Description

Technical Field

[0001] The present application relates to the technical field of ultrasonic introduction, and in particular to an ultrasonic introduction instrument. Background Art

[0002] The ultrasonic introduction device can use ultrasonic technology to introduce medicines or skin care products into the skin to enhance the skin's absorption rate of medicines and skin care products.

[0003] Among them, the ultrasonic introduction device can promote the skin's absorption of medicines and skin care products mainly because: the ultrasonic transducer of the ultrasonic introduction device generates ultrasonic waves that act on the skin surface, causing a cavitation effect in the medicines or skin care products applied on the skin surface, thereby disrupting the orderly molecular arrangement structure of lipids in the skin's stratum corneum, forming an infiltration channel, and changing the skin's permeability.

[0004] The ultrasonic transducer in the ultrasonic introduction instrument is arranged in an introduction cover (also called an introduction head, etc.) for contacting the skin in the ultrasonic introduction instrument, and transmits ultrasonic waves to the skin by contacting the introduction cover with the skin. However, although the skin area contacted by the introduction cover of the ultrasonic introduction instrument is relatively large, the introduction cover of the ultrasonic introduction instrument can only transmit ultrasonic waves to the part of the skin area contacted by the introduction cover, resulting in a very limited ultrasonic energy transmission area of ​​the ultrasonic introduction instrument. Summary of the invention

[0005] In view of this, the present application provides an ultrasonic introduction instrument to help increase the skin area where the introduction cover of the ultrasonic introduction instrument generates ultrasonic waves.

[0006] To achieve the above objectives, the present application provides an ultrasonic introduction device, comprising:

[0007] Ultrasonic wave introduction cover;

[0008] The ultrasonic introduction cover comprises: at least one ultrasonic transducer, and a flexible support layer carrying the at least one ultrasonic transducer and used for contacting with the skin of a living body;

[0009] Wherein, the ultrasonic transducer is made of flexible piezoelectric material.

[0010] Preferably, the ultrasonic transducer is in the form of a thin film.

[0011] Preferably, the ultrasonic wave introduction cover is an ultrasonic wave introduction mask that fits the human face.

[0012] Preferably, the flexible supporting layer is made of silica gel.

[0013] Preferably, the ultrasonic wave introduction cover comprises a plurality of ultrasonic transducers;

[0014] The plurality of ultrasonic transducers are distributed in different areas of the flexible supporting layer.

[0015] Preferably, the flexible support layer comprises: an inner surface arranged on the inner side of the ultrasonic wave introduction cover, and an outer surface arranged on the outer side of the ultrasonic wave introduction cover and used for contacting with the skin of a living body;

[0016] The ultrasonic transducer is adhered to the inner surface of the flexible supporting layer.

[0017] Preferably, the ultrasonic transducer is an ultrasonic transducer with multiple elements.

[0018] Preferably, it also includes: an ultrasonic control component;

[0019] The ultrasonic control component includes: a controller, an ultrasonic excitation circuit connected to the controller, and a human-computer interaction module connected to the controller and used to obtain the working state set by the user and output the working state of the ultrasonic introduction instrument;

[0020] Wherein, the ultrasonic excitation circuit is connected to the at least one ultrasonic transducer arranged on the ultrasonic wave introduction cover.

[0021] Preferably, the human-computer interaction module is used to obtain the import function set by the user;

[0022] The controller is used to determine the ultrasonic emission parameters according to the introduction efficacy set by the user, and control the ultrasonic excitation circuit to excite the ultrasonic transducer to output ultrasonic waves according to the ultrasonic emission parameters.

[0023] Preferably, when the ultrasonic wave introduction mask is an ultrasonic wave introduction mask that fits the human face, the ultrasonic wave introduction mask includes a plurality of introduction function areas that fit different areas of the human face;

[0024] The human-computer interaction module is used to obtain the import function set by the user for at least one of the import function areas;

[0026] From the above, it can be seen that in the embodiment of the present application, the ultrasonic transducer of the ultrasonic introduction cover of the ultrasonic introduction instrument is made of flexible piezoelectric material, so that the ultrasonic transducer is flexible, and the ultrasonic transducer is directly carried on the flexible support layer in contact with the biological body, which is beneficial to enhance the fit between the ultrasonic transducer and the flexible support layer carrying the ultrasonic transducer, and reduce the situation where the ultrasonic wave emitted by the ultrasonic transducer cannot be effectively transmitted to the skin due to the lack of fit between the ultrasonic transducer and the flexible support layer, thereby helping to increase the conduction area of ​​the ultrasonic introduction cover to transmit the ultrasonic wave to the skin.

[0033] An embodiment of the present application provides an ultrasonic introduction instrument, which is beneficial for increasing the effective area of ​​the ultrasonic introduction instrument, thereby increasing the conduction area of ​​ultrasound waves transmitted to the skin area through the introduction cover when the introduction cover area of ​​the ultrasonic introduction instrument is fixed.

