An automatic lifting ice bath test tube rack control system and its realization method

Abstract

The invention discloses an automatic lifting ice-bath test tube rack control system and its realization method. The water storage tank is equipped with a refrigeration device and a heating device, an RFID chip reader is provided on the inner wall of the test tube grid, a gravity sensor is provided at the opening of the test tube grid, the output terminal of the RFID chip reader and the gravity sensor The output terminals are all connected to the input terminals of the signal processing system, the output terminals of the signal processing system are respectively connected to the input terminals of the refrigeration device, the input terminal of the heating device, the input terminal of the telescopic device and the input terminal of the pump, and the power supply is respectively connected to the refrigeration device, heating device, telescoping device, signal processing system, water pump, RFID chip reader and gravity sensor. The invention realizes the information checking function, has low cost and high practicability, and can be widely used in the technical field of sample collection equipment.

Description

technical field [0001] The invention relates to the technical field of sample collection equipment, in particular to an automatic lifting ice bath test tube rack control system and its implementation method. Background technique [0002] In the phase I drug clinical trial with human as the object, the concentration of the drug or its metabolites in the blood is analyzed by collecting the blood samples of the subjects at different time points, and a complete blood drug concentration-time curve is formed, which reflects the effect of the drug on the human body. The dynamic changes of absorption, distribution, metabolism and excretion in the body. Therefore, the management of biological samples is the core content of clinical trials. Generally, the sampling points of phase I clinical trials include the absorption phase, near peak concentration and elimination phase after administration. Generally, there are no less than 11 to 12 sampling points and the number of people in each...

Problems solved by technology

[0003] At present, the commonly used test tube racks are designed in one piece, and the distance between the test tubes is small, which is inconvenient for information checking; moreover, when collecting multiple blood samples from multiple patients, it is necessary to place the blood sample test tubes on the plastic or stainless steel test tube racks Take out one by one, it is easy to take the wrong test tubes, which will affect the test results; in addition, because the collected blood samples generally need to be stored in a low temperature environment, and the test needs to be properly heated and thawed, the existing test tube racks are generally stored in the freezer Zhonglai achieves low-temperature storage, and then takes it out of the freezer in advance to thaw at room temperature during testing. This storage method is based on a high-quality freezer, which requires a large purchase cost, and the thawing speed at room temperature is slow, which is not practical enough.
