Description

Technical Field

[0001] The present application relates to the field of cosmetic technology, and in particular to a non-invasive shock wave transdermal injection device for cosmetic use. Background Art

[0002] Currently, there are two types of needle-free injection devices on the market:

[0003] One method is to use high-pressure jets to physically perforate the skin with liquid medicine, which will leave penetrating blood holes on the skin, causing great trauma to the skin and cannot be used in the beauty industry.

[0004] Another method uses medium- and low-pressure atomization. While non-invasive, it has a low airflow velocity. However, its ability to penetrate the skin, particularly the stratum corneum, is weak. Even after penetration, the depth of the drug solution cannot be controlled, and the drug cannot accurately reach the collagen cells approximately 1 mm below the epidermis. This results in waste and fails to achieve the desired cosmetic effect, resulting in poor market feedback. Furthermore, since further pressurization of medium- and low-pressure atomization technology is no longer able to increase the jet velocity, it has reached a technical bottleneck. Summary of the Invention

[0005] The purpose of this application is to provide a shock wave injector that improves the penetration effect of liquid medicine under low pressure conditions and is non-invasive to the skin.

[0006] In order to solve the above technical problems, an embodiment of the present application provides a cosmetic shock wave transdermal injection device, including a shell, a charging mechanism, a pilot solenoid valve, a shock wave generating element and a shock wave balancing tube; the charging mechanism, the pilot solenoid valve, the shock wave generating element and the shock wave balancing tube are all installed on the shell; one end of the pilot solenoid valve is connected to the air source, and the other end is connected to the shock wave generating element; the shock wave generating element is provided with a front end of a shock wave generating cavity that gradually expands along the direction of the airflow; the shock wave balancing tube is connected to the shock wave generating element, and the shock wave balancing tube is provided with a rear end of a shock wave generating cavity that gradually contracts along the direction of the airflow and an injection cavity connected to the rear end of the shock wave generating cavity, and the inner diameter of the injection cavity gradually expands along the direction of the airflow; the pilot solenoid valve is used to speed up the gas and inject it through the front end of the shock wave generating cavity, the rear end of the shock generating cavity and the injection cavity in sequence; the shock balancing tube is connected to the charging mechanism.

[0007] In the above technical solution, further, the shock wave generating component is provided with a piston sealing chamber, a transition chamber and a front end of the shock wave generating chamber which are connected in sequence; the piston sealing chamber is used for adapting and connecting with the pilot solenoid valve.

[0008] In the above technical solution, further, the piston sealing cavity is provided with a conical surface that gradually contracts along the airflow direction.

[0009] In the above technical solution, further, an outer wall of one end of the shock wave generating component is formed with an external thread, and the pilot solenoid valve is provided with an internal thread interface adapted to the external thread.

[0010] In the above technical solution, further, the shock wave balancing tube is connected to the shock wave generating component in a detachable form, the shock wave generating component is provided with a stepped plug-in position, one end of the shock wave balancing tube is provided with a step structure, and the step structure is installed on the plug-in position.

[0011] In the above technical solution, further, the injection cavity is a conical surface, and the angle between the axis of the conical surface and the tangent plane of the conical surface is greater than 0° and less than 10°.

[0012] In the above technical solution, further, in the shock wave balancing tube, a throat is provided at the connection between the rear end of the shock wave generating chamber and the injection chamber, and the throat is connected to the injection hole for delivering the drug.

[0013] In the above technical solution, further, the medicine loading mechanism includes an injection needle, a driving mechanism and a transmission mechanism, and the driving mechanism acts on the injection needle through the transmission mechanism to control the medicine discharging action.

[0014] In the above technical solution, further, a supporting member is included, and the shell is detachably arranged on the supporting member.

[0015] In the above technical solution, further, the pilot solenoid valve is used to instantaneously accelerate the gas to 350-450 m / s.

[0016] In the above technical solution, further, in order to enhance the sealing after replacing the shock wave balancing tube, a stepped plug-in position is provided on the expansion chamber, a step is provided at one end of the shock wave balancing tube, and the step structure is installed on the plug-in position.

[0017] Compared with the prior art, the technical solution of the embodiment of the present application has the following beneficial effects:

[0018] The present application provides a component for generating shock wave energy at low pressure. This component generates a shock wave simultaneously with a high-speed gas jet. The shock wave is generated by reflecting and focusing ultrasonic energy, forming a sonic boom at the focal point, thereby generating a shock wave high-speed jet. This shock wave gas jet effect allows the atomized macromolecular particles of the drug solution to truly penetrate the skin, particularly the stratum corneum. This principle is completely different from that of traditional transdermal injectors.

