Description

Equipment for customized SOVTE condition analysis and customized SOVTE condition analysis method using the same {Equipment for customized SOVTE condition analysis and customized SOVTE condition analysis method using the same}

The present invention relates to a connection adapter that enables an aerodynamic test while training using a SOVTE tool, equipment for custom SOVTE condition analysis to which it is applied, and a custom SOVTE condition analysis method using the same.

Aerodynamics tests are being performed for the diagnosis and evaluation of voice disorders in clinical practice. The aerodynamics test measures the subglottal pressure (Ps), which is the pressure below the vocal cords, and the mean airflow rate (MFR), which is the flow of air passing between the glottis, to predict the efficiency of expiration when producing voice. is to do Various devices can be used for this, but recently, a phonatory aerodynamic system (Model 6600, KayPentax, NJ, USA; hereinafter PAS; see non-patent literature) has been widely used.

The principle of the PAS test is as follows. When the mask is fully adhered to the mouth and nose and vocalization is performed, the expiratory flow rate or subglottic pressure information is obtained from the airflow and pressure data according to vocalization. From these basic variable values, information such as aerodynamic power (APOW), aerodynamic resistance (ARES), and aerodynamic efficiency (AEFF) can be calculated. Photos of PAS and PAS inspection are attached to Figure 1a. Through this aerodynamics test, it is possible to objectively evaluate the pronunciation and voice characteristics of users, including patients.

On the other hand, there are not a few cases in which people suffer from congenital or diseased or injured voice disorders, that is, they feel fatigue and pain in the neck due to vocalization, and suffer from discomfort that makes accurate pronunciation difficult. It is known that laryngeal massage and semi-occluded vocal tract exercises (SOVTE) are useful for the treatment or improvement of such dysphonia. SOVTE is a vocal cord function improvement training that induces back pressure by vocalizing while partially closing the vocal cords, prevents over-contact of the vocal cords due to this back pressure, and maintains an ideal contact state for efficient vocalization. .

Among the various SOVTE techniques, a convenient method is to immerse one end of the tube in the water of a water bottle and put the other end of the tube in your mouth, or wear a mask connected to the other end as shown in the drawing (see Fig. 1b) and perform vocal training.

At this time, the conditions of the SOVTE training device (tube length, diameter, container size, amount of water contained in the container, etc.) should be appropriately adjusted according to the user's characteristics. In the past, SOVTE's practice environment and practice results were objectively measured The reality is that the conditions are determined sensibly and the performance is judged based on the experience of experts.

There has been no attempt to confirm and verify conventional SOVTE training through aerodynamics testing, and to provide objective, customized SOVTE training conditions.

Patent Publication 10-2021-0068268 (Smart Breed) posts a breathing training device (see FIG. 1c) capable of breathing training to increase cardiopulmonary power and maximum oxygen intake. However, according to this, although there is a side effect of 'strengthening the vocal cords to help with vocal practice', it is not for the treatment or improvement of dysphonia, nor is it intended to measure physical characteristics in the vocalization process.

US 10460749 B1 (Voice therapy and vocal training device) discloses a modified SOVTE training device (see FIG. 1d). However, this is only a kind of SOVTE training device and has no concept of aerodynamics inspection.

DE 10-2017-000570 B3 (Method and training tool for adjusting the vocal tract for voice, singing and playing of wind instruments) is pronounced through a tube, the pronunciation is electrically signaled through a microphone, and the sound wave field is analyzed in the device body It relates to a device for airway control training (see FIG. 1e). However, this also does not have the concept of aerodynamics inspection for objectification of SOVTE training.

(1) 1st invention

As described above, the present invention relates to an adapter 10 connected to a SOVTE device for SOVTE and an aerodynamic inspection device 30.

In a conventional SOVTE device (see FIG. 1B), a container 21 containing liquid, an inner end (distal end) is submerged in the liquid contained in the container 21 and an exposed end (proximal end) exposed to the outside. It is a device for semi-occlusive strength training including a tube through which air is introduced by the user's vocalization. At this time, a so-called airtight breathing mask 23 (rescue mask, respiratory mask; respirator mask, resuscitation mask; resuscitation mask, pocket mask; pocket mask, CPR mask, etc.) that seals and covers the user's nose and mouth is also called, hereinafter simply ' breathing ' A mask 23 ' ) may be coupled to the exposed end of the tube as in FIG. 1B. At this time, the breathing mask 23 may be equipped with a ventilation valve that enables intake and disables exhaust, as shown in FIG. 1B.

As shown in FIG. 1A, a typical aerodynamic testing device 30 has a first inlet 31 (intra-oral tube connection) and a second inlet 32 (airflow) through which air is introduced by a user's voice. tube), and measures and calculates variable values including airflow and pressure information according to vocalization. Depending on the type and function of the aerodynamics inspection device 30, the air introduced through the first inlet 31 and the second inlet 32 may be branched in various ways and used for obtaining various types of data.

The adapter 10 according to the present invention has two characteristics as follows.

① It is interposed in the middle of the tube of the SOVTE device or replaces the tube to function as a passage for air circulation and a stopper 14 that is sealedly coupled to the inlet of the container 21.

