Description

Technical Field

[0001] The utility model relates to the technical field of early screening detection of colorectal cancer, in particular to an early screening detection device for colorectal cancer. Background Technique

[0002] Colorectal cancer is a common malignant tumor in the gastrointestinal tract. Its early symptoms are not obvious. As the cancer mass grows, it shows symptoms such as changes in bowel habits, blood in the stool, diarrhea, alternation of diarrhea and constipation, and local abdominal pain. In the early screening of colorectal cancer, a detection device is needed for detection. The commonly used early screening method is the fecal occult blood test, which usually needs to be carried out in multiple steps, that is, first put the stool on the test paper, and then drop 3% hydrogen peroxide on the feces and the test paper.

[0003] After retrieval, the patent with the publication number CN218848161U discloses an early screening detection device for colorectal cancer. However, the early screening detection device for colorectal cancer has the following deficiencies in use:

[0004] Although the stool can be detected by the test paper and the hydrogen peroxide in the storage box during use, after the feces are put into the detection box, it cannot be ensured that the hydrogen peroxide in the storage box can just drop on the feces and the test paper, which brings inconvenience to the testers. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiency that although the stool can be detected by the test paper and the hydrogen peroxide in the storage box during use, after the feces are put into the detection box, it cannot be ensured that the hydrogen peroxide in the storage box can just drop on the feces and the test paper, which brings inconvenience to the testers in the prior art, and to propose an early screening detection device for colorectal cancer.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An early screening detection device for colorectal cancer, including a detection box, a detection test paper for detection, and a liquid storage tank for storing hydrogen peroxide. The bottom of the detection test paper is fixedly connected to the inner wall of the bottom of the detection box. The top of the detection box is threadedly connected with a cover body, and the liquid storage tank is filled with hydrogen peroxide;

[0008] A spraying mechanism, which is arranged on the cover body for spraying hydrogen peroxide on the feces and the detection test paper;

[0009] A limiting mechanism, which is arranged on the liquid storage tank for limiting the spraying mechanism to prevent accidental pressing.

[0010] In a possible design, the spraying mechanism includes a spraying tank, a connecting pipe, a push rod and a piston. The top of the spraying tank is fixedly connected to the inner wall of the top of the cover body. The bottom end of the connecting pipe is fixedly connected to and communicates with the top of the spraying tank. The top end of the connecting pipe penetrates through the top of the cover body. Internal threads are provided on the inner wall of the connecting pipe. External threads are provided on the outer side of the bottom end of the liquid storage tank. The bottom end of the liquid storage tank is threadedly connected to the connecting pipe. A moving hole is provided in the top of the liquid storage tank. The outer side of the push rod is slidably connected to the inner wall of the moving hole. The outer side of the piston is slidably connected to the inner wall of the liquid storage tank. The bottom end of the push rod is fixedly connected to the top of the piston. The piston is made of rubber material. A plurality of spraying holes are provided in the bottom of the spraying tank. Hydrogen peroxide is located between the piston and the spraying tank. A push handle is fixedly provided at the top end of the push rod.

[0011] In a possible design, the limiting mechanism includes a first blocking block and a second blocking block. Semi-circular grooves for accommodating the push rod are provided on the sides of the first blocking block and the second blocking block that face each other. Two slots are provided on one side of the first blocking block. Two iron blocks are fixedly provided on one side of the second blocking block. Magnets are fixedly provided on the inner walls of one sides of the slots. The iron blocks are inserted into the slots. The first blocking block and the second blocking block are located between the push handle and the liquid storage tank.

[0012] In a possible design, an exhaust pipe for exhausting gas is fixedly provided and communicates with one side of the detection box. A one-way valve is provided on the exhaust pipe.

[0013] In a possible design, a filter screen for filtering the odor of feces is fixedly provided at one end of the exhaust pipe.

[0014] In a possible design, anti-slip grooves for increasing the frictional force of the human hand for anti-slip are provided on the cover body.

[0015] In this application, during use, rotate and open the lid to expose the inside of the detection box. Put the feces into the detection box and let it fall on the test paper. Then tighten the lid on the detection box. The first stop block and the second stop block can limit the position of the push rod to prevent accidental touching or pressing of the push handle (the thickness of the first stop block and the second stop block is equal to the distance between the piston pulled to the top of the liquid storage tank and the push handle and the liquid storage tank). Then hold the first stop block with one hand and hold the second stop block with the other hand and pull in the opposite direction to separate the iron block and the magnet. After removing the first stop block and the second stop block, then press down the push handle with your hand. The movement of the push handle makes the push rod and the piston move downward. The piston pushes the hydrogen peroxide in the liquid storage tank into the spraying box and sprays it onto the feces and the test paper through multiple spraying holes. The diameter of the spraying box is the same as the size of the test paper, so as to ensure that the hydrogen peroxide can just drop on the feces and the test paper. The user can observe the situation of the test paper through the detection box (the detection box and the liquid storage tank are made of transparent PP material or transparent acrylic). When the test paper does not change color within 2 minutes, it means that there is no blood in the feces. When the test paper turns blue or dark green, it means that there is blood in the feces, indicating that the person may have colorectal cancer and needs further examination. For the test paper, it is made of degradable thin paper, and a layer of tetramethylbenzidine chromogenic dye and peroxide film is wrapped on the test paper. During use, the ferrous heme in hemoglobin has peroxidase-like activity, can release oxygen through the peroxide film, and oxidize the colorless tetramethylbenzidine into colored benzidine blue, showing blue-green. Since the test paper is a prior art, it will not be described in detail in this specification. The concentration of hydrogen peroxide is 3%. The smell discharged from the detection box can be filtered through the set filter screen to reduce pollution to the surrounding area. The material of the filter screen is an activated carbon filter screen, which can of course be selected according to actual needs. Since the liquid storage tank is installed on the connecting pipe by means of threaded connection, the liquid storage tank can be disassembled to extract hydrogen peroxide. The one-way valve only allows outflow and does not allow inflow.

[0016] The beneficial effects of the present utility model are as follows:

[0017] In the present utility model, for the colorectal cancer early screening detection device, through the spraying mechanism, press down the push handle with your hand. The movement of the push handle makes the push rod and the piston move downward. The piston pushes the hydrogen peroxide in the liquid storage tank into the spraying box and sprays it onto the feces and the test paper through multiple spraying holes. The diameter of the spraying box is the same as the size of the test paper, so as to ensure that the hydrogen peroxide can just drop on the feces and the test paper;

[0018] In the present utility model, for the colorectal cancer early screening detection device, through the limiting mechanism, the first stop block and the second stop block can limit the position of the push rod to prevent accidental touching or pressing of the push handle;

[0019] In the present utility model, the spraying mechanism can ensure that hydrogen peroxide can exactly drip onto the feces and the test paper, and the limiting mechanism can limit the push rod to prevent accidental touching or pressing of the push handle. Brief Description of the Drawings
