Description

Technical Field

[0001] The present invention belongs to the field of medical detection, and in particular relates to a detection component, a detection analyzer and a detection and analysis method. Background Art

[0002] Detection analyzers are widely used in the field of medical testing. For example, the dry biochemical analyzer currently on the market is a commonly used detection analyzer. Its main working principle is:

[0003] A dry sheet with fixed reagents is used as a carrier, and test samples such as whole blood, plasma or serum are added to the dry sheet. The water in the test sample is used as a solvent, and a color reaction occurs between the test sample and the reagent. The test light source is then irradiated onto the dry sheet, and the dry sheet that produces the color reaction is sensed by the sensing element, and various biochemical indicators of the test sample are obtained through the colorimetric principle.

[0004] During the detection process, the accuracy of the final test results may be affected by changes in the parameters of the detection light source or sensing element due to repeated use, or by changes in environmental factors. Existing practices are to calibrate the detection analyzer using calibration components (such as white matter) to improve detection accuracy.

[0005] The existing practice is that when maintaining the equipment, professional personnel calibrate the detection analyzer using calibration components.

[0139] Heating assembly 1300 and related components

[0140] Please focus on Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 , and combined with other views, a third guide rail 2420 is provided on the middle partition 3330, and the heating component 1300 is movably installed on the middle partition 3330 through the third guide rail 2420. A slider 2460 is provided on the third guide rail 2420, and the slider 2460 is fixedly connected to the driving block 2430. The heating component 1300 is fixed on the driving block 2430; a guide groove 2450 is provided on the driving block 2430, and a third driving motor 241 is provided on the base frame 3300. 0, the output shaft of the third drive motor 2410 is connected to the cam 2440, and the cam 2440 cooperates with the guide groove 2450. When the third drive motor 2410 rotates, it drives the cam 2440 to rotate, and the cam 2440 cooperates with the guide groove 2450 and drives the drive block 2430 to move up and down, thereby driving the heating component 1300 to move up and down, so that the heating component 1300 is pressed against the detection area of ​​the detection support seat 1200 or separated from the detection area of ​​the detection support seat 1200.

[0141] The heating assembly 1300 further includes a heating body upper shell 1350, a heating body lower shell 1360, a second heating element 1310, a heat conductive block 1320, a pressure head 1330 and a second elastic member 1340. The second heating element 1310 is a diaphragm structure. The heating body upper shell 1350 and the heating body lower shell 1360 cover each other to form a heating space. The second heating element 1310 and the heat conductive block 1320 are both located in the heating space and in contact with the heat conductive block 1320. A first through hole 1320 is provided on the heat conductive block 1320. 1. A second through-hole 1361 corresponding to the first through-hole 1321 is provided on the lower shell 1360 of the heating body. A slot 1322 is provided on the heat conductive block 1320. The first through-hole 1321 is located below the slot 1322. The rear end of the second elastic member 1340 is located within the slot 1322. A pressure strip 1323 is provided within the slot 1322 to press the rear end of the second elastic member 1340. The second heating element 1310 is mounted on the back side of the heat conductive block 1320 and covers the pressure strip 1323.

The front end of the pressing head 1330 faces the detection support 1200, and each pressing head 1330 corresponds to the detection hole 1211 of the detection support 1200. In this embodiment, there are two pressing heads 1330 and two second elastic members 1340 corresponding to each detection hole 1211 . During detection, the two pressing heads press against two sides of the detection hole 1211 respectively.

[0142] The heat conductive block 1320 is heated by the second heating element 1310 to control the temperature of the heating component 1300. During detection or calibration, the temperature of the detection sample on the detection component 1000 is precisely controlled by the second heating element 1310 of the heating component 1300 and the first heating element of the detection component 1000 (the first heating element will be described later), thereby obtaining accurate detection results during detection or calibration.

[0143] The heating assembly 1300 includes a heating body upper shell 1350 and a heating body lower shell 1360, which can provide the heating assembly 1300 with a relatively sealed space, reduce heat loss of the second heating element 1310, make the temperature control of the heating assembly 1300 more precise, and reduce energy consumption.

[0144] A pressure head 1330 is provided on the front side of the heating component 1300. The second elastic member 1340 acts on the pressure head 1330. During testing or calibration, the pressure head 1330 is pressed against the test sample and the position of the pressure head 1330 can be adjusted autonomously according to the thickness of the test strip (and the test sample). The position of the pressure head 1330 can be adaptively adjusted, and can be suitable for test strips of different thicknesses.

