Pressure-controlled hyperbaric oxygen therapy system using ear caps to reduce ear pain
[0001] The present invention relates to a pressure-controlled hyperbaric oxygen therapy system using an ear cap to reduce ear pain, which can eliminate ear pain that may be caused during hyperbaric oxygen therapy.
[0002] In general, hyperbaric oxygen chamber devices are used to treat users by using high-concentration oxygen in a chamber where a pressure environment higher than atmospheric pressure is created.
[0003] In other words, hyperbaric oxygen therapy is a treatment that creates a high-pressure environment so that the patient can inhale high-concentration oxygen and obtain dissolved oxygen.
[0004] Through this, the oxygen concentration in the patient's body can be increased, and hypoxia can be improved. Hyperbaric oxygen therapy is a treatment method in which a very high concentration of oxygen, for example, almost 100% pure, is breathed for a certain period of time in a state where the pressure is increased higher than the normal breathing environment, and it is used to effectively supply oxygen to tissue cells damaged by decompression sickness, trauma, inflammation, edema, and bacterial infection, thereby improving the treatment effect and quality.
[0005] Recently, hyperbaric oxygen chambers have been used for non-medical treatment or health purposes at relatively low pressures, such as hyperbaric acclimation training, in addition to traditional medical hyperbaric oxygen therapy.
[0006] In particular, multi-person hyperbaric oxygen chambers are equipped with masks for each person to breathe high-concentration oxygen.
[0007] When using these hyperbaric oxygen chambers, various problems may occur, such as the human pressure regulation function not being able to keep up with the changes in air pressure inside the chamber, or the eardrum being damaged by the pressure difference.
[0008] Accordingly, a technology is required that can eliminate ear pain that may be caused during hyperbaric oxygen therapy.
[0009] The technical problem to be achieved by the present invention is to provide a pressure-controlled hyperbaric oxygen treatment system using an ear cap to reduce ear pain, which can prevent ear pain by first blocking the pressure of atmospheric gas pressure transmitted to the ear through the ear cap, and then slowly transmit the pressure to the ear through a connecting tube to prevent ear pain and balance the pressure.
[0010] In order to achieve the above-described object, an embodiment of the present invention provides a pressure-controlled hyperbaric oxygen treatment system using ear caps for reducing ear pain, comprising: a mask comprising a mask body that fits tightly against the mouth and nose of a user entering a hyperbaric oxygen chamber; an oxygen tube connector coupled to one side of the face of the mask body for supplying respiratory gas; and a carbon dioxide tube connector coupled to the other side for discharging respiratory gas; an ear cap that fits tightly around the user's ear to block the pressure of atmospheric gas within the hyperbaric oxygen chamber; a connecting tube that is connected to the ear cap and provides a predetermined pressure to the ear; and a pulse-driven pressure control unit that controls the pressure of atmospheric gas within the hyperbaric oxygen chamber or the pressure of atmospheric gas and respiratory gas so that a pulse waveform appears during at least one of a pressure-raising and pressure-reducing process from a starting pressure to a final pressure, thereby blocking or reducing the pressure.
[0011]
[0012] Here, one end of the connecting tube is connected to an oxygen supply unit of a high-pressure oxygen chamber that supplies atmospheric gas and respiratory gas, and the other end is connected to the ear cap, so that oxygen can be supplied from the oxygen supply unit to the ear cap.
[0013]
[0014] In addition, one end of the connecting tube may be connected to the mask body and the other end may be connected to the ear cap, so that the pressure inside the mask and the pressure inside the ear cap may be the same.
[0015]
[0016] Additionally, the pulse waveform may form a section in which the amplitude increases as it moves away from the starting pressure point and decreases as it approaches the reaching pressure point.
[0017]
[0018] In addition, in the case of the boosting process, the pulse waveform may have a pulse falling width smaller than the pulse rising widths immediately before and immediately after, and in the case of the depressurizing process, the pulse falling width may have a pulse rising width larger than the pulse rising widths immediately before and immediately after, and the pulse falling width and the pulse rising width may be the height difference between the peak and the trough, respectively.
[0019]
[0020] Additionally, in the case of the above-mentioned pressure-boosting process, the pulse-falling width may be 50% or less of the immediately preceding pulse-rising width, and in the case of the above-mentioned pressure-reducing process, the pulse-falling width may be 200% or more of the immediately preceding pulse-rising width.
