本発明は牛受精卵を子宮に移植するための牛用
受精卵移植器である。DETAILED DESCRIPTION OF THE INVENTION The present invention is a bovine fertilized egg transplanter for transplanting bovine fertilized eggs into the uterus.
牛の受精卵を移植するために従来用いられてい
る器具は、一般に牛用人工授精器を応用したもの
であり、受精卵を無菌的に且子宮内膜を刺激する
事無く子宮角深部へ注入するには限界があり、受
胎率が低くこの欠点を補正した受精卵移植器が関
係分野に於いて待望されていた。 The devices conventionally used to implant fertilized bovine eggs are generally adapted from bovine artificial insemination devices, which inject the fertilized eggs deep into the uterine horns aseptically and without stimulating the endometrium. However, there are limitations in the ability to carry out fertilized egg transfers, and the conception rate is low, so a fertilized egg transplant device that corrects this drawback has been long-awaited in related fields.
本発明の目的は牛受精卵移植による受胎率を向
上させるために、受精卵を無菌的に且子宮内膜を
刺激する事無しに子宮角深部へ注入する事のでき
る器具を提供する事である。 An object of the present invention is to provide an instrument that can inject a fertilized egg deep into the uterine horns in a sterile manner and without stimulating the endometrium, in order to improve the conception rate of bovine fertilized egg transplantation. .

特徴とするものである。 The device according to the present invention has a double-walled pipe whose tip is filled and rolled, and a small hole through which a flexible tube passes is formed in the side of the tip of the inner pipe, and the small hole is filled with a sliding outer pipe. Its main feature is a covered structure.

進める事ができる。 Next, embodiments of the present invention will be described with reference to the drawings. As shown in Figure 1, the cow's uterus has cervical canal 1,
It consists of a uterine body 2 and a uterine horn 3, and since the uterine horn curves midway and descends into the abdominal cavity, when inserting the fertilized egg transplant device 4 into the uterus, it can be advanced to the curved part of the uterine horn.

で高い受胎率の受精卵移植が可能となる。 As shown in FIG. 2, slide the outer pipe 5 toward you to open the small hole 6 in the inner pipe, and as shown in FIG. By propelling the tube, the tube is inserted along the uterine horn that has descended into the abdominal cavity, and by sending air with the syringe 9 connected to the rear end of the tube, the fertilized egg can be sterilized aseptically and without stimulating the endometrium. can be injected deep into the uterine horn, making it possible to transfer fertilized eggs with a high conception rate.
