Description

Heating device with exothermic reaction for the human body.

The present invention relates to a heating device for the human body intended to provide heating for the body of a chilly person and more particularly to a heating device for the human body which provides heating using the exothermic release generated by a reaction of oxidation and reduction of a metal oxide or the like.

A heating device for the body has a very wide range of applications with the aim, not only, of treating neuralgia, rheumastism, etc. but also to warm a person who is chilly or working outside during the winter. Recently, a heating device for the body has been proposed which uses exothermic heat generated by a metal oxide or the like which is more easily usable than gas oil or agglomerated coal. The conventional body heating device using an exothermic reaction has the disadvantage of producing an excessively high exothermic temperature. It is recognized that it is preferable to heat the human body to approximately 52 to 550C during a therapeutic application and for the warming of the human body. However, the conventional body heater disadvantageously heats to a higher temperature,
that this preferential temperature and sometimes heats
at a temperature as high as 70 to 800C, which is
translated into danger in the event of direct contact with
the body. The conventional body heater has the other disadvantage of having a
exothermic reaction of very short duration of the order ap
approximately 5 to 6 hours at the appropriate temperature.

It is therefore necessary to replace several
times the heater which results in disadvantages and an uneconomic character. Some
conventional body heaters
involve mixing with copper dioxide so
to increase the duration of the exothermic reaction, which
gives certain results. However, copper is toxic and introduces the danger of a harmful effect on the body.
human.

The object of the present invention is to eliminate the disadvantages
above mentioned mentions of the conventional device
of heating for the human body which provides heating
using an exothermic reaction and it is based
on the discovery that it is possible to overcome all
disadvantages of the conventional heater for
the human body by mixing a solid fibrous agricultural waste impregnated with calcium chloride
such as cooking salt or a compound salt or the like.

Accordingly, an object of the present invention is to
provide a heater for the human body using an exothermic reaction which can heat up
an effective temperature remaining within the safety limits
which rite can be used for the elderly or
young, without any risk.

 Another object of the present invention is to provide a heating device for the human body using an exothermic reaction which can heat continuously for an extremely long time, which eliminates the drawback of frequent exchanges.

Yet another object of the present invention is to provide a heating device for the human body using an exothermic reaction which presents no danger of pollution during use and at the time of disposal since it uses no toxic substance.

Yet another object of the present invention is to provide a heating device for the human body using an exothermic reaction usable in an effective manner to treat neuralgia, soften human skin and soften the human muscle which contains a particular preparation.

Yet another object of the invention is to provide a heating device for the human body using an exothermic reaction which is simple to handle and can be suitably used to protect from the cold or for therapeutic purposes in the case of people. elderly and young people, either at home, at work or in hospital.

According to a preferred aspect of the present invention, it relates to a heating device for the human body using an exothermic reaction which comprises an exothermic substance in the form of particles containing a main constituent leading to the reduction of a metal oxide by air and humidity introduced from the outside to provide heating by the chemical reaction thereof, a solid fibrous waste of agricultural origin impregnated with sodium chloride, magnesium sulphate or a composite salt, and an air permeable bag which is filled with the particulate exothermic substance and the fibrous solid waste of agricultural origin.

The above object and other objects attached to it and the characteristics of the invention will appear on reading the description given below with reference to the attached drawings in which
The single figure is an elevation view
frontal with partial tearing of a
embodiment of the device
body heating performed in accordance
to the present invention.

The invention will be described in more detail below with reference to the specific example of the device for heating the body containing a composition which will be described below and an example of which is shown in the attached drawing.

The exothermic substance in the form of particles which is used in the heating device of the body comprises, for example, a metal oxide such as a ferros-ferric oxide, manganese dioxide, etc., carbon, filings or iron powder, etc., as main constituents, in a predetermined ratio for the combination of these. It is known that such a particulate exothermic substance is heated by the chemical reaction upon absorption of air and moisture entering from the outside through an air permeable bag.

The advantageous characteristic of the present invention resides in a mixture of the exothermic substance above described with a fibrous solid residue of agricultural origin impregnated with sodium chloride, magnesium sulphate or a composite salt.

The solid fibrous waste of agricultural origin thus mixed consists, for example, of the residual substance or substances extracted or wrung out in a factory processing an agricultural product or products which are in the form of fibers such as the pulp or beet waste resulting from sugar extraction, bagasse wrung after extraction of the sugar cane juice, or straws, etc.

