Description

Technical Field

[0001] This invention relates to a dry massage device; and a method for performing a dry massage on a patient using the dry massage device. Background Technology

[0002] Pressurized water jets or a combination of water and air are known to be used to provide wet massage for therapeutic, athletic, or recreational purposes, including spas, hot tubs, and whirlpools. In these applications, the water jet is typically positioned below the waterline, and the user sits largely submerged in the tub. The water jet remains stationary, and the user cannot move while using the device. During use, the impact of the water flow on the user's body, as well as the turbulence created by the water flow in the tub, provides a soothing massage effect.

[0003] The advantage of positioning the water jet below the waterline is that it minimizes splashing onto the user and the area around the bathtub. However, the position of the jet is often fixed or not maneuverable by the user during a massage, thus limiting the ability to provide a targeted massage, as it requires the user to move themselves relative to the jet. This is both inconvenient and difficult for users with limited mobility.

[0004] In medical applications, such as inpatient and outpatient clinics, handheld high-pressure water jets can be used. This has the advantage of allowing the user to manipulate the position of the water jet, facilitating massage of almost any area of ​​the body. Pressure can also be easily controlled by moving the jet closer to or further away from the patient. However, these handheld devices result in significant splashing, and both the user and patient must change out of their usual clothing for the massage. Furthermore, the excessive splashing limits the use of such devices to areas with adequate drainage, making them unsuitable for portable use and significantly limiting their practicality.

[0005] The present invention solves, at least to some extent, these and other problems of the prior art. Summary of the Invention

[0006] Therefore, in a first aspect, the present invention provides a dry massage device comprising a main chamber, wherein the main chamber includes an inlet configured to allow fluid to enter the main chamber and an outlet configured to allow fluid to exit the main chamber. The main chamber is defined by an outer wall including a surface for contacting a patient. The device is configured such that, in use, the direction of fluid entering the main chamber relative to the surface contacting the patient can be changed by the user, while the surface remains substantially stationary relative to the patient.

[0007] For the purposes of this invention, "still" means that the area of ​​the main chamber in contact with the patient does not slip across the patient's surface during normal use. Typically, the patient's surface will be an area of ​​the patient's skin. The ability to change the direction of the fluid as it enters the main chamber allows targeted massage to be delivered to a patient area larger than the fluid inlet size, without requiring repositioning of the main chamber or patient movement.

[0008] This device is a dry massage device, so neither the user nor the patient will come into contact with fluids (such as water or aqueous solutions) during normal operation of the device.

[0009] The device is configured to have an outlet through which fluid exits the main chamber. Therefore, the pressure in the main chamber does not exceed a predetermined threshold. Advantageously, this ensures that the main chamber is not overfilled and / or expanded by fluid, which could potentially damage the equipment. The fluid outlet can passively or actively remove fluid from the chamber. When the fluid outlet actively removes fluid from the main chamber, the fluid can be pumped by a pump system, which can be the same pump system used to pump fluid through the fluid inlet. If the fluid outlet is passive, water can simply be discharged from the outlet into a drainage system or a collection system. Preferably, the fluid outlet is an active outlet in fluid communication with the pump system that recirculates the fluid back to the main chamber.

[0010] Typically, the main chamber volume is between 3 and 6 liters. A larger main chamber volume makes it easier to control the pressure applied to the patient. Devices with a larger main chamber volume (e.g., 6 liters) may require external support.

[0011] Typically, the fluid inlet can be located at the first end of the main chamber, and the patient contact surface can be located at the second end of the main chamber opposite the first end. The fluid inlet can be integrated into the handle of the device. Typically, the fluid entering the main chamber is directed to the surface used for contact with the patient.

[0012] Typically, the fluid outlet can be located at the first end of the main chamber, preferably adjacent to the fluid inlet.

[0013] The main chamber may include a relatively rigid portion having a fluid inlet and / or a fluid outlet, and a relatively flexible portion including a patient contact surface.

[0014] Preferably, during use, the fluid inlet is movable relative to the surface used for contacting the patient, while the surface used for contacting the patient remains stationary in contact with the patient. Typically, the angle formed between the longitudinal axis of the fluid inlet and the surface used for contacting the patient can be changed, while the surface used for contacting the patient remains substantially stationary.

[0015] Preferably, the fluid inlet is movable in a plane substantially parallel to the surface used for contacting the patient, which is in static contact with the patient. Preferably, the fluid inlet is movable in a direction tangential to the plane parallel to the surface used for contacting the patient.

[0016] Moving the fluid inlet toward the patient increases the pressure applied to the treatment surface, while moving it away from the patient decreases the pressure. This is because removing the fluid inlet from the treatment surface can increase the fluid volume between the inlet and the chamber wall. Therefore, advantageously, the intensity of the massage can be varied without changing the fluid pressure at the inlet.

[0017] Moving the fluid inlet parallel to the patient allows for an increase in the area of ​​the patient being treated. This is because the fluid inlet is movable, enabling it to be guided to treatment surface areas that would not be reached if the fluid inlet were in a fixed position.

[0018] In one embodiment, the portion of the main chamber in contact with the patient can be altered, while the surface of the main chamber in contact with the patient remains substantially stationary. This allows the chamber to move above the patient without slipping. This movement mechanism can be considered analogous to the movement of tracks.

