The present disclosure relates generally to closure mechanisms, such as a closure latch device for clamping a band. The closure latch comprises a first and second latch member engaged to pivot relative to each other. Certain embodiments relate to methods of clamping a band. Certain embodiments relate to methods of manufacturing a clamping device.

Closure latch

An electrotherapy delivery device includes an upper member having a handle portion and a pediatric electrode mounted to the bottom surface of the upper member. A base member having an adult electrode is selectively attached to the upper member with a coupling mechanism to conceal the pediatric electrode. The upper member attaches to the base member across diametrically opposed corners of the base member to provide the user with a more ergonomic hand position when accessing the paddles from the defibrillator. The device further include a plurality of switches operable to deliver a charge and to select the level of charge to be delivered to the patient. The paddle is provided with a processing circuit that receives an output from separate energy level increase and decrease switches, processes the output from the switches, and outputs a signal to the defibrillator corresponding to the level of energy selected by the switches.

A battery (10) contains a base portion (12) that is shaped generally rectangular parallelpiped. The bottom face (18) of the base portion (12) contains a raised notch portion (22) at the first end (14) of the base portion directly beneath an upper ledge (20) that extends along the perimeter of the first end. The first end (14) contains two keyed recesses (24) that extend from an upper ledge (20) to the notch portion (22) of the bottom face (18). A blade connector (26) is located between the two keyed recesses (24) at the intersection of the notch portion (22) and the first end (14). The bottom face (18) contains two apertures (28) for receiving pin shaped positive and negative cell terminals. The second end (16) contains a resiliently attached latch member (30). A corresponding battery well (40) contains opposite first and second ends (44) and (46), a bottom floor (48), and a rim portion (50) that extends along the first end. The bottom floor (48) contains a raised step portion (52) located directly beneath the overhanging rim (50) at the first end. The first end (44) contains two protrusions (54) that span from the step portion (52) to the overhanging rim (50). A blade connector (56) is located on the step portion (52) between the two protrusions (54) at the first end (44). The bottom floor (48) contains two banana plug cell terminals (58), near the second end (46). Three retractable contact pins (60) are aligned between the two banana plug cell terminals (58) in the bottom floor (48). The second end (46) contains an overhanging flange (62) that is bisected by a central indentation (64).
