Description

Blood mixing device for blood sampling of nurses

Technical Field

The utility model relates to the technical field of blood mixing and shaking, in particular to a blood mixing and shaking device for blood sampling of nurses.

Background

In hospitals, nurses often need to collect blood from patients, primarily for the purpose of obtaining a blood sample from the patient for laboratory examination or analysis, thereby helping doctors to diagnose diseases or monitor changes in conditions. Blood collection may provide data for various blood indicators, such as red blood cell count, white blood cell count, hemoglobin level, blood glucose, liver function indicators, kidney function indicators, and the like. These indicators may provide critical information about the patient's physical condition, thereby helping the physician determine the treatment regimen. After the blood is collected, the blood sample is typically collected in a tube with an anticoagulant that prevents the blood from clotting, but they need to be evenly dispersed to have an effective anticoagulation. Thus, the nurse is required to shake the tube to ensure that the anticoagulant is adequately dispersed in the blood.

However, the existing mixing and shaking mode is generally that a nurse holds test tubes and shakes the test tubes manually, if the number of patients is large, a plurality of test tubes filled with blood samples can be generated after the patients are sampled in sequence, in order to improve the mixing and shaking efficiency of the test tubes, the nurse generally holds the test tubes to shake together, but under the condition that the test tubes are shaken simultaneously, the shaking degree of each test tube cannot be guaranteed to be the same, and therefore the mixing uniformity of anticoagulants in the test tubes can be influenced, and the uniformity and the accuracy of detection results are influenced. Therefore, we propose a blood mixing device for blood collection of nurses.