[0019] Advantageously, this arrangement can increase the area of ​​the patient that can be treated without having to remove or slide the main chamber. Similarly, the total area of ​​the main chamber surface in contact with the patient preferably increases or decreases as the fluid inlet moves toward or away from the treatment surface.

[0020] Typically, the fluid inlet may include an inlet nozzle, which is movable within the main chamber.

[0021] Typically, the inlet can be configured such that the distance from the fluid inlet nozzle to the surface used for contacting the patient is variable. Preferably, the fluid inlet nozzle can be inserted into the main chamber through the nozzle inlet, allowing fluid to flow into the main chamber through the inlet nozzle.

[0022] Typically, the inlet nozzle can be connected to the main chamber via a set of rollers and / or flexible seals. In some embodiments, the inlet nozzle can be detachably connected to the main chamber. Alternatively, the inlet nozzle can be permanently connected to the main chamber.

[0023] In embodiments with a removable inlet nozzle, the chamber may include a seal that forms a fluid seal with the fluid inlet nozzle. Therefore, the seal ensures that fluid does not escape from the main chamber through the nozzle inlet. Preferably, the seal may be configured such that the nozzle and the seal are in a slidable relationship.

[0024] Typically, the main chamber may include walls with a flexible membrane. In use, the flexible membrane provides a surface for contact with the patient. Preferably, the flexible membrane can substantially conform to the shape of the portion of the body in contact with the patient.

[0025] Typically, flexible membranes can be made from materials selected from the group consisting of elastomers and thermoplastics.

[0026] In some embodiments, the main chamber may have a single-walled configuration, comprising a relatively flexible wall, preferably a relatively flexible polymer membrane. Preferably, the relatively flexible wall may be flexible enough to substantially conform to the shape of the patient portion in contact with it and to transmit the pressure of fluid entering the main chamber to the patient's surface.

[0027] The membrane can be made of materials selected from thermoplastics (polyethylene, polypropylene, polyvinyl chloride) and elastomers. Siloxane elastomers are particularly preferred. The outer surface of the flexible membrane can be textured. Textured surfaces can be used to improve the patient's grip on the flexible membrane surface and reduce the likelihood of slippage.

[0028] In a single-wall embodiment, fluid entering the main chamber can engage with the inner surface of a portion of the main chamber wall that comes into contact with the patient.

[0029] In an alternative embodiment, the main chamber may have a double-walled configuration, comprising a relatively elastic inner wall surrounded substantially by a relatively inelastic outer wall. The inner wall preferably comprises a relatively elastic polymer membrane. Preferably, the inner wall may be flexible. The membrane may be made of a material selected from thermoplastics (polyethylene, polypropylene, polyvinyl chloride) and elastomers. Siloxane elastomers are particularly preferred.

[0030] The outer wall can be relatively inelastic. Preferably, the outer wall can be a flexible membrane. Advantageously, this allows the outer wall to substantially conform to the shape of the patient portion it contacts, while enclosing and supporting the inner wall. The outer wall can advantageously prevent the inner wall from sliding on the patient's surface, particularly in embodiments where the main chamber has a large volume, for example, greater than 4 liters. Because the outer wall can be substantially inelastic, it helps maintain the structure of the main chamber and can support at least a portion of the fluid weight. Therefore, the outer wall allows the user to control the amount of fluid weight applied to the patient's surface.

[0031] Preferably, the inner wall can slide in contact with the outer wall. Alternatively, the inner wall can be fixedly in contact with the outer wall.

[0032] Preferably, the outer wall can be detachably attached to a relatively rigid portion of the main chamber via an attachment device, allowing the outer wall to be removed from the device. Those skilled in the art will understand that many suitable attachment devices exist that allow the outer wall to be detachably attached to a relatively rigid portion. For example, attachment devices may include hook fasteners, snap-fit ​​fasteners, screws, push-button fasteners, zipper fasteners, or threaded fasteners such as nuts and bolts.

[0033] The outer wall can be designed for single use, thus allowing it to be removed and replaced after each use of the device. Advantageously, this eliminates the need for cleaning the outer wall, thereby improving hygiene.

[0034] The use of embodiments with a double-walled main chamber is largely similar to that of embodiments with a single-walled main chamber, except that the fluid entering the main chamber can engage a portion of the inner surface of the inner wall of the main chamber, such that the pressure of the fluid entering the main chamber is transmitted through the inner wall to the outer wall providing contact with the patient, reaching the surface of the patient to be treated.

[0035] In some embodiments, the main chamber may further include one or more expandable support members. Each of the one or more expandable support members is in fluid communication with the main chamber. For the purposes of this invention, expandable means that the support member can be filled with a fluid, which may be a liquid, such as water.

[0036] One or more expandable support members may include a foldable frame.

[0037] One or more expandable support members may comprise generally tubular members, pouches, or other expandable structures. Preferably, the expandable support member comprises one or more generally tubular members. For the purposes of this invention, the generally tubular member may have a non-circular cross-section; however, it may also be circular. Similarly, the area of ​​the cross-section may vary or remain constant along the length of the generally tubular member. Generally, references to the shape of the expandable support member refer to its shape when substantially fully expanded.