[0034] The inventor of the present application has found through research that the effective area of ​​the ultrasonic introduction instrument on the skin is related to the skin area that can be covered by the ultrasonic transducer arranged on the ultrasonic introduction instrument. At the same time, the ultrasonic transducer is arranged on the inner side of the outer cover of the introduction cover of the ultrasonic introduction instrument, and the ultrasonic wave emitted by the ultrasonic transducer is transmitted to the skin through the outer cover. In order to ensure that the ultrasonic transducer can transmit the ultrasonic wave outward through the outer cover of the introduction cover, it is necessary to ensure that the ultrasonic transducer fits the outer cover. If there is a gap between the ultrasonic transducer and the outer cover, the ultrasonic wave emitted by the ultrasonic transducer cannot be transmitted outward through the outer cover. Considering that the ultrasonic transducers in the current ultrasonic introduction instruments are all made of hard piezoelectric materials, therefore, in order to ensure that the ultrasonic transducer fits the outer cover of the introduction cover, the ultrasonic transducer must be made into a point shape, which will inevitably lead to a smaller skin area covered by the ultrasonic transducer. In this case, even if the area of ​​the introduction cover of the ultrasonic introduction instrument is large, the effective area of ​​the ultrasonic transducer on the introduction cover is very small, which also limits the skin area that the introduction cover can act on.

[0035] At the same time, due to the structure of the ultrasonic transducer, it is difficult to ensure perfect fit between the ultrasonic transducer and the outer cover of the introduction cover in the ultrasonic introduction instrument, which can easily lead to the situation that the ultrasonic waves emitted by the ultrasonic transducer cannot be effectively transmitted to the skin, thereby affecting the effective area of ​​the introduction cover of the ultrasonic introduction instrument on the skin.

[0036] Combined with the above findings, the inventors of the present application have concluded through further research that if the ultrasonic transducer in the ultrasonic introduction instrument is made of flexible piezoelectric material, then the ultrasonic transducer will also be flexible, which is conducive to the fit of the ultrasonic transducer with the outer cover of the introduction cover, thereby reducing the situation where the ultrasonic wave cannot be effectively conducted due to the poor fit between the ultrasonic transducer and the outer cover. Moreover, under the premise that the ultrasonic transducer is flexible, since the ultrasonic transducer has better fit with the outer cover, even if the area of ​​the ultrasonic transducer is increased, the fit between the ultrasonic transducer and the outer cover can be guaranteed, so there is no need to design the ultrasonic transducer as a point shape, which is conducive to increasing the area of ​​the ultrasonic transducer. The increase in the area of ​​the ultrasonic transducer is conducive to increasing the area of ​​action of the ultrasonic transducer on the skin, and can also increase the coverage area of ​​the ultrasonic transducer on the introduction cover, thereby helping to reduce the blank area in the introduction cover that is not covered by the ultrasonic transducer, and then when the area of ​​the introduction cover is constant, it is conducive to increasing the skin area where the introduction cover produces ultrasonic effects on the skin.

[0037] Based on the above research findings, the ultrasonic introduction instrument of the embodiment of the present application at least includes an ultrasonic introduction cover. The ultrasonic introduction cover is a component of the ultrasonic introduction instrument used to contact the skin of a biological body such as a human body and introduce ultrasonic waves into the skin.

[0038] The ultrasonic wave introduction cover comprises: at least one ultrasonic transducer (also called ultrasonic transducer), and a flexible support layer carrying the at least one ultrasonic transducer and used for contacting with the skin of a living body.

[0039] In the embodiment of the present application, the ultrasonic transducer is an ultrasonic transducer made of flexible piezoelectric material.

[0040] The flexible support layer may be an outer cover of an ultrasonic introduction cover, and when the ultrasonic introduction device is used, the flexible support layer is used to contact the skin of a biological body such as a human body.

[0041] From the above, it can be seen that in the embodiment of the present application, the ultrasonic transducer of the ultrasonic introduction cover of the ultrasonic introduction instrument is made of flexible piezoelectric material, so that the ultrasonic transducer is flexible, and the ultrasonic transducer is directly carried on the flexible support layer in contact with the biological body, which is beneficial to enhance the fit between the ultrasonic transducer and the flexible support layer carrying the ultrasonic transducer, and reduce the situation where the ultrasonic wave emitted by the ultrasonic transducer cannot be effectively transmitted to the skin due to the lack of fit between the ultrasonic transducer and the flexible support layer, thereby helping to increase the conduction area of ​​the ultrasonic introduction cover to transmit the ultrasonic wave to the skin.

[0042] At the same time, the outer cover of the ultrasound introduction cover of the ultrasound introduction instrument of the present application is a flexible supporting layer, which can not only facilitate the fitting of the ultrasound transducer and the outer cover, but also improve the comfort of skin contact.

[0043] For ease of understanding, an introduction is given below with reference to the accompanying drawings.

[0044] For example, see Figure 1 , which shows a cross-sectional structural schematic diagram of the ultrasonic introduction cover of the ultrasonic introduction instrument of the present application.

[0045] Depend on Figure 1 It can be seen that the ultrasonic wave introduction cover includes at least one ultrasonic transducer 101 and a flexible supporting layer 102 that carries the at least one ultrasonic transducer 101 .

[0046] The flexible support layer 102 is located at the outermost layer of the ultrasonic wave introduction cover, and is used not only as the outer cover of the ultrasonic wave introduction cover, but also for carrying the ultrasonic transducer in the ultrasonic wave introduction cover.

[0047] Among them, the present application adopts a flexible support layer to carry the ultrasonic transducer, which is conducive to the stable fitting of the flexible support layer and the ultrasonic transducer and reduces the gap between the two, so that the ultrasonic waves emitted by the ultrasonic transducer can be stably transmitted to the skin contact layer through the flexible support layer; at the same time, it can also improve the skin comfort when the ultrasonic wave introduction cover contacts the skin.

