Description

Technical Field

[0001] This invention relates to the field of medical care, and more specifically to a sleep intervention device for hospitalized patients. Background Technology

[0002] Sleep, as an indispensable physiological process for the human body, is a core component for tissue repair, immune function regulation, nerve signal processing, and psychological state reset, and is crucial for maintaining physical and mental health and quality of life.

[0003] For hospitalized patients, a special group, sleep quality often faces multiple threats: on the one hand, from an external perspective, the noise and light interference from medical equipment in the ward, and nighttime medical and nursing procedures, directly disrupt sleep and disrupt melatonin secretion and the biological clock; on the other hand, from an internal perspective, postoperative pain, difficulty breathing, and other physical discomforts, as well as worries about the condition and costs, and a sense of unfamiliarity with the environment, all make it difficult for patients to relax and fall asleep. The combination of these multiple factors results in hospitalized patients generally experiencing short, fragmented, and shallow sleep, seriously affecting treatment and recovery.

[0004] To improve external factors, the focus is usually on improving the sleep of hospitalized patients. Clinically, a series of routine interventions (such as eye masks and earplugs) have been established to help hospitalized patients sleep. Simultaneously, with the development of sleep intervention technology, various sound wave sleep therapy devices are gradually being used in wards. For example, the Juyou Smart Sound Wave Sleep System, Homerion, and Hyundai handheld sound wave sleep aids are already available clinically. These devices are mostly based on the frequency resonance principle of sleep-aiding sound waves such as white noise and pink noise, assisting sleep by masking sudden disturbances and guiding the brain into a relaxed state. However, existing sound wave sleep therapy devices generally use external speakers as the sound wave output carrier, making it difficult to control the sound wave diffusion range. In a hospital environment, when adjusting the volume to a suitable level for a patient's sleep, the diffused sound waves can easily cause auditory interference to other hospitalized patients in the same room. For critically ill patients who are sensitive to sound or are in the postoperative recovery period and require quiet rest, this interference not only disrupts their sleep environment but may also induce emotional problems such as irritability.

[0005] Therefore, the present invention proposes a sleep intervention device for hospitalized patients to solve the above-mentioned problems. Summary of the Invention

[0006] To address the aforementioned issues, this invention provides a sleep intervention device for hospitalized patients, which enables the concentrated output and diffusion blocking of sleep-aiding sound waves. This not only masks environmental disturbances in the ward and guides patients to fall asleep, but also reduces the impact on other patients in the same room, thus adapting to the needs of hospital settings to improve patients' sleep quality.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: a sleep intervention device for hospitalized patients, comprising a bed and a controller, an intervention cover installed at the top of the bed, and a headrest placed inside the intervention cover at the top of the bed; a plurality of sound wave components for generating sounds to intervene in the sleep of hospitalized patients are installed on the inner wall of the intervention cover; the intervention cover consists of an outer layer and an inner layer, and the sound wave components are linearly arrayed on the inner wall of the inner layer along the height direction of the inner layer; the outer layer is made of sound-insulating material.

[0008] The technical principle of the above solution is as follows: This invention achieves functional zoning through the double-layer structure of the intervention cover: the outer layer of sound-insulating material forms a sealed acoustic barrier, which on the one hand blocks external interference sound waves such as the operation of medical equipment and the sound of diagnosis and treatment procedures in the ward from entering the cover, creating a quiet basic environment for patients; on the other hand, it prevents the sleep-aiding sound waves generated by the inner layer of sound wave components from spreading outward, reducing auditory interference to other patients in the same room from the source. The sound wave components linearly arrayed along the height of the inner layer can accurately release sleep-aiding sound waves such as white noise and pink noise to the headrest area, forming a concentrated local sound field to ensure that patients receive sound wave signals efficiently and guide the brain into a relaxed state; at the same time, the array layout can ensure uniform sound wave coverage and improve sleep-aiding comfort.

