Objective To explore the performance and its application prospect of self-made improved light guided endotracheal catheter in the training of dummy tracheal intubation． Method Based on the structure of ordinary tracheal intubation duct，using excellent plastic material of median hardness，the optical fiber were implanted into the duct’s wall，and the input and output outlet were connected with separately the spectroscope and the condense． The drive pipe external tap end solidification bringing photosource sent out the light and through spectroscope，the optical fiber，the condenser illuminated and illuminated front region of the duct and make the intubation process gas channel illumination to be sufficient． According to the clinical commonly used trachea drive pipe specification and the disinfection standard system，the light guide drive pipe was made． 8 emergency doctors were chosen to carry out the trachea intubation training on dummy，each inserted a tube 100 times，average per person intubation success ratio，average per person each time intubation time were recorded and compared with the control group． Results First time succession were received in 87 － 96 example in the improved group，per capita 93． 5 example; with a success rate of 87 to 96 per cent and per capita 93． 65% each time，and per capita intubation time 11． 59 ± 0． 38 s，as compared with 83 － 95 successful example，per capita 89 example; success rate of 83 to 95 per cent and per capita 90． 03 % per capita per year，and 13． 14 ± 0． 38 s intubation time in the control group，respectively． There existed statistical significant difference in homosexual indicators between the two groups ( all P ＜ 0． 01 ) ． Conclusion The self-made improvedlight guide trachea drive pipe has the advantage of operation convenience，high intubation success ratio，and less time consumption，and is worthy of the clinical discussion．
