[L., a small reed] A tube or sheath that encloses a trocar. After the device is inserted into a blood vessel, body cavity, duct, or hollow organ, withdrawal of the trocar lets fluid drain (so that it can be collected or sampled) or escape.
NEEDLELESS CANNULAE USED TO CONNECT AN ADDITIVE TO PRIMARY INTRAVENOUS INFUSIONS (A) Threaded-lock cannula; (B) Lever-lock cannula
Tubing used to deliver oxygen at levels from 1 to 6 L/min. The nasal prongs of the cannula extend approx. 1 cm into each naris and are connected to a common tube, which is then connected to the oxygen source. It is used to treat conditions in which a slightly enriched oxygen content is needed, such as emphysema. The exact percentage of oxygen delivered to the patient varies with respiratory rate and other factors.
