FIGS. 1-12 show embodiments of a reciprocating treatment device 100. FIGS. 1-4 show the device in schematic form and FIGS. 7-12 show the device 100 in more detail.

FIG. 1 depicts a cutaway side view of one embodiment of a reciprocating treatment device 100. Reference is also made to FIGS. 7-8. The reciprocating treatment device 100 includes a housing 101, a power input 102, a switch 104, a motor 106, and an actuated output 108. The reciprocating treatment device 100, in some embodiments, generates motion at the actuated output 108 for treating a patient.

The housing 101, in one embodiment, is a structure allowing for connection of one or more other components of the reciprocating treatment device 100. The housing 101 may completely or substantially enclose one or more other components. For example, the housing 101 may be a formed structure with attachment points for other components that substantially encloses one or more of those components when assembled. In another embodiment, the housing 101 may allow other components to be exposed. For example, the housing 101 may be an open frame. In some embodiments, the housing 101 encloses one or more components of the reciprocating treatment device 101 and leaves one or more other components of the reciprocating treatment device 101 exposed.

As shown in FIGS. 1, 6 and 7, the housing 101 includes a handle 120. The handle 120 defines a handle axis 122 that runs substantially along the longest dimension of the handle 120. In some embodiments, the handle 120 is straight or substantially straight along its longest dimension, and the handle axis 122 runs through the center or substantially through the center of the handle 120. In another embodiment, the handle 120 is curved along its longest dimension, and the handle axis 122 is tangent to the curvature of the handle 120 at the midpoint of the handle 120. In some embodiment, the handle 120 has a top surface 120a that is shaped that it can be ergonomically gripped by a persons palm. This provides comfort for a user when operating the device. See, for example, U.S. Pat. No. 6,105,891, the entirety of which is incorporated herein by reference, which teaches a fishing reel knob that includes a similar shape that conforms to the user's palm. As shown in FIG. 7, the housing 101 includes the handle 120, a rear portion 121, and a lower portion 123 that includes an upwardly angled neck 125 that extends toward the bulge portion 150. The handle 120, rear portion 121, and lower portion 123 (including the neck 125) define a central opening 127

The power input 102, in some embodiments, is configured to receive a power input from a power source 114. The power source 114 may be any type of power source capable of supplying power to the motor 106. In one embodiment, the power input 102 receives an electrical input from the power source 114. For example, the power source 114 may be a battery that provides electrical current. In one embodiment, the battery is a rechargeable battery. In some embodiments, the battery is attachable to the reciprocating treatment device 100 such that the reciprocating treatment device 100 including the power source 114 is portable and cordless. In an alternative embodiment, the reciprocating treatment device 100 uses an external battery pack as a power source 114.

The battery may be any type of battery known in the art. For example, the battery may include a rechargeable lithium-ion (LiIon) based battery. In another example, the battery may include a rechargeable nickel metal hydride (NiMH) battery. In yet another example, the battery may include a rechargeable lithium-polymer (LiPo) battery. In some embodiments, the battery includes a nickel-cadmium (NiCad) battery. In one embodiment, the battery uses a non-rechargeable battery.

In an alternative embodiment, the power input 102 includes a cord to receive power from an electrical grid. For example, the reciprocating treatment device 100 may include a cord with a plug configured to interface with a wall socket to provide power.

In another alternative embodiment, the power input 102 is non-electrical. For example, the power input 102 may receive pressurized air from a pressure vessel or a network of pressurized air. In another embodiment, the power input 102 may include one or more reactive materials to provide energy for operation of the reciprocating treatment device 100.

The switch 104, in some embodiments, controls delivery of power to the motor 106. The switch 104 may be an electrical switch configured to allow passage of electric current when activated. In some embodiments, the switch 104 is a binary on/off switch. In another embodiment, the switch 104 is a variable switch. A variable switch controls the amount of power delivered to the motor 106. A relatively high amount of power delivered to the motor 106 by the variable switch 104 results in an increased speed of the motor 106. Are relatively low amount of power delivered to the motor 106 by the variable switch 104 results in a decreased speed of the motor 106. In one embodiment, the variable switch 104 includes a variable resistor that allows a progressively increased amount of power to flow to the motor 106 in response to a progressively increasing activation of that switch 104.

In some embodiments, the switch 104 may remain in an activated position in response to a user releasing the switch 104. In an alternate embodiment, the switch 104 may return to a deactivated position in response to a user releasing the switch 104. For example, the switch 104 may include a biasing member such as a spring configured to push the switch 104 to the deactivated position in response to the switch 104 being released.

In certain embodiments, the switch 104 includes multiple positions. For example, the switch 104 may include an off position, a first activated position, and a second activated position. The switch 104 may include one or more positions in which without additional user input, the switch 104 remains in that position, and one or more positions in which without additional user input, the switch 104 is biased to exit that position.

For example, the switch 104 may have an “off” position, an “on” position, and a “turbo” position. The “on” and “turbo” positions may activate reciprocation at different rates, such as 2300 cycles per minute in the “on” position and 2800 cycles per minute in the “turbo” position. Upon being set to the “on” position, the switch 104 may remain in the “on” position without requiring the user to maintain contact with the switch 104. Upon being set to the “turbo” position, the switch 104 may be biased to return to the “on” position unless the user maintains a force on the switch 104 that opposes a return to the “on” position.

The motor 106, in one embodiment, converts power from the power source 102 into motion. In some embodiments, the motor 106 is an electric motor. The electric motor may be any type of electric motor known in the art, including, but not limited to, a brushed motor, a brushless motor, a direct current (DC) motor, an alternating current (AC) motor, a mechanical-commutator motor, an electronic commutator motor, or an externally commutated motor.

In some embodiments, the motor 106 operates at a speed that can be varied by different levels of activation of the switch 104. For example, the motor 106 may operate at a maximum rate in response to a maximum activation of the switch 104. The motor 106 may operate at a lower rate in response to a less than maximum activation of the switch 104.

