Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a multifunctional negative pressure moxibustion device and a control method thereof. Background Art

[0002] There are three main types of Chinese medicine treatments, namely acupuncture, massage and cupping, which are accepted by the majority of patients due to their simple treatment methods, rapid effects, no pain and no side effects. They are now widely used in internal medicine, surgery, pediatrics, gynecology and neurology, especially for rheumatism, senile bone and muscle diseases, and stubborn headaches. The effects are particularly significant, so people often say "acupuncture, cupping, half of the disease is cured."

[0003] With the rapid development of modern science and technology, various new acupuncture medical devices are constantly being produced. For example, acoustic electroacupuncture, electric heating needle, laser needle, microwave needle, ultrasonic acupuncture, etc. These acupuncture electronic products are derived from the concept of single acupoint acupuncture treatment. Single stimulation only acts on individual acupoints, rather than starting from the overall concept of traditional Chinese medicine, so it is difficult to play a therapeutic role in adjusting the meridians.

[0004] Of course, nowadays, there are negative pressure cupping products similar to Chinese medicine fire cupping, which form negative pressure to absorb on the acupuncture points of the skin, increase blood microcirculation to achieve more significant health care effects than conventional mechanical negative pressure moxibustion devices. On the one hand, most of the existing negative pressure cupping products use external vacuum pumps to generate negative pressure, which is inconvenient to use and easy to lose, resulting in the inability to use the negative pressure moxibustion device normally. On the other hand, the existing negative pressure cupping only focuses on how to form negative pressure without burning heated air in the cup body, and is not based on the overall concept of Chinese medicine, so it is difficult to play a therapeutic role in adjusting the meridians. Summary of the invention

[0017] Preferably, the massage stick is connected to the power supply via a second heating switch.

[0018] Preferably, an acupoint-finding key is provided on the housing, and an acupoint detection circuit for cooperating with the acupoint-finding key to determine the acupoints of the body is provided on the control circuit board.

[0022] After the functional sheet is sleeved on the lower end of the massage stick and the negative pressure moxibustion device is placed on the skin as needed, the control circuit board controls the air pump to start so that the negative pressure moxibustion device is automatically adsorbed on the skin so that the functional sheet is attached to the skin, and the lower end of the massage stick is pressed on the skin to stretch the skin so that the distance between the meridians under the skin and the surface of the skin becomes smaller;

The lower end of the massage stick is pressed on the skin to stretch the skin and reduce the distance between the meridians under the skin and the skin surface, which is conducive to improving the pressing effect of the massage stick on the meridians and the cupping effect of the negative pressure on the meridians, and is also conducive to the penetration of the functional materials on the functional sheet into the skin. Therefore, the present invention starts from the overall concept of traditional Chinese medicine, combines traditional acupuncture and cupping into one, and compared with the combination of acupuncture and cupping in traditional Chinese medicine, the negative pressure moxibustion tool of the present invention stretches the skin, reduces the distance between the meridians under the skin and the skin surface, so as to achieve a better use effect. In addition, the present invention also has the advantages of simple structure and convenient operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0032] Combination Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a multifunctional negative pressure moxibustion tool (hereinafter referred to as "moxibustion tool" or "negative pressure moxibustion tool"), comprising: a shell formed by connecting an upper shell 11 and a lower shell 12, and the lower shell 12 is provided with an air intake hole 13 and an air exhaust hole 14; a first adsorption ring 21 arranged on the lower side of the lower shell 12, the first adsorption ring 21 and the lower side of the lower shell 12 together form a moxibustion cavity with an opening facing downward, and the air intake hole 13 is located in the moxibustion cavity and the air exhaust hole 14 is located on the outside of the first adsorption ring 21; a moxibustion cavity with an upper end fixed on the lower shell 12 and a lower end extending to the moxibustion cavity The massage stick 3, the height H2 of the lower end of the massage stick 3 extending out of the lower end surface of the first adsorption circle 21 is 0.2-4cm, and the lower end of the massage stick 3 is set to a spherical surface to improve the comfort of contact with the skin; a power supply 4 (generally a battery, of course, an external power supply can also be used), an air pump 5 and a control circuit board 6 are arranged in the shell, the power supply 4 is electrically connected to the air pump 5 through the control circuit board 6, and the suction end and the exhaust end of the air pump 5 are respectively connected to the suction hole 13 and the exhaust hole 14; a heating source for heating the moxibustion cavity, the heating source is electrically connected to the power supply 4.

