Detailed Implementation

[0023] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1 to 8 The present invention preferably provides the following technical solution: a balloon tube dislodgement structure for endotracheal intubation, comprising: a tube body 111, a balloon tube 112, and a quick-release connector, wherein the quick-release connector is located at the connection between the tube body 111 and the balloon tube 112 and is used for quick dislodgement of the two; the quick-release connector includes an elastic connector and a transmission component located at the end of the tube body 111 and distributed inside and outside; and a hook column structure located at the end of the balloon tube 112, wherein a sealing ring 311 is provided between the hook column structure and the elastic connector, and the hook column structure is inserted into the transmission component for limiting; when the force for pulling out the tube body 111 exceeds the connection force between the hook column structure and the transmission component, the quick-release connector automatically disconnects, and the tube body 111 is dislodged from the balloon tube 112.

[0025] This application addresses the technical problems of airway obstruction and inconvenience in endotracheal intubation caused by the elongation and deformation of the cuffed tube during extubation due to the elasticity and ductility of the material. It designs a device for rapid dislodgement of the cuffed tube, specifically combining... Figure 1 , 2 As shown in Figures 3 and 4, this device is an airbag auxiliary tube, which is used as the airbag inflation and deflation structure for endotracheal intubation. It is known that the tube body 111 and the airbag tube 112 are connected by a quick-release connector. The airbag tube 112 is connected to the airbag on the endotracheal tube. The quick-release connector here can realize the rapid dislodgement of the two tubes and further realize the deflation process of the airbag. This design shortens the average extubation time to less than 30 seconds and greatly improves the extubation efficiency.

[0026] The quick-release connector includes an elastic connector and a transmission component respectively provided inside and outside the end of the tube 111, and a hook column structure provided at the end of the airbag tube 112. The hook column structure is dampedly connected to the elastic connector, and it is also limitedly inserted with the transmission component. When the force of pulling out the tube exceeds the connection force between the hook column structure and the transmission component, the quick-release connector will automatically disconnect.

[0027] The specific removal process of the quick-release connector, combined with Figure 3 , 4 As shown, because the elastic connector on the tube 111 is damped by the hook column structure, and the hook column structure is limited by the transmission component, when the tube 111 is pulled upward, the elastic connector deforms adaptively. At the same time, when the upward pulling force exceeds the connection force between the hook column structure and the transmission component, the hook column structure and the transmission component are adaptively disengaged, thereby realizing the disengagement process of the tube 111 and the airbag tube 112. At this time, the airbag on the endotracheal tube is deflated, improving the extubation efficiency.

[0028] This design, through the use of a quick-release connector, allows for rapid disengagement between the tube body 111 and the airbag tube 112, effectively preventing the tube from stretching and deforming during removal. This improves removal efficiency and safety while reducing the risk of airway obstruction.

[0029] Furthermore, the hook column structure includes a mounting ring 213 fixed to the top end of the airbag tube 112, and a hook column body 214 annularly disposed on the mounting ring 213. Each hook column body 214 consists of a column 2141, a right-angle snap-fit ​​portion 2142 disposed on the column 2141, and a right-angle snap-fit ​​portion 2142 opened at the top of the column 2141.

[0030] Combination Figure 5 , 7As shown in Figure 8, there are several hook column bodies 214, and each hook column body 214 is fixed to the column 2141 and the mounting ring 213. The right-angle locking part 2142 provided on one side of the column 2141 can engage with the transmission component, and the inclined surface 2143 can interact with the transmission component to realize the quick disassembly and quick assembly process of the transmission component and the hook column structure. For details, please refer to the explanation of the transmission component below.

[0031] Furthermore, the elastic connector includes an elastic bladder 211 fixed to the bottom end of the tube body 111, and a connecting sleeve 212 fixed to the elastic bladder 211, wherein a sealing ring 311 is disposed between the connecting sleeve 212 and the mounting ring 213.

[0032] It is worth noting here that the groove on the outer periphery of the sealing ring 311 increases the tightness of its connection with the mounting ring 213. Figure 8 As shown, when the tube body 111 is pulled upward, the connecting sleeve 212 deforms adaptively, thereby realizing the process of separating the transmission component from the hook column body 214 under the premise that the elastic connector is connected to the mounting ring 213. Subsequently, the sealing ring 311 is separated from the mounting ring 213, further realizing the overall tube separation process of the tube body 111 and the airbag tube 112.

