Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a treatment head. Background Technology

[0002] The treatment head, used in conjunction with the main unit, enables ultrasound therapy, ultrasound-guided drug delivery, electromyographic biofeedback electrical stimulation, and heat therapy. These functions are of significant importance in the medical field, as detailed below:

[0003] Ultrasound therapy is a deep-penetrating thermotherapy method that can penetrate deep into muscles, promote blood circulation, accelerate wound healing, relieve fatigued muscles and ligaments, and effectively alleviate pain by affecting the nervous system. It is suitable for a variety of conditions, including chronic soft tissue injuries, arthritis, and rheumatism.

[0004] Electromyographic biofeedback electrical stimulation collects weak signals through electrodes on the patient's limb surface. After filtering, the signals expressing the patient's spontaneous electromyography (EMG) and muscle strength are extracted. Based on the magnitude of the EMG feedback, electrical stimulation of the same intensity is output synchronously. This stimulates the muscles in specific limb areas to perform contraction and extension movements, thereby training the voluntary motor function of the paralyzed limb.

[0005] Ultrasound-guided drug delivery therapy uses ultrasound technology to promote the penetration of drugs through the skin and other tissues into the body to achieve therapeutic effects.

[0006] However, existing treatment heads have some limitations. The suction bowl attached to the treatment head is an integral part of the housing, and the fixed structure of the suction bowl cannot accommodate treatment of multiple areas. For example, suction bowls with a flat rim are mainly suitable for treating flat areas. When used on round areas such as the arms and legs, the suction bowl is not firmly attached and easily loosens, directly affecting the treatment effect. If the suction bowl needs to be replaced, the entire treatment head must be replaced, which is inconvenient and costly.

[0007] In summary, how to effectively solve the problems of existing treatment heads having a single target area and limitations when used on different sites is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0031] The core of this invention is to provide a treatment head, the adsorption bowl of which includes various bowl shapes. Different bowl shapes can be selected according to different treatment sites to improve the treatment effect.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of a treatment head provided in a specific embodiment of the present invention; Figure 2 This is a cross-sectional view of the treatment head; Figure 3 This is a schematic diagram of the shell structure; Figure 4 A schematic diagram of the structure of the adsorption bowl used for the flat area; Figure 5 This is a schematic diagram of the structure using an adsorption bowl for the circular part.

[0034] In one specific embodiment, the treatment head provided by this utility model includes a housing 1 with an exhaust nozzle 14, a transducer 3 connected inside the housing 1, a first connecting part on the outer wall of the housing 1 and a first air outlet 15 on its side wall, the first air outlet 15 communicating with the exhaust nozzle 14; it also includes a plurality of adsorption bowls 2 detachably connected to the housing 1, the plurality of adsorption bowls 2 having different bowl shapes, the housing 1 selecting one of the adsorption bowls 2 to connect, the inner wall of the adsorption bowl 2 having a second connecting part and a second air outlet 21 on its side wall, when connected, the connecting end of the adsorption bowl 2 is sleeved on the outer periphery of the housing 1, the first connecting part and the second connecting part are sealed together, and the first air outlet 15 and the second air outlet 21 are connected.

[0035] In the above structure, a transducer 3 is connected inside the housing 1. The transducer 3 is used to convert electrical energy into ultrasonic energy or other energy forms required for treatment. An exhaust nozzle 14 is provided on the housing 1, and the exhaust nozzle 14 is connected to the treatment host via an air tube, allowing the treatment host to expel gas from the adsorption bowl 2. A first vent 15 is also provided on the side wall of the housing 1, and a second vent 21 is provided on the side wall of the adsorption bowl 2. The exhaust nozzle 14 communicates with the first vent 15 inside the housing 1, and the second vent 21 and the first vent 15 are interconnected. Gas enters the exhaust nozzle 14 from inside the adsorption bowl 2 through the second vent 21 and the first vent 15, and then exits through the air tube, thereby creating a negative pressure inside the adsorption bowl 2, realizing the adsorption treatment function of the adsorption bowl 2.

