Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a power failure alarm device for medical equipment. Background Technology

[0002] Medical equipment refers to instruments, equipment, appliances, materials or other items used alone or in combination on the human body, and also includes the necessary software. Medical equipment is the most basic element of medical, scientific research, teaching, institutional and clinical work, including both professional medical equipment and home medical equipment.

[0003] For example, the power failure protection alarm device for medical equipment disclosed in Chinese Patent No. CN222483862U works as follows: "It includes a main body of the equipment, a protective box on top of the main body, an alarm and a buzzer on the right side of the protective box, and the interior of the protective box includes: a conductive component, which includes a magnetic block, an iron end on top of the magnetic block, a base below the magnetic block, and a power-conducting component, which includes a socket, with a plug for connecting to the buzzer below the socket. This invention, by setting up a conductive component, ensures that when the main body of the equipment experiences an abnormal power failure, the magnetic block loses its magnetic force, thereby..." "By detaching from the magnetic end, the plug can be quickly moved into the socket, energizing the alarm and buzzer, and causing them to sound an alarm to notify the device of a power outage." Its triggering mechanism relies primarily on the magnetic block's attraction and release of the magnetic end. However, this process is susceptible to external environmental interference. Vibrations generated during device operation may cause the magnetic end to jam or shift during movement, preventing accurate insertion of the plug into the socket. This renders the alarm function ineffective and fails to provide timely warnings of power outages, posing a potential risk to the normal operation of the medical equipment. Utility Model Content

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0013] Please see Figure 1-3 This utility model provides a technical solution: a power failure alarm device for medical equipment, including a medical instrument 10. The power input of the medical instrument 10 is provided with a housing 11. An alarm 12 is fixedly installed on the top of the housing 11. The alarm 12 is provided with a display panel 13 on the side of the housing 11. An insertion port 14 is provided on the side of the housing 11. An installation compartment 20 is fixedly installed inside the housing 11. An installation slot 21 is opened inside the installation compartment 20. A trigger component for power failure is provided inside the installation slot 21. A control component for controlling power switching is provided inside the installation slot 21. The trigger component and the control component are electrically connected by wires.

[0014] In this implementation scheme, key components such as the alarm 12, display panel 13, and socket 14 are integrated into the outer casing 11, which facilitates observation and operation by the operator. The installation compartment 20 and installation slot 21 provide a stable installation environment for the internal triggering and control components, ensuring that the components will not loosen or shift due to external interference during operation, thus improving the reliability and stability of the device. The triggering and control components are electrically connected by wires, so that the power failure trigger signal can be transmitted to the control component in a timely and accurate manner, achieving rapid response and issuing early warnings to medical personnel. The rapid response achieved by the triggering component is not affected by external interference and has high reliability, providing a strong guarantee for the safe operation of the medical instrument 10 in the event of a power failure.

[0015] Specifically, the control components include a backup power supply 22 and a power switch 23. The backup power supply 22 is fixedly installed on one side inside the mounting slot 21, and the power switch 23 is fixedly installed on the side of the backup power supply 22 inside the mounting slot 21. The power switch 23 is electrically connected to the backup power supply 22 and the socket 14 through wires.

[0016] In this embodiment, the design of the backup power supply 22 and power switch 23 in the control component ensures that when the main power supply is working normally through the socket 14, the power switch 23 can ensure that the main power supply powers the medical instrument 10. Once the main power supply fails, the power switch 23 can quickly and automatically switch the power to the backup power supply 22, so that the medical instrument 10 can continue to operate normally for a short time. This avoids problems such as data loss, equipment damage or treatment interruption caused by sudden power failure, greatly improving the safety and continuity of the use of the medical instrument 10. At the same time, this design is simple and reliable, easy to maintain and manage, and reduces the cost of use.

