Description

Tracheal tube monitoring device and human airway environment monitoring and control system

Technical Field

The invention relates to a tracheal tube monitoring device and a human airway internal environment monitoring and control system, belonging to the technical field of human airway monitoring.

Background Art

Endotracheal intubation is a method of inserting a special endotracheal tube into the trachea or bronchus through the oral or nasal cavity and the glottis, which provides the best conditions for airway patency, ventilation and oxygen supply, and airway suction, and is an important measure to rescue patients with respiratory dysfunction. The existing endotracheal tube in clinical practice is a transparent curved tube about 33 cm long, with an airway connector at the end, and a cuff set at the insertion end of the tube, which is used to seal the inner wall of the patient's airway and the space outside the endotracheal tube to ensure that the breathing circuit is leak-proof. The cuff and the indicator balloon are connected through the inflation tube.

The existing endotracheal tubes have relatively simple functions, mainly relying on the cuff to seal the patient's airway, so that the positive pressure cannot escape from the lower respiratory tract, and to seal the upper respiratory tract, so that the material above the glottis cannot enter the trachea. During use, when the cuff is not fully expanded or insufficiently inflated, wrinkles or gaps will be formed against the airway, resulting in the cuff not being able to seal the patient's airway tightly, causing air leakage in the airway, poor ventilation, and secretions above the cuff leaking into the lower respiratory tract along the wrinkles or gaps. When the cuff is over-inflated, the pressure of the cuff on the patient's airway is too high, resulting in impaired perfusion of the airway mucosal capillaries. Long-term compression of the airway mucosa will cause the airway mucosa to fall off and become necrotic, and even form a tracheal fistula.

During the use of endotracheal tubes, excessive sputum and sputum crust formation may cause airway obstruction. Currently, sputum suction during endotracheal intubation is usually performed manually every 2-3 hours. During the interval, sputum accumulates in the trachea, and the airflow flows back and forth during breathing, taking away moisture, causing some sputum to dry and form sputum crusts, which are difficult to suction out under negative pressure. The sputum crusts may even block the lumen of the endotracheal tube, increasing ventilation resistance and airway pressure. At the same time, manual sputum suction also increases the burden on medical staff. Repeated sputum suction operations can damage the tracheal mucosa, causing damage to the cilia of the tracheal mucosa, reducing sputum discharge ability, and increasing the patient's chance of lung infection.

The displacement of the position of the tracheal tube can also cause airway obstruction. The existing tracheal tube cannot reflect its own patency, which is prone to adverse consequences such as poor ventilation or suffocation of the patient due to tracheal tube blockage. The tracheal tube is usually placed for a long time, generally about 3-7 days. If the patient cannot remove the tube, a tracheotomy is required. Tracheotomy is not only expensive and risky, but also prone to incision infection and even death. Even if the tracheotomy is recovered, it is often accompanied by a significant scar on the patient's neck, which not only affects the appearance, but also causes stenosis of the tracheal cavity and brings other risks.

In summary, the existing endotracheal tube has a single function, which is mainly to assist patients in ventilation. It lacks monitoring sensors and monitoring channels, and is unable to monitor and analyze various indicators in the human airway. During mechanical ventilation, the data such as relative humidity, gas concentration, and catheter cuff pressure in the trachea are still fuzzily adjusted based on clinical experience. There is no quantitative standard, and Internet medical equipment cannot be accurately controlled in a timely manner. Ultimately, after the endotracheal tube is removed, the patient will experience multiple complications such as throat pain, hoarseness, tracheal mucosal damage, dry mouth, atelectasis, hypothermic anesthesia, delayed awakening, etc., and it is impossible to provide patients with comfortable and precise medical services.

The features and properties of the present invention are further described in detail below in conjunction with the embodiments.

Embodiment 1 of the endotracheal tube monitoring device of the present invention:

As shown in Figure 1, the endotracheal tube monitoring device includes a monitor 1 and an endotracheal tube 4. One end of the monitor 1 is provided with a standardized endotracheal tube interface 2 for connecting to a mechanical ventilation device. The other end of the monitor 1 is provided with a connecting seat 3 connected to the endotracheal tube interface 2, and the endotracheal tube 4 is connected to the connecting seat 3.

