Abstract
Description
- The present utility model refers to a device for slow release of progesterone for veterinary use mainly used for estrus synchronization protocols.
- Devices for low release of progesterone of veterinary use intended in estrus synchronization are already known, comprising a body with material impregnated with progesterone followed by two or more flexible extensions to support the internal walls of the animal vagina. Typically, these devices are applied to the animal body with the aid of an applicator tube and a plunger. The device is inserted into this applicator tube, which therefore has a larger diameter than the device itself. Then, the tube is inserted into the animal's vaginal canal to a depth close to the position wherein the device should remain, close to the cervix. Then, a plunger is pressed inside the applicator tube, pushing the device out of the applicator tube. When the device for slow release of progesterone comes out of the applicator tube, its flexible extensions tend to abut against the animal vaginal canal wall, fixing the device into the desired position. Thus, the applicator tube and the plunger are removed from inside the animal body.
- Usually, this same tube is used to apply another device for slow release of progesterone to another animal. This is because, due to its dimensions and its resistant material, the cost of the tube is considerable and should not be neglected. However, before its reuse it is necessary to wash and sanitize this tube. This does not, however, guarantee the complete sterilization of the tube, remaining a risk of contamination of other animals. In addition, the washing procedure is laborious and costly.
- Additionally, due to their large dimensions, these applicator tubes can hurt the animal body, also increasing the risk of infections.
- In view of the existing problems in the prior art, a device for slow release of progesterone was developed which objectives are to allow application to the animal with no need to use a large reusable applicator with a plunger, and with no need to wash the applicator, with less risk of causing injury to the animal, which allows greater precision of application and positioning within the animal body.
- The objects of the present utility model are achieved by means of a device for slow release of progesterone in an animal comprising a body impregnated with progesterone, two flexible extensions extending from one end of the body, and which ends opposite the body curve in spaced apart, each of the two flexible extensions comprising an eyelet in the portion near the ends curving away from each other, the eyelets of the two flexible extensions being axially aligned with each other with the flexible extensions in an extended position;
a removable tube coupled to the end of the body opposite the flexible extensions; a cable that passes through the inside of the body and the inside of the tube, with a first end close to the flexible extensions being connected to a pin coupled to the eyelets, and a second free end extending out of the body and tube on the side opposite the flexibles extensions; the pin being coupled to the eyelets aligned with the flexible extensions in the extended position; and the pin being actuated by cable and decoupled from the eyelets, with the flexible extensions being unlocked and in a curved position. - For better understanding, the features and advantages of the present utility model will be showed and described together with their respective figures.
-

Figure 7 represents a lower perspective view of the flexible extensions of the device for slow release of progesterone in the locked position with a pin inside the eyelets; -
Figure 8 represents an exploded perspective view of the device for slow release of progesterone which body is consisted of a removable part impregnated with progesterone separated from the support, with the flexible extensions open; -
Figure 9 represents a perspective view of the device for slow release of progesterone according tofigure 8 , with the flexible extensions extended and locked. -
Figure 10 represents a perspective view of the device for slow release of progesterone with the removable part coupled to the support and with the flexible extensions open. - As can be seen in the attached figures, the device for slow release of progesterone, object of the present utility model, consists of a device for slow release of progesterone in an animal comprising a
body 1 at least partially impregnated with progesterone, followed by twoflexible extensions 2 extending from one end of the body. When in the non-tensioned position of these flexible extensions, their ends opposite the body curve away from each other, as can be seen infigure 2 . However, since they are made of flexible material, theseflexible extensions 2 can be tensioned and extended, being parallel to each other, as illustrated infigure 2 . - Each of the two flexible extensions comprises an
eyelet 6 in the portion close the ends curving away. Theeyelets 6 at both ends are axially aligned with each other when the flexible extensions are in the extended position, so that the two eyelets intersect concentrically when theflexible extensions 2 are extended and aligned with thebody 1. - The device also comprises a
