Definitions

  • the invention relates to a rescue suit or life jacket according to the preamble of claim 1.
  • the cold protection suit includes a respiratory protection device, which comprises a CO 2 -binding and thereby O 2 -generating cartridge, which is connected via a mouthpiece with the user. This cartridge regenerates the air exhaled by the user by binding the CO 2 contained therein and replacing it with O 2 .
  • a respiratory protection device which comprises a CO 2 -binding and thereby O 2 -generating cartridge, which is connected via a mouthpiece with the user. This cartridge regenerates the air exhaled by the user by binding the CO 2 contained therein and replacing it with O 2 .
  • Methods and apparatus for the regeneration of exhaled air are known from the prior art, for example from the DE 199 10 845 C1 , here regularly regeneration substances are used, which extract the carbon dioxide from the exhaled air.
  • the substance for the regeneration of the exhaled air filled in pockets which are formed by an inner suit of two for breathing gas semipermeable walls which are connected at certain intervals to form these pockets together, in particular sewn or glued.
  • the inner suit is arranged between two layers of the cold protection suit, namely an inner body layer and an outer layer.
  • inlet and outlet channels between the body layer and the inner suit or between the inner suit and the outer layer are formed.
  • the exhaled by the user air flows through an exhalation hose into the inlet channels and through the semipermeable wall in the filled with the regeneration substance pockets of the inner suit.
  • the exhaled air is regenerated by the CO 2 -binding and thereby O 2 -releasing regeneration substance for use as breathing gas and flows through the outlet channels and via a discharge tube in a space around the breathing mask, which is hermetically sealed by a shield to the environment, what the sign for the cold-weather suit covering the entire body of the user is connected and covers the face of the user.
  • This respiratory protection proves to be disadvantageous because the introduced in the pockets of the inner suit regeneration substance can not be changed if it has become used or unusable.
  • the cold-weather suit is very complicated in structure, in particular due to the multi-layer structure with an inner body layer, an outer outer layer and the interposed inner suit with the pockets for receiving the regeneration substance. The production of this suit is therefore complicated and expensive.
  • the invention is therefore based on the object to show a rescue suit or life jacket with a breathing apparatus, which allows efficient ventilation of the user and at the same time has a simple structure that can be produced easier and cheaper.
  • an exchange of used regeneration substance is to be made possible in a simple manner.
  • the rescue suit or the lifejacket should also be able to leave in case of emergency a damaged and lying on the seabed submarine to ascend from great depth to the water surface.
  • a life jacket is shown, which is created in an emergency by the user to get out of a submerged in deep water submarine and reach the water surface, there to a rescue, for example, by a lifeboat or a rescue helicopter to waiting.
  • the lifejacket is equipped with a respirator 1.
  • the lifejacket on an inflatable cavity which is designed as a buoyancy stolen 20 and disposed in the collar region of the vest and so at least partially surrounds the neck of the user.
  • the lifejacket shown in Figure 1 consists essentially of this buoyancy stolen and the breathing apparatus.
  • the arrangement shown in Figure 1, consisting of the inflatable cavity in the form of buoyancy stolen 20 and the respirator 1 can also be integrated into a rescue suit comprising an upper and a lower part (leg part) which completely clothe the user.
  • a rescue suit is preferably a single-layered suit of waterproof material in which the buoyancy stolen 20 and the breathing apparatus 1 are integrated as shown in FIG.
  • the reservoir 14 shown in FIG. 1 and described in more detail below can be arranged either on the back or on the front side of the suit, for example in the chest or hip region.
  • the lifting stole 20 is filled with gas from the storage containers 14, in particular air, in order to generate a buoyancy in the water.
  • the breathing apparatus 1 In order to supply the user still in the submarine and during the ascent to the water surface with breathing gas, the breathing apparatus 1 is provided, which has a breathing mask with a mouthpiece 2, which applies the user in a conventional manner, and an air cleaning device 3, for regeneration the air exhaled by the user.
  • the mouthpiece 2 of the breathing mask has an exhalation opening 11, in which the user exhales used air, and an inhalation opening 4, from which the user regenerated breathing air and / or fresh breathing gas is supplied for inhalation.
  • Check valves are provided in the mouthpiece 2, which open the exhalation opening 11 when the user exhales and close the inhalation opening 4 and, upon inhalation, inversely open the inhalation opening 4 and close the exhalation opening 11.
  • the air purification device 3 contains a regeneration substance 7 which removes the carbon dioxide from expired and carbon dioxide-enriched air or at least reduces the carbon dioxide content of the exhaled air and possibly simultaneously enriches it with oxygen (O 2 ).
  • regeneration substances are known from the prior art of the respiration devices and are referred to there, for example, as “soda lime” or “soda lime”.
  • These known regeneration substances are carbon dioxide absorbers, which convert carbon dioxide into a carbonate with formation of oxygen and thereby regenerate spent and carbon dioxide-enriched exhaled air into oxygen-rich breathing air. In this regeneration process, the regeneration substance is consumed.
  • the known as "soda lime” substances are mixtures of sodium and calcium hydroxide and water.
  • barium lime can be used as a regeneration substance, which consists of a mixture of barium hydroxide and water.
  • any other substance as a regeneration substance which extracts carbon dioxide from the exhaled air and / or enriches it with oxygen in order to regenerate the exhaled air for use as respiratory gas.
  • the air cleaning device 3 is on the one hand via a connecting line 10 with the exhalation port 11 of the mouthpiece 2 and on the other hand with the inflatable cavity, so the interior of the buoyancy stolen 20 in connection.
  • the inflatable cavity of the lifting stolen 20 thus serves as counter-lung 5 for the storage of regenerated breathing air, which from the air cleaning device 3 after the regeneration process in the Counterlung 5 flows.
