RESPIRATORY PROTECTION - ANDNINGSSKYDD

The present invention relates to a respirator against hot air, for example for sauna use, which respirator comprises a plastic plate substantially shaped in the shape of a face, at least at the respiratory organs, in which a metal cell is arranged, through which at least most of the inhaled air is sucked.

Even if the temperature of the sauna is reasonably low, throwing water on hot stove stones will cause water to evaporate, causing water vapor above 100’C to spread into the steam room, causing the sauna occupants to breathe for a while. For a healthy person, there is no noticeable danger of this, but for heart patients and asthmatics, it causes not only embarrassment but even health harm. The normal defense mechanism against hot water vapor when throwing steam is to put your hands in front of your face, 20 which is not particularly effective and especially not hygienic.

Respirators known from other contexts, which are mainly intended against cold air, are already known. One such respirator is shown in the applicant's own registered FI model 12689. However, such a protector is not as such suitable for sauna use.

The object of the present invention is to provide a respirator against hot air, which also allows asthmatics and heart patients to take a sauna without any health risk. The respirator according to the invention is characterized in that a removable water-absorbing hood is arranged on the respirator.

A preferred embodiment of the respirator according to the invention is characterized in that the water-absorbing hood is made of 2 86960 mesh fabric, preferably a cotton fabric with holes, which is wetted before use.

Another preferred embodiment of the respirator according to the invention is characterized in that the hood is made substantially in the shape of a respirator and is provided with at least one fastening element by means of which the respirator together with the hood can be fastened in front of the wearer's face.

10

In yet another preferred embodiment of the invention is characterized in that the fastening member is a rubber band which is passed through holes in the front of the hood and extends mounted in place around the user's head.

When using the respirator according to the invention, throwing steam does not cause any difficulty in breathing, since the cell of the respirator condenses the water vapor and prevents it from entering the respiratory system. At the same time, the wet hood around the respirator cools the inhaled air to the comfort of the user. This is especially important for asthmatics and heart patients.

In the following, the invention will be explained in detail by means of preferred embodiment examples with reference to the accompanying drawings, in which

Figure 5 shows a hooded respirator according to the invention mounted in front of a user's face.

The respirator shown in Figures 1 and 3 comprises a substantially face-shaped plastic sheet 1, which is preferably made of polycarbonate plastic. The plastic sheet, which can also be retrofitted to exactly fit the shape of the user's face, covers at least the nose 10 and the mouth when in place, as shown in Figure 5. Mounted substantially at the user's mouth on the plastic plate 1 is a metal cell 2, which most preferably consists of adjacent, in this case substantially vertical, coil springs 2a, 2b, etc., which are preferably made of stainless steel. A respirator of this kind is shown in the applicant's previously registered FI model 12689. The coil springs are at least almost attached to each other and a second parallel but smaller 20 coil spring (not shown in the figures) is mounted inside each spring to increase the mass of the honeycomb. To facilitate the handling of the respirator, a handle 3 is arranged at its lower edge, which may be integral with the plastic plate 1. In addition, a hole 4 (Figures 3 and 4) can be formed in the handle, by means of which, for example, the respirator can be hung on a hook or the like when not in use. It can be seen from Figure 3 that in this embodiment a groove 8 for the nasal arm is formed in the upper part of the respirator.

In Figures 2 and 4, a water-absorbing hood 5 made of a mesh fabric, for example a cotton fabric with holes, is mounted on the respirator according to the invention. The hood is shaped so that, when mounted on the respirator, it follows the shapes of the plastic plate 1 and the cell 2 of the respirator and extends to the handle 3. On the face side, the hood succumbs so that when fitted to the wearer's head, the respirator fits snugly against the face. The wearer's face is then naturally in contact only with the hood material, which feels comfortable against the face. In this embodiment, the hood is provided with two fastening members 6 and 7, which are, for example, 5 rubber bands. The lower rubber band 7 is preferably threaded entirely through the holes of the Hood around the Hood. Because the rubber band stretches, it allows the Hood to be mounted over the respirator, but in the rest position it tightens the lower part of the Hood over the hand position 3. Mounted on the top of the hood is a second rubber band 10 6, which is also arranged through holes in the hood material on the front of the hood, but on the back of the hood it is left free to be carried behind the wearer's head to attach the respirator, as shown in Figure 5.

The principle of use and operation of the respirator is as follows: when going to the sauna, a hood 5 is installed on top of the respirator, after which the respirator with the hood is soaked in water, for example, and installed on the face of the user as shown in Fig. 5. When steam is thrown, the cell 2 consisting of coil springs receives hot water vapor, which, thanks to the wet Hood, cools and condenses rapidly and is even stored for the most part in the slots of the coil springs. This prevents hot water vapor from entering the user's respiratory system and also allows asthmatics and heart patients to take steam in the normal way. When the sauna is stopped, the hood can be easily removed from the respirator and washed, for example.

It will be clear to a person skilled in the art that the invention is not limited to the above-mentioned exemplary embodiments, but can be varied within the scope of the appended claims. Thus, for example, the shape of the cover and the material and shape of the Hood, as well as the mounting head, may naturally vary. Only one preferred embodiment is shown in the accompanying description. It is further clear that the respirator can also be used as a frost protection if necessary, although in this case the hood is not wetted or the sauna hood may not be used at all, but a respirator is arranged inside a collar or the like, for example.
