摘要： A delivery device for supplying a respirator with breathing gas includes a cylinder housing with a piston, and a drive unit for generating delivery strokes, which is connected to the piston via a piston rod. A compact design is achieved by providing the drive unit with a motor-driven hollow shaft with a spindle acting as a piston rod displaceable in it telescopically.

摘要： The invention is directed to a pumping arrangement for supplying a ventilating apparatus with breathing gas. The pumping arrangement includes a piston which runs in a cylinder and the piston is connected via a coupling with a drive unit for generating the pumping strokes. The coupling engages a motion transmitter in the form of a piston rod. Gas connecting ports for the breathing gas to be pumped open into the inner chamber of the cylinder. The pumping arrangement permits the piston-cylinder unit to be simply removed and to be reinstalled with reliable guidance. An automatic latching occurs such that a release and removal of the piston-cylinder unit from the ventilating apparatus and its uncoupling from the drive unit is possible only in a rest condition and not during operation. For exchanging the piston-cylinder unit, the motion actuator in the form of the piston rod moves through a preparatory stroke having an end position in which the coupling as well as the latching of the piston-cylinder unit with respect to the housing can be actuated.
摘要翻译：本发明涉及一种用于为通风设备供应呼吸气体的泵送装置。泵送装置包括在气缸中延伸的活塞，并且活塞通过与用于产生泵送冲程的驱动单元的联接件连接。联接器以活塞杆的形式接合运动变送器。用于呼吸气体的气体连接端口被泵送到气缸的内腔中。泵送装置允许活塞 - 气缸单元被简单地移除并且可靠的指导被重新安装。发生自动闭锁，使得活塞 - 气缸单元从通风设备的释放和移除及其与驱动单元的分离仅在静止状态下而不是在操作期间可能。为了更换活塞 - 气缸单元，活塞杆形式的运动致动器移动经过预备冲程，该预备冲程具有一个终止位置，在该位置中联动器以及活塞 - 气缸单元相对于壳体的锁定可被致动。

摘要： A respiratory flow sensor, which is suitable for use near a patient, covers a broad gas volume flow measuring range with a low breathing flow resistance and good, reproducible measured signal quality at the same time. The respiratory flow sensor has a first air resistance body (3) with a blunt end and with an opposite pointed end. The air resistance body (3) is arranged between the measuring transducer (5), of which there is at least one, and the patient-side end (P) of the respiratory flow sensor. The pointed end of the first air resistance body (3) points toward the measuring transducer (5). A second air resistance body (4) with a pointed end is arranged between the measuring transducer (5), of which there is at least one, and the end of the respiratory flow sensor that is away from the patient. The pointed end of the second air resistance body (4) also points toward the measuring transducer (5).
