As shown in fig. 1 to 4, a temperature-controlled tray 100 according to some embodiments of the present application includes:

A tray main body 110, the tray main body 110 having a receiving space 111 for receiving the detection card 10;

the heating element 120, the heating element 120 is disposed on the tray main body 110, for heating the accommodating space 111;

A temperature probe 130 and a temperature detector 140 provided on the tray main body 110;

A controller (not shown in the drawings) electrically connected to the heating member 120, the temperature probe 130, and the temperature detector 140, the controller being configured to control the heating member 120 to stop heating if at least one of: the temperature detected by the temperature probe 130 is greater than the first temperature threshold, and the temperature detected by the temperature detector 140 is greater than the second temperature threshold; wherein the first temperature threshold is less than the second temperature threshold.

The temperature control tray 100 provided in this embodiment may be used for maintaining the temperature of the test card 10, and in some application scenarios, the test card 10 may be used for carrying a blood sample, and when the test card 10 is placed in the temperature control tray 100, the temperature of the blood sample may be controlled by the temperature control tray 100 to a preset temperature range, for example, 20-40 ℃.

The temperature-controlled tray 100 may include a tray main body 110 and a heating member 120, wherein the tray main body 110 has a receiving space 111 for receiving the detection card 10, and the heating member 120 may be used for heating the receiving space 111 to further heat the detection card 10.

In some examples, the heating member 120 may be a structure in the form of a heating plate or a heating wire, etc., and is disposed on the tray main body 110, so that the heating member 120 may be in direct contact with the test card 10 located in the accommodating space 111 to directly heat the test card 10, or the heating member 120 may be in indirect contact with the test card 10 through the tray main body 110, and indirect heating of the test card 10 may be achieved through heat conduction of the tray main body 110.

The tray main body 110 is further provided with a temperature probe 130 and a temperature detector 140, in other words, at least two temperature sensors may be provided on the tray main body 110, and these temperature sensors may be used for detecting a temperature, for example, a temperature in the accommodating space 111 may be detected, or a temperature of an environment where the temperature control tray 100 is located may also be detected, and so on.

The temperature probe 130 and the temperature detector 140 are mainly configured to control the temperature of the temperature-controlled tray 100, and particularly control the heating temperature of the detection card 10. Specifically, in this embodiment, the temperature control tray 100 further includes a controller electrically connected to the temperature probe 130, the temperature detector 140, and the heating element 120, where the controller can adjust the working state of the heating element 120 according to the temperature information detected by the temperature probe 130 or the temperature detector 140, for example, adjust the heating power of the heating element 120 or control the heating start and stop.

The controller may be an existing architecture with arithmetic processing capability, such as a micro control unit or simple logic gates, etc. The controller is electrically connected with the temperature probe 130, and on the basis of the connection structure, the controller is matched with the existing control technology, so that when the temperature detected by the temperature probe 130 is greater than the first temperature threshold, the heating element 120 is controlled to stop heating, and the detection card 10 is prevented from being heated to an excessively high temperature.

In some possible embodiments, the temperature probe 130 is a trigger type temperature sensor, and when the detected temperature is greater than the first temperature threshold, a trigger signal is sent to the controller, and the controller controls the heating member 120 to stop heating according to the trigger signal. In other possible embodiments, the temperature probe 130 may transmit an analog signal, such as a voltage signal, for characterizing the temperature to the controller in real time, and a comparator may be disposed in the controller, and two input terminals of the comparator may be respectively used to receive the voltage signal sent by the temperature probe 130, and a reference voltage may be disposed, and the reference voltage may correspond to the first temperature threshold, and when the voltage signal of the temperature probe 130 is greater than the reference voltage, that is, when the temperature detected by the temperature probe 130 is greater than the first temperature threshold, an output terminal of the comparator may output a control signal to control the heating element 120 to stop heating. The control signal may control the heating element 120 to stop heating, or may be implemented by an existing structure or control method, for example, a light pipe is provided between the heating element 120 and the power supply, and the control signal output by the comparator may control the switch to be turned off, so as to disconnect the heating element 120 from the power supply, and stop heating the heating element 120.

