Definitions

  • the snap arrangement includes an oblong shaped opening into the proximal end of the outer tube, a flange on the proximal end of the inner tube, a collar formed on the inner tube near its proximal end, and a ring groove of enlarged diameter formed in the inside surface of the proximal portion of the outer tube.
  • the present invention relates to the field of surgical appliances, and more particularly, to tracheal tube assemblies and the like.
  • Tracheal tubes are utilized in situations wherein the normal respiratory functions of the nose or throat have been impaired. It is quite common, in the event of such an occurence, for the use of a surgical procedure termed tracheotomy; that is, for an incision to be made in the throat and a tracheal tube assembly inserted through the opening and into the trachea. This procedure allows communication between the trachea, or windpipe, and the ambient air so that the impaired areas of the nose or throat are bypassed in the respiratory function.
  • tracheal devices Various types have heretofore been used for this purpose.
  • Most recently the most common type of device for providing passage to the trachea has been a metallic tube which is either of solid silver or silver plated material.
  • Devices of this type are generally rigid, having a predetermined curvature, and have a flange or flanges at their outermost ends which are designed to be flush against the exterior surface of the throat.
  • An obturator has been provided to close the tube during insertion.
  • the primary object of the present invention is to provide an improved tracheotomy tube structure which will be free from the aforementioned and other disadvantages of prior devices of this type.
  • Another object is to provide an improved tracheotomy tube structure which affords freedom of motion of the wearers head and neck, and which is inert to the human body.
  • a tracheotomy tube structure made of silicone rubber. Silicone rubber is inert to the human body. Provision is made for an inner tube and an outer tube as is conventional in such devices, but both tubes are by the nature of the silicone rubber so flexible that any one shape will bend to fit a number of different curvatures and the head and neck movements of the wearer are virtually unrestricted. Since the material is soft and inexpensive, compared to many prior art materials, the ends of the tubes may be cut to the desired length before insertion and the excess discarded. The two tubes are connected in use by an easily releasable snap arrangement and the device may also be molded to form a releasable seal between the inner and outer tubes.
  • an obturator of the same material which is also flexible and easily cut to the desired length. If desired, the device may be tinted to match the wearers skin color.
  • a further advantage is the nonwettable nature of silicones which helps to prevent clogging of the tube by mucous.
  • FIG. 1 is a view in perspective showing the tracheotomy tube assembly of the present invention in place on the throat of a patient;
  • FIG. 2 is a side view in elevation of the inner tube of the device shown in FIG. 1;
  • FIG. 3 is a side view in elevation of the outer tube of the device shown in FIG. 1;
  • FIG. 4 is an end view in elevation of the outer tube shown in FIG. 3;
  • FIG. 5 is a fragmentary view, partly in cross-section, showing the manner in which the inner tube is withdrawn from the outer tube;
  • FIG. 6 is a fragmentary view, partly in cross-section, of the outermost portions of the inner and outer tubes, the inner tube being in a position slightly withdrawn from its normal operational position;
  • FIG. 7 is a side elevational view, partly in cross-section of an obturator made in accordance with the present invention in position for inserting the outer tube into the trachea of a patient.
  • FIG. 1 a tracheal tube assembly
  • an outer tube 11 of silicone rubber material which is inserted into an incision through the patients throat and into the trachea.
  • the tube 11 may be secured in place by means of a neckband connected to a flange 12, which is formed on the outermost proximal portion of the tube 11 (as may be seen in greater detail in FIG. 3) and is adapted to rest against the throat.
  • an inner tube 13 sometimes known as a cleanout tube and also made from silicone rubber, is provided for insertion into the outer tube 11.
  • the inner tube 13 has an outer diameter which is slightly less than the internal diameter of the outer tube 11 and has provided on its outermost end a flange or gripping portion 14.
  • a ring groove 16 of enlarged diameter is formed in the inside surface of the proximal portion of the outer tube 11 and is adapted to be engaged by a collar 17 which is formed on the inner tube 13 in a corresponding position.
  • the outer opening 18 into the outer tube 11 is preferably formed in an oblong configuration with one diameter which is substantially the same as the enlarged diameter of the ring groove 16, while the diameter of the opening 18 which is perpendicular to the diameter which was first considered is made considerably smaller, so that it will engage the outermost surfaces of the collar 17 of the inner tube 13.
  • FIGS. 5 and 6 A consideration of FIGS. 5 and 6 will show the reasons for providing the opening 18 with an oblong shape.
  • the inner tube 13 is designed for removal and cleaning while the outer tube 11, once inserted into a patient, remains in place.
  • the collar 17 on the inner tube being resilient, slides through the opening 18 and snaps into the larger diameter ring groove portion 16 formed in the inner surface of the outer tube.
  • the partially circumferential flanges which form the smaller dimension of the opening 18 serve to hold the inner tube in place and in sealing relationship with the ring groove 16 by bearing against the outer portions of the collar 17.
  • the flanged gripping portion 14 is squeezed between thumb and finger as shown in FIG.
  • an obturator of solid silicone rubber for insertion of the outer tube 11 after the incision has been made.
  • the obturator comprises a solid flexible rod 19 to which there are attached a handle or knob 21, and a collar 22, which prevents the obturator from being inserted too far into the tube.
  • the obturator is of a slightly smaller diameter than the inner diameter of the outer tube and serves to facilitate introduction of the tube into its proper place without blockage.
  • Each of the tubes 11 and 13 and the rod 19 of the obturator are of flexible silicone rubber material and have a preset curvature and length corresponding to the curvature and length required for the usual patient. By virtue of the flexibility of the material the device will bend during insertion to conform to the actual curvature needed. If a shorter tube is indicated, the tubes and obturator may be shortened before insertion by cutting the distal ends to the desired length, thus eliminating the necessity of stocking a large variety of shapes and sizes.
  • the material of the device may be tinted to flesh tones in order to make it less noticeable.
  • a tracheal device comprising:
  • a flexible outer tube having predetermined curvature and adapted to be inserted into the trachea of the user through an incision in the throat
  • a flexible inner tube having an external diameter slightly smaller than the internal diameter of the outer tube and being freely insertable into the outer tube;
  • the outer tube including a transversely extending flange at its proximal end, which flange is adapted to bear against the skin of the user around the incision,
  • the outer tube including further a ring groove located near its proximal end opening, the diameter of that ring groove being larger than the inside diameter of that tube,
  • said inner tube including a flexible collar of enlarged diameter on its outer surface located to mate with the ring grooveof the outer tube, when the inner tube is inserted its maximum distance into the outer tube,
  • the outer tube including further an oblong configuration forming the proximal end opening into that tube, which oblong configuration has a first diameter substantially the same as the enlarged diameter of the ring groove, and a second diameter, perpendicular to the first, considerably smaller than the enlarged diameter of the ring groove, and adapted to hold the collar of the inner tube in place in the ring groove, and
  • the inner tube including further a transversely extending flange at its proximal extremity, which flange is flexible and manually grippable and located in close proximity to the flexible collar and which flange when squeezed in a predetermined direction contracts the collar and permits withdrawal of the inner tube from the outer tube.
  • both the inner and outer tubes are made of silicone rubber.
