Description

Technical Field

[0001] The present disclosure relates to the technical field of medical equipment, and in particular to a plasma jet array generating device and system. Background Art

[0002] In the 1890s, Johnson & Johnson developed a commercial low-pressure hydrogen peroxide plasma sterilizer, which quickly gained popularity in hospitals for low-temperature, rapid sterilization of precision medical devices and specialized materials. However, the generation of low-pressure plasmas required expensive and complex vacuum systems, limiting their application. Atmospheric pressure non-equilibrium plasmas avoid complex and expensive vacuum systems, but the gas temperature is relatively high, making it difficult to transition to non-uniform discharges and arc discharge lamps. Methods such as dielectric barrier discharge and microdischarge can effectively overcome this difficulty, enabling the generation of uniform, low-temperature non-equilibrium plasmas at atmospheric pressure. Furthermore, placing some samples within the discharge gap can affect discharge stability. If placed outside the discharge gap, gas flow transports active particles to the sample surface, but charged particles and some short-lived active particles disappear before reaching the sample. The atmospheric pressure non-plasma jet (N-APPJ) generates atmospheric pressure non-equilibrium plasmas in an open space, rather than within the gap. Plasma medicine and N-APPJ have developed almost synchronously, with applications encompassing skin disinfection and sterilization, rapid wound healing, rapid blood coagulation, treatment of skin diseases, apoptosis, and cancer. Traditional low-temperature plasma discharge devices require an external high-voltage power supply, making them difficult for non-specialists to use. Furthermore, while current plasma jet array generators can produce a uniform and stable jet, their effective area is still significantly limited. Current technology cannot achieve fully targeted treatment for small areas like the underarms and nostrils, larger areas like the chest and back, or uneven areas like the thighs and buttocks.

[0036] As Figure 1a , Figure 1b , Figure 2 and Figure 3As shown, a plasma jet array generating device 100 includes multiple plasma generating structures 110 for generating plasma. The plasma generating structures 110 have first outlets 111 facing the same direction, such as simultaneously facing the first direction A. The first electrodes 115 in the multiple plasma generating structures 110 are connected in parallel to an external power source via a wire inlet 127, and power is controlled by a power supply 113. In some embodiments, the power supply 113 may be disposed within the second housing.

[0037] More specifically, if Figure 3 As shown, the plasma generating structure 110 includes a first housing 112, a first electrode 114, and a second electrode 115. The first electrode 114 and the second electrode 115 can be powered by an external power supply 135. A first cavity 116 is defined within the first housing 112. The first housing 112 also includes a first air inlet 118. A first outlet 111 is disposed within the first housing 112. The first air inlet 118 and the first outlet 111 are each connected to the first cavity 116. The second electrode 115 is disposed within the first cavity 116. The first electrode 114 is disposed within the first housing 112. A gap exists between the first electrode 114 and the second electrode 115. The first electrode 114 and the second electrode 115 cooperate to convert the gas between the first electrode 114 and the second electrode 115 into plasma. The generated plasma is discharged from the first housing 112 through the first outlet 111.

[0038] It should be understood that due to the different gases introduced into the first air inlet 118 and the different voltages output by the power supply 113, the plasmas eventually output from the outlet will also be different. Therefore, the user can adjust the gas introduced into the first air inlet 118 and the voltage output by the power supply 113 according to the actual situation to obtain different plasmas to achieve functions such as beauty, freckle removal, and treatment. Figure 2 As shown, the first housing 112 is formed with a fixing slot 117 to fix the second electrode 115, but in other embodiments, the user can adjust the way the second electrode 115 is fixed to the first housing 112 according to the situation, and the present disclosure does not impose any specific limitation.

[0039] Optional, such as Figure 1a 、 Figure 1b as well as Figure 2As shown, the plasma jet array generating device 100 further includes a second housing 120. A portion of the plasma generating structure 110 is disposed within the second housing 120. The second housing 120 is provided with a first opening 121, which corresponds one-to-one with each plasma generating structure 110. One end of the plasma generating structure 110 having a first outlet 111 can pass through the corresponding first opening 121, such that the first outlet 111 is located outside the second housing 120. The second housing 120 is provided with a second air inlet 122, which communicates with the first air inlet 118 of the plurality of plasma generating structures 110. Gas is supplied to the plurality of plasma generating structures 110 through the single second air inlet 122, facilitating the establishment of an air supply path for the plasma jet array generating device 100. Specifically, the second shell 120 includes a shell body 130, a top cover 140 and a bottom cover 150. The top cover 140, the bottom cover 150 and the shell body 130 cooperate with each other to form a cavity for accommodating the plasma jet array generating device 100; wherein, the second air inlet 122 is arranged on the shell body 130, and the first opening 121 is arranged on the bottom cover 150.

[0040] It should be understood that the second housing 120 may be Figure 1a as well as Figure 1b cylindrical shape as shown, or as Figure 4 as well as Figure 5 The square-like structure shown in the figure is not specifically limited in the present disclosure. The shape of the plasma generating structure 110 can also be adjusted according to the situation, such as Figure 2 and Figure 3 As shown, the plasma generating structure 110 is relatively slim and slender, but in some embodiments, the plasma generating structure 110 can be as Figure 5 as well as Figure 6 The plasma generating structure 110 may have various shapes, and the present disclosure is not limited thereto.