[0009] The above solution offers the following advantages: Compared to existing technologies, this solution, through the synergistic design of a double-layered intervention shield and linear array acoustic wave components, is well-suited for situations with a large number of patients in hospital settings. The outer layer of sound-insulating material creates a sealed acoustic barrier, achieving bidirectional sound insulation protection. This effectively isolates external interference such as the sound and light from medical equipment and diagnostic procedures within the ward, creating a stable and quiet sleep environment for patients. It also blocks the outward diffusion of sleep-inducing sound waves, reducing auditory interference to other patients in the same room from the source, thus meeting the needs of multi-patient wards.

[0010] Furthermore, each acoustic component includes a sliding groove on the inner wall of the inner layer. Several extrusion chambers are linearly arrayed along the length of the sliding groove. Each extrusion chamber is connected to an extrusion channel on the side away from the sliding groove. Each extrusion channel is connected to an acoustic cavity on the side away from the extrusion chamber. Each acoustic cavity is equipped with a vibration component that is directly opposite to the extrusion channel. Each extrusion chamber is slidably fitted with an extrusion component for squeezing the gas in the extrusion chamber into the acoustic cavity through the extrusion channel. The vibration component is used to induce vibration by squeezing gas flowing into the acoustic cavity through the compression channel, thereby generating specific sound waves for sleep intervention. Each sliding groove is equipped with a sliding component for sliding back and forth within the sliding groove, and the extrusion components are all located within the movement trajectory of the sliding components; when the sliding component slides past a certain extrusion component, the extrusion component slides towards the extrusion channel.

[0011] Beneficial Effects: Based on a double-layer soundproofing enclosure and directional array layout, this solution further enhances its adaptability and sleep-aiding effect in hospital settings through the innovative design of mechanically driven acoustic components. The acoustic components reciprocate along sliding grooves via sliding components, sequentially squeezing the squeezing components within their trajectory. This forces gas from the squeezing chambers into the acoustic chambers through squeezing channels, driving the vibrating components to generate specific sleep-aiding sound waves. Compared to traditional electronic speakers, the sound wave output is gentler and more stable, with no risk of electromagnetic interference, reducing signal interference to medical monitoring equipment in the ward and ensuring treatment safety. Simultaneously, the linearly arrayed squeezing chambers allow for precise control of the sound wave frequency and intensity by adjusting the sliding component's movement speed and squeezing frequency, achieving personalized sleep-aid adaptation. This not only meets the sound wave needs of different patients (such as those experiencing postoperative pain or anxiety) but also enhances the relaxation guidance effect through precise frequency resonance.

[0012] Furthermore, the diameter of the extrusion channel is smaller than the diameter of the corresponding extrusion chamber.

[0013] Beneficial effects: The design of the compression channel diameter being smaller than the compression chamber diameter allows the gas inside the compression chamber to form an accelerated airflow when compressed, achieving concentrated pressure transmission to the sound wave cavity. The high-pressure airflow can more precisely drive the vibration component to vibrate, making the generated sleep-aiding sound wave frequency more stable and the intensity more controllable, improving the targeting and effectiveness of sound wave sleep aid, and ensuring the stability and safety of sound wave output.

[0014] Furthermore, each extrusion assembly includes an extrusion block that slides with the inner wall of the extrusion chamber. Several springs are fixedly connected to the end of the extrusion block near the extrusion channel, and the ends of the springs away from the extrusion block are fixedly connected to the inner wall of the extrusion chamber. The end of the extrusion block near the sliding assembly is a dome structure. Moreover, the extrusion blocks are all located within the movement trajectory of the sliding assembly.

[0015] Beneficial effects: The dome structure reduces the risk of contact friction and jamming during the reciprocating motion of the sliding component, ensuring precise and continuous squeezing action and guaranteeing the continuity and stability of sound wave output; the spring connection design can quickly reset the squeezing block after it is pushed by the sliding component, providing elastic support for the next squeezing, realizing cyclic squeezing and air supply, and adapting to the long-term continuous sleep aid needs in hospital settings.

