Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, specifically to a handle extraction sensing device and an ultrasonic therapy device equipped with the handle extraction sensing device. Background Technology
[0002] An ultrasound therapy device typically includes a frame, a main unit, a handpiece, and an ultrasound treatment head. The main unit is mounted on the frame, the handpiece is electrically connected to the main unit, and the ultrasound treatment head is mounted on the head of the handpiece and connected to it. To facilitate the storage and retrieval of the handpiece, a storage bracket is usually provided on the main unit or the frame. Furthermore, to meet different treatment needs and improve the practicality of the ultrasound therapy device, some existing ultrasound therapy devices are equipped with two or more handpieces and ultrasound treatment heads to perform different functions and / or treat different treatment areas.
[0003] Since different handles and ultrasonic treatment heads are used during the actual use of the ultrasonic therapy device, in order for the main unit to facilitate the control of the handles and ultrasonic treatment heads (such as identifying the used handles and ultrasonic treatment heads to switch to the control program and related working parameters, and identifying the unused handles and ultrasonic treatment heads to control them to be in a stopped working state or standby state, etc.), the device will detect whether the handle has been removed from the storage bracket. This allows the main unit to switch to the relevant control program that matches the currently used handle and ultrasonic treatment head based on the detection result, thereby making the use of the ultrasonic therapy device more intelligent and improving the user experience.
[0004] The existing method for detecting whether a handle has been retrieved involves placing a Hall effect sensor electrically connected to the host on a storage bracket, and placing a magnet inside the handle. When the handle is placed on the storage bracket, the magnet inside the handle is aligned with the Hall effect sensor on the bracket. The host then uses the feedback signal from the Hall effect sensor to determine that the handle has not been retrieved. When the handle is removed from the storage bracket, the host uses the feedback signal from the Hall effect sensor to determine that the handle has been retrieved. However, this method has drawbacks: each time the handle is placed on the storage bracket, the relative position of the handle and the bracket generally needs to be manually adjusted to ensure that the magnet inside the handle is within the detection range of the Hall effect sensor. This results in a long adjustment time, high placement requirements, and a poor user experience. This is especially true for cylindrical handles, where the orientation of the magnet is more difficult to determine after placement, requiring even more time to adjust the handle's position. Summary of the Invention
[0005] To address the aforementioned problems, the main objective of this invention is to provide a handle extraction sensing device that requires no adjustment of the handle's placement and boasts high detection accuracy.
[0006] Another objective of this invention is to provide an ultrasonic therapy device equipped with the aforementioned handle extraction sensing device.
[0007] To achieve the main objective of this utility model, it provides a handle extraction sensing device, including a storage bracket and a handle. The storage bracket has a storage limiting cavity extending through the height of the storage bracket. The handle is detachably inserted into the storage limiting cavity. A magnet assembly is mounted on the storage bracket and arranged circumferentially around the storage limiting cavity. The central angle of the magnet assembly around the storage limiting cavity is between 170° and 360°. The handle contains a control module and two magnetic sensing elements, which are located on opposite sides of the handle. The magnetic sensing elements are electrically connected to the control module. When the handle is placed in the storage limiting cavity, the magnet assembly surrounds at least one magnetic sensing element.
[0008] As can be seen from the above, the distribution of the magnet assembly, combined with the number and position of the magnetic sensing elements, ensures that when the handle is placed in the storage limiting cavity, regardless of the relative position of the handle and the storage bracket in the circumferential direction of the storage limiting cavity, at least one magnetic sensing element can detect the magnet assembly. This ensures that the main unit of the ultrasonic therapy device accurately determines whether the handle is placed on the storage bracket, and that the user does not need to manually adjust the orientation range of the handle after it is placed on the storage bracket, thus improving the detection efficiency of the magnetic sensing elements and the user experience. At the same time, since the magnet assembly is located on the storage bracket rather than inside the handle, it avoids interference from the magnetic field of the magnet assembly to other components on the control module, ensuring the stability and reliability of the handle and the ultrasonic therapy head installed on the handle.
[0009] A preferred design is that the storage and limiting cavity is roughly cylindrical or frustum-shaped, and the handle is roughly a rotating body.
[0010] As can be seen from the above, setting the handle as a rotating body can improve the user's comfort in holding the handle and avoid the user's hand feeling. Setting the storage limiting cavity as cylindrical or frustum-shaped allows the inner wall of the storage limiting cavity to better fit the surface of the support handle.
[0011] A further embodiment is that the magnet assembly includes multiple magnets that are closely distributed around the circumference of the storage limiting cavity; the storage bracket has multiple mounting slots in the circumference of the storage limiting cavity, and one magnet is installed in one mounting slot; the magnet is interference-fitted with the mounting slot and / or the magnet is fixedly connected to the mounting slot by an adhesive.