The motor 106 may produce rotary motion. The rotary motion delivered by the motor 106 may be delivered through a shaft 116. The shaft 116 may rotate around a shaft axis 126. In some embodiments, the reciprocating treatment device 100 may include a linkage to convert the rotary motion of the motor 106 into reciprocating motion. An embodiment of a linkage is shown in greater detail in relation to FIGS. 3A, 3B, and 8-10 below.

In an alternative embodiment, the motor 106 may produce reciprocating motion. For example, the motor 106 may include a reciprocating pneumatic cylinder that reciprocates in response to an input of compressed air.

The actuated output 108, in some embodiments, reciprocates in response to an input from the motor 106. For example, the motor 106 may produce rotary motion. A gearbox may be connected to the motor 106 to convert the rotary motion to reciprocating motion. The gearbox may be connected to the actuated output 108. An embodiment of the gearbox is shown in greater detail in relation to FIGS. 4 and 8-10 below.

In some embodiments, the actuated output 108 reciprocates at a rate of approximately 65 Hz. The actuated output 108, in some embodiments, reciprocates at a rate over 50 Hz. The reciprocating treatment device 100, in some embodiments, provides reciprocation at a rate ranging between 50 Hz and 80 Hz. In some embodiments, the actuated output 108 has a maximum articulation rate of between 50 Hz and 80 Hz. In another embodiment, the actuated output 108 has an articulation rate of between 30 Hz and 80 Hz. In certain embodiments, the actuated output 108 has an articulation rate of approximately 37 Hz. In one embodiment, the actuated output 108 has an articulation rate of approximately 60 Hz. In some embodiment, the actuated output 108 articulates or reciprocates at a frequency of between about 15 Hz and about 100 Hz. In another embodiments, the actuated output 108 articulates or reciprocates at a frequency of between about 25 Hz and about 48 Hz. In some embodiments, the actuated output 108 articulates or reciprocates at a frequency of between about 33 Hz and about 42 Hz. Any chosen range within the specified ranges is within the scope of the present disclosure.

The actuated output 108 may move through a predetermined range of reciprocation. For example, the actuated output 108 may be configured to have an amplitude of one half inch. In another embodiment, the actuated output 108 may be configured to have an amplitude of one quarter inch. As will be appreciated by one skilled in the art, the actuated output 108 may be configured to have any amplitude deemed therapeutically beneficial.

In some embodiments, the actuated output 108 may be adjustable through a variable range of reciprocation. For example, the reciprocating treatment device 100 may include an input to adjust the reciprocation amplitude from one quarter of an inch through a range of up to one inch. In some embodiment, the actuated output 108 moves through an amplitude of between about 0.15 inches and about 1.0 inches. In another embodiments, the actuated output 108 articulates or reciprocates at a frequency of between about 0.23 inches and about 0.70 inches. In some embodiments, the actuated output 108 articulates or reciprocates at a frequency of between about 0.35 inches and about 0.65 inches. Any chosen range within the specified ranges is within the scope of the present disclosure.

It will be appreciated that the device operates most effectively within the combined frequency and amplitude ranges. When developing the disclosure, the inventor determined that if the frequency and amplitude are above the ranges set forth above the device can cause pain and below the ranges the device is ineffective and does not provide effective therapeutic relief or massage. Only when the device operates within the disclosed combination of frequency and amplitude ranges does it provide efficient and therapeutically beneficial treatment to the muscles targeted by the device.

In certain embodiments, the reciprocating treatment device 100 includes one or more components to regulate the articulation rate of the actuated output 108 in response to varying levels of power provided at the power input 102. For example, the reciprocating treatment device 100 may include a voltage regulator (not shown) to provide a substantially constant voltage to the motor 106 over a range of input voltages. In another embodiment, the current provided to the motor 106 may be regulated. In some embodiments, operation of the reciprocating treatment device 100 may be restricted in response to an input voltage being below a preset value.

In some embodiments, the actuated output 108 includes a connector 110 for connection of an attachment. In some embodiments, the actuated output 108 includes a securing mechanism 112 for securing an attachment in the connection socket 110. The connector 110 may be any type of structure capable of retaining an attachment, such as a socket with a latch, a threaded connector, or the like.

For example, the securing mechanism 112 may include a biased structure, such as a spring, to bias the securing mechanism 112 toward a locked position. In the locked position, the securing mechanism 112 may restrict removal of an attachment. The biased structure may be articulated by a user to move the securing mechanism 112 toward an unlocked position. In the unlocked position, the securing mechanism 112 may allow removal of an attachment.

In some embodiments, the securing mechanism 112 includes a keyway to interact with a key on an attachment. The keyway may be selectively opened and closed by articulation of the securing mechanism 112. Removal of an attachment may be restricted in response to the keyway being closed.

As shown in FIG. 9, in another embodiment, the connector 110 can be a male connector and can include at least one (or two) outwardly biased ball bearings 110a that mate with the treatment structure 204.

In certain embodiments, the actuated output 108 reciprocates along a linear or substantially linear path. The path traveled by the actuated output 108 defines a reciprocation axis 124. In certain embodiments, the reciprocation axis 124 runs through the geometric center of one or more components of the actuated output 108.

The actuated output 108, in some embodiments, includes a safety extension 128 between a portion of the housing 101 and a protruding portion, such as the connection mechanism 112. The safety extension 128 provides a region of the actuated output 108 with a substantially constant cross-sectional profile. The safety extension 128 reduces the risk of pinching a body part, such as a finger, as the actuated output 108 actuates. The safety extension 128 may be defined as the region of the actuated output 108 between any non-reciprocating component, such as the housing 101, and any component of the actuated output 108 that has a relatively large or extending cross section, such as the connection mechanism. In one embodiment, the length of the safety extension 128 along the reciprocation axis 124, when measured when the actuated output 108 is fully retracted, is larger than the width of any of an average user's fingers. In some embodiments, the length of the safety extension 128 along the reciprocation axis 124, when measured when the actuated output 108 is fully retracted, is at least 18 millimeters.

