Description

Technical Field

[0001] This utility model relates to the field of patient monitoring technology, specifically to an anesthesia depth monitor. Background Technology

[0002] In the design of portable monitoring equipment, balancing structural strength and lightweight design remains a key technical challenge. Traditional monitors typically enhance their impact resistance by increasing the wall thickness of the outer perimeter. While this material-intensive design strategy improves mechanical stability, it inevitably leads to a significant increase in overall weight, making the device bulky and severely limiting its portability and user experience. Especially in clinical settings requiring frequent movement, excessively heavy monitors not only increase the workload for medical staff but also reduce the feasibility of patient self-monitoring. While the industry has attempted to use lightweight material alternatives to reduce weight, these materials often suffer from high costs or insufficient inherent strength. Directly thinning the casing can easily lead to a decrease in structural rigidity, making it difficult to effectively protect internal precision circuit boards under external impact, increasing the risk of equipment failure. Therefore, current technologies have consistently failed to effectively resolve the inherent contradiction between "weight reduction requirements" and "strength assurance."

[0003] Therefore, the inventors proposed an anesthesia depth monitor to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide an anesthesia depth monitor to solve the technical problem that existing monitoring equipment relies on increasing wall thickness, which leads to a contradiction between structural strength and lightweight, and the shell cannot effectively ensure impact resistance while reducing weight.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An anesthesia depth monitor includes a first housing, a second housing, and a circuit board, wherein the circuit board is disposed between the first housing and the second housing;

[0007] The first housing includes a back plate, a first frame, and a first support member. The first frame is fixedly disposed on the back plate, and the first support member is disposed between the back plate and the first frame.

[0008] The second housing includes a panel, a second frame, and a second support member, wherein the panel is connected to the second frame via the second support member.

[0009] According to the above technical solution, in the first housing, the back plate serves as the basic load-bearing component, and the first frame is fixed to its edge to form an outer frame structure. The first support member is set at the connection between the back plate and the first frame, dispersing external impact force through geometric support and avoiding the weight increase caused by traditional thickening of the wall. In the second housing, the panel is connected to the second frame through the second support member, and a stable three-dimensional support network is formed by the spaced arrangement of the support members, which reduces the amount of solid material used while improving the bending and torsional resistance of the housing. The circuit board is sandwiched between the first housing and the second housing, and the safety of the internal electronic components is ensured by the overall rigidity of the housing structure. The first housing and the second housing are assembled by fixing methods such as connecting columns, which further enhances the overall structural stability. Ultimately, the device is lightweight while ensuring impact resistance, effectively solving the contradiction between structural strength and portability in the prior art.

[0010] Furthermore, the first support member includes a plurality of support ribs, each of which is erected at the connection between the back plate and the first frame, with adjacent support ribs spaced apart.

[0011] According to the above technical solution, the first support member achieves a synergy of structural reinforcement and lightweighting through several spaced support ribs: each support rib is fixed to the connection between the back plate and the first frame in an overlapping manner, and its geometric cross-section forms a local reinforcement structure. When an external impact is applied to the shell, the ribs disperse the concentrated stress to a wider range through their own rigidity, avoiding the weight increase caused by traditional thickening of the wall; the spacing design of adjacent ribs forms a hollow area, which reduces the amount of solid material used, and constructs a truss-like mechanical model through the gaps between the ribs, giving the shell connection a higher resistance to bending and torsion; this spaced support structure not only retains the mechanical stability of key connection parts, but also significantly reduces the overall weight of the first shell through material optimization, and ultimately effectively solves the contradiction between "material accumulation for increased weight" and "thinning of the shell to reduce strength" in the prior art while ensuring the impact resistance performance of the shell.

[0012] Furthermore, the second support member includes a plurality of support ribs, one end of which is connected to the panel and the other end of which is connected to the second frame. Adjacent support ribs are spaced apart, and the panel, the second frame, and the two adjacent ribs together enclose a plurality of square slots.

[0013] Furthermore, a plurality of first connecting posts are provided on the side of the panel facing the back plate, and a plurality of second connecting posts are provided on the side of the back plate facing the panel, with the first connecting posts and the second connecting posts corresponding to each other.

[0014] Furthermore, the first connecting post is disposed around the perimeter of the panel and at the center of the panel.

[0015] According to the above technical solution, the connecting columns, as the core fixing points, are evenly distributed around the panel and in the center to form a multi-point support network. When the equipment is subjected to external impact, the central connecting columns can effectively disperse the stress in the core area, while the surrounding connecting columns prevent the shell from deforming by fixing the edges, thus ensuring the overall structural stability. The corresponding connecting columns are tightly connected by screws or snap-fit, which not only avoids the stress concentration caused by local fixing of traditional shells, but also reduces the amount of material used by reducing the number of connection points.

