Description

Technical Field

[0001] This utility model relates to the field of psychiatric medical devices, specifically a reclining and sitting integrated bed and chair for psychiatric patients. Background Technology

[0002] Patients with mental symptoms refer to those whose brain function is disordered due to various harmful external factors. Clinically, they are people with abnormal mental activity, specifically manifested as varying degrees of impairment in perception, thinking, attention, memory, emotion, behavior, will, intelligence, and consciousness. Due to the impairment of mental activity, patients reflect objective reality in a distorted way, lose their ability to adapt to society, or harm themselves or disrupt social order. These individuals are collectively referred to as patients with mental symptoms.

[0003] Chinese patent CN202222277763.3 discloses an adjustable restraint chair, belonging to the field of psychiatric medical devices. The adjustable restraint chair includes a restraint chair with multiple restraint straps A fixedly installed on it. An adjustment mechanism connects the leg rest and the backrest. The adjustment mechanism includes H-shaped rods, each end of which is rotatably connected to an L-shaped rod. A support assembly is connected to the backrest. When the bolts are not connected to the limiting seats, rotating the backrest causes the leg rest to rotate at the same angle through the cooperation of the L-shaped rods and H-shaped rods. This allows the device to easily switch between a sitting and lying position, facilitating elderly patients to change positions between the restraint chair and the hospital bed. It is simple to operate, has good stability, and high safety.

[0004] Based on the aforementioned existing technologies, it has been found that mental patients with different conditions have different risks of self-harm or harming others, requiring restraints of varying intensities. Existing three-fold bed-chair restraint devices are difficult to flexibly adjust the tightness and intensity of the restraints according to the specific condition of the patient. If the restraints are too loose, the patient may break free, causing a safety accident; if the restraints are too tight, they will restrict the patient's normal limb movements, causing physical discomfort, or even damaging the skin and muscles.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Please see Figure 1-16 A psychiatric patient restraint reclining / sitting integrated bed-chair includes a bed frame structure 1. A support component 3 is hinged to one side of the bed frame structure 1. The support component 3 and the bed frame structure 1 are used for the patient to lie down. A restraint component 2 is provided on the surface of the bed frame structure 1 for restricting the patient's limbs. The bed frame structure 1 includes a first seat board 101. A connecting frame 103 is provided at the bottom of the first seat board 101. A slide rod 105 is provided on the outer surface of the connecting frame 103. A mattress 102 adapted to the first seat board 101 is provided on its surface. The support assembly 3 includes a load-bearing frame 301. One side of the load-bearing frame 301 is hinged to the connecting frame 103. The bottom of the load-bearing frame 301 is provided with a placement plate, and the surface of the placement plate is provided with a first motor 305. The output end of the first motor 305 is fixedly provided with a first transmission wheel 306, and the outer surface of the first transmission wheel 306 is provided with a transmission belt 304. The first transmission wheel 306 is connected to a second transmission wheel 307 through the transmission belt 304. The side of the second transmission wheel 307 away from the transmission belt 304 is fixedly provided with a second wheel 303.

[0046] like Figure 1-3As shown, the bottom of the support frame 301 is provided with a first wheel 302. The first motor 305 drives the first drive wheel 306 and the second drive wheel 307 simultaneously through the transmission belt 304. There are two of each of the following: the first motor 305, the transmission belt 304, the first drive wheel 306, and the second drive wheel 307. Each of these components is symmetrically arranged at the bottom of the support frame. The bed frame structure 1 also includes a second bed board 106 and a mattress 102. One side of 6 is hinged to the load-bearing frame 301, and the bottom of the second bed board 106 and the first bed board 101 are respectively hinged to a first support rod 104 and a second support rod 107. The first support rod 104 and the second support rod 107 are used to support the first bed board 101 and the second bed board 106 respectively. The height of the first support rod 104 and the second support rod 107 is adapted to the support frame. There are multiple mattresses 102, and each mattress 102 is located above the first bed board 101, the second bed board 106 and the load-bearing plate.