[0021]
[0022] Additionally, the pulse waveform may include a section in which the half-period of the pulse with the large amplitude is greater than the half-period of the pulse with the small amplitude.
[0023]
[0024] Additionally, the pulse waveform may form a section in which the amplitude / semi-period value increases as it moves away from the starting pressure point, and the amplitude / semi-period value decreases as it approaches the reaching pressure point.
[0025]
[0026] In addition, at least one of the section from the starting pressure to the start of the pulse waveform and the section from the end of the pulse waveform to the arrival pressure may include a linear or curved section.
[0027]
[0028] In addition, the pulse-driven pressure control unit may include an oxygen supply unit that supplies oxygen to at least one of the high-pressure oxygen chamber and the mask, an exhaust unit that exhausts respiratory gas to reduce pressure in at least one of the high-pressure oxygen chamber and the mask, and a control unit that controls the oxygen supply unit and the exhaust unit by inducing the pulse waveform.
[0029]
[0030] In addition, the pulse-driven pressure control unit may further include a feedback unit that mixes at least a portion of the respiratory gas discharged by the discharge unit with the oxygen supplied by the oxygen supply unit and supplies them together when supplying the respiratory gas.
[0031] According to the present invention, ear pain is prevented by primarily blocking the pressure of atmospheric gas transmitted to the ear through the ear cap, and ear pain is prevented by slowly transmitting the pressure to the ear through the connecting tube to balance the pressure, and middle air pressure disorder is prevented through the pulse-driven pressure control method, and the pressure adaptability of the ear can be increased in the pressurized and depressurized sections, and the equalization time and treatment time can be shortened by omitting the communication process using hand signals with the user.

[0039] Hereinafter, an embodiment of the present invention having the above-described features will be described in more detail with reference to the attached drawings.
[0040]
[0041] A pressure-controlled hyperbaric oxygen treatment system using an ear cap for reducing ear pain according to an embodiment of the present invention comprises a mask (110) that is fitted to the mouth and nose of a user who has entered a hyperbaric oxygen chamber (10), an oxygen tube connector (112) that is connected to one side of the face of the mask body (111) to supply respiratory gas, and a carbon dioxide tube connector (113) that is connected to the other side to discharge respiratory gas, an ear cap (120) that is fitted to the user's ear to block the atmospheric gas pressure in the hyperbaric oxygen chamber (10), a connection tube (130) that is connected to the ear cap (120) to provide a predetermined pressure to the ear, and a pulse-driven pressure control regulator (150) that controls the atmospheric gas pressure in the hyperbaric oxygen chamber (10) or the atmospheric gas and respiratory gas pressure so that a pulse waveform appears in at least one of the pressure-raising and pressure-reducing processes from the starting pressure to the final pressure, thereby blocking or reducing the pressure that may be induced during hyperbaric oxygen treatment. The main purpose is to eliminate ear pain.
[0042]
[0043] Hereinafter, with reference to the drawings, a pressure-controlled hyperbaric oxygen therapy system using an ear cap for reducing ear pain of the aforementioned configuration is specifically described as follows.
[0044]
[0045] First, the mask (110) is composed of a mask body (111) that fits tightly against the mouth and nose of a user who has entered a hyperbaric oxygen chamber (10) for hyperbaric oxygen therapy to prevent loss of respiratory gas, an oxygen tube connector (112) that is connected to one side of the face of the mask body (111) to supply respiratory gas from an oxygen supply unit of the hyperbaric oxygen chamber (10), and a carbon dioxide tube connector (113) that is connected to the other side to discharge respiratory gas of carbon dioxide that is exhausted after the user breathes.
[0046] Here, a silicone pad is formed on the edge of the mask body (111) that comes into contact with the face, thereby providing a soft wearing feeling, minimizing discomfort, and increasing airtightness.
[0047]
[0048] Next, the ear cap (120) wraps around the user's ear to seal it tightly and block the atmospheric gas pressure inside the high-pressure oxygen chamber (10), thereby preventing excessive pressure from being applied to the ear.