[0016] Furthermore, the middle part of the back plate is recessed outward on the side opposite to the front panel to form a rectangular groove, and a number of reinforcing blocks are provided in the rectangular groove.

[0017] According to the above technical solution, when the equipment is subjected to external impact, the reinforcing block, as a rigid node, can effectively disperse stress and avoid structural weakness caused by material reduction in the recessed area. This design not only reduces the overall weight by utilizing the recess, but also ensures the mechanical stability of the core area through the geometric layout of the reinforcing block, thus achieving an effective balance between weight reduction and impact resistance.

[0018] Furthermore, the back plate has a battery mounting groove recessed inward on the side opposite to the front panel.

[0019] Furthermore, the back plate has slots on both sides, and a plug-in plate is provided in the slot. The slots have engagement notches on both sides, and the plug-in plate has engagement protrusions on both sides, which are adapted to the engagement notches.

[0020] According to the above technical solution, when the plug-in plate is inserted into the slot, the locking protrusions on both sides of the plate engage with the locking notch of the slot, forming a screwless fixation, which simplifies the assembly process and reduces the number of parts. The snap-on design avoids the weight increase caused by traditional screws and ensures the reliability of the connection through mechanical engagement. Users can complete the disassembly and assembly without tools. This structure ensures a stable connection between the back plate and the plug-in components while reducing weight through structural simplification, further optimizing the portability and ease of maintenance of the equipment.

[0021] Furthermore, the back plate is provided with a plurality of mounting posts, and the circuit board is fixed on the back plate by the mounting posts.

[0022] Furthermore, a reinforcing rib is provided between the panel and the second frame.

[0023] The beneficial effects of this utility model are:

[0024] 1. This application constructs a highly efficient geometric support network by setting spaced-apart support ribs at the connection between the back plate and the frame of the first shell, and by using spaced-apart support ribs to form square slots with the panel and frame in the second shell. This design abandons the traditional method of relying on increasing wall thickness to accumulate material. While significantly reducing the amount of solid material used, it effectively improves the bending, torsion, and impact resistance of key connection parts and edge areas of the shell through mechanical optimization distribution. It avoids the risk of reduced rigidity caused by thinning the shell and overcomes the contradiction of increasing the weight of the equipment by increasing the wall thickness. It achieves a significant reduction in the overall weight of the machine while ensuring mechanical stability, fundamentally solving the technical bottleneck of the difficulty in balancing structural strength and lightweight.

[0025] 2. A uniform support network is formed by multi-point distributed connecting columns, combined with targeted reinforcement blocks in recessed areas and a snap-fit ​​connection structure, further optimizing overall performance. The connecting column system can disperse external impact stress, reducing the risk of damage to internal precision components; the rectangular groove in the center of the back plate, combined with the reinforcement block design, achieves localized weight reduction while ensuring the structural strength of the core area; and the snap-fit ​​structure between the slot and the plug-in plate simplifies the assembly process through screwless connection, reducing the number of parts. These designs work together to not only enhance the device's resistance to deformation and impact, but also improve portability and ease of maintenance, making the device both highly reliable and user-friendly in clinical mobile applications.

[0036] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0037] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0038] This embodiment proposes an anesthesia depth monitor, such as... Figures 1 to 8As shown, the device includes a first housing 1, a second housing 2, and a circuit board 3. The circuit board 3 is disposed between the first housing 1 and the second housing 2. It also includes a display screen (not shown), which is mounted on the second housing 2. The first housing 1 includes a back plate 11, a first frame 12, and a first support member 13. The first frame 12 is fixedly disposed on the back plate 11, and the first support member 13 is disposed between the back plate 11 and the first frame 12. The second housing 2 includes a panel 21, a second frame 22, and a second support member 23. The panel 21 is connected to the second frame 22 through the second support member 23.

[0039] In the first housing 1, the back plate 11 serves as the basic load-bearing component, and the first frame 12 is fixed to its edge to form an outer frame structure. The first support member 13 is set at the connection between the back plate 11 and the first frame 12, which increases the structural strength and avoids the weight increase caused by the traditional thickening of the wall. In the second housing 2, the panel 21 is connected to the second frame 22 through the second support member 23. The spaced arrangement of the second support members 23 forms a stable support network, which reduces the amount of solid material used while improving the impact resistance of the second housing 2. The circuit board 3 is set between the first housing 1 and the second housing 2, and the circuit board 3 of the first housing 1 and the second housing 2 ensures the safety of the internal electronic components.

