Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a detection device for screening and examining gastrointestinal tumors. Background Technology

[0002] In the medical field, early screening for gastrointestinal tumors is crucial for improving patient survival rates and treatment outcomes. Currently, gastrointestinal tumor screening typically requires collecting and testing gastrointestinal samples from patients; however, existing testing devices have many shortcomings in sample collection, processing, and equipment maintenance.

[0003] In terms of sample collection, the traditional device's collection component structure is not well-designed, making it difficult to accurately control the collection pressure and volume, which can easily lead to sample damage or insufficient collection, affecting the accuracy of subsequent tests. Moreover, the position adjustment of the collection head is not flexible enough to adapt to the testing needs of different patients, and there is a lack of an effective pressure monitoring mechanism during the collection process, making it impossible to detect and resolve collection abnormalities in a timely manner.

[0004] During sample processing, existing devices often suffer from poor stirring, making it difficult to thoroughly mix the samples and affecting the release of effective components. Furthermore, the lack of adequate heating and ultrasonic oscillation assistance results in low processing efficiency for samples requiring specific temperatures or high-frequency vibrations for complete lysis. In addition, gases generated during sample processing are emitted directly without effective filtration, potentially causing environmental pollution and posing health risks to operators.

[0005] Regarding equipment maintenance, the cleaning mechanism has design flaws, resulting in incomplete disinfection and a high risk of bacterial and viral residues in the collection head, increasing the risk of cross-infection. Furthermore, the lack of effective drying measures during cleaning means that damp collection heads not only easily breed microorganisms but also affect the accuracy of subsequent sample collection. In addition, the existing device is not convenient to move and fix, making it difficult to adapt to different testing scenarios and impacting testing efficiency.

[0006] Therefore, the purpose of this invention is to provide a detection device for screening gastrointestinal tumors, in order to overcome the shortcomings of the prior art. Summary of the Invention

[0018] This invention provides a detection device for screening gastrointestinal tumors. It has the following beneficial effects:

[0019] 1. This invention uses a telescopic rod in the sample collection mechanism to push the main rod out, and then slides through a transparent protective cover. The collection head collects samples under the negative pressure of a micro vacuum pump, while a pressure sensor monitors the pressure to achieve precise sampling. This not only ensures the accuracy and stability of sample collection, but also allows for adjustments to the collection process based on pressure data, avoiding sample damage or insufficient collection due to abnormal pressure, thus meeting the stringent sample quality requirements for gastrointestinal tumor screening.

[0020] 2. This invention uses a motor in the sample processing mechanism to drive a rotating rod, shaft, and stirring blade to stir the sample. A wiping plate wipes the container wall, and the sample is heated by a heating element. An ultrasonic oscillation device further facilitates the complete lysis of the sample. A pressure sensor monitors the pressure inside the container, and an air filtration device filters the gas. This achieves efficient sample processing, not only enabling the sample to fully lyse under stirring, heating, and ultrasonic oscillation to release effective components, but also ensuring the safety and stability of the processing through pressure monitoring and air filtration, providing high-quality samples for subsequent testing.

[0021] 3. This invention uses ultraviolet lamps in the cleaning mechanism for disinfection, telescopic rod 2 to push the connecting plate, and motor 2 to drive the cleaning pad for wiping. At the same time, heating element 2 heats and assists in disinfection and drying, achieving efficient cleaning and disinfection of the sampling head. This not only effectively kills bacteria and viruses on the sampling head and prevents cross-infection, but also accelerates drying through heating, extending the service life of the sampling head and ensuring the hygiene, safety and sustainable use of the detection device.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a detection device for screening gastrointestinal tumors, including a base plate 1 with multiple casters 2 at the bottom. Two fixed plates 3 are fixedly installed on one side of the upper part of the base plate 1, and a top plate 4 is fixedly installed on the upper part of the two fixed plates 3. Multiple drawers 5 are arranged between the two fixed plates 3, and a cabinet 6 is fixedly installed between the two fixed plates 3. A sample collection mechanism 7 is fixedly installed on the other side of the upper part of the base plate 1. The sample collection mechanism 7 includes a main component and a sampling component, which is used to collect samples. A sample processing mechanism 8 is fixedly installed on the other side of the upper part of the base plate 1. The sample processing mechanism 8 includes a stirring component, an air filtration component, and an auxiliary component, which is used to stir the collected samples. A cleaning mechanism 9 is also fixedly installed on the other side of the upper part of the base plate 1. The cleaning mechanism 9 includes a disinfection component, a cleaning component, and a heating component, which is used to disinfect and clean the collection structure.

