Definitions

  • This invention relates to capping devices associated 5 with endotracheal tube connectors.
  • Bronchoscopy involves the insertion of a thin instrument
  • a bronchoscope into a patient's airways for visual inspection of the patient's lung and bronchial passages. If access is not provided for in the ventilation system, the patient must be disconnected from the ventilator prior to insertion of the bronchoscope.
  • U.S. Patent No. 4,416,273 to Grimes shows a cap valve assembly which has a cap that allows for the admission of a thin tubular instrument while keeping sealed the end of the connector through which the instrument is inserted.
  • the Grimes cap suffers from the disadvantage that the only way to fully open the connector is to completely disconnect the cap from the connector, thereby risking loss of the cap.
  • U.S. Patent No. 4,580,556- to Kondur discloses a plugged connector cap wherein both the plug and the cap are 'independently tied to the connector by cords. While the cap cord of Kondur permits removal of the cap from its connector opening without disconnecting the cap from the connector, the cord can not be easily removed from the connector if it is desired to completely disconnect the cap from the connector, such as to replace the cap.
  • the present invention provides a capping device for covering the mouth of an access port of a conduit connector and a combination of such a capping device with a conduit connector.
  • the capping device includes a cap having a downwardly extending skirt and an access opening through which a bronchoscope, catheter or other small diameter medical device may be inserted.
  • the skirt includes an inwardly extending rim around its internal surface which detachably snaps over a lip around the mouth of the port.
  • the access opening is selectively sealable by a complementary plug that is tethered to the cap by a flexible tether strap.
  • the capping device further includes a flexible anchor strap extending from the cap which snaps onto a knob on the conduit connector, thereby retaining the cap on the connector when not covering the mouth of the access port.
  • a flexible anchor strap extending from the cap which snaps onto a knob on the conduit connector, thereby retaining the cap on the connector when not covering the mouth of the access port.
  • Figure ' 3 is a cross sectional view taken along line 3-3 of Figure 2.
  • a capping device 10 which includes a cap 12 and a plug 22 tethered to the cap 12 by a tether strap 24.
  • the cap 12 includes a cover portion 14 which extends toward the center of the cap, leaving an access opening 20 which is sized to provide a substantially airtight fit with the body of examining instruments such as bronchoscope • (not shown).
  • a continuous skirt 16 extends downwardly from the cover portion 14.
  • the capping device 10 is made in one piece of a soft elastomeric material, such as silicone rubber or thermoplastic elastomer.
  • a connector 40 which is shown as being generally T- shaped, has three inlets 42, 52 and 54 to a common passageway within connector 40.
  • An access port 50 provides access to inlet 42 via mouth 58, over which the cap 12 is snap-engaged. The cap is snapped in place on the connector 40 by the engagement of a first interior rim 18 over a lip 44 around the mouth 58 of the access port 50, to form a sealing fit.
  • a second rim 30, parallel to the first rim 18, may be provided on the cap 12 to improve sealing of cap 12 over access port 50.
  • the connector 40 has a knob 48 conveniently located adjacent the connector mouth 58, as shown in Figure 1.
  • the capping device 10 also has an anchor strap 26 which extends from the cap 12.
  • the anchor strap 26 has a keeper opening 28 which is snapped over the knob 48 on the connector 40 to anchor the capping device 10 to the connector 40 when not covering the access port 50.
  • knob 48 extends outwardly of access port 50 by means to a neck 56.
  • the diameter of the keeper opening 28 is smaller than the diameter of the knob 48.
  • the anchor strap 26 is retained on the neck 56 after it is snapped over the knob 48.
  • the neck 56 allows the cap 12 to be easily rotated out the way of mouth 58 for performing a medical procedure through mouth 58.
  • the width of the anchor strap 26 is greater than the width of the tether strap 24, thereby making the anchor strap less flexible and less subject to twisting than the tether strap. This facilitates rotation of anchor strap 26 about neck 56.
  • the anchor strap 26 is made shorter than the tether strap 24 in the embodiment shown, thereby preventing the capping device 10 from flopping about while it is anchored to the connector 40 by anchor strap 26 alone.
  • a pull tab 34 may be provided on the plug 22 to allow the plug 22 to be more easily removed from the access opening 20.
  • the connector shown in this embodiment is a rectangular, generally T-shaped connector, it is understood that other types of connectors, such as Y-shaped connectors, may also be used with the capping device of the present invention.
  • an examining instrument such as a bronchoscope (not shown) into the patient's airways for visual examination thereof.
  • a patient on mechanical ventilation may require frequent suctioning through a suction catheter (not shown) to maintain proper bronchial hygiene.
  • Both the bronchoscope and catheter are long, slender, tubular devices that may be inserted through the endotracheal tube connector and endotracheal tube when in place.
  • a bronchoscope, catheter or other slender instrument of suitable diameter may be inserted through the access opening 20 of the cap 12.
  • the access opening 20 is about 3 to 4 mm (.14 to .15 in) in diameter and the resilience of the cap 12 allows the opening 20 to stretch to accomodate instruments up to about 8 mm in diameter.
  • the cover portion 14 squeezes about the inserted instrument, sealing the access port 50 against loss of tidal volume.
  • the present invention th ⁇ s maintains positive system pressure while a suitably sized bronchoscope or catheter is present within access opening 20 of cap 12. After the instrument is removed, the plug 22 may be quickly inserted into access opening 20 of cap 12 to reseal the opening.
  • the cap 12 may be released from its position sealing the mouth 58 of access port 50. Because the cap 12 is flexible, it is readily released by unsnapping the skirt 16 from its position over the lip 44 of the access port 50. Once the cap 12 is disengaged from lip 44, a large diameter suctioning catheter or other instrument may be inserted directly through mouth 58 and inlet 42 of access port 50. Because the capping device 10 remains attached to the connector 40 by the anchor strap 26, the capping device 10 is retained just out of the way of the procedure being performed so that it may be quickly replaced over the mouth 58 at the end of the procedure by snapping the skirt 16 over the lip 44 of the access port 50. Also, the capping device 10 can be completely snap-disengaged from the connector 40, if desired, such as for cap replacement. This can be carried out without disassembly of the ventilation tubing, as is required with some prior art devices.
  • a present invention provides a convenient-to-use capping device for covering a conduit connector mouth of a ventilating device.
  • the capping device of the invention permits selective access through a selectively plugged access port for complementarily sized instruments.
  • the cap can be snapped-disengaged from the mouth of the conduit connector and rotated completely out of the way of the conduit mouth, while remaining anchored to the conduit connector by a separately snap-engageable anchor strap.
