Description

Respiratory function recovery device and respiratory function recovery system

[0001] The present invention relates to a respiratory function recovery device and a respiratory function recovery system for recovering the function of muscles in the region from the mouth to the pharynx, and in particular for overcoming respiratory disorders such as sleep apnea through functional recovery.

[0002] Respiratory disorders such as sleep apnea are known to have adverse health effects.

[0003] However, because the base of the tongue unconsciously blocks the airway during apnea, it is currently quite difficult to consciously improve this condition. The tongue, oropharynx, and hypopharyngeal muscles work in coordination to move the tongue, and the only way to restore function is to actually move these muscles. Other muscles that also work include the posterior belly of the digastric muscle, anterior belly of the digastric muscle, omohyoid muscle, sternocleidomastoid muscle, clavicular head, masseter muscle, levator scapulae muscle, thyrohyoid muscle, sternothyroid muscle, and scalene muscles.

[0004] Therefore, an object of the present invention is to provide a device or the like that can efficiently restore the functions of various muscles involved in respiratory function.

[0005] Prior to solving the above problem, the inventor conceived the idea of ​​passing a low-frequency current through the jaw area from the body surface or externally to contract the throat muscles (particularly the digastric muscles (anterior and posterior bellies)) and thereby restore and strengthen muscle strength. However, when passing a low-frequency current through the jaw area from the body surface, there was a possibility that the effect of the low-frequency current would only extend to the periphery of the body surface. Therefore, the inventor conceived the idea that passing a low-frequency current through the tongue inside the mouth from the tongue muscles to the throat muscles would contract these muscles and restore and / or strengthen muscle strength.

[0006] The respiratory function recovery device of the present invention comprises: a jaw electrode; a tongue interaction mechanism configured to maintain an electrical connection between the tongue electrode and the subject's tongue; a jaw interaction mechanism configured to maintain an electrical connection between the jaw electrode and the subject's jaw; and an EMS signal generator configured to transmit an EMS signal between the tongue electrode and the jaw electrode.

[0007] In this respiratory function recovery device, the tongue interaction mechanism maintains an electrical connection between the tongue of a subject (such as a human or animal) and the tongue conductor, and the jaw interaction mechanism maintains an electrical connection between the subject's jaw and the jaw conductor. "Electrical connection" refers to a state in which an EMS signal or EMS current can be transmitted or passed through the conductor to the subject. "EMS" stands for Electrical Muscle Stimulation. This ensures that the EMS signal or EMS current generated by the EMS signal generator is transmitted or passed between the subject's tongue and jaw through the tongue conductor and the jaw conductor, respectively. The EMS signal contracts various muscles between the tongue and jaw involved in breathing, thereby restoring or maintaining the strength or function of those muscles (the subject's swallowing strength).

[0008] In the respiratory function recovery device having the above configuration, it is preferable that the tongue electrodes include a first tongue electrode and a second tongue electrode, and the jaw electrodes include a first jaw electrode and a second jaw electrode, and the EMS signal generator is configured to generate a first EMS signal and a second EMS signal having different frequencies, transmit the first EMS signal between the first tongue electrode and the first jaw electrode, and transmit the second EMS signal between the second tongue electrode and the second jaw electrode.

[0009] According to the respiratory function recovery device having this configuration, a first EMS signal passed between the first tongue conductor and the first jaw conductor and a second EMS signal passed between the second tongue conductor and the second jaw conductor, which has a different frequency from the first EMS signal, are mutually interfered with, thereby providing interference wave stimulation to the jaw muscles. In particular, a pulse current can be passed through muscles located deep in the jaw. The tongue muscles are also stimulated with interference waves.

[0010] In the respiratory function recovery device having the above configuration, it is preferable that the jaw interaction mechanism includes a head wrapping member that is wrapped around the head of the subject so as to hang over the jaw of the subject.

[0011] With this respiratory function recovery device, the head wrapping member is wrapped around the subject's head so that it rests on the subject's chin, thereby reliably maintaining the chin electrode in contact with the chin. If the chin electrode is provided displaceably on the head wrapping member, the position of the chin electrode can be finely adjusted according to differences in the subject's head size, etc. The head wrapping member (e.g., a belt or chin supporter) may be provided with a fastener such as a buckle or hook-and-loop fastener.

[0012] In the respiratory function recovery device having the above configuration, it is preferable that the jaw interaction mechanism includes a neck hanging member that is hung around the back of the neck and the jaw of the subject.

