Injections seem to be a very simple exercise, but even for medical professionals, it is a very challenging thing. Especially when encountering some obese, small or fragile patients, venipuncture is even more difficult.
According to statistics, the failure rate of first attempt of venipuncture is 10%-20% for adults and 40% for children. 58% of patients were dissatisfied with the venous puncture level of the nurse. Improper venipuncture can not only cause the patient to suffer from needle sticking many times, but also may cause phlebitis, vascular obstruction or other complications.
So, is there any way to enable medical staff to accurately find the subcutaneous vein and improve the success rate of venipuncture? The arterial network (micro-signal: vcbeat) has compiled 15 domestic and foreign black technology products, including handheld instruments, smart glasses and mobile app, which can help medical staff to accurately pin!
1, VeinViewer Flex venous imager
The VeinViewer Flex venous imager is the market's leading mobile vascular imaging system. With VeinViewer Flex, doctors can see 15 mm of blood vessels in the patient's skin, while blood vessels commonly used in the clinic are generally concentrated 10 mm below the skin. In addition to the surrounding veins and their branches, doctors can see the flow of blood vessels and blood, as well as the flow of drugs in the blood vessels. If the patient has phlebitis or varicose veins, the internal thrombus can be clearly seen through the VeinViewer Flex. Moreover, the vascular lamp of the second-generation VeinViewer Vision2 can also change color, doctors can easily change the image size, brightness, and easily save the image as a PNG file.
The VeinViewer Flex venous imager works by using the absorption of near-infrared light by deoxygenated hemoglobin in the surrounding tissues and veins. The information is photoelectrically converted and image processed, and then projected onto the patient's skin in real time. In this way, the success rate of the first venipuncture of the medical staff can be significantly improved, the puncture time can be shortened, thereby reducing the trauma and pain of the patient, reducing the risk of infection, enabling the patient to get the drug or liquid treatment more quickly, and winning the rescue. time.
The VeinViewer venous imager was developed by Christie Medical Holdings. Christie Medical Holdings, an innovative company that uses optical technology innovation to innovate patient care and health management, is headquartered in Memphis, Tennessee, and was formerly Luminetx, acquired by Christie Digital Systems USA in 2010. The company currently has two main products: VeinViewer Flex and VeinViewer Vision2.

9, Oxy-Amp vein search glasses
Oxy-Amp is designed to take the doctor's normal color vision to a new level, magnifying veins and blood-related health signals on the patient's skin. Oxy-Amp glasses connect human color vision with blood physiology, and different filters built into the product amplify the changes in our subcutaneous oxygen levels and present them in a variety of color halos. One of the filters, called the vein-finder, uses this principle to help the nurses identify the blood vessels by letting the patient's veins gleam.
Working principle: The change of blood flow is very subtle in the color of human skin. It is difficult for the naked eye of ordinary people to judge the condition of the body according to the changes of the skin. The glasses can give different signals to the glasses according to different states of the body. The doctor can see different shades of green, pink and purple from the glasses. Through this intuitive color change, the hidden under the skin can be uncovered. secret.
As for Oxy-Amp's production company VINO, since its inception in 2006, it has been providing color-blind patients and medical workers with glasses with color blind correction and enhanced vein display. In addition to the Oxy-Amp vein finding glasses, VINO has two other flagship products: color-blind corrective glasses and Hemo-ISO trauma-seeking glasses, which are used to correct color blindness and detect bruises and hematomas.
10, VeinSeek Pro blood vessel visualization app
VeinSeek Pro is the world's first smartphone app for vascular visualization. Without the need for additional equipment, the cell can be used to successfully uncover hidden blood vessels under the skin. Currently, VeinSeek Pro only supports iOS devices, and Android devices are estimated to wait a while.
Light of different colors penetrates into the skin at different depths. By removing the signal from the surface layer of the skin, it is easier to see deeper structures. VeinSeek Pro utilizes multispectral imaging principles and the intrinsic optical properties of the skin to produce enhanced vein images. It achieves venous visualization by increasing the difference in absorption of oxyhemoglobin or deoxyhemoglobin, reducing the effects of surface scatter and specularly reflected light on the overall image. The idea of ​​turning an ordinary smartphone into a vein detector is really cool. However, unfortunately this app currently only supports iOS devices, Android devices are estimated to wait a while.
