[Embodiment] Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. Here, various modifications and changes can be made to the present invention, and the specific examples thereof are shown in the drawings and described in detail below. However, the present invention is not limited to the above, and various configurations can be made within the scope defined by the scope of the patent application. Fig. 1A is a piping diagram illustrating the principle of oxygen generation; the figure shows positive pressure and pressure swing adsorption (PSA) caused by positive pressure over time and positive and negative pressure swing adsorption method (VPSA) caused by positive pressure and negative pressure. The graph of the pressure change; the iB diagram is a graph showing the positive pressure and pressure swing adsorption (PSA) caused by positive pressure and the nitrogen adsorption amount and pressure of positive and negative pressure swing adsorption (VPSA) caused by positive pressure and negative pressure. Figure 1 is a brief description of the positive pressure caused by the pressure of the positive pressure feedstock. The pressure swing adsorption method (PSA) and the positive and negative pressure swing adsorption method (VPSA) caused by the positive pressure and negative pressure feed air. In the first drawing of Fig. 1, the raw air which is introduced into the external air and compressed by the compressor C is introduced into the first adsorption cylinder 10a via a one-way three-way switching valve 109a. The first adsorption tube i〇8a contains a catalytic smectite, and nitrogen is separated by the zeolite to generate oxygen. The oxygen thus separated is flowed into the product drum through a check valve not shown. When the internal pressure of the first adsorption cylinder 108a rises, the three-way 200924809 switching valve 109a is switched to exhaust gas for exhaust. At this time, the pressure equalizing valve 107 is opened, and is moved to a pressure equalizing operation of the second adsorption tube 10 8b by using a portion of the oxygen concentrated by the first adsorption tube i 8a. Secondly, in order to carry out the desorption operation of the first adsorption cylinder 10 8 a (discharging nitrogen and moisture) and introducing the compressed air into the second adsorption cylinder 1 to open the two-way switching valve l〇9a, the second adsorption cylinder is entered. I〇8b - The oxygen produced by the compressed empty fluorine separation flows into the product drum through a check valve not shown in the figure. Subsequently, when the pressure sensor not shown in the figure detects the arrival of the set pressure, the pressure equalizing valve 1 〇 7 is turned on for a certain period of time, and then the second adsorption tube 108b is washed and equalized. Further, when the pressure equalizing valve 107 is opened, the oxygen generated by the separation in the second adsorption column 108b is sent to the outlet portion of the first adsorption tube 108a, and the sealed zeolite is washed. When the above operations are repeated for a certain period of time, oxygen can be continuously and stably supplied. If the above two adsorption valves are switched between two three-way switching valves for Φ oxygen, in order to achieve the pressure change indicated by the solid line in Fig. 1B, the positive pressure compressed air is sent to the adsorption cylinder to adsorb nitrogen. And in about! The method of performing desorption operation under atmospheric pressure is called positive pressure pressure swing adsorption method (CPSA); the desorption operation shown in the dotted line of Fig. 1B is decompressed to vacuum, and the method of washing the built-in Buddha stone is more actively carried out. It is called positive and negative pressure swing pressure adsorption (VPSA). As shown in the ic diagram of Figure 1, when the nitrogen adsorption capacity of the positive pressure swing pressure adsorption method (psA) is compared with the positive and negative pressure swing pressure adsorption method (vpsA) in 200924809, even under the same pressure difference, the nitrogen adsorption amount is also higher. Less, so it is better to use positive and negative pressure swing adsorption method (VPSA). However, at this time, it is necessary to be able to supply both the positive pressure compressed air and the decompressed negative pressure air. Such compressors are usually large and therefore difficult to use in combination with a small oxygen concentrating device for carrying. In contrast, the positive pressure swing pressure adsorption method (PSA) can be used in combination with a small-sized oxygen concentrator for carrying, as long as it can only deliver a compressor that supplies positive compressed air. Hereinafter, an example of a portable small oxygen concentrating device constructed by the above-described positive pressure-change C adsorption method will be described in detail.礼。 Concentrate--<- 芷菔 成 / / Figure 2 A Figure 1 shows an embodiment of the invention of the small = concentrating device 1 together with the nasal cannula seen from the front left obliquely above you: view ' Fig. 1B is a perspective view showing the appearance of the carrying cassette 4 for the small oxygen concentrating device 1.