removable tube 3 attached to the end of the body opposite the flexible extensions, as illustrated infigure 3 , and acable 4 passing through the inside of thebody 1, better illustrated infigure 4 . This cable also passes through the inside of thetube 3 at the application time of the device for slow release of progesterone to the animal body, as shown infigure 3 . The removable tube preferably has a diameter smaller than the diameter of thebody 1 impregnated with progesterone. - The end of the
cable 4 close to the flexible extensions is connected to apin 5 intended to be coupled to theeyelets 6. The opposite end of the cable is a free end extending out of thebody 1 andtube 3 on the side opposite the extensions. This free end will be used to pull the device for slow release of progesterone out of the animal body after use. - In a first position of the device, the
flexible extensions 2 are tensioned and stretched, with theeyelets 6 aligned. Thepin 5 is then coupled inside the two aligned eyelets, as shown infigures 3 and5 . In this position, theflexible extensions 2 are in the tensioned and extended position, parallel to each other, which facilitates the device application inside the vagina of the animal. - The device application to the animal body is performed with the
flexible extensions 2 tensioned and stretched, introducing the applicator device on the side of the flexible extensions inside the animal vaginal canal, and pushing the device inwards to the ideal depth, for example, close to the cervix, with the aid of theremovable tube 3. A part of thehandle 4 remains exposed outside the animal vagina even after the device is introduced. - Then, after the device is correctly positioned, the cable is activated, pulling it out of the
removable tube 3 untilpin 5 is detached from theeyelets 6, unlocking theflexible extensions 2. At that moment, theflexible extensions 2 are detached, and their extremities tend to return to the curved position away from each other, supporting each other and exerting pressure inside the animal body responsible for fixing the device in the ideal position. - After the
flexible extensions 2 are unlocked and the device is subsequently secured, theremovable tube 3 is detached from thebody 1 by pulling it lightly, so that the free end of thehandle 4 remains exposed outside the animal vagina. This allows the device to be removed simply after the end of the estrus synchronization procedure, simply by pulling the device out of the animal vagina by the free end of thecable 4. -
Removable tube 3 is preferably made of disposable, lightweight and low-cost material and cannot be used with other devices for slow release of progesterone, thus reducing the overall cost of the product and the risk of contamination. -
Body 1 can be made as a single piece with openings, as shown infigures 3 and 4 . - Alternatively, and as shown in
figures 8 and9 , thebody 1 can be comprised of asupport 12 and adetachable piece 11 impregnated with progesterone coupled around thesupport 12. The removable piece is preferably a cylinder made of polymeric material. Because thispart 11 is removable, this allows it to be discarded and replaced with a similar newremovable part 11. In this way, the device for slow release of progesterone according to the present model can be easily reused several times, being only necessary to sterilize it and replace theremovable part 11 with a new part. - This embodiment of the
body 1 is particularly advantageous, since the device can be partially reused, cleaning thesupport 12 withflexible extensions 2 and using a newremovable tube 3 and a newremovable part 11 impregnated with progesterone. - In addition, in any of the alternatives shown in the present model, there is no need to previous wash and sanitize any additional equipment for application of the device to the animal. The risk of injury to the animal is also reduced with this new model of device for slow release of progesterone. This is because the state-of-the-art applicator presses, by means of a plunger, the device impregnated with progesterone against the animal vaginal wall, therefore, if care is not taken with the applied force and depth, injuries can be caused. In addition, the applicator tube used in the state of the art has dimensions larger than the device itself, which can also cause injuries when it is introduced into the animal vagina.
- The present utility model reduces this risk, since the application of the device is performed by guiding the device itself inside the vaginal canal with the aid of the removable tube that is also part of the device, therefore, with no need to apply a force of plunger against the animal to release the body with progesterone. In addition, the
removable tube 3 has dimensions smaller than the progesterone-impregnated body itself, and smaller than the state-of-the-art applicator tubes, which also contributes to reducing the risk of injury. - Furthermore, the embodiment of the device according to the present model, which is handled and guided directly by the removable tube, being exempt of large tubes and plungers, allows for the person applying the device inside the animal body to have a greater sensitivity in the application, consequently having a better idea of the depth at which the device is being applied, and better precision in its positioning.
