Abstract
Description
Technical Field
[0001] This invention relates to the field of mental health technology, and in particular to a self-harm prevention safety structure for use in mental health departments. Background Technology
[0002] In clinical diagnosis and nursing care in mental health departments, patients with mental illnesses such as depression, schizophrenia, borderline personality disorder, and bipolar disorder are a high-risk group for self-harm. These patients often engage in non-suicidal self-harm or suicidal tendencies due to emotional instability, inability to effectively release psychological stress, or being dominated by mental symptoms such as hallucinations and delusions. Common self-harm methods include cutting, biting, hitting the head, swallowing foreign objects, and burning. Some patients may also scratch themselves or interfere with wound healing. Currently, clinical prevention of self-harm for such patients mainly relies on simple restraint devices such as restraint belts and restraint clothing. As a commonly used protective restraint method in psychiatry, the core function of these devices is to reduce the probability of self-harm by restricting the patient's limb movement.
[0003] However, traditional restraint devices are mostly rigid restraints, which can easily lead to poor blood circulation and muscle stiffness in the patient's limbs during restraint. Long-term use may also aggravate the patient's resistance and even induce more intense agitation and self-harming behavior. Furthermore, they cannot specifically prevent specific self-harming behaviors such as biting the tongue or head impact, and the protection is not targeted or comprehensive enough to avoid the risk of self-harm by the patient.
[0004] In view of this, we will study and improve upon the existing problems to provide a self-harm prevention safety structure for mental health departments. The aim is to solve the problems and improve the practical value through this technology. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a self-harm prevention safety structure for use in mental health departments.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a self-harm prevention safety structure for use in mental health departments, including a seat, with a cushion portion above the seat and a support portion on the surface of the cushion portion; The anti-self-harm mechanism includes an electric push rod fixedly installed on the back of the seat cushion. The output end of the electric push rod is connected to a transmission component that moves along the inside of the guide groove. One end of the transmission component is fixedly connected to a clamping part. A guide rail is fixedly connected to one side of the clamping part. A guide block slides inside the guide rail. A fixing component is rotatably provided on one side of the guide block. A pressure bearing component is fixed on the surface of the fixing component. A locking component is provided above the guide block. A gripping mechanism includes a mounting housing that is fixedly installed through the surface of a support portion. Two sets of symmetrical movable plates slide inside the mounting housing. A gripping member is fixedly connected between the two sets of movable plates. A guide channel is provided inside the mounting housing. The gripping member slides along the guide channel. An elastic element B is fixedly connected between the movable plates and the mounting housing. Multiple air cushions are provided on the outer wall of the gripping member. The gripping member has a hollow structure. An air supply component for supplying air to the inside of the gripping member is provided on the back of the seat portion. The soothing mechanism includes an arc-shaped plate that slides inside a pressure-bearing component, with multiple massage sticks mounted on the top of the arc-shaped plate, and the soothing mechanism is connected to an inflation assembly.
[0007] Preferably, a protective contact layer is provided on one side of the clamping part, and the fixing member is made of an elastic material.
[0008] Preferably, the locking assembly includes a locking block fixed to the guide block, the surface of the locking block having multiple sets of equally spaced insertion interfaces, a locking rod that slides on one side of the guide rail and engages with the locking block, and an elastic element A is fixedly connected between the guide block and the locking rod.
[0009] Preferably, the inflatable component includes an air storage tube fixed to the back of the seat cushion, the outer wall of the air storage tube is integrally formed with a guide tube, the guide tube is internally threaded with an adjusting rod, and a connecting tube connects the air storage tube to the grip.
[0010] Preferably, the outer wall of the gas storage pipe is connected to a connecting pipe A, the bottom end of the pressure bearing component is connected to a connecting pipe B, a magnetic ring is installed at one end of both connecting pipe A and connecting pipe B, connecting pipe A and connecting pipe B are inserted into each other, and a regulating valve is installed on the outer wall of connecting pipe A.
[0011] Preferably, an upper arm ring is installed on the surface of the support portion, and two sets of symmetrical fixing rings are installed on the front of the seat.
[0012] Preferably, the guide rail has an arc-shaped groove on its side, and a connecting block is fixed to one end of the fixing member, the connecting block sliding along the inside of the arc-shaped groove.
[0013] Preferably, the pressure-bearing component has an elastic element C inside, a sponge strip is bonded to the surface of the pressure-bearing component, one end of the elastic element C is fixed to the bottom end of the arc-shaped plate, and the other end of the elastic element C is fixed to the inner wall of the pressure-bearing component.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention activates two sets of electric push rods fixed to the back of the seat cushion. The output end of the electric push rod drives the transmission component to slide directionally along the interior of a preset guide groove, thereby causing the two sets of clamping parts at one end of the transmission component to move synchronously toward the patient's head. According to the specific size and shape of the patient's head and face, the two sets of clamping parts can adaptively close together, thereby forming a stable clamp on both sides of the patient's head, effectively limiting the arbitrary deflection of the head during treatment and preventing the patient from being bumped or injured. After the head is clamped in place, the staff can further pull the fixing component connected to the guide block to flexibly adjust its position along the guide rail, so that the pressure-bearing component on the surface of the fixing component precisely presses against the patient's chin. By flexibly closing and limiting the chin area, the possibility of the patient biting their tongue or engaging in self-harming behavior under stress or sudden emotional state is prevented, thus improving the safety of the treatment environment and the treatment effect.