In some embodiments, the motor 106 is connected to the housing 101 such that the shaft rotation axis 126 is parallel to a plane defined by the handle axis 122 and the reciprocation axis 124. In one embodiment, the motor 106 is connected to the housing 101 such that the shaft rotation axis 126 is coplanar with a plane defined by the handle axis 122 and the reciprocation axis 124.

FIG. 2 depicts a side view of one embodiment of the reciprocating treatment device 100 of FIG. 1. The reciprocating treatment device 100 includes an attachment 202, a treatment structure 204, and a rest surface 206. The reciprocating treatment device 100, in one embodiment, generates reciprocating motion at the treatment structure 204 for treating a patient.

The attachment 202 may be an interchangeable, user selectable component that is connectable to the actuated output 108. The attachment 202 may include a treatment structure 204 designed to interact with a patient.

The rest surface 206 is a surface disposed on the housing 101. The rest surface 206 is configured such that when the reciprocating treatment device 100 has the rest surface 206 placed on a flat, horizontal surface, the reciprocating treatment device 100 is capable of resting in that position without application of an external force. In other words, when resting as described above, a line drawn downward from a center of gravity of the reciprocating treatment device 100 passes through the rest surface 206. As used in this paragraph, “downward” refers to a direction in which gravity applies a force to objects having mass.

FIGS. 3A, 3B, and 8-11E depict views of embodiments of the actuation components 300 for the reciprocating treatment device 100. The actuation components 300 generally include the motor 106, a compliant shaft damper 302, a shaft 116 with a shaft gear 117 thereon, a gear member 304, an eccentric interface 306, a reciprocator interface 308, a reciprocator shaft 310, and an actuated output 108. The motor 106, the shaft 116, and the actuated output 108 are similar to like-numbered components described above in relation to FIG. 1. The actuation components 300 create motion that is delivered at the actuated output 108.

In one embodiment, rotary motion is delivered from the motor 106 via the shaft 116 and gear 107. In certain embodiments, the motor 106 is connected to other components of the actuation components 300 by a compliant shaft damper 302. The compliant shaft damper 302 comprises a compliant material configured to absorb vibration generated by the actuation components 300. The compliant shaft damper 302 may transmit rotary motion generated by the motor 106 while deforming under vibration loads, thus absorbing or partially absorbing and reducing vibration in the reciprocating treatment device 100.

The compliant shaft damper 302 may include any material capable of absorbing vibration. In some embodiments, the compliant shaft damper 302 includes a polymer. For example, the compliant shaft damper 302 may include a flexible polymer. In one example, the compliant shaft damper 302 includes polyurethane foam, thermoplastic elastomer (“TPE”), including but not limited to Styrenic block copolymers (TPE-s), Polyolefin blends (TPE-o), Elastomeric alloys (TPE-v or TPV), Thermoplastic polyurethanes (TPU), Thermoplastic copolyester, or Thermoplastic polyamide. In another example, the compliant shaft damper 302 may include polyvinyl chloride (PVC), low durometer PVC, or a urethane.

The gear member 304, in one embodiment, receives rotary motion generated by the motor 106. In some embodiments, the gear member 304 rotates in response to rotation of the motor 106. In one embodiment, the gear member 304 rotates around a rotation axis 316 that is perpendicular to a shaft rotation axis 126. For example, the gear member 304 may be part of a bevel gear, a spiral bevel gear, or a hypoid gear. Such gears may have the effect of rotating an axis of rotation by 90 degrees.

In some embodiments, the gear member 304 includes an eccentric interface 306. The eccentric interface 306 is disposed on a surface of the gear member 304 such that it or its center is at a location not on the gear rotation axis 316. In other words, if the gear member 304 is round, the eccentric interface 306 is not disposed at the center of the gear member 304.

In response to rotation of the gear member 304 and subsequent motion of the eccentric interface 306, the reciprocator interface 308 restricts linear motion of the eccentric interface 306 relative to the reciprocator interface 308 to a direction perpendicular to both the reciprocation axis 124 and the gear rotation axis 316. In other words, the eccentric interface 306 is free to slide side-to-side within the reciprocator interface 308 as the gear member 304 rotates. Note that the in addition to sliding relative to the reciprocator interface 308, the eccentric interface 306 may rotate.

As shown in FIG. 9, in some embodiment, the eccentric interface 306 includes a pin 22 and sleeve 24. The pin 22 is received in an off-center opening 26 defined in or through the gear member 304. The sleeve 24 is received in an elongated opening 34 that is defined in an end or head 36 of the reciprocator shaft 310.

The eccentric interface 306, in one embodiment, interfaces with a reciprocator interface or containment member 308. The containment member 308 contains the head 36 of the reciprocator shaft 310 and defines a reciprocation space 38 in which the head 36 of the reciprocator shaft 310 and the eccentric interface components 306 can reciprocate. The containment member 308 includes legs 40 that each include an interior surface that defines a step 42 therein. The larger dimension between the legs defines a space for the head 36 to reciprocate and the smaller dimension between the legs defines a space for the sleeve to reciprocate. In some embodiment, the reciprocator shaft 310 is L-shaped or includes an arm portion so that it connects to the actuated output or shaft 108 along the reciprocation axis.

In some embodiments, the effect of the interaction between the eccentric interface 306 and the reciprocator interface 308 is to convert rotary motion at the gear member 304 to reciprocating, linear motion at the reciprocator shaft 310. The reciprocator shaft 310 transmits reciprocating, linear motion to the actuated output 108.

As shown in FIGS. 3B and 9, in one embodiment, the gear member 304 includes a counterweight 312. The counterweight 312 is configured to oppose inertial forces generated by the reciprocating motion of the actuated output 108. The counterweight 312 may be positioned on the gear member 304 such that its center of mass 314 is not located along the gear rotation axis 316. In certain embodiments, a first direction from the gear rotation axis 316 to the center of mass 314 of the counterweight 312 may be the opposite direction from a second direction from the gear rotation axis 316 to the center of the eccentric interface 306. The counterweight 312 may be located on one side of the gear member 304 and the gear teeth are located on the opposite side. In another embodiment, the gear and counterweight can be separate parts.

