for purposes of illustration , a preferred embodiment of the present invention has been depicted as a pain relieving device 10 for massaging the body 12 of a person 14 . the back pain relieving device 10 generally includes a suction cup 16 mounted to a handle 18 . the suction cup 16 includes a round , flexible , resilient concave disc 20 of either plastic or rubber - like material . the disc is preferably between 4 to 6 inches in maximum diameter , such that one half of a person &# 39 ; s back can be worked on at one time , however it will be readily apparent that all sizes of suction cups may be employed in accordance with the teachings of the present invention . it will also be recognized that the pain relieving device can be used on all area &# 39 ; s of a person &# 39 ; s body , although the figures depicts its use on the back of a person . the outer peripheral edge 22 of the suction cup 16 is adapted to form a seal against a slightly curved or flat skin surface such as that on the back 12 of the person 14 . the suction cup 16 includes a stem portion 26 at the apex 24 of the disc 20 that mounts or is otherwise connected directly to the end of the handle 18 in a removable or permanent manner . the suction cup 16 defines a concave pressure chamber 28 between the apex 24 and the peripheral edge 22 . when a seal is formed at the peripheral edge 22 by applying it to the surface of the body 12 , the action of pushing , rolling and pulling the suction cup 16 effects a change of pressure in the pressure chamber 28 , which in turn massages the back of the person 14 . in particular the suction or pressure caused by the suction cup 16 tends to push , pull and move the muscles around which alleviates back discomfort , soreness and back pain . in the preferred embodiment , the handle 18 includes an axially extending v - shape portion 30 with two v - shaped arms 31 that connects with the stem portion 26 of the suction cup 16 and a transverse hand grip 32 extending in a lateral plane ( eg . generally parallel with the plane of the seal formed by the peripheral edge 22 ). the hand grip 32 is adapted to be manipulated and gripped by the hand 34 of the massager 36 . the hand grip 32 allows the massagers 36 to easily push , pull , roll , and rotate the suction cup 16 to facilitate the massaging action . the lateral orientation of the hand grip 32 allows easy manipulation of the device to facilitate this action . the v - shaped arms 31 allow a person to easily grab the grip 32 between arms . it will be appreciated that a t - shaped handle could also be used . the handle 32 is preferably integrally formed such as from plastic material and is sufficiently rigid and certainly more rigid than the suction cup 16 so that it can adequately impart movement in the suction cup to effect body manipulation and pain relief . using the massaging device 20 is simple , effective and safe . safety is achieved because air pressure is being used to effect the massage . according the preferred method of use , the suction cup 16 is first heated , by such means as dipping it in a container of warm water 38 . the heat tends to soothe the body 12 as well . then the suction cup 16 is applied using the handle 18 . the hand grip 32 is then manipulated to move the suction cup 16 and more particularly push , pull , rotate , and roll the suction cup 16 to effect pressure changes in the pressure chamber 28 and thereby effect the massage . turning attention to fig8 another embodiment of the pain relieving device 10 ′ is depicted . common parts of the pain relieving devices 10 ′ and 10 have been given common reference numerals . the pain relieving device 10 ′ generally includes a suction cup 16 mounted to a handle 18 ′. the suction cup 16 is substantially identical to the suction cup of the prior embodiment . the suction cup 16 again includes a resilient concave disc defining a central axis 38 , which in the figure is generally vertically disposed . the handle 18 ′ in the current embodiment is different , and the alternate handle 18 ′ has proven very useful in practice for providing effective massage . the handle 18 ′ is generally an angled l - shaped member , akin to the shape of a question mark . the handle 18 ′ includes a tubular body 30 ′ which extends upwardly from the suction cup 16 . the tubular body 30 ′ may be either of hollow or solid construction . the tubular member 30 ′ includes an angled portion extending upwardly and outwardly from the apex 24 , and more specifically extends laterally or radially outward relative to the central axis 38 of the suction cup 16 . the tubular member 30 ′ then includes another bend disposing the free end portion of the tubular member 30 ′ generally horizontally or laterally . stated another way , the free end of the tubular member 30 ′ extends generally perpendicular to the central axis 38 . the free end also includes a