Embodiment 1

[0013] Example 1: When frozen embryos or oocytes 2 are frozen, it is necessary to use such figure 1 The elongated embryos shown are 2 tubes 1, figure 1 Among them, a is the seal, b is the 3.8cm of thawing solution, c is the air bubble of 0.3cm, d is the freezing solution of 0.6cm, e is the freezing solution with embryo or oocyte 2, and f is the tampon. The sequence of aspiration and aspiration is: b→c→d→c→e→embryo 2→e→c→d→c→b, then a and f. Each section needs to have precise length requirements to ensure the correctness of the operation and achieve the purpose of thawing and experimental results. The error in the operation process only based on the observation of the experimenter is too large, which will affect the viability of the embryo or oocyte 2, and even cause its death. It is also difficult to achieve an accuracy of 0.1 cm when temporarily measuring and marking the frozen thin tube 1 in time.

[0014] use as figure 2 The adjustable scale frame for the frozen thin t...

Embodiment 2

[0019] Embodiment 2: another kind of adjustable freezing thin tube 1 ruler frame, see Figure 5 , including a closed frame formed by connecting the two side walls, the bottom plate and the top plate in turn; the centers of the top plate and the bottom plate are respectively provided with an upper arc-shaped pressing piece 10 and a lower arc-shaped pressing piece matching the outer diameter of the frozen thin tube 1 11, and a scale 4 is provided on the upper arc pressing sheet 10 and / or the lower arc pressing sheet 11.

[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 ...

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 embryos, 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 embryos (embryos or oocytes) 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 a...
