Description

A stool sampling and occult blood self-testing device

technical field

The utility model belongs to medical equipment, relates to a stool sampling and occult blood self-testing device, and is an auxiliary in vitro diagnostic device suitable for hospitals and families.

Background technique

Fecal occult blood detection is one of the important technologies for early diagnosis of colorectal cancer and population screening. Colonoscopy for patients with positive fecal occult blood can increase the tumor detection rate by 4-6 times. Best way. Annual detection of fecal occult blood can significantly reduce the incidence and mortality of colorectal cancer in the population, which has been confirmed by many large-scale cohort studies. Fecal occult blood detection has been recommended by many authoritative organizations such as the American Cancer Society, the Early Diagnosis and Early Treatment Project of Colorectal Cancer of the Ministry of Health of China, and the Digestive Disease Branch of the Chinese Medical Association as the most important screening technology for colorectal cancer in the population.

For routine fecal occult blood testing, the subject needs to collect stool and send it for testing, which is tested by hospital professionals. However, due to the high requirements for the preservation and transportation of specimens for stool collection and inspection, those who go to the hospital for physical examination often ignore or do not have the intention to send stool for inspection. Therefore, in actual population screening and physical examination, the rate of stool sampling submission is low. In a colorectal cancer screening trial conducted in Xiacheng District of Hangzhou, Xuhui District of Shanghai and Nangang District of Harbin, the stool inspection rate of community residents was less than 40%. In fact, the operation method of colloidal gold immune test strips to detect fecal occult blood is very simple, similar to early pregnancy test strips, and community residents can test them at home and judge the results by themselves.

However, stool testing is significantly different from urine testing: First, stool is more easily polluted than urine, and people are reluctant to look directly at or touch stool. Secondly, the feces are solid and need to be fully dissolved in the liquid before the immunoassay can be tested. Again, it is more difficult to control the amount of feces sampled than urine. Finally, it is necessary to ensure that the fecal liquid does not leak during the testing operation, otherwise it is not suitable for home or non-professional home testing. At present, there is no device suitable for self-testing of fecal occult blood on the market. Some manufacturers of immunogold-labeled fecal occult blood reagents have designed their own stool collection devices, but their stool collection devices do not have a sampling volume control device, and none of them include a detector, which is required for all tests. Open fecal fluid. At present, fecal occult blood is only carried out in professional medical institutions. Professionals generally dissolve the feces in a container with buffer solution first, then pour the feces in the container into a small cup or small hole, and then insert the absorbent test paper The strip is inserted into the cuvette or hole for detection. During the test, the fecal liquid is open, and there are many times to look directly at the feces. It is easy to overturn the spilled liquid when operating the small and medium-sized cups and small holes, and it is necessary to wear gloves for operation. The detection equipment is not scattered and not easy to carry and transport. It cannot be determined by non-professionals.
