Definitions
- the invention relates to a device comprising a tubular sheath associated with a so-called dilator tube, for placing a catheter tube in a vein after introduction of the device by the so-called Seldinger method.
- This method involves the following operations:
- the publication FR-A-2439591 describes on the other hand such a tubular sheath (5), which has over its entire length an elastic slot (6), the distal end (7) of which has been blunted and which is threaded on a dilator tube (1) whose distal end (3) is tapered.
- the expression “elastic slit” means that the lips of the slit can deviate from each other, but return to each other when the cause which has caused this separation has ceased.
- the distal ends of the dilator and the sheath undergo a treatment: the dilator is tapered to obtain a slope whose distal diameter is closest to the diameter of the guide. the sheath is blunt to adjust it to the outside diameter of the dilator.
- FIG. 1 of the attached drawing which reproduces FIG. 1 of this publication the sheath and the dilator are shown separately while in FIG. 2 of the drawing which reproduces FIG. 2 of the publication, the sheath is threaded on the dilator. Blunting the sheath is a delicate operation. It is indeed necessary to keep a distal dish (step) to avoid the reversal of the sheath in the passage of tissue.
- the present invention aims to avoid these drawbacks.
- a device which comprises a sheath which has a cylindrical running part and which is split over its entire length by an elastic slot, this sheath being threaded on an dilator tube which has a cylindrical running part and a tapered distal end, which has the following features:
- the distal end of the tube is connected to the current part of the tube by a shoulder projecting from this current part, the cylindrical current part of the sheath ends in a distal section which is flared forward, - the shoulder of the tube follows the distal edge of the sheath.
- the sheath opening opens to allow the shoulder of the dilator to pass and resumes its initial (closed) shape after complete withdrawal.
- FIG. 1 is an axial section of an exemplary embodiment of a device comprising a sheath and a dilator according to the present invention.
- FIG. 4 shows an elevation (FIG. 4A) and is a section (FIG. 4B) of the distal ends of the sheath and of the dilator of the device of the invention, and
- FIGS. 3 to 6 are enlarged views respectively of one elevation and of the section of Figure 4, and - Figure 7 is an elevational view corresponding to that of Figure 5 but during the withdrawal of the dilator.
- the device represented in FIGS. 3 to 6 consists of: - a cylindrical tubular sheath (11) split longitudinally at (12) over its entire length and provided at its proximal end (that is to say which will be close to the manipulator) of a fin (13) intended to facilitate its handling.
- the sheath is made, in a manner known per se, in a material such that the slot can open under the effect of passage inside the sheath of an element with an external diameter greater than the internal diameter of the sheath, and closing itself after removal of this element, what has been referred to above as sheath elastic slit.
- the sheath is a polyurethane tube whose internal / external diameters are included in the 1.5 / 5.5 mm ranges. - a cylindrical dilator tube (14) provided with a proximal connection base (15) and whose distal end (16) is tapered.
- This tube is made of synthetic resin, for example polypropylene.
- the distal end (16) of the dilator tube is connected to the cylindrical running part (14) of the tube by a shoulder (17) projecting from this running part.
- This shoulder can be any, but preference is given to a frustoconical shape whose cross section decreases from front to back, as is the case in the example shown.
- the edge (18) of the distal end of the sheath (11) has a frustoconical shape flared towards the front in relation to that of the shoulder so as to match the shoulder.
- the external diameter of the current part of the tube (14) is chosen to be substantially equal to the internal diameter (dl) of the sheath (11) so that the sheath is threaded onto the tube with a certain friction while the diameter (d2) of the tube at the top of the shoulder is chosen equal to or slightly greater than the outside diameter (d3) of the sheath so that the sheath does not project outwardly from the shoulder.