The fibrous solid material of agricultural origin thus obtained is then immersed in sodium chloride such as cooking salt, magnesium sulphate or a composite salt dissolved in aqueous solution, preferably in a content of 10% by weight, to absorb the solution, and is used as is or after extracting the excess water content if necessary.

 The solid fibrous waste of agricultural origin slows down the brutal exothermic reaction of the mixture and moreover brings its capacity of storage and restitution of heat.

The sodium chloride impregnated in the solid fibrous waste of agricultural origin acts to absorb the humidity coming from the outside and to gradually supply this moisture absorbed through the solid fibrous waste of agricultural origin to the reaction system. Consequently, the heating device for the human body of the present invention thus comprising a solid fibrous waste of agricultural origin impregnated with sodium chloride or the like can provide continuous heating to a suitable temperature for an extremely long time.

The bag intended to receive the particulate exothermic substance and the solid fibrous waste of agricultural origin mentioned above must have air permeability so as to absorb from the outside the necessary humidity and air. The bag is formed for example from Japanese paper, non-woven fabric or the like or from paper
Japan, non-woven fabric and woven or knitted fabric, partially or fully laminated on their back surface with a film of resin or the like and perforated with fine pores.

A preferred example of the composition intended to fill the bag comprises in parts by weight 20 parts of ferros-ferric oxide 25 parts of manganese dioxide 5 parts of magnesium oxide 2 parts of holmium oxide; 4 parts of sodium chloride; 2 to 15 parts, preferably 5 parts of beet pulp 1 part of boron oxide 3 parts of perlite 5 parts of carbon; and, 40 parts of iron filings or powder.

The purpose of the boron oxide in the above composition is to gradually solidify the particulate exothermic substance when the exothermic reaction develops and, moreover, to react with the alkali released from human skin to soften the skin.

A preferred example of the composition may also comprise a mixture of methyl salicylate so as to sub-fold the human muscle by penetration into the skin during the exothermic reaction of the particulate exothermic substance.

Referring now to the figure which illustrates a mode
preferred embodiment of the heating device
for the body produced in accordance with the present invention,
the body heater contains a com
position 1 consisting of a gone exothermic substance
ring including a metal oxide, carbon, etc., and
solid fibrous agricultural waste impregnated with
sodium chloride or the like, and a bag 3 having
fine pores 2 which is filled with composition 1.

It should be noted that the metal oxide is not, preferably
rence, mixed with the other constituents when
introduce the compositions into bag 3. bag 3 as well
filled with the composition, it is also vacuum-sealed
in a bag 4 forming an envelope which is constituted by a
high molecular weight film or the like which is not
permeable to fluids and air. Since the
heating for the body thus sealed
in the envelope bag 4 is isolated from air and
external humidity, the exothermic reaction does not occur
not and it can be stored for a long time.

When this body heater is used,
the envelope bag 4 is torn and the device
heating the body that is inside as well
exposed is shaken as necessary to mix sufficiently
the constituent products which fill the bag 3
which is then kept in contact with human skin
to gradually heat the human body.

It should be understood from the above description
that when the heater for the body of
the present invention is thus produced and implemented,
it can heat to an effective temperature and in any
security. Although the conventional body heating device excessively heats to approximately 70 to 80pu, which can adversely affect the internal organs of the human body and even pose a danger of skin burns, the device heater for the body of the present invention is effective in treating neuralgia since it maintains approximately 52 to 550C and it can be used for elderly and young people without any risk. It should also be understood that the heater for the body of the present invention can provide continuous heating for an extremely long time when so produced and implemented. While the conventional body heater can only provide heating for approximately 5 to 6 hours, i.e., until the exothermic reaction is complete, the body heater of the present invention can heat continuously for up to approximately 24 hours, thereby avoiding frequent annoying replacement, which can be conveniently done once a day, which is economical. It should also be understood that, since b heater of the body of the present invention does not use copper dioxide, nor any toxic substance, as constituents of the filler and bags in contact with the human body and the skin, there is no danger of pollution during its use and its rejection. It should also be understood that since the body heater of the present invention can heat continuously at a suitable temperature for a long time, it can effectively treat neuralgia or the like, soften human skin because the oxide boron softens human skin and soften human muscle because methyl salicylate can soften human muscle. It should further be understood that since the body heating device of the present invention can be manipulated in a simple manner, it can be suitably used to protect from the cold or for therapeutic purposes for the elderly and the young, either at home, at work, or in the hospital.
