Inflatable life jacket

Abstract

There is described an inflatable life jacket ( 1 ), comprising at least a first inflatable chamber ( 2 ) and a second chamber adjacent to said first chamber ( 2 ), characterized in that said second chamber ( 3 ) comprises in its inside at least one acid resin and at least one metal having an electrical potential lower than the hydrogen standard reduction potential, said second chamber ( 3 ) being provided with unidirectional means ( 5 ) able to allow the entry of water inside it.

         18 . An inflatable life jacket, comprising:
 a first inflatable chamber and a second chamber adjacent to the first chamber;   wherein the second chamber comprises therein at least an acid resin and at least one metal having an electrical potential lower than a hydrogen standard reduction potential;   the second chamber being configured to allow unidirectional entry of water therein.   
     
     
         19 . The life jacket of  claim 18 , wherein the second chamber is further configured to allow discharge of hydrogen therefrom. 
     
     
         20 . The life jacket of  claim 18 , wherein the at least one acid resin is selected from the group consisting of: sulphonic resin, phosphonic resin and carboxylic resin. 
     
     
         21 . The life jacket of  claim 20 , wherein the resin is a strong acid sulphonic resin. 
     
     
         22 . The life jacket of  claim 18 , wherein the at least one metal is selected from the group consisting of: aluminium, lithium, potassium, sodium, magnesium, zinc, barium, chromium, iron, lead, tin, nickel, cobalt, titanium, selenium, cadmium, manganese, vanadium, strontium, zirconium, calcium, rubidium, niobium, indium, germanium and molybdenum. 
     
     
         23 . The life jacket of  claim 22 , wherein the at least one metal is aluminium, magnesium or calcium. 
     
     
         24 . The life jacket of  claim 18 , wherein the second chamber also comprises therein a water soluble salt. 
     
     
         25 . The life jacket of  claim 24 , wherein the salt comprises a metal cation and an anion selected from the group consisting of: chloride anion, fluoride anion, bromide anion, iodide anion, sulphate anion, carbonate anion, nitrate anion, phosphonate anion, phosphate anion, acetate anion. 
     
     
         26 . The life jacket of  claim 25 , wherein the salt is chloride. 
     
     
         27 . The life jacket of  claim 26 , wherein the salt is sodium or calcium chloride. 
     
     
         28 . The life jacket of  claim 18 , wherein the second chamber is configured to allow unidirectional entry of water therein via a semipermeable membrane. 
     
     
         29 . The life jacket of  claim 18 , further comprising a third inflatable chamber adjacent to the second chamber and opposite to the first inflatable chamber. 
     
     
         30 . The life jacket of  claim 18 , wherein one or more of the first chamber and the third chamber is equipped with at least one inflation system with carbon dioxide. 
     
     
         31 . The life jacket of  claim 18 , wherein:
 one or more of the first chamber and the third chamber is provided with at least one tube configured to connect an inside of one or more of the first chamber and the third chamber with an external environment; and   the tube is provided with a valve configured to allow entry of air inside the one or more of the first chamber and the third chamber, but to prevent discharging of the air there from.   
     
     
         32 . The life jacket of  claim 18 , wherein the second chamber is positioned during use to be in contact with a user and the first chamber is positioned during use to be in contact with an external environment. 
     
     
         33 . The life jacket of  claim 18 , further comprising a container containing a water and glucose solution. 
     
     
         34 . The life jacket of  claim 18 , further comprising one or more inflatable aids connectable to the second chamber.
