  • Patent number: 7857625
    Abstract: Medical patient simulator comprising a torso (2) that contains an artificial lung (6), a chest skin (3) and means (8, 9) for pulling the chest skin (3) downward in an area corresponding with an area where such retractions occur on a human being. The simulator also provides for changes in the compliance of the lung (6). The lung (6) is situated between two plates (5, 7), the spacing of which can be adjusted. The torso (2) has one actuator (23, 24) on each side of the back to simulate muscular activity. It includes a system for control of pneumatic functions by measuring a representative pressure for each actuator and stopping the filling when a pre-set pressure is reached. It also includes a head with one or more air cushions in a fontanelle area on the head, which may be filled with air to simulate an increased pressure in the brain.

  • Patent number: 7837636
    Abstract: A transmission device transforms an alternate rotational movement of an alternately rotating element into a linear reciprocating movement. The device includes a linear reciprocating element connected to the rotating element, and a first pivoting element having a first fixed pivot point connected to the linear reciprocating element. The transmission device includes a second pivoting element connected to the first pivoting element. A ball member, which may be connected to a CPR piston, is attached to the second pivoting element. A third pivoting element having a second fixed pivot point is connected to the second pivoting element.

  • Patent number: 7802991
    Abstract: A device for practicing mask ventilation, comprising a first passage and a second passage. The first passage is designed to provide communication between a source of air and the interior of a patient mask. The patient mask is designed for placement over a person's mouth and/or nose. The second passage is designed to provide communication between the air source and a back pressure means. The back pressure means is adapted to simulate the resistance of a human airway. The device can also comprise a third passage designed to provide communication between a breathing person and the surroundings. The passages may be formed in one integrated adapter to be placed between a patient valve and the mask.

  • Patent number: 7731500
    Abstract: The illustrative embodiment is a simulation system for practicing vascular-access procedures without using human subjects. The simulator comprises a data-processing system and a haptics device. The haptics device provides the physical interface at which an end effector, which is representative of a medical instrument (e.g., a needle, catheter, etc.), is manipulated with respect to a haptics-device base to simulate instrument insertion. The data-processing system, by exchanging signals with the haptics device, provides a three-dimensional simulation that includes the resistive forces that a medical practitioner would experience if the simulated procedure were an actual procedure that was being performed on a real anatomy (e.g., human arm, etc.). The simulator displays the ongoing simulation and assesses the performance of its user.

  • Publication number: 20100036266
    Abstract: Embodiments are directed to a device and method for detecting heart beats and/or monitoring ventilation and/or respiration of a patient using air pressure. In one embodiment, a monitoring device comprises a gas duct and at least one pressure sensor configured to measure pressure in the duct. The duct may be in fluid communication with a patients airways. Based on the sensed pressure, a heart beat of the patient may be detected. In another embodiment, a flow rate of the air expired from the patient may be calculated based on the pressure and a known flow resistance.

  • Publication number: 20090215011
    Abstract: A method, computer system and computer program product for providing a computer simulation that provides advance notification of expected events or states, comprising running a first computer simulation; running a second computer simulation corresponding to said first simulation, said second simulation having progressed further than said first simulation; and using said second computer simulation to provide information representing expected future events in said first simulation. A first computer simulation may be based on a model of a simulated system, said model having a plurality of state variables. Input data from a first user input interface may represent user interaction with said first computer simulation, while input data from a second user input interface may represent the extent to which a condition should be present in said simulation.

  • Publication number: 20080314386
    Abstract: A ventilation device is disclosed including a self-inflating bag which when compressed produces an outgoing flow, an inlet and an outlet and at least one valve connected to the inlet and/or outlet. The valve is disposed to control the flow out of the air outlet. One or more sensors positioned to sense air flow through the inlet or outlet produce outputs that are used by a controller to control opening and closing of the at least one valve to reduce hyperventilation.

  • Publication number: 20080312565
    Abstract: The present invention provides a CPR sensor that includes a thin and substantially flat flexible substrate having one or more sensor arrays, a power source, an output interface and a processor or analog circuit, all of which are disposed on the substantially flat flexible substrate. The substrate can be any shape (e.g., rectangular, circular, a polygon, an irregular shape that is decorative) and made from a polymer, metal film or other suitable material. Note that the substrate can be rigid or semi-flexible instead of flexible. A protective layer may cover the sensor array, the power source, and the processor or analog circuit. Alternatively, a protective covering can be used to encapsulate the device. The one or more sensor arrays measure one or more of the following compressions characteristics: compression depth, compression force, compression frequency and compression acceleration.
