[0033] Please see Figure 1 and Figure 2 This utility model provides a low-power shortwave therapy equipment output power testing device, comprising:

[0034] Induction electrode 1, two induction electrodes 1 are arranged in parallel to sense the electromagnetic field output by the low-power shortwave therapy device and convert the magnetic field into an electric field to supply power.

[0035] The light-emitting element 2 is electrically connected to two sensing electrodes 1 to achieve power supply and light emission;

[0036] The spectral illuminance analyzer 3 is aimed at the light-emitting element 2 to measure its illuminance;

[0037] The adjustable power supply 4 is used to supply power to the light-emitting element 2 in a switchable manner, and the output voltage is adjusted to match the illuminance measured by the spectral illuminance analyzer 3.

[0038] The power meter 5 and the adjustable power supply 4 are electrically connected to the light-emitting element 2 through the power meter 5 and are used to read the output power.

[0039] The working principle of the output power testing device for low-power shortwave therapy equipment of this utility model:

[0040] Two induction electrodes 1 are placed between the capacitive actuators of the low-power shortwave therapy device. After the device is turned on, the electromagnetic field is converted into an alternating electric field by the two induction electrodes 1, illuminating the light-emitting element 2. The illuminance of the light-emitting element 2 is recorded by the spectral illuminance analyzer 3. Then the device is turned off, and the adjustable power supply 4 is switched to power the light-emitting element 2. The voltage is adjusted so that the spectral illuminance is consistent with that when the therapy device is working. At this time, the reading of the power meter 5 is the output power of the device.

[0041] The low-power shortwave therapy equipment output power testing device provided by this utility model has the following significant advantages:

[0042] I. High safety: It adopts a non-contact photoelectric contrast method, which indirectly converts electromagnetic field energy through induction electrodes, avoiding direct contact between operators and high-frequency electromagnetic fields, thus significantly reducing safety risks.

[0043] II. Excellent measurement accuracy: By accurately matching the illuminance with a spectral illuminance analyzer and combining it with a high-precision electric power meter, the output power can be quantitatively measured with an error range of within ±2%, meeting the stringent testing standards for medical equipment.

[0044] III. Simple and reliable structure: It consists of sensing electrodes, light-emitting components and standardized instruments, without complex mechanical or electronic components, which reduces the failure rate and makes it easy to maintain, and the manufacturing cost is low.

[0045] IV. Convenient and efficient operation: No professional radio frequency equipment is required. Calibration can be completed by adjusting the adjustable power supply, which simplifies the operation process, shortens the test time, and is suitable for rapid testing in clinical or production sites.

[0046] V. Strong standardization and compatibility: The design fully complies with the testing requirements of GB 9706.203-2020 for low-power shortwave equipment, ensuring the compliance and authority of the test results.

[0047] This invention achieves comprehensive optimization in terms of safety, accuracy, cost, and operational efficiency through an innovative photoelectric conversion and comparison calibration mechanism, providing an efficient and reliable solution for power detection of low-power shortwave therapy equipment.

[0048] In this embodiment, a switch 6 is provided between the light-emitting element 2 and the power meter 5 to select between the output of the low-power shortwave therapy device and the power supply of the adjustable power supply 4. The switch 6 allows the operator to easily switch between these two modes. During actual measurement, when it is necessary to measure the actual output power of the low-power shortwave therapy device, the switch 6 can be turned off, allowing the two sensing electrodes 1 to power the light-emitting element 2; after turning off the low-power shortwave therapy device, the switch 6 can be closed to connect the adjustable power supply 4. This flexible switching method avoids the tedious operation of frequently disassembling and reconnecting the circuit, greatly improving the efficiency of the measurement work.

[0049] In this embodiment, in order to facilitate the circuit connection of the power meter 5, a socket 7 is installed in the circuit between the switch 6 and the power meter 5, and the wire connected to the power meter 5 is equipped with a plug, which is plugged into the socket 7.

[0050] In this embodiment, the low-power shortwave therapy equipment output power testing device of this invention includes an insulating support frame 8, and two inductive electrodes 1 are fixed to the insulating support frame 8 by insulating brackets. A light-emitting element 2, a switch 6, and a socket 7 are mounted on the insulating support frame 8. This invention uses an insulating support frame 8 to fix the inductive electrodes 1, the light-emitting element 2, the switch 6, and the socket 7. This design effectively avoids leakage during the measurement of the output power of the low-power shortwave therapy equipment, ensuring the personal safety of the operator and the stable operation of the equipment. In actual medical equipment testing scenarios, the measurement of electrical signals is involved. Without a good insulation design, safety accidents such as electric shock may occur. The insulating support frame 8 of this device provides reliable safety assurance for the entire testing process. Fixing the two inductive electrodes 1 to the insulating support frame 8 by insulating brackets, and uniformly mounting the light-emitting element 2, the switch 6, and the socket 7 on the same frame, makes the overall structure of the testing device reasonable and compact. This not only facilitates the carrying and movement of the device, making it convenient for use in different testing sites, but also reduces the space occupied by the device, which has a significant advantage for testing environments with limited space, such as small medical equipment testing laboratories.

[0051] In this embodiment, the sensing electrode 1 is a metal plate, such as an aluminum plate or a copper plate.

[0052] In this embodiment, the light-emitting element 2 is an incandescent bulb with a nominal power of 30-150W and a resistance of 30-150Ω.

[0053] In this embodiment, the adjustable power supply 4 is an AC adjustable power supply, model TDGC2-500W, with an input of AC220V and an output voltage adjustment range of 0-250V. Based on the transformer principle, the output voltage is adjusted by changing the number of turns of the output coil.

[0054] In this embodiment, the power meter 5 is a Hongpin HP-9800 model and has an LED display screen.
