Description

Hand-held type fluorescence immunoassay appearance

Technical Field

The utility model belongs to the technical field of medical instrument, a hand-held type fluorescence immunoassay appearance is related to.

Background

POCT, point-of-care testing (point-of-care testing), a testing method that is performed at the sampling site and uses a hand-held analyzer and a kit to quickly obtain a test result, a test that is performed at the patient's side in space, namely "point-of-care testing"; in time, the system can carry out 'real-time inspection', is a rapid detection and analysis technology carried out close to a patient, has the advantages of meeting the requirements of doctors and patients on the time of examination reports, being simple and convenient to operate, and being capable of being completed by clinicians, nurses, even patients or family members.

The detection principle of the fluorescence immunoassay analyzer is based on an immunofluorescence detection method designed on the immunofluorescence technology, the chromatography technology and the fluorescence induction technology. Using fluorescein as a marker, binding with a known antibody or antigen, and then using the fluorescently labeled antibody or antigen as a standard reagent. And (3) taking the test solution as a mobile phase, moving the object to be tested on the reagent strip through capillary action, carrying out specific immunoreaction on the object to be tested at the T line, carrying out immunoreaction the free object at the C line, and testing the concentration of the object to be tested by a competition method and a sandwich method of an immunochromatography method. Firstly, a semiconductor/laser light source emits emission light with a specific wavelength to irradiate a sample, fluorescence with a certain wavelength is excited, the intensity of the fluorescence is received by a photosensitive diode, and a photoelectric signal is converted into a voltage signal. The concentration value of the measured object is in positive correlation with the fluorescence intensity, and the concentration and the content of the measured object are measured according to the concentration value and the fluorescence intensity. At present, the main immunochromatographic techniques include fluorescence immunochromatographic assay and colloidal gold chromatography, wherein the fluorescence immunochromatographic assay rapid detection technology can be widely applied to on-site quantitative detection, so that the fluorescence immunochromatographic assay rapid detection technology is an important direction for the development of the future instant detection technology.

The handheld fluorescence immunoassay analyzer is clinically pursued due to the advantages of small volume, convenience in carrying, simplicity in operation, high speed, good stability, high sensitivity, low cost and the like, and the application scene is also expanded from the initial clinical application scenes (120 ambulances, social health centers, home contracted doctors for home inspection, rural health hospitals, ICU outpatient emergency treatment) and the like to the food sanitation application scenes, the environmental monitoring application scenes, the drug inhibition application scenes, the forensic medicine application scenes and the like, so that the handheld fluorescence immunoassay analyzer becomes the POCT analyzer which is the fastest in recent development.

The prior handheld fluorescence immunoassay analyzer has two technical routes in the prior art, the first is realized by adopting a technical route of directly acquiring fluorescence intensity by a photosensitive diode and converting an optical signal into an electric signal, and the second is realized by adopting a technical route of taking a picture of emitted fluorescence by a camera and then carrying out algorithm processing on the acquired fluorescence image signal. The technical route mode of adopting the photosensitive diode is the implementation mode with the most mature technology and the most wide application; although the mode of adopting the technical route of taking pictures by the camera can omit a motion transmission mechanism so as to ensure that the volume can be smaller; however, the photographing technical route needs to adopt hardware configurations such as a special and high-cost camera and a CPU with high calculation capability to perform image processing, so that the overall cost is higher than that of the photodiode technical route.

However, the handheld fluorescence immunoassay analyzer implemented by the prior art aiming at the photodiode technical route mainly has the following defects:

1. in the prior art, the analysis and detection of a multi-connected reagent card cannot be realized in the space with the same volume and size; because the design of optical components, code scanning modules, the design of motion mechanisms, the structural design of the whole machine and the like cannot realize compact and miniaturized design, the detection of a multi-connected card cannot be realized by realizing a two-dimensional motion mechanism under a handheld instrument in the prior art.

2. In the prior art, the two-dimensional code/bar code of the reagent card is identified in advance outside the machine, but the two-dimensional code or bar code of the reagent card cannot be identified and read inside the machine, and then the reagent card is inserted into the machine for detection; therefore, the experience of the user is greatly reduced, the detection operation becomes complicated, and the advantage of simple operation of the POCT instrument is just reduced.

3. In the prior art, the portable cloud data platform has the advantages of single function, large volume, difficulty in carrying, complex operation, incompact component layout and structural design, incapability of directly printing detection results, incapability of timely transmitting data to the cloud data platform to prevent loss and the like.