[0017] Specifically, the triggering components include a control chamber 24, a permanent magnet 25, and an electromagnet 28. The control chamber 24 is fixedly installed on one side of the power switch 23. The permanent magnet 25 is movably installed inside the control chamber 24. A circuit board 26 is installed at the upper end of the control chamber 24. A Hall sensor 27 is installed below the circuit board 26. The electromagnet 28 is fixedly installed at the bottom inside the control chamber 24. The circuit board 26 is electrically connected to the backup power supply 22 through wires. Guide components are installed on both sides of the permanent magnet 25 on the inner wall of the control chamber 24.

[0018] In this embodiment, the triggering component adopts a combination design of permanent magnet 25, electromagnet 28, and Hall sensor 27 to achieve triggering in the event of a power outage. When the main power supply is on, electromagnet 28 is energized and generates magnetism, attracting permanent magnet 25 and causing it to move away from Hall sensor 27. At this time, Hall sensor 27 has no signal output. When the main power supply is off, electromagnet 28 loses magnetism, and permanent magnet 25 moves closer to Hall sensor 27 under the force of the guide component. Hall sensor 27 detects the change in magnetic field and outputs a signal, thereby triggering subsequent alarm and power switching actions. This triggering method has high sensitivity and fast response speed, can detect power outage in a timely and accurate manner, and has a simple structure, high reliability, and is not easily affected by external environmental interference. The setting of the guide component ensures the stability of permanent magnet 25 during movement, further improving the accuracy of triggering.

[0019] Specifically, the guiding assembly includes a guide rod 31, a spring 32, and a connecting block 33. Movable grooves 30 are provided on both sides of the permanent magnet 25 on the inner wall of the control chamber 24. The guide rod 31 is fixedly installed inside the movable groove 30. The spring 32 is sleeved on the lower periphery of the guide rod 31. The connecting block 33 is movably sleeved on the upper periphery of the guide rod 31. The connecting block 33 is fixedly connected to the permanent magnet 25.

[0020] In this embodiment, the guide rod 31 in the guide assembly provides guidance for the movement of the permanent magnet 25, ensuring that the permanent magnet 25 can only move along a specific direction, avoiding deviation or jamming of the permanent magnet 25 during movement, thereby ensuring that the Hall sensor 27 can accurately detect the position change of the permanent magnet 25, improving the reliability and stability of the trigger assembly. The spring 32 plays a role in buffering and resetting. When the electromagnet 28 attracts the permanent magnet 25, the spring 32 is compressed, providing elastic force for the permanent magnet 25 to reset after the main power is cut off, so that the permanent magnet 25 can move accurately with the movement of the guide rod 31.

[0021] Specifically, the outer casing 11 has a standard interface on the other side of the socket 14.

[0022] In this embodiment, a standard interface is specially configured on the outer casing 11, which can seamlessly adapt to various types of devices. Through this standard interface, the power failure alarm device can establish a stable connection with various devices, thereby providing accurate and timely power failure warnings for these devices and effectively ensuring the safe and stable operation of the devices in complex power environments.

[0023] During use, firmly insert the external power cord into the socket 14 on the side of the outer casing 11, and then connect the medical instrument 10 to it stably through the standard interface. At the same time, check whether the backup power supply 22 has sufficient power. Under normal power supply, the main power supply is supplied through the socket 14. The power switch 23 automatically switches to the main power supply to power the medical instrument 10. The electromagnet 28 in the control compartment 24 is energized to attract the permanent magnet 25 away from the Hall sensor 27. The Hall sensor 27 has no signal output, and the display panel 13 shows that the main power supply is on and the alarm 12 is silent. Once the main power supply is cut off, the power switch 23 detects that the electromagnet 28 has lost its magnetism. Under the elastic force of the guide component spring 32, the permanent magnet 25 moves up along the guide rod 31 and approaches the Hall sensor 27. The Hall sensor 27 detects the change in magnetic field and outputs a signal. After receiving the signal, the control component triggers the alarm 12 to emit an alarm sound and light prompt. The display panel 13 updates to the main power supply being cut off and the backup power supply 22 being on. At the same time, the power switch 23 quickly and automatically switches the power supply to the backup power supply 22 to power the medical instrument 10, ensuring its continued operation.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
