Adjustable low-frequency pulse electro-acupuncture therapeutic apparatus

Abstract

This utility model discloses an adjustable low-frequency pulse electroacupuncture therapy device, including a therapy device body. One end of the therapy device body has an output socket, and these output sockets are evenly distributed at one end of the therapy device body. A power socket is also provided at one end of the therapy device body. In this utility model, a wedge block is pulled into the through slot by a pulling rod. Since the diameter of the through slot is larger than the diameter of the wedge block, the inclined surface of the wedge block can be rotated. The patient can then move the treatment area and simultaneously pull the limiting rod out of the limiting slot. As the patient's treatment area moves, the winding roller rotates inside the housing, pulling the wire out of the outlet. The length of the wire can then be adjusted. The use of the winding roller reduces the possibility of haphazard placement of the guide wire, increasing the neatness of the wire placement. Furthermore, the wedge block and limiting gear reduce the possibility of the winding roller reversing, which could shorten the wire.

Description

Technical Field

[0001] This utility model relates to the technical field of pulse electroacupuncture therapy devices, specifically an adjustable low-frequency pulse electroacupuncture therapy device. Background Technology

[0002] The low-frequency pulse electroacupuncture therapy device is a medical device that combines traditional acupuncture therapy with modern low-frequency pulse electrical stimulation technology. It works by inserting acupuncture needles into acupoints and connecting them to the therapy device. The low-frequency pulse current output by the therapy device acts on the meridians and acupoints of the human body through the acupuncture needles. This low-frequency pulse current can simulate the body's own bioelectric signals, stimulate the nerves, muscles and other tissues under the acupoints, regulate the body's physiological functions, and thus achieve the purpose of treating diseases and relieving symptoms.

[0003] Therapeutic devices can typically generate various pulse waveforms, such as square waves, triangular waves, and sine waves. Different waveforms have different therapeutic effects. When patients need to move their bodies or adjust their treatment positions within a certain range, they cannot move because the wire length is fixed. This can lead to the wire being too long or too short, affecting the treatment process. Utility Model Content

[0004] The purpose of this invention is to address the problem that therapeutic instruments typically generate various pulse waveforms of different shapes, such as square waves, triangular waves, and sine waves, which have different therapeutic effects. When patients need to move their bodies or adjust their treatment positions within a certain range, the fixed length of the lead wire prevents movement, leading to the lead wire being too long or too short, thus affecting the treatment process. This invention provides an adjustable low-frequency pulse electroacupuncture therapeutic instrument.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable low-frequency pulse electroacupuncture therapy device, comprising a therapy device body, an output socket being provided at one end of the therapy device body, and the output sockets being evenly distributed at one end of the therapy device body, a power socket being provided at one end of the therapy device body, and a power switch being provided at one end of the therapy device body, characterized in that a mounting shell is fixedly installed at one end of the therapy device body, and a rotating shaft is fixedly installed inside the mounting shell, and a winding roller is evenly and symmetrically rotatably connected to the outer circumference of the rotating shaft, the interface of the winding roller and the output socket being at the same position, and a wire outlet being symmetrically opened at the top of the mounting shell, and the wire outlet being opened directly above the winding roller.

[0006] As a further embodiment of this utility model: a mounting block is fixedly installed at one end of the therapeutic instrument body, and the mounting block is symmetrically fixedly installed at one end of the therapeutic instrument body. A mounting groove is symmetrically opened at one end of the mounting shell, and the mounting groove is adapted to the mounting block. A threaded groove is opened at one end of both the mounting groove and the mounting block, and a threaded rod adapted to the threaded groove is threadedly connected to one end of the mounting shell.

[0007] As a further embodiment of this utility model: a driven bevel gear is fixedly installed at one end of the winding roller, a rotating shaft is rotatably connected inside the mounting housing, and a driving bevel gear is fixedly installed at one end of the rotating shaft, and the driving bevel gear and the driven bevel gear are meshed and connected. A rotating disk is rotatably connected at one end of the mounting housing, and the rotating shaft passes through the mounting housing and the rotating disk for fixed installation.

[0008] As a further embodiment of this utility model: a grip handle for workers to hold is fixedly installed at one end of the rotating disk, and limit slots are evenly opened around both the mounting shell and one end of the rotating disk, and a limit rod is inserted into one end of the rotating disk, the limit rod being adapted to the limit slot.

