Description

Technical Field

[0001] This utility model relates to an acupuncture device, and more particularly to an adhesive ultrasonic acupuncture device. Background Technology

[0002] Acupuncture is a traditional treatment method in Traditional Chinese Medicine, including acupuncture, moxibustion, and cupping. Among them, acupuncture refers to the use of needles (such as metal acupuncture needles) to stimulate acupoints on the body through certain techniques to prevent and treat diseases. It is the most widely used and applied acupuncture treatment method in clinical practice throughout history.

[0003] To form a needle-shaped sound field, existing ultrasonic acupuncture devices generally employ three methods: 1) using a spherical self-focusing ultrasonic transducer; 2) using a planar ultrasonic transducer with a focusing acoustic lens; and 3) using a multi-element phased array ultrasonic transducer.

[0004] Spherical self-focusing ultrasound transducers have complex manufacturing processes, low yield rates, and high costs. Furthermore, they are prone to generating high temperatures at the focal point, causing tissue damage. Planar ultrasound transducers with focusing lenses increase the size of the treatment head due to the lens, and are generally used in handheld treatment heads, making them unsuitable for simultaneous acupuncture treatment of multiple acupoints. Multi-element phased array ultrasound transducers have complex manufacturing processes and control systems, resulting in high costs and hindering widespread adoption. Utility Model Content

[0005] This invention provides an adhesive ultrasonic acupuncture device to overcome the shortcomings of existing handheld ultrasonic acupuncture devices that cannot treat multiple acupoints simultaneously.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model discloses an adhesive ultrasonic acupuncture device, including an ultrasonic acupuncture head, which is nested in an adhesive soft sleeve. The ultrasonic acupuncture head is electrically connected to a driver. The ultrasonic acupuncture head has at least two ultrasonic transducer assemblies for stimulating acupoints evenly distributed along the circumference and forming an angle with the longitudinal axis. Two adjacent ultrasonic transducer assemblies generate ultrasonic waves through vibration, which are superimposed to form a needle-shaped composite sound field.

[0008] Furthermore, the ultrasonic acupuncture head is connected to the driver via a cable or via a connector located thereon.

[0009] Furthermore, the ultrasonic acupuncture head includes a base, an ultrasonic transducer assembly is sleeved inside the base, a thermistor is provided on the upper surface of the base, and a housing is sleeved on top, with a cable outlet on the housing for a cable to pass through.

[0010] Furthermore, the ultrasonic transducer assembly includes a mounting base and a piezoelectric element installed therein. The piezoelectric element is a sheet-like piezoelectric ceramic or piezoelectric composite material. Metal electrodes are attached to the upper and lower surfaces of the piezoelectric element and are connected to the corresponding wires in the cable by brazing. The mounting base is made of metal or engineering plastic and is in the form of a thin sheet. The piezoelectric element and the mounting base are tightly connected by adhesive. The ultrasonic waves generated by the piezoelectric element can propagate into human tissue through the mounting base.

[0011] Furthermore, the thermistor is bonded to the corresponding groove in the base with thermally conductive silicone, located next to the ultrasonic transducer assembly, and connected to the corresponding wire in the cable by brazing. It is used to measure the temperature near the ultrasonic transducer assembly to prevent excessive temperature from damaging human skin.

[0012] Furthermore, the ultrasonic transducer assembly includes ultrasonic transducer assembly #1 and ultrasonic transducer assembly #2, each of which can emit a center frequency of 3.0MHz and an acoustic power of 0.1W / cm². 2 ~3.0W / cm 2 Ultrasound.

[0013] Furthermore, the base is made of engineering plastic, and the outer shell is also made of engineering plastic. They are tightly connected to the base by adhesive bonding to protect the internal components of the ultrasonic acupuncture head.

[0014] Furthermore, the attached soft sleeve includes a soft sleeve and double-sided adhesive that is pasted onto the lip of the soft sleeve, and the soft sleeve is made of an elastic material.

