Guo Hao Dai, a professor of bioengineering at Northeastern University in the United States, is an ambitious and innovative person dedicated to advancing 3D bioprinting to revolutionize modern medical treatment. Specifically, Dai focuses on 3D bioprinting biopsy to explore angiogenesis and further treat vascular disease. Vascular diseases, including diseases such as aneurysms, Raynaud's Syndrome, and lymphedema, are caused by abnormal blood vessels, and millions of people in the United States alone The trouble of such diseases. Associate Professor Dai, from the Department of Bioengineering, hopes to advance the treatment of vascular disease through his specially designed 3D bioprinter.
It is well known that conventional desktop and even industrial 3D printers cannot be used for 3D bioprinting because organic materials are too "fragile" for "rude" machines. 3D bioprinters must be very "exquisite". As Dai explained: "There is a very gentle process to build a living tissue. If we use an industrial 3D printer to print living tissue, the cells simply cannot survive."
To overcome this challenge, Dai developed his own 3D bioprinter and accompanying software to print cultured tissue for human disease modeling and drug discovery. Since his research focuses on vascular and vascular regeneration, researchers have used his machine to make small-channel 3D printed vascular-functional tissues. Although Dai still can't print human tissue in 3D, he believes his current work is industry-leading. "It’s just a step in adding blood flow to the organization," he said.
To date, Dai's 3D bioprinting project has received a lot of support, as it aims to advance stem cell research in the vascular field, and in 2014 won the National Science Foundation CAREER Award and received the National Institutes of Health (NIH) and the American Heart. Association funding. Dai's ultimate goal is to develop an innovative approach to the treatment and exploration of vascular and vascular related diseases.

(1) According to the working mode, it can be divided into wet urine analyzer and dry urine analyzer. The dry urine analyzer is mainly used to automatically evaluate the results of the dry test paper method. Because of its simple structure and convenient use, it is widely used in clinical practice.
(2) According to the classification of test items, it can be divided into 8 items, 9 items, 10 items, 11 items, 12 items, 13 items and 14 items. The testing items included urinary protein, urinary glucose, urinary pH, urinary ketone body, urinary bile erythroplasm, urinary bile gen, urinary occult blood, nitrite, urinary white blood cell, urinary specific gravity, vitamin C and turbidity.
(3) According to the degree of automation, it can be divided into semi-automatic urine analyzer and automatic urine analyzer.
YD-200 urine analyzer is a kind of adopt latest optoelectronic technology and microprocessor technology for Clinical urine test; it is user-friendly, and accurate. URS-11A urine strip is dedicated for YD-200. YD-200 can provide 11 items results of quantitative or semi-quantitative for Urobilinogen, Bilirubin, Ketone, Blood, Protein, Micro-albumin ,Nitrite, Leucocytes, Glucose, Specific gravity, pH, Vitamin C.
