Bronchoscopy oxygenation system
First Claim
1. An open bronchoscopy oxygenation system comprising, a) an orifice for receiving oxygen joined with, b) a reservoir housing containing a pressure relief valve, to prevent excessive oxygen pressure, c) a stopcock attached to a passage for receiving oxygen and attached to a second passage for receiving an instrument, and with the stopcock being supplied with a handle controlling the flow through the internal passages, thus allowing for the passage of oxygen and/or an instrument through said passages, and d) with the stopcock being attached to a passage running from said stopcock allowing for the passage of either oxygen, an instrument or fluids to a patient such that the patient may be safely treated.

Abstract
A bronchoscopy oxygenation system having a channel for inserting alternately an instrument or fluids and for delivering oxygen to a patient. The system being provided with pressure relief vent and a pressure relief valve for the relief of excessive oxygen pressure. The bronchoscopy oxygenation system may be used during bronchoscopy and with patient suctioning, bronchoalveolar lavage or biopsy. The bronchoscopy oxygenation system is intended to be used with a conventional bronchoscope.

6. A method of obtaining a tissue specimen from a patient comprising employing a bronchoscopy oxygenation system comprising,
a) an orifice for receiving oxygen joined with, b) a reservoir housing containing a pressure relief valve, to prevent excessive oxygen pressure, c) a stopcock attached to a passage for receiving oxygen and attached to a second passage for receiving an instrument, and with the stopcock being supplied with a handle controlling the flow through the internal passages, thus allowing for the passage of oxygen and/or an instrument through said passages, and d) with the stopcock being attached to a passage running from said stopcock allowing for the passage of either oxygen, an instrument or fluids to a patient such that the patient may be safely treated. e) with the method steps comprising the steps of alternately supplying oxygen to the patient through said oxygen passage and turning the stopcock to perform a biopsy through said instrument passage with a biopsy forcep and in that way preventing hypoxemia in said patient while said tissue specimen is obtained.