[0019] Based on the above, it can be seen that the component that generates shock wave energy also generates ultra-high-speed airflow, but the pressure is relatively small, so it causes less damage to the skin and will not leave tiny blood holes, which can achieve non-invasive beauty. At the same time, the ultra-high-speed airflow can also improve the atomization ability of large-molecule drug liquids, thereby improving the ability to penetrate cells, allowing more drugs to be accurately delivered to collagen tissue cells about 1 mm away from the epidermis and penetrate the cell walls, thereby improving the absorption rate of the drugs and thus improving the beauty effect.

[0043] Figure 5 This is a schematic diagram of the assembly of the shock wave generating element and the shock wave balancing tube according to an embodiment of the present application.

[0044] like Figure 1-5As shown, an embodiment of the present application provides a shock wave transdermal injection device for cosmetic use, comprising a shell 5, a drug loading mechanism 6, a pilot solenoid valve 1, a shock wave generating component 2 and a shock wave balancing tube 3; the shell 5 provides space for the installation of other components and provides protection, and the drug loading mechanism 6, the pilot solenoid valve 1, the shock wave generating component 2 and the shock wave balancing tube 3 are all installed on the shell 5.

[0045] The shock wave generating element 2 is provided with a shock wave generating cavity front end 23;

[0046] The shock wave generating element 2 is provided with a piston sealing chamber 21, a transition chamber 22 and a shock wave generating chamber front end 23 which are connected in sequence; the shock wave generating chamber front end 23 is gradually expanded along the airflow direction; the piston sealing chamber 21 is used for adapting and connecting with a pilot solenoid valve.

[0047] Specifically, the pilot-operated solenoid valve includes a main valve and a pilot valve. The pilot valve is connected to the main valve through an inner cavity, and the pilot valve is used to drive the main valve to move and drive the metal piston to move.

[0048] The piston sealing cavity 21 is equipped with a tapered surface 25 that gradually contracts along the airflow direction. The pilot-operated solenoid valve main valve drives the metal piston, and the outer wall of the metal piston fits tightly against the metal tapered surface 25, preventing air leakage. The sealing system here is precisely designed and cannot include traditional sealing methods such as rubber rings.

[0049] In the above technical solution, further, the pilot solenoid valve has a separate software control system to fine-tune the parameters of the hardware matching error in the shock wave generator, and set up a set of algorithms to control the exhaust back pressure and the depth of skin penetration effect.

[0050] The shock wave balancing tube 3 is connected to the shock wave generating element 2. The shock wave balancing tube 3 is provided with a rear end 31 of a shock wave generating chamber that gradually contracts along the airflow direction and an injection chamber 33 that is connected to the rear end of the shock wave generating chamber. The inner diameter of the injection chamber 33 gradually expands along the airflow direction.

[0051] The inlet end of the pilot solenoid valve 1 is connected to the gas source via the gas pipe 4. The pilot solenoid valve 1 is used to sequentially inject low-pressure gas into the front end 23 of the shock wave generating chamber, the rear end 31 of the shock wave generating chamber and the injection chamber 33 within a preset time.

[0052] The throat of the shock wave balancing tube 3 near the shock wave generating element 2 is connected to the injection hole 36 for delivering medicine, and the medicine injection hole is connected to the medicine charging mechanism 6. The medicine charging mechanism 6 is connected to the injection hole of the shock wave balancing tube 3 through the medicine liquid pipe 7.

[0053] The medicine loading mechanism 6 is used to hold the medicine liquid and inject the medicine liquid into the throat.

[0054] Preferably, the charging mechanism 6 can be an injection needle, which is equipped with a drive motor and a transmission mechanism at the rear. Specifically, the injection push rod of the injection needle is connected to the drive motor through the transmission mechanism. The transmission mechanism can be a gear and rack transmission structure or a screw transmission structure. Of course, the present invention is not limited to this. The injection push rod of the injection needle can also be directly connected to a drive device such as a cylinder to achieve forward and backward movement.

[0055] The working principle of this injection instrument handpiece is as follows:

[0056] After the low-pressure gas rushes out instantly through the pilot solenoid valve 1, the low-pressure gas is formed. This gas expands and pressurizes in the shock wave generating chamber. At the same time, the conical surface of the shock wave generating chamber focuses the divergent sonic boom wave, forming a sonic boom wave in a single direction toward the inlet end of the shock wave balancing tube 3, causing the sonic boom wave finally ejected from the shock wave balancing tube 3 to reach maximum energy.