[0048] It is understandable that the specific material of the flexible support layer can be set as needed, as long as it can ensure that it is suitable for contacting the skin and is conducive to stable fitting with the ultrasonic transducer.

[0049] Optionally, in order to ensure the comfort of the ultrasound introduction cover in contact with the skin, the flexible support layer can be made of a skin-friendly material. Further, considering the skin-friendly properties of silicone material, in the embodiment of the present application, the flexible support layer can be made of silicone material.

[0050] In the embodiment of the present application, the ultrasonic transducer 101 is located inside the ultrasonic introduction cover, for example, from the outermost layer to the inner layer of the ultrasonic introduction cover, that is, Figure 1 From bottom to top, there are the flexible supporting layer 102 and the ultrasonic transducer 101 disposed in the flexible supporting layer.

[0051] The ultrasonic transducer 101 is made of flexible piezoelectric material, so that the ultrasonic transducer has the characteristics of being soft and easy to adhere to other dielectric layers.

[0052] In the embodiment of the present application, a flexible ultrasonic transducer is disposed on the flexible supporting layer. Since both the flexible supporting layer and the ultrasonic transducer are flexible, it is beneficial for the ultrasonic transducer to fit the flexible supporting layer, so that the ultrasonic transducer is fixed on the ultrasonic wave introduction mask.

[0053] In the embodiments of the present application, the ultrasonic transducer made of flexible piezoelectric material can have various specific forms, for example, the ultrasonic transducer can be in a point shape.

[0054] Optionally, in order to increase the effective area of ​​the ultrasonic transducer, the ultrasonic transducer may be in the form of a thin film sheet. For example, the ultrasonic transducer is made of a flexible thin film piezoelectric material such as polyvinylidene fluoride (PVDF). Since the thin film sheet ultrasonic transducer made of flexible piezoelectric material can generate ultrasonic waves within the entire thin sheet coverage range after being excited by voltage, it is beneficial to increase the coverage area of ​​the ultrasonic wave.

[0055] The specific shape of the thin film sheet-shaped ultrasonic transducer can be various, for example, it can be a circular thin film sheet, a square thin film sheet, a trapezoidal thin film sheet, etc.

[0056] It is understandable that, compared with a point-shaped ultrasonic transducer, a thin-film sheet-shaped ultrasonic transducer can cover a larger skin area, thereby increasing the skin area where the ultrasonic wave acts. Moreover, since the area of ​​the thin-film sheet-shaped ultrasonic transducer is relatively large, it is beneficial to increase the area of ​​the flexible support layer covered by the ultrasonic transducer, thereby facilitating that the flexible support layer is completely covered by the ultrasonic transducer, so that the outer cover area of ​​the ultrasonic wave introduction cover is consistent with the ultrasonic wave action area, greatly increasing the action area of ​​the ultrasonic wave introduction cover to introduce the ultrasonic wave into the skin.

[0057] At the same time, since the area of ​​the thin film sheet-like ultrasonic transducer is relatively large, when the ultrasonic transducer is set on the flexible supporting layer, the contact area between the ultrasonic transducer and the flexible supporting layer is also large, which is conducive to the stable setting of the ultrasonic transducer on the flexible supporting layer.

[0058] There are many specific ways to set the ultrasonic transducer on the flexible support layer. For example, in one implementation, the ultrasonic transducer can be pasted on the surface of the flexible support layer. Since the flexible support layer includes two surfaces, an inner surface and an outer surface, the outer surface of the flexible support layer is on the outside of the ultrasonic wave introduction cover, and is used as the surface of the ultrasonic wave introduction cover contacting the skin; while the inner surface of the flexible support layer is on the inside of the ultrasonic wave introduction cover, therefore, the ultrasonic transducer can be pasted on the inner surface of the flexible support layer to maintain the flatness and comfort of the outer surface of the flexible support layer. Figure 1 As shown, it shows a schematic diagram of a thin film sheet ultrasonic transducer made of flexible piezoelectric material pasted on the inner surface of the flexible supporting layer.

[0059] Of course, sticking the ultrasonic transducer on the flexible supporting layer is only one way to set the ultrasonic transducer on the inner surface of the flexible supporting layer. In practical applications, the ultrasonic transducer can also be set on the inner surface of the flexible supporting layer in other ways, and the present application does not limit this.

[0060] For example, in another implementation, the present application may also embed the ultrasonic transducer into the flexible supporting layer, so that the ultrasonic transducer is surrounded by the flexible supporting layer, thereby making the ultrasonic transducer stably fixed in the flexible supporting layer.

[0061] Of course, in the application, the flexible support layer may also support the ultrasonic transducer in other ways, and the present application does not impose any limitation on this.

[0062] In the embodiment of the present application, the ultrasonic transducer may have a single-element or multi-element ultrasonic transducer. The higher the number of elements of the ultrasonic transducer, the greater the number of ultrasonic beams emitted by the ultrasonic transducer. Optionally, in order to further improve the effect of the ultrasonic introduction instrument, the ultrasonic transducer in the embodiment of the present application may be a multi-element ultrasonic transducer.

