Description

Technical Field

[0001] This utility model relates to the field of bioengineering equipment technology, and in particular to an assisted reproductive cryopreservation scaffold and refrigeration equipment. Background Technology

[0002] In the field of assisted reproduction, common storage devices for embryos, gametes, and ovarian tissue include cryopreservation rods and cryovials. Both cryopreservation rods and cryovials are loaded with embryos, gametes, or ovarian tissue at room temperature and then rapidly immersed in liquid nitrogen for cooling. When the rod is first placed in the liquid nitrogen, it boils due to the nitrogen absorbing heat from the room-temperature material and the Leidenfrost effect. This boiling process can last from a few seconds to over ten seconds. After boiling subsides, the operator places the rod into the cryovial and stores it in the liquid nitrogen environment for long-term storage.

[0003] In some large reproductive centers, each embryologist may freeze more than ten or even dozens of embryos every day. Waiting for the liquid nitrogen to boil over each time an embryo is frozen is time-consuming and inefficient. Utility Model Content

[0004] This invention provides a cryopreservation auxiliary support and refrigeration equipment to solve the problem of the time-consuming process of waiting for liquid nitrogen to boil over each time the embryos are frozen when freezing more than ten or even dozens of embryos.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] like Figure 1 As shown in the illustration, this application provides a refrigeration device, which includes a cryopreservation auxiliary support 10, a box 20, a cryopreservation pen 30, and a support rod 40. The cryopreservation auxiliary support 10 is used in conjunction with the box 20, which is made of foam box. Foam box has good heat insulation properties. To preserve embryos or oocytes, liquid nitrogen needs to be poured into the foam box. Because cryopreservation tubes are short, operators cannot directly handle them with their hands; a cryopreservation pen 30 is used to extend the tube for easier handling and to prevent frostbite to the operator. After the operator connects the tube retrieval pen 30 to the carrier rod 40 of the cryopreservation tube, and loads the embryo or oocyte into the carrier rod 40 of the cryopreservation tube, the carrier rod 40 is quickly transferred and immersed in liquid nitrogen. At the same time, the end cap of the tube retrieval pen 30 connected to the upper end of the carrier rod 40 is hung in the groove 111 of the cryopreservation auxiliary support 10. Then, the next sample freezing operation is carried out. When the cryopreservation auxiliary support 10 is fully loaded with all samples frozen, the carrier rods 40 are loaded one by one into the body of the cryopreservation tube, and then transferred to the liquid nitrogen tank for long-term storage.

[0034] A limiting protrusion is provided on the tube extractor 30, which makes it easy to attach the tube extractor 30 to the freezer storage auxiliary bracket 10.

[0035] like Figures 2 to 5 As shown, the freezer storage auxiliary support 10 includes a first support plate 11, a second support plate 12, and a clamping plate 13. The first support plate 11 is vertically arranged in use. At least two first support plates 11 are provided and spaced apart. The first support plate 11 serves as the installation base. At least two second support plates 12 are also provided. The second support plates 12 are set on the first support plates 11 and have an angle between them. In use, the bottom surface of the second support plate 12 is the support surface. The two ends of the clamping plate 13 are fixed to the two first support plates 11 respectively. The clamping plate 13 is horizontally arranged. Multiple slots 131 are provided in the length direction (i.e., horizontal direction) of the clamping plate 13. The slots 131 are used to clamp and fix the tube-picking pen 30.

[0036] In this application, two first support plates 11 and two second support plates 12 are provided. In use, the number of first support plates 11 and second support plates 12 can be appropriately increased according to the needs, such as three or four.

[0037] When freezing embryos, the embryologist can place the carrier rod 40 into liquid nitrogen and simultaneously hang the retrieval pen 30, connected to the carrier rod 40, onto the clamping plate 13 of the cryopreservation auxiliary support 10. The clamping slot 131 engages the retrieval pen 30, fixing its position. Since multiple clamping slots 131 are provided on the clamping plate 13, multiple retrieval pens 30 can be engaged. Therefore, regardless of whether the liquid nitrogen boils, the embryologist can continue freezing the next embryo, placing the second carrier rod 40 containing the embryo into the liquid nitrogen and hanging the retrieval pen 30 connected to the carrier rod 40 onto the cryopreservation auxiliary support 10. This process continues until the support is full of carrier rods 40 or all embryos are frozen. After the liquid nitrogen boils, the retrieval pen 30 is used to transfer the carrier rods 40 into their corresponding tubes for long-term cryopreservation. This support system saves time waiting for the liquid nitrogen to boil, allowing the embryologist to freeze more embryos and improving efficiency.