[0145] A groove 1322 is provided on the heat conductive block 1320, and a pressure strip 1323 is provided in the groove 1322. The second elastic member 1340 is pressed by the pressure strip 1323 to prevent the second elastic member 1340 from being repeatedly stressed and damaging the second heating element 1310 of the diaphragm structure. The second elastic element is restricted in the groove 1322 by the pressure strip 1323, so that multiple second elastic elements can be more stably limited.

[0146] Detection component 1000

[0147] Please focus on Figures 9 to 25 , and combined with other views, the detection assembly 1000 is the main component of the detection analyzer, which includes a calibration component fixing seat 1100, a detection support seat 1200, and a support base 1500. The support base 1500 includes a base base 1510, on which a detection light source 1660 and a sensing element 1651 are provided. A detection area is provided on the detection support seat 1200, and a calibration area is provided on the calibration component fixing seat 1100; the calibration component fixing seat 1100 is used to install the calibration component 4000 (in this embodiment, the calibration component 400 0 uses white matter, which serves as a standard reflective material during calibration); the detection support seat 1200 is used to place the detection sample for detection; the support base 1500 is provided with a detection light source 1660. During calibration, the light emitted by the detection light source 1660 is irradiated onto the calibration component 4000. During detection, the light emitted by the detection light source 1660 is irradiated onto the detection sample in the detection area. The reflected light of the calibration component 4000 or the detection area is sensed by the sensing element 1651, and then the data during calibration or detection is obtained for analysis and processing.

[0148] Please focus on Figures 9 to 14 , and combined with other views, the detection support seat 1200 is fixedly connected to the support base 1500 to form a detection fixed seat, and a sliding space is formed inside the detection support seat 1200, and the calibration piece fixed seat 1100 is movably arranged in the sliding space, and a first driving device 2100 is provided between the support base 1500 and the calibration piece fixed seat 1100; the calibration piece fixed seat 1100 has a calibration position and a detection position under the action of the first driving device 2100. When in the calibration position, the calibration piece fixed seat 1100 moves forward, and the detection light source 1660 and the sensing element 1651 are opposite to the calibration area on the calibration piece fixed seat 1100. When in the detection position, the calibration piece fixed seat 1100 moves backward, and the detection light source 1660 and the sensing element 1651 are opposite to the detection area on the detection support seat 1200.

[0149] When in use, the calibration component 4000 is installed on the calibration component fixing seat 1100, the detection support seat 1200 is fixedly connected to the support base 1500 and a sliding space is formed between the two. The calibration component fixing seat 1100 is movably arranged in the sliding space and is driven to move by the first driving device 2100. When calibration is required, the calibration component fixing seat 1100 moves forward, the detection light source 1660 and the sensing element 1651 are both opposite to the calibration area on the calibration component fixing seat 1100, and the light emitted by the detection light source 1660 is irradiated to the calibration component 4000. On the top, the sensing element 1651 senses the light reflected from the calibration component 4000 and obtains the calibration signal of the detection analyzer in the calibration state. When detection is required, the calibration component fixing seat 1100 moves backward, and the detection light source 1660 and the sensing element 1651 are opposite to the test strip on the detection support seat 1200. The light emitted by the detection light source 1660 is irradiated on the test strip, and the sensing element 1651 senses the light reflected from the test strip and obtains the detection signal of the detection analyzer in the detection state. By processing the calibration signal and the detection signal, a relatively ideal actual measurement result can be obtained. Since the calibration component fixing seat 1100 is slidably set in the sliding space, under the action of the first drive, the detection analyzer can be conveniently calibrated. The calibration is very convenient. The user can calibrate every time the device is turned on, or before or after each detection, thereby improving the accuracy of the detection.