[0063] It is understandable that, since the area on which the ultrasound waves emitted by a single ultrasonic transducer can act is very limited, although the ultrasonic transducer made of flexible piezoelectric material can be designed to have a larger area, it is still possible to not be able to cover the entire flexible support layer with the area of ​​the single ultrasonic transducer in consideration of issues such as design complexity. Optionally, in order to further increase the skin area that the ultrasonic introduction instrument can act on, in an embodiment of the present application, a plurality of flexible ultrasonic transducers can be provided in the ultrasonic introduction cover of the ultrasonic introduction instrument.

[0064] Among them, the multiple ultrasonic transducers of the ultrasonic introduction cover are distributed in different areas of the flexible support layer. For example, the multiple ultrasonic transducers can be evenly distributed in different areas of the inner surface of the flexible support layer. For another example, different introduction functional areas of the ultrasonic introduction cover can be set, such as a strong introduction functional area and a weak introduction functional area, and accordingly, different numbers of ultrasonic transducers can be set in the areas of the flexible support layer for different introduction functional areas. For example, the number of ultrasonic transducers set in the corresponding area of ​​the flexible support layer corresponding to the strong introduction functional area is relatively large, while a relatively small number of ultrasonic transducers are set in the area of ​​the flexible support layer corresponding to the weak introduction functional area.

[0065] It can be understood that when a plurality of ultrasonic transducers are distributed on the flexible support layer of the ultrasonic introduction cover, the plurality of ultrasonic transducers can more comprehensively cover various areas of the flexible support layer, so that the ultrasonic wave emitted by each ultrasonic transducer can almost diffuse to the entire flexible support layer, and the entire outer layer of the ultrasonic introduction cover can transmit the ultrasonic wave to the skin, so that the ultrasonic action area of ​​the ultrasonic introduction instrument can almost cover the entire skin area contacted by the ultrasonic introduction cover.

[0066] Accordingly, when the user uses the ultrasonic introduction cover of the ultrasonic introduction instrument to contact the skin, since the action area of ​​the ultrasonic introduction instrument of the present application on the skin is converted from the existing point area under the ultrasonic transducer to the entire sheet area under the ultrasonic transducer, it is even possible to expand the action area to the entire skin area contacted by the ultrasonic introduction cover, thereby reducing the number of times the user frequently moves the ultrasonic introduction cover to change the action area.

[0067] It is understandable that, due to the different application scenarios of the ultrasonic introduction device, the ultrasonic introduction cover may have a variety of external shapes.

[0068] For example, when the ultrasonic introduction device is used to introduce medicines or skin care products into a local area of ​​a biological body, the ultrasonic introduction cover of the ultrasonic introduction device can be a circular introduction cover with a certain area, and accordingly, the flexible support layer in the ultrasonic introduction cover is in the shape of the circle to match the shape and size of the circular introduction cover. For example, the ultrasonic introduction cover can be the same shape as the introduction head used to contact the skin in a common handheld ultrasonic introduction device.

[0069] For another example, the ultrasonic wave introduction cover may be an introduction cover with a square contact plane, and the flexible support layer may be a square. For example, the ultrasonic wave introduction cover may be a rectangular sheet film.

[0070] Taking into account the fact that there are many application scenarios for using ultrasonic introduction devices for facial skin care or skin disease treatment, and in order to facilitate users to use the ultrasonic introduction device on the face and increase the effective area of ​​the ultrasonic introduction device on the human face, in an embodiment of the present application, the ultrasonic introduction cover can be an ultrasonic introduction mask that fits the human face.

[0071] For example, see Figure 2 , which shows a schematic diagram of the structure of the ultrasonic introduction cover of the present application. Figure 2 In the invention, the ultrasonic wave introduction cover is an ultrasonic wave introduction face mask.

[0072] like Figure 2 As shown, the ultrasonic wave introduction cover 201 is a mask that can cover the human face, and the outer edge contour matches the human face contour, that is, the ultrasonic wave introduction cover 201 is an ultrasonic wave introduction mask.

[0073] Correspondingly, the flexible supporting layer in the ultrasonic wave introduction mask is a mask-shaped thin layer whose outer edge contour matches the contour of the human face.

[0074] Among them, the flexible support layer of the ultrasonic wave introduction mask can carry at least one ultrasonic transducer made of flexible piezoelectric material. Optionally, in order to improve the ultrasonic wave introduction effect, the ultrasonic wave introduction mask can include multiple ultrasonic transducers made of flexible piezoelectric material, and the multiple ultrasonic transducers can be distributed in different areas of the flexible support layer. In this way, when the ultrasonic wave introduction mask is covered on the face of a person, the multiple ultrasonic transducers can be respectively located in different parts of the face, so that ultrasonic waves can be effectively emitted to different parts of the face.

[0075] Among them, the specific distribution of the multiple ultrasonic transducers in the flexible supporting layer can be combined with the matching relationship between the flexible supporting layer and the facial part of the human face, and according to the skin care needs of different facial parts, ultrasonic transducers are distributed in the flexible supporting layer corresponding to various areas of different facial parts.

[0076] For example, in Figure 2 FIG. 1 shows a schematic diagram of the distribution positions of multiple ultrasonic transducers on the ultrasonic wave introduction mask. Figure 2 It can be seen that a plurality of ultrasonic transducers 202 are distributed on the ultrasonic introduction mask 201, such as Figure 2 As shown in the black flakes. Figure 2 In the example, the ultrasonic transducer is in the form of a thin film sheet.

