FIELD OF THE INVENTION

This invention relates to a healthcare instrument for sauna at room temperature and local irradiation treatment.

BACKGROUND OF THE INVENTION

Sauna in sauna room, though it has many advantages, has a drawback that the parts of a human body such as head and testicle are also heated, which is not desirable.

The devices such as far-infrared abdomen band, knee band and the like, being attached onto local parts of a human body to apply heat just thereto, cannot provide an instant and evident local irradiation treatment effect and particularly a sauna effect which draws out the harmful substances with sweat from a human body, because their radiation power and directivity are considerably low. Also, many other known far-infrared devices have not so high radiation power and directivity to obtain said effects. If you raise their temperature to increase the radiation power, then those will emit some near-infrared rays too, which is the reason for thermal stimulation contracting skin and capillary vessels and thereby resulting in illness, so it is impossible to obtain an effective local irradiation treatment effect.

Meanwhile, a far-infrared radiation generator disclosed in CN1878525 P and PCT/KP2004/000003(W02005060355 A2) has high emissivity and directivity of radiation without any thermal stimulation and accordingly enables to obtain a sufficient sauna effect and an instant and evident local irradiation treatment one, but it is a little heavy in weight, complex in structure and low in mechanical and thermal safety in case of using it as a household instrument because it is mainly for sauna room,

Also, with this generator it is impossible to irradiate any necessary parts of a human body in comfortable positions of sitting or lying down in any room situation and to change irradiation direction and distance easily.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a household healthcare instrument; having high emissivity and directivity of radiation without any thermal stimulation and accordingly capable of sufficient sauna even at a room temperature and instant and evident local irradiation treatment; being light in weight and high in mechanical and thermal safety; and capable of irradiating any necessary parts of a human body in comfortable positions of sitting or lying down and controlling irradiation direction and distance easily.

To achieve this object, the present invention has made some changes and improvement to the far- infrared radiation generator disclosed in CN 1878525 P and PCT/KP2004/000003 to overcome its aforementioned drawbacks and employed the resulted improved one.

The healthcare instrument for sauna at room temperature and local irradiation treatment according to the present invention includes a far-infrared radiation generator, a generator-holding arm and a supporting stand.

The generator-holding arm is engaged with the generator by separable hinges and with the supporting stand in a way of insertion, so that those of all can be separated from each other if necessary.

The generator comprises far-infrared emitting panel(s), box-shaped emitting panel containers) made of inflated vermiculite and having an opened (front) side, the radiation breaking sheet(s), an outer box with an opened (front) side and a protective lattice fixed at the front side of the outer box.

The emitting panel is fixed in the emitting panel container by the fixing element such as screw and is spaced from the inner back face of the container by the ledge forming around the inner face of the container, the metallic radiation breaking sheet being inserted into the said spacing. And, one or more said containers containing the emitting panel and the radiation breaking sheet are fixed to the outer box by the fixing element such as screw. The protective lattice has the form of cover and is mounted by hooking means to be easily detached or replaced.

The generator-holding arm is engaged with a side edge of the outer box of the generator by separable hinges.

The supporting stand comprises a base having wheels at its bottom, a main post having a longitudinal hollow therein and standing vertically on the base, a sliding post being inserted into the said hollow of the main post and moving up and down to control its height, and a couple of horizontal bars attached to the top of the sliding post. The generator-holding arm is engaged with the supporting stand in the way of inserting the arm between the said horizontal bars which are parallel to each other and distanced vertically and horizontally from each other to maintain the inserted arm horizontally.

The arm can be inserted upside down so that the generator linked therewith can be hung down vertically or maintained horizontally accordingly. The generator-holding arm together with the generator linked therewith can be pulled out from the supporting stand and fixed to other supporting means such as chair and wall by separable hinges which optionally are attached to the edge of the arm towards the supporting stand.

Also, the generator can be separated from the generator-holding arm and laid down on the floor by short supporting legs on the back face of the outer box in order to irradiate the soles, but then as protective lattice there should be mounted a nonmetal lattice for sole irradiation which can sustain the feet laid down thereon.

The lattice for sole irradiation comprises a lattice frame and rollers in the form of cylinder, wherein each roller can revolve around its central axis with its both ends inserted into the lattice frame when the feet move thereon, and has a lot of protrusions on its surface for stimulation to the soles. Two sides of the lattice frame can be detached so that the rollers can be taken out of the lattice frame and replaced.

The healthcare instrument according to the present invention has the following advantages:

- You can obtain a sauna effect even at a room temperature and an instant and evident local irradiation one too.