In the figure, the components of the previously described constituent elements are assigned and the description is omitted. The double line is the line 24 of the air, oxygen, and nitrogen passages and is represented by the line 24a to the line 24g. Further, the thin solid line indicates the wiring of the power supply or the electrical signal. The following uses the integrated compressed air generating unit to filter Device

The case of the combination 22 and the compressor 10 is explained. Further, the outside air is introduced into the inside through the intake port 2a, and the outer main casing 2 is discharged through the exhaust port to be shown in a broken line in the closed container. In Figure 4, the order of the air flow is introduced in order. The raw material air (outside air) enters the filter assembly 22 via the above-described line 24 in the direction of the arrow F. The raw material air filtered by the transition unit assembly 22 enters a compressor 10 which is located in the soundproof chamber 3 (indicated by a broken line). The compressor which is integrally formed with the filter assembly 22 is as described above. fixed. Next, the filtered raw material air is pressurized into compressed air by the rectifying mechanism of the compressor 1Q described later. At this time, since the pipe 24c is sent to the pipe 24c in a temperature rising state, the pipe 24c and the heat dissipating effect are excellent. 2 5 Connect 'and cool with the air supply of fan 30. As a result of the compression of the compressed two gas, the adsorbent zeolite having a reduced function at two temperatures can fully achieve the function of adsorbing nitrogen and generating oxygen, 22 200924809 and concentrating the oxygen to about 90% or more. The compressed air is alternately supplied via the line 24c to the first adsorption cylinder 108a and the second adsorption cylinder 108b which are arranged in parallel as described above. Here, the three-way switching valves 109a, 1 〇 9b connecting the switching valves are as shown in the drawing. Further, in order to perform the cleaning operation of removing the exhaust gas of the first adsorption column 10a and the second adsorption tube 10b, the line 24f is connected to the three-way switching valves 109a, 10b as shown in the drawing. Further, a muffler 31 is connected to the downstream side of the line 24f for exhausting the exhaust gas and discharged to the outside by the exhaust port 2b. In the first adsorption tube 10a and the second adsorption tube 1〇8b, the catalyst adsorbent zeolite is separately stored, and the X-type zeolite having a ratio of Si2〇3/Al2〇3 of 2.0 to 3.0 is used, and A12 is used. At least 8 8 % of the tetrahedral (triangular pea) units of 〇3 are bonded to the cations of the bell, so that the amount of nitrogen adsorption per unit weight is increased. In particular, it is preferred to use a zeolite having a particle measurement value of less than 1 mm and at least 88% of a tetrahedral (triangular pyramid) unit bonded to a lithium ruthenium ion. The use of this type of Buddha stone can reduce the amount of raw material air used to produce oxygen. As a result, the compressor i 0 that generates compressed air can be further miniaturized, and further noise reduction can be sought. On the other hand, as shown in the figure, the pressure equalizing valve 107 composed of the check width, the throttle, and the on-off valve is connected to the outlet branch on the upper side of the first adsorption cylinder 108a and the second adsorption cylinder 108b. Further, the downstream side of the pressure equalizing valve 1〇7 is connected to the merged official road 24d, and the product drum ij is stored as shown in Fig. 23 200924809. The container which separates and generates oxygen of about 90% or more is connected to the pipe 24d. Further, each of the adsorption cartridges is provided with a pressure sensor (not shown) for detecting the pressure in the cylinder. A pressure regulator J 12 is disposed on the downstream side of the product drum 111 for self-adjusting a so-called controller that sets the oxygen pressure on the outlet side. The oxygen concentration sensor 114 (zirconia type or ultrasonic type) is connected to the downstream side of the pressure regulator / 12 via a line 24e to intermittently (every 1 to 3 minutes) 0 or continuously to perform oxygen concentration detection. On the downstream side thereof, a proportional opening degree valve 11 (which is opened and closed in conjunction with the above-described oxygen flow rate setting button 8) is connected via a line 24g and the oxygen flow sensor 1 W is connected to the downstream side thereof. To control the breathing synchronization, a demand valve 117 is connected to the downstream side of the oxygen flow sensor 丨16 via the negative pressure circuit substrate, and then connected to the oxygen outlet 7 of the small oxygen concentrating device 1 via the sterilizing network 119. According to the above configuration, the nasal cannula 14 enables the patient to inhale and condense oxygen to about 90% or more at a maximum flow rate of 5 L (liters per minute). ❹ Next 'Power system by (1) AC connector 19: can rectify AC power (commercial AC power) into a switch-regulated type of DC voltage set and relay AC connector connector 130; (2) Built-in battery 228: Storage At the bottom of the main casing 2; (3) the external battery 227 is detachably provided via the AC joint connector 131; and (4) the power supply control circuit 226 and the like. The built-in battery 228 and the external battery 227 are rechargeable battery cells, and the built-in battery 228 is charged by the power supply of the power control circuit 226.