[0150] A first elastic member 2200 is provided between the first driving device 2100 and the calibration member fixing seat 1100, and its specific structure is as follows:

[0151] The first elastic member 2200 includes: a sleeve 2210, a first spring 2220, and a push rod 2230. The sleeve 2210 is hollow and has a sliding hole at its front end. The rear end of the push rod 2230 has an expansion limit head 2231. The expansion limit head 2231 is located in the sleeve 2210 and its rear end is pressed by the first spring 2220. The front end of the push rod 2230 extends through the sliding hole. The front end of the sleeve 2210 is provided with a first limit portion 2211 (i.e., a limit flange). An action groove 1113 is provided on the calibration part fixing seat 1100, a pressing portion 1114 is provided on the front side of the action groove 1113, and a second limiting portion 1115 (i.e., two limiting vertical surfaces on the rear side of the action groove 1113) is provided on the rear side of the action groove 1113. The front end of the sleeve 2210 extends into the action groove 1113, and its first limiting portion 2211 is limited by the second limiting portion 1115, and the end of the front end of the push rod 2230 faces the pressing portion 1114. The circumferential surface of the output shaft 2110 of the first driving device 2100 has an axial clamping strip 2141, and the end of the output shaft 2110 has a shaft neck 2142. The rear end circumference of the sleeve 2210 is provided with a bayonet 2212, and the bayonet 2212 of the sleeve 2210 is clamped on the clamping strip 2141. A fixing screw 2213 is provided on the sleeve 2210, and the fixing screw 2213 is clamped on the shaft neck 2142 of the output shaft 2110 to realize the connection between the sleeve 2210 and the output shaft 2110 of the first driving device 2100.

[0152] The bayonet 2212 of the sleeve 2210 is engaged with the output shaft 2110 of the first drive device 2100, and the fixing screw 2213 passes through the sleeve 2210 and is engaged with the journal 2142 of the output shaft 2110. The first drive device 2100 drives the sleeve 2210 forward or backward via its output shaft 2110. When the sleeve 2210 moves forward, the front end of the push rod 2230 abuts against the pressing portion 1114, pushing the calibration component holder 1100 forward, aligning the calibration hole 1130 with the detection light source 1660 and the sensing element 1651. When the sleeve 2210 moves backward, the first limiting portion 2211 on the sleeve 2210 drags the second limiting portion 1115 on the calibration component holder 1100, thereby driving the calibration component holder 1100 backward, aligning the detection hole 1211 with the detection light source 1660 and the sensing element 1651. Due to the provision of the first spring 2220 , when the sleeve 2210 moves forward to its proper position, the first spring 2220 can buffer the first driving device 2100 .

[0153] A positioning platform (a first positioning platform 1513 located in the middle and two second positioning platforms 1514 located at the side) is provided on the support base 1500. When in the calibration position, the calibration component fixing seat 1100 moves forward and presses against the positioning platform. When the sleeve 2210 moves forward into position, the calibration component fixing seat 1100 is accurately limited by the first positioning platform 1513 and the second positioning platform 1514 (high-precision hard positioning), so that the calibration component 4000 is accurately aligned with the detection light source 1660 and the sensing element 1651, and the calibration is completed. The accuracy of the calibration is greatly improved; on the other hand, the processing accuracy of the first positioning platform 1513 and the second positioning platform 1514 is also relatively high. In order to avoid impact caused by multiple movements and affect the positioning accuracy of the calibration component fixing seat 1100, the first spring 2220 is set to have a good buffering effect. One side of the calibration component fixing seat 1100 adopts higher-precision positioning, and the other side adopts an elastic adaptive structure (soft positioning). The clever combination of the two improves the positioning accuracy while reducing the manufacturing requirements for the mechanism itself.

[0154] Please focus on Figure 9 、 Figure 10 、 Figure 15 and Figure 16 , and in combination with other views, the detection support base 1200 includes a detection base base 1210, and two groups of positioning structures are provided on the detection base base 1210 to position the test strip, namely: a first positioning portion and a second positioning portion; the first positioning portion corresponds to the entire detection area, and when the linked card test strip 5000 is placed, it is positioned by the first positioning portion to prevent the linked card test strip 5000 from displacement; six detection holes 1211 are also provided in the detection area, and each detection hole 1211 can be used to place a single card test strip 6000, and six second positioning portions are provided on the detection base base 1210, and each second positioning portion corresponds to its own detection hole 1211; when the single card test strip 6000 is placed, each single card test strip 6000 is positioned separately by the second positioning portion to prevent the single card test strip 6000 from displacement;

[0155] The detection support base 1200 has a first positioning portion and a second positioning portion, which can respectively position the combined card test strip 5000 and the single card test strip 6000, so that the detection support base 1200 is suitable for both the combined card test strip 5000 and the single card test strip 6000, greatly improving the versatility.