[0077] At the same time, combined Figure 3 Description, in Figure 3 It shows a schematic diagram of the relative positional relationship between the multiple ultrasonic transducers 202 arranged on the ultrasonic introduction mask 201 and different parts of the face after the ultrasonic introduction mask is covered on the face of the person.

[0078] Combination Figure 3 It can be seen that when the ultrasonic introduction mask covers the human face, the ultrasonic transducers can be located in the upper layer of different facial areas of the human face respectively, so that the ultrasonic waves emitted by the multiple ultrasonic transducers are transmitted to the human facial skin through the flexible supporting layer. Since the thin film sheet-shaped ultrasonic transducer almost covers the entire ultrasonic introduction mask, the ultrasonic energy can be diffused to the entire face of the human face. In this way, the ultrasonic introduction instrument can produce ultrasonic effects on the entire facial skin of the human face, thereby promoting the rapid introduction of medicines or skin care products applied to the entire face of the human face, and improving the transdermal penetration rate of medicines and skin care products into the entire facial skin.

[0079] Moreover, when the user uses the ultrasonic introduction device of the present application to introduce medicines or skin care products, since the ultrasonic introduction mask of the ultrasonic introduction device can cover the entire facial skin of the human face, and the ultrasonic wave can be diffused to almost the entire facial skin of the human face through the ultrasonic introduction mask, the user can complete the introduction of medicines and skin care products to the entire face without manually moving the ultrasonic introduction device, which is more convenient to use.

[0080] It is understandable that the specific forms and shapes of the multiple ultrasonic transducers arranged on the flexible support layer may not be completely the same. For example, taking the ultrasonic transducer as a thin film sheet ultrasonic transducer made of a flexible piezoelectric material as an example, the shapes of the ultrasonic transducers distributed in different areas of the flexible support layer may also be different. For example, the ultrasonic transducers in the areas corresponding to different parts of the face of the human body may be arranged in the flexible support layer according to the shape characteristics of different parts of the face. Figure 3 The shape of the ultrasonic transducer in the area of ​​the flexible supporting layer corresponding to the forehead of the human face is a trapezoidal sheet, while the other parts can be elliptical or arc-shaped, etc.

[0081] Optionally, considering that the skin care or drug introduction effects to be achieved in different areas of the human face may be different, for example, the forehead of the human face may be more concerned with wrinkle removal, while the cheeks of the human face may be more concerned with freckle removal and whitening, therefore, the ultrasonic introduction mask may include multiple introduction functional areas that fit different areas of the human face, and accordingly, the flexible supporting layer will also be divided into area areas corresponding to the multiple introduction functional areas.

[0082] Among them, different introduction functional areas of the ultrasonic introduction mask can correspond to different facial parts of the human face. That is to say, when the ultrasonic introduction mask is applied to the human face, the different introduction functional areas of the ultrasonic introduction mask are located at different parts of the face. In combination with the facial parts of the human face corresponding to the different introduction functional areas of the ultrasonic introduction mask, the number and distribution of ultrasonic transducers in each introduction functional area can be set as needed. At the same time, the specific form of the ultrasonic transducer in each introduction functional area can also be different.

[0083] like Figure 4 , which shows a schematic diagram of the relative position relationship between the various introduction functional areas of the ultrasonic introduction mask and various parts of the human face.

[0084] Depend on Figure 4 As shown, the ultrasonic introduction mask is divided into multiple introduction functional areas. Figure 4 The ultrasonic wave introduction mask is divided into a plurality of introduction function areas by dotted lines, namely, cheek introduction function area 401, eye introduction function area 402, and forehead introduction function area 403. Figure 4 It can be seen that each introduction functional area can be equipped with the same or different numbers of ultrasonic transducers according to different needs for medicines and skin care products. Moreover, the ultrasonic introduction instrument can control the ultrasonic transducers in each introduction functional area to work separately, and control different introduction functional areas to have different ultrasonic intensities and frequencies, etc., so as to achieve the desired effects of different introduction functional areas, which will be described in detail later.

[0085] It is understandable that, in order to improve the comfort of use, two eye holes, one nose hole and one mouth hole can be provided on the ultrasonic wave introduction mask, and the eye holes, nose holes and mouth holes can respectively expose the eyes, nose and mouth of the face. Figure 2 The eye through hole 203, the nose through hole 204 and the mouth through hole 205 are shown in the figure to avoid the mask covering these parts and causing discomfort to the user.

[0086] Correspondingly, when the ultrasonic wave introduction mask is covered on the human face, the eye holes of the ultrasonic wave introduction mask match the human eye parts, so that the human eyes can open and close normally through the eye holes without affecting the user's line of sight; at the same time, the nose holes of the ultrasonic wave introduction mask will match the nose part of the human face, and the mouth holes on the ultrasonic wave introduction mask will match the mouth of the human face, so that the nose and mouth of the human face will not be blocked by the ultrasonic wave introduction mask, and the user's normal breathing will not be affected.

