Description

Technical Field

[0001] This application relates to the field of ultrasound focused cosmetic technology, and in particular to an ultrasound coupling film and its preparation method. Background Technology

[0002] In ultrasound-guided lifting cosmetic surgery, gel coupling agents are typically used for acoustic channel coupling. However, gel-based coupling agents are prone to uneven application, require multiple wipes to remove completely, and dry out easily, resulting in a poor user experience in the medical aesthetics field. Furthermore, the movement of the ultrasound probe compresses the coupling agent, exacerbating uneven application. High-energy ultrasound reflections can also lead to energy loss or over-concentration of energy in certain areas, causing adverse reactions such as redness. Additionally, ultrasound-guided lifting treatments require targeted therapy, which conventional coupling agents cannot achieve. Summary of the Invention

However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.

[0051] In this application, terms such as "further," "even more," and "particularly" are used for descriptive purposes to indicate differences in content, but should not be construed as limiting the scope of protection of this application.

[0054] Traditional ultrasound equipment typically uses gel coupling agents for acoustic channel coupling. However, gel coupling agents are prone to problems during application, such as uneven application, rapid drying, and the need for repeated wiping after use, resulting in a poor user experience in diagnostic, therapeutic, and cosmetic fields. Furthermore, uneven application of the gel coupling agent can lead to energy loss or excessive energy concentration during high-energy focused ultrasound, causing adverse reactions such as skin redness. Additionally, targeted treatment is required during focused ultrasound lifting therapy, a function that traditional gel coupling agents cannot achieve.

[0055] Due to the numerous drawbacks of traditional gel-based coupling agents, an increasing number of manufacturers are opting for ultrasound coupling films. Traditional ultrasound coupling films mostly use agar starch as the primary carrier. These films are relatively brittle and unsuitable for facial areas with specific shapes. Furthermore, during ultrasound lifting treatments, the ultrasound probe directly presses against the skin; variations in pressure and technique among operators lead to differences in treatment depth, resulting in varying treatment outcomes and posing certain risks. Real-time monitoring of skin surface changes, such as redness or adverse reactions, is necessary during focused ultrasound treatment. However, traditional ultrasound coupling films lack transparency.

[0056] For the reasons mentioned above, the inventors improved the ultrasonic coupling film used in ultrasonic focused lifting cosmetic surgery.

[0057] like Figures 1-4 As shown, in a first aspect, this application provides an ultrasonic coupling film 1, which is divided into a first region 10 and a second region 20 on a plane.

[0058] The material of the first region 10 includes ultrasonic coupling material, and the material of the second region 20 includes closed ultrasonic material. The sound transmission effect of the ultrasonic coupling material is greater than that of the closed ultrasonic material.

[0059] This application provides an ultrasonic coupling patch 1, which is divided into a first region 10 and a second region 20 based on whether it corresponds to an ultrasonic focused treatment area. The first region 10 is made of ultrasonic coupling material and can be applied to the ultrasonic focused treatment area for ultrasonic focused treatment. The ultrasonic coupling material is a material with good ultrasonic wave penetration, which can effectively transmit ultrasound in ultrasonic lifting treatment surgery. The second region 20 is made of ultrasonic sealing material and can be applied to non-ultrasonic focused treatment areas. The ultrasonic sealing material is a material that can reduce or even directly block ultrasound transmission in the second region 20, which can effectively reduce the treatment risk in non-treatment areas. The ultrasonic coupling patch 1 provided by this application can overcome many defects of traditional gel coupling agents, such as uneven application, need for multiple wiping, and easy drying. Moreover, the ultrasonic coupling patch 1 divides the treatment area and non-treatment area, indirectly adjusting the position of the ultrasonic focused focal point. When used with an ultrasonic probe for focused lifting cosmetic surgery, it can achieve targeted treatment and targeted strike, which is conducive to improving the treatment effect of ultrasonic focused treatment.