Of course, the above is some examples of some possible embodiments for controlling the heating element 120 by the controller according to the temperature detected by the temperature probe 130, in practical application, the above control function may be implemented by other existing means, and on the basis of the above examples, it is also possible to implement a stable control function by matching with other circuit elements, for example, a voltage stabilizing circuit or an amplifying circuit, etc., which are not described in detail herein.

Similar to the temperature probe 130, the temperature detector 140 may also be used to obtain a temperature signal, and the controller may also control the heating element 120 in conjunction with the temperature signal detected by the temperature detector 140, and the specific implementation of these controls is similar to the implementation related to the temperature probe 130, which is not repeated here.

Unlike the temperature probe 130, the controller controls the heating member 120 to stop heating when the temperature detected by the temperature detector 140 is greater than a second temperature threshold value, which is greater than the first temperature threshold value described above.

In combination with some examples, the first temperature threshold may be 30 ℃, the second temperature threshold may be 40 ℃, and in the process that the temperature of the temperature control tray 100 is gradually increased by the operation of the heating element 120, the temperature probe 130 detects that the temperature is greater than 30 ℃, the controller may control the heating element 120 to stop heating, so as to avoid heating the temperature of the detection card 10 to a higher temperature, and realize temperature control of the detection card 10.

However, when the temperature probe 130 is damaged, the temperature probe 130 does not send the collected temperature signal to the controller, and the controller is not triggered to control the heating element 120 to stop heating, at this time, the temperature of the temperature tray will continue to rise, and a specific temperature value may be obtained by the temperature detector 140. When the temperature rises to above 40 ℃, the controller can control the heating element 120 to stop heating according to the temperature signal detected by the temperature detector 140, so as to avoid the influence of the excessive temperature of the detection card 10 on the detection of the subsequent blood sample.

In some possible embodiments, by selecting or designing the existing temperature sensor, the temperature probe 130 can have relatively high sensitivity, and the temperature detector 140 has relatively high working reliability, so that when the temperature probe 130 works normally, the controller can quickly respond to the change of the heating temperature, the timeliness of temperature control is ensured, and when the temperature probe 130 is damaged, the temperature detector 140 with high reliability helps to better avoid the situation that the heating temperature is too high.

In practical applications, the controller combines a certain temperature sensor to control the heating element 120, and may not adopt a single temperature value, for example, for the temperature detected by the temperature probe 130, the controller may have a threshold value between 27 ℃ and 33 ℃, the first temperature threshold value may correspond to 33 ℃, when the temperature detected by the temperature probe 130 is greater than 33 ℃, the controller controls the heating element 120 to stop heating, and when the temperature is reduced to 27 ℃ and detected by the temperature probe 130, the controller may again control the heating element 120 to heat, so that the heating element 120 is prevented from being started and stopped too frequently. As regards the above setting and application of the temperature interval threshold, no additional improvements of the computer program are required, which belongs to the prior art.

In the present embodiment, there are two conditions, the first condition is that the temperature detected by the temperature probe 130 is greater than the first temperature threshold, the second condition is that the temperature detected by the temperature detector 140 is greater than the second temperature threshold, and the controller may control the heating member 120 to stop heating when at least one of the two conditions is satisfied. The logic may be implemented by an existing program, or may be implemented by a simple logic gate circuit design, for example, using two comparators and an or gate circuit, where the first comparator is used for outputting a high level when the temperature detected by the temperature probe 130 is greater than a first temperature threshold (an example of comparing and outputting the temperature with a reference voltage is given above, which is not described herein), the second comparator is used for outputting a high level when the temperature detected by the temperature detector 140 is greater than a second temperature threshold, and two input terminals of the or gate circuit are respectively connected to the output terminals of the two comparators, so long as the output terminal of at least one of the two comparators outputs a high level, a control signal for controlling the heating element 120 to stop operating may be sent to the output terminal, and the implementation manner of the control signal for controlling the heating element 120 to stop and start is also given above, for example, such as by a switch tube implementation, which is not described herein.