[0009] As a further embodiment of this utility model: a limiting gear is fixedly installed on one end of the winding roller opposite to the driven bevel gear; a through groove is opened at the top of the inner part of the mounting housing, and the through groove is located directly above the limiting gear; a wedge block is slidably connected inside the through groove, and the wedge block is matched with the tooth groove of the limiting gear for limiting; a pull rod is slidably connected at the top of the mounting housing, and the pull rod passes through the through groove and is fixedly installed with the wedge block; a return spring is fixedly installed inside the through groove, and one end of the return spring is fixedly installed with the wedge block; the return spring is sleeved on the outer periphery of the pull rod.

[0010] As a further improvement of this utility model: a timer is provided at the top of the therapeutic instrument body, a frequency adjustment knob is provided at the top of the therapeutic instrument body, a function conversion knob is provided at the top of the therapeutic instrument body, a continuous frequency adjustment knob is provided at the top of the therapeutic instrument body, an output indicator light is provided at the top of the therapeutic instrument body, a power indicator light is provided at the top of the therapeutic instrument body, and an intensity output switch knob is uniformly rotatably connected to the top of the therapeutic instrument body.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, a wedge block is pulled into the through slot by a pull rod. Since the diameter of the through slot is larger than the diameter of the wedge block, the inclined surface of the wedge block can be rotated. The patient can then move the treatment area and pull the limiting rod out of the limiting slot. As the patient's treatment area moves, the winding roller rotates inside the housing, which pulls the wire out of the outlet and adjusts the wire length. The winding roller reduces the random placement of the guide and increases the neatness of the wire placement. The wedge block and the limiting gear reduce the possibility of the winding roller reversing, which could shorten the wire.

[0013] In this invention, the wedge block is pulled into the through groove by a pull rod and the direction of the inclined plane is rotated. At this time, the worker drives the rotating disk to rotate by holding the handle. As the rotating disk rotates, it drives the active bevel gear to rotate through the rotating shaft. Since the active bevel gear and the driven bevel gear are meshed, when the active bevel gear rotates, it will drive the driven bevel gear to rotate together, which in turn drives the winding roller to rotate, thereby recovering the wire and reducing the mess caused by the wire being placed randomly on the outside.

The embodiments of this utility model will be described below based on its overall structure.

[0025] Reference Figures 1 to 8 In this embodiment of the present invention, an adjustable low-frequency pulse electroacupuncture therapy device includes a therapy device body 1, an output socket 2 is provided at one end of the therapy device body 1, and the output sockets 2 are evenly distributed at one end of the therapy device body 1. A power socket 29 is provided at one end of the therapy device body 1, and a power switch 30 is provided at one end of the therapy device body 1. The device body 1 is characterized in that a mounting shell 3 is fixedly installed at one end of the therapy device body 1, and a rotating shaft 8 is fixedly installed inside the mounting shell 3. A winding roller 9 is evenly and symmetrically rotatably connected to the outer circumference of the rotating shaft 8. The interface of the winding roller 9 and the output socket 2 is located at the same position. A wire outlet 10 is symmetrically provided at the top of the mounting shell 3, and the wire outlet 10 is located directly above the winding roller 9.

[0026] The above scheme is adopted: the outer shell of the treatment device body 1 is made of high-quality plastic, which is compact and sturdy. The winding roller 9 and the output socket 2 are in the same position. The outer circumference of the rotating shaft 8 and the two sides of the winding roller 9 are provided with protrusions to prevent the winding roller 9 from deviating when rotating, thereby increasing the stability of rotation. The mounting shell 3 is made of the same material as the treatment device body 1.

[0027] Reference Figures 1 to 8 The therapeutic instrument body 1 has a mounting block 4 fixedly installed at one end, and the mounting block 4 is symmetrically fixedly installed at one end of the therapeutic instrument body 1. The mounting shell 3 has a mounting groove 5 symmetrically opened at one end, and the mounting groove 5 is compatible with the mounting block 4. Both the mounting groove 5 and the mounting block 4 have a threaded groove 6 at one end, and the mounting shell 3 has a threaded rod 7 that is compatible with the threaded groove 6 at one end.

[0028] Using the above solution: the size of the mounting block 4 and the mounting groove 5 are compatible. During installation, simply insert the mounting block 4 into the mounting groove 5, and then thread the threaded rod 7 into the threaded groove 6 to complete the installation and fixation of the housing 3 and the treatment device body 1.