[0038] One or more expandable support members may include a first opening located at or toward a first end of the expandable support member, and a second opening located at or toward a second end of the expandable support member. Preferably, the second end is closer to the surface for contacting the patient than the first end. The first and second openings may be in fluid communication with the main chamber, for example, in the form of an opening in the outer wall of the main chamber.

[0039] Typically, the first opening is located near the fluid inlet of the main chamber. The main chamber may include a surface for contacting the patient. Preferably, the second opening is positioned toward the surface for contacting the patient.

[0040] Typically, one or more expandable support members are directly connected to the outer wall of the main chamber, preferably to the inner or outer surface of the outer wall of the main chamber. Most preferably, one or more expandable support members are directly connected to the inner surface of the outer wall of the main chamber. In embodiments including a double-walled main chamber, preferably, one or more expandable support members can be directly connected to the innermost wall defining the main chamber, more preferably to the inner surface of the innermost wall defining the main chamber. One or more expandable support members can be directly connected by adhesives, stitching, thermal or acoustic welding, or other methods.

[0041] Typically, the device includes about 1 to about 10 expandable support members. Preferably, the device includes about 2 to about 6 expandable support members, such as 4 expandable support members.

[0042] In embodiments including multiple expandable support members, two or more of the expandable support members may be connected, or they may be separate. Preferably, each expandable support member is separate from the other expandable support members. That is, each expandable support member may be separated from adjacent support members by a region of the outer wall of the main chamber.

[0043] Typically, one or more expandable support members are located between the inlet and the surface used for contact with the patient.

[0044] Typically, one or more expandable support members are arranged to extend from the fluid inlet toward the surface in contact with the patient, with a first end of the expandable support member positioned close to the fluid inlet. Preferably, all expandable support members are configured to extend from the fluid inlet toward the surface in contact with the patient. Typically, the expandable support members are spaced substantially uniformly around the fluid inlet.

[0045] Typically, one or more expandable support members are configured such that, during use, fluid entering the main chamber can flow along the longitudinal length of the expandable support member into a first opening of at least one expandable support member and out through a second opening. Preferably, the fluid entering each expandable support member from the fluid inlet can generate a local pressure increase relative to the fluid pressure within the main chamber. This local fluid pressure can cause one or more expandable support members to inflate and provide increased structural stiffness to the main chamber.

[0046] Advantageously, this increased structural stiffness can provide improved support for the chamber when the device is in use and / or when it is repositioned on the patient. This makes it easier for the user to manually move the device. The expandable support member can be thought of as providing a skeletal structure to the main chamber.

[0047] When fluid flow ceases within the chamber, the local pressure within the expandable support member decreases, causing it to vent. The fluid within the expandable support member can then exit through a second opening and / or a first opening. During venting, the expandable support member provides minimal structural stiffness to the main chamber.

[0048] The size and / or shape of the second opening can be configured to ensure that each expandable support member provides sufficient support to the main chamber. For the purposes of this invention, sufficient support may depend on the number of expandable support members, their dimensions, and their arrangement within the main chamber. Preferably, the second opening may have a smaller cross-sectional area than the first opening. The exact construction and size of the first and / or second openings can be selected based on the stiffness required to be provided by each expandable support member.

[0049] The first and / or second opening of each expandable support member may include an orifice or a valve. For example, the valve may include a check valve or a slit valve. Preferably, the first opening may include a check valve and / or the second opening may include a slit valve.

[0050] In embodiments where the expandable support members are typically tubular, each typically tubular member can be substantially tubular or substantially conical. For example, the cross-sectional area of ​​the substantially tubular member can decrease between the first opening and the second opening.

[0051] Typically, one or more expandable support members are each in the form of an expandable chamber defined by at least one wall. The wall of each expandable chamber may form part of the outer wall of the main chamber. Preferably, the wall defining the expandable chamber may be substantially tubular.

[0052] Typically, the walls of the main chamber comprise a flexible membrane. The expandable support member may comprise the same material as the flexible membrane of the main chamber. Typically, the expandable support member may be made of a material selected from elastomers, thermoplastics, and combinations thereof.

[0053] In one embodiment, the fluid inlet may include a fluid inlet nozzle. The inlet may be configured such that the distance from the fluid inlet nozzle to the surface for contacting the patient is variable.

[0054] In embodiments where the inlet is configured such that the distance from the fluid inlet nozzle to the surface in contact with the patient is variable, the position of the fluid inlet nozzle can be used to control fluid inflow into one or more expandable support members. Preferably, when the fluid inlet nozzle retracts toward the nozzle inlet, the fluid inflow into one or more expandable support members may increase, thereby causing the expandable support members to expand. Conversely, when the fluid inlet nozzle is further inserted into the main chamber, the fluid inflow into one or more expandable support members may decrease. This may cause one or more expandable support members to deflate.

[0055] Advantageously, such an embodiment allows the operator of the device to manually control the stiffness of the expandable support member. Therefore, the inlet nozzle can retract to increase the stiffness of the expandable support member when moving and positioning the main chamber. However, when massaging the patient, the fluid inlet nozzle can be further inserted into the main chamber.

