Abstract

An oxygen mask for supply of oxygen to a nose and mouth portion of a patient, which mask comprises fixing means (3) for fixing of the mask (1) over said portion. The mask (1) is formed of a filter material (2) and comprises an outlet tube (6) arranged in the mask (1) and which is provided with outlet holes (8) for oxygen supplied by means of the tube (6).

Description

Figure imgf000002_0001
hand the mask does not restrain or distort the conversation of the patient.
Preferably the tube in the oxygen mask is provided with a large number of outlet holes and is arranged at a distance within and along a greater part of the edge of the mask. This secures an even oxygen flow.
The filter material may, for example, be a paper filter material. Such a material is almost odourless and further stops odours from the environment, such as smoke.
A preferred design of the mask is a substantially hemispheric form.
The invention will now be described by means of a number of exemplifying embodiments and with reference to the appended drawings .
Fig. 1 illustrates in a side view a first embodiment of an oxygen mask according to the present invention in usage mode,
Fig. 2 illustrates in an inside view the oxygen mask of fig. 1,
Fig. 3 illustrates in an inside view a second embodiment of an oxygen mask according to the present invention,
Fig. 4 illustrates in an inside view a third embodiment of an oxygen mask according to the present invention.
According to a first embodiment of the present invention an oxygen mask 1 is formed of a paper filter material 2, which is substantially designed as a hemisphere and which comprises fixing means 3 for fixing over the nose and mouth portion of the patient, for example by means of rubber bands 3 attached to the sides 4 of the mask 1, which rubber bands are adjustably connected in the neck of the patient (not shown) .
Oxygen is supplied to the mask by means of a supply tube 5, which branches off into two outlet tubes 6. The branching preferably occurs inside a branching box 7 and the branched outlet tubes 6 run through two holes 9 in the lower edge of the mask 1 into the mask 1. In the first embodiment of the oxygen mask 1 of the invention the two branched outlet tubes 6 form a common loop without any interruption, which is arranged a small distance from, on the inside, and along the edge of the mask 1. See fig. 2. The outlet tube 6 is provided with outlet holes 8 arranged along the outlet tube 6 and preferably directed towards the centre of the mask 1. An advantageous flow of oxygen is achieved by providing the outlet tube 6 with a large number of outlet holes 8.
In fig. 3 a second embodiment of the present invention is illustrated where the two branched outlet tubes 6 run along the edge of the mask 1, but not all the way up so that they meet, but forms a U-configuration.
In fig. 4 a third embodiment is illustrated where the supply tube 5 changes into being an outlet tube 6, without branches, approximately where the tube runs through a hole 9 into the mask 1. The outlet tube 6 is arranged along the majority of the edge of the mask 1, forming a hook configuration.
Of course, this mask may also be used for other gases, for example laughing-gas.
