Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer tank technology, specifically a sampling transfer tank. Background Technology
[0002] In scientific research, medical fields, and other areas, it is often necessary to temporarily store and transport refrigerated samples. For example, in biological experiments, cell and tissue samples obtained from experimental equipment need to be kept at low temperatures to maintain sample viability before being sent to testing instruments or further processing stages; in medical testing, blood, urine, and other samples collected also need to have a stable storage environment when sent to different departments for testing. Existing containers used for short-term refrigerated sample storage have several problems. Most ordinary containers lack effective insulation measures, making it difficult to maintain a cooling atmosphere for extended periods. Samples are easily affected by external temperatures, causing them to heat up and leading to a decline in sample quality or even loss of research or testing value.
[0003] Some containers with simple insulation functions have fixed internal structures, making it difficult to adapt to the storage needs of samples of different shapes and sizes. Utility Model Content

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example: See Figures 1 to 7 This utility model provides a sampling transfer container, including a container body 1. A sample rack 2 is placed inside the container body 1. The sample rack 2 includes symmetrically arranged support legs 21. The outer walls of the support legs 21 are symmetrically provided with teeth 22. Each support leg 21 has multiple adjustment frames 3 fitted on its outer wall. The number of adjustment frames 3 on one side of the support leg 21 can be set as needed. For better illustration, only 3 adjustment frames 3 are shown on one side of the support leg 21 in the schematic diagram. An adjustment mechanism 4 is provided inside the adjustment frame 3 for fixing the adjustment frame 3 on the teeth 22 at different heights and adjusting the gap between the upper and lower adjustment frames 3. A sample placement mechanism 5 is provided on the adjustment frame 3 for placing and fixing the sample tube.
[0020] Furthermore, the adjustment mechanism 4 includes a first slide 40, a track cavity 41, and a second slide 42 that are connected within the adjustment frame 3. The second slide 42 is located on the side of the adjustment frame 3 away from the sample placement mechanism 5. There are two track cavities 41, which are symmetrically located on both sides of the first slide 40. The inner wall of the first slide 40 is connected to a first slider 47 by a first spring 44. The second slide 42 is connected to a second slider 45 by a second spring 43. The mechanism also includes a rope 46, one end of which is fixed to the second slider 45 on one side, and the other end of which is fixed to the second slider 45 on the other side. The rope 46 passes through the inner surface of the first slider 47.
[0021] Furthermore, the sample rack 2 includes a V-shaped frame 23 located at the top of the support leg 21. The V-shaped frame 23 is made of elastic material. The upper opening of the transfer tank body 1 is symmetrically provided with storage slots 24. The two ends of the V-shaped frame 23 are respectively locked onto the storage slots 24 on both sides. Sample racks 2 of the same specifications can be placed side by side in one transfer tank body 1. For better placement, the three sample racks 2 are slightly different: 1. The V-shaped frame 23 of the sample rack 2 placed in the middle is located in the middle position of the support leg 21; 2. The V-shaped frame 23 of the sample rack 2 placed on the left is located on the right side of the support leg 21; 3. The V-shaped frame 23 of the sample rack 2 placed on the right is located on the left side of the support leg 21. When placing the sample racks 2, the sample racks on the left and right sides should be placed first, and then the sample rack 2 in the middle should be placed. Here, for better explanation of the principle, only the sample rack 2 located in the middle is shown.
[0022] Furthermore, the sample placement mechanism 5 includes a rotating shaft 50 rotatably mounted on the adjustment frame 3. An inverted T-shaped upright plate 51 is fixedly provided at the end of the rotating shaft 50. The bottom of the inverted T-shaped upright plate 51 is provided with symmetrical slots 52. A sample placement platform is inserted into the slot 52. The sample placement platform is made of foam board material. The sample placement platform 53 is provided with an opening for placing a sample tube. The sample placement platform 53 is inserted into the slot 52. The sample placement platform 53 is made of foam board material. The sample placement platform 53 is provided with an opening 54 for placing a sample tube.
[0023] Furthermore, a cross-shaped opening is provided at the center of the sample placement stage 53.
[0024] Furthermore, a slotted opening is provided at the outer edge of the sample placement stage 53.
[0025] Furthermore, the bottom of the inverted T-shaped upright plate 51 and the slot 52 are provided with symmetrical positioning pins 55, which are parallel to the slot 52.
[0026] Furthermore, one end of the positioning pin 55 is fixed to the inverted T-shaped upright plate 51, and the other end is a spike 56, which is used to insert into the sample placement stage 53 for positioning. The friction between the positioning pin 55 and the foam board strengthens the fixation of the sample placement stage 53.
