Description

Technical Field

[0001] The invention relates to the technical field of homogeneous chemiluminescence detectors, and in particular to a homogeneous chemiluminescence detector. Background Art

[0002] Homogeneous chemiluminescence detector is a commonly used detection instrument. During the detection, two substances, substrate and reconstitution solution, generally need to be added to the reaction cup. In order to ensure the detection accuracy, the detection darkroom needs to be heated and kept at 37°C. At the same time, before adding the substrate and reconstitution solution, the substrate and reconstitution solution need to be heated by incubation. After heating, the substrate and reconstitution solution are supplied to the detection darkroom through the substrate pump and reconstitution solution pump. After replacing the substrate container and the reconstitution solution container, there will be some air bubbles in the substrate tube and the reconstitution solution tube. In order to discharge the air bubbles, the substrate tube and the reconstitution solution tube need to be cleaned to discharge the air bubbles. The existing homogeneous chemiluminescence detector generally makes the incubation and cleaning into one device, and then makes the detection into one device. In this way, the instrument is not only complex in structure, relatively bulky, and troublesome to install, but also relatively cumbersome to use and prone to problems.

Among them, two bearings are preferably provided between the rotating shaft 104 and the darkroom lower shell 106, and the two bearings are respectively bearing 105-1 and bearing 105-2. The darkroom lower shell 106 is preferably connected to the darkroom upper shell 102 and the heating module by bolts. A photomultiplier tube 201 is provided on one side of the darkroom lower shell 106, and a through hole 127 is provided at the connection position between the darkroom lower shell 106 and the photomultiplier tube 201.

A darkroom flip cover 101 is provided on the upper side of the darkroom upper shell 102, and a rotor 103 is provided on the upper end of the rotating shaft 104. The rotor 103 is disposed in a cavity inside the darkroom lower shell 106 as a whole, and the rotor 103 can rotate together with the rotating shaft 104. The lower end of the rotating shaft 104 extends out of the lower side of the bracket 6, and the lower end of the rotating shaft 104 can be limited by providing a limit block 110 to prevent the rotating shaft 104 from moving upward and escaping from the upper side of the darkroom lower shell 106. The rotating shaft 104 is in transmission connection with a motor 115, and the rotating shaft 104 is driven by the motor 115 to rotate. In order to facilitate the positioning of the rotor 103, an optical coupling baffle 111 is further provided at the lower end of the rotating shaft 104. The optical coupling baffle 111 is provided with a groove. Photoelectric beam switches 130 are arranged on the upper and lower sides of the optical coupling baffle 111.

The detection port 123 is used to expose the middle of the cuvette placement slot 118, and the position of the detection port 123 corresponds to the position of the through hole 127. When the motor 115 rotates, the rotor 103 is driven to rotate, so that the position of the cuvette placement slot 118 located below the substrate tube, the reconstitution solution tube and the darkroom flip cover 101 can be adjusted. When the darkroom flip cover 101 is opened, the cuvette to be detected can be placed in the cuvette placement slot 118 or the detected cuvette can be taken out from the cuvette placement slot 118. A heating groove 7 for accommodating a substrate tube and a reconstitution solution tube is provided in the heating module. The substrate tube and the reconstitution solution tube enter the heating module from the outside respectively and are arranged along the heating groove 7. The upper side of the heating module can heat the air in the darkroom upper shell 102 to keep the temperature in the darkroom upper shell 102 at a set temperature. The lower side of the heating module can heat the substrate and the reconstitution solution in the substrate tube and the reconstitution solution tube in the heating groove 7 respectively.

When it is necessary to add the substrate or reconstitution solution into the reaction cup, the substrate pump 301 and the reconstitution solution pump 302 extract the substrate and the reconstitution solution from the substrate container and the reconstitution solution container respectively. When the substrate and the reconstitution solution pass through the heating groove 7 in the heating module, they are heated to the set temperature (37° C.). The heating module, the photomultiplier tube 201, the counter 202, the motor 115, the substrate pump 301, and the reconstitution solution pump 302 are all connected to the control board 4, and the control board 4 controls their work and obtains the detection results respectively.

[0025] The heating module of the embodiment of the present invention includes a heating plate 107 arranged on the lower side of the darkroom lower shell 106, a sensor mounting hole 124 is provided on the darkroom lower shell 106, a temperature sensor is arranged in the sensor mounting hole 124, and a preheating disk 108 is arranged at intervals on the lower side of the temperature sensor heating plate 7, and the gap between the preheating disk 108 and the heating plate 107 is preferably 0.5 to 1 mm. In this way, the preheating disk 108 and the detection darkroom are ensured to be at the same constant temperature, and it is avoided that the preheating disk 108 is close to the heating plate 107 and causes overheating. The bottom of the darkroom lower shell 106 and the preheating disk 108 are preferably made of aluminum, which has a good thermal conductivity. The lower side of the preheating disk 108 is connected to a heat insulation board 109, and the heat insulation board 109 is preferably made of an engineering plastic board.

The control board 4 controls the heater 107 to work according to the signal fed back by the temperature sensor, and controls the temperature within the set range. It is also preferred that a temperature switch mounting hole 125 is also provided on one side of the sensor mounting hole 124, and a temperature switch is provided in the temperature switch mounting hole 125. The temperature switch is connected to the control board 4. When the temperature sensor fails, if the temperature reaches the temperature switch action temperature, the temperature switch can provide a switch protection signal to the control board 4 to avoid excessive temperature. The heating groove 7 is preferably arranged in a winding manner to improve the heating effect.

