Abstract
Description
Technical Field
[0001] This application relates to the field of reagent chamber testing technology, and in particular to a reagent sample chamber testing fixture. Background Technology
[0002] The reagent and sample compartment is a core functional module in medical devices used to store reagents and samples. Its structure is as follows: Figure 1 and Figure 2 As shown, reagent sample compartments 01 typically have multiple independent sample compartments 02 evenly distributed in the circumferential direction to ensure the partitioned management of reagents and samples. To maintain the activity of the reagents in each sample compartment 02, the temperature inside the compartment must be strictly controlled at a low temperature. For this purpose, the bottom of the reagent sample compartment 01 usually integrates a cooling chip 03 and a heat dissipation module 04. The heat dissipation module 04 includes a metal heat dissipation plate 041 that is tightly attached to the cooling chip 03. The heat dissipation plate 041 has a coolant circulation channel inside, and the outer surface of the heat dissipation plate 041 is provided with an outlet connector 043 and an inlet connector 042 that are connected to the coolant circulation channel.
[0003] The functionality of the reagent sample compartment components is crucial to the quality of reagent preservation and the accuracy of subsequent test results. Therefore, before the reagent sample compartment is put into use, its functions must be rigorously tested to ensure that its performance meets the requirements.
[0004] However, since the functional testing of the reagent sample compartment requires simultaneous verification of the circuit and liquid circuit, the reagent sample compartment is usually loaded onto the host device and tested together with the host during testing. If the reagent sample compartment is found to be malfunctioning during testing, it needs to be disassembled from the host and re-tested, resulting in a long rework cycle, a significant increase in manpower and time costs, and a serious impact on production efficiency, which is obviously insufficient. Utility Model Content
[0005] In order to achieve pre-testing of reagent sample chambers and reduce the production efficiency reduction caused by whole-machine testing methods, this application provides a reagent sample chamber testing fixture.
[0006] The reagent sample chamber testing fixture provided in this application adopts the following technical solution:
[0007] A reagent sample chamber testing fixture includes a support frame, on which a switching power supply, a heat sink assembly, and a data acquisition instrument are mounted. The switching power supply provides electrical energy to the heat sink assembly and the reagent sample chamber. The heat sink assembly exchanges heat with the heat dissipation module of the reagent sample chamber. The data acquisition instrument is electrically connected to temperature probes corresponding to multiple sample chambers. The temperature probes monitor the temperature inside each sample chamber in real time to determine whether the reagent sample chamber assembly is functioning properly.
[0008] By adopting the above technical solution, after all the components of the reagent sample chamber are assembled, the reagent sample chamber is connected to the switching power supply and the heat sink assembly respectively. Then, the temperature probes are placed inside the sample chamber one by one, and the reagent sample chamber is started through a remote host computer.
[0009] During the test, the switching power supply provides power to the heat sink assembly and reagent sample chamber, ensuring the normal operation of the circuit and liquid circuit during the test. The heat sink assembly and the heat dissipation module of the reagent sample chamber directly exchange heat, which can quickly simulate the heat dissipation conditions of the reagent sample chamber in actual use. The data acquisition instrument monitors the temperature change inside each sample chamber in real time through the temperature probe, accurately judges whether the components of the reagent sample chamber are functioning normally, and thus quickly locates potential problems.
[0010] In summary, this testing fixture enables independent testing of the reagent sample chamber through a switching power supply, heat sink assembly, and data acquisition instrument. This eliminates the need for the host equipment during the testing process, allowing for the early detection and resolution of functional defects. It prevents problems from being exposed during the host equipment integration stage, reduces rework workload, and improves the production efficiency of the reagent sample chamber.
[0011] Optionally, the radiator assembly includes a heat dissipation radiator mounted on the support frame. The inlet of the heat dissipation radiator is connected to the outlet connector via a heat dissipation pipe. The outlet of the heat dissipation radiator is connected to a coolant tank via a heat dissipation pipe. The coolant tank is filled with coolant. The outlet of the coolant tank is connected to the inlet connector via a heat dissipation pipe. A circulation pump that provides the flow power of the coolant is mounted on the heat dissipation pipe.
