Description

Technical Field

[0001] This invention relates to the field of restraint bed technology, and more particularly to an artificial intelligence restraint bed for patients with mental disorders. Background Technology

[0002] During the acute phase, patients with mental disorders often experience self-harm, harm to others, or fall out of bed due to hallucinations and delusions. Restraint, as a protective nursing measure, can reduce harm and ensure the smooth implementation of treatment. However, the limb restriction and skin pressure caused by restraint can trigger physiological stress responses. Combined with the cognitive biases and sense of loss of control caused by the disease, patients often exhibit instinctive struggling behaviors.

[0003] Existing restraint beds mostly use mechanical restraint structures with fixed force, which cannot be dynamically adjusted and further reinforced when the patient struggles. This can easily lead to the loosening of the restraints, the patient breaking free and causing safety incidents. Furthermore, manual tightening has a response delay and is difficult to deal with sudden and violent struggles. Therefore, it cannot meet the core requirements of dynamic clinical protection. In view of this, the present invention is proposed. Summary of the Invention

[0012] Furthermore, a guide rod is fixedly connected to the bottom of the bed board, a support plate is provided at the bottom of the guide rod, a second stepper motor is provided at the bottom of the support plate, a lead screw is provided at the output end of the second stepper motor, and extension plates are fixedly provided on both sides of the connecting block.

[0013] Furthermore, the bed board and mattress are provided with multiple through holes, and the first partition, the second partition and the leg straps are all slidably disposed in the through holes.

[0014] Furthermore, the pressure threshold of the first pressure sensor is set. Set the tension threshold of the tension sensor. Within 10 seconds, when the number of action events N detected by the first pressure sensor or tension sensor is greater than or equal to 2, the first and second partitions are driven to move downwards, and gas is injected into the airbag component at the same time. The action event is defined as the value of the first pressure sensor being greater than or equal to the pressure threshold.

[0015] Compared with existing technologies, the present invention provides an artificial intelligence restraint bed for patients with mental disorders, which has the following beneficial effects: 1. This artificial intelligence restraint bed for patients with mental disorders uses a restraint plate that is directly fastened to the second partition during restraint. The restraint effect is achieved through the pad and airbag components. When the patient struggles violently, the restraint plate is pushed, applying tension to the tension sensor. Simultaneously, the patient's back impacts the mattress after struggling, applying pressure to the first pressure sensor. Based on the values ​​on the tension and first pressure sensors, the first and second partitions are controlled to move downwards, allowing the restraint plate, pad, and airbag components to enhance the compression restraint effect on the patient, increasing the restraint force and reducing the patient's struggling. Once the patient's struggling subsides, the first and second partitions are gradually reset to maintain the initial restraint effect, preventing injury to the patient.

[0016] 2. This artificial intelligence restraint bed for patients with mental disorders uses leg straps to fix the patient's legs. When the patient struggles, pressure is applied to the second pressure sensor, and then the second stepper motor controls the movement of the connecting block, thereby pulling the leg straps downward to improve the restraint effect on the patient's legs. When the patient becomes stable, the connecting block can be reset again for easy reuse.

[0017] 3. This artificial intelligence restraint bed for patients with mental disorders assists in their work by setting tension and pressure thresholds. When the value of the first pressure sensor is greater than or equal to the pressure threshold, or the value of the tension sensor is greater than or equal to the tension threshold, the restraint can be directly increased to improve the restraint effect.

[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention can dynamically adjust and further strengthen the fixation strength when the patient struggles, preventing the restraint effect from loosening and the patient from breaking free. It does not require manual tightening and can cope with sudden violent struggles, meeting the core requirements of dynamic clinical protection. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Example 1: Refer to Figures 1-10 An artificial intelligence restraint bed for patients with mental disorders includes a bed board 1 and a mattress 101 mounted on the bed board 1. It also includes a first partition 2 and a second partition 3 inserted into the bed board 1 and the mattress 101. A restraint plate 201 is rotatably connected to the first partition 2, and the end of the restraint plate 201 away from the first partition 2 is connected to the second partition 3. A pad 202 is provided at the bottom of the restraint plate 201, and an airbag 203 is provided at the bottom of the pad 202. Two sets of fixing rods 4 are provided at the bottom of the restraint plate 201, respectively located on both sides of the pad 202, and an arc-shaped pressure plate 403 is connected to the bottom of each set of fixing rods 4. A fixing plate 501 is also fixedly mounted at the bottom of the bed board 1, and tension sensors 504 are provided between the fixing plate 501 and the bottom of the first partition 2 and the second partition 3. A first pressure sensor 102 is located between the bed board 1 and the mattress 101.