[0033] Furthermore, the transmission component includes an assembly ring 216 fixed to the upper part of the connecting sleeve 212, a vertical groove 222 annularly opened on the assembly ring 216 and corresponding one-to-one with the hook column body 214; and a wedge block transmission assembly transversely arranged on the assembly ring 216 and corresponding one-to-one with the vertical groove 222, used for limiting the hook column body 214 after it extends into the vertical groove 222; it also includes a drive assembly connected to the tube body 111, the drive assembly contacting several wedge block transmission assemblies and serving as their drive source.

[0034] This combination Figure 5 , 6 As shown in Figure 8, the assembly ring 216 has a vertical groove 222 corresponding to the hook post body 214. Preferably, both the vertical groove 222 and the hook post body 214 are in four sets. Figure 8 It is known that the wedge block transmission assembly corresponding to the vertical groove 222 of the assembly ring 216 is used for limiting the hook column body 214 after it extends into the vertical groove 222, so as to realize the docking process between the transmission component and the hook column structure, and then realize the docking process between the tube body 111 and the airbag tube 112.

[0035] The drive assembly connected to the tube body 111 further follows the removal operation of the tube body 111, releasing the wedge block transmission assembly from limiting the hook column body 214, thereby realizing the process of disengaging the transmission component from the hook column structure.

[0036] Furthermore, each wedge transmission assembly includes a transverse groove 217 corresponding to the vertical groove 222 opened on the assembly ring 216, and a first wedge 218 and a second wedge 220 respectively disposed at the inner and outer ends of the transverse groove 217. The first wedge 218 and the second wedge 220 are fixed with a transmission frame 223 that extends beyond the vertical groove 222 and is sleeved on the hook column body 214. A spring 219 is connected between the end of the first wedge 218 away from the transmission frame 223 and the inner wall of the transverse groove 217. The end of the second wedge 220 away from the transmission frame 223 is provided with a second wedge surface, and the second wedge surface is connected to the drive assembly. Furthermore, the end of the first wedge 218 near the column body 2141 is provided with a right-angle portion and an inclined portion. The right-angle portion is used to limit the right-angle locking portion 2142, and the inclined portion is adapted to the inclined surface 2143.

[0037] Combination Figure 5 , 7 As shown, the horizontal groove 217 and vertical groove 222 on the assembly ring 216 are interconnected and vertically distributed, while the hook column body 214 can extend into the vertical groove 222. A first wedge 218 and a second wedge 220 are respectively provided at both ends of the horizontal groove 217. A transmission frame 223 is fixed to the opposite ends of the first wedge 218 and the second wedge 220 to facilitate the passage of the hook column body 214. A spring 219 and a second wedge surface are respectively provided at their opposite ends, and the second wedge surface is connected to the drive assembly. Therefore, when the tube 111 is removed, the drive assembly pushes the second wedge 220... Figure 5 The state shifts to the left, and at this time, under the action of the transmission frame 223, combined with... Figure 7 The first wedge 218 is pushed to the left, thereby compressing the spring 219 and separating the right-angle portion of the first wedge 218 from the right-angle locking portion 2142 of the hook column body 214. At this time, the hook column body 214 loses its limiting function, and the tube 111 can be separated from the airbag tube 112.

[0038] When it is necessary to connect the tube 111 to the airbag tube 112, then... Figure 5 In the current state, the column 2141 is inserted into the vertical groove 222 from bottom to top. The inclined surface 2143 where the hook column body 214 is located can contact the inclined part where the first wedge 218 is located and push the first wedge 218 to the left. As the hook column body 214 goes deeper, when the right angle locking part 2142 passes the right angle part where the first wedge 218 is located and locks, under the action of the spring 219, the right angle locking part 2142 can lock with the right angle part where the first wedge 218 is located, completing the locking process of the tube 111 and the airbag tube 112.

[0039] Furthermore, the drive assembly includes a connecting shell 215 fixed to the tube body 111 and located outside the assembly ring 216, and a drive block 2211 fixed to the bottom end of the connecting shell 215 and in contact with the second wedge 220. It also includes a step block 2212 disposed on the side of the drive block 2211 near the second wedge 220. When the connecting shell 215 moves upward, the step block 2212 pushes the second wedge 220 to move inward.

[0040] Combination Figure 5 , 7 As shown, the connecting shell 215 is fixed to the tube body 111, and the driving block 2211 at its bottom can fit against the second wedge 220. When the connecting shell 215 is moved upward, the ladder block 2212 fixed inside the driving block 2211 can push the second wedge 220 as shown. Figure 5 The first wedge 218 is moved to the left, thereby achieving the process of disengaging from the hook column body 214.
