Description

Technical Field

[0001] The utility model relates to the technical field of acupuncture, and in particular to a wire winding device of an electric acupuncture instrument. Background Art

[0002] Acupuncture is a general term for acupuncture and moxibustion, and has become one of the commonly used treatment methods today. Acupuncture is a clinical discipline guided by Traditional Chinese Medicine theory that uses acupuncture and moxibustion to prevent and treat diseases. Its content includes meridians, acupoints, acupuncture methods, clinical treatments, etc. Acupuncture has the advantages of wide adaptability, significant therapeutic effects, economy, safety, and ease of operation. Today, it has become one of the commonly used treatment methods. After continuous development and evolution, acupuncture instruments have become more and more diverse and more advanced. In clinical practice, the use of electroacupuncture instruments is becoming more and more common. During the treatment process using electroacupuncture instruments, one end of the electric wire of the electric acupuncture instrument is connected to the electric acupuncture needle to send out a pulse signal, and the other end of the wire is connected to the acupuncture needle. The acupuncture needle receives the pulse signal, thereby controlling the pulse signal of the acupuncture needle to treat the patient and achieve better treatment results. However, the wires of current electroacupuncture instruments need to be manually arranged and tightened when not in use. Usually, an electroacupuncture instrument has more than a dozen long wires, which are cumbersome to arrange. When not arranged, they will become tangled, affecting the work efficiency of medical staff. Therefore, it is necessary to invent a wire winding device for an electroacupuncture instrument.

[0003] Existing wire winding structures, such as the wire winding device for an electroacupuncture apparatus disclosed in Patent 201620309174.0, can also achieve the wire winding function, but it is a separate wire winding device and cannot be placed inside the electroacupuncture apparatus. Patent 202123426956.2 also discloses an acupuncture wire winding device that is applied externally to the electroacupuncture apparatus and cannot achieve the integration of the wire winding and the electroacupuncture apparatus. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a wire winding device for an electro-acupuncture instrument which has a simple structure and effectively prevents the wires of the electro-acupuncture instrument from being entangled or knotted.

[0005] The utility model solves the above-mentioned technical problems as follows:

[0006] A wire winding device for an electroacupuncture apparatus, the wire winding device being arranged inside the electroacupuncture apparatus, the wire winding device comprising: a base fixedly connected to the electroacupuncture apparatus, a wire winding roller in rolling connection with the base, a wire wound around the wire winding roller, and a reset mechanism;

[0007] The upper end of the base is provided with two parallel brackets, and the winding roller is mounted between the two parallel brackets; the lower end of the base is provided with a guide rail, the end of the guide rail is provided with a sleeve, and a first spring is provided in the sleeve; the base is also fixed with an inner ratchet coaxial with the winding roller;

[0008] The winding roller is provided with an axial hole along the axial direction, and the axial hole is embedded with a conductive connector that rotates together with the winding roller;

[0009] The starting end of the wire passes through the winding roller and contacts the conductive connector, and the end of the wire extends out of the electro-acupuncture instrument;

[0010] The reset mechanism includes: a linkage shaft that can move along the axial direction of the winding roller and rotate together with the winding roller, an outer ratchet mounted on the linkage shaft, a sleeve, a slider fixed to the sleeve, a coil spring arranged inside the sleeve, and a button for triggering contraction; the front end of the linkage shaft passes through the sleeve, the inner ratchet is inserted into the shaft hole, the rear end of the linkage shaft is fixed to the starting end of the coil spring, and the end of the coil spring is installed on the inner wall of the sleeve; the outer ratchet and the inner ratchet form a directional rotation fit; the slider and the guide rail form a guide rail pair; the top end of the button extends out of the electric acupuncture instrument, the bottom end of the button is inserted into the sleeve and abuts against the first spring, and the contact surface of the button and the sleeve is provided with an extrusion slope.

[0011] Furthermore, a second spring is provided between the guide rail and the slider, the front end of the second spring abuts against the inner wall of the guide rail, and the end of the second spring abuts against the front end of the slider.

