Abstract

The invention provides a three-degree-of-freedom front arm blood collection robot and solves the defect of manual needle insertion for blood drawing at present. The three-degree-of-freedom front arm blood collection robot comprises a worktable, wherein a first drive arm, a second drive arm and a needle inserting mechanism are arranged on the worktable, the first drive arm and the worktable form rotatable connection through a first joint, the second drive arm and the first drive arm form rotatable connection through a second joint, the needle inserting mechanism and the second drive arm form rotatable connection through a third joint, the needle inserting mechanism comprises a rectangular frame, a driving motor, a ball screw, a guide sliding rail and a movable sliding table, the driving motor is connected with the ball screw, bearings are sheathed between the two ends of the ball screw and the rectangular frame, a screw hole and a sliding hole are formed in the movable sliding table, a nut is connected into the screw hole in a penetrating manner, the nut is sheathed on the ball screw to form thread connection, a guide sliding barrel is connected into the sliding hole in a penetrating manner, the guide sliding barrel is sheathed on the guide sliding rail to form sliding connection, and the side part of the movable sliding table is fixedly connected with a blood drawing needle. The three-degree-of-freedom front arm blood collection robot adopts mechanical blood drawing, the needle inserting accuracy is high and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments, and relates to a needling operation for venous blood drawing, in particular to a three-degree-of-freedom forearm blood-taking robot. Background technique [0002] Blood routine examination is one of the most extensive and basic inspection items in clinical examination. Through the analysis of blood cells, we can understand the changes in the number and shape of blood cells in patients, which is helpful for better early diagnosis of diseases. [0003] At present, there are three main sources of blood routine samples: peripheral blood collection, venous blood and peripheral diluted blood, and the results measured by different blood collection methods will have certain differences. In routine blood tests, venous blood sampling can avoid many influencing factors, and is accurate and stable for a long time. It can directly reflect the patient's condition and is widely used. [0004] Blo...
