Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a convenient specimen collection device. Background Technology

[0002] Fecal examination is one of the routine clinical laboratory tests used to understand whether a patient's digestive tract has inflammation, bleeding, parasitic infection, malignant tumors, etc. It can indirectly judge the functional status of the gastrointestinal tract, pancreas, and hepatobiliary system based on the characteristics and composition of the stool, and understand whether the distribution of intestinal flora is reasonable.

[0003] The applicant has discovered that the prior art has at least the following technical problems:

[0004] Existing stool sample collection devices consist of a collection structure and a collection container. The collection structure mostly uses an open, spoon-like design. After collecting the stool sample, the collection structure needs to be placed inside the collection container, relying on the stool sample to naturally detach from the structure and fall into the container. Later, when retrieving the stool sample from the collection container for testing, because the stool sample adheres to the container, the collection structure must be used to scoop it out. The entire collection process is cumbersome and complex, increasing the difficulty of operation. It not only easily contaminates hands or the environment but also easily contaminates the stool sample, affecting the accuracy of the test results.

[0005] Furthermore, existing collection methods often only reach the surface of the feces when collecting samples, which may result in the collection of samples containing urine, affecting the accuracy of the test results.

[0006] Furthermore, due to the open structure of the collection setup, it is difficult to accurately control the amount of specimen collected.

[0007] For example, application number CN201320145903.X discloses a disposable stool specimen collection cup.

[0008] In view of the above, this utility model is hereby proposed. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figures 1-2 As shown, this utility model provides a fecal specimen collection device, including a housing 1, and a drive assembly, a transmission assembly, and a collection assembly movably disposed on the housing 1. The transmission assembly is connected to the drive assembly. The collection assembly includes a collection part 12 and collection connectors 13. The collection part 12 has a collection opening 1201 for receiving fecal specimens. There are multiple collection connectors 13, which are arranged at intervals along the circumference of the collection part 12. One end of the collection connector 13 is connected to the transmission assembly, and the other end is connected to the collection opening 1201. Driven by the transmission assembly, the collection part 12 switches between an open state and a closed state. When it is in the open state, the collection opening 1201 is exposed; when it is in the closed state, the collection opening 1201 is closed, thereby realizing the storage of fecal specimens.

[0030] By integrating the drive component, transmission component, and collection component onto the housing 1, a pen-shaped stool sample collection device is formed. This rationally designed structure simplifies the operation process, reduces the risk of contamination, protects the integrity of the stool sample, and improves the accuracy of test results. It also makes the sampling and storage process more efficient and faster.

[0031] By pressing the drive head assembly, the user can activate the transmission assembly to flexibly switch the collection unit 12 between open and closed states, enabling convenient opening and closing of the collection opening 1201. Throughout the process, the user will not directly contact the specimen, thus reducing the risk of hand contamination. Simultaneously, it also reduces the possibility of environmental pollution, ensuring the hygiene of the collection process.

[0032] When the collection section 12 is in the open state, the collection opening 1201 is exposed, allowing the stool sample to enter or be released. This also allows for some control over the amount of stool sample collected, ensuring the appropriate amount of stool sample. In addition, the collection section 12 can be inserted deep into the feces before closing, reducing the possibility of urine mixing into the stool sample and improving the accuracy of the test results.

[0033] When the collection section 12 is in the closed state, the collection opening 1201 is sealed, effectively protecting the fecal specimen inside the collection section 12 from external contamination.

[0034] As an optional implementation, such as Figure 1 , Figure 2 As shown, the driving assembly includes a pressing plate 2, a sliding block 3, a sliding seat 4, an elastic arm 5, and a driving rod 6. The housing 1 has a receiving cavity 103 for accommodating the sliding block 3, the sliding seat 4, the elastic arm 5, and the driving rod 6. The pressing plate 2, the sliding block 3, the sliding seat 4, and the driving rod 6 are connected sequentially along the direction close to the collection part 12. The sliding block 3 is slidably connected to the receiving cavity 103. The fixed end of the elastic arm 5 is disposed on the sliding seat 4, and its free end is provided with a first protrusion 501. The housing 1 is provided with a first positioning groove 101 and a second positioning groove 102 along its axial direction that are adapted to the first protrusion 501. The first end of the driving rod 6 is connected to the transmission assembly, and the second end of the driving rod 6 is connected to the sliding seat 4.

