[0019] The skin prick test system according to an embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, the skin prick test system according to the embodiment of the present application includes: a prick positioning unit, a liquid prick unit, an image acquisition unit and a central processing unit.

[0021] Specifically, the pricking positioning unit is suitable for generating pricking marking points on the skin, the liquid pricking unit is suitable for applying liquid and pricking the locations of the pricking marking points, the image acquisition unit is suitable for acquiring skin images and pricking marking point images, and sending image data representing the skin images and pricking marking point images, and the central processing unit is suitable for receiving and analyzing the image data to generate test results.

[0022] In other words, if Figure 1 As shown, the skin prick test system according to the embodiment of the present application mainly includes a prick positioning unit, a liquid prick unit, an image acquisition unit and a central processing unit, wherein the prick positioning unit can generate a prick mark point on the skin, and the prick mark point can provide an accurate prick position on the skin without manual measurement and marking, and the liquid prick unit can dispense liquid and prick the position of the prick mark point without the need for operation by medical staff, thus saving time and effort; the image acquisition unit is mainly composed of a camera, and after a certain period of time of prick, the image acquisition unit can acquire skin images (the skin images include the wheal images generated after skin prick), as well as the prick mark. The prick positioning unit presents the prick mark point image on the skin, and the image acquisition unit can be connected to the central processing unit by wired communication or wireless communication (for example, Bluetooth, wireless network, etc.), so that the image acquisition unit can send image data representing the skin image and the prick mark point image to the central processing unit; the central processing unit can be the CPU of a computer (that is, an industrial computer), the central processing unit can receive the image data sent by the acquisition unit, and the central processing unit can analyze and process the received image data. After the analysis and processing by the central processing unit, the test result can be directly obtained without manual measurement, calculation and judgment of the result.

[0023] Therefore, according to the skin prick test system of the embodiment of the present application, the prick positioning unit can automatically generate prick mark points on the skin without manual measurement and marking, and the liquid injection and pricking unit can automatically perform liquid injection and pricking operations at the pricking mark points, which can effectively improve the test efficiency, and the image acquisition unit can quickly acquire skin images and injection mark point images, which can reduce the time and errors of manual operation and improve the efficiency and accuracy of the test. At the same time, the central processing unit can automatically analyze the image data and generate test results, which can further improve the efficiency and accuracy of the test.

[0024] In some specific embodiments of the present application, the prick mark point is the center point of the wheal, and the central processing unit is suitable for automatically calculating the wheal size through the image shape and center point recognition algorithm, and generating the test result according to the calculation result.

[0025] That is to say, the skin prick test system can use the prick mark point as the center point of the wheal, and the central processing unit can automatically calculate the size of the wheal by implementing the image shape and center point recognition algorithm system through a software program.

[0026] In one example, the size of the wheal can be characterized by the diameter of the wheal, which is calculated using the average diameter, and the average diameter S=(d+D) / 2, where d is the size of the wheal passing through the center of the wheal in the x direction (the x direction ensures that d is the maximum size of the wheal), and D is the size of the wheal passing through the center of the wheal in the y direction, where the y direction is perpendicular to the x direction; when analyzing and processing image data, it is determined that the average diameter of the wheal falls within a preset range, and the result corresponding to the preset range is the test result.

[0027] In another example, the size of the wheal can be represented by the maximum diameter of the wheal. When analyzing and processing the image data, it is determined whether the maximum diameter of the wheal falls within a preset range, and the result corresponding to the preset range is the test result.

[0028] In this embodiment, the central processing unit can automatically calculate the wheal size through the image shape and center point recognition algorithm, which solves the time-consuming and labor-intensive problems existing in the traditional manual measurement method, effectively improves the convenience of the test operation and the accuracy of the results, and uses the prick mark point as the center point of the wheal to simplify the system algorithm, which is conducive to the central processing unit to quickly calculate the wheal size.

[0029] In another example, the image acquisition unit can also collect the area of ​​the pricking fluid. The size of the wheal can be characterized by the maximum area of ​​the wheal. When analyzing and processing the image data, the ratio of the area of ​​the wheal to the area of ​​the pricking fluid is calculated, and then the preset range within which the ratio falls is determined. The result corresponding to the preset range is the test result.

