Description

Carbon dioxide measuring device connected to a tube for tracheal intubation, its control method and system

The present invention relates to a carbon dioxide measuring device connected to a tube for tracheal intubation, and a control method and system thereof.

Tracheal intubation is a procedure to secure an airway by inserting a tube into the trachea of a patient who needs airway maintenance or ventilator treatment. By maintaining the airway, ventilation and oxygenation are efficiently performed, so that effective suction and rescue medication can be administered through the airway. It cannot be performed on patients who cannot move their neck, and it may cause discomfort and instability because the tube is inserted into the respiratory tract. Tracheal intubation is performed when general anesthesia is required or in emergency situations. It is mainly performed in cases of cardiac arrest, respiratory failure, severe upper airway obstruction, head and neck injury, severe facial burns, or intratracheal aspiration of gastric contents.

The procedure involves first observing the airway using a laryngoscope with the patient lying supine, with the neck bent forward and the head tilted back, and then a tube for tracheal intubation is inserted. Confirm that the position of the tube is appropriate and secure the tube for tracheal intubation. In order to minimize pain during the procedure and ensure safe tracheal intubation, analgesics, sedatives, or muscle relaxants are used before the procedure, but in emergencies or situations where sedation is not available, drugs may not be used. The probability of success is about 90% or more, including the case of multiple attempts, and the procedure takes about 5 minutes, but it may change depending on the procedure progress. During the procedure, depending on the patient's condition, the procedure method may inevitably be changed or the range of the procedure may be added.

During tracheal intubation, local injury to the lips, gums, tongue, pharynx, vocal cords, airway, and teeth, aspiration of gastric contents, intraesophageal intubation, laryngeal spasm, hypoxia, hemorrhage, myocardial infarction, arrhythmias, pneumothorax, sedatives or muscle relaxants Toxicity, cardiac arrest, respiratory failure, etc. may occur, and in such cases, immediate first aid is performed by the medical staff in charge. After tracheal intubation, glottal edema, tracheomalacia, tracheal stenosis, etc. may occur, and tracheostomy may be required if tracheal intubation is to be maintained for a long period of time. If the course of the disease worsens during ventilator treatment after tracheal intubation, extubation may be difficult, and in this case, consultation with the hospital ethics committee may be necessary. Complications that may occur during tracheal intubation include the insertion of a tube that is detached from the trachea, damage to the airway during the intubation process, physical reflexes caused by stimulation of the tracheal intubation, or abnormal intubation function.

Such tracheal intubation is a difficult procedure (medical procedure) performed in an emergency situation, and if it fails, it may pose a threat to the survival and safety of the patient. Recently, a video laryngoscope is used for tracheal intubation, but there are cases where intubation is performed into the esophagus. Therefore, accurate procedures are important during tracheal intubation, but rapid recognition of esophageal intubation when it occurs is also important. For this reason, it should be possible to quickly, objectively and intuitively confirm whether tracheal intubation has been performed accurately.

However, in the prior art, it is difficult to be certain of accurate intubation into the airway before auscultation after intubation. In addition, the auscultation itself also has a disadvantage in that ambient noise or subjective judgment of the operator is included, and time consumption is large. In addition, if there is no certainty even after auscultation, end-tidal CO2 measurement is performed, which takes more time.

The trachea and esophagus have different measured CO2 partial pressures. Normally, the carbon dioxide partial pressure measured in the esophagus is less than 10 mmHg, and the carbon dioxide partial pressure measured in the normal airway exceeds 20 mmHg. If the partial pressure of carbon dioxide in the airway is 10 to 20 mmHg, the tube for tracheal intubation is intubated into the airway, and there may be a physical abnormality such as hypotension or cardiac arrest, or it may be normal.

According to one embodiment of the present application, when there are a plurality of carbon dioxide sensors 110 provided around the carbon dioxide measuring device 100 or the tube 200 for tracheal intubation, the determination unit 121 determines the plurality of carbon dioxide sensors 110 By comparing the measured carbon dioxide levels, only the largest level of carbon dioxide can be determined, and the remaining levels of carbon dioxide can be deleted.