The power control circuit 226 automatically determines the order of the first power supply state, the first supply state, and the second power supply state. ▲ Further, the power control circuit 226 is also reconnected: [D recognizes the code identification circuit 230, and can prevent situations such as 'charged battery power exhaustion. That is, in case of anti-=. The situation that the electric battery is exhausted is to connect a plurality of charging; the type = 228 is better, but when the connection of a plurality of batteries is so, the power conversion is complicated, and the method cannot be individually tested. Consumption of electricity. Therefore, in a plurality of rechargeable batteries 228, ..., 228, in order to be able to control the automatic switching of the fully discharged battery to the fully charged rechargeable battery, the identification code identifying mechanism and the charging state detecting mechanism are separately provided.

The AC connector 19 is not affected by different frequencies and changes in voltage, and can generate a set DC voltage, and it is preferable to be able to form a compact and lightweight switch. However, it is usually a series type. Further, the built-in battery 228 and the external battery 227 have a small storage effect at the time of charging, and a lithium ion or lithium ion battery which can be fully charged when recharged is preferable, but a nickel cadmium battery or a nickel hydride battery may be used. In addition, it is also possible to form an external battery with a battery case of No. 2 (C) battery that is easy to use for the emergency. The central control unit 200 stores a program that can be switched to the most appropriate operation mode in response to the amount of oxygen generated, and passes through the motor control units 2〇1 and 26

200924809 The wind j control unit 203 respectively rotates the two at a low speed when the oxygen is required to be generated to rotate the compressor 1 尚 at a constant speed, respectively: a small amount is required to be generated.

And the removal of the exhaust gas in the second adsorption cylinder 108b, which controls the driving of the oxygen concentration sensor 114 and the proportional opening valve lu, the flow sensor ι6, and the demand valve 117. The compressor 10 having a total weight of about 500 g is controlled by a shift control unit incorporated in the motor control unit 201, and performs a rotation control of a DC motor including an outer rotor type electric motor in a sinusoidal rotation waveform to reduce the operation sound. The compressor 10 can be operated at various speeds to generate the necessary positive pressure level and flow rate, with only a small amount of noise, vibration and heat, small and lightweight, and can be operated with a small amount of power consumption. By setting the shift controller of the shift control mechanism to the motor control 27 200924809, the speed of the compressor 10 can be changed from the patient's activity level and environmental conditions. Therefore, when the patient is in a sitting or lying position and the like, according to the breathing synchronization, the demand valve 117 presumes that the patient's oxygen demand is low, the driving rotational speed of the compressor 10 can be automatically reduced 2, the patient is standing, moving, or as In the state where the GPS is estimated to have a high oxygen concentration and low altitude, it is estimated that the oxygen demand of the patient can be automatically increased when the oxygen demand is increased.

Power has Gong 28 200924809

The three-way switching valves 109a and 101b can use a solenoid valve which is generally called a direct-acting type and performs a switching operation by a magnetic force at the time of energization. Such a solenoid valve has a problem of large power consumption because it is only operated by electric power. Therefore, a pilot (or pilot, pil〇t) type three-way switching valve can also be used as the three-way switching valves 109a, l〇9b. This piloted two-way switching valve can operate with a small amount of power consumption and efficient use of the air pressure of the compressor', which is reduced from the previous 8W to 〇 5W, resulting in a significant reduction in power.

