In a specific scenario, at least two cuvettes 110 may contain the same solution or different solutions, and are not limited herein.
In a specific scenario, different optical paths 200 may detect the same solute of a solution, and may also detect different solutes, which is not limited herein.
As shown in fig. 4, the light path channel 200 includes a light source 210 and a transmitted light collector 220 and/or a scattered light collector 230. The light source 210 is configured to generate a light beam and emit the light beam into the color cell set 100, and the transmission light collector 220 is disposed on a light path of the light beam generated by the light source 210 of the same light path channel 200 and configured to collect transmission light of the light beam after passing through the color cell set 110. The scattered light collector 230 is disposed at a predetermined angle with respect to the optical axis of the light beam, and is configured to collect scattered light of the light beam passing through the color cell stack 100.
Specifically, the detection assembly 300 is coupled to the transmitted light collector 220 and/or the scattered light collector 230.
As shown in fig. 5, each optical channel 200 includes an independent light source 210, and at least two color cells 110 of the color cell set 100 are respectively in one-to-one correspondence with the light beams generated by the light sources 210 of at least two optical channels 200. Similarly, the transmitted light collector 220 and/or the scattered light collector 230 are independent and respectively correspond to at least two colorimetric cells 110.
In another embodiment, a plurality of or all of the at least two light paths 200 may share the light source 210, and the light source 210 may emit a plurality of light beams with different angles to be incident on the at least two colorimetric cells 110, thereby saving the cost and volume of the light source 210.
In other embodiments, the light source 210 and the at least two cuvettes 110 may be connected by optical fibers, so that the light beams of the same light source 210 can be incident on the at least two cuvettes 110.
In a particular embodiment, the color cell stack 100 is at an angle of less than 90 ° to the optical axis of the light beam. Specifically, each cell 110 makes an angle of less than 90 ° with the optical axis of the light beam incident on the cell 110.
In another embodiment, the light-incident sidewall 111 of the cell stack 100 is angled less than 90 ° from the optical axis of the light beam. Specifically, the included angle between the light incident sidewall 111 of each cuvette 110 and the optical axis of the light beam incident to the cuvette 110 may be smaller than 90 °.
The following takes a colorimetric cell 110 and an optical channel 200 as an example:
in one embodiment, as shown in fig. 6, the entire cuvette 110 may be a regular cylinder, and the entire cuvette 110 is disposed at an oblique angle with respect to the optical axis.
In another embodiment, as shown in fig. 7, the light-incident sidewall 111 of the cuvette 110 is inclined with respect to the bottom wall 112 of the cuvette 110, such that the light-incident sidewall 111 is inclined with respect to the optical axis when the cuvette 110 is disposed horizontally with respect to the optical axis.
As shown in fig. 6 and 7, the inclination angle α of the inclination is 1 ° or more and 5 ° or less.
In an exemplary embodiment, the light beam generated by the light source 210 is a concentrated light.
In the above embodiment, the light source 210 generates the light beam as the convergent light, so that most of the light beam entering the colorimetric pool 110 is not vertically incident, and thus the primary reflection of the colorimetric pool 110 on the light beam can be reduced, and further the primary reflection of the colorimetric pool 110 on the light beam can be further reduced by obliquely arranging the optical axes of the colorimetric pool 110 and the light beam, and further the light beam reflected by the colorimetric pool 110 enters the light source 210, so that the loss of the light source 210 is reduced, and the service life of the light source 210 is further prolonged. Furthermore, if the light beam is reflected into the light source 210, the stability of the output power of the light source 210 is directly affected, and the stability of the whole detection result is further affected.
In an embodiment, the optical path 200 may include only the transmitted light collector 220, only the scattered light collector 230, or both the transmitted light collector 220 and the scattered light collector 230.
For embodiments in which both the transmitted light collector 220 and the scattered light collector 230 are included, the detection of the solution in the cuvette 110 typically includes a scattering method and a transmission method, wherein the scattering method is suitable for scenes with low solution concentration and the transmission method is suitable for scenes with high solution concentration.
