Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to an integrated power supply module for anesthesia machines. Background Technology

[0002] The mains power supply for an anesthesia machine is a component of the machine. It is a fundamental part of the anesthesia machine, serving two main functions: first, converting external high-voltage AC power into low-voltage DC power usable by the internal modules; and second, providing a power interface for external devices such as monitors. The mains power supply typically consists of a switching power supply, filters, several sockets, several fuses, and other electrical components arranged in a specific structural layout. Due to the large number of electrical components and the complexity of their interconnections, coupled with space constraints, connecting these components can be challenging. This patent aims to address the technical problem of making the assembly of these electrical components more convenient and efficient.

[0003] In practical applications, the specific assembly method varies depending on the design structure of different anesthesia machines. Generally, a bracket or mounting plate is used to fix these electrical components, then cables are used to connect the pins of these components together, and finally an outer cover is used to protect the connected electrical components. The most difficult part is the second step of connecting the various electrical components together with cables, which generally involves two methods: soldering and plug-in. Soldering involves soldering the cables to the pins. The advantage of this method is a reliable connection that is not easily detached, but the disadvantage is that the process is more complex and the disassembly and maintenance of the electrical components are difficult. Plug-in involves plugging the cables to the pins. The advantage of this method is its simplicity, but the disadvantage is that the connection is not particularly secure and is prone to detachment.

[0004] Whether it's soldering or plugging, traditional connection methods have a drawback: numerous cables. Dozens of cables not only increase the difficulty of operation but also increase the risk of connection errors, affecting the use of the equipment. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the prior art and propose an integrated power supply module for anesthesia machines.

[0006] To achieve the above objectives, this utility model proposes an integrated power supply module for an anesthesia machine, comprising:

[0007] The mains power supply circuit board is used to integrate AC input filters, circuit breakers, power sockets, equipotential grounding terminals, and switching power supplies.

[0008] Mains power supply brackets are used to mount related electrical components and also to mount mains power supply circuit boards; and

[0009] The protective cover connects to the mains power supply bracket and is used to enclose the mains power supply circuit board and related electrical components on the mains power supply bracket, providing protection and shielding.

[0010] Preferably, the power supply circuit board uses a PCB board as the substrate and adopts a double-sided design, so that the neutral wire and the live wire are distributed on both sides of the panel to increase the electrical clearance and creepage distance.

[0011] Preferably, the power supply circuit board is L-shaped, with a filter connection position at the outer right angle, a circuit breaker welding position and a socket connection position respectively at the upper end of the long side of the L-shape, and a power socket welding position and a switching power supply connection position respectively at the short side of the L-shape.

[0012] Preferably, a slot is provided in the horizontal direction on the power supply circuit board adjacent to the circuit breaker soldering position to increase the electrical clearance and creepage distance, which meets the design standards for medical device power supplies.

[0013] Preferably, the circuit breaker is soldered to the mains power circuit board via the circuit breaker soldering position, and the power socket is soldered to the mains power circuit board via the power socket soldering position.

[0014] Preferably, the power supply circuit board is also provided with multiple sockets that support international standards.

[0015] Preferably, the overall circuit layout is as follows: external AC power enters from the power socket, one path passes through the circuit breaker, AC input filter and switching power supply in sequence, and after exiting the switching power supply, it enters the anesthesia machine. The other path is connected to the power socket to supply external power to the anesthesia machine.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This invention significantly reduces the number of cables, lowers the probability of connection errors, and simplifies assembly, making it highly valuable for application and promotion. Attached Figure Description

[0026] 13. Socket Detailed Implementation

[0027] Working principle:

[0028] The overall circuit layout is as follows: external AC power enters from power socket 6, then one path passes through circuit breaker 5, filter, and switching power supply in sequence, and after exiting the switching power supply, it enters the machine's interior. The other path connects to the socket to supply power to the machine's external environment.

[0029] The key innovation of this utility model lies in the introduction of a mains power circuit board 1 as a relay for the interconnection of various electrical components, which reduces the reliance on cable connections for high-voltage sections. The mains power circuit board 1 integrates the AC input filter 4, circuit breaker 5, power socket 6 (supporting various international standard mains power sockets), equipotential grounding terminal, and switching power supply 7, significantly reducing the number of wiring connections. This simplifies the traditional design, making the entire assembly look cleaner, with higher integration and better performance. Simultaneously, slots are created between device signals on the circuit board to increase electrical clearance and creepage distance, ensuring compliance with medical device power supply design standards. An external shielding layer is added to ensure that the switching power supply is not touched and also provides shielding against radiation emissions, resulting in greater safety and reliability.

[0030] The mains power circuit board 1 primarily uses a PCB board as the substrate, employing a double-sided design. Combined with structural support components, this achieves a modular design for the entire mains power assembly. The double-sided design allows the live and neutral wires to be distributed on opposite sides, increasing electrical clearances and creepage distances for enhanced safety and reliability.

[0031] Alternative options include other forms of circuit boards, as well as other electrical components.

[0032] The main technical solution that this utility model aims to protect is an integrated multi-component integrated design.