[0087] It is understandable that when the user lies flat or reclining, the ultrasonic wave introduction mask can be applied to the face of the user, so as to use the ultrasonic wave introduction mask to achieve rapid and efficient introduction of ultrasonic skin care products or medicines. In order to ensure that the ultrasonic wave introduction mask can be stably applied to the face and will not slip due to the movement of the user, the ultrasonic wave introduction mask can also be provided with a wearing component for wearing the ultrasonic wave introduction mask on the face of the user, such as the ultrasonic wave introduction mask can also be connected with a wearing rope or a wearing buckle, or a headgear or earmuffs that can wear the ultrasonic wave introduction mask on the head or ears of the person.

[0088] It can be understood that in any of the above embodiments of the ultrasonic introduction device of the present application, in order to be able to control the ultrasonic transducer in the ultrasonic introduction mask and stimulate the ultrasonic transducer to generate ultrasonic waves, the ultrasonic introduction device of the embodiment of the present application may also include: an ultrasonic control component.

[0089] The ultrasonic control component includes: a controller and an ultrasonic excitation circuit connected to the controller.

[0090] The ultrasonic excitation circuit is connected to at least one ultrasonic transducer arranged on the ultrasonic wave introduction cover, and is used to excite the ultrasonic transducer to emit ultrasonic waves under the control of the controller.

[0091] The ultrasonic excitation circuit is connected to the ultrasonic transducer on the ultrasonic introduction mask through a physical line. In the case where the ultrasonic introduction mask has a wireless conversion module, the ultrasonic excitation circuit can also send an excitation signal through the wireless conversion module in the ultrasonic introduction mask, and convert the corresponding excitation signal to each ultrasonic transducer connected to the wireless conversion module through the wireless conversion module.

[0092] Accordingly, the ultrasonic control component can be connected to the ultrasonic introduction mask via a connecting line, and the connecting line can include a data communication line connecting the ultrasonic excitation circuit in the ultrasonic control component and the ultrasonic transducer in the ultrasonic introduction mask. Of course, the ultrasonic control component and the ultrasonic introduction mask can also be two physically independent components, but the ultrasonic control component can control the ultrasonic transducer in the ultrasonic introduction mask based on wireless communication.

[0093] In the embodiment of the present application, there may be multiple specific types of the controller. For example, the controller may be a complex programmable logic device (CPLD) as the controller.

[0094] The controller can control the working parameters of the ultrasonic introduction instrument. For example, the controller can also be connected to the ultrasonic transducer on the ultrasonic introduction mask to control the ultrasonic transducer to work or stop working, and can also control the working frequency, repetition frequency, occupancy rate and intensity of the ultrasonic transducer.

[0095] It is understandable that since the amplitude of the coded waveform output by the controller such as CPLD is very small and insufficient to directly drive the ultrasonic transducer, an ultrasonic excitation circuit is required to excite the ultrasonic transducer to emit ultrasonic waves.

[0096] It is understandable that there may be many specific components and structures of the ultrasonic excitation circuit, as long as it can excite the ultrasonic transducer to generate ultrasonic waves. The present application does not impose any restrictions on the specific composition of the ultrasonic excitation circuit.

[0097] Optionally, in order to reduce the design complexity of the ultrasonic excitation circuit and improve the stability and flexibility of the ultrasonic excitation circuit, the present application may adopt a digital design scheme to construct the ultrasonic excitation circuit. For example, the ultrasonic excitation circuit may be composed of an ultrasonic transducer driver chip and an enhanced field effect transistor.

[0098] It is understandable that in order to facilitate the user to view the working status of the ultrasonic introduction instrument and control the working status and working parameters of the ultrasonic introduction instrument, the ultrasonic control component may also include: a human-computer interaction module connected to the controller, and the human-computer interaction module is an interface for the user to interact with the ultrasonic introduction instrument.

[0099] The human-computer interaction module is used to obtain the working state set by the user and output the working state of the ultrasonic introduction instrument. For example, the human-computer interaction module can output the current working state of the ultrasonic introduction instrument, such as the power-on state, power-off state, working mode, ultrasonic related parameters and other working state related information in the controller of the controller.

[0100] The human-machine interaction module may include input control devices such as a touch screen, physical buttons, and a control panel to obtain the working status set by the user. For example, the display interface of the human-machine interaction module may use a color screen control panel to control the touch screen, and its working voltage may be 5V and the current may be 100mA. The touch screen may display the current working status of the ultrasound introduction instrument.

[0101] The working state set by the user through the human-computer interaction module may include: turning on the ultrasonic introduction instrument, turning off the ultrasonic introduction instrument, setting working parameters of the ultrasonic introduction instrument, etc.

[0102] It is understandable that human skin is divided into the epidermis and dermis, and the epidermis includes five layers: stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum and stratum basale. The maximum effect of different skin care products or medicines is closely related to the ability of specific layers of skin to effectively absorb their active ingredients. For example, skin care products with whitening ingredients need to penetrate into the deepest basal layer of the epidermis, while skin care products with anti-wrinkle ingredients need to penetrate into the deeper dermis to maximize their effects.

[0103] However, the inventors have found through analysis of existing ultrasonic introduction devices that the current ultrasonic introduction devices can only generate specific ultrasonic waves, which is not conducive to introducing products with different functions into different skin layers.

[0104] In order to enable the precise introduction of skin care products or medicines into the corresponding skin layers and further improve the skin's absorption efficiency of skin care products or medicines, in an embodiment of the present application, the human-computer interaction module obtains the working status set by the user and may also include: obtaining the introduction efficacy set by the user.

