Release date: 2016-05-17 Recently, a military vehicle engineer named Alex Stanciu designed a 3D printed venography camera. Stanciu believes that he designed this $23 DIY device, which is about five times cheaper than similar products on the market. It is suitable for nurses and medical staff in developing countries. It is well known that collecting blood samples and performing intravenous injections is a common phenomenon in hospitals today. But even a very professional nurse sometimes has no veins, because some patients may not be born with natural veins. At this time, the use of a venous phenotype will solve this problem, quickly find the veins, prevent unnecessary troubles, and improve the patient's confidence in the medical team. Unfortunately, the professional venulators on the market today are not cheap. Although a few hundred dollars in a large hospital in the United States may not be worth mentioning, it does pose problems for small medical teams in some parts of the world. And Stanciu's girlfriend is a nurse who lacks experience in finding veins, so Stanciu did some research on the venography. Since buying a device like this might cost most of Stanciu's girlfriend's monthly salary, for this reason, Stanciu decided to use a 3D printer and some very economical electronic components. After a lot of prototype and product iterations, Stanciu finally developed a near-perfect design. This design is ideal for printing on inexpensive 3D printers without heated print beds. To eliminate warpage, Stanciu used blue tape and alcohol on the print bed. The 3D printed venography camera consists of three components, and it takes an estimated 4-5 hours to print them all in 3D. Stanciu uses an i3 RepRap 3D printer. In order to fight for faster printing. Stanciu set the layer height to 0.25 mm, but he suggested that the layer height can be set to 0.1 mm if the quality of the appearance is sought. Of course, in addition to the 3D printed part, the maker has to prepare some other components, such as resistors, batteries and battery contacts. But the most important of these 15 LED lights, the wavelength of these LEDs should be between 620 and 680 nm, and the brightness should be between 4000 and 6000 MCD. Light like this can penetrate the skin, adipose tissue and oxygenated blood, but it cannot penetrate hypoxic blood. Therefore, it is easy to highlight veins with less blood oxygen. It is understood that Stanciu sent the design file of this 3D printing vein imager to the Internet for free download, and hoped that users can share it on a non-commercial basis.
