[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0032] This embodiment describes a spherical restraint device with auditory and tactile stimulation, relating to the field of restraint technology. The hemispherical shell 110 is divided into two parts, forming a quarter shell 111. A portion can be opened as needed to facilitate manipulation and treatment of the patient's hands. Simultaneously, gripping elements 310 are provided within the inner cavities of the two shell plates. Inside the gripping elements 310 is a pressure vibrator 311 or a pressure speech device 312. The pressure vibrator 311 or pressure speech device 312 can actively soothe the patient through voice or vibration, keeping the patient calm and preventing self-harming behavior.

[0033] Please see Figures 1 to 5 This embodiment of a spherical restraint device with auditory and tactile stimulation includes: a spherical restraint component 100, a wrist component 200, and a stimulation and soothing component 300. The spherical restraint component 100 can restrain the patient's palm, the wrist component 200 can bind the patient's wrist, and the stimulation and soothing component 300 can actively soothe the patient, keeping the patient calm and preventing the patient from engaging in self-harming behavior.

[0034] The spherical constraint assembly 100 includes two symmetrically arranged hemispherical shells 110 and a first zipper 120. The two hemispherical shells 110 are connected by the first zipper 120. The two hemispherical shells 110 can be connected and closed or disassembled and opened by the first zipper 120, thus separating the spherical constraint assembly 100 into two parts.

[0035] The hemispherical shell 110 includes two quarter-spherical shells 111 and a second zipper 112. The two quarter-spherical shells 111 are connected by the second zipper 112. The two quarter-spherical shells 111 can be connected and closed or disassembled and opened by the first zipper 120, thus separating the spherical constraint assembly 100 into four parts.

[0036] The first zipper 120 and the second zipper 112 make the entire device easy to disassemble, clean and replace parts, meeting the high hygiene standards required for medical environments.

[0037] The 1 / 4 spherical shell 111 has a ventilation hole 111a, which allows the patient's palm to be ventilated. The patient's palm can move freely, reducing the feeling of restriction, and it can also be ventilated, thus enhancing comfort.

[0038] The wrist assembly 200 includes a wrist pad 210, one end of which is connected to and communicates with the inner cavity of the two hemispherical shells 110. The patient's palm is restrained in the inner cavity of the two hemispherical shells 110, and the patient's wrist is restrained on the wrist pad 210. The wrist pad 210 can prevent the patient's palm from coming out of the spherical restraint assembly 100.

[0039] The stimulation and calming component 300 includes a grasping element 310 disposed within the cavities of the two hemispherical shells 110. When a patient is agitated and struggling, their unconscious grasping behavior can cause them to grip the grasping element 310. The grasping element 310 contains at least one of a pressure vibrator 311 or a pressure voice device 312. The pressure vibrator 311 can be triggered when grasped by external force, generating vibration to distract the patient's attention through tactile stimulation and promote calmness. The pressure voice device 312 can be triggered when grasped by external force, playing pre-recorded audio from a relative to promote calmness through auditory stimulation. The pressure vibrator 311 and pressure voice device 312, through tactile and auditory stimulation, can distract the patient's attention, keeping them calm, preventing self-harming behavior, and proactively reducing the occurrence of injury.

[0040] It should be noted that during use, the patient's hands are restrained by two spherical restraint devices. A pressure vibrator 311 is installed in the gripper 310 of one spherical restraint device, and a pressure speech device 312 is installed in the gripper 310 of the other spherical restraint device. This allows tactile and auditory stimulation to be applied to the patient's two hands respectively, helping the patient remain calm. Alternatively, the spherical restraint devices can be used to restrain only one of the patient's hands (right hand), with both the pressure speech device 312 and the pressure vibrator 311 installed in the gripper 310 of the spherical restraint device. This allows tactile and auditory stimulation to be applied to the patient's only hand simultaneously, helping the patient remain calm.

[0041] In some embodiments, please refer to Figure 1 and Figure 2 The hemispherical shell 110 also includes a connecting part 130, which is located at the intersection of the two quarter shells 111 and the first zipper 120 and is connected to all three respectively, thereby improving the structural strength of the entire spherical restraint device. When the device is closed, the connecting part 130 can disperse the stress at the zipper and prevent the quarter shells 111 and the first zipper 120 from loosening or being damaged due to long-term use or large external force.

[0042] A partition groove is formed between the two quarter-sphere shells 111 and the connecting part 130. The second zipper 112 is connected to the partition groove. The second zipper 112 can connect or separate the hemispherical shells 110, so that the two quarter-sphere shells 111 can be assembled into one or separated into two halves, thereby facilitating the operation of the patient's hand.

[0043] As a further embodiment, the second zipper 112 is positioned perpendicular to the first zipper 120 and parallel to the wrist rest 210. The perpendicular relationship between the second zipper 112 and the first zipper 120 constitutes the two key elements of the closed structure, enhancing the overall closure stability of the device. This perpendicular, intersecting layout effectively distributes the pulling force during closure, reducing structural deformation or damage caused by forces in a single direction.

[0044] For a completely independent embodiment, please refer to Figure 3 To simplify the structure of the spherical constraint component 100, the second zipper 112 can be directly eliminated, so that the spherical constraint component 100 can only be divided into two hemispherical shells 110, thereby enhancing the structural stability of the spherical constraint component 100.

[0045] In some embodiments, the pressure vibrator 311 includes a power supply, a pressure sensor, and a vibration motor, which are electrically connected by wires.

