Description

THERAPEUTIC WEARABLE ARTICLE

FIELD OF THE DISCLOSURE

The present disclosure relates to therapeutic device, in particular to a therapeutic wearable article for delivering an electric pulse to a user.

BACKGROUND

Conventionally, infirmities have been treated through various means including oral or local medications, physical therapy, chiropractic manipulation and surgery. Apart from these conventional ways, transcutaneous electrical nerve stimulation (TENS) and Electrical Muscle Stimulation (EMS) are the widely used nonpharmacologic and noninvasive treatments for pain. TENS and EMS reduce pain through activating sites in spinal cord and brainstem that utilize opioid, serotonin, and muscarinic receptors or by activating opioid and a-2 noradrenergic receptors at sites. In TENS and EMS, electric pulses are applied at the required sites using multiple electrode patches made of conductive sponge, rubber or elastomers. In rare cases, a layer of woven metal mesh material is used as an electrode to deliver the pulses to a treatment site. Such mesh material is formed into different wearable products such as glove, sock, sleeve and the like, so that it is easy to attach the electrode to the user.

United States Patent Publication no.: US 2002/0077689 A1 discloses an elastomeric garment holding pre-positioned electrodes for EMS/TENS users. The electrodes are interconnected by wires routed through seams in the suit. A color- coded connection between output terminals of a stimulation device and an interface connector enables selectively directing the pulses to one or more electrodes to thereby target specific muscle groups of the user. However, delivering pulses of opposite polarities to adjacently positioned electrodes, especially for joints, needs a highly complicated wiring arrangement. There is therefore a need in the art for a device for delivering an electric pulse to a user, which is simple in arrangement and effective in delivering pulses to complex body parts without a need for an expert.

SUMMARY

The present disclosure proposes a therapeutic wearable article and method for delivering an electric pulse to a treatment site of a user. The article comprises a flexible body formed of a flexible material and wearable around the site. Two sets of electrical conductor pads are attached to the body, such that the pads come in contact with the site when the article is in use. Two connector elements are attached to the body for connecting to a pulse generator through cables. An electric circuit is embedded within the body for connecting the connector elements to the corresponding conductor pads.

In one aspect of the present invention, the electric circuit includes two electrically conductive elements isolated from each other, wherein a first electrically conductive element connects a first connector element to a first set of electrical conductor pads, and a second electrically conductive element connects a second connector element to a second set of electrical conductor pads. When the body is worn by the user, the conductor pads are aligned with respect to the site such that each conductor pad is positioned adjacent an oppositely polarized conductor pad. The first connector element is connected to a positive terminal of the pulse generator and the second connector element is connected to a negative terminal of the pulse generator.

In a preferred embodiment when the body is worn around a knee joint, four conductor pads are aligned around an anterior portion of the knee joint, while two conductor pads are aligned against a posterior portion of the knee joint. As the conductor pads are attached to the body, there no need for an expert to position the pads on the site. Further, the opposite polarities of adjacent pads allow stimulation of complex body parts i.e. joints, with higher accuracy without a need for sophisticated wiring arrangements.

Referring to the accompanying drawings, FIG. 1 illustrates diagrammatic rear view of the article for delivering an electric pulse, in accordance with an exemplary embodiment of the present invention. The article (100) comprises a flexible body (101 ) formed of a flexible material and wearable by a user. In a preferred embodiment, the body (101 ) is formed as an X-shaped brace to be worn around the user’s knee joint. The flexible material can include but not limited to fabric, plastic, rubber or any other flexible electrically insulative material. Two ends of the body (101 ) are attached with first fastening elements (105a) at a rear side, while opposite ends of the body (101 ) are attached with second fastening elements (105b, shown in FIG. 2) at a front side for mating with the corresponding first fastening elements to secure the body (101 ) against the knee joint (as shown in FIGs. 3A - 3C). The fastening elements (105a, 105b) may include but not limited to hook and loop fasteners, push button fasteners, belt fasteners, adhesive fasteners and the like.

A plurality of electrical conductor pads (102a - 102f) is attached to a rear side of the body (101 ) to be in contact with the knee joint when the article (100) is in use. The conductor pads (102a - 102f) are made of an electrically conductive material such as metal, metallic paint, graphite and conductive rubber or polymer. In a preferred embodiment, the conductor pads (102a - 102f) are made of copper. Similarly, the conductor pads (102a - 102f) are made as circular plates to avoid damaging a skin surface of the user, even though it is possible to form the conductor pads (102a - 102f) in other shapes. Further, the conductor pads (102 a - 102f) may also be formed as suction pads or adhesive gel pads to secure the body (101 ) in position, which avoids a need for the fastening elements (105a, 105b).

Two connector elements (103a, 103b) are attached to the body (101 ) for detachably connecting to a pulse generator (10) through cables (20). The connector elements (103a, 103b) can be any type of commercially available electrical connectors that is capable of establishing a mating connection with corresponding connectors fixed to one end of the cables (20). For example, the connector elements (103a, 103b) may be push in connectors or button type connectors such as battery button connector and the like. Other end of the cables is connected to the pulse generator (10). In a preferred embodiment, the pulse generator (10) is a transcutaneous electrical nerve stimulation (TENS or TNS) machine. Flowever, in an alternate embodiment, the pulse generator (10) may be any commercially available wired or portable electric pulse generator that can be removably attached to the body (101 ) and powered by one or more batteries. Further, the pulse generator (10) may include a wired or wireless remote controller operable by the user to adjust one or more attributes e.g. frequency, shape, magnitude and the like, of the electric pulses. The connector elements (103a, 103b) are attached to a front side of the body (101 ), as shown in FIG. 2.

