Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a plasma therapy device for the waist and abdomen. Background Technology

[0002] Nitric oxide (NO) has significant medical value, not only effectively improving tissue blood circulation and metabolism, and eliminating inflammation and pain, but also accelerating the recovery of affected areas by improving local microcirculation and promoting angiogenesis. A plasma therapy device is a medical instrument that uses gas discharge technology to generate plasma with active nitric oxide as its main component.

[0003] In existing technologies, when plasma therapy devices are working, gas discharge generates a large amount of waste gas. If patients inhale excessive amounts of waste gas over a long period of time, it can cause harm to their bodies. Summary of the Invention

[0004] The purpose of this invention is to provide a plasma therapy device for the waist and abdomen that can effectively prevent patients from inhaling exhaust gases.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A plasma therapy device for the waist and abdomen, comprising:

[0007] Support frame;

[0008] The treatment head is mounted on the support frame and has a hollow groove and a fitting opening communicating with the hollow groove. The patient's waist or abdomen can fit into the fitting opening to form a closed treatment cavity with the hollow groove.

[0009] A plasma generator is installed on the treatment head and communicates with the hollow trough. The plasma gas generated by the discharge of the dielectric gas in the plasma generator and the exhaust gas can be injected into the hollow trough.

[0010] An exhaust gas collection device is connected to the hollow tank and can collect the gas inside the hollow tank.

[0011] Optionally, it also includes a telescopic rod, wherein the treatment head is rotatably connected to the support frame, the telescopic end of the telescopic rod is connected to the treatment head, the fixed end of the telescopic rod is connected to the support frame, and the telescopic rod can drive the treatment head to rotate around the support frame.

[0012] Optionally, the treatment head may also include a motion mechanism mounted on the treatment head, wherein the plasma generator is disposed on the motion mechanism and the motion mechanism is capable of driving the plasma generator to move on the treatment head.

[0013] Optionally, the motion mechanism includes a first moving mechanism and a second moving mechanism disposed on the first moving mechanism. The first moving mechanism is mounted on the treatment head, and the plasma generator is mounted on the second moving mechanism. The first moving mechanism can drive the second moving mechanism to move along a first direction, and the second moving mechanism can drive the plasma generator to move along a second direction.

[0014] Optionally, the hollow groove is provided with an internal opening, and a telescopic baffle is provided between the internal opening and the plasma generator. The telescopic baffle can seal the gap between the plasma generator and the internal opening. When the motion mechanism drives the plasma generator to move on the treatment head, the telescopic baffle can deform.

[0015] Optionally, the plasma generator includes:

[0016] The housing is provided with a primary air inlet, a secondary air inlet, and an air outlet, and the air outlet is connected to the hollow groove;

[0017] The discharge chamber is disposed inside the shell and is connected to the primary air inlet. The discharge chamber can ionize the medium gas flowing in from the primary air inlet into plasma gas.

[0018] The air ring is connected to the discharge chamber, the secondary air inlet, and the air outlet. The medium gas flowing into the air ring through the secondary air inlet can reduce the temperature of the gas flowing from the discharge chamber into the air ring. The gas in the air ring can be injected into the hollow trough from the air outlet.

[0019] Optionally, the exhaust gas collection device includes a corrugated pipe and an exhaust fan, the corrugated pipe being connected to the hollow trough, and the exhaust fan being mounted on the corrugated pipe.

[0020] Optionally, handrails are provided on both sides of the treatment head, and the handrails are slidably connected to the treatment head.

[0021] Optionally, it also includes a medium gas module connected to the plasma generator gas, the medium gas module being able to provide the medium gas to the plasma generator.

[0022] Optionally, the system also includes a lifting column and a seat, with the bottom end of the lifting column connected to the support frame and the top end of the lifting column connected to the seat.