[0015] Furthermore, the driver includes a driver housing, inside which a transducer driver module and a power module are arranged in sequence. An operation and display module is provided on the upper surface of the driver housing, a power socket is provided on the front side, and a power switch and a connector are provided on the left and right sides respectively.

[0016] The beneficial effects achieved by this invention are as follows: This acupuncture device solves the defect that traditional handheld ultrasonic acupuncture devices cannot treat multiple acupoints at the same time, and also solves the problem of fixed sound field and single stimulation mode of traditional adhesive ultrasonic therapy instruments. This acupuncture device can flexibly select acupoints, treat multiple acupoints at the same time, and control the sound field to implement twisting and sedation and lifting and inserting treatment techniques, so that the therapeutic effect of ultrasonic acupuncture is closer to the effect of traditional filiform needle acupuncture.

Detailed Implementation

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example 1

[0029] like Figures 1-8 As shown, an adhesive ultrasonic acupuncture device includes an ultrasonic acupuncture head 100, which is nested within an adhesive soft sleeve 200, and is electrically connected to a driver 300.

[0030] The ultrasonic acupuncture head 100 is connected to the driver 300 via a cable 400 or via a connector thereon.

[0031] The ultrasonic acupuncture head 100 includes a base 101, which is sleeved with an ultrasonic transducer assembly 102. A thermistor 103 is provided on its upper surface, and a housing 104 is sleeved on top. The housing 104 has a cable outlet 105 for the cable 400 to pass through.

[0032] The base 101 is made of engineering plastics, such as ABS or PC, and meets biocompatibility requirements, allowing direct contact with human skin. The base 101 has at least one mounting hole for mounting at least one ultrasonic transducer assembly 102.

[0033] The ultrasonic transducer assembly 102 includes a mounting base 1022 and a piezoelectric element 1021 mounted therein. The piezoelectric element 1021 is a sheet-like piezoelectric ceramic (e.g., PZT piezoelectric ceramic) or a piezoelectric composite material (e.g., type 1-3 piezoelectric composite material). Extremely thin metal electrodes (e.g., silver plating) are attached to the upper and lower surfaces of the piezoelectric element 1021 and are connected to corresponding wires in the cable 400 by brazing. The mounting base 1022 is made of metal (e.g., SUS304 stainless steel) or engineering plastic (e.g., ABS, PC), is sheet-like, meets biocompatibility requirements, and can directly contact human skin. The piezoelectric element 1021 and the mounting base 1022 are tightly connected by adhesive bonding (e.g., using epoxy resin). The ultrasonic waves generated by the piezoelectric element 1021 can propagate into human tissue through the mounting base.

[0034] The thermistor 103 is bonded to the corresponding groove of the base 101 by thermally conductive silicone and is located next to the ultrasonic transducer assembly 102. It is connected to the corresponding wire in the cable 400 by brazing and is used to measure the temperature near the ultrasonic transducer assembly 102 to prevent the temperature from being too high and causing damage to human skin (safety regulations require that the temperature at this location must not exceed 41°C).

[0035] The outer shell 104 is made of engineering plastic (such as ABS, PC, etc.) and is tightly connected to the base 101 by adhesive bonding to protect the internal components of the ultrasonic acupuncture head 100.

[0036] The ultrasonic sound fields emitted by multiple piezoelectric elements 1021 are superimposed to form a needle-shaped composite sound field. By controlling the rotation mode and intensity changes of the sound field, the twisting and sedation techniques and lifting and thrusting techniques in acupuncture treatment can be simulated. The ultrasonic transducer assembly 102 is divided into ultrasonic transducer assembly 102-1 and ultrasonic transducer assembly 102-2. Each ultrasonic transducer assembly 102 can emit a center frequency of 3.0MHz and a sound power of 0.1W / cm². 2 ~3.0W / cm 2 Ultrasound.

