Abstract: Disclosed is a modular hand-held device for use with a suction irrigation electrosurgical tool having a rear inlet/outlet port provided with an electrically conductive surface. It has a rear handle member, a middle valve member and a front member. An electrical connection device is provided for supplying electrical energy to the electrically conductive surface when the rear inlet/outlet port of the suction irrigation electrosurgical tool is received into an inlet/outlet port of the front member. A first mechanical connector is provided for removably connecting front ports of the handle member respectively to the corresponding rear ports of the middle valve member, and a second mechanical connector is provided for removably connecting an inlet/outlet front port of the middle valve member to an inlet/outlet rear port of the front member. This device can be fully dismantled, thereby making it possible to clean and sterilize all its component for further uses.

Abstract: A device for the simultaneous delivery of beta 2 agonists and oxygen to a patient. This device comprises a main chamber, an adaptor at one end of the chamber to accomodate a metered dose inhaler, and a mask or mouthpiece detachably mounted at the other end of the main chamber. A tube of given length is connected to and in open communication with the main chamber at one end, and open to air at the other end. A unidirectional valve is placed in the tube at a short distance from the end connected to the main chamber mounted in such a manner as to allow flow circulation within the tube towards the main chamber exclusively. An auxiliary tube is connected to and in open communication with the tube at one end, at a given distance from the unidirectional valve away from the main chamber. The other end of this auxiliary tube is devised to accomodate an oxygen source.
