fig1 schematically shows a defibrillator , having a base unit 1 that contains a set of defibrillator electronics , with an electrode arrangement 2 connected to it via a connecting line 15 , which arrangement includes defibrillation electrodes and can also have measurement electrodes if needed or an integrated sensor system for measurement signals to be picked up from the patient , for example ekg signals , as is intrinsically customary in such defibrillators that can be externally worn by a patient . the connecting line 15 , which has a number of wires , is electrically connected to the base unit 1 either permanently or by a plug . the set of defibrillator electronics of the base unit 1 is divided into a plurality of submodules that are advantageously associated with various defibrillation components such as an energy storage unit with one or more capacitors , a charging device for the energy storage unit , a switch arrangement for forming the defibrillation pulse , a set of control electronics , an ekg amplifier , a signal analysis circuit , an hv output stage , and a user interface . additional components can include , for example , communications modules ( gsm modules , umts modules ), a gps module for locating the patient , or components of a human / machine interface . the submodules are connected to one another electrically via connecting lines 16 and mechanically via a flexible coupling such as a flexible support 18 ′, accommodated in respective secondary covers 10 , 11 , 12 , 13 , 14 , and form a combination that is interconnected in a functionally reliable fashion via the flexible electrical and mechanical coupling and that is arranged in a planar form in the exemplary embodiment shown in fig1 . fig2 shows an exemplary embodiment for a combination of submodules , with the secondary covers 10 , 11 , 12 , 13 , 14 arranged in a row in which the submodules are connected via connecting lines 16 to a bus line 17 with a suitable number of wires and are mechanically coupled , for example , by a flexible support 18 ′. in the additional exemplary embodiment according to fig3 , the submodules with their secondary covers 10 , 11 , 12 , 13 , 14 are mechanically connected to one another in a chain - link fashion by the mechanical coupling 18 , which are embodied in the form of flexible coupling means such as flexible plastic , a textile , or elements that are hooked to one another and are electrically connected to one another via connecting lines 16 . the individual secondary covers 10 , 11 , 12 , 13 , 14 can be embodied in various ways , for example as strong , relatively rigid flat plastic housings or as flexible receiving pockets made of a plastic material and / or woven material . they can be suitably adapted in shape and with regard to body compatibility and are designed as flexible and / or soft in order to adapt to various situations in life , such as for good mobility or for a person who is resting . in addition , the material can be suitably selected for gentleness to skin , for absorption of body temperature or perspiration , or for allowing said temperature or perspiration to pass through . in addition , a moisture protection for the electronics contained in the secondary covers can be achieved by correspondingly moisture - proof material and moisture - proof closures . on the whole , it is thus possible on the one hand to assure a high degree of wearing comfort and on the other , to assure a reliable functionality . fig3 shows a series - arrangement of the secondary covers 10 , 11 , 12 , 13 , 14 , which are electrically connected to one another via electrical connecting lines 16 and are mechanically coupled to one another in chain - link fashion via elastic or interlinked coupling means 18 . advantageous embodiments can be achieved through special embodiments of the installed components , such as by using flat capacitors without housings , by varying the chain , such as by subdividing the link chain , by installing the components in a vest , or by forming them into a two - dimensional chain link lattice . fig3 a and 3b schematically show more details of a series arrangement in the form of a link chain , with essential components of the structure , including an element housing 1 with a plurality of secondary covers in the form of housing modules a , b , c ( chain link b such as for a capacitor block 30 ) that are movably coupled to one another in the form of a chain . for example , on a supporting base 50 , the chain link b has a cup - shaped bottom part 20 for a capacitor block 30 and the electrical connection is produced by flat conductors 40 with appropriate contact points 60 . by way of example , fig3 a and 3b show the embodiment of a still - open housing module b with an appropriate submodule for a capacitor block and its connection to the two adjacent modules a and c . the drawings do not show the still - needed closure of the submodule by a for example welded cover . correspondingly , the housing module can also accommodate other components selected from among those mentioned above or from still other components . in an arrangement of the submodules of the defibrillator electronics in housing modules a , b , c that are connected to form such a link chain , a belt that is formed with the link chain can also be used , for example , to position electrodes . the above - described embodiments of the defibrillator base unit 1 with the submodules , which are contained in the secondary covers 10 , 11 , 12 , 13 , 14 and are connected to one another to form a flexible mechanical combination via the flexible mechanical coupling means and electrical connections , achieve a spatial separation of individual functional units of the main defibrillator devices so that the defibrillator is convenient to wear , particularly over the long term . it is also possible for individual functional units , such as the main voltage capacitor arrangement , to be subdivided to a greater or lesser degree into a plurality of modules . on the whole , this achieves an ergonomic adaptation of the defibrillator as a composite system to the body of the wearer . an embodiment in which the submodules are mounted onto a flexible support material 18 ′, such as made of a cohesive flexible plastic or fiber composite such as a textile , likewise permits a planar arrangement or series arrangement of the submodules , thus permitting an ergonomically favorable adaptation to the body of the wearer . the electrical connecting lines of the submodules can be integrated into the support material 18 ′, for example by textile cables with stable electrical properties or by flexible printed circuit boards . in an advantageous embodiment , the support material 18 ′ can be in the form of a protective cover and the secondary covers can be in the form of pockets in the support material so that the electrical connecting means and / or the defibrillator electronics are accommodated in them in a protective fashion . here , too , it is possible to produce the electrical connection to a bus system with definite lines that are separate from the high - voltage lines and can then be contacted individually by the submodules when they are attached support material . the flexible arrangement of the individual submodules in the composite permits an advantageous ergonomic adaptation of the defibrillator system to the wearer .
a defibrillator for permanent external application to a patient , with a protective shell arrangement receiving a base unit with defibrillator components , an electrode arrangement connected or connectable to the shell arrangement , and a support device . an ergonomic adaptation to the person wearing the defibrillator is achieved by the defibrillator components being spatially combined into subsidiary modules , and the shell arrangement has several subsidiary shells to which the subsidiary modules are distributed and which are movable relative to one another and connected to one another mechanically and electrically .
