CONDUITE D'ALIMENTATION EN GAZ

GAS SUPPLY CONDUIT

Abrégé anglais

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.

Revendications

WHAT I CLAIM IS:
1. A gas supply conduit that can be
connected to an oxygen mask for artificial
respiration of a patient, comprising:
a portion made of porous or fine-pored
material via which gas in said conduit is
discharged to the atmosphere.
2. A gas supply conduit according to claim
1, wherein said porous or fine-pored portion is
replaceably disposed in said gas supply conduit.
3. A gas supply conduit according to claim
2, wherein said portion is made of sintered
material.
4. A gas supply conduit according to claim
2, wherein a connector member is disposed on said
porous or fine-pored portion and serves for
connection to an oxygen mask.
5. A gas supply conduit according to claim
4, wherein a sleeve is rotatably mounted on said
porous or fine-pored portion remote from said
connector member.

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

2153614
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~
