Devices, systems, and methods appropriate for use in combat medical training are provided. In some instances, the combat medical simulators facilitate training of common field medical techniques including tracheostomy, wound care, tourniquet use, pneumothorax, cardiopulmonary resuscitation, and/or other medical treatments. Further, the combat medical simulators have joints that provide realistic ranges of motions to enhance the realism of the training experience.

An external defibrillator system is provided. The system includes: a graphical display; one or more sensors for obtaining data regarding chest compressions performed on a patient; and a controller configured to display on the graphical display numeric values for depth and/or rate of the chest compressions based upon the data from the one or more sensors. A method for using an external defibrillator including the steps of: obtaining data regarding chest compressions performed on a patient; and displaying on a graphical display screen of the defibrillator numeric values for depth and/or rate of the chest compressions based upon the data is also provided.

Described herein are methods for determining a target musculoskeletal activity cycle (MSKC) to cardiac cycle (CC) timing relationship. The method may include detecting a signal responsive to a cyclically-varying arterial blood flow at a location on a head of a user; providing a recurrent prompt at a frequency of the heart pump cycle using the signal, such that the signal correlates with a magnitude of blood flow adjacent to the location, and the recurrent prompt is provided to guide the user to time performance of a component of a rhythmic musculoskeletal activity with the recurrent prompt; and guiding the user to adjust a timing of the component of the rhythmic musculoskeletal activity to substantially maximize a magnitude of the signal. In some embodiments, the method further includes generating the recurrent prompt by amplifying the sound generated by the blood flow in or in proximity to an ear of the user.

A method and system for expediting the rescue of victims experiencing sudden cardiac arrest (SCA) when used in conjunction with an automated external defibrillator (AED). The system involves an apparatus that calls for help (i.e. 911), detects SCA and cardiac arrhythmias, locates an AED, guides the rescuer through CPR and connection of the AED. A second apparatus is in the enclosure that contains the AED, sends location information to the other apparatus, triggers audible and visual indicators, and provides information on the victim's location.

A training system and training method for cardiopulmonary resuscitation (CPR) is disclosed. The training system includes a manikin, a chest compression module, a breathing module and a data processing module. The chest compression module and the breathing module are installed on the manikin and connected to the data processing module. During a training session, a student performs CPR on the manikin. The data processing module evaluates and provides feedback regarding the chest compressions and the rescue breathings performed by the student. The training method includes positioning the chest compression module and the breathing module on the manikin, initializing the chest compression module and the breathing module to identify compression and breathing characteristics of the manikin, performing CPR on the manikin, and evaluating the CPR based on the compression and breathing characteristics of the manikin.

A surgeon training apparatus includes an operating table and an immersion tank carried by the operating table and configured to contain liquid. A thoracic animal tissue cassette is configured to hold at least harvested animal lung tissue for surgeon training. An inflator is configured to be coupled to the harvested animal lung tissue. An actuator is configured to relatively move the thoracic animal tissue cassette between an operating position above the immersion tank and an immersed position in the liquid within the immersion tank so that the surgeon can test the harvested animal lung tissue for leaks during surgeon training. The surgeon training apparatus may be at a first location at a first geographic point and a remote surgeon station may be at a second location at a second geographic point remote from the first geographic point to allow a remote surgeon to remotely train.

An ECG signal processing system which removes the CPR-induced artifact from measured ECG signals obtained during the administration of CPR.

A wearable medical device, comprising: a garment configured to be worn about a torso of a patient; one or more sensors for detecting a characteristic of a cardiopulmonary resuscitation (CPR) therapy; an output device; and a processor configured for processing information from the one or more sensors and providing, to the output device, information about the CPR therapy, wherein at least one of the one or more sensors is movably attached to the garment, the at least one sensor configured to be positioned to the center of the patient's chest prior to initiation of the CPR therapy.

A respiratory gating phantom device includes a first airbag, a second airbag, a first catheter, a second catheter, a fixture, and an air pressure gating device. The first catheter and the second catheter are respectively installed in the first airbag and the second airbag. The fixture is provided with a phantom tumor and adjustably installed in the first catheter or the second catheter, thereby installing the phantom tumor in the first catheter or the second catheter. The air pressure gating device, connected to the first airbag and the second airbag, inflates and deflates the first airbag and the second airbag to simulate breathing. The first catheter and the second catheter respectively move along three-dimensional direction and two-dimensional direction in response to motions of the first airbag and the second airbag.

A system for medical training includes an anatomical simulator modeled after at least a portion of a body, the simulator including at least one external surface, and at least one cavity in fluidic communication with the external surface via a cavity. The system further includes at least one internal sensor positioned at an internal location of the anatomical simulator, the internal sensor positioned to receive an internal input based on forces applied from within the cavity, at least one external sensor positioned at an external location of the anatomical simulator and to receive an external input based on forces applied to the external surface, and a feedback display system in communication with the sensors to simultaneously record external sensor readings from the at least one external sensor and internal sensor readings from the at least one internal sensor and at least one time measurement device.
