Method and equipment for separating serum

Abstract

The invention relates to a method for separating serum. The method comprises the following steps of: 1, providing blood collection tubes in which blood specimens are arranged, and heating the blood specimens in the blood collection tubes by using a constant temperature gas bath to make the temperatures of the blood specimens reach 37 DEG C; 2, grabbing the blood collection tubes by using mechanical hands; 3, automatically measuring the weight of the blood collection tubes, and recording the weight; 4, comparing the total weight of centrifugal canisters which are provided with the blood collection tubes and are symmetrically arranged on both sides, and placing the blood collection tubes on the lighter centrifugal canister; 5, calculating the total weight of the centrifugal canisters which are provided with the blood collection tubes; 6, placing the blood collection tubes into the two symmetric centrifugal canisters, and then calculating the weight difference of the centrifugal canisters on both sides; 7 selecting a counter weight of which the weight approaches to the weight difference of the two centrifugal canisters from standard counter weights, and putting the counter weight on the lighter side; 8, repeating the step 2 to the step 7 to complete the weighting of all the centrifugal canisters; 9, automatically centrifuging; 10, grabbing the centrifuged blood collection tubes out of the centrifugal canisters by using the mechanical hands, placing the blood collection tubes on an uncapping station, and putting the counter weights back; and 11, automatically uncapping the blood collection tubes. The invention also discloses equipment for automatically separating the serum.

Description

technical field [0001] The invention relates to a serum separation method and equipment. Background technique [0002] During medical operations, doctors often need to collect the patient's blood, and separate the serum from the collected blood so that the serum can be used for biochemical, immune, hormone and other detections. [0003] The existing operating procedures for serum separation are completely manual. During operation, medical personnel manually place the test tube containing blood from the test tube rack into the centrifuge barrel of the centrifuge, and then start the centrifuge for centrifugation. After the centrifugation is completed, the test tubes in the centrifuge are manually taken out, or the caps are manually removed, or placed on other capping equipment for cap removal. Such manual serum separation action is not only time-consuming and laborious, but also when performing these operations, the operator's hands directly touch the blood collection tube, ...

AI Technical Summary

Problems solved by technology

Due to factors such as low ambient temperature or too short time, it is often unable to meet the requirements of complete blood coagulation

For now, the judgment of whether the serum is coagulated depends entirely on the visual inspection of the operator's eyes. The accuracy of this visual judgment is extremely low, and after centrifugation, fibrin filaments / blocks will float in the serum, which will affect the quality of the serum and seriously will block the detection instrument

[0006] At the same time, before the centrifugation operation, if the blood collection tube itself has been broken, then in the process of high-speed centrifugation, the strong centrifugal force often causes the test tube to break, resulting in the loss of blood samples

Moreover, the aerosol produced by the broken test tube seriously endangers the health of operators