grip 32 ′ which is laterally or radially centered above the apex 24 of the suction cup 16 and along the central axis 38 . preferably , the tubular member 30 ′ is about ⅞ “ in diameter and positions the grip 32 ′ approximately 13 inches above the surface to which the suction cup 16 is applied . yet another embodiment of the pain relieving device 10 ” is depicted in fig9 . this cross - sectional view is akin to fig7 and depicts a suction cup 16 which has been depicted in a position applied to the surface of the back 12 of a person 14 . while similar to the previous embodiments , the current embodiment of the pain relieving device 10 ′ includes a vacuum or pump system operatively connected to the suction cup 16 , and more particularly a pump 44 operatively connected to the pressure chamber 28 within the suction cup 16 . the terms pump system and vacuum system ( and pump / vacuum ) are used interchangeably herein , and refer to systems which are capable of displacing air . it will be recognized that different persons will require different levels of internal pressure , i . e . forming a relative vacuum inside the chamber 28 and generating a suction effect , to effectively manipulate and massage the back 12 . accordingly , a tube 42 is sealingly connected to the suction cup 16 , preferably adjacent the apex 24 via the stem 26 ″. as the suction cup 16 is constructed of either plastic or rubber - like material , the stem 26 ″ will adequately seal to the outer surface of the tube 42 . however , it will be recognized by those having skill in the art that the inner surface of the stem 26 ″ may include sealing rings , either integrally formed or separately provided , or other seals , seal mechanisms or deflectable projections which provide a seal between the suction cup 16 and the tube 42 . the other end of the tube 42 is properly connected to the pump 44 to provide communication between the pump and the pressure chamber 28 formed between the r suction cup 16 and a person &# 39 ; s back 12 . the pump / vacuum 44 may either be powered or manually operated . it will be readily recognized that the tubular member 42 may actually comprise the handle 18 ″ of the pain relieving device 10 ″. in this way , all that is needed is a hollow tubular handle 18 ″ forming an interior passageway , an inlet of which is operatively connected to the pressure chamber 28 , while an outlet of the internal passage is operatively connected to a pump 44 . a second flexible hose line or tube ( not shown ) may be connected to the handle 18 ″, preferably adjacent the free distal end of the handle 18 ′ proximate the grip 32 ′, such as in the embodiment of the pain relieving device 10 ′ depicted in fig8 . it will also be readily recognized that the pump 44 may be operatively connected to the pressure chamber 28 directly ( and not via the handle ), or via a small hose communicating with the pressure chamber 28 at any other position along the suction cup 16 . in short , the present invention envisions operatively connecting the pressure chamber 28 to a pump 44 , which can be done through the handle 18 , or which may be otherwise directly connected . the pump 44 itself may be remotely provided with an additional tubular extension linking the pump 44 and the interior chamber 28 of the suction cup 16 , preferably by way of the handle 18 ″. alternatively , the pump 44 may be mounted directly to the pain relieving device , preferably to some portion of the handle so as not to disrupt the function of the suction cup . the method of using the present embodiment of the pain relieving device 10 ″ is identical in many respects to the methods previously described for the other embodiments of the pain relieving device . however , by way of the pump 44 , greater control over the pressure or suction effect within the chamber 28 is now achieved . the pump may operate to modulate the suction effect , which itself may provide some therapeutic effect . for example , certain rhythms or frequencies may prove beneficial for alleviating pain . pressure sensors and control systems can also be envisioned for finer control over the pressure or suction effect , such as by way of a closed loop feedback system . a pressure sensor can form part of the pump itself , or be individually supplied , preferably fed through the tube connecting the pump and pressure chamber of the suction cup . the foregoing description of various preferred embodiments of the invention has been presented for purposes of illustration and description . it is not intended to be exhaustive or to limit the invention to the precise forms disclosed . obvious modifications or variations are possible in light of the above teachings . the embodiments discussed were chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated . all such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly , legally , and equitably entitled .