[0056] The specific shape, number, and arrangement of the expandable support components can be selected based on the dimensions of the main chamber. This can be beneficial for designing devices intended to massage specific body parts, such as the back, shoulders, or legs.

[0057] Typically, the device may also include a pump system for supplying fluid to the fluid inlet. Fluid can be supplied to the main chamber through a first pipe, which is connected to the fluid inlet and / or inlet nozzle via a fluid-sealed connector. Fluid can be removed from the main chamber through a second pipe, which is connected to the fluid outlet via a second fluid-sealed connector. Such piping must be able to withstand fluid pressures up to approximately 300 kPa (3 bar). The first and second pipes can be made of flexible materials, such as polyvinyl chloride (PVC) or rubber. Using flexible materials for the first and second pipes simplifies the task of maneuvering the main chamber to different positions during equipment use and also allows for more compact storage when the equipment is not in use.

[0058] The tubes may include a double-walled arrangement, such that they comprise an inner tube made of a waterproof material, surrounded by an outer tube or a sheath made of a more durable material, thereby providing protection for the inner tube. The outer tube, made of a tougher material, helps protect the inner tube from wear, thus extending the service life of the component. For example, such a double-walled arrangement may include an ethylene propylene diene monomer rubber core surrounded by a braided stainless steel sheath. However, those skilled in the art will understand that various combinations of materials can be chosen, as long as they provide the aforementioned properties.

[0059] The first and / or second tubing may each include a releasable connector through which they connect to the main chamber. Therefore, the first and / or second tubing can be detached from the main chamber by the user. The ability to detach the first and / or second tubing from the main chamber provides several advantages, including easy access to the main chamber for maintenance when one or both tubing have been detached. Furthermore, removable tubing provides the ability to replace individual components rather than the entire device in case of damage, while also improving the ease of storage and transport of the equipment.

[0060] The device may include a pump system for supplying pressurized fluid to the main chamber. The pump system may be operatively connected to the main chamber via a first pipe. Suitable pump systems are known to those skilled in the art and include, for example, POLYPROMSYNTESAqua Optimum, TRIBOYO T2, or ULTRAGEL HUNGARY OM 217.

[0061] In one embodiment, fluid exiting the main chamber via the fluid outlet can be recirculated back into the main chamber via the fluid inlet using a pump system. Fluid can flow between the fluid outlet and the fluid pump system via a second conduit. This fluid recirculation around the device advantageously allows it to operate as a closed system. This improves the device's portability and makes it operable virtually anywhere, such as in a patient's home. It also keeps the fluid within the device throughout use, ensuring that the user and patient are never exposed to the fluid at any point during operation.

[0062] The fluid pump system may also include means that allow the user to change the fluid pressure and thus the speed at which the fluid is propelled through the first tube and into the main chamber. This allows the user to adjust the intensity of the massage.

[0063] Alternatively, the device may include means for connecting the main chamber to a tap water supply, such as a hose that can be connected to a faucet.

[0064] The temperature of the fluid within the device can vary between approximately 5°C and approximately 42°C. Preferably, the user can change the temperature of the fluid within the device. This ability to change the temperature of the fluid within the device provides a range of therapeutic benefits because the temperature of the fluid within the device will affect the temperature of the patient area to which treatment is being applied.

[0065] By using a fluid with a temperature below 15°C, preferably below 10°C, the patient area being massaged can also be cooled. This can provide therapeutic effects, such as reducing inflammation and relieving pain. Conversely, by using a fluid at or above body temperature within the device, preferably up to about 42°C, the temperature of the patient area being massaged will be raised. This can promote blood flow to the area and / or relax surrounding muscles.

[0066] Preferably, the device may further include a temperature management system. This temperature management system may include a thermostat, preferably configured to measure and maintain the fluid temperature within the device within ±2°C of a user-preselected temperature. The temperature management system may also include an interface with a screen displaying the measured temperature of the fluid within the device. Preferably, the screen may also display information such as the selected temperature of the fluid within the device and the pressure of the fluid within the device. The interface may also be configured to allow the user to change the temperature of the fluid within the device.

[0067] The fluid contained within the apparatus may preferably include water. The fluid may also include a mixture of water and one or more other fluids. Those skilled in the art will understand that other fluids / mixtures may be used. When the fluid is a liquid, it is preferably substantially free of air bubbles.

[0068] The device may include an integrated handle configured to facilitate manipulation, transport, and support of the main chamber. The integrated handle may be coupled to the main chamber via one or more movable joints, or alternatively, may be rigidly coupled to the main chamber, for example, by forming an integral structure with a relatively rigid portion of the main chamber.

[0069] As discussed, the main chamber may include a relatively rigid portion and a relatively flexible portion, wherein the relatively rigid portion includes a fluid inlet and / or a fluid outlet. The relatively rigid portion may be metallic (copper, stainless steel, aluminum, etc.) or comprise one or more polymers (thermosetting plastics, polycarbonate, etc.) or composite materials, such as glass or carbon-reinforced polymers.

[0070] The device can be operated to massage the user, meaning that, as stated throughout the text, the user and the patient are the same person.