[0036] The suction bowl 2 is the part that contacts the treatment head and the treatment body, and it can be made of silicone. The treatment head is equipped with multiple suction bowls 2, which have different bowl shapes to adapt to the treatment needs of different parts of the body. These include at least: a bowl for flat areas, suitable for flat parts of the body such as the abdomen and back; and a bowl for round areas, suitable for round parts of the body such as the arms and legs. The bowl for round areas has an arc-shaped bowl tail 24, which allows for a tight contact with the round area to prevent air leakage.

[0037] The outer wall of the housing 1 is provided with a first connecting part, and the inner wall of each adsorption bowl 2 is provided with a second connecting part. The first connecting part of the housing 1 and the second connecting part of the adsorption bowl 2 are sealed together to ensure that no gas leakage occurs during treatment, thereby improving the safety and effectiveness of the treatment. The connection between the adsorption bowl 2 and the housing 1 is detachable, allowing users to quickly replace the appropriate adsorption bowl 2 according to different treatment sites.

[0038] When using it, select a suitable adsorption bowl 2, and put the connecting end of the adsorption bowl 2 on the outer periphery of the shell 1 to make the first connecting part and the second connecting part sealed and connected, while ensuring that the first air outlet 15 and the second air outlet 21 are connected.

[0039] The treatment head provided by this invention, equipped with various suction bowls 2 of different shapes, can flexibly adapt to various treatment sites. Users can easily replace the suction bowls 2 according to specific treatment needs, ensuring that the treatment head can achieve firm adhesion and optimal effect in different areas, thereby significantly improving the accuracy and effectiveness of treatment and greatly enhancing its applicability to different sites. Furthermore, the suction bowls 2 and the housing 1 are detachably connected, making connection and disassembly extremely simple, ensuring that the replacement of the suction bowls 2 is simple and quick, further improving the flexibility and convenience of treatment.

[0040] Based on the above specific embodiments, an additional bowl opening is also included, which is sealed to the outer wall of the adsorption bowl 2. The shape of the additional bowl opening is different from that of the bowl opening of the adsorption bowl 2.

[0041] In one specific embodiment, the shape of the additional bowl opening differs from that of the adsorption bowl 2. The additional bowl opening can be designed according to specific treatment needs. For example: a flat bowl opening is suitable for flat areas such as the abdomen and back; an oval bowl opening is suitable for oval-shaped areas of the body, such as the neck and wrists; and a curved bowl opening is suitable for curved areas of the body, such as the shoulders and knees.

[0042] The adsorption bowl 2 serves as the basic adsorption bowl. An additional bowl rim is sealed to the outer wall of the basic adsorption bowl 2, forming an additional adsorption bowl. The shape of the additional adsorption bowl rim differs from that of the basic adsorption bowl rim. This not only expands the applicability of the treatment head but also simplifies the number of adsorption bowls 2 required. For example, the basic adsorption bowl rim is designed for flat areas, suitable for flat parts of the body; while the additional bowl rim is designed for round areas. When combined with the basic adsorption bowl rim, the resulting additional adsorption bowl rim is also designed for round areas of the body.

[0043] In the above embodiments, users can adapt to various treatment sites not only by replacing the entire adsorption bowl 2, but also by attaching different additional bowl openings to the basic adsorption bowl. By replacing different additional bowl openings, users can easily adjust the shape and size of the adsorption bowl 2 to meet the treatment needs of different sites. This method reduces the number of complete adsorption bowls 2, making operation simpler and also reducing the cost of the treatment head.

[0044] Based on the above specific embodiments, the shell 1 and the adsorption bowl 2 are connected in the circumferential direction, as are the adsorption bowl 2 and the additional bowl opening in the circumferential direction, by a snap-fit ​​method of the protrusion 22 and the groove 16, and the top surface of the protrusion 22 and the bottom surface of the groove 16 are interference fit.

[0045] In one specific embodiment, the connection between the housing 1 and the adsorption bowl 2, as well as between the adsorption bowl 2 and the additional bowl opening, can be achieved by a snap-fit ​​method using protrusion 22 and groove 16. This snap-fit ​​method not only ensures the firmness and stability of the connection, but also further enhances the tightness and sealing of the connection through the interference fit between the top surface of the protrusion 22 and the bottom surface of the groove 16.