[0023] Beneficial effects:

[0024] The lumbar and abdominal plasma therapy device provided by this invention has a hollow groove and a fitting opening communicating with the hollow groove on the treatment head. When the patient's waist or abdomen rests against the treatment head to receive treatment, the patient's waist or abdomen fits perfectly with the fitting opening to form a sealed treatment cavity with the hollow groove. The plasma gas ejected from the plasma generator is confined within this treatment cavity to treat the patient. At the same time, the exhaust gas collection device collects the gas generated by the discharge of the dielectric gas, thereby ensuring that the exhaust gas does not diffuse into the external environment of the treatment cavity to ensure the patient's safety. Moreover, this lumbar and abdominal plasma therapy device has a simple structure and is easy to use. Attached Figure Description

[0044] Reference Figures 1 to 3 As shown, this embodiment provides a lumbar and abdominal plasma therapy device, including a support frame 100, a treatment head 200, a plasma generator 300, and an exhaust gas collection device 400. The treatment head 200 is mounted on the support frame 100 and has a hollow groove 210 and a fitting opening 220 communicating with the hollow groove 210. The patient's waist or abdomen can fit into the fitting opening 220 to form a sealed treatment cavity with the hollow groove 210. The plasma generator 300 is mounted on the treatment head 200 and communicates with the hollow groove 210. The plasma gas generated by the discharge of the dielectric gas in the plasma generator 300 and the exhaust gas can be injected into the hollow groove 210. The exhaust gas collection device 400 is communicated with the hollow groove 210 and can collect the gas in the hollow groove 210.

[0045] In this embodiment, the treatment head 200 is provided with a hollow groove 210 and a fitting opening 220 communicating with the hollow groove 210. When the patient's waist or abdomen rests on the treatment head 200 to receive treatment, the patient's waist or abdomen fits perfectly with the fitting opening 220 to form a sealed treatment cavity with the hollow groove 210. The plasma gas ejected by the plasma generator 300 is confined within this treatment cavity to treat the patient. At the same time, the exhaust gas collection device 400 collects the gas generated by the discharge of the dielectric gas, thereby ensuring that the exhaust gas does not diffuse into the environment outside the treatment cavity to ensure the patient's safety. Moreover, this waist and abdomen plasma therapy device has a simple structure and is easy to use.

[0046] In this embodiment, reference is made to Figure 2As shown, the lumbar and abdominal plasma therapy device also includes a medium gas module 800 connected to the plasma generator 300. The medium gas module 800 can provide medium gas to the plasma generator 300. Specifically, the medium gas can be, but is not limited to, an inert gas, nitrogen, or air, and will not be further limited here.

[0047] In this embodiment, reference continues to be made to... Figure 2 As shown, the lumbar and abdominal plasma therapy device also includes a control module 1100. The plasma generator 300 and the exhaust gas collection device 400 are all electrically connected to the control module 1100. The control module 1100 controls the operation of the plasma generator 300 and the exhaust gas collection device 400. The structure, connection method, and control method of the control module 1100 are existing technologies and will not be described in detail here.

[0048] In this embodiment, reference continues to be made to... Figure 2 As shown, the lumbar and abdominal plasma therapy device also includes a power module 1200, a plasma generator 300, an exhaust gas collection device 400, and a controller, all of which are electrically connected to the power module 1200. The power module 1200 supplies power to the electrical components of the lumbar and abdominal plasma therapy device.

[0049] In this embodiment, reference continues to be made to... Figure 3 As shown, a sealing gasket 221 is provided at the opening 220. When the patient is receiving treatment, the patient's waist or abdomen is close to the first opening and in close contact with the sealing gasket 221, which can effectively ensure the airtightness of the treatment cavity and prevent the gas ejected from the plasma generator 300 from spreading into the environment, so as to ensure that the patient does not inhale excessive exhaust gas.

[0050] Furthermore, continue to refer to Figure 3 The hollow trough 210 has an exhaust gas collection port 211 on its wall, which is connected to the exhaust gas collection device 400. Furthermore, there are two exhaust gas collection ports 211, which are symmetrically arranged on opposite walls of the hollow trough 210 to accelerate the discharge of waste gas from the hollow trough 210.

[0051] In this embodiment, reference continues to be made to... Figure 3 The treatment head 200 is equipped with armrests 230 on both sides, and the armrests 230 are slidably connected to the treatment head 200. Specifically, the armrests 230 can move along the width of the treatment head 200, so that the patient's arm can be comfortably placed on the armrests 230 when receiving treatment.