Of course, the foregoing is illustrative of some possible circuit components for implementing the controller function, and in practical application, the controller function may be implemented by simply setting a chip, such as a micro control unit, which is not illustrated herein.

The temperature control tray 100 provided by the embodiment of the application comprises a tray main body 110, a heating element 120, a temperature probe 130, a temperature detector 140 and a controller, wherein the tray main body 110 is provided with a containing space 111 for containing the detection card 10, the heating element 120 is arranged on the tray main body 110 and is used for heating the containing space 111, the controller is electrically connected with the heating element 120, the temperature probe 130 and the temperature detector 140, and the controller is used for controlling the heating element 120 to stop heating under the condition that at least one of the following conditions is met: the temperature detected by the temperature probe 130 is greater than the first temperature threshold, and the temperature detected by the temperature detector 140 is greater than the second temperature threshold; wherein the first temperature threshold is less than the second temperature threshold. In the embodiment of the application, the temperature probe 130 and the temperature detector 140 are arranged, and under the condition that the temperature probe 130 fails, the controller can still control the heating element 120 to stop heating according to the temperature detected by the temperature detector 140, so that the excessive temperature of the detection card 10 caused by continuous heating of the detection card 10 is avoided, further, the damage of a sample on the detection card 10 due to high temperature is prevented, and the accuracy of a sample analysis result is ensured.

Optionally, the temperature-controlled tray 100 further includes a switch structure disposed on the tray main body 110, the switch structure is electrically connected to the heating element 120, and the heating element 120 heats the accommodating space 111 specifically when the switch structure is closed.

In some examples, the switch structure may be a switch tube, a relay, a micro switch, or a common manual switch, etc., without specific limitation herein. Generally, the switch structure can be switched between an open state and a closed state, and when the switch structure is in the closed state, the heating element 120 can be connected to a power source, so as to heat the accommodating space 111.

In some embodiments, a variety of different types of switch structures may be used in combination to achieve a variety of functions. For example, the switch structure may include both a micro switch and a manual switch in series, the micro switch may be triggered to be closed by the detection card 10 placed in the accommodating space 111, and the heating member 120 may heat the detection card 10 in the accommodating space 111 in case that the manual switch is closed. The user may also disconnect the heating circuit, i.e. disconnect the heating element 120 from the power supply, by a manual switch if it is desired to place the test card 10 for a long period of time or if the temperature is too high.

Alternatively, as shown in fig. 1 and 3, the switch structure includes a spring 151 and a micro-switch main body 152, where the spring 151 extends to the accommodating space 111, and the micro-switch main body 152 is used to close when the spring 151 is triggered by the detection card 10 in the accommodating space 111.

In this embodiment, the switch structure may be a micro switch, which includes a spring plate 151 and a micro switch main body 152. In some embodiments, the tray main body 110 may be provided with an assembly hole, which communicates with the accommodating space 111, the micro switch main body 152 may be disposed outside the accommodating space 111, and the elastic sheet 151 may be penetrated into the accommodating space 111 from the assembly hole. When the detection card 10 is placed in the accommodating space 111, the elastic sheet 151 can be triggered, so that the micro switch main body 152 is in a closed state, and at this time, the heating element 120 can be connected with a power supply to automatically heat the detection card 10. When the detecting card 10 is taken out from the accommodating space 111, the elastic sheet 151 is restored to its original position, the micro switch main body 152 is disconnected, and the heating element 120 stops heating. In this way, the temperature control tray 100 can automatically start and stop the heating function according to whether the detection card 10 exists in the accommodating space 111.

Of course, in practical applications, the micro-switch main body 152 may be wholly or partially located in the accommodating space 111, which is not limited herein.

In this embodiment, the tray main body 110 may be mainly obtained by connecting the bracket 115 and the limiting member 118, and the two may be fixedly connected or detachably connected. The bracket 115 may have oppositely disposed first and second ends 1151, 1152, and for simplicity of illustration, the first and second ends 1151, 1152 may be longitudinally opposite ends of the bracket 115.

