At this time, the bulging part will remain in the cloaca of the female Chinese soft-shelled turtle. Spillover, since one female corresponds to one bulge, it can prevent cross-infection between females and improve the fertilization rate.

Preferably, a drawstring is provided on the enlarged portion. The drawstring is used to pull the bulge out of the cloaca.

Preferably, the shunt chamber is T-shaped or Y-shaped. Due to the unique physiological structure of the female Chinese soft-shelled turtle, two vas deferens are required, so the shunt chamber is used to divide the semen in the vas deferens into two branches, respectively, from the first vas deferens and the second vas deferens into the female Chinese soft-shelled turtle's cloaca.

Preferably, the front ends of the first vas deferens and the second vas deferens are provided with insemination ports. The insemination port facilitates the flow of semen from the vas deferens into the cloaca.

Preferably, the cross section of the main body is in the shape of a half moon. Part of the main body will enter the cloaca of the female soft-shelled turtle along with the enlarged part. Since the cross section of the main body is half-moon-shaped, when the main body enters the cloaca, the two ends of the main body will be stuck in the cloaca, so that the main body will not rotate in the cloaca. , preventing the body from slipping out of the cloaca.

Preferably, the main body is provided with a snap ring at the end away from the enlarged portion. The retaining ring can be used with the insemination gun, and the main body is fixed on the front end of the insemination gun through the retaining ring, which has the advantage of continuous injection.

Preferably, the enlarged portion is in the shape of a cone as a whole. Specifically, the enlarged portion is mushroom-shaped, and the side wall thereof is smoothed by the arc surface, so that the enlarged portion can be easily entered into or taken out from the cloaca.

Detailed ways

The principles and features of the present invention are described below, and the examples are only used to explain the present invention, but not to limit the scope of the present invention.

Example 1:

As shown in Figures 1 to 2, an insemination device for turtles comprises a main body 1, an enlarged part 2, a first vas deferens 3, a second vas deferens 4 and a plunger 5, and the main body 1 is provided with an insemination The semen channel 11, the plunger 5 is located in the semen channel 11, the rear end of the enlarged part 2 is provided with a shunt chamber 6 with a three-way function, and the shunt chamber 6 includes a first through port 61, a second The second port 62 and the third port 63, the first port 61 is connected to the first vas deferens 3, the second port 62 is connected to the second vas deferens 4, the third port 63 The outer sidewall of the insemination channel 11 is in contact with the inner sidewall of the insemination channel 11 , and the shunt chamber 6 is movably connected to the main body 1 .

The plunger 5 is used to push the enlarged portion 2 out of the main body. The rear end of the expansion part 2 is provided with a shunt chamber 6, and the third port 63 of the shunt chamber 6 is movably connected with the main body 1. When the plunger 5 continues to push inward, the entire expansion part 2 will be pushed away from the main body, thereby making the expansion part 2 away from the main body. The part 2 remains in the cloaca and acts as a plug.

The method of use is as follows: inject semen into the insemination channel 11, push the insemination device into the cloaca of the female Chinese soft-shelled turtle, and push the insemination device into the female Chinese soft-shelled turtle's cloaca. When there is obvious obstruction, control the depth of the insemination device, Start insemination; the process of insemination is to slowly push the plunger 5 inward, wait until the plunger 5 is pushed inward to contact the shunt chamber 6, and continue to push the plunger 5 inward until the enlarged part 2 is pushed away from the main body 1, After the bulging part 2 is separated from the main body 1, it will stay in the cloaca of the female Chinese soft-shelled turtle, which acts as a plug to prevent semen from overflowing; after 30 minutes, the bulging part 2 is taken out through the pulling rope 21 provided on the bulging part. One bulge is used for each individual female, which allows for cross-contamination and increased fertilization rates.
