Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a novel plug-in constant temperature PCR ice box. Background Art

[0002] PCR, the Chinese name is polymerase chain reaction. PCR technology is a common method for in vitro enzymatic synthesis of specific DNA fragments. Since PCR reagents are very sensitive to temperature, when conducting PCR experiments at room temperature, primers will react under the action of enzymes, resulting in mismatches and producing erroneous PCR products, affecting the experimental results. Therefore, when conducting PCR experiments, PCR reagents and PCR tubes are often placed on an ice box for operation. At this time, the reaction activity of the enzyme will be reduced, thereby reducing nonspecific amplification and improving the accuracy of the results.

[0003] The commonly used PCR ice box is used after being frozen in the refrigerator for a period of time. During use, since the PCR reaction system is generally only a few dozen microliters, sometimes the ice box is too cold and will soon freeze, and it cannot maintain a constant temperature (or maintains a very short time), and it cannot display the temperature in real time, making it difficult to make relatively accurate control of the temperature during use.

[0004] In the prior art, Chinese patent CN202766523UPCR low temperature special sample loading ice box discloses a low temperature special sample loading ice box, which includes a tray and a protective cover used in conjunction with the tray, the tray top slot is connected to a loading rack, the loading rack is provided with a horizontal plate at the lower end, the horizontal plate is circumferentially fixed to the inner wall of the tray to form a closed chamber, and the closed chamber is filled with refrigerant. The utility model is set as a fixed and sealed ice box, which has the advantages of convenience in carrying, using and managing; secondly, a horizontal plate with a U-shaped groove is set in the tray, so that the PCR tube is in a low temperature state during the loading process, and at the same time, the phenomenon of water vapor condensation is avoided, ensuring the accuracy of the test results; thirdly, the support plate added in the tray further improves the firmness of the tray and extends the service life.

[0005] Chinese patent CN201361554Y water bath ice box for loading large-capacity PCR tubes discloses a water bath ice box for loading large-capacity PCR tubes, providing a water bath ice box for loading large-capacity PCR tubes that can load multiple PCR tubes at one time, ensure that the PCR system is immersed in a 0°C water bath, and ensure that the PCR system is always at a temperature of 0°C before being placed in a PCR instrument.

[0006] Chinese patent CN 219301080 U Ice-making structure and refrigerator discloses an ice-making structure and refrigerator, wherein the ice-making structure includes: an ice box for containing liquid and ice cubes converted from liquid; an ice-making evaporating pipe, the ice-making evaporating pipe includes: two parallel straight segments and a bending section connecting the two straight segments; wherein two mounting grooves are provided on the side of the ice box corresponding to the two straight segments; the bending section is inclined in a direction away from the ice box so that the ice-making evaporating pipe can be slidably assembled in the two mounting grooves. The bending section avoids the protruding part of the ice box so that the ice-making evaporating pipe will not interfere with the protruding part of the ice box during the sliding process, thereby ensuring a smooth assembly process, and after the assembly is completed, the ice-making evaporating pipe directly acts on the ice box to cool the ice box, the contact thermal resistance is small, and the heat transfer speed between the ice-making evaporating pipe and the ice box can be accelerated, thereby accelerating the ice-making efficiency, reducing the waiting time of users, and improving the user experience.

[0007] Some improvements have been made in the prior art to make the PCR ice box more convenient and durable. The existing PCR ice box cannot accurately control the temperature, and needs to wait during use, which affects the user's work efficiency and reliability during use. The utility model has multiple functions such as accurate temperature control and scheduled refrigeration, which is very practical and convenient. When the user uses it, the operation is convenient, the temperature control is long-lasting and constant, and the function of scheduled refrigeration can be realized. Utility Model Content
