Technical Field
[0001] The invention relates to the field of medical detection, and in particular to a chemiluminescent immunoassay analyzer and a reading device thereof. Background Art
[0002] Chemiluminescent immunoassay is an instrument that uses chemiluminescent immunoassay technology and reaction principles to qualitatively or quantitatively detect analytes in human serum, plasma or other body fluid samples, and is used to assist in the diagnosis of related diseases. Chemiluminescent immunoassay consists of two parts, namely the immune response system and the chemiluminescent analysis system. The immune response system marks the marker substance on the antigen or antibody, and after a specific immune reaction, an antigen-antibody complex is formed, and then the marker is detected to determine the analyte. The chemiluminescent analysis system uses the catalysis of the chemiluminescent substance or the oxidation of the oxidant to form an excited intermediate. When this excited intermediate returns to the stable ground state, it will emit photons at the same time, which are detected by the optical signal detector and converted into the concentration of the analyte by the computer data processing system.

[0039] By setting a double-layer shell structure of the first shell 210 and the second shell 220, the action platform 300 can cooperate with the reading component 200 to form a double-layer dark box structure, which has a good light shielding effect. In addition, the photometric hole 222 and the photometric connecting hole 211 are set. When performing luminescence analysis and detection, the action platform 300 moves relative to the reading component 200 and shields the upper end of the second shell 220, and the second shell 220 moves downward relative to the first shell 210, so that the photometric hole 222 is connected with the photometric connecting hole 211, which facilitates the photon counter 230 to measure the photometric hole 222 through the photometric connecting hole 211. 2 to detect the luminescence of the detection cup 1; after completing the luminescence analysis detection, the second shell 220 moves upward and resets, so that the photometric hole 222 and the photometric connecting hole 211 can be completely staggered, and the second shell 220 blocks the photometric connecting hole 211, which can prevent the detection end of the photon counter 230 from being exposed, thereby avoiding affecting the detection reading effect of the photon counter 230 and improving the detection accuracy of the present invention; at the same time, the sleeve structure of the first shell 210 and the second shell 220 can reduce the volume of the reading component 200, so that the volume of the present invention is small and the placement space is saved.
[0040] In this embodiment, if Figure 2 and Figure 3 As shown, the present invention is in a non-detection reading state, the second housing 220 is movably inserted on the first housing 210, the photometric hole 222 and the photometric connecting hole 211 are in a completely staggered state, and the outer wall of the second housing 220 blocks the photometric connecting hole 211, so that the detection head of the photon counter 230 is in a dark environment. During detection, a chemiluminescent liquid is added to the detection cup 1 that has been processed in the early stage, and a control component 500 is provided on the frame 100. The control component 500 controls the driving mechanism 400 to drive the reading component 200 and / or the action platform 300 to move, so that the action platform 300 is covered and shielded at the upper end of the second housing 220. , the action platform 300 and the second shell 220 form an inner dark box structure, the second shell 220 moves downward relative to the first shell 210, and the photometric hole 222 gradually communicates with the photometric connecting hole 211. At this time, since the action platform 300 covers and shields the upper end of the second shell 220, after the photometric hole 222 is connected with the photometric connecting hole 211, the detection head of the photon counter 230 is still in a dark environment; the second shell 220 moves downward relative to the first shell 210 until the photometric hole 222 is completely connected with the photometric connecting hole 211. At this time, the action platform 300 covers the upper end of the first shell 210 to form an outer dark box structure, such as Figure 6 , Figure 8 and Fig. 9 As shown, the present invention is in a detection reading state, the photometric hole 222 and the photometric connecting hole 211 are in a completely connected state, the object to be detected in the detection cup 1 reacts immune and starts to emit light, and the photon counter 230 measures the number of photons and analyzes and processes and feeds back the results.
[0041] In actual application, the movement of the second shell 220 can also be achieved by setting a driving device or other structures. The photon counter 230 is a commonly used light-emitting detection element in this field. It and the control component 500 can be selected and set according to actual use needs, which can be understood by those skilled in the art. At the same time, the specific structure of the action platform 300 is not limited here, as long as it can cover the upper end of the second shell 220. The specific structure of the driving mechanism 400, the driving connection method, the specific structure of the reading component 200, etc. are not described in detail here, and will be described in detail below.
