Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a portable testing instrument for diagnosing infectious diseases. Background Technology

[0002] Infectious diseases are caused by pathogens and can be transmitted between people, animals, or between humans and animals.

[0003] Portable diagnostic instruments for infectious diseases are innovative medical devices that integrate microfluidics, biosensing, and molecular diagnostic technologies. They are characterized by portability, speed, and accuracy. These devices typically use microfluidic biochips or lateral chromatography technology, combined with portable PCR instruments or quantitative fluorescence analysis, to achieve rapid detection of pathogen nucleic acids or antigens.

[0004] Existing diagnostic instruments cannot simultaneously test for different pathogens when checking pathogen concentrations, requiring doctors to perform multiple tests sequentially. This not only prolongs diagnosis time but also increases patient anxiety. Furthermore, single-pathogen testing can easily overlook other potential infectious factors, especially when patients are infected with multiple pathogens simultaneously or when symptoms are caused by the combined effects of multiple pathogens. These limitations may lead to incorrect treatment decisions and contribute to antibiotic overuse and drug resistance. Therefore, this paper proposes a portable diagnostic instrument for infectious diseases to overcome these shortcomings. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable diagnostic instrument for infectious diseases.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a portable diagnostic instrument for infectious diseases, comprising a housing, a base frame slidably connected to the front end of the housing, a cabinet door fixedly connected to the front upper end of the base frame, a test tube rack fixedly connected to the rear end of the cabinet door, a laser diode fixedly connected inside the housing, a light sensor disposed at the right end of the laser diode, an interferometric biosensor fixedly connected to the upper end of the housing, a collection box slidably connected to the bottom front end of the housing, ultraviolet lamps fixedly connected to the left and right ends of the housing, a modification liquid tank fixedly connected to the rear end of the housing, micro water pumps fixedly connected to the left and right sides of the modification liquid tank, a drive motor fixedly connected to the rear end of the housing, a bracket fixedly connected to the output end of the drive motor, a nozzle fixedly connected to the lower end of the bracket, a battery fixedly connected to the right side of the housing, and a controller fixedly connected to the right side of the front end of the housing.

[0007] As a further description of the above technical solution: the left and right ends of the test tube rack are slidably connected to the inside of the shell, and the outer side of the cabinet door is fitted to the inside of the shell, so that the test tube rack can be pulled out through the cabinet door, making it convenient for staff to place the test tubes.

[0008] As a further description of the above technical solution: the controller is connected to the light sensor via a wire and controls the opening and closing of the nozzle. The light sensor accurately identifies and adds the modifying solution to the test tube containing the pathogen.

[0009] As a further description of the above technical solution: three horizontally arranged square grooves are provided inside the front end of the housing, and the shape and size of the cross-section of the square grooves are matched with the shape and size of the cross-section of the cabinet door, so that the device can simultaneously perform dripping inspection of different modifying liquids through the three horizontally arranged square grooves, thereby improving inspection efficiency.

[0010] As a further description of the above technical solution: the square groove at the front end of the housing is provided with a positioning groove at the rear end, and the drive motor is located in the positioning groove. By placing the drive motor in the positioning groove, the drive motor is prevented from blocking the light emitted by the laser diode.

[0011] As a further description of the above technical solution: the upper end of the base frame is provided with a through circular groove, and the diameter of the circular groove gradually decreases from top to bottom. The maximum diameter of the through circular groove at the upper end of the base frame matches the diameter of the test tube, so that the light emitted by the laser diode can irradiate the test tube through the through circular groove at the upper end of the base frame.

[0012] As a further description of the above technical solution: the rear end of the shell has three horizontally arranged hollow structures, and the micro water pump and the drive motor are located inside the hollow structures. Different modification liquids in the tank are dripped into the test tube through the nozzle, so that the device can conduct different pathogen detection experiments at the same time, thereby improving work efficiency.

[0013] This utility model has the following beneficial effects:

[0014] This invention relates to a portable diagnostic instrument for infectious diseases. Through the design of the collection box and the drive motor, patients can obtain information on multiple pathogen infections with just one sample, avoiding the anxiety of multiple waiting times. Especially in emergency situations, it can quickly identify the cause of the disease, improve diagnostic efficiency, and comprehensively screen potential infection factors to reduce the risk of missed or misdiagnosed cases. It also assists doctors in precise medication, reduces antibiotic overuse, optimizes the allocation of medical resources, reduces equipment usage and staff workload, and lowers the cost of repeated testing.

The light sensor 6 accurately identifies and adds the modification solution to the test tube containing the pathogen.

[0028] As a further implementation of the above technical solution: three horizontally arranged square grooves are provided inside the front end of the housing 1, and the shape and size of the cross-section of the square grooves are matched with the shape and size of the cross-section of the cabinet door 3, so that the device can simultaneously perform dripping inspection of different modifying liquids through the three horizontally arranged square grooves, thereby improving inspection efficiency.

[0029] As a further implementation of the above technical solution: the front end of the housing 1 has a square groove and the rear end has a positioning groove, and the drive motor 12 is located in the positioning groove. By placing the drive motor 12 in the positioning groove, the drive motor 12 is prevented from blocking the light emitted by the laser diode 5.

[0030] As a further implementation of the above technical solution: a through circular groove is provided at the upper end of the base frame 2, and the diameter of the circular groove gradually decreases from top to bottom. The maximum diameter of the through circular groove at the upper end of the base frame 2 matches the diameter of the test tube, so that the light emitted by the laser diode 5 can be irradiated into the test tube through the through circular groove at the upper end of the base frame 2.

After inactivation, the light sensor 6 detects the test tubes on the test tube rack 4 through changes in light, then start the drive motor 12, which drives the support 13 to move downwards, and the support 13 drives the nozzle 14 to move closer to the test tube opening to avoid splashing of the modification liquid due to gravity, which would affect the experimental results. Start the micro water pump 11. Pump 11 draws modification solution from modification solution tank 10 to nozzle 14. Simultaneously, controller 16 controls nozzle 14 to turn on, adding modification solution to the designated test tube. After adding modification solution, motor 12 drives support 13 to reset. Then, laser diode 5 is activated, passing through a circular groove at the lower end of base 2 to irradiate the surface of the test tube. Interferometric biosensor 7 detects data such as wavelength shift and light intensity change in the test tube, thereby detecting pathogen concentration. Finally, interferometric biosensor 7 transmits the data to controller 16 for data analysis by medical personnel. Battery 15 provides power to the device, supporting its mobile use.