The ridge piece Cangzhou has the opening when t reaches the set pressure, and the elastic force of 200924809 is closed when the set pressure is lower.) Next, the filter assembly 22 will be described with reference to the exploded view of Fig. 7 with reference to Fig. 7. Filter assembly 22 has a bottomed cylindrical casing 50. One end of the casing 50 is compressed into an air introduction port (opening) 50p formed by a beak ring 49 built in the outer circumferential surface groove 38a of the cover 38, and the inside thereof Forming the volume portion η. Also worn on the bottom surface 50d of the chassis 5 The through hole 50b, the outer peripheral surface φ of the casing 50, the ring-shaped ring 49 in the groove 50a can be press-fitted into the main opening 32P in a compressed state, and the air is introduced into the volume portion η of the casing, in the case 50 outer peripheral surface fixed; l-shaped joint 37 (indicated by a broken line in Fig. 6) as an air introduction tube. ^ For the primary filtration of air introduced by the L-shaped joint 37, the machine 50 contains the first cylindrical filter 51 and forming a space around the outer periphery thereof as shown in the drawing. The second cylindrical filter 52 is disposed coaxially with the first cylindrical filter 51 for performing secondary filtering of the primary filtered air and feeding it. The through hole 50b. Both ends of each of the cylindrical filters 51, 52 are in contact with the inner wall and the bottom surface 50d of the cover 38 in a manner as shown in the drawing to maintain a fixed state. Further, the metal is sintered to the filter 53 to cover the through hole 50b. The first and second cylindrical filters may be composed of a phenol resin impregnated fiber and have a filtration performance with a standard filtration accuracy of 40 μm. Here, only the first cylindrical filter 51 may be used. A general filter that folds over the dielectric fibers into a folded shape. Also, 200924809 Fig. 8A is a perspective view showing a cylindrical filter 5b, which is a part of a laminated phenol (resin fiber) sheet 55, and 8B is a stupid phenol. An enlarged view of the (resin fiber) sheet 55 is shown in Fig. 8A, in which at least any of the first cylindrical damper 51 and the second cylindrical damper 52 is impregnated with the benzene resin fiber 55. The spiral shape is laminated into a strip-shaped tubular shape, and heat-cures the benzene tree-lipid.

Fig. 9A of Fig. 9 is an enlarged view of the metal sintered filter 53, and Fig. 9B is an enlarged sectional view of the metal sintered filter 53. In the present embodiment, the sintered mesh 53 is formed by sintering a plurality of metal meshes having different numbers. This makes it possible to obtain a sintered filter fitting with a precision of 20 fronts. Specifically, the metal sintered network 53 can constitute a five-layer structure 'the protective layer 一般56彳4' having a general mesh exposed on the side of the cylinder 35, followed by the finest filtration control layer 57 for secondary filtration, and secondly In order, the mesh body is thicker and supports f 58 , the mesh body is thicker, the reinforcing layer 59, and the second reinforcing layer 60 of the prescribed mesh are sintered to be integrated. The metal mesh of the metal sintered transition network of 匕 is preferably made of stainless steel on the rust prevention. Here, the sintering is carried out for a certain period of time in a temperature state in which the melting point of the metal is high, and atoms are diffused between the respective points intersecting in the metal phase, and crystals are formed between the bridging points to be completely integrated. The sinter thus obtained has excellent mechanical strength and corrosion resistance, and has a filtering action for removing impurities and a venting action for removing particles therein when air passes. In addition, the sound insulation function of absorbing sound energy can be exerted. The metal sintered filter 53 having the above characteristics is a sophomore

The cover is placed laterally through the through hole 50b to maximize the sound insulation effect. W

