Description

Technical Field

[0001] The utility model belongs to the field of medical devices, and particularly relates to a visible esophageal intubation tube. Background Art

[0002] A visible esophageal intubation tube is a medical device used for endoscopic examination and treatment of esophageal-related diseases. Its structure generally includes an optical imaging device, catheter material, connecting components, etc. The working principle is mainly based on optical imaging technology. The optical imaging device transmits light through the catheter, enabling doctors to directly observe the internal situation of the esophagus. The characteristics of the catheter material ensure the stability and flexibility of the intubation, enabling doctors to operate accurately.

[0003] The purpose of using a visible esophageal intubation tube is to conduct endoscopic examination, diagnosis, and treatment of esophageal-related diseases. Its usage method includes steps such as guiding the intubation, positioning, endoscopic examination, sampling, treatment, etc. Through this technology, doctors can directly observe the internal situation of the esophagus, accurately diagnose lesions, and conduct corresponding treatments. The significance of this technology lies in improving the diagnostic accuracy and treatment effect of esophageal diseases, reducing the pain of patients and the incidence of complications.

[0004] Currently, the Chinese patent document with the publication number CN 210204683 U discloses a laryngeal mask intubation tube for gastroscopy examination, including a gastroscope catheter. The outer surface of the upper end of the gastroscope catheter is fixedly installed with a drainage cavity pipeline, and one end of the drainage cavity pipeline is fixedly installed with a PC joint. The outer surface of the upper end of the drainage cavity pipeline is provided with ventilation holes, and the outer surface of the lower end of the gastroscope catheter is provided with suction holes. Among them, a catheter inner cavity and an inflation tube socket are arranged inside the gastroscope catheter, and the inflation tube socket is arranged below the catheter inner cavity. An inflation tube penetrates through the inflation tube socket, and one end of the inflation tube is fixedly installed with a single-chamber joint. By fixedly installing a drainage cavity pipeline on the outer surface of the upper end of the gastroscope catheter, the secretions generated at the esophageal orifice of the patient during the gastroscopy process can be drained.

[0005] However, the existing visible esophageal intubation tubes often have the problem that the camera is contaminated by the gastric contents of the patient, resulting in the inability to clearly capture the situation of the patient's stomach; and the catheter inner cavity of the laryngeal mask intubation tube has a fixed size, which needs to be larger than the outer diameter of the colonoscope or gastroscope. During use, the gastric contents of the patient flow out to the outside through the gap between the catheter inner cavity and the colonoscope or gastroscope, contaminating the patient's face and the hospital bed. Summary of the Utility Model

[0006] In response to the above technical problems, the utility model provides a visible esophageal intubation tube. The camera is flushed through a flushing channel to keep the camera clean, thereby clearly capturing the situation of the patient's stomach. It can also suck the esophageal secretions, tissue fluid, or blood through the flushing channel to keep the patient's face and the hospital bed clean.

[0007] The above technical object of the utility model is achieved by the following technical solutions:

[0008] A visible esophageal intubation tube includes an intubation tube body. An airway is formed inside the intubation tube body. The rear end of the airway is inserted into and communicated with a ventilator connector. A camera is installed at the front end of the intubation tube body. A flushing channel is formed inside the intubation tube body, and the outlet of the flushing channel faces the camera directly.

[0009] By adopting the above technical solutions, the intubation tube body integrates multiple functions, including an airway, a ventilator connector, a camera, and a flushing channel, etc., making it multifunctional. Such a design enables the intubation to meet different medical needs, simplifies the medical process, reduces unnecessary instrument replacement, and improves medical efficiency. A camera is installed at the front end of the intubation tube body, which can realize real-time observation and recording of the inside of the esophagus. At the same time, secretions, tissue fluid or blood in the esophagus are aspirated through the flushing hole to keep the patient's face and the hospital bed clean. An airway is formed inside the intubation tube body, and a ventilator connector is installed at the rear end of the airway, which can provide respiratory support to ensure smooth breathing of the patient during intubation, effectively reduce the discomfort caused by the patient's dyspnea, and improve the safety and comfort of the intubation process. The flushing hole is located above the camera to ensure that the camera's field of view will not be blocked during flushing, ensuring the accuracy of the endoscopic examination. At the same time, the installation position of the camera also helps the doctor to accurately locate the intubation position and improves the positioning accuracy of the intubation.

