Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a digestive endoscope breathing assistance device. Background Art

[0002] Digestive endoscopy is an important method for diagnosing digestive diseases in modern medicine. It directly enters the patient's respiratory and digestive tract through an endoscope to observe and diagnose the disease in an intuitive way. However, in actual operation, this examination method also brings a series of challenges and risks, especially in airway management and patient safety.

[0003] First, when the endoscope enters the aerodigestive tract, it may partially obstruct the airway and affect the patient's normal breathing. This physical obstruction not only increases the patient's discomfort, but may also cause emergency situations such as dyspnea during the examination. At the same time, in order to relieve the patient's pain and anxiety, sedatives are usually used. However, these drugs tend to reduce the tension of the upper airway muscles, making the airway more prone to collapse, further exacerbating the difficulty of airway management.

[0004] Secondly, digestive endoscopy is usually performed in an operating room without anesthesia, which means that the medical team may lack the necessary equipment and support when dealing with sudden airway problems. In addition, the lighting in the operating room is usually dim, so that doctors can better observe the images transmitted by the endoscope. However, this environment increases the difficulty of intuitive assessment and management of the airway, especially in emergency situations, which may delay the treatment time.

[0005] Furthermore, the patient population undergoing digestive endoscopy is diverse, and many of them may have potential health problems, such as esophageal reflux and dysphagia. These problems may induce airway-related complications during the examination, such as aspiration and suffocation, which seriously threaten the patient's life safety. These risks are particularly significant for the elderly, children, and patients with underlying diseases.

[0006] In summary, while digestive endoscopy provides important diagnostic information, it is also accompanied by many challenges in airway management and patient safety. Therefore, developing a digestive endoscopy breathing assistance device that can effectively assist breathing and reduce the risk of airway obstruction and complications is of great significance for improving the safety of the examination and the comfort of the patient.

[0034] A plurality of buffer springs 28 are arranged between the limit plate 1 and the abutment plate 4, and the front and rear ends of the buffer spring 28 are respectively fixedly connected to the adjacent side walls of the limit plate 1 and the abutment plate 4, and the plurality of buffer springs 28 are distributed in a circular array around the through hole 11; the rear side end of the abutment plate 4 is designed in an arc-shaped structure, an abutment pad 8 is arranged on the abutment plate 4, and a rubber sleeve 6 is arranged on the outer wall of the extension tube 5. By arranging the buffer spring 28, the device can absorb and disperse the pressure generated when the endoscope enters the airway to a certain extent, thereby reducing the risk of airway collapse and damage;

[0035] The air guide cannula 7 and the extension tube 17 are provided with a ventilation channel 24, the two ventilation channels 24 are connected at one end adjacent to each other, and the lower end of the lower ventilation channel 24 does not penetrate, the front side end of the air guide cannula 7 is fixedly connected with a charging and discharging connecting pipe 22, the charging and discharging connecting pipe 22 is connected with the ventilation channel 24, and a manual valve 23 is provided on the charging and discharging connecting pipe 22, an annular mounting groove 25 is provided on the side wall of the extension tube 17, a hollow rubber ring 26 is provided in the mounting groove 25, and a connecting pipe 27 is fixedly connected to the inner side wall of the rubber ring 26, and the connecting pipe 27 is connected to the inner side wall of the rubber ring 26. One end of the through tube 27 away from the rubber ring 26 passes through the side wall of the mounting groove 25 and is connected to the ventilation channel 24. The rubber ring 26 is connected to the connecting tube 27. The setting of the ventilation channel 24 and the inflation and deflation connecting tube 22 provides the doctor with an additional means of fixing the extension tube 17 to the trachea, further ensuring that the position between the extension tube 17 and the trachea is fixed when the endoscope slides in the endoscope channel 18, thereby ensuring that the patient's breathing is unobstructed. When deflation is needed, the manual valve 23 can be opened to remove the gas in the rubber ring 26.

[0036] Working principle: When in use, the extension tube 17 and the airway cannula 7 are inserted into the patient's mouth in turn, and the end of the extension tube 17 away from the airway cannula 7 is inserted into the patient's trachea. At the same time, the external B-ultrasound equipment is used to ensure that the lower end of the extension tube 17 is located in the trachea, and the manual valve 23 is opened. The air guide channel 20 and the rubber ring 26 are inflated with a syringe. The outer wall of the expanded rubber ring 26 abuts against the inner wall of the trachea, thereby achieving the fixation of the position between the trachea and the extension tube 17, thereby preventing the extension tube 17 from slipping out of the trachea during the examination. After the position of the extension tube 17 is fixed, the restraint belt 2 is used to put it on the patient's head to fix the position of the device.

When the required size of the extension tube 17 and the airway cannula 7 needs to be adjusted, the knob is turned to drive the adjustment tube 15 to rotate, and the distance between the movable plate 3 and the limiting plate 1 is changed by the cooperation between the adjustment tube 15 and the adjustment screw 14. As the distance between the front end of the airway cannula 7 and the limiting plate 1 is adjusted, the size of the airway cannula 7 and the extension tube 17 inserted into the patient's mouth is adjusted; when performing an endoscopic examination, the ventilator connecting tube 21 is externally connected to the ventilator, and the endoscope is inserted from the endoscope channel 18 to enter the esophagus for examination. The device is designed by combining the limiting plate 1, the restraining belt 2 and the movable plate 3, and the device can be stably fixed on the patient to ensure that the airway will not be overly compressed or obstructed during the digestive endoscopy. At the same time, the setting of the airway cannula 7 and the extension tube 17 provides a direct connection channel for the ventilator, ensuring the patient's breathing safety during the examination. By setting the buffer spring 28, the device can absorb and disperse the pressure generated when the endoscope enters the airway to a certain extent, reducing the risk of airway collapse and damage; at the same time, the setting of the ventilation channel 24 and the charging and discharging gas connection tube 22 provides doctors with additional means of fixing the extension tube 17 and the trachea, further ensuring that the position between the extension tube 17 and the trachea is fixed when the endoscope slides in the endoscope channel 18, thereby ensuring smooth breathing for the patient. The limit design of the endoscope channel 18 in the device ensures the stability and accuracy of the endoscope during the examination process, avoiding image blur or examination interruption caused by airway obstruction or patient movement. At the same time, the setting of the protective soft rubber tube 19 also protects the endoscope from damage and extends its service life.
