One or more embodiments of the invention are related to the field of physical therapy devices. More particularly, but not by way of limitation, one or more embodiments of the invention enable a programmable multi-therapy inversion table.
Inversion tables for spinal decompression are known in the art. Generally these tables are simple mechanical devices that a user manually rotates to position the head lower than the legs in order to stretch the spine. While these devices can be effective, some patients benefit from other kinds of therapies such as traction, massage, or heat. Some devices have added heating pads to inversion tables, but full integration of a wider range of therapies into a single inversion table has not been performed.
An additional limitation of most existing inversion tables is that they are either manually positioned by the user, or if they support electronic control then the user must enter specific settings (for example for the tilt angle of the table). In some situations, users may benefit from time-varying settings that are cycled automatically, which could be accomplished with a programmable inversion table.
For at least the limitations described above there is a need for a programmable multi-therapy inversion table.
One or more embodiments described in the specification are related to a programmable multi-therapy inversion table. Embodiments of the invention may incorporate multiple therapeutic elements into an inversion table and may programmatically control the settings of these elements to execute sequences of therapies.
One or more embodiments of the invention may include a supporting frame, a back rest, and one or more moving back massage elements coupled to the back rest. The back rest may be coupled to the frame so that it can rotate between an upright position with the superior end (closest to the head) vertically higher than the inferior end (closest to the feet), and an inverted position with the superior end vertically lower than the inferior end. The one or more moving back massage elements may each have a back vibrating element that applies vibration to the user's back, and a back massage element position actuator that moves the vibrating element along a track in or coupled to the back rest, in order to position the vibrating element at multiple locations of the user's back.
One or more embodiments of the invention may also have a table tilt actuator that moves the back rest between its upright and inverted positions.
In one or more embodiments, the track along which a back massage element moves may be a slot in the back rest; it may for example extend from a first position closest to the superior end of the back rest to a second position closest to the inferior end.
One or more embodiments may have two moving back massage elements that move in parallel tracks.
In one or more embodiments, each moving back massage element may also be configured to rotate the back vibrating element.
One or more embodiments may include a head and neck support coupled to the back rest. It may include a neck traction actuator that moves the head and neck support away from the back rest.
In one or more embodiments, one or more moving neck massage elements may be coupled to the head and neck support. Each neck massage element may have a neck vibrating element that applies vibration to the user's neck, and a neck massage position actuator that moves the vibrating element along a track in or coupled to the head and neck support, in order to position the vibrating element at multiple locations of the user's neck.
In one or more embodiments, the track associated with a moving neck massage element may be a slot in the head and neck support. The track may extend from a first position closest to the superior end of the head and neck support to a second position closest to the inferior end.
One or more embodiments may have two moving neck massage elements that may move in parallel tracks.
In one or more embodiments, the moving neck massage elements may be further configured to rotate the neck vibrating elements.
One or more embodiments may include a leg support coupled to the back rest. It may include a leg traction actuator that moves the leg support away from the back rest.
One or more embodiments may include a heating pad coupled to the back rest.
One or more embodiments may include a processor that is configured to set or modify one or more of the settings of any of the elements of the inversion table, such as the back rest, the table tilt actuator, the moving back massage element or elements, the moving neck massage element or elements, the neck traction actuator, the leg traction actuator, or the heating pad or pads. One or more embodiments may include a stored program that executes on the processor and that sets or modifies one or more of these settings.
The above and other aspects, features and advantages of the invention will be more apparent from the following more particular description thereof, presented in conjunction with the following drawings wherein:
A programmable multi-therapy inversion table will now be described. In the following exemplary description, numerous specific details are set forth in order to provide a more thorough understanding of embodiments of the invention. It will be apparent, however, to an artisan of ordinary skill that the present invention may be practiced without incorporating all aspects of the specific details described herein. In other instances, specific features, quantities, or measurements well known to those of ordinary skill in the art have not been described in detail so as not to obscure the invention. Readers should note that although examples of the invention are set forth herein, the claims, and the full scope of any equivalents, are what define the metes and bounds of the invention.
