Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a visual double-balloon endotracheal tube. Background Art

[0002] An artificial airway is a crucial measure for mechanical ventilation and the treatment of critically ill patients. An endotracheal tube is a medical device that inserts a flexible plastic or rubber tube into the patient's trachea to maintain airway patency. An endotracheal tube typically consists of an overtube and a stylet. The overtube is inserted into the patient's trachea, while the stylet is inserted inside the overtube to maintain ventilation. The overtube is typically held in place by a cuff, maintaining tight contact with the patient's trachea. Improper cuff pressure management can severely impact patient outcomes. Overinflation of the cuff and excessive pressure can lead to prolonged airway compression, ischemia and necrosis of the airway mucosa, and the proliferation of granulation tissue. Underinflation can cause upper respiratory secretions to leak around the cuff, leading to air leaks during mechanical ventilation. This can lead to complications such as hypoventilation and ventilator-associated pneumonia, prolonging hospital stays, increasing medical costs, and mortality, severely impacting patient outcomes. At the same time, the actual pressure threshold of the patient's trachea varies from person to person. Simply monitoring the air bag pressure is difficult to truly reflect the compression condition of the patient's trachea and the actual shape of the outer tube, and thus it is impossible to make an effective and timely response.

[0037] like Figure 1 As shown, the present application provides a visual double-balloon endotracheal tube, comprising:

[0038] An endotracheal tube outer tube 1, wherein one end of the endotracheal tube outer tube 1 is a distal end and the other end is a proximal end, and the outer surface of the endotracheal tube outer tube 1 is coated with a radiation scattering coating, and the radiation scattering coating is used to detect the reflection of radiation from the outer surface of the endotracheal tube outer tube 1 by a radiation visualization device;

The first air pressure indicating balloon 4a and the second air pressure indicating balloon 4b are respectively connected to the first inflation valve 5a and the second inflation valve 5b; the inflation valve 5 is used to inflate the airbag 2, and the air pressure indicating balloon 4 can indicate the air pressure inside the airbag 2.

[0042] The present application achieves visualization by coating the outer surface of the endotracheal tube outer sleeve 1 with a radiation scattering coating, so that the morphological contour of the endotracheal tube can be observed when the endotracheal tube is placed in the human body, which facilitates monitoring and alarm, and avoids situations that are harmful to the human body such as tracheal leakage or flatulence; at the same time, the airbag inflation can fix the distal end of the endotracheal tube outer sleeve, and the double airbag setting can prevent the symptoms of tracheal mucosal ischemia, erosion, necrosis, etc. caused by long-term pressure on the inner wall of the trachea due to single airbag fixation.

[0043] In a specific embodiment, the device further comprises:

[0044] An excitation light source unit, the excitation light source unit is used to generate a light source of a specific wavelength or frequency to excite the radiation scattering coating on the outer surface of the endotracheal tube outer sleeve 1 to generate a reflection signal;

[0045] A coating reaction capture unit, the coating reaction capture unit is used to capture the reflected signal of the radiation from the outer surface of the endotracheal tube outer tube 1;

[0046] A data processing unit, which is responsible for processing and analyzing the captured reflection signals to obtain clear imaging results;

[0047] A display unit is used to display the processed imaging results on a screen.

[0048] Depending on the imaging technique, the excitation light source can be visible light, ultraviolet light, infrared light, fluorescence, or X-rays, and the corresponding detector, camera, or sensor is used to capture the reflected signal. During the data processing process, the imaging results can be generated and stored through algorithms such as clutter filtering, signal enhancement, and image reconstruction.

[0050] The device in the present application further includes: a WiFi module, which is used to transmit the imaging results to the display unit in real time.

[0051] In another specific embodiment, the device further comprises:

[0053] In a specific embodiment, the device further comprises: a monitoring unit, the monitoring unit being configured to monitor the outer surface morphology of the endotracheal tube overtube 1 according to a historical imaging result classification table and a corresponding processing log, and the monitoring unit being configured to generate an alarm if the imaging result of the outer surface of the endotracheal tube overtube 1 is classified into a category that requires monitoring or cannot be classified. Generally speaking, the minimum threshold for airway pressure alarm is 20 cmH2O or the maximum threshold is 30 cmH2O, but in practice, it has been found that the thickness of the patient's trachea varies from person to person, and the airway pressure tolerance range is not exactly the same. By recording the imaging results of the endotracheal tube overtube under normal conditions as historical imaging results when the endotracheal tube is placed, and accumulating and learning the corresponding processing logs of the imaging results of the endotracheal tube overtube under different conditions, data collection, statistics, and improvement can be performed to achieve the purpose of matching the individual patient's trachea needs, and corresponding treatment measures can be found according to the classification table of the imaging results. On this basis, airway pressure thresholds can be set to suit individual patients. If the pressure falls below the minimum threshold or exceeds the maximum threshold, an alarm signal in the form of sound or light will be issued to alert medical staff to take timely action. The alarm device usually includes components such as a speaker, indicator light, and buzzer.

[0054] In a specific embodiment, if Figure 1 As shown, the tail of the air pressure indicator balloon 4 bifurcates into two branches: one branch is an inflation valve tube with an inflation valve 5 at its mouth, and the other branch is an airbag pressure monitor. The airbag pressure monitor has a scale indicating pressure on its wall. Inside the tube is a spring. The end of the spring, near the inflation valve tube, is connected to a circular rubber valve. The diameter of the rubber valve matches the inner diameter of the airbag pressure monitor. When the airbag 2 is inflated, the gas pressure compresses the spring through the rubber valve. The scale at the edge of the rubber valve indicates the gas pressure within the airbag 2, allowing for constant monitoring and timely adjustment of the pressure within the airbag 2.

[0055] However, the current air pressure control of the airbag 2 mainly relies on syringe inflation, and the inflation volume is difficult to control. It is often difficult to accurately control the airbag pressure due to manual adjustment. In another specific embodiment, it also includes: an airbag pressure monitor, the airbag pressure monitor 3 includes a first airbag pressure monitor 13a and a second airbag pressure monitor 13b, the first airbag pressure monitor 13a and the second airbag pressure monitor 13b respectively including an inflation pipe and a deflation pipe, the inflation valve 5 is connected to the inflation pipe and the deflation pipe of the airbag pressure monitor, respectively, the first inflation valve 5a and the second inflation valve 5b are connected to the first airbag pressure monitor 13a and the second airbag pressure monitor 13b respectively, and the airbag pressure monitor can monitor the air pressure in the airbag 2, and the first airbag pressure monitor 13a and the second airbag pressure monitor 13b are used to monitor the air pressure in the first airbag 2a and the second airbag 2b respectively. The airbag pressure monitor can control the inflation pressure in the airbag 2 and control the alternating inflation and deflation times of the first airbag 2a and the second airbag 2b respectively.

[0056] In a specific embodiment, the airbag pressure monitor includes a data transmission module, a processor, and a user interface for transmitting and displaying airbag pressure data.

[0057] In a specific embodiment, the air pressure of the airbag 2 is feedback-regulated through the inflation valve 5 according to the airbag pressure data obtained by the airbag pressure monitor.
