The invention provides an artificial-intelligence–based platform for automated analysis of Pap smear slides. The system integrates preprocessing, dual deep learning models (CNN-Transformer and EfficientNet-LSTM), and reporting modules to classify cytological images into diagnostic categories including NILM, ASC-US, LSIL, HSIL, and SCC. The platform includes interpretability outputs, secure data management, and active learning capabilities, enabling scalable, accurate, and transparent cervical-cancer screening across diverse laboratory settings. The platform is suitable for implementation in clinical pathology laboratories, telemedicine networks, and population-level screening programs. It allows rapid, reproducible, and objective evaluation of cytology slides, improving throughput while reducing reliance on manual slide examination. The invention is deployable on local servers, private clouds, or public cloud infrastructures and is adaptable to various cytology specimens. Adoption of this system enhances early detection of precancerous lesions, reduces inter-observer variability, and facilitates integration with laboratory information systems. It also supports continuous learning and adaptation to evolving imaging protocols. The invention provides multiple advantages over existing methods: (1) Dual-model architecture combining CNN-Transformer and EfficientNet- LSTM ensures robust classification across both dense and sparse cellular regions. (2)Preprocessing and adaptive tiling improve feature extraction from variable-quality images. (3)Interpretability modules enhance clinician trust and facilitate regulatory compliance. (4) Active learning allows continuous improvement based on expert feedback. (5) Modular deployment supports both local laboratory and cloud-based operation. (6) Data security features meet international standards for privacy and encryption. (7) High scalability enables screening of large slide volumes without compromising accuracy. The invention provides a clinically relevant, efficient, and technologically advanced solution for automated cervical-cancer screening, applicable in diverse healthcare environments and adaptable to future cytology domains.

The invention discloses a cervix sampler, an operation method thereof and a kit, the sampler comprises a shell, the shell comprises a shell side wall and a closed shell far-end wall, the shell side wall comprises a first notch, and the first notch is arranged close to the shell far-end wall; the sampling brush is configured to be accommodated in the shell, and at least one part of the sampling brush is exposed to the position of the first notch in at least one use state; the shaft comprises a shaft far end and a shaft near end, the shaft far end is connected with the sampling brush, the shaft near end further comprises an operator, and the operator drives the shaft and the sampling brush to rotate in the circumferential direction under the operation of external force, so that the sampling brush makes contact with a target sample near the first notch in the using state, and friction force is generated to obtain biological tissue. The sampler can be conveniently placed at a target position and sample tissue can be conveniently obtained. The collected biological tissues can be cervical cells, and can be used for double detection (PAP / HPV Co-Testing) of cervical smear (PAP) and human papilloma virus (HPV), and can be used for screening cervical cancer.

We disclose an apparatus for vaginal cell collection which can reliably collect a suitable specimen for cytopathological, molecular and other examination or analysis but which does not have the discomfort of a conventional pap smear test. The device comprises an insertion member having a distal, insertion end, a proximal end and a closable interior cavity; a flexible membrane having an outer, cell sampling surface and an inner surface, wherein said membrane is sealingly attached to the distal, insertion end of said insertion member and held within the interior cavity; such that, in use, pressurisation of the interior cavity to at least a first elevated pressure causes the membrane to emit from the distal end of said insertion member to make contact with the vaginal mucosal surface and pressurisation of the interior cavity to a second reduced pressure causes the membrane to invert and return to the interior cavity of said insertion member; the insertion member having an exterior surface comprising an elongate tip portion with a smooth exterior surface which extends from the distal, insertion end at least as far back as a stop portion comprising at least one transversely-protruding lip extending outwardly from the smooth exterior surface of the tip portion thereby to inhibit insertion beyond the stop portion. The insertion member can comprise an inner section at least part of which is a hollow tubular section thus defining the interior cavity, and a separate outer sleeve attachable to the inner section to extend around the inner section rearwardly from the distal, insertion end, and which includes the at least one lip. The outer sleeve can also include the elongate tip portion with a smooth exterior, and can be attachable to the inner section via screw threads provided on an outer surface of the inner section and an inner surface of the outer sleeve.

This invention introduces a program within the fields of radiology and pathology, leveraging artificial intelligence as a user-friendly diagnostic assistant. Programmed primarily in Python, users can easily interact with the system, choosing among four distinct modules: chest X-ray, liver, Pap smear, and bone fracture diagnostics. Upon uploading the relevant image and submitting it, YOLO (you only look once) version. 8 efficiently detects and analyzes the input images. The integration includes prompt engineering after receiving the required information of the patient and doctor, then it establishes a connection with OpenAI APIs for seamless information exchange and present it to the users. Then there is this chance of allowing users to pose additional questions before receiving the diagnosis report in a printable format which is a Microsoft word file. The patent's main purpose is to elevate accuracy levels in medical diagnosis, real-time imaging responses, and accessibility for users without specialized knowledge.
