Research of a pocket device for rapid combined test of biomedical samples

A pocket device for rapid combined test of biomedical samples is comprised of four parts: strip, strip attached column, sampling head and test tube. One to multiple strips are separately attached to the shallow groove on the surface of the strip attached column. The strip attached column is placed inside the test tube of the device. The sampling head is in front of the test tube. The sampling head has a slim tube type suction nozzle, which is capped with a rubber protection cap. The cavity of the sampling head is front-to-back filled with sample filter material and sample water absorbent material. The sealing cap at the end of the test tube is able to block the waste after testing to prevent leakage. During the sample testing, one removes the rubber protection cap of sampling head suction nozzle and dips the suction nozzle into the test sample. Each strip undergoes once sampling and is detected at the same background. In 3-5 minutes we can concurrently test several indexes of the sample in the transparent areas of test tube with naked eyes. This device has many advantages: small size, low cost, simple, safe and fast operation, and it can effectively prevent detection of cross-interference. Post-test waste is still enclosed in the test tube, which helps to prevent the spread of pathogens and iatrogenic infections, and to dispose waste for environmental protection.
