Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a blood preservation device. Background Art

[0002] Blood preservation generally refers to the storage of whole blood and red blood cell products. After medical staff draw blood from the patient, the blood sample is transported to the testing site. During the transportation process, in order to prevent the blood sample from rupturing and being affected by external temperature, which may cause blood denaturation, a blood preservation device is needed to preserve the blood sample.

[0003] According to the patent search, the announcement number is CN210556755U, which includes a preservation box, wherein the interior of the preservation box is evenly divided into two parts: a constant temperature chamber filled with constant temperature oil and a liquid nitrogen chamber filled with liquid nitrogen. The interiors of the constant temperature chamber and the liquid nitrogen chamber are fixedly connected with two slides that penetrate the front and rear ends of the chambers. The inner side of the slide is slidably connected with a placement box, and the inner side of the placement box is provided with a plurality of sample slots. In the utility model, the preservation box is composed of a constant temperature chamber and a liquid nitrogen chamber, and the heating rod heats the heating oil in the constant temperature chamber at a constant temperature, so that not only tumor blood samples but also other samples can be preserved. The constant temperature oil and liquid nitrogen are respectively wrapped around the outer periphery of the slide to ensure the uniformity of temperature. The temperature sensor processes the temperatures in the two chambers in real time through the AVR central control processor and displays them on the display screen, thereby improving the practicality and applicability of the preservation box.

[0004] The above patent can not only preserve tumor blood samples, but also other samples. However, it is difficult to know whether there is still space in the storage box for storing samples. If the storage box is directly opened to check or take out the stored samples, the temperature inside the storage box will be affected by the outside world, and temperature loss will occur, which may cause the blood samples to denature, thereby affecting the test results. Therefore, a blood preservation device is needed to solve the above technical problems. Utility Model Content
