Abstract

The invention relates to a sperm freezing device which comprises a tank body, a liquid level adjusting mechanism, a bracket, a timer and a controller, wherein an accommodation cavity is formed in thetank body; the accommodation cavity is internally provided with a partition plate for partitioning the accommodation cavity into a standby storage cavity and a freezing cavity; the inner wall of the freezing cavity is provided with a first position and a second position at an interval; the liquid level adjusting mechanism is mounted on the partition plate and is used for communicating the standbystorage cavity with the freezing cavity when the liquid level in the freezing cavity is lower than a preset value, and thus the liquid level in the freezing cavity is kept constant; the bracket is mounted on the inner wall of the freezing cavity in a sliding manner along a connection line direction of the first position and the second position; the bracket is used for holding sample cryopreservation tubes with sperm samples; the timer is used for setting fumigation time according to preset instructions; and the controller is electrically connected with the timer, and is used for controlling the bracket to move to the second position from the first position when the timer meets the fumigation time. Therefore, due to adoption of the sperm freezing device, the quality of frozen sperms is high.

Description

technical field [0001] The invention relates to the technical field of sperm freezing, in particular to a sperm freezing device. Background technique [0002] Sperm freezing is a technique for men to freeze their own sperm in medical institutions with corresponding qualifications in consideration of their future fertility plans to prevent future fertility risks. It can be used as an assisted reproductive method for infertile people. Some very For patients with severe oligospermia, precious sperm can be frozen during treatment to prevent azoospermia from developing in the future. [0003] The rare sperm is usually frozen by vitrification. Before the cryopreservation tube containing the sperm sample is put into liquid nitrogen for freezing, it needs to be placed above the liquid nitrogen liquid level for fumigation for a period of time. Moreover, in the sperm fumigation process, in order to ensure the quality of the sperm, it is necessary to strictly control the fumigation ti...
