Description

Technical Field

[0001] This application relates to the field of medical auxiliary devices, and particularly to a negative pressure type vagus nerve stimulation device. Background Art

[0002] The vagus nerve is a mixed nerve. Its motor fibers originate from the nucleus ambiguus, run parallel to the glossopharyngeal nerve, pass through the brainstem and exit the cranial cavity through the jugular foramen, and supply all the muscles of the pharynx, larynx, and soft palate except the palatopharyngeus and stylopharyngeus muscles. The sensory neurons are located in the jugular ganglion and nodose ganglion near the jugular foramen. The peripheral branches of the jugular ganglion conduct general sensations of a part of the external auditory canal, tympanic membrane, and auricle; the central branches enter the brainstem spinal nucleus of the trigeminal nerve. The peripheral branches of the nodose ganglion conduct sensations of the pharynx, larynx, trachea, esophagus, and various internal organs, and the taste of parts such as the pharynx, soft palate, hard palate, and epiglottis; the central branches enter the solitary tract nucleus. The parasympathetic nerve originates from the dorsal nucleus of the vagus nerve at the bottom of the fourth ventricle and is distributed to internal organs.

[0003] In the chest, the courses and positions of the left and right vagus nerves are different. The left vagus nerve descends between the left common carotid artery and the left subclavian artery to the front of the aortic arch, passes behind the left lung root, gives off several small branches to join the left pulmonary plexus respectively, then disperses into several fine branches in front of the esophagus to participate in the formation of the anterior esophageal plexus, and continues downward to form the anterior vagal trunk. The right vagus nerve passes in front of the right subclavian artery, descends along the right side of the trachea, then gives off several branches behind the right lung root to participate in the right pulmonary plexus, and then gives off branches to form the posterior esophageal plexus behind the esophagus, and synthesizes the posterior vagal trunk at the lower end of the esophagus.

[0004] Clinically, some patients have paroxysmal supraventricular tachycardia. When paroxysmal supraventricular tachycardia occurs, patients will experience palpitation and dizziness discomfort. For this situation, it can be detected after an electrocardiogram examination of the patient. The prior art uses the method of manually stimulating the vagus nerve to relieve the attack of paroxysmal supraventricular tachycardia. For example, pressing the eyeball or using the finger to pick the throat to cause a cough reflex or vomiting can both prevent the attack of paroxysmal supraventricular tachycardia. When necessary, carotid sinus compression can be performed under the guidance of a doctor. This situation can also stimulate the vagus nerve and can also prevent paroxysmal supraventricular tachycardia. However, the manual stimulation of the vagus nerve has poor timeliness and cannot stimulate the vagus nerve in time when paroxysmal supraventricular tachycardia is detected by electrocardiogram; moreover, the manual stimulation method depends too much on the doctor's experience, is unstable, and is not suitable for general application. Summary of the Invention

[0044] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0045] The embodiments of the present application provide a negative pressure type vagus nerve stimulation device, which can solve the problems in the related art that the method of artificially stimulating the vagus nerve depends too much on the level of the doctor's experience, is unstable, and is not suitable for widespread application.

[0046] Refer to Figure 1 , a negative pressure type vagus nerve stimulation device, which includes:

[0047] An outer housing 1, the bottom end of which is provided with a contact opening 10;

[0048] A negative pressure assembly 2, which is connected to the outer housing 1 to form a negative pressure environment inside the outer housing 1;

[0049] A massage structure 3, which is movably arranged inside the outer housing 1, and the bottom end of which is used to contact the human skin sucked into the outer housing 1 and lift and lower together.

[0050] Among them, the outer housing 1 is selected as a cylindrical barrel structure in this embodiment. It is hollow inside, sealed at the top, and the contact opening 10 is provided at its bottom end; the negative pressure assembly 2 includes a negative pressure pipe 20 provided on one side outside the outer housing 1 and a negative pressure device 21 installed inside the negative pressure pipe 20. The negative pressure device 21 can be a vacuum machine or a negative pressure fan, etc. The negative pressure pipe 20 is communicated with the inside of the outer housing 1 so that the negative pressure device 21 can act on the internal environment of the outer housing 1.