[0105] For example, in one implementation, the human-computer interaction module can display the introduction effects that can be selected by the user in the display area of ​​the human-computer interaction module under the control of the controller. For example, the introduction effects may include: whitening, anti-wrinkle, moisturizing, etc., or introduction into a certain skin layer, etc. The user can select the required introduction effect according to the needs.

[0106] For example, in yet another implementation, the user may directly input the desired import function in an input area such as a touch screen of the human-computer interaction module.

[0107] Correspondingly, the controller is also used to determine the ultrasonic emission parameters according to the introduction effect set by the user, and control the ultrasonic excitation circuit to excite the ultrasonic transducer to emit ultrasonic waves according to the determined ultrasonic emission parameters.

[0108] The ultrasonic emission parameters may include one or more of the following parameters: ultrasonic emission frequency, ultrasonic excitation intensity, ultrasonic pulse length, pulse occupancy ratio, pulse repetition frequency, ultrasonic continuous action time and action mode.

[0109] It is understandable that, since different introduction effects require that the product to be introduced (skin care products or medicines) be introduced into different skin layers, it is necessary to control the emission parameters of the ultrasound wave so as to achieve the cavitation effect in different skin layers through the ultrasound wave, thereby introducing the product into the corresponding skin layer. It can be seen that different introduction effects actually correspond to different skin layers, and different skin layers correspond to different ultrasound emission parameters. Therefore, the ultrasound emission parameters required to produce the cavitation effect in a specific skin layer can be obtained through data or experimental analysis.

[0110] Among them, the main mechanism of ultrasonic ultrasound introduction is cavitation effect. For a certain introduction effect, since the skin layer corresponding to the introduction effect is known, the ultrasonic parameters required to achieve the cavitation effect of ultrasound in the skin layer can be determined through mathematical analysis. For easy understanding, the principle is briefly explained:

[0111] There are tiny cavitation nuclei (also called micro-gas-core cavitation bubbles) in the liquid of skin care products or medicines. After being subjected to the alternating stretching and squeezing force of ultrasound, these cavitation nuclei will continue to grow and quickly collapse and close, thereby producing a cavitation effect. Under the action of ultrasound, cavitation effects are not only induced in the skin care products or medicines on the surface of the skin, but also in the intercellular matrix under the stratum corneum or in the tissue cells. The strength of the cavitation effect is closely related to the ultrasonic emission parameters in the ultrasonic introduction instrument, and the strength of the cavitation effect determines the skin layer that the skin care products or medicines to be introduced can reach. For example, the relevant parameters of ultrasound and the motion equation of cavitation nuclei can be found in Formula 1:

[0112]

[0113] For the convenience of description, the cavitation core bubble is called a microbubble, where R is the instantaneous radius of the microbubble vibration, ρ is the density of the fluid surrounding the microbubble, and p g0 is the equilibrium pressure inside the microbubble, R 0 is the static equilibrium radius of the microbubble, ω is the angular frequency of the incident ultrasound, and p v is the vapor pressure inside the microbubble, p 0 is the hydrostatic pressure of the liquid around the microbubble, σ is the surface tension of the microbubble, Γ is the polytropic gas index, p ac (t) is the incident sound field of the ultrasonic wave, δ t is the total damping coefficient.

[0114] It can be understood that by solving formula 1, the movement process curve of the microbubbles can be obtained. Therefore, combining the movement process curve of the microbubbles and the skin layer into which the product is to be introduced, the ultrasonic emission parameters required for introduction into the skin layer can be analyzed.

[0115] Of course, in practical applications, mathematical calculations and experimental analysis results can also be combined to finally synthesize the ultrasonic emission parameters corresponding to different skin layers. For example, an electron microscope is used to observe and calculate the micropores on the surface of skin tissue after ultrasound action, and the density of micropores and the maximum pore radius are used to reflect the skin permeability. Then, by analyzing the measurement results of the number and maximum radius of micropores on the skin surface under ultrasound conditions of different frequencies and intensities, a quantitative analysis of the various ultrasonic parameters and the penetration-enhancing effect is performed.

[0116] On the basis of analyzing the ultrasonic emission parameters required for different introduction effects, the present application can preset the ultrasonic emission parameters required for achieving different introduction effects, such as storing the ultrasonic emission parameters corresponding to different introduction effects in the controller or a memory connected to the controller. Accordingly, according to the correspondence between the introduction effect and the ultrasonic emission parameters, the ultrasonic emission parameters required for the introduction effect set by the user can be determined.

[0117] It can be understood that since the controller in the ultrasonic introduction instrument of the embodiment of the present application can determine the ultrasonic parameters required to achieve the introduction effect according to different introduction effects, it can reasonably control the ultrasonic excitation circuit to excite the ultrasonic transducer to emit ultrasonic waves, so that the ultrasonic waves output by the ultrasonic transducer can produce a cavitation effect in the skin layer corresponding to the introduction effect, so that the skin care products and medicines can achieve the introduction effect, thereby realizing the precise introduction of skin care products and medicines into the corresponding skin layers, and maximizing the efficacy of skin care products and medicines.

[0118] Optionally, in order to further improve the accurate introduction of skin care products or medicines, when the ultrasonic introduction mask includes multiple introduction functional areas, the user can also set corresponding introduction functions for one or more of the multiple introduction functional areas.

