Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically an integrated fecal occult blood detection device. Background Technology

[0002] Fecal occult blood testing is one of the important technologies for early diagnosis and population screening of colorectal cancer. Colonoscopy for those with positive fecal occult blood can increase the tumor detection rate by 4-6 times, making it the best method for screening high-risk groups for colorectal cancer.

[0003] Routine fecal occult blood testing requires the subject to collect a stool sample for testing by hospital professionals. However, due to the stringent requirements for specimen preservation and transportation during stool collection and testing, people undergoing physical examinations at hospitals often neglect to submit their stool samples due to a lack of urgency. Therefore, the actual stool sampling and testing rate in population screening and physical examinations is low. In reality, the colloidal gold immunochromatographic assay for fecal occult blood is very simple to perform, similar to a pregnancy test, and can be easily done at home by community residents who can then interpret the results themselves.

[0004] Current colloidal gold immunoassay test strips on the market suffer from problems such as complex structure, easy leakage during transportation leading to inaccurate testing, and susceptibility to misuse. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide an integrated fecal occult blood detection device, which solves the problem of inaccurate testing due to leakage during transportation, and also solves the problem of easy misoperation of the detection device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated fecal occult blood detection device, comprising a housing, a sampling rod slidably sleeved inside the housing, a limiting silicone block contacting the outer side of the sampling rod, the limiting silicone block being fixedly connected to the housing, a scraper slidably sleeved on the outer side of the sampling rod, the scraper being interference-fitted with the housing, a sealing silicone contacting the bottom of the sampling rod, the sealing silicone being snapped into the housing, a test strip holder fixedly connected inside the housing, a test strip being snapped into the test strip holder, a test solution stored inside the housing, a sealing ring slidably sleeved inside the housing, the sealing ring being snapped into the sampling rod, a venting groove being provided inside the housing, a venting hole being provided inside the housing, and a limiting mechanism being provided on the sampling rod.

[0007] Preferably, the sampling rod has multiple threaded grooves at its end, and these grooves are evenly distributed on the sampling rod. This threaded groove design makes it easier to collect feces and ensures that the feces scraped by the scraper meet the testing requirements.

[0008] Preferably, the sampling rod has an internal slot, and a sealing ring is engaged inside the slot. This slot design allows the sealing ring to be securely fitted onto the outside of the sampling rod.

[0009] Preferably, a limiting block is engaged with the outer side of the toilet scraper, and the limiting block is fixedly connected to the housing. By designing the limiting block, the toilet scraper can be limited to prevent it from moving.

[0010] Preferably, the limiting mechanism includes fixed rods. Two symmetrically distributed fixed rods are fixedly connected inside the housing. A spring is provided on the outer side of each fixed rod, and a slider is slidably sleeved on the outer side of each fixed rod. The slider is slidably connected to the housing. A ball is fixedly connected to one end of the slider, and the ball is fixedly connected to the housing. An arc-shaped block is fixedly connected to the other end of the slider, and the arc-shaped block is slidably connected to both the housing and the sampling rod. By designing this limiting mechanism, the sampling rod can be limited and locked.

[0011] Preferably, one end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the housing. The spring is designed so that its force can be applied to the slider.

[0012] Preferably, the sampling rod has a groove inside, and an arc-shaped block is slidably connected inside the groove. By designing the groove, the arc-shaped block can slide relative to the sampling rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the design of a limiting silicone block, can prevent the sampling rod from being accidentally pressed down during transportation, or from the user accidentally pressing down the sampling rod before sampling, thus preventing instrument failure. Furthermore, when the user needs to press down the sampling rod, they only need to tear open the silicone pad at the tear point of the limiting silicone block to insert the sampling rod. This provides a preventative function, is easy to operate, and improves the user experience. The test liquid is sealed with sealing silicone; during use, simply press down with the sampling rod to push out the sealing silicone to achieve the desired effect. It is convenient, quick, and simple, and overcomes the leakage problem common in current market products.

