    Specification. Junod's Impts. in Vacuum Apparatus for the Relief of Inflammatory Diseases, arm, leg, or thigh of a patient, leaving the hand, foot, or other parts exposed. The fourth part of my improvements consists in forming vacuum apparatus for the leg or arm in several parts or sections, and in connecting them in the 5 manner herein-before described, by which means they may be packed within each other so as to occupy but little space. The fifth part of my Invention consists in forming abdominal vacuum appa¬ ratus with several internal chambers communicating with each other in order to obtain additional surface contact with the superficial tissue when under the 10 influence of the vacuum process. The sixth part of my Invention consists in adapting vacuum apparatus of this character to the neck by constructing it in the form of a collar combined with a hood of india-rubber to prevent the entrance of aii-, and so as to leave the face of the patient exposed.. 15 , The seventh part of my improvements consists in the application of an improved vacuum gauge to the air pump or instrument, employed for with¬ drawing or exhausting the air from vacuum apparatus, such as herein-before described, in order to indicate the extent of the vacuum required to be produced. Heretofore I have employed an ordinary vacuum gauge con- 20 listing of a glass tube containing quicksilver to indicate the pressure upon a divided scale, but this instrument was expensive, inconvenient, and liable to be broken, and the form of instrument I prefer to employ for this purpose according to this part of my improvements consists of a small case containing a spring which moves a pointer or needle in front of a circular dial plate, a 25 flexible diaphragm being interposed between the vacuum passage and the part connected with the spring and pointer; or a simple vacuum gauge may be made by covering a spiral spring with air-tight tissue, the same being caused to expand or contract according to the degree of vacuum required, which is indcated by a pointer attached to the gauge. 30 The last part of my present improvements consists in arranging vacuum apparatus so that a number of patients may be treated simultaneously in order to economize time where a number of patients require treatment. For this purpose a number of instruments or apparatus are connected by means of flexible tubes to other tubes communicating with the receiver of an air pump 35 or exhausting apparatus situated in any convenient part of a building or hospital, by which means one physician is able to superintend upwards of twenty patients with but little more trouble than attending upon one. Stop cocks are applied in connection with each apparatus, in most cases placed in the hand or within reach'of the patient to regulate the action as required, and
