Description

Technical Field

[0001] The present invention relates to the field of instruments and meters, and in particular to an electrochemical detection device and an electrochemical detector. Background Art

[0002] In the field of electrochemistry, the analysis of the reaction degree and stability of the stock solution is used to reflect the characteristics of the stock solution, and then developed into a method for detecting body fluids to reflect the human physical condition. It is widely used in the field of in vitro testing. The shortcomings of the use of in vitro testing in the laboratory are that the operation process is too complicated, the threshold of instruments and equipment is high, and specialized experimenters are required to complete the test. This has led to the rapid development of portable, civilian-grade in vitro detectors or screening instruments.

[0003] As people's health awareness continues to improve and the pace of life continues to accelerate, people have more and more demands for rapid health checks. Blood glucose and uric acid concentration detectors can complete the test within a few minutes, and can quickly diagnose and screen patients and detect the severity of their symptoms. The accuracy of the test results has been improved to the medical level, which has been recognized by medical workers and consumers, and is widely used in medical testing and civilian self-testing.

[0004] Mobile terminals such as smart phones have gradually penetrated and been widely used in people's daily lives. People's requirements for smart phones are getting higher and higher. Smart phones have become a new computing platform that is popular with the public after PCs. The original charging interface on the mobile phone has gradually evolved into a data communication interface. Its functions have become more and more powerful. It is completely the same as the USB interface on the computer. It can be used to mount some devices and complete data exchange and power supply functions.

[0005] At present, 1. When a device needs to interact with a mobile phone for data, a data cable is often used or a fixed male connector on the device is connected to the mobile phone to complete data interaction or power supply. When using a data cable for data transmission, the data cable needs to be carried separately, which not only takes up space and is easy to get tangled, but also often pulls the data cable, causing the tail end to break, resulting in poor contact or short circuit, or even damage to the mobile phone. When the device itself comes with a fixed male connector, since the data interface position of each model of mobile phone is different, when the device and the mobile phone are plugged together, it will be inconvenient to hold the mobile phone, it is easy to accidentally bump into it, causing damage to the male connector, or it cannot be connected at all, making it impossible to use the device well.

[0006] 2. Ordinary portable electrochemical detectors include the following parts: test paper slot, test sampling module, data processing module, button setting module, data display module, data transmission module, and power supply module. Among them, the data display module, power supply module, and button setting module account for more than half of the production cost of the instrument. Even so, it is difficult to optimize the human-computer interaction to the level of human-computer interaction of mobile phones, resulting in poor user experience and high production costs during the use of traditional electrochemical detectors. The batteries in the power supply module, whether button batteries, dry batteries or rechargeable batteries, will pollute the environment during production, use and scrapping, and increase the cost of use during use.

[0007] 3. Currently, intelligent electrochemical detectors on the market use the following communication methods to transmit test data to remote servers: Bluetooth, WIFI, GPRS, 3G, 4G, and 5G. These communication methods have high power and cause more electromagnetic pollution. It is well known that electromagnetic radiation can have an impact on human health. However, when the communication uses the traffic of the built-in tariff card for data exchange, new tariffs will be generated during use, and the cost of use is relatively high.

DETAILED DESCRIPTION

[0039] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] like Figure 1-11 As shown, the electrochemical detection device includes a housing 1 and a data transmission male connector 2 that cooperates with a data transmission interface of a mobile terminal 3. The housing 1 is provided with a test paper slot 11, wherein the housing 1 is provided with a slide groove 12, the data transmission male connector 2 is provided with a conducting portion, the slide groove 12 is correspondingly provided with a conductive portion that contacts the conducting portion, the slide groove 12 has a certain length, and the data transmission male connector 2 moves along the slide groove 12. The conductive portion is located at the bottom end surface inside the slide groove 12, and the conductive portion can be reliably connected with the conductive portion on the data transmission male connector 2, so that the data transmission male connector 2 can slide left and right along the slide groove 12.

[0041] The shape and size of the shell 1 are not limited. Specifically, the shell 1 can adopt a rectangular parallelepiped structure with a length of 70mm, a width of 7mm, and a height of 20mm. The corners of the shell 1 adopt a rounded structure. The data transmission male connector 2 is located at the end face of the shell where the length is 70mm*7mm, and slides along the side length where the length is 70mm. The mobile terminal 3 includes personal computing devices such as mobile phones, tablet computers, or PCs. For example, when the electrochemical detection device is inserted into a tablet computer or a PC, the data transmission interfaces such as USB interfaces, serial ports, infrared interfaces, and Bluetooth interfaces located on one side of the tablet computer or the PC are relatively concentrated. When several of the interfaces are used, there is not enough insertion space. In addition, the data transmission male connector without a mobile function has a certain volume, which further limits the insertion space, resulting in the inability to insert an adapted interface, and the application is inconvenient. The data transmission male connector that can slide left and right can avoid the situation of space limitation and facilitate the application of several data transmission interfaces at the same time.

