Problems solved by technology

[0007] However, in general blood drawing or injection, veins with slow blood flow must be selected, and no obvious Doppler frequency shift effect can be produced, and it is even more difficult to distinguish them from the surrounding static soft tissues; Determine whether there is a moving object, but cannot provide axial (axial) analysis, in other words, cannot know the depth of the moving object

Embodiment Construction

[0036] The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings.

[0037] Referring to Fig. 5 and Fig. 6, the preferred embodiment of ultrasonic vein detection device 1 of the present invention comprises a pulse type ultrasonic emission unit 21, an ultrasonic sensing unit 22, a pulse type pressurization unit 3, a microprocessor 4, and A storage unit 5 .

[0038] In the ultrasonic probe 2, a pulsed ultrasonic transmitting unit 21 and an ultrasonic sensing unit 22 are included. The transmitting unit 21 has an oscillator made of piezoelectric material, so that when the transmitting unit 21 receives the driving signal of the microprocessor 4 , a discontinuous one-directional pulsed ultrasonic signal is generated.

[0039] For the purpose of illustration, the pulse pressurization unit 3 in this embodiment is an example of an annu...

Abstract

An ultrasonic device and method for detecting the position of vein features that the pulse pressure signals different from heart pulses are output to a position to be detected to human body for forcing the blood flow in vein to become pulse mode, which makes the ultrasonic echo have Doppler shift used to detect the position of vein and calculate its depth.

Description

technical field [0001] The invention relates to a vein detection device and method, in particular to a device and method for detecting the position of veins by ultrasonic signals. Background technique [0002] At present, for the medical behavior of using endoscope to penetrate into the human body to perform surgery or to treat tumors with radiation, in order to ensure accuracy without damaging surrounding tissues and cells, other methods such as X-ray scanning and magnetic resonance imaging (MRI) are often used. and other objective aids. Allows the operator to have objective images for reference and comparison, and even complete simultaneous monitoring during treatment. [0003] In contrast, when general subjects or patients receive blood tests or drug injections, experienced medical staff only select appropriate vein needles to draw blood samples or perform injections, and there is no similar objective reference data for comparison. However, the veins and blood vessels a...
