The present invention relates to devices for ice compress, and more particularly to a pressure adjustable structure for ice compress capable of freely varying the gas pressure therein so that the effect of ice compress will be optimized.
Because of its simplicity, easy accessibility and effective medical functions, ice compress, as a means of cryotherapy, is a widely used medical treatment in daily life. Within the first 24 hours after an acute sport hazard, ice compress is used to alleviate pains, restrain inflammations, contract blood vessels, reduce edema and slow down metabolism, so as to cure the hazard.
A conventional means of ice compress uses a plastic bag filled with ice cubes, which will be applied onto a body portion. This method achieves the effect of ice compress on a small area, which is not an effective medical treatment. To achieve a better effect, the method of pressurized ice compress is adopted. It is done by binding the ice bag onto a body portion, such as an arm or a thigh, with a flexible binding strap. However, since the skin of the applied body portion cannot tolerate the low temperature of the ice bag immediately, the binding of the ice bag with the body portion should not be too tight. After a while, the adhesive stress should be increased to get better ice-compress effect.
Referring to
Based on the disadvantages of the prior art, the inventor disclose the present invention for providing improvements.
Accordingly, the primary objective of the present invention is to provide a pressure adjustable structure for ice compress, wherein fine adjustments of gas pressure therein can be done by freely inflating or deflating an air chamber therein. Thereby, the effect of ice compress can be optimized.
To achieve the above object, the present invention provides a pressure adjustable structure for ice compress. The structure comprises an ice-packing unit being substantially a bag filled with a low-temperature preserving gel material; an air-containing unit disposed along the ice-packing unit and substantially covering a surface of the ice-packing unit, the air-containing unit having a hollow air bag and a gas valve installed at a selected location; and a pressure-adjusting unit connected to the gas valve of the air-containing unit, the pressure-adjusting unit further comprising a gas tube, an air pumping unit, and a pressure-releasing unit, the gas tube having one end connected to the gas valve and another end connected to the air pumping unit through the pressure-releasing unit, whereby the air pumping unit will inject air into the air-containing unit and. The pressure-releasing unit will release excessive air in the air-containing unit to bring down the gas pressure therein.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawings.
Referring to
The ice-packing unit 4 is of bag structure, in which low-temperature preserving gel is stuffed. The gel is made of water, sodium, acidic groups, wood spirit, cellulose and pigments.
The air-containing unit 5 is a hollow air bag disposed along the ice-packing unit 4 and substantially covering the surface of the ice-packing unit 4. The air-containing unit 5 further includes a gas valve 51, which is connected to the pressure-adjusting unit 6.
The pressure-adjusting unit 6 comprises a gas tube 61, an air pumping unit 62, and a pressure-releasing unit 63. One end of the gas tube 61 is connected to the gas valve 51, and the other end is connected to the air pumping unit 62 through the pressure-releasing unit 63. As the air pumping unit 62 is squeezed, air is pumped into the air-containing unit 5 through the gas tube 61. As the pressure-releasing unit 63 is rotated or pressed, the air in the gas tube 61 will be released so as to bring the pressure in the air-containing unit 5 down.
The ice-compress body 3 further comprises a net body 31 for confining a hand between the net body 31 and the ice-packing unit 4, as shown in
Another preferred embodiment of the present invention is shown in
To facilitate the folding of the ice-compress body 7, the ice-packing units 75 and the air-containing units 76 are arranged in an interlaced fashion, as shown in
In a larger sense, the present invention is applied not only to ice compress but also to hot compress.
The present invention is thus described, and it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
This application is a continuation-in-part of U.S. patent application Ser. No. 11/031,141, filed on Jan. 10, 2005.
