Description

[0001] A HANDHELD APPARATUS WITH A MEDIA DISPENSER AND A METHOD THEREOF

[0002] Technical Field

[0003] The present invention generally relates to handheld treatment devices. More particularly, the present invention relates to handheld devices equipped with a technological treatment head, such as ultrasound, RF or massaging, used across a spectrum of applications including medicine, cosmetics, body shaping, wound treatment, pain relief, blood flow stimulation, skin treatments, spa therapy, and others.

[0004] Background

[0005] As of today, handheld devices with technological heads are widely used in medicine, cosmetics, body shaping, wound treatment, pain relief, blood flow stimulation, skin treatments, spa therapy, and others., which require coupling medium to facilitate proper contact between the device and the skin. However, existing methods of delivering the coupling medium lack automation and sterility. Accordingly, there is a need for an improved system and method that provides automated means of applying the coupling medium, while using the handheld device.

[0006] US 11,938,347, by the same inventor, discloses a hand-held ultrasound apparatus having a transducer. The disclosed transducer is whirled by an electric actuator, while the operator holds the ultrasound apparatus, and aims the transducer to the body of the patient. As disclosed, the ultrasound transducer is whirled, in circles, while applying the ultrasound waves to the body of the patient. Thus, the transducer efficiently disperses the ultrasound waves over an area larger than the transducer’s initial Effective Radiating Area (ERA). Nevertheless, the publication does not disclose the use of a coupling medium to facilitate contact between surfaces, for ensuring energy penetration while preventing reflection.

[0007] US4844080 discloses a device where a coupling agent can be dispensed from a reservoir to the site of the diagnostic probe. As disclosed, the device comprises a reservoir for the coupling agent, a hose line from the reservoir to the site of the diagnostic probe, such as the sound head, as well as a device for conveying the coupling agent, such as a pump or a reservoir under pressure. Nevertheless, the disclosed device does not ensure sterility between sessions of different patients without extensive cleaning procedure and disposing all of the remaining medium in reservoir.

[0008] US20090093723 discloses an ultrasound device, comprising a housing, an ultrasound transducer disposed within the housing and having a wear layer, at least one lubricant dispensing port formed on one of the housing and the wear layer, a lubricant reservoir operably connected to the at least one lubricant dispensing port, a pump in fluid connection with the lubricant reservoir, the pump dispensing lubricant from the reservoir through the dispensing port, and a pump actuator operably connected to the pump and controlling the pump. Nevertheless, the disclosed device does not ensure sterility between sessions of different patients without extensive cleaning procedure and disposing all of the remaining medium in reservoir.

[0009] It would therefore be desired to propose a method void of these deficiencies. Summary

[0010] It is an object of the present disclosure to provide a handheld apparatus equipped with a treatment head and equipped with an automated media dispenser and a method thereof.

[0011] It is another object of the present disclosure to provide an ultrasound apparatus that disperses ultrasound waves over an area larger than the transducer’s initial ERA on the skin of a patient, while dispensing coupling media, on the skin of the patient, at the required location, at an appropriate timing, and at the right amount.

[0012] It is still another object of the present disclosure to provide a method for automatically dispensing media, while using a handheld apparatus on the skin of patients, that does not compromise the sterility of the apparatus when used for different patients.

[0013] It is still another object of the present disclosure to provide a handheld apparatus with an automated media dispenser where the media type can be replaced easily, quickly, and foolproof, without preparation and without sterilization.

[0014] It is still another object of the present disclosure to provide a handheld apparatus with several automated media dispensers.

[0041] Detailed Description

[0042] The indefinite articles “a,” “an,” and “the” include plural referents unless clearly contradicted or the context clearly dictates otherwise. The term “comprising” is an open-ended transitional phrase. A list of elements following the transitional phrase “comprising” is a non-exclusive list, such that elements in addition to those specifically recited in the list can also be present. The phrase “consisting of’ limits the composition of a component to the specified materials and excludes any material not specified.

[0043] The terms of “front”, “rear”, “down”, “up”, “bottom”, “upper”, “horizontal”, “vertical”, "right", "left" or any reference to sides or directions are used throughout the description for the sake of brevity alone and are relative terms only and not intended to require a particular component orientation.

[0044] As used herein “sterile” is intended to include free of contagious skin diseases which are spread through moisture contact, such as viruses, bacteria, fungi, protozoa or parasites.

