Description

Robotic Mannequin Training and Simulator System
FIELD OF INVENTION
This invention relates in general to medical training simulators, and more particularly, to an intelligent, interactive neonatal training simulator employing a robotic mannequin.
BACKGROUND OF INVENTION
The APGAR score is the very first test given to a newborn infant, and it occurs right after the baby's birth in the delivery or birthing room. The APGAR score is a daily routine in delivery rooms across the United States and in many other countries. Virginia Apgar, M.D., developed the APGAR score in 1953 as a way to provide medical science with an objective method of observation and evaluation of a newborn infant's need for resuscitation immediately after delivery.
The test is routinely performed at one minute and again at five minutes after birth. Typically, one qualified person in the delivery room evaluates the infant using five signs in an objective, standard and measurable method. The five factors observed and scored after birth are heart rate, respiratory rate, reflex irritability, muscle tone and color. Each factor is scored on a scale of 0 to 2 and the factor scores are summed to calculate the APGAR score. Although 10 is the highest possible score, babies almost never receive it because the hands and feet of even healthy newborns are usually still slightly bluish 5 minutes after birth.
In determining the APGAR factors, the first sign tested is heart rate. An infant with a heart rate between 100-140 receives a score of two. A heart rate under 100 receives a score of one, and if the heart beat is absent, a score of zero is assigned. In determining the second factor, respiratory rate, an infant who breathes and cries forcefully receives a score of two, while one with irregular breathing a score of one, and an infant not breathing receives a score of zero. The third factor, reflex irritability, is determined as a response to physical stimulation. Physical stimulation may include suctioning the throat or nose or tapping on the foot. An infant who responds by coughing or turning away from the stimulation receives a score of two. An infant that responds with a facial grimace scores a one, and a non-responsive infant receives a score of zero. Muscle tone, the fourth sign, is determined by observing the activity of the infant. An active infant with flexed arms and legs receives a two. One with extended arms or legs receives a one and a completely limp infant receives a score of zero. In determining the fifth factor, the color of the skin is observed. A completely pink infant receives a two. An infant with a pink body and blue extremities receives a one, and an infant with an overall bluish-gray color receives a zero. As such, the total number of points available in the APGAR score is ten, with each of the five factors having a maximum value of two.
It has been shown through research that the APGAR score is a predictor of the need for resuscitation. A score of four or below one minute after birth indicates the need for prompt diagnosis and resuscitation. When resuscitation is deemed necessary, the score can then be taken again five minutes after resuscitation has been initiated to evaluate how the baby is responding to the resuscitation.
Neonatal resuscitation skills are essential for all health care providers who are involved in the delivery of newborns. The transition from fetus to newborn requires intervention by a skilled individual or team in approximately 10% of all deliveries. Of specific concern are the 81% of babies in the United States that are born in non-teaching hospitals in delivery rooms where personnel experienced in high-risk deliveries are unavailable.
Respiratory distress and extreme prematurity are the two complications of pregnancy that most frequently require a complex resuscitation by skilled personnel. Approximately 80% of low birth weight infants require resuscitation and stabilization at delivery. Nearly one half of newborn deaths, many of which are extremely premature infants, occur during the first 24 hours following birth. A number of these early deaths also have a component of asphyxia and/or respiratory depression as an etiology. For the surviving infants, effective management of respiration in the first few minutes of life may influence long-term outcome.
Obviously, accurate APGAR scoring and competent performance of neonatal resuscitation is of major importance in the effort to prevent infant deaths at the time of delivery. A neonatal resuscitation course available through the American Heart Association and the American Academy of Pediatrics entitled, Textbook of Neonatal Resuscitation, provides the materials and training necessary for health care professionals to perform successful neonatal resuscitation. To develop the accuracy and competency required by delivery room personnel, in addition to the training materials and guidelines, it is necessary to provide a training mechanism that provides a life-like situation for demonstration, teaching and rehearsing skills. The incorporation of a life-like neonatal resuscitation and APGAR scoring simulator will result in improved skill acquisition and retention and ultimately improved outcomes of actual neonatal resuscitation.
Neonatal resuscitation training simulators are known in the art. One such system is described in U.S. Patent No. 5,509,810 to Schertz et al., incorporated herein by reference, in which an intelligent, interactive neonatal resuscitation training simulator and method employing an infant android of life-like appearance and response is provided. While Schertz provides a training mechanism for neonatal resuscitation, Schertz does not describe a method whereby the APGAR score of a newborn can be determined. The infant android described by Schertz does not possess the features necessary to determine all five factors essential for the APGAR scoring.
Therefore, a need exists in the art for a life-like neonatal training simulator possessing the elements necessary to instruct medical professionals in the proper techniques for determination of the APGAR score for a newborn infant and to train and evaluate neonatal resuscitation skills.
However, in view of the prior art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the pertinent art how the identified need could be fulfilled.