[0035] Furthermore, the pressing plate 2 is located outside the housing 1, and the user can trigger the entire driving process by pressing the pressing plate 2.

[0036] The sliding block 3 has a cylindrical structure and is slidably connected to the receiving cavity 103 so that the sliding block 3 can move smoothly in a specific direction within the receiving cavity 103.

[0037] The corner of the sliding seat 4 is slidably connected to the receiving cavity 103.

[0038] The elastic arm 5 is inclined upward from its fixed end to its free end. This arrangement allows the elastic arm 5 to deform when subjected to external force and return to its original shape after the external force is removed.

[0039] The function of the drive rod 6 is to convert the movement of the sliding seat 4 into the rotation of the transmission component, thereby driving the acquisition unit 12 to open or close.

[0040] As an optional implementation, such as Figure 1 , Figure 2 As shown, a back clamp 7 is provided on the housing 1, and a second protrusion 701 is provided on the back clamp 7 at the position corresponding to the first positioning groove 101.

[0041] The back clip 7 allows the device to be mounted on other equipment for easy movement and transport.

[0042] As an optional implementation, such as Figure 1 , Figure 2 As shown, it also includes a spring 8, one end of which is connected to the drive rod 6, and the other end is connected to the receiving cavity 103.

[0043] The function of spring 8 is to provide a restoring force, driving the drive rod 6 to move the elastic arm 5 back to its original position.

[0044] The back clip 7 has a certain elasticity. When the user presses the free end of the back clip 7, it can drive the second protrusion 701 into the first positioning groove 101 and squeeze the first protrusion 501 out of the first positioning groove 101. The spring 8 releases its stored elastic potential energy, driving the drive rod 6 to move the elastic arm 5 back to its original position, and the first protrusion 501 re-enters the second positioning groove 102. During this process, the collection unit 12 switches from the open state to the closed state.

[0045] As an optional implementation, such as Figure 1 , Figure 2 As shown, the transmission assembly includes a sector gear 9 and a worm gear 10. The sector gear 9 is mounted on the acquisition connector 13 and connected to the housing 1 via the mounting base 11. The worm gear 10 is mounted on the first end of the drive rod 6 and meshes with the sector gear 9.

[0046] Furthermore, the sector gear 9 is connected to the mounting base 11 via a rotating shaft.

[0047] When the drive rod 6 moves in a specific direction, the worm gear 10 moves synchronously. Due to the meshing of the worm gear 10 and the sector gear 9, the movement of the worm gear 10 will drive the sector gear 9 to rotate the acquisition connector 13, thereby opening or closing the acquisition opening 1201 of the acquisition part 12.

[0048] As an optional implementation, such as Figure 1 , Figure 2 As shown, a receiving groove is provided on the first end of the housing 1 for the sector gear 9 to pass through.

[0049] This configuration provides space for the sector gear 9 to pass through and mesh with the worm gear 10, and also improves the smoothness of the sector gear 9 during rotation.

[0050] As an optional implementation, the cross-section of the acquisition connector 13 is an arc surface.

[0051] Furthermore, the acquisition unit 12 is disposed on the inner wall surface of the acquisition connector 13, providing stable support for the opening and closing of the acquisition unit 12.

[0052] The collection section 12 is made of elastic and tough plastic or rubber, giving it good deformation capability. In the closed state, the collection section 12 can form a spherical closed receiving cavity 103 for better storage of fecal specimens. In the open state, the collection section 12 can adapt to expansion well under the action of the collection connector 13, making it easier to open and collect fecal specimens, thus improving collection efficiency.

