Embodiments of the present invention relate to an automatic oxygen supply device, method, and computer program.

In general, respiratory arrest occurs due to various causes, such as central paralysis, electroshock, intracranial pressure improvement, cerebral trauma, cervical spinal disorder, airway obstruction, and oxygen administration to patients with hypercapnia. In this case, in order to prevent brain disorders due to lack of oxygen, rapid treatment is necessary as much as possible. The essential use is to supply oxygen to the body lacking oxygen, and the first aid kit is used at this time. An emergency resuscitation bag is a resuscitation device with a relatively simple mechanism used for first aid clinical use, and there are various types of cases, such as attaching an attached valve to the bag. O2 flow is connected to an emergency resuscitation bag to perform oxygen inhalation. These measures are performed promptly after an accident because the functions of tissues, especially the heart and brain, are severely impaired in a short time due to oxygen deficiency. In addition, oxygen intake is carried out for the purpose of preventing these, as an adverse reaction to the living body occurs due to insufficient oxygen. It is applied when there is a decrease in blood flow due to ischemic disease, shock, etc., and when there is pulmonary dysfunction or pre-oxygenation in high acid. If the arterial oxygen saturation is less than 85% and the arterial oxygen partial pressure is less than 50 mmHg, it is an absolute indication for oxygen therapy. In the first-aid resuscitation method, a suitable mask suitable for the patient's mouth size is connected to the valve, and the air bag is squeezed by adjusting the amount and speed according to the air volume (oxygen amount) required by the patient. According to this purpose, the amount of air and the speed of inhalation of an emergency resuscitation bag used have emerged as an important factor in saving lives.

Effects and features of the present invention and methods for achieving them will be clarified with reference to embodiments described below in detail together with the drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various forms.

A conventional automatic oxygen supply device inhales oxygen manually and injects the inhaled oxygen to a user. It is very difficult to continuously inject oxygen into a patient who cannot breathe on a continuous breathing cycle.

The automatic oxygen supply device according to the embodiments of the present invention may operate automatically in order to draw the patient's self-breathing. 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 breathing cycle, breathing capacity, etc. are set. The automatic oxygen supply device according to the embodiments of the present invention can control the patient to be supplied with oxygen with a respiratory cycle and a respiratory capacity calculated according to a patient's height, heart rate, age, and gender. The automatic supply device according to the embodiments of the present invention uses the history data such as the operated breathing cycle and the breathing capacity to determine the breathing cycle and breathing capacity of the corresponding patient, and provides oxygen to the patient with the breathing cycle and the breathing capacity. It can be controlled to be supplied.

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 Figure 1a, the automatic oxygen supply device 100, in order to supply oxygen to the patient in an emergency situation in which breathing difficulty occurs, taking into account the actual condition of the user comprehensively, the supply oxygen amount calculation unit for calculating the supply oxygen amount (120), an oxygen supply unit 130 that controls the supply of oxygen that matches the supply oxygen amount, an injection amount calculation unit 140 for calculating the amount of injected oxygen sucked by the user, an information output unit 160 for outputting information, and a supply The oxygen amount calculating unit 120, the oxygen supply unit 130, the injection amount calculating unit 140, and the information output unit 160 may be provided with a control unit 110 for overall control of operations.

According to the present specification, the automatic oxygen supply apparatus 100 may allow the oxygen supply to the emergency patient, which was manually performed, to be mechanically supplied with oxygen. In addition, the automatic oxygen supply device 100 may be implemented to perform an oxygen supply function relatively inexpensively compared to an expensive oxygen supply device used in the intensive care unit and the emergency room. In addition, the automatic oxygen supply device 100 may monitor the amount of injected oxygen that is actually injected into the user in order to prevent the life of the patient having difficulty breathing from becoming serious. The automatic oxygen supply device 100 may be appropriately injected with oxygen without leaking oxygen to the user. The supply oxygen amount calculating unit 120 may calculate a 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 patient's breathing state.

The amount of oxygen supplied may be changed in consideration of the time when oxygen starts to be supplied. For example, in the first section in which oxygen is supplied before the patient's height, age, gender, and lung capacity are sensed, the amount of oxygen supplied may be calculated as a default value. That is, in the first section, the amount of oxygen supplied is set without considering the user's height, age, gender, vital information such as lung capacity, and the like. In the second section after the preset first section, the amount of oxygen supplied may be calculated using the user's biological information (gender, age, heart condition, etc.). The amount of oxygen supplied may be generated and stored in a table including the amount of oxygen required in relation to gender, age, and heart condition. The table including the relationship between bio-information and oxygen demand is received and stored only once, and may be partially updated. Through this, it is possible to ensure that the user is supplied with proper oxygen at an appropriate cycle. In addition, an excessive amount of oxygen is supplied irrespective of the user's breathing ability, thereby preventing the user's condition from deteriorating. Through this, the automatic oxygen supply device 100 may be implemented so that the patient's breathing is maintained 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 supplied oxygen amount calculated using the user's biological information. As a result of monitoring, when the amount of oxygen to be injected is smaller than the amount of oxygen to be supplied, the amount of oxygen supplied may be recalculated. Since the amount of injected oxygen is smaller than the amount of oxygen supplied, leakage occurs during the process of being delivered to the user, and in order to deliver oxygen as much as the amount of oxygen supplied to the user, it is necessary to supply oxygen more than the calculated amount of oxygen supplied. To this end, the amount of oxygen supplied may be increased than the amount of oxygen supplied in the second section. Through this, it is possible to self-diagnose the problem that oxygen is not supplied to the user due to a problem in the device. Through this, due to the nature of the emergency patient, which may affect the patient's life, the defect of the device can be monitored in real time.