[0030] In this example, the central processing unit can quickly obtain the test results based on the ratio of the area of ​​the wheal to the area of ​​the pricking fluid, effectively improving the efficiency and accuracy of the test.

[0031] In some optional examples of the present application, the central processing unit can automatically analyze and process the diameter, circumference, area, color of the pricked wheal, as well as the ranking of the diameters and areas of multiple wheals through an image shape and center point recognition algorithm.

[0032] According to one embodiment of the present application, the prick positioning unit includes: a first laser emission module and a second laser emission module, the first laser emission module is suitable for generating a first prick marking point on the skin, the second laser emission module and the first laser emission module are distributed along a first direction, and the second laser emission module is suitable for generating a second prick marking point on the skin.

[0033] Specifically, the pricking positioning unit mainly includes a plurality of laser emitting modules distributed along a first direction, and the laser emitting modules can emit red light beams toward the skin, thereby forming red light spots on the skin, i.e., pricking marking points. In this embodiment, the number of laser emitting modules is two, i.e., the pricking positioning unit includes a first laser emitting module and a second laser emitting module, and the first laser emitting module and the second laser emitting module are spaced apart and distributed along a first direction (e.g., the width direction of the arm), so that the first laser emitting module can generate a first pricking marking point on a first side (e.g., the inner side) of the skin, and the second laser emitting module can generate a second pricking marking point on a second side (e.g., the outer side) of the skin.

[0034] In this embodiment, the first laser emission module and the second laser emission module can generate prick marking points on both the inner and outer sides of the skin on the palm side of the patient's forearm, which is conducive to conducting a control test.

[0035] In some specific embodiments of the present application, the prick positioning unit also includes: a first drive module, a second drive module and a control module, the first drive module is connected to the first laser emission module, the first drive module is suitable for driving the first laser emission unit to move along the first direction, the second drive module is connected to the second laser emission module, the second drive module is suitable for driving the second laser emission unit to move along the first direction, the control module is electrically connected to the first drive module and the second drive module, and the control module is suitable for receiving control instructions from the central processing unit to control the operation of the first drive module and the second drive module.

[0036] That is to say, in the first direction, the distance between the first laser emitting module and the second laser emitting module is adjustable, that is, the first laser emitting module is movable along the first direction, and the second laser emitting module is also movable along the first direction, so that the distance between the first laser emitting module and the second laser emitting module is adjustable, and different distances can be adjusted according to the physical characteristics and test requirements of different patients, which can ensure that the distance between the two meets the acupuncture requirements, and the positions of the first laser emitting module and the second laser emitting module in the first direction can be adjusted, so as to facilitate the adjustment of the positions of the first laser emitting module and the second laser emitting module according to actual needs.

[0037] Furthermore, the pricking positioning unit also includes a driving module for driving the laser emitting module to move along the first direction. The number of the driving modules is the same as that of the laser emitting modules. The driving modules are for example, but not limited to, a screw structure, a telescopic cylinder, etc. In this embodiment, the pricking positioning unit includes a first driving module and a second driving module. The first driving module and the second driving module are both electrically connected to the control module. The control module is communicatively connected to the central processing unit. The output end of the first driving module is fixedly connected to the first laser emitting module. The output end of the second driving module is fixedly connected to the second laser emitting module. Therefore, the central processing unit can send control instructions to the control module, so that the control module can control the operation of the first driving module and the second driving module, which is beneficial to control the first laser emitting module and the second laser emitting module to move along the first direction, and facilitates adjusting the positions of the first laser emitting module and the second laser emitting module according to actual needs.

[0038] According to one embodiment of the present application, the first laser emission module is suitable for generating a plurality of first pricking marking points distributed along a second direction on the skin; and / or, the second laser emission module is suitable for generating a plurality of second pricking marking points distributed along a second direction on the skin.

[0039] Specifically, the first laser emitting module includes a plurality of first emitting parts spaced apart and distributed along a second direction (for example, the length direction of the arm, i.e., the direction from the proximal end to the distal end), and each first emitting part can generate a first pricking mark point on the patient's skin; the second laser emitting module includes a plurality of second emitting parts spaced apart and distributed along the second direction, and each second emitting part can generate a second pricking mark point on the patient's skin.

