Description

Изобретение относится к области сельского хозяйства и может быть применено в практике искусственного соединения сельскохозяйственных животных .The invention relates to the field of agriculture and can be applied in the practice of artificial compounding of farm animals.

Известно устройство, состоящее из' трубки с отбортованным внутрь концом и толкателя, расположенного внутри трубки [1J. Трубка также как и толкатель в продольном сечении имеет сужение .A device is known consisting of a tube with a flanged inward end and a pusher located inside the tube [1J. The tube as well as the pusher in the longitudinal section has a narrowing.

Устройство используется для осеменения животных.The device is used for insemination of animals.

Простерилизованное в заводских условиях устройство извлекают из пакета, после чего в трубку помещают простерилизованную гранулу в оболочке и толкателем перемещают ее до переднего упора. Затем конец устройства вводят в половые пути животного мано-цервикально и нажимают на толкатель,., При этом эластичная оболочка гранулы уплотняет зазор.между толкателем и трубкой. Передняя часть оболоч2 ки гранулы прорывается, и содержимое, (сперма) полностью впрыскивается в половые пути.The device sterilized in the factory is removed from the bag, after which the sterilized granule is placed in the tube in the shell and the pusher is moved to the front stop. Then the end of the device is introduced into the genital tract of the animal mano-cervically and pressed on the pusher,., In this case, the elastic shell of the granule seals the gap between the pusher and the tube. The front part of the pellet membrane erupts, and the contents (sperm) are completely injected into the genital tract.

При осеменении коров и телок ректо- или визо-цервикальным способами к устройству подсоединяют специальный удлинитель.When inseminating cows and heifers by recto- or viso-cervical methods, a special extension cord is connected to the device.

Удлинитель состоит из металлического трубчатого корпуса, снабженного с одной стороны круглым фланцем для его фиксации и проволочного стержня с дисковым упором. Удлинитель зачехляют полимерным чехлом.The extension cord consists of a metal tubular casing, equipped on one side with a round flange for fixing it and a wire rod with a disk stop. The extension cord is sheathed with a polymer case.

Использование устройства с удлинителем осуществляют в следующей последовательности. Предварительно прос-. терилизованный удлинитель зачехляют стерильным чехлом из полиэтиленовой трубки. В канал одноразового устройства вкладывают гранулу со спермой и проталкивают ее вкладышем длиной 3 см (вкладышем является часть полиэтиленового толкателя устройства, отрезанного стерильными ножницами).Using a device with an extension cord is carried out in the following sequence. Pre-pros. The sterilized extension cord is sheathed with a sterile plastic tube cover. A granule with sperm is inserted into the channel of the disposable device and pushed with a 3 cm long insert (the insert is part of the polyethylene pusher of the device cut off with sterile scissors).

Подготовленное таким образом устройст.в.0. .подсоединяют к зачехленному удлинителю, вводят в шейку матки и сперму выдавливают в цервикальный канал. После осеменения инструмент вместе с чехлом --удаляют, а удлинитель используют для последующих осеменений.Prepared in this way, device 0. are connected to a sheathed extension cord, inserted into the cervix and the sperm squeezed into the cervical canal. After insemination, the instrument together with the cover is removed, and the extension cord is used for subsequent inseminations.

Однако это устройство не обеспечивает асептического введения его в половые пути самок, так как загрязняется микрофлорой окружающей среды (нестерильным воздухом лаборатории и манежа пункта искусственного осеменения, микрофлорой влагалищной слизи и т.п.), которая затем вводится вместе с устройством в шейку матки и инфицирует последнюю, что может являться прямой причиной возникновения и распространения различного рода забо-‘ леваний половых путей животных и снижения их оплодотворяемости. Это значительно снижает эффективность использования для искусственного осеменения животных спермы в облицованных гранулах.However, this device does not provide for its aseptic introduction into the female genital tract, as it is contaminated with the microflora of the environment (non-sterile laboratory air and the artificial insemination arena, vaginal mucus microflora, etc.), which is then introduced into the cervix with the device and infects the latter, which may be a direct cause of the occurrence and spread of various kinds of diseases of the genital tract of animals and a decrease in their fertility. This significantly reduces the effectiveness of using artificial insemination of animal sperm in lined granules.

Конструктивное несовершенство инструмента ведет в усложнению работы техников осеменаторов из-за ненадежности крепления устройства к уднителю, которые часто рассоединяются в момент нажатия на стержень удлинителя и травмируют половые пути самок, громоздкость инструмента затрудняет введение его в шейку матки, особенно молодых животных, а сборка инструментов связана с дополнительными манипуляциями на изготовление вкладыша из толкателя при ректо- и визо-цервикальном способах осеменения.The structural imperfection of the instrument complicates the work of the insemination technicians due to the unreliable attachment of the device to the extender, which often disconnect when the extension cord is pressed and injure the genital tract of the females, the bulkiness of the instrument makes it difficult to insert it into the cervix, especially young animals, and the assembly of the instruments is connected with additional manipulations on the manufacture of the insert from the pusher during recto-and vizo-cervical insemination methods.

Кроме того, изготовление известного устройства связано с дополнительными затратами на неэкономное расходование сырья (полимерных материалов) .In addition, the manufacture of the known device is associated with additional costs for the uneconomical consumption of raw materials (polymer materials).
