Abstract: A defibrillator in which electrodes with a limited shelf life are stored largely out of view from the exterior of the unit, but the expiration date or other marking indicative of expiration or failure is positioned so as to be visible from the exterior of the defibrillation unit. A fracturable member is attached to the defibrillation unit so that opening the defibrillation unit requires fracturing the member, thereby providing an indication of whether the unit has been opened. Electrodes are releasably attached to the inside of the cover of a defibrillator, so that when the cover is removed the electrodes remain with the cover.

Abstract: Defibrillators are provided that include a graphical user interface to assist a caregiver in administering resuscitation.

Abstract: Electrode assemblies are provided, in which a pair of electrodes is joined by a central member. In some implementations, the electrode assemblies are foldable, and are configured to facilitate correct placement on a patient's chest. Some electrode assemblies include a separable electrode, allowing the electrode assembly to be fitted to patients having particularly large chests.

Abstract: Defibrillators are provided that include a passive airway support device.

Abstract: A power supply for supplying power from an external power source to a medical device for charging a battery of the medical device and operating the medical device includes an external power connection for bringing external power into the power supply, a power module having a power circuit that converts power from the external power source to a form useable by the medical device, monitoring circuitry for monitoring the external power connection to determine whether the external power connection is connected to a source of external power, and alarm circuitry for generating an alarm when the monitoring circuitry determines that the external power connection is not connected to a source of external power.

Abstract: A detachable power supply for supplying power from an external power source to a portable defibrillator for charging a battery of the portable defibrillator and operating the portable defibrillator includes a housing shaped to attach to the portable defibrillator and a latch connected to the housing for mechanically attaching the power supply to the defibrillator so that the power supply and the defibrillator form a portable, integral unit.

Abstract: A surgical clip applier includes a pair of pivotal housing sections on which are provided a pair of clip actuating jaws. An elongated clip sleeve which receives a plurality of surgical clips arranged front to back in a row is mounted for longitudinal reciprocating movement between the housing sections. The clip sleeve includes a pair of clip retaining jaws adjacent to its open front to receive and hold a surgical clip advanced from the clip sleeve between the clip actuating jaws on the housing sections. A pusher is mounted on the clip sleeve for engaging the rearmost clip in the row. The surgical clip applier includes a ratchet mechanism which is operable each time the clip sleeve is reciprocated to advance the pusher and the row of clips by one step corresponding to the length of one surgical clip in the row. The ratchet mechanism includes a first ratchet on the clip sleeve and a second ratchet on one of the housing sections which are engaged by pawls on opposite sides of the pusher.
