Description

Technical Field

[0001] This utility model relates to the field of baskets for fine tubes of frozen beef, and in particular to a basket for fine tubes of frozen beef. Background Technology

[0002] In cattle breeding, in order to make full use of the genetic resources of excellent bulls, their semen is collected and stored in thin tubes. Multiple thin tubes are placed in an orderly manner in a basket, and the basket is immersed in liquid nitrogen to achieve ultra-low temperature preservation of the sample, so as to ensure the activity of sperm and the stability of genetic material.

[0003] To accommodate different sizes of frozen bovine sperm tubes, baskets are typically designed with a universal design, leaving some space between the tube and the basket. This can lead to collisions between the tube and the basket during extraction. However, frozen bovine sperm tubes are usually quite fragile, making them prone to damage or breakage, which can easily cause cross-contamination. Utility Model Content

[0004] Therefore, it is necessary to provide a basket for frozen beef fine tubes to address the problem that there is a certain space between the thin tube and the basket, which can easily cause collisions between the thin tube and the basket during extraction, leading to damage or breakage of the thin tube.

[0005] Includes: a basket; an anti-sway mechanism, the anti-sway mechanism comprising positioning blocks evenly distributed inside the basket, positioning pads evenly distributed on the surface of the positioning blocks, a bottom pad distributed in a ring fixedly connected to the inner bottom wall of the basket, a soft pad distributed in a ring fixedly connected to the inner wall of the bottom pad, and several springs fixedly connected to one side of the positioning blocks, the other end of the springs fixedly connected to the inner wall of the basket.

[0006] In one embodiment, a guide block is fixedly connected to the top of the positioning block, and the surface of the guide block is curved into an arc shape.

[0007] In one embodiment, the surface of the positioning block has equally spaced perforations, the inner walls of which are concave and arc-shaped. These perforations allow the cold gas from the liquid nitrogen tank to quickly disperse through the basket and positioning block onto the thin tube, achieving cryogenic preservation of the thin tube and ensuring uniform freezing.

[0008] In one embodiment, both the positioning pad and the soft pad have an accordion-like surface.

[0009] In one embodiment, a plurality of protective sleeves are fixedly connected to one side of the positioning block, and the other end of the protective sleeves is fixedly connected to the inner wall of the basket. The surface of the spring is located inside the protective sleeves. By protecting the spring surface with protective sleeves, liquid nitrogen is prevented from adhering to the spring surface, reducing the possibility of rust formation.

[0010] In one embodiment, the inner wall of the basket is fixedly connected with equally spaced fixing rods, and the inner wall of the positioning block is slidably connected to the surface of the fixing rods. The fixing rods limit the movement of the positioning block, preventing it from shifting during lateral movement.

[0011] In one embodiment, the inner wall of the base pad is recessed in the shape of a flat-topped cone.

[0012] In one embodiment, the top of the base pad has annularly distributed through holes, which communicate with the inner bottom wall of the basket. These through holes allow cold air to quickly enter around the thin tube, thus enabling low-temperature preservation of the tube.

[0013] Beneficial effects

[0014] 1. By cooperating with springs, positioning blocks, and positioning pads, the thin tube inside the basket is flexibly clamped. By cooperating with bottom pads and soft pads, the lower end of the thin tube is flexibly clamped, thereby achieving flexible positioning of the entire thin tube. This prevents the thin tube from colliding inside the basket during extraction, thus avoiding damage or breakage of the thin tube and preventing cross-contamination inside the basket, ensuring the safety of the thin tube stored inside the basket.

[0015] 2. The guide block facilitates the guiding of the thin tube to the opposite ends of the two positioning blocks, and the two sets of positioning pads flexibly contact the surface of the thin tube, ensuring the flexible limitation of the thin tube and thus ensuring the safety of the thin tube stored in the basket.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined with Figures 1-5 This invention describes a basket for handling fine tubes used in frozen beef.

[0026] In one embodiment, a basket for beef jerky fine tubes includes: a basket 100; an anti-sway mechanism 200, the anti-sway mechanism 200 including positioning blocks 201 evenly distributed inside the basket 100, positioning pads 202 evenly distributed on the surface of the positioning blocks 201, a bottom pad 204 annularly distributed on the inner bottom wall of the basket 100, a soft pad 205 annularly distributed on the inner wall of the bottom pad 204, and a plurality of springs 203 fixedly connected to one side of the positioning blocks 201, the other end of the springs 203 being fixedly connected to the inner wall of the basket 100.

[0027] It should be noted that the basket 100, positioning block 201, fixing rod 206 and spring 203 are all made of 316 stainless steel, which has the advantages of low temperature resistance, corrosion resistance and good elasticity.

[0028] The basket 100, positioning block 201, fixing rod 206 and spring 203 of 316 stainless steel components have stable mechanical properties in low temperature environment and can withstand the ultra-low temperature of liquid nitrogen without becoming embrittled.

[0029] Semen from breeding bulls is collected using professional methods such as the artificial vagina technique and quickly transported to the laboratory. Microscopic examination is used to assess semen motility, density, morphology, and other indicators, selecting those that meet quality standards. Subsequently, a cryoprotectant containing glycerol and egg yolk is added to reduce damage to sperm from ice crystal formation.

[0030] Using a specialized dispensing machine or pipette, the processed semen is accurately dispensed into bovine frozen semen tubes, ensuring that the volume of semen in each tube is uniform and meets the prescribed standards.