[0047] Specifically, the first wheel 302 at the bottom of the load-bearing frame 301, together with the second wheel 303, forms the moving support point of the bed-chair. The presence of the first wheel 302 increases the contact area between the bed-chair and the ground, improving the stability of the bed-chair during movement and reducing the risk of swaying or tipping over. To ensure the smooth movement of the bed-chair, a design of two symmetrically arranged first motors 305, transmission belts 304, first transmission wheels 306, and second transmission wheels 307 is adopted. Each first motor 305 works independently, and the transmission belt 304 simultaneously drives the corresponding first transmission wheel 306 and second transmission wheel 307, making the power output on both sides of the bed-chair uniform and avoiding deviations or jamming in the movement direction of the bed-chair due to uneven power. The second bed board 106 in the bed frame structure 1 is hinged to the load-bearing frame 301. According to the patient's needs, the second bed board 106 can be rotated around the hinge point to adjust its relative position and angle with the first bed board 101. When the patient needs to lie down, the second bed board 106 can be adjusted to a position roughly flush with the first bed board 101 to form a larger lying surface. When the patient needs to sit up, the second bed board 106 can be adjusted to a suitable tilt angle to provide support for the patient's back. Furthermore, the bottom of the first bed board 101 and the second bed board 106 are respectively hinged with a first support rod 104 and a second support rod 107. When the second bed board 106 and the first bed board 101 are adjusted to a suitable angle, the first support rod 104 and the second support rod 107 can play a supporting role. Their length and angle are adapted to the height of the support frame to ensure that a stable triangular support structure is formed when supporting the bed board.

[0048] like Figure 4 , Figure 7 and Figure 8 As shown, the constraint assembly 2 includes a first slider 211 and a second slider 212. Two of each type are provided, and each slider 211 and slider 212 has a locking member on the side facing the slide rod 105. Each slider 211 and slider 212 is slidably disposed inside the slide rod 105 via the locking member, and each slider 211 and slider 212 is slidably disposed on the outer surface of the slide rod 105. The slide rod 105 controls the sliding of the second slider 212 via a second electric actuator, and the second electric actuator is... On the outer surface of the slide bar 105, each first slider 211 is provided with a first electric push rod 213 at its top, and each first electric push rod 213 is provided with a fixing block on its outer surface. One side of each fixing block is provided on the surface of the connecting frame 103. The first slider 211 and the second slider 212 are respectively provided with a first restraint band 214 and a second restraint band 215. The first restraint band 214 and the second restraint band 215 extend outward to the outer surface of the mattress 102. The first restraint band 214 and the second restraint band 215 are used to restrict the patient's upper limb area.

[0049] Specifically, when restraining the upper limbs of psychiatric patients, when medical staff need to restrain the patient's upper limbs, the second electric actuator is operated to apply a pushing force to the second slider 212, causing the second slider 212 to move on the slide rail according to a preset trajectory. Secondly, the top of the first slider 211 is provided with a first electric actuator 213, and the outer surface of the first electric actuator 213 is provided with a fixing block, and one side of the fixing block is set on the surface of the connecting frame 103. The function of the first electric actuator 213 is to adjust the height of the first slider 211 to adapt to different patients' physical conditions and restraint needs. The fixing block firmly connects the first slider 211 to the connecting frame 103, ensuring the stability of the first slider 211 during operation and preventing it from shaking or shifting due to the patient's struggle or movement.