[0040] Therefore, the first transmitting module can generate multiple first prick marking points on the skin, and the second transmitting module can generate multiple second prick marking points on the skin, so that the skin prick test system can mark from the proximal end to the distal end and then from the distal end to the proximal end on either side of the inner or outer sides of the palmar forearm skin of the patient during the skin prick test for allergic rhinitis. Multiple test points can be marked at one time, which is conducive to conducting different allergy control tests at the same time, improving the efficiency of the test and the richness of the data, and is suitable for more complex research and diagnostic needs.

[0041] In some specific embodiments of the present application, the image acquisition unit includes a binocular camera, which is suitable for acquiring skin images and prick mark point images at different viewing angles.

[0042] That is to say, the image acquisition unit is mainly composed of a binocular camera, which includes a first camera module and a second camera module distributed along a second direction. The first camera module and the second camera module can be used to capture skin images and puncture mark point images at different viewing angles. This multi-angle acquisition mechanism enhances the comprehensiveness and accuracy of image data, provides a more reliable basis for subsequent image analysis and result judgment, and is conducive to ensuring the accuracy of the test results.

[0043] In some optional examples of the present application, the image acquisition unit mainly includes a binocular camera, which can capture skin images in multiple directions, so that the image acquisition unit can capture three-dimensional skin images and prick marker point images on the three-dimensional skin images, and the image data representing the three-dimensional skin images and the prick marker point images can be analyzed and processed by the central processing unit.

[0044] That is to say, the skin image acquired by the image acquisition unit is a three-dimensional skin image, which is more conducive to ensuring the authenticity of the shape and size of the wheal than the two-dimensional skin image, and can further ensure the accuracy of the prick test result.

[0045] According to one embodiment of the present application, the skin prick test system also includes: a marking member, which is suitable for being attached to the skin to determine the prick area on the skin and provide segmentation information of the skin image to the image acquisition unit so that the central processing unit can process the image data according to the segmentation information.

[0046] Specifically, the skin prick test system may also include a marking piece, which may be a sticker structure, and the marking piece may be provided with one or more through holes. When in use, the marking piece may be pasted on the patient's skin, so that the pricking area to be pricked may be framed through the through holes of the marking piece, so that the image acquisition unit may identify the approximate range of the required pricking, and the central processing unit may quickly adjust the position of the laser emission module according to the pricking area, so as to facilitate adjusting the laser emission module to the correct position, which may improve the test efficiency; and the position of the marking piece without a through hole may provide the central processing unit with the segmentation information of the skin image, and the central processing unit may segment the three-dimensional skin image according to the segmentation information, which is beneficial for the central processing unit to process the image data, and may further improve the test efficiency.

[0047] In some specific embodiments of the present application, the skin prick test system further includes: a disinfection and cleaning unit, which is adapted to receive control instructions from the central processing unit and disinfect and clean the skin at the location of the prick mark point according to the control instructions.

The disinfection and cleaning unit can receive control instructions from the central processing unit and spray disinfectant on the puncture area according to the control instructions to disinfect and clean the skin at the location of the puncture mark.

[0049] Therefore, the disinfection and cleaning unit can automatically perform disinfection and cleaning work, reducing the disinfection and cleaning process for medical staff and improving test efficiency.

[0050] Furthermore, the disinfection and cleaning unit mainly includes a disinfection pump and a nozzle, etc. The disinfection pump can supply liquid to the nozzle, and the nozzle can spray the disinfectant liquid to the skin of the pricking area, so as to disinfect the skin of the pricking area. The nozzle of the disinfection and cleaning unit can be provided with a separate driving structure to drive it to move to a position corresponding to the pricking area, or it can be integrated on the first driving module or the second driving module to move together with the laser emission module, so as to simplify the structure of the skin pricking test system and improve the integration of the skin pricking test system.

[0051] According to one embodiment of the present application, the skin prick test system further includes: an information input unit, the information input unit is electrically connected to the central processing unit, and the information input unit is suitable for inputting at least one of patient information, test parameters and control instructions.