[0057] The shock wave gas jet coming out of the shock wave generating chamber first enters the tapered section of the injection chamber of the shock wave balancing tube 3. This tapered section is smoothly connected with the above-mentioned shock wave generating chamber in sequence to form a complete shock wave generating chamber. When the shock wave gas jet ejected from the complete shock wave generating chamber suddenly contracts at the throat 32, a high-energy focused shock wave is generated. There is an injection hole for introducing the liquid medicine above the throat 32. Each time it is fired, the liquid medicine will be injected into the hole with a corresponding dose and quickly atomized into nano-molecules. The shock wave gas jet coming out of the throat 32 carries the nano-atomized liquid medicine through the expansion section to reduce the pressure. At this time, the shock wave energy and the sonic boom remain unchanged, that is, what finally flows out of the shock wave balancing tube 3 is a low-pressure ultra-high-speed airflow. The ultra-high-speed flowing atomized medicine passes through the skin and penetrates the collagen cell membrane to enter the cells, completing drug delivery, that is, realizing needle-free drug delivery.

[0058] It can be seen that the use of the above-mentioned syringe handpiece can generate shock wave airflow and shock wave at the same time. The shock wave reflects and focuses the energy of the sonic boom, that is, it can generate shock wave and truly achieve the effect of penetrating the skin. Its principle is completely different from that of traditional syringes and is far superior to traditional syringes.

[0059] Based on the above, it can be seen that this injector handpiece can generate ultra-high-speed airflow, which causes less damage to the skin and will not leave tiny blood holes. At the same time, the ultra-high-speed airflow can also enhance the ability to penetrate cells, allowing more drugs to enter the cells, that is, more drugs can reach deep into the skin, thereby improving the absorption rate of drugs and thus improving the skin care effect.

[0060] In this embodiment, preferably, Figure 4 As shown, the injection chamber includes a shock wave generating chamber rear end 31, a throat 32 and an injection chamber 33 connected in sequence, and the shock wave generating chamber rear end 31 is arranged close to one side of the shock wave generating chamber.

[0061] According to the structure described above, the rear end of the shock wave balancing tube 3 is the rear end 31 of the shock wave generating cavity, which forms a complete shock wave generating cavity with the front end 21 of the shock wave generating cavity. The conical surface of the complete shock wave generating cavity focuses the divergent sonic boom wave to form a sonic boom wave in a single direction toward the inlet of the shock wave balancing tube 3, and makes the sonic boom wave at the outlet of the shock wave balancing tube 3 reach the maximum energy, so as to facilitate penetration of the cell membrane of the skin cells.

[0062] The middle of the shock wave balance tube 3 is the throat 32. The shock wave gas coming out of the complete shock wave generating chamber suddenly contracts in the throat 32, generating a high-energy focused shock wave. There is an injection hole for introducing the liquid medicine above the throat 32. Each time the gun is fired, the liquid medicine will be injected into the hole at a corresponding dose and quickly atomized into nano-molecules.

[0063] The front end of the shock wave balancing tube 3 is the injection chamber 33, which is the expansion zone. The shock wave gas coming out of the throat 32 carries the nano-atomized liquid medicine through the expansion zone, which will reduce the pressure. At this time, the shock wave airflow velocity and the sonic boom remain unchanged. The purpose of reducing the pressure is mainly to avoid the gas pressure from causing damage to the skin and human body, so that the use of this injection instrument handpiece is safer and more reliable. That is, the injection chamber 33 balances the pressure at the outlet of the shock wave balancing tube 3, so that the outlet pressure and the atmospheric pressure differ by plus or minus 0.5 MPa, while maintaining the airflow shock wave unchanged to protect the skin.

[0064] In this embodiment, preferably, the opening time of the pilot-operated solenoid valve 1 is 15 ms to 20 ms, so as to achieve rapid opening and generate high-speed airflow in a very short time.

[0065] In this embodiment, the pilot-operated solenoid valve 1 preferably comprises a main valve and a pilot valve, these two components being connected via the inner cavity of the valve body. Furthermore, the pilot-operated solenoid valve 1 is preferably a pilot-operated solenoid valve. Other components include a moving iron core, a stationary iron core, a solenoid coil, and a spring. When the pilot-operated solenoid valve is energized, electromagnetic force lifts the valve stem, opening the pilot valve port. At this point, pressure is relieved in the upper chamber of the solenoid valve through the pilot hole, creating a pressure differential around the main valve core, with lower pressure at the top and higher pressure at the bottom. Under this pressure differential, fluid pressure pushes the main valve core upward, opening the main valve port. When power is removed, the spring force and the weight of the main valve core cause the valve stem to return to its original position, closing the pilot hole and moving the main valve core downward, closing the main valve port. Pressure in the upper chamber of the solenoid valve increases, and fluid pressure pressurizes the main valve core, improving sealing. Through reasonable structural design and on / off control, a low-pressure gas is formed. Note that the main valve's spring and piston are closely related to controlling the energization time, significantly affecting the speed of sound.