[0050] The first slider 211 and the second slider 212 are respectively equipped with a first restraint band 214 and a second restraint band 215 inside. These two restraint bands extend outward to the outer surface of the mattress 102. When the second slider 212 moves under the control of the slider 105, it will drive the second restraint band 215 to move, thereby changing the position and tightness of the restraint band. Medical staff can precisely adjust the position of the restraint band according to the specific condition of the patient's upper limb, so that it can tightly wrap around the patient's upper limb area, achieving effective restriction of the patient's upper limb. In psychiatric wards, some patients may experience emotional agitation and loss of control due to unstable mental state, and their upper limbs may make some dangerous movements, such as attacking others or harming themselves. This restraint method also has high precision and adjustability, and can be adjusted according to the actual situation of the patient, reducing unnecessary restraint and harm to the patient. Through the cooperation of these components, the function of flexibly and precisely restraining the patient's upper limb is achieved, thereby solving the problem of uncontrollable movements of the upper limbs of psychiatric patients.

[0051] The restraint assembly 2 also includes a first restraint chamber 205, which is provided with a hand restraint strap 204 inside. The number of first restraint chambers 205 and hand restraint straps 204 is set to two, and each first restraint chamber 205 and hand restraint strap 204 are symmetrically arranged on the left and right sides of the load-bearing frame 301.

[0052] Specifically, when restraining the hands of psychiatric patients, the first restraint compartments 205 and hand restraint straps 204, symmetrically arranged on both sides of the load-bearing frame 301, play a crucial role. The first restraint compartments 205 provide a safe and orderly storage space for the hand restraint straps 204. When the hand restraint straps 204 are not needed, they can be neatly stored inside the first restraint compartments 205, preventing damage or loss due to random placement. At the same time, the first restraint compartments 205 also provide some protection for the hand restraint straps 204, preventing them from being exposed to dust, moisture, and other environmental factors. Due to the influence of factors, each first restraint chamber 205 and the hand restraint strap 204 are symmetrically arranged on the left and right sides of the load-bearing frame 301. This symmetrical design has many advantages. On the one hand, it ensures that the restraint effect on the patient's hands is consistent. When restraining the patient's hands, the hand restraint straps 204 on both sides can apply restraint force simultaneously and evenly, avoiding discomfort or poor restraint effect caused by uneven restraint. On the other hand, the symmetrical arrangement also facilitates the operation of medical staff. When performing hand restraint, medical staff can operate on the patient's hands at the same time, improving work efficiency.

[0053] When it is necessary to restrain a patient's hands, medical staff simply need to take out the hand restraint strap 204 from the first restraint compartment 205, wrap it around the patient's hand, and secure it appropriately. The material and design of the hand restraint strap 204 usually take into account the patient's comfort and safety, for example, using soft, breathable materials to avoid harming the patient's skin. At the same time, the fixing method of the restraint strap is designed to be both secure and easy to operate, ensuring the restraint effect while allowing medical staff to easily adjust or release the restraint at any time. Through this combination of the first restraint compartment 205 and the hand restraint strap 204, the function of effectively restraining the hand is achieved, thereby further solving the problem of uncontrolled hand movements that may occur in psychiatric patients, and providing more comprehensive protection for psychiatric nursing work.

[0054] like Figure 5 As shown, a leg restraint strap 206 is provided through the surface of the second bed 106. The end of the leg restraint strap 206 is located inside the second restraint chamber 208. An installation plate 207 is fixedly provided on the outer surface of the second restraint chamber 208. The installation plate 207 is fixedly located on one side of the second bed 106. There are two of each of the leg restraint strap 206, the second restraint chamber 208 and the installation plate 207. Each leg restraint strap 206, the second restraint chamber 208 and the installation plate 207 are symmetrically arranged on the left and right sides of the second bed 106. Each leg restraint strap 206 restricts the patient's lower limbs through the second restraint chamber 208.

[0055] Specifically, when restricting the lower limbs of psychiatric patients, the leg restraint straps 206, the second restraint compartment 208, and the mounting plate 207 on the second bench 106 work together to play an important role. The leg restraint straps 206 are provided through the surface of the second bench 106, and the ends of the leg restraint straps 206 are located inside the second restraint compartment 208. The second restraint compartment 208 not only provides storage space for the leg restraint straps 206, but also allows for certain management and protection of the leg restraint straps 206.

