Definitions

  • the invention relates to a drainage tube for draining secretions from body and wound cavities.
  • DE-A-29 08952 describes a drainage hose in which the perforations lie in a helical groove.
  • FR-A-23 9575 it is proposed to cover the drainage hose with a flexible hose structure with a mesh-like structure.
  • DE-A-3034835 discloses a drainage hose which is formed from a support element covered with a hose-like screen covering.
  • the object of the invention is to design a drainage tube for draining secretions from body and wound cavities in such a way that the tendency to clog is further reduced and the ductility is improved.
  • the drainage hose consists of a base hose, the perforation holes of which are arranged in groove-like depressions on the outside, which is covered at least in its perforated part with a tight-fitting thin-walled cover hose, which in the Area of the perforated part of the base tube has sieve-like perforation holes.
  • the depressions covered by the thin-walled cover tube form a secretion flow bed which is separated from the surrounding body tissue.
  • the elasticity of the outer wall of the secretion bed formed by the thin-walled cover tube prevents the surrounding body tissue from being sucked up.
  • the drainage hose according to the invention can be pulled by using very low tensile forces with a significantly reduced risk of trauma.
  • a further advantage is that any clot that may have been attached to the secretion flow bed cannot be stripped off when the drainage tube is pulled, and can therefore be removed when the drain is pulled.
  • the pressure balance over the entire perforation section of the drainage hose is promoted by the secretion flow bed.
  • the basic hose of the drainage hose according to the invention is produced in a manner known per se.
  • the perforation holes are punched into the cut-out groove-like depressions in a known manner.
  • Preferred is the usual arrangement of the holes as cross perforation holes, i.e. the perforation holes are each
  • the basic hose is expediently produced from soft PVC, for example by extrusion from a correspondingly shaped nozzle. It has the usual length of a herkömm ⁇ union drainage tube, for example about 50 cm.
  • the diameter of the drainage hose moves in the frame usual for drainage hoses, for example career 9 to 21.
  • a preferred embodiment has a diameter of approximately career 12 (4 mm).
  • the diameter of the perforation holes and their mutual spacing can be varied within wide limits and correspond to the values customary for drainage hoses.
  • the groove-like depressions are preferably designed so that their cross section has no edges if possible.
  • perforation holes are only made in the part of the basic tube that is in use in the body or wound cavity, ie the intracorporeal part of the basic tube that has a length between about 5 cm and 20 cm can have.
  • the channel-like depressions can be limited to the intracorporeal part of the basic tube or preferably also extend into the part of the drainage tube that is outside of the body during use.
  • the thin-walled covering tube which is fitted tightly to the base tube, is made from the materials customary for thin-walled tube structures. It is advantageous to use materials with favorable biocompatibility, such as polyurethane (PUR) or polyvinylidene fluoride.
  • PUR polyurethane
  • a further advantage of the subject matter of the invention can be seen from this: with a very low use of the relatively expensive biocompatible material for the thin-walled covering tube, an excellent tissue-compatible drainage tube is obtained, because, as already mentioned above, the basic tube, which has no direct contact with the body tissue, is obtained the less compatible, less expensive, soft PVC can be produced.
  • Particularly advantageous is the application of the coating tube as ⁇ shrink tubing.
  • the thin-walled cover tube is expanded depending on the material in a ratio of approximately 1: 2 to 1: 4, preferably 1: 3, and then, for example, by means of a needle roller all the way to a length that corresponds to the perforation length of the basic hose, provided with a hole size of 0.5 to 1.5 mm, preferably 1 mm.
  • the heat shrinking shrinks back to its original size due to heat supplied from outside. This ensures a tight fit on the inner basic hose. A further fastening between the basic hose and the upper pull hose is not necessary.
  • Fig. 1 shows a large section of a longitudinal section through a drainage hose according to the invention.
  • FIG. 2 shows a perspective, partially broken, greatly enlarged cross-sectional view of the perforated part of a drainage hose according to the invention.
  • OMPI From Fig. 1 it can be seen how the basic hose 1 is provided in its longitudinal direction with groove-like depressions 2.
  • the perforation holes 3 are arranged in the groove-like depressions 2, in pairs, each offset by an angle of 90 °.
  • the basic hose 1 is tightly enclosed by an upper pull hose 4.

Abstract

Tuyau de drainage composé d'un tuyau de base (1), dont les perforations (3) sont situées dans des dépressions extérieures (2) en forme de conduits, recouvert au moins sur sa partie perforée d'un tuyau de revêtement (4) très ajusté, à paroi mince et possédant dans la zone de la partie perforée du tuyau de base (1) des perforations (5) en forme de crible. Il est caractérisé par une faible tendance à se boucher et par une capacité de retrait atraumatique.
