Description

Technical Field

[0001] The invention relates to the technical field of medical appliances, and in particular to a rotatable double-layer bracket for storing frozen embryos. Background Art

[0002] Embryo cryopreservation technology is very mature and widely used in human assisted reproductive technology. The controlled superovulation program of assisted reproductive technology often enables patients to obtain multiple embryos. After transplanting 1-2 embryos, the remaining embryos are often frozen and stored in a liquid nitrogen environment at -196°C. With the rapid growth of the number of patients in various reproductive centers, more and more embryos are stored in various reproductive centers, which brings greater storage space and cost pressure to the center. The embryos are frozen and stored on a carrier rod, which is then fixed on a freezing rack and frozen in liquid nitrogen. The freezing racks currently used on the market can only hold one layer of carriers. This form fails to fully utilize the space of the liquid nitrogen tank, and the number of frozen carriers that can be placed is small, resulting in low utilization of the liquid nitrogen tank. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a double-layer scaffold for storing frozen embryos, which is used to solve at least one of the above technical problems.

[0004] The technical solution of the present invention to solve the above technical problems is as follows:

[0005] A double-layer bracket for storing frozen embryos, comprising a first fixed slot structure, a second fixed slot structure, and a first fixed rod, a second fixed rod, and a third fixed rod arranged vertically, wherein the second fixed rod is coaxially arranged between the first fixed rod and the third fixed rod, and the two ends of the second fixed rod are respectively fixedly connected to the top end of the first fixed rod and the bottom end of the third fixed rod, the first fixed slot structure is spaced apart from the first fixed rod, a fixed block is arranged between the first fixed slot structure and the first fixed rod, and the fixed block is respectively fixedly connected to the bottom end of the first fixed rod and the bottom end of the first fixed slot structure;

[0006] The second fixed slot structure is spaced apart from the first fixed rod, a movable block is disposed between the second fixed slot structure and the first fixed rod, the movable block is sleeved on the rod body of the first fixed rod and forms a sliding connection with the first fixed rod that can slide up and down, and the side wall of the movable block is fixedly connected to the side wall of the second fixed slot structure;

[0007] The first fixed slot structure and the second fixed slot structure are both provided with sleeves on one side away from the first fixed rod, and the two sleeves are respectively clamped in the first fixed slot structure and the second fixed slot structure;

[0008] One end of the movable block that is slidably connected to the first fixed rod can slide onto the rod body of the second fixed rod to form a rotational connection;

[0009] A hook is provided at the top end of the third fixing rod, and the hook is fixed to the top end of the third fixing rod.

[0010] The beneficial effects of the present invention are as follows: the double-layer structure of the device can improve the space utilization rate in the liquid nitrogen tank, and the first fixed slot structure and the second fixed slot structure form an up-and-down relationship during freezing, and when it is necessary to take out the carrier rod in the sleeve of the first fixed slot structure, the second fixed slot structure is slid upward to the rod body of the second fixed rod and then slid downward after rotating 180°, so that the first fixed slot structure and the second fixed slot structure form a left-right relationship, which can facilitate the operator to take and place the frozen embryo carrier rod in the sleeve, and the operation is very simple.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows:

[0012] Furthermore, a support block is provided at the top of the first fixed slot structure.

[0013] The beneficial effect of adopting the above further solution is that the function of the support block is to provide support for the second fixed slot structure.

[0014] Furthermore, the outer surface of the hook is provided with identification positions for numbering and color differentiation.

[0015] The beneficial effect of adopting the above further solution is that the identification position makes it easier for management personnel to read the storage information in the bracket.

[0016] Furthermore, a gap is provided between the top end of the first fixing slot structure and the first fixing rod.

[0017] The beneficial effect of adopting the above further solution is that the role of the gap is to facilitate the movable block to slide freely to the bottom end of the first fixed rod.

[0018] Furthermore, the top end of the sleeve is provided with an opening.

[0019] The beneficial effect of adopting the above further solution is that the opening can facilitate users to take out the carrier rod placed in the sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

The length of the first fixed rod 1 is 18.5 cm, the length of the second fixed rod 7 is 4 cm, and the length of the third fixed rod 8 is 6.5 cm. The second fixed rod 7 is coaxially arranged between the first fixed rod 1 and the second fixed rod 8, and the two ends of the second fixed rod 7 are respectively fixedly connected to the top end of the first fixed rod 1 and the lower end of the third fixed rod 8. The axes of the first fixed rod 1, the second fixed rod 7 and the third fixed rod 8 are the same. The first fixed slot structure 2 is parallel to the first fixed rod 1 and is spaced apart. A fixed block 11 is arranged between the first fixed slot structure 2 and the first fixed rod 1, and the two ends of the fixed block 11 are respectively fixedly connected to the bottom end of the first fixed rod 1 and the bottom end of the first fixed slot structure 2;

[0027] A second fixed slot structure 3 is provided on the top of the first fixed slot structure 2, and the second fixed slot structure 3 is arranged parallel to the first fixed rod 1 and spaced apart. A movable block 4 is provided between the second fixed slot structure 3 and the first fixed rod 1, and one end of the movable block 4 is provided with a through hole that runs through the first and second fixed rods 1 and has the same shape as the outer wall of the first fixed rod 1. One end of the movable block 4 is sleeved on the rod body of the first fixed rod 1 through the through hole and forms a sliding connection with the first fixed rod 1 that can slide up and down, and the inner wall of the through hole is circumferentially slidably connected to the outer wall of the rod body of the first fixed rod 1, and the other end of the movable block 4 is connected to the second fixed slot structure 3 and the first fixed rod 1. The side walls of the two fixed slot structures 3 are fixedly connected; a support block 6 is provided between the top end of the first fixed slot structure 2 and the bottom end of the second fixed slot structure 3, and the support block 6 is fixed to the top end of the first fixed slot structure 2 and abuts against the bottom end of the second fixed slot structure 3; a gap is provided between the top end of the first fixed slot structure 2 and the first fixed rod 1 to facilitate the movement of the movable block 4, and the movable block 4 first slides upward from the first fixed rod 1, slides onto the second fixed rod 7, and then rotates 180°, and then slides downward to the bottom end of the first fixed rod 1 and its bottom end abuts against the top end of the fixed block 11.

[0028] The first fixed slot structure 2 and the second fixed slot structure 3 are both provided with a sleeve 5 with an opening at the top end on the side away from the first fixed rod 1, and the two sleeves 5 are respectively clamped in the first fixed slot structure 2 and the second fixed slot structure 3; the length of the sleeve 5 is 11.5 cm, and the length of the first fixed slot structure is slightly larger than the length of the sleeve; the first fixed slot structure 2 includes a semicircular groove with an opening away from the first fixed rod 7 and fixed wings respectively arranged on both sides of the opening of the semicircular groove, the two fixed wings and the semicircular groove enclose a vertical cylindrical space for clamping the sleeve 5, and the fixed wings have a certain elasticity. When the sleeve 5 is clamped, the bottom end of the sleeve 5 is inserted into the cylindrical space through the gap above the fixed wings.

[0029] The circular diameter of the second fixing rod 7 with a circular cross-section is consistent with the width of the first fixing rod 1 with a rounded rectangular cross-section.
