Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The invention aims to provide a special tool for extracting frozen semen in a pasture, which can quickly extract the frozen semen in a thin tube at the opening of a liquid nitrogen tank, reduce the waste of the frozen semen caused by inflexible operation of long tweezers and avoid the damage or even direct death of the frozen semen.
The frozen semen extractor provided by the invention is explained in detail below with reference to the accompanying drawings.
Fig. 1 shows a schematic structural diagram of a frozen semen extractor according to the present invention, referring to fig. 1, the frozen semen extractor 100 includes a handheld portion 11 and an extraction portion 12, the extraction portion 12 is fixedly connected to a first end 111 of the handheld portion 11, the extraction portion 12 includes n round bars 121 that are parallel to each other and are uniformly distributed, where n is a positive integer greater than or equal to 2, and the first end of the round bars 121 is fixedly connected to the first end 111 of the handheld portion 11, specifically, an included angle α between the handheld portion 11 and the extraction portion 12 is 90 ° to 120 °, and a specific value of the included angle α can be adjusted according to actual needs.
Because the personal habits of users are different, a person uses the right hand and a person likes the left hand, when the stainless steel barrel is extracted, the frozen semen extracting angle is greatly related to the personal habitual overlooking angle, a person likes the vertical overlooking, and a person is used for adopting various overlooking angles, so that when the frozen semen is extracted, different angles are adopted for extraction, and the included angle α between the handheld part 11 and the extracting part 12 is in the angle range of 90-120 degrees, so that the user can extract the frozen semen more conveniently, quickly and accurately.
The appearance of the extraction part 12 can be cuboid, cylinder, elliptic cylinder and other shapes, and can be set according to actual needs. In the present embodiment, the extraction portion 12 is cylindrical in shape. Fig. 2 shows a schematic cross-sectional view of the extraction section 12.
Through a large number of experiments of the inventor, the diameter D of the cross section of the extraction part 12, the diameter D and the number n of the round rods and the diameter D of the frozen semen container are obtained0When the frozen semen extracting device is arranged according to the following relational expression, the target frozen semen can be extracted quickly and safely:
D2/2<nd2+3d0 2<D2。
in order to safely extract the target frozen semen without affecting other frozen semen containers, the diameter D of the cross section of the extraction portion 12 is 5mm to 10mm, for example, D is 6 mm. Specifically, the extraction part 12 includes 12 to 60 evenly distributed round bars 121, for example, in the present embodiment, the number of the round bars 121 is 14. The diameter d of the round rod 121 is 1mm to 1.2mm, and the length h is 100mm to 150mm, for example, the diameter d of the round rod 121 may be 1mm, and the length h may be 120 mm.
Since the frozen semen storage environment temperature is low, the frozen semen extractor 100 of the present invention has a certain requirement on the flexibility of the round bar 121 of the extraction part 12. The ptfe plastic can resist a low temperature of-190 ℃ and has good flexibility at the low temperature, so in this embodiment, the round rod 121 is made of the ptfe plastic.
The shape of the hand-held portion 11 is not strictly required, and it is sufficient to have sufficient strength and to be convenient for holding or holding by hand, and may have a structure such as a long strip, a long column, a handle, and the like. For example, in this embodiment, the material of the handheld portion 11 is cylindrical plastic rod with a diameter of 40-50 mm, the material is easy and convenient to obtain, and the heat transfer performance of the plastic is low, so that the handheld portion is suitable for being held by hands. Specifically, the hand-held portion 11 needs to have a sufficient hand-holding space, and therefore, the length L of the hand-held portion 11 may be 150mm to 200 mm.
In addition, the frozen semen extractor 100 of the present invention further comprises a connecting portion 13, wherein the connecting portion 13 is fixedly disposed at the first end 111 of the handheld portion 11, and the extracting portion 12 is fixedly connected with the connecting portion 13. in this embodiment, the connecting portion 13 is made of rubber, and since the rubber itself has superior flexibility, a span between 90 ° and 120 ° of an included angle α between the handheld portion 11 and the extracting portion 12 can be easily achieved.
All the frozen semen containers are arranged in a stainless steel barrel, the stainless steel barrel is arranged in a liquid nitrogen tank, and each stainless steel barrel can contain 25-100 thin tubes of frozen semen. The stainless steel barrel is provided with a long handle, one end of the stainless steel barrel is bent and hung on the edge of the opening of the liquid nitrogen tank, and the stainless steel barrel is placed below the liquid nitrogen surface. When frozen semen is taken, the long handle of the stainless steel barrel is lifted by hands to the opening of the tank, and then the thin tube frozen semen can be taken.
When extracting frozen semen, the second end of the hand-held part 11 is held by hand, and the extraction part 12 is opposite to the liquid nitrogen tank opening to prepare for extraction. When the stainless steel barrel in the liquid nitrogen tank is lifted to the position of 10cm of the tank opening, the target frozen semen container is rapidly grabbed and lifted by utilizing the friction force between the round rod 121 and the frozen semen container within 5 s. Only one frozen semen can be extracted at a time, and the angle of extraction is matched with the angle of the stainless steel barrel according to the angle of the hand holding the frozen semen extractor 100 (which can be adjusted by the connecting part 13). Soaking the extracted frozen semen in 30-35 deg.C warm water, and thawing for 40 s.
The above-described aspects may be implemented individually or in various combinations, and such variations are within the scope of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Finally, it should be noted that: the above examples are only for illustrating the technical solutions of the present invention, and are not limited thereto. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
