Definitions

  • respiration air during the inhalation phase closes the two-way valve and applies pressure to the outside of the bladder at the downstream end to maintain the seal, whereas, during exhalation, the absence of the respiration air pressure allows the two-way valve to open to enable the lower pressure air to provide suflicient inflation of the bladder for sealing purposes.
  • This invention relates to respiratory catheters of the type consisting of a tube for introducing air to the lungs of the patient, adapted to be introduced in the trachea of the patient and provided with a tube surrounding bladder to create a tightening in relation to the wall of the trachea, whereby the interior of said bladder is in connection with a separate pipe connected to a source of pressure.
  • the aim of the present invention is to provide a respiratory catheter applicable to artificial respiration without such disadvantages as found in prior art respiratory catheters. It is an object of the present invention to provide means with which to obtain an airtight closure of the trachea during both the inspiratory and expiratory phase of artificial ventilation of the lungs without subjecting the mucosa of the trachea to pressures harmful ice thereto.
  • a respiratory catheter tube which is provided With a bladder comprised of a thin, preferably nonresilient foil material with such dimensions that it can readily be brought into tightening abutment against the wall of the trachea without resilient deformation of the bladder, and which communicates With a compressed air source through a two-Way blocking valve disposed in the pipe through which respiration air is supplied to the catheter tube, said blocking valve being controlled by the pressure of the respiration air.
  • a respiratory catheter consisting of a catheter tube 1, which at one or its upper end is joined to a T-shaped tube 2, one branch of which is closed olf as by a cork 3, the main branch 4 of the tube serving as inlet nozzle for the respiration air to the catheter tube 1.
  • the opposite or lower end of the catheter tube is provided with an appropriate bent segment and has a bladder 5 secured on the outside of said tube around said bent segment.
  • the bladder may be supplied with air under pressure through a duct 6 in the wall of the tube 1.
  • a thin pipeline 7 leads into the main branch 4 of T-shaped tube 2 and is connected to one end of an inflatable-collapsible blocking valve 8 disposed in said main branch 4 as shown.
  • the blocking valve 8 may comprise two plane foil members 8 welded together along their rims to thus form a hollow inflatable-collapsible valve.
  • a thin pipe 9 is connected with the other end of the blocking valve and in turn outlets from the tube branch 4 to serve as an inlet nozzle for delivering compressed air to the bladder 5 from a source separate from that supplying the respiratory air.
  • the respiration air pressure applied is of course dependent on the patient and on varying external circumstances and should normally be of a pressure height corresponding to 20-70 cm. column of water, whereas, the air pressure in the bladder 5 may be maintained somewhat lower, eg at a height corresponding to 16-20 cm. column of water.
  • a pressure like that cannot injure the mucous membranes of the trachea and the increase of pressure caused by the respiration pressure does not exceed the pressure imposed on the rest of the air passage by the respiratory treatment.
  • the catheter of the present invention When using the catheter of the present invention, practically no force is required for pressing the bladder 5 against the trachea wall and the pressure exerted within the bladder is consequently entirely utilized to provide sealing. Moreover, the bladder tends, without alterations of the internal pressure, to comply with any alteration of the dimensions of the trachea still without requesting a particular pressure application; thus it is possible to maintain pressure in the bladder at the lowest possible level.
  • a performance is achieved where the amount of air pressure introduced into the bladder 5 through duct 6 from a separate source of compressed air at a lower pressure than the respiration air so as to fill and enlarge said bladder, such air is confined in said bladder as soon as the respiration air under pressure being delivered through tube 1 rises.
  • the respiration air pressure closes blocking valve 8 preventing entry or outflow of the air under lower pressure from bladder 5, with the respiration air itself exerting a pressure against the outside of the bladder at the lower part, i.e., facing the lungs causing an increase of the abutting pressure of the bladder against the trachea.
  • blocking valve 8 is located in branch 4 so as to provide an eflective control of the valve. This allows for a utilization of the drop of pressure which occurs in the course of the passage of the air between the entry orifice of the respiration tube 1 and the valve 8.
  • an opening of the valve 8 will occur which allows a part of the volume of air in the bladder and which was compressed therein by the externably located maximal respiration pressure, to escape, whereby the pressure in the bladder for a short moment becomes too low to keep up a perfect sealing of the trachea against the respiration pressure not yet dropped to its minimum value.
  • a respiratory catheter comprising a tube adapted to be introduced into the trachea of a patient for delivery of respiration air under pressure to the patients lungs,
  • said tube having an upper entry end anda lower bent section, a bladder of thin, non-resilient material enclosing the bent section of said tube and being secured thereto, said tube having a duct therein communicating with the interior of said bladder, an elongated in-flatablecollapsible blocking valve disposed in said tube at the entry end thereof, a pipe line connecting one end of said blocking valve with said duct, and a pipe connecting the opposite end of said blocking valve with a source of air at a pressure lower than that of the respiration air, the pressure of respiration air flowing through said tube during inspiration collapsing said blocking valve to isolate said bladder from the source of air at pressure lower than that of said respiration air whereby the respiration air flowing to the patients lungs exerts a pressure on the outside of said bladder at the end nearest the lugs to thereby force said bladder into tightening engagement with said trachea, said blocking valve becoming inflated during expiration when the pressure of said respiration air is released whereby said air at a pressure lower than that of said respiration
  • the respiratory catheter of claim 1 further comprising a T-shaped fitting on the entry end of said tube, said fitting having one branch received in said tube, another branch closed off with a plug, and a third branch serving as an inlet for respiration air, said blocking valve being disposed in said third branch.
