Description
Technical field
The application is related to a kind of heat sink, is filled more particularly to a kind of cooling used during stem cell cryopreserving
Put, more particularly to one kind is stem cell is cooled by predetermined way and in this temperature-fall period during stem cell cryopreserving
In facilitate stem cell to be mixed with frozen stock solution, a kind of such as heat sink of hand mix.During the stem cell cryopreserving of the application
Disposal of the heat sink used particularly suitable for stem cell during freezing.
Background technology
Generally, stem cell makes stem cell be mixed with frozen stock solution, it is necessary to add frozen stock solution after collection, processing
It is even, then preserved at a temperature of being placed into ultralow temperature such as -80 DEG C of even lower -196 DEG C.And stem cell is cold from room temperature
But into the temperature course of this ultralow temperature, it is necessary to slowly cool during carry out mixed processing, make stem cell and frozen stock solution
It is well mixed while cooling.
Stem cell sample is adding frozen stock solution during this at present, substantially using traditional ice bag parcel centrifuge tube
(or directly centrifuge tube being put into the box equipped with isopropanol, body directly contacts with isopropanol), so as to indirectly to sample
This progress precooling while the holding sample relative low temperature during sample adds frozen stock solution；Exist in above procedure ice bag to from
Heart pipe parcel is not bonded and ice bag heating is very fast (isopropanol easily splashes, and causes the pollution of environment or sample), and is not easy to carry out
One hand mixes operation.
Prior art not publicly can solve the problem that the method or scheme of above-mentioned technical problem.Freeze in spite of some other stem cell
The middle device used is deposited, but they are not all suitable for the above-mentioned application field of the application, solve above-mentioned technical difficulty.For example, CN
205124851U (201520942099.7) discloses a kind of cell freezing storage device, including freezes ice chest body, freezes ice chest body and adopts
With sealing structure, the inner homogeneous for freezing ice chest body is provided with carrier ring, and hollow part is provided with cell between adjacent separator layer
Accommodating area, each cell accommodating area are mounted on the cabinet door being flexibly opened and closed, temperature controller, temperature control are provided with below cell accommodating area
Device connects control panel by temperature sensor, and control panel is internally provided with electric-controlled plate linking refrigerator, the outlet of refrigerator
Hollow region in mouth linking freezer box, is freezed, each cell accommodating area so that cell is placed in casing at any time
A corresponding cabinet door, do not influence the temperature of other cells when placing, make stem cell can be with uniform decrease in temperature, it is believed that square law device is grasped
Make simple, time-consuming shorter, it is ensured that the activity of cell, the demand of social development is adapted to, it is novel in design, it is a kind of innovation well
Scheme, there is very much market promotion prospect.However, regrettably, these above-mentioned designs not can effectively solve the problem that this Shen
Please above-mentioned the problem of referring to.
Therefore, this area is still expected to have new design to solve the above-mentioned technical problem run into of the application, especially
Be that by stem cell realized in freezing temperature-fall period it is convenient in cooling while the requirement of sample treatment that mixes, such as gram
Take the sample temperature that stem cell sample occurs in frozen stock solution this link is added easily rise, heat sink to centrifuge tube (or
Other carriers) inclusion has infelicity, and one hand, which is not allowed to be easy to do, mixes the technical barrier of operation.