The oxygen supply unit 130 controls the amount of supply oxygen calculated by the supply amount calculation unit 120 to be properly delivered to a passage connected to the user. The oxygen supply unit 130 may include an oxygen supply control unit 131 that adjusts to be supplied as much as the amount of supply oxygen calculated by the supply oxygen amount calculation unit 120.

The container of the oxygen supply unit 130 may be designed as a syringe type or a bellows type, but is not limited thereto. By adjusting the capacity of the container by the oxygen supply adjusting unit 131, it is possible to control the calculated supply oxygen amount to be supplied. At this time, the capacity of the container may be manually adjusted by the user. The oxygen supply control unit 131 may be designed by a combination of a syringe and a piston, and by adjusting the position of the piston, the amount of oxygen supplied may be changed. For example, when the amount of oxygen supplied is 150 cc, the position of the piston may be placed in a first position corresponding to 150 cc. When the amount of oxygen supplied is 300 cc, the position of the piston may be placed at a second position that is twice as far as the first position corresponding to 300 cc. The amount of oxygen supplied can be changed as the position of the piston moves closer or closer.

The oxygen supply control unit 131 may be controlled to supply the amount of supply oxygen that is designed and calculated by using a string type or an actuator that adjusts the size of the oxygen supply unit 130 designed as an oxygen supply bag. By adjusting the length of the string or the actuator, such as long or short, the capacity of the supply unit 130 can be adjusted. Through this, the amount of oxygen supplied may be changed as the cross-sectional area decreases according to the length of the string.

At this time, the correlation between the amount of oxygen supplied and the length of the string 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 length of the oxygen supply bag, it is possible to calculate the length of the string corresponding to the amount of oxygen supplied. Therefore, the volume of the amount of oxygen supplied may be changed according to a change in length of a string or an 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 an oxygen supply cycle according to a user's breath. The oxygen supply unit 130 controls the amount of oxygen supplied to the user according to the oxygen supply cycle. The oxygen supply cycle can be dynamically changed to lengthen or shorten as the user's breathing gets worse or slower. The oxygen supply unit 130 may measure a user's blood oxygen saturation degree, injection flow rate, EtCO2, and injection pressure by using a sensing value sensed from an injection mask or a sensor attached to the 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 tube connected to the user's mouth. For example, if the change in oxygen saturation in the blood 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 may be started according to the determination. Can. 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 time points.

When the amount of oxygen injected is close to the amount of oxygen to be supplied (for example, 90% or more), a new oxygen supply is controlled. Or, when the injection pressure is almost 0, for example, less than 10% of the maximum pressure, a new oxygen supply is controlled.

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

The injection mask 141 is configured to cover the user's mouth and nose, and the portion in contact with the user's skin may be made of a material having adsorption power to prevent oxygen leakage. The injection mask 141 injects oxygen through the hose connected to the oxygen supply unit 130 into the user's mouth and nose according to air rotation through one or more internal spiral blades 140f. Oxygen may be induced to flow in a predetermined direction through a plurality of internal spiral wings located around the hose connected to the injection mask 141. The flow of oxygen can be controlled by the rotation of the inner spiral wings. The injection mask 141 detects changes in the patient's condition by detecting changes in the pressure sensor or flow rate, oxygen saturation, and ETCO2.

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 level in the blood, the supply cycle, ETCO2, etc. every oxygen supply cycle. The amount of oxygen supplied, the amount of oxygen injected, or the pressure of injection, the degree of oxygen saturation in the blood, the supply cycle, ETCO2, etc. can be recorded cumulatively.

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 bio signal after oxygen is supplied to the patient and change the oxygen supply cycle accordingly. For example, if the patient's biosignal does not improve even with oxygen supply, the oxygen supply cycle of the patient may be adjusted to the time before and after according to a preset manual. If the patient's vital signal is improved due to the oxygen supply, the patient's oxygen supply cycle is fixed and controlled to operate.

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

As shown in FIG. 2, the oxygen supply unit 130 controls the 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 given volume of oxygen can be delivered to the injection mask. In another embodiment, the oxygen supply unit 130 may receive air from the atmosphere, that is, air. In accordance with the patient's breathing cycle, the time periods of oxygen supply and infusion can be configured to cross each other. For example, when an oxygen supply section in which oxygen is supplied from the oxygen tank passes, an oxygen injection time in 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 provide the oxygen to the user during the second time t2. Infuse At this time, the second entrance may be closed during the first time t1, and the first entrance may be closed during the second time t2. Since the supply amount per hour of the supply device is controlled by the machine, the first time t1 can be shortened.

The oxygen supply unit 130 and the oxygen supply control unit 131 of FIG. 2 may be designed in a syringe or bellows type. The oxygen supply control unit 131 may be configured with a clip that adjusts the maximum capacity of the syringe. The oxygen supply unit 130 receives oxygen from the oxygen tank 200. At this time, the oxygen supply unit 130 controls to be supplied to the user at a time as much as the supply oxygen amount calculated by the supply oxygen amount calculation unit 20. The oxygen supply unit 130 is implemented with a syringe or 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 unit 130 moves oxygen through the second inlet and injects it to the user. The supply volume adjustment is implemented by a flow rate control lever, etc., and controls the amount of air or oxygen supplied by rotating the flow rate control lever.

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

Referring to Figure 3a, the oxygen supply control unit 131' may be implemented in the form of a bellows. The automatic oxygen supply device 100 further includes an oxygen supply control unit 131' for determining the amount of oxygen to be supplied, and an oxygen supply control unit 132' for adjusting the position of the oxygen supply control unit 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 string connected to the oxygen supply control unit 131' to determine the maximum capacity. When the two handles included in the oxygen supply control unit 132' are grasped, 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 the two handles included in the oxygen supply control unit 132', oxygen can be controlled to be injected into the user at a cycle that matches the user's breathing cycle.

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 control unit 131 may adjust the maximum size of the bellows, thereby adjusting the capacity of oxygen injected into the patient. In addition, the oxygen supply control 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 control unit 131 ″ may be implemented in the form of a band or string that adjusts the volume of the oxygen supply unit 130. As shown in FIG. 4, the oxygen supply control unit 131 ″ is implemented as a band or a string surrounding the circumference of the oxygen supply unit 130, and adjusts the capacity of the oxygen supply unit 130 by adjusting the length of the band or string and adjusts the oxygen The amount of oxygen supplied may be adjusted according to the capacity of the supply unit 130. For example, the oxygen supply control unit 131 ″ searches the length of the line corresponding to the amount of oxygen supplied by the supply oxygen calculator 120 and decreases or increases the length of the line by the length of the corresponding line. . Through this, the capacity of the oxygen supply unit 130 is reduced or increased by the amount of oxygen supplied. The length of the corresponding row can be retrieved using a look-up table or calculated in correspondence with the oxygen supply amount.

As shown in FIG. 4B, when the two handles included in the oxygen supply control unit 132” are grasped, the length of the string of the oxygen supply control unit 131” is shortened, and the capacity of the oxygen supply unit 130 is reduced. Will decrease.

That is, as shown in FIG. 4C, the capacity calculated by the cross-sectional area (s) and length (L) of the oxygen supply unit 130 can be matched with the amount of oxygen supplied. As shown in FIG. 4D, the length of the string and the amount of oxygen supplied may have a relationship. Using the relational expression of FIG. 4D, it is possible to search the length of the line corresponding to the amount of oxygen to be supplied.

5 is a view for explaining the injection mask 141 attached to the user.

Referring to FIG. 5, a sensor 142 such as a flow rate (blood oxygen saturation, pressure) ETCO2 for measuring the flow of air injected to the user may be attached to the injection mask 141. The flow of air injected to the user is calculated using one or more sensors 142, and it is determined whether oxygen to be actually supplied is supplied. Additionally, the automatic oxygen supply device 100 may be connected to a biosignal detector (not shown) to receive the biosignal of the user.

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 user's biosignal, and control the oxygen to be supplied to the user who is the patient. Since it can be applied to users who have difficulty breathing, the amount of oxygen supplied is controlled according to the frequency and frequency of breathing by the user.

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 can compare the supply oxygen amount and the injected oxygen amount. In S230, when the amount of oxygen supplied exceeds the amount of injected oxygen, the automatic oxygen supply device determines that the amount of oxygen to be supplied to the user is not actually injected. The automatic oxygen supply device recalculates the supply oxygen amount using the difference between the injected oxygen amount and the supplied oxygen amount. The automatic oxygen supply device can recalculate the supply oxygen amount by adding a certain percentage of the difference value, for example, 70%, to the supply oxygen amount. Through this, the automatic oxygen supply device controls to smoothly supply oxygen necessary for extending the life of the user. In addition, the automatic oxygen supply device, even if oxygen is not supplied due to a defect in the device, despite the occurrence of oxygen, the oxygen supply previously calculated so that the oxygen supply before the replacement with the new oxygen supply is made again Can be calculated once. The automatic oxygen supply device can generate a message including that there is an outflow of oxygen and deliver it to the manager.

In S240, the automatic oxygen supply device is monitored by calculating the amount of injected oxygen at every breathing cycle. The automatic oxygen supply device may calculate the amount of injected oxygen using a flow sensor that measures the flow of air in the injection mask. The flow sensor is attached to the injection mask side and measures 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 when it is determined that the outflow of air is generated, the supply oxygen amount is reset so as not to be a threat to the user's life until the problem is solved. Can be calculated.