Figure 10A of Figure 10 shows the air flow of the raw material supplied to the compressor and the compressed air flow. The main part is cut away as shown in the oblique view; 1〇Β shows the up and down movement of the piston. The generated noise s is blocked and absorbed by the sintered filter fitting 53, and the main portion is cut away from the appearance oblique view β. Referring to FIGS. 6 and 10, when the motor 39 is energized, the crank shaft moves downward. The piston 33 is lowered to the bottom dead center. At this time, the cylinder chamber has a negative pressure state therein, and the first reed valve 45 of the piston 33 is opened by the first cylindrical transition device 52 and the first cylindrical filter 5: the raw material air of the crucible passes through the through hole 5 〇b and fill the cylinder chamber... T. When the person's horse 39 is energized, the crank shaft 42 is moved upward to make the cylinder valve 45 a positive pressure state and the first valve 45 when the piston pressure is closed. Wait until it rises to the top dead center and arrives - the inner re-spring valve 46 is opened, and the compressed air is sent to the line 24c. Repeating = slack motion sends compressed air into two adsorption cartridges. When the piston moves in, the noise generated is interrupted and absorbed by the metal foil 34 200924809 filter 53. Further, even if part of the noise passes through the through hole 50b, it is blocked by the double-arranged cylindrical filters 51, 52, so that the noise does not leak outward. Next, two nut holes 32h are formed in the bottom surface of the main casing 32 to fix the fixing plate 20. The fixing plate 20 is fixed by using a screw that matches the nut hole 32h. Then, in the soundproof chamber 3, the filter assembly 22, which is integrated with the compressor 1, is fixed in a shock-absorbing state via the suspension rubber. 11A is a cross-sectional view showing a state in which the compressor 1 is fixed to the main tank 2 of the small oxygen concentrating device 1; and 11b is a view showing the vibration occurrence state and shock absorption state of the compressor 10. Appearance oblique view. • In Fig. 11, the constituent elements previously described are given the same reference numerals and the description of the filter assembly 22 integrated in the soundproof chamber 3 and the compressor 1 is omitted, and the filter assembly 22 is in the vertical direction. ❹ The upper position and the motor 39 are placed in the position below the vertical direction. Further, the fixing plate 20 is fixed to the front wall surface of the main casing 2 by a brake (damping) spacer 48 such as a soft foamed polyurethane material. As described above, the mounting surface of the main casing 2 and the soundproof chamber 3 is fixed in the vertical direction (Z-axis direction), so that the vibration in the up-down direction along the Z-axis direction and the direction along the z-axis can be effectively suppressed. Vibration in the left and right direction, vibration in the front and rear directions along the x-axis direction, and the resultant vibration. Alternatively, it may be fixed to the compressor 35 200924809 :;: if it is fixed, it is fixed in the opening portion of the soundproof chamber 3, so that the proper slab η absorbs the soundproofing sheet composed of the above-mentioned non-woven fabric and is added to the main ΓΛ The humming sound is absorbed by the sound-insulating sheet. The W-face is suitable for the above-mentioned structure. The small oxygen is concentrated to the compressor 1 〇, the wind flat/earth soil begins to be external S 2 and:: with the second _ ^ 守八 with the air introduction sound, the same connection f The vibration of the 1G of the compressor and the noise accompanying the vibration and the sound of the passage from the pipe connected to each of the adsorption cylinders are continuously generated, but the noise and vibration caused by the leakage of the γ is described. The introduced air enters the first-adsorption cylinder (10)a' via the three-way switching valve 109a, and the oxygen generated by the three-way switching valve (10)a' flows into the product drum 111 through the check valve to gradually increase the pressure. When the set pressure is reached, the equalizing valve is opened in the "open state" setting. time. A portion of the oxygen concentrated by the first adsorption column 108a is used to perform the cleaning operation of the second adsorption tube and is ready to be pressurized for its pressing operation. Next, in order to perform the desorption process of the first adsorption column 108a (discharging nitrogen and moisture) and introducing compressed air into the second adsorption column, 36 200924809 starts the three-way switching valve l〇9a. Oxygen separated by the compressed air flowing into the second adsorption column 10b is introduced into the product drum 111 via a check valve not shown. Subsequently, when the pressure sensor not shown in the figure detects the arrival of the set pressure, the pressure equalizing valve 107 is "on" to open the set time. Subsequently, the cleaning and pressure equalization of the second adsorption column 10 8 t) is performed. When the pressure equalizing valve 1〇7 is turned on as described above, the generated emulsion gas in the second adsorption column 108b 4 is sent to the outlet portion of the first adsorption column 108a, and the sealed zeolite is washed. When the above operations are repeatedly performed for a certain period of time, oxygen supply can be continuously and stably supplied. Further, the flow sensor 116 determines the flow rate of the oxygen flow, and the actual