Illustrative inversion table 100 has a head and neck support 104 attached to the superior end 103a of back rest 103, and a leg support 105 attached to the inferior end 103b of back rest 103. Head and neck support 104 has a head rest 114 and a chin strap or other head support or brace 113; and leg support 105 has a knee pad 115 and ankle clamps or other foot braces or supports 116a and 116b. These supports may also incorporate additional therapies in one or more embodiments. For example, the supports may be coupled to the back rest via actuators that apply traction. Traction actuators may be located on the back rest or on the head and neck or leg supports. Force may be applied for example to head and neck support 104 to push it in the superior direction, thereby applying traction to the user's neck as chin strap 113 pulls the head away from the back. In one or more embodiments, chin strap 113 may be any brace, strap, or pad that can contact a portion of the user's head to apply a neck traction force. Force may be applied for example to leg support 105 to push it in the inferior direction, thereby applying traction to the user's legs or lower back as ankle clamps 116a and 116b or similar braces pull the feet away from the back. In one or more embodiments, traction may be applied to any body part in any direction.
One or more embodiments may incorporate one or more heating pads or other temperature control elements into any part of the inversion table. For example, inversion table 100 may have a heating pad 106 that covers all or a portion of back rest 103. Heating pads may also be incorporated for example into either or both of the head and neck support 104 and the leg support 105. In one or more embodiments, one or more vibrating elements may also provide heat. The temperature or heat output of any of the heating elements may be controllable.
Inversion table 100 may for example be powered via an electrical connection 121, or via a battery. It may include one or more user control devices such as device 120, which may for example allow the user to modify the settings of any of the therapy elements of the inversion table.
In one or more embodiments, head and neck support 104 may incorporate one or more massage elements to massage for example the neck or the back of the head.
The components of the inversion table may be constructed of any desired materials. For example, the back rest may be made of polyurethane.
One or more embodiments may incorporate leg massage elements into the leg support 105. More generally, embodiments may incorporate any number of massage elements positioned at any location in the inversion table, to target any desired portion or portions of the user's body. These massage elements may be stationary, or they may move. For example,
In one or more embodiments, the inversion table may include or communicate with one or more processors that control the actuators to achieve the desired settings or sequences of settings for the degrees of freedom of the inversion table. For example, a microprocessor 420 may be integrated into the inversion table and connected electrically or wirelessly to the actuators. One or more embodiments may use any type or types of processors for control, including for example, without limitation, a microprocessor, a microcontroller, a customized circuit, an ASIC, a CPU, a GPU, a laptop or desktop or tablet computer, a server, a mobile device, a smart phone, a smart watch, or a network of any of these devices.
In one or more embodiments, the user of the inversion table, or a therapist or assistant, may be able to control some or all of the settings associated with these degrees of freedom. For example, the inversion table may include a controller 120 with buttons or switches to select or modify settings; this controller may communicate with processor 420. In one or more embodiments, a user may use an external device such as a smartphone 421 that executes an application that presents controls to the user, and this device may for example communicate over a wireless channel 422 with processor 420. Any types of controls may be presented to the user; for example, a user may use top-level controls such as buttons 423a through 423d to bring up submenus or detail screens for control of individual therapy elements.
Embodiments may use any type or types of actuators to achieve the desired output and settings of the therapy elements.
In one or more embodiments, the inversion table may include one or more stored programs that cycle the therapy elements through sequences of settings. Programs may for example be selectable or customizable by a user or therapist. One or more embodiments may expose an application programming interface that allows for additional programs to be developed or modified.
Another illustrative program may for example modify the pitch angle of the inversion table over time. For example, one such program may set the pitch angle to −25 degrees for 70 seconds, then set the pitch angle to −35 degrees for 60 seconds, then set the pitch angle to −45 degrees for 50 seconds, then set the pitch angle to −55 degrees for 40 seconds, and then set the pitch angle to −65 degrees for 30 seconds. This program is illustrative; one or more embodiments may modify pitch angle or any other settings over time using any desired patterns.
Illustrative ranges or levels for settings of various elements of an illustrative embodiment of the invention are shown in the tables below. These values are illustrative and embodiments may modify or extend these levels and ranges as desired or required.
