Definitions

  • ABSTRACT A bandage for laryngotomy patients comprises an air inlet portion having an outer fibrous layer consisting of a fibrous material designed and dimensioned to collect particles and bacteria without forming a substantial resistance to the flow of air inhaled therethrough, said inlet portion including an intermediate portion designed and mounted to permit a large surface contact with the inhaled air and made from a material having heat and moisture exchanging properties so that it receives heat and permits condensation of moisture from the expired air and transfers the received heat and moisture to the inhaled air.
  • Said intermediate portion includes further an inner layer with an attachment means shaped to be placed into sealing engagement with the throat of the patient around the stoma and comprising a net located opposite the intermediate portion and of a relatively large width of the meshes and a stiffness suitable to protect the intermediate portion from deformation and preventing also its being sucked in by breathing.
  • the present invention relates to a bandage for laryngotomy patients.
  • it has been necessary to open the trachea in an operational manner in order to allow the 'patient to get a sufficient amount of air.
  • many problems developed with these patients due to the drying of the mucous membranes in the air pipes, and in connection therewith, a substantially increased sensitivity to infections also occurred.
  • the reason for the troubles mentioned above is that by the trachoetomy (the cutting of the trachea), the function of the nose is substituted, i.e. moisturizing, heating and, to some extent, filtering of the inhaled air cease.
  • this apparatus comprises a tightly sealed metal foil which receives the moisture and, to some extent, also the heat of the expired air, and returns them to the respiratory system in connection with the expiration.
  • the heat and moisture exchanger mentioned above is attached to a so-called tracheal cannula that is always used in tracheotomy.
  • Tracheotomy is usually a tempo rary action. Most often after a relatively short period of time the patient may breathe without tracheostoma and the tracheotomy is discontinued, i.e. the hole in the throat is permitted to heal.
  • laryngotomy In some patients it is necessary, due to a serious illness in the larynx or in the vicinity thereof, to remove the larynx and the upper part of the trachea by a so- ;called laryngotomy. These patients are also provided Swith a tracheostoma and must breathe through this for the rest of their lives.
  • the hitherto used protection comprised a multi-layered gauze dressing hanging loosely in front of the stoma on a string around the neck.
  • the dressing mentioned above was soaked with ordinary water at different intervals.
  • the patient himself has made completions to the dressing or bandage for personal use, such as by stabilizing it with coarse plastic nets.
  • Some patients have had perforated silver shields, etc, made for them.
  • the purpose of the present invention is to provide a bandage that prevents the patient from inhaling air that is cold and dry, permits the filtration of the particles, and eliminates the risk that the bandage or portions thereof can be sucked into the stoma by inhaling.
  • FIG. 1 shows the bandage according to the invention cut through the center
  • FIG. 2 shows an alternative embodiment of the bandage cut through the center
  • FIG. 3 is a front view showing the bandage of FIG. 1 applied in an operative position to the throat of the patient
  • FIG. 4 is a front view showing the bandage of FIG. 2 applied in an operative position-to the throat of the patient, and
  • FIG. 5 is a side view of the bandage of FIG. 2 applied to the throat of the patient.
  • the bandage according to the invention is to be applied to the throat of the patient so that the bandage sealingly engages around the stoma of the patient, meaning that the inhaled and expired air is made to pass through the bandage.
  • the bandage comprises three main portions, i.e. an outer fibrous layer 1, an intermediate portion 2 and an attaching means 3.
  • the outer fibrous layer comprises a fibrous cloth having a predetermined thickness and density.
  • a fibrous cloth suitable for this purpose is commercially called a non-woven tissue.
  • the fibrous layer may in itself comprise two outer layers having the fiber orientations disposed in opposite directions and an intermediate portion of a pile material.
  • the fibrous layer 1 engages the intermediate portion 2, which is designed and located to permit a large surface contact with the air flowing therethrough, to receive heat and condense the moisture from the expired air and to transfer the received heat and moisture to the inhaled air.
  • the intermediate portion 2 is made from a so-called corrugated mini cardboard which is rolled to a helical shape to define a cylindrical element which has a height of l1.5 cm.
  • corrugated cardboard it is suitable to use a cellulosic, metallic or plastic element which is designed to permit a large surface contact with the air flowing therethrough.
  • an attachment means 3 engages the side of the intermediate portion 2 opposite the fibrous layer 1, and may be designed for different applications to attach the bandage to the throat of the patient.
  • the attachment means 3 comprises a plastic foil 3a to engage the skin of the patient, this plastic foil 3a is soft and flexible so that it permits a certain movement in the skin lying therebelow and also prevents abrasion from occurring below or around the bandage.
  • a suitable plastic foil is commercially sold under the name Lencoflex occlusive.”
  • the plastic foil 3a is provided with a hole, and a net 3b is attached thereto and covers the hole.