[0040] In a preferred embodiment, the first support member 13 includes a plurality of support ribs 131, each support rib 131 being erected at the connection between the back plate 11 and the first frame 12, with adjacent support ribs 131 spaced apart. Each support rib 131 is fixed to the connection between the back plate 11 and the first frame 12 in an overlapping manner, forming a local reinforcement structure using its geometric cross-section, thereby giving the connection between the back plate 11 and the first frame 12 higher resistance to bending and torsion. This spaced arrangement of support ribs 131 not only maintains the mechanical stability of the connection but also reduces the overall weight of the first shell 1, ultimately effectively resolving the contradiction between "material accumulation increasing weight" and "thinning the shell reducing strength" in the prior art while ensuring the impact resistance of the first shell 1.

[0041] In a preferred embodiment, the second support member 23 includes several support ribs 231. One end of each support rib 231 is connected to the side of the panel 21, and the other end is connected to the second frame 22. Adjacent support ribs 231 are spaced apart, and the panel 21, the second frame 22, and the adjacent support ribs 231 together form several square slots. The square slots formed by the spaced-apart adjacent support ribs 231 and the panel 21 and frame reduce the amount of solid material used. When the shell is subjected to bending or torsional moments, the synergistic effect of the support ribs 231 and the square slots enhances its shear and deformation resistance. This avoids the problem of insufficient strength in traditional structures and overcomes the technical bottleneck that thinning the shell inevitably reduces rigidity. Ultimately, while ensuring the impact resistance of the second shell 2, the overall weight of the equipment is reduced, effectively balancing the contradictory requirements of structural strength and portability.

[0042] In one possible implementation, the square slot can be filled with sealant to improve the sealing properties between the first housing 1 and the second housing 2, so as to prevent water leakage from affecting the internal circuit board 3.

[0043] In a preferred embodiment, a plurality of first connecting posts 24 are provided on the side of the panel 21 facing the back plate 11, and a plurality of second connecting posts 25 are provided on the side of the back plate 11 facing the panel 21. The first connecting posts 24 and the second connecting posts 25 are arranged correspondingly to each other. The first connecting posts 24 are arranged around the perimeter of the panel 21 and in the center of the panel 21. The first connecting posts 24 and the second connecting posts serve as fixed points for connection and are evenly distributed around the perimeter and center of the panel 21 to form a multi-point support network. When the device is subjected to external impact, the first connecting posts 24 and the second connecting posts can also disperse the stress in the impact area and reduce the impact on the internal circuit board 3. The first connecting posts 24 and the second connecting posts 25 arranged around the perimeter are fixed at the edges to prevent the corresponding first housing 1 and second housing 2 from deforming, ensuring the overall structural stability. The corresponding first connecting posts 24 and the second connecting posts 25 are tightly connected by screws or snap-fit.

[0044] In a preferred embodiment, the middle part of the back plate 11 is recessed outward on the side opposite to the front panel 21 to form a rectangular groove 4, and a plurality of reinforcing blocks 41 are provided in the rectangular groove 4. The reinforcing blocks 41 are used to improve the structural strength of the rectangular groove 4 and avoid structural weakness in the recessed area; the geometric layout of the reinforcing blocks 41 ensures the mechanical stability of the core area, and an effective balance is formed between weight reduction and impact resistance.

[0045] In a preferred embodiment, the back plate 11 is recessed inward on the side opposite to the front panel 21 to form a battery mounting groove 5.

[0046] In a preferred embodiment, the back plate 11 has slots on both sides, and a connector plate 6 is disposed in the slot. Engaging notches 61 are provided on both sides of the slots, and engaging protrusions 62 are provided on both sides of the connector plate 6. The engaging protrusions 62 are adapted to the engaging notches 61. When the connector plate 6 is inserted into the slot, the engaging protrusions 62 on both sides engage with the engaging notches 61 of the slot, forming a screwless fixation, simplifying the assembly process and reducing the number of parts. The snap-fit ​​design avoids the weight increase caused by traditional screws and ensures connection reliability through mechanical engagement, allowing users to complete assembly and disassembly without tools. This structure ensures a stable connection between the back plate 11 and the connector while reducing weight through structural simplification, further optimizing the portability and ease of maintenance of the equipment.

[0047] In a preferred embodiment, a plurality of mounting posts 7 are provided on the back plate 11, and the circuit board 3 is fixed to the back plate 11 by the mounting posts 7; a reinforcing rib 8 is also provided between the front panel 21 and the second frame 22, and the two ends of the reinforcing rib 8 are respectively connected to the front panel 21 and the second frame 22. When the equipment is subjected to external force, the reinforcing rib 8 can prevent the front panel 21 from deforming under impact, thereby improving the impact resistance of the internal circuit board 3. The structure is compact and highly practical.
