Description

Carbon dioxide measuring device connected to tracheal intubation tube, control method and system thereof {DEVICE, METHOD AND SYSTEM CONNECTED TO TUBE FOR ENDOTRACHEAL INTUBATION FOR MEASURING CARBON DIOXIDE}

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

Tracheal intubation is a procedure that secures the airway by inserting a tube into the trachea of a patient who requires airway maintenance or ventilator treatment. By maintaining the airway clearly, ventilation and oxygenation can be carried out efficiently, allowing effective suction and administration of emergency drugs through the airway. It cannot be performed on patients who cannot move their neck, and because a tube is inserted into the respiratory tract, it can cause discomfort and instability. Tracheal intubation is performed when general anesthesia is required or in emergency situations, and is mainly performed when there is cardiac arrest, respiratory failure, severe upper airway obstruction, head and neck injury, severe facial burns, and endotracheal aspiration of stomach contents.

The procedure involves first having the patient lie down, bend the neck forward and tilt the head back, observe the airway using a laryngoscope, and then insert a tracheal intubation tube. Ensure that the tube is positioned appropriately and secure the tracheal intubation tube. To minimize pain during the procedure and to ensure safe tracheal intubation, painkillers, sedatives, or muscle relaxants are used before the procedure. However, in emergency situations or situations where sedatives cannot be used, drugs may not be used. The likelihood of success is over 90%, including cases where multiple attempts are possible, and the procedure time is approximately 5 minutes, but may change depending on the progress of the procedure. During the procedure, the procedure may inevitably change or the scope of the procedure may be added depending on the patient's condition.

During the tracheal intubation procedure, local damage to the lips, gums, tongue, pharynx, vocal cords, airway and teeth, aspiration of stomach contents, esophageal intubation, laryngeal spasm, hypoxia, hemorrhage, myocardial infarction, arrhythmia, pneumothorax, use of sedatives or muscle relaxants Toxicity, cardiac arrest, respiratory failure, etc. may occur, and in such cases, immediate first aid is provided by the medical staff in charge. After tracheal intubation, glottic edema, tracheomalacia, and tracheal stenosis may occur, and if tracheal intubation must be maintained for a long period of time, tracheostomy may be necessary. If the course of the disease worsens during ventilator treatment after tracheal intubation, extubation may be difficult, and in such cases, consultation with the hospital ethics committee may be necessary. Complications that may occur during tracheal intubation include cases where the tube is inserted outside the trachea, the airway is damaged during the intubation process, physical reflexes occur due to stimulation of tracheal intubation, or abnormalities in the function of the intubation occur.

Such tracheal intubation is a difficult surgical procedure (medical procedure) performed in emergency situations, and if it fails, it can pose a threat to the patient's survival and safety. Recently, video laryngoscopes, etc. are used during tracheal intubation procedures, but there are cases where intubation is done through the esophagus. In this case, auscultation is performed, and reintubation is performed after extubation. Therefore, accurate procedures are important during tracheal intubation, but it is also important to quickly recognize when esophageal intubation occurs. For this reason, it must be possible to quickly, objectively, and intuitively confirm whether the tracheal intubation procedure was performed correctly.

However, with conventional techniques, it is difficult to be sure of correct intubation of the airway until auscultation after intubation. In addition, auscultation itself has the disadvantage of involving ambient noise or the practitioner's subjective judgment and being time consuming. In addition, if there is still uncertainty after auscultation, end-tidal carbon dioxide partial pressure measurement is performed, which takes more time.

The measured partial pressure of carbon dioxide is different in the trachea and esophagus. Typically, the partial pressure of carbon dioxide measured in the esophagus is less than 10 mmHg, and the partial pressure of carbon dioxide measured in the airway exceeds 20 mmHg in normal people. If the partial pressure of carbon dioxide in the airway is measured at 10 to 20 mmHg, the tracheal intubation tube is intubated in the airway, and there may be a physical abnormality such as low blood pressure or cardiac arrest, or it may be normal.

By assigning weight priority to the carbon dioxide levels measured by the plurality of carbon dioxide sensors 110, only the carbon dioxide level measured by the carbon dioxide sensor 110 with the highest weight priority is set to the carbon dioxide level, and the remaining carbon dioxide levels are set to the carbon dioxide level. The degree can be deleted.

