Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an ultrasonic treatment head airtightness detection device. Background Technology

[0002] Ultrasound is a high-frequency mechanical wave with focusable properties, tissue penetration, and energy deposition. An ultrasound therapy device is an instrument that uses a focused ultrasound transducer to focus ultrasound waves onto a living organism. The interaction between the ultrasound waves and biological tissue produces thermal, cavitation, and mechanical effects, thus exerting corresponding biological effects. It includes an ultrasound therapy handpiece and a treatment head, which are detachably connected. The transducer in the treatment head emits ultrasound waves to act on the skin.

[0003] Utility model patent application number CN202420247388.4 discloses a handheld component for an ultrasonic therapy device, including a handle and a treatment head. The handle includes a drive module and a telescopic coupling assembly, with the drive module fixedly connected to one end of the telescopic coupling assembly. The treatment head is detachably connected to the handle and includes a transducer assembly and a transmission assembly, with the transmission assembly coupled to the other end of the telescopic coupling assembly. The drive module is used to drive the transducer assembly to perform reciprocating motion in a linear direction through the telescopic coupling assembly and the transmission assembly.

[0004] The treatment head's housing is filled with a liquid that can conduct ultrasound waves, and the treatment window of the housing is sealed by an acoustic membrane. The acoustic membrane is connected to the treatment window of the housing by adhesive. During use, if the treatment head housing leaks liquid, it can easily flow into the handle, causing a short circuit in the circuit board. Therefore, to avoid leakage, existing treatment heads, after assembly, rely solely on visual inspection of the outer side of the treatment head housing to check for liquid leakage by shaking the treatment head and / or pulling the transmission component. This method is inefficient, unreliable, and not conducive to testing the airtightness of the housing. Utility Model Content

[0011] The locking assembly is used to connect the limiting clamp and the sealing plate to prevent the sealing plate from falling off.

[0012] As a further improvement to the above technical solution: the locking assembly includes a fixing plate, a locking hook, a wrench, and a locking buckle; the fixing plate is located on one side of the limiting clamp, the locking hook is located on one side of the sealing plate and corresponds to the fixing plate; the end of the wrench is hinged to the fixing plate, one end of the locking buckle is hinged to the middle of the wrench, and the other end can cooperate with the locking hook.

[0014] As a further improvement to the above technical solution: the locking assembly is provided in two sets, and is respectively located on both sides of the limiting clamp.

[0015] As a further improvement to the above technical solution: the inflation assembly includes an air source, an air pipe and a connector, the air pipe is connected between the air source and the connector, and the connector is connected to the air hole.

[0016] As a further improvement to the above technical solution: a pressure gauge is provided on the trachea.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. The ultrasonic treatment head airtightness testing device disclosed in this utility model allows for the following steps: During use, the treatment head housing is installed in a receiving groove, and the receiving groove on the limiting clamp stably fixes the treatment head; a sealing plate seals the treatment window of the treatment head; a locking assembly connects the limiting clamp and the sealing plate, ensuring a tight fit between the sealing plate and the treatment window and preventing the sealing plate from falling off; air is inflated into the treatment head via an inflation assembly, and after inflation, the airtightness of the treatment head housing can be determined by observing whether there is an airflow sound or by placing the treatment head in water to observe whether bubbles emerge. This airtightness testing device effectively detects the airtightness of the ultrasonic treatment head, improving the yield rate of the treatment head housing and enhancing its safety and reliability. After the treatment head housing passes the airtightness testing device, subsequent operations such as liquid filling and installation of a sound-permeable membrane can be performed.

[0023] 2. The ultrasonic treatment head airtightness testing device disclosed in this utility model further includes a pressure gauge that can monitor the pressure change after inflation in real time.

[0029] like Figure 1 and Figure 2 As shown, the ultrasonic treatment head airtightness detection device of this embodiment includes a limiting clamp 10, a sealing plate 20, an inflation assembly 30, and a locking assembly 40.

[0030] The limiting clamp 10 is provided with a receiving groove for accommodating the treatment head 50;

[0031] The sealing plate 20 is used to seal the treatment window of the treatment head 50 and is provided with an air hole 21;

[0032] The inflation assembly 30 is connected to the air vent 21 and is used to inflate the treatment head 50;

[0033] The locking assembly 40 is used to connect the limiting clamp 10 and the sealing plate 20 to prevent the sealing plate 20 from falling off.

