Description

FIELD OF THE INVENTION

The present invention relates to the field of medical devices. More specifically, the present invention is a device which is placed on a joint or limb of the body for treating an area of that joint or limb by applying compression, heat or cold thereto.

BACKGROUND OF THE INVENTION

It is known that applying compression along with either cold or heat to a particular area of the human body can aid recovery. Applying heat can relax muscles, improve joint mobility and promote tissue healing. Cold can be applied to reduce pain, swelling and muscle soreness. Compression manages swelling whilst optimising oxygen and nutrient delivery for faster recovery, and also provides support.

Compression-applying devices exist which simultaneously allow a person to also apply heat or cold to specific areas of the body. Typically such devices are formed from an elasticated sleeve formed from neoprene or the like, where the device will have one or more pockets sewn into the sleeve. Those pockets receive a gel pack of a known type, which has either been stored in a freezer or heated in a microwave oven depending upon whether the user wishes to apply cold or heat to the area in question.

Having pockets sewn into the sleeve forms seams which can cause discomfort and irritation to the user, and the seams can fail after prolonged use. Additionally, having pockets means that the removable gel pads can shift during use, meaning that the pads may not be applying the desired heat or cold to the optimal area. Furthermore, removable pads may get misplaced resulting in the sleeve becoming nothing more than a conventional compression or support sleeve unless additional pads are purchased by the user.

It is an aim of the present invention to obviate or mitigate one or more of the aforementioned disadvantages.

SUMMARY OF THE INVENTION

According to the present invention there is provided a medical device comprising:

an elasticated textile body having at least one opening into which a limb may be inserted; and

at least one textile receptacle welded to the elasticated textile body, the at least one receptacle containing a thermal storage medium.

A “thermal storage medium” is a medium which can receive and store thermal energy by being either heated or cooled.

The at least one textile receptacle may be welded to an internal surface of the body.

The body may comprise an inner textile layer and an outer textile layer, wherein the at least one textile receptacle is welded to the inner textile layer.

The outer textile layer may comprise a polyamide and elastic. The outer textile layer may further comprise wool.

The inner textile layer may comprise cotton. The inner textile layer may further comprise elastic.

The thermal storage medium may be a gel. The gel may comprise water and propylene glycol.

The receptacle may be formed from a polyamide.

The textile body may comprise a waistband adapted to fit around the waist of a wearer.

The textile body may comprise a sleeve which is open at both ends. Alternatively, the textile body may comprise a sleeve which is open at one end and closed at an opposite end.

The device 70 comprises an elasticated textile body 72 having an opening 74 to receive the stump and a closed lower end 76. The body 72 may also be provided with ribbing 78 at one or both ends thereof.

The body is formed from a textile of the same type as described above, and again may comprise an inner textile layer and an outer textile layer as also described above.

A plurality of textile receptacles or bags 77 are provided on an inner surface 73 of the body 72. The receptacles may be formed from nylon or a similar polymeric textile. Contained within each receptacle 77 is a thermal storage medium of the type described above, which can receive and store thermal energy by being either heated or cooled. Each receptacle 77 is welded to the inner surface 73 or inner layer of the body 72, the inner surface again being visible to the outside in FIG. 7. The textiles are preferably welded to one another using one of the methods described above.

In the device of FIG. 7, there are four receptacles 77 attached to the body 72, and these are equidistantly spaced around the body 72. Each receptacle 77 has a generally oblong shape.

When in use, each of the devices shown in FIGS. 1-7 works in substantially the same way. The elasticated body of the device provides support as well as dynamic gradient compression to the targeted area. This manages any swelling and at the same time optimises oxygen and nutrient delivery to the area.

Depending upon whether the device is to deliver heat or cold to the area, it can be heated in a heat source such as a microwave oven or else chilled in a freezer. If the device is heated the thermal storage medium in the receptacle(s) delivers radiating heat to the area, relaxing muscles to improve joint mobility whilst also promoting tissue healing. If the device is chilled the thermal storage medium delivers cold to the area, which reduces pain, swelling and muscle soreness.

By welding the receptacles containing the thermal storage medium to the body of the device, the present invention ensures that there are no seams present, thus avoiding discomfort and irritation to the user. Additionally, given that the receptacles are permanently welded to the body means that the thermal storage medium is optimally positioned to treat the muscle groups, ligaments and tendons of a given area of the body, with no risk that the medium can shift position during use. Furthermore, the medium cannot get misplaced.

The receptacles used to house the thermal storage medium may be circular, oblong or tapered, where one end is narrower than an opposite end. The receptacles may also be kidney-, keyhole- or teardrop-shaped. The receptacles may have at least one aperture extending through the receptacle, in the manner described above in relation to the knee treatment device.

Instead of the preferred thermal storage media described above, the present invention may instead use clay, beads or gel pearls as the thermal storage medium.

Whilst it is preferred that each receptacle is welded to an internal surface of the body, it is also possible to weld each receptacle to an outer surface of the body in particular applications.

Whilst it is preferred that the primary component of the body is a polyamide, other polymeric compounds may also be used instead such as, for example, polyacrylonitrile (PAN) or polyvinyl chloride (PVC).

The body of each device may be formed using a circular or flat knitting technique.

Modifications and improvements may be incorporated without departing from the scope of the present invention.