[0024] In this embodiment, during use, the patient lies on the mattress 101 with their torso positioned between the first partition 2 and the second partition 3. Two sets of the first and second partitions 2 and 3 are provided; one set secures the patient's chest, and the other secures the lower abdomen, enhancing the restraint effect. During restraint, the restraint plate 201 is directly fastened to the second partition 3, and the restraint effect is achieved through the pad 202 and the airbag 203. When the patient struggles violently, they will push the restraint plate 201, causing the first and second partitions 2 and 3 to move or shake. The tension sensor 504 will detect the tension. On the other hand, when the patient struggles and his back hits the mattress 101, it will press the first pressure sensor 102. Then, based on the values ​​on the tension sensor 504 and the first pressure sensor 102, the first partition 2 and the second partition 3 will be controlled to move downward, so that the restraint plate 201, the pad 202 and the airbag 203 can improve the compression restraint effect on the patient and increase the restraint force, thereby reducing the patient's struggling force. When the patient's struggling becomes less intense, the first partition 2 and the second partition 3 will be gradually reset to maintain the initial restraint effect and avoid injuring the patient.

[0025] Meanwhile, if the values ​​on the first pressure sensor 102 and the tension sensor 504 are large, air is injected into the airbag component 203 through an external air supply device to make it expand, so that the expanded airbag component 203 further improves the restraint effect on the patient. After the patient calms down, the components are slowly reset to avoid pressure injury caused by prolonged use.

[0026] Example 2: Refer to Figure 4- Figure 7 An artificial intelligence restraint bed for patients with mental disorders is basically the same as in Embodiment 1. Furthermore, a connecting plate 301 is provided between the first partition 2 and the second partition 3, and a first stepper motor 502 is provided at the bottom of the fixing plate 501. The first stepper motor 502 is connected to the first pressure sensor 102 and the tension sensor 504. A connecting rod 5 is connected between the fixing plate 501 and the bottom of the bed board 1.

[0027] Reference Figures 4-7 The connecting plate 301 is provided with a round hole 302 and a limiting groove 303. The output end of the first stepper motor 502 is provided with a threaded rod 503. A threaded cylinder 304 is threadedly connected to the threaded rod 503. The threaded cylinder 304 is slidably connected in the round hole 302. A limiting block 305 corresponding to the limiting groove 303 is fixedly provided on the outer wall of the threaded cylinder 304. Limiting rings 306 are fixedly provided at both the upper and lower ends of the threaded cylinder 304.

[0028] In this embodiment, when the values ​​on the first pressure sensor 102 and the tension sensor 504 are large, a signal is sent to start the first stepper motor 502, causing it to drive the threaded rod 503 at the output end to rotate. The threaded rod 503 is threadedly connected to the threaded cylinder 304, which can drive the threaded cylinder 304 to start moving. Under the action of the limiting groove 303 and the limiting block 305, the threaded cylinder 304 can be limited, so that it will not rotate with the rotation of the threaded rod 503, but will only move under the action of the threaded connection of the threaded rod 503. The provided circular hole 302 and limiting groove 303 can make the movement of the threaded cylinder 304 more stable. When the limiting ring 306 on 304 moves to abut against the top outer wall of the connecting plate 301, it can continuously press the connecting plate 301 with the continuous rotation of the threaded rod 503. This causes the connecting plate 301 to drive the first partition 2 and the second partition 3 to move slightly downward, making the connection between the restraint plate 201 and the patient tighter and improving the restraint effect. It should be noted that the threaded rod 503 rotates less, so that the connecting plate 301 will not have a large displacement, which can improve the protection of the patient. The small displacement can significantly improve the restraint effect. At the same time, the cooperation of the airbag component 203 makes the restraint effect even better.