[0042] In some embodiments, the reading assembly 200 further includes an elastic member 240, and two ends of the elastic member 240 are respectively connected to the lower end of the first housing 210 and the lower end of the second housing 220. By providing the elastic member 240, the upward movement and reset of the second housing 220 can be facilitated, and at the same time, the photometric hole 222 and the photometric connecting hole 211 can be completely staggered, so that the second housing 220 can cover the photometric connecting hole 211, and the structure is simple, which can reduce the volume of the reading assembly 200.
[0043] In this embodiment, if Figure 3 and Figure 4 As shown, the elastic member 240 is a spring, and the lower end of the second shell 220 is provided with a spring connecting hole 224 formed by an upward depression, and the lower end of the first shell 210 is provided with a connecting boss 213 formed by an upward protrusion. One end of the elastic member 240 is sleeved on the connecting boss 213 and abuts against the bottom of the connecting boss 213, and the other end thereof extends into the spring connecting hole 224 and abuts against the bottom of the spring connecting hole 224. When the second shell 220 moves downward, the elastic member 240 is compressed, and at the same time, the connecting boss 213 extends into the spring connecting hole 224; when the action platform 300 moves upward relative to the reading component 200, the second shell 220 is reset under the action of the elastic member 240, so that the photometric hole 222 is completely staggered with the photometric connecting hole 211, and its structure is simple and the connection is stable. In actual application, in addition to the elastic member 240, a driver can also be provided to reset the second shell 220. In addition to the spring, a spring or other elastic material can also be provided. The connection method of the elastic member 240 can also be changed according to actual use needs and is not limited here.
[0044] In some embodiments, the action platform 300 is provided with a first sealing portion 310 and a second sealing portion 320, respectively, the upper end of the first shell 210 is provided with an outer shell sealing groove 212 for inserting the first sealing portion 310, and the upper end of the second shell 220 is provided with an inner shell sealing step 223 for abutting the second sealing portion 320. By providing the outer shell sealing groove 212 and the inner shell sealing step 223, when the first sealing portion 310 is connected to the upper end of the first shell 210 and the second sealing portion 320 is connected to the upper end of the second shell 220, a multi-layer structure is formed at the connection, which can enhance the light-shielding sealing effect, so that the reading component 200 obtains a better detection reading effect.

Correspondingly, the first sealing portion 310 and the second sealing portion 320 are both annular protrusion structures. When the action platform 300 moves downward relative to the reading component 200, the second sealing portion 320 first abuts against the inner shell sealing step portion 223 to form a sealed connection and pushes the second shell 220 to move downward. Subsequently, the first sealing portion 310 is inserted into the outer shell sealing groove 212 to form a sealed connection, so that the connection between the action platform 300 and the reading component 200 forms a multi-layer structure to enhance the light-shielding sealing effect. Of course, in actual application, the specific structure of the outer shell sealing groove 212 and the inner shell sealing step portion 223 is not limited to this, and can also be changed according to actual use needs. At the same time, the specific shapes of the first sealing portion 310 and the second sealing portion 320 can also be changed accordingly. Moreover, the connection between the first sealing portion 310 and the outer shell sealing groove 212 and the connection between the second sealing portion 320 and the inner shell sealing step portion 223 can be provided with a sealing rubber ring to improve the sealing effect, which is not limited here.

[0047] In this embodiment, if Figure 6 and Figure 7As shown, the action platform 300 is provided with a drop connection seat 330, a drop assembly 340 and a drop connection hole 350. The existing chemiluminescent immunoassay can be roughly divided into two types, namely, delayed luminescence detection in which a chemiluminescent liquid is dripped into the test cup 1 and then placed in a dark room for reading, and instant luminescence detection in which a chemiluminescent liquid is dripped into the test cup 1 after the test cup 1 is placed in a dark room for instant reading. The action platform 300 provided with the drop connection seat 330, the drop assembly 340 and the drop connection hole 350 can be applicable to the above two chemiluminescent immunoassays. When used for delayed luminescence detection, the drop assembly 340 is disassembled and its installation position is sealed, and then the delayed luminescence detection can be performed as described above; when used for instant luminescence detection, the drop assembly 340 is connected to an external chemiluminescent liquid device, and after the action platform 300 is connected to the reading assembly 200, the upper end of the test cup 1 extends into the drop connection hole 350, and the drop assembly 340 can perform the instant luminescence detection as described above on the chemiluminescent liquid dripped into the test cup 1. In actual application, the specific structure of the drip connection seat 330 and the drip assembly 340 can be set according to actual use needs, and there are also various ways to disassemble them, such as through threaded connection, snap connection, etc. The number of settings of the drip assembly 340 can also be set according to actual use needs, and there is no restriction here.
