[0002] Currently, in the embryo freezing process in the field of assisted reproduction, vitrified cryopreservation carriers are generally used. The embryo is placed on the surface of the cryopreservation carrier, and then the cryopreservation carrier is loaded into an outer tube in liquid nitrogen. During the installation of the outer tube, the influence of liquid nitrogen vapor makes the installation inconvenient for operators, resulting in a long installation time between the cryopreservation carrier and the outer tube, thereby reducing the safety factor of embryo preservation. Utility Model Content

[0016] 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.

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the structure, this utility model embodiment provides an installation aid for embryo cryopreservation carriers. The installation aid includes a funnel-shaped aid body 1 and a connecting portion 2. The aid body 1 has a guide end 11 with a larger diameter and a connecting end 12 with a smaller diameter. The guide end 11 is the inlet, with a larger diameter to facilitate the entry of embryo cryopreservation carriers such as cryopreservation rods. A conical surface exists between the guide end 11 and the connecting end 12. The connecting end 12 is used for fixed connection with the connecting portion 2. The connecting portion 2 is fixedly connected to the connecting end 12 for detachable installation. The auxiliary device is fitted onto the open end of the outer sleeve 3; the auxiliary device can be installed on the outer sleeve 3 through the connecting part 2, realizing the assembly of the auxiliary device and the outer sleeve 3; the auxiliary device body 1 is composed of a conical cylinder; the end face shape of the connecting end 12 and the guide end 11 is annular, the inner diameter of the connecting end 12 is equal to the inner diameter of the outer sleeve 3, and the inner diameter of the guide end 11 is larger than the inner diameter of the connecting end 12. The inner diameter of the guide end 11 is 1.5-3 times the inner diameter of the connecting end 12, preferably 2 times the inner diameter of the connecting end 12.

[0018] In the aforementioned installation aid, the connecting part 2 can be composed of a sleeve or a half-ring. For example... Figure 1 and Figure 2 As shown, when the connecting part 2 is composed of a sleeve, the inner diameter of the sleeve is equal to the outer diameter of the outer sleeve 3. The sleeve and the outer sleeve 3 can be fitted with a clearance fit, allowing the sleeve to be assembled smoothly while also achieving a tight fit between the sleeve and the outer sleeve 3. The sleeve and the outer sleeve 3 are fixed together by magnetic adsorption. The open ends of both the sleeve and the outer sleeve 3 contain magnetic material; when the sleeve is fitted onto the open end of the outer sleeve 3, the magnetic force generated by the magnetic material causes the outer sleeve 3 to be attracted to the sleeve.

[0019] like Figure 3 and Figure 4 As shown, when the connecting part 2 is composed of a semi-ring, the inner diameter of the semi-ring is equal to the outer diameter of the outer sleeve 3, allowing the semi-ring to fit tightly onto the outer wall of the outer sleeve 3. The semi-ring and the outer sleeve 3 are fixedly connected by magnetic adsorption. Both the open ends of the semi-ring and the outer sleeve 3 contain magnetic material; when the semi-ring is fitted onto the open end of the outer sleeve 3, the magnetic force generated by the magnetic material causes the outer sleeve 3 and the semi-ring to adhere and be fixed together.

[0020] The working principle of the aforementioned installation aid is as follows: both the installation aid and the open end of the outer tube 3 are infused with magnetic material, allowing them to connect magnetically. With the aid of the installation aid, even in the presence of liquid nitrogen vapor, embryo technicians can easily insert the carrier into the outer tube 3. The magnetic material design also facilitates the removal of the installation aid, enabling embryo preservation and the reuse of the installation aid.

[0021] The above-mentioned installation aid is connected as follows: the installation aid is connected to the magnetic end of the outer tube 3, placed in liquid nitrogen, and the cryogenic carrier containing the embryo is installed into the outer tube 3 with the help of the installation aid. After that, the installation aid is removed. The installation aid can be reused.

[0022] When used as an embryo cryopreservation carrier, the aforementioned installation aid allows for easy insertion into the outer sheath 3 via the connecting part 2, shortening installation time. The larger diameter guide end 11 facilitates insertion of the cryopreservation rod into the aid body 1. The funnel-shaped aid body 1 guides the cryopreservation rod, enabling the embryo cryopreservation carrier, including the cryopreservation rod, to quickly enter the outer sheath 3. This also reduces unintentional scratches by laboratory personnel during loading, thereby improving the safety of embryo preservation. Furthermore, the installation aid and outer sheath 3 are connected via magnetic adsorption, making the connection convenient, quick, and reliable. The semi-ring design of the connecting part 2 further facilitates assembly, allowing the installation aid to be installed and removed from one side of the outer sheath 3, making assembly and disassembly simpler and more convenient. Therefore, using the aforementioned installation aid facilitates the loading of embryo cryopreservation carriers into the outer sheath 3, is easy to install and remove, shortens installation time, and thus allows for safer, more convenient, and faster embryo loading.

[0023] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this utility model without departing from the spirit and scope of this utility model. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
