Definitions

  • the current invention relates to the field of medical equipment, more specifically to a tracheal or endotracheal breathing device which has an integrated system for removing secretions from a body site proximate to the endotracheal device.
  • VAP Ventilator Associated Pneumonia
  • HAI Hospital Acquired Infection
  • VAP principally affects patients who are intubated with endotracheal devices (typically in the ICU).
  • endotracheal devices typically in the ICU.
  • a flexible tube is inserted into the trachea in order to maintain an open airway.
  • Intubation is frequently performed on critically injured or critically ill patients to facilitate ventilation, including mechanical ventilation, of the lungs.
  • a balloon cuff is typically inflated just above the distal end of the tube - such that there is a tracheal/endotracheal tube segment superior to and inferior to the balloon.
  • the balloon surrounds the outer perimeter of the tracheal/endotracheal tube and when inflated it contacts the inner walls of the trachea thereby securing the tube in place and protecting the lungs from receiving undesirable material such as stomach acid.
  • the primary cause of VAP is due to the flow of infected natural secretions (mucins) from the nasal passages and the oral region into the lungs.
  • Nasal and oral secretions generally collect above the balloon in the subglottic region (superior to the balloon). If they are not appropriately drained, they can bypass the balloon and flow into the lungs.
  • mucins can dry and adhere to the trachea. Such local adhesions may be visible through a stoma port on the trachea but not through an endotracheal tube placed through the oral cavity.
  • Anecdotal reports from nurses who deal with patients in coma and on a stoma/tracheal tube have noted the problem of visible localized adhesion of the mucus to the trachea.
  • Such localized mucin adhesion is generally invisible to the caregivers (with the possible exception of what can be seen through direct stoma type tracheal ports) and pose a difficulty in locating and removal without a complete lavage. If the caked on mucins can be seen, they must be removed since they can become infected and flow back into the lungs.
  • infected mucus that drains into the lungs is invisible to the health care team and does not show itself until some type of pneumonia sets in with its associated complications.
  • infected mucins mixed with liquid can drain into the lungs and is the probable cause of Ventilator Associated Pneumonia (VAP) and must be removed from the tracheal region by the care giver.

  • Such system may reduce the incidence of infection and pneumonia and ultimately, it may reduce the incidence of death by VAP.
  • VAP ventilator associated pneumonia
  • VAP restricting fluid extraction to the area superior to the balloon is only a partial solution. It is essential to address the entire area, both superior and inferior to the balloon, to achieve a successful solution to VAP. It is only by removal or neutralization of infected mucins in the complete tracheal region and preventing the flow of these infected fluids into the lungs that VAP can be controlled.

  • the device is configured to simultaneously release antiseptic and to aspirate the mist/mucin mixture out of the trachea.
  • Each tube or channel has a first end that originates in an area that is external to a patient and a second end that terminates in an area within the trachea.
  • Each set of cooperating tubes consists of at least one inlet tube and an outlet tube.
  • the outlet tube is connected to a reservoir of antiseptic fluid or antiseptic active ingredients and a high pressure pump for creating a fine antiseptic mist.
  • the outlet tube is used to deliver antiseptic fluid to a tissue area inside of the trachea.
  • the cooperating inlet tube is connected to an aspirator for suctioning the antiseptic mist and delivering it to a canister or similar collection vessel outside of the trachea. Both cooperating tubes terminate in an area that is superior to the balloon.
  • a second set of cooperating tubes (one for delivering antiseptic fluid and one for suctioning the same) terminate in an area that is inferior to the balloon.
  • the inventive tracheal tube apparatus consists of two independent devices, a high pressure pump that can insert a pulmonary compatible antiseptic liquid and an aspirator that can provide the necessary suction to remove all the secretions that accumulate in the area superior to the balloon and that adhere to the walls of the trachea in the area inferior to the balloon.
  • the inventive device may contain a stand-alone system that is exterior to the patient and is attached to an appropriately designed endotracheal/tracheal tube. It will be externally/internally powered to provide ease of use.
  • the liquid antiseptic can only be in the form of a very fine mist that can be sprayed and simultaneously aspirated through the aspirator pump via a suction tube. Any liquids generated as the result of misting will similarly be suctioned using the aspirator pump.

  • Inflation and deflation is by means of the same port 3 shown in Figure 1. Maintaining correct balloon pressure is necessary to restrict contaminated liquid from flowing around the balloon and into the lungs. (Typically the balloon pressure is maintained and periodically checked. In the Pump/Aspirator device a controller will automatically check the balloon pressure and make sure that the seal between the tracheal wall and the balloon is consistent.)
  • Port 4 and Port 5 will be used to run the wires to the tip of the flexible tracheal tube thus providing directional control of the tip to the caregiver. In normal operation the wires will be pre-adjusted to direct tip toward the center of the trachea in the direction of the lungs.

Synchronizing the action of aspirator 17 and pump 18 with the mechanical ventilator is important. The spraying of the aerosol mist from nozzle 8b must coincide with the expulsion of air from the lungs through lumen 1. This activity will be sequenced using the electronic controller 16.

  • the controller also receives input via a mechanical or electrical signal from the ventilator (not shown) that will allow controlled delivery of atomized antiseptic mist via nozzle 8b into inferior region 13b. In this manner, the controller is programmed to sequence the operation of all components of the device for injection of antiseptic and retrieval mucus and other liquid and mist from the tracheal area. In the case where a tracheal tube is connected to an external ventilator, the controller also will time the release of any mist to occur during a period that the ventilator is applying negative pressure to the patient's lung.
  • Valves 19 and 22 will control the fluid injection and removal from the area superior to the balloon. Valve 19 from aspirator 17 and valve 21 from pump 18 will be interlinked so that they will operate in conjunction. This will assure that any fluid that is used for the lavage, mucin removal and/or the by-product of oral hygiene will be removed appropriately. Aspirator 17 will dispose any collected fluid into container 15.
  • Valve 21 will be used for aerosol spray into the region inferior to the balloon. It should be noted that pump 18 will have the required power to completely atomize any antiseptic fluid withdrawn from container 14 and moved through port 8 to the nozzle 8b. The aspirator 17 controlled by valve 20 will be activated prior to operation of pump 18 such that suction will begin prior to mist injection in order to assure full removal of any liquefied secretions. It will be understood by those of ordinary skill in the art that various means of creating a mist are possible in different embodiments of the invention. For example, as an alternative to an aerosol spray - antiseptic fluid may be vaporized and delivered in gas phase. In other embodiments, fine droplets of antiseptic is delivered through micro pores at the terminal end of channel 6 or 8.