A need exists in the field of teaching mannequins for a mannequin possessing improved life-like behavior. The need for more realistic models that mimic both physiologic and behavioral symptoms is a real necessity in modern day teaching systems. In the case of humans, many of the necessary diagnostic procedures must be performed on moving patients and this adds a considerable dimension to the educational program. If the student learns only with the use of flaccid mannequins, then the actual conditions that are faced in reality can present a difficult situation that the student has been unprepared to address. The ability to perform the functions necessary for diagnosis of a living patient is critical to the success of the student.
One instance wherein a life-like teaching mannequin is of particular importance is the neonatal milieu. At present devices that are used in teaching neonatal resuscitation are rudimentary and non-lifelike. One of the key skills required by delivery room personnel is the determination of an APGAR score for a newborn infant. Therefore, a simulation mannequin for the purposes of training personnel in the delivery room in the performance of the APGAR scoring system is provided. In training to determine an APGAR score, it is necessary that the simulation mannequin provide an audible heartbeat, simulated resuscitation, simulated muscle tone, simulated movement and simulated skin color.
The interactive training simulator of the present invention is a robotic system providing an integrated electromechanical, optical, chemical and pneumatic system. The robotic mannequin offers an airway to simulate endotracheal tube placement and audible and palpable heart rate to simulate normal and abnormal cardiovascular changes. In addition to this the invention can simulate color changes through the use of filtered light internal to the mannequin, simulating states common to the newborn both in normal circulatory transition and distress states, as well as muscle tone and reactivity typical of normal and distress states. The invention makes it possible to evaluate all the physiologic parameters as described by the APGAR scoring system. Furthermore, the simulator can mimic appropriate responses to drugs through the fluidic lines embedded throughout the cavity of the mannequin and connected via an umbilical. The robotic system also contains a recording device for real-time evaluating and playback of an individual trainee's performance. The robot's construction and control is derived from the APGAR scoring system. The system contains a suite of custom mechanical components and actuators, electronic control and signal processing hardware, structural material and sensor fabric and sensor networking as part of the requirements for operation. Software routines for control of the behavior of the robot, and non-deterministic interaction of the robot with a user are a key feature of the invention.
The instant system of the invention is considered to be a robotic system and is comprised of mechanical, electromechanical, optical, chemical and pneumatic systems. These systems are housed in a robotic mannequin and are connected to an interactive control system via an interface module and are responsive to a software program run on a computer controlling the interactive control system. This software program regulates the movements of the mannequin in addition to collating the feedback from the sensors of the mannequin to measure the appropriateness of the activities of a trainee.
With reference to Figure 1, in which is shown a functional block schematic of the system of the present invention 20. A user interface 1 provides a network-enabled computer, allowing both collaborative instruction and remote monitoring. The computer provides the user interface to the user. In the preferred embodiment the computer is preferably a laptop type of computer, since that type is most suitable for portable systems. Any such computer may be used as known to those of ordinary skill in the art. The computer system may also include a display monitor and a printer for retrieval of the results.
A custom user interface is supplied to present and control the various sensor and actuator systems. The controller interface to the mannequin is established through an interface module 10. The interface module 10 being an input/output digital and analog multi-channel card. The digital and analog inputs and outputs are configured so as to permit the sensing of the embedded sensors and provide feedback control for the actuation of movement. The interface module 10 provides an intelligent, interactive communication channel between the interactive control system 5 of the present invention and the robotic mannequin, represented by the block 15. Within the block 15 are provided rigid skeletal members 16, flexible muscle members 22, fluidic lines 18, embedded light sources 24, sensors 20, a motion system 27 and an audible pulse generator 26. Included within the sensors 20 of the robotic mannequin are included, magnetic intubation sensors 28, lung pressure sensors 30, lung mass airflow sensors 32, chest/touch pressure sensors 34, ventilated humidity sensors 36, flexible temperature sensors 38, solid-state chemical sensors 40, and accelerometers 42.
As shown in Figure 2, the robotic mannequin 15 is controlled by the user interface 1 through the interactive control system 5 utilizing the input/output capabilities of the interface module 10. Supplemental software that creates chaotic, unpredictable movement 44 and response 48 of the robotic system is also integral to this system to realize lifelike movement and behavior. This randomized, life-like behavior is implemented through a centralized pattern generator 46. The centralized pattern generator 46 comprises a mathematical, or cellular automata based simulation of a network of neural oscillators used for movement control. The pattern generator translates the computer commands into muscle control. Additionally, the pattern generator is dynamically configurable to provide either random or prescribed patterns on demand to establish lifelike movement of the robotic mannequin. The computer is network capable and can be controlled and monitored from a remote monitoring site. Entirely wireless systems are also possible within the scope of the instant invention, with the power supply in the mannequin being battery operated and the sensors relaying the information via suitable wavelengths to the interactive control module.