[0012] Furthermore, the outer ratchet is made of rubber, the inner ratchet is made of plastic, and the conductive connector is a copper connector. During use, this design forms a directional rotational fit between the outer and inner ratchet wheels, ensuring that after the wire is pulled out, the directional rotational fit between the outer and inner ratchet wheels prevents the wire from automatically retracting. During wire extraction, the outer ratchet (made of rubber) and the inner ratchet (made of plastic) rotate relative to each other, causing the teeth of the outer ratchet to deform during relative rotation, allowing for smooth wire extraction.

[0013] Furthermore, the guide rails are two parallel rails, the sliders are two parallel rails, the second springs are two rails, the sleeves are two rails, and the first springs are two rails. This design is to ensure that the reset mechanism works more smoothly.

[0014] Furthermore, the linkage shaft is a hexagonal prism, with one end of the winding roller's shaft hole being a circular hole for inserting the conductive connector and the other end being a hexagonal hole for inserting the hexagonal prism. This design ensures that during wire extraction, the winding roller drives the hexagonal prism to rotate together, while during wire retraction, the coil spring drives the hexagonal prism and winding roller to rotate together. This allows for free wire retraction and prevents the wires from becoming entangled or knotted.

[0015] Furthermore, the end of the wire is connected to an acupuncture plug for connecting an acupuncture needle, thereby achieving the transmission of electroacupuncture pulse signals.

[0016] Furthermore, the number of winding devices is N, where N ≥ 1. This design allows for multiple winding devices, facilitating the installation of multiple wires and multiple acupuncture plugs. Each wire can be independently retracted and retracted without interfering with each other. Furthermore, acupuncture can be performed on multiple sites simultaneously.

[0017] Furthermore, the extrusion slope is 45 degrees. This design utilizes external force, such as a finger, to press the button, causing the first spring in the sleeve to contract, and the extrusion slope to squeeze the housing. When the extrusion slope is 45 degrees, extrusion is more convenient and more efficient.

[0018] Furthermore, the electro-acupuncture apparatus further comprises a housing for accommodating the winding device, and a panel covering the housing, wherein the panel is provided with a through hole for the wire to pass through, and the wire passes through the through hole and is connected to the acupuncture plug;

[0019] The panel is also provided with an avoidance hole for the button to pass through, and the top end of the button passes through the avoidance hole and is exposed to the outside of the panel.

[0020] The use process of this design is that when the medical staff pulls the wire, the wire drives the winding roller to rotate, and the winding roller drives the conductive connector and the hexagonal prism to rotate. Since the outer ratchet is sleeved and fixed on the hexagonal prism, the hexagonal prism drives the outer ratchet to rotate. Due to the action of the second spring in the guide rail, the end of the slider is pushed to abut the guide rail. At this time, the outer ratchet and the inner ratchet form a directional fit. When the outer ratchet rotates relative to the inner ratchet sleeved on the outside, the teeth of the outer ratchet are deformed to complete the rotation. At the same time, the rotation of the hexagonal prism also drives the contraction of the coil spring. When the wire is pulled to the appropriate length, the outer ratchet and the inner ratchet are in a directional fit to ensure that the wire cannot be recovered. At this time, the acupuncture connector is connected to the acupuncture needle, thereby realizing the transmission of electroacupuncture pulse signals for treatment.

[0021] When the treatment is completed and the guide wire needs to be retracted, the medical staff can press the button, which squeezes the first spring in the sleeve. The first spring contracts, and the extrusion slope squeezes the sleeve, causing the sleeve to slide forward. The sleeve drives the hexagonal prism to move forward, and the hexagonal prism drives the outer ratchet to extend the inner ratchet. The directional cooperation between the outer ratchet and the inner ratchet is released. At this time, the coil spring recovers from the contracted state, and the coil spring drives the hexagonal prism to reverse, and the hexagonal prism drives the winding roller to reverse. The wire is contracted and wound on the winding roller, completing the arrangement of the wire and preventing the wire from being entangled.

