However, the present invention is not limited to the embodiments disclosed below but may be implemented in various forms.

The conventional automatic oxygen supply device inhales oxygen manually and injects the inhaled oxygen into a user. It is very difficult to continuously inject oxygen in the breathing cycle to patients who cannot breathe self.

The automatic oxygen supply device according to embodiments of the present invention can operate automatically to elicit a patient's self breath. In addition, the automatic oxygen supply device according to embodiments of the present invention can be controlled to be supplied to the patient as the respiratory cycle, respiratory capacity, etc. are set. The automatic oxygen supply device according to the embodiments of the present invention may control oxygen to be supplied to the patient with a breathing cycle and a breathing capacity calculated according to the patient's height, cardiac volume, age, gender, and the like. The automatic supply apparatus according to the embodiments of the present invention determines the breathing cycle and the breathing volume of the patient's personalization using history data such as the operated breathing cycle and the breathing volume, and oxygen is supplied to the patient with the breathing cycle and the breathing volume. Can be controlled to be supplied.

Figure 1a is a block diagram showing the structure of an automatic oxygen supply device 100 according to embodiments of the present invention.

As shown in FIG. 1A, the automatic oxygen supply device 100 calculates a supply oxygen amount calculating a supply oxygen amount by comprehensively considering an actual state of a user in order to supply oxygen to a patient in an emergency situation in which breathing difficulty occurs. 120, an oxygen supply unit 130 controlling to supply oxygen corresponding to the supply oxygen amount, an injection amount calculation unit 140 for calculating an injection oxygen amount sucked by a user, an information output unit 160 for outputting information, and a supply The controller 110 may be configured to control overall operations of the oxygen amount calculating unit 120, the oxygen supply unit 130, the injection amount calculating unit 140, and the information output unit 160.

According to the present specification, the automatic oxygen supply device 100 may mechanically supply oxygen to an emergency patient that was manually made. In addition, the automatic oxygen supply device 100 may be implemented to perform the oxygen supply function relatively inexpensively compared to the expensive oxygen supply device used in the intensive care unit, emergency room. In addition, the automatic oxygen supply device 100 may monitor the amount of injected oxygen actually injected to the user in order to prevent the life of the patient who is difficult to breathe. The automatic oxygen supply device 100 may be appropriately injected with oxygen without leakage of oxygen to the user. The supply oxygen amount calculating unit 120 may calculate the supply oxygen amount to be supplied to a user having difficulty in self breathing. The supply oxygen amount calculating unit 120 may calculate the supply oxygen amount to be supplied to the user step by step in consideration of the breathing state of the patient.

The amount of supplied oxygen can be changed in consideration of the time at which oxygen starts to be supplied. For example, the supply oxygen amount may be calculated as a default value in the first section in which the oxygen supply is performed before the detection of the patient's height, age, sex, and lung capacity. That is, in the first section, the supply oxygen amount is set without considering biometric information such as height, age, gender, and lung capacity of the user. In the second section after the preset first section, the supply oxygen amount may be calculated using biometric information (gender, age, heart state, etc.) of the user. The supply oxygen amount may be generated and stored in a table that includes oxygen needs associated with gender, age, heart condition, and the like. The table containing the relationship between the biometric information and the oxygen requirement is received and stored once and may be partially updated. Through this, the user may be supplied with the appropriate oxygen at an appropriate cycle. In addition, irrespective of the user's breathing ability, an excessive amount of oxygen may be supplied to prevent the user's condition from deteriorating. Through this, the automatic oxygen supply device 100 may be implemented to maintain the breathing of the patient more accurately in consideration of the patient's biometric information while allowing oxygen to be supplied to the patient.

The automatic oxygen supply device 100 may monitor a difference value between the supply oxygen amount and the injected oxygen amount during the second period of controlling to supply the supply oxygen amount calculated using the biometric information of the user. As a result of the monitoring, when the injected oxygen amount is smaller than the supplied oxygen amount, the oxygen supply amount can be recalculated. Since the amount of injected oxygen is smaller than the amount of supply oxygen, leakage occurs during the process of being delivered to the user. Therefore, in order to deliver oxygen as much as the amount of supply oxygen to the user, it is necessary to supply more oxygen than the calculated amount of supply oxygen. To this end, the supply oxygen amount may increase than the supply oxygen amount calculated in the second section. This makes it possible to self-diagnose the problem that oxygen is not supplied to the user due to problems in the device. Through this, due to the characteristics of the emergency patient that can affect the patient's life, it is possible to monitor the defect of the device in real time.

