PAIN-RELIEVING APPARATUS

Abstract

The pain-relieving apparatus has a housing, a stimulating surface, user inputs, and a plurality of ports, such as a battery port and a transcutaneous electrical nerve stimulation (TENS) output connector. The stimulating surface may include a suction ring, vacuum apertures, vibration stimulators, a plate, heat and cold transducer elements, and medicinal holders to provide various approaches for relieving pain. In some examples, the pain-relieving apparatus features a haptic motor that may have a coil frame, a voice coil, a rod, a magnet slidable on the rod, and compression springs on each side of the magnet. As the magnet oscillates, it produces vibrations having waveforms such as sine waves, square waves, triangle waves, sawtooth waves, and related waveforms. A user may adjust the waveform according to whether the pain experienced is acute or chronic in nature and according to personal preference or preloaded settings.

Description

TECHNICAL FIELD

The present disclosure relates to pain relieving devices. More particularly, the present disclosure relates to a pain-relieving apparatus that decreases and/or eliminates pain signals traveling to the brain by using a combination of cooling, heating, vibration, suction, TENS, lidocaine, sound, and video.

BACKGROUND

Since 2016, the opioid crisis in the USA has been responsible for an estimated 50,000 to 72,000 deaths annually due to overdose. This has grown from an estimated 12,000 to 50,000 annual deaths since 2002. This is especially a problem within the United States. In particular, an astounding 80% of the world's pharmaceutical supply is consumed by the U.S. each year. With few alternatives to treating chronic pain, there will continue to be pain-relieving medication abuse and addiction.

The dependence on opioids and other pain-relieving medications have led to several non-medicinal approaches for relieving pain that exist in the art. These approaches use acupuncture, electrical nerve stimulation, heating and cooling devices, vibrational devices, and other methods. However, the plethora of devices, and their unique approaches to pain reduction, make it difficult and expensive to effectively treat pain. In other words, a user may end up paying for several approaches until the preferred approach is discovered. For example, a single approach may use heating and cooling without utilizing the other pain-reducing approaches. This one-dimensional approach to pain relief creates difficulty when addressing chronic pain, because individuals may require unique stimuli, in different forms, that will be optimal for their nerve and sensation needs. Trying to find which stimulation works for them is expensive and time-consuming, which leads to the continued reliance on medication.

Further, after receiving a prescription from a doctor, pain-relieving medication can be easily obtained. In the end, the pain-relieving medication may cause more harm than help, making an individual dependent on medication and, ultimately, addicted. Not only can those that have chronic pain abuse the pain-relieving medication, but youth, or other individuals that live in the same house, may abuse it. In addition, it is felt that combining different modalities together into one device might have an additive effect that will significantly decrease the pain that an individual feels, not only leading to the decreased use of pain medications as well as the ability to use lower amounts of heat, vibration, suction or electrical stimulation used individually.

Accordingly, there is a need to reduce the dependence on opioids and other pain-relieving medications by using a pain-relieving apparatus with multiple functionalities and approaches to pain relief, that is compact, and that is inexpensive. The present disclosure seeks to solve these and other problems.

SUMMARY OF EXAMPLE EMBODIMENTS

In some embodiments, the pain-relieving apparatus comprises a housing, a stimulating surface, user inputs, and a plurality of ports, such as a battery port and a transcutaneous electrical nerve stimulation (“TENS”) output connector. The stimulating surface may comprise a suction ring, vacuum apertures, vibration stimulators, a plate, and medicinal holders to provide various approaches for relieving pain. The pain-relieving apparatus may further comprise a sound speaker for producing nerve stimulating sounds. In some embodiments, the pain-relieving apparatus comprises user inputs through a smartphone application. The smartphone has additional sound and video options for distraction from pain.

