Abstract
Description
Technical Field
[0001] This utility model belongs to the field of in vitro diagnostic equipment technology, specifically relating to in vitro diagnostic equipment for querying measurement history records. Background Technology
[0002] With the advancement of technology and social development, an increasing number of in vitro diagnostic devices are being used to measure various physiological indicators in the human body, such as blood glucose meters, hemoglobin meters, and electronic pregnancy tests. Traditional in vitro diagnostic devices require one or more physical buttons (such as the setting button S and the memory button M) to perform operations such as time adjustment and querying measurement history. However, accidental presses of physical buttons can lead to data errors or mode switching. Therefore, it is necessary to read the instruction manual carefully before use. These devices are not suitable for all users, especially the elderly or those with operational difficulties. Dust or bacteria may accumulate in the gaps between the buttons, affecting the cleanliness of the device.
[0003] However, if the button is disabled, users cannot view the most recent measurement results. Manual recording is prone to errors; a history query function can automatically save measurement history, reducing human error. Furthermore, most in-vitro diagnostic devices are powered by disposable batteries. Considering power consumption requirements, the instrument may enter sleep mode a few minutes after measurement. If the person is not near the device after the measurement, the result may be missed, requiring repeated measurements and increasing testing costs. Currently, there are in-vitro diagnostic devices on the market with Bluetooth, USB, and NFC capabilities that include historical data reading. However, these features increase the design cost of the device, and during communication, data may be intercepted by others, leading to a risk of privacy breaches.
[0004] Removing the buttons results in a smoother surface for the blood glucose meter, facilitating daily disinfection and maintenance, and meeting the hygiene requirements for medical devices. Removing the buttons also allows for further reduction in size, making the device lighter and more portable, improving portability and satisfying users' dual needs for style and practicality. However, most in-vitro diagnostic devices on the market currently have a historical data query function. This function relies on one or more buttons on the device to access the measurement history query interface. Removing the buttons means that these in-vitro diagnostic devices that rely on buttons for historical data querying no longer have this function.
[0005] Therefore, it is very important to design an in vitro diagnostic device that can query measurement history records without increasing the cost of the device, while eliminating the need for buttons. Utility Model Content
[0006] This invention aims to overcome the problems in the prior art where the historical record query function of existing in vitro diagnostic devices relies on the device's built-in buttons, leading to the risk of accidental touches, complex operation, unsuitability for the elderly, and impact on device cleanliness. It provides an in vitro diagnostic device for querying measurement historical records that simplifies operation, reduces the risk of accidental touches, improves hygiene, and reduces design costs.
[0007] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:
[0008] An in vitro diagnostic device for querying measurement history includes a device housing; a circuit board is provided inside the device housing; a power supply module, a display module, and a slot are provided on the circuit board; the slot is used to trigger the entry into the history query mode by inserting or removing a plug.
[0009] Preferably, the circuit board includes a measurement circuit, a display circuit, a power supply circuit, a main control circuit, and a power-on circuit; the measurement circuit, display circuit, power supply circuit, and power-on circuit are all electrically connected to the main control circuit; the power-on circuit is used to identify whether the plug-in object is inserted in place and whether the plug-in object is pulled out.
[0010] Preferably, the slot is provided with a spring, through which the plug-in electrode is connected to the power-on circuit and the measurement circuit on the circuit board.
[0011] Preferably, the power-on circuit is a slot electrode power-on circuit, used to detect whether the spring on the slot is connected or disconnected; when an object is inserted, the object is connected to the spring, and the level of the status detection pin of the power-on circuit goes low; when the object is pulled out, the object is disconnected from the spring, and the level of the status detection pin of the power-on circuit goes high.
[0012] Preferably, the slot is a limiting structure used to fix the position of the inserted or removed object or to limit the stroke of the inserted or removed object.
[0013] Preferably, the power-on circuit is a limit switch; when an object is inserted, the limit switch is turned on, and when the object is removed, the limit switch is turned off.
