Description

Technical Field

[0001] This utility model relates to the field of fecal sample collection technology, and in particular to a fecal sample collector for colorectal cancer detection. Background Technology

[0002] Colorectal cancer generally refers to cancer of the large intestine. Typically, colorectal cancer can be detected through methods such as fecal occult blood tests, colonoscopy, and imaging examinations. Specific details are analyzed below:

[0003] 1. Fecal occult blood test: Colorectal cancer is a general term for cancers that occur in the rectum and colon, and may manifest as abdominal pain, bloody stools, and abdominal masses. The fecal occult blood test is used to detect hidden red blood cells, hemoglobin, or transferrin in the stool. If a patient has colorectal cancer, the fecal occult blood test will usually be positive.

[0004] 2. Colonoscopy: Colonoscopy is an examination method in which a colonoscope is inserted through the anus into the ileocecal junction to observe colonic lesions from the mucosal side. Patients can go to the hospital to undergo colonoscopy, which helps in the diagnosis of colorectal cancer.

[0005] 3. Imaging examinations: Patients can also undergo imaging examinations, which can generally present local images through X-rays, showing the location and extent of colorectal cancer.

[0006] In the prior art, Chinese utility model patent CN220508429U discloses a fecal sample collector for colorectal cancer detection, comprising: a sample collection component; the sample collection component includes a cap; a movable collection component; the movable collection component includes a connecting block installed at the bottom of the cap, a connecting rod connected below the connecting block, a dirt-proof cover disposed outside the connecting rod, a collection block installed below the dirt-proof cover, and a fixing block connected outside the collection block; and a collection placement component. This utility model solves the problem that existing sample collectors only have one collection method, but the feces from colorectal cancer may be either hard or loose; therefore, two collection methods are required, but these require two separate containers.

[0007] Problems compared to existing technologies: Some existing fecal sample collectors have poor protection during use. When the collector is dropped, the fecal sample is easily spilled and it is inconvenient to quickly open the fecal sample collector.

[0008] Therefore, there is an urgent need for a stool sample collection device for colorectal cancer detection. Utility Model Content

[0009] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fecal sample collector for colorectal cancer detection.

[0010] The present invention solves its technical problem through the following technical solution: It includes a container, an end cap installed above the container, and a protective mechanism located below the end cap for protecting the fecal sample collector. It also includes connecting mechanisms located at both ends of the end cap for quickly opening or closing the fecal sample collector. The protective mechanism includes multiple arc-shaped plates made of plastic. The arc-shaped plates are fixed to the bottom of the end cap by bolts. Multiple protective rings, which are elastic airbags, are evenly installed on the inner wall of the arc-shaped plates. A base plate is fixed to the bottom of the arc-shaped plates by bolts. A lifting block is fixed to the bottom of the base plate by bolts. A retaining ring is slidably connected to the outer side of the lifting block. A base is fixed to the bottom of the retaining ring by bolts. A damping rod is fixed to the middle of the base by bolts. A helical spring is fixed to the outer side of the damping rod by bolts.

[0011] As a further embodiment of this utility model: the connecting mechanism includes a mounting ring, which is fixed to the top of the container by bolts. The mounting ring has triangular slots at both ends. The end cap has sliding rods slidably connected to both ends. One end of the sliding rod is fixed to a top block by bolts. The end cap has a receiving groove on the side near the top block. A tension spring is fixed to the outside of the sliding rod by bolts.

[0012] As a further embodiment of this utility model: an extraction mechanism is provided in the middle of the end cap for extracting fecal samples. The extraction mechanism includes a nut, which is fixed to the top of the end cap by bolts. A screw is provided in the middle of the nut, and an extraction spoon is rotatably connected to one end of the screw. A turntable is fixed to one end of the screw by bolts.

[0013] As a further improvement of this utility model, a sponge pad is provided on the top of the base plate.

[0014] As a further improvement of this utility model, the inner wall of the end cap is fixed with a sealing gasket by bolts.

[0015] As a further improvement of this utility model, a pull ring is rotatably connected to one end of the slide rod.

[0016] As a further improvement of this utility model, a telescopic cover is fixed to the outside of the screw by bolts.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. Pull the sliding rod with the pull ring to pull the top block into the receiving groove. Under the elastic action of the tension spring, the top block presses tightly against the triangular slot, thereby pressing the end cap tightly on top of the container, allowing for quick installation of the end cap. Similarly, the end cap can be quickly removed.