The first end 1151 of the bracket 115 and the limiting element 118 enclose the accommodating space 111, so that the tray main body 110 has a sufficient height to provide the accommodating space 111 for accommodating the detection card 10. The second end 1152 of the tray has a lower height from the overall view of the tray body 110, and the fixing of the temperature probe 130 and the temperature detector 140 to the second end 1152 of the tray can avoid or reduce an increase in the overall height of the temperature controlled tray 100 due to the arrangement of these components.

Optionally, as shown in fig. 1, the second end 1152 is provided with a first accommodating groove 1153, where the first accommodating groove 1153 extends through a first end surface 1154 and a second end surface 1155 of the bracket 115, where the first end surface 1154 faces the limiting element 118, and the second end surface 1155 is adjacent to the first end surface 1154 and is located at an end far from the first end portion 1151;

the temperature detector 140 is disposed in the first accommodating groove 1153.

In this embodiment, a first accommodating groove 1153 is provided at the second end 1152 of the tray, and the first accommodating groove 1153 may be used to mount the temperature detector 140, and in practical applications, the temperature detector 140 may be wholly or partially disposed in the first accommodating groove 1153.

Optionally, a receiving hole is provided on the second end surface 1155, and one end of the temperature probe 130 is embedded in the receiving hole.

In addition, one end of the temperature probe 130 is embedded in the receiving hole, and the other end may be exposed from the receiving hole so as to perform temperature detection better.

Optionally, as shown in fig. 3 and 4, the temperature-controlled tray 100 further includes a circuit board 160, where the circuit board 160 is fixed to the second end 1152 and disposed opposite the first end 1154 of the bracket 115; the controller is disposed on the circuit board 160.

The circuit board 160 is disposed opposite to the first end 1154 of the bracket 115, that is, the circuit board 160 may be disposed over components such as the temperature detector 140 and the temperature probe 130, so as to protect the components. In addition, the controller can be disposed on the circuit board 160, which is helpful for improving the integration level between the electronic components and reducing the overall volume of the temperature-controlled tray 100.

In some embodiments, there may be a certain gap between the circuit board 160 and the first end surface 1154 of the bracket 115, for example, the circuit board 160 and the bracket 115 may be connected by a support column having a certain height, or the above-mentioned micro switch main body 152 may be disposed on the first end surface 1154 of the second end plate, and the micro switch main body 152 has a certain height, and the circuit board 160 may be fixed on the upper end surface of the micro switch main body 152, or the like. The provision of the above gaps helps to provide installation space for components such as the micro-switch body 152 and may provide protection for these components by the circuit board 160.

In some embodiments, the upper end surface of the circuit board 160 may be flush or approximately flush with the upper end surface of the limiting member 118, so as to enhance the continuity of the appearance of the temperature-controlled tray 100, improve the aesthetic appearance, and also help to control the overall height of the temperature-controlled tray 100.

In some embodiments, an alarm unit, such as an audible alarm unit or an audible and visual alarm unit, may also be provided on the circuit board 160. The alarm unit is also electrically connected to the controller, and the controller can control the alarm unit to alarm when the temperature detected by the temperature probe 130 is greater than the first temperature threshold or the temperature detected by the temperature detector 140 is greater than the second temperature threshold.

The second accommodating groove 1157 may take one of two structural forms, wherein one of the two structural forms is that the second accommodating groove 1157 is communicated with the accommodating space 111, so that the heating element 120 can be directly contacted with the detection card 10 in the accommodating space 111, and further the heating efficiency of the detection card 10 is improved; another structural form is that the second accommodating groove 1157 is opposite to the accommodating space 111, and the second accommodating groove 1157 and the accommodating space are not directly communicated, so that heat generated by the heating element 120 can be transferred to the detection card 10 through the tray to heat the detection card 10, and the structural form is beneficial to improving the overall strength of the temperature control tray 100, and meanwhile, the heating uniformity of the detection card 10 can be improved.

Optionally, as shown in fig. 3 and 4, an end surface of the limiting member 118, which is far away from the first end surface 1154 of the bracket 115, is provided with a detection hole 1181, and the detection hole 1181 is communicated with the accommodating space 111.
