<p>PURPOSE:To enable an inexpert to mount an artificial insemination instrument and inject semen in a womb of a pig securely without giving it an uncomfortable feeling. CONSTITUTION:A semen inject hole 2 is formed in a soft tube member 1 made of silicone as semen's flowing route. A round semen outlet 3 connected to the semen inject hole 2 is formed near the tip of the tube member 1. An expansion membrane 4 made of silicone film is mounted on the periphery of the tube member 1 near the mounting side from the semen outlet 3. Both tips of the expansion membrane 4 are firmly fixed to the tube member 1 near the inside of which is hollow. An air hole 5 is formed in the tube member 1 as a means to fill fluid. The diameter (a) of the tube member 1 is formed to be about 5.3mm, the longitudinal length (b) of the expansion membrane 4 at the time of being expanded is formed to be about 12mm, the length (c) from the side of the tip of the expansion membrane 4 at the time of being expanded to the tip of the tube member 1 is formed to be about 15mm, and the diameter (d) of the expansion membrane 4 at the time of being expanded is formed to be about 25mm.</p> |
