Constant-temperature test tube rack for reproductive department

Abstract

The utility model provides a constant-temperature test tube rack for the reproductive department, and belongs to the technical field of medical instruments. The heat conduction layer is heated through the heating device, and then the heat conduction layer transmits heat energy to the water bath kettle, so that the heat preservation inner shell in the filter screen shell in the water bath kettle and a test tube in the heat preservation inner shell are uniformly heated, and meanwhile, the temperature around the test tube can be more accurately controlled; the defects that a temperature sensor can only sense local water temperature, and a constant temperature controller has large deviation when controlling the water temperature are effectively relieved. Temperature is transmitted to the single-chip microcomputer through signals of the temperature sensor, and the single-chip microcomputer controls a switch of the heating device, so that the water temperature near the heat preservation inner shell in the water bath kettle is kept close to the human body temperature.

Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a constant temperature test tube rack for reproductive medicine. Background Art

[0002] At present, during the egg retrieval process, the doctor uses an egg retrieval needle to retrieve the eggs, and sucks the follicular fluid into the test tube by negative pressure suction. Then the test tube with follicular fluid is placed on the test tube rack for storage.

[0003] During the follicular fluid extraction process, the nurse holds the test tube by hand. When the follicular fluid is collected by 2 / 3 of the test tube, a new test tube is replaced and the test tube with follicular fluid is placed on the constant temperature test tube rack in the laboratory. However, after the follicular fluid is taken out from the body, the nurse's hand-holding method cannot maintain the constant temperature of the follicular fluid in the test tube, resulting in the temperature of the extracted follicular fluid being instantly lower than the human body temperature. The large temperature difference affects the quality of the egg or the survival rate of the egg, thereby reducing the success rate of test-tube babies. In addition, although the constant temperature test tube rack under the existing technology is provided with a temperature monitoring device, there is a problem that the temperature monitoring device can only sense the local temperature, and a large temperature difference will occur near the test tube when implementing constant temperature control.
