Description

Technical Field

[0001] This utility model relates to the field of mechanical pulse technology, specifically to a handheld device for joint frequency-modulated vibration therapy. Background Technology

[0002] Spinal disorders are caused by changes in the bones, intervertebral discs, muscles, and ligaments of the spine, which irritate the spinal cord and spinal nerves, resulting in symptoms. Cervical spondylosis and lumbar spondylosis are the most common. Symptoms often include neck and shoulder pain, headaches, dizziness, lumbosacral pain, and even radiating pain to the lower limbs, making it difficult to stand upright. In severe cases, it can lead to paralysis, negatively impacting the patient's quality of life.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0030] This embodiment relates to a handheld device for joint frequency-modulated vibration therapy, referring to... Figures 1-4The system includes a probe 100, a handle body 200, and a main body base 300. The handle body 200 includes a first sensor 210, one end of which is inserted into the probe 100; a connecting component; a vibration component; a detection component; and a fixing base 250. One end of the connecting component abuts against the end of the first sensor 210 away from the probe 100, and the other end is inserted into one end of the vibration component. One end of the fixing base 250 is fitted inside the main body base 300, and the other end is fitted to the end of the vibration component away from the connecting component. The detection component is fitted inside the end of the fixing base 250 away from the vibration component. A test piece 410 that mates with the detection component is disposed on the side of the main body base 300 facing the detection component. The probe 100, the first sensor 210, the detection component, and the vibration component are electrically connected. The handle body 200 also includes an outer sleeve. The outer sleeve is fitted around one end of the first sensor 210 and the outer periphery of the vibration component, and one end is fitted onto the side of the main body base 300 facing the vibration component. The outer sleeve has a heat dissipation structure. This handheld joint variable frequency vibration therapy device uses a probe 100 to contact the area of ​​the patient requiring treatment. Data detected by the first sensor 210 is fed back to an external control terminal, which then determines the appropriate mechanical vibration pulse frequency for treatment. This allows for individualized treatment tailored to different needs, resulting in good therapeutic effects. Specifically, when the probe 100 contacts the area, it experiences a pushing force towards the first sensor 210. This pushes the first sensor 210, the connecting assembly, the vibration assembly, the detection assembly, and the mounting base 250 towards the main body 300, enabling the detection assembly to detect the measured component 410. This establishes a circuit connection between the probe 100, the first sensor 210, the detection assembly, and the vibration assembly, allowing the vibration assembly to receive vibration frequency commands from the control terminal. The handheld joint variable frequency vibration therapy device connects to an external control terminal, which is a conventional control device. Furthermore, the outer sleeve of the handheld device incorporates a heat dissipation structure to effectively dissipate heat generated during operation, ensuring stable data output and preventing instability and sensitivity reduction caused by localized overheating. This handheld device for joint frequency-modulated vibration therapy has the advantages of good heat dissipation, high detection sensitivity, and stable detection.

[0031] In this embodiment, a shock-absorbing soft rubber sleeve is provided around one end of the probe 100 that is inserted into the first sensor 210. This sleeve is located between one end of the probe 100 and the first sensor 210, and the surface of the shock-absorbing soft rubber has an integrally formed annular protrusion to facilitate an interference fit with the first sensor 210 and prevent the probe 100 from detaching from the first sensor 210. The other end of the probe 100 is semi-circular. The first sensor 210 is a conventional piezoelectric quartz force sensor. It mainly utilizes the piezoelectric effect of quartz crystals to convert force into charge. The charge generated by the sensor is proportional to the measured external force. The charge is then converted into voltage by a charge amplifier, and its magnitude and change are read using a voltmeter or other display. The piezoelectric quartz force sensor consists of a base, a top cover, a quartz crystal, electrodes, and lead-out sockets. In this embodiment, the first sensor 210 is an integrated sensor, which facilitates installation and prevents tampering. Furthermore, the first sensor 210 uses a 500W coaxial cable for stable output, making it less prone to damage; the first sensor 210 has a built-in circuit board with potting encapsulation, making it tamper-proof, stable in performance, and reliable in detection. In some embodiments, the first sensor 210 can also be other piezoelectric sensors.

