Technical Field
[0001] This utility model relates to the field of ultrasonic diaphragm sound-permeable membrane technology, specifically an ultrasonic isolation sound-permeable membrane. Background Technology
[0002] Ultrasonic technology, developed in the 20th century, is a new, interdisciplinary science that has attracted widespread attention from scientists and engineers in countries such as the United States, Germany, Canada, Japan, and China. The development of ultrasonic technology has opened up new fields of research in chemical engineering, food science, biology, and medicine, and has had a significant impact on these industries in terms of application. As an important part of acoustic research, ultrasonic technology has also made progress in modern separation techniques. It is believed that ultrasound has three basic mechanisms of action: mechanical, thermal, and cavitation mechanisms. Due to the unique nature of ultrasound, its importance in various separation fields is increasingly evident. Ultrasonic waves acting on two-phase or multiphase systems produce various effects, such as cavitation, turbulence, perturbation, interface, and focusing effects. Among these, turbulence thins the boundary layer, increasing the mass transfer rate; perturbation enhances microporous diffusion; interface increases the mass transfer surface area; and focusing activates the molecules of the separated substances. All these effects cause unique changes in the propagation medium, thus promoting the separation process as a whole.
[0003] With the application of ultrasound technology in the medical field, the level of medical testing has been greatly improved. When using ultrasound equipment, it is often necessary to use an ultrasound probe to detect the lesions of patients. In order to prevent cross-infection, a membrane needs to be put on the ultrasound probe.
[0004] Existing ultrasonic isolation sound-permeable membranes are inconvenient to install and replace quickly.
[0005] Secondly, due to the different probe specifications, it is difficult to ensure that the sound-transmitting membrane and the probe are fully fitted, which may cause displacement problems during use, affecting the detection speed and accuracy of the probe, and urgently needs to be developed. Utility Model Content
[0006] The purpose of this invention is to provide an ultrasonic isolation sound-permeable membrane to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic isolation sound-permeable membrane, comprising an ultrasonic head, an installation connecting edge, a sound-permeable membrane body, and a pressing block. The lower surface of the ultrasonic head is connected to the installation connecting edge, and the upper surface of the installation connecting edge is provided with a supporting edge at the connection point between it and the bottom of the ultrasonic head. An inner hook positioning edge is connected to the side of the supporting edge away from the ultrasonic head. An avoidance groove is connected to the top of the installation connecting edge at the connection point between it and the bottom of the supporting edge. A pressing block is connected to the avoidance groove via a hinge seat. The expansion of the tension spring causes the pressing block to press against the edge of the sound-permeable membrane body fitted at the inner hook positioning edge, reducing the problem of the sound-permeable membrane body falling off.
[0008] Preferably, a sound-permeable membrane is sandwiched between the inner hook positioning edge and the pressing block, and the sound-permeable membrane is fitted over the outside of the ultrasonic head.
[0009] Preferably, a connecting seat is provided between the inner surface of the acoustic membrane and the upper end of the ultrasonic sleeve, and the connecting seat is fixedly connected to the inner surface of the acoustic membrane.
[0010] Preferably, the inside of the connecting seat is connected to a limit sliding block via a return spring, and the expansion of the return spring enhances the adhesion and suction force between the connecting suction cup and the ultrasonic sleeve.
[0011] Preferably, the lower surface of the limiting sliding block is connected to a telescopic block, which extends to the bottom of the connecting seat and is connected to a connecting suction cup.
[0012] Preferably, both sides inside the connecting seat are connected to a guide groove that matches the limiting sliding block.
[0013] Preferably, a guide groove 2 is connected to one side of the clamping block, and a guide slider is slidably installed in the guide groove 2. The guide slider can slide along the guide groove 2 to adapt to the rotation of the clamping block.
[0014] Preferably, a tension spring is hinged to the guide slider, and the other end of the tension spring is hinged to the inner surface of the clearance groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] (1) This ultrasonic isolation sound-transparent membrane, when the sound-transparent membrane body is put on the outside of the ultrasonic head, the setting of the inner hook positioning edge and the support edge can play a limiting and locking role on the edge of the sound-transparent membrane body, which plays a good positioning role and reduces the problem of slippage during the fitting process of the sound-transparent membrane body. Secondly, the expansion of the tension spring, together with the guide slider sliding along the guide groove, makes the pressing block keep pressing the edge of the sound-transparent membrane body, fixing the edge of the sound-transparent membrane body between the inner hook positioning edge and the pressing block, improving the stability of fitting on the outside of the ultrasonic head, and this fitting method facilitates the subsequent quick disassembly action;
[0017] (2) With the setting of the connecting suction cup, when the sound-transparent membrane is fitted over the ultrasonic head, the connecting suction cup can be well adsorbed with the surface of the ultrasonic head, which plays a pre-positioning role and reduces the problem of the sound-transparent membrane slipping during the fitting and use process, which may affect subsequent use.