[0016] Furthermore, each vibration component includes a tuning fork fixedly connected to the inner wall of the acoustic cavity, and each inner top wall of the acoustic cavity is hinged with a striking plate. Each striking plate is located between the corresponding tuning fork and the corresponding compression channel, and each striking plate is directly opposite the corresponding compression channel. Each tuning fork is located within the movement trajectory of the corresponding striking plate.

[0017] Beneficial effects: When the high-pressure airflow impacts the tapping plate, the hinged structure enables a rapid response and reciprocating tapping, driving the tuning fork to generate sleep-aiding sound waves at specific frequencies. The inherent vibration characteristics of the tuning fork ensure that the sound wave frequency is precisely controllable, matching the needs of sleep-aiding frequency bands such as alpha waves and white noise.

[0018] Furthermore, the inner surface of the inner layer is provided with several elastic layers that correspond one-to-one with the sliding grooves.

[0019] Beneficial effects: The inner surface of the inner layer is provided with an elastic layer corresponding to the sliding groove, which can effectively cover the gaps in the sliding groove structure, reduce mechanical friction noise when the sliding component moves, and reduce interference with the patient's sleep; at the same time, the elastic layer can form a physical isolation to prevent the patient's head from accidentally contacting the sliding component or the edge of the groove during sleep, preventing bumps and discomfort, adapting to the sensitive use needs of hospitalized patients, and taking into account both sound field optimization and use safety.

[0020] Furthermore, the inner wall of the acoustic cavity is connected to a balance channel, and the end of the balance channel away from the acoustic cavity extends to the inner surface of the inner layer; the end of the balance channel away from the acoustic cavity is inclined, and the angle between the end of the balance channel away from the acoustic cavity and the top surface of the bed is an acute angle and is oriented away from the sliding groove.

[0021] Beneficial effects: The design of the balanced channel has the dual functions of air pressure balance and gas flow. On the one hand, it can quickly expel the residual high-pressure gas after driving the vibration component in the acoustic cavity, avoid pressure accumulation that hinders the repositioning of the striking plate, and ensure the stability of the frequency and intensity of the sound wave output. At the same time, it promotes gas flow inside the intervention cover and optimizes the local microenvironment. On the other hand, its inclined setting (forming an acute angle with the top surface of the bed and away from the sliding groove) can make the outgoing airflow diffuse away from the patient's head, avoid forming a direct airflow, effectively prevent the patient's head discomfort, and meet the needs of sensitive groups such as postoperative patients and those who are weak.

[0022] Furthermore, each sliding component includes a sliding guide rail disposed within a sliding groove, and the sliding guide rails are distributed along the length direction of the corresponding sliding groove; a sliding sleeve is fitted on each sliding guide rail; and a driving component is provided within each sliding groove for the sliding sleeve to slide back and forth along the sliding guide rail.

[0023] Beneficial effects: The sliding guide provides directional support for the sliding sleeve, effectively reducing movement jamming or offset, ensuring its uniform back-and-forth sliding, making the extrusion component evenly stressed, and ensuring the consistency of the frequency and intensity of the sleep-aiding sound waves.

[0024] Furthermore, each drive component includes a motor disposed inside the sliding sleeve, and each motor output shaft is coaxially fixedly connected to a rolling wheel. Each rolling wheel is located in the corresponding sliding guide rail and slides in cooperation with the corresponding sliding guide rail; each motor is electrically connected to the controller.

[0025] Beneficial effects: The sliding guide provides directional support for the sliding sleeve, effectively reducing movement jamming or deviation, ensuring its uniform back-and-forth sliding, making the extrusion component evenly stressed, and ensuring the consistency of the frequency and intensity of the sleep-aiding sound waves; the drive component realizes automated cyclic drive, adapting to the convenience needs of ward nursing.

[0026] Furthermore, each drive component includes control channels symmetrically arranged at both ends of the sliding groove; it also includes two pump assemblies, with the control channels at both ends of the sliding groove respectively connected to the two pump assemblies; each pump assembly is electrically connected to the controller.

