Description
Affiliated technical field
The invention belongs to homogeneous luminescent technical field of immunoassay, be specifically related to a kind of high speed light path switching mechanism.
Background technology
Homogeneous luminescent immunoassay technology is that of getting up of development in recent years is intended to replace existing enzyme mark technology, have efficient, high precision, high reliability, the brand-new clinical detection means of the series of advantages such as low cost.The utilization of homogeneous luminescent immunological technique is carried out the detection of biomolecule as the microballon of donor and acceptor.Wherein, donor microballon is filled with photosensitizer, and acceptor microballon is filled with chemiluminescence agent, if there is biomolecule to be measured in sample, donor microballon and acceptor microballon can be close to each other due to the specific binding of antibody antigen, thus form bridge couplings donor, be subject to attachment structure.After Stimulated Light excites, free oxygen transmits in bridge architecture, then produces the light signal of 615nm.Based on above principle, the core of homogeneous luminescent immune detection instrument is by photon counter, and semiconductor laser and high speed light path switching mechanism form.
Because sample produces flashlight after by laser excitation within very short time, and signal light intensity declines in time according to exponential law.Again due to the vulnerability of the high sensitivity of photon counter and target surface, during laser is to sample irradiation, any laser leaks into photon counter passage and all may cause detecting and unsuccessfully even damage expensive photon counter, has greatly reduced system signal noise ratio.Therefore, reasonably high speed light path switching mechanism is the key of system.
Existing light path switching mechanism is made up of optical shutter and sample carrier travel mechanism.Detecting point 4 steps completes: 1) sample cell is moved on to laser instrument below by travel mechanism, opens laser instrument sample cell is irradiated.During this period, optical shutter is closed, and stops photon to enter photon counter passage.2) Ear Mucosa Treated by He Ne Laser Irradiation finishes, and closes laser instrument.3) travel mechanism moves on to sample cell photon counter below at once, opens optical shutter and carries out photon counting.4) counted, closed optical shutter.
In the detecting step (1) of existing light path switching mechanism, be subject to the restriction of stepper motor-mechanical guide rail slide block structure its switching time, be difficult to the distance of tens millimeters of moving within a few tens of milliseconds, thereby miss optimum detection opportunity, reduce the sensitivity of system.Simultaneously, owing to being subject to the restriction of physical construction and material, the design of individual layer optical shutter is difficult to stop completely the scattered light of laser or external light source, and the scattered light of its infiltration will be leaked to photon counter passage, cause " dark counting " and ground unrest to raise, reduce the signal to noise ratio (S/N ratio) of system.
In the detecting step (3) of existing light path switching construction, another shortcoming of this mechanism is that optical shutter and travel mechanism are indispensable.In the occasion that does not need sample cell to move, as single-point device for fast detecting, the travel mechanism that only plays light path switching effect makes system complex, and cost increases.
In existing homogeneous luminescent immunity analysis instrument, LASER Light Source, light path switching mechanism, flashlight collection, photon counter all adopt Split type structure, be relatively independent between these four parts, cause whole instrument system complex structure, collaborative work Efficiency Decreasing, greatly increase instrument holistic cost, safeguarded and comparatively difficulty of upgrading.
Summary of the invention

Embodiment
The present invention is a kind of high speed light path switching mechanism, comprises photon counter (1), fixed support (2), rotating disc (3) and laser instrument (7) etc.Photon counter (1) is arranged on fixed support (2).On fixed support (2), have the flashlight collection channel (11) concentric with photon counter target surface.Sample cell (10) is placed in the below of rotating disc (3) the position concentric with flashlight collection channel (11).The rotation center of rotating disc (3) and flashlight collection channel (11) center are set for the eccentric.Right-angle prism (6) for reflection lasering beam is installed respectively on the diameter that rotating disc (3) overlaps with flashlight collection channel (11) and for collecting the lens (5) of flashlight, sees accompanying drawing 1.
Comprise photon counter (1), laser instrument (7), rotating disc (3), it is upper that flashlight sampler is all integrated in fixed support (2) at interior crucial subassembly, makes it to become a high speed light path switching mechanism independently.This individual cores assembly is the design of homogeneous luminescent immune detection system, produces, and maintenance, remodeling brings great convenience.
The combination end face of fixed support (2) and rotating disc (3) is concentric annular optics labyrinth structure.In this structure, be provided with multinest formula protuberance and groove structure in fixed support (2) below and rotating disc (3) top, the mutual close-coupled of protuberance and groove also can freely be rotated, thereby forms multilayer barrier labyrinth structure.See accompanying drawing 2, Δ is enough little, and scattered light need to experience and reflect many times the surface that could arrive photon counter.The surface reflectivity in optics labyrinth is enough low, and the scattered light intensity of multiple reflections declines with the form of index, and the photon number that arrives photon counter target surface can be lower than the background noise sound of photon counter itself.
Referring to accompanying drawing 1, the principle of work of high speed light path switching mechanism is: (1) is at laser excitation station, rotating disc (3) rotates to right-angle prism (6) sample cell (10) top under stepper motor drives, and the light beam (8) that laser instrument (7) sends is done after 90 degree turn to be radiated at sample cell through right-angle prism (6).Because right-angle prism (6) does not communicate with flashlight collection channel (11) at the fixing position of rotating disc (3), flashlight collecting lens (5) is also rotated to the angle not communicating with flashlight collection channel (11), add the catadioptric absorption function in concentric annular optics labyrinth, the scattered light that irradiates sample can not drain to the collection channel of photon counter.Low-down system " dark counting " value and background noisiness are ensured.(2), at input station, rotating disc (3) rotates to flashlight collecting lens (5) sample cell (10) top under stepper motor drives.Now, sample cell (10), flashlight collecting lens (5), flashlight collection channel (11), flashlight collecting lens (4) and photon counter target surface are concentric, and photon counting passage is opened.
Because the moment of inertia of rotating disc (3) can design much smaller than the translation inertia of sample cell movable support bracket, light path is switched and can within a few tens of milliseconds, be completed.
Further set forth integrated high speed light path switching mechanism below in conjunction with experimental data and ensureing, on the basis of low noise, low stray light, can also to obtain higher detection sensitivity.
