Spirometer (18) and sampling connector (2) are manufactured so that, in operation, they make up a single unit which is linked via outflow tubes 6 and 7 to pressure and/or flow measuring elements (12, 13) as well as via a sampling tube (9) to a gas analyzer (10). A microprocessor adjusts the flow rate in accordance with the composition of the gas as determined by the gas analyzer.

Abstract: A shock-wave curative apparatus is provided with a second imaging probe, which is disposed outside a shock-wave applicator, in addition to a first imaging probe. The first imaging probe collects mode data of a human body, and is movably located at substantially the center of the shock-wave applicator. The second imaging probe is located outside the shock-wave applicator, and manually collects mode data of the human body from the outside of the shock-wave applicator. The first and second imaging probes are connected through a select switch to a mode data processing section. The select switch selectively makes either of the first and second imaging probes ready for use. The processed mode data is displayed by a display means.

Abstract: A method and apparatus are described for determining characteristics of peripheral arterial volume and compliane. A blood pressure cuff is inflated and deflated around a limb of the body and pressure measurements are taken. The volume of air removed from the cuff is determined in a quantifiable manner, such as by expelling air through an orifice of known characteristics or by means of a volume of know characteristics. The detected pressures and volume of air removed are used to compute oscillation volume, which in turn is used to display arterial capacity and compliance as a function of transmural pressure and time. Arterial capacity may be displayed in terms of arterial radius, arterial cross-sectional area, or arterial volume. A display of these characteristics as a function of pre and post anesthetic administration is particularly useful to the anesthesiologist and surgeon.

Abstract: A method for testing for dysfunctional discs in which a spinal contact member contacts a disc under a low force to obtain the position of the contact member with the disc in its normal or usual unstressed position, the same disc is contacted with the contact member under an elevated increased standard force to obtain a second position of the contact member, and the two positions are compared to determine the condition of the disc. A complete contour of the spine is obtained and recorded. Apparatus used includes a roller which bears against the spine and rolls from disc to disc with the roller being mounted on a vertical calibrated rod. Means are provided to vary the pressure applied to the rod.
