Apparatus and methods are disclosed by which a closed ventilating system accommodates multiple access to the respiratory system of an intubated medical patient. Access to the respiratory system is accomplished via one or more access ports through an attached accessory device in order to ventilate the lungs of the patent with gas or gasses, aspirate secretions from the lungs, oxygenate the lungs, visually inspect selected parts of the respiratory system, sample sputum and gasses, sense parameters such as flow rates, pressure, and temperature, flush the respiratory tract with washing solution, and/or administer medication, gasses, and/or lavage. The embodiments of the present invention may have such accessory devices permanently fixed to the adaptor or may be removable and replaceable. Access control means may be provided whereby one or more access ports are selectively aligned with the adaptor in order to allow passage of an attached accessory device therethrough.

Multiple access adaptors for monitoring, sampling, medicating,

Apparatus and methods are disclosed by which a closed ventilating system accommodates multiple access to the respiratory system of an intubated medical patient without comprising the closed character of the system. Access to the respiratory system through one or more access sites of the closed system apparatus is provided at proximal adapter ports to ventilate the lungs of the patient with gas or gases, to aspirate secretions from the lungs, to oxygenate the lungs to eliminate or reduce residual co.sub.2 therefrom, to visually inspect selected parts of the respiratory system, to sample sputum and gases, to sense parameters such as flow rates, pressure, and temperature, to flush with washing solution, and/or to administer medication, gases, and/or lavage.

Medical multiple access low dead space anti-microbial

A medical lavage apparatus for body cavities comprising a housing having parallel irrigation and aspiration cylinders with captive plungers extending in bores thereof from a first end and pairs of check-valves positioned in parallel, smaller, offset cylinders located at second ends such that reciprocal movement of the each plunger in each cylinder performs the function of a one-way pump. The plungers are held captive and aligned by guide-stops proximally disposed in each cylinder. Each plunger comprises a seal disposed at the distal end thereof which inhibits communication between the pairs of check-valves in each cylinder when the plunger is fully seated in the cylinder. Novel jam-free dome shaped, slit check-valves are disposed to be the pair of check-valves in the aspiration cylinder in one embodiment and in irrigation cylinders as well in other embodiments. The dome shaped valves are described for use in other medical fluid control applications, as well. A septum formed of intersecting semi-circular-in-cross-section baffles joins the adjacent outer ends of tale irrigation and aspiration check-valve cylinders so as to allow full fluid streams flowing from these outer ends to flow together at an angle. The septum and associated irrigation and aspiration check-valve cylinders are enclosed in a common exchange tube which leads to a common patient tube connecting nozzle. A special patient tube securing attachment is disposed on the connecting nozzle.

A gravity drainage system for manual removal of liquid accumulated in ventilating tubing which does not require interruption of ventilation or manual disassembly of drainage of the tubing. Periodic evacuation of accumulated liquid from the drainage system without interruption of ventilation is also facilitated.
