Description

Cultivation temperature detector

Technical Field

The utility model relates to the technical field of constant-temperature cultivation, in particular to a cultivation temperature detector.

Background

In vitro fertilization refers to a technique in which the sperm and ovum of a mammal are subjected to fertilization in an in vitro artificial control environment, and is abbreviated as IVF. Since it is inseparable from embryo transfer technology (ET), it is also known as IVF-ET. In biology, animals obtained after transfer of an in vitro fertilized embryo to a mother are called test-tube animals (test-tube animals). With the development of scientific technology in recent years, the in vitro fertilization technology has important significance for animal reproductive mechanism research, livestock production, medicine, endangered animal protection and the like, and is becoming an important and conventional animal breeding biotechnology.

Whether an ovum, a sperm or an embryo is sensitive to temperature change, the embryo is at an optimum temperature and is close to the human body temperature; too low a temperature may lead to retarded embryo development; the spindle body of the embryo can be irreversibly damaged due to the overhigh temperature, the splitting and metabolism of the embryo are affected, the embryo can die during severe conditions, and for healthy growth of the embryo, the reproductive center generally operates at 37 ℃, so that the embryo needs to be cultivated at constant temperature, for example, chinese patent utility model patent No. CN204509275U discloses a novel test tube constant temperature device suitable for IVF laboratories, which comprises: a heat conductor, a large blind hole and a small blind hole; the heat conductor is cylindrical, and is provided with a large blind hole and a small blind hole. Said utility model only needs to place the heat conductor on the thermostatic board of the ultra-clean working table, when the temperature of the thermostatic board shows 37 deg.C, the test tubes containing ovum washing liquid and embryo transfer liquid can be placed in the big blind hole and small blind hole respectively, and because the depth and diameter of small blind hole are only 6.5cm and 1.5cm, it is simple and convenient when taking out, and the gap around blind hole and small test tube is small, so that it can obtain ideal constant-temp. effect. The cylindrical structure of the heat conductor occupies small area, saves space, does not need a power supply, and is convenient to use.

However, the above-mentioned thermostat only considers the test tube and heats, does not consider the temperature detection to the test-tube rack, and the change in space that the test-tube rack is located can lead to test tube temperature change, and the temperature change is too big and can lead to embryo development impaired, and the temperature detection to the test-tube rack is a thermometer of mostly simple insertion now, but the temperature of thermometer only can rise can not drop (mercury thermometer need throw and can descend), does not have a way to accurately detect the temperature that the cultivation test tube is located in real time.

Therefore, in order to solve the above problems, it is necessary to design a reasonably efficient incubation temperature detector.
