Definitions

  • This invention relates to an improved device for securing catheters which are designed to be inserted into the spinal column (spinal catheters) or into the veins (venous catheters).
  • a catheter By positioning a catheter in the spinal column, it is possible to administer local anaesthetics and other drugs for surgical anaesthesia or pain- i killing purposes. If a catheter is inserted in a vein, drugs can be infused continuously for therapeutic purposes. As both approaches, ie. venous and spinal, require the catheter to remain in situ for long periods, sometimes for months, one of the major problems is obviously constituted by the need to secure the catheter firmly to prevent its displacement which, in addition to jeopardising the therapeutic effects, would expose the patient to a high risk of the drug's being delivered to tissues other than those in which the catheter was originally positioned.
  • the applicants have found that such a solution, though advantageous, can be improved on.
  • the aim of the invention is to perfect the device disclosed in the said international patent application no. PCT/EP00/07283 by improving the adherence of the rubber cylinder to the catheter and reducing the size of the device, so as to improve the patient's compliance. This aim is achieved by the invention with the characteristics described in the annexed independent claim 1.
  • the catheter securing device in accordance with the invention comprises a substantially flattened body with an adhesive base for firm application to the patient's body; the said flattened body has an internal cavity for the passage of a catheter and an externally threaded head with a smaller diameter, to which is screwed a hollow cap destined to house a rubber bushing with a central channel of a gauge proportional to the catheter, which said rubber bushing is suitable to lock the catheter without constricting it when the cap is screwed on.
  • figure la is a plan view of the body of the catheter securing device in accordance with the invention
  • figure lb is a view from below of the device shown in figure la
  • figure lc is a median section through plane I-I shown in figure la
  • figure 2a is a median section of a cap designed to close the body shown in figures la-c at the top
  • f ⁇ gure 2b is a view from above of the cap shown in figure 2a
  • figure 3a is an exploded median section of the device in accordance with the invention, which also shows a rubber bushing designed to lock the catheter in position
  • figure 3b is a median section of the assembled device, complete with catheter.
  • FIGS. 1 and in particular figures la-c show a body 1, conveniently made of plastic, which presents a substantially flat side 2 and a convex opposite side 3, which is substantially semi-cylindrical, sides 2 and 3 being joined by lateral wings 4 with rounded edges.
  • Flat side 2 which corresponds to the rear side of body 1 , is adhesive, or double-sided adhesive tape is fixed to it to ensure firm anchorage to the patient's skin after the insertion of catheter 100, only shown in figure 3b.
  • Body 1 has an inner tube which passes from one end to the other, comprising a lower section 5 that enters body 1, shown in the bottom part of the annexed drawings, which is angled at approximately 30 degrees from the vertical and constitutes a guide for catheter 100, preventing it from bending and being pulled out in the passage from the patient's body to the securing device in accordance with the invention.
  • a cylindrical head 7 with a smaller diameter than the body, at least part of which head has external threading 8 to which is fitted a cap 11, which has internal threading 12 for this purpose.
  • Cap 11 is internally hollow so as to form a housing 13 for a rubber bushing 9 which has a through central channel 10 aligned with the straight section 6 of the inner tube of body 1 and with hole 14 in the bottom of cap 11 so as to allow the passage of catheter 100 as shown in figure 3b.
  • cap 11 At the assembly stage of the device, if cap 11 is suitably screwed to body 1, rubber bushing 9 will be compressed so as to reduce the gauge of its channel 10, possibly with the aid of a washer 16 inserted between the rubber bushing and the head of body 1 to standardise the pressure exerted by cap 1 1, so as to make rubber bushing 9 adhere so tightly to catheter 100 that the said catheter is firmly secured without being constricted (figure 3b).
  • catheter 100 When catheter 100 exits from hole 14 in cap 11 as shown in figure 3b, it can be connected normally to the classic infusion systems.
  • the diameter of cap 11 does not exceed the thickness of body 1 , so as to make the device fairly compact and thus improve the patient's compliance.
  • the thread with relatively wide pitch, allows the cap to be screwed on with a small number of turns.
  • the skirt of cap 11 presents ' a plurality of vertical grooves 17 designed to aid gripping and handling.
  • the structure of the device in accordance with the invention produces improved adherence of rubber bushing 9 to catheter 100.
  • channel 10 in rubber bushing 9 will be made in various diameters, depending on the gauge of the catheter 100 used.
  • catheter securing device in accordance with the invention needs to be replaced without removing catheter 100 from the site of implantation, it is sufficient to unscrew cap 11 and gently detach adhesive base 2 in order to detach body 1 from the free catheter and insert a new securing device if required.
  • catheter 100 is removed, the securing device in accordance with the invention will be directly removed with the catheter.

Abstract

La présente invention concerne un dispositif utile pour fixer des cathéters rachidiens ou veineux qui comprend un corps (1) comprenant une base adhésive (2) prévue pour être fixée sur la peau du patient, ledit corps (1) étant doté d'un tube interne (5-6) pour le passage d'un cathéter (100), ce tube présentant une partie inclinée inférieure (5) constituant un guide d'entrée anti-constriction pour le cathéter et une partie axiale (6) qui prolonge le guide d'entrée, une tête (7) à filetage extérieur ajustée sur le corps (1), cette tête comprenant un capuchon creux vissé (11) prévu pour abriter une bague de caoutchouc (9) dotée d'un passage central (10) d'un calibre proportionnel au cathéter à fixer, ladite bague en caoutchouc étant adaptée pour bloquer le cathéter (100) en place lorsque le capuchon (11) est vissé sur ledit capuchon (11) comportant un orifice central (14) situé dans la paroi terminale, qui permet de faire sortir ledit cathéter.