[0029] Reference Figure 6The bottom of the first partition 2 and the second partition 3 are provided with a rod 507. The bottom of the rod 507 is provided with a round block 508. The top of the tension sensor 504 is provided with a fixing block 505. The fixing block 505 is provided with a round groove 506. The round block 508 is placed in the round groove 506 and abuts against the top inner wall of the round groove 506.

[0030] In this embodiment, when the connecting plate 301 pulls the first partition 2 and the second partition 3 to move, it will drive the insertion rod 507 and the round block 508 to move, so that the round block 508 slides in the round groove 506, providing a certain amount of movement space for the first partition 2 and the second partition 3, avoiding damage to the tension sensor 504. In the initial state, the round block 508 abuts against the top inner wall of the round groove 506, so when the patient struggles, it can better realize the feedback of the tension sensor 504.

[0031] Reference Figures 1-5 The first partition 2 is provided with a connecting groove 207, and a connecting pipe 206 connected to the airbag component 203 is provided in the connecting groove 207. The constraint plate 201 is provided with a U-shaped plate 204 that is engaged with the second partition 3. Both the U-shaped plate 204 and the second partition 3 are provided with corresponding limiting holes 205.

[0032] Reference Figure 4 and Figure 5 A cylinder 401 is fixedly installed on the arc-shaped pressure plate 403. A fixing rod 4 is inserted into the cylinder 401, and a first elastic element 402 is provided between the fixing rod 4 and the inner wall of the cylinder 401. A sponge pad 404 is provided on the bottom of the arc-shaped pressure plate 403.

[0033] In this embodiment, while the restraint plate 201 restrains the patient, the arc-shaped pressure plate 403 can restrain the patient's arm. On the two sets of restraint plates 201, one set can restrain the patient's upper arm, and the other set can restrain the patient's wrist, improving the restraint effect. Specifically, when the restraint plate 201 is fastened, the arc-shaped pressure plate 403 will directly abut against the patient's arm. At the same time, a sponge pad 404 is provided at the bottom of the arc-shaped pressure plate 403, which can improve the protection effect on the patient's arm. In addition, a first elastic element 402 is provided inside the cylinder 401, which can further slightly cushion the arc-shaped pressure plate 403 and further protect the patient's hand. The first elastic element 402 is specifically a spring or a spring sheet, etc.

[0034] Example 3: Refer to Figures 1-3 and Figures 8-10An artificial intelligence restraint bed for patients with mental disorders is basically the same as in Embodiment 2. Furthermore, the bed board 1 and the mattress 101 are also provided with leg straps 6. A connecting block 601 is slidably provided at the bottom of the bed board 1. The connecting block 601 is provided with a recess. Both ends of the leg straps 6 are inserted into the recess and connected to a sliding plate 606. A second pressure sensor 608 is also provided on the inner wall of the recess. A second elastic element 607 is provided between the upper and lower sides of the sliding plate 606 and the inner wall of the recess.

[0035] Reference Figures 8-10 A guide rod 605 is fixedly connected to the bottom of the bed board 1. A support plate 603 is provided at the bottom of the guide rod 605. A second stepper motor 609 is provided at the bottom of the support plate 603. A lead screw 604 is provided at the output end of the second stepper motor 609. An extension plate 602 is fixedly provided on both sides of the connecting block 601. The lead screw 604 is threadedly connected to the extension plate 602, and the extension plate 602 is slidably mounted on the guide rod 605. A second pressure sensor 608 is signal-connected to the second stepper motor 609.

[0036] Reference Figure 1 and Figure 3 The bed board 1 and the mattress 101 are provided with multiple through holes 103, and the first partition 2, the second partition 3 and the leg straps 6 are all slidably disposed in the through holes 103.