[0010] Furthermore, a large balloon and a small balloon are provided outside the intubation tube body, and both the large balloon and the small balloon surround and wrap the intubation tube body.

[0011] By adopting the above technical solutions, the setting of the large balloon and the small balloon can effectively enhance the stability of the intubation tube in the esophagus. The large balloon can fully fill the esophageal cavity, making the intubation tube more firmly fixed in place, avoiding the situation of the intubation tube sliding or shifting in the esophagus. At the same time, the small balloon can adapt to esophagi of different sizes, making the adaptability of the intubation tube stronger and suitable for the esophagi of patients with different sizes and shapes. The large balloon and the small balloon can form a uniform supporting force in the esophagus, reducing the damage to the esophageal mucosa. Especially during the intubation process and during the indwelling period of the intubation tube, the presence of the large and small balloons can reduce the irritation and compression of the intubation tube on the esophageal mucosa and reduce the risk of esophageal mucosal injury. The large balloon and the small balloon are not likely to cause discomfort when contacting the esophageal mucosa. Their inflation degree can be adjusted according to the specific situation of the patient, making the intubation process more comfortable and reducing the discomfort and anxiety of the patient. The setting of the large balloon and the small balloon improves the fixing degree of the intubation tube in the esophagus and reduces the risk of accidental detachment or displacement. The doctor can precisely control the position and stability of the intubation tube by adjusting the inflation amount of the balloon, improving the safety and controllability of the intubation operation.

[0012] Further setting: An inflation channel is formed inside the intubation tube body. One end of the inflation channel communicates with the large balloon, and the other end of the inflation channel communicates with the small balloon.

[0013] By adopting the above technical solution, by using the inflation channel, the large and small balloons are interconnected to achieve synchronous inflation and deflation. Synchronous inflation and deflation can ensure that the large and small balloons are inflated or deflated simultaneously, maintaining the stability of the intubation in the esophagus. This can prevent the intubation from sliding or shifting in the esophagus, reducing the risk of intubation operation and improving the safety and success rate of treatment.

[0014] Further setting: A pipeline is provided between the large balloon and the small balloon, and the pipeline communicates the large balloon and the small balloon.

[0015] By adopting the above technical solution, by providing a pipeline between the large balloon and the small balloon, synchronous inflation and deflation of the large and small balloons can also be achieved.

[0016] Further setting: The large balloon communicates with the first inflation assembly.

[0017] By adopting the above technical solution, by communicating with the first inflation assembly, the large balloon can be easily connected to an external gas source, and the doctor can control the inflation volume of the large balloon by adjusting the first inflation assembly, thereby accurately adjusting the pressure in the esophagus. This can avoid over-inflation or under-inflation, reducing damage to the esophageal mucosa and discomfort of the patient.

[0018] Further setting: The rear end of the airway is on the same side as the rear end of the intubation tube body, and the front end of the airway is located between the large balloon and the small balloon.

[0019] By adopting the above technical solution, the setting of the airway ventilation pipeline enables the patient to maintain unobstructed breathing while intubated. The ventilation holes are located between the large balloon and the small balloon, ensuring that when the intubation is in the airway ventilation pipeline, inflation of the large and small balloons will not obstruct the patient's breathing, improving the safety and comfort during the intubation process. The setting of the airway ventilation pipeline effectively prevents the risk of airway obstruction and asphyxia caused by inflation of the large and small balloons. Even when the intubation tube body is filled with gas, the airway ventilation holes still allow air to pass freely, ensuring the normal operation of the patient's respiratory function and reducing the incidence of respiratory complications. Maintaining unobstructed breathing during the intubation process helps reduce the patient's anxiety and discomfort, improving the treatment effect. The patient's smooth breathing makes the patient more accepting of the intubation, facilitating subsequent endoscopic examinations and treatment operations by the doctor. The presence of the airway ventilation pipeline improves the safety of the intubation operation. Even in an emergency, the patient can still breathe on their own through the airway ventilation holes, avoiding the risk of asphyxia caused by airway obstruction during the intubation process.