In some embodiments, a method of using the pain-relieving apparatus comprises a user placing the pain-relieving apparatus on a painful area of the body via attachment sites. Through user inputs, whether on a smartphone or on the pain-relieving apparatus, the user selects which type of pain control modality to use. The user may use multiple modalities at the same time. The user adjusts the intensity of each modality of pain control from the user inputs. By varying between modalities and intensities, the user is able to find the pain control modality(ies) that best treat the pain. For example, the user may select plate and vacuum apertures to provide heat/cold, vibration, and suction, respectively. The user then determines if the pain control modalities distract the pain stimulus and provide relief. If the modalities do not provide relief, then the user selects other modalities to use, alone or together, to determine the best pain relief option.

In some embodiments, a pain-relieving apparatus comprises a housing, a removably attachable cooling component, user inputs, and medicinal holders. In an alternate embodiment, the pain-relieving apparatus may be a single unit with all components.

In some embodiments, a pain-relieving apparatus comprises a housing, a haptic motor, and vibration stimulators configured to provide therapeutic vibration. The haptic motor may comprise an eccentric rotation mass motor, voice coil actuator, a linear resonant actuator, or other haptic motor. The haptic motor, in some embodiments, may comprise a voice coil, a magnet slidable on a rod and interposed between a first compression spring and a second compression spring, wherein the magnet oscillates between the first and second compression springs when current is supplied to the voice coil, the oscillation creating waveforms. The haptic motor enables a user to change not only the frequency and amplitude of the vibrations, but also the waveform. The waveforms generated may include sine waves, square waves, triangle waves, sawtooth waves, related waveforms, and combinations thereof. In addition, the vibration motor's waveforms, amplitude and frequency can be synced with auditory or visual stimuli, further improving the experience and combined additive effect of the multi-modality device.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

The following descriptions depict only example embodiments and are not to be considered limiting in scope. Any reference herein to “the invention” is not intended to restrict or limit the invention to exact features or steps of any one or more of the exemplary embodiments disclosed in the present specification. References to “one embodiment,” “an embodiment,” “various embodiments,” and the like, may indicate that the embodiment(s) so described may include a particular feature, structure, or characteristic, but not every embodiment necessarily includes the particular feature, structure, or characteristic. Further, repeated use of the phrase “In some embodiments,” or “in an embodiment,” do not necessarily refer to the same embodiment, although they may.

Reference to the drawings is done throughout the disclosure using various numbers. The numbers used are for the convenience of the drafter only and the absence of numbers in an apparent sequence should not be considered limiting and does not imply that additional parts of that particular embodiment exist. Numbering patterns from one embodiment to the other need not imply that each embodiment has similar parts, although it may.

Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the invention, which is to be given the full breadth of the appended claims and any and all equivalents thereof. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation. Unless otherwise expressly defined herein, such terms are intended to be given their broad, ordinary, and customary meaning not inconsistent with that applicable in the relevant industry and without restriction to any specific embodiment hereinafter described. As used herein, the article “a” is intended to include one or more items. When used herein to join a list of items, the term “or” denotes at least one of the items, but does not exclude a plurality of items of the list. For exemplary methods or processes, the sequence and/or arrangement of steps described herein are illustrative and not restrictive.

It should be understood that the steps of any such processes or methods are not limited to being carried out in any particular sequence, arrangement, or with any particular graphics or interface. Indeed, the steps of the disclosed processes or methods generally may be carried out in various sequences and arrangements while still falling within the scope of the present invention.

The term “coupled” may mean that two or more elements are in direct physical contact. However, “coupled” may also mean that two or more elements are not in direct contact with each other, but yet still cooperate or interact with each other.

The terms “comprising,” “including,” “having,” and the like, as used with respect to embodiments, are synonymous, and are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including, but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes, but is not limited to,” etc.).

As previously discussed, there is a need for a pain-relieving apparatus with multiple functionalities and approaches to pain relief, that is compact, inexpensive, and that reduces dependence on medications. The pain-relieving apparatus disclosed herein solves these problems and others.