[0156] For the first positioning portion and the second positioning portion, this embodiment specifically adopts the following structure: the first positioning portion is two positioning protrusions 1240 provided on the detection support seat 1200 and located on both sides of the detection area, and a card groove 5300 is provided on the lower surface of the linked card test strip 5000. When the linked card test strip 5000 is placed on the detection support seat 1200, the positioning protrusions 1240 are stuck in the card grooves 5300 at both ends of the linked card test strip 5000. In order to facilitate the placement of the linked card test strip 5000, four positioning corners 1212 and positioning edges 1213 are provided around the detection area for preliminary limiting.

[0157] The second positioning portion is a positioning groove 1215 (a plurality of barriers 1214 are provided on the detection seat base 1210 at intervals and in parallel, and the positioning groove 1215 is formed between two adjacent barriers 1214) and a positioning protrusion 1216. The six positioning grooves 1215 are arranged in parallel, and each of the detection holes 1211 is respectively located in the positioning groove 1215. The positioning protrusion 1216 is located at one end of the longitudinal direction of the positioning groove 1215. A guide protrusion 1250 is provided between two adjacent positioning protrusions 1216; the main body of each single card test strip 6000 is placed in the positioning groove 1215 to limit the single card test strip 6000 in the horizontal direction, and the positioning protrusion 1216 can position the single card test strip 6000 in the longitudinal direction.

[0158] When placing the single card test strip 6000, the guide protrusion 1250 can play a guiding role to facilitate the placement of the single card test strip 6000. Similarly, a first guide slope 1217 is provided on the side of the barrier 1214, and a second guide slope 1218 is provided at the end of the positioning protrusion 1216.

[0159] A first clearance notch 1220 is provided on the detection support 1200. This first clearance notch 1220 is located near the edge of the detection area and at both ends of the line connecting the six detection holes 1211. A recessed area 1230 is provided between the positioning protrusion 1216 and the positioning groove 1215. At least a portion of this recessed area 1230 is lower than the positioning protrusion 1216 and the positioning groove 1215. The first clearance notch 1220 facilitates the operator's hand to reach through and grasp the combined card test strip 5000. When using a single card test strip 6000, the recessed area 1230 can also provide space for the operator's hand to achieve the same purpose.

[0160] The calibration piece fixing seat 1100 includes a calibration base 1110, namely: a first connecting frame 1120, a second connecting frame 1121 and a blocking bar 1126 arranged relatively to each other, the blocking bar 1126 is connected to the first connecting frame 1120 and the second connecting frame 1121; six first connecting bars 1122 (i.e., surface limiting parts) and six second connecting bars 1123 (second surface limiting parts) are arranged in parallel on the first connecting frame 1120 and the second connecting frame 1121, the first connecting bar 1122 is located at the calibration base The second connecting strip 1123 is located on the lower surface of the calibration base 1110 and on the upper surface of the calibration base 1110. A slot for accommodating the calibration component 4000 is formed between the first connecting strip 1122 and the second connecting strip 1123. The slot is arranged along the main body of the calibration base 1110. The six first connecting strips 1122 are spaced apart from each other, and six calibration holes 1130 are formed between the six spaced apart first connecting strips 1122. A side notch 1140 communicating with the slot is provided on the side of the calibration component fixing base 1100. The detection assembly 1000 is provided with a side opening 1010, which is opposite to the side notch 1140.

[0161] The calibration component fixing seat 1100 is provided with multiple first connecting bars 1122 and second connecting bars 1123. The multiple first connecting bars 1122 are located below the slot, and the multiple second connecting bars 1123 are located above the slot. The calibration component 4000 is inserted from the slot, and its lower part is supported by the multiple first connecting bars 1122, and its upper part is limited by the multiple second connecting bars 1123. The side notch 1140 can facilitate the operator to remove or insert the calibration component 4000. The use of multiple first connecting bars 1122 and second connecting bars 1123 can play a supporting and limiting role and can reduce material loss. The intervals between the multiple first connecting bars 1122 just form six calibration holes 1130.