[0045] Handheld apparatuses with transducers, such as ultrasound transducers, massage transducers, RF transducers, or other electrically driven technological heads for treatment, typically necessitate coupling medium to facilitate contact between surfaces, e.g. between the surface of the transducer and the surface of the skin of the patient. For example, in the case of a massage apparatus, where the massage transducer is applied and moved over the skin of the treated area of the body of a patient, oil, or other mediums are needed to facilitate the contact between the surface of the massage transducers and the surface of the skin of the patient during movement. For example, in the case of an ultrasound apparatuses the ultrasound waves are applied to the patient via the ultrasound transducer, by directly applying the ultrasound transducer on the skin of the treated area of the body. However, the Effective Radiating Area (ERA) of the ultrasound transducer is very slim. Thus, in order to apply an equal amount of energy to an area larger than the ERA of the ultrasound transducer the ultrasound transducer needs to be moved within a constant speed throughout the treated area. Nevertheless, ultrasound energy transmission necessitates a coupling medium to facilitate contact between surfaces, e.g. between the surface of the ultrasound transducer and the surface of the skin of the patient, ensuring energy penetration instead of reflection. As human skin is not a “polished” surface, even the closest proximity of the ultrasound transducer to the skin still reveals many gaps which serve as wave reflectors, preventing the penetration of some of the ultrasound energy waves. Thus, the operator is required to add coupling media, between the surface of the ultrasound transducer and the surface of the skin of the patient, for filling these gaps and reducing the energy loss. Nevertheless, excessive amount of coupling media will bother the patient, especially during the facial treatment, while shortage of media will reduce the efficacy of the treatment. Therefore, during the treatment process, coupling media needs to be constantly added at the right amount, e.g. without creating an overflow mess, while moving the transducer over the skin of the patient, and preferably automatically, as manual media application creates an additional load on the operator.

[0046] Fig. 1 is a diagram of the handheld apparatus with an electrical driven transducer and a media dispenser according to some embodiments. According to some embodiments, the apparatus 100 may be a handheld ultrasound apparatus having a media container 213, with a jet-pump 214, that can be actuated for media dispensation. According to some embodiments the media container 213 is an airless media container as they may provide better content preservation even after they are opened. According to some embodiments, the ultrasound apparatus drives an electric actuator, which whirls the ultrasound transducer 101 on the skin of the patient, for dispersing the ultrasound waves over an area larger than the Effective Radiating Area (ERA) of the transducer 101, while dispensing coupling media, from the media container 213, at the required location, at an appropriate timing, and at the right amount, on the skin of the patient. When the operator holds the ultrasound apparatus 100, by gripping the handle, and operates the transducer 101, e.g. on the skin of a patient, the ultrasound transducer 101 may be whirled, in loops, while the coupling media is dispensed from the container 213, through the jet-pump 214, to the required location, e.g. in close proximity to the ultrasound transducer 101, where the whirling transducer 101 is constantly moved over the dispensed media and the treated area, for minimizing energy loss, such as described below in relations to Fig. 9, for example.

[0047] According to some embodiments the apparatus 100 may be a handheld massage apparatus having a media container with a jet-pump that can be actuated for oil dispensation, similar to the described in relations to Fig. 1. According to some embodiments, the apparatus 100 drives an electric actuator, which whirls the massage transducer on the skin of the treated area of the body of a patient while dispensing oil, or other media content, from the media container 213, at the required location, at an appropriate timing, and at the right amount, on the skin of the patient. When the operator holds the apparatus 100, by gripping the handle, and operates the massage transducer, e.g. on the skin of a patient, the massage transducer may be whirled, in loops, while the oil is dispensed from the container 213, to the required location, e.g. in close proximity to the massage transducer, where the whirling massage transducer is constantly moved over the dispensed media and the treated area.

[0048] Fig. 2a is a diagram of an airless media container assembly, according to some embodiments. According to some embodiments, the airless container 213 comprises a built-in jet-pump 214 and a jet diffuser. According to some embodiments, the airless container 213, as described in relations to Fig. 1, also comprises an electronic tag for contactless identification, where the contactless identification protocol maybe incorporated into the apparatus, and actuated by the apparatus. According to some embodiments, the airless container 213 may comprise an NFC identifier to correctly identify the container and the media within it. According to some embodiments, the airless container 213 may also comprise a keyway notch 216 cut in the airless container body in order to prompt the correct instalment of the container in the right angle within the apparatus, e.g. for correctly positioning the NFC identifier in relations to the apparatus.

[0049] Fig. 2b is a cutaway diagram of an airless media container assembly, according to some embodiments. For the sake of brevity, the drawing depicts the inner parts of the airless media container 213, as described in relations to Fig 2a, where the airless container 213 comprises a built-in jet-pump 214 and a jet diffuser 254, according to some embodiments.