In some embodiments, as the reciprocating treatment device 100 operates, the counterweight 312 applies at least a component of force in the opposite direction to a reaction force applied to the eccentric interface 306 by the reciprocator interface 308. In other words, the counterweight 312 may serve to counteract an inertial force generated by reciprocating components and reduce vibration caused by reciprocal motion of the actuated output 108.

In some embodiments, the counterweight 312 may be sized to match reciprocating components of the reciprocating treatment device 100. For example, the counterweight 312 may have a mass similar to reciprocating components, including, for example, the reciprocator shaft 310, the actuated output 108, and an attachment 202. In another embodiment, the counterweight has a mass between 45 grams and 55 grams.

FIG. 11A shows the reciprocator shaft 310 in the extended position and FIG. 11C shows the reciprocator shaft 310 in the retracted position. FIGS. 11B and 11D show the reciprocator shaft in between the retracted and extended positions. Note how the pin 22 and sleeve 24 (eccentric interface) move within elongated opening 34 and the containment member 308 keeps the head 36 of the reciprocator shaft 310 moving linearly. FIG. 11E shows the reciprocator shaft 310 in the extended position, but after the rotation assembly 47 has been rotated, as discussed below.

As shown in FIGS. 8-10, the actuation components 300 include a guide member 30 that includes a central opening through which the reciprocator shaft 310 extends. The guide member 30 is housed in the rotation housing 44 and remains stationary as the reciprocator shaft moves therein. In some embodiment, the actuation components 300 also include a pin or axle 16 on which the gear member 304 rotates a bearing 14 and a dampening ring 28 for damping the connection between the housing and the metal components.

FIGS. 4 and 8-11E depict embodiments of actuation components 300 of the reciprocating treatment device 100. The actuation components include the motor 106, the gear member 304, the reciprocator shaft 310, one or more compliant dampening blocks 402 and, a gearbox 404. The actuation components 300 provide reciprocating motion through the reciprocator shaft 310 and manage vibration transmitted to the housing 101.

The one or more compliant dampening blocks 402 manage vibration conducted from the actuation components 300 to the housing 101. The one or more compliant dampening blocks 402 may be disposed between the actuation components 300 and the housing 101.

The one or more compliant dampening blocks 402 may include any material capable of absorbing vibration. In some embodiments, the one or more compliant dampening blocks 402 include a polymer. For example, the one or more compliant dampening blocks 402 may include a flexible polymer. In one example, the one or more compliant dampening blocks 402 include polyurethane foam, thermoplastic elastomer (“TPE”), including but not limited to Styrenic block copolymers (TPE-s), Polyolefin blends (TPE-o), Elastomeric alloys (TPE-v or TPV), Thermoplastic polyurethanes (TPU), Thermoplastic copolyester, or Thermoplastic polyamide. In another example, the one or more compliant dampening blocks 402 may include polyvinyl chloride (PVC), low durometer PVC, or a urethane.

The gearbox 404, in one embodiment, includes the gear member 304 and the reciprocator 310. The gearbox 404 may provide mounting points for the gear member 304 and the reciprocator 310. The gearbox 404 may restrict the motion of the gear member 304 and the reciprocator to certain directions or rotational axes. The gearbox 404 may be mounted to the housing 101. In some embodiments, the gearbox 404 is separated from the housing 101 by the one or more compliant dampening blocks 402.

As is shown in FIGS. 11C and 12, in some embodiments, the actuated output 108 and associated components are rotatable relative to the housing 101. The actuated output 108 may rotate relative to the housing 101 around an output rotation axis. In certain embodiments, the output rotation axis is parallel to the gear rotation axis 316. In one embodiment, the output rotation axis is concomitant with the gear rotation axis 316. For example, the actuated output 108, the reciprocator 310, and the reciprocator interface 308 may be selectively rotatable around the gear rotation axis 316.

In one embodiment, rotation of the actuated output 108 may be selectively locked and unlocked by a user. For example, the user may unlock rotation of the actuated output 108, rotate the actuated output 108 to a desired position relative to the housing 101, lock rotation of the actuated output 108, and operate the reciprocating treatment device 100.

As shown in FIG. 12 in some embodiment, the rotation assembly 47 includes the rotation housing 44 (which includes first and second rotation housing halves 44a and 44b), an articulation lock or a button 46 having teeth 48 thereon and a spring 18 that contacts seating surface 43. The gear member 304, reciprocator shaft 310, axle 16, a portion of the gear box 404, and bearing 14 are all housed in the rotation housing 44. The assembly also includes a gear box cover 56 and dampening ring 52. Button 46 is outwardly biased by spring 18 to a position where teeth 48 are engaged with teeth 50 defined in housing 101. The button 46 is movable between a first position where teeth 48 are engaged with teeth 50 and a second position where teeth 48 are engaged with teeth 54 in the second rotation housing half 44b. When the button 46 is in the first position, the rotation assembly 47 cannot rotate. When the button is pushed to the second position, the teeth 48 disengage from teeth 50 and engage the teeth 54 in the rotation housing 44, thereby allowing the entire rotation assembly 47 to rotate. The rotation housing 44 includes a main body portion 62 disposed in the housing and an arm portion 64 extending through the rotation space 60 and outside the housing. The arm portion 64 rotates within the rotation space 60 defined in the housing 101. It will be appreciated, that when rotation occurs, gear member 304 and gear box 404 do not rotate (compare FIGS. 11A-11D to FIG. 11E), but the containment member 308 together with the actuated output 108 do rotate. As shown in FIGS. 8, 9 and 12, the housing 101 includes a bulge portion 150 having a first bulge portion surface 150a positioned on a first side of a plane that bifurcates the housing 101 (referred to herein as the “housing plane”) and a second bulge portion surface 150b positioned on a second side of the housing plane. The handle 120 includes a first handle side surface 120b positioned on the first side of the housing plane and a second handle side surface 120c positioned on the second side of the housing plane. The first bulge portion surface 150a is located further from the housing plane than the first handle side surface 120b and the second bulge portion surface 150b is located further from the housing plane than the second handle side surface 120c.