[0162] On the side near the side notch 1140, the first connecting bar 1122 is closer to the end than the second connecting bar 1123. When inserting the calibration component 4000, the first connecting bar 1122 at this end position can provide guidance and support for the calibration component 4000, facilitating insertion. Furthermore, the first connecting bar 1122 is provided with a third guiding slope 1124 on both the side near the side notch 1140 and the side facing away from the side notch 1140. A fourth guiding slope 1125 is provided on both the side near the side notch 1140 and the side facing away from the side notch 1140 of the second connecting bar 1123, thereby enhancing guidance for the calibration component 4000 during insertion and facilitating insertion. A stop bar 1126 is located on the opposite side of the side notch 1140. Once the calibration component 4000 is inserted into place, the inner end of the calibration component 4000 is blocked by the stop bar 1126, preventing it from moving further.

[0163] The support base 1500 includes a base body 1510, a first light source mounting plate 1620, and a second light source mounting plate 1630. The first light source mounting plate 1620 and the second light source mounting plate 1630 are both in the shape of long strips. A third light source mounting plate 1640 is further provided at the same end direction of the first light source mounting plate 1620 and the second light source mounting plate 1630. The angle between the third light source mounting plate 1640 and the base body 1510 is the same as that of the first light source mounting plate 1620 and the second light source mounting plate 1630. The mounting plate 1630 has equal angles relative to the base substrate 1510, and the first, second, and third light source mounting plates 1620, 1630, and 1640 are mounted on the same surface of the base substrate 1510. The first, second, and third light source mounting plates 1620, 1630, and 1640 have equal angles relative to the base substrate 1510, but the first and second light source mounting plates 1620, 1630, and 1640 are tilted in opposite directions relative to the base substrate 1510. The detection support 1200 is located above the support base 1500, and the detection light source 1660 and sensing element 1651 are mounted on the support base 1500 and offset toward the bottom of the support base 1500. This mounting method increases the distance between the detection aperture and the detection light source 1660 and sensing element 1651, thereby shortening the dimensions of the detection support 1200 and the support base 1500 to meet the requirements for fixed installation of both. In order to meet the requirements of fixed installation size for both, a small focal length detection light source 1660 can be selected.

[0164] Six first light-emitting elements 1621 are mounted longitudinally on the first light source mounting plate 1620, six second light-emitting elements 1631 are mounted longitudinally on the second light source mounting plate 1630, and one third light-emitting element 1641 is mounted on the third light source mounting plate 1640. The number of detection holes 1211 is six. The first light-emitting elements 1621, second light-emitting elements 1631, and third light-emitting elements 1641 have different wavelengths. The detection light source 1660 includes six first light-emitting elements 1621, six second light-emitting elements 1631, and one third light-emitting element 1641.

[0165] A long strip of detection mounting plate 1650 is also provided between the first light source mounting plate 1620 and the second light source mounting plate 1630. The detection mounting plate 1650 is parallel to the base substrate 1510. There are six sensing elements 1651. The sensing elements 1651 are installed on the detection mounting plate 1650 along the longitudinal direction, and each of the sensing elements 1651 corresponds to each of the detection light sources 1660 and the detection holes 1211 respectively.

[0166] The first light source mounting plate 1620 and the second light source mounting plate 1630 have equal angles relative to the base substrate 1510. The third light source mounting plate 1640 is installed at the same end of the first light source mounting plate 1620 and the second light source mounting plate 1630, and is also tilted at the equal angle of the first light source mounting plate 1620 and the second light source mounting plate 1630, so as to achieve the effect that the first light source mounting plate 1620, the second light source mounting plate 1630, and the third light source mounting plate 1640 have equal tilt angles relative to the base substrate 1510. Multiple detection light sources can be arranged at one detection hole 1211, and the structure is more compact. Moreover, since the inclination angles of each light source mounting plate are equal, the detection results will not be affected.

[0167] Since the detection sample has different sensitivities to light of different wavelengths, after multiple light sources of different wavelengths are set, the detection light source of the corresponding wavelength can be selected according to the needs of the detection sample.

[0168] A first guide portion is provided on the support base 1500, and a second guide portion is provided on the calibration component fixing seat 1100. Both the first guide portion and the second guide portion are along the driving direction of the first driving device 2100, and the first guide portion cooperates with the second guide portion. Specifically, a guide edge 1511 is provided on each side of the support base 1500, and a guide side edge 1111 is provided on each side of the calibration component fixing seat 1100.
