Embodiment Construction

[0037] in figure 1 The respirator shown in has an air inlet 1 and an air source 2, and the respirator has an outer cover 10 for protection. The air source 2 is preferably constructed in the form of a blower or a compressor. It is also possible to use an internal or external accumulator or an external compressed air supply device as the air source 2. An adjustable inspiratory control valve 3a, an inspiratory flow sensor 4a, and an inspiratory pressure sensor 5a are provided in the upper pipeline for patient inhalation. At the end of the pipe is connected an inhalation hose 6 leading to the patient. The air outlet hose 7 is connected back into the housing 10 from the patient. An expiratory pressure sensor 5b, an expiratory flow sensor 4b, and an adjustable expiratory control valve 3b are also provided in the lower pipeline for controlling exhalation. The measured values ​​of the flow sensor and the pressure sensor will be continuously transmitted to the control device 8, where...

Abstract

The invention relates to a respiratory device for keeping a patient breathing artificially or support his or her breathing naturally. Said respiratory device comprises an air inlet, an air source, and at least one proportionally adjustable control valve. The control valve is provided with a housing (11) and a rotary valve (12) which is arranged in the housing so as to be twistable about the longitudinal axis thereof and which allows through-holes (11d) of the housing (11) to be entirely or partially closed by twisting the rotary valve (12). The rotary valve (12) and a corresponding support surface (11f) of the housing (11) have a conical shape, the support surface (11f) cooperating with the rotary valve (12). The through-holes (11d) are disposed in the area of the support surface (11f).

Description

Technical field [0001] The present invention relates to a valve used for flow control and regulation of a respirator. The valve has a housing and a rotary slide valve rotatably arranged in the housing around its longitudinal axis. The rotary slide valve can be completely rotated by rotating the rotary slide valve. Or partially close at least one through hole, the rotary slide valve has a tapered sealing surface that cooperates with a correspondingly designed housing support surface, and the through hole is arranged in the range of the sealing surface. Background technique [0002] The respirator can be used in fixed areas (such as clinics or homes) or in mobile areas (such as emergency services). One of the most important is that this appliance can operate safely, reliably and without failure. In order to avoid the impact on the surrounding environment when using this appliance, it must be as quiet and stable as possible during operation. [0003] US 6,615,831 discloses a respira...