[0014] Preferably, the power-on circuit is a magnetic switch, and the corresponding plug-in device is provided with a magnetic element; when the plug-in device is inserted, the magnetic switch outputs a low level, and when the plug-in device is pulled out, the magnetic switch outputs a high level.
[0015] Preferably, the power-on circuit is a photodetector circuit, including a photodiode; when an object is inserted, the light received by the photodiode becomes stronger and the detected voltage level increases; when the object is removed, the light received by the photodiode becomes weaker and the detected voltage level decreases.
[0016] Preferably, the display module includes a display screen or indicator lights.
[0017] Preferably, the insert or remover includes a test strip, a simulation strip, or a quality control strip.
[0018] Compared with the prior art, the advantages of this utility model are: (1) This utility model solution does not require additional buttons. Users can enter the query mode by inserting / removing the test strip, which is familiar to them, thus reducing the learning cost; (2) This utility model uses a circuit for reusing test strip detection (such as a switch to detect whether the test strip is inserted), which does not require additional hardware and reduces equipment costs; it is especially suitable for home or primary healthcare scenarios (such as rural clinics and community service centers), where users do not need to memorize complex operations, thus improving ease of use; (3) This utility model can be operated without separate buttons, which reduces the risk of user operation errors while meeting the user's measurement needs; since there are no buttons, the size of the device can also be designed to be smaller, which greatly reduces the user's usage cost.

[0033] To more clearly illustrate the embodiments of this utility model, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.
[0034] Example:
[0035] like Figure 1 and Figure 2 As shown, this utility model provides an in vitro diagnostic device for querying measurement history records, including a device housing 1; a circuit board 2 is provided inside the device housing; the circuit board is provided with a battery 3 (power supply module), a display screen 4 (display module), and a slot 5; the slot is used to trigger the entry into the history record query mode by inserting or removing an insertable device. This utility model device does not have a physical button for querying history records; history record queries are no longer performed manually by pressing a function button. This utility model device enters working mode after inserting a test strip 6 (insertable device), and automatically enters sleep mode immediately after removing the test strip or after measurement completion, or after the display is maintained for a certain period of time. The device can store or record the most recent one or more measurement history records.
[0036] The insertion and removal components include test strips, simulation strips, control strips, or other components that simulate the insertion and removal process of test strips. The display module and display method include, but are not limited to, an LCD screen; they can also be indicator lights, prompt symbols, voice announcements, etc.
[0037] like Figure 3 As shown, the circuit board includes a measurement circuit, a display circuit, a power supply circuit, a main control circuit, and a power-on circuit; the measurement circuit, display circuit, power supply circuit, and power-on circuit are all electrically connected to the main control circuit; the power-on circuit is used to identify whether the plugged-in object is inserted in place and whether the plugged-in object is pulled out.
[0038] The circuit composition diagrams of the measurement circuit, power supply circuit, display circuit, and main control circuit of this utility model are shown below. Figures 10 to 13 As shown.
[0039] Furthermore, the slot can take many forms. It can be a structural component with springs, through which the test strip electrodes are connected to the power-on circuit and measurement circuit on the circuit board. The slot can also be just a structural component, which serves to fix the position of the test strip or limit the travel of the test strip, and has no electrical connection with the circuit board.
[0040] Furthermore, the power-on circuit can detect whether the test strip is inserted correctly and whether it has been pulled out.
[0041] The power-on circuit can be a limit switch, such as... Figure 4 As shown, inserting the test strip activates the limit switch, and removing the test strip deactivates the limit switch; the power-on circuit can also be a slot electrode power-on circuit, such as... Figure 5 As shown, this is used to detect whether the spring on the slot is connected or disconnected; when the test strip is inserted, the test strip and the spring are connected, and the level of the status detection pin of the power-on circuit goes low; when the test strip is pulled out, the test strip and the spring are disconnected, and the level of the status detection pin of the power-on circuit goes high. The power-on circuit can also be a magnetic switch, such as... Figure 6 As shown, the test strip structure contains magnetic components. Inserting or removing the test strip causes a change in the magnetic switch's voltage level; for example, the magnetic switch outputs a low level when inserted and a high level when removed. The power-on circuit can also be a photodetector circuit, such as... Figure 7 As shown, the state of the test strip is determined by detecting the change in light intensity received by the photodiode D8 when the test strip is inserted or removed. For example, when the test strip is inserted, the light received by the photodiode becomes stronger, and the detected level increases. When the test strip is removed, the light received by the photodiode becomes weaker, and the detected level decreases.
