Patented Sept. 30,1952 '7 1 This invention relates to anatomical supports and, is directedQmOre particularly to"fulcrum blocks for the treatment of'patients.
'I'he principal object'sfof the'invention'aredirelated more particularly to improvements in anatomical supports constructed and arranged tofunction as a fulcrum fo'r'the sacroiliaclregion of the body asi weli as for relaxing spinal muscles and normalizing j oint action and, other tre n s v. i. v
The, support of the nvenitioii is characterized by an elongated base which is relatively rigid and having a yield'ab'leintermediate layer thereon with an upper relatively more yieldable layer,
aiding and correcting various conditions. For instance, with the support placed transversely beneath the back 'of a-patient insupine position, there is a relaxing of spinal muscles an dvv ertebrae and pelvic segmentsate'nding to normalize jointaction as the doctor rocksthe patient pn the support to bring about movement in the area of the spine.
With the block support placed beneath the patient, sacroiliac joint fixations may be freed for the correction of spinal subluxation, or when disposed beneath the neck the muscles of the neck are relaxedin cases of neuralgic headaches.
The support; has met with much success in the treatment of various conditions and when disposed beneath the back of a patient there are no unfavorable stresses applied to the joints, all of which is due to the novel constructions of the support.
All of the above objects I accomplish by means of such structure and relative arrangements of parts thereof, as will fully appear by a perusal of the description below and by various specific features which will be hereinafter set forth.
To the above cited and other ends and with the foregoing and various other novel features,
and advantages and other objects of my invention as will become more readily apparentas the- 'The support has been found to be useful for mediate layer and, is

The material of the intermediate layer 4 may I rubber of a character having more yieldability and resiliency than the intermediate layer 4.
Other materials may be employed for the layers 4 and 6 which will provide the relative yieldability and resiliency and the layers may be secured together by cementing if desired. Likewise the intermediate layer may be secured to the base The relative yieldability of the layers is important for the reason the yieldabiiity of the intermediate layer supported by the base is necessary for the desired functioning of the device while the relatively more yieldable and resilient upper layer obviates such stresses and strains on the joints as might unfavorably afiectthem and the desired functioning of thedevice. In other words, the intermediate layer is yieldable for the proper functioning of the device but the patient is cushioned by the upper layer against any unfavorable action of the less yieldable lay'r thereher being formed from material relatively more below. yieldable and resilient than that of said base As a special feature of the invention, the upper member and said upper member being formed surface of the intermediate layer is provided with from material relatively more resilient and yield- -a transverse groove I disposed intermediate the able than that of said intermediate member. ends of the device. 2.