The oxygen supply unit 130 controls the supply oxygen amount calculated by the supply amount calculating unit 120 to be appropriately delivered to the passage connected to the user. The oxygen supply unit 130 may include an oxygen supply control unit 131 that adjusts the supply of oxygen by the supply oxygen amount calculated by the supply oxygen amount calculation unit 120.

The vessel of the oxygen supply unit 130 may be designed as a syringe type or bellows type, but is not limited thereto. By adjusting the capacity of the container by the oxygen supply control unit 131, it is possible to control so that the calculated supply oxygen amount is supplied. At this time, the capacity of the container may be manually adjusted by the user. The oxygen supply controller 131 may be designed by combining the syringe and the piston, and by adjusting the position of the piston, the supply oxygen amount may be changed. For example, if the supply oxygen amount is 150cc, the position of the piston may be placed in a first position corresponding to 150cc. When the supply oxygen amount is 300 cc, the position of the piston may be placed in a second position two times apart from the first position corresponding to 300 cc. The amount of oxygen supplied can change as the piston moves closer or closer to its position.

The oxygen supply controller 131 may control the supply oxygen amount, which is designed and calculated by using a string type or an actuator to adjust the size of the oxygen supply unit 130 designed as the oxygen supply bag, to be supplied. By adjusting the length of the string or the actuator to be long or short, the capacity of the supply unit 130 can be adjusted. This allows the amount of supplied oxygen to change as the cross-sectional area decreases with the length of the cord.

In this case, the correlation between the capacity of the supply oxygen amount and the length of the joule or the actuator may be measured experimentally and stored in a table. By calculating the volume of the oxygen supply bag using the cross-sectional area and the length of the oxygen supply bag, the length of the string corresponding to the supply oxygen amount can be calculated. Therefore, the volume of the supplied oxygen amount can be changed in accordance with the change in the length of the joule or the actuator.

The oxygen supply unit 130 may adjust the oxygen supply cycle as well as the amount of oxygen supplied. The oxygen supply unit 130 may determine the oxygen supply cycle according to the user's breathing. The oxygen supply unit 130 controls the oxygen as much as the supply oxygen amount to be provided to the user according to the oxygen supply cycle. The oxygen supply cycle may be dynamically changed to become longer or shorter as the user's breathing becomes slower or slower. The oxygen supply unit 130 may measure a blood oxygen saturation degree, an injection flow rate, an EtCO 2, and an injection pressure using a sensing value sensed by a sensor attached to an injection mask or a main body. The oxygen supply unit 130 may calculate an oxygen supply frequency or an oxygen supply cycle using an injection amount and an injection pressure measured through a pipe connected to a user's mouth. For example, if the change in blood oxygen saturation according to the injection pressure of FiO2 in the injection mask to the user does not reach the predicted value, it is determined that a new oxygen supply is necessary, and the oxygen supply starts according to the determination. Can be. That is, the oxygen supply unit 130 may acquire time points when the injection pressure of oxygen is less than 10% of the maximum injection pressure, and determine the oxygen supply cycle using the points.

When the injected oxygen amount is almost close to the supply oxygen amount (for example, 90% or more), a new oxygen supply is controlled. Or when the inlet pressure is near zero, for example less than 10% of the maximum pressure, a new oxygen supply is controlled.

The injection oxygen amount calculating unit 140 may measure the injection oxygen amount injected to the user in order to determine whether oxygen is properly injected to the user. The injection oxygen amount calculation unit 140 may receive flow rate information from a flow rate sensor attached to or included in the injection mask or the main body. The injection oxygen amount calculating unit 140 may measure the injection oxygen amount of the user using flow rate information.

The injection mask 141 has a structure covering the user's mouth and nose, and may be made of a material having an adsorption force on a part of the user's skin to prevent oxygen leakage. The injection mask 141 injects oxygen into the user's mouth and nose as the air rotates through one or more internal spiral blades 140f through a hose connected to the oxygen supply 130. Oxygen may be induced to flow in a predetermined direction through a plurality of inner spiral blades positioned around a hose connected to the injection mask 141. The rotation of the inner spiral blades regulates the flow of oxygen. The injection mask 141 detects a change in a pressure sensor or a flow rate, oxygen saturation, ETCO2, or the like to detect a change in a patient's condition.