According to one embodiment of the present application, when there are a plurality of carbon dioxide sensors 110 provided around the carbon dioxide measuring device 100 or the tube 200 for tracheal intubation, the determination unit 121 determines the plurality of carbon dioxide sensors 110 By assigning weighted priority to the carbon dioxide levels, the carbon dioxide levels measured by the plurality of carbon dioxide sensors 110 are compared, and only the level of carbon dioxide measured by the carbon dioxide sensor 110 having the highest weight priority is set as the level of carbon dioxide, and the rest of the carbon dioxide levels level can be deleted.

FIG. 3 is a diagram schematically illustrating a display of the carbon dioxide measuring device 100 in a situation in which the tube 200 for tracheal intubation is incorrectly intubated into the body of a subject (patient) according to an embodiment of the present disclosure.

Referring to FIG. 3, the tube 200 for tracheal intubation is intubated into the body of the subject (patient), and the end-tidal carbon dioxide partial pressure in the airway is usually 10 mmHg or more, so the carbon dioxide sensor 110 measures the level of carbon dioxide. When the level of carbon dioxide is measured to be 4 mmHg, the determination unit 121 determines that the tracheal intubation tube 200 is intubated into the esophagus, and the display unit 122 displays it on the display provided in the carbon dioxide measuring device 100. there is. When the determination result is displayed on the display, it may be displayed as visual information using color or text. In Figure 3, the tracheal intubation tube 200 and the carbon dioxide measuring device 100 are shown in a state connected by arrows, which means that the tracheal intubation tube 200 is coupled to the through hole of the carbon dioxide measuring device 100, and the subject It may mean that exhalation (expiration) of (patient) enters the through hole of the carbon dioxide measuring device 100 through the tube 200 for tracheal intubation.

Figure 4 is a view schematically showing the display of the carbon dioxide measuring device 100 in a situation where the tube 200 for tracheal intubation is properly intubated according to an embodiment of the present application.

Referring to FIG. 4, the tube 200 for tracheal intubation is intubated into the body of the subject (patient), and since the end-tidal carbon dioxide partial pressure in the airway is usually 10 mmHg or more, the carbon dioxide sensor 110 measures the level of carbon dioxide. At this time, when the level of carbon dioxide is measured as 24 mmHg, the determination unit 121 determines that the tracheal intubation tube 200 is intubated into the airway, and the display unit 122 displays it on the display provided in the carbon dioxide measuring device 100 can When the determination result is displayed on the display, it may be displayed as visual information using color or text. In FIG. 4, the tracheal intubation tube 200 and the carbon dioxide measuring device 100 are shown connected by arrows, which means that the tracheal intubation tube 200 is coupled to the through hole of the carbon dioxide measuring device 100, and the subject It may mean that exhalation (expiration) of (patient) enters the through hole of the carbon dioxide measuring device 100 through the tube 200 for tracheal intubation.

According to one embodiment of the present application, the determining unit 121 determines the state of the intubation as an error if the degree of carbon dioxide is less than the first reference value, but if the degree of carbon dioxide exceeds the first reference value, the intubation condition can be considered normal.

The first reference value may be selected by an operator (medical person) or may be a preset value. Determining that the intubation state is erroneous may mean that the tracheal intubation tube 200 is intubated into the esophagus instead of the airway. In addition, when the state of intubation is determined to be normal, it may mean that the tracheal intubation tube 200 is intubated into the airway.

According to one embodiment of the present application, the first reference value may be selected from 6 mmHg to 14 mmHg.

Typically, since the partial pressure of carbon dioxide in the respiratory tract is 10 mmHg or more and the partial pressure in the esophagus is less than 10 mmHg, the first reference value may be selected from 6 mmHg to 14 mmHg. For example, referring to FIG. 3, when the level of carbon dioxide measured by the carbon dioxide sensor 110 is 4 mmHg and the first reference value is 9.2 mmHg, the level of carbon dioxide is equal to or less than the first reference value, so that the tube for tracheal intubation It may be determined that 200 was intubated into the esophagus, and the state of the intubation may be determined to be an error. For example, again referring to FIG. 4 , when the level of carbon dioxide measured by the carbon dioxide sensor 110 is 24 mmHg and the first reference value is 13.9 mmHg, the level of carbon dioxide exceeds the first reference value, so that for tracheal intubation It may be determined that the tube 200 has been intubated into the airway, and it may be determined that the intubation state is normal.