[0071] In another aspect, the present invention provides a method for performing dry massage on a patient, comprising the following steps:

[0072] a. Position the dry massage device, including the main fluid chamber, onto the patient's area to be massaged.

[0073] b. The main chamber is at least partially filled with fluid through the inlet.

[0074] c. Change the direction of fluid entry into the main chamber to massage the patient, while keeping the main chamber surface in contact with the patient essentially still.

[0075] Advantageously, this method ensures that neither the user nor the patient comes into contact with the fluid during normal operation of the device. Furthermore, this method increases the patient area that can be treated without removing or sliding the main chamber.

[0076] Preferably, the step of at least partially filling the main chamber with fluid through the inlet may include filling the chamber volume by more than 50%, preferably more than 70%, more preferably more than 90%, such as 95%. Advantageously, this will reduce the possibility that any air in the main chamber will cause pump malfunction.

[0077] Typically, the method may also include the step of moving a fluid inlet relative to a surface in contact with the patient, while the surface remains substantially stationary in contact with the patient.

[0078] Fluids can typically include water.

[0079] In another aspect, the present invention provides a method for performing dry massage using a dry massage device, the dry massage device including a main chamber having an inlet configured to direct fluid entering the main chamber to a surface of the device in contact with a patient, and an outlet configured to allow fluid to exit the main chamber, wherein fluid exiting the main chamber via the fluid outlet is recirculated to the fluid inlet via a fluid pump system.

[0080] Typically, the method also includes the step of moving the inlet relative to a surface in contact with the patient, while the surface remains substantially stationary in contact with the patient.

[0081] Dry massage devices can be as described in earlier aspects and embodiments of the present invention.

[0082] On the other hand, the present invention provides a dry massage device including a main chamber, which includes an inlet configured to guide fluid into the main chamber in a direction toward a surface of the main chamber that contacts the patient, and a fluid outlet configured to allow fluid to leave the main chamber, wherein fluid leaving the main chamber via the fluid outlet is recirculated back into the main chamber via the inlet through a fluid pump system.

[0083] Typically, the fluid temperature within a dry massage device can be from about 5°C to about 42°C. Preferably, the device may include a temperature management system, and more preferably, a thermostat. Typically, the fluid is a liquid, and preferably, the fluid includes water.

[0084] Typically, the main chamber may include a patient contact surface, and wherein, in use, the fluid inlet may be movable relative to the patient contact surface while the patient contact surface remains substantially stationary.

[0085] In another aspect, the present invention provides a dry massage device comprising a main chamber defined by an outer wall, the outer wall including a surface for contacting a patient. The main chamber includes an inlet configured to allow fluid to enter the main chamber to massage the patient, and an outlet configured to allow fluid to exit the main chamber. The main chamber also includes one or more expandable support members. Each expandable support member is in fluid communication with the main chamber. For the purposes of the invention, expandable means that the support member can be filled with fluid, which can be a liquid or a gas, such as water.

[0086] One or more expandable support members may include a foldable frame.

[0087] Typically, one or more expandable support members may comprise generally tubular members, pouches, or other expandable structures. Preferably, the expandable support member comprises one or more generally tubular members. For the purposes of this invention, the generally tubular member may have a non-circular cross-section; however, it may also be circular. Similarly, the area of ​​the cross-section may vary or remain constant along the length of the generally tubular member. Generally, references to the shape of the expandable support member refer to its shape when substantially fully expanded.

[0088] In some embodiments, one or more expandable support members may include a first opening located at or toward a first end of the expandable support member, and a second opening located at or toward a second end of the expandable support member, preferably closer to a surface for contacting the patient than the first end. The first and second openings may be in fluid communication with the main chamber, for example, in the form of an opening in the outer wall of the main chamber.

[0089] Typically, the first opening is located near the fluid inlet of the main chamber. The main chamber may include a surface for contacting the patient. Preferably, the second opening is positioned toward the surface for contacting the patient.

[0090] Typically, one or more expandable support members are configured such that, during use, fluid entering the main chamber can flow along the longitudinal length of the expandable support member into a first opening of at least one expandable support member and out through a second opening. Preferably, the fluid entering each expandable support member from the fluid inlet can generate a local pressure increase relative to the fluid pressure within the main chamber. This local fluid pressure can cause one or more expandable support members to inflate and provide increased structural stiffness to the main chamber.

[0091] Advantageously, this increased structural stiffness can provide improved support for the chamber when the device is in use and / or when it is repositioned on the patient. This makes it easier for the user to manually move the device. The expandable support member can be thought of as providing a skeletal structure to the main chamber.

[0092] When fluid flow ceases within the chamber, the local pressure within the expandable support member decreases, causing it to vent. The fluid within the expandable support member can then exit through the second and / or first openings of the respective expandable support member. During venting, the expandable support member provides minimal structural stiffness to the main chamber.

[0093] The size and / or shape of the second opening can be configured to ensure that each expandable support member provides sufficient support to the main chamber. For the purposes of this invention, sufficient support may depend on the number of expandable support members, their dimensions, and their arrangement within the main chamber. Preferably, the second opening may have a smaller cross-sectional area than the first opening. The exact construction and size of the first and / or second openings can be selected based on the required stiffness.

