Description

Technical Field

[0001] This invention relates to a plasma therapy device with a treatment chamber, belonging to the field of plasma medical equipment technology. Background Technology

[0002] Plasma is the fourth state of matter, after solid, liquid, and gas, and 99% of the matter in the universe is in this ionized state. Research data from both domestic and international sources shows that plasma has already demonstrated significant application value in sterilization, disinfection, blood clotting, dental applications, wound healing, and the treatment of skin diseases, including melanoma. In the future, plasma may become an indispensable tool in the treatment of certain diseases. The air plasma therapy head uses air as the working ionization medium, directly ionizing the airflow through high-frequency, high-voltage discharge to produce highly reactive NO. Reactive NO refers to NO molecules in an excited state, some of which carry a positive charge (NO...). + ) or negative charge (NO - NO molecules, with their highly reactive internal atoms, readily react chemically with other substances, releasing a significant amount of energy during the process of stabilizing. This highly reactive NO readily interacts with skin cells in redox reactions, activating immune factors and promoting disease recovery. Since 2005, various medical research institutions have reported successful treatments using cold plasma (CAP) for acute or chronic infected wounds, pruritus, shingles, and other infectious or superinfectious skin diseases. Furthermore, plasma application is non-contact and painless, with short treatment times and no allergic reactions; to date, no bacterial resistance or other side effects have been observed.

[0003] Some studies have shown that bacteria and fungi, similar to biofilms, viruses, and spores, can be killed very effectively with cold plasma. In particular, dangerous MRSA bacteria, such as *Georgia radiodurans* or *Staphylococcus aureus*, as well as other human pathogens such as *Listeria*, *Salmonella*, or *Escherichia coli* (EHEC), can be killed within seconds. CAP has also been successfully used in other medical fields, such as oral and maxillofacial surgery or cardiac surgery. In Germany, since 2013, the first plasma jetters approved for treating difficult-to-heal wounds and pathogen-induced skin diseases have been available. This device, called kINPen, is used to treat chronic wounds and pathogen-based skin and skin appendage diseases. The application prospects of plasma in the medical field are becoming increasingly clear, widespread, and rapidly developing. To facilitate the use of plasma in multiple diseases and lesion sites, it is essential to vigorously develop specialized, multifunctional, and automated medical devices. Summary of the Invention

[0004] In view of the above-mentioned problems of the prior art, the present invention provides a plasma therapy device with a treatment chamber.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0006] A plasma therapy device with a treatment chamber includes a treatment bed and a treatment chamber mounted on the treatment bed. The treatment chamber can reciprocate along the length of the treatment bed. A plasma treatment head is provided inside the treatment chamber. The plasma treatment head can reciprocate along the Y-axis and Z-axis within the treatment chamber. The plasma treatment head can rotate around the X-axis and Z-axis within the treatment chamber.

[0007] Based on the above technical solution, the present invention can also be improved as follows:

[0008] Furthermore, the treatment bed includes a bed frame, on which a treatment chamber reciprocating drive mechanism is provided. The treatment chamber reciprocating drive mechanism includes a lead screw and a lead screw nut. The lead screw is rotatably mounted on the bed frame, and the lead screw nut is mounted on the lead screw. The lead screw nut is fixedly connected to the treatment chamber, and the drive motor is drivenly connected to the lead screw.

[0009] By adopting the above-mentioned further technical solution, the drive motor drives the lead screw to rotate, and the lead screw nut to move linearly, causing the treatment chamber to move along the length of the treatment chamber. The reciprocating movement of the treatment chamber along the length of the treatment bed not only reduces the size of the equipment, but also ensures that the plasma treatment head can cover the patient from head to toe within the irradiation range of the plasma head, reducing the patient's own movement, and is especially convenient for patients with other auxiliary medical devices.

[0010] Furthermore, the bottom of the treatment chamber is provided with a base plate, which is fixedly connected to the lead screw nut.

[0011] By adopting the above-mentioned further technical solution, the treatment chamber is connected to the lead screw nut via a base plate. The base plate can be connected to the lead screw nut from below the treatment bed without affecting the normal use of the treatment bed.

[0012] Furthermore, the reciprocating drive mechanism of the treatment chamber also includes a treatment chamber linear guide rail and a slider. The treatment chamber linear guide rail is installed on the bed frame, the slider is installed on the treatment chamber linear guide rail, and the slider is fixedly connected to the base plate.

[0013] The above-mentioned further technical solution provides guidance for the movement of the treatment chamber through linear guide rails and sliders.

