A training and/or evaluating device is provided particularly useful in performing laparoscopic procedures, radiological procedures, and precise surgeries that simulates the structure and dynamic motion of the corresponding anatomical structure on which the procedure takes place. The device includes an outer housing, which may be designed to mimic the body wall, in which one or more organs are located. Motion of the organ(s), as a result of respiration, pulmonary action, circulation, digestion and other factors present in a live body, is simulated in the device so as to provide accurate dynamic motion of the organs during a procedure.

Conductive elastomeric circuits are used in various simulated physiological structures such as tissues and organs, enabling feedback to be provided indicating whether a simulated task is being performed correctly. For example, a surgical trainer has a simulated human tissue structure made of an elastomeric composition, at least one reinforcing layer of a fibrous material, and at least one flexible electrical circuit. The surgical trainer preferably includes multiple areas for practicing surgical skills, each with evaluation circuits for providing feedback regarding that skill. Conductive elastomers are also incorporated into other types of medical training simulators, to similarly provide feedback. In another embodiment, a simulated organ has a conductive elastomeric circuit in the periphery of the simulated organ, enabling feedback to be provided to evaluate whether a person is properly manipulating the organ in response to a manual applied pressure.

Multiple modality contrast can be used to produce images that can be combined and rendered to produce images similar to those produced with wavelength absorbing stains viewed under transmitted white light illumination. Images obtained with other complementary contrast modalities can be presented using engineered color schemes based on classical contrast methods used to reveal the same anatomical structures and histochemistry, thereby providing relevance to medical training and experience. Dark-field contrast images derived from refractive index and fluorescent DAPI counterstain images are combined to produce images similar to those obtained with conventional H&E staining for pathology interpretation. Such multi-modal image data can be streamed for live navigation of histological samples, and can be combined with molecular localizations of genetic DNA probes (FISH), sites of mRNA expression (mRNA-ISH), and immunohistochemical (IHC) probes localized on the same tissue sections, used to evaluate and map tissue sections prepared for imaging mass spectrometry.

The invention provides a hospital decision-making aiding method based on symptom similarity analysis, belonging to the field of information analysis and decision-making aid. The method comprises the following steps: establishing a disease database, a symptom database, a department database and a correlating relationship; establishing a patient model for symptoms input by users, and calculating the similarity between the patient model and a disease model; and searching one department with corresponding suspected diseases in the department model to serve as hospital reference. The method has the advantages that an error interrupted result is weakened under a condition that a user takes an error symptom as a reasoning condition; a correct symptom participates in the reasoning operation by combining the correlating relationship between the error symptom and the convention symptoms according to the error symptom condition so as to realize the correctness and interruption resistance of reasoning; and a hospital department list is obtained by utilizing the mapping relationship between the disease and the department. The method can be used in electronic reception or health consulting systems, as well as in medical training or clinical reference.