[0046] The pressure sensor detects the pressure applied by the patient's palm to the gripper 310 and judges the patient's emotional or physical state based on changes in pressure, such as increased pressure during anxiety or agitation. The vibration motor generates appropriate vibrational stimulation based on feedback from the pressure sensor, simulating tactile soothing, such as a gentle massage sensation, to distract the patient. Gentle vibrations help relax tense muscles and calm the patient. Tactile stimulation soothes the patient and reduces self-harm behaviors caused by anxiety or agitation, such as pulling out tubes or struggling.

[0047] A power source (such as a rechargeable lithium battery) allows the vibrator to operate independently of an external power system, enabling stable operation over extended periods. The cordless design enhances portability and reduces cable interference with patient movement.

[0048] In some embodiments, the pressure-based voice recorder 312 includes a power supply, a pressure sensor, and a recorder, which are electrically connected via wires. The pressure sensor senses changes in pressure on the patient's palm. When the pressure reaches a set threshold, the recorder begins playing pre-recorded voice. Pre-recorded voices from relatives can reduce triggers for patient agitation, providing the patient with familiar and comforting voices and reducing emotional fluctuations.

[0049] In summary, the pressure vibrator 311 and pressure voice device 312 sense the patient's state through pressure sensors and can automatically trigger vibration or voice soothing functions to provide proactive intervention and avoid potential dangers caused by patient agitation or tension.

[0050] In some embodiments, please refer to Figure 4The gripper 310 includes a gripping body 313 and a third zipper 314. The third zipper 314 is mounted on the gripping body 313 to open and close the inner cavity of the gripping body 313. The pressure vibrator 311 and pressure microphone 312 are both housed within the inner cavity of the gripping body 313. The third zipper 314 allows the inner cavity of the gripping body 313 to be opened and closed, facilitating the installation, adjustment, maintenance, or replacement of the internal pressure vibrator 311 and pressure microphone 312. The gripping body 313 encapsulates the pressure vibrator 311 and pressure microphone 312 internally, preventing the components from being exposed to the external environment (such as dust, liquids, or impacts), effectively protecting the components from external damage, extending the device's lifespan, and ensuring long-term stable operation.

[0051] As a further embodiment, the gripper 313 is pentagonal. The pentagonal shape provides more sides and corners than a circle or ellipse, which helps the patient's palm and fingers obtain more contact points and support when gripping. The polygonal structure can evenly distribute the force of the patient's palm and fingers, improving the stability of the grip.

[0052] Furthermore, the pentagonal grip 313 is closer to the natural curvature of the palm than a circle or square, especially the gripping curve of the fingers. The reasonable distribution of the corners avoids excessive pressure on the palm and fingertips while providing sufficient support.

[0053] In some embodiments, please refer to Figure 5 The wrist assembly 200 also includes a connecting unit 220. The wrist pad 210 has a C-shaped cross-section, which can be fitted onto the patient's wrist for initial positioning and fixation. The end of the wrist pad 210 is connected to the hemispherical shell 110 via a strap. The wrist pad 210 and the hemispherical shell 110 can be freely bent and deformed, giving the hemispherical shell 110 maximum freedom of movement and facilitating relative hand movements.

[0054] The wrist pad 210 has a notch in the length direction, and the connecting unit 220 is disposed at the notch of the wrist pad 210 to adjust the width of the notch. By adjusting the width of the notch, the wrist pad 210 can adapt to the wrist size of different people, making it more compatible and adaptable to the needs of various patients (such as adults, children or different wrist sizes), reducing discomfort or insufficient restraint caused by size mismatch.

[0055] In some embodiments, the connecting unit 220 is a Velcro strap, a cable tie, a buckle strap, or a snap strap.

[0056] When the connecting unit 220 is a hook and loop fastener, the hook and loop fastener includes a hook surface on one side of the C-shaped wrist rest 210 and a strap on the other side of the C-shaped wrist rest 210, with a looped surface on the strap. The looped surface is attached to the hook surface to secure the notch.

[0057] When the connecting unit 220 is a strap, both sides of the C-shaped wrist pad 210 are equipped with straps, and the straps can be knotted to fix the notch.

[0058] When the connecting unit 220 is a buckle strap, the buckle strap includes a female buckle and a buckle strap with a male buckle. The buckle strap is connected to one side of the C-shaped wrist pad 210, and the female buckle is connected to the other side of the C-shaped wrist pad 210. The male buckle can be inserted into the female buckle to fix the notch.

[0059] In some embodiments, the inner wall of the wrist pad 210 is provided with a flexible pad that effectively cushions the direct pressure of hard materials on the skin, providing a soft contact surface. The flexible pad conforms to the curve of the patient's wrist, distributing the pressure applied to the wrist area. At the same time, the flexible pad can reduce discomfort caused by wearing the device, especially during prolonged use, preventing the patient from resisting or becoming agitated due to discomfort.

[0060] The flexible pads also reduce friction between the device and the patient's skin, preventing skin abrasions or ulcers caused by prolonged wear. While applying restraint, the pads evenly distribute pressure, reducing localized pressure and preventing obstructed blood circulation or pressure sores.

[0061] Workflow: First, open the first zipper 120 and connecting unit 220 to expose the cavity between the two hemispherical shells 110. Then, insert the palm into the cavity between the hemispherical shells 110, and place the wrist pad 210 on the wrist. Next, insert the gripper 310 into the palm. Finally, close the first zipper 120 and connecting unit 220 in sequence to complete the restraint of the patient's hands.

[0062] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
