Brachial-pulse wave recorder. This instrument serves for recording pulse curves with a certain, exactly adjustable pressure of the upper arm. So the curve may result the same in different times by the measurement with the same pressure. The clearest curve results next to the minimum pressure, i.e. a little below that one, and the sphygmographic one results to be the same. The inflatable cluff M is put tightly around the upper arm and the connection is closed like the image shows. The air pressure is produced with the horizontal adjustment of the cock H by the blower G. The compressed air blows up the inflatable cluff and the rubber ball, that is encased in a glass balloon (Erlanger Kapsel), the manometer indicates the compressed air. The air, that is displaced by B, escapes through the rubber plug, that is removed before. To record the curves the cock has to be set into its vertical position, so that the recording capsule T is connected with the encased air of the glass balloon, meanwhile the sleeve is contacting the ball B.
The manometer has to be isolated by K 2 and the external air has to be isolated by L.
The minimum pressure is determined by the popular method of Riva-Rocci (n° 3100). For the simple recording of the pulse the manometer is not necessary. The valve V serves to let off the air pressure.

Cardigraph according to Sanderson. The apparatus rests with three hard rubber legs at the chest wall, which are standing still when the screws are turning; the apparatus is fixed by strings around chest and neck. The pressure of the truss pad spring is regulable by a set screw; the air capsule may also be moved up and down without turning itself. 0,220 kg.

Spirometer according to Wintrich. (Cyon XXVII.) for the measurement of the exhaled volume of air. The apparatus consists of a graduated equilibrated bell jar, which is dipping into a vessel filled with water. The air is let directly to the bell jar through a pipe, so that the bell jar is lifted and the respiratory volume is indicated by the bell jar level above water.
The apparatus is made of zinc sheet and mounted on a tripod. For circa 250 ccm content, for animal experiments. 2,000 kg.

? Plethysmograph according to Mosso, for recording the tube connection is substituted by an s-shaped bowed metal tube, of which the upper stop cock leads to the arm cylinder n° 3040 and the lower stop cock leads to the regulating buret. The roll is bearing the loaded recording pipes and the small test tubes, it is worked out very exactly and rests frictionless on the friction wheels, so that it reacts to the finest variations. It is height-adjustable, turnable around its axis und fine adjustable against the recording drum by a micrometer screw. A plumb is hanging inside the hollow pipe of the tripod, the apparatus is exactly adjustable in vertical positions by set screws. 4,800 kg.

Plethysmograph according to Lehmann. The zinc sheet arm cylinder is surrounded by thick cotton-wool padding. Inside the cylinder a sack corresponding to the arm of fine soft rubber material is fixed upon the open end of the tube. The filling is done by the supply cock after inserting the arm in the rubber sack. The water is filling the space between the metalic cylinder und the rubber sack und rises in the unscrewed glass pipe of 10 cm height, from which a rubber tube is leading to the recorder. To increase the pressure the glass pipe has to be exchanged to one of 25 cm height. The elbow is adjustable by an inholsterd rest on the scale. The entire apparatus may be hanged up by chains and combined with the device n° 3042 with great advantages. Without special specifications the metal cylinder has a circumference of 31 cm and a length of 32 cm (see n° 3051-3054). The apparatus serves also as hydrosphygmograph if the cock leading to the water gauge bottle remains open. 3,100 kg.