[0037] The control process of the tonifying and reducing techniques and the lifting and thrusting techniques in simulated acupuncture treatment is as follows: Among multiple ultrasonic transducer components 102 evenly arranged in a circumferential direction, at a certain moment only a portion of the ultrasonic transducer components 102 vibrate, forming a needle-shaped composite ultrasonic field. At the next moment, another portion of the ultrasonic transducer components 102, rotated by a certain angle in the circumferential direction, vibrates, and the formed needle-shaped composite ultrasonic field also rotates by a set angle in the circumferential direction. For example, in this preferred embodiment, ultrasonic transducer component #1 includes the vibration of ultrasonic transducer component 102-1 and ultrasonic transducer component #2 102-2, forming a needle-shaped composite ultrasonic field (center frequency 3.0MHz, sound power 0.2W / cm²). 2 ~3.0W / cm 2 In the next instant, ultrasonic transducer assembly 102-1 and ultrasonic transducer assembly 3 vibrate, and the resulting needle-shaped composite ultrasonic field rotates 45°. In the next instant after that, ultrasonic transducer assembly 202-2 and ultrasonic transducer assembly 3 vibrate, and the resulting needle-shaped composite ultrasonic field rotates another 45°. This cycle of vibration of the ultrasonic transducer assembly 102 continues, and the needle-shaped composite ultrasonic field rotates at a certain speed. Through a control program, the rotation speed and direction of the needle-shaped composite ultrasonic field can be changed, thereby simulating the twisting and tonifying techniques in acupuncture treatment. The intensity of the needle-shaped composite ultrasonic field (sound power 0.2W / cm²) can also be changed. 2 ~3.0W / cm 2 The presence or absence of these elements are used to simulate the lifting and thrusting techniques in acupuncture treatment.

[0038] The soft sleeve 200 includes a soft sleeve 201 and double-sided adhesive 202 adhered to the lip of the soft sleeve 201. The soft sleeve 201 is made of an elastic material (e.g., silicone rubber, nitrile rubber, polyurethane rubber, etc.), meets biocompatibility requirements, and can come into direct contact with human skin. The double-sided adhesive 202 is a biocompatibility-compliant medical double-sided adhesive.

[0039] When performing acupuncture treatment, first insert the ultrasonic acupuncture head 100 into the groove of the adhesive soft sleeve 200, apply ultrasonic coupling agent to the surface of the ultrasonic acupuncture head 100 (to eliminate air between the ultrasonic acupuncture head and the skin), peel off the release paper on the surface of the double-sided adhesive, align the ultrasonic acupuncture head 100 with the acupoint to be treated, stick the lip of the adhesive soft sleeve to the skin near the acupoint, and fix the ultrasonic acupuncture head 100 on the acupoint.

[0040] The driver 300 includes a driver housing 307, in which a transducer driver module 301 and a power module 302 are arranged in sequence. An operation and display module 303 is arranged on its upper surface, a power socket 305 is arranged on the front side, and a power switch 304 and a connector 306 are arranged on its left and right sides respectively.

[0041] The power socket 305 is connected to the cable 400, which can be connected to the mains power to power the driver or to charge the lithium-ion battery in the power module.

[0042] Users can set the stimulation intensity, rotation speed and direction of the twisting and purging technique, speed of the lifting and thrusting operation, treatment time, etc. through the operation and display module 303.

[0043] The transducer drive module 301, based on the parameters set by the user, controls the frequency synthesis chip via the main control microcontroller to provide drive signals to the power amplifier circuit. It also adjusts the input voltage of the power amplifier circuit to change its output power. Through connector 306 and cable 400, it outputs drive signals to the ultrasonic transducer assembly 102 attached to the acupoint, exciting the ultrasonic transducer assembly 102 to emit a center frequency of 3MHz and a sound power of 0.1W / cm². 2 ~3.0W / cm 2 The transducer uses pulsed ultrasound waves to perform ultrasonic acupuncture treatment. The no-load protection circuit built into the transducer drive module 301 can sample the voltage value between the upper and lower electrodes of the ultrasonic transducer in real time. If there is an air gap between the ultrasonic transducer assembly 102 and the human skin, the ultrasonic transducer will heat up and cause the voltage between the electrodes to increase. After the no-load protection circuit detects the increased abnormal voltage, the transducer drive module 301 will stop outputting the drive signal and issue an alarm message in the control and display module to indicate abnormal contact.