[0046] Specifically, the housing 1 and the adsorption bowl 2 are connected in the circumferential direction by a snap-fit ​​connection of a protrusion 22 and a groove 16. The outer wall of the housing 1 has a groove 16, which is the first connecting part, while the inner wall of the adsorption bowl 2 has a matching protrusion 22, which is the second connecting part. When the adsorption bowl 2 is installed on the housing 1, the protrusion 22 is inserted into the groove 16, achieving a tight connection between the two. This connection method is not only simple and quick, but also ensures the strength and sealing of the connection through interference fit, effectively preventing gas leakage.

[0047] Similarly, a similar connection method can be used between the adsorption bowl 2 and the auxiliary bowl opening. The outer wall of the adsorption bowl 2 has a protrusion 22, while the inner wall of the auxiliary bowl opening has a groove 16. The auxiliary bowl opening is tightly connected to the adsorption bowl 2 through the protrusion 22 and the groove 16. This design not only allows the auxiliary bowl opening to be firmly installed on the adsorption bowl 2, but also ensures the airtightness between the two through an interference fit, so that the auxiliary bowl opening and the adsorption bowl 2 can form a complete adsorption bowl unit, suitable for different treatment sites.

[0048] In the above embodiments, the snap-fit ​​design of the protrusion 22 and the groove 16, along with the interference fit, axially locks the groove 16 and the protrusion 22, ensuring a firm and reliable connection between the housing 1, the adsorption bowl 2, and the additional bowl opening. This prevents the two connected parts from easily separating, reducing the risk of loosening due to external forces or vibrations. The interference fit significantly improves the sealing performance at the connection, effectively preventing gas leakage and enhancing the safety and reliability of the equipment.

[0049] Based on the above specific embodiments, the housing 1 is provided with an installation groove at one end near the adsorption bowl 2, the transducer 3 is installed in the installation groove, the adsorption bowl 2 is provided with a support ring inside, the end of the support ring is shorter than the end of the adsorption bowl 2, and the support ring is interference-fitted with the outer wall of the installation groove.

[0050] Based on the above specific embodiments, the housing 1 has a mounting groove at one end near the adsorption bowl 2. The internal structure of the mounting groove matches the shape of the transducer 3, allowing the transducer 3 to be precisely installed within the mounting groove. The mounting groove supports and protects the transducer 3, ensuring its stability during operation. This design not only provides a stable mounting position for the transducer 3 but also provides space for electrical connections and heat dissipation.

[0051] The edge of the adsorption bowl 2 is the part that contacts the treatment body. The adsorption bowl 2 has a support ring inside. The end of the support ring is shorter than the end of the adsorption bowl 2. Sufficient space is left at the edge of the adsorption bowl 2 so that the support ring does not affect the normal contact between the edge of the adsorption bowl 2 and the treatment body, so that the adsorption bowl 2 can fit tightly against the surface of the treatment body.

[0052] The outer wall of the support ring and the outer wall of the mounting groove are interference-fitted, which not only ensures a tight connection between the support ring and the housing 1 and enhances the stability of the overall structure, but also ensures the sealing of the connection between the support ring and the housing 1.

[0053] Based on the above specific embodiments, the inner wall of the mounting groove is provided with a locking block 17, the outer wall of the transducer 3 is provided with a locking groove, the bottom surface of the mounting groove is provided with a boss, and there is a gap between the boss and the inner wall of the mounting groove. When connected, the bottom surface of the transducer 3 is in contact with the surface of the boss, the locking block 17 is inserted into the locking groove, and the gap is filled with sealant to seal the transducer 3 and the mounting groove.

[0054] Based on the above specific embodiments, the mounting groove is located at one end of the housing 1 near the adsorption bowl 2, which is the installation position for the transducer 3. The inner wall of the mounting groove is provided with a locking block 17, and the bottom surface of the mounting groove is provided with a boss. The outer wall of the transducer 3 is provided with a locking groove that matches the locking block 17 in the mounting groove. During installation, the bottom surface of the transducer 3 is tightly fitted with the surface of the boss on the bottom surface of the mounting groove, ensuring the stability and positioning accuracy of the transducer 3. Simultaneously, the locking block 17 engages with the locking groove, fixing the position of the transducer 3 and preventing it from shifting during operation. This installation method is not only simple and quick but also ensures the stability of the transducer 3 during use.