[0013] With this respiratory function recovery device, the neck-hanging member (clip or neckband) is hung from the back of the neck to the front, so that the chin electrode provided on the neck-hanging member is kept in contact with the chin. The neck-hanging member has the advantage of being easy to attach and detach from the neck or chin.

[0014] In the respiratory function recovery device having the above configuration, it is preferable that the jaw interaction mechanism includes an adhesive pad configured to be detachably attached to the jaw of the subject.

[0015] With this respiratory function recovery device, the chin electrode can be reliably maintained in contact with the subject's chin (skin) by the adhesive pad. The adhesive pad is detachable from the skin of the chin.

[0016] In the respiratory function recovery device having the above configuration, it is preferable that the jaw interaction mechanism includes a suction cup that can be attached to and detached from the jaw of the subject.

[0017] In the respiratory function recovery device having this configuration, the electrode can be attached to the skin of the throat by a special structure of the surface that comes into contact with the jaw, called a suction cup. The suction cup can be attached to and detached from the skin freely.

[0018] In the respiratory function recovery device having the above configuration, it is preferable that the jaw interaction mechanism comprises a base and a pair of extension parts that branch out from the base and extend so as to sandwich the subject's jaw from the left and right, and that the jaw electrodes are provided on each of the pair of extension parts.

[0019] With this respiratory function recovery device, a pair of extension sections that branch out from a base and extend to sandwich the subject's jaw from the left and right sides are used to reliably maintain the jaw electrodes attached to each of the pair of extension sections in contact with the left and right sides of the jaw. The strength of the contact pressure of the jaw electrodes against the jaw and the contact points of the jaw electrodes with the jaw can be adjusted, for example, by moving the base. If the jaw electrodes are configured as rollers, they can be rolled along the muscles that make up the jaw and make contact. This allows the subject to experience the sensation of training their respiratory function.

[0020] In the respiratory function recovery device having the above configuration, it is preferable that the tongue interaction mechanism includes a tongue depressor.

[0021] According to the respiratory function recovery device having this configuration, a tongue depressor is used, which is a tool for holding down the tongue when examining the oral cavity and / or esophagus, so that the tongue guide can be reliably maintained in contact with the tongue. Generally, a stainless steel tongue depressor that is used while being sterilized is used. A disposable wooden tongue depressor may also be used.

[0022] In the respiratory function recovery device having the above configuration, it is preferable that the tongue interaction mechanism includes a finger cot.

[0023] According to the respiratory function recovery device of this configuration, the use of a finger cot attached to the fingers of the subject or a third party can reliably maintain the tongue guide in contact with the tongue.

[0024] In the respiratory function recovery device having the above configuration, it is preferable that the tongue interaction mechanism has a suction cup that can be attached to and detached from the tongue.

[0025] With this respiratory function recovery device, the suction cup can be easily attached to a tongue wet with saliva, so the tongue guide can be reliably maintained in contact with the subject's tongue. Furthermore, the suction cup can be easily removed from the subject's tongue without any particular difficulty.

[0027] (First embodiment) The respiratory function recovery device as the first embodiment of the present invention shown in Figure 1 comprises a tongue electrode 12, a pair of jaw electrodes 22, a tongue interaction mechanism 11, a jaw interaction mechanism 21, and an EMS signal generator 40.

[0028] As shown in Figures 1 and 2, the tongue interaction mechanism 11 is composed of a tongue depressor. As shown in Figure 2, at least a portion of the tongue depressor is made of a conductive material such as stainless steel, and the tongue conductor 12 is made of this conductive material. An electrode made of conductive polyester, which is less likely to cause a tingling sensation, may be used as the tongue conductor 12. The tongue depressor may be made of an insulating material such as wood or synthetic resin, and a portion of the insulating material may be made of a conductive material. The tongue conductor 12 may be made of a metal clip and may be detachably attached to the tongue depressor. When the tongue depressor is pressed against the tongue T of the subject S, an electrical connection between the tongue conductor 12 and the tongue T is maintained. The shape and size of the tongue depressor may be adjusted so that when the subject S holds the tongue depressor in his or her mouth, an electrical connection between the tongue conductor 12 and the tongue T is maintained.