[0020] Further setting: An inner cavity is formed inside the intubation tube body, and an installation tube is arranged in the inner cavity of the tube body. The camera is installed at the front end of the installation tube.

[0021] By adopting the above technical solution, the installation tube can provide additional support and stability to ensure that the camera always maintains the correct position and angle. This helps doctors observe the internal situation of the esophagus, improving the accuracy and reliability of the endoscopic examination. The installation tube can prevent the camera from being interfered or vibrated by the outside world, thus ensuring the stability and clarity of the image. It enables doctors to accurately identify lesions or abnormalities in the esophagus, improving the accuracy of diagnosis.

[0022] Further setting: The camera is connected to a camera wire harness, and the camera wire harness passes through the installation tube and is connected to the output end of the camera.

[0023] By adopting the above technical solution, connecting the camera to the camera wire harness can ensure the reliable transmission of images and data. The wire harness provides a good connection, reducing interference and interruption during data transmission, and ensuring the stability and clarity of the image. The camera wire harness passes through the installation tube and is connected to the output end of the camera, making the installation and adjustment of the camera more convenient.

[0024] Further setting: An inner cavity balloon is provided at the front end of the intubation tube body, and the inner cavity balloon is communicated with a second inflation assembly.

[0025] By adopting the above technical solution, by inflating and deflating, the inner cavity balloon is inflated to seal the colonoscope or gastroscope, so that the patient's reflux material will not pass through the cavity to the respiratory tract or outside the body. When the inner cavity balloon is inflated, it can effectively seal the colonoscope or gastroscope to prevent gastric contents or other liquids from refluxing through the cavity to the respiratory tract or outside the body. It can reduce the risk of food or liquid aspiration during intubation, and reduce the incidence of respiratory tract infections and other complications. By connecting the inner cavity balloon to the second inflation assembly and sealing it by inflation, the safety of the intubation operation can be effectively improved. When the inner cavity balloon is inflated, it can seal the colonoscope or gastroscope to prevent gastric contents or other liquids from entering the intubation environment, keeping the intubation environment clean. This helps to reduce interference during the operation and improve the accuracy and success rate of endoscopic examination and treatment.

[0026] Further setting: The inner cavity balloon is an annular balloon, and the inner cavity balloon tightly seals the inner cavity of the tube body.

[0027] By adopting the above technical solution, the design of the annular balloon can provide better sealing performance. This can effectively prevent food or liquid from refluxing from the esophagus to the inner cavity of the tube body or outside the body, reducing cross-contamination between the inside and outside of the esophagus and improving the safety of the intubation operation. The excellent sealing performance and stability of the annular balloon can reduce the risk of reflux material in the esophagus, thereby reducing the possibility of complications during the intubation operation.

[0028] In summary, the present utility model has the following beneficial effects:

[0029] 1. The camera of the present utility model can realize real-time observation and video recording functions. The flushing channel and the flushing holes not only have a cleaning effect and can clean the camera, but also can aspirate esophageal secretions, tissue fluid or blood, improving the safety and comfort during the intubation process.

[0030] 2. The setting of the large balloon and the small balloon in the present utility model enhances the stability of the intubation in the esophagus and reduces the risk of intubation operation. By controlling the inflation and deflation of the inner cavity balloon, the colonoscope or gastroscope can be sealed, thus preventing food or liquid from flowing back into the respiratory tract or outside the body. Furthermore, the risk of aspiration of food or liquid during the intubation process is reduced, ensuring the safety of the patient.

