Description

Technical Field

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

[0002] An ultrasound therapy device is a medical device that uses ultrasound waves for treatment. Ultrasound therapy devices typically convert electrical energy into ultrasound waves through a transducer. These ultrasound waves can stimulate human tissue to achieve therapeutic purposes.

[0003] Because the transducer of the ultrasound treatment head needs to operate within a sealed water tank, it generates heat during operation, creating significant pressure within the tank. If this pressure isn't released, the tank's seal will eventually fail, damaging the treatment head. Furthermore, the ultrasound output window may bulge outwards due to expansion pressure, affecting its contact with the skin. Utility Model Content

[0004] The main purpose of this invention is to propose a treatment head and an ultrasonic therapy device, which aims to balance the internal and external atmospheric pressure of the treatment head and improve the sealing performance of the treatment head.

[0005] To achieve the above objectives, the present invention proposes a treatment head comprising a housing, a partition, and a pressure regulating component. The housing contains an installation space. The partition is disposed within the installation space, dividing it into a first receiving cavity and a second receiving cavity. A transducer assembly is disposed within the first receiving cavity, and a circuit assembly is disposed within the second receiving cavity. The circuit assembly is electrically connected to the transducer assembly. The partition has a pressure relief hole connecting the first and second receiving cavities. The pressure regulating component is disposed within the first receiving cavity and forms a pressure relief cavity with an opening. The opening communicates with the pressure relief hole, and the pressure relief cavity communicates with the second receiving cavity through the opening and the pressure relief hole. The second receiving cavity has an exhaust hole communicating with the outside. The exhaust hole is covered with a sealing mesh, which is used to discharge gas from the second receiving cavity to the outside through the exhaust hole or to absorb gas from the outside.

[0006] In one embodiment, the circuit assembly includes a main control board and a connecting board that are electrically connected. The main control board is connected to the partition and electrically connected to the transducer assembly. The main control board has a first through hole communicating with the pressure relief hole. The connecting board is connected to a cavity wall of the second receiving cavity away from the partition. The connecting board has a second through hole communicating with the exhaust hole.

[0007] In one embodiment, the sealing mesh is sandwiched between the edge of the second through hole and the edge of the vent hole.

[0008] In one embodiment, the connecting plate is provided with a plurality of copper pillars, the housing is provided with a plurality of connecting holes, one of the copper pillars passes through one of the connecting holes, and a sealing sleeve is sandwiched between the connecting plate and the housing, the sealing sleeve being used to seal the gap between the connecting hole and the copper pillar.

[0009] In one embodiment, a power groove is formed in the middle of the partition extending toward the second receiving cavity, a power connector is provided in the power groove, a power interface is provided in a cavity wall of the second receiving cavity away from the partition, and a sealing groove is provided on the edge of the power interface;

[0010] The treatment head also includes a seal, which is disposed in the sealing groove. The power connector passes through the power interface, and the groove wall of the power groove abuts the seal against the bottom of the sealing groove.

[0011] In one embodiment, the pressure regulating member includes an integrally formed connecting portion and a pressing portion. The connecting portion passes through the pressure relief hole, and the other end of the connecting portion away from the pressing portion has the opening, which communicates with the pressure relief hole.

[0027] An ultrasound therapy device is a medical device that uses ultrasound waves for treatment. Ultrasound therapy devices typically convert electrical energy into ultrasound waves through a transducer. These ultrasound waves can stimulate human tissue to achieve therapeutic purposes.

[0028] Because the transducer of the ultrasonic treatment head needs to work in a sealed water tank, the transducer generates heat during operation, and the water tank generates huge pressure. If the pressure in the water tank is not released, the seal of the water tank will fail over time, which will damage the treatment head.

[0029] This invention proposes a treatment head and an ultrasonic therapy device, which aims to balance the atmospheric pressure inside and outside the water tank of the treatment head, prevent water tank seal failure, and improve the sealing performance of the treatment head.

[0030] Please see Figure 1 and Figure 3In one embodiment of this utility model, the treatment head 100 includes a housing 1, a partition 2, and a pressure regulating member 3. An installation space is formed within the housing 1. The partition 2 is disposed within the installation space, dividing the installation space into a first receiving cavity 11 and a second receiving cavity 12. A transducer assembly is disposed within the first receiving cavity 11, and a circuit assembly is disposed within the second receiving cavity 12. The circuit assembly is electrically connected to the transducer assembly. The partition 2 has a pressure relief hole 21 connecting the first receiving cavity 11 and the second receiving cavity 12. The pressure regulating member 3 is disposed within the first receiving cavity 11 and forms a pressure relief cavity with an opening. The opening communicates with the pressure relief hole 21, and the pressure relief cavity communicates with the second receiving cavity 12 through the opening and the pressure relief hole 21. The second receiving cavity 12 has an exhaust hole 141 communicating with the outside. The exhaust hole 141 is covered with a sealing mesh 142, which is used to discharge gas from the second receiving cavity 12 to the outside or absorb gas from the outside.

