A flexible fiber optic bronchoscope with one-way valve is provided in which a unidirectional flow control valve is inserted between the bronchoscopic manifold port and the sealing cap. A compressible diaphragmatic seal with radial slits separate resiliently returnable valve flaps that deformably compress around the shaft of any inserted conduit. A circumscribing housing for typically affixing along a lower receiving ring to the bronchoscopic manifold port to which the sealing cap would normally be attached. An upwardly extending, annular attachment protuberance thereby provides the attachment for the conventional sealing cap.

What is claimed is: 1. A flexible fiber optic bronchoscope one-way valve for use with an otherwise conventional bronchoscopic manifold having a bronchoscopic manifold port covered by a sealing cap, wherein said cap may be opened and closed to allow the introduction and removal of the fiberoptic bronchoscope, said one-way valve comprising: a circumscribing housing for connection to said manifold port in place of said sealing cap along a lower receiving ring; an upwardly extending, annular attachment protuberance formed opposite said receiving ring for providing an attachment structure for the sealing cap of the bronchoscopic manifold port; and, a unidirectional flow control valve supported within said circumscribing housing; wherein when a fiberoptic bronchoscope is insertable through said flow control valve and into the bronchoscopic manifold port. 2. The flexible fiber optic bronchoscope one-way valve of claim 1, said unidirectional flow control valve comprises a compressible diaphragmatic seal with a plurality of radial slits. 3. The flexible fiber optic bronchoscope one-way valve of claim 2, wherein each said slit separates adjacent resiliently returnable valve flaps that deformably compress around any inserted conduit. 4. A removable one-way valve for use with an otherwise conventional bronchoscopic manifold having a bronchoscopic manifold port covered by a sealing cap, wherein said cap may be opened and closed to allow an introduction and a removal of a fiberoptic bronchoscope, said one-way valve comprising: a circumscribing housing for connection to said manifold point in place of said sealing cap along a lower receiving ring; an upwardly extending, annular attachment protuberance formed opposite said receiving ring for providing an attachment structure for the scaling cap of the bronchoscopic manifold port; and, a unidirectional flow control valve supported within said circumscribing housing; wherein said flow control valve is attached to the attachment for the removed sealing cap when a flexible fiber optic bronchoscope is insertable through said flow control valve and into the bronchoscopic manifold port for a medical procedure, said one-way valve is unattached from the attachment after the procedure so that the scaling cap can be therefore replaced back on the manifold port. 5. The flexible fiber optic bronchoscope one-way valve of claim 4, said unidirectional flow control valve comprises a compressible diaphragmatic seal with plurality of radial slits. 6. The flexible fiber optic bronchoscope one-way valve of claim 4, wherein each said slit separates adjacent resiliently returnable valve flaps that deformably compress around any inserted conduit.