In general, the pain-relieving apparatus disclosed herein comprises numerous pain relief modalities to decrease and/or eliminate pain. Typically, a user is limited to addressing pain through one or two pain relief modalities, such as heat and cold, or through consuming pain-relieving medication, which may lead to abuse and addiction. In contrast, the pain-relieving apparatus herein may include numerous pain relief modalities to address a user's particular pain in a customizable manner. For example, the pain-relieving apparatus may utilize vibration, cooling, heating, suction, TENS, lidocaine, video, and sound to overload nerve pathways to eliminate pain signals. A user is able to select the pain relief modality that best addresses the pain that is being experienced. That is, the user is able to combine numerous pain relief modalities, at varying levels of intensity, to prevent nerves from sending pain signals to the brain.

In particular, the pain-relieving apparatus is capable of stimulating the projection neuron. Nerves transmit sensory stimuli to the “projection neuron,” which is referred to as signaling. This signaling works well to transmit a single sensory projection. With chronic pain, this neuron is transmitting the signal of pain constantly to the brain. The prior art contains some nerve stimulating mechanisms that interact with the projection neuron. However, the prior art devices have used a combination of only one or two pain control modalities to combat pain, which the efficacy of such devices ranges as many individuals require unique stimuli that is optimal for their nerve and sensation needs. Accordingly, these devices fail to adequately control the user's personalized pain by being limited to using one or two modalities, which forces many users to consume pain-relieving medication. In contrast, the pain-relieving apparatus disclosed herein contains numerous pain control modalities to combat pain, which create a personalized pain relief system for any user and allows for maximum pain relief. Moreover, the user is able to find the right combination for any pain, allowing the user to use the pain-relieving apparatus instead of relying on pain-relieving medication.

In some embodiments, as shown in FIGS. 1-2, the pain-relieving apparatus 100 comprises a housing 102, a stimulating surface 104, user inputs 106, and one or more ports, such as a battery port 108 and a TENS output connector 109. The pain-relieving apparatus 100 may vary in size and shape. For example, the housing 102 may be compact for traveling or larger for at home or institutional use. The housing 102, as shown, may be oval shaped. However, the housing 102 may be other formfactors, such as circular, square, hourglass, etc.

The stimulating surface 104 may comprise a variety of pain control modalities, such as a suction ring 110, vacuum apertures 112, vibration stimulators 114, a plate 116, and medicinal holders 120. While the stimulating surface 104 may comprise numerous pain control modalities, as mentioned above, it will be appreciated that the pain-relieving apparatus 100 can have many, or few, pain control modalities, as well as different types of pain control modalities. For example, in some embodiments, the stimulating surface may be limited to the vibration stimulators 114 and the plate 116. In other words, any variety of modalities may be combined into a single unit.

Referring to FIGS. 3-5, the suction ring 110 segregates the various types of pain control modalities. Further, the suction ring 110 may be an elastomer suction ring that seals to the user so as to assist in suction therapy through the vacuum apertures 112. While a circular suction ring may be shown, other shapes may be used to create a seal, such as an oval. After the suction ring 110 is sealed to a user, the vacuum apertures 112 produce nerve stimuli that distracts the pain signaling stimuli. The vacuum apertures 112 may be evenly spaced in a circular formation within the suction ring 110, as shown, or in any other formation, such as a linear formation, patterned, scattered, etc. It will be appreciated that the vacuum apertures 112 may vary in diameter as well. It will further be appreciated that the intensity of the suction from the vacuum apertures 112 may vary. In an alternate embodiment, the pain-relieving apparatus comprises a single vacuum aperture to provide suction therapy. The suction may be a continuous suction or vary between off and on in various frequencies to change the relief from pain.

As the suction ring 110 can provide a seal for suction therapy, a plate 116 (best shown in FIGS. 1 and 3-4) can provide pain relief through heating or cooling. The plate 116, for example, can be located within the suction ring 110 so that a user can experience suction therapy through the vacuum apertures 112 and heating or cooling simultaneously, which may allow a user's pain to be distracted by multiple pain-relieving modalities. In addition, the vibration stimulators 114 on the stimulating surface 104 may be made from many materials, such as rubber, plastic, or metal. Further, In some embodiments, the vibration stimulators 114 may comprise at least one plate that vibrates and provides heat and cold. While a plurality of vibration stimulators 114 are shown, it will be appreciated it can be as few as one vibration stimulator.