[0027] Beneficial effects: Compared to motor-driven systems, this design eliminates the mechanical vibration and electromagnetic noise generated by motor operation, significantly reducing noise levels and better meeting the core requirement of a low-noise environment in hospital settings. The dual-pump assembly precisely controls the reciprocating motion of the sliding sleeve through a control channel, ensuring smooth and controllable power transmission, uniform force on the compression component, and consistent frequency and intensity of the sleep-aiding sound waves. Simultaneously, its simple structure without complex transmission components facilitates convenient maintenance and reliable operation, further optimizing the sleep intervention experience for hospitalized patients.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The following detailed description illustrates the specific implementation method: Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, a sleep intervention device for hospitalized patients includes a bed 1, a headrest 3, an intervention cover 2, and a controller. The headrest 3 is placed at the top of the bed 1. During the intervention, the hospitalized patient's head is placed on the headrest 3, and then the intervention cover 2 surrounds the patient's head and is placed on the bed 1, forming a relatively independent space. Simultaneously, the intervention cover 2 is equipped with several sound wave components for generating sounds (such as white noise) to intervene in the hospitalized patient's sleep. The intervention cover 2 consists of an outer layer 202 and an inner layer 201, and the outer layer 202 is made of sound-insulating material (such as polyurethane foam).

[0035] Specifically, in combination Figure 2 , Figure 3 and Figure 6As shown, each acoustic component includes a sliding groove 401 opening into the inner wall of the inner layer 201. The sliding grooves 401 are linearly arrayed (arc-shaped) along the height direction of the inner layer 201 on the inner wall of the inner layer 201, and all sliding grooves 401 are horizontally arranged. Several elastic layers 4, corresponding one-to-one with the sliding grooves 401, are provided on the inner surface of the inner layer 201. Several extrusion cavities 601 opening into the inner layer 201 are linearly arrayed along the length direction of the sliding grooves 401 on the inner wall of the inner layer 201. Figure 4 As shown, each extrusion chamber 601 has an extrusion channel 602 connected to its right end, and the diameter of each extrusion channel 602 is smaller than the diameter of the corresponding extrusion chamber 601. Each extrusion channel 602 has an acoustic cavity 7 connected to its right end. Each acoustic cavity 7 has a striking piece 702 hinged to its inner top wall, which is directly opposite to the extrusion channel 602. Each acoustic cavity 7 has a tuning fork 701 screwed to its inner wall. Each striking piece 702 is located between the corresponding tuning fork 701 and the extrusion channel 602, and each tuning fork 701 is located within the movement trajectory of the corresponding striking piece 702. At the same time, each extrusion chamber 601 has an extrusion block 6 slidably fitted to its inner wall. Each extrusion block 6 has several springs welded to its right end, and the right ends of the springs are welded to the inner wall of the extrusion chamber 601. Each extrusion block 6 has a dome structure on its left end.

[0036] Combination Figure 7 and Figure 8 As shown, each sliding groove 401 is provided with a sliding guide rail 501 distributed along the length direction of the corresponding sliding groove 401. Each sliding guide rail 501 is fitted with a sliding sleeve 5. Each sliding groove 401 is provided with a driving component for the sliding sleeve 5 to slide back and forth along the sliding guide rail 501. The extrusion block 6 is located within the movement trajectory of the sliding sleeve 5.

[0037] Secondly, combining Figure 3 and Figure 5 As shown, the inner wall of the acoustic cavity 7 is connected to a balance channel 703. The end of the balance channel 703 away from the acoustic cavity 7 extends to the inner surface of the inner layer 201. The end of the balance channel 703 away from the acoustic cavity 7 is inclined. The angle between the end of the balance channel 703 away from the acoustic cavity 7 and the top surface of the bed body 1 is an acute angle (30-60°) and it is oriented away from the sliding groove 401.

