The invention relates to the field of
medical instruments, in particular to an arteriovenous puncture instrument, which comprises a
system computer, color ultrasonic diagnosis
software or a portable ultrasonic diagnosis instrument, cross-shaped cursor positioning display
software, cursor positioning computation confirmation sound and misplacement alarm sound
software, and is characterized in that: a puncture positioning connecting rod 1-2 is a sterile
assembly which is positioned and assembled in a sliding piece interface 1-16 of the arteriovenous puncture instrument; an ultrasonic
transducer 1-1 is used for transmitting
ultrasound for acquiring arteriovenous
blood vessel positioning data; a computer ultrasonic transduction
assembly 15 is used for performing
data conversion on information of a three-dimensional positioning-sensing
assembly 1-11; and a three-dimensional positioning sliding piece 1-12 is used for automatically or manually controlling the sterile puncture positioning connecting rod 1-2 to position and puncture arteriovenous blood vessels. Due to the adoption of the arteriovenous puncture instrument, puncture treatment can be guided quickly and accurately, the puncture accuracy is increased, the puncture difficulty is lowered, the efficiency is increased, important organs are prevented from being hurt accidentally, surrounding
tissue damage and complicating diseases are reduced, and the
first aid success rate is increased.