An electric circuit is embedded within the body (101 ) for connecting the connector elements (103a, 103b) to the corresponding conductor pads (102a - 102f). The electric circuit includes two conductive elements (104a, 104b) electrically isolated from each other. The conductive elements (104a, 104b) may be any commercially available electric wires or metallic strips separated by an insulative material. Further, each conductive element (104a, 104b) may be a single continuous wire or metallic strip or multiple wires or metallic strips connected together through any conventional fastening means e.g. soldering.

A first conductive element (104a) connects a first connector element (103a) to a first set of conductor pads (102a - 102c), and a second conductive element (104b) connects a second connector element (103b) to a second set of conductor pads (102d - 102f). In a preferred embodiment, the first connector element (103a) and the second connector element (103a) are connected to positive terminal (not shown) and negative terminal (not shown) of the pulse generator (10), respectively. In an alternate embodiment, the connector elements (103a, 103b) may be connected to the pulse generator (10) in reverse order.

As shown in FIGs. 3A - 3C, when the body (101 ) is worn by the user, the conductor pads (102a - 102f) are aligned with respect to the treatment site such that each of the conductor pads (102a - 102f) is positioned adjacent one or more oppositely polarized conductor pads (102a - 102f). In a preferred embodiment, when the body (101 ) is worn around the knee joint, four conductor pads (102a, 102c, 102d, 102f) are aligned around an anterior portion of the knee joint, while the two conductor pads (102b, 102e) are aligned against a posterior portion of the knee joint.

The method for delivering an electric pulse to the knee joint using the article (100) is explained in the following description with reference to the FIGs. 3A - 3C. Firstly, the body (101 ) is fastened around the knee joint, wherein the conductor pads (102a and 102f) are positioned above the knee joint, while the conductor pads (102c and 102d) are positioned below the knee joint, as shown in FIG. 3A. Further, the other conductor pads (102b and 102e) are positioned against a posterior portion of the knee joint, as shown in FIG. 3B.

After fastening the body, the connector elements (103a, 103b) are connected to the pulse generator (10) through the cables (20) for receiving the electric pulse, wherein the first connector element (103a) is connected a positive terminal of the pulse generator (10), while the second connector element (103b) is connected a negative terminal of the pulse generator (10). Finally, the electric pulse is delivered to the knee joint through the conductor pads (102a - 102f), when the pulse generator (10) is switched on. Since each connector element (103a, 103b) is connected to the corresponding set of conductor pads (102a - 102c) through a different conductive element (104a, 104b), opposite polarity of the connector elements (103b) results in position each conductor pad (102a - 102f) adjacent to one or more oppositely polarized conductor pads (102a - 102f) when the body (101 ) is worn, as shown in FIGs. 3A & 3B. As the conductor pads (102a - 102f) are attached to the body (101 ), there no need for an expert for positioning the conductor pads (102a - 102f) at appropriate positions on the site. Further, the opposite polarities of adjacent conductor pads (102a - 102f) allow stimulation of complex body parts i.e. joints, with higher accuracy without a need for complicated wiring arrangements.

FIGs 4 - 7 illustrate diagrammatic representations the article, in accordance with an alternate embodiment of the present invention. In this embodiment, the article (100) comprises a flexible body (101 ) formed of two straps 9101 a, 101 b) detachably coupled to each other. Each strap (101 a, 101 b) includes a set of conductor pads (102a - 102f), a connector element (103a, 103b) and one or more fastening elements (105a, 105b).

In addition, the first strap (101 a) includes a pair of slits (106a), and the second strap (101 b) includes a pair of projections (106b). The second strap (101 b) is inserted through one of the slits (106a) and withdrawn through the other slit (106a) for detachably coupling the straps (101 a 101 b), as shown in FIG 6. The slits (106a) are spaced apart, such that one of the conductor pads (102d - 102f) is positioned between the slits (106a), when the straps (101 a, 101 b) are coupled to each other. Further, the projections (106b) are wider than a length of one or both of the slits (106a), and therefore limiting movement of the second strap (101 b) through the corresponding slit (106a).

A conductive element (104a, 104b) is embedded within each strap (101 a, 101 b) for connecting the connector element (103a) attached to the strap (101 a, 101 b) with corresponding conductor pads (102a - 102f). Thus, each conductor pad (102a - 102f) is polarized according to a polarity of the corresponding connector element (103a, 103b), and therefore delivering positive and negative electric pulses at corresponding locations on the site. As the straps (101 a, 101 b) form a crisscrossed structure, when worn by the user, it is possible to deliver positive and negative electric pulses through adjacent conductor pads (102a - 102f) without a need for complex wiring circuit between the conductor pads (102a - 102f) and the corresponding connector elements (103a, 103b). Since the straps (1 10a, 1 10b) are detachably coupled to each other, it is possible to wear the straps (1 10a, 1 10b) separately around different locations of a treatment site, as shown in FIG 7, according to a user’s requirements. In other embodiments, the straps (101 a, 101 b) may also be rotatably coupled to each other through a pivot joint.

In further embodiments, the body (101 ) may be formed with one or more foldable flaps (107) adjacent to each conductor pads (102a - 102f), as shown in FIG. 8. The flaps (107) can be folded as per the user’s requirement to prevent a contact between user’s skin and the corresponding conductor pads (102a - 102f). Thus, the present invention allows increasing or decreasing a number of conductor pads (102a - 102f) during use. Even though the above embodiments show the present invention used for treating knee joint and arm, it may also be used for but not limited to elbow and ankle joints. Additionally, the one or more pairs of fastening means (108) is attached to an inner side of the body (101 ), as shown in FIG. 9, to allow a user to vary a length of the body (101 ) (as shown in FIG. 10) according to the user’s requirements.
