Problems solved by technology

First of all, in terms of sampling, most testers are resistant to direct contact with feces, and it is difficult to quantify; second, when testing in a hospital, the test may be delayed due to lack of desire to defecate, and it is difficult to store samples after sampling at home and transportation problems, thus affecting the detection effect; thirdly, hospital professionals need to use a quantitative buffer to dissolve the feces first, and then drop the feces liquid into the sample hole of the test strip, and the whole process may appear Problems with leakage and odor, and the need to look directly at and touch stool samples many times
Moreover, it is carried out on an open table. When there are a large number of specimens, it is easy to confuse the samples, which brings various inconveniences to medical staff, and is not suitable for non-professionals to carry out independent determination.

Embodiment 1

[0067] Example 1 structure

[0068] refer to Figure 1 ~ 9 According to the present invention, a fecal sampling and occult blood self-test integrated means are proposed by the main casing 1, a sample rod 2, a discharge valve 3, a upper cover 4, a lower cover 5, a test strip 6; a sample rod groove 7 Contains a sample rod sealing ring 8, the discharge valve discharge groove 9 and the water supply valve sealing groove 10 each contain one release valve seal ring 8. The main housing 1 is combined by a first tubular cavity 12 and a second lumen 13. The upper cover 4 is appropriate to the second tubular cavity top opening 23, and the lower cover 5 is similar to the bottom cross section of the main casing 1. The sampling rod convex end 14 has a diameter of the inner diameter of the detection port 15. The bottom diameter of the discharge valve 3 is closely fit to the first lumen 12, and the discharge valve is provided with a lock (second latch) 16 and the main housing discharge valve port l...

Embodiment 2

[0074] Example 2 installation order

[0075] 1. Place a seal 8 in the sampled rod groove 7, and each seal ring 8 is placed in the liquid water valve sealing groove 10, and the seal is preliminary assembly process.

[0076] 2. Align the lower cover 5 and the main housing bottom end 19, and the lower cover 5 is welded to the main casing 1 and sealed by ultrasonic welding machine.

[0077] 3. Insert the test strutter 6 from the top of the main housing into the second duct chamber 13.

[0078] 4. Put the test strip 22 in the test strip groove 21, and complete the installation of the test strip 22.

[0079] 5. Align the upper cover 4 and the second tubular cavity, and the upper cover 4 is welded to the main housing 1 by ultrasonic welding machine and sealed.

[0080] 6. Plug the discharge valve 3 into the lower cover 24 until the discharge valve lock (second lock) 16 is locked with the main casing discharge valve port (first lock) 17.

[0081] 7. Inject the storage liquid from the dete...

Embodiment 3

[0082]Example 3 Method for use

[0083] 1. Unplug the sample rod 2, collect the feces sample using the acquisition end 25 of the sample rod.

[0084] 2, insert the sample rod 2 into the first duct 12, the shake of the appliance, so that the feces is sufficiently mixed with the liquid in the tube.

[0085] 3, pull the discharge valve 3 pull away from the card position 26 such that the first lucrative chamber 12 is in communication with the second tubing chamber 13, and the liquid flows from the water port 18 of the first lumen 12 to the second lumen 13. The test strip is in contact with the liquid, and the liquid starts running strip detection by the chromatography of the strip.

[0086] 4. After 10 min, observe the color of the test line and the color line of the test line and the quality control line, and the test results are determined by the color card.

Abstract

The invention provides a detection device for fecal occult blood, which is composed of a main casing, a sampling stick, a water discharge valve, an upper cover, a lower cover, and a test paper holder. The device integrates the functions of fecal sample collection, dissolution, chromatography, and test strip detection. It can complete sample collection and immunoassay fecal occult blood detection at one time. Self-check. The device is easy to carry and operate, low in cost, simplifies the detection process, does not need to open fecal liquid in the whole process, and can realize independent detection by the tester, which reduces the burden on medical staff, improves the screening rate of colorectal cancer, and reduces the risk of colorectal cancer. morbidity and mortality.

Description

Technical field [0001] The present invention relates to the field of medical devices, and in particular, the present invention relates to a fecal hidden blood detecting device. Background technique [0002] Fecal hidden blood is an early warning of digestive tract lesions. At this time, there is a small amount of bleeding in the digestive tract. It does not cause color changes in stool, and there is no abnormal change in the appearance of the stool. It is difficult to observe under the naked eye and microscope. The hidden blood test is low, non-invasive, and patient compliance is better, and it is currently one of the clinical routine testing projects, which can effectively screen colorectal cancer. At present, there are mainly immunization and chemical methods of fecal blood, but the traditional chemical method is low, it is extremely susceptible to factors such as diet, drugs. The immunoassay strip detection is based on antigenic antibody reactions, high specificity, has become...
