Abstract

The invention discloses an enclosed vitrified refrigerating carrier which comprises a carrier inner core, a sleeve and a sleeve adapter unit, wherein the carrier inner core comprises a pipe cap, a carrier rod and a sample storage area which are mold integrally and communicated with one another; the sleeve comprises an inner sleeve and an outer sleeve; the inner sleeve is of a pipe structure of which the upper end is provided with an opening; an air hole is formed in the outer sleeve; the upper end of the sleeve adapter unit is in sealed connection with the lower end of the pipe cap by adoptinga breakable connecting manner; the inner sleeve is arranged on the carrier rod in a sleeving manner; the lower end of the sleeve adapter unit is in sealed connection with the inner sleeve; and the outer sleeve is arranged outside the inner sleeve. According to the enclosed vitrified refrigerating carrier disclosed by the invention, the sample is sealed by the inner sleeve and avoided from contacting with liquid nitrogen; the air hole is formed in the outer sleeve, the liquid nitrogen can enter the outer sleeve, the own buoyancy of the refrigerating carrier is balanced, the liquid nitrogen stored in the outer sleeve can maintain at a low temperature in a short time when the liquid nitrogen is isolated, and liquid nitrogen vapor can be rapidly discharged by the air hole; and the height of the outer sleeve is moderate, locating recognition can be realized, and high space utilization rate is reached.

Description

technical field [0001] The invention relates to the field of carriers for biological material cryopreservation, in particular to a closed vitrification carrier. Background technique [0002] At present, the carriers used for vitrification storage of embryos, gametes (eggs, sperm) and ovarian tissues in the biological and medical fields mainly include three categories: frozen rings, frozen straws and frozen straws. [0003] In the use of freezing rings, there are high technical requirements for sample ring installation, and strict training and skilled operators are required to successfully complete the operation. And because the freezing ring is made of plastic and the loading rod is made of metal, a certain gap is formed between the two, causing liquid nitrogen to remain in the gap. During the melting process, a large number of bubbles or bursts will appear when the liquid nitrogen volatilizes, resulting in the loss of samples. [0004] Frozen straws and frozen loading rod...