[0026] The cross-section of the darkroom lower shell 106 of the embodiment of the present invention is square-shaped, and a notch is vertically provided at one corner of the darkroom lower shell 106. Two transition grooves 8 for accommodating the substrate tube and the recovery solution tube are provided in the notch, and the lower end of the transition groove 8 is arranged opposite to the outlet of the heating groove 7, so that the substrate tube and the recovery solution tube directly enter the transition groove 8 after coming out of the heating groove 7, and the upper end of the transition groove 8 is arranged flush with the upper surface of the darkroom lower shell 106, so that the substrate tube and the recovery solution tube directly enter the upper side of the darkroom lower shell 106 through the notch, and a pressing block 114 is connected to the outer side of the notch, and the pressing block 114 is preferably bolted to the darkroom lower shell 106. Under the action of the pressing block 114, on the one hand, the substrate tube and the recovery solution tube can be prevented from escaping from the transition groove 8, and on the other hand, it can have a certain heat preservation effect to prevent the substrate and the recovery solution in the substrate tube and the recovery solution tube from lowering their temperature before entering the upper side of the darkroom lower shell 106.

[0027] A liquid injection pillar 112 is fixed on the upper side of the darkroom lower shell 106. The liquid injection pillar 112 is L-shaped, and two grooves 126 are arranged on the outside. Each groove 126 is arranged in an n-shaped shape. Both ends of the two grooves 126 are arranged downward, and one end of each groove 126 is arranged opposite to the upper end of one of the transition grooves 8. Then, the substrate tube and the reconstitution solution tube can enter the groove 126 from the transition groove 8 respectively. The other end of the groove 126 is arranged downward on the upper side of the reaction cup placement groove 118, and a tube pressing block 113 is fixed on the outside of the liquid injection pillar 112. The tube pressing block 113 is preferably fixed to the liquid injection pillar 112 by bolts, and the tube pressing block 113 can stably limit the substrate tube and the reconstitution solution tube in the groove 126. A receiving cavity is provided on the darkroom upper shell 102 at a position corresponding to the liquid injection pillar 112, and the size and shape of the receiving cavity are adapted to the liquid injection pillar 112.

[0028] The cuvette placement slot 118 of the embodiment of the present invention is preferably arranged through the rotor 103, and a liquid collecting slot 116 is arranged on the upper side of the bottom of the darkroom lower shell 106, and the liquid collecting slot 116 is preferably arranged directly below the cuvette placement slot 118. A discharge port 117 connected to the liquid collecting slot 116 is arranged on the darkroom lower shell 106, and the discharge port 117 is connected to the discharge pump 303 through a discharge pipe. When air appears in the substrate tube and the reconstitution solution tube, the substrate pump 301 and the reconstitution solution pump 302 can be controlled to operate, and the substrate and reconstitution solution containing the air part are directly discharged into the darkroom lower shell 106, and then the waste liquid in the liquid collecting slot 116 is discharged through the discharge pump 303.

[0029] Since the cavity in the lower shell 106 of the darkroom is cylindrical, the liquid collecting tank 116 of the embodiment of the present invention is preferably arranged in a ring shape. In order to facilitate the discharge of waste liquid in the liquid collecting tank 116, the depth of the liquid collecting tank 116 is a smooth gradient structure, and the depth of the liquid collecting tank 116 is arranged to gradually decrease from deep to shallow from one side of the discharge port 117 to the opposite side of the discharge port 117.

[0030] In order to facilitate the detection of whether there is a reaction cup in the reaction cup placement groove 118 under the darkroom flip cover 101, a mounting plate 121 is bolted to the middle of the darkroom lower shell 106 on one side of the darkroom flip cover 101, and an infrared transmitting and receiving module 122 is provided on the mounting plate 121. The infrared transmitting and receiving module 122 is connected to the control board 4 and is arranged opposite to the detection port 123. The control board 4 supplies power to the infrared transmitting and receiving module 122. If a reaction cup is placed in the reaction cup placement groove 118 under the darkroom flip cover 101, the infrared light emitted by the infrared transmitting and receiving module 122 will be irradiated on the reaction cup through the detection port 123 and will return, and then be received by the infrared transmitting and receiving module 122, thereby sensing that a reaction cup is currently placed.

[0031] One end of the darkroom flip cover 101 of the embodiment of the present invention is hinged to the darkroom upper shell 102, and the other end of the darkroom flip cover 101 is provided with a sensing block 119, which is preferably a magnetic block. The sensing block 119 is preferably pressed on the darkroom flip cover 101 through a pull block 131, and the pull block 131 is bolted to the darkroom flip cover 101. A proximity switch 120 that cooperates with the sensing block 119 is provided on the darkroom lower shell 106, and the proximity switch 120 is connected to the control board 4. When the darkroom flip cover 101 is in an open state, the sensing block 119 will not trigger the proximity switch 120 to operate. When the darkroom flip cover 101 is in a closed state, the proximity switch 120 can be triggered to operate, and the proximity switch 120 can feed back the state of the darkroom flip cover 101 to the control board 4, thereby avoiding invalid detection of the darkroom flip cover 101 in an open state.