[0056] Two leg restraint straps 206, two second restraint compartments 208, and two mounting plates 207 are provided, each symmetrically positioned on the left and right sides of the second bed 106. This symmetrical arrangement ensures uniform restraint on the patient's legs. When restraining the patient's lower limbs, the leg restraint straps 206 on both sides can simultaneously and evenly apply restraining force to the patient's legs, avoiding discomfort or slippage caused by uneven restraint. Each leg restraint strap 206 restrains the patient's lower limbs through the second restraint compartment 208. When it is necessary to restrain the patient's lower limbs, medical staff pull out the leg restraint strap 206 from the second restraint compartment 208, wrap it around the patient's legs, and secure it appropriately. The fixation method of the leg restraint strap 206 is usually designed to be both secure and easy to operate. It can ensure the restraint effect while allowing medical staff to adjust or release the restraint at any time. During psychiatric nursing, patients' lower limbs may exhibit uncontrolled movements, such as kicking or thrashing. This not only affects the patient's own safety but may also cause harm to surrounding facilities and personnel. Through the cooperation of the leg restraint strap 206, the second restraint compartment 208, and the mounting plate 207, medical staff can promptly and effectively restrain the patient's lower limbs, ensuring the safety and stability of the nursing environment and achieving the function of effectively restraining the patient's lower limbs. This solves the problem of uncontrolled movements of the lower limbs in psychiatric patients.

[0057] like Figure 9 and Figure 10 As shown, both the first restraint chamber 205 and the second restraint chamber 208 are fixedly equipped with a central shaft 217 inside. Each central shaft 217 has a rotatable storage shaft 216 on its outer surface. Each central shaft 217 has a first torsion spring at its end, which is used to reset the storage shaft 216. The outer surface of each storage shaft 216 is connected to one end of the hand restraint strap 204 and the leg restraint strap 206, respectively. The other ends of the hand restraint strap 204 and the leg restraint strap 206 respectively pass through the first restraint chamber 205. The first constraint chamber 205 and the second constraint chamber 208 are provided with elastic plates 218 inside, and each elastic plate 218 is rotatably provided with a drive rod 219 on the outer side. Each drive rod 219 passes through the first constraint chamber 205 and the second constraint chamber 208 respectively through a limiting groove 220. The inner wall of the first constraint chamber 205 and the second constraint chamber 208 near the drive rod 219 is provided with a return spring, and the two return springs are used to reset the two drive rods 219 respectively.

[0058] Specifically, regarding the storage and release of the restraint straps, both the first restraint compartment 205 and the second restraint compartment 208 are equipped with a central shaft 217. The central shaft 217 provides stable rotational support for the storage shaft 216. The outer surface of the storage shaft 216 is connected to one end of the hand restraint strap 204 and the leg restraint strap 206, respectively. When the storage shaft 216 rotates, the restraint straps can be wrapped around its outer surface, realizing the function of storing the restraint straps. Secondly, both the first restraint compartment 205 and the second restraint compartment 208 are equipped with an elastic plate 218. The outer surface of the elastic plate 218 is rotatably designed... There is a drive rod 219, which passes through the first restraint chamber 205 and the second restraint chamber 208 respectively through the limiting groove 220. When it is necessary to release the restraint straps, the medical staff pushes the drive rod 219. The movement of the drive rod 219 will cause the elastic plate 218 connected to it to deform. During the deformation of the elastic plate 218, a squeezing force will be generated on the hand restraint strap 204 and the leg restraint strap 206, so that the hand restraint strap 204 and the leg restraint strap 206 can be fixed. At this time, the medical staff can use the released restraint straps to restrain the patient's hands or lower limbs.