[0031] In this embodiment, the shape and material of the housing 1 and the partition 2 are common shapes and materials on the market. The partition 2 is disposed inside the housing 1, dividing the housing 1 into a first receiving cavity 11 and a second receiving cavity 12 that are not interconnected. A transducer assembly is disposed in the first receiving cavity 11, and a circuit assembly is disposed in the second receiving cavity 12. The circuit assembly is electrically connected to the transducer assembly. The transducer assembly and the circuit assembly also use transducers and circuit boards commonly used in ultrasonic treatment heads 100. A pressure relief hole 21 is provided on the partition 2 to connect the first receiving cavity 11 and the second receiving cavity 12. The pressure regulating component 3 has a pressure relief chamber with an opening. The opening of the pressure relief chamber is connected to the pressure relief hole 21. The pressure regulating component 3 is made of a deformable material, such as silicone, rubber, or plastic. The connection method between the pressure regulating component 3 and the partition 2 can be to bond the opening to the edge of the pressure relief hole 21 on the partition 2, or it can be a plug-in connection method, etc., which is not further limited here. When the treatment head 100 is in operation, the transducer assembly generates heat, increasing the pressure in the first receiving cavity 11. This pressure increases the pressure regulating component 3, forcing the gas in its depressurization chamber into the second receiving cavity 12. This balances the pressure in the first and second receiving cavities, preventing seal failure in the first receiving cavity 11 and extending the service life of the treatment head 100. The second receiving cavity 12 has an exhaust port 141 communicating with the outside. A sealing mesh 142 covers the exhaust port 141, allowing gas to escape unidirectionally from the second receiving cavity 12 to the outside. However, external water cannot enter the second receiving cavity 12 through the sealing mesh 142, improving the sealing performance of the treatment head 100. The sealing mesh 142 can be made of one of the following materials: polytetrafluoroethylene, polyurethane, thermoplastic polyurethane, polypropylene, polyethylene, or a silicone breathable membrane.

[0032] The technical solution of this utility model uses a pressure regulating component 3 to balance the pressure in the first receiving cavity 11 and the second receiving cavity 12. The transducer assembly is disposed in the first receiving cavity 11, and the circuit assembly is disposed in the second receiving cavity 12. When the treatment head 100 is working, the transducer assembly generates heat, increasing the pressure in the first receiving cavity 11. This pressure increases the pressure of the pressure regulating component 3, forcing the gas in its pressure relief chamber into the second receiving cavity 12, thus balancing the pressure in both cavities. The second receiving cavity 12 has an exhaust port 141 communicating with the outside. A sealing mesh 142 is provided on the edge surface of the exhaust port 141 facing the second receiving cavity 12, allowing gas to be discharged to the outside to balance the pressure inside the treatment head 100 and prevent seal failure. Furthermore, the sealing mesh 142 only allows gas to be discharged and inhaled, preventing moisture and dust from entering the housing 1, thus improving the sealing performance of the treatment head 100. In a preferred embodiment, there are two vent holes 141, and each vent hole 141 is covered with a sealing mesh 142 to further balance the atmospheric pressure inside and outside the water tank of the treatment head 100, prevent the water tank seal from failing, and improve the sealing performance of the treatment head 100.

[0033] In an embodiment of this utility model, the circuit assembly includes a main control board 15 and a connecting plate 16 that are electrically connected. The main control board 15 is connected to the partition 2 and is electrically connected to the transducer assembly. The main control board 15 has a first through hole 151 that communicates with the pressure relief hole 21. The connecting plate 16 is connected to a cavity wall of the second receiving cavity 12 away from the partition 2. The connecting plate 16 has a second through hole 161 that communicates with the exhaust hole 141.

[0034] In this embodiment, the circuit assembly includes a main control board 15 and a connecting board 16 electrically connected. The connecting board 16 and the main control board 15 are electrically connected to the transducer assembly to supply power to the transducer assembly. The main control board 15 has a first through hole 151 communicating with the pressure relief hole 21, and the connecting board 16 has a second through hole 161 communicating with the exhaust hole 141 and the second receiving cavity 12. When the pressure in the first receiving cavity 11 rises, it squeezes the pressure regulating member 3. The gas in the pressure relief chamber of the pressure regulating member 3 is discharged into the second receiving cavity 12 and discharged into the external space through the second through hole 161 and the exhaust hole 141 on the connecting board 16, so that the pressure in the second receiving cavity 12 is balanced with the external environment, thereby balancing the pressure in the first receiving cavity 11 with the external atmospheric pressure, reducing the impact of the pressure in the first receiving cavity 11 on the seal, and improving the service life of the treatment head 100.

