Description

Technical Field

[0001] This invention relates to the field of medical catheters, and in particular to an ultrasound-guided transesophageal bronchial intubation kit. Background Technology

[0002] Currently, endotracheal intubation is widely used in clinical practice for one-lung ventilation, lung surgery, and airway management in critically ill patients. Meanwhile, the ultra-thin gastroscope, also known as a transnasal gastroscope or pediatric gastroscope, is characterized by its slender design and flexible operation, making it suitable for guiding difficult endotracheal intubation. Furthermore, ultra-thin gastroscopy-guided endotracheal intubation has the following advantages: 1. Convenience and speed: The ultra-thin gastroscope is a routinely used endoscope in the endoscopy room, and endoscopists are all familiar with its operation. Especially in emergency situations, using an ultra-thin gastroscope to assist in endotracheal intubation can shorten intubation time and improve the success rate. 2. No requirements for patient position: This method allows for selection of patient position according to surgical needs. Patients can undergo endotracheal intubation in any position, such as lateral, prone, or supine, shortening preparation time and avoiding falls from the bed.

[0003] Regarding the aforementioned technologies, existing methods for assembling bronchial intubation kits mostly rely on the internal and external threads on the tubes or connectors for splicing and fixing. This assembly method adds extra steps for medical staff, requiring them to spend more time and effort on the assembly, and is particularly cumbersome in emergency clinical scenarios, resulting in a significant reduction in overall work efficiency and causing many inconveniences for users. Summary of the Invention

[0004] 1. Technical problems to be solved The purpose of this application is to provide an ultrasound-guided transesophageal bronchial intubation kit to solve the problem of low efficiency caused by using threaded connections to assemble the various bronchial intubation kits.

[0005] This application provides an ultrasound-guided transesophageal bronchial intubation kit, which adopts the following technical solution: a main tube, a quick-connect mechanism, and segmented tubes. The quick-connect mechanism includes connecting ports that are sleeved on both ends of the main tube and the segmented tubes. An elastic ring is fixedly connected inside the connecting port. Two locking blocks are fixedly connected to the surface of the elastic ring. Several circular grooves are formed on the inner wall surface of the main tube and the inner wall surface of the segmented tubes. The locking blocks are inserted into the circular grooves. The surface of the locking blocks is provided with an inclined surface. A rough layer is fixedly connected to the surface of the locking blocks. A sealing gasket is provided on the inner wall surface of the connecting port. Two of the connecting tubes are fixedly connected to a occlusion balloon at one end, and the two connecting tubes are oriented in opposite directions. One of the connecting tubes is fixedly connected to a tube head at one end, and the other connecting tube is fixedly connected to a dual-port universal connector at one end. By adopting the above technical solution and setting up a quick-assembly mechanism, during assembly, the ends of the main pipe and the segmented pipe can be aligned with the connecting pipe opening. Subsequently, the connecting pipe opening is pushed so that the inclined surface of the locking block slides into the circular groove. Then, the elastic force of the elastic ring will cause the locking block to be tightly embedded in the circular groove, and the rough layer increases the friction between the locking block and the circular groove to prevent loosening. At the same time, the sealing gasket on the inner wall of the connecting pipe opening is tightly attached to the inner wall surface of the main pipe and the segmented pipe to achieve a seal. During disassembly, the main pipe and the segmented pipe are pulled in the opposite direction, and the locking block will squeeze the elastic ring to deform, thus detaching from the circular groove. This structural design replaces the traditional threaded connection, eliminates the tedious steps of rotation and alignment, and achieves the goal of enabling medical staff to quickly complete the assembly, greatly reducing operation time. It can improve efficiency, especially in emergency rescue scenarios. The tight fit between the locking block and the circular groove and the design of the sealing gasket achieve the effect of ensuring connection stability and effectively preventing leakage. By incorporating an occlusion balloon, a double occlusion effect can be achieved after intubation. When in use, the inflated balloon fits tightly against the airway wall from different directions, effectively preventing gastric secretions, blood, and other substances from entering the main tube and segment tubes. The tube tip ensures that the high-definition camera maintains a stable observation angle of the airway structure during intubation and operation, avoiding shaky or shifted views due to loose connections. This allows medical staff to clearly and continuously monitor the airway condition. The dual-port universal connector enhances the kit's versatility and expandability, allowing medical staff to simultaneously insert multiple external devices into the dual-port universal connector for subsequent operations.

