[0034] The first embodiment of the present invention relates to a temperature control method for a sample detection device, which is applied to the sample detection device, and the sample detection device is, for example, a urine detection device, a saliva detection device, a blood detection device, a sweat detection device, etc.; in this embodiment and subsequent embodiments, the sample detection device is taken as an example of a urine detection device, which is used to be assembled on the inner wall of a toilet, and can collect and detect urine.

[0035] The specific process of the temperature control method of the sample detection device of this embodiment is as follows Figure 1 shown.

[0036] Step 101, obtaining temperature parameters associated with a sample detection device.

[0037] Specifically, when the sample detection device is not in the sampling and detection process, for example, the sample detection device enters a dormant state when not used for a long time, when the sample detection device is in the dormant state, some sensors or signal receiving devices are still in working state, so that the sample detection device can still periodically obtain the temperature parameters associated with the sample detection device.

[0038] Step 102: Determine whether the sample detection device needs to be emptied based on the temperature parameter. If yes, proceed to step 103; if no, return to step 101.

[0039] Step 103, controlling the draining of liquid from the pipeline of the sample detection device.

[0040] Specifically, after obtaining the relevant temperature parameters each time, the sample detection device will determine whether the sample detection device is at risk of being damaged by freezing based on the temperature parameters obtained this time. If it is determined that the sample detection device is not at risk of being damaged by freezing, it returns to step 101, continues to obtain temperature parameters and executes the judgment step of step 102; if it is determined that the sample detection device is at risk of being damaged by freezing, it is determined that the sample detection device needs to be emptied, and the liquid in the pipeline of the sample detection device is controlled to be emptied, and the liquid is, for example, a cleaning liquid (for example, clean water), a reaction waste liquid, etc., that is, all the liquid in the pipeline of the sample detection device is controlled to be emptied to avoid the subsequent abnormal situation such as the temperature dropping to the freezing point, which causes the liquid in the pipeline to solidify and increase the volume and damage the pipeline. The pipeline includes, but is not limited to, the sampling flow channel between the sample detection device switching valve and the peristaltic pump, the flow channel between the reaction chamber for sample detection and the waste liquid outlet, etc.

[0041] In one example, the sample detection device is provided with a liquid storage chamber for storing a cleaning liquid for cleaning the pipeline; after step 103, the method further includes:

[0042] Step 104, controlling the emptying of the cleaning liquid in the liquid storage chamber of the sample detection device.

[0043] Specifically, the liquid storage chamber in the sample detection device generally stores cleaning liquids such as clean water, so as to promptly clean a small amount of droplets or foreign matter remaining in the pipeline of the sample detection device after each sampling and detection; when the sample detection device needs to be emptied, the cleaning liquid in the liquid storage chamber of the sample detection device will also be emptied at the same time as the liquid in the pipeline is emptied, so as to avoid the subsequent abnormal situation such as the temperature dropping to the freezing point, which will cause the liquid in the liquid storage chamber to solidify and increase the volume and damage the liquid storage chamber.

[0044] The present embodiment provides a temperature control method for a sample detection device, which first obtains a temperature parameter associated with the sample detection device, then determines whether it is necessary to perform an emptying operation on the sample detection device based on the obtained temperature parameter, and when it is determined that the sample detection device needs to be emptied, timely controls the emptying of the liquid in the pipeline of the sample detection device, thereby being able to timely empty the liquid in the pipeline of the sample detection device when a temperature abnormality may cause a risk of damage to the sample detection device, thereby avoiding the subsequent abnormal conditions such as the temperature dropping to the freezing point or the temperature rising beyond the range, which causes the volume of the liquid in the pipeline to increase and damage the pipeline, thereby avoiding irreversible damage to the pipeline of the sample detection device caused by a low temperature or high temperature environment, and ensuring the safety of the sample detection device working in a wider temperature range; at the same time, the liquid in the pipeline is emptied only when there is a risk of overheating or freezing damage, thereby reducing the number of times the sample detection device performs an emptying operation, increasing the service life of related equipment in the sample detection device, expanding the operating temperature range of the sample detection device, optimizing the controllability of the internal temperature management of the sample detection device, and improving the accuracy of the temperature management of the sample detection device.

[0045] The second embodiment of the present invention relates to a temperature control method for a sample detection device. Compared with the first embodiment, the main improvement of this embodiment is that: this embodiment provides an implementation method for determining whether the sample detection device needs to be emptied based on temperature parameters.

[0046] In this embodiment, the temperature parameter includes any one or any combination of the following: the ambient temperature of the environment in which the sample detection device is located, the regional air temperature where the sample detection device is located, the internal gas temperature of the sample detection device when it is in a non-working state, and the device temperature of the detection device when the sample detection device is in a non-working state. The non-working state refers to the sample detection device not being in the process of sampling, detection, cleaning, etc.

