Description

Technical Field

[0001] The present invention relates to the field of skin lesion treatment, in particular to a plasma therapeutic apparatus for skin and mucous membrane damage. Background Art

[0002] Plasma mainly destroys the protein integrity of bacteria, thereby changing the bacterial metabolism and ultimately inactivating them. Further studies have found that low-temperature plasma can be used for sterilization of skin and other tissues. That is, plasma is generated in its cavity through indirect plasma and sprayed onto the skin in the form of airflow. It can not only reduce the impact of high-frequency current itself on the skin, but also directly achieve anti-inflammatory, antipruritic, antibacterial, tissue stimulation, microcirculation stimulation and other therapeutic effects through the combined effects of ultraviolet radiation, reactive oxygen species, reactive nitrogen and electric fields.

[0003] Based on the above technology, patent application number CN201020670502.2 provides a plasma skin and mucosal disease therapeutic device, whose technical solution includes a main control unit, a driving power supply, a micro air pump, a plasma generating unit and a treatment head. The plasma generating unit is provided with an air outlet and an air inlet. The main control unit is connected to the driving power supply and the micro air pump respectively, the driving power supply is connected to the plasma generating unit, the air pump is connected to the air inlet of the plasma generating unit, and the treatment head is connected to the air outlet of the plasma generating unit.

[0004] The above patent relies on airflow to treat the mucosa by directing plasma to the damaged area of ​​the mucosa. However, based on actual conditions, the skin and mucosa are located in different locations. That is, for the treatment of the skin and mucosa in the oral cavity, the above patent application has significant limitations. For example, during oral treatment, the patient's mouth is in an open state. In this state, it is difficult for the patient to swallow. The problem that comes with this is that the amount of saliva in the patient's mouth surges, and comfort decreases. In addition, the rising saliva tends to cover the damaged area of ​​the mucosa, which greatly interferes with the treatment effect. Secondly, the angle of the airflow into the oral cavity is difficult to adjust based on the patient's subjective factors. That is, it is impossible to achieve a dead-angle spraying effect by simply adjusting the angle of the spray body. Therefore, based on the current actual situation, there is an urgent need for a plasma therapy device specifically for treating the oral mucosa. Summary of the Invention

[0005] The purpose of the present invention is to provide a plasma therapy device for damaged skin and mucous membranes to solve the limitations of patent application number CN201020670502.2 in the treatment of oral skin and mucous membranes. For example, during oral treatment, the patient's mouth is in an open state. In this state, it is difficult for the patient to swallow. The resulting problem is that the amount of saliva in the patient's mouth increases sharply, and comfort decreases. In addition, the continuously increasing saliva tends to cover the damaged mucous membranes, which greatly interferes with the treatment effect. Secondly, the angle of the airflow to the oral cavity is difficult to adjust based on the patient's subjective factors. That is, the technical problem of achieving a dead-angle-free spraying effect cannot be achieved by simply adjusting the angle of the spray body.

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative work are all within the scope of protection of the present invention.

[0046] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0047] Example 1

[0048] In this embodiment, a plasma treatment device for damaged skin and mucous membranes is provided, comprising an air pump 1, a plasma generator 2 arranged at the air pump 1 and combined with the air pump 1, and a treatment body 3 separate from the combined body;

[0049] The treatment body 3 includes a handle body 32 inserted into the patient's mouth, and a treatment tube, a drainage tube 37 and a saliva absorption tube separately arranged in the handle body 32;

[0050] The treatment tube is connected to the catheter 4 and is provided with a slot for directing airflow into the oral cavity;

[0051] The drainage tube 37 is rotatably arranged in the handle body 32, wherein one end of the drainage tube 37 is located in the patient's oral cavity, and the other end of the drainage tube 37 is located outside the oral cavity;

[0052] One end of the drainage tube 37 located in the patient's mouth directly points to the drainage port of the treatment tube;

[0053] The saliva absorption tube extends outward in both directions relative to the handle body 32. The extended end of one of the saliva absorption tubes contacts the lowest point in the oral cavity, and the extended end of the other saliva absorption tube is connected to the end of the drainage tube 37 located outside the oral cavity. After the drainage tube 37 is inserted into the treatment tube, the saliva absorption tube absorbs and drains the saliva by blocking the groove.

[0054] See also Figure 1-3In this example, a plasma therapy device for treating oral mucosa is proposed. The therapy device combines an air pump 1, a plasma generator 2, a handle body 32, a treatment tube, a discharge pipe 37, a saliva absorption tube, and a catheter 4. The purpose is to guide the plasma produced in the plasma generator 2 by the air pump 1 to perform extensive sterilization treatment on the oral mucosa. During the treatment, without removing the handle body 32, the discharge pipe 37 and the treatment tube cooperate with each other (the patient actively blocks the slot), and then, under the principle of negative pressure, the saliva in the oral cavity is adsorbed and discharged.

[0055] The following is a detailed description of the saliva discharge function involved in this example in combination with the specific structure:

[0056] Saliva drainage involves components such as treatment tubing, drainage tube 37 and saliva absorption tubing;

[0057] The specific configurations of the above components are described below:

[0058] ① The discharge pipe 37 includes a coil 371 rotatably arranged in the handle body 32 and a permeation tube 372 installed at one end of the coil 371; a T-shaped insert 373 is installed at the end of the permeation tube 372 away from the coil 371; after the permeation tube 372 and the T-shaped insert 373 are fully inserted into the valve tube 35, the air flow in the guide tube 33 is discharged only from the coil 371 by blocking the slot.