[0094] The first and / or second opening of each expandable support member may include an orifice or a valve. For example, the valve may include a check valve or a slit valve. Preferably, the first opening may include a check valve and / or the second opening may include a slit valve.

[0095] One or more expandable support members may have a first opening fluidly connected to the upstream of the inlet, i.e., a location from which fluid can flow into the main chamber. Preferably, the first opening of the one or more expandable support members may include a sealable valve. The sealable valve is operable to switch between a sealed configuration where fluid cannot flow into the first opening from the fluid inlet and a non-sealed configuration where fluid can flow into the first opening from the fluid inlet. Preferably, the sealable valve is user-operable via a switch. The switch may be located on a handle in the main chamber.

[0096] In some alternative embodiments, one or more expandable support members may include a first opening in fluid communication with a region outside the main chamber. Preferably, the first opening is a sealable port or valve through which fluid can enter and / or exit the expandable support member.

[0097] Fluids, such as air, can enter the expandable support member by connecting a fluid pump to a sealable valve or port. Alternatively, the user can inflate the expandable support member by blowing air through a sealable port or valve. Preferably, the sealable valve or port can be sealed once the expandable support member has inflated. To deflate the expandable support member, the sealable valve or port can be unsealed to allow fluid to exit the expandable support member. Multiple expandable support members can be fluidly connected so that they can be collectively inflated and deflated through a single sealable valve or port. Alternatively, each expandable support member can have its own sealable valve or port.

[0098] When inflated, one or more expandable support members provide increased structural stiffness to the main chamber. Advantageously, this increased structural stiffness provides improved support to the chamber during use and / or when the device is repositioned on the patient. This makes it easier for the user to manually move the device. The expandable support members can be thought of as providing a skeletal structure to the main chamber. When deflated, the expandable support members provide very little structural stiffness to the main chamber.

[0099] Typically, one or more expandable support members are directly connected to the outer wall of the main chamber, preferably to the inner or outer surface of the outer wall of the main chamber. Most preferably, one or more expandable support members are directly connected to the inner surface of the outer wall of the main chamber. In embodiments including a double-walled main chamber, preferably, one or more expandable support members can be directly connected to the innermost wall defining the main chamber, more preferably to the inner surface of the innermost wall defining the main chamber. One or more expandable support members can be directly connected by adhesives, stitching, thermal or acoustic welding, or other methods.

[0100] Typically, the device includes about 1 to about 10 expandable support members. Preferably, the device includes about 2 to about 6 expandable support members, such as 4 expandable support members.

[0101] In embodiments including multiple expandable support members, two or more of the expandable support members may be connected, or they may be separate. Preferably, each expandable support member is separate from the other expandable support members. That is, each support member can be separated from adjacent support members by a region of the outer wall of the main chamber.

[0102] Typically, one or more expandable support members are located between the inlet and the surface used for contact with the patient.

[0103] Typically, one or more expandable support members are arranged to extend from the fluid inlet toward the surface in contact with the patient, with a first end of the expandable support member positioned close to the fluid inlet. Preferably, all expandable support members are configured to extend from the fluid inlet toward the surface in contact with the patient. Typically, the expandable support members are spaced substantially uniformly around the fluid inlet.

[0104] In embodiments where the expandable support members are typically tubular, each typically tubular member can be substantially tubular or substantially conical. For example, the cross-sectional area of ​​the substantially tubular member can decrease between the first opening and the second opening.

[0105] Typically, one or more expandable support members are each in the form of an expandable chamber defined by at least one wall. The wall of each expandable chamber may form part of the outer wall of the main chamber. Preferably, the wall defining the expandable chamber may be substantially tubular.

[0106] Typically, the walls of the main chamber comprise a flexible membrane. The expandable support member may comprise the same material as the flexible membrane of the main chamber. Typically, the expandable support member may be made of a material selected from elastomers, thermoplastics, and combinations thereof.

[0107] In an embodiment, and as described above, the inlet may include a fluid inlet nozzle. The inlet may be configured such that the distance from the fluid inlet nozzle to the surface for contacting the patient is variable.

[0108] In embodiments where the inlet is configured such that the distance from the fluid inlet nozzle to the surface in contact with the patient is variable, the position of the fluid inlet nozzle can be used to control fluid inflow into one or more expandable support members. Preferably, when the fluid inlet nozzle retracts toward the nozzle inlet, the fluid inflow into one or more expandable support members may increase, thereby causing the expandable support members to expand. Conversely, when the fluid inlet nozzle is further inserted into the main chamber, the fluid inflow into one or more expandable support members may decrease. This may cause one or more expandable support members to deflate.

[0109] Advantageously, such an embodiment allows the operator of the device to manually control the stiffness of the expandable support member. Therefore, the inlet nozzle can retract to increase the stiffness of the expandable support member when moving and positioning the main chamber. However, when massaging the patient, the fluid inlet nozzle can be further inserted into the main chamber.

[0110] The specific shape, number, and arrangement of the expandable support components can be selected to provide the specific shape of the main chamber. This can be beneficial for designing devices configurable for massaging specific body parts (such as the back, shoulders, or legs).

[0111] In another aspect, the present invention provides a method for performing dry massage, comprising the steps of: providing a device according to any of the foregoing aspects, placing the device on the patient's treatment area, and massaging the patient through the device.