[0029] Reference Figures 1 to 8 One end of the winding roller 9 is fixedly installed with a driven bevel gear 11. The mounting housing 3 is rotatably connected with a rotating shaft 12, and one end of the rotating shaft 12 is fixedly installed with a driving bevel gear 13, which meshes with the driven bevel gear 11. One end of the mounting housing 3 is rotatably connected with a rotating disk 14, and the rotating shaft 12 passes through the mounting housing 3 and the rotating disk 14 for fixed installation. One end of the rotating disk 14 is fixedly installed with a grip handle 17 for workers to hold. Limit slots 15 are evenly opened around one end of both the mounting housing 3 and the rotating disk 14, and a limit rod 16 is inserted into one end of the rotating disk 14. The limit rod 16 is adapted to the limit slot 15.

[0030] The above solution is adopted: the outer walls of both the limiting rod 16 and the limiting slot 15 are provided with friction layers to increase the limiting stability, increase the friction force when fixed, and reduce the situation where the limiting rod 16 disengages from the limiting slot 15 when fixed.

[0031] Reference Figures 1 to 8 A limiting gear 18 is fixedly installed on one end of the winding roller 9 opposite to the driven bevel gear 11. A through groove 19 is opened at the top of the inner part of the mounting housing 3, and the through groove 19 is located directly above the limiting gear 18. A wedge block 20 is slidably connected inside the through groove 19, and the wedge block 20 is matched with the tooth groove of the limiting gear 18 for limiting. A pull rod 21 is slidably connected at the top of the mounting housing 3, and the pull rod 21 passes through the through groove 19 and is fixedly installed with the wedge block 20. A return spring 22 is fixedly installed inside the through groove 19, and one end of the return spring 22 is fixedly installed with the wedge block 20. The return spring 22 is sleeved on the outer periphery of the pull rod 21.

[0032] Using the above scheme: the diameter of the through groove 19 is larger than the diameter of the wedge block 20. When the wedge block 20 is pulled into the through groove 19 by the pull rod 21, the wedge block 20 can be rotated to change the direction of the inclined plane. By changing the direction of the wedge block 20, the rotation direction of the winding roller 9 can be adjusted.

[0033] Reference Figures 1 to 8 The top of the treatment device body 1 is equipped with a timer 31, a frequency adjustment knob 24, a function conversion knob 25, a continuous frequency adjustment knob 27, an output indicator light 23, a power indicator light 26, and an intensity output switch knob 28 that is uniformly rotated at the top of the treatment device body 1.

[0034] The above scheme is adopted: Continuous frequency adjustment knob 27 is used to adjust the continuous frequency when the function conversion knob is set to continuous wave; frequency adjustment knob 24 is used to adjust the frequency when the function conversion knob is set to dense / sparse wave or discontinuous wave; output indicator light 23 indicates the frequency of continuous wave, dense / sparse wave, and discontinuous wave; timer 31 is normally open / 15 / 20 / 25 / 30 / 35 / 40min with seven selectable levels and an error of ±10%.

[0035] The working principle of this utility model is as follows: When using the treatment device body 1, when the patient needs to move the treatment area, the wedge block 20 is pulled into the through groove 19 by pulling the rod 21. Since the diameter of the through groove 19 is larger than the diameter of the wedge block 20, the inclined surface of the wedge block 20 can be rotated at this time, and then the patient can move the treatment area. At the same time, the limiting rod 16 is pulled out of the limiting slot 15. Then, as the patient's treatment area moves, the winding roller 9 will rotate inside the mounting housing 3, which will drive the wire to be pulled out of the wire outlet 10, and the length of the wire can be adjusted. At the same time, by using the winding roller 9, the random placement of the guide can be reduced, and the neatness of the wire placement can be increased. Meanwhile, the wedge block 20 and the limiting gear 18 can reduce the possibility of the winding roller 9 reversing and causing the wire to shorten. When it is necessary to recycle the wire, the wedge block 20 is pulled into the through groove 19 by pulling the lever 21 and the direction of the inclined plane is rotated. At this time, the operator drives the rotating disk 14 to rotate by holding the handle 17. As the rotating disk 14 rotates, it will drive the driving bevel gear 13 to rotate through the rotating shaft 12. Since the driving bevel gear 13 is meshed with the driven bevel gear 11, when the driving bevel gear 13 rotates, it will drive the driven bevel gear 11 to rotate together, thereby driving the winding roller 9 to rotate and thus recycling the wire, reducing the mess caused by the wire being placed randomly outside.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