The transmission concentration value and the scattering concentration value of the solution in the cuvette 110 are respectively obtained through the transmission electric signal generated by the transmission light collector 220 and the scattering electric signal generated by the scattering light collector 230, and are compared with the preset concentration value, if the transmission concentration value and the scattering concentration value are higher than the preset concentration value, that is, the solution can be considered as a high value, the transmission concentration value is adopted as the final detection result. And if the concentration value is lower than the preset concentration value, namely the solution can be considered as a low value, adopting the scattering concentration value as a final detection result.
Therefore, by arranging the transmitted light collector 220 for collecting the transmitted light passing through the cuvette 110 and the scattered light collector 230 for collecting the scattered light passing through the cuvette 110, the transmission concentration value and the transmission concentration value of the solution in the cuvette 110 can be detected, and further the transmission concentration value or the scattering concentration value can be selected as the final detection result according to the detection result, thereby ensuring that the optimal detection result can be ensured no matter the solution is a high-concentration solution or a low-concentration solution.
In a specific embodiment, at least two of the optical paths 200 in the same protein detection apparatus 10 may be the same or different. Are not limited herein.
In a specific scenario, each of the at least two optical paths 200 may include a transmitted light collector 220 and a scattered light collector 230.
In another specific scenario, for at least two optical paths 200 in the same protein detection apparatus 10, one optical path 200 of the at least two optical paths 200 includes both the transmitted light collector 220 and the scattered light collector 230, and one optical path 200 of the at least two optical paths 200 may include only the transmitted light collector 220 or only the scattered light collector 230.
Referring to fig. 8, the optical path channel 200 further includes a first diaphragm 240, the first diaphragm 240 includes a transmission aperture 241, and the transmission aperture 241 is disposed between the cuvette 110 and the transmission light collector 220 and located at the beam waist position of the light beam.
Specifically, after the light beam enters the cuvette 110, a portion of the light beam directly transmits through the cuvette 110 and is transmitted along the original light path, a portion of the light beam is scattered by the solution of the cuvette 110, the collected light path required to be collected by the transmitted light collector 220 is a portion directly transmitting through the cuvette 110 and generating a transmitted electrical signal, and if the stray light scattered by the inner wall of the cuvette 110 is collected by the transmitted light collector 220, the stray light does not carry any signal of the solution of the cuvette 110, the accuracy of the transmitted electrical signal is affected, and the detection result is ultimately affected. According to the invention, the light beams converging light are adopted, the transmission light hole 241 is arranged at the beam waist position of the light beams, and as the part from the light path of the light beams to the beam waist position is gradually narrowed, compared with a parallel light path, the light path is narrowed, which means less stray light can be parallel to the light path, and further, the transmission light hole 241 is arranged at the beam waist position, so that only the light along the light path of the originally converging light beams can pass through the transmission light hole 241 and be collected by the transmission light collector 220, and most of the stray light can be blocked, therefore, the stray light collected by the transmission light collector 220 can be reduced, and the accuracy of the detection result is greatly improved.
In a specific embodiment, the transmission light hole 241 may be a circular light hole, and the diameter of the transmission light hole 241 is equal to the beam waist diameter of the converged light beam.
In other embodiments, the diameter of the transmission light aperture 241 may also be reduced according to the light intensity of the transmission light that needs to be collected by the transmission light collector 220.
In other embodiments, the diameter of the light transmitting hole 241 may be further increased according to assembly tolerance, and the like, which are not limited herein.
As shown in fig. 8, the first diaphragm 240 further includes a scattered light hole 242, the scattered light hole 242 is disposed between the cuvette 110 and the scattered light collector 230, and the scattered light hole is an elliptical light hole. Wherein the major axis of the scattered light aperture is determined by the upper and lower limits of the scattered light that needs to be collected by the scattered light collector 230, and the minor axis of the scattered light aperture is equal to the diameter of the converged light beam when entering the cuvette 110.