[0049]
[0050] Next, the connecting tube (130) is connected to the ear cap (120) to provide a predetermined pressure to the user's ear, that is, to provide pressure so that the user does not feel pain in response to pressure changes due to pressure increase and decrease within the hyperbaric oxygen chamber (10).
[0051] For example, as illustrated in (a) of FIGS. 1 and 2, one end of the connecting tube (130) is connected to the oxygen supply unit of the high-pressure oxygen chamber (10) that supplies atmospheric gas and respiratory gas, and the other end is connected to the ear cap (120), so that oxygen can be directly supplied from the oxygen supply unit to the ear cap (120), thereby controlling the pressure directly transmitted to the user's ear by the oxygen supply unit.
[0052]
[0053] Alternatively, as illustrated in (b) of FIGS. 1 and 2, one end of the connecting tube (130) is connected to the mask body (111) and the other end is connected to the ear cap (120), so that the pressure inside the mask (110) and the pressure inside the ear cap (120) are the same, thereby controlling the pressure indirectly transmitted to the user's ear by the oxygen supply unit.
[0054]
[0055] Next, the pulse-driven pressure control control unit (150) controls the atmospheric gas pressure or the atmospheric gas and respiratory gas pressure within the high-pressure oxygen chamber (10) so that a pulse waveform appears during at least one of the pressure-raising and pressure-reducing processes from the starting pressure to the final pressure, thereby blocking the pressure transmitted to the user's ears (see (a) of FIG. 3) or reducing the pressure transmitted to the user (see (b) of FIG. 3).
[0056]
[0057] Meanwhile, a sensor (140) may be additionally provided, and the sensor (140) detects the external ear transmission pressure and the middle ear transmission pressure inside the ear cap (120), respectively, and transmits the measured pressure values to the pulse-driven pressure control unit (150), and, according to the pressure value measured by the sensor (140), the atmospheric gas pressure or the pressure of the atmospheric gas and the respiratory gas in the hyperbaric oxygen chamber (10) is controlled so that a pulse waveform appears in at least one of the pressure-raising and pressure-reducing processes from the starting pressure to the final pressure, thereby blocking the pressure transmitted to the user's ear (see (a) of FIG. 3) or reducing the pressure transmitted to the user (see (b) of FIG. 3).
[0058]
[0059] Through this configuration, ear pain is prevented by primarily blocking the pressure of atmospheric gas transmitted to the ear through the ear cap (120), and ear pain is prevented by slowly transmitting the pressure to the ear through the connecting tube (130) to balance the pressure, and whether pain occurs is diagnosed through the pressure value by the sensor (140), and barotrauma is prevented through the pulse-driven pressure control method, and the pressure adaptability of the ear can be increased in the pressurized and decompressed sections, and the equalizing time and treatment time can be shortened by omitting the communication process through hand signals with the user.
[0060]
[0061] Meanwhile, the pressure increase and decrease process by the pulse-driven pressure control regulator (150) is described in detail as follows.
[0062] As mentioned above, the pulse-driven pressure control regulator (150) controls the atmospheric gas pressure or the atmospheric gas and respiratory gas pressure so that a pulse waveform appears during at least one of the pressure-raising and pressure-reducing processes from the starting pressure to the final pressure.
[0063] Meanwhile, problems such as high-pressure gas pressure disturbance occur due to rapid pressure changes caused by pressure increase and / or pressure decrease of the atmospheric gas within the high-pressure oxygen chamber (10). Through the pressure control method according to the present embodiment, the atmospheric gas pressure within the high-pressure oxygen chamber (10) can be increased and / or decreased in a pulse wave form.
[0064] For example, when a user wears a mask (110) inside a hyperbaric oxygen chamber (10), not only the atmospheric gas pressure inside the hyperbaric oxygen chamber (10) but also the pressure of the respiratory gas provided by the mask (110) can be increased and / or decreased to assist in the increase and / or decrease of the atmospheric gas inside the hyperbaric oxygen chamber (10) so as to prevent problems such as, for example, barotrauma.
[0065] According to an embodiment, the pressure of the respiratory gas provided by the mask (110) may be changed in a gentle manner, without including a pulse waveform, unlike the pressure of the atmospheric gas within the hyperbaric oxygen chamber (10).