[0019] 2. Multiple protective rings and arc-shaped plates work together to buffer the lateral impact of the container, the helical spring buffers the impact of the base, and the damping rod handles the excessive bounce of the helical spring, thus providing all-round protection for the fecal sample collector and preventing it from falling and spilling the fecal sample.

[0020] 3. By rotating the screw through the turntable, the screw's rotational motion is converted into lifting motion under the threaded action of the nut, thereby driving the extraction spoon to rise and fall. This allows the fecal sample collector for colorectal cancer detection to extract fecal samples from different depths inside the collector, enriching the functionality of the fecal sample collector for colorectal cancer detection.

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] Example 1:

[0036] like Figure 1-5As shown, a fecal sample collector for colorectal cancer detection includes a container 200, an end cap 100 mounted above the container 200, and a protective mechanism located below the end cap 100 for protecting the fecal sample collector. It also includes connecting mechanisms located at both ends of the end cap 100 for quickly opening or closing the fecal sample collector. The protective mechanism includes multiple arc-shaped plates 101, each made of plastic, which are bolted to the bottom of the end cap 100. The inner walls of the arc-shaped plates 101 are evenly fitted with… There are multiple protective rings 102, each of which is an elastic airbag. A base plate 103 is bolted to the bottom of the arc-shaped plate 101. A sponge pad 110 is attached to the top of the base plate 103, protecting the bottom of the container 200. A lifting block 104 is bolted to the bottom of the base plate 103. A retaining ring 105 is slidably connected to the outside of the lifting block 104. A base 106 is bolted to the bottom of the retaining ring 105. A coil spring 108 is bolted to the outside of the damping rod 107. The impact of the base 106 is buffered by a damping rod 107 bolted to the middle of the base 106. The damping rod 107 handles the excessive bounce of the coil spring 108. A sealing gasket 210 is bolted to the inner wall of the end cap 100, ensuring the seal between the end cap 100 and the container 200. The connecting mechanism includes a mounting ring 201, which is bolted to the top of the container 200. The mounting ring 201 has triangular grooves 202 cut at both ends. The two ends of the end cap 100... A sliding rod 203 is slidably connected, and a pull ring 220 is rotatably connected to one end of the sliding rod 203. The pull ring 220 pulls the sliding rod 203 to move it. A top block 204 is fixed to one end of the sliding rod 203 by bolts. The top block 201 presses against the triangular groove 202. The end cap 100 has a receiving groove 205 cut on the side near the top block 204. The receiving groove 205 receives the top block 204. A tension spring 206 is fixed to the outside of the sliding rod 203 by bolts. The tension spring 206 pulls the sliding rod 203, causing the top block 204 to press tightly against the triangular groove 202.

[0037] In this embodiment, during use, the sliding rod 203 is first pulled by the pull ring 220 to pull the top block 204 into the receiving groove 205, and the end cap 100 is placed on top of the container 200. The pull ring 220 is then released, and under the elastic action of the tension spring 206, the top block 204 presses tightly against the triangular slot 202, thereby pressing the end cap 100 tightly on top of the container 200 for quick installation. Similarly, the end cap 100 can be quickly disassembled. During the transfer of fecal samples, multiple protective rings 102 cooperate with the arc plate 101 to buffer the lateral impact on the container 200, the helical spring 108 buffers the impact on the base 106, and the damping rod 107 handles the excessive jumping of the helical spring 108, thereby providing all-round protection for the fecal sample collector and preventing it from falling and spilling fecal samples.

[0038] Example 2:

[0039] like Figure 1-6 As shown, a fecal sample collector for colorectal cancer detection includes an extraction mechanism located at the center of the end cap 100 for extracting fecal samples. The extraction mechanism includes a nut 301, which is bolted to the top of the end cap 100. A screw 302 is threadedly connected to the center of the nut 301, converting the rotational motion of the screw 302 into a lifting motion. A telescopic cover 310 is bolted to the outside of the screw 302 to protect it. An extraction spoon 303 is rotatably connected to one end of the screw 302, and a turntable 304 is bolted to the other end of the screw 302, causing the screw 302 to rotate.

[0040] In this embodiment, the screw 302 is rotated by the turntable 304. Under the threaded engagement of the nut 301, the rotational motion of the screw 302 is converted into a lifting motion, thereby driving the extraction spoon 303 to rise and fall. This allows the fecal sample collector for colorectal cancer detection to extract fecal samples from different depths inside the collector, enriching the functionality of the fecal sample collector for colorectal cancer detection.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
