Detailed ways

The technical solutions of the present invention are further described below, but the scope of protection is not limited to the description.

As shown in Figure 1, Figure 2, Figure 3, a bovine in vivo embryo extraction device, comprising a collection bottle 1, a tee tube A2, a steel core 3, a flushing tube 4, and a syringe A5, the upper part of the collection bottle 1 is provided with Cover body 6, the tee pipe A2 is in a T-shaped structure, the lower end of the tee pipe A2 passes through the upper part of the cover body 6 and extends into the collection bottle 1, the syringe A5 is connected with one end of the tee pipe A2, and the tee pipe A2 is another. One end is connected with one end of the steel core 3 through the connecting pipe 7, and the other end of the steel core 3 is inserted into the egg flushing tube 4, the steel core 3 is a steel thin steel pipe, and the outer diameter of the steel core 3 is the same as the inner diameter of the egg flushing tube 4, The three-way pipe A2 is provided with two one-way valves 8 .

When the bovine embryo is extracted, the steel core 3 is inserted into the oviduct 4 to enhance the hardness of the oviduct 4, so that it can be inserted into the uterus of the bovine. Air to inflate the air bag 14, and the oviduct 4 will be stuck in the uterus of the cow, then the valve A15 is closed, and then the oviduct fluid is injected into the tee tube B through the syringe B12, and the oviduct fluid enters the oviduct through the connecting pipe 7. In the tube 4, after the injection of the syringe B12 is completed, open the valve A15, and then continuously pull the syringe A5, the two one-way valves 8 in the three-way tube A2, one only allows the egg flushing liquid to enter the three-way tube A2 from the connecting tube 7, One only allows the egg-flushing liquid in the three-way tube A2 to enter the collection bottle 1, so that through the cooperation of the two one-way valves 8, the egg-flushing liquid can be continuously extracted from the uterus of the cow and flow into the collection bottle 1. to collect and improve work efficiency.

The connection between the three-way pipe A2 and the connecting pipe 7 and the end of the three-way pipe A2 inserted into the cover 6 are provided with a one-way valve 8. When the syringe A5 is pulled open, the one-way connection between the three-way pipe A2 and the connecting pipe 7 is in one direction. The valve 8 is in an open state, and the one-way valve 8 at one end of the three-way tube A2 inserted into the cover body 6 is in a closed state, so that the egg-washing liquid enters the three-way tube A2; when the syringe A5 is squeezed, the three-way tube A2 is connected to the The one-way valve 8 at the connection of the tube 7 is in a closed state, the one-way valve 8 at one end of the three-way tube A2 inserted into the cover 6 is in an open state, and the egg flushing liquid in the three-way tube A2 is pushed into the collection bottle 1 for collection. .