[0059] Meanwhile, the inner walls of the first restraint chamber 205 and the second restraint chamber 208 near the drive rod 219 are equipped with return springs. When the drive rod 219 is pushed, the return springs are compressed and store elastic potential energy. When the restraint straps are no longer needed, the medical staff release the drive rod 219, and the return springs return to their original state, releasing the elastic potential energy and driving the drive rod 219 back to its initial position. During the reset process of the drive rod 219, the elastic plate 218 also returns to its initial state, and at the same time, it drives the storage shaft 216 to rotate in the opposite direction under the force of the first torsion spring, so that the restraint straps are rewound onto the storage shaft 216, thereby realizing the automatic storage of the restraint straps.

[0060] like Figure 13 As shown, each drive rod 219 has a protrusion on its outer side, and the shape of the protrusion is adapted to the limiting groove 220. The limiting groove 220 limits the drive rod 219 through the protrusion. The transverse slots of the two limiting grooves 220 are connected to the interior of the first constraint chamber 205 and the second constraint chamber 208, respectively. The longitudinal slots of the two limiting grooves 220 are not connected to the interior of the first constraint chamber 205 and the second constraint chamber 208.

[0061] Specifically, the engagement between the protrusion on the outer side of the drive rod 219 and the limiting groove 220 plays a crucial role in controlling the storage and use of the restraint strap. Each drive rod 219 has a protrusion on its outer side, and the shape of the protrusion is adapted to the limiting groove 220. Its transverse slots are connected to the interiors of the first restraint chamber 205 and the second restraint chamber 208, respectively, while the longitudinal slots are not connected to the interiors of the first restraint chamber 205 and the second restraint chamber 208. When the drive rod 219 is in different states, the position of the protrusion in the limiting groove 220 will change, thereby realizing the limiting function of the drive rod 219. When the drive rod 219 is in the initial state, the protrusion on the outer side of the drive rod 219 is located in the horizontal direction. At this time, the protrusion can move freely in the transverse slot of the limiting groove 220, and the drive rod 219 is not restricted by the limiting groove 220. This means that medical staff can easily push or pull the drive rod 219 to realize the free storage or release operation of the restraint strap.

[0062] When the drive rod 219 is in the working state, medical staff push the drive rod 219 to a certain position, so that the protrusion is in the vertical direction. Since the longitudinal slot of the limiting groove 220 is not connected to the inside of the restraint chamber, the protrusion will be stuck by the limiting groove 220. At this time, the drive rod 219 is restricted by the limiting groove 220 and cannot move freely. In this way, the restraint belt will remain in the current released state and can stably restrain the patient. In actual use, it is necessary to ensure that the restraint belt remains stable in both the storage and use states. This solves the problem of instability of the restraint belt in the storage and use states and ensures the normal use and storage of the restraint belt.

[0063] When the drive rod 219 is in the initial state, the protrusion on the outer side of the drive rod 219 is in the horizontal direction, and the protrusion is in the limiting groove 220. The return spring is in the neutral state, and the drive rod 219 is not restricted by the limiting groove 220 at this time. The elastic plate 218 is in the initial state. When the drive rod 219 is in the working state, the protrusion on the outer side of the drive rod 219 is in the vertical direction, the return spring is in the compressed state, the drive rod 219 is restricted by the limiting groove 220 at this time, and the elastic plate 218 is in the deformed state.

[0064] Specifically, regarding the coordination of various components of the drive rod 219 in different states: When the drive rod 219 is in its initial state, the protrusion on the outer side of the drive rod 219 is in the horizontal direction. At this time, the protrusion and the limiting groove 220 are in a freely movable engagement state. The return spring is in a neutral state, that is, there is no stretching or compression. The elastic plate 218 is also in its initial state, without deformation. The storage shaft 216 can rotate freely. This allows the restraint strap to be easily stored or released. Medical staff can adjust the length and position of the restraint strap according to actual needs to prepare for patient restraint. Secondly, when it is necessary to restrain the patient, the medical staff pushes the drive rod 219, causing the protrusion to move in the vertical direction. During this process, the return spring is compressed, storing elastic potential energy. At the same time, the elastic plate 218 deforms, generating a certain force on the storage shaft 216, keeping the restraint strap in the released state. At this time, the drive rod 219 is restricted by the limiting groove 220 and cannot move freely, ensuring the stability of the restraint strap and effectively restraining the patient.

