摘要： A high energy transfer relay includes a housing, a solenoid, a pivot arm, a stationary contact, a switching contact and a leaf spring. The switching contact is mounted on the leaf spring. The armature of the solenoid is coupled to the pivot arm such that when the solenoid is energized, the pivot arm moves in the direction of the stationary contact. Movement is against the force of the leaf spring which is positioned to bias the pivot arm away from the stationary contact against a stop. The leaf spring also pre-loads the pivot point. In addition, the resilience of the leaf spring cushions the impact of the switching contact on the stationary contact to help prevent contact bounce. The outer end of the pivot arm includes a flat that coacts with a flat wall to form an air cushion. The air cushion also assists in preventing contact bounce by absorbing the momentum of the pivot arm after the contacts mate. Additionally, the moment of inertia of the pivot arm and associated elements located on the switching contact side of the pivot point is counterbalanced by the moment of inertia of the armature and the part of the pivot arm on the solenoid side of the pivot point. Balancing the moments of inertia ensures that an acceleration force applied to the solenoid side of the pivot point will be counterbalanced by an equal and opposite force on the switching contact side of the pivot point.
摘要翻译：高能转移继电器包括壳体，螺线管，枢转臂，固定触点，开关触点和板簧。开关触点安装在板簧上。螺线管的电枢联接到枢转臂，使得当螺线管通电时，枢转臂沿固定触点的方向移动。运动抵抗板簧的力，其被定位成将枢转臂偏离固定接触件抵靠止动件。板簧还预先装载枢轴点。此外，片簧的弹性缓冲开关触点对固定触头的冲击，有助于防止触点反弹。枢转臂的外端包括与平坦壁共同构成气垫的平面。气垫还有助于通过在接触配合之后吸收枢转臂的动量来防止接触反弹。此外，位于枢转点的开关接触侧的枢转臂和相关元件的惯性力矩通过电枢的惯性矩和枢转臂的枢转点的螺线管侧的部分平衡。平衡惯性矩确保施加到枢转点的螺线管侧的加速力将通过在枢转点的开关接触侧上相等和相反的力平衡。

摘要： A battery pack (28) for a portable defibrillator (30). The battery pack has a latch (34) that is biased in an extended position. When the battery pack is inserted into a battery well (30) in the portable defibrillator, the latch automatically latches into a slot (124) to secure the battery pack in tile battery well. Ridges (112) are provided on the floor (108) of the battery well to reduce the friction between the battery pack and the floor of the well as the battery pack is inserted into the defibrillator. A ridge (38) is also provided around the periphery of the top (36) of the battery pack to reduce the friction between the battery pack and the ceiling of the battery well. A right wall (44) of the battery pack is inclined from vertical so that a cross section of the battery pack is trapezoid in shape. The asymmetric cross-section prevents the battery pack from being incorrectly inserted into the battery well. The disclosed battery pack construction simplifies the replacement of the battery pack in the portable defibrillator.

摘要： An external defibrillator (8) with an output circuit (14) having four legs arrayed in the form of an "H" (an "H-bridge") is disclosed. Each leg of the output circuit contains a solid-state switch (31, 32, 33, 34). By selectively switching on pairs of switches in the H-bridge, a biphasic defibrillation pulse may be applied to a patient. The switches in three of the legs of the H-bridge output circuit are preferably silicon controlled rectifiers (SCRs). Gate drive circuits (51, 53, 54) are coupled to the SCRs to bias the SCRs with a voltage that allows the SCRs to remain turned-on even when conducting low current. The switch in the fourth leg is preferably a pair of insulated gate bipolar transistors (IGBTs) coupled in series. A gate drive circuit (52) is coupled to the gate of the IGBTs to provide a slow turn-on and a fast turn-off of the IGBTs. The gate drive circuit (52) also biases the IGBTs with a sufficient voltage to allow the IGBTs to withstand a shorted discharge of the external defibrillator through the output circuit.

摘要： In an external cardiac defibrillator (8), a method and system for determining when a relay (22) has failed in a conductive state. The defibrillator (8) includes a charge circuit (14) that charges an energy storage capacitor (C) to a predetermined voltage. The relay (22) is closed to direct a defibrillation pulse from the energy storage capacitor to a patient (25) needing ventricular therapy. The relay (22) is then opened following application of the defibrillation pulse. A monitor circuit (18) monitors the voltage on the energy storage capacitor. If the measured voltage across the energy storage capacitor (C) is less than or equal to a threshold value after a predetermined delay, the relay (22) has failed. If the measured voltage exceeds the threshold value, the relay (22) is operating correctly.

摘要： An environmentally insensitive device is described. The device uses a passive paper guide to direct an output paper stream from a paper source contained within the unit to an output aperture. The passive paper guide uses two opposing surfaces to define a radius of curvature through which the paper strip is guided. Use of longitudinal ridges along one or both of the surfaces reduces friction along the guide. By providing a rotatable output cover over the aperture and using a unit cover, a printed output can be achieved while maintaining the shielding of the unit from environmental effects.

摘要： A bifurcated electrical connector (14) includes a precordial lead connection site (18) and a limb lead connection site (16). A precordial connector (26) can be fitted into the precordial lead connection site (18) and a limb lead connector (32) can be fitted into the limb lead assembly connection site (16). The force required to separate the limb lead connector from the limb lead connection site is greater than the force required to separate the precordial lead connector from the precordial lead connection site. Additionally, a cover flap (75) covers the precordial lead connection site when the precordial electrodes are not in use.

摘要： A method and system for automatic or semi-automatic defibrillation using redundant processing is provided. In a preferred embodiment, two microprocessors each separately analyze electrocardiogram signals from a patient in order to separately determine whether the patient should be treated. If both microprocessors determine that the patient should be treated, a treatment subsystem defibrillates the patient by delivering a defibrillation charge to the patient. In a semi-automatic embodiment, the treatment subsystem only delivers a defibrillation charge to the patient if a human operator has responded to a visual indication that the patient should be treated by manually activating the defibrillator.

摘要： A cardiac pacing apparatus and method. A cardiac pacing apparatus (24) provides a cardiac pacing signal to a plurality of electrode pairs (20, 22), each comprising a positive electrode (20a, 22a) and a negative electrode (20b, 22b). A plurality of isolated current sources (30, 32) supply the electrode pairs with separate electric pacing currents, each small enough in magnitude so as to avoid patient discomfort or burning. The plurality of pacing currents delivered to the electrode pairs add to produce a total cardiac pacing current of sufficient magnitude to cause contraction of a heart muscle through which the pacing currents flow.

摘要： A system (10) is disclosed that includes a monitor (16) for use in performing 12-lead electrocardiographic (ECG) and body surface mapping (BSM) analyses on a patient (12) with a single ten-electrode cable set (14). The monitor receives nine leads of data from the electrode cable set and initially preprocesses it to simplify further analysis. Then the data is transformed to produce a spatial distribution relative to the patient's chest, representative of the data that would be collectible with a 192-electrode set. Feature extraction techniques are also described for use in evaluating transformed, as well as conventional, BSM data with respect to clinically evaluated populations. In that regard, features of interest are extracted from the data and statistically analyzed to detect select cardiac conditions.