flow rate can be measured in addition to the set value set by the read flow rate to prevent the flow rate due to external factors such as hose folding. • &lt;Explanation of Predictive Breath Synchronization&gt; Referring again to Fig. 4, since the pressure in the product barrel 1 i丨 changes in synchronism with the pressure in the adsorption cylinder, the pressure regulator 112 has a constant pressure ❹ function and contains a filter. (not shown). This filter uses an average diameter of less than i〇〇em to protect the micro-pressure sensor connected to the demand valve 1 π to detect downstream components below the pressure regulator 112 during inhalation. An oxygen concentration sensor 114 is connected to the downstream side of the pressure regulator 112 via a line 24e for detecting the oxygen sensitivity. Further, a proportional opening degree valve 115 is connected via a line 24g which can drive the switch to change the opening. The proportional opening valve 115 is connected to the flow control substrate 202, and the 37 200924809 is configured to drive the switch to change the opening degree in proportion to the oxygen supply amount set by the oxygen flow rate setting mechanism. Specifically, in the present invention, the degree of opening of the electromagnetic valve which simply performs the switching operation is specifically designed to be proportional to the drive voltage value, and the oxygen supply amount can be controlled linearly. Further, 'the downstream side of the proportional opening valve 115 is connected to the oxygen flow rate* sensor 116 to detect the oxygen flow rate; and the downstream side of the oxygen flow sensor 116 is connected to the demand valve 117 to deliver oxygen in response to the inhalation state. The downstream side of the sputum valve 117 is connected to the transition 119, and the oxygen inhaler of the nasal cannula 14 is used for the purpose of inhaling oxygen. The demand valve 117 is connected to a micro pressure sensor controlled by the flow control substrate 2〇2 for detecting a negative pressure during breathing and timely delivering oxygen to the user. In the above configuration, when the set flow rate and the setting synchronization mode are input after the power is turned on, the flow rate is maintained in accordance with the set flow rate. Next, the micro-pressure sensor connected by the proportional opening valve 117 detects the negative pressure at the time of inhalation. Next, the proportional opening valve 117 is activated to supply oxygen. Then, the oxygen flow rate sensor 116 detects the actual flow rate of oxygen, compares the actual flow rate with the set flow rate, and automatically adjusts the opening degree of the proportional opening degree valve i 15 to reach the set flow rate. When the inhalation state is detected by the above micro pressure sensor, the proportional opening degree valve u 5 drives the switch 'in proportion to the oxygen supply amount set by the oxygen flow rate setting mechanism to change the opening degree, and simultaneously inhales oxygen into the breathing chamber by the breathing 38 ❹ 200924809 The most appropriate supply of oxygen. According to the above-described respiratory synchronization control, when the entire oxyhydroxide concentrating device 1 is driven by a rechargeable battery, the patient is controlled to synchronize with the breathing in order to use the concentrated oxygen more efficiently. Usually during breathing, the inspiratory/expiratory cycle of * is set to 1:2, and the exhalation produces = "gas is not needed for the patient. Therefore, excess battery power is provided to provide excess concentrated oxygen. That is, when the squirting squirt is used to inhale the oxygen supply during the exhalation, if the inhalation/beer cycle is set to 1: 2 ', the triple flow p can be supplied during inhalation. (4) Respiratory synchronization control, capable of The advantages of miniaturization and smelting of the oxygen concentrating device. θ ^ 12 circle is the predicted type of respiratory synchronization and continuous generation of oxygen flow 1, control mode, 1G horse rotation number, Li power, exhalation rate may correspond to the oxygen supply The relevant quantity of the quantity is in the circle, the power consumption of the control mode is 127W, and the number of rotations of the motor 39 is 27〇〇 per minute = the flow rate of oxygen is 3 liters, in the ratio of inhalation·exhalation It can supply up to 6 liters per minute for 1:2 = knife knives minus 3 。. 2 'Control mode B consumes electricity for li6 w, and sets horse 7 / 八 for every minute &amp; 25 GG times Continuously generate oxygen flow at a ratio of 1:2 inhalation to exhalation and 2 inhalation of oxygen per minute: 'Up to 7.5 liters per minute. Control mode c consumes 76w of power and sets motor rotation 39 200924809 2 number = 175 times per minute' to continuously produce oxygen rise, in the case of inhalation · exhalation ratio i: 3 and 2 &gt; When it can supply up to 8 metrics per minute: oxygen... Again, the power consumption of control mode D is 1500 times per minute, so that continuous generation of oxygen == horse: and?: force and machine When the number of revolutions is as shown in the second figure, the control mode is stored in the control of the clock mode 1 in the mode clock 1 mode A to F, and the number of rotations can be increased or decreased by a number of rotations, which can reduce the snow *坫釭+我Nisshin Ma violates the levy of A~F. As for the selection of any of the control modes, it is automatically detected by the device. ! In the picture above, it is said that the second pre-/"Shiguo Y' begins to inhale the oxime.

