Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing, specifically to a low-intensity pulsed ultrasound therapy device. Background Technology

[0002] Avascular necrosis of the femoral head is a common cause of hip pain and dysfunction. Especially since the invention and widespread use of glucocorticoids, long-term or excessive use of glucocorticoids has become the leading cause of this disease. Compared to other types of avascular necrosis of the femoral head, patients with hormone-induced avascular necrosis generally have a younger age of onset, and most are still in the working age. Younger patients not only face the adverse effects of a long disease progression, but also need to consider how to better protect joint function in the early and middle stages of the disease to avoid premature loss of working ability, as well as the durability of artificial hip joint prostheses and the additional risks of multiple revisions.

[0003] It is generally believed that insufficient local tissue blood supply is the main factor leading to the occurrence and development of femoral head necrosis. Related studies have confirmed that appropriate mechanical stimulation can effectively promote VEGF (vascular endothelial growth factor) metabolism by activating mechanical ion channels, promote osteoblast and H-microvascular production, thereby improving the blood supply to the femoral head and enhancing osteogenic differentiation, and has a good therapeutic effect on joint protection for patients with early and middle stage femoral head necrosis.

[0004] Low-intensity pulsed ultrasound (LIPUS) is a novel therapeutic ultrasound characterized by high energy density, strong penetration, and high safety. Its high energy density is precisely adjustable and controllable, resulting in higher treatment accuracy, a wider range of suitable patients, and fewer side effects. Compared to traditional high-intensity focused ultrasound (HIFU), LIPUS offers excellent mechanical effects while minimizing tissue thermal effects. Compared to extracorporeal shock-wave therapy (ESWT), LIPUS has lower single-pulse energy but a higher repetition rate, with precisely controllable emission energy, leading to higher treatment safety and a broader range of suitable patients.

[0005] Currently, extracorporeal shock wave therapy is used for physical therapy of avascular necrosis of the femoral head and related diseases. Such equipment is expensive, bulky, and requires professional operation. Patients need to be hospitalized for treatment. Moreover, this treatment is only effective for patients in the middle and late stages. It is inconvenient for patients with mid-to-late stage avascular necrosis of the femoral head who have difficulty walking. In addition, the pain during the treatment is strong, and the shock wave energy often becomes out of focus due to the patient's body movement. All these shortcomings lead to poor compliance and poor clinical results of this type of treatment.

[0006] Therefore, there is an urgent need for a physical therapy device with potential for home use, as well as greater safety and portability, enabling patients with avascular necrosis of the femoral head to receive convenient and effective self-treatment. Studies have shown that low-intensity pulsed ultrasound therapy has demonstrated positive therapeutic effects in promoting VEGF and H-microvascular angiogenesis. In addition, low-intensity pulsed ultrasound also has advantages such as small device size, precisely adjustable parameters, and convenient and quick use. Based on these advantages, this invention proposes a wearable low-intensity pulsed ultrasound therapy device and its application in avascular necrosis of the femoral head and related diseases. Utility Model Content

[0007] Through structural improvements, this invention enables the low-intensity pulsed ultrasound therapy device to more effectively address the portable home treatment needs of avascular necrosis of the femoral head.

[0008] To achieve the objective of this utility model, the technical solution adopted is as follows: A low-intensity pulsed ultrasound therapy device, comprising: A housing containing several pulsed ultrasonic generators connected to a controller, arranged side by side. A water bag with sound transmission function is attached to the ultrasonic energy output surface of the pulse ultrasound generator. The ultrasonic energy is transmitted to the human body through the water bag, forming an energy transmission channel. The housing is installed via a flexible strap and a housing mounting surface cut to fit the shape of the housing on a flexible fastener; The pulsed ultrasound generator and the water bladder inside the housing are integrated and assembled at the mounting surface of the housing. The flexible fixation member has adhesive surfaces along its edges. By bonding or detaching the different adhesive surfaces, the flexible fixation member can be attached to the user's treatment area to form a flexible treatment restraint cavity.

[0009] In a preferred embodiment of this utility model, the flexible fastener is a first flexible fastener and a second flexible fastener that are attached to each other; The first protruding end of the first flexible fastener is attached to the first protruding end of the second flexible fastener; The second protruding end of the first flexible fixation member and the second protruding end of the second flexible fixation member are attached to each other to form the flexible treatment restraint cavity.

[0010] In a preferred embodiment of this invention, the pulsed ultrasound generator has a frequency greater than 20 kHz and less than 20 MHz, and a spatial intensity greater than 0.1 W / cm². 2 And less than 3W / cm 2 .

[0011] In a preferred embodiment of this utility model, the thickness of the water bladder ranges from 0.1 mm to 0.15 mm.

[0012] In a preferred embodiment of this invention, the temperature of the water bladder is controlled by a heating control device connected to the controller.

[0013] In a preferred embodiment of this utility model, the controller is provided with a human-machine interface, which is used by the user to input the power-off command, power-on command, power-on confirmation command, and parameter adjustment command of the ultrasound therapy device; the parameters include at least the frequency and spatial intensity of the low-intensity pulse ultrasound and the temperature of the water bag.