[0033] The first adsorption circle 21 is placed on the skin, and the skin closes the lower opening of the moxibustion cavity. The air pump 5 is started to continuously extract air from the moxibustion cavity to generate negative pressure in the moxibustion cavity, so that the negative pressure moxibustion tool is adsorbed on the skin through the first adsorption circle 21, and the lower end of the massage stick 3 is in contact with the skin. At the same time, the heating source generates heat to increase the temperature in the moxibustion cavity, thereby improving the use environment of warm moxibustion for the skin.

[0034] Generally speaking, the first adsorption circle 21 is in any shape such as round, oval or square, and the height H1 of the first adsorption circle 21 (ie, the height of the first adsorption circle 21 extending downward from the lower side of the lower shell 12) is generally preferably 1-3 cm.

[0035] The present invention sets the lower end of the massage stick 3 to extend out of the lower end surface of the first adsorption circle 21, and sets the height H2 between the lower end of the massage stick 3 and the lower end surface of the first adsorption circle 21 to be 0.5-4 cm, that is, the height of the massage stick 3 is 0.5-4 cm longer than the height H1 of the first adsorption circle 21. In addition, the massage stick 3 is preferably located in the center of the moxibustion cavity. The structural setting of the massage stick 3 of the present invention is based on the overall concept of traditional Chinese medicine, combining traditional acupuncture and cupping into one. Compared with the combination of acupuncture and cupping in traditional Chinese medicine, the negative pressure moxibustion device of the present invention can achieve better use effects.

[0036] In a preferred embodiment, the massage stick 3 has a length-adjustable structure, and the length of the lower end of the massage stick 3 extending out of the lower end surface of the first adsorption circle 21 can be adjusted by the length-adjustable structure to meet the actual needs of the massage stick 3 for different massage strengths required for different parts of the body or the massage strength required by different users. For example, the length-adjustable structure includes a thread provided at the upper end of the massage stick 3, and the upper end of the massage stick 3 is screwed to the lower shell 12 through the thread. By adjusting the tightness of the screwing of the massage stick 3 relative to the lower shell 12, the actual length of the massage stick 3 exposed outside the lower shell 12 can be changed. For another example, the length-adjustable structure is a segmented stretching structure or a snap-on stretching structure.

[0037] Combine the following Figure 2 A typical usage scenario of the negative pressure moxibustion device of the present invention is taken as an example for further explanation.

[0038] First, a functional sheet 9 with a certain function (such as a mugwort sheet, a ginger sheet, a plaster or a medicine coated on a functional sheet) is sleeved on the lower end of the massage stick 3 .

[0039] Secondly, the negative pressure moxibustion device is placed at a certain position of the skin as required (generally preferably at the meridians or acupoints of the skin to exert the therapeutic effect of adjusting the meridians), the lower end of the massage stick 3 is pressed on the skin and the lower end surface of the first adsorption circle 21 is in contact with the skin.

[0040] Again, the control circuit board 6 controls the air pump 5 to start, so that the air pump 5 extracts part of the air in the moxibustion cavity, thereby forming a negative pressure in the moxibustion cavity so that the negative pressure moxibustion tool is automatically adsorbed on the skin, and the functional sheet 9 is attached to the skin. On the one hand, since the height H2 between the lower end of the massage stick 3 and the lower end surface of the first adsorption circle 21 is 0.2-4cm, the lower end of the massage stick 3 is pressed on the skin and the skin at the pressing position is concave, so the present invention uses the massage stick 3 to perform local pressing on the skin to replace the traditional puncture type acupuncture; on the other hand, due to the negative pressure in the moxibustion cavity, part of the skin surface will be convex and sucked into the moxibustion cavity, so that the skin and the functional sheet 9 fit together. At the same time, because the massage stick 3 is pressed on the skin, it objectively stretches the skin to avoid the skin surface being excessively sucked into the moxibustion cavity without hindrance, which causes the distance between the skin surface at the negative pressure adsorption position of the moxibustion tool and the meridians under the skin to increase, resulting in the efficiency of cupping and the defects of the functional components in the functional sheet 9 being difficult to penetrate into the meridians. For example, at a certain position of a person's body, the meridian is located 5 thickness units below the skin epidermis. When using traditional cupping, part of the skin surface is sucked into the negative pressure chamber of the cupping, causing accumulation of the skin surface at the cupping adsorption position, causing the meridian at the adsorption position to increase to 8-10 thickness units away from the skin epidermis, which is obviously not conducive to cupping therapy for the meridians. The present invention sets a massage rod 3 to press on the skin, and the skin around the massage rod 3 is pressed downward by the lower end of the massage rod 3 to stretch, and the skin at the pressing position is sucked into the moxibustion cavity from all sides under the action of negative pressure, resulting in the meridians at the pressing position of the massage rod 3 being reduced to 2-3 thickness units away from the skin epidermis, and only the meridians near the first adsorption circle 21 are slightly increased to 6-7 thickness units away from the skin epidermis, thereby avoiding the accumulation of the skin surface in the moxibustion cavity. Not only can the massage rod 3 act more directly on the meridians under the skin, but also because the skin is moderately stretched by the massage rod 3, it is more conducive to cupping therapy on the meridians under the skin at the adsorption position using the negative pressure in the moxibustion cavity, and the functional sheet 9 cannot be attached to the skin by other material attachment measures such as bonding and can be attached to the skin and closer to the meridians under the skin, so that it is more conducive to penetrating into the skin to adjust the meridians.