FIG. 5 depicts a flowchart diagram showing one embodiment of a method of manufacture of the reciprocating treatment device of FIG. 1.

FIGS. 5 and 6 are flowchart diagrams depicting embodiments of a method 500 for manufacturing the reciprocating treatment device 100 of FIG. 1 and a method 600 of use of the reciprocating treatment device 100 of FIG. 1. The methods 500, 600 are, in certain embodiments, methods of use of the system and apparatus described herein, and will be discussed with reference to those figures. Nevertheless, the methods 500, 600 may also be conducted independently thereof and are not intended to be limited specifically to the specific embodiments discussed above with respect to those figures.

As shown in FIG. 5, a method of manufacture 500 for a reciprocating treatment device 100 is shown. In one embodiment of the method of manufacture 500, a housing 101 is provided 502. The housing 101 may include a handle 120 and the handle 120 may define a handle axis 122. A motor 106 is connected 504 to the housing 101. The motor 106 may provide rotary motion.

In some embodiments, an actuated output 108 is operably connected 506 to the motor 106. The actuated output 108 may reciprocate in response to activation of the motor 106. Reciprocation of the actuated output 108 may be along a reciprocation axis 124.

In some embodiments, the motor 106 includes a shaft 116. The shaft 116 may rotate around a shaft rotation axis 126. The shaft rotation axis 126 may be parallel to a plane in which the handle axis 122 and the reciprocation axis 124 are located.

As shown in FIG. 6, a method of use 600 for a reciprocating treatment device 100 is shown. In one embodiment of the method of use 600, a force is applied 602 to a body part by an actuated output 108 of the reciprocal treatment device 100. The reciprocal treatment device 100 may include a housing 101. The housing 101 may include a handle 120 disposed on the housing 101. The handle 120 may define a handle axis 122.

The reciprocal treatment device 100 may also include a motor 106 connected to the housing 101. An actuated output 108 may be operably connected to the motor 106. The actuated output 108 may be configured to reciprocate in response to activation of the motor 106. Reciprocation of the actuated output 108 may be along a reciprocation axis 124.

The motor 106 may include a shaft 116 having a shaft rotation axis 126. The shaft rotation axis 126 may be parallel to a plane in which the handle axis 122 and the reciprocation axis 124 are located.

FIGS. 14-27 show further embodiments of the present disclosure. Many of the components of the reciprocal treatment devices or percussive massage devices of FIGS. 14-27 are the same or similar as those discussed above with respect to reciprocal treatment device 100. Accordingly, the description hereinafter focuses on components that are different.

FIGS. 14-23 show an embodiment of a percussive massage device 212 that includes a rechargeable battery (and replaceable or removable battery) 114. Device 212 is referred to commercially as the G3PRO. As shown in FIGS. 14-15, in some embodiment, the percussive massage device 212 includes three handle portions (referred to herein as first handle portion 143, second handle portion 145 and third handle portion 147) that cooperate to define a central or handle opening 149. All of the handle portions are long enough that they are configured such that a person can grasp that particular handle portion to utilize the device. The ability to grasp the different handle portions allows a person (when using the device on their own body) to use the device on different body parts and from different angles, thus providing the ability to reach body parts, such as the back, that might not be possible without the three handle portions.

As shown in FIG. 14, the first handle portion 143 defines a first handle portion axis A1, the second handle portion 145 defines a second handle portion axis A2 and the third handle portion 147 defines a third handle portion axis A3 that cooperate to form a triangle. In some embodiment, the battery 114 is housed in the second handle portion 145 and the motor 106 is housed in the third handle portion 147.

FIGS. 16-18 show a user's hand grasping the various handle portions. The length of each of the first, second and third handle portions is long enough so that a person with a large hand can comfortably grasp each handle portion with at least three to four fingers extending through the handle opening, as shown in FIGS. 16-18. In some embodiment, the first handle portion 143 has an interior edge 143a, the second handle portion 145 has an interior edge 145a and the third handle portion 147 has an interior edge 147a, which all cooperate to at least partially define the handle opening 149. As shown in FIG. 14, in some embodiment, the first handle portion 143 includes a finger protrusion 151 that includes a finger surface 151a that extends between the interior edge 143a of the first handle portion and the interior edge 147a of the third handle portion 147 and at least partially defines the handle opening 149. As shown in FIG. 16, in use, a user can place their index finger against the finger surface 151a. The finger protrusion and surface provide a feedback point or support surface such that when a user places their index finger against the surface it helps the user with control and comfort of using the device. In some embodiment, at least a portion of the finger surface 151a is straight, as shown in FIG. 14 (as opposed to the other “corners” of the handle opening 149 being rounded.

FIG. 14A shows the exemplary dimensions of the interior surfaces of the handle opening 149. It will be appreciated that the interior surfaces comprise a series of flat and curved surfaces. H1 is the dimension of the interior edge 143a of the first handle portion 143 (the first handle portion length). H2 is the dimension of the interior edge 145a of the second handle portion 145f (the second handle portion length). H3 is the dimension of the interior edge 147a of the third handle portion 147 (the third handle portion length). H4 is the dimension of the finger surface 151a (the finger protrusion length). R1 is the dimension of the radius between interior edges 143a and 145a and R2 is the dimension of the radius between interior edges 145a and 147a. In some embodiment, H1 is about 94 mm, H2 is about 66 mm, H3 is about 96 mm, H4 is about 12 mm, R1 is about 6.5 mm and R2 is about 6.5 mm, which provides an arc length of about 10.2 mm. In the context herein, “about” is within 5 mm. In some embodiment, the length of the interior edge of the handle opening is about 289 mm. The length of the interior edge of the handle opening can be between about 260 mm and about 320 mm, with any combination of H1, H2, H3, H4, R1 and R2. It will be appreciated that these dimensions are optimized so that a 95th percentile male can grip any of the three handle portions with at least three or four fingers extending through the handle opening to utilize the device. It will be appreciated that any or all of surfaces R1 and R2 can be considered a part of any of the three adjacent handle portions. As shown in FIGS. 14 and 14A, with the finger surface 151a being straight, the first handle portion interior surface, second handle portion interior surface, third handle portion interior surface and finger surface cooperate to define a quadrilateral with radii or rounded edges between each of the straight surfaces.

