Abstract
Description
Technical Field
[0001] This utility model relates to the field of specimen collection technology, and in particular to a device for collecting fecal specimens. Background Technology
[0002] Fecal specimens are among the most commonly used specimens in medical testing, providing indispensable information for the diagnosis, assessment of treatment efficacy, and monitoring of certain diseases. With the development of medical testing technology, especially the application of molecular biology techniques, the amount of disease-related information obtainable from fecal specimens is increasing, and their role in disease diagnosis and treatment is becoming increasingly important. Besides understanding a patient's digestive system function, patient fecal specimens are also used to test for intestinal infections. Some pathogens causing intestinal symptoms, such as cholera, bacterial dysentery, and norovirus, rely on the collection and detection of patient fecal specimens. Therefore, collecting fecal specimens from patients is a common procedure in medical laboratory testing.
[0003] Currently, most medical institutions collect stool samples using small, covered plastic cups. Patients hand the cup containing the stool sample to laboratory personnel, who then open the cup and use a sampling spoon to scoop out the sample. However, manually using the sampling spoon results in inaccurate sample weights, failing to meet the testing requirements. Furthermore, collecting loose stool samples with the spoon poses a risk of splattering, easily contaminating the personnel's hands and posing a health hazard. Utility Model Content
[0004] To address the technical problems of inaccurate sampling weight and the risk of fecal sample splashing when inspectors manually operate a sampling spoon to collect fecal samples, and the ease with which inspectors' hands become contaminated with fecal samples, this utility model provides the following technical solution.
[0005] This utility model discloses a device for fecal specimen sampling, comprising a handle with a receiving cavity and a connecting handle with a display screen at the top connected to the handle. A cover plate is connected above the receiving cavity. A clamping handle with a weighing cavity is connected to the end of the connecting handle away from the handle. A weighing sensor is fixedly provided at the bottom of the weighing cavity. A clamping frame located in the weighing cavity is placed above the weighing sensor. The clamping frame clamps a sampling spoon with a handle end. A knock-off component is provided in the receiving cavity, passing through the connecting handle, the clamping handle, and the clamping frame. The knock-off component includes a push rod that passes through the receiving cavity to the clamping frame and abuts against the handle end.
[0006] As a further technical solution, the knocking component includes a sliding block fixedly connected to the push rod and a pressing block matching the sliding block located in the receiving cavity, and a pressing rod penetrating the cover plate is fixedly connected to the upper part of the pressing block.
[0007] As a further technical solution, a first spring is sleeved on the outer periphery of the portion of the push rod located inside the receiving cavity, and the two ends of the first spring are respectively fixedly connected to the inner wall of the receiving cavity and the sliding block.
[0008] As a further technical solution, a second spring sleeved on the outer periphery of the lower pressure rod is fixedly connected between the lower pressure block and the cover plate.
[0009] As a further technical solution, the sliding block has an upward inclined surface in the direction close to the pressing block, and the pressing block has an inclined surface parallel to the inclined surface of the sliding block.
[0010] As a further technical solution, the inner wall of the clamping frame has several elastic protrusions around its perimeter, and the elastic protrusions elastically abut against the end of the spoon handle.
[0011] As a further technical solution, the clamping handle and the clamping frame are respectively provided with a first through hole and a second through hole located on the same axis for the push rod to slide through.
[0012] The beneficial effects of this utility model are as follows: The clamping handle of this utility model is equipped with a clamping frame and a weighing sensor. When the clamping frame clamps the sampling spoon to collect fecal samples, the weighing sensor can accurately weigh the sample taken by the sampling spoon and display it on the display screen. This enables accurate quantitative sampling of fecal samples, ensuring the testing requirements of fecal samples are met. When the clamping frame clamps the sampling spoon, the inspector holds the handle to collect the fecal sample. The inspector's hands are far from the sampling spoon, which can prevent the fecal sample from splashing. After sampling, the sampling spoon can be knocked off by operating the detaching component, preventing the inspector's hands from being contaminated by the fecal sample and ensuring the safety of the fecal sample collection process.

Detailed Implementation
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0015] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0016] like Figure 1 As shown, this utility model discloses a device for fecal sample collection, comprising a handle 1 and a connecting handle 2 fixedly connected to the handle 1. A clamping handle 3 is connected to the end of the connecting handle 2 away from the handle 1. A sampling spoon 4 is held in the inner cavity of the clamping handle 3 via a clamping frame 6. The sampling spoon 4 is a disposable item used to sample fecal samples from a sample cup. The testing personnel hold the handle 1 to collect the fecal sample. The sampling spoon 4 is kept at a distance from the testing personnel to prevent splashing of the fecal sample and ensure the safety of the testing personnel.
