Abstract:
The invention relates to a method and a device for applying a shrink film sleeve (1) to a container (9). The method comprises the following steps: a) perforating of the shrink film sleeve (1) at predefined distances, b) expansion of the perforated shrink film sleeve (1) by means of an expansion device, in particular an expansion mandrel (3), c) transporting of the expanded shrink film sleeve (1) along the expansion device (3) having a conveyor roller pair (4a, 4b), d) tearing off of the shrink film sleeve (1) at the perforation with a downstream dispensing roller pair (5a, 5b), the transport speed (V tearing off) thereof being at least temporarily larger than the transport speed (V conveyor) of the conveyor roller pair (4a, 4b) and e) depositing the separated shrink film sleeve (1) onto the container (9).
Abstract:
A device for welding an IV tube into fluid communication with a lumen of a catheter comprises a grounded metal adapter which is operatively associated with a dielectric collet to clampingly engage and hold a catheter in the collet. The device further comprises a metal mandrel which is partially inserted into an IV tube and positioned so that part of the IV tube and mandrel extend into a portion of a lumen of the catheter. With the IV tube and mandrel positioned in the lumen, the dielectric collet is further engaged to compressingly urge the lumen sidewall into contact with the outer surface of the IV tube. RF energy is then applied to the mandrel to weld the IV tube into the lumen.
Abstract:
A flexible hose including a tube has an improved adhesion uniformity of tube to a hose unit and an improved quality. The flexible hose comprises a hose unit 1 and a tube 2 adhered to an inner wall of the hose unit, and the tube is adhered to the hose unit with a heat-generating adhesive member 3 which generates heat by an electromagnetic means and is arranged along a longitudinal direction of the tube. The heat-generating adhesive member 3 is preferably a linear member which generates heat by passage of a current to express an adhesive property. Further, the heat-generating adhesive member 3 preferably has a main body 31 comprising a non-heat-generating thermoplastic adhesive and a heating wire 32 embedded in the main body along a longitudinal direction of the heat-generating adhesive member 3.
Abstract:
A multi-lumen catheter and method of manufacturing such a multi-lumen catheter having a plurality of individual catheter tubes. Each catheter tube has an outer surface, an inner surface and a lumen. The catheter tubes can be made of different thermoplastic materials. A mandrel is first inserted into the lumen of each catheter tube to provide support. The catheter tubes are then juxtaposed to each other in an arrangement. Importantly, the outer surface of one catheter tube is in contact with the outer surface of at least one other catheter tube in the arrangement. The arrangement of catheter tubes is then held in a sleeve and is advanced through the sleeve, and through a heating cylinder to fuse the outer surfaces of the catheter tubes. A cooling means is placed in the lumen of each catheter tube to prevent the inner surface of each catheter tube from melting.
Abstract:
A flexible hydraulic element (1) comprises three conduits (10, 11, 12) suitable for conveying a fluid under pressure and a longitudinal portion (100) in which the axes (C1, C2, C3) of the three conduits (10, 11, 12) are arranged angularly spaced.
Abstract:
A tube-in-tube assembled parison for preparation of an elongated medical device. The parison if formed by assembling in tube-in-tube fashion a first tube of orientable polymer material and a second tube formed of orientable polymer material disposed around the first tube, with an adhesive tie layer disposed between the first and second tubes. The tubes are brought into contact to form a unitary parison. The adhesive may allow movement between the polymer layers during balloon blowing. The first tube, or the second tube, or both, may have been longitudinally pre-stretched after formation thereof but before assembly of the parison.