[0119] Correspondingly, the human-computer interaction module is used to obtain the import function set by the user for at least one import function area. The controller can determine the ultrasonic emission parameters corresponding to each import function area set by the user according to the import function set for the import function area; and control the ultrasonic excitation circuit to excite the ultrasonic transducer in the import function area to output ultrasonic waves according to the determined ultrasonic emission parameters.

[0120] It is understandable that in order to ensure the normal power supply of the ultrasonic introduction instrument and provide power to the controller and the human interaction module in the ultrasonic control component, the ultrasonic control component may also include a power supply circuit. For example, the power supply circuit may use a switching regulator to provide the required voltage for each component.

[0121] For ease of understanding, the ultrasonic introduction mask is an ultrasonic introduction mask as an example for explanation, and the ultrasonic introduction mask is connected to the ultrasonic control component through a connecting line as an example. Figure 5 , which shows a schematic diagram of the composition structure of the ultrasonic introduction device of the present application.

[0122] Depend on Figure 5 It can be seen that the ultrasonic introduction instrument includes: an ultrasonic introduction mask 51 and an ultrasonic control component 52 connected to the ultrasonic introduction mask via a connecting line.

[0123] The ultrasonic wave introduction mask 51 may include at least one ultrasonic transducer 511 made of a flexible piezoelectric material and a flexible support layer (due to the flexible support layer) carrying the at least one ultrasonic transducer. Figure 5 It is a plan view. Figure 5 The flexible support layer is not shown in the figure). The details of the ultrasonic introduction mask can be found in the above related introduction, which will not be repeated here.

[0124] The ultrasonic control component 52 includes: a controller 521 , an ultrasonic excitation circuit 522 , a human-computer interaction module 523 and a power supply circuit 524 .

[0125] The ultrasonic excitation circuit 522 , the human-machine interaction module 523 and the power supply circuit 524 are all connected to the controller 521 . The ultrasonic excitation circuit 522 and the human-machine interaction module 523 are also connected to the power supply circuit 524 .

[0126] The ultrasonic excitation circuit is connected to each ultrasonic transducer in the ultrasonic wave introduction mask through a communication line.

[0127] In the embodiment of the present application, the human-computer interaction module can be a touch screen, and the controller can control the touch screen to display the working status of the ultrasonic introduction instrument and the ultrasonic parameters of the ultrasonic introduction mask, such as ultrasonic intensity, frequency, etc. At the same time, the human-computer interaction module can also receive the user's control of the working frequency, working time, and action area of ​​the ultrasonic introduction mask.

[0128] The user can input control parameters for the entire ultrasonic wave introduction mask through the human-computer interaction module, such as the working parameters for controlling the ultrasonic wave introduction mask to the entire face of the human being.

[0129] The user can also use the human-computer interaction module to individually control the ultrasonic introduction mask to introduce ultrasonic waves with different ultrasonic emission parameters into different areas of the face, so as to achieve different introduction effects for different areas of the face. For example, the ultrasonic introduction mask can include multiple introduction function areas that fit different areas of the human face, for example, the introduction function area can be the eye introduction function area, cheek introduction function area, etc. mentioned above. The user can select one or more introduction function areas in the human-computer interaction module to be in working state. The introduction function area in working state will emit ultrasonic waves to the facial skin corresponding to the introduction function area; while the introduction function area that is not in working state will not emit ultrasonic waves.

[0130] At the same time, the user can also specifically set the import effects required for different import function areas, such as selecting and setting the import effects required for one or more import function areas. Among them, the import effect can be the effect achieved by importing skin care products or medicines, such as the import effect can be a whitening effect or a wrinkle removal effect. The import effect can also be the skin layer to be imported, such as the import effect can be the dermis layer, the basal layer of the epidermis layer, etc.

[0131] Accordingly, the human-computer interaction module can obtain the import functions set by the user for at least one import function area. The controller is used to determine the ultrasonic emission parameters corresponding to each import function area set by the user according to the import function set for the import function area; and control the ultrasonic excitation circuit to excite the ultrasonic transducer in the import function area to output ultrasonic waves according to the determined ultrasonic emission parameters.

[0132] For example, suppose the user needs to use an ultrasonic introduction mask to introduce a product with wrinkle removal and whitening effects to the face, but for the forehead, the user hopes to achieve the effect of wrinkle removal; and for the cheek, the user hopes to achieve the effect of whitening. In this case, the user can set the introduction effect of the forehead introduction function area to wrinkle removal on the human-computer interaction module, and set the introduction effect of the cheek introduction function area to whitening. The controller can determine the ultrasonic emission parameters corresponding to wrinkle removal and the ultrasonic emission parameters corresponding to whitening. At the same time, the controller can control the ultrasonic recording circuit to excite the ultrasonic transducer in the forehead introduction function area to emit ultrasonic waves according to the ultrasonic emission parameters corresponding to wrinkle removal; and control the ultrasonic excitation circuit to record the ultrasonic transducer in the forehead introduction function area to emit ultrasonic waves according to the ultrasonic emission parameters corresponding to whitening.

[0133] It can be seen that the ultrasonic introduction instrument of the present application can control the introduction function of different introduction functional areas of the ultrasonic introduction mask, so as to realize the precise introduction of different effects to different areas of the face using the ultrasonic introduction mask, and realize the precise introduction of skin care products or medicines, etc.
