The invention relates to a blood testing machine which comprises a feeding device, a material taking device, a batching device, a material moving device and a testing device, wherein after a blood sample is collected, a blood sampling tube and other materials are placed in the feeding device, after the feeding device is used for feeding, the material taking device clamps the blood sampling tube and other materials on the feeding device and moves the blood sampling tube and other materials to a set position in the batching device, the blood in the blood sampling tube is sampled by the batching device and added with reagents required by testing to form a sample to be tested, and the material moving device moves the sample to be tested into the testing device for blood testing. Compared with the prior art, the invention basically automates the steps of blood inspection, including specimen conveying, specimen receiving and processing, on-machine inspection and specimen preservation, thereby greatly improving the accuracy and speed of the inspection.
Description
Technical Field
The invention relates to a blood testing machine, and belongs to the technical field of medical instruments.
Background
The basic steps of blood test are: 1. collecting a specimen, and extracting venous blood of a patient by a clinical nurse; 2. conveying the specimen, and immediately conveying the specimen to a clinical laboratory after blood sampling; 3. receiving and processing a specimen, and adding a reagent required by the test into the specimen by a clinical laboratory; 4. and (5) testing and preserving the specimen on a machine. All the above steps require the participation of professionals, so that the blood test requires a large amount of personnel. But the participation of a large number of personnel can not improve the inspection speed and ensure the accuracy of the inspection, and the labor force is wasted and the speed can not be ensured by using the personnel for conveying in the specimen conveying process; when the specimen is processed, the clinical laboratory needs to add reagents according to the blood test requirement of each patient, and errors such as wrong addition and missing addition are easy to occur due to manual addition, so that the test result is abnormal.