[0006] Preferably, a suction tube is fixedly connected to the surface of the main tube, a suction head is fixedly connected to one end of the suction tube, a concave annular groove is formed on the surface of the suction head, an elastic clamping ring is sleeved inside the concave annular groove, a first fixing strip is fixedly connected to the surface of the elastic clamping ring, a first sealing cover is fixedly connected to the side of the first fixing strip, and a first handle plate is fixedly connected to the surface of the first sealing cover. By adopting the above technical solution, and by setting up a suction tube, suction head, concave annular groove, elastic clamping ring, first fixing strip, first sealing cap, and first handle plate, when suctioning is needed, the first sealing cap can be pulled by the first handle plate to detach it from the suction tube port. Subsequently, the elastic clamping ring deforms in the concave annular groove to release the seal. After suctioning is completed, the first sealing cap can be pulled back to its original position, and the elastic clamping ring will spring back, making the sealing cap tightly fit the port. This structural design achieves the purpose of facilitating medical staff to clear the patient's airway secretions in a timely manner, avoiding secretion blockage that affects ventilation, while reducing the chance of external contaminants entering the suction tube and reducing the risk of infection.

[0007] Preferably, a balloon tube is fixedly connected to the surface of the main tube, and a bronchial balloon indicator balloon is fixedly connected to one end of the balloon tube, and the balloon tube is connected to the occlusion balloon; By adopting the above technical solution, and by setting up a balloon tube and a bronchial balloon indicator balloon, the bronchial balloon indicator balloon can expand simultaneously when the occlusion balloon is inflated. Subsequently, medical staff can judge the inflation status of the occlusion balloon by the degree of expansion of the indicator balloon, thereby accurately controlling the occlusion force and achieving the occlusion of a specific airway.

[0008] Preferably, a camera flushing tube is fixedly connected to the surface of the main body, one end of the camera flushing tube is fixedly connected to a camera flushing connector, a second fixing strip is fixedly connected to the surface of the camera flushing connector, a second sealing cover is fixedly connected to the side of the second fixing strip, and a second handle plate is fixedly connected to the surface of the second sealing cover. By adopting the above technical solution, and by setting up a camera flushing tube, a camera flushing connector, a second fixing strip, a second sealing cover, a second handle plate, a high-definition camera, and a round hole, when the stomach needs to be cleaned, the second sealing cover can be opened, and flushing fluid can be injected into the camera flushing tube through the camera flushing connector. Subsequently, the flushing fluid is flushed into the area of ​​the patient's stomach to be cleaned through the round hole. After flushing is completed, the second sealing cover is closed to prevent contaminants from entering. According to the structural design, the internal condition of the airway can be clearly displayed. Combined with the quick-operation flushing structure, it ensures a clear field of vision during surgery, which is convenient for medical staff to accurately locate and operate.

[0009] Preferably, a data cable is provided on the surface of the main body, and one end of the data cable is provided with a camera-specific connector; By adopting the above technical solution and setting up a dedicated connector between the data cable and the camera, the purpose of external power supply or data display and transmission for the high-definition camera is achieved.

[0010] Preferably, the dual-port universal connector has two sealing plugs internally engaged, and two semi-circular blocks are fixedly connected to the surface of the sealing plugs; By adopting the above technical solution and setting a sealing plug, the purpose of sealing the inside of the dual-port universal connector is achieved. By setting a semi-circular block, the purpose of making it easy to press and remove the sealing plug is achieved.

[0011] Preferably, a high-definition camera is fixedly installed inside the tube end, and several round holes are opened inside the tube end; By adopting the above technical solution and setting up a high-definition camera, the condition of the stomach can be displayed, and by setting up a round hole, water can be drained from the parts of the stomach that need to be rinsed.

[0012] Preferably, the surface of the main body is provided with a scale.