[0065] When restraint is no longer needed, medical staff release the drive rod 219, the return spring returns to its original state, driving the drive rod 219 back to its initial position. The protrusion returns to the horizontal direction, the elastic plate 218 also returns to its initial state, and the storage shaft 216 can rotate freely again. The restraint strap can be stored away. In psychiatric nursing, it is necessary to quickly adjust the restraint state according to the patient's actual situation. Through the coordination of the changes in the position of the protrusion, the state of the return spring, and the state of the elastic plate 218 in the initial and working states of the drive rod 219, the function of flexibly switching and stably maintaining the restraint strap storage and use states is achieved. This solves the problem of quickly adjusting the restraint state according to the patient's actual situation and ensuring stability, thus improving the efficiency and quality of psychiatric nursing work.

[0066] like Figure 11 As shown, both the first slider 211 and the second slider 212 are equipped with a scroll inside, and the outer surfaces of the multiple scrolls are respectively connected to one end of the first constraint band 214 and the second constraint band 215. The ends of the multiple scrolls are equipped with second torsion springs, which are used to reset the two scrolls respectively. The ends of the two first constraint bands 214 and the two second constraint bands 215 away from the scrolls are connected to each other by a pin.

[0067] Specifically, regarding the storage and restraint functions of the first restraint band 214 and the second restraint band 215, the internal components of the first slider 211 and the second slider 212 work together effectively. Both the first slider 211 and the second slider 212 have internal scrolls. The outer surfaces of multiple scrolls are connected to one end of the first restraint band 214 and the second restraint band 215, respectively. When medical personnel pull the first restraint band 214 and the second restraint band 215 from the scrolls to restrain the patient's upper limbs, the scrolls rotate as the restraint bands are stretched. Each end of the scroll is equipped with a second torsion spring. During the rotation of the scrolls, the second torsion springs twist, storing elastic potential energy. When the restraint bands are no longer needed, the second torsion springs return to their original state, releasing the elastic potential energy and causing the scrolls to rotate in the opposite direction. This reverse rotation rewinds the first restraint band 214 and the second restraint band 215 onto the scrolls, achieving automatic storage of the restraint bands. This automatic storage method not only facilitates the operation of medical personnel but also ensures the neatness and orderliness of the restraint bands, avoiding the chaos and damage caused by haphazard placement.

[0068] Two first restraint straps 214 and two second restraint straps 215 are connected to each other at the ends away from the reel via pins. When it is necessary to restrain the patient's upper limb, medical staff pull out the first restraint straps 214 and the second restraint straps 215 from the reel, wrap them around the patient's upper limb, and then insert the pins into the corresponding holes to firmly connect the two restraint straps together, forming a stable restraint structure. The pin connection method is both strong and easy to operate. Medical staff can flexibly adjust the insertion position of the pins according to the thickness of the patient's upper limb and the tightness of the restraint, ensuring both the restraint effect and the patient's comfort. In actual nursing care, the storage and organization of restraint straps and the stability of restraint are very important. Through the cooperation of the reel, the second torsion spring, and the pins, the functions of convenient storage and firm restraint of restraint straps are achieved, thereby solving the problems of restraint strap storage and organization and stable restraint, and ensuring the normal use and management of restraint straps.

[0069] like Figure 4 As shown, a base plate 209 is provided above the load-bearing frame 301, and a cushion 201 is provided on the surface of the base plate 209. A connecting rod 210 is fixedly provided on one side of the base plate 209, and a force-bearing ring 202 is provided at the end of the connecting rod 210 away from the base plate 209. A handrail 308 is provided on the inner diameter of the force-bearing ring 202. A pad 311 is provided on the outer surface of the handrail 308, and the bottom end of the handrail 308 is located on one side of the load-bearing frame 301. A limiting plate 203 is provided on the outer surface of the handrail 308 away from the load-bearing frame 301, and a compression spring is provided between the limiting plate 203 and the force-bearing ring 202. A pressure sensor is provided on the side of the limiting plate 203 facing the compression spring. A hinge 309 is provided on one side of the load-bearing frame 301, and a limiting piece 310 is hinged inside the hinge 309.