For example, when the tube 200 for tracheal intubation is intubated into the esophagus, the partial pressure of carbon dioxide measured for a predetermined unit time is constant or has a change range within a certain numerical range, and the tube 200 for tracheal intubation is placed in the trachea (airway). The carbon dioxide partial pressure measured for a predetermined unit time at the time of intubation may be highly variable to the extent that the range of change exceeds a predetermined numerical range. Based on this, the determination unit 121 determines the state of the intubation as an error when the degree of carbon dioxide measured for a predetermined unit time is equal to or less than a first reference value and equal to or greater than a second reference value smaller than the first reference value. When the level of carbon dioxide measured for unit time exceeds the first reference value or is less than a second reference value smaller than the first reference value, the state of the intubation may be determined to be normal.

The first reference value and the second reference value may be selected by an operator (medical person) or preset values. Determining that the intubation state is erroneous may mean that the tracheal intubation tube 200 is intubated into the esophagus instead of the airway. In addition, when the state of intubation is determined to be normal, it may mean that the tracheal intubation tube 200 is intubated into the airway.

According to one embodiment of the present application, the display unit 122 may display either a first color display corresponding to the error or a second color display corresponding to the normal.

Referring to FIGS. 3 and 4 , for example, when the intubation state is erroneous, the corresponding first color may be displayed in red, and when the intubation state is normal, the corresponding second color may be displayed in blue. In addition, according to an embodiment of the present application, text may be displayed in addition to the first color and the second color. The text may include information about the level of carbon dioxide and whether or not intubation is required.

FIG. 5 is a diagram schematically illustrating a display of the carbon dioxide measuring device 100 when a tracheal intubation tube is properly intubated according to an embodiment of the present disclosure, but when it is necessary to check the biometric information of a user.

Referring to FIG. 5, a tube 200 for tracheal intubation is intubated into the body of a subject (patient). Normally, when the end-tidal carbon dioxide partial pressure in the airway is 20 mmHg or more, the body is normal, and the end-tidal carbon dioxide partial pressure in the airway If this is greater than or equal to 10 mmHg and less than 20 mmHg, since the person has an abnormality in the body such as cardiac arrest or hypotension, or a person with a normal body, when the carbon dioxide sensor 110 measures the level of carbon dioxide, if the level of carbon dioxide is measured as 14 mmHg, the determination unit 121 determines that the tracheal intubation tube 200 has been intubated into the airway, but there may be an abnormality in the body such as cardiac arrest or low blood pressure, and the display unit 122 displays biometric information on the display provided in the carbon dioxide measuring device 100 You can indicate what to check. When the determination result is displayed on the display, it may be displayed as visual information using color or text. In FIG. 5, the tracheal intubation tube 200 and the carbon dioxide measuring device 100 are shown connected by arrows, which means that the tracheal intubation tube 200 is coupled to the through hole of the carbon dioxide measuring device 100, and the subject It may mean that exhalation (expiration) of (patient) enters the through hole of the carbon dioxide measuring device 100 through the tube 200 for tracheal intubation.

According to an embodiment of the present application, the carbon dioxide measuring device 100 includes a receiving unit (not shown) for receiving biometric information from a user terminal (not shown); And a user terminal (not shown) and an external output device may further include a sending unit (not shown) for sending a message requesting confirmation of the level of carbon dioxide, the state of intubation, and biometric information.

According to one embodiment of the present application, the determination unit 121 determines the state of intubation as an error if the level of carbon dioxide is less than or equal to a first reference value, but if the level of carbon dioxide exceeds the first reference value and is less than or equal to a second reference value, the trachea Based on the biometric information of the target human body for intubation of the intubation tube 200, the state of the intubation is determined as error or normal, but if the level of carbon dioxide exceeds the second reference value, the state of the intubation can be determined as normal there is.