[0060] Furthermore, ultrasound therapy probes are reusable devices, and in actual treatment, it is difficult to guarantee thorough disinfection of the probe after each treatment. The same probe may come into contact with multiple different patients, and if the skin surface of the previous patient has germs or bacteria, cross-infection can easily occur. The ultrasound coupling film 1 provided in this application can provide an isolation barrier between the patient's skin surface and the ultrasound probe, effectively avoiding cross-infection during treatment.

[0061] In some embodiments, the material of the second region 20 further includes an ultrasonic coupling material; within the second region 20, a blocking ultrasonic material covers the surface of the ultrasonic coupling material, or the blocking ultrasonic material is embedded within the ultrasonic coupling material. It is understood that as long as a blocking ultrasonic material is added to the ultrasonic coupling material, whether the blocking ultrasonic material is outside or inside the ultrasonic coupling material, it can effectively block the passage of ultrasonic waves.

[0062] In some embodiments, the ultrasonic coupling material includes a sound-transmitting main material and a solidified carrier, with the sound-transmitting main material encapsulated within the solidified carrier. The sound-transmitting main material is the primary material that transmits ultrasonic waves, while the solidified carrier is the key factor that allows the ultrasonic coupling material to solidify into a solid state. The combination of the sound-transmitting main material and the solidified carrier can form an ultrasonic coupling film 1 with a specific solid shape.

[0063] Furthermore, the acoustically transparent material includes glycerin, carbomer, water, and ethanol. Furthermore, the coagulation carrier includes a polyacrylamide polymer. The ultrasound coupling patch 1, composed of the specific acoustically transparent material and the coagulation carrier, has high transparency, enabling effective observation of the treatment area and skin condition, thus improving the safety of ultrasound treatment and reducing various skin injuries caused by poor coupling or excessive probe pressure. Moreover, the coagulation carrier is made of a highly flexible, low acoustic impedance material, which effectively improves the gel morphology and facilitates shaping.

[0064] In some embodiments, the ultrasound-blocking material includes one or more of sound-absorbing rubber, non-woven fabric, polyethylene, and sound-absorbing silicone. These materials have excellent ultrasound-blocking effects; embedding them within the ultrasound coupling material effectively blocks ultrasound. This area is then applied to the non-ultrasound treatment area, enabling the ultrasound coupling patch 1 provided by this application to achieve targeted planning and targeted ultrasound therapy. It is understood that the ultrasound-blocking material is not limited to the above-mentioned materials; other materials may be used in other embodiments, as long as they can achieve sound blocking, they should be understood as being within the scope of protection of this application.

[0065] In some embodiments, the thickness of the first region 10 is 0.1mm to 5mm, and the thickness of the second region 20 is 0.05mm to 0.3mm. Controlling the thickness of the first region 10 within a specific range allows for better sound transmission, while controlling the thickness of the second region 20 within a specific range helps the enclosed ultrasound material to exert its sound-blocking effect, thereby achieving the effect of targeted therapy. Understandably, the thickness of the first region 10 can be, for example, but not limited to, 0.1mm, 1mm, 2mm, 3mm, 4mm, 5mm, etc., and the thickness of the second region 20 can be, for example, but not limited to, 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, etc.

[0066] In some embodiments, the first region 10 has at least two locations with different thicknesses for application to different parts of the body. By setting different thicknesses for the first region 10 according to the nerve distribution and skin thickness of different body parts, better ultrasound-focused therapy effects can be achieved, and treatment safety can be better ensured. For example, the thickness of the first region 10 is 0.5mm to 1mm for an ultrasound-focused therapy area applied to the side of the face. For example, the thickness of the first region 10 is 1mm to 2mm for an ultrasound-focused therapy area applied to the jawline. For example, the thickness of the first region 10 is 2mm to 3mm for an ultrasound-focused therapy area applied to the eye socket. For example, the thickness of the first region 10 is 1mm to 2mm for an ultrasound-focused therapy area applied to the chin.