[0042] The working process of this utility model is as follows:
[0043] like Figure 8 As shown, in working mode 1: In sleep mode, when the test strip is inserted into the test strip slot, the device's hardware power-on circuit outputs a level change. The main control circuit detects this level change, defining it as state 1, test strip insertion. The main control circuit then identifies whether there are any measurement history records. If so, it defines state 2, displaying the most recent or multiple measurement history records, such as... Figure 2 As shown, the display shows a fixed holding time; once the historical record is complete, it is defined as state three, and the system proceeds to the test interface; if there is no historical record, it is defined as state three, and the system directly proceeds to the test interface. If the measurement is complete, it is defined as state four, where the measurement result is displayed, and the system waits for the test strip to be removed or displays a fixed holding time. Once the measurement result display ends, it is defined as state six, where the system enters sleep mode, waiting to be awakened by the next insertion of the test strip.
[0044] Table 1 shows the definition of each operating state of the equipment:
[0045] Table 1 Definition of Equipment Operating States
[0046] State 1 Insert test strip, power on and perform initial self-test. State 2 Displays the most recent or multiple measurement history records. State 3 Enter the test interface State 4 Measurement completed, measurement results displayed. State 5 Test strip removed from test interface mode State 6 Enter hibernation mode
[0047] like Figure 9 As shown, in working mode 1: In sleep mode, when the test strip is inserted into the test strip slot, the device outputs a change in level from the hardware power-on circuit. The main control circuit detects this change in level, defining it as state 1, test strip insertion; the main control circuit identifies the current sample application status. If no sample has been applied, it is defined as state 3, entering the test interface; the main control circuit detects a change in level from the hardware power-on circuit, defining it as state 5, test strip removal; the main control circuit identifies whether there is a measurement history record. If so, it is defined as state 2, displaying the most recent or multiple measurement history records for a fixed time; the display of measurement history results ends, defining it as state 6, entering sleep mode, waiting for the next test strip insertion to wake it up; if there is no history record, it is defined as state 6, directly entering sleep mode, waiting for the next test strip insertion to wake it up;
[0048] Mode 3: Without affecting the lifespan of the test strips, different operational needs can be met based on the frequency and number of times the test strips are inserted and removed. Assuming a certain time interval is set, for example, 3 seconds, if the test strip is inserted and removed once, twice, or three times within 3 seconds, different user operational needs can be defined, as shown in Table 2. Inserting and removing once allows viewing the most recent record, inserting and removing twice allows viewing the last 7 measurement records, displayed sequentially from most recent to oldest, until all 7 records are displayed. This function is equivalent to the function of an independent button and can be extended to other functions such as time setting and mode switching.
[0049] Table 2 Functional Description Table Corresponding to Test Strip Insertion / Removal Numbers
[0050]
[0051] The test strip insertion / removal triggers the history query mode at any point during the test strip measurement process. This can be when the device just wakes up from sleep mode, when waiting for sample addition after the test strip is inserted, or after the device enters sleep mode after the measurement is completed.
[0052] The above are just examples of entering the history query mode. It can also be time setting mode, unit switching mode, or other function modes that require certain key operations to enter.
[0053] The full function of a button can be simulated by the frequency or number of times the test strip is inserted and removed per unit time. This function can also switch between different modes and set parameters.
[0054] This invention simplifies operation and meets the needs of most users for querying measurement history. While meeting user measurement requirements, it reduces the risk of user errors; and because there are no buttons, the device can be designed to be smaller, significantly reducing user costs.
[0055] The above description is only a detailed explanation of the preferred embodiments and principles of this utility model. For those skilled in the art, there may be changes in the specific implementation methods based on the ideas provided by this utility model, and these changes should also be considered within the protection scope of this utility model.