[0066] For reference, the high-pressure oxygen gas may be provided as an atmosphere gas in the high-pressure oxygen chamber (10) from the oxygen supply unit, or may be provided as both an atmosphere gas and a breathing gas. The atmosphere gas refers to an atmosphere gas inside the high-pressure oxygen chamber (10), and the breathing gas refers to a gas provided through the user's mask (110). If the user in the high-pressure oxygen chamber (10) does not have a mask (110), the atmosphere gas becomes the user's breathing gas, and if the user in the high-pressure oxygen chamber (10) wears a mask (110), the user breathes the breathing gas.
[0067] Here, the high-pressure gas provided as the atmospheric gas may be a high-pressure gas of the general atmosphere.
[0068]
[0069] In addition, the pressure of the high-pressure gas may preferably be applied to the medical high-pressure oxygen chamber (10) at 2 atm or more, but is not particularly limited thereto.
[0070] In addition, in the case of a multi-person hyperbaric oxygen chamber, it can be used by providing individual masks (110), and the pressure of multiple masks (110) can be individually controlled in a pulse wave form or controlled collectively in a pulse-driven pressure control unit (150).
[0071] In addition, the pressure pulse waveform formed by the pulse-driven pressure control regulator (150) can be recognized externally through a display panel (not shown).
[0072] In addition, by controlling the pulse waveform to appear during the pressure-raising and / or depressurizing process by the pulse-driven pressure control regulator (150), the user can solve problems such as barotrauma caused by rapid changes during the pressure-raising and / or depressurizing process, and for example, by including a pulse waveform to perform pressure-raising and / or depressurizing, the user can reduce problems such as barotrauma by quickly performing small stepwise increases / decreases and then repeating small opposite decrease / ascent changes as buffers.
[0073] In addition, by controlling the stepwise rise / fall change range of the pulse waveform and the successive opposite fall / rise change range, and at the same time controlling the time of the pulse waveform, it is possible to have a pressure-raising / depressurizing transition time suitable for each user rather than a gradual pressure-raising / depressurizing process of a slope, or to shorten the transition time.
[0074] That is, by repeating stepwise rise / fall changes in short cycles followed by buffered opposite-direction fall / ascent changes, rather than applying continuous pressure stress such as gradual increase / decrease in a slope, it is possible to expect personalized solutions to problems such as mesobaric dysrhythmias in a shorter period of time.
[0075] Referring to FIG. 4, the pulse waveform can form a section in which the amplitude increases as it moves away from the starting pressure point and decreases as it approaches the final pressure point, and both the transition section 1, which is the pressure-boosting process, and the transition section 2, which is the pressure-reducing process, are shown. However, unlike FIG. 4, depending on the embodiment, the pulse waveform can be made to appear only in either the pressure-boosting or pressure-reducing process.
[0076] That is, the starting pressure in the pressurization process or the final pressure in the depressurization process can be atmospheric pressure, and the final pressure in the pressurization process and the starting pressure in the depressurization process can be, for example, within a range of about 2 to 5 atmospheres, and as in FIG. 4, the starting pressure 1 in the transitional section 1 of the pressurization process can be set to be the same as the final pressure 2 in the transitional section 2 of the depressurization process, and also the final pressure 1 in the transitional section 1 and the starting pressure 2 in the transitional section 2 can be set to be the same.
[0077] Additionally, the pulse waveform includes a section where the amplitude increases as it moves away from the starting pressure point and decreases as it approaches the target pressure point, and a stepwise rise / fall change followed by a buffered opposite fall / rise change in short cycles, initially with a small change in amplitude but then a larger change as the user becomes accustomed to the pressure change, and later a smaller change again as it approaches the target pressure, which can greatly reduce problems such as mesobaric pressure disturbances for the user.
[0078]
[0079] Referring to Fig. 5, in the case of a pressure-up process, the pulse waveform has a pulse-fall width that is smaller than the pulse-rising widths immediately before and immediately after, and in the case of a pressure-down process, the pulse-fall width that is larger than the pulse-rising widths immediately before and immediately after, wherein each of the pulse-fall width and the pulse-rising width is the height difference between the peak and the trough.
[0080] Although Fig. 5 does not show the pulse waveform of the depressurization process, it can be understood that the waveform progresses in the opposite direction to the waveform progress of the illustrated boosting process, and in Fig. 5, the pulse falling width H2 in the boosting process is smaller than the pulse rising width H1 immediately before and the pulse rising width H3 immediately after.