[0022] The utility model has the following advantages over the prior art:

[0023] 1. This design incorporates a wire winding device for an electroacupuncture instrument. The winding device is located inside the instrument, with only the acupuncture plug and buttons exposed. This truly integrates the instrument and the wire winding device, saving space while simplifying the winding of the instrument's wires.

[0024] 2. This design can have multiple winding devices, which is convenient for setting up multiple wires and multiple acupuncture plugs. The retraction and retraction of each wire are independent and will not interfere with each other. At the same time, acupuncture can be performed on multiple parts at once.

[0025] 3. The wire winding device of the electric acupuncture instrument designed in this paper is aimed at the problems encountered by medical staff in their actual work. It has a humanized design, is simple and convenient, and has strong practicality.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 4 As shown, a wire winding device 10 of an electro-acupuncture apparatus is provided inside the electro-acupuncture apparatus 9 and comprises: a base 1 fixedly connected to the electro-acupuncture apparatus 9, a wire winding roller 2 connected in a rolling manner to the base 1, a wire 3 wound around the wire winding roller 2, and a reset mechanism 4;

[0037] like Figure 4 、 Figure 8 As shown, the upper end of the base 1 is provided with two parallel brackets 11, and the winding roller 3 is mounted between the two parallel brackets 11; the lower end of the base 1 is provided with a guide rail 12, the end of the guide rail 12 is installed with a sleeve 13, and a first spring 14 is provided in the sleeve 13; the base 1 is also fixed with an inner ratchet 7 coaxial with the winding roller 2;

[0038] like Figure 4 、 Figure 5 As shown, the winding roller 2 is provided with an axial hole 21 along the axial direction, and the axial hole 21 is embedded with a conductive connector 22 that rotates together with the winding roller 2;

[0039] like Figure 4 、 Figure 5 、 Figure 1 As shown, the starting end of the wire 3 passes through the winding roller 2 and contacts the conductive connector 22, and the end of the wire 3 extends out of the electro-acupuncture instrument 9;

[0040] like Figure 4 、 Figure 6 As shown, the reset mechanism 4 includes: a linkage shaft 5 that can move axially along the winding roller 2 and rotate with the winding roller 2, an outer ratchet 8 sleeved on the linkage shaft 5, a sleeve 41, a slider 42 fixed to the sleeve 41, a coil spring 51 arranged inside the sleeve 41 and a button 6 for triggering contraction; the front end of the linkage shaft 5 passes through the sleeve 41, the inner ratchet 7 is inserted into the shaft hole 21, the rear end of the linkage shaft 5 is fixed to the starting end of the coil spring 51, and the end of the coil spring 51 is installed on the inner wall of the sleeve 41; the outer ratchet 8 and the inner ratchet 7 form a directional rotation fit; the slider 42 and the guide rail 12 form a guide rail pair; the top end of the button 6 extends out of the electric acupuncture instrument 9, the bottom end of the button 6 is inserted into the sleeve 13, and abuts against the first spring 14, and the surface of the button 6 in contact with the sleeve 41 is provided with an extrusion slope 43.

[0041] like Figure 7 、 Figure 8As shown, a second spring 15 is provided between the guide rail 12 and the slider 42 , the front end of the second spring 15 abuts against the inner wall of the guide rail 12 , and the end of the second spring 15 abuts against the front end of the slider 42 .

[0042] like Figure 4 、 Figure 5 、 Figure 7 As shown, the outer ratchet 8 is made of rubber, the inner ratchet 7 is made of plastic, and the conductive connector 22 is a copper connector. During use, this design forms a directional rotational fit between the outer ratchet 8 and the inner ratchet 7, ensuring that after the wire 3 is pulled out, the directional rotational fit between the outer ratchet 8 and the inner ratchet 7 prevents the wire 3 from automatically retracting. During the process of pulling the wire 3, the outer ratchet 8 (made of rubber) and the inner ratchet 7 (made of plastic) deform during relative rotation, allowing for smooth extraction of the wire 3.

[0043] like Figure 4 As shown, there are two parallel guide rails 12, two parallel sliders, two second springs 15, two sleeves, and two first springs 14. This design is to ensure that the reset mechanism 4 works more smoothly.