[0012] As can be seen above, dividing the magnet assembly into multiple closely distributed magnets makes the assembly between the magnet assembly and the storage bracket easier and reduces the chance of magnet damage during the assembly process.
[0013] Another further option is that the magnet assembly is fan-shaped, the storage bracket has a fan-shaped groove, the fan-shaped groove surrounds the storage limiting cavity in the circumferential direction, and the magnet assembly is installed in the fan-shaped groove; the magnet assembly and the fan-shaped groove are interference-fitted and / or the magnet assembly and the fan-shaped groove are fixedly connected by an adhesive.
[0014] As can be seen from the above, setting the magnet assembly in a fan-shaped ring can better ensure the continuity of the magnet assembly distribution and reduce the risk of missed detection or false detection by the magnetic sensing element.
[0015] Another further design is that the top of the receiving and limiting cavity has a variable diameter section, which is roughly in the shape of an inverted frustum; the head of the handle has a limiting section, which is roughly in the shape of an inverted frustum, and when the handle is placed in the receiving and limiting cavity, the limiting section is located inside the variable diameter section.
[0016] As can be seen from the above, the combination of the variable diameter section and the limiting section can limit the handle and prevent the handle from coming off the bottom of the storage bracket.
[0017] Another preferred option is that the magnetic sensing element is a Hall effect sensor, a reed switch sensor, a magnetic induction sensor, a magnetoresistive sensor, or a magnetic diode.
[0018] As can be seen from the above, the wide range of magnetic induction elements available allows users to select the appropriate type of magnetic induction element based on usage requirements, cost requirements, assembly requirements, and internal space layout of the handle, thereby improving the flexibility of handle extraction sensing device production.
[0019] A further solution is that the storage bracket has a connecting part and a storage part, with the connecting part extending from the side wall of the storage part toward the storage limiting cavity, and the storage limiting cavity being formed on the storage part.
[0020] As can be seen from the above, the design helps to optimize the structure of the storage bracket, reduce its volume, and make it easier to connect the storage bracket to external components (such as the main unit or frame of the ultrasonic therapy device).
[0021] A further improvement is that the storage section has two clearance notches, which are evenly distributed along the axial direction of the storage limiting cavity. The clearance notches penetrate the wall of the storage section and penetrate the top of the storage section in the height direction.
[0022] As can be seen above, the notch design allows users to more easily remove the handle from the storage holder and prevents their hands from touching the ultrasound treatment head during the removal process.
[0023] A further improvement is that one of the two clearance notches also extends through the bottom of the storage section in the height direction; the magnet assembly is located at the bottom of the storage section, and the central angle of the magnet assembly arranged around the storage limiting cavity is between 180° and 270°, and the magnetic induction element is located at the middle and rear of the handle.
[0024] As can be seen from the above, placing the magnet assembly at the bottom of the storage section and matching it with the magnetic induction element at the middle and rear of the handle can prevent the magnetic field generated by the magnet assembly from affecting the components of the control module and the ultrasonic treatment head inside the handle, thus ensuring that the control module and the ultrasonic treatment head can work stably and reliably.
[0025] To achieve another objective of this utility model, this utility model provides an ultrasonic therapy device, including a main unit and an ultrasonic therapy head, wherein the device further includes the aforementioned handle extraction sensing device, a control module electrically connected to the main unit, and the ultrasonic therapy head installed on the head of the handle and electrically connected to the control module; a storage bracket is installed on the main unit, or the ultrasonic therapy device further includes a frame, with both the main unit and the storage bracket installed on the frame.
[0026] As can be seen from the above, the ultrasonic therapy device equipped with the aforementioned handle extraction sensing device allows the main unit to accurately determine whether the handle is placed on the storage bracket without adjusting the relative position of the handle and the storage bracket in the circumferential direction of the storage limiting cavity. This enables the main unit to switch the relevant control program promptly and accurately when the handle is placed on or removed from the storage bracket, making it more convenient for users to use the ultrasonic therapy device to treat patients and improving the user experience.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation
[0032] First embodiment of handle extraction sensing device
[0033] Reference Figure 1 and Figure 2The handle extraction sensing device 100 includes a storage bracket 1 and a handle 2; wherein, the storage bracket 1 has a storage limiting cavity 121, and the storage limiting cavity 121 extends through the storage bracket 1 in the height direction, and the handle 2 is detachably inserted into the storage limiting cavity 121.