Device 212 also includes multiple speed settings (e.g., 1500 and 2400 RPM, but can be any speed or frequency taught herein). Furthermore, those of ordinary skill in the art will appreciate that although the RPM is listed as a specific number that, due to manufacturing tolerances, the RPM may oscillate during use. For example, at the 2400 RPM setting the RPM may actually oscillate between 2260 and 2640.

FIGS. 19-23 show some of the interior and exterior components that are included in the treatment devices 212 (208 and 210) shown in FIGS. 14-18 and 24-27. As shown in FIG. 19, the percussive massage device 212 includes a housing 101 that is comprised of first and second housing halves 103. Outer covers 213 and top cover 215 are received on and connected to the first and second housing halves 103, via tabs 105 or other mechanism or attachment method (e.g., threaded fasteners, clips, adhesive, sonic welding, etc.). The percussive massage device 212 also includes a tambour door 217, battery 114, inner suspension rings 219 and rotation housing 44 (with first and second rotation housing halves 44a and 44b) that houses the gearbox 404.

As shown in FIG. 20, the device includes a pinion coupling assembly 216 (similar to the compliant shaft damper 302 described above) that is disposed between the motor and the pinion shaft or shaft gear 117 (located on the shaft or pinion shaft 116). The pinion coupling assembly 216 is used to couple the motor to the gearbox so that the torque is fully transmitted, such that there is no radial movement and the vibrations and noise are minimized. The pinion coupling assembly 216 may include three separate components, a lower connector 218, a cross coupling 220 and an upper connector 222. In some embodiment, the lower connector 218 includes a main body portion 218a that defines a central opening 218b that receives the motor shaft 248 and first and second lower connector arms 218c extending outwardly from the main body portion 218a. The upper connector 222 includes a main body portion 222a that defines a central opening 222b that receives the pinion shaft 117 and first and second upper connector arms 222c extending outwardly from the main body portion 222a. The cross coupling 220 may include radially extending ribs 220a that define channels 220b therebetween. The first and second lower connector arms 218c and the first and second upper connector arms 222c are sized and shaped to be received in the channels 220b to operatively engage the radially extending ribs. In use, the motor shaft 248 rotates the pinion coupling assembly, which rotates the pinion shaft 117. These components work together to reduce noise and vibration. In some embodiment, the lower and upper connectors are made of plastic and the cross coupling is made of an elastomer. In some embodiment, the cross coupling 220 is made of rubber that includes a hardness where vibrations generated by the motor are isolated while keeping the strength and transmitting the torque efficiently (without significant energy dissipation). However, the materials are not a limitation on the present disclosure.

In some embodiment, the pinion shaft 116 is received in and extends through bearings 224 and 225. Bearing 224 may include ball bearings (and provides radial support) and bearing 225 includes needle bearings (and provides radial support, but can withstand higher temperatures). The pinion coupling assembly 216 is housed in motor mount 250, which is connected to the motor 106 and through which the motor shaft 248 extends. The motor mount 250 is connected to the gear box mount 252, as shown in FIG. 22.

As shown in FIGS. 20-22, the gearbox 404, in one embodiment, includes the gear member 304 and the reciprocator or push rod 230/310. The gear member 304 includes a shaft 246 extending therefrom to which the reciprocator 310 is connected. The gearbox 404 may provide mounting points for the gear member 304 and the reciprocator 310. The gearbox 404 may restrict the motion of the gear member 304 and the reciprocator to certain directions or rotational axes. The gearbox 404 may be mounted to the housing 101. In some embodiments, the gearbox 404 is separated from the housing 101 by the one or more compliant dampening blocks 402.

As shown in FIGS. 19 and 21, in some embodiment, to prevent the gearbox from transmitting vibrations to the housing a rubber cover can be provided. Further inner suspension rings 219 isolate vibration of the gearbox from handle and the treatment structures. The rings 219 are made of an elastomer and act as a cushion to dampen vibrations between the rotation housing and the housing 101. In some embodiment, the inner suspension rings 219 surround the outer radial surface of the main body portion 62 (see seat surface 523 in FIG. 21).

In one embodiment, rotation of the actuated output or shaft 108 may be selectively locked and unlocked by a user. For example, the user may unlock rotation of the shaft 108, rotate the actuated output 108 to a desired position relative to the housing 101, lock rotation of the actuated output 108, and operate the reciprocating treatment device 100. FIG. 21 shows the components that allow rotation of the rotation housing 44 together with the push rod assembly 108 and related components. Button 515 includes radially extending teeth 515a and is biased outwardly by spring 519, which surrounds and is seated on spacer 518 (which may be made of, e.g., foam). Spring 519 is seated against dampening members 520 and 517, which may be made of rubber to dampen any vibrations of the spring 519. The assembly also includes a gear box cover 525 and dampening ring 521. Button 515 is outwardly biased by spring 519 to a position where teeth 515a are engaged with teeth 516a, which are defined hoop 516, which is connected to housing 101. The hoop 516 may include inner and outer plastic rings 516b and 516c that sandwich a rubber ring 516d therebetween to help dampen vibrations and reduce noise. The button 515 is movable between a first position where teeth 515a are engaged with teeth 516a and a second position where teeth 515 are not engaged with teeth 516a. When the button 515 is in the first position, the rotation assembly 47 cannot rotate. When the button is pushed to the second position, the teeth 515a disengage from teeth 516a, thereby allowing the entire rotation assembly 47 to rotate. The rotation housing 44 includes a main body portion 62 disposed in the housing and an arm portion 64 extending through the rotation space 60 and outside the housing. The arm portion 64 rotates within the rotation space 60 defined in the housing 101. As shown in FIG. 15, in some embodiment, the device 212 includes a tambour door 217 that unfolds within the rotation space 60 as the rotation assembly is moved from the position shown in FIG. 14 to the position shown in FIG. 15. The tambour door 217 covers slot 214. As shown in FIG. 15, an arm cover 524 covers the arm portion 64 of the rotation housing 44.

