Embodiment 1

[0023] Example 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 image ...

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 invention relates to a venipuncture system with infrared guidance and ultrasonic location. The venipuncture system is characterized by comprising an infrared guidance unit and an ultrasonic location unit, wherein the infrared guidance unit comprises an infrared light source, a signal acquisition unit, an infrared image processing unit, an image projection unit and an infrared image display unit; the ultrasonic location unit comprises a high-frequency ultrasonic probe, an ultrasonic image processing unit, an ultrasonic image display unit and a puncture needle connection frame fixed on the ultrasonic probe. According to the system provided by the invention, superficial vein blood vessels can be positioned and displayed through infrared imaging, and the depth of the vein blood vessels also can be identified through the ultrasonic unit under the guidance of an infrared image, so that a needle entering angle and the depth of a puncture needle can be observed in real time, and furthermore, the venipuncture difficulty is reduced and the puncture precision is improved.

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 ...