[0050] Fig. 3 is a diagram of the top part of the handheld apparatus, displaying the correct instalment of the container within the handheld apparatus, according to some embodiments. For the sake of brevity, the drawing depicts the top side of the media container 213, as described in relations to Fig 2a, where the key way notch 216, of the body of the container 213, is aligned with a protrusion from the handheld apparatus.

[0051] Fig. 4 is a diagram of some of the inner parts of the handheld apparatus, with an electrical driven ultrasound transducer and a media dispenser, according to some embodiments. The ultrasound transducer 101, may be whirled by the electric actuator 200 for treating the skin of a patient, while the media dispenser dispenses coupling media, for minimizing energy loss, and at the right amount, e.g. without creating an overflow mess, on the skin of the patient. The actuator 200 may be an electric motor, e.g. brush or brushless, a stepper motor, or servo motor, solenoid, an angular actuator, a linear actuator, or any other actuator capable of whirling the transducer 101. In some embodiments, the actuator 200 may whirl the transducer 101 in a circular pattern in any direction, or in any other angular pattern. In some embodiments, the actuator 200, may drive, e.g. spin, the cam 201, where the cam 201 comprises a lobe 201a which is attached eccentrically, for spinning in an eccentrical orbit, and for whirling the transducer 101. The transducer 101 is pivotally attached to the lobe 201a, of the cam 201, and attached with an offset of the cam 201 axis of rotation. Thus, when the actuator 200 drives the cam 201, the cam 201spins with its eccentrically placed lobe 201a making circular eccentric movements, and whirls the base 109 of the transducer 101 causing the transducer 101 to whirl in a loop around the rotation axis of cam 201.

[0052] Fig. 5 is a diagram of an exploded view of some of the inner parts of the handheld apparatus with an electrical driven ultrasound transducer and a media dispenser, according to some embodiments. According to some embodiments, electric actuator 200 drives the cam 201 that comprises a threaded hole, placed with an offset of the cam’s axis of rotation, where a threaded pin 202 may be inserted into it. The transducer 101 may be pivotally attached to the threaded pin 202 at its centre of rotation. According to some embodiments, coaxial cable 203 is attached to the base of transducer 101 and creates a free hanging hook that does not stretch the cable 203 when the transducer 101 is whirled. Stabilizer pin 204 may be stationary, within the assembly of the handheld apparatus, and its head may be located within the stabilizing slot 101a, attached to the transducer base. When the actuator 200 rotates the attached cam 201, the threaded pin 202, which is offset in relation to the axis of rotation of the eccentric cam 201, moves in loops and thus drives the pivotally attached transducer 101 in loops. During the whirling of the transducer body 101 in loops, the stabilizing slot 101a slides on the head of the stabilizing pin 204 for limiting the rotation angle of the transducer 101 and preventing rupture of the coaxial cable 203 attached to the base of the transducer 101. Thus, the continuous electrical connectivity to the transducer 101 is secured while allowing it to make many rotations in a circular pattern without excessive distortion of the electrical conductor. The apparatus may also comprise a magnet indicator 205 and a magnetic sensor 206 for correctly indicating the circular position of the cam 201. The apparatus also comprises a fork-cam 209 pivotally connected by its axle 208 to the apparatus, and positioned for pressing the jet-pump 214 of the media container 213 and an electric positioner 210, e.g. a solenoid with its movable pin core 210a. The apparatus also comprises the container 213, with its jet-pump 214, as described below in relations to Fig. 9 for example. According to some embodiments, the apparatus may also comprise a returning spring 207, a PCB circuit 211, and an NFC sticker 212, or any other wireless tag, on the container 213According to some embodiments, the apparatus may be equipped with an NFC reader within its electronic circuitry with an NFC antenna located on its PCB 211. According to some embodiments, the NFC antenna located on the PCB 211 is facing an NFC sticker 212 place on the container 213. The NFC reader circuitry is capable of reading an NFC tag 212 in close proximity thus detecting the presence, or absence, of the container as well, providing said apparatus with additional information recorded on the sticker 212.

[0053] Fig. 6a-6d are diagrams, from an isometric bottom view, showing different phases of the rotation of the cam according to some embodiments. For the sake of brevity, the transducer head has been omitted from the bottom of the diagrams in order to show the different phases of the rotation of the cam 201 without obstruction. As depicted in the diagrams the bottom lobe of the cam 201 is an eccentric where the longest part of the lobe 201 maybe closest to the jet-pump 214, when the transducer base 109 is furthest from jet-pump 214, such as depicted in Fig. 6a for example. On the other hand, the longest part of the lobe maybe far from the jet-pump 214 when the transducer base 109 is closest to the jet-pump 214, such as depicted in Fig. 6b for example.

