Example (b):
the utility model provides a novel intubate guide optical wand, as shown in figure 1, including flexible light pipe 1, 1 pot head of light pipe is equipped with handle 2, and the 1 other end of light pipe is equipped with illuminator 3, and handle 2 is equipped with reducing fixed stopper 4 towards the one end of illuminator 3, and reducing fixed stopper 4 overlaps on light pipe 1, and reducing fixed stopper 4 is used for the fixed endotracheal tube of different pipe diameters. In order to make the endotracheal tube that the optical wand can the different pipe diameters of adaptation, can dismantle the cover on the light pipe 1 and be equipped with a plurality of adaptation circle 5, adaptation circle 5 can be selected as the elastic rubber circle that the internal diameter is less than 1 diameter of light pipe, fixes and detachably overlaps through self elasticity on locating light pipe 1. The light guide pipe 1 is matched with the tracheal catheters with different pipe diameters by disassembling and replacing the matching rings 5 with different diameters on the light guide pipe 1.
During the use, select suitable adaptation circle 5 cover to locate outside the light pipe 1 according to endotracheal tube's pipe diameter, then locate outside light pipe 1 and adaptation circle 5 endotracheal tube cover to make illuminator 3 be located apart from endotracheal tube front end about 5 millimeters department, overlap endotracheal tube outside reducing fixed stopper 4 towards the port of handle 2 again, can be fixed endotracheal tube. And finally, bending the front end of the light guide pipe 1 far away from the handle 2 by 60 degrees to 90 degrees, bending the endotracheal tube along with the front end, and then holding the handle 2 to perform endotracheal intubation.
In order to enable the light wand to fit endotracheal tubes of different lengths, the light pipe 1 is movable relative to the handle 2 and the variable diameter fixed plug 4 as shown in figures 1 and 2. Specifically, the handle 2 includes the regulation section 21 and the section of holding 22 of cover on the light pipe 1, adjusts the section 21 both ends respectively with fixed stopper 4 of reducing and hold section 22 rotatable coupling. The rotatable connection is that, the both ends face of adjusting section 21 is equipped with a plurality of sliding ball 7 respectively, and the terminal surface that holds section 22 and fixed stopper 4 of reducing and adjust section 21 and be connected is equipped with annular arc spout 6 respectively, and sliding ball 7 holds in the arc spout 6 rather than corresponding and can remove for arc spout 6. Due to the matching of the sliding ball 7 and the arc-shaped sliding groove 6, the reducing fixed plug 4 and the accommodating section 22 cannot be separated from the adjusting section 21.
One end of the light guide pipe 1 close to the handle 2 is provided with a threaded section, the inner surface of the adjusting section 21 is in threaded connection with the threaded section of the light guide pipe 1, the inner diameter of the variable diameter fixing plug 4 and the inner diameter of the accommodating section 22 are larger than the inner diameter of the adjusting section 21, and the length of the accommodating section 22 is not smaller than the length of the threaded section.
