Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of pregnancy testing pen, especially relates to a semi-quantitative electronic pregnancy testing pen. BACKGROUND

[0002] The traditional detection means of female pregnancy state mainly involves the detection of HCG hormone level in blood and the detection of urine HCG test paper. Blood detection needs to be completed in a medical institution due to its high accuracy, and lacks convenience. Urine test paper detection is popular due to its simple operation, but its result is easily affected by environmental factors and operation errors, and accurate numerical value cannot be provided in time, which makes it difficult for users to make accurate judgments. At present, there are also some electronic pregnancy testing pens on the market. The documents No. CN206177951U "Electronic pregnancy testing pen device" and CN206177949U "Dual-purpose testing pen for pregnancy testing and disease testing" both disclose electronic pregnancy testing pens with display screens, but they can only perform qualitative measurement and cannot perform quantitative detection. UTILITY MODEL CONTENT

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a semi-quantitative electronic pregnancy testing pen which has simple structure and can perform quantitative analysis on the detection result.

[0004] In order to achieve the above purpose, the technical scheme of the utility model is as follows: a semi-quantitative electronic pregnancy testing pen, comprising a pen shell, a pen cap, a pregnancy test paper strip, a controller, a power supply, an interactive device and a light sensing assembly, a sample adding window is arranged at the front end of the pen shell, the pen cap is detachably inserted into the front end of the pen shell and covers the sample adding window, the pregnancy test paper strip is arranged in the pen shell, and the sample adding end of the pregnancy test paper strip extends into the sample adding window, the controller, the power supply and the light sensing assembly are all arranged in the pen shell, the interactive device is arranged on the outer wall of the pen shell, and the light sensing assembly, the interactive device and the power supply are all electrically connected with the controller, the light sensing assembly is used to identify the color depth of C line and T line on the pregnancy test paper strip, and the interactive device is used to output the detection result.

[0005] The above technical scheme has the beneficial effects that the light sensing assembly can qualitatively determine the color depth of C line and T line on the pregnancy test paper strip, so that the controller can convert the light sensing signal into the concentration signal of HCG in urine and output it, which enables the tester to conveniently know the number of weeks of pregnancy.

[0006] The power supply comprises a button cell, a button cell seat and an insulating film. The button cell seat is arranged in the pen shell and electrically connected with the controller. The button cell is installed on the button cell seat. The side wall of the pen shell is provided with a slit aligned with the button cell seat. The insulating film is inserted into the pen shell through the slit and blocks between the button cell and the button cell seat, so as to disconnect the electrical connection between the button cell and the button cell seat, or the insulating film is pulled out to electrically connect the button cell and the button cell seat.

[0007] The beneficial effect of the above technical solution is that the whole electronic pregnancy test pen is powered by the button cell. When the insulating film is not pulled out, the whole electronic pregnancy test pen is not powered. When the insulating film is pulled out, the urine sample should be added to the sample window as soon as possible to avoid the failure of the electronic pregnancy test pen.

[0008] The light sensing assembly comprises an LED lamp bead and a light sensing sensor, both of which are electrically connected with the controller. The LED lamp bead is used to supplement light for the C line and the T line of the pregnancy test strip. The light sensing sensor is used to identify the reflectance value of the C line and the T line on the pregnancy test strip.

[0009] The beneficial effect of the above technical solution is that the LED lamp bead is lit first after the electronic pregnancy test pen is powered on. At this time, the light sensing sensor measures the reflectance of the C line and the T line. Then, after a period of time (during which the sample is added and the C line and the T line start to develop color), the controller controls the LED lamp to light up again to illuminate the C line and the T line. Then, the light sensing sensor measures the reflectance of the C line and the T line again. At this time, the controller calculates the concentration of HCG in the urine sample according to the degree of reflectance attenuation before and after the sample is added.

[0010] The pregnancy test strip is provided with two, and the two pregnancy test strips are parallel and spaced apart in the pen shell.

[0011] The beneficial effect of the above technical solution is that the accuracy of the measurement is higher.

[0012] The LED lamp bead is provided with four, and one LED lamp bead is arranged on the C line and the T line of each of the two pregnancy test strips.

[0013] The beneficial effect of the above technical solution is that the C line and the T line of each of the two pregnancy test strips are directly irradiated by one LED lamp bead, so that the light intensity of each C line and T line is stable and uniform.

[0014] The light sensor is arranged at the middle part between the four LED lamp beads.

[0015] The beneficial effect of the above technical solution is that the light sensor is arranged at the middle part between the four LED lamp beads, so that the distance between the two C lines and the two T lines is consistent, thereby improving the measurement accuracy.