[0012] By adopting the above technical solution, after the reagent sample chamber is started, the cooling chip and heat sink assembly of the reagent sample chamber begin to work. The circulation pump delivers the coolant in the coolant tank to the heat sink. The coolant in the heat sink absorbs the heat generated by the cooling chip, and under the power of the circulation pump, the coolant flows along the heat sink pipe to the heat sink. The heat generated by the cooling chip is dissipated through heat exchange between the heat sink and the outside. The heat sink assembly constructs a complete coolant circulation system, which can quickly transfer the heat generated by the reagent sample chamber to the heat sink to achieve efficient heat dissipation. This ensures that the sample chamber can maintain a stable low temperature environment during the test, thereby verifying whether its heat dissipation performance meets the requirements.
[0013] Optionally, the support frame is provided with a liquid replenishment assembly, which includes a liquid replenishment tank disposed on the support frame. The liquid replenishment tank is filled with coolant and is connected to the coolant tank via a liquid replenishment pipe. A mounting plate is disposed inside the liquid replenishment pipe, and an outlet is provided on the mounting plate. Sliding grooves are provided on the inner sidewalls of the liquid replenishment pipe on opposite sides. A baffle plate is slidably connected in the sliding groove, and a spring is disposed in the sliding groove. One end of the spring is disposed on the baffle plate, and the other end is disposed on the inner sidewall of the sliding groove. In the natural state, the baffle plate overlaps the mounting plate and blocks the outlet. A driving component is provided in the coolant tank to drive the baffle plate to detach from the mounting plate.
[0014] By adopting the above technical solution, when the level in the coolant tank drops to a point where it can no longer maintain the normal cooling of the radiator components, the driving component drives the baffle plate to detach from the mounting plate. At this time, the outlet opens and the outlet pipe is in a flowing state. The coolant inside the replenishment tank enters the coolant tank through the outlet pipe. When the level returns to the preset value, the baffle plate is pulled by the spring and resets to the state of blocking the outlet. At this time, the outlet pipe is in a disconnected state.
[0015] The coolant replenishment component enables automatic replenishment of the coolant tank, preventing overheating of the reagent sample chamber due to insufficient coolant. It also eliminates the need for frequent manual addition of coolant by workers, extending the service life of the testing fixture.
[0016] Optionally, the driving component is a float disposed in the coolant tank, a vertical rod is disposed in the coolant tank, the float is slidably connected to the vertical rod, a pull rope is disposed on the outer surface of the float, and the end of the pull rope away from the float is disposed on a baffle plate, and the buoyancy force generated by the coolant in the coolant tank on the float is greater than the elastic force of the spring.
[0017] When the water level in the cooling tank drops, and when the water level falls below the preset value, the float descends vertically on the vertical rod. At this time, the float overcomes the spring force and pulls the baffle plate. The pull rope is in a taut state and pulls the baffle plate to disengage from the mounting plate, opening the outlet to allow for liquid replenishment. As the water level rises, the float gradually moves upward on the vertical rod, the pull rope gradually relaxes, and the pulling force of the pull rope on the baffle plate gradually becomes less than the spring force. The spring resets and pulls the baffle plate to re-seal the outlet.
[0018] Optionally, a liquid level sensor is installed inside the replenishment tank. The liquid level sensor is used to monitor the liquid level in the replenishment tank in real time. When the coolant capacity in the replenishment tank is lower than a preset alarm level, the liquid level sensor issues a liquid level alarm.
[0019] By adopting the above technical solution, when the coolant in the replenishment tank is lower than the preset value, the system will issue an early warning to remind the operator to replenish it in time, so as to ensure that the coolant in the replenishment tank is sufficient and thus ensure the continuous use of the coolant tank.