[0031] 3. The present utility model integrates multiple functions such as an airway, a ventilator connector, a camera, and a flushing channel, making the intubation multifunctional. Furthermore, the medical process is simplified, unnecessary instrument replacement is reduced, and medical efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0042] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0043] Embodiment 1

[0044] As Figures 1-3 shown, an embodiment 1 of a visible esophageal intubation tube includes an intubation tube body 1. An airway 1-1 is formed inside the intubation tube body 1. The rear end of the airway 1-1 is inserted into and communicated with a ventilator connector 2. A camera 3 is installed at the front end of the intubation tube body 1. A flushing channel 1-2 is formed inside the intubation tube body 1. The outlet of the flushing channel 1-2 faces the camera 3 directly.

[0045] A connector is provided at the rear end of the flushing channel 1-2. When the flushing function of the flushing channel 1-2 needs to be realized, the connector is communicated with an external water inlet pipe to realize the flushing function of the camera 3. When the suction function of the flushing channel 1-2 needs to be realized, the connector is connected to a suction instrument such as a syringe, a negative pressure drainage device or a suction pipe to suck the reflux in the esophagus.

[0046] As Figures 4-5 shown, a large balloon 4 and a small balloon 5 are provided outside the intubation tube body 1. The large balloon 4 and the small balloon 5 both surround and wrap the intubation tube body 1. An inflation channel 1-3 is formed inside the intubation tube body 1. One end of the inflation channel 1-3 is communicated with the large balloon 4, and the other end of the inflation channel 1-3 is communicated with the small balloon 5. The large balloon 4 is communicated with a first inflation assembly 6. The rear end of the airway 1-1 is on the same side as the rear end of the intubation tube body 1, and the front end of the airway 1-1 is located between the large balloon 4 and the small balloon 5. The diameter of the large balloon 4 is larger than that of the small balloon 5. By inflating and deflating through the first inflation assembly 6, the large balloon 4 and the small balloon 5 are inflated to seal the esophagus and pharynx of the patient. The first inflation assembly 6 includes an inflation pipeline, a gas source connection joint and a gas source control valve. The air introduced through the gas source connection joint enters the large balloon 4 and the small balloon 5 to inflate the two.

[0047] As Figure 2 , Figure 3 , Figure 7 , Figure 8 shown, an inner cavity 1-4 of the tube is formed inside the intubation tube body 1. A wire tube 7 is arranged inside the inner cavity 1-4 of the tube. The camera 3 is installed at the front end of the wire tube 7. The camera 3 is connected to a camera wire harness 8, and the camera wire harness 8 passes through the wire tube 7 and is connected to a camera output end 9.

[0048] As Figure 9 shown, an inner cavity balloon 10 is installed at the front end of the intubation tube body 1, and the inner cavity balloon 10 is communicated with a second inflation assembly 11. The inner cavity balloon 10 is an annular balloon, the outer ring of the inner cavity balloon 10 is closely attached to the inner cavity 1-4 of the tube body, and the inner ring of the inner cavity balloon 10 is communicated with the inner cavity 1-4 of the tube body.

[0049] The second inflation assembly 11 includes an inflation pipeline, a gas source connection joint and a gas source control valve. The air introduced through the gas source connection joint enters the inner cavity balloon 10 and inflates it, sealing the colonoscope or gastroscope so that the patient's reflux will not pass through the cavity to the respiratory tract or outside the body.

[0050] Embodiment 2

[0051] The difference from Embodiment 1 is that the connection mode between the large balloon 4 and the small balloon 5 is different.

[0052] As Figure 5 shown, a pipeline 5-1 is provided between the large balloon 4 and the small balloon 5, and the pipeline 5-1 communicates the large balloon 4 and the small balloon 5. Through the setting of the pipeline 5-1, a direct connection is achieved between the large balloon 4 and the small balloon 5. This means that medical staff can control the inflation of the large balloon 4 and the small balloon 5 through a single channel, making the inflation process more accurate and convenient. Medical staff can flexibly adjust the inflation volume of the large balloon 4 and the small balloon 5 according to the specific situation and needs of the patient to achieve the best stability and adaptability.