[0059] ② The treatment tube includes an angle adjustment unit 34, a flow guide tube 33 and a valve tube 35 provided at both ends of the angle adjustment unit 34, wherein the flow guide tube 33 is installed at the handle body 32 and communicates with the catheter 4;

[0060] The valve tube 35 includes a sleeve 352 installed at the outlet of the angle adjustment unit 34 and a rubber plug 351 embedded in the sleeve 352. A channel is provided in the rubber plug 351. After the T-shaped insert 373 is fully inserted into the channel, the permeation tube 372 is fully extended into the sleeve 352, and the outer wall of the permeation tube 372 is in close contact with the inner wall of the sleeve 352.

[0061] ③ The saliva absorption tube includes a straw 38 mounted on the handle body 32. The straw 38 is a flexible tube, and both ends of the straw 38 extend outward from the handle body 32. A saliva suction tip 36 is mounted on one of the extended ends of the straw 38. The saliva suction tip 36 is located at the lowest point of the patient's mouth.

[0062] In addition, the straw 38 is provided with an inclined opening at another extension portion of the handle body 32. For this purpose, the negative pressure tube 31 is installed in the inclined opening, and the other end of the negative pressure tube 31 is rotated and arranged at the end of the spiral tube 371 located outside the oral cavity.

[0063] Combining the above components, the principle of saliva discharge is explained:

[0064] See also Figure 1-9 The handle body 32 is inserted into the patient's mouth. During treatment, the patient's mouth and the external environment are kept in a closed state as much as possible (in a closed state, the interference of external airflow can be significantly reduced, thereby improving the therapeutic effect of plasma). The plasma is guided into the guide tube 33 through the catheter 4, and then the plasma overflows outward from the angle adjustment unit 34, filling the patient's mouth. In addition, in order to maintain the internal and external pressure difference of the patient's mouth, the plasma is guided outward through the permeation tube 372 installed at the spiral tube 371 to ensure that the plasma continuously contacts the damaged mucosa in the oral cavity in a flowing state, thereby improving the therapeutic effect.

[0065] If the patient keeps the handle body 32 fixed for a long time, the effectiveness of the swallowing action will be significantly reduced. Therefore, during treatment, the cleaning of saliva in the patient's mouth is an important factor affecting the patient's experience. Therefore, without removing the handle body 32, by screwing the screw tube 371, the infiltration tube 372 and the T-shaped insert 373 installed at one end of the screw tube 371 can be completely inserted into the valve tube 35, that is, the rubber stopper 351 is pierced through the T-shaped insert 373 to connect the screw tube 371 with the angle adjustment unit 34, so as to block the angle adjustment unit 34 on the patient's tongue, so that the airflow in the guide tube 33 is discharged only from the screw tube 371 (the infiltration tube 372 also has the effect of discharging airflow, but considering that the patient keeps the handle body 32 fixed for a long time, the sealing effect inside and outside the patient's mouth is not firm, so the airflow rate in the screw tube 371 is not sufficient to generate a high-quality negative pressure). Subsequently, the saliva in the mouth is absorbed and discharged through the cooperation of the suction tube 38 and the screw tube 371.

[0066] In combination with the above, in this embodiment, the drain pipe 37 not only has a draining function, but also has a control function.

[0067] Of course, the premise of the above use effect is that the handle body 32 is always inserted in the patient's mouth.

[0068] Example 2

[0069] In this embodiment, a plasma treatment device for damaged skin and mucous membranes is provided, comprising an air pump 1, a plasma generator 2 arranged at the air pump 1 and combined with the air pump 1, and a treatment body 3 separate from the combined body;

[0070] The treatment body 3 includes a handle body 32 inserted into the patient's mouth, and a treatment tube, a drainage tube 37 and a saliva absorption tube separately arranged in the handle body 32;

[0071] The treatment tube includes an angle adjustment unit 34, a flow guide tube 33 and a valve tube 35 provided at both ends of the angle adjustment unit 34. It should be noted that the flow guide tube 33 is installed on the handle body 32 and is connected to the catheter 4;

[0072] The angle adjustment unit 34 includes a curved pipe 341 and a slot 342 arranged at the curved pipe 341;

[0073] A sealing curved plate 344 is provided in the curved pipe 341 and has the same curvature as the curved pipe 341;

[0074] The sealing bent plate 344 completely blocks the slot 342;

[0075] A limiting pipe head 343 is slidably installed at the slot 342 . The limiting pipe head 343 is connected to the sealing bent plate 344 , and a treatment channel is provided in the limiting pipe head 343 that is connected to the inner lumen of the bent pipe 341 .

[0076] It should be noted that the position limiting tube head 343 is the component that contacts the patient's tongue.

[0077] See also Figure 1-5 Considering the limitation of adjusting the blowing direction only by the position of the swing handle body 32, an angle adjustment unit 34 is provided at the guide tube 33. The angle adjustment unit 34 can not only adjust the airflow ejection angle, but also is an important combined structure for guiding the discharge of saliva.

[0078] To adjust the airflow spray angle, the patient's tongue is simply contacted with the limiting tube head 343, and force is applied to the limiting tube head 343 to control the spray angle when the limiting tube head 343 changes position relative to the slot 342.

[0079] For guiding saliva discharge, the patient's tongue contacts the limiting tube head 343 , and by blocking the limiting tube head 343 , the airflow discharged from the limiting tube head 343 is restricted, so that the airflow of the guide tube 33 is discharged only from the spiral tube 371 .

[0080] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
