Description

A MASSAGING DEVICE

Field

[0001 ] The present invention relates to a massaging device for a limb.

[0002] The present invention has been developed primarily for use in massaging a leg. However, it will be apprec iated that the inventi on is not limited to this particular field of use and is also suitable for massaging an arm.

Background

[0003] As blood in the veins of a limb (e.g. leg or arm) generally flows in an upward direction (i.e. against gravity) back to the heart, mechanical forces from the movement of surrounding muscles are required to assist with the blood flow. Similarly, the lymphatic system in the limb also requires movement of surrounding muscles to assist with the movement, of the lymphatic fluid towards the torso. However, sitting or standing still for extended periods of time (e.g.

during airplane or bus travel) can allow blood and lymphatic fluid to pool in the limb and thus increase the risk of developing health issues such as deep vein/venous thrombosis (DVT) and edema.

[0004] In an attempt to prevent the development of D VT and/or edema during extended periods of non-movement, c ompression hosieries are worn. Compression hosieries are designed to exert a substantially static pressure onto parts or all of the legs such that circulation of blood/lymphatic fluid is promoted.

[0005] However, there are questions as to the efficacy of compression hosieries in promoting blood/lymphatic fluid circulation and consequently preventing the development of DVT and/or edema. Moreover, the improper use of these compression hosieries can sometimes lead to other complications such as pressure ulcers, arterial occlusion and gangrene. Further, compression hosieries are often quite difficult to wear, requiring substantial force to pull them into proper position on the leg(s). Still further, compression hosieries often lose their ability to compress after extensive use. Object of invention

[0006] It is the object of tlie present invention to substantially overcome or at least ameliorate one or more of the above disadvantages, or at least provide a useful alternative.

[00031] Figure 5 is a top view of the case of Figure 4. Description of Embodiments

[00032] Fig ares 1 and 2 show an embodiment of a massaging device 10 for a leg of a person. The massaging device 10 includes a flexible fabric garment 12 configured to be worn around the calf of the leg. The garment 12 is substantially rectangular in shape and is defined by two ends 16, 18 and two longi tiidmal sides 20, 22. A plurality of hooks (not shown) are located on the end 16 and a plural ity of corresponding loops ( not shown) are located on the end 18. The hooks and loops are configured to removable engage each other such that the garment 12 is able to substantially wrap around the calf for removable attachment and securing thereto.

[00033] The garment 12 includes four inflatable elongate bladders 24, 26, 28, 30 that are positioned in series between the sides 20, 22 and substantially parallel to each other. Each of the bladders 24, 26, 28, 30 extends between the sides 20, 22 and is substantially adjacent to at least another bladder 24, 26, 28, 30. Each of the bladders 24, 26, 28, 30 is configured to inflate when pressurised air is received therein. Each of the bladders 24, 26, 28, 30 is formed from flat rubber such that they are substantially flat when deflated and ha ve a radius of at least 2.54 cm when inflated.

[00034] The massaging device 1.0 further includes an electrical system 32, a battery 34 for powering the electrical system 32, and an 'On/Off switch 36 to control whether the battery 34 powers the electrical system 32. The electrical system 32 comprises a pressuriser and a controller. The pressuriser is in the form of an electronically powered air pump 38 for supplying pressurised air. The controller is in the form an electronic timer 40 and a sequential pressure distributor 42. The distributor 42 is an electromechanical valve mechanism connected to the air pump 38 and configured to sequentially and repeatedly connect the air pump 38 to each of the bladders 24, 26, 28, 30 via tubing 44 in the following order:

1. bladder 24;

2. bladder 26;

3. bladder 28; and then

4. bladder 30.

[00035] The timer 40 is confi gured to repeatedly measure a predetermined amount of time varying between 1.0 to 45 seconds and send a signal to the distributor 38 each instance the predetermined amount of time is measured. The distributor 42 is configured to connect the air pump 38 to the bladder 24, 26, 28, 30 next in the sequence when the signal, is received from the timer 40. During the connection between the air pump 38 and the bladder 24, 26, 28, 30 next in the sequence, the distributor 42 is further configured to connect the previously connected bladder 24, 26, 28, 30 to the outside environment,

[00036] A typical use and operation of the massaging devi ce 10 wi.ll now be described.

[00037] The garment 12 is wrapped around the calf of the leg such that the bladders 24, 26, 28, 30 are arranged in series between the distal and proximal ends of t he leg, the bladder 24 being the distal -most bladder and the bladder 30 being the proximal-most bladder. Each of the bladders 24, 26, 28, 30 substantially surrounds a respective portion of the calf. The hooks and loops are then engaged with each other such that the garment 12 is removably attached and secured to the calf. Then the switch 36 is switched on such that the battery 34 powers the electrical system 32.

[00038] Upon the electrical system 32 being powered, the distributor 42 connects the air pump 38 to the bladder 24 such that pressurised air is supplied to the bladder 24 for inflation. The inflati on of the bladder 24 causes a pressure to be exerted onto the portion of the calf su rrounded by the bladder 24.

[00039] When the timer 40 measures the predetermined amount of time, a signal is sent to the distributor 42. Upon receiving the signal, the distributor 42 starts to connect the air pump 38 to the bladder 26. During this connection, the distributor 42 connects the bladder 24 to the outside en vironment such that the pressurised fluid irt the bladder 24 is released for deflation. The deflation of the bladder 24 removes the pressure exerted onto the portion of the calf surrounded by the bladder 24. When the connection between the air pump 38 and the bladder 26 is made, pressurised air is supplied to the bladder 26 for inflation. The inflation of the bladder 26 causes a pressure to be exerted onto the portion of the calf surrounded by the bladder 26.

[00040] When the timer 40 again measures the predetermined amount of time, a signal is sent to the distributor 42. Upon receiving the signal, the distributor 42 starts to connect the air pump 38 to the bladder 28. During this connection, the distributor 42 connects the bladder 26 to the outside environment such that the pressurised fluid in the bladder 26 is released for deflation. The deflation of the bladder 26 removes the pressure exerted onto the portion of the calf surrounded by the bladder 26. When the connection between the air purap 38 and the bladder 28 is made, pressurised air is supplied to the bladder 28 for inflation. The inflation of the bladder 28 causes a pressure to be exerted onto the portion of the calf surrounded by the bladder 28.

[00041] When the timer 40 again measures the predetermined amount of time, a signal is sent to the distributor 42. Upon receiving the signal, the distributor 42 starts to connect the air pump 38 to the bladder 30. During this connection, the distributor 42 connects the bladder 28 to the outside environment such that the pressurised fluid in the bladder 28 is released for deflation. The deflation of the bladder 28 removes the pressure exerted onto the portion of the calf surrounded by the bladder 28. When the connection between the air pump 38 and the bladder 30 is made, pressurised air is supplied to the bladder 30 for inflation. The inflation of the bladder 30 causes a pressure to be exerted onto the portion of the calf surrounded by the bladder 30.

[00042] When the timer 40 again measures the predetermined amount of time, a signal is sent to the distributor 42. Upon receiving the signal, the distributor 42 starts to connect the air pump 38 to the bladder 24. During this connection, the distributor 42 connects the bladder 30 to the outside environment such that the pressurised fluid in the bladder 30 is released for deflation. The deflation of the bladder 30 removes the pressure exerted onto the portion of the calf surrounded by the bladder 30. When the connection between the air pump 38 and the bladder 24 is made, pressurised air is supplied to the bladder 24 for inflation. The inflation of the bladder 24 causes a pressure to be exerted onto the portion, of the calf surrounded by the bladder 24.

[00043] The above sequence of inflation and deflation of the bladders 24, 26, 28, 30 will continuously be repeated until the switch 36 is switched off such that the electrical system 32 is no longer powered. During the above sequence, it will be appreciated that the pressures exerted onto the portions of the calf will simulate a pressure wave moving towards the proximal end of the leg that is repeatedly exerted onto the calf It will, also be appreciated that the controller is configured to re-start the above sequence of inflation and deflation of the bladders 24, 26, 28, 30 from the bladder 24 (i.e. the distal-most bladder) whenever the electrical system 32 is powered off and then powered on again. [00044] An advantage of the massaging device 10 is that the repeating pressure wave promotes blood/lymphatic fluid circulation in the leg by assisting the blood/lymphatic fluid towards the proximal end of the leg (i.e. towards the heart and torso). This is particularly beneficial when attempting to reduce the risk of developing DVT or edema. The massaging device 10 provides and/or enhances a peristaltic action axially along the leg or ami towards the heart and torso.

[00045] Another advantage of the massaging device 1.0 is that it does not apply a constant pressure to the legs. Accordingly, there is a reduced risk of causing other heath complications.

[00046] Other advantages of the massaging device 10 are that it is easy to wear and remove, and that it is portable to carry.

[00047] Figures 3 to 5 show another embodiment of a massaging device 10' in which like reference numerals are used to denote like features to that of the massaging device 10. In thi s embodiment, the massaging device 10' further includes a rigid case 46 configured to house the electrical system 32 and the battery 34 therein. The case 46 has an outer surface 48 which is concaved such that, in use, it can be placed ergonomicaliv against the calf of the leg. As seen in Figures 4 and 5, the case 46 is detachable from the garment 12.

[00048] In this embodiment, the garment 12 has a strap 50 and a strap loop 52. The strap 50 extends from the end 18 and the strap loop 52 is located between the end 16 and the case 46. The plurality of hooks 54 are located on an outer surface of the garment 12 located at the free end of the strap 50. The plurality of corresponding loops 56 are located on an outer surface of the garment 12 between the plurality of hooks 54 and the case 46. it will be appreciated, as the garment 12 is wrapped around the calf of the leg, the strap 50 is pivotally threaded through the strap loop 52 such that the hooks 54 and loops 56 are able to removably engage.

[00049] in tliis embodiment, the garment 12 includes six inflatable elongate bladders (not shown) that are substantially the same as those of bladders 24. 26, 28, 30 and operate in much the same manner.

[00050] In this embodiment, the case 46 has an actuatable button 58 which acts as the 'On/Off switch. Also, the button 58 is configured to allow the user to select how long the massaging device 10' will operate by cycling through predetermined time settings (e.g. 5, 10, and 15 minutes). For example., a first actuation of the button 58 will turn on the massaging device 10' for 5 minutes, a second actuation of the button 58 will turn on the massaging device 10' for 10 minutes, 3 third actuation, of the button 58 will turn on the massaging device 10' for 15 minutes, and a fourth actuation of the button 58 will turn off the massaging device 10'. The electrical system 32 further comprises a series of LED lights 60 viewable through the top of the case 46. The LED lights 60 provide indications of what predetermined time setting has been selected.

[00051] In this embodiment, the electrical system 32 further comprises a micro-US B port 62 which is accessible througli the side of the case 46. The port 62 allows power to be received from an external source (e.g. a computer) to recharge the battery 34. It will also be appreciated that, in other embodiments, the massaging device 10' does not have the battery 34 and instead the port 62 allows power from the external source to directly power the electrical system 32.

[00052] Although the invention has been described with reference to a preferred embodiment, it Will be appreciated by a person skilled in the art that the invention may be embodied in many other forms. For example, in another embodiment, the massaging device 10 may be for an arm of a person.