[0048] In some embodiments, a liquid extraction joint assembly 360 is provided on the action platform 300, and the liquid extraction joint assembly 360 includes a liquid extraction tube 361 that can be inserted into the detection cup 1, and the liquid extraction joint assembly 360 can be connected to an external suction device. By providing the liquid extraction tube 361, the waste liquid in the detection cup 1 after the detection is completed is sucked out by connecting the liquid extraction tube 361 to the external suction device, which can avoid pollution caused by leakage of waste liquid, and at the same time can reduce manual labor and improve the degree of automation.
[0049] In this embodiment, if Figure 6 As shown, a liquid extraction joint assembly 360 is provided on the action platform 300, and the action platform 300 moves downward relative to the reading assembly 200, so that the liquid extraction tube 361 extends into the detection cup 1, and the waste liquid in the detection cup 1 is sucked out by an external suction device. In actual application, the specific structure of the liquid extraction joint assembly 360 can be set accordingly according to actual use needs, and is not limited here.
[0050] In some embodiments, the liquid extraction joint assembly 360 further includes a cup removal member 362 sleeved on the liquid extraction tube 361, and the cup removal member 362 can lift the detection cup 1 on the second housing 220 from the cup placement hole 221. By providing the cup removal member 362 to lift and detach the detection cup 1 on the second housing 220 from the cup placement hole 221, it is possible to facilitate the next detection and cup placement, reduce manual labor, and improve the degree of automation.
[0051] In this embodiment, if Figure 2 and Figure 6 As shown, a cup-removing member 362 is sleeved on the liquid-drawing tube 361. The cup-removing member 362 can be made of elastic material and has an inverted cone structure. When the liquid-drawing tube 361 moves downward and extends into the detection cup 1, the inverted cone-shaped cup-removing member 362 simultaneously extends into the detection cup 1. Due to its inverted cone structure, the cup-removing member 362 can be engaged with the upper end of the detection cup 1 when moving downward. When the action platform 300 moves upward relative to the reading component 200, the cup-removing member 362 lifts the engaged detection cup 1 from the cup placing hole 221, thereby realizing the removal of the detection cup 1 from the reading component 200.
[0052] In this embodiment, Figure 2 and Figure 5 As shown, the reading component 200 is further provided with a cup removing piece 250, and the cup removing piece 250 is provided with a clamping notch 251. The cup removing piece 362 can be moved relative to the cup removing piece 250 to clamp the clamping notch 251 of the cup removing piece 250 on the cup removing piece 362 with the detection cup 1 or on the detection cup 1. Then, the cup removing piece 362 is moved upward relative to the cup removing piece 250 to clamp the detection cup 1 on the cup removing piece 362 through the clamping notch 251 and detach it from the cup removing piece 362, so as to realize the cup removing operation of the cup removing piece 362. Of course, in actual application, in addition to the cup removing piece 362 and the cup removing piece 250 structure of the above structure, the cup removing piece 362 can also be set as a robot to grab and detach the detection cup 1 on the reading component 200.

[0054] In some embodiments, the rack 100 is provided with a cup-removing detection assembly 110, which can detect the presence of the detection cup 1 on the cup-removing member 362. By providing the cup-removing detection assembly 110 to detect whether the detection cup 1 is extracted from the cup-removing member 362, it is possible to avoid the cup-removing member 362 from performing the next cup-removing operation when there is still the detection cup 1 on it, thereby avoiding the occurrence of cup-removing failures, and at the same time improving the degree of intelligence of the present invention.
[0055] In this embodiment, if Figure 2 and Figure 6As shown, a cup-removing detection assembly 110 is provided on the frame 100.
