Embodiment 1

[0024] refer to Figure 1-3 , a KM mouse embryo in vitro culture observation device, comprising an observation box 1, the observation mirror 2 is installed on the top of the observation box 1, the four corners of the bottom of the observation box 1 are welded with the first support rod 5, the first support rod 5 The top end is clamped with a fixed block 4, and the bottom end of the fixed block 4 is provided with a first slot 6 that matches the first support rod 5. The top of the fixed block 4 is welded with a placement plate 3, and the top of the placement plate 3 is evenly opened. There is a second card slot 7, the first card block 8 is connected to the inside of the second card slot 7, the top of the first card block 8 is bonded with a sterilizing protection pad 9, the observation box 1, the placement plate 3, the fixed block 4, The cooperative setting between the first support rod 5 and the first draw-in groove 6 can facilitate the removal of the placement plate 3, thereby ...

Embodiment 2

[0028] refer to Figure 1-3As another preferred embodiment of the present invention, the difference from Embodiment 1 is that the support mechanism includes first support legs 26 welded to the four corners of the bottom end of the viewing box 1, and shock absorbing springs are welded to the bottom ends of the first support legs 26 27. One end of the damping spring 27 is welded with a second support leg 29, and the bottom end of the second support leg 29 is welded with a universal wheel 30. A connecting mechanism is installed between the first support leg 26 and the second support leg 29, and the connection The mechanism includes a sleeve rod 28 slidably socketed under the first support leg 26. The middle part of the sleeve rod 28 is provided with a chute matching with the first support leg 26. The top end of the second support leg 29 is slidably connected to the sleeve rod 28. In the chute in the middle, the damping spring 27 between the first support leg 26 and the second sup...

Embodiment 3

[0030] refer to Figure 1-3 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that the fixing mechanism includes a fixing rod 31 symmetrically welded in the middle of the bottom end of the viewing box 1, and a second support rod is connected below the fixing rod 31 through a rotating mechanism 34. The rotating mechanism includes a rotating groove 32 provided below the fixed rod 31, a connecting shaft 33 is rotatably connected in the rotating groove 32, and a second supporting rod 34 is welded on one end of the connecting shaft 33, and the bottom end of the second supporting rod 34 is welded There is a friction plate 35, and the bottom end of the friction plate 35 is bonded with an anti-slip pad 36, and the cooperation between the fixed rod 31, the rotating groove 32, the connecting shaft 33, the second support rod 34 and the friction plate 35 is arranged to facilitate fixing the observation box 1. To avoid movement of the observati...

Abstract

The invention relates to the technical field of culture of KM mouse embryos, in particular to an observation device for culture in vitro of KM mouse embryos. The observation device comprises an observation box, wherein an observation mirror is mounted at the top end of the observation box, first support rods are welded to four corners of the bottom end of the observation box, a fixing block is inclamping connection to the top ends of the first support rods, a first clamping groove cooperating with the corresponding first support rod is formed in the bottom end of the fixing block, a placing plate is welded to the top end of the fixing block, second clamping grooves are uniformly formed in the top end of the placing plate, a first clamping block is in clamping connection to the inner partof the corresponding second clamping groove, a sterilizing protection pad is bounded to the top ends of the first clamping blocks, a switch gate is in hinged connection to the peripheral wall body ofthe observation box, above the placing plate, and a plurality of observation windows are mounted at the middle of the switch gate. According to the observation device, the placing plate can be convenient to disassemble, so that the placing plate can be conveniently cleaned; and observation windows and the observation mirror are arranged, so that comprehensive observation of the KM mice can be realized.

Description

technical field [0001] The invention relates to the technical field of KM mouse embryo culture, in particular to an observation device for KM mouse embryo culture in vitro. Background technique [0002] KM mice are the most outbred group of mice produced and used in my country. The gene pool is large and the gene heterozygosity rate is high. Chinese scholars have successively bred many inbred strains of mice from the outbred group of KM mice. After years of selective breeding, the tumor spontaneous rate in KM mice is extremely low. There are certain differences in the growth, development and reproductive performance of closed groups of Kunming mice raised in different places. But their common characteristics are strong disease resistance and adaptability, high reproduction rate and survival rate. [0003] The KM mouse embryo placement plate in the existing observation device for in vitro culture of KM mouse embryos is welded in the observation box, so it is inconvenient t...