[0055] A gap is left between the boss and the inner wall of the mounting groove. To ensure the seal between the transducer 3 and the mounting groove, sealant is filled in the gap to complete the sealing treatment. The use of sealant prevents gas from leaking from the gap between the transducer 3 and the mounting groove, ensuring the sealing performance of the treatment head.

[0056] Furthermore, the bottom surface of the transducer 3 is chamfered to increase the contact area between the sealant and the transducer 3, thereby enhancing the sealing performance.

[0057] Based on the above specific embodiments, the inner wall of the support ring is provided with a limiting block 23, and there is a gap between the limiting block 23 and the surface of the transducer 3, and the pill is connected in the gap.

[0058] Based on the above specific embodiments, a support ring is located inside the adsorption bowl 2, providing connection support for the adsorption bowl 2 and ensuring that it maintains a fixed position during operation. A limiting block 23 is provided on the inner wall of the support ring, and a gap is provided between the limiting block 23 and the surface of the transducer 3. The size of this gap can be adjusted according to the thickness of the tablet. The tablet is installed between the limiting block 23 and the transducer 3 through this gap. During use, the limiting block 23 blocks the tablet to prevent it from falling off, thereby ensuring that the tablet can be tightly bound to the transducer 3 during treatment. This ensures that under the action of ultrasound, the drug can be evenly transmitted through the skin into the body, improving the effect of ultrasound-guided drug delivery therapy.

[0059] In the above embodiments, the limiting block 23 not only fixes the position of the tablet, but also provides a stable installation position for the tablet, so that the tablet can remain stable.

[0060] Based on the above specific embodiments, the position of the limiting block 23 can be moved along the axial direction of the support ring to adjust the size of the gap.

[0061] Based on the above specific embodiments, a certain gap is maintained between the limiting block 23 and the surface of the transducer 3. The position of the limiting block 23 can move along the axial direction of the support ring, thereby flexibly adjusting the size of the gap. Precisely positioning the limiting block 23 according to the thickness of the tablet or treatment needs can ensure that the tablet is tightly bonded to the transducer 3 during treatment, avoiding poor contact or damage caused by the tablet being too thick or too thin.

[0062] In the above embodiments, the adjustability between the support ring and the limiting block 23 not only provides a stable installation position for the tablet, but also improves the effect of ultrasound transdermal drug delivery by flexibly adjusting the gap, thereby enhancing the overall performance and versatility of the device.

[0063] Based on the above specific embodiments, the support ring is provided with an elongated hole along the axial direction, and the limiting block 23 is provided with a screw. The screw is connected to the elongated hole and its end is fastened by a nut. The screw can move along the elongated hole.

[0064] Based on the above specific embodiments, the support ring is provided with an elongated hole along the axial direction, which provides a basis for the adjustability of the limiting block 23.

[0065] The limiting block 23 is equipped with a screw, which is connected to an elongated hole in the support ring and secured at its end with a nut. The screw can move axially within the elongated hole, thereby causing the limiting block 23 to move axially along the support ring. By tightening or loosening the nut, the position of the limiting block 23 can be precisely adjusted, thereby changing the size of the gap between the limiting block 23 and the surface of the transducer 3.

[0066] In practice, users can loosen the nut and move the screw along the elongated hole to adjust the position of the limiting block 23 according to the thickness of the tablet or treatment needs, to achieve a suitable gap size. After adjustment, tighten the nut to fix the limiting block 23 in the appropriate position. This adjustable method not only improves the flexibility and applicability of the equipment, but also ensures that the tablet can be tightly combined with the transducer 3 during treatment, improving the treatment effect.

[0067] Based on the above specific embodiments, there is a channel between the adsorption bowl 2 and the support ring, and the second air outlet 21 is provided on the support ring.

[0068] Based on the above specific embodiments, a channel is formed between the adsorption bowl 2 and the support ring to guide gas flow. A second vent 21 is located on the support ring and communicates with the first vent 15. Gas flows from inside the adsorption bowl 2 through the channel to the second vent 21, then through the first vent 15 into the exhaust nozzle 14, and finally exits. After the gas in the adsorption bowl 2 is discharged through the exhaust nozzle 14, a negative pressure is formed inside the adsorption bowl 2. This negative pressure environment allows the adsorption bowl 2 to firmly adhere to the human body surface, ensuring close contact between the adsorption bowl 2 and the skin during treatment and improving the treatment effect.