[0029] As shown in Figures 1 and 3, the chin interaction mechanism 21 is composed of a chin supporter that is wrapped around the head from the chin C to the top of the head. The chin supporter is made of, for example, leather, natural fibers such as cotton, or synthetic fibers such as polyester. As shown in Figure 3, a male hook-and-loop fastener 2101 and a female hook-and-loop fastener 2102 are provided at each end of the chin supporter. Instead of hook-and-loop fasteners, a connecting mechanism for connecting both ends (or one end and a middle portion) of the chin supporter, such as a buckle, hook or snap button, may be provided. The chin supporter may have strings that can be looped around both ears of the subject like a mask and may be configured to abut against the subject's chin (like a chin mask).

[0030] A pair of approximately rectangular band-shaped chin electrodes 22 are arranged on the surface or inside of the chin supporter, spaced apart in the width direction (short direction) of the belt and extending parallel to the longitudinal direction of the chin supporter. Electrodes made of conductive polyester, which do not cause a tingling sensation to the subject S, may be used as the pair of chin electrodes 22. The number, shape, size, and arrangement of the chin electrodes 22 may be modified in various ways. The chin supporter is wrapped around the head of the subject S and both ends are connected, thereby maintaining an electrical connection between the chin C of the subject S and each of the pair of first chin electrodes 221 and the pair of second chin electrodes 222.

[0031] As shown in FIG. 1 , the EMS signal generator 40 includes a power supply unit 41, a control unit 42, a pulse generator 43, and an output unit 44. The power supply unit 41 is configured to supply power to the control unit 42 and other components. The control unit 42 is configured as a computer, and its arithmetic processing unit (processor) reads necessary software (programs) and data from a storage device (memory) and executes predetermined arithmetic processing based on the data and in accordance with the software. The pulse generator 43 generates a pulse signal and adjusts its period and / or amplitude in response to commands from the control unit 42 to generate an EMS signal as a pseudo-waveform signal. The EMS signal may be, for example, at least one of a low-frequency electrical signal (20-100 Hz), a medium-frequency electrical signal (1000-10,000 Hz), and a high-frequency electrical signal (10,000-20,000 Hz). The output section 44 is connected to the tongue electrode 12 via a terminal 4401 and a conductor L1, and is connected to each of the pair of jaw electrodes 22 via a terminal 4402 and a conductor L2.

[0032] (Effects) With the respiratory function recovery device configured as described above, the tongue interaction mechanism 11 maintains an electrical connection between the tongue T of the subject S (animal such as a human) and the tongue conductor 12, and the jaw interaction mechanism 21 maintains a direct or indirect electrical connection between the jaw C of the subject S and the pair of jaw conductors 22. This ensures that the EMS signal or EMS current generated by the EMS signal generator 40 is reliably transmitted or passed between the tongue T and jaw C of the subject S via the tongue conductor 12 and the pair of jaw conductors 22. The EMS signal causes various muscles between the tongue T and jaw C involved in breathing to contract, thereby restoring or maintaining the strength or function of those muscles (the subject S's muscle strength to swallow).

[0033] The EMS signal can be applied to the tongue T and jaw C while the subject S is watching television or reading, making it possible to restore or train the strength of muscles involved in respiratory function not only at home but also when out and about. When the subject S presses a switch on a remote control for an electrical appliance such as a television, air conditioner, computer, or audio equipment, the control unit 42 detects this via wireless communication between the remote control and the EMS signal generator 40, and in response, an EMS signal may be transmitted between the tongue T and jaw C of the subject S.

[0034] (Second embodiment) A respiratory function recovery device as a second embodiment of the present invention shown in Figure 4 comprises a first tongue conductor 121, a second tongue conductor 122, a pair of first jaw conductors 221, a pair of second jaw conductors 222, a tongue interaction mechanism 11, a jaw interaction mechanism 21, and an EMS signal generator 40. Regarding the second embodiment, differences from the first embodiment will be described, and the same reference numerals will be used for components similar to those in the first embodiment, and descriptions thereof will be omitted where appropriate.

[0035] As shown in Figures 4 and 5, the tongue interaction mechanism 11 is composed of a tongue depressor. As shown in Figure 5, a first tongue conductor 121 and a second tongue conductor 122 made of a conductive material are provided at the tip of the tongue depressor base 110 (which is elongated and slightly wider at the tip) made of an insulating material such as wood or synthetic resin. The first tongue conductor 121 and the second tongue conductor 122 may be composed of metal clips and removably attached to the tongue depressor. When the tongue depressor is pressed against the tongue T of the subject S, an electrical connection between the first tongue conductor 121 and the second tongue conductor 122 and the tongue T is maintained. The shape and size of the tongue depressor may be adjusted so that when the subject S holds the tongue depressor in his or her mouth, an electrical connection between the first tongue conductor 121 and the second tongue conductor 122 and the tongue T is maintained.

