Description

Technical Field

[0001] This utility model relates to the field of medical monitoring technology, and in particular to a sound-generating structure and an anesthesia depth monitor. Background Technology

[0002] Anesthesia depth monitors are widely used medical devices in anesthesiology and surgical departments. Their main function is to monitor the patient's physiological parameters and compare them with known set values. If any parameters are exceeded, an alarm is issued promptly. Medical staff can accurately calculate and observe the patient's depth of anesthesia using anesthesia depth monitors, thereby better controlling the patient's anesthetic state during surgery.

[0003] During anesthesia and surgery, the loudspeaker, as a key component of the monitor, can remind medical staff whether the patient's anesthesia depth is lower than the set value by emitting sound, ensuring that medical staff can complete the surgical operation based on accurate data during anesthesia and surgery.

[0004] Currently, the sound transmission structure of common monitor speakers is not good, which may cause medical staff to be unable to receive alarm signals in a timely and accurate manner in complex environments such as operating rooms, leading to serious surgical accidents and posing a great threat to the patient's life. Utility Model Content

[0005] The main purpose of this invention is to propose a sound-generating structure and an anesthesia depth monitor, which aims to improve the sound transmission effect of the monitor.

[0006] To achieve the above objectives, the sound-generating structure proposed in this utility model includes:

[0007] The housing has multiple annular layers arranged in concentric circles, with the radii of each annular layer increasing sequentially; each annular layer has multiple sound outlets, and the sound outlets on each annular layer are evenly distributed circumferentially.

[0008] A fixing plate, the fixing plate being connected to the housing and enclosing the housing to form a sound chamber communicating with each of the sound-emitting holes; and

[0009] The speaker is mounted on the fixed plate and located in the sound cavity.

[0010] In one embodiment, the sound outlets in two adjacent annular layers are staggered.

[0011] In one embodiment, the smaller the radius of the annular layer, the smaller the diameter of each of the sound outlet holes formed in the annular layer.

[0012] In one embodiment, the fixing plate forms a limiting hole, and a portion of the horn structure passes through the limiting hole and abuts against the hole wall.

[0013] In one embodiment, the fixing plate further forms an installation channel that communicates with the limiting hole.

[0014] In one embodiment, the width of the mounting channel gradually decreases along the direction of the mounting channel toward the limiting hole.

[0015] In one embodiment, the sound-generating structure further includes a support ring disposed on the housing, and a fixing plate disposed on the side of the support ring facing away from the housing; the housing, the support ring, and the fixing plate together form the sound chamber.

[0016] In one embodiment, the sound-generating structure further includes a buffer pad, which is sleeved on the outer peripheral wall of the speaker, and the side of the buffer pad facing away from the speaker abuts against the inner wall of the support ring.

[0017] In one embodiment, the cushioning pad is made of silicone.

[0018] This utility model also proposes an anesthesia depth monitor, including a monitoring device and any of the above-mentioned sound-generating structures, wherein the speaker is electrically connected to the monitoring device, and the monitoring device is used to monitor the patient's physiological parameters.

[0019] In the technical solution of this utility model, the sound-generating structure includes a shell, a fixing plate, and a speaker. The shell has multiple annular layers, each arranged concentrically, with the radius of each annular layer increasing sequentially. Each annular layer forms multiple sound outlets, which are evenly distributed circumferentially on each annular layer. The fixing plate connects to the shell and encloses a sound cavity communicating with each sound outlet. The speaker is mounted on the fixing plate and located within the sound cavity. In this technical solution, the multiple annular layers and the evenly distributed sound outlets on each layer enable the sound emitted by the speaker to propagate evenly in all directions, avoiding sound concentration in one direction and thus improving the sound propagation effect in complex environments such as operating rooms. By optimizing the structure of the sound outlets, the emitted sound is clearer, reducing noise and interference, and maintaining high energy during sound propagation, thereby improving sound propagation efficiency and ensuring that medical personnel can receive alarm signals promptly and accurately.

[0032] This utility model proposes a sound-generating structure 100.

[0033] Please see Figure 1 , Figure 2 as well as Figure 3 In one embodiment of the present invention, the sound-generating structure 100 includes a housing 1, a fixing plate 2, and a speaker 3. The housing 1 has multiple annular layers, each annular layer is arranged in concentric circles, and the radius of each annular layer increases sequentially. Each annular layer forms multiple sound outlet holes 1a, and each sound outlet hole 1a on each annular layer is evenly distributed circumferentially. The fixing plate 2 is connected to the housing 1 and forms a sound chamber communicating with each sound outlet hole. The speaker 3 is disposed on the fixing plate 2 and located in the sound chamber.

[0034] In the technical solution of this utility model, multiple annular layers are set up, and the sound outlet holes 1a on each layer are evenly distributed circumferentially. This enables the sound emitted by the speaker 3 to propagate evenly in all directions, avoiding the sound from being concentrated in one direction, thereby improving the sound propagation effect in complex environments such as operating rooms. By optimizing the structure of the sound outlet holes 1a, the emitted sound can be clearer, reducing noise and interference, and maintaining high energy during sound propagation, thereby improving the sound propagation efficiency and ensuring that medical staff can receive alarm signals in a timely and accurate manner.

