DESCRIPTION:
BRIEF SUMMARY
Device for attaching a flexible tube to a pierceable material, in particular a drain to a patient's skin.
The present invention relates to a device for attaching a flexible tube to a pierceable material from which it protrudes, said device having an application in various fields such as horticulture or surgery.
In horticulture, for example, the immobilizing of small watering hoses, called sprinklers, installed on a main hose which is made of rubber and acts as a feed hose, is not satisfactory: the sprinkler is introduced by force into an orifice which is of a diameter smaller than its own and which is formed in the wall of the feed hose, and the connection is ensured only by the compression action exerted by the feed hose on the sprinkler which has been introduced. Consequently, the sprinkler can easily been torn out by accidental pulling.
In surgery it is common practice to position one or more drains in the operation site at the end of a surgical intervention, which drains are intended to remove body fluids and protrude from the body either from intact skin or at the edge of the surgical wound. These drains are removed only after several days of convalescence on the part of the patient, and it is important that they should be immobilized well and that their presence should not lead to any irritation or infection.
The immobilizing technique generally performed consists in tying a suture thread on the drain and fixing the thread to the patient's skin by means of a stitch.
This procedure has its disadvantages: chain which does not prohibit the drain from sliding a few millimeters, with the result that it moves back and forth in the skin or the wound, with an obvious risk of infection; happen that the thread, if insufficiently tight, will slide along the drain, thus aggravating the disadvantage analyzed hereinabove; requires a certain amount of time, and any time saving, however small, in routine procedures is important for efficient management of the operating team.
There is therefore a need for a device which would make it possible to attach a flexible tube, such as a drain or a drip, safely and quickly to a pierceable material such as a patient's skin or another flexible tube, respectively, while preventing any relative movement between them.
This aim is achieved by means of the invention in the sense that it provides an attachment device which consists of a metal component capable of being converted, by bending it about a plane, called the "bending" plane, from an "open" configuration before use to a "closed" configuration during use, said component exhibiting a cutout having an access which opens out on one of the edges of the component, said cutout being adapted to receive said tube in the vicinity of the point where it protrudes from said material, said bending plane being median with respect to said cutout and passing through said access, the component exhibiting first and second attachment means which are inactive when said component is in the open configuration and come into engagement with said tube and said pierceable material, respectively, when the component is converted, by bending, to the closed configuration.
In practice, said first attachment means consist of projections provided on opposite edges of the cutout, and these projections exhibit a lead edge adapted to pinch slightly into the wall of the tube (16) upon bending. The geometry of the projections is such that, after bending, said lead edges are perpendicular to the axis of the tube. This ensures a symmetrical longitudinal immobilization of the tube able to withstand the tensile or compressive stresses to which the tube may be subjected.
The second attachment means consist, for their part, of at least one pair of oblique claws, the points of which converge toward a line belonging to said bending plane, and the claws preferably have a length which is such that, after bending, their point intersects the bending plane, so that the points of a given pair of claws cross each other. If appropriate, it is possible to provide for one of the