The scattered light entering the scattered light collector 230 through the scattered light hole 242 can satisfy a certain angle consistency by arranging the scattered light hole 242, so as to improve the accuracy of the detection result.
As shown in fig. 9, the optical channel 200 further includes a first extinction groove (not shown), a first lens 250, a second extinction groove (not shown), and a second lens 260.
The first extinction groove and the first lens 250 are sequentially arranged between the transmission light hole 241 and the transmission light collector 220, the first extinction groove and the first lens 250 are matched to further eliminate stray light entering the transmission light collector 220, and further, the light spot entering the transmission light collector 220 can be controlled by arranging the first lens 250, so that the size of the light spot can be restricted, and the light spot has better shape and size when being collected by the transmission light collector 220.
The second extinction groove and the second lens 260 are sequentially disposed between the scattered light aperture 242 and the scattered light collector 230, and the second extinction groove and the second lens 260 cooperate to eliminate stray light entering the transmitted light collector 220 and can restrict the size of a light spot, so as to improve the accuracy of a detection result.
As shown in fig. 10, the optical channel 200 further includes a second diaphragm 270 and a third diaphragm 280 sequentially disposed between the light source 210 and the cuvette 110. And the aperture of the second diaphragm 270 is larger than that of the third diaphragm 280.
In a specific embodiment, the aperture of the second diaphragm 270 is greater than or equal to 5mm, less than or equal to 10mm from the light source 210. Specifically, the distance from the light exit hole of the light source 210 is greater than or equal to 5mm, and less than or equal to 10 mm. Specifically, it may be 5mm, 7mm or 10mm, and is not particularly limited herein.
The distance between the light hole of the third diaphragm 280 and the light hole of the second diaphragm 270 is greater than or equal to 30mm and less than or equal to 40 mm; specifically, it may be 30mm, 35mm or 40mm, and is not particularly limited herein. The distance between the aperture of the color comparison pool 100 and the third diaphragm 280 is greater than or equal to 2mm and less than or equal to 5 mm. Specifically, the distance between the light holes of the cuvette 110 and the third diaphragm 280 in the cuvette set 100 is greater than or equal to 2mm and less than or equal to 5 mm. Specifically, it may be 2mm, 4mm or 5mm, and is not particularly limited herein.
Specifically, the converged light beam can be constrained by keeping the aperture of the second diaphragm 270 and the aperture of the third diaphragm 280 consistent with the optical path change of the converged light beam. On the other hand, the stray light generated by the light source 10 itself or the optical cavity between the light source 10 and the third diaphragm 280 can be prevented from entering the cuvette 110, and further, because the aperture of the third diaphragm 280 is small, the influence of the stray light reflected by the cuvette 110 and the transmitted light collector 220 on the light source 10 can be further reduced, so that the light source 10 is protected.
As shown in fig. 11, the light path 200 further includes a base 290, wherein the light source 210, the transmitted light collector 220 and the scattered light collector 230 are disposed on the base 290. In other embodiments, other optical components of the optical path 200, such as the first diaphragm 240, the second diaphragm 270, the third diaphragm 280, the first extinction groove, the first lens 250, the second extinction groove, and the second lens 260, may also be disposed on the substrate 290, which is not limited herein.
As shown in fig. 12, the cell set 100 includes a cell 110, and each optical path channel 200 is used to generate a light beam of one wavelength to be incident on the cell 110 and collect the transmitted and/or scattered light through the cell. And the wavelength of the light beam generated by each of the at least two optical paths 200 is different from the wavelengths of the light beams generated by the other optical paths.
That is, in the specific embodiment, each of the at least two optical paths 200 generates a light beam of one wavelength and the wavelength of the light beam generated by each of the optical paths 200 is different.
Specifically, for the same optical path 200, only the light beam generated by the optical path 200 is collected, and the light beams generated by other optical paths 200 are not collected, and the collection may specifically depend on the identification of the wavelength.