[0015] 2. This utility model, through the design of the arc-shaped block, and the insertion of the arc-shaped block into the groove, can limit the sampling rod and fix the sampling rod inside the housing. During transportation and carrying, it can prevent the sampling rod from shaking and slipping out of the housing, thus improving the stability of the detection device during transportation and carrying, and preventing the leakage of test liquid caused by the sampling rod detaching.

A sealing ring 10 is slidably sleeved inside the housing 1 and is snapped into the sampling rod 2. A slot 11 is opened inside the sampling rod 2, and the sealing ring 10 is snapped into the slot 11. By designing the slot 11, the sealing ring 10 can be snapped onto the outer side of the sampling rod 2.

[0023] Please see Figure 1 , Figure 2 , Figure 3The sampling rod 2 has multiple threaded grooves 9 at its end, which are evenly distributed on the sampling rod 2. The design of the threaded grooves 9 makes it easier to collect feces and ensures that the feces scraped by the scraper 4 meet the testing requirements. The housing 1 has a ventilation groove 12 and a ventilation hole 13 inside. The scraper 4 is snapped with a limiting block 14 on its outside. The limiting block 14 is fixedly connected to the housing 1. The limiting block 14 can limit the scraper 4 to prevent it from moving. The sampling rod 2 is provided with a limiting mechanism 15.

[0024] Please see Figure 1 , Figure 2 , Figure 4 The limiting mechanism 15 includes a fixed rod 151. Two symmetrically distributed fixed rods 151 are fixedly connected inside the housing 1. A spring 152 is provided on the outside of the fixed rod 151. One end of the spring 152 is fixedly connected to the slider 153, and the other end of the spring 152 is fixedly connected to the housing 1. By designing the spring 152, the force of the spring 152 can act on the slider 153. The slider 153 is slidably sleeved on the outside of the fixed rod 151. The slider 153 is slidably connected to the housing 1. One end of the slider 153 is fixedly connected to a ball 154, which is fixedly connected to the housing 1. The other end of the slider 153 is fixedly connected to an arc-shaped block 155. The arc-shaped block 155 is slidably connected to the housing 1 and the sampling rod 2 respectively. A groove 156 is provided inside the sampling rod 2. The arc-shaped block 155 is slidably connected inside the groove 156. By designing the groove 156, the arc-shaped block 155 can slide relative to the sampling rod 2. By designing the limiting mechanism 15, the sampling rod 2 can be limited and locked.

[0025] The specific implementation process of this utility model is as follows: In use, the limiting silicone block 3 can prevent the sampling rod 2 from being accidentally pressed during transportation, and prevent the instrument from failing due to the user accidentally pressing the sampling rod 2 before sampling; and when the user needs to press the sampling rod 2, the limiting silicone block 3 is first torn off the housing 1, and then the sampling rod 2 is pressed down to press the sampling rod 2 in; it plays a preventive role and is easy to operate, improving the user experience. The test liquid 8 is sealed with sealing silicone 5. In use, the test liquid 8 can be discharged into the test strip 7 by simply pressing down the sampling rod 2 to push out the sealing silicone 5, which has the advantages of being convenient, fast and simple; and it overcomes the disadvantage of easy leakage in the current market.

[0026] Through the action of the arc block 155, the insertion of the arc block 155 into the groove 156 can limit the sampling rod 2 and fix the sampling rod 2 inside the housing 1. During transportation and carrying, it can prevent the sampling rod 2 from shaking and slipping out of the housing 1, thus improving the stability of the detection device during transportation and carrying, and preventing the leakage of the test liquid 8 caused by the detachment of the sampling rod 2.

[0027] When sampling is required, pull the sampling rod 2 upward. The arc surface of the groove 156 inside the sampling rod 2 will squeeze and push the arc block 155. The arc block 155 will drive the slider 153 to slide along the fixed rod 151 and squeeze the spring 152. At the same time, the slider 153 will squeeze the ball 154, which can separate the arc block 155 from the groove 156. Then the sampling rod 2 can be pulled out from the inside of the housing 1, and the stool can be sampled through the sampling rod 2.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