[0033] The main components of the sample collection mechanism 7 include a placement platform 701 fixedly installed on the other side of the upper part of the base plate 1. A main rod 702 is placed inside the placement platform 701. A telescopic rod 703 is fixedly connected to one end of the main rod 702. A transparent protective cover 704 is slidably connected to the outside of the main rod 702. A collection head 705 is fixedly connected to one end of the transparent protective cover 704. The output end of the telescopic rod 703 is fixedly connected to the rear end of the collection head 705.

[0034] Specifically, the main component of the sample collection mechanism 7 is based on a placement platform 701 fixed on the base plate 1. The placement platform 701 is hollow inside and can accommodate the main rod 702. The main rod 702 is a hollow metal rod that serves both structural support and sample transfer functions. One end of the main rod 702 is fixedly connected to a telescopic rod 703, which is an electric push rod that can drive the main rod 702 to extend or retract axially, thereby adjusting the position of the collection head 705. A transparent protective cover 704 is fitted over the outside of the main rod 702 and can slide with the main rod 702. This cover serves to prevent dust and contamination of the main rod 702 and its internal pipelines. The front end of the transparent protective cover 704 is fixedly connected to the collection head 705, and the output end of the telescopic rod 703 directly acts on the rear end of the collection head 705, ensuring that the collection head 705 remains stable and accurately aligned with the sample collection position during extension and retraction.

[0035] The sampling assembly includes multiple sampling holes 706 located at the front end of the sampling head 705, a miniature vacuum pump 707 installed inside the sampling head 705, a connection port 708 located at the other end of the main body rod 702, a connecting line 709 fixedly connected to one side of the chassis 6, one end of the connecting line 709 being connected to the connection port 708, a sample delivery hose 710 fixedly connected to one side of the outer wall of the sampling head 705, and a pressure sensor 711 fixedly installed on the other side of the outer wall of the sampling head 705.

[0036] Specifically, the collection head 705 has multiple collection holes 706 at its front end, evenly distributed to ensure sample aspiration from multiple angles. A miniature vacuum pump 707 is integrated inside the collection head 705; upon startup, it generates negative pressure to draw biological samples through the collection holes 706. A connection port 708 is located at the other end of the main body rod 702, connecting to the chassis 6 via a connecting cable 709, enabling power supply and start / stop control of the miniature vacuum pump 707. A sample delivery hose 710 is connected to one side of the outer wall of the collection head 705, with the other end of the hose leading directly to the sample processing mechanism 8. The collected sample is transferred to the subsequent processing unit through the hose under negative pressure. A pressure sensor 711 is installed on the other side of the outer wall of the collection head 705 to monitor the negative pressure value in real time during the collection process. When the pressure is abnormal, the pressure sensor 711 feeds a signal back to the control system, triggering an alarm or automatic adjustment mechanism to prevent sample collection failure or contamination.

[0037] The stirring assembly in the sample processing mechanism 8 includes multiple bases 801 fixedly installed on the other side of the upper part of the base plate 1. A stirring tank 802 is fixedly installed on one side of the upper part of the multiple bases 801. A U-shaped plate 803 is fixedly installed on the upper part of the stirring tank 802. The inside of the stirring tank 802 is fixedly connected to one end of the sample delivery hose 710. A motor 804 is fixedly installed at the bottom of the U-shaped plate 803. A rotating rod 805 is fixedly connected to the output end of the motor 804. Multiple rotating shafts 806 are fixedly connected to the outside of the rotating rod 805. A stirring blade 807 is fixedly connected to one end of each of the multiple rotating shafts 806. A wiping plate 808 is fixedly connected to one end of each of the multiple stirring blades 807.

[0038] Specifically, the stirring assembly of the sample processing mechanism 8 is supported by multiple bases 801, which are fixed to the base plate 1. These bases collectively support the stirring tank 802, a cylindrical sealed container with a U-shaped plate 803 fixed at the top opening, forming a motor mounting bracket. One end of the sample delivery hose 710 is connected to the inside of the stirring tank 802, allowing the collected sample to fall directly into the tank. A motor 804 is mounted at the bottom of the U-shaped plate 803, with its output shaft vertically connected to a rotating rod 805. As the rotating rod 805 rotates with the motor 804, it drives multiple outer rotating shafts 806 to rotate synchronously. Each rotating shaft 806 has a stirring blade 807 installed at its end, forming a multi-layer stirring structure to thoroughly mix the sample inside the tank. A wiping plate 808 is also fixedly connected to the end of the stirring blade 807. The wiping plate 808 is made of flexible silicone and fits tightly against the inner wall of the stirring tank 802, wiping the tank wall synchronously during stirring to prevent sample adhesion and accumulation, ensuring sample uniformity and processing efficiency.

