Because the blood sugar detection device that this application embodiment provided can handle the body fluid of target object and obtain the blood sugar value of target object, consequently need not the professional and use professional equipment to carry out blood sugar detection, ordinary user can adopt the blood sugar detection device that this application embodiment provided to realize detecting the blood sugar of self to the convenience of noninvasive blood sugar detection has been improved.

Please refer to fig. 3, which is a schematic structural diagram of a blood glucose detecting apparatus according to another embodiment of the present application.

Specifically, the base material layer 1111 is used to acquire a body fluid of a target object.

As an example, the substrate layer 1111 may be made of white Polyethylene Terephthalate (PET) material.

In practical applications, the target object may smear the body fluid at a target position in the substrate layer 1111, so that the substrate layer 1111 can acquire the body fluid of the target object.

Illustratively, the siphon layer 1112 may draw a quantitative amount of the body fluid of the target object to the bio-enzyme layer 1113 through a siphon reaction. In different tests, the volumes of the body fluid sucked by the siphon layer 1112 to the biological enzyme layer 1113 may be the same or different, and the specific volume of the body fluid sucked by the siphon layer 1112 to the biological enzyme layer 1113 may be set according to actual requirements, which is not particularly limited herein.

The biological enzyme can be customized based on the detection range and detection precision, and the specific selection of the type of the biological enzyme and the specific customization process of the biological enzyme are not particularly limited.

The electrode layer 1114 is used to acquire a first current signal generated by the bio-enzyme layer 1113 and transmit the first current signal to the body fluid glucose value determination unit 112.

In an alternative implementation, the electrode layer 1114 may include a reaction region 11141, a transmission region 11142, and a turn-on region 11143. Therein, the reaction zone 11141 may be connected to the transfer zone 11142, and the transfer zone 11142 may be connected to the turn-on zone 11143. The insulating layer 1115 may be used to cover the transmission region 11142 of the electrode layer 1114, providing insulating protection for the transmission region 11142.

Specifically, the reaction region 11141 may be a region where glucose in the body fluid reacts with the bio-enzyme, and the reaction region 11141 may obtain a first current signal generated by the reaction of glucose in the body fluid with the bio-enzyme and transmit the first current signal to the transmission region 11142.

The turn-on region 11143 may be connected to the body fluid glucose value determination unit 112, and the turn-on region 11143 may be configured to send a first current signal to the body fluid glucose value determination unit 112.

In this implementation, the electrode layer 1114 may include N first electrodes. For example, referring to fig. 4, fig. 4 is a schematic structural diagram of an electrode layer provided in an embodiment of the present application, and as shown in fig. 4, each first electrode may include a front portion 41, a middle portion 42, and a rear portion 43.

Specifically, the front portion 41 of the first electrode may serve as a reaction region 11141 of the electrode layer 1114, the middle portion 42 of the first electrode may serve as a transmission region 11142 of the electrode layer 1114, and the rear portion 43 of the first electrode may serve as a contact region 11143 of the electrode layer 1114.

Wherein the n reaction electrodes can be used to obtain a first current signal generated in the reaction zone 11141; the m signal electrodes may be configured to control an operation state of the body fluid glucose level determining unit 112, and specifically, when the first current signal is generated in the reaction region 11141, the m signal electrodes may control the body fluid glucose level determining unit 112 to determine the body fluid glucose level based on the first current signal; the k spare electrodes can replace the reaction electrode or the signal electrode to work when the reaction electrode or the signal electrode works abnormally. It should be noted that specific values of n, m, and k may be set according to actual requirements, and are not particularly limited herein.

In this implementation, the electrode material of the first electrode may include a silver/silver chloride paste layer, a graphene/carbon paste layer, and a PEDOT/PSS layer, where the PEDOT/PSS is an aqueous solution of a high molecular polymer and is composed of two substances, namely PEDOT and PSS.

In the first electrode, the ratio and thickness of the silver/silver chloride paste layer, the graphene/carbon paste layer and the PEDOT to PSS layer may be set according to the requirement, and are not particularly limited herein.

The signal amplification unit 1121 may be configured to receive the first current signal, perform signal amplification processing on the first current signal, and send the first current signal after the signal amplification processing to the first determination unit 1123.

It is understood that since the glucose value in the body fluid is generally low and the current value of the first current signal generated by the reaction between the glucose in the body fluid and the biological enzyme is low, the signal amplification unit 1121 performs the signal amplification process on the first current signal, so that the first determination unit 1123 can accurately determine the body fluid glucose value of the target object based on the signal-amplified first current signal.

The temperature measuring unit 1122 is configured to obtain a temperature value at the current time, and send the temperature value at the current time to the first determining unit 1123.

The current time may be any time when the body fluid glucose value determination unit 112 needs to acquire a temperature value after acquiring the first current signal.