[0038] In one embodiment, the cryogenic storage auxiliary support 10 further includes a crossbeam 14, with both ends of the crossbeam 14 fixed to two second support plates 12 respectively. The crossbeam 14 can prevent the first support plate 11 from shaking and ensure the stability of the structure. The crossbeam 14 can be installed on the second support plate 12 by means of screw fixing or by means of glue fixing. After installation, the crossbeam 14 is located at the side end of the first support plate 11 and can abut against the first support plate 11 to ensure the overall structural stability.

[0039] In one embodiment, the second support plate 12 is a right-angled plate. The right-angled plate and the first support plate 11 can be fixed together by screws or adhesive. After the right-angled plate is fixed, a U-shaped groove is formed between the right-angled plate and the first support plate 11. When the bracket needs to be installed, the U-shaped groove is installed upside down on the side wall of the box 20. To prevent the U-shaped groove from wobbling on the side wall of the box 20 after installation, the width of the U-shaped groove is set to be the same as the wall thickness of the foam box's side wall. During installation, the first support plate 11 can be installed on the inside or outside of the box 20. The distance between the two first support plates 11 can be adjusted according to the actual installation situation.

[0040] A groove 111 is provided at the top of the first support plate 11, and a slot block 15 is provided in the groove 111. The slot blocks 15 are installed in the groove 111 by screws, and the retaining plate 13 engages with the slot blocks 15. Thus, during installation, firstly, the two ends of the retaining plate 13 are engaged with the two slot blocks 131 respectively, then the two slot blocks 131 are placed into the grooves 111 of the two first support plates 11 respectively, and then the slot blocks 15 are fixed to the first support plates 11 by screws. Specifically, a first screw hole 151 is provided on the side wall of the slot block 15, and a second screw hole 112 is provided on both sides of the groove 111. During installation, simply align the first screw hole 151 with the second screw hole 112 and screw in the screw. Similarly, during disassembly, simply unscrew the screw, thus facilitating overall assembly and disassembly.

[0041] To facilitate the assembly and disassembly of the card plate 13, a through hole 152 is provided on the card slot block 15, and lugs 132 are provided at both ends of the card plate 13. The shape of the through hole 152 is adapted to the shape of the lugs 132. For example, the through hole 152 is set as a quadrilateral through hole 152, and correspondingly, the lugs 132 are also quadrilateral structures. When the lugs 132 are inserted into the through hole 152, the through hole 152 can limit the lugs 132 to prevent the support from shaking or rotating. Of course, in other embodiments, the through hole 152 can also be a polygonal structure, such as a triangular or pentagonal shape, etc., and is not limited here.

[0042] Since the lengths of different carrier rods 40 are different, the height of the card plate 13 needs to be adjusted. At least two through holes 152 are provided in the vertical direction of the card slot block 15. When the card plate 13 is inserted into different through holes 152, the height of the card plate 13 is also different. In this way, the card plate 13 has a higher adaptability to different carrier rods 40.

[0043] Specifically, the card plate 13 is a rectangular plate with slots 131 spaced along its long side. Lugs 132 are located on the short side of the card plate 13 and protrude outwards. The width of the slots 131 on the card plate 13 is determined by the structure of the tube-retrieving pen 30. Specifically, the tube-retrieving pen 30 has protrusions, and the width of the grooves 111 must be less than the width of the protrusions on the carrier rod 40. This ensures that the carrier rod 40 can be hooked onto the slots 131 of the card plate 13 and avoids falling off. The card plate 13 is inclined relative to the first support plate 11. This inclined arrangement acts as a hook. When the tube-retrieving pen 30, connected to the carrier rod 40, is hooked into the slots 131 of the card plate 13, its own weight prevents it from easily falling out of the slots. In this application, the angle between the card plate 13 and the horizontal plane is set to 35 degrees. After multiple tests, the effect of using a 35-degree angle is better. Of course, the angle between the card plate 13 and the horizontal plane can also be 40 degrees, 30 degrees, etc., that is, the angle between the card plate 13 and the horizontal plane is an acute angle.

[0044] In practical use, it should be noted that the structure of the freezer support rod 40 differs from that of the cryopreservation tube. The freezer support rod 40 has a handle that can be gripped, allowing the operator to operate it directly. When the freezer support rod 40 is used in conjunction with the cryopreservation auxiliary support 10, the height of the cryopreservation auxiliary support 10 and the width of the slot 131 of the card plate 13 need to be adjusted according to the product dimensions of the freezer support rod 40 to ensure that the protrusion of the freezer support rod 40 can be hooked onto the slot 131 of the card plate 13.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not 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 do 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.