As shown in FIG. 22, the gearbox housing 404 includes a clearance slot 214 defined therein for the push rod assembly 108. The slot 214 is provided so the push rod assembly 108 can move freely and allow the rotation housing 44 to articulate. The clearance slot 214 has first and second ends 214a and 214b. As shown in FIG. 22, the push rod assembly 108 extends through the clearance slot 214. it will be appreciated that when the rotation housing 44 is rotated from a first position to a second position the push rod assembly 108 moves within the clearance slot 214 from the first end to the second end thereof.

As shown in FIGS. 21-23, in some embodiment, the pushrod assembly or output shaft 108 includes two halves or rods with an adapter member 226 therebetween to also help reduce noise and vibration. The adapter member 226 isolates the vibrations generated in the gearbox and prevents them from being transmitted down the shaft to the treatment structure. The adapter member 226 can include anti-rotation tabs to protect the push rod from user applied torque during use. The first rod portion 230 of the output shaft 108 (push rod or reciprocator 310) includes an opening 232 on an end thereof that receives a pivot pin 234. The connection between the first rod portion 230 and the adapter member 226 includes a bushing 227 with the pin 234 and elastomeric material to dampen vibrations. The end of first rod portion 230 that includes opening 232 is received in a pocket 229 in adapter member 226. The pin 234 extends through openings in the side walls of adapter member 226, through bushing 227 and through opening 232, to secure first rod portion 230 to adapter member 226. Adapter member 226 includes a protrusion 231 extending therefrom that is received in an opening 233 in an end of the second rod portion 236, to connect the adapter member 226 to the second rod portion 236. In another embodiment, the end of the second rod portion 236 can be received in an opening in the adapter member 226. In use, the size of the top opening of pocket 229 allows the first rod portion to move side to side as the opening 232 pivots on pin 234 and first rod portion 231 reciprocates. This translates to linear reciprocation of second rod portion 236. Because the bushing 227 comprises at least some elastomeric material, vibrations are dampened (and noise reduced) as the push rod assembly 108 reciprocates.

Ring 526 is seated on and surrounds the bottom portion of the arm portion 64 (see seat 64a in FIG. 21) to help hold the first and second housing halves 44a and 44b together. Washer or guide member 527 is received in the rotation housing 44 and provides stability and a path for the reciprocating push rod assembly or output shaft 108.

As shown in FIG. 22, in this embodiment, the first rod portion 230 or push rod assembly 108 extends through clearance slot 214. It will be appreciated that the term pushrod assembly includes any of the embodiments described herein and can include a shaft with an adapter member allowing pivoting between two halves or can include a single shaft that does not include any pivoting.

As shown in FIGS. 22-23, in some embodiment, the male connector 110 includes an alignment tab 497 above each ball that mates with a slot in the female opening. These tabs 497 help with proper alignment with the treatment structure. See U.S. Patent App. No. 2019/0017528, the entirety of which is incorporated herein by reference.

FIGS. 24-29 show embodiments of percussive massage devices similar to percussive massage device 212 above, but without a rotation assembly. Device 208, shown in FIGS. 24-27 is referred to commercially as the G3. Device 210, shown in FIGS. 28-29 is referred to commercially as the LIV. As is shown in FIG. 26, in some embodiment, switch 104 includes switch electronics 575 associated therewith. The switch electronics 575 may include a printed circuit board (PCB) and other components to allow the switch 104 to activate the motor 106 and to change the speed of the motor, turn the device on and off, among other tasks. As shown in FIG. 26, in some embodiment, the motor 106 is housed in the third handle portion 147, the battery 114 is housed in the second handle portion 145 and the switch electronics 575 are housed in the first handle portion 143. This configuration also applies to devices 210 and 212. FIG. 27 shows cushion members 577 that surround the gearbox 404 and help dampen and reduce noise and vibration generated by the components in the gearbox. Cushion members 577 are similar to inner suspension rings 219 in device 212. However, cushion members 577 are thicker and do not need to rotate due to the exclusion of the rotation housing in devices 208 and 210. Cushion members 577 include cutouts or channels 579 therein to allow clearance of components such as the push rod assembly and pinion shaft.

FIGS. 30-33 show one type of attachment module 412 that is configured to be attached or secured to the housing 101 of the percussive therapy device 100 (or any of the percussive therapy device embodiments described herein). This provides interchangeability between attachment modules with different active effects. In some embodiment, the attachment module is configured to provide an active effect either to the user of the device or with respect to the device. All of the therapeutic effects, sensors, actuators, gyroscopes, accelerometers or other active features described herein are encompassed within the phrase “active effect.” These can include global biometric sensors, local biometric sensors and/or actuators, such as, heart rate, heart rate variability, SPO2, respiratory rate, muscle temperature, muscle oxygen saturation, blood flow, cold therapy, heat therapy, light therapy (red, infrared, blue, etc.), photobiomodulation therapy, vibration therapy, exfoliating therapy, obtaining biometric data of the user (e.g., temperature, heart rate, blood pressure, oxygen saturation, blood flow sensing), angular position data of the percussive therapy device, linear position data of the percussive therapy device, microcurrent therapy, radio frequency therapy, ultrasound therapy, infrared therapy, far infrared therapy, electric muscle stimulation, etc. Some of the active effects are associated with providing a therapy to the user and others (e.g., angular and linear position sensing) are associated with the device.