[0037] In an embodiment of this utility model, a plurality of copper pillars 162 are provided on the connecting plate 16, a plurality of connecting holes are provided on the housing 1, a copper pillar 162 passes through a connecting hole, and a sealing sleeve 163 is sandwiched between the connecting plate 16 and the housing 1.

[0038] In this embodiment, the connecting plate 16 is provided with a plurality of copper pillars 162, which pass through the connecting holes of the housing 1 and are electrically connected to the treatment handle of the therapeutic instrument through the copper pillars 162, thereby realizing the electrical connection between the treatment handle and the connecting plate 16, and further realizing the electrical connection with the main control board 15 and the transducer assembly. A sealing sleeve 163 is also provided between the connecting plate 16 and the housing 1. The sealing sleeve 163 can be made of silicone or rubber. The connecting plate 16 clamps the sealing sleeve 163 between the housing 1, which can seal the gap between the copper pillars 162 and the connecting holes, thereby improving the overall sealing performance of the treatment head 100.

[0039] In an embodiment of this utility model, a power groove is formed in the middle of the partition 2 extending toward the second receiving cavity 12. A power connector is provided in the power groove. A power interface is provided on the cavity wall of the second receiving cavity 12 away from the partition 2. A sealing groove is provided on the edge of the power interface.

[0040] The treatment head 100 also includes a seal 17, which is disposed in a sealing groove. The power connector passes through the power interface, and the groove wall of the power groove abuts the seal 17 against the bottom of the sealing groove.

[0041] In this embodiment, the treatment head 100 is further provided with a power connector, which is disposed in a power groove extending from the partition 2. A power interface is provided on the housing 1, and a sealing groove is provided along the edge of the power interface. A sealing element 17 is provided within the sealing groove, which can be a sealing strip or a sealing ring, etc. The power connector passes through the power interface and connects to the output shaft of the treatment handle, causing the wall of the power groove to abut against the sealing element 17 and the bottom of the sealing groove, thereby reducing the gap between the power connector, the power interface, and the second receiving cavity 12, thus improving the overall sealing performance of the treatment head 100.

[0042] In an embodiment of this utility model, the pressure regulating member 3 includes an integrally formed connecting part 31 and a pressing part 32. The connecting part 31 passes through the pressure relief hole 21, and the other end of the connecting part 31 away from the pressing part 32 has an opening that communicates with the pressure relief hole 21.

[0043] In this embodiment, the pressure regulating component 3 includes a connecting portion 31 and a pressing portion 32, which are integrally formed. The connecting portion 31 passes through the pressure relief hole 21, so that the opening of the connecting portion 31 communicates with the pressure relief hole 21, thereby communicating the pressure relief chamber with the second receiving chamber 12. The connecting portion 31 passing through and connecting to the pressure relief hole 21 can improve the connection strength between the connecting portion 31 and the pressure relief hole 21, prevent the pressure balance function from failing, and extend the service life of the treatment head 100.

[0044] In an embodiment of this utility model, the end of the extrusion portion 32 away from the connecting portion 31 is formed into a cone shape.

[0045] In this embodiment, the end of the extrusion part 32 away from the connecting part 31 is formed into a cone shape. When the end of the cone shape is subjected to pressure, it is easier to be extruded and deformed, thereby causing the extrusion part 32 of the pressure regulating member 3 to deform as a whole, so as to discharge the gas in the pressure relief chamber to the second receiving chamber 12, so as to balance the pressure of the first receiving chamber 11 and the second receiving chamber 12, prevent the seal in the first receiving chamber 11 from failing, and improve the service life of the treatment head 100.

Correspondingly, the number of pressure relief holes 21 opened on the partition 2 is the same as the number of pressure regulating components 3, and the opening of one pressure regulating component 3 is connected to one pressure relief hole 21. When the pressure in the first receiving cavity 11 rises, at least two pressure regulating components 3 are squeezed simultaneously to discharge the gas in the pressure relief cavity into the second receiving cavity 12.

[0048] In one example, at least two pressure relief holes 21 are evenly distributed along the cross-sectional direction of the partition 2, and correspondingly, at least two pressure regulating elements 3 are evenly distributed along the cross-sectional direction of the first receiving cavity 11, which enables the pressure in the first receiving cavity 11 to be evenly balanced with the second receiving cavity 12, and the pressure at all points in the first receiving cavity 11 to be balanced with the second receiving cavity 12, thereby further improving the service life of the treatment head 100.