[0052] Specifically, the treatment head 200 is covered by a head shell 240, and the armrest 230 is slidably connected to the head shell 240, which makes the appearance of the lumbar and abdominal plasma therapy device more aesthetically pleasing and prevents the patient from touching other components on the treatment head 200, thus ensuring the patient's safety.

[0053] Furthermore, the head shell 240 can also be equipped with a control screen 251 and a hand controller 252.

Specifically, the control screen 251 is located on the top of the head shell 240, and the hand controller 252 is located on one side of the head shell 240. Both the control screen 251 and the hand controller 252 are electrically connected to the control module 1100, and the control screen 251 and the hand controller 252 control the operation of the plasma generator 300 and the exhaust gas collection device 400 through the control module 1100. Furthermore, both the control screen 251 and the hand controller 252 are electrically connected to the power module 1200.

[0054] Furthermore, continue to refer to Figure 1 As shown, a support shell 110 is also provided on the support frame 100. A connecting pipe 120 is provided between the support shell 110 and the head shell 240. A protective cavity is formed between the support shell 110, the connecting pipe 120, and the head shell 240. The exhaust gas collection device 400, at least part of the support frame 100, the treatment head 200, and other components are all placed in the protective cavity. This makes the appearance of the lumbar and abdominal plasma therapy device more aesthetically pleasing and effectively protects the components inside the protective cavity. It also effectively prevents personnel from contacting the components inside the protective cavity, ensuring personnel safety. Specifically, the connecting pipe 120 may be, but is not limited to, a telescopic connecting pipe 120.

[0055] In this embodiment, reference is made to Figure 4 As shown, the exhaust gas collection device 400 includes a corrugated pipe 410 and an exhaust fan 420. The corrugated pipe 410 is connected to the hollow trough 210, and the exhaust fan 420 is mounted on the corrugated pipe 410. The exhaust fan 420 is connected to the hollow trough 210 through the corrugated pipe 410. The lumbar plasma therapy device uses the exhaust fan 420 to draw out the exhaust gas from the hollow trough 210. The exhaust gas collection device 400 has a simple structure and is easy to install. Specifically, one end of the corrugated pipe 410 is connected to the exhaust gas collection port 211, and the other end of the corrugated pipe 410 is connected to the exhaust gas treatment device (not shown in the figure). The drawn-out exhaust gas is discharged from the corrugated pipe 410 into the exhaust gas treatment device for treatment. The exhaust gas treatment device is existing technology and will not be described in detail here. Specifically, the exhaust fan 420 is electrically connected to the control module 1100. The control panel 251 and the hand controller 252 can control the operation of the exhaust fan 420 through the control module 1100. Furthermore, the exhaust fan 420 is electrically connected to the power module 1200.

[0056] In this embodiment, reference continues to be made to... Figure 4As shown, the lumbar and abdominal plasma therapy device also includes a telescopic rod 510. The treatment head 200 is rotatably connected to the support frame 100. The telescopic end of the telescopic rod 510 is connected to the treatment head 200, and the fixed end of the telescopic rod 510 is connected to the support frame 100. The telescopic rod 510 can drive the treatment head 200 to rotate around the support frame 100. Preferably, the telescopic rod 510 can be, but is not limited to, an electric push rod. Electric push rods are existing technology and will not be described in detail here. In this embodiment, the lumbar and abdominal plasma therapy device moves the telescopic end of the telescopic rod 510 within the fixed end to push the treatment head 200 to rotate around the support frame 100, thereby adjusting the angle of the treatment head 200 so that the patient's waist or abdomen is suitable for fitting with the fitting opening 220 of the treatment head 200 to form a sealed treatment cavity with the hollow groove 210. Specifically, the telescopic rod 510 is electrically connected to the control module 1100, and the control screen 251 and the hand controller 252 can control the movement of the telescopic rod 510 through the control module 1100. Furthermore, the telescopic pole 510 is electrically connected to the power module 1200.

