[0046] As Figures 3-12 As shown in the figure, the utility model provides a kind of for storing embryo cryopreservation carrier's outer cannula, including sleeve main body 100 and limit sleeve 300.

[0047] Wherein, sleeve main body 100 includes first pipe body 110 and second pipe body 120.

[0048] The first tube 110 is used to store the embryo cryopreservation carrier 600. The first tube 110 is hollow and has an open first end. The second tube 120 is hollow and has an open first end. The limiting sleeve 300 is hollow and has an open first end, and the limiting sleeve 300 is disposed inside the second tube 120.

[0049] The first end of the first tube 110 and the first end of the second tube 120 are hinged together. An operating port 102 is provided on the side wall of the second end of the second tube 120. The limiting sleeve 300 has a first position and a second position that can be switched between each other. When the limiting sleeve 300 is in the first position, it is located inside the second tube 120, allowing the first tube 110 and the second tube 120 to rotate around the hinge center line. When the limiting sleeve 300 is in the second position, its first end extends into the first tube 110, preventing the first tube 110 and the second tube 120 from rotating. Simultaneously, the limiting sleeve 300 also seals the clearance notch 103. Specifically, when the limiting sleeve 300 is in the second position, the cooperation between the limiting sleeve and the first tube 110 and the second tube 120 prevents them from rotating relative to each other.

[0050] Specifically, during use, when it is necessary to place or remove the embryo freezing carrier 600, firstly, the limiting sleeve 300 is placed in the first position; then, a torque is applied to the first tube 110 or the second tube 120 to make the first tube 110 or the second tube 120 rotate relative to the hinge center line, thereby making the first tube 110 and the second tube 120 offset from each other; then, the embryo freezing carrier 600 is taken out from the first tube 110 or placed in the first tube 110; finally, the limiting sleeve 300 is moved to the second position, thereby preventing the first tube 110 and the second tube 120 from rotating relative to each other.

[0051] In this embodiment, the outer tube for storing the embryo cryopreservation carrier rod can be rotated to make the first tube 110 and the second tube 120 misaligned when the embryo cryopreservation carrier rod 600 is placed or removed. This facilitates placing the embryo cryopreservation carrier rod 600 in the first tube 110 and removing the embryo cryopreservation carrier rod 600 from the first tube 110.

[0052] like Figure 5 , 6 As shown in Figures 10 and 11, in this embodiment, a first hinge portion 111 is provided on the first side of the first end of the first tube 110, and a second hinge portion 121 is provided on the first side of the first end of the second tube 120. The first tube 110 and the second tube 120 are hinged together by the first hinge portion 111 and the second hinge portion 121.

[0053] As shown in Figure 6 , 11 , the first hinge part 111 is provided with a first insertion hole, and the second hinge part 121 is correspondingly provided with a second insertion hole, and a hinge shaft 400 is inserted in the first insertion hole and the second insertion hole.

[0054] Preferably, in a natural state, the first pipe body 110 and the second pipe body 120 can be kept at any position, and when the torque applied on the first pipe body 110 or the second pipe body 120 exceeds a preset value, the first pipe body 110 and the second pipe body 120 can rotate around the hinge center line thereof. That is, the hinge shaft 400 and the first insertion hole and the second insertion hole are in interference fit. In the process of taking and placing the embryo freezing carrier 600, the first pipe body 110 and the second pipe body 120 can be kept at any position and will not swing at will, so as to achieve the purpose of facilitating taking and placing the embryo freezing carrier 600.

[0055] As shown in Figure 3 , 4 , 7, 8, 9, 12, the limiting sleeve 300 is in sliding connection with the second pipe body 120, so that the limiting sleeve 300 can reciprocate between the first position and the second position.

[0056] Preferably, in a natural state, the limiting sleeve 300 can be kept at any position in the second pipe body 120, and when the external force applied on the limiting sleeve 300 exceeds a preset value, the limiting sleeve 300 can move in the second pipe body 120. That is, the limiting sleeve 300 and the second pipe body 120 are in interference fit, so that the limiting sleeve 300 will not move at will, thereby achieving the purpose of facilitating taking and placing the embryo freezing carrier 600.

[0057] As shown in Figures 3-12 , the second side of the first end of the second pipe body 120 is provided with an avoiding gap 103, so that when the embryo freezing carrier 600 is placed in the first pipe body 110, the embryo freezing carrier 600 can partially extend into the second pipe body 120. When the embryo freezing carrier 600 is taken and placed, the embryo freezing carrier 600 partially extends out of the first pipe body 110, thereby achieving the purpose of facilitating taking and placing the embryo freezing carrier 600.

[0058] As shown in Figure 5 , 6As shown in Figures 10 and 11, the inner wall of the first tube 110 is provided with a limiting member 500 to limit the limiting sleeve 300. The limiting member 500 is provided with a limiting hole 510 for limiting the end of the embryo freezing carrier rod 600 facing the second tube 120. When the embryo freezing carrier rod 600 is placed inside the first tube 110, the embryo freezing carrier rod 600 is inserted into the limiting hole 510. Under the action of the limiting member 500, the end of the embryo freezing carrier rod 600 facing the second tube 120 will not come into contact with the inner wall of the first tube 110 or the second tube 120, and thus will not affect the movement of the limiting sleeve 300 from the first position to the second position. At the same time, during the process of moving the limiting sleeve 300 from the first position to the second position, under the action of the limiting member 500, when the limiting sleeve 300 moves to the second position, the limiting sleeve 300 can no longer continue to move away from the first position, thereby achieving the purpose of limiting the limiting sleeve 300.

[0059] like Figure 5 , 6 As shown, multiple limiting holes 510 are provided, and the inner diameter of the limiting holes 510 is adapted to the outer diameter of the embryo freezing carrier 600. Specifically, the inner diameter of the limiting holes 510 is slightly larger than the outer diameter of the embryo freezing carrier 600, so as to better limit the embryo freezing carrier 600. When the embryo freezing carrier 600 is inserted into the first tube 110, the embryo freezing carrier 600 is located in the limiting holes, so that the embryo freezing carrier 600 can be placed orderly in the first tube 110 without tilting or contacting the inner wall of the first tube 110 or the second tube 120.

[0060] Preferably, the end of the limiting hole facing the second tube 120 is open and funnel-shaped, so that the embryo freezing carrier rod 600 can be inserted into the limiting hole.

[0061] like Figure 3 , 4 As shown in Figures 5, 7, 8, 9, 10, and 12, an operating part 310 is provided at the second end of the limiting sleeve 300 to facilitate movement of the limiting sleeve 300. The operating part 310 can be located on the side wall of the second end of the limiting sleeve 300 or on the end side wall of the second end of the limiting sleeve 300. Furthermore, there are no restrictions on the shape of the operating part 310.

[0062] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0063] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