[0051] With such a setting, since the contact opening 10 at the bottom end of the outer housing 1 can be covered on the area of the human skin to be stimulated, and the negative pressure assembly 2 is used to form a negative pressure environment inside the outer housing 1. At this time, the covered human skin will be adsorbed into the outer housing 1, and then will come into contact with the massage structure 3 inside the outer housing 1, and will drive the massage structure 3 to rise or fall together during its rising or falling process. During this process, the human skin in this area will be massaged by the massage structure 3, and the vagus nerve inside it will be effectively stimulated. Therefore, when the negative pressure environment formed by the negative pressure assembly 2 inside the outer housing 1 is set, the deformation degree of the human skin and the obtained massage frequency will be stably controlled, which is suitable for general application.

[0052] Optionally, referring to Figure 2 , an inner container 4, which is arranged inside the outer housing 1 and above the massage structure 3, is hollow inside and has a diversion hole 40 opened at its bottom end.

[0053] Among them, the inner container 4 is hollow inside and forms a closed space. The inner container 4 is fixed inside the housing. The inner container 4 contains essential oil, and the diversion hole 40 opened at the lower end of the inner container 4 will allow the essential oil to flow to the massage structure 3 below the inner container 4.

[0054] In addition, the essential oil contained in the inner container 4 refers to a product of volatile substances extracted from spice plants or perfume-producing animals. The essential oil in this device is a product of fragrant substances extracted from spice plants by steam distillation, pressing, cold grinding, or dry distillation methods. These products are in a liquid state at room temperature. The essential oil has direct effects of sterilization, deodorization, and sedation on the skin; indirectly, it has the effects of strengthening the immune function of the respiratory tract, sweating or antipyretic on the respiratory system; it can also play a role in soothing muscle tissues. It can relax the patient's muscles, stabilize the mood, improve the patient's physical function, reduce external pollution such as equipment and labor during stimulation, and contribute to the excitement of the vagus nerve.

[0055] With such a setting, when the vagus nerve of the chest is massaged and stimulated through this device, the essential oil in the inner container 4 can flow to the human skin for auxiliary stimulation, thereby providing the massage stimulation effect of the vagus nerve.

[0056] Optionally, referring to Figure 1 , the massage structure 3 includes:

[0057] The connecting rod 30, the top end of which slides through the diversion hole 40 into the inner container 4;

[0058] The mounting plate 31, which is fixed to the bottom end of the connecting rod 30;

[0059] The massage part 32, which is fixed to the bottom of the mounting plate 31 for contacting the human skin.

[0060] With such a setting, the massage structure 3 is slidably arranged through the connecting rod 30 on the diversion hole 40 of the inner container 4, so as to realize its lifting movement along the vertical direction. At the same time, when the massage structure 3 moves up and down following the human skin, the connecting rod 30 will synchronously expand and contract in the inner container 4, thereby bringing out the essential oil in the inner container 4, enabling the essential oil to flow along the connecting rod 30 to the mounting plate 31 and the massage part 32 at the bottom end, and finally flowing to the human skin.

[0061] Optionally, referring to Figure 3 , a diversion groove 33 is formed on the connecting rod 30, and the diversion groove 33 extends along the length direction of the connecting rod 30.

[0062] With such a setting, the essential oil can quickly flow along the connecting rod 30 to the human skin, ensuring that the auxiliary application can be quickly carried out when the device is used for massaging and stimulating the vagus nerve.

[0063] Optionally, referring to Figure 1 , the connecting rod 30 is a spiral rod for rotating when it moves up and down relative to the inner container 4.

[0064] With such a setting, the spiral rod enables the connecting rod 30 to rotate during the up and down movement, and also enables the entire massage structure 3 to rotate, improving the massage stimulation effect.

[0065] Optionally, referring to Figure 1 , the massage part 32 is a plurality of universal wheels mounted on the bottom of the mounting plate 31, and the plurality of universal wheels are circumferentially arranged at intervals on the bottom of the mounting plate 31.

