    Junod's Impts. in Vacuum Apparatus for the Relief of Inflammatory Diseases, years since, but owing to the expensive character of the apparatus it has not hitherto been extensively used, and one of the objects of my present imj^rove- nients is so to reduce the cost of the apparatus that it may be brought within the reach of all who may require its application. The first part of my Invention consists in connecting a series of vacuum 5 cups or chambers by means of a flexble air tube, such cups or chambers being suitably arranged for application to the back or other part. From twenty to thirty or more of such vacuum cups may be thus combined together in the form of a “ chaplet,” the whole series being exhausted by means of one air pump. The second part of my improvements consists in forming vacuum apparatus for the arm at such an acute angle that painful pressure upon the point of the elbow is prevented, the instrument so formed affording support to the arm around the elbow without giving pain to the patient, thus avoiding the objections attending the use of similar apparatus of the form hitherto adopted. 15 The application of vacuum apparatus to the arm of a patient as previously adopted has been painful and difficult, but by forming it so that it ran be placed at an angle pointing upwards according to this part of my improve¬ ments all the difficulties hitherto attending its use are avoided. This form of apparatus is constructed with a joint or connection at the elbows ^0 The third part of my improvements relates to vacuum apparatus applicable to the leg of a patient. The india-rubber muff*' or sleeve hitherto employed for connecting the instrument to the limb was so stout as frequently to cause pain to the patient, but if not of considerable strength is liable to burst when in use, and in order to obviate this difficulty and expense I employ a “ muff” ^5 or sleeve of silk or other woven fabric as a lining introduced within a sleeve of comparatively thin and soft india-rubber, thus imparting strength to the india- rubber and preventing pain from too great pressure caused by using stout india-rubber; or the india-rubber may be protected from bursting inwards by a collar of metal or other material of sufficient strength, such collars in some 30 , f. cases being capable of expanding in order to adapt them to limbs of different * size. Much difficulty has been experienced in adapting vacuum apparatus of this character to the legs of different patients, owing to the varying dimen¬ sions of the limbs, and this part of my improvements consists in the application of a ring or collar to the mouth or top of the apparatus so as to adapt the 35 instrument to legs of large or small circumference without inconvenience to the patient* A similar adjusting ring or collar may be used in combination ' with vacuum apparatus applied to the arm of a patient. Apparatus of this character may be constructed suitable for being applied to part only of the
