    Abstract: A medical trainer simulator includes a plurality of simulated vessels filled with a conductive fluid representing, for example, veins or arteries. While performing a procedure using the medical trainer, a person inserts a medical instrument, e.g., a needle or scalpel, into a selected vessel, causing the medical instrument to contact the conductive fluid. A circuit board detects when a circuit is thus created by detecting an electrical current flowing through the medical instrument and the conductive fluid it has contacted. A software program executing on a computer excludes any phantom circuit occurring when the medical instrument contacts conductive fluid from a previous procedure that is not within one of the vessels. A phantom circuit is detected if the resistance of the resulting circuit exceeds a predetermined threshold. The computer visually and/or audibly indicates whether the correct vessel was pierced or excised by the medical instrument.

  • Publication number: 20140272872
    Abstract: A device for simulating blood flow including an anatomical unit and a waveform generator for generating waveforms. The waveform generator includes a pump capable of pumping a fluid through at least one fluid line and thereby transmitting the waveform from the waveform generator through the fluid line. The waveform generator further includes a bifurcation point capable of splitting the fluid line into additional fluid lines, where the fluid lines include a main line and a parallel line. Additionally, the waveform generator includes valves capable of at least partially occluding fluid flow. The device further includes a reservoir capable of housing the fluid, where the waveforms enter and exit the anatomical unit and the waveform generator through the fluid lines simulating blood flow.

  • Patent number: 8808004
    Abstract: Disclosed is a biological model for training which is in a tubular shape having an inner cavity, has a narrowing or closing portion at a mid portion of the tube, and is provided with a artificial lesion member simulating a lesion occurring in a tubular tissue. In this biological model for training, the artificial lesion member includes, at least in a portion thereof, a plastic and deformable material. The biological model for training is used in expansion training for implementing expansion. As the plastic and deformable material, a material including, as the main component, at least one member selected from among a silicone clay, a resin clay and an oil clay can be specifically used. Such a material is preferred because of ensuring the maintenance of a expanded state in the expansion training.

  • Publication number: 20140099620
    Abstract: A versatile multi-function modular pulse duplicator system having multiple modules each universally and fluidly connected to each other via universal connectors. Each module being detachable from another module and the plurality of modules can be rearranged in different sequence or quantity as the user desires for specifically designed hemodynamic simulations. Some modules have specific functions by having a pump, a compliance chamber, a resistance mechanism, or a fluid reservoir. Optional peripheral modules that simulate anatomical subsystems can be fluidly coupled within this system of modules, allowing studying/training/product demonstration in the subsystem specifically provided, under desired cardiovascular hemodynamics. The use of universal connectors, peripheral modules, and selectively attachable/detachable modules, make this a versatile system where a user can design a simulation according to the specifics needed for product testing, product demonstration, surgical training, teaching and researching.

  • Publication number: 20140057236
    Abstract: A surgery simulator includes a physical surrogate surgical interface that represents an interface between a user and a simulated patient in a simulated surgical scenario that involves manipulation of both simulated hard and soft tissue. Sensor(s) sense the user's manipulation of the surrogate surgical interface. A surgical simulation generator generates a real time 3D surgical simulation of the surgical scenario based on the manipulation sensed by the sensor(s). The real time 3D surgical simulation comprises real time simulation state data. The surgical simulation generator renders the real time simulation state data into a real time computer graphics generated video representation of the surgical simulation and provides the real time video representation to a display for real time viewing by the user. The surgical simulation generator simulates effects of the manipulation on both simulated hard tissue and simulated soft tissue of the simulated patient.

    Abstract: A monitoring device arranged to display a level of consciousness and hemodynamic parameters of a patient for simultaneous viewing. A dependence of changes in the hemodynamic parameters of the patient on the level of consciousness of the patient may be more easily observed using the monitoring device. Correlations between the patient's level of consciousness and the patient's hemodynamic parameters may further be determined and displayed to aid clinicians in estimating any improvement in hemodynamic parameters that may be achieved through manipulation of the patient's level of consciousness, fluid status and drugs.