In one embodiment, each of the optical pathways 200 is independent of the other, and the light beams generated by at least two of the optical pathways 200 are incident from different regions of the cuvette 110. I.e., the light beams generated by the respective light path channels 200 are incident from different regions of the cuvette 110.
As shown in fig. 12 and 13, the optical path 200 includes a light source 210 and a transmitted light collector 220 and/or a scattered light collector 230. The light sources 210 of the multiple light paths 200 generate light beams with one wavelength to be incident on the same cuvette 110, and since the wavelengths of the light beams generated by each light source 210 are different, the transmitted light collector 220 and/or the scattered light collector 230 can selectively collect light beams according to the wavelengths, so as to collect only the light beams generated by the light sources 210 of the light paths 200.
As shown in fig. 12, in an embodiment, the number of the optical path channels 200 may be three, the three optical path channels 200 are arranged in an array, and specifically include three light sources 210, three light beams generated by the three light sources 210 are incident from different areas of the cuvette 110, three transmission light collectors 220 are respectively and correspondingly arranged on the optical paths of the light beams generated by the three light sources 210 and are respectively used for collecting the transmission light of the light beams generated by the corresponding light sources 210 via the cuvette 110, and three scattered light collectors 230 are also respectively and correspondingly arranged and are respectively used for collecting the scattered light of the light beams generated by the light sources 210 via the cuvette 110.
In a specific embodiment, filters may be disposed in front of the collection channels of the transmission light collector 220 and the scattered light collector 230, so that the transmission light collector 220 and the scattered light collector 230 only collect light beams with corresponding wavelengths.
In another embodiment, the at least two optical pathways 200 may share a light source 210, and the light source 210 may be configured to emit light beams of different wavelengths from different regions of the cuvette 110 by means of optical fibers or the like.
In another embodiment, the at least two optical pathways 200 may share the light source 210, and the light source 210 may generate a light beam incident into the cuvette 110, and the light beam may include light of multiple wavelengths.
In a specific scenario, as shown in fig. 14, the two optical pathways 200 share a light source 210 and produce a light beam containing two wavelengths that is incident on the cuvette 110. The two transmissive light collectors 220 may be disposed on the light path of the light beam corresponding to each wavelength, and specifically, the first selective transflective film 221 may be disposed between the two transmissive light collectors 220 of the color cell 110 to filter or reflect light with different wavelengths. Specifically, the first selective transflective film 221 may be disposed at a predetermined angle with respect to an optical axis of the light beam, when the transmitted light of two wavelengths passes through the first selective transflective film 221, the transmitted light of one wavelength may be reflected to enter another optical path, the corresponding transmitted light collector 220 may be disposed on the optical path to collect the transmitted light of the wavelength, and the transmitted light of another intermediate wavelength may directly pass through the first selective transflective film 221 to be transmitted along the original optical path and collected by the transmitted light collector 220 disposed on the optical path. Similarly, the scattered light collector 230 can collect the scattered light with corresponding wavelength by disposing a second selective transflective film 231 between the two scattered light collectors 230 and the cuvette 110.
By the above method, the number of the light sources 210 and the volume requirement of the cuvette 110 can be reduced, and further, the volume and the cost of the whole device can be reduced.
In a particular embodiment, the light beams generated by the at least two light paths 200 are incident on the cuvette 110 independently or simultaneously. That is, only one light beam generated by one optical path 200 may be used for detecting the color cell 110, or a plurality of optical paths 200 may generate light beams with various wavelengths and detect the color cell 110 at the same time.
In a specific scenario, the detection of the solution may specifically be detection of a solute in the solution, such as a protein or other solutes, and for different solutes, the sensitivities of the light beams with different wavelengths are different, so that when a certain solute needs to be detected, the light beam with the optimal wavelength may be selected to detect the colorimetric pool 110, thereby improving the detection effect. Furthermore, the light beams with different wavelengths are adopted to detect the color pool 110, and the light beams with different wavelengths do not interfere with each other, so that the solution in the color pool 110 can be simultaneously detected for multiple solutes without being detected one by one, and the detection speed can be greatly increased.
