摘要:
The invention relates to a device for measuring patient compliance with oxygen therapy, including a casing (4) comprising means for detection of the oxygen therapy in order to evaluate data relating to the treatment; and means for measuring a state of physical activity of the patient. Preferably, the means for measuring a state of physical activity of the patient comprise at least one sensor which senses movement of the patient's body and outputs data relating to the spatial displacement of the patient's body, for example a three-dimensional accelerometer (28); and processing means (40, 42) for processing the body displacement data in order to supply a state of physical activity of the patient chosen from a sleeping state, a resting state and an active state.

This invention provides a support arrangement for suspending a piezo-elecc resonator which by providing a frame with cut out portions in its interior enables a resonator provided with suspension conductors to be placed in position by simple translation or rotation without in any way distorting the suspending conductors. Accordingly, the invention is well adapted to modern mass production methods.

In the controlled and stabilized platform (1) comprising a plurality of optical apparatuses, the optical apparatuses (8, 9, 10) are mounted in a casing (7) which is pivotable about a sight axis (12) in a bearing (13) which is pivotable about a bearing axis (14), the casing (7) and the bearing (13) being controlled about their axes (12) and (14) by motors (40) and (38) actuated by detectors measuring variations in the angular position of a stabilized input mirror (11) which reflects radiations going to the optical apparatuses or coming from the latter.

A piezo-electric resonator comprises a rectangular piezo-electric bar moud interiorly of a frame formed of a multi-layered insulating material. The frame is impermeably enclosed by two cover members. The frame comprises a fastening arrangement including a suspension formed of thin conductors attached to the bar and arranged along one or more lines in the plane of one face of the bar. The thin suspension conductors are fixed to the face of the bar along nodal lines and are elbowed at least once on each side of the bar. The layered frame has a special construction.

The invention relates to an apparatus (2, 4) for tracking a treatment for obstructive sleep apnea, including a gas passage (10) and a Venturi tube (16) having a cylindrical inlet (40) and outlet (42), said Venturi tube (16) being axially arranged in said gas passage (10), a first pressure sensor (101), and a second pressure sensor (102). The diameters (D1) of the inlet (40) and outlet (42) of the Venturi tube (16) are between 10 and 25 mm. The Venturi tube (16) includes, arranged in series between said inlet (40) and outlet (42), a convergent portion (44) having the shape of an arc (46, 48), a cylindrical neck (50), the diameter of which is smaller than the diameter (D1) of the inlet (40), and a divergent portion (52) characterized by an angle of divergence (α) of between 5° and 15°. The invention also relates to equipment for treating sleep apnea, which includes a pressurized-gas source (6) connected to a breathing mask (8) via a gas duct (30), as well as to an apparatus (2, 4) according to the invention, which is arranged between said gas source (6) and said breathing mask (8).
摘要:
An installation for exchanging gas cylinders includes an enclosed space preferably with controlled access, at least a couple of stations, one for depositing an article to be exchanged and the other for collecting an article to be taken away, each station having a device for retaining the article that can be switched between an open configuration and a locked configuration, the retaining devices of the two stations being coupled such that the locking of one retaining device around an article to be deposited in the deposit station authorizes at least temporarily the opening of the retaining device of an article to be taken away for its removal.