[0041] Finally, the heating source is controlled to start working to heat the moxibustion cavity, which accelerates the blood microcirculation in the skin and promotes the functional materials in the functional sheet 9 to penetrate into the skin faster, thereby achieving a better use effect.

[0042] It can be seen that the negative pressure moxibustion device proposed by the present invention combines traditional acupuncture and cupping into one. Compared with the combination of acupuncture and cupping in traditional Chinese medicine, the negative pressure moxibustion device of the present invention can achieve better use effect. In addition, the negative pressure moxibustion device proposed by the present invention has multiple uses. In addition to the above description of using the moxibustion cavity to promote the better penetration of the functional materials in the functional sheet 9 into the skin during physical therapy, of course, the negative pressure moxibustion device of the present invention can also be used without the functional sheet 9 for people's daily massage therapy.

[0043] According to traditional Chinese medicine therapy, when the negative pressure moxibustion device is used on acupuncture points where meridians are concentrated or intersecting, better use effects can be achieved. However, acupuncture points are probabilities in traditional Chinese medicine. Although professionals in traditional Chinese medicine know very well which part of the body is an acupuncture point, it is difficult for ordinary users to determine which part of their body is an acupuncture point. In order to facilitate users to use the negative pressure moxibustion device of the present invention to adjust the meridians, especially the acupuncture points for therapy, the negative pressure moxibustion device of the present invention provides a function of determining the meridian acupuncture points for user reference. The present invention is provided with an acupuncture point search key 8 on the shell, and an acupuncture point detection circuit for cooperating with the acupuncture point search key 8 to determine the body acupuncture points is provided on the control circuit board 6.

[0044] Specifically, the acupoint detection circuit includes a controller (such as a single-chip microcomputer) arranged on a control circuit board 6, a signal source for generating an acupoint-seeking signal (for example, if the signal source is a voltage source, the acupoint-seeking signal is a voltage signal of a preset size; for example, if the signal source is a current source, the acupoint-seeking signal is a current signal of a preset size), and an acupoint-seeking key 8 is provided on the shell 1, and the surface of the acupoint-seeking key 8 also has a conductive layer. The acupoint-seeking key 8 is a normally open switch, wherein the signal source is connected to the massage stick 3 through the acupoint-seeking key 8, and the acupoint-seeking key 8 is electrically connected to one of the data ports of the controller. When using the negative pressure moxibustion device to find the acupuncture points on the body, hold the negative pressure moxibustion device and press the acupuncture point search key 8 so that the acupuncture point search key 8 switches to the on state. At this time, the acupuncture point search signal (a current signal or a voltage signal of a preset size) generated by the signal source passes through the massage stick 3, the body skin to the fingers, and the acupuncture point search key 8 to form a loop. Therefore, when the massage stick 3 contacts the body skin at different positions, the resistance between the contact position of the massage stick 3 with the body skin and the fingers will change, especially when the massage stick 3 moves to the acupuncture points on the body skin. Since the acupuncture points are actually concentrated areas of the meridians, the resistance will be significantly reduced. At this time, the detection result on the acupuncture point search key 8 sensed by the data port of the controller (the detection result corresponds to the detection voltage or detection current) will also be significantly reduced. Therefore, when designing the negative pressure moxibustion device, it is only necessary to conduct detection tests at various acupuncture points on the body in advance according to the output current size of the selected signal source or the output voltage size of the voltage source, and pre-determine the preset threshold value (the preset threshold value refers to the preset voltage threshold value or the preset current threshold value) according to the change of the detection voltage or detection current sensed by the data port of the controller in the test. When the change of the detection voltage sensed by the data port of the controller exceeds the preset voltage threshold value or the change of the sensed detection current exceeds the preset current threshold value, it is considered that the position where the massage stick 3 contacts the skin is an acupuncture point on the body.