[0038] Specifically, each drive component includes a motor disposed inside the sliding sleeve 5, and each motor output shaft is coaxially screwed with a rolling wheel. Each rolling wheel is located in the corresponding sliding guide rail 501 and slides in cooperation with the corresponding sliding guide rail 501. Each motor is electrically connected to the controller.

[0039] The specific implementation process is as follows: The patient's head is placed on the headrest 3, and the head is surrounded by the intervention cover 2 and fixed to the bed frame 1, forming a two-way soundproof space constructed of the outer layer of 202 polyurethane foam sound insulation material. This not only blocks external ward noise from entering, but also reduces subsequent sound wave leakage that may disturb other patients in the same room. Subsequently, medical staff preset the sleep-aiding sound wave parameters (such as frequency and intensity) through the controller. After activation, the controller sends drive signals to each motor, and the motor output shaft drives the rolling wheel in the sliding guide rail 501 to slide back and forth at a uniform speed along the sliding guide rail 501.

[0040] Thus, the sliding sleeve 5 moves synchronously with the rolling wheel, and the outer wall of the sliding sleeve 5 continuously contacts the dome structure of the extrusion block 6 in the sliding groove 401. The dome design effectively reduces friction and jamming, allowing the sliding sleeve 5 to smoothly extrude each extrusion block 6. Figure 4 As shown, after being pushed, the squeezing block 6 slides to the right along the squeezing cavity 601, compressing the right-end spring and pushing the gas in the squeezing cavity 601 into the squeezing channel 602. Since the diameter of the squeezing channel 602 is smaller than that of the squeezing cavity 601, the gas flows through and forms a high-pressure accelerated airflow, achieving concentrated pressure transmission. After the high-pressure airflow rushes into the sound wave cavity 7, it precisely impacts the hinged striking plate 702, causing the striking plate 702 to swing rapidly around the hinge point and repeatedly strike the tuning fork 701. The tuning fork 701 generates sleep-aiding sound waves of a preset frequency (such as 8-13Hz alpha waves, white noise, etc.) based on its inherent vibration characteristics. The linearly arrayed tuning forks 701 ensure that the sound waves are directionally and evenly covered in the headrest 3 area, forming a concentrated local sound field, which guides the patient's brain into a relaxed state through frequency resonance.

[0041] After the compression block 6 completes a single compression, the elastic restoring force of the spring pushes the compression block 6 back to its initial position quickly, preparing for the next compression and ensuring the continuity of sound wave output. At the same time, the residual high-pressure gas in the sound wave cavity 7 after driving the striking plate 702 is quickly discharged through the balance channel 703. The channel design, with an acute angle of 30-60° and oriented away from the sliding groove 401, avoids the airflow directly blowing on the patient's head and causing discomfort, while also promoting air circulation within the intervention cover 2, maintaining a comfortable local microenvironment, and preventing stuffiness inside the inner layer 201. The elastic layer 4 on the inner surface of the inner layer 201 corresponds one-to-one with the sliding groove 401. On the one hand, it covers the gap between the grooves to reduce mechanical friction noise, and on the other hand, it isolates the patient's head from the sliding sleeve 5 to avoid bumps and discomfort.

[0042] Secondly, combining Figure 7As shown, the outer surface of the sliding sleeve 5 is made of flexible silicone and designed with an arc-shaped fitting structure. When the sliding sleeve 5 moves back and forth along the sliding guide rail 501, it simultaneously acts as a massage end, maintaining gentle contact with the patient's scalp and continuously rolling and massaging. The regular vibrations transmitted by the mechanical transmission stimulate acupoints on the scalp, promoting blood circulation in the head and relieving scalp muscle tension caused by anxiety and fixed posture during hospitalization. This works synergistically with the sleep-aiding sound waves generated by the tuning fork 701: the sound waves guide the brain to relax through frequency resonance, while the massage relieves physical tension through physical stimulation. This dual intervention mechanism further enhances the relaxation effect on the patient's head, helping the patient fall asleep more quickly. At the same time, the elastic layer 4 on the inner surface of the inner layer 201 can buffer the contact pressure between the sliding sleeve 5 and the scalp, avoiding local pressure discomfort and ensuring a gentle and safe massage process. This is suitable for the tolerance needs of postoperative, weak, and other hospitalized patients, further enhancing the overall sleep intervention effect of the device. However, it is not suitable for patients with head trauma.