[0042] Further, the conducting part includes a plurality of electrode contacts 21, and the conductive part includes a plurality of copper sheets 22. The electrode contacts 21 are independent of each other, and the copper sheets 22 are independent of each other. Figure 5. Preferably, the number of electrode contacts 21 is the same as the number of copper sheets 22. Specifically, the electrode contacts 21 are arranged at equal intervals, and the copper sheets 22 are arranged at equal intervals. In this embodiment, the conductive portion includes four electrode contacts 21, wherein two electrode contacts 21 are used for power supply and two electrode contacts 21 are used for data transmission. Specifically, the conductive portion includes four copper sheets, and the electrode contacts 21 correspond to the copper sheets 22 one by one. Specifically, the copper sheet 22 is in the shape of a long strip, and the length of the copper sheet 22 covers the length of the bottom end surface of the slide groove 12.

[0043] As a specific implementation, the conducting part is made of elastic material, which provides a more secure contact and avoids poor contact caused by deformation.

[0044] As an implementation method, Figure 3-4 As shown, the housing 1 is provided with a receiving portion for receiving the data transmission male connector 2 and a clamping assembly 14 for clamping the data transmission male connector 2 .

[0045] As a specific implementation method, Figure 3-11 As shown, the clamping assembly 14 includes a button 141 and a buffer spring 142. The housing 1 is provided with a channel 143 for the button 141 to pass through. One end of the buffer spring 142 is connected to the housing 1, and the other end is connected to the button 141. The button 141 is provided with an insertion portion 1411 adapted to the data transmission male connector 2. The insertion portion 1411 is provided with a buckle 1422. The data transmission male connector 2 is provided with a bayonet 1423 that cooperates with the buckle 1422. Specifically, the insertion portion 1411 is a groove structure, see Fig.10 , or it can also be a through-hole structure, see Fig.11 The buckle 1422 is fixed to the inner wall of the insertion portion 1411 .

[0046] As a specific implementation method, Figure 4 and Fig. 9As shown, the accommodating portion includes an accommodating cavity 131 and a reset spring 132 arranged at the bottom of the slide 12, and the reset spring 132 is connected to the bottom of the accommodating cavity 131. The position of the accommodating cavity 131 is not limited, and can be located at any position at the bottom of the slide 12, as long as the data transmission male head 2 can fall into the accommodating cavity 131 when the data transmission male head 2 slides to the position where the accommodating cavity 131 is located. For example, when the accommodating cavity 131 is located in the middle position of the slide 12, the conductive parts on both sides of the slide 12 need to be disconnected. At this time, the conductive parts on both sides of the slide 12 are connected to the circuit board 15 through the wire 151 respectively, and at this time, the channel 143 is located at the end face where 20mm*70mm is located. Preferably, the accommodating cavity 131 is located at the end of the slide 12, so that the conductive part does not need to be disconnected, and the button 141 is inserted into the channel 143 from the side of the housing 1, that is, the channel 143 is located at the end face where 20mm*7mm is located, and the thickness of the housing 1 meets the setting of button insertion and is beautiful. In another specific embodiment, the slide groove is a placement groove, the placement groove has a limited length, and only accommodates a data transmission male head 2 of a volume. The accommodating portion is located at one end of the placement groove. When the data transmission male head 2 is hidden, the data transmission male head 2 moves to the left or right and moves down to the accommodating cavity 131. Fig.12 Specifically, the placement groove may be located in the middle or on both sides of the housing 1, and the accommodating portion is located on the left or right side of the placement groove.

[0047] The initial setting state of the clamping assembly 14 may include two kinds, one is that the insertion portion 1411 of the button 141 is just located above the accommodating cavity 131, at this time, the buffer spring 142 is in the original length state, when the data transmission male connector 2 is hidden, the data transmission male connector 2 moves down through the insertion portion 1411, the reset spring 132 is compressed, the buckle 1422 on the insertion portion 1411 cooperates with the bayonet 1423 on the data transmission male connector 2 to clamp the data transmission male connector 2. The other is that since the accommodating volume of the accommodating cavity 131 is larger than the volume of the data transmission male connector 2, the insertion portion 1411 of the button 141 does not need to be aligned with the accommodating cavity 131, when hidden, the button 141 needs to be moved, the buffer spring 142 is compressed or stretched, so that the insertion portion 1411 is aligned with the data transmission male connector 2, and then the data transmission male connector 2 moves down through the insertion portion 1411, the reset spring 132 is compressed, and the buckle 1422 on the insertion portion 1411 cooperates with the bayonet 1423 on the data transmission male connector 2 to achieve the purpose of clamping. When the data transmission male connector 2 is extended, the button 141 is pushed inwards, and the data transmission male connector 2 pops out.

[0048] As a specific implementation method, Figure 3 As shown, the test paper slot 11 is located on the end surface opposite to the data transmission male connector 2, or the test paper slot 11 is located on the end surface adjacent to the data transmission male connector 2. The test paper slot 11 is arranged on the end surface opposite to the data transmission male connector 2 or on the end surface adjacent to the data transmission male connector 2, so as to facilitate the insertion of the test paper 4 into the test paper slot 11.