[0041] like Figure 4 as well as Figure 5 As shown, the first opening 121 is provided with a first switch member 123. Figure 1d as well as Figure 1eAs shown, the first switch element 123 includes a first body 124 and a plug 125 connected to the first body 124. The first body 124 is fixed to the second housing 120 and located outside the second housing 120. The first body 124 defines a second cavity 170. One end of the second cavity 170 communicates with the corresponding first opening 121, and the second end of the second cavity 170 communicates with the outside world. Therefore, when plasma wishes to exit the second housing 120 through the first opening 121 to the outside world, it must pass through the second cavity 170. The plug 125 is detachably connected to the second end of the second cavity 170. When the plug 125 is placed into the second end of the second cavity 170, the first switch element 123 is closed. The cooperation between the second housing 120, the first body 124 of the first switch element 123, and the plug 125 prevents plasma from leaving the second housing 120 through the first opening 121 corresponding to the first switch element 123. When the plug 125 is inserted into the second end of the second cavity 170, the first switch 123 effectively blocks the plasma from leaving the second housing 120 through the first opening 121 corresponding to the first switch 123. This arrangement prevents the plasma generated by the plasma generating structure 110 from leaking when the plug 125 is inserted into the second end of the second cavity 170. When the plasma is needed, the plug 125 can be removed to allow the plasma to escape from the second end of the second cavity 170. It should be understood that since the first switch 123 corresponds one-to-one with the first opening 121, and the plasma generating structure 110 corresponds one-to-one with the first opening 121, the first switch 123 also corresponds one-to-one with the plasma generating structure 110.

[0042] Optionally, the first shell 112 of each plasma generating structure 110 extends along the first direction A, and the first shell 112 is moved along the first direction A to push the plug 125 away from the second end of the second cavity 170, wherein the first direction A is perpendicular to the second plane.

[0043] Optionally, the plasma jet array generating device 100 further includes a barrier 126, which interconnects the first housings 112 of the plasma generating structures 110. The first housing 112, the barrier 126, and the second housing 120 cooperate to form a third cavity 160. The second air inlet 122 communicates with the first air inlet 118 through the third cavity 160. The first housing 112, the barrier 126, and the second housing 120 cooperate to restrict gas from entering and exiting the third cavity 160 only through the first air inlet 118 and the second air inlet 122. First, because the barrier 126 interconnects the first housings 112 of the plasma generating structures 110, it is convenient for a user to move the plasma generating structures 110 together. Secondly, the barrier 126 restricts the gas in the third cavity 160 from flowing through the gaps between the first shells 112 , thereby better guiding the gas entering the third cavity 160 from the second air inlet 122 to enter the first shell 112 more quickly from the first air inlet 118 .

[0044] It should be understood that if Figure 1b As shown, a wire access port 127 may be provided on the outside of the second housing 120 to facilitate access to the interior of the second housing 120 from outside the second housing 120. Furthermore, a button 128 may be provided on the outside of the second housing 120. This button 128 is connected to the barrier 126. Pushing the button 128 can also push the barrier 126 and the plasma generating structures 110 secured thereto. Ultimately, the plasma generating structures 110 push the plug 125, causing it to disengage from the second cavity 170. Specifically, the button 128 is provided on the top cover 140, which is provided with a button hole 129 for receiving the button 128. The button 128 includes a pressing portion 1281 and a pushing portion 1282. The pressing portion 1281 is located outside the second housing 120, while one end of the pushing portion 1282 is connected to the pressing portion 1281, and the other end of the pushing portion is connected to the barrier 126. The user can move the pressing portion 1281 outside the second housing 120 to drive the pushing portion 1282 and the blocking member 126 to move, thereby driving the plasma generating structures 110 to move.

[0045] In addition, if Figure 7 As shown, a plasma jet array generating system 1000 includes a plurality of the above-mentioned plasma jet array generating devices, and the plasma jet array generating devices 100 are sequentially connected to each other.

[0046] Optional, such as Figure 8As shown, the plasma jet array generating devices 100 are connected by flexible materials. By using flexible materials to connect the plasma jet array generating devices 100, the plasma jet array generating system 1000 can be adjusted to a corresponding shape according to the different parts of the body being treated, which greatly improves the treatment efficiency and makes the treatment effect better. For example, it can be bent according to the different contours of the treatment part, such as the thigh, chest, buttocks and other parts of the body. Moreover, according to the different arrangements of the plasma jet array generating devices, the plasma jet array generating system 1000 can not only achieve horizontal bending, but also achieve longitudinal bending, which greatly improves the flexibility of the large-area plasma jet array generating device 100. The flexible material can be polyethylene or polyvinyl chloride.

[0047] Optionally, the plasma jet array generating system 1000 further includes a processing unit, and each plasma jet array generating device 100 is further provided with a camera 200. The processing unit is signal-connected to the camera 200 of each plasma jet array generating device 100, and the processing unit is connected to the power supply 113 of each plasma generating structure 110. Specifically, the camera 200 can automatically identify the active area, and the processing unit activates the plasma jet array generating device 100 at the corresponding position based on the signal fed back by the camera 200, releasing the plasma jet for treatment. The camera 200 can be a camera or other similar sensor. The processing unit can be a computer, CPU, single-chip microcomputer, or other device with data processing capabilities.

[0048] This disclosure discloses a device and system for generating localized and large-area plasma jet arrays, suitable for applications in therapeutics and aesthetic medicine. The flexible design not only allows for application to various locations but also allows for bending and adjusting to the desired shape based on the specific location of the target, significantly improving treatment efficiency and achieving enhanced therapeutic results. Furthermore, an accompanying camera 200 can identify the target area and activate the plasma jet array generator in that specific area, making treatment more targeted and enhancing the device's flexibility during treatment.

Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein with equivalents; and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present disclosure.