The information output unit 160 may display the supply oxygen amount, the injected oxygen amount, and the current state of the user. The information output unit 160 may provide the amount of oxygen supplied to the user, the amount of oxygen injected, the injection pressure, the oxygen saturation in the blood, the supply cycle, and the ETCO2 in every oxygen supply cycle. Supply oxygen amount, injection oxygen amount, or injection pressure, blood oxygen saturation, supply cycle, ETCO2 and the like can be recorded cumulatively.

As shown in FIG. 1B, the automatic oxygen supply device 100 may be operated in connection with the biosignal detector 300. The automatic oxygen supply device 100 may automatically receive a biosignal after oxygen is supplied to the patient and change the oxygen supply cycle accordingly. For example, if the patient's biological signal does not improve even with oxygen supply, the oxygen supply cycle of the patient may be adjusted back and forth according to a preset manual. If the oxygen supply improves the patient's vital signs, the patient's oxygen supply cycle is fixed and controlled to operate.

2 is a view for explaining various embodiments of the automatic oxygen supply device according to the embodiments of the present invention.

As shown in FIG. 2, the oxygen supply unit 130 controls opening and closing of the first inlet for the passage connected to the oxygen supply device 200 and the second inlet for the passage connected to the injection mask, thereby providing the oxygen supply device 200. A predetermined dose of oxygen from) may be delivered to the injection mask. In another embodiment, the oxygen supply unit 130 may receive air from the atmosphere, that is, air. Depending on the breathing cycle of the patient, the time intervals of oxygen supply and infusion can be configured to cross each other. For example, after an oxygen supply interval in which oxygen is supplied from an oxygen cylinder, an oxygen infusion time at which oxygen is delivered to the patient is arranged. As shown in FIG. 8, the first inlet is opened to receive oxygen during the first time t1 of the user's (patient's) breathing cycle, and the second inlet is opened to open the oxygen to the user during the second time t2. Inject. In this case, the second inlet may be closed during the first time t1, and the first inlet may be closed during the second time t2. The first time t1 can be shortened because the feeding amount per hour of the feeding device is controlled by the machine.

The oxygen supply unit 130 and the oxygen supply control unit 131 of FIG. 2 may be designed in the form of a syringe or bellows. The oxygen supply controller 131 may be configured as a clip for adjusting the maximum capacity of the syringe. The oxygen supply unit 130 receives oxygen from the oxygen cylinder 200. At this time, the oxygen supply unit 130 controls the supply oxygen amount calculated by the supply oxygen amount calculation unit 20 to be supplied to the user at one time. The oxygen supply unit 130 is implemented with a syringe or a bellows, and by adjusting the position of the piston, it is possible to change the amount of oxygen supplied at one time. The oxygen supply 130 moves oxygen through the second inlet and injects the oxygen into the user. Supply volume adjustment is implemented by a flow control lever, etc., and adjusts the amount of air or oxygen supplied by rotating the flow control lever.

3A and 3B are diagrams for describing an embodiment of an oxygen supply unit.

Referring to FIG. 3A, the oxygen supply controller 131 ′ may be implemented in a bellows shape. The automatic oxygen supply device 100 further includes an oxygen supply controller 131 ′ for determining a capacity of oxygen to be supplied, and an oxygen supply controller 132 ′ for adjusting the position of the oxygen supply controller 131 ′. It may further include. The oxygen supply control unit 132 'adjusts the capacity of the oxygen supply unit 130' by adjusting the length of the cord connected to the oxygen supply control unit 131 'that determines the maximum capacity. When the two handles included in the oxygen supply control unit 132 'are gripped, the length of the string connected to the oxygen supply control unit 131' is reduced, and as a result, the capacity of oxygen to be supplied is reduced.

Through two handles included in the oxygen supply controller 132 ′, oxygen may be injected to the user at a cycle that matches the breathing cycle of the user.

The oxygen supply unit 130 and the oxygen supply control unit 131 of FIG. 3 may be designed in a bellows type. The oxygen supply controller 131 may adjust the dose of oxygen injected into the patient by adjusting the maximum size of the bellows. In addition, the oxygen supply adjusting unit 131 may supply oxygen to the patient by expanding or contracting the bellows.

4A, 4B, 4C, and 4D are views for explaining another embodiment of the oxygen supply control unit.