It is understood that, since temperature affects the activity of the biological enzyme, and thus the current value of the first current signal generated by the reaction of glucose in the body fluid and the biological enzyme, the body fluid glucose value, and the blood glucose level are affected by the temperature, the temperature measurement unit 1122 can determine the body fluid glucose value more accurately by obtaining and transmitting the current temperature value to the first determination unit 1123.

First determination unit 1123 is configured to determine a body fluid glucose value based on the first current signal and the temperature value after the signal amplification processing, and send the body fluid glucose value to blood glucose value determination unit 113.

In an alternative implementation manner, since the first current signal after the signal amplification processing is an analog signal, the first determining unit 1123 may be specifically configured to perform analog-to-digital conversion on the first current signal after the signal amplification processing to obtain a current value of the first current signal, and determine the body fluid glucose value based on the current value of the first current signal and a current time temperature value. Specifically, the first determination unit 1123 may determine the body fluid glucose value based on the current value of the first current signal, the temperature value at the present moment, and the second preset function. The second preset function may be used to describe a preset corresponding relationship between the current value, the temperature value, and the body fluid glucose value.

In this implementation, the first determination unit 1123 may determine the body fluid glucose value based on the current value of the first current signal and a second preset function, based on which the second preset function may be used to describe a preset correspondence between the current value and the body fluid glucose value.

For example, in the above implementation, the second preset functions may be obtained through a plurality of experimental measurements in advance.

Blood glucose level determination unit 113 is configured to determine a blood glucose level based on the body fluid glucose level and a first preset function.

The first preset function may be used to describe a preset corresponding relationship between the body fluid glucose value and the blood glucose value, and in a specific application, the first preset function may be obtained by performing a plurality of test measurements in advance.

In an alternative implementation, the blood glucose detecting apparatus 11 may further comprise a communication unit 114 connected to the blood glucose value determining unit 113. Based on this, the blood glucose detecting apparatus 11 can establish a wireless connection with the first device 12 through the communication unit 114.

Illustratively, the communication unit 114 may be a WIFI unit, a bluetooth unit, a mobile communication unit, or the like.

Blood glucose level determination section 113 also determines the blood glucose level of the target subject and then transmits the blood glucose level of the target subject to communication section 114.

Communication section 114 can be used to transmit the blood glucose level of the target subject to first device 12 after receiving the blood glucose level of the target subject transmitted from blood glucose level determination section 113.

In an alternative implementation, the blood glucose detecting apparatus 11 may further include a storage unit 115 connected to the blood glucose value determining unit 113.

Blood glucose level determination section 113 acquires information on the target object and the determination time of the blood glucose level of the target object, and transmits the information on the target object, the blood glucose level of the target object, and the determination time of the blood glucose level of the target object to storage section 115.

The information on the target subject may be input from the target subject to blood glucose level determination section 113, and the time at which the blood glucose level of the target subject is determined by blood glucose level determination section 113 may be the time at which the blood glucose level of the target subject is determined.

Storage section 115 may be configured to store target object information, target object blood glucose level, and target object blood glucose level determination time in association with each other after receiving the target object information, the target object blood glucose level, and the target object blood glucose level determination time.

In addition, the storage unit 115 may store a preset correspondence relationship between the current value, the temperature value, and the body fluid glucose value, and a preset correspondence relationship between the body fluid glucose value and the blood glucose level.

In practical applications, the storage unit 115 may be any combination of one or more of a Read Only Memory (ROM), a Random Access Memory (RAM), a Flash Memory (Flash Memory), a USB Flash disk (USB Flash disk), and a SD Memory Card (Secure Digital Memory Card).

Blood glucose level determination section 113 also specifies the blood glucose level of the target subject and then transmits the blood glucose level of the target subject to display section 117.

Display section 117 may be configured to display the blood glucose level of the target subject after receiving the blood glucose level of the target subject. In a specific application, the display unit 117 may be a Liquid Crystal Display (LCD) or a Light-emitting diode (LED) display, and the type of the display unit 117 is not particularly limited in the embodiment of the present application.

The specific operation principle of the blood glucose detecting device according to the embodiment of the present application will be described in detail below with reference to fig. 3.

When the target object needs to detect the blood sugar of the target object, the body fluid can be smeared at the corresponding position of the substrate layer 1111 in the body fluid glucose detection test paper in the body fluid acquisition unit 111. The siphon layer 1112 can quantitatively suck the body fluid applied to the corresponding position in the base material layer 1111 to the biological enzyme layer 1113. Glucose in the body fluid and the bio-enzyme in the bio-enzyme layer 1113 react in the reaction region 11141 in the electrode layer 1114 to generate a first current signal. The reaction region 11141 may take a first current signal generated by the reaction between the glucose in the body fluid and the bio-enzyme and send the first current signal to the transmission region 11142.
