US Patent:

7731500, Jun 8, 2010
Filed:

Jul 8, 2004
Appl. No.:

10/887348
Inventors:

David Feygin - Washington DC, US
Gerald Higgins - Takoma Park MD, US
Chih-Hao Ho - Reston VA, US
Marjorie Moreau - Arlington VA, US
Ned Way - Columbia MD, US
Assignee:

Laerdal Medical Corporation - Wappingers Falls NY
International Classification:

G09B 23/28
US Classification:

434272, 434262, 434267
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.

Mar 23, 2004
Appl. No.:

10/807016
Inventors:

David Feygin - Washington DC, US
Chih-Hao Ho - Reston VA, US
Assignee:

Laerdal Medical AS
International Classification:

G09B 23/28
US Classification:

434262
Abstract:

The illustrative embodiment is a simulation system for practicing vascular-access procedures without using human subjects. The simulator includes a data-processing system and a haptics interface device. The haptics device provides the physical interface at which a user interacts with various mechanisms that are intended to enable the user to simulate various aspects of a vascular-access procedure. The haptics device is designed so that its physical form and manner of use are not inconsistent with the experience of performing an actual vascular access procedure.

Mar 23, 2004
Appl. No.:

10/806531
Inventors:

David Feygin - Washington DC, US
Chih-Hao Ho - Reston VA, US
International Classification:

G09B023/28
US Classification:

434262000
Abstract:

The illustrative embodiment is a simulation system for practicing vascular-access procedures without using human subjects. The simulator includes a data-processing system and a haptics interface device. The haptics device provides the physical interface at which an end effector (e.g., medical instrument, such as a needle, catheter, etc.) is manipulated to simulate needle insertion, etc. In some embodiments, the orientation of the end effector is sensed. In some embodiments, the end effector is reversibly couples to a force-feedback system, but not until the user does so.

US Patent:

20050214725, Sep 29, 2005
Filed:

Mar 23, 2004
Appl. No.:

10/807017
Inventors:

David Feygin - Washington DC, US
Chih-Hao Ho - Reston VA, US
International Classification:

G09B023/28
US Classification:

434262000, 434272000
Abstract:

The illustrative embodiment is a simulation system that provides realistic training and practice for vascular-access procedures without using human subjects. The simulator includes a data-processing system and a haptics interface device. The haptics device provides the physical interface for performing vascular-access procedures by manipulating a needle/catheter module to simulate needle insertion, etc. Some embodiments of the system include a palpation module, a skin-stretch module, or both. The palpation module provides an ability to practice palpation and occlusion techniques, while the skin-stretch module provides an ability to practice a skin-stretch technique.

US Patent:

20050214726, Sep 29, 2005
Filed:

Mar 23, 2004
Appl. No.:

10/807047
Inventors:

David Feygin - Washington DC, US
Chih-Hao Ho - Reston VA, US
International Classification:

G09B023/28
US Classification:

434262000
Abstract:

The illustrative embodiment is a simulation system for practicing vascular-access procedures without using human subjects. The simulator includes a data-processing system and a haptics interface device. The haptics device provides the physical interface at which an end effector (e.g., medical instrument, such as a needle, catheter, etc.) is manipulated to simulate needle insertion, etc. In accordance with the illustrative embodiment, the haptics device includes a receiver. The receiver receives the end effector when it's inserted by a user into the haptics device. Sensors that are associated with the receiver monitor the motion and position of the end effector, generate signals indicative thereof, and transmit the signals to the data processing system. The signals are processed to determine the effects of manipulation of the end effector. In some embodiments, the signals are processed to determine the various resistive forces that would arise if the user were manipulating a needle/catheter through actual human anatomy. Responsive to this determination, the receiver generates forces that the user experiences as a resistance to continued advance (insertion) of the end effector. Simulated results are displayed by the computer system.
