Embodiment Construction

[0053] Figure 1A A perspective view of a breathing tube holder 1 is shown as a holding device for pulmonary function diagnosis. This snorkel holder 1 comprises an inner snorkel space 2, the snorkel (in Figure 1A (not shown in ) can be inserted into the inner breathing tube space 2 for pulmonary function diagnosis and can be removed after use. The inner breathing tube space 2 serves as the inner main space of the breathing tube holder 1 . Said inner main space is delimited by the main body 3 of the breathing tube holder 1 .

[0054] On a first side of the body 3 a first ultrasonic transceiver housing 4 is arranged. On a second side opposite to the first side a second ultrasonic transceiver housing 5 is arranged. The first ultrasonic transceiver housing 4 may also be denoted as a first side body. The second ultrasonic transceiver housing 5 can also be denoted as a second side body. When the breathing tube holder 1 is in operation, one ultrasonic transceiver is inserted int...

Abstract

The invention relates to a holding device for a breathing tube used in pulmonary function diagnosis. It is characterized in that the holding means (1) comprises a material which is transmissive for light with a wavelength in the first wavelength range, but not transmissive for light with a wavelength in the second wavelength range. In other respects, the invention relates to a pulmonary function diagnostic device comprising such a holding device (1), to a novel use of selectively transmissive materials in the manufacture of such a holding device (1), and to a device for reading out Method for coding (15) on the surface of a breathing tube (14) for pulmonary function diagnosis.

Description

technical field [0001] The invention relates to a holding device for a breathing tube in pulmonary function diagnosis according to the preamble of claim 1 and to a holding device equipped with such a holding device according to the preamble of claim 11 Pulmonary function diagnostic device, relating to a novel use of a selectively permeable material according to the preamble of claim 14, and to a device for reading the method of encoding. Background technique [0002] The use of breathing tubes (also known as tubes) to measure the gas inhaled and / or exhaled by a patient is common in lung function diagnostics. EP 3 017 760 A1 describes such a breathing tube. This European patent application also describes a comb-shaped indicator on the breathing tube as a coding element. Furthermore, this European patent application describes the readout of comb structures by light sources and corresponding detectors. [0003] It has been observed that the reliability of reading such comb-...
