Embodiment 1

[0014] use as figure 2 The adjustable scale frame for the frozen thin tube 1 is a frame structure that can wrap and fix the frozen thin tube 1 , and is provided with a corresponding scale 4 , which can be well combined with the frozen thin tube 1 . Not only can it conveniently provide a liquid absorption reference standard for the frozen thin tube 1, but also can improve the supporting strength of the frozen thin tube 1 itself to prevent shaking.

[0015] see figure 2 , image 3 and Figure 4 , Adjustable frozen thin tube 1 scale frame includes an open frame surrounded by two side walls, a bottom plate and a top plate, and a lock 7 that can be opened and closed is provided between the top plate and one of the side plates. It can be locked by pressing, and can be disassembled by breaking it by hand. The frozen capillary 1 is located therein, and positioning struts 8 can be respectively arranged between the two side walls in the frame 3 , and the inside of the positioning ...

Embodiment 2

[0020] The cryocapillary 1 can be inserted from one side by opening the top and bottom plates by applying pressure on both side walls inwardly.

[0021] At the same time, positioning struts 8 can also be respectively arranged between the two side walls in the frame. The upper and lower sides of the positioning struts 8 are not connected with the top plate and the bottom plate. Only the outer ends of the positioning struts 8 are connected with the corresponding side walls. The inside of the positioning brace 8 is provided with an arc-shaped edge matching the outer diameter of the frozen capillary 1 . An arc clip 9 is also arranged on the arc edge.

[0022] The top board or the bottom board can be made of transparent material, or the top board or the bottom board can be set as a transparent or non-transparent material with a hollow structure, and be provided with a frame 5 and a bead 6, and the bead 6 connects the frame 5 and the upper arc pressure sheet 10 or Lower arc pressur...

Abstract

The invention discloses an adjustable embryo freezing tubule scaleplate rack. The adjustable embryo freezing tubule scaleplate rack comprises an open type frame defined by two side walls, a bottom plate and a top plate, wherein an opening and closing controllable lock catch is arranged between the top plate and one side plate; an upper arc press sheet and a lower arc press sheet which are matched with the outer diameter of an embryo tubule are arranged in centers of the top plate and the bottom plate respectively; and the upper arc press sheet and / or the lower arc press sheet are / is provided with scaleplates. According to the invention, a frame structure for covering and fixing the embryo tubule is designed, and the corresponding scaleplates are arranged and can be combined with the embryo tubule well; not only can an imbibition reference standard be provided for the embryo tubule conveniently, but also the support strength of the embryo tubule can be improved, and shaking is prevented; the outer frame is light in weight, has certain hardness, can adopt transparent or hollow-out structure, and facilitates observation; and the adjustable embryo freezing tubule scaleplate rack is reasonable in structural design, good in use effect and suitable for popularization and application.

Description

technical field [0001] The invention relates to auxiliary tools in the technical field of animal husbandry and veterinary medicine, in particular to an adjustable ruler frame for embryo freezing thin tubes. Background technique [0002] In animal laboratories in the field of animal husbandry, it is often necessary to use frozen thin tubes to absorb embryos or oocytes to freeze or thaw animal embryos and oocytes. The operation process requires high precision. For example, in the process of vitrifying an embryo, the thin tube needs to absorb 3.8cm of thawing solution-0.3cm of isolation bubble-0.6cm of freezing solution-0.3cm of isolation bubble-a section of freezing solution with embryo (embryo or oocyte) Located in the center) - 0.3cm isolation bubble - 0.6cm freezing liquid - 0.3cm isolation bubble - 3.8cm thawing solution, seals and tampons are set at both ends. However, the frozen thin tube used in the laboratory is actually a simple and slender tube with a cotton plug at...