[0037] In this embodiment, during restraint, the patient's legs pass through the leg straps 6 and are fixed by the leg straps 6. When the patient struggles, the leg straps 6 are pulled, which in turn moves the sliding plate 606. Multiple second elastic elements 607 are provided at both the upper and lower ends of the sliding plate 606 to increase the resistance of the sliding plate 606 and improve the restraint effect of the leg straps 6. If the patient struggles with great force, the leg straps 6 will pull the sliding plate 606 and press the second pressure sensor 608. If the pressure received by the second pressure sensor 608 is large, it will send a signal to start the second stepper motor 609, which will drive the lead screw 604 at its output end to rotate. The lead screw 604 is threadedly connected to the extension plate 602, which can drive the extension plate 602 to move, thereby driving the connecting block 601 to move, which in turn pulls the leg straps 6 downward, improving the restraint effect on the patient's legs. When the patient becomes stable, the connecting block 601 can be reset again for easy reuse.

[0038] Example 4: Refer to Figures 1-10 An AI-assisted restraint bed for patients with mental disorders is essentially the same as in Embodiment 3, but further includes setting pressure thresholds for the first pressure sensor 102 and the second pressure sensor 608. Set the tension threshold of the tension sensor 504. Within 10 seconds, when the number of action events N detected by the first pressure sensor 102 or the tension sensor 504 is greater than or equal to 2, the first partition 2 and the second partition 3 are driven to move downwards, and gas is injected into the airbag component 203. Specifically, when the above situation occurs, the first pressure sensor 102 or the tension sensor 504 will send a signal, thereby causing the first stepper motor 502 to start working. The threaded rod 503 drives the threaded cylinder 304 to move downwards, causing the limiting ring 306 at the top of the threaded cylinder 304 to drive the connecting plate 301 to move downwards, thereby pulling the first partition 2 and the second partition 3 to move, thereby increasing the squeezing force between the restraint plate 201 and the patient and improving the restraint effect. At the same time, air is injected into the connecting pipe 206 through the external air supply device, thereby causing the airbag component 203 to expand, and the expanded airbag component 203 further improves the restraint effect on the patient. After the patient calms down, the components are slowly reset to avoid pressure injuries caused by prolonged use.

[0039] The action event is defined as the value of the first pressure sensor 102 being greater than or equal to the pressure threshold. And the duration is ≥0.5s, or the value of the tension sensor 504 is ≥ the tension threshold. And the duration is ≥0.5s.

[0040] The pressure threshold is calculated as follows:

[0041] in, Indicates the pressure threshold, in units of To avoid pressure injury, the value range is [value range missing]. The severity coefficient indicates the severity of the illness: 1.2 for severe mania / schizophrenia, 1.0 for moderate illness, and 0.8 for mild illness. The coefficient representing the correlation between weight and stress is set to 0.05, as the constraints in this application are primarily for adult use. ; This indicates the patient's actual weight, in units of... ; This represents the safety redundancy factor, which is set to 0.9 to prevent excessive pressure.

[0042] The tensile threshold is calculated as follows:

[0043] in, Indicates the tensile threshold, in units of To accommodate different patients, the value range is 5-50. ; The severity coefficient indicates the severity of the illness: 1.2 for severe mania / schizophrenia, 1.0 for moderate illness, and 0.8 for mild illness. This represents the correlation coefficient between body weight and tensile force. The constraint in this application is mainly for adult use, and is set to 0.3 for adults. ; This indicates the patient's actual weight, in units of... ; This represents the safety redundancy factor, which is set to 0.9 to prevent excessive strain.

[0044] Within a sliding time window of T=10s, the number of action events is counted. Constraint tightening is triggered when the following conditions are met:

[0045] Triggering condition is .

[0046] Secondly, it should be noted that when the value of the second pressure sensor 608 is greater than or equal to the pressure threshold... If the duration is ≥0.5s, a signal is sent to drive the second stepper motor 609 to start, thereby causing it to move the threaded extension plate 602, which in turn moves the connecting block 601, increasing the clamping force between the leg strap 6 and the patient's leg, thus restraining the patient during struggle.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
