Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0020] to combine figure 1 , figure 2 , image 3 As shown in , the patient's deep vein and arterial puncture site are conventionally sterilized and dried, and the conventional surgery is spread with a treatment towel. Put it in a fixed position, press the reset button A1-10 and press the reset button B2-5 to reset to 45°, observe the 45° angle display 1-15 and the 45° angle display 2-4 two windows to confirm 45° at the same time; The puncture connecting rod 1-2 is connected to the transparent plastic cover of the inlet sensor by the puncture connecting rod bag, and the puncture connecting rod docking port 2-7 is docked with the sliding part 1-12 of the puncture instrument; the ultrasonic transducer 1-1 is sterile Coat the ultrasonic catalyst on the ultrasonic window of the outer cover, and use sterile physiological saline to coat the ski...

Abstract

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.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an arteriovenous puncture instrument. [0002] Background technique [0003] At present, the existing arteriovenous puncture is manual puncture, or artificial arteriovenous puncture guided by ultrasound or radiographic contrast; the puncture success rate is low, especially for elderly critically ill and young children.