[0013] 2. Beneficial effects In summary, this application includes at least one of the following beneficial technical effects: 1. This invention provides an ultrasound-guided transesophageal endotracheal intubation kit. By incorporating a quick-assembly mechanism, the ends of the main tube and segmented tubes are aligned with the connecting port during assembly. The connecting port is then pushed, causing the inclined surface of the locking block to slide into the circular groove. The elastic force of the elastic ring then tightly engages the locking block within the groove. The roughened layer increases friction between the locking block and the groove, preventing loosening. Simultaneously, the sealing gasket on the inner wall of the connecting port adheres tightly to the inner surfaces of the main tube and segmented tubes, achieving a seal. During disassembly, pulling the main tube and segmented tubes in the opposite direction causes the locking block to deform by compressing the elastic ring, allowing it to detach from the groove. This structural design replaces traditional threaded connections, eliminating the tedious steps of rotational alignment and enabling medical personnel to quickly complete assembly, significantly reducing operation time. This is particularly beneficial in emergency rescue scenarios. The tight fit between the locking block and the groove, along with the sealing gasket design, ensures both connection stability and effective leakage prevention.

[0014] 2. This invention provides an ultrasound-guided transesophageal endotracheal intubation kit. By incorporating a occlusion balloon, it achieves a double occlusion effect after intubation. During use, when the occlusion balloon is inflated, it fits tightly against the airway wall from different directions, effectively preventing gastric secretions, blood, etc., from entering the main tube and segment tubes. The tube tip ensures that the high-definition camera maintains a stable observation angle of the internal airway structure during intubation and operation, avoiding shaky or shifted views due to loose connections. This allows medical personnel to clearly and continuously monitor the airway condition. The dual-port universal connector enhances the kit's versatility and expandability, allowing medical personnel to simultaneously insert multiple external devices into the dual-port universal connector for subsequent operations.

[0017] The following is in conjunction with the appendix Figure 1 - Appendix Figure 10 This application will be described in further detail below.

[0018] Example 1: A kit for endoscopic ultrasound-guided transesophageal endotracheal intubation, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes a main body 1, a quick-installation mechanism 2, and a segmented pipe 4. The quick-installation mechanism 2 includes connecting pipe ports 201 that are sleeved on both ends of the main body 1 and the segmented pipe 4. An elastic ring plate 202 is fixedly connected inside the connecting pipe port 201. Two locking blocks 205 are fixedly connected to the surface of the elastic ring plate 202. Several circular grooves 203 are opened on the inner wall surface of the main body 1 and the inner wall surface of the segmented pipe 4. The locking blocks 205 are inserted into the inside of the circular grooves 203. An inclined surface 206 is provided on the surface of the locking blocks 205. A rough layer 207 is fixedly connected to the surface of the locking blocks 205. A sealing gasket 204 is provided on the inner wall surface of the connecting pipe port 201. Two of the connecting ports 201 are fixedly connected to one end of a sealing balloon 3, and the two connecting ports 201 are oriented relative to each other. One end of one connecting port 201 is fixedly connected to a tube head 5, and the other end of the connecting port 201 is fixedly connected to a double-port universal connector 6. By setting up a quick-assembly mechanism 2, during assembly, the ends of the main body 1 and the segmented tube 4 can be aligned with the connecting ports 201. Subsequently, pushing the connecting ports 201 causes the inclined surface 206 of the locking block 205 to slide into the circular groove 203. Then, the elastic force of the elastic ring plate 202 will cause the locking block 205 to be tightly embedded in the circular groove 203, and the rough layer 207 increases the friction between the locking block 205 and the circular groove 203. Force is applied to prevent loosening. At the same time, the sealing gasket 204 on the inner wall of the connecting pipe 201 is tightly attached to the inner wall surface of the main pipe 1 and the segmented pipe 4 to achieve a seal. When disassembling, the main pipe 1 and the segmented pipe 4 are pulled in the opposite direction. Subsequently, the locking block 205 will squeeze the elastic ring 202 to deform, and then it can be separated from the circular groove 203. This structural design replaces the traditional threaded connection, saves the tedious steps of rotation and alignment, and achieves the purpose of enabling medical staff to quickly complete the assembly, greatly reducing the operation time. It can improve efficiency, especially in emergency rescue scenarios. The tight fit between the locking block 205 and the circular groove 203 and the design of the sealing gasket 204 achieve the effect of ensuring connection stability and effectively preventing leakage. By setting the occlusion balloon 3, a double occlusion effect can be achieved by inflation after the tube is in place. When in use, when the occlusion balloon 3 is inflated, it can fit tightly against the inner wall of the airway from different directions, effectively preventing secretions and blood from the patient's stomach from entering the main tube 1 and the segment tube 4. By setting the tube head end 5, it can be ensured that the high-definition camera 26 can maintain a stable observation angle of the internal structure of the airway during intubation and operation, avoiding the shaking or deviation of the field of view caused by loose connection, allowing medical staff to clearly and continuously grasp the airway condition. By setting the dual-port universal connector 6, the universality and expandability of the kit are enhanced. When in use, medical staff can insert multiple external devices into the dual-port universal connector 6 at the same time for subsequent operations.

