SDSW Medical Device Technology Corporation is committed to the R&D and manufacturing of PET erythrocyte sedimentation tubes and vacuum blood collection tubes.
As the company's representative product – vacuum blood collection tube, in order to reduce the error of blood extraction volume, SDSW has optimized the original blood collection tube dozens of times, and each optimization is accompanied by destructive experiments with thousands of samples. It took half a year to finally reduce the error to 5%, which is a leap-forward breakthrough compared to the 10% error required by the international community.
New PET erythrocyte sedimentation tube
SDSW is the only company in China and the third company in the world that can produce erythrocyte sedimentation tubes made of PET, and the price of products of the same quality is about 40% lower than the other two. At present, the products have been applied to the market in many countries.
The erythrocyte sedimentation tube is an essential product for clinical testing, and it is divided into glass and PET materials. Among them, PET material has become the first choice for clinical testing because of its characteristics of complete sterilization, high anti-infection and convenient operation.
"PET material has extremely strict technical requirements in terms of verticality. It is difficult to control the ratio of the material, and it is difficult to maintain a good verticality when the length exceeds 100 mm, and verticality is the key to ensuring the accuracy of clinical detection.
After understanding the production of the mold, SDSW started a bold attempt: changing the inherent shape of the mold with the same thickness in the middle, top and bottom, and adjusting the thickness of the top and bottom of the mold in units of 10 mm to make it a T-shaped design.
Following destructive experiments with thousands of samples, after four months, SDSW finally found the "optimal value" – when the upper end reaches 40 mm and the lower end reaches 90 mm, the verticality of the PET material up to 130 mm is still good. .
As a "stuck neck" technology, SDSW conquered it in only 4 months. Such "efficiency" also made SDSW the focus of the industry in an instant. It successfully won 2 invention patents and 23 utility model patents, which were harvested globally. 42 partners.