Further, a sound speaker 119 and medicinal holders 120 assist a user by using a different pain relief modality. As a user may experience heat, vibration, and suction, the user can also experience nerve stimulation through sounds and medicine placed on medicinal holders 120. The sound speaker 119 produces sound to stimulate auditory processing and reduce the effect of pain signals to the brain. Various sounds, such as ringing, beeping, or therapeutic music, may be used at a variety of frequencies. Alternatively, the sound may be transmitted from a phone 124 used to control the device via a phone speaker 117 (shown in FIG. 6). While the sound speaker 119 may be used for auditory stimulation, it will be appreciated that sound may also be used for shockwave therapy or ultrasound therapy for controlling pain. The medicinal holders 120 can accept removably attachable medicinal patches 121, such as lidocaine, menthol, or related analgesic patches, to further stimulate the desired nerve. It will be appreciated that other types of local anesthetic may be used in place of lidocaine, such as anesthetic from the ester group (e.g., procaine or benzocaine). All of the pain control modalities can be turned on and off independent of the others as well as adjusted for intensity for unique combinations that provide customizable relief for a user. For example, the user may increase temperature on the plate 116 and have the vibration stimulators 114 at a low frequency to address the user's unique pain.

Referring to FIG. 5, the user inputs 106 may be push buttons; however, it will be appreciated that the user inputs 106 may be knobs, dials, a touch screen, or any other inputting device known in the art. The user actuates the user inputs 106 to control which pain control modality is activated and its intensity, such as vibration at low level. For example, to vary intensity, buttons may be pressed in succession or dials turned, etc. The pain-relieving apparatus 100 operates from a battery which is charged through a battery charging port 108 (shown in FIG. 2), such as a USB port, micro USB port, or AC port. Other charging ports or a charging device known in the art may be used, such as a wireless charging dock. With the use of batteries that can be rechargeable, the user is able to easily carry and operate the pain-relieving apparatus 100 in any location.

A pain-relieving apparatus 100 further comprises the TENS output connector 109. The TENS output connector 109 may be located on the housing 102. The TENS output connector 109 sends small electrical impulses into a painful area of a user via TENS cables 123. The TENS output connector 109, with the TENS cables 123, helps the body produce natural pain relief, often in the form of endorphins. A pain-relieving apparatus 100 further comprises attachment sites 122A, 122B. The attachment sites 122A, 122B allow the pain-relieving apparatus 100 to be coupled to a user by using woven straps, elastic bands, hook and loop straps, or other attachment means.

In some embodiments, as shown in FIGS. 6-7, a pain-relieving apparatus 100 comprises a wireless transceiver that allows it to connect wirelessly to a smartphone or tablet. For example, WiFi® or Bluetooth® connections may be used. The user may then control (i.e., turn modalities on/off and vary intensity) the pain-relieving apparatus 100 via application software on the phone 124 or tablet. In some embodiments, the phone application may also track the different types of pain modalities used as well as their intensity so that a user may have a record of the different approaches and know which approach was successful in either eliminating or decreasing the pain.

In some embodiments, a method of using the pain-relieving apparatus 100 comprises a user placing the pain-relieving apparatus 100 on a painful area of the body and either holding the pain-relieving apparatus in place or securing it via attachment sites 122A, 122B. Through user inputs 106 or via the smartphone 124, the user selects which type of pain control modality to use. The user adjusts whether the pain control modalities are on or off and the intensity of each modality through the user inputs 106 or the software application on the phone or tablet. The user finds the pain control modalities that treat his/her pain best. For example, the user may select a plate 116 and vacuum apertures 112 to provide heat/cold and suction, respectively. The user then determines if the pain control modalities distract the pain stimulus and provide relief. If the modalities do not provide relief, then the user selects other modalities to use, alone or together at various intensities, to determine the best pain relief option.

