RESUSCITATION SIMULATOR WITH INSUFFLATION MEASUREMENT

摘要

A resuscitation simulator with an insufflation tube for artificial respiration by a helper and a Venturi tube joined to the insufflation aperture by a respiratory air-conducting connection. The Venturi tube has a first tube section, with the first inner cross-sectional area, and a second tube section, with a second inner cross-sectional area, with the second inner cross-sectional area smaller than the first inner cross-sectional area. The first pressure measurement is made on the first section of the tube, and a second pressure measurement is provided on the second section of the tube. A pressure measuring device is provided which is connected to the first measurement position and the second measurement position, with which a differential pressure between the first measurement point and the second measurement point can be determined. The pressure measuring device generates a pressure measurement signal from the measured value. This signal is transmitted to a signal pre-processing circuit, which develops a volume flow via the Venturi tube derived the pressure measurement signal.

1. A resuscitation simulator for reanimation attempts by a helper comprising:
an insufflation tube (2) for blowing in the helper's respiratory air, a Venturi tube (6) joined to the insufflation tube (2) by a respiratory air-conducting connection, with the first section of tube (13) having an inner cross-sectional area (A1) and a second section of tube (14) with an inner cross-sectional area (A2) which is smaller than the first inner cross-sectional area (A1), with a first pressure measurement position (16) in the first tube section (13) and a second pressure measurement position (17) in the second (14); and a pressure measuring device (12), with which the differential pressure between the first pressure measurement position (16) and the second pressure measurement position (17) is determined and which generates a pressure measurement signal, a signal pre-processing circuit, with which the pressure measurement signal derived from the Venturi tube (6) enables the calculation of the volume flow ({dot over (V)}1 {dot over (V)}2).
