosed in each embodiment may be combined and applied to different embodiments.

Therefore, each embodiment will be described with a focus on each technical feature, but unless each technical feature is incompatible with each other, it can be applied in combination with each other. The present invention is not limited to the above-described embodiment and the attached drawings, and various modifications and variations are possible from the viewpoint of a person having ordinary knowledge in the field to which the present invention pertains.