As shown in FIGS. 8-11, In some embodiments, a pain-relieving apparatus 200 comprises a housing 202, a removably attachable cooling component 204, user inputs 206, and medicinal holders 208. In an alternate embodiment, the removably attachable cooling component 204 may heat as well as cool. The medicinal holders 208, located on the housing 202, may receive any local anesthetics, such as lidocaine patches 210. The lidocaine patches 210, for example, may be releasably adhered to the medicinal holders 208. Further, the housing 202 may vibrate as a whole to provide an additional pain control modality to those mentioned above. It will be appreciated that the pain-relieving apparatus 200, In some embodiments, may further comprise vibration stimulators (e.g., vibrating protrusions). In an alternate embodiment, the pain-relieving apparatus 200 may be a single unit with all the components together in one.

As shown in the pain-relieving apparatus diagram in FIG. 12, power 302 is directed toward control 304 (e.g., microcontroller or other processor). The control 304 can perform I/O (input/output) with therapies 306 (e.g., pain control modalities found on the stimulating surface 104). Further, the control 304 can perform I/O to the user interface 308. The user interface 308 may interact with an audio/video distraction phone app 310 via Bluetooth® or WiFi®. Referring to a power diagram in FIG. 13, a USB connector 312, which may provide a 5V power supply, supplies power to a charger integrated circuit (“IC”) 314 that sends 4.2 V to a lithium-ion battery 316. The lithium-ion battery 316 provides power to various features of the pain-relieving apparatus 100. In particular, the lithium-ion battery 316 supplies a TENS power ICs 318 with 3.7Vnom (battery's nominal voltage). The TENS power ICs 318 may then release 12V. The lithium-ion battery 316 also supplies 3.7Vnom to motor and suction power ICs 320. The motor and suction power ICs 320 may then produce 5V-12V. Lastly, the lithium-ion battery 316 may supply 3.7Vnom to System Power ICs 322. The system power ICs 322 may then produce 3.3V.

Further, as shown in a control diagram in FIG. 14, I/O may be performed via a microcontroller and supporting ICs 324. The microcontroller and supporting ICs 324 can then perform I/O with motor control ICs 326, suction control ICs 328, and TENS control ICs 330. The TENS, motor, and suction control ICs 326-330 can also perform its own I/O.

Therapies, used interchangeably with “pain-control modalities,” can control I/O. For example, as shown in FIG. 15, I/O can be performed for TENS therapy 332, vibration therapy 334, and suction therapy 336, while hot/cold therapy 338 and lidocaine patches 340 do not have I/O. In an alternative embodiment, hot/cold therapy 338 may have I/O capabilities. In FIG. 16, the user interface is shown. In particular, user input buttons 342 can perform I/O and a Bluetooth module 344 can perform I/O and may also receive and/or transmit communication via Bluetooth®.

Referring to FIGS. 17-19, in some embodiments, a pain-relieving apparatus 400 comprises a housing 402, a sound speaker 404, attachment sites 405A-B for coupling the housing to a user, one or more ports, such as a battery charging port 406 and/or auxiliary device ports 408A-B (which may be TENS output connectors such as to couple TENS leads thereto), a user interface such as a touch screen 409, one or more haptic motors 410A-B, patch connectors 411A-B (e.g., snaps for receiving medicated patches, TENS patches, etc.), and a stimulating surface 412 configured to provide therapeutic vibration when actuated by the one or more haptic motors 410A-B. The attachment sites 405A-B, in some embodiments, may comprise a channel 413 or slot in the housing 402 that is configured to receive a strap 415 or tiedown. The strap 415 may be adjustable in length to enable placement of the pain-relieving apparatus 400 along any part of a user's body such as their arms, legs, core, etc. A fit of the strap 415 may be tightened or loosened to further provide control of the proximity and pressure of the stimulating surface 412 to a user's body, thereby aiding in control of overall stimulation and pain relief.