[0044] like Figure 4 、 Figure 7 As shown, the linkage shaft 5 is a hexagonal prism 5. The shaft hole 21 of the winding roller 2 has a circular hole at one end for inserting the conductive connector 22, and a hexagonal hole at the other end for inserting the hexagonal prism 5. This design ensures that during the wire 3 withdrawal process, the winding roller 2 drives the hexagonal prism 5 to rotate together. During the wire retraction process, the coil spring 51 drives the hexagonal prism 5 and the winding roller 2 to rotate together. This allows the wire 3 to retract freely and prevents the wire 3 from becoming entangled or knotted.

[0045] like Figure 4 、 Figure 1 As shown, the end of the wire 3 is connected to an acupuncture plug 31 for connecting an acupuncture needle, thereby realizing the transmission of electroacupuncture pulse signals.

[0046] like Figure 1 、 Figure 2 As shown, there are N winding devices 10, where N ≥ 1. This design allows for four winding devices, facilitating the installation of four wires 3 and four acupuncture plugs. Each wire 3 can be independently retracted and retracted without interfering with each other. Furthermore, acupuncture can be performed on multiple sites simultaneously.

[0047] like Figure 4 As shown, the extrusion slope 43 is 45 degrees. This design utilizes external force, such as a finger, to press the button 6, causing the first spring 14 in the sleeve 13 to contract, and the extrusion slope 43 to squeeze the housing 41. When the extrusion slope 43 is 45 degrees, extrusion is more convenient and more efficient.

[0048] like Figure 1 、 Figure 2 As shown, the electro-acupuncture apparatus 9 further includes a housing 92 for accommodating the winding device 10, and a panel 91 covering the housing 92. The panel is provided with a through hole 93 for the wire 3 to pass through. The wire 3 passes through the through hole 93 and is connected to the acupuncture plug 31.

[0049] The panel 91 is further provided with an escape hole 94 for the button 6 to pass through, and the top end of the button 6 passes through the escape hole 94 and is exposed to the outside of the panel 91.

[0050] like Figures 4 to 8 As shown, the use process of this design is that when the medical staff pulls the wire 3, the wire 3 drives the winding roller 2 to rotate, and the winding roller 2 drives the conductive connector 22 and the hexagonal prism 5 to rotate. Since the outer ratchet 8 is mounted and fixed on the hexagonal prism 5, the hexagonal prism 5 drives the outer ratchet 8 to rotate. Due to the action of the second spring 15 in the guide rail 12, the end of the slider 42 is pushed to abut the guide rail 12. At this time, the outer ratchet 8 and the inner ratchet 7 just form a directional fit. When the outer ratchet 8 rotates relative to the inner ratchet 7 mounted on the outside, the teeth of the outer ratchet 8 are deformed to complete the rotation. At the same time, the rotation of the hexagonal prism 5 also drives the contraction of the coil spring 51. When the wire 3 is pulled to the appropriate length, since the outer ratchet 8 and the inner ratchet 7 are in a directional fit, it is ensured that the wire 3 cannot be retracted. At this time, the acupuncture connector 31 is connected to the acupuncture needle, thereby realizing the transmission of the electroacupuncture pulse signal for treatment.

[0051] When the treatment is completed and the guide wire 3 needs to be retracted, the medical staff can press the button 6, which squeezes the first spring 14 in the sleeve 13. The first spring 14 contracts, and the extrusion slope 43 squeezes the sleeve 41, causing the sleeve 41 to slide forward. The sleeve 41 drives the hexagonal prism 5 to move forward, and the hexagonal prism 5 drives the outer ratchet 8 to extend out of the inner ratchet 7. The directional cooperation between the outer ratchet 8 and the inner ratchet 7 is released. At this time, the coil spring 51 recovers from the contracted state, and the coil spring 51 drives the hexagonal prism 5 to reverse, and the hexagonal prism 5 drives the winding roller 2 to reverse. The guide wire 3 is contracted and wound on the winding roller 2, completing the arrangement of the guide wire 3 and achieving the purpose of preventing the guide wire 3 from being entangled.

[0052] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