- It is particularly useful for those who feel some difficult in sauna room such as the old, the patients suffering from circulatory diseases and the cripples because it has no such aftereffects as that in sauna room.

- You can irradiate any necessary parts of your body in comfortable positions of sitting or lying down and change the irradiation direction and distance easily.

DETAILED DESCRIPTION OF THE INVENTION The embodiments of the healthcare instrument will be described in detail, making particular reference to the enclosed figures.

FIG. 1 shows an embodiment of the healthcare instrument according to the present invention, including a far-infrared radiation generator 1, a generator-holding arm 2 and a supporting stand 3, wherein the generator-holding arm 2 is engaged with the generator 1 by separable hinges 19 and with the supporting stand 3 in a way of insertion.

In the generator 1, a far-infrared emitting panel 4 is fixed in a box-shaped emitting panel container 5 made of inflated vermiculite, and the container 5 is fixed in an outer box 7, wherein the container 5 and the outer box 7 are opened at their front sides respectively to expose the front face of the emitting panel 4, a protective lattice 8 being fixed at the said opened front side of the outer box 7.

The emitting panel 4 is fixed in the emitting panel container 5 by three or five fixer-nails 9 driven into inner sides of the container 5 providing the spacing from the inner back face thereof by the ledge formed along the edges of the back face. And, the radiation breaking sheet 6 is inserted into the said spacing, being folded at its edges orthogonally to provide a distance to the emitting panel 4.

The emitting panel container 5 is fixedly secured into the outer box 7 by means of the screws 10 driven through the back wall of the outer box 7, the back wall of the container 5 and the radiation breaking sheet 6 in turn from outside of the outer box 7.

FIG. 3 shows another embodiment of the healthcare instrument.

This embodiment used a duplex generator having two containers 5 each of which has its own emitting panel 4 and radiation breaking sheet 6 therein respectively and the same structure as above, and just having a double-sized outer box.

In this embodiment, as shown in FIG. 3, the generator can be mounted in different directions.

The protective lattice 8 in the form of cover is fixed by the hooking element.

The generator-holding arm 2, being a rectangle-shaped frame, is engaged at one of its edges with a side edge of the outer box 7 of the generator 1 by separable hinges 19, as shown in FIG. 1.

The supporting stand 3, as shown in FIG. 1, comprises a H-shaped base 11 having four wheels at its bottom, a main post 12 having a longitudinal hollow therein and standing vertically on the base 11, a sliding post 13 being inserted into the said hollow of the main post 12 and moving up and down to control its height, and a couple of horizontal bars 14 attached to the top of the sliding post 13, wherein both of the main and sliding posts 12, 13 have a number of holes therein arranged at regular intervals, so that the sliding post 13 can be fixed at a certain height by inserting a pin into one of the said holes. The generator-holding arm 2 with the generator 1 linked therewith is engaged with the supporting stand 3 in the way of inserting the arm 2 between said horizontal bars 14 which are parallel to each other and distanced vertically as much as the width of the arm 2 and horizontally about as much as 1/3 of the length of the arm 2 from each other to maintain the inserted arm 2 horizontally.

The arm 2 can be inserted upside down so that the hinges 19 linking the arm 2 with the generator 1 are turned over too, accordingly the generator 1 can be hung down vertically (FIG. 1A) or maintained horizontally (FIG. IB). In this way a user can irradiate any necessary parts of his body horizontally or vertically downward sitting on a chair or lying on a bed. Additionally, the generator-holding arm 2 together with the generator 1 linked therewith can be pulled out from the supporting stand 3 and, as shown in FIG. 4, fixed to other supporting means such as chair and wall by separable hinges which optionally are attached to an edge of the arm 2 towards the supporting stand 3.

To use the healthcare instrument for sole irradiation, the generator 1 is separated from the generator-holding arm 2 and laid down on the floor, but then as protective lattice, as seen in FIG. 5, is mounted a wooden lattice for sole irradiation 16 which can sustain the feet laid down thereon.

In FIG.5, the lattice for sole irradiation 16 comprises a lattice frame 17 and rollers 18 in the form of cylinder arranged in two rows, wherein each roller 18 has a central axis therein with its both ends inserted into the lattice frame 17 so that the roller 18 can revolve around the axis. And, the roller 18 has a lot of protrusions on its surface for stimulation to the soles. Two sides of the lattice frame 17 are made respectively and engaged to a main middle frame by screws, so that the sides can be detached and the rollers 18 can be taken out of the lattice frame 17 to be cleaned up or replaced.