Furthermore, the rotatable connection between the treatment head 200 and the support frame 100 can also be in other forms, which will not be described in detail here.

[0058] In this embodiment, reference continues to be made to... Figure 4 As shown, the lumbar and abdominal plasma therapy device also includes a motion mechanism 600 mounted on the treatment head 200. A plasma generator 300 is disposed on the motion mechanism 600. The motion mechanism 600 can drive the plasma generator 300 to move on the treatment head 200, so that the plasma generator 300 can spray plasma gas onto the patient's affected area. In this embodiment, when the patient's affected area is small, the plasma generator 300 can either continuously spray plasma gas while remaining stationary on the affected area. When the patient's affected area is large, the motion mechanism 600 drives the plasma generator 300 to move, so that the plasma generator 300 can evenly spray plasma gas onto the patient's affected area. Specifically, the motion mechanism 600 is electrically connected to the control module 1100, and the control screen 251 and the hand controller 252 can control the movement of the motion mechanism 600 through the control module 1100. Furthermore, the motion mechanism 600 is electrically connected to the power module 1200.

[0059] Specifically, the motion mechanism 600 includes a first moving mechanism 610 and a second moving mechanism 620 disposed on the first moving mechanism 610. The first moving mechanism 610 is mounted on the treatment head 200, and the plasma generator 300 is mounted on the second moving mechanism 620. The first moving mechanism 610 can drive the second moving mechanism 620 to move along a first direction, and the second moving mechanism 620 can drive the plasma generator 300 to move along a second direction. Further, the first direction can be perpendicular to the second direction, or it can be at other angles to the second direction; no further limitations are made here. Preferably, the first direction is the height direction of the treatment head 200, and the second direction is the length direction of the treatment head 200. In this embodiment, the motion mechanism 600 enables the plasma gas ejected by the plasma generator 300 to reach any position on the patient's waist or abdomen corresponding to the hollow groove 210.

[0060] Further, the first moving mechanism 610 includes a first guide rail 611 disposed at the rear of the treatment head 200, a first slider 612 slidably connected to the first guide rail 611, and a first motor 613 driving the first slider 612 to slide on the first guide rail 611. The first moving mechanism 610 is mounted on the first slider 612. Specifically, at least one first slide rail is provided and extends along the height direction of the treatment head 200. Preferably, two first slide rails are provided and symmetrically disposed on both sides of the rear of the treatment head 200, with at least one first slider 612 disposed on each first slide rail. Further, the first motor 613 can be driven to the first slider 612 through a screw and nut mechanism. The first motor 613 can also be driven to the first slider 612 through other transmission mechanisms, which will not be further limited here. Further, the method of driving the first motor 613 to the first slider 612 through a screw and nut mechanism is prior art and will not be described in detail here. In this embodiment, the first motor 613 drives the first slider 612 to move on the first slide rail, thereby causing the second moving mechanism 620 to move along the height direction of the treatment head 200, so that the plasma generator 300 moves along the height direction of the treatment head 200. Specifically, the first motor 613 is electrically connected to the control module 1100, and the control screen 251 and the hand controller 252 can control the movement of the first motor 613 through the control module 1100. Further, the first motor 613 is electrically connected to the power module 1200.

[0061] Further, the second moving mechanism 620 includes a second guide rail 621 mounted on the first slider 612, a second slider 622 slidably connected to the second guide rail 621, and a second motor 623 driving the second slider 622 to slide on the second guide rail 621. The second guide rail 621 extends along the length of the treatment head 200, and the plasma generator 300 is mounted on the second slider 622. Further, the second motor 623 can be driven to the second slider 622 via a screw-nut mechanism, or it can be driven to the second slider 622 via other transmission mechanisms; no further limitations are made here. Further, the method of driving the second motor 623 to the second slider 622 via a screw-nut mechanism is existing technology and will not be described in detail here. In this embodiment, the second motor 623 drives the second slider 622 to move on the second guide rail, thereby causing the plasma generator 300 to move along the length of the treatment head 200. Specifically, the second motor 623 is electrically connected to the control module 1100, and the control panel 251 and the hand controller 252 can control the movement of the second motor 623 through the control module 1100. Furthermore, the second motor 623 is electrically connected to the power module 1200.