[0053] The number of data acquisition connectors 13 can be designed to be three, four, or more, depending on the usage requirements.

[0054] As an optional implementation, such as Figure 1 , Figure 2 As shown, the acquisition opening 1201 of the acquisition unit 12 is connected to the first end of the acquisition connector 13 and extends horizontally to the outside of the acquisition connector 13 to form a horizontal section 1202. The part of the acquisition unit 12 near the worm gear 10 is not directly connected to the acquisition connector 13.

[0055] When the collection section 12 is in the closed state, the horizontal sections 1202 abut against each other to form an effective sealing structure, preventing leakage of fecal specimens and external contamination.

[0056] The part of the collection section 12 near the worm gear 10 is not directly connected to the collection connector 13. This design allows this part of the collection section 12 to deform when it is in the open state, so as to better collect the specimen.

[0057] As an optional implementation, such as Figure 1 As shown, it also includes a sealing cover 14, an internal thread section 1401 is provided on the inner wall surface of the sealing cover 14, an external thread section 104 adapted to the internal thread section 1401 is provided on the outer wall surface of the housing 1, and a sealing ring 1402 is provided between the sealing cover 14 and the housing 1.

[0058] The sealing cap 14 is used to cover and protect the collection component and the fecal specimen inside.

[0059] Through the screw connection of the internal thread section 1401 and the external thread section 104, the sealing cap 14 and the housing 1 can be tightly joined together, which not only effectively prevents external pollutants from entering, but also effectively prevents the leakage of fecal specimens during storage.

[0060] The design of the 1402 sealing ring further enhances the sealing effect.

[0061] As an optional implementation, such as Figure 1 As shown, a corrosion inhibitor 15 is provided on the inner top wall of the sealing cap 14.

[0062] The preservative 15 is adhered to the inner top wall of the sealing cap 14 by an adhesive.

[0063] The function of preservative 15 is to extend the preservation time of fecal specimens and prevent them from deteriorating or rotting during storage. The type and selection of preservative 15 can be designed according to specific usage requirements.

[0064] The working principle of this utility model:

[0065] like Figure 1 As shown, in the initial state, the collection unit 12 is in a closed state to prevent leakage of fecal samples or external contamination. At this time, the first protrusion 501 of the elastic arm 5 is located in the second positioning groove 102, achieving locking so that the collection unit 12 remains closed when not needed.

[0066] like Figure 2 As shown, when it is necessary to open the collection section 12 to collect or release a fecal specimen, the user presses the pressing plate 2, triggering the driving process, which drives the sliding block 3 to move within the receiving cavity 103 in a direction close to the collection section 12. The sliding block 3 drives the sliding seat 4, the elastic arm 5, and the driving rod 6 to move synchronously, causing the first protrusion 501 to disengage from the second positioning groove 102 and enter the first positioning groove 101. During this process, the worm gear 10 moves synchronously with the movement of the driving rod 6. Since the worm gear 10 meshes with the sector gear 9, the movement of the worm gear 10 drives the sector gear 9 to rotate the collection connector 13, thereby opening the collection opening 1201 of the collection section 12 to facilitate the collection or release of the fecal specimen. At this time, the spring 8 is in a compressed state.

[0067] When the collection section 12 needs to be closed, the user presses the free end of the back clamp 7, driving the second protrusion 701 into the first positioning groove 101 and squeezing the first protrusion 501 out of the first positioning groove 101. Subsequently, the spring 8 releases its stored elastic potential energy, driving the drive rod 6 to move the elastic arm 5 back to its original position, and the first protrusion 501 re-enters the second positioning groove 102, thus re-locking the device. During this process, the worm gear 10 moves synchronously with the movement of the drive rod 6. Since the worm gear 10 meshes with the sector gear 9, the reverse movement of the worm gear 10 drives the sector gear 9 to rotate the collection connector 13 in the opposite direction, thereby closing the collection opening 1201 of the collection section 12, so that the fecal specimen is safely sealed inside the collection section 12.
