Description

Technical Field

[0001] The utility model relates to the technical field of therapeutic instruments, in particular to a medium frequency therapeutic instrument with a noise reduction function. Background Art

[0002] The medium frequency therapeutic device connects a pulsed electrical signal of a certain voltage and frequency to the human body through electrodes. Since many components of human tissue have certain electrical properties, when electrically stimulated, the muscles, nerves, body fluids and blood of the human body will produce a certain degree of physical and chemical reactions.

[0003] When a medium frequency therapeutic device is in use, the therapeutic device body is usually placed on a table. Medical staff hold the electrode patches connected to the therapeutic device body in their hands and contact the human body to treat the patient. The therapeutic device will generate noise during use, so a rubber pad is set at the lower end of the therapeutic device body for soft contact with the table, which effectively reduces the transmission of contact noise between the therapeutic device body and the table. However, the rubber pad is prone to wear due to long-term use and needs to be replaced in time. The traditional installation method of the rubber pad is that the rubber pad fixed to the therapeutic device by screws is inconvenient to replace, and the rubber pad fixed to the therapeutic device body is prone to natural falling off and has a low service life.

[0007] The connecting member includes a rectangular frame, a sliding plate slidably arranged inside the rectangular frame and a threaded column fixedly arranged at the lower end of the therapeutic device body. A threaded hole matching the threaded column is opened in the middle of the sliding plate, and the lower end surface of the sliding plate is connected to a connecting plate through a damper.

[0008] As a further description of the above technical solution:

[0009] The noise reduction component comprises a mounting plate and a rubber sleeve. The mounting plate is fixedly arranged at the lower end of the connecting plate. Both sides of the mounting plate are symmetrically provided with slots for mounting the rubber sleeve.

[0010] As a further description of the above technical solution:

[0011] A rubber pad is arranged at the upper end of the interior of the rectangular frame, and a placement groove for installing the rubber pad is opened on the upper end surface of the rectangular frame.

[0013] There are multiple dampers, which are symmetrically mounted on the end surface of the connecting plate.

[0014] As a further description of the above technical solution:

[0015] The rubber sleeve is made of polyurethane rubber material.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] In the utility model, by providing a mounting plate, a slot and a rubber sleeve, the rubber sleeve is inserted into the slot under the action of its own elasticity to achieve stable installation of the rubber sleeve, which is not easy to fall off naturally. At the same time, the rubber sleeve can be directly peeled off and removed from the mounting plate for subsequent replacement, and installation and disassembly are relatively convenient.

[0018] In the utility model, by arranging a sliding plate, a rectangular frame, a threaded column, a damper and a connecting plate, it is convenient to disassemble the rectangular frame from the therapeutic instrument body, that is, to disassemble the mounting plate fixedly connected to the connecting plate, so that the staff can install or disassemble the rubber sleeve on the outside of the therapeutic instrument body conveniently, so that during the use of the therapeutic instrument, vibrations of a certain frequency will be buffered by the damper, effectively reducing the noise generated during the vibration process.

[0019] In the utility model, a rubber pad is provided for the contact between the rectangular frame and the lower end surface of the therapeutic instrument, thereby achieving a soft contact protection effect and effectively preventing the rectangular frame from contacting the lower end surface of the therapeutic instrument during installation, thereby causing scratches and wear on the surface of the therapeutic instrument.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] As shown in 1-3, a medium frequency therapeutic device with a noise reduction function comprises a therapeutic device body 1, a display screen 2 and a plurality of operation keys 3 respectively arranged on the surface of the therapeutic device body 1, a plurality of connectors evenly distributed on the lower end surface of the therapeutic device body 1, and a noise reduction component 4 is arranged at the lower end of the plurality of connectors;

[0027] The connecting part includes a rectangular frame 7, a sliding plate 6 slidably arranged inside the rectangular frame 7 and a threaded column 5 fixedly arranged at the lower end of the therapeutic instrument body 1. A threaded hole matching the threaded column 5 is opened in the middle of the sliding plate 6. The lower end surface of the sliding plate 6 is connected to a connecting plate 9 through a damper 8. The sliding plate 6 is threadedly connected to the threaded column 5 for installation. The installation connection of the sliding plate 6 is limited until the contact between the rectangular frame 7 and the lower end surface of the therapeutic instrument is limited, thereby ensuring the uniformity of the installation height of the sliding plate 6. During the use of the therapeutic instrument, the vibration generated by the frequency will be buffered by the damper 8, effectively reducing the external noise generated during use.

[0028] Furthermore, the noise reduction component includes a mounting plate 401 and a rubber sleeve 402. The mounting plate 401 is fixedly arranged at the lower end of the connecting plate 9. Both sides of the mounting plate 401 are symmetrically provided with card slots 403 for mounting the rubber sleeve 402. The rubber sleeve 402 is directly and stably clamped on the card slot 403, that is, it is stably mounted on the outer side of the mounting plate 401. When the therapeutic device is placed, the lower surface of the rubber sleeve 402 will contact the desktop, which has the same noise reduction effect as the traditional method of setting a rubber pad on the lower end surface of the therapeutic device. The rubber sleeve 402 is convenient to install and disassemble, and is not easy to fall off naturally after installation.

[0029] Furthermore, there are multiple dampers 8 which are symmetrically mounted on the upper end surface of the connecting plate 9, thereby effectively improving the buffering effect.

[0030] Furthermore, the rubber sleeve 402 is made of a polyurethane rubber material, which has high strength and elasticity, can maintain high elasticity within a wide hardness range, and has excellent wear resistance.

[0032] As shown in 1-3, a rubber pad 10 is provided at the upper end of the rectangular frame 7, and a placement groove for installing the rubber pad 10 is opened on the upper end surface of the rectangular frame 7. By providing the rubber pad 10, the rectangular frame 7 is used to contact the lower end surface of the therapeutic device, thereby achieving a soft contact protection effect, thereby avoiding hard contact between the rectangular frame 7 and the therapeutic device, which may cause scratches and wear on the surface of the therapeutic device.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