[0016] The technical solution further comprises a PCB support and a PCB board, the PCB support is arranged at the rear upper end of the two test strips, the PCB support is provided with four light transmission holes arranged in a rectangular shape and a light sensing hole arranged at the middle part between the four light transmission holes, the C line and the T line of the two test strips are respectively aligned with one light transmission hole, the LED lamp beads and the light sensor are arranged on the PCB board, the PCB board is arranged on the PCB support, the light sensor is arranged at the light sensing hole, and the four LED lamp beads are arranged at the four light transmission holes.

[0018] The controller is integrated on the PCB board.

[0019] The beneficial effect of the above technical solution is that the degree of integration is high.

[0020] The interactive device is a display screen.

[0021] The beneficial effect of the above technical solution is that the concentration of the measured HCG can be directly displayed on the display screen.

[0040] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will be more clearly described in light of the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0041] Example 1

[0042] like Figures 1-7 As shown, this embodiment provides a semi-quantitative electronic pregnancy test pen, including a pen shell 1, a pen cap 2, a pregnancy test strip 3, a controller 4, a power supply 5, an interactive device 6, and a photosensitive assembly 7. The pen shell 1 has a sample application window 11 at its front end. The pen cap 2 is detachably inserted into the front end of the pen shell 1 and covers the sample application window 11. The pregnancy test strip 3 is disposed within the pen shell 1, and the sample application end of the pregnancy test strip 3 extends into the sample application window 11. The controller 4, the power supply 5, and the photosensitive assembly 7 are all disposed within the pen shell 1. Inside, the interactive device 6 is disposed on the outer wall of the pen shell 1, and the light sensing assembly 7, the interactive device 6, and the power supply 5 are all electrically connected to the controller 4. The light sensing assembly 7 is used to identify the color depth of the C line and T line on the pregnancy test strip 3, and the interactive device 6 is used to output the test result. In this way, the light sensing assembly can qualitatively determine the depth of the color change of the C line and T line on the pregnancy test strip, and the controller can convert the light sensing signal into the concentration signal of HCG in urine and output it, so that the tester can conveniently know the number of weeks of pregnancy.

[0043] See details Figure 1As shown, the semi-quantitative electronic pregnancy test pen provided by the embodiment is a disposable product, so before the electronic pregnancy test pen is used, the cap is inserted into the end of the pen shell provided with the sample adding window (the way of inserting the cap into the pen shell is similar to the way of inserting the cap of the current pen into the pen, so it is not described here), when the cap is inserted into the pen shell, the end of the pregnancy test strip located in the sample adding window can be closed (to avoid invalidation and deterioration due to light or moisture absorption before use), so the pregnancy test strip 3 needs to be stably positioned in the pen shell. In the embodiment, the sample adding window can be a square groove or a square hole, and its volume can be determined according to the sample amount. The side wall of the pregnancy test strip penetrating the sample adding window needs to be waterproof to prevent urine from seeping into the pen shell (urine can only be absorbed by the C line and T line of the pregnancy test strip).

[0044] As Figures 1-5 As shown, the power supply 5 in the above technical solution includes a button cell 51, a button cell seat 52, and an insulating film 53. The button cell seat 52 is arranged in the pen shell 1 and electrically connected with the controller 4. The button cell 51 is installed on the button cell seat 52. The side wall of the pen shell 1 is provided with a slit 12 aligned with the button cell seat 52. The insulating film 53 is inserted into the pen shell 1 through the slit 12 and blocks between the button cell 51 and the button cell seat 52, so as to disconnect the electrical connection between the button cell 51 and the button cell seat 52, or the insulating film 53 is pulled out to electrically connect the button cell 51 and the button cell seat 52. In this way, the entire electronic pregnancy test pen is powered by the button cell. However, when the insulating film is not pulled out, the entire electronic pregnancy test pen is not powered. After the insulating film is pulled out, the urine sample needs to be added into the sample adding window as soon as possible (or the corresponding end of the pen shell is directly inserted into the urine, so that the corresponding end of the pregnancy test strip is immersed in the urine), so as to avoid the invalidation of the electronic pregnancy test pen. The power supply in the embodiment belongs to the prior art, and the power supply of the current lighted fluorescent stick is similar to it. The insulating film of the power supply needs to be pulled out before the first use after being sold.