[0017] like Figure 2 and Figure 3As shown, in a preferred embodiment, the handle 1 is a cuboid handle-shaped structure. A receiving cavity 101 is provided on the side of the handle 1 near the connecting handle 2, containing the disengaging component 7. A cover plate 102 is connected above the receiving cavity 101. A display screen 201 is provided on the upper part of the connecting handle 2, and a weighing cavity 302 is provided inside the clamping handle 3. A weighing sensor 5 is fixedly installed at the bottom of the weighing cavity 302. The weighing sensor 5 transmits the measured weight signal to the display screen 201, allowing inspectors to determine whether the fecal sample weight is acceptable by observing the values on the display screen 201.
[0018] At this time, a clamping frame 6 is placed on top of the weighing sensor 5, located inside the weighing chamber 302. The clamping frame 6 holds the sampling spoon 4, which has a handle end 401. The handle end 401 is clamped by the clamping frame 6. During sampling, the weight measured by the weighing sensor 5 is the sum of the weights of the clamping frame 6, the sampling spoon 4, and the fecal sample. Subtracting the weights of the clamping frame 6 and the sampling spoon 4 gives the weight of the fecal sample. Before sampling and weighing, the weights of the clamping frame 6 and the sampling spoon 4 can be zeroed out. Afterward, the weighing method of the weighing sensor 5 adopts the existing method, which will not be described in detail here.
[0019] The clamping frame 6 is a frame structure with an opening on one side. The inner wall of the clamping frame 6 has several elastic protrusions 602 around its perimeter. In this embodiment, the elastic protrusions 602 are located at the lower part of the upper end of the clamping frame 6. The handle end 401 of the spoon can be directly inserted into the clamping frame 6 and elastically pressed against by the elastic protrusions 602. Thus, the clamping frame 6 can elastically clamp the sampling spoon 4, allowing the weighing sensor 5 to weigh the clamping frame 6, the sampling spoon 4, and the fecal sample. It should be noted that the sampling spoon 4 only contacts the clamping frame 6 and does not contact other components to ensure the accuracy of the weighing results.
[0020] like Figure 4 As shown, in a preferred embodiment, the receiving cavity 101 is provided with a knock-off component 7, which is used to knock off the sampling spoon 4 after sampling, avoiding the need for inspectors to disassemble the sampling spoon 4 by hand. At this time, the knock-off component 7 passes through the connecting handle 2, the clamping handle 3, and the clamping frame 6 and can knock the sampling spoon 4, causing it to fall out of the clamping frame 6 into the trash can. Specifically, the knock-off component 7 includes a push rod 701 that passes through the connecting handle 2 and the clamping handle 3 from the receiving cavity 101 and extends through the clamping frame 6. In this embodiment, there are two push rods 701. When the clamping frame 6 clamps the sampling spoon 4, the end of the push rod 701 is exactly abutting the spoon handle end 401. At this time, by operating the push rod 701, the push rod 701 can push the spoon handle end 401 out of the clamping frame 6, causing the sampling spoon 4 to fall out of the clamping frame 6.
[0021] In a preferred embodiment, the disengaging component 7 includes a sliding block 703 located in the receiving cavity 101 and fixedly connected to one end of two push rods 701. The sliding block 703 has an upward inclined surface on the side away from the push rods 701. The sliding block 703 has a structure similar to a wedge. The cover plate 102 is slidably connected to a pressing rod 705. The lower end of the pressing rod 705 is fixedly connected to a pressing block 704. The pressing block 704 matches the sliding block 703. At this time, the pressing block 704 also has a structure similar to a wedge. The pressing block 704 has an inclined surface parallel to the inclined surface of the sliding block 703. When the pressing rod 705 is pressed, the pressing block 704 moves downward and rubs obliquely against the sliding block 703, which will generate a pushing force on the sliding block 703 in the direction of the clamping frame 6. This pushing force can cause the push rod 701 to move towards the clamping frame 6, thereby pushing the spoon handle end 401 out of the clamping frame 6.
[0022] In a preferred embodiment, the clamping handle 3 and the clamping frame 6 are respectively provided with a first through hole 301 and a second through hole 601 located on the same axis for the push rod 701 to slide through. The first through hole 301 and the second through hole 601 facilitate the stable horizontal movement of the push rod 701. Furthermore, a first spring 702 is sleeved on the outer periphery of the portion of the push rod 701 located inside the receiving cavity 101. The two ends of the first spring 702 are respectively fixedly connected to the inner wall of the receiving cavity 101 and the sliding block 703. The elastic force of the first spring 702 facilitates the reset of the push rod 701. A second spring 706 is fixedly connected between the lower pressure block 704 and the cover plate 102 and sleeved on the outer periphery of the lower pressure rod 705. The second spring 706 facilitates the reset of the lower pressure rod 705.
[0023] In use, firstly, insert the sterile sampling spoon 4 into the clamping frame 6 and adjust the display screen 201 to zero the value of the weighing sensor 5; then, hold the handle 1 to operate the sampling spoon 4 to sample the fecal specimen; observe the value on the display screen 201, and after collecting a sufficient amount of fecal specimen, pour the sampled fecal specimen into the sample tube and discard the sample cup; then, press down the lever 705, push the lever 701 horizontally to knock the sampling spoon 4 out of the clamping frame 6 and into the trash can.
[0024] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
