Definitions

  • a catheter In a closed suction catheter system, a catheter is maintained within a protective sleeve which is attached to a manifold which also receives the tubing of the ventilator which delivers air to the patient's lungs.
  • the catheter When suctioning is desired, the catheter is advanced through the manifold and into the artificial airway. Negative pressure is then applied to the catheter and secretions within the patient's respiratory system are evacuated.
  • the Radford system and its successors are advantageous in that they allow the patient' s ventilation to continue throughout the suctioning procedure. Additionally, they do not require the closed circuit to be broken (i.e. opened to outside air) for each suctioning procedure. It is highly desirable to have these closed suction catheter systems attached to the endotracheal tube or other artificial airway of the patient.
  • a fourth barrel 60 providing a fourth port 64 extends from the housing 14 on a side of the housing opposite the second barrel 26.
  • the fourth port 64 allows for a second catheter assembly 70 to be used with the housing 14.
  • the catheter assembly is configured to provide medical fluids directly into and from the patient's lungs.
  • a catheter 74 of the catheter assembly 70 is connected to an oxygen source 78.
  • the configuration of shown in FIG. IA is a significant improvement over the prior configurations which required the endotracheal suction catheter assembly 46 to be removed prior to use of another device.
  • the housing 14, however, has a disadvantage.
  • the adaptor body Rather than requiring instruments to bend or rotating barrels into and out of position, the adaptor body allows the clinician to align the desired proximal port with the distal port simply by manipulating the adaptor body. Such manipulation requires little additional dexterity because it is common practice for the clinician to hold the proximal end of the endotracheal tube, or the adaptor itself, when performing a procedure.
  • the adaptor body is formed as an offset wye, with the two proximal channels being axially offset approximately 30 degrees.
  • a distal port 118 which is configured for receiving the proximal end of either a T-fitting 102 or an endotracheal tube.
  • the proximal ends of endotracheal tubes are typically of a standardized exterior diameter so that devices of different manufacturers may be readily attached thereto. Thus, exact dimensions are not provided.
  • FIG. 7A shows the popoid segment 612 in its original position.
  • the first proximal channel 634 formed by the first proximal barrel 626 of the proximal portion 622 is in axial alignment with the distal channel 614 as indicated by line F-F.
  • the popoid segment 610 may be bent, however, to place the second proximal channel 642 defined by the second proximal barrel 630 into alignment with the distal channel 514. This can be accomplished by either compressing the left side of the popoid (relative to FIGs. 7A and 7B) or by extending the right side, depending on whether the popoid is expanded or compressed.
  • the popoid segment 612 will tend to hold this position until it is adjusted again.
  • FIGs. 9A through 9C are cross-sectional and partial cross-sectional views of seals which may be used to maintain positive end expiratory pressure in the flexible multiple port adaptor and prohibit foreign matter from access to the patient and to retain potentially infectious agents within the patient circuit.
  • FIG. 9A shows a duckbill closure seal, generally indicated at 774.
  • the closure seal 774 has an upper duckbill valve 776 such as are well known in the art, in combination with a disk 778 forming a PEEP seal.
  • two sealing members 776 and 778 are provided to prevent tidal volume loss because a single seal will often not completely close about the introduced device. Additionally, the second seal provides yet another barrier against patient mucus contacting the clinician.