[0031] The seminiferous tubing is sealed using methods such as heat sealing, steel ball sealing, or plastic plug sealing to ensure a tight seal and prevent semen leakage and liquid nitrogen ingress.

[0032] Place the dispensed and sealed sperm tubes in an environment of about 4°C for 1 to 2 hours to allow the cryoprotectant to fully penetrate into the sperm cells and enhance the sperm's resistance to freezing.

[0033] The sperm can be pre-frozen in liquid nitrogen vapor. Generally, it is placed 5-10 cm above the liquid nitrogen surface for 5-10 minutes, and then lowered to 2-5 cm above the liquid nitrogen surface for 5-10 minutes to allow the sperm to gradually adapt to the low temperature environment.

[0034] In this embodiment, pre-frozen thin tubes are placed in the basket 100, with the bottom end of the tubes abutting against the inner wall of the base pad 204. Multiple soft pads 205 abut against the lower end of the tube surface. The elastic force of the spring 203 pushes the positioning block 201 and positioning pad 202 to move laterally, causing the positioning pad 202 to flexibly abut against the tube surface. Following this method, other thin tubes are sequentially placed into the basket 100, thus flexibly limiting the movement of the tubes within the basket 100. Each basket 100 and thin tube is clearly labeled with information such as the breed, number, and collection date of the bull, and detailed records are established for easy retrieval and management.

[0035] Using a long-handled clamp, slowly immerse the basket 100 into the liquid nitrogen tank, ensuring that the basket 100 is completely submerged in liquid nitrogen. This allows for cryogenic preservation of the fine tubes inside the basket 100. Since liquid nitrogen will continuously evaporate, the liquid nitrogen level in the tank should be checked regularly and replenished in a timely manner to ensure that the basket 100 and the fine tubes are always submerged in liquid nitrogen.

[0036] like Figure 4 As shown, a guide block 209 is fixedly connected to the top of the positioning block 201. The surface of the guide block 209 is curved into an arc shape. The surface of the positioning block 201 is provided with equally spaced slots 208. The inner wall of the slots 208 is concave into an arc shape.

[0037] In this embodiment, when it is necessary to remove the thin tube inside the basket 100, the operator should take safety precautions and slowly open the lid of the liquid nitrogen tank to allow the liquid nitrogen vapor inside the tank to dissipate naturally for a while, so as to avoid the liquid nitrogen vapor suddenly gushing out and injuring people when the lid is opened.

[0038] Using the markings and records inside the liquid nitrogen tank, locate the basket 100 containing the target capillary tube. Carefully lift the basket 100 partially out of the liquid nitrogen using a long-handled clamp, but do not lift it completely out of the liquid nitrogen surface. Minimize the contact time between the capillary tube and the high-temperature external environment to prevent rapid temperature changes from damaging the sample inside the capillary tube.

[0039] Using pre-cooled tweezers, quickly pass between the two guide blocks 209 and grasp the required thin tube. The movement should be gentle and accurate to avoid breaking the thin tube. Rotate and pull the thin tube upward to detach it from the surfaces of the two sets of positioning pads 202 and soft pads 205. Quickly transfer the grasped thin tube to a pre-prepared liquid nitrogen cup containing liquid nitrogen for temporary storage, ensuring that the thin tube is always in a liquid nitrogen environment.

[0040] After taking the required thin tubes, immediately and slowly place the basket 100 back into the liquid nitrogen tank, ensuring that the basket 100 is completely submerged in the liquid nitrogen. Gently close the lid of the liquid nitrogen tank, ensuring that the lid is sealed well to reduce the evaporation of liquid nitrogen.

[0041] like Figure 5 As shown, the surfaces of the positioning pad 202 and the soft pad 205 are both accordion-shaped, the inner wall of the bottom pad 204 is recessed into a flat-topped cone shape, and the top of the bottom pad 204 is provided with annularly distributed through holes 210, which are connected to the inner bottom wall of the basket 100.

[0042] like Figure 4 As shown, a number of protective sleeves 207 are fixedly connected to one side of the positioning block 201, and the other end of the protective sleeve 207 is fixedly connected to the inner wall of the basket 100. The surface of the spring 203 is located inside the protective sleeve 207. The inner wall of the basket 100 is fixedly connected to a fixed rod 206 that is evenly distributed. The inner wall of the positioning block 201 is slidably connected to the surface of the fixed rod 206.

[0043] Positioning pad 202, bottom pad 204, soft pad 205, and protective sleeve 207 are all silicone components, which have advantages such as softness and low temperature resistance. In a liquid nitrogen environment, the physical and chemical properties of positioning pad 202, bottom pad 204, soft pad 205, and protective sleeve 207 remain basically unchanged, and there will be no embrittlement or cracking.

[0044] Working principle: The pre-frozen thin tubes are placed into the basket 100, and the bottom end of the thin tubes is guided by two guide blocks 209 and then abuts against the inner bottom wall of the bottom pad 204. Multiple soft pads 205 abut against the lower end of the thin tube surface. The elastic force of the spring 203 pushes the positioning block 201 and the positioning pad 202 to move laterally, so that the positioning pad 202 flexibly abuts against the surface of the thin tube. In the same way, other thin tubes are placed into the basket 100 in sequence, thereby flexibly limiting the thin tubes in the basket 100, so that the thin tubes do not collide in the basket 100 during the extraction.

[0045] It should be noted that the basket 100, positioning block 201, spring 203 and bottom pad 204 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
