Automatic placenta stem cell taking and storing device preventing hands of people from being frozen

Abstract

The invention discloses an automatic placenta stem cell taking and storing device preventing the hands of people from being frozen. The automatic placenta stem cell taking and storing device comprisesa bottom plate. A supporting plate and a storing pot are arranged on the surface of the bottom plate. A sliding groove is formed in the supporting plate. A sliding block is connected into the slidinggroove in a sliding manner. The top end of the sliding block is connected with the supporting plate through a first electric telescoping rod. The sliding block is connected with a first connecting block through a second electric telescoping rod. The first connecting block is connected with a connecting plate through a third electric telescoping rod. The connecting plate is connected with an installing plate through a connecting column. According to the automatic placenta stem cell taking and storing device preventing the hands of people from being frozen, a control switch is used for controlling work of all the electric telescoping rods, thus, taking and storing work can be carried out, operation and use of users are facilitated, the users only need to open or close a sealing cover, thus,the working difficulty of the users is reduced, and the users can be effectively prevented from being frozen.

Description

technical field [0001] The invention relates to the technical field of stem cell access, in particular to an automatic access device for placental stem cells that prevents frostbite of human hands. Background technique [0002] Liquid nitrogen freezing tank is the main product type of liquid nitrogen biological container, which includes a tank body with a tray, a freezer shelf on the tray, a freezer box placed on the freezer shelf, and a biological freezer box placed in the freezer box. Tissues and other objects that need to be frozen, the liquid nitrogen in the tank provides a low-temperature environment for the objects to be frozen, and the packaged biological tissues placed on the tray are placed in an environment of more than minus 100 degrees Celsius, which can achieve long-term freshness. Purpose: In order to facilitate access to the cryopreservation box, the upper end of the liquid nitrogen cryopreservation tank is provided with a cover, and a cover plate is provided ...

[0002] Liquid nitrogen freezing tank is the main product type of liquid nitrogen biological container, which includes a tank body with a tray, a freezer shelf on the tray, a freezer box placed on the freezer shelf, and a biological freezer box placed in the freezer box. Tissues and other objects that need to be frozen, the liquid nitrogen in the tank provides a low-temperature environment for the objects to be frozen, and the packaged biological tissues placed on the tray are placed in an environment of more than minus 100 degrees Celsius, which can achieve long-term freshness. Purpose: In order to facilitate access to the cryopreservation box, the upper end of the liquid nitrogen cryopreservation tank is provided with a cover, and a cover plate is provided at a non-central position on the cover. The purpose of taking out the freezer boxes is that with the increase in the demand for refrigeration, the required liquid nitrogen freezer tanks are getting bigger and bigger, and the access to the freezer boxes has become a time-consuming and laborious task. Poor coordination between the holding tools and other links will also lead to the loss of a large amount of cooling capacity in the tank. In addition, the extremely low temperature of liquid nitrogen may cause bodily harm to the operator