[0045] As Figures 3-7As shown, the light sensing assembly 7 in the technical scheme comprises LED lamp beads 71 and a light sensing sensor 72, the LED lamp beads 71 and the light sensing sensor 72 are electrically connected with the controller 4, the LED lamp beads 71 are used to supplement light for the C line and the T line of the pregnancy test strip 3, and the light sensing sensor 72 is used to identify the reflection value of the C line and the T line of the pregnancy test strip 3. Thus, after the electronic pregnancy test pen is powered on, the LED lamp beads are first lit, at this time, the light sensing sensor measures the reflectivity of the C line and the T line, then after a period of time (during which the sample is applied and the C line and the T line begin to develop color), the controller controls the LED lamp to be lit again to illuminate the C line and the T line, and then the light sensing sensor measures the reflectivity of the C line and the T line again, at this time, the controller calculates the concentration of HCG in the urine sample according to the attenuation degree of the reflectivity before and after the sample is applied.

[0046] In the embodiment, two LED lamp beads are arranged, and the two LED lamp beads are arranged at the C line and the T line of the pregnancy test strip 3 respectively, and the light sensing sensor is arranged at the middle part between the two LED lamp beads.

[0047] Specifically, as shown, Figures 3-7 In the embodiment, a PCB support 8 and a PCB board 9 are further included, the PCB support 8 is arranged at the upper rear end of the pregnancy test strip 3, and the PCB support 8 has two light transmission holes 81 arranged at intervals and a light sensing hole 82 arranged at the middle part between the two light transmission holes 81, the C line and the T line of the pregnancy test strip 3 are respectively aligned with one of the light transmission holes 81, the LED lamp beads 71 and the light sensing sensor 72 are arranged on the PCB board 9, and the PCB board 9 is arranged on the PCB support 8, the light sensing sensor 72 is arranged at the light sensing hole 82, and the two LED lamp beads 71 are arranged at the two light transmission holes 81 respectively, so that the PCB support and the PCB board can form a black box at the C line and the T line of the pregnancy test strip together, and the LED lamp beads and the light sensing sensor are arranged at the black box, so that the influence of external light on the detection result can be avoided, and the detection accuracy is higher.

[0048] In the technical scheme, the controller 4 is integrated on the PCB board 9, and the degree of integration is high (in the embodiment, the controller can be a micro control chip integrated on the PCB board, and an STM32 series micro control chip can be specifically used, and the cost is low).

[0049] The interaction device 6 is a display screen, so that the concentration of the measured HCG can be directly displayed on the display screen.

[0050] In this embodiment, the two LED lamp beads do not light up at the same time to avoid deviation of the reflected light signal received by the light sensor.

[0051] The use principle of the semi-quantitative electronic pregnancy test pen provided in this embodiment is as follows: after the insulating film of the power supply is pulled out, the entire electronic pregnancy test pen is in a powered-on state, and the controller is pre-set. After being powered on, the controller first controls the LED lamp bead at the T line to light up first, the light sensor collects a signal A1, then the LED lamp bead at the T line is extinguished, the controller controls the LED lamp bead at the C line to light up, the light sensor collects a signal B1, and after a certain time length (which can be set to 7 minutes, at which time the T line and the C line on the pregnancy test strip have completed color change), the controller controls the LED lamp bead at the T line to light up again, the light sensor collects a signal A2, then the LED lamp bead at the T line is extinguished, the controller controls the LED lamp bead at the C line to light up again, the light sensor collects a signal B2, and the controller can convert the concentration information of HCG according to the four values of the signal A1, the signal B1, the signal A2 and the signal B2, and output by the interaction device (since the controller controls the lamp bead to light up twice after a certain time interval, and at this time the C line and the T line on the pregnancy test strip need to have obvious color change, therefore, the electronic pregnancy test pen needs to add the urine sample into the sample adding window within one or two minutes after being powered on, otherwise, it may cause inaccurate pregnancy test result (if the sample is added before being powered on, the C line and the T line may have color change when the two lamp beads light up for the first time, which affects the accuracy of the signal A1 and the signal B1; if the time interval after being powered on exceeds the required time length, the C line and the T line may just start to have slight color change when the two lamp beads light up for the second time, which affects the accuracy of the signal A2 and the signal B2)).

[0052] The interaction device in this embodiment can also be a demonstration lamp (which can emit red light, yellow light or green light, when the detection result indicates that the user is not pregnant, the red light can be lit, when the detection result indicates that the user is pregnant within three weeks, the yellow light can be lit, and when the detection result indicates that the user is pregnant for more than three weeks, the green light can be lit).

[0053] In this embodiment, a through hole is arranged at the side wall of each light transmission hole close to the side of the light sensing hole, and the lower end of the light sensing hole is sealed, while the lower end of each light transmission hole is sealed by the pregnancy test strip, so that the light emitted by each LED lamp bead is vertically irradiated on the pregnancy test strip and reflected to the light sensor 72 through the through hole, so that the detection accuracy of the light sensor is higher (the light shielding effect of the black box is better).
