The subject matter herein generally relates to healthcare, and particularly to a method for medical detection, a medical detection device, and a storage medium.
Medical detection devices are widely used, the medical detection device allows users to measure physiological parameters themselves, so as to reduce the number of times the users go to the hospital. Test strips are usually used while detecting the physiological parameters, for example, the blood glucose meter detects blood glucose of blood on the test strips by electrode measurement. However, the measurement of physiological parameters through the test strips can be easily affected by ambient temperature, which causes measurement errors and affects the accuracy of measurement results.

In one embodiment, the storage device 20 can include various types of non-transitory computer-readable storage mediums. For example, the storage device 20 can be an internal storage system, such as a flash memory, a random access memory (RAM) for temporary storage of information, and/or a read-only memory (ROM) for permanent storage of information. The storage device 20 can also be an external storage system, such as a hard disk, a storage card, or a data storage medium. The processor 10 can be a central processing unit (CPU), a microprocessor, or other data processor chip that performs functions of the medical detection device 1.
In response to an instruction generated by user operation, the temperature sensor 40 is controlled to detect the temperature of the test strip 30, the processor 10 is configured to obtain the temperature of the test strip 30 from the temperature sensor 40. The instruction may be a detection instruction for physiological parameters.
In one embodiment, the medical detection device 1 defines a slot 90 for receiving the test strip 30, and the temperature sensor 40 is arranged in the slot 90. The temperature sensor 40 may be an infrared temperature sensor or a contact temperature sensor.
In one embodiment, the display device 80 is a touch screen. The user can input the detection instruction by performing a touch operation on the display device 80, and insert the test strip 30 into the slot 90 before collecting the user's blood using the test strip 30.
In one embodiment, the medical detection device 1 can automatically detect whether the test strip 30 is inserted into the slot 90, and when detecting that the test strip 30 is inserted into the slot 90, the temperature sensor 40 can automatically detect the temperature of the test strip 30. In other embodiments, the user can input a temperature detection instruction by performing a touch operation on the display device 80, and the processor 10 controls the temperature sensor 40 to detect the temperature of the test strip 30 in response to the temperature detection instruction.
The processor 10 is further configured to determine a measurement error rate k corresponding to the detected temperature of the test strip 30 according to a relationship between the temperatures and the measurement error rates of the physiological parameter.
In one embodiment, the storage device 20 stores a table for recording the relationship between the temperatures and the measurement error rates of at least one physiological parameter. The at least one physiological parameter includes blood sugar level, uric acid level, cholesterol level, and other physiological parameter.
For example, when the detection instruction input by the user is a detection instruction of blood sugar, and the temperature sensor 40 detects that the temperature of the test strip is 40° C., it is determined that the measurement error rate of the blood sugar is −8.45% according to the relationship between the temperatures and the measurement error rates.
The processor 10 is further configured to measure at least one physiological parameter based on the blood on the test strip 30, when the medical detection device 1 receives the test strip 30 that carries the blood of the user, that is, the medical detection device receives the test strip and detects presence of blood on the test strip, and obtains the measurement value of the at least one physiological parameter.
In one embodiment, after the temperature of the test strip 30 is detected, the user can use the test strip 30 to collect blood, and insert the test strip 30 that carries the blood into the slot 90. The medical detection device 1 can automatically detect whether the test strip 30 that carries the blood is inserted into the slot 90, and when it is detected that the test strip 30 that carries the blood is inserted into the slot 90, the processor 10 measures the at least one physiological parameter based on the blood on the test strip 30, and obtains the measurement value of the at least one physiological parameter.
In one embodiment, the test strip 30 defines electrodes and enzymes, the enzymes is used for chemically reacting with the glucose, the uric acid, or the cholesterol in the blood.
In detail, the medical detection device 1 can provide various types of test strips, the resistances of the various types of test strips are the same. If the test strip 30 is a strip for blood glucose detection, the enzymes can be glucose dehydrogenase, which can chemically react with the glucose in the blood. If the test strip 30 is a strip for uric acid detection, the enzymes can be uric acid oxidase, which can chemically react with uric acid in the blood. If the test strip 30 is a strip for cholesterol detection, the enzymes can be cholesterol oxidase, which can chemically react with the cholesterol in the blood. Understandably, the test strip 30 can also be set with other enzymes according to other measurable physiological parameters.
In one embodiment, the processor 10 receives signals transmitted by the electrode, the signals generated by the chemical reaction between the enzymes and at least one of the glucose, uric acid, or cholesterol in the blood, and converts the received signals into at least one of the blood glucose concentration, the uric acid concentration, or cholesterol concentration.
In detail, when measuring the blood glucose concentration of the blood of the user, the blood glucose detector 50 receives the signals generated by the chemical reaction between the glucose dehydrogenase and the glucose in the blood, and converts the signals to the blood glucose concentration. When measuring the uric acid concentration of the blood of the user, the uric acid detector 60 receives the signals generated by the chemical reaction between the uric acid oxidase and the uric acid in the blood, and converts the signals to the uric acid concentration. When measuring the cholesterol concentration of the blood of the user, the cholesterol detector 70 receives the signals generated by the chemical reaction between the cholesterol oxidase and the cholesterol in the blood, and converts the received signals into the cholesterol concentration.
The processor 10 is further configured to compensate for the measurement value according to the measurement error rate, and obtain a correction value b of the physiological parameter.
In one embodiment, the correction value b=a−a*k. For example, if the measurement value of the blood glucose concentration is 9 mmol/L, and the measurement error rate is −8.45%, the correction value b is 9.7605 mmol/L.
It should be noted that, the resistance of all test strips is the same. Since the resistance of the test strip will change with the temperature of the environment and the test strip itself, the current received by the medical detector as an indicator will not be accurate, thus affecting the detection results. Therefore, it is necessary to correct the measurement results so as to improve the accuracy of medical conclusions.
The processor 10 is further configured to display the corrected value of the physiological parameter on the display device 80.
In one embodiment, during the production process of the medical detection device 1, the processor 10 is further configured to measure the physiological parameters of different blood samples at different temperatures using a plurality of test strips that carry different blood samples, and obtain a plurality of measurement values of the physiological parameter, establish a table and record the relationship between the measurement values at different temperature and the measurement values of the physiological parameter according to the plurality of measurement values and the different temperatures, and calculate the measurement error rate k corresponding to each temperature according to the average value a1 of the plurality of measurement values corresponding to each temperature and the average value a2 of the plurality of measurement values corresponding to room temperature as a baseline. The measurement error rate k=(a1−a2)/a2, and the relationship between the temperatures and the measurement error rates is stored in the storage device 20.
For example, the temperature of the test strip 30 can be controlled by being placed in an incubator, and then the blood glucose concentrations in six samples of blood can be measured. Referring to