[0112] The dry massage device may also include features disclosed in earlier aspects and embodiments of the invention. Attached Figure Description

[0113] Preferred features of the invention will now be described by way of example with reference to the accompanying drawings, in which:

[0114] Figure 1 A dry massage device according to the present invention is shown.

[0115] Figure 2 A second embodiment of the dry massage device according to the invention is shown, which includes means for adjusting the penetration depth of the inlet nozzle.

[0116] Figure 3A and Figure 3B The invention illustrates moving the fluid inlet relative to the surface in contact with the patient to alter the area being massaged.

[0117] Figure 4A dry massage device that can be operatively connected to a fluid pump system according to the present invention is shown.

[0118] Figure 5 A dry massage device with a double-walled main chamber structure is shown.

[0119] Figures 6A to 6E A dry massage device with one or more expandable support members is shown. Detailed Implementation

[0120] refer to Figure 1 This invention provides a dry massage device including a main chamber 1. The main chamber 1 includes an inlet 2 through which fluid enters the main chamber. The main chamber 1 also includes an outlet 3 through which fluid exits the main chamber. The main chamber 1 further includes a surface 4 for contacting a patient; in the illustrated example, this surface contacts a patient 5, specifically a portion of the patient's leg. In this example, the direction of the fluid 6 entering the main chamber can be changed by the user altering the angle of the fluid inlet nozzle 7 relative to the surface for contacting the patient. Therefore, the direction of the fluid entering the main chamber can be changed, while the surface 4 for contacting the patient remains substantially stationary relative to the patient 5.

[0121] Typically, the fluid is a liquid, usually a liquid containing water (e.g., an aqueous solution). In embodiments, the water may contain an antifreeze agent that lowers the freezing point of the aqueous solution. Examples of suitable antifreeze agents include methanol, ethylene glycol, propylene glycol, and glycerol.

[0122] The fluid entering the chamber is typically supplied at pressure from a pump system in fluid communication with the fluid inlet. The pump system typically supplies fluid at pressures ranging from approximately 50 kPa (0.5 bar) to approximately 150 kPa (1.5 bar). Generally, the pressure of most of the fluid in the chamber is approximately atmospheric pressure. Therefore, the velocity (by weight) of the fluid leaving the main chamber through the fluid outlet is substantially the same as the velocity of water entering the main chamber through the fluid inlet.

[0123] Typically, dry massage systems, including the pump system, are closed systems in use. Fluid leaving the main chamber via the fluid outlet is usually recirculated back to the fluid inlet via the pump system and returned to the chamber. This allows dry massage systems to be used in a wider range of locations, such as away from water sources, hospital wards, or even patients' homes.

[0124] In the illustrated example, the main chamber has a single-walled structure consisting of two parts: a relatively rigid portion 8, comprising a metallic material and / or a relatively rigid polymer, and a relatively flexible membrane 9. The relatively flexible membrane may comprise a material selected from the group consisting of thermoplastics, rubber, or elastomers. Siloxane-based elastomer membranes are particularly preferred. As shown, the relatively rigid portion 8 may include a fluid inlet 2 and a fluid outlet 3. Typically, the relatively rigid portion is designed to provide structural support to the main chamber and facilitate the user in changing the direction of fluid entry into the main chamber. In the illustrated embodiment, the surface 4 for contacting the patient 5 is located outside the relatively flexible membrane. In use, the fluid jet entering the chamber is directed toward the opposite side of the flexible membrane, including the portion that contacts the patient.

[0125] Typically, relatively flexible membranes have a thickness of about 0.25 mm to about 2 mm, more preferably about 0.5 mm to about 1 mm.

[0126] During use, the direction of the fluid 6 entering the main chamber can be controlled by the user. Typically, the fluid is directed towards the opposite side of the main chamber wall, which contacts the patient. Therefore, the pressure of the fluid jet exiting the fluid inlet is transmitted to the patient 5 with a massage effect. The user can change the direction of the fluid 6 entering the main chamber to alter the area of ​​the surface 4 that the fluid is directed to, while maintaining essentially static contact with the patient. Advantageously, this allows for massaging a larger area of ​​the patient without having to move the main chamber.

[0127] For the purposes of this invention, "still" means that the surface 4 used to contact the patient does not move significantly relative to the patient 5.

[0128] like Figure 2 As shown, the main chamber 1 has a single-walled structure and includes a relatively flexible membrane 9 that bends to conform to the shape of the part of the patient 5 it contacts when in contact with the patient. In this example, the user can change the depth of the fluid inlet nozzle 7 within the main chamber 1 by inserting it longitudinally into or retracting it from the main chamber 1. This action increases or decreases the distance between the fluid inlet nozzle and the surface 4 used to contact the patient, respectively. By changing this distance, the pressure of the fluid applied to the inner surface of the main chamber 1 can be increased or decreased, thereby increasing or decreasing the intensity of the massage applied to the patient.

[0129] In the exemplary system, the integrated handle 10 is connected to the main chamber 1. This allows the user to more easily manipulate the position of the main chamber relative to the patient. The integrated handle 10 includes a fluid outlet through which fluid exits the main chamber 1. In some embodiments (not shown), the integrated handle may include multiple fluid outlets, such as two, located in the area where the integrated handle 10 meets the relatively rigid portion 8, through which fluid exits the main chamber 1.