[0047] In this embodiment, the ambient temperature of the environment in which the sample detection device is located can be obtained through an electronic device, a temperature sensor, etc. wirelessly connected to the sample detection device, or through an ambient temperature sensor set on the wireless power supply device of the sample detection device. The ambient temperature can be the indoor temperature of the room where the sample detection device is placed; the regional air temperature of the location where the sample detection device is located can be obtained through an electronic device wirelessly connected to the sample detection device, or the sample detection device obtains and queries it through a wireless network; the internal gas temperature of the sample detection device when it is in a non-working state can be collected by an internal temperature sensor set inside the sample detection device, and the internal temperature sensor has no contact with the detection device of the detection device; the device temperature of the detection device when the sample detection device is in a non-working state can be obtained by a device temperature sensor set in contact with the detection device of the sample detection device, for example, the device temperature sensor is set in the reaction chamber of the detection device.

[0048] The following is an example in which the temperature parameters include the ambient temperature of the environment in which the sample detection device is located, the regional air temperature where the sample detection device is located, the internal gas temperature when the sample detection device is in a non-working state, and the device temperature of the detection device when the sample detection device is in a non-working state.

[0049] The specific process of the temperature control method of the sample detection device of this embodiment is as follows Figure 2 shown.

[0050] Step 201, obtaining the temperature parameter associated with the sample detection device, is substantially the same as step 101 in the first embodiment and will not be described in detail herein.

[0051] Step 202 includes the following sub-steps:

[0052] Sub-step 2021, determine whether the temperature parameter meets the first preset condition, the first preset condition is that the regional air temperature is lower than the ambient temperature, the ambient temperature and the internal gas temperature are both within the first temperature range and the device temperature is lower than the first temperature threshold, and the lower limit of the first temperature range is greater than the first temperature threshold. If yes, proceed to step 203; if no, proceed to sub-step 2022.

[0053] Sub-step 2022, determining whether the temperature parameter satisfies the second preset condition, the second preset condition being that the ambient temperature is lower than the internal gas temperature, the ambient temperature is within the second temperature range and the device temperature is lower than the second temperature threshold, the lower limit of the first temperature range is higher than the upper limit of the second temperature range, and the first temperature threshold is lower than the second temperature threshold. If yes, proceed to step 203; if no, proceed to sub-step 2023.

[0054] Sub-step 2023, determining whether the temperature parameter satisfies a third preset condition; the third preset condition is that the ambient temperature is within a third temperature range, the lower limit of the second temperature range is greater than the upper limit of the third temperature range, and the upper limit of the third temperature range is less than or equal to 5. If yes, proceed to step 203; if no, proceed to sub-step 2024.

[0055] Sub-step 2024, determining whether the device temperature is greater than or equal to a third temperature threshold, the third temperature threshold being greater than an upper limit of the first temperature range. If yes, proceed to step 203; if no, proceed to sub-step 2025.

[0056] Specifically, after obtaining the temperature parameters each time, the sample detection device determines that the temperature parameters meet the first preset condition when the regional air temperature is lower than the ambient temperature, the ambient temperature is within the first temperature range, the regional air temperature is within the first temperature range, and the equipment temperature is lower than the first temperature threshold, and determines that the sample detection device needs to be emptied, and enters step 203 to control the emptying of the liquid in the pipeline of the sample detection device; wherein the lower limit value of the first temperature range is greater than the first temperature threshold.

[0057] If the temperature parameter does not meet the first preset condition, it is determined whether the temperature parameter meets the second preset condition. When the ambient temperature is lower than the internal gas temperature, the ambient temperature is within the second temperature range, and the device temperature is lower than the second temperature threshold, it is determined that the temperature parameter meets the second preset condition, and it is determined that the sample detection device needs to be emptied. Step 203 is entered to control the emptying of the liquid in the pipeline of the sample detection device; wherein, the lower limit value of the first temperature range is greater than the upper limit value of the second temperature range, and the first temperature threshold is less than the second temperature threshold.

[0058] If the temperature parameter does not meet the second preset condition, it is determined whether the temperature parameter meets the third preset condition. When the ambient temperature is within the third temperature range, that is, when the ambient temperature is too low, it is determined that the temperature parameter meets the third preset condition, and it is determined that the sample detection device needs to be emptied. Step 203 is entered to control the emptying of the liquid in the pipeline of the sample detection device. The lower limit value of the second temperature range is greater than the upper limit value of the third temperature range, and the upper limit value of the third temperature range is less than or equal to 5.

[0059] If the temperature parameter does not meet the third preset condition, it is determined whether the device temperature of the sample detection device is greater than or equal to the third temperature threshold. If the device temperature of the sample detection device is greater than or equal to the third temperature threshold, it means that the temperature of the sample detection device is too high, and it is determined that the sample detection device needs to be emptied, and the process proceeds to step 203 to control the emptying of the liquid in the pipeline of the sample detection device to avoid damage to the pipeline due to an increase in the volume of the liquid in the pipeline caused by excessive temperature; if the device temperature is less than the third temperature threshold, the process proceeds to sub-step 2025. The third temperature threshold is greater than the upper limit of the first temperature range.