As shown in FIGS. 30 and 31, in some embodiment, the attachment module 412 is received in a module recess 414 or module seat that is defined in the bottom or belly of one of the third handle portion 147 of the housing 101. The module recess 414 can be defined anywhere within the housing or on any of the handle portions of the device. In some embodiment, the attachment module 412 is in electrical communication with the electrical source (e.g., rechargeable battery). The housing 101 includes a first electrical connector 416 and the attachment module 412 (e.g., associated with a housing 315 of the attachment module 412) includes a second electrical connector 318. Connection of the first and second electrical connectors provides electrical communication between the electrical source and the attachment module 412. The first electrical connector 416 can be located on the outer surface of the housing 101 or within the module recess 414. In some embodiment, connection of the first and second electrical connectors 416 and 318 also provides data communication between the percussive therapy device (e.g., to the PCB 504) and the attachment module 412.

In embodiments, the attachment module 412 is secured in place with one or more magnets. There is magnetic attraction between the attachment module 412 and the module recess 414 or module seat. In other words, a first magnet or set of magnets can be located in or on the attachment module 412 and a second magnet or set of magnets can be located in, on, within or adjacent to the module recess 414 or module seat.

The attachment module 412 can be secured or attached to or within the module recess 414 via other methods or technologies, such as latches, detents, pawls, friction fit, snap fit, etc. The device 100 can include a button 320 that can be pressed to remove the attachment module 412. The button 320 can be located anywhere on the housing or on the attachment module itself. The button 320 is shown in FIG. 30 next to a button 322 used for removal of the battery 114. In FIG. 30, the attachment module 412 includes a heating element 324 (which can provide heat or cold therapy as the active effect). FIGS. 32A, 32B, and 32C show exemplary attachment modules 412 that include various types of active effects. FIG. 32A shows the heating element 324, FIG. 32B shows a plurality of LEDs 326 for provision of LED light or photobiomodulation therapy, and FIG. 32C shows a temperatures sensor 328.

Attachment module 412 may include any of the features described herein with respect to attachment module 520, such as integration of the data obtained from the attachment module 412 with the protocols discussed herein, inclusion of a PCB and/or controller. Furthermore, the active effect provided by the attachment module 412 can be included in one or more protocols. For example, if the attachment module 412 provides heat therapy, a protocol may include steps where the user is directed to place the heating element against a body part for a predetermined period of time.

In another embodiment, attachment module 412 can be permanently attached to or within the housing 101. In other words, in this embodiment, attachment module 412 is not readily removable (or intended to be removable) by a user of the device (as opposed to a user taking the device apart to remove the attachment module). The attachment module is secured to or within the housing during manufacturing of the device as not intended to be removed by an end user of the commercial product. It is not interchangeable with other attachment modules. For example, FIG. 33 shows an attachment module 412 permanently attached within the housing 101 and configured to provide heat therapy via heating element 324. In this example, the attachment module can only be removed from the housing by someone using tools to take the device apart and remove the heating element and associated portions of the attachment module. This is in contrast to the interchangeable modules that are easily and readily removable from the housing by the user (e.g., via pulling the attachment module away from the housing to break the magnetic attraction or pushing a button to remove the attachment module).

FIGS. 34-36 show another embodiment where the percussive massage device 436 includes a heart rate sensor 437 that is located on the top handle or first handle portion 143 of the device. The heart rate sensor 437 can be located either side of the first handle portion 142 (top or bottom side) to be in contact with, for example, palm of a user's hand or an index finger of the user. Alternatively or additionally, heart rate sensor 437 may be located on any portion of the housing 101. In some embodiments, heart rate sensor 437 may be integrated with the device 436 similar to the attachment module 412 in FIG. 33 or configured to be attachable thereto. That is, the heart rate sensor 437 may be a built-in module or may be an attachment module that can be removable or non-removable. Any type of heart rate sensor is within the scope of the invention. The heart rate sensor 437 is a heart rate sensor that uses infrared to measure and record heart rate and can also measure and record heart rate variability, if desired. In an exemplary use, heart rate is measured using a process called photoplethysmography or PPG. This involves shining a specific wavelength of light, which usually appears green, from a pulse oximeter sensor on the underside or upper side (e.g., top of the first handle portion) of the device where it touches the skin. As the light illuminates the tissue, the pulse oximeter measures changes in light absorption and the device then uses this data to generate a heart rate measurement. The electronics associated with heart rate sensor 437 are included in the housing 101 and can be separate or on the main PCB. A screen 409 displays the heart rate data. A heart rate monitor opening 438 is defined in the housing and the heart rate sensor 437 is mounted therein, as shown in FIG. 34.

FIG. 36 shows another type of heart rate monitor or sensor 439 that can be utilized and includes first and second pulse sensors or contacts 440. A first pulse sensor is positioned so that it contacts the user's palm in use and the second pulse sensor is positioned so that it contacts the user's fingers in use. The first handle portion 143 can also include an indent where the contact is located so the user knows where to place their index finger. Other sensors, actuators or components that provide an active effect that can be included on the handle portions include other global biometric sensors, such as those that can sense or determine heart rate variability, SPO2 (peripheral capillary oxygen saturation) and/or respiratory rate. It will be appreciated that the any of the sensors, actuators or components discussed herein that provide an active effect can be positioned on any of the first, second and/or third handle portions or on all three handle portions.

FIG. 37 shows a device 457 including a thermal sensor 462. Any type of thermal sensor is within the scope of the invention. The thermal sensor 462 is an infrared thermometer module installed in the housing 101 of the device (e.g., on the third handle portion 147) that allows the user to measure the temperature of the user's muscles or other body part. The thermal sensor 462 is preferably in data and/or electrical communication with the PCB. The temperature data can also be communicated to the app. In an infrared thermometer, infrared light is focused on the body part to be measured or to be treated or while being treated and the infrared thermometer module measures energy or radiation coming from the surface. The detector then translates the amount of electricity generated into a temperature reading of the particular muscle, body part, etc. The infrared beam is emitted through an opening in the third handle portion 147 of the housing 101 and the module is mounted within the housing.