[0053] The intubation tube body 1 is the main part of Embodiment 1, and an airway 1-1 is formed inside. A ventilator connector 2 is installed at the rear end of the airway 1-1 for connecting a ventilator for respiratory support. A camera 3 is installed at the front end of the intubation tube body 1 for real-time observation and video recording. In addition, a flushing channel 1-2 is formed inside the intubation tube body 1, and flushing holes 6 are provided therein for cleaning the secretions, tissue fluid or blood attached to the camera 3, or as suction holes for sucking the secretions, tissue fluid or blood in the esophagus to discharge them and keep the surgical process clean.

[0054] A large balloon 4 and a small balloon 5 are installed outside the intubation tube body 1, and they surround and wrap the intubation tube body 1. These balloons are connected to the inside of the intubation tube body 1 through an inflation channel 1-3. One end of the inflation channel 1-3 is connected to the large balloon 4, and the other end is connected to the small balloon 5. This setting enables the large balloon 4 and the small balloon 5 to communicate with each other and can achieve synchronous inflation and deflation through inflation and deflation. At the same time, the large balloon 4 is connected to the first inflation assembly 6 to adjust the inflation volume of the balloon.

[0055] An inner cavity balloon 10 is installed at the front end of the intubation tube body 1, and an installation tube connecting the camera 3. The camera 3 is connected to the camera output end 9 through the camera wire harness 8 to ensure reliable transmission of images and data. The inner cavity balloon 10 is an annular balloon, the outer ring of which closely adheres to the inner cavity of the tube body 1-4, and the inner ring is connected and communicated with the inner cavity of the tube body 1-4. By inflating and deflating, the inner cavity balloon 10 can seal the colonoscope or gastroscope to prevent the reflux of food or liquid and protect the respiratory tract safety of the patient.

[0056] During the working process, medical staff first select an appropriate size of the intubation tube body 1, and then insert it into the patient's mouth and reach the esophagus through the larynx. During the insertion process, medical staff can observe the intubation position through the camera 3 to ensure accurate insertion. When the intubation is in place, the airway ventilation pipe 11 ensures the smooth breathing of the patient. If the patient needs respiratory support, medical staff can connect the ventilator connector 2 to the rear end of the intubation to provide appropriate respiratory support. When the intubation reaches the esophageal position, medical staff inflate the large balloon 4 and the small balloon 5 through the inflation channel 1-3. This can increase the stability of the intubation in the esophagus and prevent it from sliding or shifting. When it is necessary to prevent the reflux of food or liquid, medical staff inflate the inner cavity balloon 10 through the second inflation component. The annular design of the inner cavity balloon 10 ensures its close fit with the esophagus to prevent food or liquid from entering the respiratory tract. The camera 3 is installed at the front end of the intubation tube body 1 through the installation tube and is connected to the camera output end 9 through the camera wire harness 8. In this way, medical staff can observe the internal situation of the esophagus in real time, record videos or images for subsequent analysis.

[0057] If necessary, medical staff can flush the camera 3 through the flushing channel 1-2 to keep the inside of the esophagus clean and avoid the influence of secretions or blood on the intubation environment. Medical staff adjust the balloon inflation volume, ventilator parameters, etc. at any time according to the patient's condition and needs, and monitor the patient's breathing and esophageal conditions.

[0058] During the operation, it is also possible to aspirate the esophageal secretions, tissue fluid or blood through the flushing channel 1-2. In this way, the aspiration operation can be carried out without interrupting the ventilation process during the operation, and the safety is higher.

[0059] In summary, in this preferred embodiment, by integrating a variety of functional components, such as the camera 3, the flushing channel 1-2, the balloon, etc., and through appropriate connection and adjustment, the observation, cleaning and respiratory support of the esophageal internal environment are realized, the safety and comfort of the intubation process are improved, and at the same time, the patient's respiratory tract is protected from food or liquid.

[0060] The above embodiments are only explanations of the present utility model, and they are not limitations on the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