[0039] The air filtration assembly includes an air filter device 809 fixedly installed on the upper part of the mixing tank 802. An air outlet duct 810 is fixedly connected to the upper part of the air filter device 809, and a miniature fan 811 is provided at one end of the air outlet duct 810.

[0040] Specifically, the air filtration assembly is installed at the top of the mixing tank 802 and consists of an air filter 809, an exhaust duct 810, and a miniature fan 811. The air filter 809 filters the air, absorbs odors, and prevents gas diffusion. The miniature fan 811 is installed at the end of the exhaust duct 810. When running, it creates a slight negative pressure inside the mixing tank 802, causing the air inside the tank to be purified by the air filter 809 and then discharged through the exhaust duct 810. This maintains stable air pressure inside the tank, preventing sample spillage, and ensures the biosafety of the sample processing process through air circulation filtration, avoiding operator exposure to harmful gases.

[0041] The auxiliary components include a heating element 812 fixedly installed on the upper part of a base 801, a heat-conducting pipe 813 provided at one end of the heating element 812, the heat-conducting pipe 813 being wound around the outer wall of the mixing tank 802, a temperature sensor 814 provided on one side of the outer wall of the mixing tank 802, a pressure sensor 815 provided on the other side of the outer wall of the mixing tank 802, and an ultrasonic oscillation device 816 provided at the bottom of the mixing tank 802.

[0042] Specifically, auxiliary components enhance sample processing efficiency. A heating element 812 is fixed to one of the bases 801 and wound around the outer wall of the stirring vessel 802 via a heat-conducting pipe 813, forming a heating circuit for constant temperature control of the sample inside. A temperature sensor 814 is installed on one side of the outer wall of the stirring vessel 802 to monitor the internal temperature in real time and feed it back to the control system for precise adjustment of the heating process. A pressure sensor 815 is installed on the other side to monitor changes in internal pressure, preventing abnormal pressure due to heating or stirring and ensuring safe operation of the device. An ultrasonic oscillation device 816 is also installed at the bottom of the stirring vessel 802. Upon activation, it generates high-frequency vibration, which, in conjunction with the mechanical stirring of the stirring blades 807, accelerates cell lysis or reagent mixing in the sample. This is particularly suitable for scenarios requiring thorough sample disruption, such as nucleic acid extraction, improving the efficiency and effectiveness of pre-detection processing.

[0043] The disinfection component in the cleaning mechanism 9 includes a cleaning box 901 fixedly installed on the other side of the upper part of the base plate 1. A soft rubber ring 902 is provided at the upper inlet of the cleaning box 901, and multiple ultraviolet lamps 903 are provided on the inner wall of the cleaning box 901.

[0044] Specifically, the cleaning box 901 is fixed to the base plate 1, and a soft rubber ring 902 is installed at its upper opening. When the collection head 705 is inserted into the cleaning box 901, the soft rubber ring 902 forms a sealing structure to prevent ultraviolet leakage or disinfectant evaporation during the disinfection process. Multiple ultraviolet lamps 903 are evenly distributed on the inner wall of the cleaning box 901 to sterilize the surface of the collection head 705. During disinfection, the collection head 705 is inserted into the cleaning box 901, and the ultraviolet lamps 903 are activated and continuously irradiate for a certain period of time, ensuring that all parts of the collection head 705 are effectively irradiated, killing residual bacteria, viruses, and other microorganisms, avoiding cross-contamination, and providing clean hardware conditions for subsequent sample collection.

[0045] The cleaning assembly includes a telescopic rod 904 fixedly installed at the bottom of the cleaning box 901. A connecting plate 905 is fixedly connected to the output end of the telescopic rod 904. A motor 906 is fixedly installed on the upper part of the connecting plate 905. A cleaning pad 907 is fixedly connected to the output end of the motor 906.