[0034] Combination Figure 3 In this embodiment, the storage bracket 1 has a connecting portion 11 and a storage portion 12. A storage limiting cavity 121 is formed on the storage portion 12, and the connecting portion 11 extends from the side wall of the storage portion 12 away from the storage limiting cavity 121. The connecting portion 11 can be used to connect external components (such as the main unit or frame of an ultrasonic therapy device), and the setting of the connecting portion 11 makes it easier to connect the storage bracket 1 to external components. It also helps to optimize the structure of the storage bracket 1 and reduce its volume. In addition, a magnet assembly 13 is installed on the storage portion 12 of the storage bracket 1. The magnet assembly 13 is arranged circumferentially around the storage limiting cavity 121, and the central angle of the magnet assembly 13 around the storage limiting cavity 121 is between 170° and 360°.
[0035] The handle 2 includes a housing 21, a control module 22, and two magnetic induction elements 23. The control module 22 and the two magnetic induction elements 23 are both installed inside the housing 21, and the two magnetic induction elements 23 are electrically connected to the control module 22. The two magnetic induction elements 23 are located on opposite sides of the handle 2, such that when the handle 2 is placed in the storage limiting cavity 121, the magnet assembly 13 surrounds the outer periphery of at least one magnetic induction element 23.
[0036] By strategically distributing the magnet components 13 in conjunction with the number and placement of the magnetic sensing elements 23, it is ensured that when the handle 2 is placed within the storage and limiting cavity 121, regardless of the relative position of the handle 2 and the storage support 1 in the circumferential direction of the storage and limiting cavity 121, at least one magnetic sensing element 23 will always detect the magnet components 13. This ensures that the main unit of the ultrasonic therapy device accurately determines whether the handle 2 is placed on the storage support 1, and eliminates the need for manual adjustment of the handle 2's orientation after placement, thus improving the detection efficiency of the magnetic sensing elements 23 and enhancing the user experience. Furthermore, since the magnet components 13 are located on the storage support 1 rather than within the handle 2, the magnetic field generated by the magnet components 13 avoids interference with other components on the control module 22, ensuring the stability and reliability of the handle 2 and the ultrasonic therapy head mounted on it.
[0037] In this embodiment, the storage and limiting cavity 121 is approximately frustum-shaped, and the handle 2 is approximately a rotating body. Setting the handle 2 as a rotating body improves the user's comfort in holding it, preventing a feeling of discomfort. Furthermore, setting the storage and limiting cavity 121 as frustum-shaped allows the inner wall of the cavity to better fit and support the surface of the handle 2, thus limiting the handle 2 and preventing it from slipping out of the bottom of the cavity. Of course, as another optional solution, the storage and limiting cavity 121 can also be approximately cylindrical.
[0038] Furthermore, a variable-diameter section 1211 can be formed at the top of the storage and limiting cavity 121, which is approximately frustum-shaped. Correspondingly, a limiting section 211 is formed at the head of the handle 2, which is also approximately frustum-shaped. This ensures that when the handle 2 is placed in the storage and limiting cavity 121, the limiting section 211 of the handle 2 is located within and conforms to the variable-diameter section 1211 of the storage and limiting cavity 121. Through the cooperation of the variable-diameter section 1211 and the limiting section 211, the handle 2 is limited, thereby better preventing the handle 2 from coming off the bottom of the storage bracket 1.
[0039] Furthermore, the magnet assembly 13 is preferably located at the bottom of the storage section 12, while the magnetic induction element 23 is preferably located at the middle and rear of the handle 2. By placing the magnet assembly 13 at the bottom of the storage section 12 and placing the magnetic induction element 23 at the middle and rear of the handle 2, the magnetic field generated by the magnet assembly 13 can be prevented from affecting the components of the control module 22 and the components of the ultrasonic treatment head inside the handle 2, ensuring that the control module 22 and the ultrasonic treatment head can work stably and reliably.
[0040] Furthermore, in this embodiment, the storage portion 12 of the storage bracket 1 has multiple mounting slots 122 arranged circumferentially around the storage limiting cavity 121, and the multiple mounting slots 122 are closely distributed. Correspondingly, the magnet assembly 13 includes multiple magnets 131, each magnet 131 is installed in one mounting slot 122, and the multiple magnets 131 are continuously and closely distributed around the storage limiting cavity 121. Since magnets 131 are usually brittle materials, by dividing the magnet assembly 13 into multiple closely distributed magnets 131, the assembly difficulty between the magnet assembly 13 and the storage bracket 1 can be reduced, and the probability of damage to the magnets 131 during assembly can be reduced. The magnets 131 and the mounting slots 122 are fixedly connected by an interference fit, and / or the magnets 131 and the mounting slots 122 are fixedly connected by an adhesive to ensure the tightness of the assembly between the magnets 131 and the mounting slots 122.