[0060] For example, the first temperature range is 10-35°C, the second temperature range is 5-9°C, the first temperature threshold is 5°C, the second temperature threshold is 10°C, the third temperature threshold is 36°C, and the third temperature range is -20-5°C, as shown in the following table. After obtaining the temperature parameters, the sample detection device can query the following table to obtain the operations to be performed.

[0061] Table 1

[0062]

[0063] In one example, the temperature parameter also includes: the temperature of the outer surface of the outer shell of the sample detection device and the temperature of the inner surface of the outer shell of the sample detection device. For example, temperature sensors are installed on both sides of the outer shell of the sample detection device to obtain the temperature of the outer surface and the temperature of the inner surface of the outer shell of the sample detection device.

[0064] After sub-step 2024, the method further includes:

[0065] Sub-step 2025, determining whether the absolute value of the difference between the temperature of the outer surface and the temperature of the inner surface of the outer shell of the sample detection device is greater than the fourth temperature threshold, and the ambient temperature or the regional temperature is less than or equal to 0 degrees. If yes, proceed to step 203; if no, return to step 201.

[0066] Specifically, when the temperature parameters do not meet the above-mentioned first preset condition to the third preset condition, and the device temperature is less than the third temperature threshold, the difference between the temperature of the outer surface and the temperature of the inner surface of the outer shell of the sample detection device is calculated, and it is determined whether the absolute value of the difference is greater than the fourth temperature threshold (for example, 10°C). If the difference is greater than the fourth temperature threshold, it is determined whether the ambient temperature or the regional air temperature is less than or equal to 0 degrees. When the ambient temperature or the regional air temperature is less than 0 degrees, it is determined that the sample detection device needs to be emptied, and step 203 is entered to control the emptying of the liquid in the pipeline of the sample detection device.

[0067] It should be noted that Figure 2 The execution order of sub-steps 2021 to 2024 is only schematically described, and this embodiment does not impose any limitation on this.

[0068] Step 203, controlling the liquid in the pipeline of the sample detection device to be emptied, is substantially the same as step 103 in the first embodiment and will not be described in detail here.

[0069] Step 204, controlling the draining of the cleaning liquid in the liquid storage chamber of the sample detection device, is substantially the same as step 104 in the first embodiment and will not be described in detail herein.

[0070] The third embodiment of the present invention relates to a sample detection device, which may be, for example, a urine detection device, a saliva detection device, a blood detection device, a sweat detection device, etc. In this embodiment and subsequent embodiments, the sample detection device is taken as a urine detection device as an example.

[0071] Please refer to Figure 3 and Figure 4 The sample detection device includes: an outer shell 1, a detection device 2 arranged in the outer shell 1, and a controller 3. The controller 3 is connected to the detection device 2 for communication. The detection device 3 can detect the sample through an optical sensor.

[0072] The controller 3 is used to obtain the temperature parameters associated with the sample detection device.

[0073] The controller 3 is further used to determine whether it is necessary to perform an evacuation operation on the sample detection device based on the temperature parameter.

[0074] The controller 3 is also used to control the emptying of liquid in the pipeline of the detection device 1 of the sample detection device when it is determined that the sample detection device needs to be emptied.

[0075] In one example, a liquid storage chamber (not shown in the figure) for storing cleaning liquid for cleaning pipelines is provided in the sample detection device; the controller 3 is also used to control the emptying of the cleaning liquid in the liquid storage chamber in the sample detection device when controlling the emptying of the liquid in the pipeline of the sample detection device.

[0076] Since the first embodiment corresponds to this embodiment, this embodiment can be implemented in conjunction with the first embodiment.

In order to reduce repetition, they are not repeated here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied in the first embodiment.

[0077] The fourth embodiment of the present invention relates to a sample detection device. Compared with the third embodiment, the main improvement of this embodiment is that: this embodiment provides an implementation method for determining whether the sample detection device needs to be emptied based on temperature parameters.

[0079] The controller 3 is used to obtain the internal gas temperature of the sample detection device when it is in a non-working state through the internal temperature sensor 4.

[0080] The controller 3 is used to obtain the device temperature of the detection device 2 when the sample detection device is in a non-working state through the device temperature sensor 5. For example, the device temperature sensor 5 is set in the reaction chamber of the detection device 2 to obtain the temperature of the reaction chamber as the device temperature.

[0081] The controller 3 is used to obtain the ambient temperature of the environment in which the sample detection device is located and the regional air temperature where the sample detection device is located.

[0082] The ambient temperature of the environment in which the sample detection device is located can be obtained through electronic equipment, temperature sensors, etc. wirelessly connected to the sample detection device, or through an ambient temperature sensor set on the wireless power supply device of the sample detection device. The ambient temperature can be the indoor temperature of the room where the sample detection device is placed.
