Description

Technical Field

[0001] The utility model relates to the technical field of semen preservation, in particular to a temporary semen preservation device. Background Art

[0002] During artificial insemination of animals, semen collected needs to be temporarily stored in a constant temperature chamber. Semen storage not only affects the success rate of fertilization but also directly impacts the quality of the embryo. High-quality semen is the foundation for good reproductive performance. For example, pig semen can be stored at room temperature or cryogenically. Room temperature storage ranges from 15°C to 20°C, with an optimal temperature of 17°C. At room temperature, pig semen can generally be stored for 1-2 days. Cryogenic storage, at a temperature of 0-5°C, allows pig semen to be stored for 5-7 days.

[0003] The current constant temperature box has a simple internal structure, and the containers holding semen are stacked in the constant temperature box. The following problems exist during use: 1. When the semen is placed in the constant temperature box, if the temperature difference between the inside and the outside is too large, the semen will cool down too quickly, which will affect the activity of the sperm. In order to avoid the sudden drop in temperature affecting the activity of the sperm, the container holding the semen needs to be wrapped with a towel before being placed in the constant temperature box to allow the semen temperature to drop slowly. 2. When semen is stored in the constant temperature box for a long time, nutrients and sperm will precipitate and aggregate, resulting in a reduction in the contact area between sperm and nutrients. Therefore, the semen needs to be turned over twice a day, and this operation requires opening the cabinet door, which is not only troublesome but also causes fluctuations in semen temperature. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a temporary semen storage device which is simple to operate, can realize temperature slow drop and perform semen turning operation without opening the cabinet door.

DETAILED DESCRIPTION

[0022] In order to better understand the present invention, Figure 1-Figure 5 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0023] Example 1:

[0024] In this embodiment, the semen temporary storage device includes a constant temperature box 1 and a semen tube rack 2 built into the constant temperature box.

[0025] It should be noted that the thermostat 1 is a conventional thermostat. The only difference is that the back of the thermostat 1 is perforated to provide a through hole for the turntable shaft 202 described below to pass through. The internal structure and principles of the thermostat are the same as those of conventional products. Those skilled in the art can use thermostats of different sizes and styles as needed, and are not limited to those shown in the drawings.

[0026] The semen tube rack 2 includes a turntable 201, a turntable shaft 202 and a plurality of tube sleeves 203 fixedly arranged on the turntable 201. Figure 3 As shown, the turntable 201 is in the shape of a thin plate, preferably made of plastic. Eight tube sleeves 203 are set on the turntable 201. Of course, the number of tube sleeves depends on the size of the constant temperature box, and the arrangement of the tube sleeves 203 is not limited to Figure 3 As shown, an irregular arrangement can also be used. The tube sleeve 203 can be a round tube structure with both ends open, or a structure with an open front end and a closed rear end. The semen tube 204 is placed in the tube sleeve 203. The semen tube 204 and the tube sleeve 203 have an interference fit. After the semen tube 204 is inserted into the tube sleeve 203, the tube sleeve 203 clamps the semen tube 204.

[0027] The front end of the turntable shaft 202 is fixedly connected to the turntable 201, and a screwing handle 205 is provided after the end of the turntable shaft 202 passes through the constant temperature box 1. The turntable shaft 202 is set on the rear wall of the constant temperature box 1 through a bearing 207. Furthermore, sealing baffles can be used on both sides of the bearing 207 to seal and insulate. Specifically, the front end of the turntable shaft 202 is fixedly connected to the turntable 201 as follows: an axial hole 206 is provided at the center of the turntable 201, a keyway 2061 is provided in the axial hole 206, and the front end of the turntable shaft 202 cooperates with the axial hole 206 through a key. An external thread is provided at the front end of the turntable shaft 202 extending out of the axial hole 206. A retaining ring 2021 is provided at the rear end of the turntable shaft 202 located at the axial hole 206. The turntable 201 is fixed to the turntable shaft 202 by a nut.

[0028] In order to improve the stability of the semen tube rack 2, a turntable shaft bracket 208 is further provided in the constant temperature box 1. The bottom of the turntable shaft bracket 208 is fixed in the constant temperature box 1, and the turntable shaft 202 is rotatably provided on the top of the turntable shaft bracket 208. The top of the turntable shaft bracket 208 can be designed as an arc groove structure, and the turntable shaft 202 is located in the arc groove, or it can be provided as a circular ring structure. The turntable shaft 202 passes through the circular ring structure and can rotate in the circular ring structure.

[0029] In order to prevent the turntable 201 from rotating when the semen tube is placed, thereby affecting the operation, and to prevent the turntable 201 from suddenly rotating rapidly when the handle 205 is held and screwed, the utility model provides a damping ring 2081 at the upper end of the turntable shaft bracket 208, and the turntable shaft 202 is located in the damping ring 2081. The inner side of the damping ring 2081 is provided with an anti-slip friction layer, or an elastic plastic ring is used to clamp the turntable shaft 202. With this design, there will be a certain resistance when the turntable shaft 202 is rotated, and rapid rotation will not occur.

[0030] Example 2:

[0031] This embodiment improves upon the first embodiment by adding a buffered cooling device. Specifically, the outer layer of the semen tube 204 is covered with a slow-down insulation sleeve 209, which can be made of fabric or foam. To prevent the dual effects of the tube sleeve and the slow-down insulation sleeve 209 from causing the semen temperature to drop too slowly, the present invention further provides a plurality of through-holes 2031 in the tube sleeve 203 to ensure contact between the slow-down insulation sleeve 209 and the air inside the incubator.

[0032] In order to prevent the head of the semen tube from coming into contact with cold air, which would cause the semen in the head to cool down too quickly, a blocking cap 2032 is provided on the tube sleeve 203 . A slow-falling heat-insulating layer is provided inside the blocking cap 2032 . The slow-falling heat-insulating layer is made of foam or velvet.

[0033] After using the blocking cap 2032, in order to facilitate the removal of the semen tube, a spring 2033 is provided at the bottom of the tube sleeve 203. When the semen tube is pressed into the tube sleeve 203, the spring 2033 is compressed. When the blocking cap 2032 is opened, the semen tube 204 is partially pushed out under the action of the spring 2033, thereby facilitating removal.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