[0036] The jaw interaction mechanism 21 is composed of a single adhesive pad or adhesive sheet. As shown in FIG. 6 , a pair of substantially rectangular first jaw electrodes 221 are arranged on the surface or inside of the belt, spaced apart in the longitudinal direction of the adhesive pad. As shown in FIG. 6 , a pair of substantially rectangular second jaw electrodes 222 are arranged on the surface or inside of the adhesive pad, spaced apart in the longitudinal direction of the adhesive pad. Each of the pair of first jaw electrodes 221 and each of the pair of second jaw electrodes 222 are spaced apart in the width direction (short direction) of the adhesive pad. The number, shape, size, and arrangement of the first jaw electrodes 221 and / or second jaw electrodes 222 may be varied in various ways. The jaw interaction mechanism 21 may be composed of multiple adhesive pads or adhesive sheets, with one or more jaw electrodes provided on each adhesive pad. By attaching the adhesive pad to the jaw C of the subject S, a state in which EMS signals can be transmitted to the jaw C of the subject S is maintained through a pair of first jaw electrodes 221 and a pair of second jaw electrodes 222.

[0037] As in the first embodiment, the jaw interaction mechanism 21 may be configured by a jaw supporter (see FIG. 3 ). In this case, the first jaw electrode 221 and the second jaw electrode 222 may be disposed on the inner surface of the jaw supporter or may be built into the jaw supporter.

[0038] As shown in FIG. 4 , the EMS signal generator 40 includes a power supply unit 41, a control unit 42, a first pulse generator 431, a second pulse generator 432, a first output unit 441, and a second output unit 442. The first pulse generator 431 is configured to generate a first EMS signal as a pseudo-waveform signal by generating a pulse signal and adjusting its period and / or amplitude in response to a command from the control unit 42. The second pulse generator 432 is configured to generate a second EMS signal as a pseudo-waveform signal by generating a pulse signal and adjusting its period and / or amplitude in response to a command from the control unit 42. The first EMS signal and the second EMS signal have different frequencies. For example, the first EMS signal may be a low-frequency electrical signal (20 to 100 Hz), and the second EMS signal may be a medium-frequency electrical signal (1000 to 10,000 Hz) or a high-frequency electrical signal (10,000 to 20,000 Hz). The first output section 441 is connected to the first tongue conductor 121 via a terminal 4411 and a conductor L11, and is connected to each of the pair of first jaw conductors 221 via a terminal 4412 and a conductor L21. The second output section 442 is connected to the second tongue conductor 122 via a terminal 4421 and a conductor L12, and is connected to each of the pair of second jaw conductors 222 via a terminal 4422 and a conductor L22.

[0039] (Effects) In the respiratory function recovery device configured as described above, the tongue interaction mechanism 11 maintains an electrical connection between the tongue T of the subject S (animal such as a human) and the tongue conductor 12, and the jaw interaction mechanism 21 maintains a direct or indirect electrical connection between the jaw C of the subject S and the pair of first jaw conductors 221 and the pair of second jaw conductors 222. This causes mutual interference between a first EMS signal generated by the EMS signal generator 40 and passed between the first tongue conductor 121 and the first jaw conductor 221, and a second EMS signal having a different frequency from the first EMS signal and passed between the second tongue conductor 122 and the second jaw conductor 222, thereby stimulating the muscles of the jaw C and tongue T with the interference wave. In particular, a pulse current can be passed through muscle parts of the jaw C that are deep within the jaw C. The influence of the interference waves causes various muscles between the tongue T and the jaw C involved in breathing to contract, thereby restoring or maintaining the strength of the muscles or respiratory function.

[0040] 7, the tongue interaction mechanism 11 may be configured as a finger stall. One or more tongue electrodes 12 are provided on the outer surface, inner surface, or internal surface of the tip (the part corresponding to the distal phalanx of the finger) of the finger stall. The finger stall is attached to a finger (e.g., the index finger) of the subject S or a third party so that the tongue electrode 12 faces ventrally, and the ventral side of the tip of the finger stall is pressed against the tongue T of the subject S, thereby reliably maintaining the tongue electrode 12 electrically connected to the tongue T.

[0041] As shown in Fig. 8, the tongue interaction mechanism 11 may be configured with one or more suction cups. One or more tongue conductors 12 are provided on the surface or inside of the suction cups. By adhering the suction cups to the tongue T of the subject S, the tongue conductor 12 can be reliably maintained in a state where it is electrically connected to the tongue T.