[0066] With such a setting, rolling massage is adopted to reduce skin friction and improve the comfort of the device when massaging the skin.

[0067] Optionally, referring to Figure 2 , it further includes a temperature adjustment structure 5, which includes:

[0068] The heat transfer pipe 50, which is spirally wound around the outer wall of the inner container 4;

[0069] The inflow port 501, which is connected to one end of the heat transfer pipe 50;

[0070] The outlet 502 is connected to the other end of the heat transfer pipe 50.

[0071] Among them, the inlet 501 and the outlet 502 are also connected to an external thermal circulating water device. The thermal circulating water device can generate hot water. The hot water flows in from the inlet 501, passes through the heat transfer pipe 50, and then flows back to the thermal circulating water device from the outlet 502.

[0072] With such a setting, the hot water in the heat transfer pipe 50 heats the essential oil in the inner tank 4, preventing the essential oil from being too cold and inhibiting the vagus nerve after contacting the skin.

[0073] Optionally, referring to Figure 2 , a buffer channel 503 is also connected in series in the middle of the heat transfer pipe 50. The heat transfer pipe 50 communicates with the buffer channel 503, and the buffer channel 503 is arranged at the bottom of the inner tank 4.

[0074] Among them, the buffer channel 503 is annular and arranged at the bottom of the inner tank 4, so that the hot water in the buffer channel 503 can also soothe the skin at the same time, achieving the effect of hot compress to prevent muscle relaxation.

[0075] Optionally, referring to Figure 2 , a slide rail 11 is provided on the inner wall of the outer casing 1. A slider 12 is slidably installed on the slide rail 11. The slider 12 is connected to the massage structure 3 and is used to lift and lower together with the massage structure 3. A detection structure 6 is also provided in the outer casing 1 to detect the position of the massage structure 3 and reflect the deformation degree of the human skin.

[0076] Among them, a connection groove is formed on the surface of the slider 12 facing away from the slide rail 11. The outer edge of the mounting plate 31 in the massage structure 3 extends into the connection groove and is in sliding contact with the upper and lower sides of the connection groove at the same time, so as to realize the smooth rotation of the mounting plate 31 in the connection groove. When the entire massage structure 3 is lifted and lowered, the mounting plate 31 can drive the slider 12 to lift and lower.

[0077] Optionally, referring to Figure 3 , the detection structure 6 includes:

[0078] A resistor 60, which is arranged on the slide rail 11;

[0079] A dial 61, one end of which is fixed to the slider 12 and the other end of which is slidably connected to the resistor 60;

[0080] An ammeter (not shown in the figure);

[0081] A power supply (not shown in the figure), and the resistor 60, the dial 61, the power supply and the ammeter are connected by wires.

[0082] With such a setting, since the installation disk 31 can drive the slider 12 to move up and down while rotating, the resistor 60 and the wiper 61 are equivalent to a slide rheostat. By changing the resistance value of the resistor 60 in the control circuit through the wiper 61, the magnitude of the current in the control circuit is further changed. By monitoring the sliding position of the slider 12 through the ammeter, the degree of skin protrusion and the magnitude of the negative pressure are further monitored, and thus the negative pressure magnitude and the start-stop time of the negative pressure assembly 2 can be controlled and adjusted in a timely and convenient manner.

[0083] The working principle and beneficial effects of the negative pressure type vagus nerve stimulation device provided by the embodiment of the present application are as follows:

[0084] The contact opening 10 at the bottom of the outer housing 1 is covered on the area of the human skin to be stimulated, and the negative pressure assembly 2 is used to form a negative pressure environment inside the outer housing 1. At this time, the covered human skin will be adsorbed into the outer housing 1, and then will come into contact with the massage structure 3 inside the outer housing 1, and will drive the massage structure 3 to rise or fall together during its rising or falling process. During this process, the human skin in this area will be massaged by the massage structure 3, and the vagus nerve inside it will be effectively stimulated. Therefore, when the negative pressure environment formed by the negative pressure assembly 2 inside the outer housing 1 is set, the deformation degree of the human skin and the obtained massage frequency will be stably controlled, which is suitable for general application.