[0067] Understandably, the ultrasound coupling patch 1 can also be customized to fit different ultrasound-focused treatment sites. By specifically designing the shape of the ultrasound coupling patch 1 to correspond to different ultrasound-focused treatment sites on the human body, directional shaping can be achieved, which can help adjust the depth of ultrasound treatment and indirectly adjust the position of the ultrasound focusing point, further improving the treatment effect.

[0068] See Figures 1-4 In some embodiments, the first region 10 includes a plurality of ultrasound coupling units 10, and the second region 20 includes a plurality of first enclosed ultrasound units 210; each ultrasound coupling unit 10 and each first enclosed ultrasound unit 210 is spaced apart along a first direction, or each ultrasound coupling unit 10 and each first enclosed ultrasound unit 210 is spaced apart along a second direction; the first direction refers to the height direction of the human body with reference to a standing person, and the second direction refers to the height direction perpendicular to the human body with reference to a standing person. In this way, the ultrasound focused treatment area and the non-treatment area can be clearly defined, allowing for accurate targeting of the treatment area during ultrasound probe strikes, while effectively protecting the non-treatment areas.

[0069] Furthermore, the ratio of the width of each ultrasound coupling part 10 to the width of each first closed ultrasound part 210 is 2:1 to 3:1. An appropriate width ratio can further enhance the precision of treatment and the sound transmission effect.

[0070] Please see Figure 1 Furthermore, the ultrasonic coupling film 1, which is applied to the treatment area of ​​the side face, is designed as follows: each ultrasonic coupling part 10 and each first closed ultrasonic part 210 are spaced apart along a first direction; the edge of the first region 10 passes through the edge of the mandible, the edge of the earlobe, the edge of the corner of the mouth, and the edge of the nose; the second region 20 also includes a second closed ultrasonic part 220, which is located at the edge of the first region 10 and close to the edge of the earlobe. This ensures effective ultrasonic focused treatment of the side face. Furthermore, the second closed ultrasonic part 220 is a fan-shaped area with a radius of 15mm~25mm and a central angle of 45°~55°, centered on the edge of the earlobe. Furthermore, the second region 20 also includes a third closed ultrasonic part 230, which is located at the edge of the first region 10 and close to the mandible; the ends of the two first closed ultrasonic parts 210 closest to the mandible are connected to the third closed ultrasonic part 230.

[0071] Please see Figure 2Furthermore, the ultrasonic coupling film 1, which is applied to the treatment area of ​​the mandible, is designed as follows: each ultrasonic coupling part 10 and each first closed ultrasonic part 210 are spaced apart along a second direction; the edge of the first region 10 passes through the edge of the mandible, the edge of the earlobe, below the edge of the earlobe, and below the midpoint of the chin; the second region 20 also includes a fourth closed ultrasonic part 240 and a fifth closed ultrasonic part 250; one end of the fourth closed ultrasonic part 240 is positioned close to the edge of the earlobe, and the other end is connected to the edge of the first region 10; the angle between the fourth closed ultrasonic part 240 and the first closed ultrasonic part 210 is 30°~40°; the fifth closed ultrasonic part 250 is located on the edge of the first region 10 between the edge of the earlobe and below the edge of the earlobe. This ensures effective ultrasonic focused treatment of the mandible.

[0072] Please see Figure 3 Furthermore, the ultrasound coupling patch 1, which is applied to the treatment area of ​​the orbit, is designed as follows: each ultrasound coupling part 10 and each first closed ultrasound part 210 are spaced apart along a second direction, and the edge of the first region 10 includes an arc line surrounding the eye, with the opening formed by the arc line facing the other eye. This ensures effective ultrasound-focused treatment of the orbit.

[0073] Please see Figure 4 Furthermore, the ultrasound coupling film 1, which is applied to the treatment area of ​​the chin, is designed as follows: each ultrasound coupling part 10 and each first closed ultrasound part 210 are spaced apart along a first direction, and the edge of the first region 10 is used to pass through the lower edge of the lip and the midpoint of the chin. In this way, effective ultrasound-focused treatment of the chin can be ensured.

[0074] Secondly, this application also provides a method for preparing the ultrasonic coupling film 1 as described in any of the embodiments of the first aspect above, comprising the following steps:

[0075] Provide a mold, which includes a first molding area and a second molding area;

[0076] A first base material is added to the first forming region, and a second base material is added to the second forming region; the first base material is used to prepare the material of the first region 10, and the second base material is used to prepare the material of the second region 20;

[0077] After static reaction, the film solidifies and forms, thus preparing the ultrasonic coupling film 1.

[0078] Understandably, the shape of the mold is adapted to the shape of the ultrasonic coupling film 1, and can be customized to match the design shape and thickness of the ultrasonic coupling film 1.

[0079] In some embodiments, the first base material is obtained by the following steps:

[0080] Carbomer, ethanol, water, and glycerol are mixed to form the first mixture;

[0081] Acrylamide and water are mixed to form a second mixture;

[0082] The first mixture and the second mixture are mixed in a preset ratio, and a catalyst is added to form the first base material.

[0083] Furthermore, the material of the second region 20 of the ultrasonic coupling film 1 also includes an ultrasonic coupling material, with the sealing ultrasonic material embedded within the ultrasonic coupling material; the second base material is obtained through the following steps:

[0084] The sealing ultrasonic material is mixed with the first base material to form the second base material.

[0085] Furthermore, the water in the first mixture is preferably deaerated water.

[0086] Furthermore, the water in the second mixture is preferably deaerated water.

[0087] Furthermore, in the first mixture, the mass ratio of carbomer, ethanol, water and glycerol is (8~12):(3~8):(40~60):(5~10).

[0088] Furthermore, in the second mixture, the mass ratio of acrylamide to water is (3~8):(15~25).

[0089] Furthermore, the mass ratio of the first mixture to the second mixture is (1~3):(3~4).

[0090] Furthermore, the mass ratio of the first mixture in the first base material to the sealing ultrasonic material is 1:(2~4).

[0091] Furthermore, the catalyst can be, but is not limited to, sodium persulfate and / or sodium bisulfite. Understandably, the type of catalyst is not limited to the above-mentioned catalysts; any strong oxidant capable of catalyzing the polymerization reaction of acrylamide to produce polyacrylamide can be used as a catalyst.

[0092] The ultrasonic coupling film 1 provided by the preparation method of this application has a uniform gel distribution, and the coupling channel is more uniform during use. There is no phenomenon of insufficient coating or lack of coating. The squeezing of the probe will not cause the gel to be reduced or missing due to sound transmission coupling. Moreover, the film can maintain a smooth flatness, and the probe can slide freely during use without affecting the ultrasonic transmission effect.

[0093] The ultrasonic coupling film 1 provided by the preparation method of this application is a special consumable for single use only. It can effectively form an isolation barrier between the skin surface and the probe, reducing cross-infection of skin bacteria and viruses between different patients. Moreover, the ultrasonic coupling film 1 can be directly removed after use without wiping, which is more hygienic and provides a better user experience, making it more suitable for the usage habits of modern cosmetic patients.

[0094] The ultrasonic coupling patch 1 provided by the preparation method of this application uses a high-sound-transmitting and high-transparency ultrasonic coupling material in the first region 10, which can effectively replace the traditional gel coupling agent. After solidification, it can form an ultrasonic coupling patch 1 with a specific shape and thickness. When used in conjunction with an ultrasonic focusing device in ultrasonic lifting treatment surgery, it can achieve more effective ultrasound transmission and enhance the treatment effect. Furthermore, the ultrasonic coupling patch 1, combined with the precise division of the treatment area and non-treatment area by the first region 10 and the second region 20, can ensure the safety of ultrasonic focusing treatment.
