Integrated devices for performing external chest compression (ECC) and defibrillation on a person and methods using the devices. Integrated devices can include a backboard, at least one chest compression member operably coupled to the backboard, and a defibrillator module operably coupled to the backboard. The integrated devices can include physiological sensors, electrodes, wheels, controllers, human interface devices, cooling modules, ventilators, cameras, and voice output devices. Methods can include defibrillating, pacing, ventilating, cooling, and performing ECC in an integrated, coordinated, and/or synchronous manner using the full capabilities of the device. Some devices include controllers executing methods for automatically performing the coordinated activities utilizing the device capabilities.

Integrated external chest compression and defibrillation devices and methods of operation

Devices, methods, and software implementing those methods for providing communicating external chest compression (ECC) devices and defibrillation (DF) devices, where the ECC and DF devices can be physically separate from each other. Both ECC and DF devices are able to operate autonomously, yet able to communicate with and cooperate with another device when present. Some ECC and DF devices are adapted to be physically and/or electrically coupled to each other. One ECC device includes a backboard, a chest compression member, a communication module, controller, and at least one sensor, electrode lead or electrode. One DF device includes a defibrillator module, a controller, and a communication module that can communicate with the ECC communication module. The communicating ECC and DF devices may deliver ECC, pacing, defibrillation, ventilation, and cooling therapies, and may deliver instructions to human assistants, in a coordinated and cooperative fashion.

Cooperating defibrillators and external chest compression devices

In general, the disclosure presents techniques for rapidly cooling the body of a patient. A cooling garment is placed in contact with the body of the patient. Spacers within the cooling garment create a space between at least a portion of the cooling garment and the body of the patient. The cooling garment receives a coolant from a coolant supply and delivers the coolant to the body of the patient. The heat from the body of the patient may evaporate the coolant. A carrier gas, which circulates within the space between the cooling garment and the patient, carries the gaseous coolant out of the cooling garment via an exit port. The rapid cooling of the patient may slow the neurological damage to the patient.

Rapid induction of mild hypothermia

In general, the disclosure presents techniques for control of a cooling garment in response to a signal that is a function of a patient parameter such as body temperature. In particular, a cooling garment that receives a coolant and a carrier gas is placed in contact with the body of a patient. A sensor within the cooling garment may generate a signal as a function of a patient parameter. A controller receives the signal via communication link, and may send a signal to a regulator that may regulate delivery of the coolant and/or carrier gas, for example.

Feedback system for rapid induction of mild hypothermia

The invention is directed to techniques and apparatus for controlling the temperature of a coolant delivered to a patient in a hypothermic therapy system, including a hypothermic therapy system that can be applied to a patient outside or inside a hospital setting. In general, the coolant is in a pressurized form at ambient temperature, and is expanded proximate to the patient to cause the coolant to cool. Cooling garments placed in contact with the body of the patient circulate the cooled coolant proximate to the patient to cool the patient. A controller controls the temperature of the coolant by mixing the coolant with ambient air, for example, to reduce the risk of harm the patient.

Coolant control for rapid induction of mild hypothermia

A first electrical connector of an interface is provided on a floating plug assembly mounted on one component of a physiological instrument. A second electrical connector of the interface is mounted in a socket assembly constructed in another component that can be coupled to the first component by relative linear translation. Guides located in the socket assembly capture fingers on the plug assembly as the plug assembly is inserted in the socket assembly. The guides orient the plug assembly so that the first connector is correctly aligned with the second connector. The connectors are automatically joined as the first component is coupled to the second component.

Electrical interface for a portable electronic physiological instrument

A mechanical connector (10) for securing together an electrocardiogram monitor (12) and a defibrillator (14). The connector includes a tongue (16) disposed on a side surface (18) of the ECG monitor and a set of angle flanges (22) disposed on the defibrillator. A keyway (52) extends lengthwise at a rearward portion of a channel (36) between the tongue (16) and the side surface (18). A key (50) fits within the keyway (52) when the tongue (16) is slid within the set of angle flanges (22). The key (50) prevents the defibrillator from being fully coupled with an ECG monitor that lacks the corresponding keyway.
