Problems solved by technology

The blood after preservation and transportation cannot be tested for secondary quality indicators. The quality of the blood is mainly judged by naked eye observation experience, which lacks objective and effective basis.

Embodiment Construction

[0042] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] Aiming at the deficiencies in the prior art, the invention proposes a method for monitoring the shelf life of blood. This method first detects a series of empirical data of blood ATP content under different storage temperature conditions in the range of 4-32°C, and performs statistical processing on these data to fit the mathematical equation of blood quality with storage temperature and time, and uses microelectronics Technology has designed a miniature intelligent temperature-changing blood timer that can monitor blood storage temperature and storage time in real time, and then automatically calculate the remaining shelf life of blood (for example, converted to 4°C) according to the mathematical equation, which is used for blood storage and transportation. Monitoring of blood quality.

Abstract

The invention discloses a method for monitoring blood storage period which comprises steps of: providing a temperature variation blood timer connected with blood storage device; according to the variation of holding temperature and time, after statistics match to calculate the content of ATP in red blood cell; then evaluating the rest storage time of blood and displaying the rest storage time via the temperature variation blood timer. The inventive method has the advantages of being able to keep the temperature variation blood timer with blood, of being able to collect the temperature and cumulated storage time real-time.

Description

Technical field: [0001] The invention relates to blood preservation technology, in particular to a method for monitoring the shelf life of blood. The method calculates the remaining shelf life of the blood by using the mathematical equation that the ATP content in liquid blood changes with the storage temperature and storage time. Background technique: [0002] Blood transfusion is an important means of treating traumatic personnel, and the quality of blood is extremely critical to improving the success rate of treatment. Transfusion with expired preserved blood will not only fail to carry enough oxygen to the body, but will also cause complications such as hemolysis, inflammation, immune deficiency, and damage to multiple organs, which will affect the quality of treatment. At present, the most commonly used blood preservation method in the world is 4°C constant temperature preservation, and the shelf life of blood stored in different media is stipulated. Blood is a heat-se...