[0014] In a preferred embodiment of this utility model, the controller is provided with a display, through which the power-off command, power-on command, power-on confirmation command, and parameter adjustment command are displayed and confirmed.

[0015] The beneficial effects of this utility model are as follows: This invention provides a device for treating femoral head necrosis using low-intensity pulsed ultrasound instead of traditional external shock waves. The device effectively provides mechanical stimulation to the femoral head tissue and cells. It is also small, portable, and easy to use, enabling patients to treat themselves at home.

[0016] This invention combines a low-intensity pulsed ultrasound generator with a water-filled bladder and fixes it within a flexible fixation component. In use, the device is wrapped and secured around the patient's hip and groin area, aligning the water-filled bladder with the treatment site and adhering tightly to the skin. The tension generated by the deformation of the flexible fixation component compresses the water-filled bladder, creating an effective restraint and generating a highly efficient energy transmission channel, enhancing therapeutic function. Furthermore, the flexible treatment restraint cavity formed by the flexible fixation component can adapt to different users and different treatment sites, allowing the energy transmission channel to better conform to the treatment area.

Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figure 1-3 The low-intensity pulsed ultrasound therapy device shown includes, for example: Figure 3 The housing 1 shown contains several pulse ultrasound generators 11 arranged side-by-side, each connected to a controller 4. These pulse ultrasound generators 11 generate low-intensity pulse ultrasound waves. The low-intensity pulse ultrasound waves generated by the pulse ultrasound generators have a frequency greater than 20 kHz and less than 20 MHz, and a spatial intensity greater than 0.1 W / cm². 2 And less than 3W / cm 2 .

[0023] A pulse transmission channel composed of water bladders 12 is arranged on the pulse output channel of the pulse ultrasound generator 1. It should be noted that the surface area 121 of the water bladders 12 after being filled needs to cover the area 111 of the pulse output channel of the pulse ultrasound generator 11. This facilitates the transmission of low-intensity pulse ultrasound.

[0024] The thickness of the water bladder ranges from 0.1mm to 0.15mm. This thickness range facilitates the stable transmission of low-intensity pulsed ultrasound.

[0025] The temperature of the water bladder 12 is controlled by a heating control device (not shown in the figure) connected to the controller 4.

[0026] The heating control device here can be any commercially available flexible heating control device.

[0027] The controller 4 is equipped with a human-machine interface 41, which is used by the user to input the power-off command, power-on command, power-on confirmation command and parameter adjustment command of the ultrasound therapy device; the parameters include at least the adjustment of the frequency and spatial intensity of the low-intensity pulse ultrasound and the temperature of the water bag.

[0028] The controller 4 is equipped with a display 42, which displays and confirms power-off commands, power-on commands, power-on confirmation commands, and parameter adjustment commands.

[0029] The shell 1 is installed on the outside of the shell by means of the flexible strip 2 and the shell mounting surface 301 cut on the flexible fastener 3 to match the shape of the shell 1.

[0030] The pulsed ultrasonic generator 11 and water bladder 12 inside the housing 1 are integrated and assembled at the housing mounting surface 301. The fixed position of the upper and lower assembly is controlled by the secondary restraint of the housing 1 and the flexible belt 2.

[0031] The edge of the flexible fixation member 3 is provided with an adhesive surface. By bonding or detaching the different adhesive surfaces, the flexible fixation member 3 is attached to the user's treatment site to form a flexible treatment restraint cavity.

[0032] Specifically, the flexible fastener 3 consists of a first flexible fastener 31 and a second flexible fastener 32 that are attached to each other, with the first protruding end 311 of the first flexible fastener 31 and the first protruding end 321 of the second flexible fastener 32 being attached to each other.

[0033] The second protruding end 312 of the first flexible fixation member 31 and the second protruding end 322 of the second flexible fixation member 32 are attached to each other to form a flexible treatment restraint cavity.

[0034] The width of the flexible treatment restraint cavity can be adjusted by changing the attachment angle and depth.

[0035] Because of the above structure, the working principle of this utility model is as follows: After powering on, the frequency and spatial intensity of the low-intensity pulse ultrasound and the temperature of the water bladder are adjusted according to the parameters set by the human-machine interface 41 of the controller 4, in order to meet the needs of different users.

[0036] The width of the flexible treatment confinement cavity is adjusted according to different treatment sites, so that the lower end of the water balloon is attached to the treatment area of ​​the patient and the low-intensity pulse ultrasound is effectively transmitted.

[0037] This invention combines a low-intensity pulsed ultrasound generator with a water-filled bladder and fixes it within a flexible fixation component. In use, the device is wrapped and secured around the patient's hip and groin area, aligning the water-filled bladder with the treatment site and adhering tightly to the skin. The tension generated by the deformation of the flexible fixation component compresses the water-filled bladder, creating an effective restraint and generating a highly efficient energy transmission channel, enhancing therapeutic function. Furthermore, the flexible treatment restraint cavity formed by the flexible fixation component can adapt to different users and different treatment sites, allowing the energy transmission channel to better conform to the treatment area.

[0038] The above shows and describes the basic principles, main features, and advantages of this utility model.

[0039] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