[0014] Furthermore, the treatment chamber is equipped with a Y-axis reciprocating drive mechanism, a Z-axis lifting drive mechanism, an X-axis rotation drive mechanism, and a Z-axis rotation drive mechanism; the Y-axis reciprocating drive mechanism is mounted on the treatment chamber; the Z-axis lifting drive mechanism is mounted on the Y-axis reciprocating drive mechanism, and the Y-axis reciprocating drive mechanism drives the Z-axis lifting drive mechanism to reciprocate along the Y-axis; the Z-axis rotation drive mechanism is mounted on the Z-axis lifting drive mechanism, and the Z-axis lifting drive mechanism drives the Z-axis rotation drive mechanism to move up and down along the Z-axis; the X-axis rotation drive mechanism is mounted on the Z-axis rotation drive mechanism, and the Z-axis rotation drive mechanism drives the X-axis rotation drive mechanism to rotate around the Z-axis; the plasma treatment head is mounted on the X-axis rotation drive mechanism, and the X-axis rotation drive mechanism drives the plasma treatment head to rotate around the X-axis.

[0015] By adopting the above-mentioned further technical solutions, the plasma treatment head can treat patients at different locations and angles through the Y-axis reciprocating drive mechanism, the Z-axis lifting drive mechanism, the X-axis rotation drive mechanism, and the Z-axis rotation drive mechanism.

[0016] Furthermore, the Y-axis reciprocating drive mechanism includes a Y-axis linear guide rail, which is mounted on the treatment chamber. The Z-axis lifting drive mechanism is mounted on the Y-axis linear guide rail. The Z-axis lifting drive mechanism includes a mounting base and a Z-axis lifting drive component. The mounting base is mounted on the Y-axis linear guide rail, the Z-axis lifting drive component is mounted on the mounting base, and the Z-axis rotation drive mechanism is mounted on the Z-axis lifting drive component.

[0017] Furthermore, the treatment chamber is equipped with an exhaust mechanism, which includes an air inlet box, a ventilation box, and an exhaust fan. The air inlet boxes are symmetrically distributed on both sides of the treatment chamber. The ventilation box is connected to the air inlet box. The air inlet box has several air inlets. The upper part of the ventilation box has an air outlet. An exhaust fan is installed on the air outlet. The air inlet is connected to the exhaust fan through a ventilation channel.

[0018] By adopting the above-mentioned further technical solution, the plasma exhaust gas dispersed in the treatment chamber is extracted by the exhaust mechanism and transported to the plasma exhaust gas purification device for internal purification.

[0019] Furthermore, the treatment chamber also includes a baffle and a baffle lifting drive mechanism. The baffle is symmetrically arranged on the front and rear sides of the treatment chamber, and the baffle lifting drive mechanism is installed on the treatment chamber. The baffle lifting drive mechanism drives the baffle to rise or fall.

[0020] By adopting the above-mentioned further technical solution, the baffle lifting drive mechanism provides the power for the baffle to move up and down; the baffle can seal and block the plasma airflow inside the treatment chamber from diffusing out of the chamber, making it convenient to collect plasma exhaust gas.

[0021] The advantages of this invention are: the plasma therapy head of this device can irradiate different parts of the patient from head to toe in different directions without the patient needing to move, and the irradiation range and area are wide, making it particularly suitable for the treatment of critically ill patients; it is stable and reliable, and simple and convenient to operate.

Detailed Implementation

[0042] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0043] It should be noted that the X-axis referred to in this application is a virtual axis parallel to the length direction of the treatment bed 1, the Y-axis referred to in this application is perpendicular to the X-axis, and the Z-axis referred to in this application is perpendicular to the plane formed by the X-axis and the Y-axis; the front-back and left-right directions referred to in this application refer to the front-back direction with the head and foot of the treatment bed as the front-back direction and the left-right direction with the sides of the treatment bed as the left-right direction.

[0044] like Figure 1-15 As shown, a plasma therapy device with a treatment chamber includes a treatment bed 1 and a treatment chamber 2 installed on the treatment bed 1. The treatment chamber 2 can reciprocate along the length of the treatment bed 1, with a movement distance greater than 1 meter. A plasma therapy head 2.13 is provided inside the treatment chamber 1. The plasma therapy head 2.13 can reciprocate along the Y-axis and Z-axis within the treatment chamber 2, and can rotate around the X-axis and Z-axis within the treatment chamber 2.

[0045] The purpose of moving the treatment chamber is to ensure that the patient's head to feet are covered within the irradiation range of the plasma treatment head 2.13 while reducing the size of the equipment, thereby reducing the patient's movement and making it particularly convenient for patients with other auxiliary medical devices to receive treatment.

[0046] See Figure 1-7 The treatment bed 1 includes a bed frame 1.2, a bed board 1.11, a mattress 1.10, and a treatment bed shell 1.1. The bed board 1.11 is installed on the bed frame 1.2, and the mattress 1.10 is placed on the bed board 1.11. The treatment bed shell 1.1 covers the bed frame 1.2. In addition to its aesthetic and tidying function, the treatment bed shell 1.1 also provides protection for the components inside the bed frame 1.2.

