Abstract
Patente de Invenção: "DISPOSITIVO INTRA-VAGINAL PARA PORCAS". Um dispositivo intra-vaginal para porcas, de formato e tamanho adaptados para serem posicionados no trato vaginal, através do anel himenal de um animal (por exemplo, leitoa), para se estender para ambos os lados do anel himenal do animal. O dispositivo, uma vez inserido, libera progesterona a partir de uma matriz impregnada com progesterona em qualquer um dos lados do anel himenal, a superfície que libera progesterona sendo pelo menos 150 cm2 em uma área total. O meio de geometria variável (preferivelmente para o engate de entrada)garante a retenção do dispositivo (por exemplo, por pelo menos 7 a 14 dias) onde, no dispositivo preferido, a carga de progesterona de 1,9 a 2,5 g dentro de 1,2 mm da superfície de liberação pode, mantendo-se um nível de plasma no sangue (que equivale ao nível de plasma no sangue de progesterona superior a 4 ng/mL em um animal sem ovários)garante o início do cio dentro de 3 a 5 dias após a remoção do dispositivo.Invention Patent: "INTRA-VAGINAL DEVICE FOR NUTS". An intra-vaginal device for sows, of shape and size adapted to be positioned in the vaginal tract, through an animal's hymenal ring (for example, gilts), to extend to both sides of the animal's hymenal ring. The device, once inserted, releases progesterone from a matrix impregnated with progesterone on either side of the hymenal ring, the surface that releases progesterone being at least 150 cm2 over a total area. The variable geometry medium (preferably for the input coupling) guarantees the retention of the device (for example, for at least 7 to 14 days) where, in the preferred device, the progesterone load of 1.9 to 2.5 g inside 1.2 mm of the release surface can, maintaining a blood plasma level (which is equal to the progesterone blood plasma level greater than 4 ng / mL in an animal without ovaries) ensures the onset of heat within 3 to 5 days after removing the device.
