Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a rhinitis treatment instrument. Background Art

[0002] Rhinitis is an inflammation of the nasal mucosa. Patients often experience symptoms such as nasal congestion, nasal itching, runny nose, and sneezing, which seriously affect the work and life of patients. One of the methods for treating rhinitis is to use an instrument to perform physical therapy on the nasal cavity to improve the local blood circulation of the nose and achieve the improvement or elimination of rhinitis symptoms. Commonly used physical therapy methods include laser irradiation or electrotherapy of the nasal cavity. Such instruments usually use a main unit electrically connected to a wire fixed with a physical therapy electrode. When in use, the physical therapy electrode is inserted into the nasal cavity, and the main unit controls the intensity and time of physical therapy on the nasal cavity through the wire.

[0003] Since it is necessary to connect the main unit and the physical therapy electrode with a wire, the wire is easily broken and entangled, and the body movement will be restricted during use, bringing many inconveniences to use and carrying; the physical therapy electrode is fixed to the wire, and when one of them is damaged or the physical therapy electrode needs to be replaced, the whole needs to be replaced, resulting in waste of materials; the separation of the main unit and the physical therapy electrode will also cause cumbersome production and reduce production efficiency. In view of this, it has become an urgent problem to design a rhinitis treatment instrument without wire connection, with replaceable physical therapy electrodes, simple operation and portability. Summary of the Invention

[0004] In order to overcome the deficiencies of the above problems, a rhinitis treatment instrument is designed, on which a detachable physical therapy electrode is inserted, and the electrotherapy method for the nasal cavity is adopted, aiming to achieve wire-free connection, replaceable physical therapy electrodes, simple operation and portability.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a rhinitis treatment instrument, including a main unit and an electrode fixed outside the main unit. The main unit includes a housing, a circuit board fixed inside the housing, and a battery installed inside the housing and electrically connected to the circuit board; the electrode includes an external nasal electrode, a connecting plate installed on the inner side of the bottom of the external nasal electrode, and an internal nasal electrode embedded in the connecting plate; the internal nasal electrode is provided with two hollow columns corresponding to the nostrils protruding upward from the connecting plate; the external nasal electrode and the internal nasal electrode are insulated from each other and are respectively electrically connected to the circuit board.

[0006] Further, it further includes an electrode bracket, one side of which is provided with an outwardly protruding hook and a hollow column A; the left and right sides and the top of the external nasal electrode are turned outwards to form a U-shaped groove with its outside; the electrode bracket is inserted into the U-shaped groove, and the hook and the hollow column A on it pass through the holes on the side wall of the U-shaped groove and are fixed to the housing together and press the side wall of the U-shaped groove; the external nasal electrode and the main unit form a structure with a lower opening and a suspended interior.

[0007] Further, a connecting column with a cuboid upper part and an inverted frustum of a cone lower part protrudes downward from the center of the bottom of the external nasal electrode. The front part of the connecting plate is sleeved on the cuboid of the connecting column, and the large end of the frustum of the cone hooks its bottom.

[0008] Further, two blind holes are provided at the rear part of the housing. A convex metal column is embedded at the bottom of each blind hole. The convex ends of the metal columns are respectively inserted into the hollow columns B and C protruding outward from the external nasal electrode and the internal nasal electrode, and both are in interference-fit electrical connection. The other ends of the metal columns are respectively electrically connected to the circuit board inside the housing.

[0009] Further, both the external nasal electrode and the internal nasal electrode are made of conductive rubber, and the connecting plate is made of insulating rubber.

Two rectangular strap holes 115 are symmetrically arranged on the left and right sides of the housing 11 for connecting the housing 11 and the fixing strap; the internal nasal electrode 23 is provided with two hollow columns 231 corresponding to the nostrils protruding upward from the connection plate 22, and a physiotherapy electrode can be inserted into the central hole of each hollow column 231; the circuit board 12 is provided with a signal control unit for controlling the time and intensity of electrotherapy.

[0025] Referring to Figure 2 , Figure 3 and Figure 4, the implementation of the main unit 1 is described. Inside the housing 11, a circuit board 12 is fixed. On the left and right sides of the circuit board 12, there is a battery compartment 113 for placing a battery 13 respectively. The battery 13 is electrically connected to the circuit board 12 and provides energy for the operation of the rhinitis treatment device. The battery 13 can be a dry battery or a lithium battery. In this embodiment, two No. 7 dry batteries are selected. To facilitate the replacement of the battery 13, a detachable battery cover 114 covering the battery 13 is provided at the front of the housing 11. Two blind holes 111 are provided at the lower right of the rear of the housing 11. At the bottom of each blind hole 111, a metal post 112 is embedded. One end of the metal post 112 is electrically connected to the circuit board 12 inside the housing 11 respectively, and the other end protrudes outwards from the bottom of the blind hole 111 for electrical connection with the external nasal electrode 21 and the internal nasal electrode 23. Two rectangular strap holes 115 are symmetrically provided on the left and right sides of the housing 11 for fixing the fixing strap on the housing 11. During treatment, the rhinitis treatment device is fixed on the nose using the fixing strap. The fixing strap can be an elastic elastic band.