[0020] Optionally, a sealing ring is provided on the surface of the baffle plate facing the mounting plate, and a sealing groove is provided on the mounting plate to cooperate with the sealing ring.
[0021] By adopting the above technical solution, the sealing between the baffle plate and the mounting plate is achieved through the sealing fit of the sealing ring and the sealing groove, effectively preventing the possibility of coolant leakage through the gap between the baffle plate and the mounting plate.
[0022] Optionally, a push handle is provided on one side of the support frame, and casters are provided around the bottom of the support frame.
[0023] By adopting the above technical solution, the ease of moving the testing fixture is improved by pushing the handle and the casters, making it easier for workers to move the testing fixture between different testing points.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] This application, by setting up a switching power supply, heat sink assembly and data acquisition instrument, enables the trial fixture to independently test the reagent sample chamber. This allows the testing process of the reagent sample chamber to be carried out without relying on the host equipment, thus discovering and solving functional defects in advance, avoiding problems from being exposed in the host debugging stage, reducing rework workload and improving the production efficiency of the reagent sample chamber.
[0026] This application, by setting up a liquid replenishment component and a driving component, enables the automatic replenishment of coolant in the coolant tank when the level in the coolant tank drops to a point where it can no longer maintain the normal cooling of the radiator assembly. The driving component then drives the baffle plate to detach from the mounting plate, allowing the coolant inside the replenishment tank to enter the coolant tank through the outlet pipe. This achieves automatic replenishment of coolant in the coolant tank, avoiding overheating of the reagent sample chamber due to insufficient coolant. Furthermore, it eliminates the need for frequent manual addition of coolant by workers, extending the service life of the testing fixture. Attached Figure Description

Detailed Implementation
[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0034] This application discloses a reagent sample chamber testing fixture.
[0035] Reference Figure 1 , Figure 2 and Figure 3 A reagent sample chamber testing fixture includes a support frame 1. A switching power supply 2, a heat sink assembly 3, and a data acquisition instrument 4 are mounted on the support frame 1. The switching power supply 2 provides power to the heat sink assembly 3 and the reagent sample chamber 01. The heat sink assembly 3 is used for heat exchange with the heat dissipation module 04 of the reagent sample chamber 01. In this embodiment, the support frame 1 has a three-layer frame structure. The switching power supply 2 and the data acquisition instrument 4 are placed on the top layer of the support frame 1. The data acquisition instrument 4 is electrically connected to a temperature probe 5 corresponding to a plurality of sample chambers 02. The temperature probe 5 is used to monitor the temperature inside each sample chamber 02 in real time and to determine whether the reagent sample chamber 01 assembly is functioning normally.
[0036] Reference Figure 1 , Figure 2 and Figure 3The radiator assembly 3 is fixedly installed in the middle layer of the support frame 1. The radiator assembly 3 includes a heat dissipation fin 31 fixedly installed on the support frame 1. In this embodiment, the heat dissipation fin 31 is made of copper. The inlet of the heat dissipation fin 31 is connected to the liquid outlet connector 043 through the heat dissipation pipe 32. The outlet of the heat dissipation fin 31 is connected to a coolant tank 33 through the heat dissipation pipe 32. The coolant tank 33 is fixedly installed on the support frame 1 and stores coolant inside. The outlet of the coolant tank 33 is connected to the liquid inlet connector 042 through the heat dissipation pipe 32. A circulation pump 34 that provides flow power for the coolant is fixedly installed on the outer surface of the coolant tank 33. The circulation pump 34 is connected to the coolant flow channel through the heat dissipation pipe 32.
[0037] Reference Figure 3 The outer surface of the support frame 1 is fixedly connected with a push handle 6 that is easy for workers to grip. The bottom of the support frame 1 is equipped with casters 7. In this embodiment, the casters 7 have a self-locking function. By pushing the handle 6 and the casters 7, the ease of moving the test fixture is improved, making it easier for workers to move the test fixture between different test points.