[0041] In some embodiments, the central angle of the magnet assembly 13 arranged around the storage limiting cavity 121 is between 180° and 270°, so as to reduce the number of magnets 131 or reduce the overall volume of the magnet assembly 13 while ensuring that at least one magnetic sensing element 23 can always detect the magnet assembly 13 after the handle 2 is placed on the storage bracket 1, thereby reducing the cost.
[0042] Furthermore, the receiving part 12 is provided with two clearance notches 123, which are evenly distributed along the axial direction of the receiving and limiting cavity 121. The clearance notches 123 penetrate the wall of the receiving part 12 and penetrate the top of the receiving part 12 in the height direction. The clearance notches 123 make it easier for the user to remove the handle 2 from the receiving bracket 1 and prevent the user's hand from touching the ultrasonic treatment head during the removal process.
[0043] In some embodiments, one of the two clearance notches 123 also penetrates the bottom of the storage part 12 in the height direction, so that the storage part 12 can have a certain elastic deformation capability, so that when the handle 2 is placed on the storage bracket 1, the storage part 12 can act like a clamp to apply a certain clamping force to the handle 2, thereby better preventing the handle 2 from falling off the storage bracket 1 when not in use.
[0044] In addition, the magnetic sensing element 23 can be a Hall effect sensor, a reed switch sensor, a magnetic induction sensor, a magnetoresistive sensor, or a magnetic diode. As can be seen, the magnetic sensing element 23 offers a wide range of choices, allowing users to select the appropriate type of magnetic sensing element 23 based on usage requirements, cost requirements, assembly requirements, and the internal space layout of the handle 2, thereby improving the production flexibility of the handle extraction sensing device 100.
[0045] In summary, by designing the handle extraction sensing device 100, once the handle 2 is placed on the storage bracket 1, the magnetic sensing element 23 can detect the magnet component 13 without the user needing to adjust the placement of the handle 2, thus improving the user experience.
[0046] Second embodiment of handle extraction sensing device
[0047] Reference Figure 4 The difference between this embodiment and the first embodiment of the handle extraction sensing device lies in the shape of the magnet assembly and the shape of the groove on the storage part of the storage bracket that mates with the magnet assembly. Specifically, in this embodiment:
[0048] Instead of multiple magnets, the magnet assembly 31 is arranged in a fan-shaped ring. Correspondingly, the storage part 32 of the storage bracket no longer has multiple mounting slots, but instead uses a fan-shaped ring groove 321. The fan-shaped ring groove 321 surrounds the circumference of the storage limiting cavity, and the central angle of the fan-shaped ring groove 321 is preferably equal to or slightly larger than the central angle of the fan-shaped magnet assembly 31. It is understood that when the magnet assembly 31 is assembled with the storage part 32 of the storage bracket, the fan-shaped magnet assembly 31 is installed into the fan-shaped ring groove 321 of the storage part 32. Similarly, the magnet assembly 31 and the fan-shaped ring groove 321 are fixedly connected by an interference fit, and / or, the magnet assembly 31 and the fan-shaped ring groove 321 are fixedly connected by an adhesive.
[0049] Arranging the magnet assembly 31 in a fan-shaped ring shape better ensures the continuity of its distribution, reducing the risk of missed or false detections by the magnetic sensing element. Furthermore, as a single unit, the fan-shaped magnet assembly 31 provides a more uniform and continuous magnetic field compared to multiple separate magnets. When the handle is placed within the storage and limiting cavity, the uniform magnetic field ensures that the magnetic field strength surrounding at least one magnetic sensing element remains relatively stable. For example, during sensing, differences in magnetic field strength between multiple magnets or sudden changes in magnetic field at junctions will not affect the accuracy of the sensing, facilitating precise triggering of the magnetic sensing element.
[0050] Apart from the differences mentioned above, the other parts of this embodiment are the same as those of the first embodiment of the handle extraction sensing device, so they will not be described again here.
[0051] Example of an ultrasound therapy device
[0052] The ultrasonic therapy device includes a main unit, an ultrasonic therapy head, and the handle extraction sensing device described in the first or second embodiment. A control module is electrically connected to the main unit, and the ultrasonic therapy head is mounted on the head of the handle and electrically connected to the control module. A storage bracket is mounted on the main unit; alternatively, the ultrasonic therapy device also includes a frame, with both the main unit and the storage bracket mounted on the frame.
[0053] By incorporating the aforementioned handle extraction sensing device, the ultrasonic therapy device allows the main unit to accurately determine whether the handle is placed on the storage bracket without adjusting the relative position of the handle and the storage bracket in the circumferential direction of the storage limiting cavity. This enables the main unit to promptly and accurately switch relevant control programs when the handle is placed on or removed from the storage bracket, making it more convenient for users to treat patients with the ultrasonic therapy device and improving the user experience.
[0054] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications.