[0043] Example 2: The difference from Example 1 is that this example also provides a driving component, combined with... Figure 9 As shown, each drive component includes control channels 8 symmetrically arranged at both ends of the sliding groove 401; it also includes two pump assemblies. The control channel 8 at the left end of the sliding groove 401 is connected to one pump assembly, and the control channel 8 at the right end of the sliding groove 401 is connected to the other pump assembly. The pump assemblies are preferably silent air pumps (with built-in exhaust valves, such as the Aotes 600W-50L), and the connection ports between the pump assemblies and the control channels 8 are located on the surface of the outer layer 202. The remaining structure is the same as in Embodiment 1, and the pump assemblies are all electrically connected to the controller. Compared to the motor drive in Embodiment 1, the pneumatic method avoids the electromagnetic noise and mechanical vibration noise generated by the motor operation, further reducing the operating noise of the equipment and thus ensuring the stability of the intervention sound waves within the intervention cover 2. Simultaneously, the pneumatic drive provides uniform and gentle thrust, allowing for precise adjustment of the sound wave parameters through accurate control of the airflow pressure, improving equipment adaptability.

[0044] The specific implementation process is as follows: After medical staff preset the sleep-aiding sound wave parameters through the controller, the controller controls the two air pumps to alternately start and stop and control the airflow direction according to the parameter instructions. When the sliding sleeve 5 needs to move to the right, the controller starts the left air pump and shuts off the right air pump. The exhaust valve of the right air pump is opened, and the airflow generated by the left air pump is injected into the left end of the sliding groove 401 at a constant speed through the left control channel 8, forming a positive thrust on the left end face of the sliding sleeve 5, pushing the sliding sleeve 5 to slide smoothly to the right along the sliding guide rail 501. When the sliding sleeve 5 moves to the preset position at the right end of the sliding groove 401, the controller triggers the left air pump to stop inflating and opens the exhaust valve of the left air pump. At the same time, the right air pump is started, and the airflow generated by the right air pump is injected into the right end of the sliding groove 401 through the right control channel 8, forming a reverse thrust on the right end face of the sliding sleeve 5, pushing the sliding sleeve 5 to reset to the left along the sliding guide rail 501. Through the cyclical alternation of inflation and deflation of the two air pumps, the sliding sleeve 5 can slide back and forth continuously and at a constant speed along the sliding guide rail 501, and the sliding speed can be precisely controlled by adjusting the airflow of the pump assembly.

[0045] During the reciprocating motion of the sliding sleeve 5, the contact and extrusion process between the outer wall of the sliding sleeve 5 and the dome structure of the extrusion block 6, the subsequent sound wave generation, the exhaust through the balance channel 703, and the protective function of the elastic layer 4 are all consistent with those in Example 1. This example, driven by pneumatics, further reduces the operating noise of the equipment while retaining the original sleep aid function and sound insulation effect.

[0046] Example 3: The difference from Example 2 is that, in combination Figure 3 As shown, this solution can also be connected to an arc-shaped adaptive sound-insulating airbag at the left end of the intervention cover 2 (the expansion degree can be adjusted by an air pump or air inflator to fit different patients according to the size of their necks). The sound-insulating airbag is set around the patient's neck, and the air volume can be adjusted to achieve a close fit with the neck, thereby providing targeted sealing and sound insulation treatment for the unsealed area at the left end of the intervention cover 2. This effectively blocks the leakage of sleep-aiding sound waves inside the cover and the entry of external environmental noise into the intervention cover 2, further reducing interference to other patients in the same ward and enhancing the independence of the local sound field and the sound insulation effect.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