The monitor 1 is provided with a pressure sensor 6, a battery pack 8, a controller 9, an alarm device 10, a wireless transmission device 11, an automatic pressurized air pump 12, and an air pressure chamber 30. The monitor 1 is provided with a display screen 5, a battery power display 13, a power switch 14, and a pressurized air pump control button 27. Among them, the pressure sensor 6 is a micro pressure sensor, the controller 9 is a circuit board with a single chip microcomputer as the core, the controller 9 is connected to the display screen 5, the pressure sensor 6, and the automatic pressurized air pump 12 through a power line and a data line, respectively, and the battery pack 8 is connected to the automatic pressurized air pump 12, the controller 9, and the display screen 5 through a power line and a data line, respectively.

The tracheal tube 4 is used to extend into the human airway. A catheter cuff 17 is provided on the front end of the tracheal tube 4. As shown in FIG. 1 and FIG. 2 , a first inflation channel 16 and a second inflation channel 38 are provided in the wall of the tracheal tube 4. The end of the first inflation channel 16 has a first inflation channel outlet 31 communicating with the inner cavity of the catheter cuff 17. The end of the second inflation channel 38 has a second inflation channel outlet 39 communicating with the inner cavity of the catheter cuff 17. The automatic pressurized air pump 12 is connected to the first inflation channel 16 through the first connecting pipe 28. The pressurized air pump control button 27 is used to control the automatic pressurized air pump 12 to work and automatically inflate the catheter cuff 17 through the first inflation channel 16. At the same time, one end of the second connecting tube 36 is connected to the second inflation channel 38, and the other end is connected to the air pressure chamber 30 in the monitor 1. The air pressure chamber 30 is connected to the pressure sensor 6. Therefore, when the automatic pressurizing air pump 12 is inflating, the gas in the catheter cuff 17 enters the air pressure chamber 30 through the second inflation channel 38 and the second connecting tube 36, so that the pressure sensor 6 can detect and convert the gas pressure in the catheter cuff 17 and display the gas pressure value on the display screen 5. At the same time, the pressure sensor 6 transmits the detection information to the controller 9. When the gas pressure in the catheter cuff 17 reaches the value within the safety range, the controller 9 commands the automatic pressurizing air pump 12 to stop inflating. When the gas pressure in the catheter cuff 17 is insufficient, the controller 9 commands the automatic pressurizing air pump 12 to continue inflating. The automatic pressurizing air pump 12 also has a timing self-deflation function.

In addition, the tracheal tube 4 is connected to a third connecting tube 37 connected to the first inflation channel 16, and an outer air bag 29 is provided at the end of the third connecting tube 37. When in use, the outer air bag 29 is located outside the body, and the inflation condition of the catheter cuff 17 can also be judged by observing the bulging degree of the outer air bag 29. The tracheal tube 4 and the catheter cuff 17 in the present invention are provided with a monitor for monitoring the environmental data in the human airway. The monitor is connected to the controller 9 via a data line so that the controller 9 can receive the data monitored by the monitor.

The temperature sensor 41 is a miniature temperature probe sensor, which is implanted on the surface of the catheter cuff 17, and its data line is connected to the sensor interface 7 of the controller 9 through the line channel 15. The catheter cuff 17 is in direct contact with the inner wall of the airway, and the temperature sensor 41 is implanted on the surface of the catheter cuff 17, which is convenient for detecting the temperature of the inner wall of the airway and grasping the real temperature of the airway during the patient's surgery in real time. The electrochemical gas sensor 19 is a miniature flexible electrochemical gas sensor, which is implanted in the front end lumen of the tracheal tube 4, and its data line is connected to the sensor interface 7 of the controller 9 through the line channel 15, which is convenient for detecting the gas concentration (such as oxygen and carbon dioxide) in the patient's trachea, and indirectly evaluating the appropriate state of the airway, including ventilation efficiency and possible humidity changes. Based on the gas concentration data, the airway condition can be judged more accurately, so that when abnormal concentrations are detected, an alarm can be issued in a timely and intelligent manner, guiding medical staff to promptly discover and respond to potential ventilation or airway humidity problems, and further optimize the patient's respiratory management and nursing quality.

