Abstract
Description
Technical field
[0001] The present invention relates to an IHHT device (interval hypoxia-hyperoxia therapy device) for the controlled inhalational administration of gases or gas mixtures.
[0002] For the purposes of this application, an IHHT device is understood to be a device in which a user is alternately supplied with oxygen-poor and oxygen-rich breathing air in order to simulate changing oxygen concentrations such as those that occur during stays at different altitudes.
[0003] The IHHT device can be trained to be stationary or mobile. State of the art
[0004] Known IHHT devices use electronic chemical sensors to measure oxygen concentration. These sensors are subject to wear and tear due to use and age and must be replaced regularly, especially during maintenance. Object of the invention
[0005] The object of the present invention is to provide an IHHT device in which a maintenance-free sensor unit is provided for detecting the oxygen concentration. Solution to the task
[0006] This problem is solved by an IHHT device with the features of claim 1, in which an ultrasonic sensor is used instead of a chemical sensor. Advantages of the invention - No sensor replacement required during maintenance - Reduction of ongoing operating costs - high long-term stability - Robust measurement without chemical reaction Brief description of the drawing Fig. Figure 1 shows a circuit board with an electronic circuit unit and a sensor unit in an IHHT device. Example of implementation
[0007] The IHHT device comprises a printed circuit board (1) which is fixed by means of fastening elements (2). Connectors (3, 7), electronic components (4, 6) and an electronic circuit unit (8) are arranged on the printed circuit board (1).
[0008] Furthermore, a sensor unit (9) is provided, which is designed as an ultrasonic sensor. The ultrasonic sensor (9) serves to indirectly determine the oxygen concentration of a gas mixture.
[0009] The measuring principle is based on the fact that the speed of sound in a binary gas mixture changes depending on the concentration ratio of the gas components. The electronic circuit unit (8) evaluates the signals detected by the ultrasonic sensor (9).

[0010] The invention relates to an IHHT device for the controlled inhalational delivery of gases or gas mixtures with varying oxygen concentrations. Instead of a chemical sensor, an ultrasonic sensor is provided, which indirectly determines the oxygen concentration via the speed of sound in a gas mixture. The ultrasonic sensor is maintenance-free and does not require regular replacement, thereby reducing maintenance and operating costs.