[0038] After all the components of the reagent sample chamber 01 are assembled, the worker pushes the support frame 1 to the designated test point. Then, the switching power supply 2 is connected to the electrical components in the reagent sample chamber 01 and the heat sink assembly 3 through wires. Subsequently, the liquid inlet connector 042 and the coolant tank 33 are connected through the heat pipe 32, and the liquid outlet connector 043 is connected to the heat sink 31. Finally, the temperature probes 5 are placed inside the sample chamber 02 one by one, and the reagent sample chamber 01 is started through the remote host computer.
[0039] During the test, the switching power supply 2 provides power to the heat sink assembly 3 and the reagent sample chamber 01 to ensure the normal operation of the circuit and liquid circuit during the test. The circulation pump 34 delivers the coolant in the coolant tank 33 to the heat sink 041. The coolant in the heat sink 041 absorbs the heat generated by the cooling chip 03. Driven by the circulation pump 34, the coolant flows along the heat pipe 32 to the heat sink 31. The heat generated by the cooling chip 03 is dissipated through the heat exchange between the heat sink 31 and the outside world, thereby simulating the heat dissipation conditions of the reagent sample chamber 01 in actual use. The data acquisition instrument 4 monitors the temperature change inside each sample chamber 02 in real time through the temperature probe 5 to accurately determine whether the component functions of the reagent sample chamber 01 are normal, thereby quickly locating potential problems.
[0040] In summary, this testing fixture enables independent testing of the reagent sample chamber 01 through the switching power supply 2, heat sink assembly 3, and data acquisition instrument 4. This allows the testing process of the reagent sample chamber 01 to proceed without relying on the host equipment, enabling early detection and resolution of functional defects, preventing problems from being exposed during the host integration and debugging stage, reducing rework workload, and improving the production efficiency of the reagent sample chamber 01.
[0041] Reference Figure 4 and Figure 5 During the flow of coolant, some coolant will remain on the inner wall of the heat sink 32. At the same time, as the coolant temperature rises, some coolant will evaporate. Therefore, after a long period of operation, the water level inside the coolant tank 33 will drop. When the water level drops to the preset height, the radiator assembly 3 will not be able to maintain the normal cooling of the cooling chip 03, thus hindering the normal operation of the test process.
[0042] To solve the above-mentioned technical problems, a liquid replenishment component 8 is provided on the support frame 1. The liquid replenishment component 8 includes a liquid replenishment tank 81 fixedly installed on the support frame 1. The liquid replenishment tank 81 is filled with coolant. A liquid replenishment pipe 82 communicating with the coolant tank 33 is fixedly installed on the outer surface of the liquid replenishment tank 81. An installation plate 83 is fixedly connected inside the liquid replenishment pipe 82. In this embodiment, the installation plate 83 is annular and has an outlet 831 for coolant to flow through.
[0043] Reference Figure 4 and Figure 5 The inner walls of the replenishment pipe 82 are provided with sliding grooves 821, which are parallel to the length of the replenishment pipe 82. The two sliding grooves 821 are slidably connected to a baffle plate 84. A sealing ring 841 is fixedly connected to the surface of the baffle plate 84 facing the mounting plate 83. A sealing groove 832 that cooperates with the sealing ring 841 is provided on the mounting plate 83. The sealing cooperation between the sealing ring 841 and the sealing groove 832 prevents the leakage of coolant.
[0044] Reference Figure 4 and Figure 5 Each sliding groove 821 is equipped with a spring 85. One end of the spring 85 is fixedly connected to the baffle plate 84, and the other end is fixedly connected to the inner side wall of the sliding groove 821 away from the mounting plate 83. In the natural state, the baffle plate 84 overlaps the mounting plate 83 and blocks the liquid outlet 831. The coolant tank 33 is equipped with a driving component that drives the baffle plate 84 to disengage from the mounting plate 83.