[0019] Please see Figure 5 and Figure 6A suction tube 7 is fixedly connected to the surface of the main body 1. A suction head 12 is fixedly connected to one end of the suction tube 7. A concave annular groove 13 is formed on the surface of the suction head 12. An elastic clamping ring 14 is fitted inside the concave annular groove 13. A first fixing strip 15 is fixedly connected to the surface of the elastic clamping ring 14. A first sealing cover 16 is fixedly connected to the side of the first fixing strip 15. A first handle plate 17 is fixedly connected to the surface of the first sealing cover 16. By setting up the suction tube 7, suction head 12, concave annular groove 13, elastic clamping ring 14, first fixing strip 15, first sealing cover 16 and first handle plate 17, when suctioning is needed, the first sealing cover 16 can be pulled by the first handle plate 17 to disengage it from the end of the suction tube 7. Subsequently, the elastic clamping ring 14 deforms in the concave annular groove 13 to release the seal, and the suctioning is completed. After completion, pulling the first sealing cap 16 resets the pressure, and the elastic clamp 14 springs back, making the sealing cap tightly fit the port. This structural design facilitates timely clearing of airway secretions by medical staff, preventing secretions from blocking ventilation and reducing the chance of external contaminants entering the suction tube 7, thus lowering the risk of infection. A balloon tube 8 is fixedly connected to the surface of the main tube 1, and a bronchial balloon indicator 18 is fixedly connected to one end of the balloon tube 8. The balloon tube 8 is connected to the occlusion balloon 3. By setting the balloon tube 8 and the bronchial balloon indicator 18, when the occlusion balloon 3 is inflated, the bronchial balloon indicator 18 expands accordingly. Subsequently, medical staff can judge the inflation status of the occlusion balloon 3 by the degree of expansion of the indicator 18, thereby accurately controlling the occlusion force and achieving the occlusion of a specific airway.

[0020] Please see Figure 7 and Figure 8 A camera flushing tube 9 is fixedly connected to the surface of the main body 1. One end of the camera flushing tube 9 is fixedly connected to a camera flushing connector 19. A second fixing strip 20 is fixedly connected to the surface of the camera flushing connector 19. A second sealing cover 21 is fixedly connected to the side of the second fixing strip 20. A second handle plate 22 is fixedly connected to the surface of the second sealing cover 21. By setting up the camera flushing tube 9, camera flushing connector 19, second fixing strip 20, second sealing cover 21, second handle plate 22, high-definition camera 26 and round hole 27, when the stomach needs to be cleaned, the second sealing cover 21 can be opened and the camera flushing connector 19 can be used to flush the stomach. Fluid is injected into the camera flushing tube 9, and then flushed into the patient's stomach to be cleaned through the round hole 27. After flushing, the second sealing cap 21 is closed to prevent contaminants from entering. According to the structural design, the internal condition of the airway can be clearly displayed. With the quick-operation flushing structure, the field of vision during the operation is clear, which is convenient for medical staff to accurately locate and operate. The surface of the main body 1 is provided with a data cable 10. One end of the data cable 10 is provided with a camera-specific connector 23. By setting the data cable 10 and the camera-specific connector 23, the high-definition camera 26 can be powered externally or display and transmit data.