[0042] As shown in FIG. 9 , the jaw interaction mechanism 21 may be configured as a partially open neck hanging member or clip that is wrapped around the back and front of the neck. The neck hanging member is made of an elastic material such as synthetic resin. The neck hanging member may be configured as a plurality of links connected by one or more joint mechanisms, and the relative position of a pair of links connected by the joint mechanisms may be changed by adjusting the bending angle of the joint mechanisms. A pressing member 212 is provided at each of a pair of ends of the neck hanging member. The pressing member 212 may be made of a soft material such as sponge or silicone rubber, or an elastic material. A chin electrode 22 is provided on the surface or inside of each of the pair of pressing members 212 on the chin C side. As shown by the arrows in FIG. 9 , the pair of left and right pressing members 212 may be configured to slide along the neck hanging member. Because the neck hanging member is made of an elastic material, the pressing member 212 can be reliably abutted against the chin C of the subject S. The pressing member 212 may be omitted, and one or more chin electrodes 22 may be provided on the surface or inside of the neck hanging member.

[0043] As shown in Fig. 10, the jaw interaction mechanism 21 may be composed of one or more suction cups. One or more jaw electrodes 22 are provided on the surface or inside of the suction cup. The multiple suction cups may be independent of each other, or may be connected by a connecting member. The connecting member may be formed by the neck hanging member in the embodiment of Fig. 9, and one or more suction cups may be provided on each of both ends of the neck hanging member as the jaw interaction mechanism 21. By adhering the suction cups to the jaw C of the subject S, the jaw electrodes 22 can be reliably maintained in an electrically connected state to the jaw C.

[0044] As shown in FIG. 11 , the jaw interaction mechanism 21 may include a base 210 and a pair of extension portions 211 that extend from the tip of the base 210, bifurcating to sandwich the jaw C of the subject S from the left and right. At least one pair of extension portions 211 of the jaw interaction mechanism 21 is configured to have elasticity using a material such as synthetic resin or metal. Each of the pair of extension portions 211 is provided with a pressing member 212. The pressing member 212 may be configured with a soft or elastic material such as sponge or silicone rubber. A jaw electrode 22 is provided on the surface or inside of each of the pair of pressing members 212 on the jaw C side. The base 210 is provided with a switch 214 for switching the operation of the EMS signal generator 40 ON / OFF. The EMS signal generator 40 may be built into the base 210.

[0045] As shown in FIG. 12 , the jaw interaction mechanism 21 may include a base 210 and a pair of extensions 211 that extend from the tip of the base 210, bifurcating to sandwich the jaw C of the subject S from the left and right. At least one pair of extensions 211 of the jaw interaction mechanism 21 is configured to have elasticity using a material such as synthetic resin or metal. Each of the pair of extensions 211 is provided with a pressing member 212. The pressing member 212 is configured with a rotation shaft 2121 and a substantially cylindrical or columnar roller 2122 that rotates around the rotation shaft 2121. The roller 2122 may be formed in a substantially spherical or regular polyhedral shape. The roller 2122 may be configured from a hard material such as synthetic resin, ceramics, and / or metal. A substantially cylindrical jaw electrode 22 is provided along the outer periphery of the roller 2122. A plurality of jaw electrodes 22 may be arranged spaced apart from one another along the outer periphery of the roller 2122 .

[0046] As shown in Figures 13 and 14, as a modified example of the tongue depressor (e.g., made of stainless steel) constituting the tongue interaction mechanism 11, an adsorption recess 1100 that acts as a suction cup and is locally recessed from the side surface of the base 110 may be provided. When the tongue depressor is applied to the tongue T of the subject S from the surface of the adsorption recess 1100, it is adsorbed and fixed to the tongue T. Therefore, the tongue depressor can be released from the hand. The tongue depressor can be removed from the tongue T. A plurality of adsorption recesses 1100 may be provided on the base 110 of the tongue depressor.

[0047] 15 and 16, jaw interaction mechanism 21 may be configured with an adhesive pad configured to be detachable from jaw C of subject S, and first jaw electrode 221 and second jaw electrode 222 (or jaw electrode 22) may be embedded in the adhesive pad. First jaw electrode 221 and second jaw electrode 222 may be at least partially configured from a conductive gel.

[0048] The respiratory function recovery device according to the present invention contributes to the industry by using EMS signals to recover the function of various muscles involved in the respiratory function of a subject, and can be expanded to include not only humans but also animals such as dogs and cats.