A key feature of the robotic system is the reliance on microelectromechanical systems (MEMS) based sensors for sensor function due to size constraints of the smaller format mannequin. As shown in Figure 3, a plurality of sensors 20 are provided within the robotic mannequin. The sensors 20 being in circuit communication with the interface module 10 through a plurality of electrical connections 50 throughout the body of the mannequin. While a variety of sensors are employable by the present invention, those integral to the operation include a magnetic intubation sensor which may be of the giant magnetoresistance (GMR) type, which sensitively senses the presence of magnetized material such as a magnetized insert within the airway tube. A humidity sensor is strategically placed in a ventilated channel to give proper operation of the humidity sensor. A lung pressure sensor is of the silicon micromachined type and can detect changes in the pressure state of the artificial lung apparatus. Similarly, an micromachined airflow sensor is used to measure the mass airflow to the lung region. Multiple, flexible style temperature sensors are distributed throughout the body to give localized, focused temperature measurements. An optional sensor to insert is a solid-state pH chemical sensor in the umbilical cable that holds both pneumatic working fluid and electrical cabling. For tactile sensing and chest force distribution during resuscitation exercises a touch pressure sensor array is provided to sense the pressure across the chest area.
Micromachined accelerometers are also embedded within the mannequin to create an ability to sense motion of the body and impulse force delivered by a user. The sensor network 20 is coupled to an interface module 10 to establish intelligent, interactive control by a user.
The key distinguishing feature of this arrangement of miniature sensors needed for this small format mannequin is the creation of a simulator environment for the APGAR rating system used in the neonatal health professional field and in addition for the creation of a real-time, life-like simulator for resuscitation training and practice.
In addition to the sensor network 20 provided by the robotic mannequin 15, the robotic mannequin 15 also employs an audible heart beat simulator 26, as shown in Figure 4. The heartbeat simulator being in circuit communication with the interface module 10. Evaluation of the heartbeat is an essential element in the determination of an APGAR score and in the determination of the need for resuscitation.
As shown in Figure 5, the robotic mannequin 15 includes a plurality of custom embedded light sources 24 to create controllable skin color for recreating health states and permitting the color aspect for APGAR color rating. The light sources 24 are in circuit communication with the interface module 10 through lines 52 and are controlled by the interactive control system 5.
As shown in Figure 6, fluidic lines 18 are embedded within the robotic mannequin 15 to provide a simulated drug delivery situation. The condition of the fluidic lines is controlled by the interactive control system through the interface module 10. With reference to Figure 7 and Figure 8, the robotic system of the present invention includes limb actuators using pneumatic muscles for life-like fluid motion. The rigid skeletal motion of the mannequin 15 is provided by skeletal members 16, which are driven by a motion system 27, controlled by the interactive control system 5 through the interface module 10. The skeletal members simulate the skeletal bone structure and joints 54 of an infant. The motion system provides movement through the use of a motor or equivalent motion-producing device capable of providing the torque necessary to produce the movements dictated by the interactive control system. In addition to the skeletal structure, as shown in Figure 8, the mannequin contains flexible muscle members 22, which serve to simulate the functions of actual muscles in the appendages of the mannequin 15. As detailed in Figure 9, the simulated muscle movement is provided using small pneumatic tubes 56 filled with air or other fluid in response to commands provided by the user through the interactive control system. An air or other fluid supply 58 is also connected to the muscle members 22 through the interface module 10 to supply the necessary fluid pressure for the pneumatic tubes 56. As shown in Figure 10, the tubes 56 may comprise a single member, or a plurality of members may also be used as shown. By virtue of this system, the instant mannequin is able to mimic programmed normal or abnormal movements, thus enabling the trainee the ability to learn in an environment that simulates actual, life-like conditions. In a further embodiment, the entire skeletal and muscle systems are comprised of pneumatic members. Additionally the entire movement apparatus, including the skeletal members and flexible members may be constructed from electromechanical parts without the use of any pneumatic devices.
All of these systems described above are interconnected with each other and the computer user interface via the interface module 10. The computer program servces to direct the motion of the muscles as well as the simulated bone members along with the plurality of physical sensors to display specific conditions. As manipulations are made to the mannequin, the computer program also serves to produce feedback which is sent to a printer or video device, and additionally provides parameter adjustments as treatment is effected.
As shown in Figure 11, a method of determining an APGAR score as disclosed by the present invention includes providing a robotic mannequin resembling a human infant 60, physically simulating within the robotic infant a condition corresponding to a newborn infant 62, evaluating the simulated heartbeat of the robotic mannequin 64, evaluating the simulated respiration of the robotic mannequin 66, evaluating the simulated reflex irritability of the robotic mannequin 68, evaluating the simulated muscle tone of the robotic mannequin 70, evaluating the skin color of the robotic mannequin 72, and assigning a score to each evaluated element to provide an APGAR score 74 as is known in the art.
Additionally, as shown in Figure 12, when based on evaluated heartbeat and respiration of the robotic mannequin, it is determined that resuscitation is necessary, an additional step is provided wherein resuscitation is performed 76. After resuscitation an additional APGAR scoring is performed to evaluate the effectiveness of the resuscitation procedure.
The novel interactive training simulator of the present invention provides a teaching tool utilizing sensor arrays and simulated life-like motion. The features of the present invention provide the necessary elements for a teaching device for APGAR scoring and resuscitation training.
Although the instant device is capable of simultaneous motion and physical parameter display, it is also contemplated that the instant device be utilized as a teaching mechanism absent the motion and the motion added in a second tier of study for learning progression flexibility.
Although described with respect to an infant system, the instant invention is applicable to a variety of human and other animal species mannequins.