[0032] In this embodiment, refer to Figure 3 as well as Figure 5 The outer sleeve includes a first sleeve 271 and a second sleeve 272. The first sleeve 271 is fitted onto the outer periphery of the first sensor 210 and the vibration component at one end, and is mounted on the main body 300 facing the vibration component at the other end. The second sleeve 272 is located between the first sleeve 271 and the vibration component, and is embedded in the inner wall of the first sleeve 271. The heat dissipation structure includes a heat dissipation groove 2721 formed on the inner wall of the second sleeve 272 and a heat dissipation hole 2711 formed on the first sleeve 271. The first sleeve 271 and the second sleeve 272 protect the internal components of the handle body 200 and have cavities for assembling other components. The heat dissipation groove 2721 and the heat dissipation hole 2711 effectively dissipate the heat generated during the operation of the vibration component. Furthermore, multiple heat dissipation grooves 2721 are provided and are arranged circumferentially on the inner wall of the second sleeve 272. Multiple heat dissipation holes 2711 are provided and are arranged circumferentially on the first sleeve 271. The circumferential arrangement of multiple heat dissipation slots 2721 and multiple heat dissipation holes 2711 can effectively accelerate heat dissipation.

[0033] Furthermore, referring to Figures 3-4 as well as Figure 7The vibration assembly includes: a vibration mounting base 231, a coil winding base 232, a coil (not shown in the attached diagram), and a vibration block 233. One end of the vibration mounting base 231 is mounted on one end of a fixed base 250; the coil winding base 232 is mounted inside the vibration mounting base 231, with one end located between one end of the vibration mounting base 231 and one end of the fixed base 250. The coil winding base 232 has a cavity communicating with one end of the fixed base 250. The coil is disposed on the side of the coil winding base 232 near the first sensor 210. One end of the vibration block 233 is mounted inside the cavity, and the other end is mounted inside one end of the fixed base 250. The vibration mounting base 231 has a through hole 2312 at the end facing the first sensor 210 for one end of a connecting assembly to pass through; one end of the vibration block 233 has a slot 2331 corresponding to the through hole 2312 for insertion of one end of the connecting assembly; the coil, the first sensor 210, and the detection assembly are electrically connected. Specifically, the vibration mounting base 231, the coil winding base 232, and one end of the fixing base 250 are fixed with screws to ensure the stability of the structure. The coil is wound on the side of the coil winding base 232 near the first sensor 210. After the circuit is turned on, the vibration block 233 achieves efficient and controllable vibration output through the electromagnetic induction effect with the coil. The through hole 2312 and the slot 2331 facilitate a secure connection between the connecting components and the vibration block 233.

[0034] In this embodiment, the vibrating block 233 is a vibrating magnet. In some embodiments, the vibrating block 233 may also be other magnetic devices capable of generating electromagnetic induction effects with the coil.

[0035] Furthermore, the vibration assembly also includes a balancer 234 mounted on the end of the vibration block 233 near the detection assembly. The balancer 234 is used to prevent the vibration block 233 from wobbling radially. The balancer 234 can effectively ensure that the vibration block 233 vibrates axially during the vibration process, avoiding left and right wobbling, making the handheld detection of this joint frequency-modulated vibration therapy more stable, the operation more stable, and the structure more compact.

[0036] In this embodiment, refer to Figures 3-4The connecting assembly includes a connecting shaft 221 and a first connecting flexible member 222. One end of the connecting shaft 221 passes through a through hole 2312 and is inserted into a slot 2331. One side of the first connecting flexible member 222 abuts against the first sensor 210, and the other side abuts against the other end of the connecting shaft 221. One end of the connecting shaft 221 is stably connected to the vibration block 233. The first connecting flexible member 222 is used to prevent the other end of the connecting shaft 221 from directly impacting the first sensor 210, thus avoiding damage to the first sensor 210 during vibration and serving as a buffer and protector for the first sensor 210. In this embodiment, the connecting shaft 221 is configured as a connecting pin, and the first connecting flexible member 222 is configured as a soft rubber with relatively high hardness. In some embodiments, the connecting shaft 221 may also be other connecting components, and the first connecting flexible member 222 may also be a plastic block.

