Embodiment 1

[0023] Embodiment 1: see figure 1, a venipuncture system for infrared-guided ultrasonic positioning, the puncture system includes an infrared guiding unit 101 and an ultrasonic positioning unit 107, the infrared guiding unit 101 includes an infrared light source 102, a signal acquisition unit 103, an infrared image processing unit 104, an image The projection unit 105 or the infrared image display unit 106 , the ultrasound positioning unit 107 includes an ultrasound probe 108 , an ultrasound image processing unit 109 , and an ultrasound image display unit 110 . The infrared light source 102 in this technical solution emits infrared light with a wavelength of 730nm~990nm to irradiate the measured part of the human body, and the signal acquisition unit 103 collects the optical signal and performs signal analysis and processing through the image processing unit 104 to optimize the image. and highlight the blood vessel part to obtain a clear and visible blood vessel image; the ima...

Embodiment 2

[0024] Example 2: see figure 1 , as an improvement of the present invention, the technical solution may further include a distance measuring unit for measuring the distance between the measured part of the human body and the projection unit. The purpose of this design is to prompt the user to keep the distance between the measured part of the human body and the projection unit within a preset range, so as to obtain a better blood vessel positioning effect. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0025] Embodiment 3: see figure 1 , the infrared image processing unit 104 and the ultrasonic image processing unit 109 can be implemented by an FPGA processor, a DSP processor or an ARM processor electronic circuit. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The present invention relates to a superficial vein puncture auxiliary system guided by infrared and ultrasonic positioning, characterized in that the puncture system includes an infrared guiding unit and an ultrasonic positioning unit, and the infrared guiding unit includes an infrared light source, a signal acquisition unit, and an infrared image processing unit , an image projection unit, an infrared image display unit, the ultrasonic positioning unit includes a high-frequency ultrasonic probe, an ultrasonic image processing unit, an ultrasonic image display unit, and a puncture needle connecting frame fixed on the ultrasonic probe. The system can not only locate and display superficial veins through infrared imaging, but also identify the depth of veins through the ultrasonic unit under the guidance of infrared images, so as to realize real-time observation of needle insertion angle and depth of puncture needles, reducing the risk of venipuncture. Difficulty, improve puncture accuracy.

Description

technical field [0001] The invention relates to a venipuncture auxiliary device, in particular to a venipuncture system for infrared-guided ultrasonic positioning, and belongs to the technical field of medical equipment. Background technique [0002] Intravenous infusion is a very important way to slow down the disease and promote the recovery of patients in clinical medicine. Venipuncture is a necessary skill for medical staff, and it requires extremely high professional skills and work experience. At present, most of the venipuncture mainly relies on the medical personnel to carry out the judgment of the blood vessel location through naked eye observation and finger touch. Because the superficial veins are slender, children and obese patients cannot display the veins due to thick subcutaneous fat. The elderly and infirm patients lose elasticity due to long-term venipuncture leading to superficial vein sclerosis, and the veins of patients with edema and dark skin are also ...
