Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
As shown in Figure 1, introducing device is penetrated in the illumination of a kind of During Mechanical Ventilation endotracheal tube inwall, comprises the endotracheal tube 1 for mechanical ventilation and union joint 2 thereof, and described endotracheal tube 1 inwall is coated with one deck nano-TiO 2film, described endotracheal tube union joint 2 is provided with side emitting optical fiber 3 is introduced endotracheal tube 1 to carry out light-struck optic fibre fixing device 4 to its inwall, emitting optical fiber 3 front end, described side is provided with the protective sleeve 5 avoiding light directly to front irradiation.
In the present embodiment, the diameter of described side emitting optical fiber 3 is 1.5 ~ 3.5mm, and described side emitting optical fiber 3 is apart from endotracheal tube 1 inner surface 0 ~ 5mm, and described side emitting optical fiber 3 introduces ultraviolet light or visible ray 8 in endotracheal tube 1.
In the present embodiment, emitting optical fiber 3 front end, described side distance endotracheal tube 1 front end 1.5 ~ 3cm, the one end in air flue is inserted in described endotracheal tube 1 front end namely.Conveniently adjustment side emitting optical fiber 3 enters the length in endotracheal tube 1, and all side surfaces of described side emitting optical fiber 3 indicate scale.
In the present embodiment, the other end of described endotracheal tube union joint 2 is connected with the corrugated tubing 6 for inputting fresh gas flow 7.
As shown in Fig. 2 ~ 3, described optic fibre fixing device 4 comprises fixing cell body 41 and tightens cover 42, described fixing cell body 41 is fixedly installed on endotracheal tube union joint 2, described fixing cell body 41 center is provided with the passage 411 for wearing side emitting optical fiber 3, described fixing cell body 41 has several lobe bodies 412 at the arrival end of passage 411, leave gap 413 between adjacent two lobe bodies 412, make lobe body 412 have the space of elastic shrinkage; Described fixing cell body 41 is provided with external screw thread 414 in the outside of lobe body 412, described in tighten cover 42 inner side be provided with the female thread 421 matching with fixing cell body 41 external screw thread 414 inwardly to tighten up lobe body 412 and then fix side emitting optical fiber 3.
In the present embodiment, described endotracheal tube union joint 2 is angle coupling, described fixing cell body 41 can by inlaying, welding, the fixed form such as splicing be arranged on endotracheal tube union joint 2.
In the present embodiment, described fixing cell body 41 in round table-like, described in tighten cover 42 endoporus be round table-like; Be arranged on after on fixing cell body 41 when tightening cover 42, the upper end of described fixing cell body 41 is inwardly tightened up, and namely the angle of inclination of round platform diminishes.
In the present embodiment, described fixing cell body 41 is formed by bottom integrated injection molding by four lobe bodies 412, certainly can also be made up of the lobe body 412 of three, five or other quantity.