[0049] As a specific implementation, a circuit board 15 and a single-chip microcomputer are provided inside the housing 1, the test paper slot 11 is welded to the circuit board 15, the single-chip microcomputer is welded to the circuit board 15, the bottom end surface of the slide 12 is provided with a slideway group that fits the conductive part, the slideway group includes a plurality of slideways 121, the slideways 121 are independent of each other, the conductive part is located above the slideway 121, the circuit board 15 is connected to the slideway 121 through a wire 151, and the slideway 121 is made of copper, see Figure 7 . In this embodiment, the copper sheet 22 has a certain thickness, and the copper sheet 22 is in contact with the slide 121. The copper sheet 22 can be taken out or put in, and the number of copper sheets 22 can be arbitrarily set according to the detection needs of the detector. When the copper sheet 22 is taken out, the electrode contact 21 is away from the slide 121, and the electrode contact 21 is disconnected from the slide 121. Moreover, if the copper sheet 22 is damaged, only the copper sheet 22 is replaced without replacing the detection device. In this embodiment, the shell 1 is composed of two parts, and the two parts can be connected by snapping to facilitate the removal or placement of the copper sheet and the data transmission male head. The two parts refer to dividing the shell into two parts in a direction parallel to the side length of 70 mm. As another specific embodiment, the bottom end face in the slide 12 is directly in contact with the conductive part, and the circuit board 15 is directly connected to the conductive part through the wire 151, see Figure 5 In this embodiment, the copper sheet 22 cannot be taken out or put in, but the conductive part is fixed to the bottom of the slide slot 12, and the placement of the conductive part is more stable. The circuit board 15 is used to sample the reaction result data of the sample to obtain the sampled data, and the single-chip microcomputer is used to process the sampled data. This embodiment uses a low-power MSP430 single-chip microcomputer as the main control chip, connects the test sample to the circuit through the test paper 4 through the test paper slot 11, and samples the sample reaction results through a voltage regulator, a transimpedance amplifier circuit and a 16-bit DAC. The sampled values ​​are calculated and sorted by the single-chip microcomputer to obtain the final data.

[0050] The electrochemical detector includes an electrochemical detection device and a mobile terminal 3. The mobile terminal 3 has a data transmission interface that cooperates with a data transmission male connector 2. Fig.13 .

[0051] As a specific implementation, the data transmission interface of the mobile terminal 3 can adopt a type-c interface, or a data transmission interface such as micro-usb, mini-usb, lightning, etc. At present, the intelligent electrochemical detectors on the market use the following communication methods to transmit test data to the remote server: Bluetooth, WIFI, GPRS, 3G, 4G, 5G. These communication methods all have electromagnetic pollution, and a large amount of electronic radiation will affect human health. The configuration is complicated during use, resulting in a high threshold for use. Some communication methods use the flow of the built-in rate card for data exchange, which will generate new charges during use. However, the present invention solves the above problems. The communication adopts a communication method directly connected to the mobile terminal 3. During use, you only need to insert the present invention into the data transmission interface of the mobile terminal 3 to automatically wake up the mobile terminal APP and start normal measurement without complicated operations. The measurement data is transmitted to the server only through the flow in the mobile terminal 3 or the mobile terminal WIFI, and basically no flow charges will be generated.

[0052] The test results are transmitted to the mobile terminal APP through the external retractable sliding data transmission male connector 2 of the present invention connected to the data transmission interface of the mobile terminal 3 for further processing, display and other operations. The APP on the mobile terminal 3 also sends the test results to the remote server through the mobile terminal 3 network for data statistics. The power used in the working process of the present invention is provided by the OTG reverse charging function of the mobile terminal 3.

[0053] As a specific implementation, the mobile terminal has a button setting module, a data display module, a data transmission module and a power supply module. The current electrochemical detector human-computer interaction part, power supply part, data transmission part, and button part account for more than half of the production cost of the instrument. Even so, it is difficult to optimize the human-computer interaction to the human-computer interaction level of the mobile terminal 3, resulting in poor user experience and high production costs during the use of traditional electrochemical detectors; the present invention uses a mobile terminal APP to replace the button setting module, data display module, data transmission module and power supply module of the electrochemical detector, and uses the mobile terminal for power supply, which reduces the production cost of the electrochemical detector to less than half of the original cost, and improves the human-computer interaction and use experience to the level of the mobile terminal 3, reducing battery use and reducing environmental pollution.

[0054] Taking a mobile phone as an example, the working process of the electrochemical detector is: when the stock solution test is required, first pop out the data transmission male connector 2 of the electrochemical detector, slide it to the appropriate position, and insert it into the data transmission interface of the mobile phone. The supporting APP in the mobile phone is automatically awakened, and the APP interface prompts to insert the test paper 4, and then insert the prepared test paper into the electrochemical detector. After the detector responds, it will prompt to drop the liquid and send the instruction to the mobile phone APP. The mobile phone APP will prompt to drop the liquid and drop the prepared test sample into the test paper. The detector will send the countdown instruction to the mobile phone APP to start the test countdown. After the countdown is completed, the test results will be sent by the detector to the mobile phone APP. The APP displays the test results and then sends the test results to the server through the mobile phone network. The test is completed, the mobile phone APP prompts to unplug the detector, and the mobile phone enters the pre-test state.