[0062] Furthermore, referring to Figure 5 As shown, the hollow groove 210 has an internal opening, and a telescopic baffle 700 is provided between the internal opening and the plasma generator 300. The telescopic baffle 700 can seal the gap between the plasma generator 300 and the internal opening. When the motion mechanism 600 drives the plasma generator 300 to move on the treatment head 200, the telescopic baffle 700 can deform. Specifically, the internal opening is located at the bottom of the hollow groove 210. In this embodiment, the telescopic baffle 700 deforms as the plasma generator 300 moves, ensuring the airtightness of the hollow cavity at all times, effectively preventing gas in the treatment cavity from flowing into the external environment to ensure the patient's safety.

[0063] Furthermore, the material of the telescopic baffle 700 is not limited to silicone, and its shape is not limited to a folded state; no further restrictions will be imposed here.

[0064] In this embodiment, reference is made to Figure 6As shown, the lumbar and abdominal plasma therapy device also includes a lifting column 910 and a seat 920. The bottom end of the lifting column 910 is connected to the support frame 100, and the top end of the lifting column 910 is connected to the seat 920. The height of the seat 920 can be adjusted by raising and lowering the lifting column 910, allowing patients of different heights to use the lumbar and abdominal plasma therapy device. Specifically, the lifting column 910 can be, but is not limited to, an electric lifting column 910. Electric lifting columns 910 are existing technology and will not be described in detail here. Specifically, the lifting column 910 is electrically connected to the control module 1100, and the control screen 251 and the hand controller 252 can control the raising and lowering of the lifting column 910 through the control module 1100. Further, the lifting column 910 is electrically connected to the power module 1200.

[0065] In this embodiment, reference is made to Figure 7 As shown, the plasma generator 300 includes a housing 310, a discharge chamber 320, and a wind ring 330. The housing 310 is provided with a primary air inlet 3111, a secondary air inlet 3112, and an air outlet 3151. The air outlet 3151 is connected to the hollow trough 210. The discharge chamber 320 is disposed inside the housing 310 and is connected to the primary air inlet 3111. The discharge chamber 320 can ionize the medium gas flowing in from the primary air inlet 3111 to produce plasma gas. The discharge chamber 320, the secondary air inlet 3112, and the air outlet 3151 are all connected to the wind ring 330. The medium gas flowing into the wind ring 330 from the secondary air inlet 3112 can reduce the temperature of the gas flowing from the discharge chamber 320 into the wind ring 330. The gas in the wind ring 330 can be ejected from the air outlet 3151 into the hollow trough 210. Specifically, both the primary air inlet 3111 and the secondary air inlet 3112 are connected to the plasma generator 300. In this embodiment, the medium gas flowing into the air ring 330 through the secondary air inlet 3112 reduces the temperature of the gas flowing from the discharge chamber 320 into the air ring 330, ensuring that the gas sprayed from the outlet 3151 into the hollow trough 210 will not overheat and burn the patient, thus providing the patient with a better treatment experience.

[0066] Specifically, a first mounting plate 311 is provided inside the housing 310. A mounting groove 312 is provided on one side of the first mounting plate 311, and an insulating ring 313 is provided on the other side of the first mounting plate 311. A sealed first cavity is formed between the insulating ring 313 and the first mounting plate 311. A cathode 321 is installed in the mounting groove 312. The cathode 321 is columnar. The end of the cathode 321 passes through the bottom of the mounting groove 312 and is placed inside the insulating ring 313. An anode 322 is installed in the insulating ring 313. The anode 322 is annular. The end of the cathode 321 is placed inside the annular anode 322. The anode 322 and the outer surface of the bottom of the mounting groove 312 form a discharge chamber 320. Furthermore, the anode 322 has multiple first vent holes circumferentially arranged, which are located inside the insulating ring 313. The primary air inlet 3111 is connected to the insulating ring 313. The dielectric gas flowing in from the primary air inlet 3111 passes through the insulating ring 313 and the first vent holes in sequence and enters the discharge chamber 320 for ionization. Specifically, the primary air inlet 3111 is located on the first support plate.