A description of a specific scenario is made with respect to the overall structure of the blood cell analyzer 1:
the control and information processing module 20 controls the reagent collecting and distributing device 30 to collect the solution and distribute the collected solution, which may be specifically distributed to each cuvette 110 in the cuvette set 100 of the protein detecting device 10. The light source 210 emits a converged light beam, the converged light beam sequentially passes through the second diaphragm 270 and the third diaphragm 280, the second diaphragm 270 and the third diaphragm 280 restrict the converged light beam through respective light holes, so that the converged light beam is incident into the cuvette 110 according to a required cross-sectional size, because the cuvette 110 has a certain inclination with the optical axis of the converged light beam, the converged light beam is not easily reflected back to the light source 210 along the original path, and part of the light beam reflected toward the light source 210 is blocked by the second diaphragm 270 and the third diaphragm 280, so as to protect the light source 210, the part of the converged light beam incident into the cuvette 100 is scattered due to the inner wall of the cuvette 100 to form stray light, part of the light beam directly transmits through the cuvette 100 to form transmitted light, and part of the light beam forms scattered light due to the influence of a solution in the cuvette 100.
The transmitted light sequentially passes through the transmission aperture 241 of the first diaphragm 240, the first extinction groove and the first lens 250 and is collected by the transmitted light collector 220, specifically, on one hand, since the light path of the converged light beam is gradually narrowed in the propagation process, stray light and scattered light parallel to the converged light beam can be reduced, and further, the transmission aperture 241 is arranged at the beam waist position of the converged light beam to ensure that only the light beam coincident with the light path of the converged light beam can penetrate through the transmission aperture 241, then, the stray light entering the transmitted light collector 220 is further eliminated through the cooperation of the first extinction groove and the first lens 250, and the light beam is constrained by the first lens 250, so that the transmitted light collector 220 has a better shape and size when being collected. In the above-mentioned structure, on the one hand can reduce the light beam and reflect back to light source 210 to protect light source 210, improve the stability of the light beam that assembles that light source 210 launches, and then improve detection effect, on the other hand is through handling stray light etc. to reduce stray light etc. and enter into transmission light collector 300, thereby reduce the influence of stray light to the detection, thereby improve detection effect.
The scattered light sequentially passes through the scattered light aperture 242, the second extinction groove and the second lens 260 of the first diaphragm 240 and is collected by the scattered light collector 230, the angle consistency of the scattered light entering the scattered light collector 230 can be ensured through the scattered light aperture 242, the stray light is reduced through the second extinction groove and the second lens 260, and therefore the whole detection effect can be improved.
In a specific embodiment, in the case that the protein detection apparatus 10 includes a plurality of optical paths 200, each of the plurality of optical paths 200 may operate according to the above-mentioned scenario, or may operate differently from the above-mentioned scenario, but the specific operation principle is similar, and is specifically determined according to the type of the component.
In summary, the invention provides a blood cell analyzer, which can detect one or more kinds of solution information of one or more groups of solutions by arranging a plurality of light path channels in a protein detection device of the blood cell analyzer, thereby greatly improving the detection efficiency; on one hand, the light beam is set to be convergent light, a certain inclination angle is arranged between the colorimetric pool group and the optical axis of the light beam, and the second diaphragm and the third diaphragm are further arranged, so that the light beam cannot be reflected on the original path to damage the light source when entering the colorimetric pool, and the service life of the light source is prolonged; on one hand, the first diaphragm is arranged, and the transmission light hole of the first diaphragm is arranged at the beam waist position of the light beam, so that the influence of stray light on the transmission light collector is reduced, and the detection precision is improved; on the one hand, the light beams generated by the light path channels are set to different wavelengths, so that the light path channels can be detected by the same colorimetric pool, and the detection rate is increased.
