<p>PROBLEM TO BE SOLVED: To provide an injector for fertilized egg capable of improving a conception rate of fertilized egg by inhibiting discharging of the fertilized egg injected into corpus uteri from the corpus uteri.SOLUTION: A fertilized egg injector 1 for fertilized egg/sperm comprises: a guide tube 2 for insertion into corpus uteri, an injection tube 3 inserted into the guide tube 2, and a nozzle body 4 connected on the tip of the injection tube 3. In the inner section of the nozzle body 4, it is arranged: a first channel 46 which linearly extends from the end side to the tip side up to the middle position therebetween in a section from connection cylindrical part 42 to drum part 44; and a second channel 47 which obliquely and linearly extends from the first channel 46 to the tip side of the nozzle body 4 has an opening as a nozzle hole 48 on the side surface of the nozzle body 4. It is also arranged a stopper part 45 on the peripheral surface of the nozzle body 4, in which the size of external diameter is continuously enlarged from the end side to the tip side.</p> |