[0069] The second vent 21 on the support ring is directly connected to the first vent 15 of the shell 1, ensuring smooth gas flow and a clear flow path, thus reducing the risk of leakage. The gas can be evenly distributed on the inner surface of the adsorption bowl 2, improving the treatment effect.

[0070] Based on the above specific embodiments, the outer wall of the mounting groove is provided with an insertion port, and the inner wall of the support ring is provided with an insertion block. The insertion block is inserted into the insertion port to position the first air outlet 15 and the second air outlet 21 to communicate.

[0071] Based on the above specific embodiments, the mounting groove is located at one end of the housing 1 near the adsorption bowl 2, and its outer wall is provided with an insertion port. The support ring is located inside the adsorption bowl 2, and its inner wall is provided with an insertion block. The insertion block matches the insertion port on the outer wall of the mounting groove and can be inserted into the insertion port, realizing precise positioning between the mounting groove and the support ring, making the installation and replacement of the adsorption bowl 2 and the housing 1 more convenient.

[0072] The engagement of the insert block and the socket provides mechanical positioning, preventing relative rotation between the adsorption bowl 2 and the housing 1, and making the connection between the support ring and the mounting groove more stable, reducing the risk of gas leakage due to vibration or external force.

[0073] When the insert block is inserted into the socket, the first vent 15 and the second vent 21 can be precisely connected, thereby ensuring that the gas can flow smoothly from the adsorption bowl 2 to the shell 1 and finally be discharged from the adsorption bowl 2. The cooperation between the insert block and the socket ensures the precise connection between the first vent 15 and the second vent 21, improving the accuracy of the gas flow path.

[0074] Based on the above specific embodiments, the housing 1 includes a main body 12 and a top cover 11 detachably connected to the main body 12. The mounting groove and the exhaust nozzle 14 are provided inside the main body 12. The fastening surfaces of the main body 12 and the top cover 11 are provided with wire holes 13. An integrated wire 4 passes through the wire holes 13 and its cable is connected to the transducer 3. The air pipe is connected to the exhaust nozzle 14.

[0075] Based on the above specific embodiments, the housing 1 consists of two parts: a main body 12 and a top cover 11, which are tightly connected by a snap-fit ​​surface. The mounting groove and the exhaust nozzle 14 are both located inside the main body 12. The mounting groove is used to fix the transducer 3, ensuring its stability during operation; the exhaust nozzle 14 is connected to the treatment unit via an air pipe, used to expel gas from the adsorption bowl 2, creating negative pressure to achieve the adsorption function. The top cover 11 and the main body 12 are detachably connected, allowing users to easily open the top cover 11 to inspect or replace internal components, improving the ease of maintenance.

[0076] The mating surfaces of the main body 12 and the top cover 11 are provided with wire passage holes 13, which provide a channel for the orderly arrangement of wires and air tubes. The integrated wire 4 is composed of a five-core wire and an air tube, allowing the wires and air tubes to pass through the same wire passage hole 13, greatly simplifying the wiring. The five-core wire is connected to the transducer 3, providing power to the transducer 3 and ensuring its normal operation. At the same time, the air tube is connected to the exhaust nozzle 14, forming a complete gas flow path, ensuring that the gas can be smoothly discharged from the inside of the adsorption bowl 2 and released through the exhaust nozzle 14, thereby creating a negative pressure environment inside the adsorption bowl 2 and achieving a stable adsorption function.

[0077] In use, the transducer 3 is installed in the mounting groove of the housing 1 and sealed with sealant. The integrated wire 4 passes through the wire hole 13 and the five-core wire of the integrated wire 4 is soldered to the transducer 3. The air pipe is connected to the exhaust nozzle 14. Then, the flat part or the round part is installed on the main body 12 with an adsorption bowl. The first protrusion 22 and the first groove 16 are first aligned. The second air outlet 21 of the adsorption bowl 2 is aligned with the first air outlet 15 of the housing 1. The other end of the integrated wire 4 is connected to the treatment host to realize the corresponding function.

[0078] This design not only ensures the functional integrity of the equipment, but also makes the arrangement of wires and air pipes neater and more orderly through integrated design, reducing the impact of messy cables on operation, improving the safety of the equipment, and reducing the potential risks caused by tangled or loose cables.
