The present invention relates to the field of providing healthcare consultation to human patients. More particularly, the present invention relates to a system and method for remotely connecting healthcare providers and human patients with a multi-disciplinary consulting team of healthcare consultants throughout a geographically dispersed area via a remote assistance unit or robotics and video conferencing systems or other suitable means. The present invention also relates to a wearable computer capable of two-way audio/visual conferencing to provide 24/7 real-time healthcare consultation.
Medicine is evolving through changes in technology and improved methods of delivering healthcare. New technologies and processes enhance the ability of connecting users and suppliers of healthcare.
For example, critical care medicine is undergoing rapid changes due in part to financial limitations, a shortage of intensivists (a physician who specializes in the care and treatment of patients in intensive care units (ICUs)) and nurses, and information overload. Care of critically ill patients consumes a disproportional amount of national medical healthcare dollars (greater than 1% of the GDP). Studies have shown that ICUs with intensivists have reduced ICU costs, hospital costs, mortality rates and lengths of stay in the ICU and the hospital. Moreover, improved patient recovery has been linked to care directed by trained intensivists. Intensivist-directed care has been demonstrated to be superior to traditional care with multiple specialists. However, the current supply of qualified intensivists is inadequate to meet demands. Attempts have been made to address this issue.
U.S. Pat. No. 6,852,107 to Wang, et al., discloses a medical system that allows a mentor to teach a pupil how to use a robotically controlled medical instrument. The system can include a first handle that can be controlled by a mentor to move the medical instrument. The system can further have a second handle that can be moved by a pupil to control the same instrument. Deviations between movement of the handles by the mentor and the pupil can be provided as force feedback to the pupil and mentor handles. The force feedback pushes the pupil's hand to correspond with the mentor's handle movement. The force feedback will also push the mentor's hand to provide information to the mentor on pupil's movements. The mentor is thus able to guide the pupil's hands through force feedback of the pupil handles to teach the pupil how to use the system.
U.S. Pat. No. 6,850,817 to Green discloses a teleoperator system with telepresence that includes right and left hand controllers for control of right and left manipulators through use of a servomechanism that includes a computer. Cameras view workspaces from different angles for production of stereoscopic signal outputs at lines. In response to the camera output a 3-dimensional top-to-bottom inverted image is produced which is reflected by mirror toward the eyes of operator. A virtual image is produced adjacent control arms, which is viewed by the operator looking in the direction of the control arms. By locating the workspace image adjacent the control arms, the operator is provided with a sense that end effectors carried by manipulator arms and control arms are substantially integral. This sense of connection between the control arms and end effectors provide the operator with the sensation of directly controlling the end effectors by hand. By locating the visual display adjacent control arms, the image of the workspace is directly viewable by the operator. Use of the teleoperator system for surgical procedures is also disclosed.
U.S. Pat. No. 6,804,656 to Rosenfeld, et al., discloses a system and method for providing continuous expert network critical care services from a remote location. A plurality of intensive care units (ICUs) with associated patient monitoring instrumentation is connected over a network to a command center which is manned by intensivists 24 hours a day, 7 days a week. The intensivists are prompted to provide critical care by a standardized series of guideline algorithms for treating a variety of critical care conditions. Intensivists monitor the progress of individual patients at remote intensive care units. A smart alarm system provides alarms to the intensivists to alert the intensivists to potential patient problems so that intervention can occur in a timely fashion. A data storage/data warehouse function analyzes individual patient information from a plurality of command centers and provides updated algorithms and critical care support to the command centers.
U.S. Pat. No. 6,356,437 to Mitchell, et al., discloses an apparatus and method for providing a user with task-specific information that includes a portable instruction system that may be worn by a user, and includes, a computer sufficiently lightweight and designed to be worn by a user to which a memory has been connected. The system includes a display device that can receive display signals from the computer for visual display to the user and an input device by which the user enters commands to the computer. An instructional program is provided that the computer accesses and stores in memory in response to a user command and displays information concerning a task to be performed by the user on the display device in response to commands from the user.
U.S. Patent Application Publication No. 2002/0143580 to Bristol, et al. discloses a software-based environment that uses data communication systems or networks, including the Internet and World Wide Web technologies, to implement a dosage calculator, which assists the clinician in managing patients receiving intrathecal therapy. Medical professionals require integrated data to manage their patients. Implantable drug pumps can supply robust data associated with the drug pump. The invention provides for a communications environment for clinicians, pharmacists, drug pump manufactures, and patients to assess not only the information supplied by an implantable drug pump, but also integrate data from other data sources. The invention provides for an inexpensive and practical way for a physician to review the performance parameters of an implantable drug pump in a patient to provide optimization of the life of the drug pump and the therapeutic substance formulations for the patient.
