Automatic blood drawing device

Abstract

The invention relates to the technical field of medical instruments, in particular to an automatic blood drawing device. The automatic blood drawing device comprises a blood drawing experiment table,a bearing and blocking-up part, a positioning and fastening part and a positioning and blood drawing part. The bearing and blocking-up part comprises a positioning driving assembly arranged in the blood drawing experiment table, and a positioning and blocking-up assembly installed at the output end of the positioning driving assembly and used for bearing the elbow of a person subjected to blood drawing. The positioning and fastening part comprises a limiting and fastening assembly arranged on the blood drawing experiment table and a fastening driving assembly for driving the limiting and fastening assembly to move. The fastening driving assembly is in transmission connection with the limiting and fastening assembly. The positioning and blood drawing part comprises a vertically-arranged bearing driving assembly and a limiting and blood drawing assembly arranged at the output end of the bearing driving assembly. In a working state, the limiting and blood drawing assembly is in butt jointwith the bearing driving assembly. Automatic blood drawing is adopted, the task load of medical nurses is reduced, and harm of needle heads and other sharp instruments to the medical nurses is also avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic blood drawing device. Background technique [0002] Routine blood examination is one of the most extensive and basic inspection items in clinical examination. Through the analysis of blood cells in blood routine samples, we can understand the changes in the number and shape of blood cells in patients, which is helpful for clinical diagnosis of diseases. Early diagnosis. At present, the sources of routine blood samples mainly include peripheral blood collection, venous blood collection and peripheral diluted blood, and the results measured by different blood collection methods will have certain differences. Among them, venous blood collection can avoid many influencing factors, and the measurement is accurate and accurate. The stable time is long and can directly reflect the physical condition of the patient. [0003] As we all know, venous blood vessels are...

Problems solved by technology

For example, relying on the nurses' many years of experience and feel to perform manual puncture, but often inaccurate, especially in the increasing number of obese patients, coupled with infants and ICU (intensive care) ward patients who are more concerned about the needling puncture technology of medical staff In the case of higher and higher requirements, it has caused great pain to patients, and at the same time increased the probability of doctor-patient disputes; in the outpatient blood draw center of the hospital, many patients need to perform blood draw operations every day, and the task of blood draw nurses The amount is very heavy, and it will also increase the damage of sharp objects such as needles to the blood nurse during the blood drawing process