[0081] In addition, if we consider the waveform progression of Fig. 5 in reverse, that is, if we consider the pulse to progress so as to be decompressed from the H4 direction to the H1 direction, we can see that the pulse falling width H3 during the decompressing process is larger than the pulse rising width H4 immediately before and the pulse rising width H2 immediately after.
[0082] In addition, it can be seen that during the decompression process, the pulse rising width H2 is smaller than the pulse falling width H3 immediately before and the pulse falling width H1 immediately after, and unlike Fig. 4, when the pulse waveform appears only in one of the pressure increasing and decompression processes, a difference may occur between the pulse falling width and pulse rising width of successive pulses in the pulse waveform.
[0083] For example, as illustrated in Fig. 5, in the case of a boosting process, the pulse falling width H2 may be 50% or less of the previous pulse rising width H1, and if we consider the waveform progression of Fig. 5 in reverse, in the case of a depressurizing process, the pulse falling width H3 may be 200% or more of the previous pulse rising width H4.
[0084] In addition, in the case of a decompression process, the pulse rise width H2 may be less than 50% of the previous pulse fall width H3.
[0085]
[0086] According to this embodiment, in the case of a boost pulse waveform, the pulse falling width is smaller than the immediately preceding and immediately succeeding pulse rising widths, and in the case of a depressurizing pulse waveform, the pulse falling width is larger than the immediately preceding and immediately succeeding pulse rising widths, thereby reducing the continuous buffered opposite falling / rising changes rather than the short periodic stepwise rising / falling changes, thereby reducing the boost / depressurizing transition time while also significantly reducing problems for the user, such as, for example, mesobaric dysrhythmias.
[0087] In addition, the pulse waveform may include a section in which the half-period (T / 2) of a pulse with a large amplitude is greater than the half-period (T / 2) of a pulse with a small amplitude, and in FIG. 5, “T1 / 2” is the half-period (T / 2) of a pulse with a small amplitude, and “T2 / 2” is the half-period (T / 2) of a pulse with a large amplitude, where “T1” is the period (T) of a pulse with a small amplitude, and “T2” is the period (T) of a pulse with a large amplitude.
[0088] For example, as the amplitude increases, the half-period (T / 2) of the pulse can be controlled to gradually increase, and as the amplitude decreases, the half-period (T / 2) of the pulse can be controlled to gradually decrease.
[0089] According to this embodiment, by making the half-period (T / 2) larger for pulses with large amplitudes, problems such as, for example, barotropic disturbances caused by pulses with large amplitudes can be reduced.
[0090] Referring to FIGS. 4 to 6, the pulse waveform can form a section in which the amplitude (h) / half-cycle (T / 2) value increases as it moves away from the starting pressure point and the amplitude / half-cycle value decreases as it approaches the reaching pressure point.
[0091] For example, as illustrated in FIG. 4, the half-cycle (T / 2) value of each pulse can be controlled to be kept constant or substantially constant, the amplitude gradually increased, and then gradually decreased as it approaches the target pressure.
[0092] Alternatively, as illustrated in Fig. 5, the period (T / 2) value of each pulse may also be changed along with the change in amplitude.
[0093] For example, the value of the half-period (T / 2) of each pulse can be changed in the same direction (increase / decrease) as the direction of change of the amplitude (increase / decrease) but with the amount of change being smaller than the amplitude, or can be changed in the opposite direction (decrease / increase) to the direction of change of the amplitude (increase / decrease).
[0094] Alternatively, as illustrated in FIG. 6, the amplitude of each pulse may be set to be substantially the same or nearly the same and the half-cycle (T / 2) value may be adjusted.
[0095] In Fig. 6, since the pulse waveform has a shorter period when moving away from the starting pressure point (Ta > Tb), the amplitude (h) / half period (Tb / 2) value of the section farther from the starting pressure point increases compared to the amplitude (h) / half period (Ta / 2) value of the section close to the starting pressure point, and conversely, since the period becomes longer when moving closer to the reaching pressure point (Tc < Td), the amplitude (h) / half period (Td / 2) value of the section close to the reaching pressure point increases compared to the amplitude (h) / half period (Tc / 2) value of the section far from the reaching pressure point, so that the pulse waveform change can be gradual in the vicinity of the starting pressure and the reaching pressure, respectively.