FIG. 3 is a diagram schematically showing the display of the carbon dioxide measurement device 100 in a situation where the tracheal intubation tube 200 is incorrectly intubated into the body of a subject (patient) according to an embodiment of the present application.

Referring to FIG. 3, a tracheal intubation tube 200 is intubated into the body of a subject (patient). Typically, the end-tidal carbon dioxide partial pressure in the airway is 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 has been intubated into the esophagus, and the display unit 122 can display it on the display provided in the carbon dioxide measuring device 100. there is. When the judgment result is displayed on a 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 connected by an arrow, which means that the tracheal intubation tube 200 is coupled to the through hole of the carbon dioxide measuring device 100, and the subject This may mean that the patient's exhaled breath enters the hole of the carbon dioxide measurement device 100 through the tracheal intubation tube 200.

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

Referring to FIG. 4, a tracheal intubation tube 200 is intubated into the body of a subject (patient). Typically, the end-tidal carbon dioxide partial pressure in the airway is 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 24 mmHg, the determination unit 121 determines that the tracheal intubation tube 200 has been intubated into the airway and the display unit 122 displays the carbon dioxide on the display provided in the carbon dioxide measuring device 100. You can. When the judgment result is displayed on a display, it may be displayed as visual information using color or text. In Figure 4, the tracheal intubation tube 200 and the carbon dioxide measuring device 100 are shown connected by an arrow, which means that the tracheal intubation tube 200 is coupled to the through hole of the carbon dioxide measuring device 100, and the subject This may mean that the patient's exhaled breath enters the hole of the carbon dioxide measurement device 100 through the tracheal intubation tube 200.

According to one embodiment of the present application, the determination unit 121 determines the state of the intubation as an error if the level of carbon dioxide is below the first reference value, but if the level of carbon dioxide exceeds the first reference value, the determination unit 121 determines the state of the intubation as an error. The condition can be judged to be normal.

The first reference value may be selected by the operator (medical professional) or may be a preset value. The fact that the state of intubation is determined to be an error may mean that the tracheal intubation tube 200 is intubated in the esophagus rather than the trachea. Additionally, the fact that the state of intubation is determined to be normal may mean that the tracheal intubation tube 200 has been 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, the partial pressure of carbon dioxide in the airway is 10 mmHg or more, and the partial pressure in the esophagus is less than 10 mmHg, so the first reference value can 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 less than the first reference value, so the tracheal intubation tube (200) may be determined to have been intubated in the esophagus, and the state of intubation may be determined to be an error. For example, referring to FIG. 4 again, 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 it is suitable for tracheal intubation. It may be determined that the tube 200 has been intubated into the airway, and the state of intubation may be determined to be normal.

As an example, when the tracheal intubation tube 200 is intubated into the esophagus, the partial pressure of carbon dioxide measured during a preset unit time is constant or the change range is within a certain value range, and the tracheal intubation tube 200 is in the trachea (airway). The partial pressure of carbon dioxide measured during a preset unit time at the time of intubation may be so variable that the change range is outside a certain numerical range. Based on this, the determination unit 121 determines the state of intubation as an error if the degree of carbon dioxide measured during a preset unit time is less than the first reference value and is more than the second reference value less than the first reference value, but the preset If the level of carbon dioxide measured during unit time exceeds the first reference value or is less than the second reference value less 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 the operator (medical professional) or may be preset values. The fact that the state of intubation is determined to be an error may mean that the tracheal intubation tube 200 is intubated in the esophagus rather than the trachea. Additionally, the fact that the state of intubation is determined to be normal may mean that the tracheal intubation tube 200 has been intubated into the airway.

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

Referring to FIGS. 3 and 4 , for example, when the intubation state is in error, the corresponding first color may be displayed as red, and when the intubation state is normal, the corresponding second color may be displayed as blue. Additionally, 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 intubation is performed.

FIG. 5 is a diagram schematically showing the display of the carbon dioxide measurement device 100 when the tracheal intubation tube is properly intubated but it is necessary to check the patient's biometric information according to an embodiment of the present application.