The stimulating surface 412 may comprise a variety of pain control modalities, such as 1) a thermal plate 414 having heat and cold transducer elements (e.g., Peltier element) and may also comprises a heat sink and/or fan, 2) a suction ring, 3) vacuum apertures, 4) vibration stimulators, and/or 5) medicinal holders, as previously disclosed in other embodiments. The pain-relieving apparatus 400 may vary in size and shape. The patch connectors 411A-B are female snaps or ports which may receive male snaps or ports of various patches, including medicinal patches (e.g., lidocaine), TENS patches (the patch connectors 411A-B are capable of conducting electricity), and/or surface altering patches (e.g., bumps, ridges, spikes, etc.). For example, TENS patches may snap into the patch connectors 411A-B and be proximal to the housing 402. A user may then strap the pain-relieving apparatus 400 to their body, where the TENS patches are in contact with the body. However, auxiliary ports 408A-B may also connect TENS leads (e.g., cables), allowing a user to connect TENS patches for placement on the body in a different location from the housing 402. As depicted in these exemplary embodiments, the housing 402 may be rectangularly shaped; however, the housing 402 may alternatively be other formfactors, such as circular, square, hourglass, etc.

Referring to FIGS. 20-21, the one or more haptic motors 410A-B may comprise a linear resonant actuator, an eccentric rotation mass motor, voice coil actuators, or related actuator. As discussed more later herein, a voice coil-style actuator is preferred, as it allows for a plurality of waveforms (e.g., sine, square, triangle, etc.), whereas others, such as the mass rotation motor, are only capable of one waveform (e.g., sine). As shown in FIG. 21, the one or more haptic motor 410 (e.g., a voice coil actuator), in some embodiments, may comprise a coil frame 415 that houses a voice coil 416, a magnet 418 slidable on a rod 420, a first compression spring 422 on a first end of the magnet 418, and a second compression spring 424 on a second end of the magnet 418. As shown, the coil 416 is fixed and the magnet moves on the rod 420. For example, the current flowing through the coil 416 interacts with the permanent magnetic field of the magnet 418 and generates a force vector perpendicular to the direction of the current. This causes the magnet 418 to slide on the rod 420. For example, the magnet 418 may be forced away from the coil 416 when current flows in a first direction. The first compression spring 422 then resists that movement, causing the magnet 418 to oscillate back-and-forth via the magnetic field and the second compression spring 424, creating a desired waveform. Depending on the current supplied to the coil 416, the waveform may by varied from sine, to square, to triangle, or any number of waveforms. As a result, a user is able to adjust/change the waveform to their needs.

Electrical power provided by a power source 424 (FIG. 20), such as a rechargeable lithium-ion battery, non-rechargeable battery, or a cord plugged directly into a power outlet, provides current to the voice coil 416 causing the magnet 418 to move linearly along the rod 420. The one or more haptic motors 410A-B resemble an audio speaker voice coil, enabling a user to incrementally change not only the frequency and amplitude of the vibrations, but also the waveform. In addition, each of the one or more haptic motors 410A-B may be controlled individually, as well as oriented perpendicular to each other, thereby providing greater directional control of the amplitude and variability of the vibrations that are generated.

In some embodiments, the one or more haptic motors 410A-B are configured to provide vibrations with waveforms comprising sine waves, square waves, triangle waves, sawtooth waves, related waveforms, and/or combinations thereof. The sine waves may be sinusoidal waveforms with a smooth periodic function. The square waves may have a non-sinusoidal periodic waveform in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum. The sawtooth waves may be another kind of non-sinusoidal waveform having a resemblance to the teeth of a saw, wherein the waveform ramps upward and then sharply drops. Inverse sawtooth waveforms may likewise be generated by the one or more haptic motors 410A-B. The one or more haptic motors 410A-B, in some embodiments, may create vibratory patterns that approximate those of music (effectively playing a song), illustrating the versatility of the one or more haptic motors 410A-B as compared to traditional vibratory motors known in the art of pain control. By utilizing various waveforms, a user is able to better alleviate pain as compared to the prior art, which is limited to a single waveform.