[0021] Please see Figure 1 , Figure 9 and Figure 10 The dual-port universal connector 6 has two sealing plugs 24 inside, and two semi-circular blocks 25 are fixedly connected to the surface of the sealing plugs 24. By setting the sealing plugs 24, the internal structure of the dual-port universal connector 6 is sealed. By setting the semi-circular blocks 25, the sealing plugs 24 can be easily removed. A high-definition camera 26 is fixedly installed inside the tube end 5. Several round holes 27 are opened inside the tube end 5. By setting the high-definition camera 26, the condition of the stomach can be displayed. By setting the round holes 27, the water volume of the stomach that needs to be flushed can be drained. The surface of the main tube body 1 is provided with a scale 11. By setting the scale 11, the medical staff can easily observe the tube, and the medical staff can accurately control the insertion depth to avoid it being too deep or too shallow, thus ensuring the safety of operation.

[0022] The implementation principle of this application embodiment is as follows: First, the kit is assembled and prepared. According to the length of the patient's airway, the appropriate main tube 1 and segment tube 4 are selected and quickly connected through the quick-connect mechanism 2. The ends of the main tube 1 and segment tube 4 are aligned with the connecting port 201. The connecting port 201 is pushed so that the locking block 205 slides into the circular groove 203 along the inclined surface 206. Subsequently, the elastic force of the elastic ring plate 202 drives the locking block 205 to fit tightly. Then, the rough layer 207 enhances the friction to prevent loosening, while the sealing gasket 204 ensures that the connection part is sealed. At the same time, the unused interface is sealed by the sealing plug 24 of the double-port universal connector 6. After the basic assembly is completed, the data cable 10 is connected to the external display device through the camera-specific connector 23 to check whether the image of the high-definition camera 26 is clear. Then, before intubation, the equipment was debugged. The high-definition camera 26 at the tube tip 5 was turned on to observe the real-time image and confirm that the field of vision was normal. The inflation and deflation functions of the occlusion balloon 3 were tested through the bronchial balloon indicator balloon 18 to ensure that it could expand and contract normally. Subsequently, the first handle plate 17 and the second handle plate 22 were operated to check whether the sealing caps of the suction tube 7 and the camera flushing tube 9 opened and closed smoothly. Then, it was observed whether the elastic clamping ring 14 could effectively deform in the concave annular groove 13 to achieve a seal. Then, the intubation operation is performed. The medical staff holds the main tube 1 and controls the insertion depth by referring to the scale 11 on the surface. Under the guidance of the ultrasound endoscope, the tube tip 5 is slowly sent into the target bronchus through the esophagus. During the process, the high-definition camera 26 transmits images of the airway in real time, which makes it easy to accurately adjust the direction of intubation and avoid entering the non-target airway. Afterwards, the intubation positioning is completed and the occlusion is implemented. When the tube tip 5 reaches the predetermined position, the occlusion balloon 3 is inflated through the balloon tube 8. The degree of expansion of the bronchial balloon indicator balloon 18 is observed to determine the occlusion status. Subsequently, the occlusion balloon 3 is made to fit tightly against the inner wall of the airway to achieve occlusion and prevent gastric secretions or blood from entering the tube. Subsequently, auxiliary operations are performed according to the needs of the surgery. If there are secretions in the airway, the first sealing cover 16 of the suction tube 7 is opened through the first handle plate 17, the elastic clamp 14 is disengaged from the concave annular groove 13, and the suction head 12 absorbs the secretions through negative pressure. After completion, the sealing cover is closed. If the surface of the high-definition camera 26 is obscured by dirt, the second sealing cover 21 of the camera flushing tube 9 is opened through the second handle plate 22, and flushing fluid is injected through the camera flushing connector 19. The flushing fluid is sprayed out through the round hole 27 at the tube end 5 to clean the camera or to flush the area to be cleaned in the patient's stomach, ensuring a clear field of vision and a clear surgical area in the stomach. When ventilation or medication is performed later, the sealing plug 24 corresponding to the double-port universal connector 6 is opened and the corresponding equipment is connected for operation. Finally, after completing the operation and removing the kit, the gas inside the balloon 3 is released through the balloon tube 8 to cause it to contract and detach from the airway wall. Then, the connection between the high-definition camera 26 and the external device is turned off, and the intubation kit is slowly pulled out. During disassembly, the main tube 1 and the segment tube 4 are pulled in the opposite direction to cause the locking block 205 to compress the elastic ring 202 and deform it to detach from the circular groove 203. The components are then separated, cleaned, and disinfected for future use.