[0096] For example, referring to FIG. 6, at least one of the section from the starting pressure to the start of the pulse waveform and the section from the end of the pulse waveform to the arrival pressure may include a linear or curved section.
[0097] Referring to part "A" of Fig. 6, it can be seen that a curved section is formed at the point where the pulse waveform and the reached pressure are connected. The curved section illustrated in Fig. 6 can also be applied to other waveform graphs such as Figs. 4 and 5, and the same applies to linear sections, although not illustrated.
[0098]
[0099] Meanwhile, the pulse-driven pressure control control unit (150) may include an oxygen supply unit that supplies oxygen to at least one of the high-pressure oxygen chamber (10) and the mask (110), an exhaust unit (not shown) that exhausts respiratory gas to reduce pressure in at least one of the high-pressure oxygen chamber (10) and the mask (110), and a control unit (not shown) that controls the oxygen supply unit and the exhaust unit by inducing a pulse waveform.
[0100] For example, the oxygen supply unit supplies gas to at least one of the high-pressure oxygen chamber (10) and the mask (110), and a pulse wave pressure is formed by the control of the control unit according to the gas supply by the oxygen supply unit. When the mask (110) is provided, not only the atmospheric gas in the high-pressure oxygen chamber (10) but also the breathing gas in the mask (110) is supplied by the oxygen supply unit according to an embodiment, so that a pulse wave pressure can be formed by the control of the control unit.
[0101] In addition, the discharge unit discharges gas to reduce pressure in at least one of the high-pressure oxygen chamber (10) and the mask (110), and, like the oxygen supply unit, discharges gas from the high-pressure oxygen chamber (10) or from both the high-pressure oxygen chamber (10) and each mask (110), wherein, under the control of the control unit, gas is discharged from at least one of the high-pressure oxygen chamber (10) and the mask (110), and a pulse wave pressure is formed by the gas supply by the oxygen supply unit.
[0102] Here, the control unit controls the gas supply by the oxygen supply unit and the gas discharge by the discharge unit to induce a pulse waveform. Fig. 7 illustrates that the on / off of the oxygen supply unit and the on / off of the discharge unit are controlled according to the control of the control unit, and the gas pressure forms a pulse waveform.
[0103] That is, as shown in Fig. 7, the pressure increase by the oxygen supply unit and the pressure decrease by the discharge unit are mixed according to the control of the control unit, and a pulse waveform of the pressure increase process can be formed. For example, the gas supply by the oxygen supply unit and / or the gas discharge by the discharge unit can be controlled through the duty ratio control by the control of the control unit and / or the gas supply amount / gas discharge amount control. That is, the amplitude or / and the half-cycle (T / 2) per unit pulse can be adjusted through the duty ratio control or / and the gas supply amount / gas discharge amount control.
[0104] In addition, the gas supply passage by the oxygen supply unit and the gas discharge passage by the discharge unit may be formed separately from each other or may use the same passage depending on the embodiment. When the same passage is used as the gas supply passage and the gas discharge passage, the oxygen supply unit and the discharge unit may be provided together at the end of the same passage, or the oxygen supply unit and the discharge unit, or the discharge unit and the oxygen supply unit may be provided at the end of a passage section extended from the same passage section and the end of the same passage section.
[0105] Meanwhile, although not shown, the pulse-driven pressure control regulator (150) may further include a feedback unit (160), and the feedback unit (160) mixes at least a portion of the gas discharged by the discharge unit with the gas supplied by the oxygen supply unit so that the gas is supplied together when the gas is supplied, or feeds the mixture back to the gas passage supplied by the oxygen supply unit so that the mixture is resupplied.
[0106] At this time, the control unit can induce a pulse waveform by controlling the oxygen supply unit, exhaust unit, and feedback unit (160).
[0107] For example, the feedback unit (160) may, in the case of pressure increase, mix some or all of the gas discharged by the discharge unit with the gas supplied by the oxygen supply unit or feed it back to the gas passage, and in the case of pressure decrease, block some or all of the gas discharged by the discharge unit from mixing with the gas supplied by the oxygen supply unit or feeding it back to the gas passage.