It will be appreciated that there are different types of pain that the body registers and transmits to the brain, varying from chronic pain such as lower back pain, nerve pain, shingles, or peripheral neuropathy, to acute traumatic injury from tissue damage, such as a contusion, strain, sprain, fracture, or migraine headache. The causes of both acute and chronic pain respond to different modalities of pain relief, including heat, cold, TENS, anesthetics like lidocaine, and vibration therapy. Regarding vibration therapy, alteration of the waveform according to a user's preferences and circumstances surrounding their pain can achieve better pain relief than a single waveform modality traditionally offered by vibratory motors known in the art. For example, some users may respond better to a soothing, low-frequency waveform, while other users may respond better to a harsher, high-frequency waveform that stimulates the nerve fibers enough to numb them and override the subsequent signals sent to the brain.

Methods of pain relief can vary, in part, because some nerve fibers sense pain while others sense heat and cold, light touch, or vibration. For example, although afferent nerve fibers, such as nociceptors, that sense pain may be numbed to completely block pain from being perceived, adjacent vibration sensors such as Merkel cells may still be functional, enabling a user to perceive sensations of touch and movement in the numbed area. The body's use of the same overall nerve fibers to conduct and transmit different sensations can sometimes confuse the brain, thereby interfering with pains signals. Accordingly, use of different modalities of pain relief, such as variable waveforms that affect different sensory cells from different angles, may relieve pain more effectively than a single waveform. Varying between different waveforms, amplitudes, and frequencies during a single treatment may also confuse the nerves and brain and lead to greater pain control from the pain-relieving apparatus 400 from a vibratory modality alone, but when combining this with all other modalities of the pain-relieving apparatus 400 can lead to an even greater enhanced pain control experience.

In practice, a painful area of a user may become numb more quickly while maintaining a harmonic vibration with constant frequency and amplitude, but while varying the waveform between the modalities outlined above. The square waveform, for example, is a comparatively harsher waveform (i.e., has a steeper slope up and down) that may numb the painful area of a user faster than a gentler waveform (i.e., has a less steep slope up and down), such as a sine waveform. Multiple waveform modalities provide a user the option of treating the painful area for less time (e.g., 15-20 minutes) with a high amplitude, high frequency, harsh waveform to help with an acute episode of pain, or treating the painful area for a longer duration (e.g., 5-6 hours) with a comparatively low amplitude, low frequency, smooth waveform for chronic pain. While exemplary time durations and waveforms are discussed herein, a user may either select from preprogrammed waveforms available via a user interface on the touch screen 409 of the pain-relieving apparatus 400 or alternatively customize the waveform on the user interface to correspond to individual needs. The waveforms may be altered or sequenced in an order depending on the location of the painful area, the type of pain experienced, and the preferences of the user. Further, the plurality of motors 410A-B may be arranged in different directions and may be configured to operate simultaneously either at the same waveform or different waveforms from one another. This allows for further customization to a user's pain management needs, which overcomes limitations in the prior art.

Accordingly, the pain-relieving apparatus 100, 200, 400 comprises multiple stimuli to decrease and eliminate pain using, for example, vibration, cooling, heating, suction, TENS (transcutaneous electrical nerve stimulation), lidocaine, and sound to overload the nerve pathways in a unique combinatorial way to decrease and/or eliminate the pain signals traveling to the brain. This allows a user to select specific modalities of pain control so that a person can use one, some, or all of the above modalities to control pain in a non-narcotic or addictive manner. Because all of the modalities are combined into a single apparatus, it is convenient, less expensive, and more effective for a user. As a result, dependence on medication may decrease.

The pain-relieving apparatus 100, 200, 400 could also be used not only for acute and chronic pain control, but to help decrease or prevent pain while undergoing procedures such as peripheral intravenous catheter insertions, intramuscular and subcutaneous injections, wound management, and/or related painful procedures in order to make the patient experience less painful, in both adults and children, and more easy to perform for the healthcare practitioner. A healthcare practitioner or other person may manipulate the pain-relieving apparatus 100, 200, 400 to align the suction ring 110, vacuum apertures 112, vibration stimulators 114, plate 116, heat and cold transducer elements, TENS cables 123, etc. with a corresponding area of a user's body prior to or after the procedure is performed to thereby numb the area and/or reduce painful sensations.
