Abstract
A gas supply conduit that can be connected to an oxygen mask for artificial respiration of a patient. The conduit has a portion made of porous or fine-pored material that can be replaceably introduced into the gas supply conduit and via which excess air and gases exhaled by the patient are discharged to the atmosphere.
Description
215361~
GAS SUPPLY CONDUIT
Background of ~he Invention The present invention ~elate~ to a ga~ supply conduit that includes a portion ~ia which ga8 can be discharged to the atmosphere a~d which can be con~ected to a breathing ~r oxygen mask for the - 5 artificial re~pirat-on of a patient.
For the artificial re~piration of ~ pa~ient, ~ reepirator is connected to an oxygen mask vi~
the gas supply conduit. This conduit i8 provided with holes via which the excess air and the ~aae~
exhaled by the patient are discharged to the atmosphere. These hole~ are provided in the ~as suppl~ conduit aa clo~e as possible to tho oxygen ~ask so that the entire quantity of ga6e~ that are exhaled do ~ot flow back into the re~pirator.
Un~oxtunately, the dischar~e of the ga~es that are exhaled via ~uch holes is undesirable and annoying due to the noise that re~ult~ ~uriny frequent and long lasting artificial reapiration, for example during the treatment of sleep apnea. The air atream that exits these hole~ can al80 cause secondary illnesses such as conjunctivitis It is therefore an o~j ect of the pre~ent in~eneion to provide a patient friendly discharge of the exhaled ga8e8 and the excess air during artificial re~piration ~r re~u~citation.
Brief ~e~crip~ion of the ~rawing Thi~ object, and other objects and advantage~
of the present invention, will appear more clearly from the following .~pecification in conjunction with the accompanying schematic drawin~, which i~
a partially cro~-6ectioned view of one exemplary embodiment of the inventive gas Yupply conduit for th~ ~rtlficial re~piration of a p~tien~.
Summary of the Inventio~
The gas ~upply conduit of the present invention i~ characterized primarily by a portion ~ade of porou~ or in-porQd material via which ga~
i~ the conduit i~ di~charged to the atmosphere.
The exhale~ ga~ a~d the e~ces~ air are di~ch~r~ed to the atmosphere via the inventive porou~ or fine-pored portion of the gas supply conduit witho~t a concentrated air stream being produced, ~ince the ai~ flows outwardly toward all side~ t~rough the pores of the material. Any noise that i~ generated thereby i~ generally not noticea~le. The porous po~tio~ i~ expedientl~
made of a sintered ~aterial and can be replaceably di~po~ed in the ga~ ~upply con~uit. At a distance o~ only a few centimeters beyond th~ porou~
portion of the gas ~uppl~ cond~it, ~he ~ tream can no longer ~e me~sured, thus avoiding ad~ersely affecting the patient or others with a concentrated air ~tream.
Further ~pecific feature~ of the present in~ention will be described in det~il ~;ub~e~quent ly .
De~3cription of the~ Preferred E:Tnbodiment In the i~ luYtrated embodiment, the illus~r~ed conduit ~ection includes a connector me~r~ex 1 that i~ made of ela~tomeric ~n~teri~l; ~he free end of the connector member 1 can be connected to a non-illu~trated breathing or oxygen ma~k. The other end of the connector member 1 i~
disposed on a portion 2 of the ga~ supply co~duit.
Thi~ portion 2 is made o~ a porou~ material through which the exhaled ga~ and the exce~ ai~
can escape outwardly into the at~osphere. A
rotatably supported sleeve 3 iQ snapped onto that end of the portion 2 that is remote from the connector member l; a non-illuitra~ed hose that is ~onnected to a respirator can be di~poced on the ~lee~e 3.
The presen~ invention is, of courBe~ in no 21~3G14 way restricted to the specif ic di~closure of the cpecif~caeion and drawing, but al~o encom~a~se~
any modifications with~n the scope of the appended clai~