[0037] Furthermore, referring to Figure 3 as well as Figures 6-7 The handle body 200 also includes a second flexible connecting member 223. One end of the second flexible connecting member 223 is fitted onto the outer periphery of the first sensor 210 near the end of the connecting assembly; the other end of the second flexible connecting member 223 is located between the vibration mounting base 231 and one end of the connecting assembly, and a first protrusion 2231 extending toward the vibration mounting base 231 is provided on its outer wall; a limiting groove 2311 that mates with the first protrusion 2231 is provided on the vibration mounting base 231. Specifically, the second flexible connecting member 223 is sleeved on the outer periphery of one end of the first sensor 210 and one end of the connecting assembly; one end is threaded to the outer periphery of the first sensor 210 near the end of the connecting assembly, and the other end is located between the vibration mounting base 231 and one end of the connecting assembly, and a first protrusion 2231 extending toward the vibration mounting base 231 is provided on its outer wall, which serves to ensure that the first sensor 210 can be stably abutted against the connecting assembly. The engagement between the first protrusion 2231 and the limiting groove 2311 ensures the fixed assembly position of the second connecting flexible member 223, facilitating the guidance of the wiring path and preventing rotation of the second connecting flexible member 223 from affecting the overall wiring of the handheld end of the joint's frequency conversion vibration therapy. In this embodiment, the second connecting flexible member 223 is made of plastic. In some embodiments, the second connecting flexible member 223 may also be made of silicone.

[0038] Furthermore, the handle body 200 also includes an O-ring 260, which is sleeved on the outside of the connecting shaft 221, with one side abutting against the second connecting flexible member 223 and the other side abutting against the vibration mounting base 231, thereby further providing a buffering effect.

[0039] In this embodiment, refer to Figure 3 as well as Figures 6-7The handle body 200 also includes a front sleeve 280. One end of the front sleeve 280 is located between the second connecting flexible member 223 and the vibration mounting base 231, and is mounted on the vibration mounting base 231; the other end of the front sleeve 280 is sleeved on the outside of the end of the first sensor 210 where the probe 100 is inserted; the front sleeve 280 is provided with a second protrusion 281 that mates with the limiting groove 2311. The front sleeve 280 is made of existing POM material with self-lubricating properties. The second protrusion 281 mates with the limiting groove 2311 to facilitate the installation of the front sleeve 280.

[0040] In some embodiments, the handle body 200 further includes: a first elastic reset member 291, a second elastic reset member 292, and a third elastic reset member 293. The first elastic reset member 291 is located inside the front sleeve 280 and sleeved on the outer periphery of the first sensor 210, with both ends abutting against the inner wall of the front sleeve 280 and the outer wall of the first sensor 210, respectively, and its function is to reset. The second elastic reset member 292 is located inside the main body 300, with both ends abutting against one end of the fixed base 250 and the inner wall of the main body 300, respectively, and the second elastic reset member 292 serves a shock-absorbing and buffering function. The third elastic reset member 293 is located inside the main body 300 and sleeved on the outer periphery of the measured component 410, with one end abutting against one end of the fixed base 250 and the other end abutting against the inner wall of the main body 300. The third elastic reset member 293 serves a buffering, shock-absorbing, and resetting function. Specifically, the first elastic reset member 291, the second elastic reset member 292, and the third elastic reset member 293 are all springs. In other embodiments, the first elastic reset member 291, the second elastic reset member 292, and the third elastic reset member 293 may also be other elastic and resetting devices.

In other embodiments, the second sensor 242 can also be other photoelectric sensors. Specifically, the control circuit board 241 is externally connected to a 9-core cable, one of which is a coaxial cable 500, which transmits signals to a control terminal. The coaxial cable 500 provides stable transmission and is not easily interfered with. The control terminal provides feedback commands, and the control circuit board 241 adjusts the vibration frequency of the vibrating block 233. The cable 500 is securely mounted to the mounting base 250 using fasteners.

[0042] In some embodiments, the outer side of the main body 300 is fitted with a flexible outer sleeve 420 to facilitate gripping and appropriately reduce vibration in the operator's hand.

[0043] The working principle of this utility model is roughly as follows: When the probe 100 contacts the patient, it pushes the first sensor 210 to move towards the main body 300, i.e., backward. The first sensor 210 drives the connecting assembly, vibration assembly, detection assembly, and fixing base 250 to move towards the main body 300. At this time, the tested component 410 passes through the second sensor 242, triggering it. The conduction of the second sensor 242 enables the conduction of the entire circuit, energizing the coil and driving the vibration block 233 to vibrate and impact the vibration mounting base 231. During this process, the probe 100, connected to the first sensor 210, detects the tension and feeds it back to the control circuit board 241. The control circuit board 241 adjusts the vibration frequency of the vibration block 233, which is then transmitted to the surface of the object being acted upon through the probe 100. This joint frequency conversion vibration therapy handheld device has the advantages of stable detection, high sensitivity, stable operation, low noise, compact structure, and good heat dissipation.