  • the exhaled by the user air is for this purpose passed through the exhalation port 11 of the mouthpiece 2 and the connecting line 10 in the air purification device 3, where it is regenerated by removal of carbon dioxide and / or enrichment of oxygen and finally flows as regenerated breathing air into the counterlung 5.
  • the counterlung 5 communicates with the inhalation opening 4 of the mouthpiece 2 via a further connection line 15, via which the breathing air stored and regenerated in the counterlung 5 is supplied to the user for inhalation.
  • the breathing apparatus 1 thus runs a closed circuit of the breathing air exhaled by the user in the exhalation port 11, regenerated in the air cleaner 3 and stored in the counterlung 5 and finally inhaled again via the inhalation port 4 by the user.
  • the air cleaning device 3 shown in section in FIG. 2 comprises a flexible container 6 made of an airtight material, for example in the form of a collapsible bag or canister made of plastic or textile fabric.
  • the container 6 is made of polyurethane coated nylon fabric.
  • FIG 3 the container 6 is shown in perspective in two different views.
  • the container 6 has a circular in the illustrated embodiment air inlet opening 8, which is arranged in a side wall of the container 6 in the upper region.
  • an air outlet opening 9 is provided, which is covered by a grid or net-shaped cover 13.
  • the cover 13 can be an air-permeable foam structure or textile fabric or a wire mesh.
  • the container 6 is, as indicated in Figure 2 by dots filled with a regeneration substance 7, preferably full to the brim.
  • the cover 13 in the bottom of the container 6 is intended to prevent the granular or pulverulent regeneration substance 7, for example soda lime or barium lime, from entering the counterlung 5.
  • an air passage through the air outlet opening 9 in the bottom of the container 6 is to be ensured in the counterlung 5.
  • the air inlet opening 8 and the air outlet 9 of the container 6 are arranged at the greatest possible distance from each other, so that the air flowing into the container 6 through the air inlet 8 in the air Essentially through the entire volume of the container must flow to leave the container 6 through the air outlet opening 9.
  • the largest possible contact time or the largest possible effective contact area of the air flowing through with the Regeneration substance 7 and thus an efficient regeneration of the air by replacing the carbon dioxide (CO 2 ) by oxygen (O 2 ) guaranteed.
  • the container 6 is located within the inflatable cavity of the rescue suit or life jacket, ie inside the counterlung 5, as can be seen from the region of FIG. 1, wherein the air outlet opening 9 opens into the inflatable cavity and thus with the interior of the Buoyancy stolen 20 communicates.
  • a valve 12 Arranged in the air inlet opening 8 of the container 6 is a valve 12, which is inserted in an opening 19 of the tissue 21 surrounding the inflatable cavity or forming the lifting stolen 20.
  • the valve 12 has an outlet 25, through which the air flowing into the valve 12 flows into the air inlet opening 8 of the container 6.
  • the air inlet opening 8 or at least the outlet 25 of the valve 12 is covered by a screen 24 in order to prevent the granular or powdery regeneration substance 7 from entering the valve 12 and clogging it.
  • the screen 24 is formed dome-shaped or basket-like and extends into the interior of the container 6.
  • the screen 24 may be formed of a grid of metal or an air-permeable textile or plastic fabric.
  • a breathing gas line 16 is flanged, which is in communication with two reservoirs 14.
  • breathing gas such as breathing air or pure oxygen stored.
  • the two reservoirs 14, at the outlet of manually operable valves 17 are provided via a high-pressure connection line 16a with each other and via a pressure reducing valve 18, with which the pressure in the line 16 is reduced to a constant value, with the breathing gas line 16 in connection ,
  • a pressure reducing valve 18 With which the pressure in the line 16 is reduced to a constant value, with the breathing gas line 16 in connection ,
  • the stored in the reservoirs 14 breathing gas can flow through the container 6 in the counterlung 5, since the breathing gas is in the reservoirs 14 under pressure, for example below 200 bar.
  • the volume of the reservoir 14 is typically about 1 liter per reservoir.
  • the counterlung 5 can be supplied, if required, with fresh breathing gas in addition to the regenerated breathing air from the air purification device 3, the Amount of regenerated breathing air with between 35 and 70 1 / min is significantly greater than the amount of additionally supplied from the reservoirs 14 breathing gas (up to 5 1 / min). Furthermore, by the stored in the reservoirs 14 breathing gas the buoyancy stolen 20 are inflated when the user has to get off the submarine at great depth to rise to the water surface.
  • the gas quantity flowing into the container 6 from the storage containers 14 is preset.
  • the valve 12 may be equipped with a flow meter to detect and, if necessary, control the amount of gas flowing into the container 6.
  • a control device is then provided which supplies the quantity of inflowing respiratory gas detected by the flowmeter and the pressure in the counterlung 5 determined via a sensor arranged in the counterlung 5 receives and regulates the positions of the valves 12 and 18 as needed.
  • a pressure relief valve 24 can be provided, via which a possibly prevailing in the counterlung 5 overpressure can be reduced.
  • valve 12 can be removed or unscrewed. By removing the valve 12, the interior of the container 6 is accessible via the air inlet opening 8 and the regeneration substance 7 filled therein can be removed if necessary and replaced by fresh regeneration substance 7.
  • a screw, plug, clamping or latching connection with the fabric 21 is provided on the valve 12.
  • the respirator of the rescue suit according to the invention proves to be much more efficient, because a well-functioning and closed breathing air circuit has been realized with separate inhalation and exhalation channels.
  • the rescue suit according to the invention or the lifejacket according to the invention proves to be much more variable, since the counterlung 5 is used on the one hand for storing regenerated breathing air and on the other hand as a lifting stolen 20, when the user get off the submarine from great depth and to the Water surface must ascend.