[0070] Specifically, in providing a comfortable sitting posture for psychiatric patients and monitoring their condition, the support frame 301 and related components work together. The support frame 301 has a base plate 209 on top, which provides a stable sitting platform for the patient. The surface of the base plate 209 is covered with a cushion 201, which is made of soft and comfortable material. This cushion can effectively buffer the pressure between the patient's body and the base plate 209, increasing the patient's comfort when sitting. In addition, a connecting rod 210 is fixedly installed on one side of the base plate 209. The connecting rod 210 serves to connect the base plate 209 and the force ring 202. The end of the connecting rod 210 away from the base plate 209 is provided with a force ring 202. The inner diameter of the force ring 202 is provided with a handrail 308. The handrail 308 provides hand support for the patient, making it easier for the patient to maintain body balance when sitting. The outer surface of the handrail 308 is provided with a pad 311. The pad 311 is made of soft and non-slip material, which not only increases the comfort of the patient when holding the handrail 308, but also prevents the patient's hand from slipping due to sweating or other reasons.

[0071] The bottom end of the handrail 308 is located on one side of the load-bearing frame 301, ensuring the stability of the handrail 308. A limiting plate 203 is provided on the outer surface of the handrail 308 away from the load-bearing frame 301. A compression spring is provided between the limiting plate 203 and the force ring 202. A pressure sensor is provided on the side of the limiting plate 203 facing the compression spring. When the patient sits, he may unconsciously apply pressure to the handrail 308. At this time, the handrail 308 will transmit the pressure to the limiting plate 203, and the limiting plate 203 will compress the compression spring.

[0072] Because neurological patients typically experience unpredictable and irregular seizures, leading to sudden generalized convulsions or agitation, failure to restrain them promptly can result in the restraints coming loose and medical staff being unable to arrive in time to subdue them. Therefore, this plan includes the following adjustments:

[0073] When the patient is in a normal state, their body is always in contact with the cushion 201, which keeps the compression value of the compression spring within a fixed range of small changes (since the patient is in a non-symptom state). When the compression spring is detected by a pressure sensor, if the compression spring changes frequently and the change threshold exceeds the set change range, it indicates that the patient is in a symptom state and needs to be forcibly restrained. First, the first electric actuator 213 in area A (the left side of the connecting frame 103) drives the first slider 211 in area A to slide along the outer surface of the slide bar 105. Then, the second electric actuator in area B (the right side of the connecting frame 103) cooperates with the slide bar 105, causing the second slider 212 in area B to slide in the opposite direction to the sliding of the first slider 211 in area A. At this time, the first restraint strap 214 and the second restraint strap 215 are intersecting, thereby reducing the patient's activity space when they are symptom-affected and preventing the first restraint strap 214 or the second restraint strap 215 from detaching from the patient due to vigorous activity and causing injury to medical staff or other personnel.

[0074] It should be noted that the return spring is a standard commonly used in bed chairs on the market, which can withstand high pressure and is not prone to spring fatigue. At the same time, there are at least two pressure sensors, which are set on the left and right sides of the seat cushion 201 respectively, and the return springs on both sides of the bottom of the seat cushion 201 are monitored in real time to avoid inaccurate detection data due to the patient's lying habits.

[0075] In addition, a hinge 309 is provided on one side of the load-bearing frame 301, and a limiting piece 310 is hinged inside the hinge 309. The limiting piece 310 can limit and protect the relevant components. At the same time, the limiting piece 310 can also buffer the impact of external forces on other components to a certain extent, and extend the service life of the components.
