Embodiment 1

[0023] see Figure 1-4 , the present invention is mainly composed of a cover 1 and a main body container 2, a stool collection rod 3, a stool collection rod guide channel 8, a stool dissolving pool 9, a stool liquid filtration tube 10, a test strip detection tank 11 and a connecting pipe 12. The cover 1 is fixed with a stool collection rod 3, the top of the stool collection rod 3 is a cylindrical fixed end 4, and the rest is a small cylindrical shape, and the cylindrical fixed end 4 is fixed on the inner top wall of the cover 1, and forms a narrow ring column with the inner wall of the cover 1 In the gap, the upper half of the inner wall is engraved with threads, and the lower half is smooth. The tail end of the excrement collection stick 3 has a sharper tip and is engraved with sticky feces threads 7, which are used to contaminate feces. The purpose of the sharp tip of the excrement collection stick 3 It is used to puncture the sealing film on the top of the fecal liquid filt...

Embodiment 2

[0037] see Figure 5-7 , the difference between the utensil provided in this embodiment and Embodiment 1 is that the stool collection stick is not fixed on the inner top wall of the cover, and the stool collection stick is stored separately, and the stool collection stick is inserted into the main container 2 only after the stool collection In the guide passage 8 of the stool picking stick. Lid 1 removes excavating stool rod 3 and its fixed end cylinder 4, and all of its inner walls are threaded. The outer side of the cylindrical channel neck 5 of the excrement rod guide channel 8 is engraved with a push thread 6, which is compatible with the thread on the inner wall of the cover 1, and the other parts and connections of the appliance are the same as those described in embodiment 1.

[0038] Before the stool sampling self-testing device shown in Example 2 is opened for testing, the stool sampling stick 3 is individually packaged. The lid 1 of the excrement stick is completel...

Embodiment 3

[0046] Using the fecal occult blood sampling self-testing device separated from the stool sampling stick shown in Example 2, compared the compliance rate and result accuracy rate of fecal occult blood self-testing and testing with the current stool sample submission method in the urban community population of Xiashi Street, Haining and testing costs.

[0047] Taking the 40-74-year-old population living in two adjacent communities A and B as the research object, 100 fecal occult blood sampling self-test devices and test result recording cards were randomly distributed to the target population in A community, and 100 copies of fecal occult blood sampling self-test devices and test result recording cards were randomly distributed to the target population in B community. 100 stool sampling bottles distributed. Subjects in community A are required to report the results of fecal occult blood self-test through cards, text messages, phone calls, interviews, etc.; community B is requir...

Abstract

The invention provides a device for stool sampling and occult blood self-detection. The device comprises a cover, a main container, a stool sampling rod, a stool sampling rod guide channel, a stool dissolution tank, a stool liquid filter pipe, a communication pipe and a test strip detection tank. The stool sampling rod is fixed to the cover or is not fixed to the cover. A top end of the stool sampling rod is fixed to a top wall of the interior of the cover. The stool sampling rod is inserted into the stool sampling rod guide channel. The bottom of the stool liquid filter pipe is connected to the bottom of the test strip detection tank by the communication pipe. The device realizes quantitative acquisition, dissolution, filtration and immune test strip detection of a stool sample, does not produce liquid leakage in storage, conveying and detection, realizes stool sampling and occult blood self-detection in a single cycle, avoids stool direct viewing, is convenient for carrying, operation and cleaning, and is suitable for stool occult blood self-detection carried out by an average adult at any time or place. The device has a reasonable design, a simple structure and a low production cost, is convenient for operation, avoids stool liquid opening, realizes one-step detection after stool sampling, and is clean and safe.

Description

technical field [0001] The invention 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 [0002] 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...