[0130] refer to Figure 3A The main chamber 1 is located on the patient 5. Fluid enters the main chamber 1 through the fluid inlet 2 under pressure from a pump system (not shown). The fluid 6 entering the main chamber is directed toward the inner surface of a portion of the flexible membrane 9, which in this case is the surface 4 for contacting the patient. Fluid pressure is transmitted to the patient through the flexible membrane 9, which provides a massage effect. The fluid exits the main chamber through the fluid outlet 3 located in the rigid portion 8 to be recirculated by the pump system (not shown). An integrated handle 10 is also included relative to the rigid portion 8.

[0131] Figure 3B The position of the fluid inlet 2 has been moved along direction (C). As the rigid portion moves along direction (C), the flexible membrane 9 rolls over the patient; however, the surface 4 in contact with the patient remains in continuous contact with the patient 5 and is essentially stationary relative to the patient 5. Due to the repositioning of the fluid inlet 2 relative to the patient, the fluid 6 entering the main chamber is directed to different portions of the inner surface of the flexible membrane 9, thereby directing it to different areas of the patient. Advantageously, this allows the user to change the area of ​​the patient 5 being massaged without having to slide the main chamber across the patient's skin.

[0132] Figure 4 The main chamber 1 connected to the fluid pump system 13 is shown. Fluid enters the main chamber 1 through the fluid inlet 2 in the rigid portion 8 of the main chamber 1. The illustrated system is a closed system in use, although it may be emptied and refilled for transport and storage purposes. The main chamber, inlet, and outlet are shown as follows. Figure 3A As shown, and numbered accordingly.

[0133] After leaving the main chamber 1 through fluid outlet 3, the fluid is drawn along a first pipe 14, one end of which is connected to fluid outlet 3 and the other end to fluid pump system 13. The fluid is then pumped under pressure by fluid pump system 13 through a second pipe 15, one end of which is connected to fluid pump system 13 and the other end to fluid inlet nozzle 7. Thus, the fluid is recirculated.

[0134] Figure 5 A main chamber 1 with a double-walled structure is shown. The main chamber 1 includes a relatively elastic inner wall 19, which is substantially surrounded by a relatively inelastic outer wall 16. Both the inner wall (19) and the outer wall (16) are flexible. The outer wall 16 includes an attachment device 17 having a support 18 connected to a relatively rigid portion 8 of the device. The attachment device 17 also serves as a handle for operating the device.

[0135] Figures 6A to 6E Various views and embodiments are shown, in which the main chamber 1 includes an expandable support member 20. In these embodiments, the expandable support member 20 is a generally tubular member 21.

[0136] Figure 6A A top view of the main chamber 1 is shown, in which the expandable support member 20 comprises four generally tubular members 21. Each generally tubular member 21 has a first end near the pump inlet and a second end near the surface for contact with the patient 5. In this embodiment, fluid entering the main chamber 1 does not directly enter the generally tubular members 21. Therefore, the expandable support member does not provide increased structural stiffness to the main chamber 1.

[0137] Figure 6B Showing Figure 6A A side view of the device. It can be seen that the fluid entering the main chamber 1 is not directed into the generally tubular component 21. Therefore, there is no localized pressure increase in the generally tubular component 21, thereby maximizing the surface area of ​​the surface in contact with the patient 5. In this configuration, the user has maximum freedom to manipulate the fluid inlet nozzle 23 to direct fluid across the entire area of ​​the surface used for contact with the patient 5.

[0138] A fluid inlet nozzle 23 is inserted through a relatively rigid portion 24 of the main chamber 1. The fluid inlet nozzle 23 and / or the entire relatively rigid portion 24 can move generally toward and away from the surface used to contact the patient. This is indicated by directional arrows 25. By moving the fluid inlet nozzle 23 and / or the relatively rigid portion 24, the intensity of the massage can be changed by the user.

[0139] Figure 6C and Figure 6D Shown from the top view and side view Figure 6A and Figure 6B The device contains a generally tubular member 21 into which fluid is directed. It can be seen that the fluid entering the generally tubular member 21 creates a localized pressure increase within the expandable support member 20. This reduces the surface area 22 available for contact with the patient, but makes the device easier for the user to operate manually.

[0140] A fluid inlet nozzle 23 is inserted through a relatively rigid portion 24 of the main chamber 1. The fluid inlet nozzle 23 and / or the entire relatively rigid portion 24 can move generally toward and away from the surface used to contact the patient. By moving the fluid inlet nozzle 23 and / or the relatively rigid portion 24, the intensity of the massage can be changed by the user.

[0141] Figure 6E An apparatus is shown comprising an expandable support member 20, which comprises a generally tubular member 21 with a different configuration. This thus alters the shape of the main chamber, making it, for example... Figures 6A to 6D Those are longer and narrower. This allows the shape of the device to be customized to provide massage to specific areas of the body.

[0142] It should be understood that various modifications can be made to the illustrated embodiments without departing from the spirit and scope of the invention as defined by the appended claims, as interpreted under patent law.