[0026] Referring to Figure 6 , the implementation of the external nasal electrode 21 is described. The left, right and top sides of the external nasal electrode 21 are turned outwards to form a U-shaped groove 211 on its outside; holes 212 for assembly and a protruding hollow post B214 are left on the side wall of the U-shaped groove 211. The hollow post B214 is used for electrical connection with a metal post 112 embedded in the housing 11; a connecting post 213 with a cuboid upper part and an inverted frustum lower part protrudes downwards from the center of the bottom of the external nasal electrode 21. The connecting post 213 is used to connect the external nasal electrode 21 and the connecting plate 22 together.

[0027] Referring to Figure 2 , Figure 3 and Figure 5 , the implementation of the electrode 2 is described. The internal nasal electrode 23 is embedded in the bottom of the connecting plate 22. Two hollow columns 231 provided on the internal nasal electrode 23 protrude upwards from the connecting plate 22. The two hollow columns 231 correspond to the two nostrils. A conductive physiotherapy electrode can be inserted into the central hole of each hollow column 231. The two are in interference fit and are detachably electrically connected. A hollow post C232 protrudes outwards from the front of the internal nasal electrode 23 for electrical connection with another metal post 112 embedded in the housing 11. The front part of the connecting plate 22 is sleeved on the cuboid of the connecting post 213 at the bottom of the external nasal electrode 21 and its bottom is hooked by the large end of the frustum to ensure that the connecting plate 22 cannot rotate relative to the external nasal electrode 21. After the assembled electrode 2, the external nasal electrode 21 and the internal nasal electrode 23 are insulated from each other.

[0028] To improve the wearing comfort, the parts forming the electrode 2 are all made of soft materials. Among them, the external nasal electrode 21 and the internal nasal electrode 23 are both made of conductive rubber, and the connecting plate 22 is made of insulating rubber.

[0029] Also, since one end of the physiotherapy electrode needs to be inserted into the hollow column 231 of the nasal electrode 23, and the other end needs to be inserted into the nostril, the soft hollow column 231 can also adaptively deform and adjust according to the distance change between the two nostrils.

[0030] Refer to Figures 2 to 6 , and describe the implementation manner of the assembly of the main unit 1 and the electrode 2. An electrode bracket 3 is provided to fix the electrode 2 outside the main unit 1. First, the electrode bracket 3 is installed in the U-shaped groove 211 of the external nasal electrode 21, and the hook 31 and the hollow column A32 provided on one side of the electrode bracket 3 pass through the hole 212 on the side wall of the U-shaped groove 211; then the hollow column B214 on the external nasal electrode 21 and the hollow column C232 on the internal nasal electrode 23 are respectively inserted into the blind holes 111 on the upper surface of the housing 11, and the metal columns 112 embedded at the bottom of the blind holes 111 are respectively inserted into the central holes of the hollow column B214 and the hollow column C232. The metal columns 112 and the hollow column B214, the hollow column C232 are in interference fit to ensure the reliability of the electrical connection; then the electrode bracket 3 is fixed to the housing 11, wherein the hook 31 hooks the inside of the housing 11, and the hollow column A32 and the housing 11 can be fixed together with screws. Thus, the electrode bracket 3 and the housing 11 press the side wall of the U-shaped groove 211 on the external nasal electrode 21, that is, the electrode 2 is fixed outside the main unit 1; finally, the battery cover 114 is buckled on the front part of the housing 11. For the convenience of disassembling the battery cover 114, it can be connected to the housing 11 by common hooks or by magnetic adsorption. In this embodiment, the hook connection is adopted.

[0031] After assembly, the main unit 1 and the external nasal electrode 21 form a structure with a lower opening and a suspended interior, so that the external nasal electrode 21 has appropriate deformation space, can adapt to different nasal shapes, and also ensures good contact between the external nasal electrode 21 and the nasal skin.

[0032] During use, two No. 7 dry batteries 13 are installed in the battery compartment 113 according to the polarity requirements, the battery cover 114 is buckled, the fixing belt passes through the belt hole 115 and is fixed on the housing 11, and one end of each of the two conductive physiotherapy electrodes is respectively inserted into the central hole of the two hollow columns 231 of the internal nasal electrode 23, and the two are in interference fit for electrical connection. To improve the curative effect, a layer of ointment can also be applied to the outer surface of the part where the physiotherapy electrode is inserted into the nostril. Wear the rhinitis treatment instrument on the nose, the external nasal electrode 21 contacts the nasal surface skin, the physiotherapy electrode is inserted into the nostril, and the rhinitis treatment instrument is fixed on the nose with the fixing belt. Start the rhinitis treatment instrument, and the rhinitis can be treated by setting the intensity and time of electrotherapy through the circuit board 12. There is no wire entanglement during the treatment process and it does not affect body activities; after the treatment is over, remove the physiotherapy electrode for cleaning or replacement.