[0018] (3) This type of ultrasonic isolation sound-transmitting membrane, through the expansion of the reset spring and the action of the limiting sliding block sliding along the guide groove, allows the connecting suction cup to remain in close contact with the surface of the ultrasonic head for a long time, thereby improving the stability of the sound-transmitting membrane adsorbed outside the ultrasonic head. The sliding of the limiting sliding block along the guide groove allows the connecting suction cup to have an autonomous expansion and contraction function, which gives the sound-transmitting membrane a certain buffering effect and adaptability to movement when in contact with the patient's epidermis during use, resulting in better performance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0025] Please see Figure 1-4An embodiment of this utility model provides an ultrasonic isolation sound-permeable membrane, including an ultrasonic sleeve 1, an installation connecting edge 2, a sound-permeable membrane body 3, and a pressing block 17. The lower surface of the ultrasonic sleeve 1 is connected to the installation connecting edge 2, and the upper surface of the installation connecting edge 2 is provided with a support edge 16 at the connection between it and the bottom of the ultrasonic sleeve 1. The side of the support edge 16 away from the ultrasonic sleeve 1 is connected to an inner hook positioning edge 15. When the sound-permeable membrane body 3 is sleeved on the outside of the ultrasonic sleeve 1, the setting of the inner hook positioning edge 15 and the support edge 16 can limit and lock the edge of the sound-permeable membrane body 3, which can play a good positioning role and reduce the problem of slippage during the sleeve process of the sound-permeable membrane body 3.
[0026] An avoidance groove 14 is connected to the bottom of the support edge 16 at the top of the mounting connection edge 2, and a clamping block 17 is connected to the avoidance groove 14 through a hinge seat 13.
[0027] A sound-permeable membrane 3 is sandwiched between the inner hook positioning edge 15 and the pressing block 17, and the sound-permeable membrane 3 is fitted over the outside of the ultrasonic head 1.
[0028] A connecting seat 4 is provided between the inner surface of the acoustic membrane 3 and the upper end of the ultrasonic head 1, and the connecting seat 4 is fixedly connected to the inner surface of the acoustic membrane 3.
[0029] The interior of the connecting seat 4 is connected to the limiting sliding block 8 via a return spring 6. The expansion of the return spring 6, combined with the guiding sliding block 8 along the guide groove 7, ensures that the connecting suction cup 5 remains tightly attached to the surface of the ultrasonic sleeve 1 for a long time, thereby improving the stability of the sound-permeable membrane 3 adsorbed on the outside of the ultrasonic sleeve 1.
[0030] The lower surface of the limiting sliding block 8 is connected to a telescopic block 9. The telescopic block 9 extends to the bottom of the connecting seat 4 and is connected to a connecting suction cup 5. The connection suction cup 5 is designed so that when the sound-permeable membrane 3 is fitted over the ultrasonic head 1, the connecting suction cup 5 can be well adsorbed onto the surface of the ultrasonic head 1, which plays a pre-positioning role and reduces the problem of the sound-permeable membrane 3 slipping during the fitting and use process, which may affect subsequent use.
[0031] Both sides of the inside of the connecting seat 4 are connected to guide grooves 7 that match the limiting sliding block 8. The limiting sliding block 8 slides along the guide grooves 7, which enables the connecting suction cup 5 to have an autonomous extension and retraction function. This allows the sound-permeable membrane 3 to have a certain buffering effect and adaptability to movement when in contact with the patient's epidermis during use, resulting in better performance.
[0032] One side of the clamping block 17 is connected to a guide groove 2 10, and a guide slider 11 is slidably installed in the guide groove 2 10.
[0033] A tension spring 12 is hinged to the guide slider 11. The other end of the tension spring 12 is hinged to the inner surface of the clearance groove 14. Furthermore, the expansion of the tension spring 12, in conjunction with the guide slider 11, guides the slider to slide along the guide groove 10, thereby keeping the clamping block 17 in place and pressing the edge of the sound-permeable membrane 3. This fixes the edge of the sound-permeable membrane 3 between the inner hook positioning edge 15 and the clamping block 17, improving the stability of the membrane when it is sleeved on the outside of the ultrasonic sleeve 1. This sleeved connection method also facilitates quick disassembly.
[0034] In this embodiment, when the acoustic membrane 3 is fitted onto the outside of the ultrasonic head 1, the inner hook positioning edge 15 and the support edge 16 can limit and position the edge of the acoustic membrane 3, providing excellent positioning and reducing the problem of slippage during the fitting process. Secondly, the expansion of the tension spring 12, combined with the guide slider 11 sliding along the guide groove 10, keeps the pressing block 17 pressing the edge of the acoustic membrane 3, fixing the edge of the acoustic membrane 3 between the inner hook positioning edge 15 and the pressing block 17, improving the stability of fitting onto the ultrasonic head 1. This fitting method also facilitates quick disassembly. The connection suction cup 5 allows the acoustic membrane 3 to adhere well to the surface of the ultrasonic head 1 when fitted onto the ultrasonic head 1, providing pre-positioning and reducing the problem of slippage of the acoustic membrane 3 during fitting and use, which could affect subsequent use.