The first reference value and the second reference value may be selected by an operator (medical person) or preset values. If the level of carbon dioxide is less than the first reference value, determining that the intubation state is an error may mean that the tracheal intubation tube 200 is intubated into the esophagus instead of the airway. In addition, if the level of carbon dioxide exceeds the second reference value, determining that the intubation state is normal may mean that the tracheal intubation tube 200 is intubated into the airway. However, when the level of carbon dioxide exceeds the first reference value and is equal to or less than the second reference value, the tracheal intubation tube 200 is intubated into the airway, but there may be an abnormality in the body of the subject (patient). Normally, when the partial pressure of carbon dioxide in the airway is 10 mmHg to 20 mmHg, there may be an abnormality in the body. Therefore, the determination unit 121 determines that the state of intubation is an error if there is an abnormality in the body of the subject (patient) in consideration of the biometric information to be described later, and if there is no abnormality in the body of the subject (patient), the state of intubation is determined. can be judged normal.

According to an embodiment of the present application, the biometric information may be at least one of blood pressure, body temperature, respiration, and heart rate information of the human body.

Typically, when the partial pressure of carbon dioxide in the airway of a subject is 10 mmHg to 20 mmHg, the subject may be normal or may have abnormalities in the body such as blood pressure, body temperature, respiration, and heartbeat.

According to an embodiment of the present disclosure, a user terminal (not shown) is a blood pressure measurement device, a body temperature measurement device, a respiration measurement device, and a heart rate measurement device connected to a network, respectively, through a biometric information measurement menu, and measures blood pressure, body temperature, respiration, and heart rate. It is possible to send a control signal to measure. When the blood pressure measuring device, body temperature measuring device, respiration measuring device, and heart rate measuring device receive a control signal from a user terminal (not shown), they measure blood pressure, body temperature, respiration, and heart rate, respectively, and send them to the user terminal (not shown). Blood pressure information, body temperature information, respiration information, and heart rate information can be transmitted. When the user terminal (not shown) receives the blood pressure information, body temperature information, respiration information, and heartbeat information, the blood pressure information, body temperature information, respiration information, and heartbeat information are sent to a receiver (not shown) of the carbon dioxide measuring device 100. can send

According to an embodiment of the present application, the first reference value may be selected from 6 mmHg to 14 mmHg, and the second reference value may be selected from 16 mmHg to 24 mmHg.

Typically, since the partial pressure of carbon dioxide in the respiratory tract is 10 mmHg or more and the partial pressure in the esophagus is less than 10 mmHg, the first reference value may be selected from 6 mmHg to 14 mmHg. In addition, typically, when the partial pressure of carbon dioxide in the airways of a subject is 10 mmHg to 20 mmHg, the subject may be normal or may have abnormalities in the body such as blood pressure, body temperature, respiration, and heart rate. For example, referring to FIG. 5 , when the level of carbon dioxide measured by the carbon dioxide sensor 110 is 14 mmHg, the first reference value is 9.2 mmHg, and the second reference value is 19 mmHg, the level of carbon dioxide is the first reference value. Since it exceeds the reference value and is less than the second reference value, it is determined that the tracheal intubation tube 200 is intubated into the airway, but in consideration of at least one of blood pressure information, body temperature information, respiration information, and heart rate information included in the biometric information If there is no abnormality, the state of the intubation may be determined to be normal, and if there is an abnormality in the body, the state of the intubation may be determined to be in error. The error in this situation may be determined because the tracheal intubation tube 200 is properly intubated into the airway, but measures for abnormalities in the body take precedence over tracheal intubation.

According to an embodiment of the present application, the display unit 122 displays a first color corresponding to less than the first reference value, displays a second color corresponding to greater than the first reference value and less than or equal to the second reference value, and displays the second reference value. Any one of the third color displays corresponding to the excess may be displayed.

For example, the first color may be red as shown in FIG. 3 , the second color may be yellow as shown in FIG. 5 , and the third color may be blue as shown in FIG. 4 . However, it is not limited thereto. In addition, in the case of the first color and the third color, text including the level of carbon dioxide and whether the intubation was successful may be further included. In addition, in the case of the second color, text including the level of carbon dioxide, biometric information confirmation request, and whether intubation was successful may be further included.
