Embodiment

[0031] Please refer to Figure 1 to Figure 4 , the present embodiment provides an auxiliary activation device 100 for frozen embryos 200 (hereinafter referred to as the auxiliary activation device 100), which includes a housing 10 with an accommodating cavity 20 inside, and the frozen embryos 200 accommodated in the straw are arranged in the accommodating cavity 20 Inside, a light source 30 is provided on the inner wall of the casing 10 , and the light source 30 emits low-intensity light to the frozen embryo 200 . The auxiliary activation device 100 for the frozen embryo 200 can be used as an auxiliary activation means for the frozen embryo 200 to improve the survival rate of the frozen embryo 200 recovery, thereby increasing the clinical pregnancy rate of the frozen embryo 200 recovery.

[0032] It should be noted that therapeutic light sources (including lasers and LEDs, etc.) used in medicine can generally be divided into two categories: weak light and strong light. Becaus...

Abstract

The invention discloses an auxiliary activation device for a frozen embryo, and relates to the technical field of medical equipment. The device comprises a shell internally provided with a containingcavity; the frozen embryo contained in a straw is arranged in the containing cavity; a light source is arranged on the inner wall surface of the shell; and the light source emits low-intensity light to the frozen embryo. The auxiliary activation device for the frozen embryo can be used as an auxiliary activation means for the frozen embryo, the survival rate of frozen embryo recovery is increased,and therefore the clinical pregnancy rate of frozen embryo recovery is increased.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an auxiliary activation device for frozen embryos. Background technique [0002] Embryo freezing is to put the embryos and freezing liquid into a straw, and through slow (2-3 day embryos) and fast (5-6 day blastocyst) cooling methods, the embryos can be stilled and stored A method of preservation in a liquid nitrogen environment at minus 196°C, and implanted into the uterine cavity after thawing in a natural cycle or an artificial cycle will increase the chance of conception. It is the only mature method to preserve reproductive function so far. [0003] Although embryos can be dormant for a long time in an ultra-low temperature environment, the recovery and thawing activation process of frozen embryos often needs to be carried out quickly in order to improve the survival rate of frozen embryo recovery. In the prior art, the thawing of the embryo adopts the quick thawi...
