Description

Technical Field

[0001] The present application relates to the technical field of frozen semen thawing, and more specifically, to a frozen semen thawing device for breeding. Background Art

[0002] In modern animal husbandry, pig breeding efficiency and genetic improvement are key factors in enhancing industry competitiveness. Among these, frozen semen thawing devices for pig breeding are crucial tools for improving semen storage and utilization efficiency. These devices are designed to rapidly and efficiently thaw semen while minimizing damage to sperm motility and genetic material, ensuring that thawed semen can be used for successful artificial insemination.

[0003] A search revealed a patent document with publication number CN221644916U that provides a frozen semen thawing device for breeding. This device uses a partition to separate a chamber into upper and lower chambers. The lower chamber is filled with warm water for heating. After the thawing liquid is heated, the frozen semen is placed in the thawing liquid and immersed in the warm water for the first stage of thawing. After the first stage of thawing is completed, the vertical rod is quickly raised, allowing the thawing liquid and frozen semen in the glass tube to be removed from the warm water and placed in the upper chamber. The upper chamber's insulation and the residual heat of the thawing liquid then thaw the frozen semen for the second stage of thawing.

[0004] The above-mentioned device cannot shake the thawing liquid and frozen semen in the glass tube when thawing frozen semen, resulting in low thawing efficiency and uneven heating of the frozen semen in the glass tube, which will have an adverse effect on the activity of the semen. In view of this, we propose a frozen semen thawing device for breeding. Utility Model Content

[0025] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] See also Figure 1 and Figure 2 The present application provides a frozen semen thawing device for breeding, comprising an outer sleeve 1, an inner sleeve 2 being slidably inserted in the outer sleeve 1, a placement plate 201 being rotatably connected to the upper part of the inner sleeve 2, preferably, a placement groove 202 being arranged in an inclined shape, a placement groove 202 being provided on the placement plate 201, a water inlet 203 being provided at the bottom of the inner sleeve 2, a telescopic rod 3 being fixedly connected to the bottom of the inner sleeve 2, an installation cavity 101 being provided at the bottom of the outer sleeve 1, a drive motor 4 being installed in the installation cavity 101, an output end of the drive motor 4 extending to the interior of the outer sleeve 1, a telescopic sleeve 5 being fixedly connected to the output end of the drive motor 4, the telescopic sleeve 5 being slidably connected to the telescopic rod 3, and a heating pipe 6 being installed in the outer sleeve 1.

[0027] By injecting water into the outer sleeve 1, the water can enter the inner sleeve 2 through the water inlet 203; the water temperature is controlled between 37°C and 40°C using the heating tube 6, and the glass tube filled with the thawing medium is inserted into the placement groove 202 and immersed in warm water; frozen semen particles are added to the glass tube, and the drive motor 4 is controlled to drive the telescopic sleeve 5 to rotate, and the telescopic sleeve 5 and the telescopic rod 3 are used to drive the placement plate 201 to rotate, so that the glass tube can move in the warm water, thereby increasing the heating uniformity of the frozen semen particles.

[0028] Transparent windows are provided on the sides of both the outer sleeve 1 and the inner sleeve 2, allowing the user to observe the thawing state of the frozen semen particles in the glass tube through the transparent windows. When the frozen semen particles are thawed to the size of millet grains, the inner sleeve 2 is lifted upward, allowing the glass tube to be removed from the warm water, and the residual heat is used to melt the frozen semen particles in the glass tube. During this process, the drive motor 4 can still drive the glass tube to rotate through the telescopic sleeve 5 and the telescopic rod 3. Because the glass tube is arranged at an angle, the thawing medium can shake inside the glass tube, increasing the thawing speed of the frozen semen particles in the glass tube.

A handle 206 is fixedly connected to the upper portion of the inner sleeve 2. An internal thread 102 is provided inside the outer sleeve 1, and an external thread 204 is provided at the bottom of the inner sleeve 2. The outer sleeve 1 and the inner sleeve 2 are threadedly connected via the internal thread 102 and the external thread 204. The user can lift the inner sleeve 2 upward using the handle 206 and rotate the inner sleeve 2 or the outer sleeve 1 to screw the internal thread 102 into the external thread 204, thereby fixing the inner sleeve 2 to the upper portion of the outer sleeve 1.

[0030] In addition, an inner flange 103 is provided on the upper portion of the outer sleeve 1 and an outer flange 205 is provided on the lower portion of the inner sleeve 2, which can prevent the outer sleeve 1 from falling off from the outside of the inner sleeve 2 when the outer sleeve 1 and the inner sleeve 2 slide relative to each other.