Referring to FIG. 5, a tracheal intubation tube 200 is intubated into the body of a subject (patient). Typically, the body is normal when the end-tidal carbon dioxide partial pressure in the airway is 20 mmHg or more, and the end-tidal partial pressure of carbon dioxide in the airway is 20 mmHg or more. If it is 10 mmHg or more and less than 20 mmHg, the person has a physical abnormality such as cardiac arrest or low blood pressure, or the body is normal. Therefore, when the carbon dioxide sensor 110 measures the level of carbon dioxide, if the level of carbon dioxide is measured to be 14 mmHg, the judgment unit (121) determines that although the tracheal intubation tube (200) has been intubated into the airway, 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 judgment result is displayed on a display, it may be displayed as visual information using color or text. In Figure 5, the tracheal intubation tube 200 and the carbon dioxide measuring device 100 are shown connected by an arrow, which means that the tracheal intubation tube 200 is coupled to the through hole of the carbon dioxide measuring device 100, and the subject This may mean that the patient's exhaled breath enters the hole of the carbon dioxide measurement device 100 through the tracheal intubation tube 200.

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

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 below the first reference value, but if the level of carbon dioxide exceeds the first reference value and is below the second reference value, the organ The state of the intubation is judged to be error or normal based on the biometric information of the human body subject to intubation of the intubation tube 200. If the level of carbon dioxide exceeds the second reference value, the state of the intubation can be judged to be normal. there is.

The first reference value and the second reference value may be selected by the operator (medical professional) or may be preset values. If the level of carbon dioxide is below the first reference value, the intubation status is judged to be an error, which may mean that the tracheal intubation tube 200 is intubated in the esophagus rather than the trachea. In addition, if the level of carbon dioxide exceeds the second reference value, the condition of the intubation is determined to be normal, which may mean that the tracheal intubation tube 200 has been intubated into the airway. However, if the level of carbon dioxide exceeds the first reference value and is below the second reference value, the tracheal intubation tube 200 is intubated in the airway, but there may be an abnormality in the subject's (patient) body. Typically, when the partial pressure of carbon dioxide in the airway is 10 mmHg to 20 mmHg, there may be something wrong with the body. Therefore, the determination unit 121 considers the biometric information, which will be described later, and determines that the intubation status is an error if there is an abnormality in the subject's (patient's) body, and if there is no abnormality in the subject's (patient's) body, the determination unit 121 determines the intubation status as an error. can be judged to be normal.

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

Typically, when the partial pressure of carbon dioxide in the subject's airway is 10 mmHg to 20 mmHg, the subject may be normal or may have physical abnormalities such as blood pressure, body temperature, breathing, and heart rate.

According to an embodiment of the present application, the user terminal (not shown) is a network-connected blood pressure measurement device, body temperature measurement device, respiration measurement device, and heart rate measurement device, respectively, through the biometric information measurement menu. A control signal can be transmitted to measure . When the blood pressure measurement device, body temperature measurement device, respiration measurement device, and heart rate measurement device receive a control signal from a user terminal (not shown), they measure blood pressure, body temperature, respiration, and heart rate, respectively, and send the information to the user terminal (not shown). Blood pressure information, body temperature information, breathing 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 heart rate information, it transmits the blood pressure information, body temperature information, respiration information, and heart rate information to the receiver (not shown) of the carbon dioxide measurement device 100. It can be sent.

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, the partial pressure of carbon dioxide in the airway is 10 mmHg or more, and the partial pressure in the esophagus is less than 10 mmHg, so the first reference value can be selected from 6 mmHg to 14 mmHg. Additionally, generally, when the partial pressure of carbon dioxide in the subject's airway is 10 mmHg to 20 mmHg, the subject may be normal or may have physical abnormalities such as blood pressure, body temperature, breathing, 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 below the second reference value, it is determined that the tracheal intubation tube 200 has been intubated in the airway, but considering 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 can be judged as normal, and if there is an abnormality in the body, the state of the intubation can be judged as an error. The error in this situation may be determined because although the tracheal intubation tube 200 is properly intubated in the airway, measures for physical abnormalities are given more priority than tracheal intubation.

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

For example, the first color may be red as in FIG. 3, the second color may be yellow as in FIG. 5, and the third color may be blue as in FIG. 4. However, it is not limited to this. Additionally, in the case of the first and third colors, text including the level of carbon dioxide and whether intubation was successful may be further included. Additionally, in the case of the second color, text including the level of carbon dioxide, a request to confirm biometric information, and whether intubation was successful may be further included.