[0035] Please see Figure 3 and Figure 4In one embodiment of this utility model, the sound outlets 1a in two adjacent annular layers are staggered. This arrangement allows the sound outlets 1a on the housing 1 to be distributed outward in a spiral shape. The spiral design of the sound outlets 1a reduces interference and attenuation of sound during propagation, making the sound clearer and more focused, improving the sound propagation efficiency, and ensuring that medical personnel can receive alarm signals in a timely and accurate manner. At the same time, the spiral design of the sound outlets 1a allows the sound to form a longer propagation path during propagation, thereby extending the sound propagation distance and enabling the sound to travel further in complex environments, ensuring that medical personnel can clearly receive alarm signals even at a greater distance.

[0036] In one embodiment of this invention, the smaller the radius of the annular layer, the smaller the diameter of each sound outlet 1a formed in the annular layer. Sound outlets 1a with different diameters can produce sounds of different frequencies, thereby optimizing the frequency response of the sound, making the sound more uniform in different frequency ranges, and improving the sound's recognizability.

[0037] Please see Figure 1 , Figure 2 as well as Figure 5 In one embodiment of this utility model, the fixing plate 2 forms a limiting hole 2a, and a portion of the horn 3 is inserted into the limiting hole 2a and abuts against the wall of the limiting hole 2a. By inserting a portion of the horn 3 into the limiting hole 2a and abutting against the wall of the hole, the position of the horn 3 can be effectively fixed, preventing the horn 3 from loosening or shifting during use, thereby improving the stability of the sound-generating structure 100. The design of the limiting hole 2a provides precise positioning for the horn 3, ensuring that the horn 3 can be accurately installed in the predetermined position during assembly, improving assembly accuracy. The design of the limiting hole 2a makes the disassembly of the horn 3 more convenient, facilitating maintenance and replacement, simplifying the disassembly process, improving maintenance efficiency, and reducing maintenance costs.

[0038] In one embodiment of this utility model, the fixing plate 2 further forms an installation channel 2b, which connects to the limiting hole 2a. The design of the installation channel 2b makes the installation of the speaker 3 more convenient. Part of the speaker 3 can be inserted into the limiting hole 2a through the channel, thereby avoiding the need to disassemble the fixing plate 2 to complete the installation of the speaker 3, which simplifies the assembly process. The design of the installation channel 2b makes the structure of the fixing plate 2 more compact, saves space, and helps to reduce the volume of the entire sound-generating structure 100, making it more suitable for use in limited spaces.

[0039] In one embodiment of this invention, the width of the mounting channel 2b gradually decreases along the direction from the mounting channel 2b toward the limiting hole 2a. This gradual decrease in the width of the mounting channel 2b allows for progressive alignment of the speaker 3 assembly during installation, helping to ensure that the speaker 3 is accurately positioned within the limiting hole 2a.

[0040] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 In one embodiment of this utility model, the sound-generating structure 100 further includes a support ring 4, which is disposed on the housing 1, and a fixing plate 2 is disposed on the side of the support ring 4 facing away from the housing 1; the housing 1, the support ring 4, and the fixing plate 2 enclose and form a sound chamber. The support ring 4 provides additional support for the fixing plate 2, enhancing the stability of the entire sound-generating structure 100 and improving its durability; at the same time, the support ring 4 supports the fixing plate 2, making the sound chamber formed by the fixing plate 2 and the housing 1 larger, thereby enhancing the sound propagation force and enabling the sound to propagate more effectively to a greater distance.

[0041] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the sound-generating structure 100 further includes a buffer pad 5, which is sleeved on the outer peripheral wall of the speaker 3. The side of the buffer pad 5 facing away from the speaker 3 abuts against the inner wall of the support ring 4. The buffer pad 5 can buffer the collision between the speaker 3 and the support ring 4, thereby reducing the impact damage to the speaker 3 caused by long-term use. At the same time, the buffer pad 5 helps to improve the sealing of the acoustic chamber, reduce sound leakage, and thus improve the sound transmission efficiency and clarity.

[0042] The buffer pad 5 can be made of rubber, silicone, or other elastic materials. In one embodiment of this invention, the buffer pad 5 is made of silicone. The silicone buffer pad 5 provides better cushioning, reducing vibration and impact on the speaker 3 during operation, thereby protecting the speaker 3 and extending its service life. The silicone buffer pad 5 also helps improve the sealing of the acoustic chamber, reducing sound leakage and thus improving sound transmission efficiency and clarity. Therefore, silicone is preferred as the material for the buffer pad 5.

[0043] This utility model also proposes an anesthesia depth monitor, which includes a monitoring device and a sound-generating structure 100. The specific structure of the sound-generating structure 100 is as described in the above embodiments. Since this anesthesia depth monitor adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The speaker 3 is electrically connected to the monitoring device, which is used to monitor the patient's physiological parameters.

[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