[0045] Furthermore, the control circuit board is also provided with a reminder module for emitting flashing light or / and sound prompts, such as a speaker or an LED light, and the reminder module is electrically connected to a control port of the controller. When the negative pressure moxibustion tool is in the acupuncture point search working mode, when the controller determines that the massage stick 3 is in contact with the skin at an acupuncture point of the body, the reminder module will emit flashing light or / and sound prompts to remind the user that the massage stick 3 is in contact with the skin at this time. At this time, if the user's finger releases the acupuncture point search key 8 to switch the acupuncture point search key 8 back to the disconnected state, the controller sends a control signal to start the air pump 5 so that the negative pressure moxibustion tool is adsorbed on the acupuncture point of the body, and the massage stick 3 is used to adjust the acupuncture point for physical therapy.

[0046] Therefore, in actual use, the acupoints can be first determined by the acupoint search key 8, and then the negative pressure moxibustion device can be used to adjust the physical therapy at the acupoint position, which can achieve better use effects.

[0047] Among them, there are many implementation methods of the heating source. Generally speaking, the heating source is an electric heating wire or an electric heating film. In one embodiment, the heating source is a graphene heating film 8 arranged on the inner side of the lower shell 12, and the graphene heating film 8 is connected to the power supply 4 through a first heating switch, and the first heating switch is generally arranged on the upper shell 11. When the graphene heating film 8 is powered on, heat is generated, and the heat is conducted to the lower shell 12 and radiated to the skin in the moxibustion cavity, which has massage therapy functions such as improving the micro-blood circulation of the skin. Or / and, the heating source also includes: the massage stick 3 is also connected to the power supply 4 through a second heating switch. When the massage stick 3 is powered on through the second heating switch, the massage stick 3 generates heat using its own impedance, and the heat directly passes through the massage stick 3 to provide a more direct and effective heating therapy to the skin to further improve the massage effect.

[0048] In addition, a pulse current generating module powered by a power supply may be provided in the housing, and the first output end of the pulse current generating module is electrically connected to the massage stick 3, and the second output end of the pulse current generating module is electrically connected to the conductive part provided on the first adsorption circle 21. The pulse current (commonly known as microcurrent in the art) generated by the pulse current generating module is transmitted to the skin through the massage stick 3 to provide massage from the skin, and the pulse current is connected to the loop of the pulse current through the conductive part provided on the first adsorption circle 21. In one embodiment, the first adsorption circle 21 and the conductive part are both made of conductive silicone or conductive rubber, which is conducive to reducing the number of components and simplifying the overall structure. At this time, the second output end of the pulse current generating module is directly electrically connected to the first adsorption circle 21 made of conductive silicone or conductive rubber. Therefore, the pulse current generating module forms an electrical loop of the pulse current through the acupuncture-type conductor, the skin, and the first adsorption circle 21 in sequence. By allowing the massage stick 3 to generate a pulse current directly to the meridians under the skin during use, the massage stick 3 becomes an electric needle to replace the traditional acupuncture function.

[0049] It is common knowledge in the art that the control circuit board 6 controls the operation of the air pump 5 , and the pulse current generating module used can be any model available in the current market.

[0050] Combination Figure 4 and Figure 5 Another embodiment shown. In this embodiment, a second adsorption ring 22 located inside the first adsorption ring 21 is provided on the lower side of the lower shell 12, and the moxibustion cavity is divided into a moxibustion inner cavity located inside the second adsorption ring 22 and a moxibustion outer cavity located between the first adsorption ring 21 and the second adsorption ring 22 by the second adsorption ring 22, and the air suction hole 13 is provided in the moxibustion outer cavity and / or the moxibustion inner cavity. This embodiment provides a solution for providing diversified functions for the negative pressure moxibustion tool by adding the second adsorption ring 22.

[0051] In a preferred embodiment, the air suction hole 13 is only provided in the moxibustion outer cavity, and the functional sheet 9 is sleeved on the lower end of the massage stick 3 and located in the moxibustion inner cavity. Therefore, when the negative pressure moxibustion device is attached to the skin, after starting the air pump 5, only the moxibustion outer cavity is evacuated to form a negative pressure in the moxibustion outer cavity, which eventually causes the entire negative pressure moxibustion device to be adsorbed on the skin. At this time, the moxibustion outer cavity provides the skin with a negative pressure adsorption therapy similar to the existing cupping, while the moxibustion inner cavity is at normal pressure. Since the negative pressure in the moxibustion outer cavity will suck part of the skin into the moxibustion outer cavity, it can objectively cause the skin area covered by the moxibustion inner cavity to be stretched or even tightened, reducing the distance between the meridians under the skin and the surface of the skin. This can not only make the functional sheet 9 fit better on the skin, but also enable the functional materials of the functional sheet 9 to be quickly absorbed by the meridians under the skin to improve the overall use effect.

[0052] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