The shortage of oxygen supply is returned to completion. As described above, the oxygen supply cycle is predicted based on the oxygen intake frequency obtained by inhalation and exhalation, and the number of motor rotations of the drive motor is changed corresponding to the predicted oxygen supply amount. The result is that the power consumption and the built-in can be reduced or Consumption of external rechargeable batteries "This way, saving electricity is the most important requirement for portable machines. As described above, the case where the most appropriate control modes A to F are automatically set 'can be automatically set by the degree of use of the device 1 except that the patient's inhaled oxygen state is reflected. That is, because at a higher altitude • Oxygen is thinner, the patient can be used without paying attention to environmental changes when the oxygen supply is increased in height. &lt;Automatic setting of oxygen supply according to Global Positioning System (GPS)&gt; 连接 When the control unit 2 is connected to the global satellite positioning system device 2 2 i. The height of the use place of the measuring device j according to the global satellite positioning system To increase or decrease the number of revolutions of the compressor 10 and change the amount of compressed air. Also, the most appropriate control modes A to F are automatically set to change the air supply amount. The figure illustrates an action flow diagram for increasing the oxygen supply in accordance with the height of the global satellite positioning system measuring device. In this figure, when the device 1 starts, it enters the step of Hua Wei) into the measurement of the global satellite positioning of 200924809 2 . This global health system can measure four points between four people and between satellites and three artificial satellites. = In comparison with the coordinates of the coordinates and the built-in height map in the point measurement, select the four-point measurement or the three-point measurement in step 11 (S11) to select the four-point measurement in step 11 (S11), and enter the step. 12 (S12) Calculate the same degree. If the height is high, increase the number of rotations of the compressor 10 to improve the oxygen concentration. Then, in step φ I4), the motor drive control is terminated and terminated. On the other hand, when the three-point measurement is selected in step U (S11), the process proceeds to step 15 (S15), and if it is determined that the three-point measurement cannot be performed, the process returns to step io(sio)' by the above step 10 (S10). When it is determined in step 15 (S15) that the three-point measurement is performed, the height is determined in step 16 (S16), and the built-in dimension map determines the height, and the number of rotations of the compressor 10 is adjusted correspondingly to the height. Oxygen concentration. Then, in step 14 (S14), motor drive control is performed. ❾ &lt;^ Description of the combined battery 228> • The power supply control circuit 226 is connected to the ID identifier code recognition circuit 230 in Fig. 4, and it is possible to prevent the battery power from being exhausted while being carried, and to charge at the same time. The battery 228 is disposed in an overlapping state and freely exchanged from the lower side of the main casing 2, so that the low center of gravity of the device 1 is also as described above. In order to prevent the battery from being exhausted when carrying, it is conceivable to connect a plurality of batteries. Rechargeable batteries 228, ..., 228. However, when multiple batteries are connected to 200924809, the power conversion method will be complicated and the power consumption cannot be individually measured.
