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] The structure of embodiment 1 device

[0068] refer to Figure 1-9 , the present invention proposes a stool sampling and occult blood self-test integrated device, which is composed of a main housing 1, a sampling stick 2, a water discharge valve 3, an upper cover 4, a lower cover 5, and a test paper holder 6; A sampling rod seal ring 8 is included, and a drain valve seal ring 8 is contained in each drain valve drain groove 9 and drain valve seal groove 10 . The main housing 1 is composed of a first lumen 12 and a second lumen 13. The shape of the upper cover 4 is suitable for the opening 23 at the top of the second lumen, and the shape of the lower cover 5 is suitable for the cross section of the bottom of the main housing 1. The diameter of the protruding end 14 of the sampling rod is closely adapted to the inner diameter of the detection port 15 . Drain valve 3 bottom diameters are closely suitable with the first pipe chamber 12 inner diameters, and the water disch...

Embodiment 2

[0074] Installation sequence of embodiment 2 device

[0075] 1. Place a sealing ring 8 in the groove 7 of the sampling rod, and place a sealing ring 8 in the water discharge groove 9 of the drain valve and the sealing groove 10 of the drain valve respectively, and complete the preliminary assembly process of the seal ring.

[0076] 2. Align the lower cover 5 with the bottom end 19 of the main casing, and use an ultrasonic welding machine to weld the lower cover 5 and the main casing 1 together and seal them.

[0077] 3. Insert the test strip holder 6 into the second lumen 13 from the top of the main housing.

[0078] 4. Put the test strip 22 into the groove 21 of the test strip holder to complete the installation of the test strip 22 .

[0079] 5. Align the upper cover 4 with the top of the second lumen, and use an ultrasonic welding machine to weld the upper cover 4 and the main casing 1 into one body and seal it.

[0080] 6. Insert the drain valve 3 into the drain valve po...

Embodiment 3

[0082]The using method of embodiment 3 device

[0083] 1. Pull out the sampling stick 2, and use the collection end 25 of the sampling stick to collect a stool sample.

[0084] 2. Insert the sampling stick 2 back into the first lumen 12, and shake the device to fully mix the feces with the liquid in the tube.

[0085] 3. Pull down the drain valve 3 to disengage from the clamping position 26, so that the first lumen 12 communicates with the second lumen 13, and the liquid flows from the water port 18 of the first lumen 12 to the second lumen 13. The test strip sample pad is in contact with the liquid, and the liquid starts running strip detection through the chromatographic action of the test strip.

[0086] 4. After 10 minutes of detection, observe the color development of the test line and the quality control line at the pad of the test strip, compare the color card, and judge the test result.

Abstract

The invention provides an excrement occult blood detection device which is composed of a main shell, a sampling rod, a water drain valve, an upper cover, a lower cover and a test paper rack. The device integrates the functions of excrement sample collection, dissolution, chromatography, test strip detection and the like, can finish sample collection and immune excrement occult blood detection at one time, and is suitable for a detector to perform excrement occult blood self-service detection at any place and at any time in families, hospitals and the like. The device is easy and convenient tocarry and operate and low in cost, the detection process is simplified, excrement liquid does not need to be opened in the whole process, self-detection of a detector can be achieved, the burden of medical staff is relieved, the colorectal cancer screening rate is increased, and the occurrence rate and the death rate of colorectal cancer are reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular, the invention relates to a fecal occult blood detection device. Background technique [0002] Fecal occult blood is an early warning of gastrointestinal lesions. At this time, a small amount of gastrointestinal bleeding does not cause changes in the color of the stool, and there is no abnormal change in the appearance of the stool. It is difficult to observe with the naked eye and under a microscope. It can be checked by a fecal occult blood test. Fecal occult blood detection is low-cost, non-invasive, and patient compliance is good. It is currently one of the routine clinical testing items and can effectively screen for colorectal cancer. At present, there are mainly immunological methods and chemical methods for fecal occult blood tests, but the traditional chemical methods have low specificity and are easily affected by factors such as diet and drugs. Immuno-test strip detection ...