The monitor also includes a camera, which includes a first camera 26 built into the catheter cuff 17. The first camera 26 is a micro high-definition 3D camera, and its data line is connected to the controller 9 through the line channel 15, which is used to observe the compression of the tracheal mucosa by the catheter cuff 17 and the subglottic mucus secretion above the catheter cuff 17, so as to conveniently and intuitively grasp the damage of the tracheal mucosa and the secretion of subglottic mucus. The camera also includes a second camera 23 arranged at the front end of the tracheal tube 4. The second camera 23 is also a micro high-definition 3D camera, and its data line is connected to the controller 9 through the line channel 15. The front end of the tracheal tube 4 is embedded with a red light 40, and its data line is connected to the controller 9 through the line channel 15, so as to illuminate the patient's airway at the front end of the tracheal tube 4. With the second camera 23, the sputum secretion and blockage in the tracheal cavity can be observed, so as to conveniently and intuitively grasp the sputum accumulation.

The suction tube is provided with a suction interface 35. When in use, the suction interface 35 is located outside the human body. The sputum accumulated in the front end of the tracheal tube 4 and the subglottic airway can be sucked out through the suction interface 35 to avoid the formation of sputum scab.

It should be noted that the first inflation channel 16, the second inflation channel 38, the injection channel 32, the suction channel 33 and the line channel 15 are all capillary channels, and these five channels are all located in the wall of the tracheal tube 4, and the first connecting tube 28, the second connecting tube 36, the third connecting tube 37, the injection tube, and the suction tube are all capillary connecting tubes to avoid affecting the normal insertion of the tracheal tube 4 into the human airway and avoiding affecting normal mechanical ventilation.

Improve the quality and intelligence level of medical services, and promote the intelligent development of medical equipment, such as anesthesia intubation robots, medical intelligent nebulizers, image recognition electric suction devices, etc. The technical principle is based on the special position of the endotracheal tube inserted in the human trachea. The endotracheal tube is used as a carrier, a capillary channel is set in the tube wall, and micro sensors and visualization tools are implanted in the cavity, head end, cuff, and cuff surface to collect various monitoring data in the human trachea. The data are sent to the control device through wireless transmission technology, where the monitoring data is monitored and intelligently analyzed in real time. With the control device as the center, the Internet 5G technology is used to perform closed-loop intelligent control and management of related interconnected medical equipment.

The intelligent monitoring and control system of the human tracheal environment with a tracheal tube monitoring carrier of the present invention can be used for all patients who apply tracheal intubation, and can be used in other medical departments, such as ICU, emergency department and other departments that need intubation rescue. The existing tracheal tube is used for mechanical ventilation because the data such as tracheal temperature, relative humidity, oxygen concentration, and catheter cuff pressure are fuzzily adjusted by clinical experience, there is no quantitative standard, and it cannot be regulated in time, which eventually leads to multiple complications such as throat pain, hoarseness, tracheal mucosal damage, dry mouth, atelectasis, hypothermic anesthesia, delayed awakening, etc. after the patient pulls out the tracheal tube. The intelligent monitoring and control system of the human tracheal environment cross-developed by the present invention uses sensors, integrated chips, 5G transmission, intelligent control and other technologies and medicine to perform real-time monitoring of all monitoring data in the trachea, and intelligently analyzes the monitoring data, accurately controls the interconnected medical equipment within a controllable safety range, avoids the above complications, and provides comfortable and accurate medical services for patients.

At present, there is still a blank in the monitoring of the human tracheal environment. All data still rely on clinical experience, and fuzzy treatment is performed using existing medical equipment. For example, when patients use endotracheal intubation for mechanical ventilation, a large amount of water in the human trachea will be taken away, causing an extreme decrease in relative humidity, dry mouth, atelectasis and other phenomena. Clinicians use artificial noses, nebulizers, and heated humidifiers for prevention based on clinical experience. Due to the lack of data quantification, insufficient or excessive atomization often occurs, making it difficult to achieve precise treatment. The present invention accurately regulates future medical intelligent equipment based on relevant data monitored by sensors in the human trachea, ensures that patients are in the best state, forms the Internet of Everything, and will surely promote the intelligent development of medical equipment.
