Closed catheter suction system
First Claim
1. A catheter suction system comprising:
- a catheter having a proximal end and a distal end, said catheter defining a lumen therethrough which communicates with a tip formed at said distal end of said catheter;
an adapter assembly slidably engageable with said distal end of said catheter, said adapter assembly comprising a rinse chamber isolated from a ventilation circuit; and
a suction control valve secured to said proximal end of said catheter and in communication with a vacuum source;
wherein when said tip is disposed within said rinse chamber a rinse solution is then instilled into said rinse chamber; and
when said suction control valve is activated, the rinse solution is aspirated through said tip and said lumen and into the vacuum source to cleanse said catheter without interrupting the ventilation circuit.

Abstract
The present invention relates to closed catheter suction systems used to aspirate secretions from the trachea of a patient and to rinse the catheter after such aspiration. The apparatus comprises a flexible suction catheter encased within a sheath that is fixed to a vacuum source at its proximal end and extendable through an adapter assembly at its distal end, near the patient. The adapter assembly connects the closed catheter suction system to a patient connector, and a suction control valve at the proximal end operates to aspirate secretions and to rinse the catheter. The closed catheter suction system also includes a lavage port and a rinse port, the latter of which is positioned near the distal end and is isolated from the ventilation circuit through the innovative use of a rinse chamber and a one-way valve. Advantageously, the lavage port is positioned near the proximal end, away from the patient, so as to prevent the accidental leakage of lavage into the ventilation circuit. Further, both the lavage port and the rinse port include a self-closing fill-valve that prevents the accidental loss of ventilator volume and which also prevents the discharge of infectious pathogens to the surrounding environment throughout the aspiration and rinse procedures.

24. A method for rinsing a catheter suction system without interrupting a ventilation circuit, said method comprising the steps of:
-
(a) providing a catheter suction system comprising;
a catheter having a proximal end and a distal end, said catheter defining a lumen therethrough which communicates with a tip formed at said distal end of said catheter;
an adapter assembly slidably engageable with said distal end of said catheter, said adapter assembly comprising a rinse chamber isolated from a ventilation circuit; and
a suction control valve secured to said proximal end of said catheter and in communication with a vacuum source;
(b) retracting said catheter suction system towards said proximal end until said tip is positioned within said rinse chamber;
(c) instilling a rinse solution into said rinse chamber, wherein said rinse solution flows into said lumen and through said tip; and
(d) activating said suction control valve, wherein said rinse solution is aspirated through said lumen and into said vacuum source without interrupting the ventilation circuit.

25. A method for aspirating secretions from a passageway of a patient with a catheter suction system and rinsing said catheter suction system without interrupting a ventilation circuit, said method comprising the steps of:
-
(a) providing a catheter suction system comprising;
a catheter having a proximal end and a distal end, said catheter defining a lumen therethrough which communicates with a tip formed at said distal end of said catheter;
an adapter assembly slidably engageable with said distal end of said catheter, said adapter assembly comprising a rinse port isolated from a ventilation circuit;
a suction control valve secured to said proximal end of said catheter and in communication with a vacuum source; and
a lavage port secured to said suction control valve and adjacent said proximal end of said catheter, said lavage port being in fluid communication with said lumen. (b) advancing said catheter suction system towards said distal end, wherein said catheter slides through said adapter assembly until said tip is positioned within a passageway of a patient having secretions;
(c) instilling a lavage solution through said lavage port, wherein said lavage solution flows through said lumen to said tip within the passageway;
(d) activating said suction control valve, wherein said lavage solution and said secretions are aspirated from the patient;
(e) retracting said closed catheter suction system towards said proximal end until said tip is positioned within said rinse chamber;
(f) instilling a rinse solution into said rinse chamber, wherein said rinse solution flows into said lumen through said tip;
(g) activating said suction control valve, wherein said rinse solution is aspirated through said lumen and into said vacuum source without interrupting the ventilation circuit.