[0054] Fig. 7 is a diagram of some of the inner parts of the handheld apparatus, with a media dispenser, in its idle state - when no media distribution is occurring, according to some embodiments. When the apparatus is at its idle state, that is the state where the automated media dispenser is not ready yet for dispensing media, the fork-cam 209 is held back in its idle position, for example by the spring 207 hanged on axle 208. When the fork-cam 209 is in the idle position, the rotating eccentric cam 201 does not interact with the forkcam 209 nor with its follower 209a. When the fork-cam 209 is in the idle position the follower 209a, of the fork-cam 209, is located above the surface of the whirling eccentric lobe 201a of the cam 201.

[0055] Fig. 8 is a diagram of some of the inner parts of the handheld apparatus, with a media dispenser, at its operational state - ready for dispensing media, according to some embodiments. According to some embodiments, at first, the electronic circuitry within the apparatus detects when a signal generated by the magnet 205, on cam 201, passes in close proximity to the magnetic sensor 206, where in this position the eccentric lobe 201a of the cam 201 is located far from the jet-pump 214, as described in relations to Fig. 6a. The term “far” it meant to include any position where the longest part of the eccentric lobe 201a is not at its closest position to the jet-pump 214 thereby leaving an empty space of orbit of the eccentric lobe 201a for the follower 209a to partially occupy. At this position, once the signal generated by the magnet 205 is detected in close proximity to the magnetic sensor 206, the apparatus may activate the positioner 210, and the core pin 210a of the positioner 210 may push the left side of the fork-cam 209 downwards forcing the fork-cam 209 to pivot around the axle 208. The angular movement of the fork-cam 209, around the axle 208, drives the follower 209a of the fork-cam 209 into an empty space of orbit of the eccentric lobe 201a of the cam 201, without interacting with the lobe 201a, at this phase, as the lobe 201a is now far away from the jet pump 214.

[0056] Fig. 9 is a diagram of some of the inner parts of the handheld apparatus, with a media dispenser, at its dispensing state - when the media dispenser dispenses media, according to some embodiments. At this phase, when the follower 209a of the fork-cam 209 is pushed into the empty space of orbit of the eccentric lobe 201a of the cam 201, the rotation of the eccentric lobe 201a, pushes the follower 209a of the fork-cam 209, rightwards, in the angular movement, around its axle 208, causing the fork-cam 209 to press the jet-pump 214 of the container 213. By pressing on the jet-pump 214, the jet-pump 214, incorporated in the container 213, releases a droplet of media, e.g. a small amount of media content between 5 to 10 ml. When the positioner 210 is deactivated by the electronic circuitry, of the apparatus, and the rotation of the eccentric lobe 201a continues to rotate effectively causing the lobe 201a to orbit away from the follower 209a of the fork-cam 209, the spring 207 pulls the forkcam 209 back effectively letting the fork-cam 209 to pivot to its idle position, where the following rotation cycles, of the eccentric cam 201a, do not interact with the fork-cam 209 and do not generate media distribution events, as described in relations to Fig. 7 for example. Thus, by dispensing media content, through the jet-pump 214, the apparatus can apply media content to the patient’s skin, at the required location, at an appropriate timing, and at the right amount, without direct contact, thus allowing the usage of the same container for different patients, in a sterile manner, without the danger of contamination. Fig. 10 is a diagram of some of the inner parts of the handheld apparatus, with two media dispensers, according to some embodiments. In some cases, when utilizing the ultrasound’s ability of the transdermal delivery for example, additional active treatment media may be required, in addition to the content media, for specific treatments, such as acne or pigmentation reduction. In some cases, when using a massage transducer, such as transducer 301 for example, several oils and / or treatment medias may be required. In some embodiments, the apparatus may incorporate several dispenser mechanisms and several containers, such as containers 313 and 314, where each of the dispensers may be actuated separately or together, similar to the described in relations to Figs. 7-9, thus further enhancing the variety of the treatment applications and oils. In some embodiments, since the electronic identification on each container may prevent usage of the wrong media, in the case where the apparatus is equipped with several containers, the apparatus can identify the correct dispenser and use it accordingly.

[0057] According to some embodiments, the proposed handheld apparatus with the media dispenser(s), as described above, may be used by the user itself on his own skin.

[0058] While the above description discloses many embodiments and specifications of the invention, these were described by way of illustration and should not be construed as limitations on the scope of the invention. The described invention may be carried into practice with many modifications which are within the scope of the appended claims.
