Description

Technical Field

[0001] The present invention relates to the technical field of AIDS detection, and in particular to a self-service AIDS detection device. Background Art

[0002] Early detection of HIV is crucial for timely treatment and control of disease transmission. In recent years, self-service HIV testing devices have attracted increasing attention due to their convenience and privacy protection. However, existing self-service HIV testing devices, especially personal HIV test kits, still have many shortcomings in practical applications, which limit their effectiveness in a wide range of populations.

[0003] Existing personal HIV test kits are cumbersome to use. Users usually need to collect blood or saliva samples themselves and go through a series of complicated steps to complete the test. This process not only involves multiple operating steps, but also requires users to have certain operating skills and patience. For first-time users, this complexity may lead to improper operation, thus affecting the accuracy of the test results. In addition, the blood collection process itself may make some users feel uncomfortable or frightened, reducing their willingness to conduct self-testing.

[0004] Existing personal HIV test kits lack an integrated design. This means that users need to purchase a variety of different components, such as blood collection needles, test strips, disinfectants, etc., and use these components separately at different stages. This decentralized component design not only increases the cost for users, but may also cause the loss or damage of certain components, affecting the smooth progress of the test. In addition, the decentralized components also increase the inconvenience of users in storage and carrying, especially when traveling or going out, users may not be able to conveniently carry all the necessary testing tools. This inconvenience further limits the scope of application of self-service HIV testing.

[0005] Existing personal HIV test strip kits also have obvious limitations in terms of result interpretation. Many test strip test results require users to judge based on color changes or other visual indications, which requires users to have a certain degree of interpretation ability. However, the interpretation ability and experience vary greatly between different users, which can easily lead to misjudgment or misunderstanding. Even those devices that provide digital display results may increase user distress due to small or unclear display screens. In addition, some users may find it difficult to objectively judge the results due to nervousness or anxiety, which affects the accuracy of the test. This uncertainty not only increases the psychological burden on users, but may also lead to wrong decisions.

[0006] Existing personal HIV test kits also have deficiencies in privacy protection. Although self-service testing provides higher privacy protection, users still need to be careful to handle the test results during use to avoid being seen by others. Especially in a home environment, users may worry that the test results will be discovered by family members or roommates, which will cause unnecessary psychological pressure. Therefore, a more private and safe test device design is crucial to improve user acceptance and satisfaction.

[0007] Existing personal HIV test kits also need to be improved in terms of user experience. Many devices lack user-friendly interface design and detailed instructions for use, making it difficult for first-time users to quickly get started. In addition, the operating steps of some devices are cumbersome, requiring users to read the instructions multiple times to complete the test correctly. This complexity not only increases user frustration, but may also reduce the frequency of user use, thereby affecting the early detection and treatment of the disease. Poor user experience will also lead to a decrease in user trust in the product, further hindering the popularization of self-service HIV testing.

[0008] Therefore, how to provide a self-service AIDS detection device is a problem that those skilled in the art need to solve urgently. Summary of the invention