[0045] Reference Figure 4 and Figure 5 The driving component is a float 9 floating inside the coolant tank 33. A vertical rod 10 is fixedly installed inside the coolant tank 33. The float 9 is slidably connected to the vertical rod 10. A limiting groove 101 is provided along the length of the vertical rod 10. A limiting block (not shown in the figure) is fixedly connected to the inner wall of the float 9 and slides with the limiting groove 101. The rotation of the float 9 is limited by the sliding cooperation between the limiting groove 101 and the limiting block. A pull rope 91 is fixedly connected to the outer surface of the float 9. The end of the pull rope 91 away from the float 9 is fixedly connected to the baffle plate 84. The buoyancy of the coolant in the coolant tank 33 on the float 9 is greater than the elastic force of the spring 85.
[0046] When the water level in the coolant tank 33 drops to a level that can no longer maintain the normal cooling of the radiator assembly 3, the float 9 descends vertically on the vertical rod 10. The float 9 overcomes the elastic force of the spring 85 and pulls the baffle plate 84. The pull rope 91 is in a taut state and pulls the baffle plate 84 to separate from the mounting plate 83. At this time, the outlet 831 opens and the outlet pipe is in a flowing state. The coolant inside the replenishment tank 81 enters the coolant tank 33 through the outlet pipe.
[0047] As the water level rises, the float 9 gradually moves upward on the vertical rod 10, the pull rope 91 gradually becomes slack, and the pulling force of the pull rope 91 on the baffle plate 84 gradually becomes less than the elastic force of the spring 85. The spring 85 resets and pulls the baffle plate 84 to re-seal the outlet 831.
[0048] Reference Figure 4 and Figure 5 A liquid level sensor (not shown in the figure) is fixedly installed inside the replenishment tank 81. The liquid level sensor is used to monitor the liquid level height of the replenishment tank 81 in real time. When the coolant capacity in the replenishment tank 81 is lower than the preset alarm level, the system will issue an early warning to remind the operator to replenish it in time to ensure that the coolant in the replenishment tank 81 is sufficient, thereby ensuring the continuous use of the coolant tank 33.
[0049] The implementation principle of a reagent sample chamber testing fixture in this application embodiment is as follows: After the reagent sample chamber 01 is assembled, the worker pushes the support frame 1 to the designated test point. Then, the switching power supply 2 is connected to the electrical components in the reagent sample chamber 01 and the heat sink assembly 3 through wires. Subsequently, the liquid inlet connector 042 and the coolant tank 33 are connected through the heat sink 32, and the liquid outlet connector 043 is connected to the heat sink 31. Finally, the temperature probes 5 are placed inside the sample chamber 02 one by one, and the reagent sample chamber 01 is started through the remote host computer.
[0050] During the test, the switching power supply 2 provides power to the heat sink assembly 3 and the reagent sample chamber 01 to ensure the normal operation of the circuit and liquid circuit during the test. The circulation pump 34 delivers the coolant in the coolant tank 33 to the heat sink 041. The coolant in the heat sink 041 absorbs the heat generated by the cooling chip 03. Driven by the circulation pump 34, the coolant flows along the heat pipe 32 to the heat sink 31. The heat generated by the cooling chip 03 is dissipated through the heat exchange between the heat sink 31 and the outside world, thereby simulating the heat dissipation conditions of the reagent sample chamber 01 in actual use. The data acquisition instrument 4 monitors the temperature change inside each sample chamber 02 in real time through the temperature probe 5 to accurately determine whether the component functions of the reagent sample chamber 01 are normal, thereby quickly locating potential problems.
[0051] In summary, this testing fixture enables independent testing of the reagent sample chamber 01 through the switching power supply 2, heat sink assembly 3, and data acquisition instrument 4. This allows the testing process of the reagent sample chamber 01 to proceed without relying on the host equipment, enabling early detection and resolution of functional defects, preventing problems from being exposed during the host integration and debugging stage, reducing rework workload, and improving the production efficiency of the reagent sample chamber 01.
[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