  • This net 3b is made from a material comprising a synthetic fiber and has, preferably, the width of the meshes of 1-3 mm.
  • the intermediate portion 2 is kept in position between the outer fibrous layer 1 and the plastic foil 30 by attaching the outer fibrous layer and the plastic foil to each other around the intermediate portion.
  • the outer fibrous layer 1 integrates with the plastic foil 3a at a distance from the jacket surface of the intermediate portion so that a space is defined be tween the jacket surface, the outer fibrous layer 1 and the plastic foil 3a.
  • An annular cushion 4 made from a plastic foam or similar material is provided in this space.
  • the bandage described above is to be attached directly to the throat of the patient by bonding. This is accomplished by providing the plastic foil 30 with a skin sensitive adhesive, whereupon the bandage is pressed onto the throat so that the adhesive adheres around the stoma and the net 3b is positioned opposite the stoma. This means that the breathing air is completely caused to flow through the bandage so that the inhaled air is filtered, heated and moisturized at the same time as the outer fibrous layer 1 exteriorly protects the intermediate portion 2 and the net prevents the intermediate portion from being deformed, broken and/or inhaled.
  • the described bandage is suitable for use at night when the need to suck is minimal, but also during the day for most patients, that is patients who do not have to suck or blow their noses several times a day.
  • the bandage according to the invention comprises a shield 5 onto which the plastic foil 3a is attached.
  • This shield is made from a plastic material which is sturdy and elastic, such as PVC or nylon, and preferably the plastic material is so selected that it permits a certain degree of flexibility by heating to a temperature exceeding 37C.
  • the plastic shield 5 has a hole and the intermediate portion 2 of the bandage projects into this hole when the plastic foil 3a has been attached to the shield by means of an adhesive or the like.
  • an annular cushion 6 is mounted to the shield and surrounds the hole of the intermediate portion 2.
  • This cushion comprises a core 6a of a plastic foam or rubber foam and a cover 6b of a material gentle to the skin.
  • the cushion 6 may be made from a thin plastic foil filled with a gas, preferably air, which has a low pressure to define a so-called low pressure cushion.
  • the shield In order to apply the shield 5 to the throat of the patient, the shield is provided with two extended holes 5a, to anchor a rubber band 7 or the like placed around the neck of the patient.
  • This rubber band 7 may be applied to the shield by tying end hooks thereof over the edges of the holes 5a.
  • the shield may be so designed and the rubber band applied in such a manner that the shield, by a lever action, obtains an advantageous engagement with the throat.
  • the shield has a somewhat tapering shape so that the narrower portion may be made to project to some extent between the collar bone of the patient.
  • the hole for the intermediate portion is displaced in relation to the center of the shield so that it is positioned substantially in the narrower part of the shield.
  • the holes 5a for the band 7 are provided on the opposite side of the shield center in the wider part thereof and adjacent two side edges engaging each other.
  • the foil In order to make the foil 3a so as to permit direct application to the throat and to make it project downwardly between the collar bones of the patient and also permit its attachment to the shield 5 free from contact with the holes 5a, the foil suitably has a tapering shape.
  • a bandage for laryngotomy patients who have a tracheostoma, having an air inlet portion comprising:
  • said intermediate portion comprising a material having heat and moisture exchanging properties whereby heat and moisture are transferred from exhaled air to inhaled air passing therethrough,
  • said inner layer comprising means for sealing said bandage in engagement with the patients throat around the stoma so that all breathing air is caused to flow through said bandage
  • said inner layer comprising separating means for preventing the sucking in of any portion of the bandage by the patient.
  • said intermediate portion is cylindrical in shape
  • said outer and inner layers are attached to each other at a point spaced apart from said jacket, and
  • a ring of elastically yieldable material is placed in the space between said jacket and said layers.
  • said inner layer comprises a foil having a hole therein for adhesive application to the patients throat, and
  • said separating means is mounted onto said foil covering the hole.
  • said inner layer comprises a foil and a shield, said foil being attached to said shield by a binder,
  • said shield has an annular cushion mounted thereon, said cushion being of a height such as to engage the throat of the patient around the stoma when said bandage is applied, and
  • said band is inserted through two holes in said shield
  • said foil has a tapering shape so that it is free from engagement with the holes for said band when used and so that alternatively it may be directly applied to the throat of the patient with the tapering portion thereof projecting between the collar bones of the patient.
  • the holes provided in said shield for said band are located above the center of said shield and adjacent two opposite edges thereof,
  • said band is mounted over the portions of said shield between said holes for said band and the outer edge closest thereto and under the portion of said shield between said holes for said band, whereby lever action is applied to said shield.
  • a bandage according to claim 7, wherein the shield is made of a plastic material having relatively low flexibility properties and may permit some deformation if subjected to a temperature in excess of 37C.
