　　The company's flagship product, the "Xin Zhang" brand "Gastric Window Acoustic Contrast Agent" (abbreviated as "Gastric Window"), is a Class III medical device product in China and a patented invention by Dr. Guo Xinzhang, an expert in gastrointestinal ultrasound contrast, as early as 1985.
　　Product application scope: Administered orally to enter the gastrointestinal tract, used for ultrasound imaging diagnosis of gastric tumors, ulcers, and other diseases.
　　The clinical application of oral "Gastric Window" helps eliminate the "blind spot in left upper abdominal ultrasound examination," expands the scope of ultrasound examination for the stomach and adjacent organs, and enables clearer visualization of important organs such as the pancreas, left kidney, spleen, and retroperitoneal blood vessels, significantly improving the level of ultrasound diagnosis and differential diagnosis for common and complex gastric diseases.
　　Over the years, the clinical value and significance of "Gastric Window" have been affirmed by many experts and professors in the medical ultrasound field and published in various professional journals and books domestically and internationally. Among these, the achievement of "Clinical Application Technology of Gastric Window Ultrasound Contrast" was included in the "Zhejiang Science and Technology Chronicle" published by Zhonghua Book Company in 1996; in 2005, the "Gastric Window" ultrasound contrast diagnostic method was compiled into the book "Advances in Clinical Oncology" by renowned Chinese medical experts Sun Yan and Wu Mengchao, published by China Union Medical University Press; in September 2012, it was listed in the "Twelfth Five-Year" National Key Audio-Visual Publication Planning Project of the Chinese Medical Association Physician Training Program, "Clinical Application and Progress of Gastroduodenal Ultrasound Contrast Examination," successfully released by Chinese Medical Electronic Audio-Visual Publishing House.
　　The introduction of the patented "Gastric Window" product provides patients with a safe, effective, non-invasive, painless, and cross-infection-free new method for gastrointestinal ultrasound examination, facilitating the early and timely detection of various gastroduodenal diseases. It has broad clinical application value and can serve as a cross-sectional imaging technique to complement the shortcomings of X-ray gastrointestinal contrast and endoscopy.
　　In addition, the company also produces "Medical Ultrasound Coupling Gel." The product uses imported high-molecular water-soluble sound-conducting materials, resulting in extremely high transparency, excellent sound conduction, and optimal coupling effects, with no irritation to the skin or mucous membranes. Meanwhile, the company also distributes various medical consumables and medical products such as electrocardiogram paper.
