Embodiment Construction

[0029] figure 1 , 2, 3, 4, 5 shows the air bag inflation device 1 includes a syringe 2, a pressure measurement module 3 and a tube 3A.

[0030] The syringe 2 extends along the axis X—X, and mainly comprises a syringe body 4 and a piston 6, the volume of the syringe is preferably 20 cm 3 .

[0031] The syringe body 4 made of transparent plastic comprises a tube section 8 from which a side box 10 of the same material as the tube section forms a protrusion. Box 10 is open.

[0032] The front end of the syringe body has a narrower diameter neck 12 disposed at the end of a converging section 14 that elongates the tube section. The fixing system comprises a deformation mechanism 14 holding the connector and sealing means 16 formed, for example, of a sealing gasket.

[0033] The syringe piston 6 is formed by a rod 20 fitted through the rear end of the syringe body 4 into the tube section 8 and having a head 22 at the end with a gasket which slides sealably within the syringe body...

Abstract

An air flushing device of airbag comprises a syringe (2) which includes a syringe body (4) and a syringe piston (6) which can slide and rotate. The syringe piston (6) is provided with external screw thread. The syringe body also comprises a detachable mechanism (30) which holds the syringe piston (6) in the syringe body. The detachable mechanism (30) can be interchanged in the detached state and active state. In the detached state, the syringe piston (6) slides freely. The syringe piston (6) can not slide freely in the active state. Furthermore the syringe piston (6) can be screwed in or out in the active state. The device also comprises a pressure meter (104) for measuring the outlet pressure of syringe body (4). The pressure meter (104) is installed around the shaft of syringe body (4) and can move with an angle relatively to the syringe body (4).

Description

field of invention [0001] The present invention relates to a device for inflating an air bag, such device comprising a syringe comprising a syringe body and a syringe piston slidable and rotatable in said syringe body, the piston having an external thread over at least part of its length, The syringe body also includes a detachable mechanism for retaining the plunger in the syringe body, said mechanism being interchangeable between a detached state in which the plunger slides freely in the syringe body and an active state The piston is not freely slidable, and the piston can be screwed into and out of the syringe body, and the device includes a manometer to measure the outlet pressure of the syringe body. Background technique [0002] These inflatable devices are used to inject fluid into a balloon that is pre-deflated within a patient's artery or vein. Devices of this type are described, for example, in document US-A-5,147,300 or in document FR-2,850,286. [0003] These d...