[0046] Specifically, the cleaning component is installed inside the cleaning box 901, with a telescopic rod 904 fixed at the bottom. Its output end is connected to a connecting plate 905, and a motor 906 is mounted on the connecting plate 905. The output shaft of the motor 906 is connected upwards to a cleaning pad 907, the surface of which can be soaked in cleaning agent. When the collection head 705 is inserted into the cleaning box 901, the telescopic rod 904 rises, causing the cleaning pad 907 to come close to the surface of the collection head 705. The motor 906 drives the cleaning pad 907 to rotate, mechanically wiping the collection hole 706 and outer wall of the collection head 705 to remove attached sample residue or stains. This component works in conjunction with the disinfection component, first removing visible impurities through wiping, then disinfecting with ultraviolet light to improve the cleaning effect and ensure the safe reuse of the collection head 705.

[0047] The heating assembly includes a second heating element 908 disposed on one side of the cleaning box 901, a second heat pipe 909 fixedly connected to the upper part of the second heating element 908, a heat-conducting plate 910 disposed on one side of the outside of the cleaning box 901, and one end of the second heat pipe 909 fixedly connected to the heat-conducting plate 910.

[0048] Specifically, the heating component assists in the disinfection and drying process within the cleaning chamber 901. Heating element 908 is positioned beside the cleaning chamber 901 and connected to the heat-conducting plate 910 on the outer wall of the cleaning chamber 901 via heat pipe 909, forming a heat conduction path. When energized, heating element 908 generates heat, which is conducted through heat pipe 909 to the heat-conducting plate 910 and then evenly distributed into the cleaning chamber 901. This improves the efficiency of ultraviolet disinfection and, after disinfection and wiping, rapidly evaporates moisture from the surface of the sampling head 705 through heating, achieving a drying effect and preventing the growth of microorganisms in a damp environment. Furthermore, a dry sampling head 705 improves the accuracy of subsequent sample collection, preventing moisture from diluting the sample.

[0049] A data acquisition box 10 is also fixedly installed on the other side of the upper part of the base plate 1, and a control display terminal 11 is provided on the upper part of the top plate 4;

[0050] Specifically, a collection box 10 is also set on the other side of the upper part of the base plate 1 to store the samples to be collected. A control display terminal 11 is set on the upper part of the top plate 4, which integrates a touch screen and operation buttons. Operators can start or stop each functional module through the control display terminal 11, and display the device's operating status and fault alarm information, realizing intelligent control of human-machine interaction, ensuring that the entire testing process is automated and visualized, reducing the difficulty of operation, and improving testing efficiency and reliability.

[0051] Working principle: The present invention starts the sample collection mechanism 7 by controlling the display terminal 11. The main rod 702 in the placement platform 701 extends under the push of the telescopic rod 703. The transparent protective cover 704 slides with the main rod 702. The collection hole 706 at the front end of the collection head 705 draws up the sample under the negative pressure generated by the micro vacuum pump 707. The pressure sensor 711 monitors the collection pressure in real time. The sample enters the stirring tank 802 of the sample processing mechanism 8 through the sample delivery hose 710. The chassis 6 supplies power and transmits data to the sample collection mechanism 7 through the connecting cable 709. After the sample enters the mixing tank 802, motor 804 drives the rotating rod 805 to rotate. The rotating shaft 806 on the outside of the rotating rod 805 and the stirring blade 807 stir the sample. The wiping plate 808 on the stirring blade 807 wipes the tank wall simultaneously to prevent the sample from adhering. Heating element 812 heats the mixing tank 802 through heat pipe 813. Temperature sensor 814 monitors the temperature. Ultrasonic oscillation device 816 is activated and works with the stirring to fully lyse the sample. Pressure sensor 815 monitors the pressure inside the tank. Air filtration device 809 filters the gas generated by stirring under the action of micro fan 811 and discharges it through air outlet duct 810. After sample processing, the collection head 705 retracts and enters the cleaning chamber 901 of the cleaning mechanism 9. The soft rubber ring 902 seals the chamber opening, and the ultraviolet lamp 903 disinfects the collection head 705 with ultraviolet light. The telescopic rod 904 pushes the connecting plate 905 upward, and the motor 906 drives the cleaning pad 907 to rotate, wiping the surface of the collection head 705. The heating element 908 heats the cleaning chamber 901 through the heat pipe 909 and the heat plate 910 to assist in disinfection and drying. The disinfected and cleaned collection head 705 can be reused. Throughout the process, the control display terminal 11 displays the operating status of each mechanism and sensor data in real time, ensuring the efficient and safe operation of the detection device. This enables the collection, processing, and equipment cleaning and disinfection of gastrointestinal tumor screening samples, providing reliable support for gastrointestinal tumor screening.