[0066] The main valve ejects gas, which enters the shock wave generating chamber, forms a sonic boom in the shock wave generating chamber and enters the shock wave balancing tube 3 through reflection. The shock wave further forms a directional high-energy focused shock wave and shock wave airflow in the shock wave balancing tube 3.

[0067] The design of the shock wave generating cavity and the shock wave balancing tube 3 is based on the calculation of the Prandtl-Meyer angle function, as shown below:

[0068]

[0069] M is the air flow velocity, v is the deflection angle of the air flow along the inner wall of the tube, and γ is the constant (a parameter that affects the heat capacity ratio of the gas, such as air temperature).

[0070] Note: The design of the shock wave generating chamber has a great influence on whether a sonic boom can be formed; the design of the shock wave balancing tube 3, especially the rear end 31 of the shock wave generating chamber, has a great influence on whether the shock wave can be correctly focused, so it is necessary to focus on the design.

[0071] In this embodiment, preferably, Figure 3 As shown, the shock wave generating member 2 is threadedly connected to the pilot solenoid valve 1 .

[0072] According to the structure described above, the shock wave generating element 2 and the pilot solenoid valve 1 adopt a detachable connection structure, which is convenient for installation and disassembly, thereby facilitating subsequent operation and maintenance work.

[0073] Preferably, an outer wall of one end of the shock wave generating element 2 is formed with an external thread 24 , and the pilot solenoid valve 1 is formed with an interface with an internal thread, thereby enabling the shock wave generating element 2 and the pilot solenoid valve 1 to be threadedly connected.

[0074] Among them, preferably, the outer wall of the shock wave generating member 2 is stepped and staggered, which can avoid interference and collision with the pilot solenoid valve 1.

[0075] In this embodiment, preferably, Figure 3 and Figure 4 As shown, the shock wave balancing tube 3 is plugged into the shock wave generating component 2. Specifically, the shock wave generating component 2 is formed with a transition cavity 22 and a gradually expanding shock wave generating cavity front end 23. The transition cavity 22 is a circular cavity for plugging the shock wave generating component 2. The shock wave generating cavity front end 23 provides sufficient installation space for installing the shock wave balancing tube 3.

[0076] A sealing ring as described below is fixedly provided on the periphery of one end of the shock balance tube 3. Specifically, a mounting groove 34 is provided on the periphery of one end of the shock balance tube 3, and the sealing ring is disposed in the mounting groove 34.

[0077] One end of the shock wave balancing tube 3 provided with a sealing ring is inserted into the transition cavity 22 of the shock wave generating component 2, thereby realizing the assembly of the shock wave generating component 2 and the shock wave balancing tube 3. And it should be noted that the end of the shock wave balancing tube 3 is formed into a stepped plug-in structure. The advantage of this is that the step structure 35 is against the shock wave generating component 2, which plays a role in limiting the shock wave balancing tube 3.

[0078] Among them, preferably, the outer wall of the configuration component is cylindrical with regular shape, which is convenient for processing.

[0079] In this embodiment, preferably, a sealing ring is provided between the shock wave generating element 2 and the shock wave balancing tube 3 .

[0080] According to the structure described above, it can be seen that a sealing ring structure is provided between the shock wave generating element 2 and the shock wave balancing tube 3 to prevent leakage and ensure the air flow speed.

[0081] Preferably, the sealing ring is an O-ring.

[0082] In this embodiment, preferably, Figure 1 and Figure 2 As shown, the syringe handpiece further includes a gas pipe 4 , which is connected to the pilot-operated solenoid valve 1 .

[0083] According to the structure described above, the end of the gas pipe 4 away from the pilot solenoid valve 1 is used to connect to a low-pressure gas source. The pressure of the gas source can be 0.7 MPa. Of course, it is not limited to this and can be selected according to actual needs.

[0084] In addition, the types of gas sources can also be varied, for example, the gas source can be an air source, a nitrogen source or a helium source, and the gas source can be equipped with a pressure regulating valve to perform output pressure regulation to achieve the best effect.

[0085] Preferably, both ends of the conveying exchange member are provided with connectors, and the gas pipe 4 is respectively connected to the gas source and the pilot solenoid valve 1 through the two connectors.

[0086] In this embodiment, preferably, the shock wave transdermal injector further includes a supporting member, and the housing 5 is detachably disposed on the supporting member.

[0087] Based on the structure described above, it can be seen that the shock wave transdermal injection device can be placed on the supporting member to avoid direct contact with the desktop, which is cleaner and more hygienic.

[0088] The supporting member may be a supporting frame having a U-shaped opening, and the gun body may be arranged in the U-shaped opening.

[0089] Although the present application is disclosed as above, the present application is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined by the claims.
