Blood collection instrument

Abstract

The invention relates to a blood collection instrument, which comprises a main body, a scanning device, a mechanical arm, a processor system and a driving system. The scanning device can be movably set on the main body to obtain a distribution diagram of a patient's arm section tissue. The mechanical arm is movably connected with the main body to connect blood vessels and needles. The processor system is connected with the scanning device by communication, and the processor system can determine the position of the blood vessel based on the distribution diagram of the arm's section tissue. Thedriving system is connected with the processor system by communication to drive the scanning device to move, the position adjustment of the mechanical arm and the performing of the puncture action according to the position of the blood vessel. The blood collection instrument improves the accuracy of blood collection puncture. At the same time, the blood collection process can be carried out automatically, which reduces the work intensity of hospital nurses, saves human resources and improves the efficiency of blood collection.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blood sampling instrument. Background technique [0002] Blood sampling is a routine examination method during the hospitalization of patients to determine the patient's biochemical, immune, pathological and other medical clinical indicators. The blood vessels of humans or animals are located in the subcutaneous tissue or inside the body tissue, and blood collection often requires puncture of veins, arteries or tissues. [0003] For a long time, the daily blood collection in clinical laboratory medicine, whether it is physical examination, hospital outpatient or ward blood collection, mainly relies on nurses' years of experience and hand feeling to perform manual puncture. The number of obese patients is increasing, and infants and ICU In wards and other situations where patients have high requirements on medical staff's needle puncture skills, inaccurate needles o...

Problems solved by technology

[0003] For a long time, the daily blood collection in clinical laboratory medicine, whether it is physical examination, hospital outpatient or ward blood collection, mainly relies on nurses' years of experience and hand feeling to perform manual puncture. The number of obese patients is increasing, and infants and ICU In wards and other situations where patients have high requirements on medical staff's needle puncture skills, inaccurate needles often occur, which not only increases the pain of patients, but also increases the probability of doctor-patient disputes

In addition, in some specific inspection processes, repeated blood collection is required at intervals, which will inevitably lead to repeated manual blood collection work, which is extremely consuming of human resources