Referring to FIG. 4A, the oxygen supply controller 131 ″ may be implemented in the form of a band or a string for adjusting the volume of the oxygen supply 130. As shown in FIG. 4, the oxygen supply adjusting unit 131 ″ is implemented as a band or a string surrounding the oxygen supply unit 130, and adjusts the capacity of the oxygen supply unit 130 by adjusting the length of the band or the string and oxygen. The amount of supply oxygen may be adjusted according to the capacity of the supply unit 130. For example, the oxygen supply controller 131 ″ searches for the length of the string corresponding to the amount of oxygen supplied by the supply oxygen calculator 120, and decreases or increases the length of the string by the length of the corresponding string. . Through this, the capacity of the oxygen supply unit 130 is reduced or increased by the amount of supply oxygen. The length of the corresponding row may be retrieved using a lookup table or calculated in correspondence with the oxygen supply.

As shown in FIG. 4B, when the two handles included in the oxygen supply controller 132 ″ are gripped, the length of the string of the oxygen supply controller 131 ″ is shortened, and the capacity of the oxygen supply 130 is increased. Will be reduced.

That is, as illustrated in FIG. 4C, the capacity calculated by the cross-sectional area s and the length ㅣ of the oxygen supply unit 130 may correspond to the supply oxygen amount. As shown in FIG. 4D, the length of the cord and the amount of supply oxygen may have a relationship. Using the relationship of FIG. 4D, the length of the string corresponding to the amount of supply oxygen to be supplied can be retrieved.

5 is a diagram for describing an injection mask 141 attached to a user.

Referring to FIG. 5, a sensor 142 such as a flow rate (blood oxygen saturation, pressure) ETCO 2 for measuring the flow of air injected into a user may be attached to the injection mask 141. One or more sensors 142 may be used to calculate the flow of air injected into the user and determine whether oxygen to be supplied is actually supplied. Additionally, the automatic oxygen supply device 100 may be connected to a biosignal detector (not shown) to receive a biosignal of a user.

6 and 7 are flowcharts of an automatic oxygen supply method according to an embodiment of the present invention.

As shown in FIG. 6, in S110, the automatic oxygen supply device obtains a biosignal from a biosignal detection apparatus.

In S120, the automatic oxygen supply device may calculate the supply oxygen amount using a biosignal from a separate biosignal detector.

In S130, the automatic oxygen supply device transmits a control signal to the oxygen supply unit so that the supply oxygen amount is injected. By the control signal, the dose adjusting portion is adjusted to have a capacity equal to the amount of supply oxygen.

In S140, the oxygen supply unit of the automatic oxygen supply device receives the supply oxygen amount for the first time through the first inlet.

Through this, the automatic oxygen supply device may calculate the supply oxygen amount in consideration of the biosignal of the user, and control the oxygen supply as much as the calculated supply oxygen amount to be supplied to the patient. Since it can be applied to a user having difficulty breathing, the amount of oxygen supplied is controlled according to the user's breathing cycle and frequency.

As shown in FIG. 7, in S210, the automatic oxygen supply device compares the supply oxygen amount and the injected oxygen amount.

In S220, the automatic oxygen supply device may compare the supply oxygen amount and the injected oxygen amount. In S230, when the supply oxygen amount exceeds the injection oxygen amount, the automatic oxygen supply device determines that the oxygen amount to be supplied to the user is not actually injected. The automatic oxygen supply device recalculates the supply oxygen amount using the difference value between the injected oxygen amount and the supply oxygen amount. The automatic oxygen supply device can recalculate the supply oxygen amount by adding a certain ratio of the difference value, for example, 70% to the supply oxygen amount. Through this, the automatic oxygen supply device controls to smoothly supply the oxygen necessary for extending the life of the user. In addition, the automatic oxygen supply device resets the supply oxygen amount previously calculated so that oxygen supply is made before replacement with a new oxygen supply device, even though oxygen leakage occurs when oxygen is not supplied due to a defect in the apparatus. It can be calculated once. The automatic oxygen supply device can generate and deliver a message to the manager that includes the outflow of oxygen.

In S240, the automatic oxygen supply device monitors by calculating the injected oxygen amount at every breathing cycle. The automatic oxygen supply device may calculate the injected oxygen amount using a flow sensor that measures the flow of air to the injection mask. The flow sensor is attached to the injection mask to measure the amount of air sucked into the user.

Through the above process, the automatic oxygen supply device monitors whether the supply oxygen amount is delivered to the user, and if it is determined that the air leakage occurs, the supply oxygen amount is reset so that it does not pose a threat to the user's life until the problem is solved. Can be calculated.