[0047] The bed frame 1.2 is equipped with a treatment chamber reciprocating drive mechanism, which includes a drive motor 1.9, a lead screw 1.6, a lead screw nut 1.3, a treatment chamber linear guide rail 1.5, and a slider 1.4. The two ends of the lead screw 1.6 are rotatably mounted on the bed frame 1.2 via bearing seats 1.8. The lead screw nut 1.3 is mounted on the lead screw 1.6. The piston rod of the drive motor 1.9 is connected to the lead screw 1.6 for transmission. The treatment chamber linear guide rail 1.5 is mounted on the bed frame 1.2. The treatment chamber linear guide 1.5 is arranged parallel to the length direction of the treatment bed 1. The slider 1.4 is mounted on the treatment chamber linear guide 1.5. The bottom of the treatment chamber 2 is provided with a base plate 2.18, which is located below the bed board 1.11. The two sides of the treatment bed shell 1.1 are provided with through slots for the base plate 2.18 to pass through. The base plate 2.18 is fixedly connected to the lead screw nut 1.3 by screws. The slider 1.4 is fixedly connected to the base plate 2.18 by screws. The drive motor 1.9 drives the lead screw 1.6 to rotate on the bearing seat 1.8. The rotation of the lead screw 1.6 causes the lead screw nut 1.3 to move linearly on the lead screw 1.6. The lead screw nut 1.3 drives the base plate 2.18 to move, thereby causing the treatment chamber 2 to move along the length direction of the treatment bed 1. The slider 1.4 moves on the treatment chamber linear guide 1.5 to guide the movement of the treatment chamber 2.

[0048] See Figure 3 , 8-15, the treatment chamber 2 includes a treatment chamber shell 2.4 and a treatment chamber frame 2.1. The treatment chamber shell 2.4 is mounted on the treatment chamber frame 2.1. The treatment chamber 2 is equipped with a Y-axis reciprocating drive mechanism 2.7, a Z-axis lifting drive mechanism, an X-axis rotation drive mechanism 2.12, and a Z-axis rotation drive mechanism 2.11. The Y-axis reciprocating drive mechanism 2.7 includes a Y-axis linear guide rail and a Y-axis reciprocating drive motor. The Y-axis linear guide rail is mounted on the treatment chamber 2. The Z-axis lifting drive mechanism includes a mounting base 2.9 and a Z-axis lifting drive component 2.10. The mounting base 2.9 is mounted on the Y-axis linear guide rail, the Z-axis lifting drive component 2.10 is mounted on the mounting base 2.9, and the Z-axis rotation drive mechanism 2.11 is mounted on the Z-axis lifting drive component 2.10. The X-axis rotation drive mechanism 2.12 is mounted on the Z-axis rotation drive mechanism 2.11. The plasma treatment head 2.13 is mounted on the X-axis rotation drive mechanism 2.11.

[0049] The Y-axis reciprocating drive motor drives the mounting base 2.9 to move along the Y-axis linear guide rail, thereby causing the Z-axis lifting drive 2.10, Z-axis rotation drive mechanism 2.11, X-axis rotation drive mechanism 2.12, and plasma treatment head 2.13 to move as a whole along the Y-axis linear guide rail; the Z-axis lifting drive 2.10 drives the Z-axis rotation drive mechanism 2.11 to move up and down along the Z-axis, thereby causing the X-axis rotation drive mechanism 2.12 and plasma treatment head 2.13 to move up and down along the Z-axis. The Z-axis lifting drive 2.10 can be a hydraulic cylinder, pneumatic cylinder, electric telescopic rod, bamboo-joint electric hanger, etc., and the structure of the Z-axis lifting drive 2.10 is not limited in this embodiment; the Z-axis rotation drive mechanism 2.11 drives the X-axis rotation drive mechanism 2.12 and plasma treatment head 2.13 to move up and down along the Z-axis. The Z-axis rotation drive mechanism 2.12 rotates around the Z-axis, thereby driving the plasma treatment head 2.13 to rotate around the Z-axis by 360°. The Z-axis rotation drive mechanism 2.11 can be a rotary motor. The X-axis rotation drive mechanism 2.12 drives the plasma treatment head 2.13 to rotate around the X-axis by 180°. The X-axis rotation drive mechanism 2.12 can also be a rotary motor. The Y-axis reciprocating drive mechanism 2.7, the Z-axis lifting drive mechanism, the X-axis rotation drive mechanism 2.12, and the Z-axis rotation drive mechanism 2.11 enable the plasma treatment head 2.13 to be adjusted in the X-axis, Y-axis, and Z-axis directions as well as at multiple angles. By adjusting the angle and direction of the plasma treatment head 2.13, precise irradiation treatment of various parts of the human body can be achieved.

