Portable dynamic venous blood collection device

Technical field

The invention relates to the technical field of medical and health auxiliary equipment, specifically a portable dynamic venous blood collection instrument.

Background technique

Various blood tests in the medical and health industry require artificial venous blood collection. Some testing experiments require repeated blood collection at multiple times, such as the growth hormone stimulation test to diagnose growth hormone deficiency, the gonadotropin release test to diagnose true precocious puberty, etc. etc., it is necessary to collect venous blood from patients at different time points of 30, 60, 90, and 120 minutes. Manual operation often results in inaccurate time, and even misses the blood collection time, resulting in experimental failure. Children patients' fear of venipuncture causes compliance with the operation. Poor sex. The present invention solves many of the above drawbacks. It uses an embedded chip to control the blood collection time and blood collection volume. It not only realizes the automation of venous blood collection, but also the portable feature of the invention greatly alleviates patients' fear of venous blood collection and improves the efficiency of venous blood collection.