[0067] Furthermore, a second mounting plate 314 is disposed within the housing 310, forming a sealed second cavity between the first mounting plate 311 and the second mounting plate 314. An insulating ring 313 is disposed within the second cavity, and the bottom surface of the insulating ring 313 passes through the side of the anode 322 facing away from the first mounting plate 311 and is placed within the second cavity. A fan ring 330 is installed within the second cavity, with its first end sleeved on the anode 322 and abutting against the outer surface of the bottom surface of the insulating ring 313. Furthermore, the fan ring 330 has multiple second vent holes circumferentially arranged within the second cavity. A secondary air inlet 3112 communicates with the second cavity, and the medium gas flowing in from the secondary air inlet 3112 sequentially enters the fan ring 330 through the second cavity and the second vent holes to cool the gas temperature within the fan ring 330. Specifically, the secondary air inlet 3112 is disposed on the first support plate.

[0068] Specifically, a third mounting plate 315 is provided on the side of the second mounting plate 314 inside the housing 310 facing away from the first mounting plate 311, forming a sealed third cavity between the second mounting plate 314 and the third mounting plate 315. An air outlet 3151 is mounted on the third mounting plate 315. Further, a silencer pipe 340 is installed between the second mounting plate 314 and the third mounting plate 315. One end of the silencer pipe 340 is connected to the air ring 330, and the other end is connected to the air outlet 3151. Specifically, the second end of the air ring 330 passes through the second mounting plate 314 and is connected to the silencer pipe 340. In this embodiment, the gas in the air ring 330 is ejected from the air outlet 3151 through the silencer pipe 340, which can effectively reduce the sound of gas flow. The end of the silencer pipe 340 facing the air ring 330 is conical, which can effectively gather the gas in the silencer pipe 340, so that the gas ejected from the air outlet 3151 has a faster speed, so that the plasma gas can directly act on the patient's affected area, avoiding the plasma gas being collected by the exhaust gas collection device 400 before it acts on the patient, which would cause waste of plasma gas and reduce the efficacy of the lumbar and abdominal plasma therapy device.

[0069] Furthermore, the plasma generator 300 also includes a distance sensor 350, which can monitor the distance between the generator nozzle and the patient's skin in real time when the patient receives treatment. Specifically, a cable reel 316 is provided inside the housing 310. The cable reel 316 is located at the edge of the housing 310 and passes through the first mounting plate 311, the second mounting plate 314, and the third mounting plate 315. The distance sensor 350 is installed in the end of the cable reel 316 facing away from the first mounting plate 311, and the cable of the distance sensor 350 passes through the cable reel 316 and is led out from the end of the cable reel 316 facing away from the distance sensor 350, making the plasma generator 300 compact in structure.

[0070] Furthermore, the plasma generator 300 also includes a temperature sensor 360, which can monitor the temperature of the plasma gas at the outlet 3151 in real time when the patient receives treatment. Specifically, a mounting hole is provided on the side wall of the silencer tube 340 facing away from the air ring 330. The temperature sensor 360 is installed in the mounting hole, and the cable of the temperature sensor 360 passes through the side wall of the cable reel 316 in the third cavity, is placed inside the cable reel 316, and is led out from the end of the cable reel 316 facing away from the distance sensor 350, making the structure of the plasma generator 300 more compact.

[0071] For example, firstly, the operator adjusts the height of the lifting column 910 via the control panel 251 or the hand controller 252 to make the height of the seat 920 suitable for the patient, and the patient sits on the seat 920; then, the operator controls the movement of the telescopic rod 510 via the control panel 251 or the hand controller 252 to make the patient's waist or abdomen perfectly fit the fitting opening 220; finally, the operator turns on the exhaust fan 420 via the control panel 251 or the hand controller 252, and the controller automatically controls the movement of the motion mechanism 600 to adjust the position of the plasma generator 300 so that the plasma generator 300 sprays plasma gas evenly to the patient's affected area.