The fact that the adapter 10 is 'interposed in the middle of the tube' means that the adapter 10 is usually present between the tubes, that is, a normal tube is mounted at the front and rear ends of the adapter 10. The adapter 10 'replaces the tube' means that the adapter 10 itself functions as a tube without a tube attached to the rear end of the adapter 10 or without a tube at both the front and rear ends of the adapter 10. The fact that the adapter 10 'functions as a stopper 14 sealedly coupled to the inlet of the container 21' means that the air introduced into the container 21 is discharged through a predetermined flow path without being directly discharged to the outside. that it is structured to This will be explained in detail later.

② An inlet 11 into which air flows from the exposed end of the tube, a first outlet 12 that diverges a part of the air flowing into the inlet 11 and sends it to the first inlet 31 , and the end A supply passage 13 that is hermetically coupled to the container 21 and diverts the rest of the air flowing into the inlet 11 to the container 21, and the air discharged from the container 21 to the first It is a structure including a second outlet 15 sending to the second inlet 32. 2a to 2c show three exemplary cross-sectional views of the adapter 10 according to the present invention, and FIG. 2d shows a photograph of an example of manufacturing the adapter 10 according to the present invention. In FIGS. 2A to 2C, the illustration of the connection tube 16 and the inner tube 22 in FIG. 2D is omitted. In FIGS. 2A to 2D, the container 21 and the water are also omitted, but the pictures that are not omitted are attached as other drawings and will be described later.

2a to 2c are examples of structural changes of the inlet 11, which are topologically the same and have similar functions.

According to the adapter 10 according to the present invention, when air flows in according to the user's vocalization from the exposed end of the tube, the inlet 11 - the first outlet 12 - the connection tube 16 - the first inlet 31 ) Passage (indicated by a red arrow) and inlet 11 - supply passage 13 - stopper 14 - container tube 22 - (container 21) - stopper 14 - second inlet It is branched into the passage (32) (indicated by the blue arrow) and delivered to the aerodynamic inspection device 30. At this time, since water is contained in the container 21 and the distal end of the supply passage 13 (which may be extended as a separate tube 22 as shown in FIG. 2d) is submerged in water, air passes through the water (described below). Mention of the water in the container 21 is omitted for simplicity).

Although a tube that the user simply practices while holding in his mouth may be connected to the inlet 11 side of the adapter 10 according to the present invention, the proximal end of the tube or the inlet 11 of the adapter 10 without a tube is sealed. A breathing mask 23 may also be mounted directly. Hereinafter, the accompanying drawings (FIG. 4a, 4b) show an example in which the airtight respirator 23 is directly mounted to the inlet 11 of the adapter 10 without a tube.

On the other hand, as described above, as the SOVTE device can be equipped with an airtight respirator 23, the adapter 10 according to the present invention also has the exposed end (proximal end) of the tube or without the tube for user convenience and accuracy of inspection. An airtight respirator 23 may be directly coupled to the inlet 11 (see FIGS. 4a and 4b). When the breathing mask 23 is coupled, the user uses the breathing mask 23 in close contact with the face without biting the proximal end of the tube in the mouth. On the other hand, as shown in FIG. 1A, the proximal end (left yellow arrow in the drawing) connected to the first inlet 31 of the conventional aerodynamic inspection device 30 is located in the mouth of the wearer of the respiratory mask 23. Therefore, when the respirator 23 is coupled to the adapter 10 according to the present invention, one end (distal end) is connected to the first outlet 12, and the exposed end (proximal end) is the respirator It is preferable to add an intraoral tube (not shown) protruding toward the face portion of (23). 2c may be a suitable adapter 10 structure.

It is equipment for analyzing SOVTE conditions, characterized in that it is connected to the second inlet 32 of ). That is, the present invention is equipment in which the above-mentioned adapter 10 is coupled to a conventional SOVTE device, or a SOVTE device is combined with an aerodynamic inspection device 30 while replacing a part of the configuration of a conventional SOVTE device. Figure 3 shows a front (viewed from the proximal side) and a picture viewed from the left of an exemplary production example of the equipment for SOVTE condition analysis according to the simplest of the present invention (in the picture, the container 21 is not filled with water) ). The user performs SOVTE training by holding the inlet 11 (proximal end) of the adapter 10 directly or with a predetermined intermediary part attached to the mouth. Then, the air by the user's vocalization is branched into two branches by the structure of the adapter 10 as described above, and each 'inlet 11 ~ first outlet 12 ~ first inlet 31 of the inspection device 30 )' passage, 'inlet 11 - supply passage 13 - stopper 14 - (container 21) - stopper 14 - second inlet 32 of inspection device 30' It is delivered to the aerodynamic inspection device 30 through the passage of the. As a result, the SOVTE training and the corresponding aerodynamics test are conducted simultaneously.

As described above, in the equipment for analyzing the SOVTE condition, an airtight respirator 23 may be coupled to the exposed end of the tube or the inlet 11. In the form where the breathing mask 23 is directly coupled to the inlet 11, a picture taken from the distal side in a state not coupled to the aerodynamic inspection device 30 is shown in FIG. 4A, equipment for analyzing SOVTE conditions in the coupled state Pictures taken from various angles of an example of are attached to FIG. 4B.

The method of using the equipment for analyzing the SOVTE condition or the addition of an intraoral tube (not shown) is as described above.

With the equipment for analyzing SOVTE conditions of the present invention as described above, it is possible to simultaneously conduct an aerodynamics test in a SOVTE training situation. Accordingly, it is possible to increase the usability of the conventional aerodynamic inspection device 30 and secure objective data for the SOVTE.