In the present embodiment, the information input unit is mainly composed of a keyboard and a mouse. By inputting patient information, test parameters (for example, test parameters such as allergen type, prick dose, prick depth, prick interval, test time, and reference parameters such as wheal diameter, circumference, area, and color change required for image analysis) and control instructions (for example, instructions for moving prick marker points, image acquisition instructions, etc.), etc., the system operation process can be effectively simplified, and the system usability and operational flexibility can be improved.

[0053] In some specific embodiments of the present application, the skin prick test system also includes: a network interface unit, the network interface unit is electrically connected to the central processing unit, the network interface unit can receive case information from the hospital information system, and the network interface unit can upload the test results to the hospital information system to update the case information.

[0054] That is to say, the skin prick test system is also provided with a network structure unit, and the network interface unit is electrically connected to the central processing unit. The skin prick test system can realize data transmission with the hospital information system through the network interface unit, that is, the case information from the hospital information system can be received through the network interface unit, and the skin prick test system can upload the test results to the hospital information system through the network interface unit, so as to achieve the purpose of updating the patient's case information, which is facilitating the subsequent retrieval of required information.

[0056] Specifically, the skin prick test system is also provided with an information storage unit, which may be a hard disk of a computer. The information storage unit is electrically connected to the central processing unit and the image acquisition unit. The information storage unit may be used to store image data and test results, which is convenient for users to view image data and test results. The information storage unit is also installed with the software program required for the skin prick test system, so that the central processing unit can access and run the software program when the system is running.

[0057] In some specific embodiments of the present application, the skin prick test system also includes: an information display unit, which is electrically connected to the central processing unit and is suitable for displaying the test results; and / or, an information printing unit, which is electrically connected to the central processing unit and is suitable for printing the test results.

[0058] That is to say, the skin prick test system is provided with an information display unit, which is, for example, but not limited to, a display.

The information printing unit is electrically connected to the central processing unit, and the central processing unit can control the information printing unit to print out the test results, so as to facilitate the storage and viewing of the test results.

[0059] Thus, when the skin prick test system is used, the patient's arm is first fixed, and the marking piece is attached to the skin on the arm where prick is required, and then the control instruction for adjusting the first laser emitting module and the second laser emitting module is input through the information input unit. After receiving the input control instruction, the central processing unit sends a control instruction to the control module, and the control module controls the first laser emitting module and the second laser emitting module to move to corresponding positions. The first laser emitting module and the second laser emitting module generate a first prick mark point and a second prick mark point on the patient's skin. At this time, the image acquisition unit acquires the skin image and the prick mark point image, and sends a representation to the central processing unit. The central processing unit sends a disinfection control instruction to the disinfection and cleaning unit according to the received image data. After receiving the disinfection control instruction, the disinfection and cleaning unit disinfects the skin in the puncture area. Then the central processing unit sends a liquid puncture control instruction to the liquid puncture unit. After receiving the liquid puncture control instruction, the liquid puncture unit drips puncture liquid and punctures the positions of the first puncture mark point and the second puncture mark point. After puncturing for a set time, the image acquisition unit automatically or by the operator controls to acquire the skin image and the puncture mark point image, and then automatically calculates the wheal size through the software program, thereby realizing automatic judgment.

The positions of the laser emission module and the second laser emission module make the distance between the puncture mark points meet the puncture requirements; then the central processing unit controls the disinfection and cleaning unit to disinfect the skin in the puncture area, and controls the liquid puncture unit to drip the puncture liquid at the puncture mark point position and puncture at the puncture mark point position; after a certain period of puncture (for example, 15 to 20 minutes), the image acquisition unit collects the skin image and the puncture mark point image presented on the skin by the puncture positioning unit. The operator sets the diameter, circumference, area, color change and other parameters for the required image according to the analysis needs through the image information collected by the image acquisition unit, and analyzes and judges by setting the obtained image parameters. After the operator makes a judgment based on the analyzed data, the final result is printed through the information printing unit, and the relevant information is uploaded to the hospital management platform through the network interface.
