  • Patent number: 7878202
    Abstract: A respiratory suction catheter assembly includes a manifold supporting a rotatable swivel member for engagement with an endotracheal tube, and a seal support body disposed on a boss of the manifold opposite the part supporting the swivel for supporting a catheter tube seal and a porous filter for filtering air flowing into and out of a flexible elongated sheath enclosing the catheter tube. The sheath includes opposed tapered ends secured to the seal support body and to a boss on a suction control valve housing. The valve housing supports a tapered plug closure member engageable with a resilient actuator and a slide-lock member. Certain components, including the sheath, the seal support body, the filter, the catheter tube seal and the catheter tube may be treated with an anti-microbial agent.

  • Patent number: 7775206
    Abstract: A suction catheter assembly, particularly adapted for neonatal use includes a distal manifold body including a rotatable connector for connection to an endotracheal tube, a ventilating port member and an ancillary catheter receiving port member. The manifold body is rotatably joined to a catheter tube seal housing. The seal housing includes an irrigation port member. A catheter tube wiper seal and a filter member are disposed in the seal housing which is joined to a suction control valve assembly by an elongated flexible sheath defining an enclosed space through which the catheter tube extends between the valve assembly and the manifold. A resilient closure member actuator and slide lock member are engageable with a closure member of the valve assembly.

  • Patent number: 6165625
    Abstract: Improved instrument pad surgical drape for use during surgical procedures is disclosed which is resistant to melting caused by high intensity light generated from sources such as fiberoptic illumination systems. The instrument pad and drape comprise an infrared energy reflective film/foam laminate that may also have a high coefficient of friction which is useful for retaining surgical instruments in place and preventing them from slipping off the pad during a surgical procedure.

  • Patent number: 5975082
    Abstract: A tear-away surgical drape is provided by the present invention. The drape has a fluid absorbent pad attached to the upper surface of an underlying base sheet. The drape has an opening, or fenestration, therein through which the operation is to be performed. The absorbent pad has a score line in it which extends from an edge of the pad to the fenestration so that it, like the tear-away material forming the base sheet, may be easily torn away after surgery. The present drape is particularly useful when it is necessary to leave a tube, catheter, or other apparatus attached o the patient after the surgery. The tear-away aspects of the drape allow it to be removed without disturbing the attached apparatus.

  • Patent number: 5074316
    Abstract: A surgical drape for use in surgical procedures such as those wherein a catheter is inserted within a vein or artery of a patient. The drape includes a base sheet, for covering portions of the patient, that includes a fenestration and at least one tab portion that provides a member to which a catheter, inserted in a vein or artery of a patient, can be removably coupled during the surgical procedure. The drape further includes a pleated sheet portion so constructed and arranged so as to drape along the patient's arm near the operative site. In an embodiment, the drape includes an instrument pouch. The instrument pouch can be removably secured to the drape near the operative site. The pouch includes means for removably receiving surgical tools and positioning catheters used during the surgical procedure with respect to the drape. Preferably, the pouch is substantially transparent.