[0050] The treatment chamber 2 is equipped with an exhaust mechanism, which includes an air inlet box 2.2, a ventilation box 2.2.4, and an exhaust fan 2.8. The air inlet boxes 2.2 are symmetrically distributed on the lower left and right sides of the treatment chamber 2. The ventilation box 2.2.4 is located above the air inlet boxes 2.2 and communicates with them. The air inlet boxes 2.2 and 2.2.4 are connected to form a ventilation channel 2.2.5. The upper part of the ventilation box 2.2.4 is provided with an air outlet 2.2.3. The air inlet box 2.2 has several air inlets 2.2.3. The air inlets 2.2.3 are connected to the air outlets 2.2.3 through the ventilation channel 2.2.5. An exhaust fan 2.8 is installed on the air outlets 2.2.3.

[0051] See Figure 10 , 11 13-15, The treatment chamber 2 is equipped with an exhaust mechanism, symmetrically arranged on both sides of the treatment bed 1. The purpose of the symmetrical arrangement is to ensure the uniformity and symmetry of the air extraction within the treatment chamber 2, preventing the plasma airflow generated by the plasma treatment head 2.13 from deviating and affecting the treatment effect. The purpose of installing the exhaust mechanism is to recover plasma exhaust gas, preventing environmental pollution and harm to the patient.

[0052] The treatment chamber 2 also includes a baffle 2.3 and a baffle lifting drive mechanism 2.6. The baffle 2.3 is symmetrically arranged on the front and rear sides of the treatment chamber 2. The baffle lifting drive mechanism 2.6 is installed on the treatment chamber 2 and drives the baffle 2.3 to rise or fall. The baffle lifting drive mechanism 2.6 includes a drive assembly and a lifting assembly. The drive assembly includes a motor and a drive gear installed at the output end of the motor. The lifting assembly includes a connecting rod one and a connecting rod two hinged to each other. One end of the connecting rod one is slidably installed on the top of the treatment chamber 2. The first connecting rod is slidably mounted on the baffle 2.3 at one end, and the second connecting rod is slidably mounted on the top of the treatment chamber 2 at one end. The second connecting rod is provided with a driven gear that meshes with the driving gear. The treatment chamber 2 is provided with a slide rail for the first and second connecting rods to slide on, and the baffle 2.3 is provided with a slide rail for the first connecting rod to slide on. The treatment chamber 2 is symmetrically provided with baffle guide rails 2.5, and the two sides of the baffle 2.3 are slidably mounted on the baffle guide rails 2.5, which guide the movement of the baffle 2.3.

[0053] The treatment chamber 2 is equipped with baffles 2.3 on both the front and rear sides. Driven by the baffle lifting drive mechanism 2.6, the baffles 2.3 move up and down along the baffle guide rail 2.5. The lifting height of the baffles 2.3 can be controlled according to the size of the patient's body to form a relatively sealed space inside the treatment chamber, preventing the plasma exhaust gas from diffusing outward. At the same time, the plasma gas flow can stay inside the treatment chamber 2, allowing the plasma gas inside the treatment chamber 2 to surround the surface of the human skin. The patient's skin inside the treatment chamber 2 is exposed. In this way, the plasma generated by the plasma treatment head 2.13 can not only act on the irradiation position, but also act on all the exposed skin of the patient inside the treatment chamber 2, achieving the effect of plasma bathing and improving the treatment effect.

[0054] The treatment bed 1 is equipped with support casters 1.7 at the bottom to facilitate the movement of the treatment bed 1.

[0055] The treatment chamber 2 is equipped with a power module 2.14 and a control module 2.15. The control module 2.15 is electrically connected to the power module 2.14, the drive motor 1.9, the baffle lifting drive mechanism 2.6, the Y-axis reciprocating drive mechanism 2.7, the exhaust fan 2.8, the Z-axis lifting drive component 2.10, the Z-axis rotation drive mechanism 2.11, and the X2-axis rotation drive mechanism 2.12. The power module 2.14 is electrically connected to the plasma treatment head 2.13. The treatment chamber shell 2.4 is equipped with an observation window 2.16 and a control panel 2.17. The observation window 2.16 is used to facilitate the operator's observation of the precise treatment position of the patient inside the treatment chamber 2. The control panel 2.17 is used to facilitate the operator's operation and control of the equipment.

[0056] In the above embodiments, the materials of the treatment bed shell 2.4 and the treatment chamber shell 1.1 are both insulating materials, which serve to insulate the electrical components from the patient, and also for aesthetic purposes and ease of processing.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
