Full-automatic venous blood sampling device

Abstract

The invention discloses a full-automatic venous blood sampling device which comprises a syringe needle positioning mechanism, a blood sampling point identifying and treating mechanism connected to the syringe needle positioning mechanism, and an arm fixing positioning mechanism and a needle replacing mechanism arranged on the syringe needle positioning mechanism. The syringe needle positioning mechanism comprises a lead screw transmission assembly, a ballscrew assembly and a three-degree-of-freedom mechanical arm. The lead screw transmission assembly comprises a fixed support and a stand column connected to the fixed support in a sliding mode. The ballscrew assembly is connected to the stand column and the three-degree-of-freedom mechanical arm, and used for driving the three-degree-of-freedom mechanical arm to move left and right. The three-degree-of-freedom mechanical arm comprises a fixing plate, a second mechanical arm body, a first mechanical arm body and a slide block, wherein the two ends of the first mechanical arm body are rotatably connected with the fixing plate and the second mechanical arm body correspondingly, the slide block is connected to the second mechanical arm body in a sliding mode, and a syringe needle is arranged on the slide block.

Description

technical field [0001] The invention belongs to the related technical field of medical instruments, and more specifically relates to a fully automatic venous blood collection device. Background technique [0002] Medical personnel frequently collect blood samples during physical examination and diagnosis of patients or during daily physical examinations; most of them currently use traditional blood collection methods, which require manual operation and the level of equipment is backward. In the process of manual blood drawing, the operation is difficult and the risk factor is high, and medical personnel with certain work experience are required to complete it well. [0003] In the traditional blood collection work, blood vessels cannot be clearly displayed due to thick fat and dark skin in some patients, resulting in puncture failure and low efficiency, which brings inconvenience to doctors and patients. At present, those skilled in the art have done some research. For exam...

Problems solved by technology

[0002] Medical personnel frequently collect blood samples during physical examination and diagnosis of patients or during daily physical examination; most of them still use traditional blood collection methods, which require manual operation and the level of equipment is backward

In the process of manual blood drawing, the operation is difficult and the risk factor is high, and medical personnel with certain work experience are required to complete it well

[0003] In traditional blood collection work, blood vessels cannot be clearly displayed due to thick fat and dark skin in some patients, resulting in puncture failure and low efficiency, which brings inconvenience to doctors and patients

At present, those skilled in the art have done some research. For example, the invention with the application number 201310514069.1 discloses a blood collection device and method, which adopts automatic and intelligent blood collection, but still needs manual installation of blood collection needles and blood vessel punctures. to a lesser extent