[0034] In use, the ultrasonic treatment head airtightness testing device is used such that the treatment head 50 housing is installed in the receiving groove, and the treatment head 50 is stably fixed by the receiving groove on the limiting clamp 10; the treatment window of the treatment head 50 is sealed by the sealing plate 20; the limiting clamp 10 and the sealing plate 20 are connected by the locking component 40, so that the sealing plate 20 is tightly abutted against the treatment window and can prevent the sealing plate 20 from falling off; air is inflated into the treatment head 50 by the inflation component 30. After inflation, it can be observed whether there is an airflow sound in the treatment head 50 housing, or the treatment head 50 can be placed in water to observe whether bubbles emerge, thereby judging the airtightness of the treatment head 50 housing. This airtightness testing device can effectively detect the airtightness of the ultrasonic treatment head 50, improve the yield rate of the treatment head 50 housing, and improve the safety and reliability of use. After the treatment head 50 housing passes the airtightness testing device, subsequent operations such as liquid filling and installation of sound-permeable membrane can be performed.

[0035] In this embodiment, two sets of locking components 40 are provided, respectively located on both sides of the limiting clamp 10. Specifically, the two sets of locking components 40 can further ensure the locking effect and further prevent the sealing plate 20 from falling off.

[0036] In this embodiment, the locking assembly 40 includes a fixing plate 41, a locking hook 42, a wrench 43, and a locking buckle 44; the fixing plate 41 is located on one side of the limiting clamp 10, and the locking hook 42 is located on one side of the sealing plate 20 and corresponds to the fixing plate 41; the end of the wrench 43 is hinged to the fixing plate 41, one end of the locking buckle 44 is hinged to the middle of the wrench 43, and the other end can cooperate with the locking hook 42. Specifically, as shown... Figure 1 and Figure 2 As shown, when the sealing plate 20 comes into contact with the treatment window, the wrench 43 is turned upwards to engage the locking buckle 44 with the locking hook 42, thereby tightening the sealing plate 20 to enhance the sealing effect and prevent it from falling off. The operation of the wrench 43 can achieve quick locking and unlocking, which improves the stability and ease of operation of the detection device.

[0037] In this embodiment, the wrench 43 has a pivot 431 in the middle, and the latch 44 is connected to the pivot 431. Specifically, the pivot 431 enables the hinge to be made, making the movement of the latch 44 more flexible and allowing it to cooperate more stably with the hook 42.

[0038] In this embodiment, the fixing plate 41 is bolted to the limiting clamp 10, and the locking hook 42 is bolted to the sealing plate 20. Specifically, the two sides of the sealing plate 20 extend downward to form fixed edges, and the locking hook 42 is bolted to the fixed edges of the sealing plate 20; the fixing plate 41 and the locking hook 42 are bolted together, which improves the overall stability of the detection device and facilitates disassembly and maintenance.

[0039] In this embodiment, the inflation assembly 30 includes an air source 31, an air pipe 32, and a connector 33. The air pipe 32 connects the air source 31 and the connector 33, and the connector 33 is connected to the air port 21. Specifically, this structure enables the inflation assembly 30 to stably inflate the treatment head 50, providing reliable air supply support for airtightness testing. It also facilitates installation and maintenance, improving the practicality and reliability of the testing device. The air source 31 can be an existing structure such as an air pump or air compressor, making operation convenient.

[0040] In this embodiment, a pressure gauge 34 is provided on the trachea 32. Specifically, the pressure gauge 34 can monitor the pressure change after inflation in real time. A decrease in the pressure gauge 34 indicates that the shell is leaking air, avoiding operations such as immersing the shell in water. This further facilitates the airtightness detection of the treatment head 50 shell, makes it easier to observe, and improves the accuracy of the detection.

[0041] In this embodiment, a sealing layer 22 is provided on the sealing plate 20, and the sealing layer 22 corresponds to the treatment window. Specifically, the sealing layer 22 is a rubber layer, which can fit tightly with the treatment window, effectively preventing air leakage and improving the accuracy of detection; it also has a certain degree of corrosion resistance and wear resistance, extending the service life of the sealing layer 22.

[0042] In this embodiment, the limiting clamp 10 is a U-shaped clamp. Specifically, the U-shaped clamp has a simple structure, is easy to install and disassemble, and can quickly fix and release the treatment head 50, improving the operational convenience and work efficiency of the detection device.

[0043] The method of using the ultrasound treatment head airtightness detection device is as follows:
