Patent DE-4126028-A1 (DE)
Inventor: LANG VOLKER PROF DR
IPC: A61M16/00
Filed: 1991-08-06
Abstract: The invention relates to a device for heating and moistening respiratory gases with a small volume of dead space which is especially suitable for giving artificial respiration to premature and newborn infants and children. This device consists of three parts, whereby part (1) and part (2), largely made of metal, are interconnected in a housing and form a connecting component combined with an active steam-sterilisable moistening and heating device into which part (3), a one-time heating-moistening exchanger insert, is fitted. The upper third of this insert (3) acts as a passive heat-moisture exchanger which premoistens and preheats the dry respiratory gas on inspiration (about 30  DEG C, 100 % relative humidity) and the central and lower third of which, supported by the active moistening and heating with the aid of the active heat-moisture device (1, 2-17), finally undertakes the optimum conditioning of the respiratory gas (36-37  DEG C, 100 % r.h.). On expiration, 60-80 % of the moisture and heat of the optimally warm and damp respiratory gas is recovered by the heat-moisture exchanger insert (3) primarily via its upper third away from the patient. In cases of great respiratory difficulty, e.g. in very small premature infants, the volume of dead space of the device can be reduced still further by opening an air outlet stub in part (3).

Abstract: The invention relates to a method for measuring and monitoring the course of solidification of a coagulum in the coagulating process of milk for the production of coagulated milk products, in which the force required for the propulsion of a test piece moved through the setting milk is used to evaluate the solidification state, the course of solidification being measured directly in the process vessel, the optimal coagulum cutting time point being determined completely automatically in this case, and information on the time point in the production process being intended to be made available as a control signal. For this purpose, it is provided in terms of the process that, from the data of the course of solidification, the position of a first relative maximum and a second maximum is determined and, after the second maximum is reached, a control signal is triggered. An arrangement for carrying out the process is equipped, inter alia, with a measuring device (2) having a measurement carriage (2a) which transmits its forward motion via a measuring rod (2b), projecting into the interior of the process vessel (1), to the test piece (2d), the required propulsion force of which is measured via a force-recording apparatus (2c), the test piece (2d) being configured as a double cone or as a sphere or as a hemisphere whose flat boundary surface points in the direction of propulsion. <IMAGE>
