Abstract
Description
Technical Field
[0001] The present application relates to the field of medical technology, and in particular to a device for determining the results of an allergy prick test. Background Art
[0002] In the allergy prick test, the currently commonly used technical means have significant deficiencies. These deficiencies are mainly reflected in the following aspects: At present, ordinary light sources are generally used to interpret the results of allergy prick tests. Ordinary light sources often cannot provide stable and appropriate lighting conditions, resulting in insufficient or uneven light during the interpretation process. It is difficult for doctors or nurses to accurately observe the wheal papules generated at the puncture site, thus affecting the accuracy of the results; the diameter of the papule is usually measured by naked eye observation and ruler measurement. The ruler is easy to contact the patient's skin and puncture point during use. If it is not discovered and disinfected in time, it may cause cross infection when used again on the next patient, increasing medical risks; during the manual reading calculation process, due to human arithmetic errors, the result reading may be inaccurate, affecting the reliability of diagnosis; due to individual differences, the epidermal area and positive control papule diameter of different patients may be different. However, the existing technology usually uses a unified data standard to determine the positive value, which ignores the individual differences between patients and may lead to inaccurate interpretation results.
[0003] In summary, the existing technology has many deficiencies in the interpretation of allergy prick test results, including insufficient light source, inaccurate measurement and interpretation methods, and lack of flexible adjustment mechanism for individual differences. These problems seriously affect the accuracy and reliability of allergy prick test results.
[0004] Therefore, it is necessary to develop a new allergy prick test result determination device to solve these problems. Summary of the invention
[0005] The present application provides an allergy prick test result determination device, which can assist doctors in flexibly adjusting the light source according to individual differences of patients when determining the allergy prick test results, thereby improving the accuracy of doctors' determination of allergy prick test results.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0029] In one embodiment of the present application, a device for determining the result of an allergy prick test is provided. Figure 1 As shown, including:
[0030] The projection module 100 includes at least one light source lamp body, which is used to project apertures of different diameters;
[0031] The aperture adjustment module 200 includes a control unit 201, a ratio setting unit 202 and a ratio adjustment unit 203, wherein the control unit is used to adjust the aperture diameter projected by the light source lamp body according to the input diameter; the ratio setting unit is used to set the relative ratio between the aperture diameters projected by each of the light source lamp bodies; and the ratio adjustment unit is used to adjust the aperture diameters projected by the other light source lamp bodies according to the relative ratio when receiving a diameter adjustment signal of one of the light source lamp bodies.
[0032] The reading module 300 includes a camera and a numerical reading unit. The camera is used to photograph the skin mound and its corresponding aperture to obtain a picture to be judged; the numerical reading unit is used to identify the picture to be judged, calculate the ratio of the aperture diameter projected by the light source lamp body to the diameter of the skin mound, and automatically judge and record the allergy prick test results.
[0033] In a specific implementation, the light source lamp body is an LED lamp or other light-emitting device that can project a circular aperture of a specific diameter. The projection adjuster includes a projector focal length adjuster, which can adjust the aperture diameter according to the given dot diameter. Among the light source lamp bodies, at least one light source lamp body allows the user to manually adjust the aperture through the control module. After the user manually adjusts the aperture, the ratio adjustment unit receives the diameter adjustment signal of the light source lamp body and adjusts the aperture diameters projected by other light source lamp bodies according to a preset relative ratio.
[0034] The numerical reading unit identifies the edges of the skin bump and the aperture through an image recognition algorithm, and calculates the diameters of the two, thereby obtaining the ratio of the aperture diameter projected by the light source lamp body to the diameter of the skin bump, automatically interprets this ratio according to a preset interpretation standard, and summarizes all the interpretation results into an allergy prick test result, which is then stored and recorded.
[0035] Furthermore, the light source lamp body includes at least five lamp bodies, which are respectively used to project a control aperture, a negative aperture, a positive first aperture, a positive second aperture and a positive third aperture, and the ratio setting unit sets the relative ratio so that the diameter of the negative aperture is equal to 25% of the diameter of the control aperture, the diameter of the positive first aperture is equal to 50% of the diameter of the control aperture, the diameter of the positive second aperture is equal to 100% of the diameter of the control aperture, and the diameter of the positive third aperture is equal to 200% of the diameter of the control aperture.
[0036] Furthermore, the control unit is further configured to adjust the diameters of the apertures projected by the other light source lamp bodies based on the relative ratio according to the preset diameter of the control aperture.
[0037] In this embodiment, the projection aperture adjusted by the projection regulator according to the diameter of the positive control skin mound is used to compare the diameter of the skin mound, which can assist doctors to make more accurate comparison references, avoid artificial arithmetic errors in the manual reading calculation process, and improve the accuracy of the interpretation. Specifically, the reader can set the diameter of the control aperture according to the diameter of the positive control skin mound of different patients, and project the apertures of different diameters through the relative proportion preset by the aperture adjustment module and the proportion adjustment module, and then project the apertures of different diameters onto the patient's skin mound to obtain a comparison chart of the skin mound diameter and the aperture diameter, and then use the image recognition algorithm to interpret the skin mound diameter according to the preset interpretation standard to obtain the interpretation results such as negative, positive +, positive ++, etc., to achieve personalized interpretation and improve the objectivity and accuracy of the interpretation. The device can also avoid the situation that the traditional ruler may contact the patient's skin and puncture point during measurement, reduce the risk of cross infection, and improve the safety of medical operations. The image recognition algorithm automatically captures and identifies the diameter of the measurement spot, and automatically calculates the results and enters them into the medical record, which simplifies the operation process, saves time, and facilitates data collection and follow-up.
[0038] In some embodiments, it also includes:

[0043] The fixing module is used to fix the light source lamp body of the projection module.
[0044] Furthermore, the light source lamp body is connected to the fixing module via a retractable or bendable lamp post.
[0045] In a specific implementation, the fixing module may be a base, to which a plurality of retractable or bendable lamp posts are connected, and to which the light source body is connected.
[0046] In this embodiment, the light source body is fixed by the fixing module, which avoids the inconvenience of the handheld light source that must be used in the traditional interpretation, such as shaking, and is conducive to the interpretation of the acupuncture results. Multiple retractable or bendable lamp posts can flexibly move each light source body when there is a need to move the light source.
[0047] In some embodiments, it also includes:
[0048] The report generating module generates a reading report in a preset format according to the allergy prick test result of the reading module.

[0053] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
