摘要： A stethoscopic device for use with an endotracheal tube of the type adapted to be inserted through the mouth cavity of a surgery patient and into the trachea of the patient to position the outer end of the tube exteriorally of the patient's mouth and position the inner end of the tube proximate the patient's lungs to facilitate the delivery of anesthesia through the tube to the patient's lungs and/or to facilitate the delivery of a gaseous substance from a breathing machine through the tube to the patient's lungs during the surgical procedure. The invention devide includes a tube member adapted to be fitted at one end thereof in the outer end of the endotractheal tube and fitted at the other end thereof to a breathing tube leading to the anesthesia/breathing machine and a drum member positioned radially of the tube member and defining a membrane communicating with an aperture in the side wall of the tube member. The drum member further defines a chamber radially outwardly of the membrane and a fitting in the side wall of the drum member is adapted to be connected to the hose of an aural stethoscope so that the attending medical person may readily monitor the nature and frequency of the breath sounds emitted by the patient during the anesthesia/surgical procedure.

摘要： A needle assembly especially suited for hypodermic syringe use in which an axially collapsible sleeve is positioned over the needle. The sleeve includes an upper axially rigid portion sized to mount over the base portion of the needle, an axially collapsible intermediate portion, and an axially rigid lower portion defining a central bore sized to telescopically receive and protect the lower pointed end of the needle. In use, the sleeve selectively collapses axially as the needle enters the subject so that the point of the needle is never exposed during insertion, and selectively extends axially during withdrawal of the needle so that again the pointed tip of the needle is never exposed.