[0027] Furthermore, the rotating shaft 50 is connected to the adjusting frame 3 via a torsion spring; Furthermore, the transfer tank body 1 includes an outer shell 6 and an inner liner 7 connected by an inner and outer sleeve. The bottom opening of the outer shell 6 is provided with a bottom cover 8, and the top opening of the outer shell 6 is provided with a top cover 9. Existing sealing technologies are used at all joints to prevent leakage. When storing different types of samples, a suitable inner liner 7 can be quickly replaced, facilitating cleaning and disinfection of the inner liner 7 and preventing cross-contamination of samples. The cavity 10 between the outer shell 6 and the inner liner 7 is filled with a cold storage medium. A replenishment port 11 is provided on the outer shell 6 and at corresponding positions in the cavity 10, allowing replenishment of the cold storage medium after its consumption. The cold storage medium can be a specially formulated ice-salt mixture or a high-performance cold storage gel, both existing technologies. These cold storage media can absorb and store a large amount of cold energy in low-temperature environments. When the external temperature rises, causing the temperature of the inner liner 7 to rise, the cold storage medium releases cold energy to cool the inner liner 7, thereby maintaining a stable cooling atmosphere inside the tank. The cavity 10 can be evacuated to a vacuum state to improve the insulation effect. When the cooling capacity of the cold storage medium is exhausted, it can be easily replaced or replenished to ensure that the transfer tank continues to maintain good cooling performance.
[0028] The specific implementation method is as follows: In use, liquid nitrogen is poured into the inner liner 7 through the upper opening 54. First, the gap between two adjacent adjustment frames 3 on the same side support leg 21 is adjusted according to the length of the sample tube so that the gap between the upper and lower adjustment frames 3 can accommodate the sample tube. The adjustment process is as follows: When slider 47 is pressed into groove 40, spring 44 is compressed. Through the cooperation of the track cavity and groove 40, rope 46 bends along the inner surface of slider 47 and tightens towards slider 47. The other end of rope 46 pulls slider 45 into groove 42, and spring 43 is compressed. Slider 45 disengages from the gap between two adjacent teeth 22, thus pushing the adjustment frame 3 upward or downward. After reaching the desired position, slider 47 is released. The elastic force of spring 44 drives slider 47 away from groove 40 and resets it. The elastic force of spring 43 drives slider 45 away from groove 42 and resets it. Slider 45 then re-enters the gap between two adjacent teeth 22 at the same height. At this time, half of slider 45 is located in the gap between two adjacent teeth 22, and the other half is located in groove 42, thus fixing the position of adjustment frame 3. Sample tubes of different lengths can be placed for storage.
[0029] Secondly, there are two types of openings 54 on the sample stage 53 used in conjunction with itself. The difference between the two is that one sample stage 53 has a cross opening at the center and the other sample stage 53 has a straight opening at the edge. The two types of openings 54 can be selected according to the radius of the sample tube to be fixed. The key point is that they are not limited by the shape of the sample tube opening and can be round or square.
[0030] When the radius of the sample tube is within the maximum placement range of the slot, after inserting the sample stage 53 with the cross opening into the slot 52, the sample tube can be inserted into the cross opening of one of the sample stages 53. When the radius of the sample tube exceeds the maximum placement range of the slot, after inserting the sample placement stage 53 with the slot into the slot 52, on the same sample rack 2, take an adjustment frame 3 on the left side of the support leg 21 and an adjustment frame 3 on the right side of the support leg 21 at the same height. The two sample placement stages 53 at the same height cooperate with each other, and place the sample tube between the two sample placement stages 53. The edge of the sample tube is symmetrically placed in the slot on both sides, thus completing the fixation of the sample tube. Sample tubes of different radii can be placed for storage.
[0031] Third, when placing the sample tube, the top should ideally not exceed the pivot 50. After placing the sample tube on the sample holder 2, insert the sample holder 2 into the transfer container body 1 through the upper opening 54 of the inner liner 7. Simultaneously, pinch the V-shaped frame 23 inwards. After the V-shaped frame 23 deforms, place its end in the storage slot 24 to complete the fixation of the V-shaped frame 23. Traditionally, the sample holder 2 is fixed using a lifting rod, which includes a metal bar with a downward-curving hook at the top. This hook hooks onto the upper opening 54 of the inner liner 7 for fixation. This method causes the sample holder 2 to wobble during handling, which can interfere with the sample. Using the V-shaped frame 23 for fixation improves the stability of the sample holder 2, thereby reducing interference factors on the sample inside the sample tube and ensuring the accuracy of the experiment.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