[0015] 2. After the patient's upper arm is initially restrained by fixing it to the upper arm ring, the present invention guides the patient to grasp the gripping mechanism. The operator rotates the adjusting rod, which moves it upward along the guide tube and compresses the gas. The gas is supplied to the hollow gripping component through the connecting tube, causing the outer wall air cushion to inflate and form a flexible buffer layer. This can prevent the patient from self-harming by grasping when emotionally agitated, improve gripping comfort, and reduce hand muscle stiffness. At the same time, the moving plates at both ends of the gripping component elastically cooperate with the elastic element B, allowing the patient to slide slightly when grasping. The elastic feedback releases hand tension, relieves limb agitation, and helps the patient calm down.
[0016] 3. In this invention, when the patient presses the air cushion on the outer wall of the gripping component with their fingers, the pressing action compresses the gas inside the gripping component, causing periodic changes in the air pressure inside the gripping component. This change is then transmitted to the interior of the pressure-bearing component. As the air pressure inside the pressure-bearing component rises and falls periodically, the air pressure pushes the arc-shaped plate that is slidably connected inside the component and the multiple massage sticks installed at the top of the arc-shaped plate upwards. This allows the massage sticks to precisely contact the sponge strip that is attached to the patient's head. Through the soft cushioning effect of the sponge strip, a gentle and even reciprocating massage is performed on the patient's head, thereby relieving muscle tension in the head, soothing the nerves, improving head discomfort caused by long-term emotional agitation, further assisting the patient in calming their emotions, helping the patient maintain a stable state, and improving the treatment effect.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0020] See Figures 1 to 10 As shown, the present invention provides a self-harm prevention safety structure for use in mental health departments, including a seat 1, a cushion 2 on the upper part of the seat 1, and a support 3 on the surface of the cushion 2; The anti-self-harm mechanism includes an electric push rod 41 fixedly installed on the back of the seat cushion 2. The output end of the electric push rod 41 is connected to a transmission component 43 that moves along the inside of the guide groove 42. One end of the transmission component 43 is fixedly connected to a clamping part 44. A guide rail 45 is fixedly connected to one side of the clamping part 44. A guide block 46 slides inside the guide rail 45. A fixing component 47 is rotatably provided on one side of the guide block 46. A pressure bearing component 410 is fixed on the surface of the fixing component 47. A locking component is provided above the guide block 46. It should be noted that in actual use, the patient first sits on the seat cushion 2 of the seat 1. The staff first puts the patient's upper arm into the upper arm ring 7 installed on the surface of the support 3, and fixes the patient's legs inside the two sets of symmetrical fixing rings 8 installed on the front of the seat 1. In this way, the patient's limbs are initially fixed, which effectively reduces the patient's arm and leg mobility and initially improves the treatment effect. After initial positioning is completed, two sets of electric push rods 41 fixed to the back of the seat cushion 2 are simultaneously activated. The output end of the electric push rod 41 drives the transmission component 43 to slide directionally along the preset guide groove 42, thereby driving the two sets of clamping parts 44 at one end of the transmission component 43 to move synchronously toward the patient's head. According to the specific size and shape of the patient's head and face, the two sets of clamping parts 44 can adaptively move closer together, thereby forming a stable clamp on both sides of the patient's head, effectively limiting the random deflection of the head during treatment, and preventing the patient from being bumped or injured. Once in place, staff can further pull the fixing part 47, which is rotatably connected to the guide block 46, and flexibly adjust its position along the guide rail 45. When adjusted to the position to be fixed, the locking rod 49 is inserted into the insertion interface on the surface of the locking block 48 to lock the fixing part 47. This allows the pressure-bearing part 410 on the surface of the fixing part 47 to precisely press against the patient's jaw. By flexibly closing and limiting the jaw area, the possibility of the patient biting their tongue or engaging in other self-harming behaviors under stress or sudden emotional states is prevented, thus improving the safety of the treatment environment and the treatment effect.
[0021] The gripping mechanism includes a mounting housing 52 that is fixedly installed through the surface of the support part 3. Two sets of symmetrical movable plates 53 slide inside the mounting housing 52. A gripping member 54 is fixed between the two sets of movable plates 53. A guide channel is opened inside the mounting housing 52. The gripping member 54 slides along the guide channel. An elastic member B55 is fixed between the movable plate 53 and the mounting housing 52. Multiple air cushions 56 are provided on the outer wall of the gripping member 54. The gripping member 54 has a hollow structure. An air supply component for supplying air to the inside of the gripping member 54 is provided on the back of the seat part 2. It should be noted that after the staff fixes the patient's upper arm inside the upper arm ring 7 on the surface of the support part 3 and completes the initial restraint of the patient's upper limb, it is necessary to guide the patient's hand to naturally grasp the gripper 54 of the grasping mechanism to ensure that the patient's hand has a stable gripping carrier. Subsequently, the staff manually rotates the adjusting rod 59. Rotating the adjusting rod 59 can make it move upward along the inside of the guide tube 58. During the movement, the adjusting rod 59 will continuously squeeze the gas inside the guide tube 58 and the gas storage tube 57, so that the gas inside the gas storage tube 57 generates a certain pressure. Then, through the connecting pipe 510 connecting the gas storage tube 57 and the gripper 54, a stable gas supply is supplied to the hollow structure of the gripper 54. After the gas enters the inside of the gripper 54, it will cause the multiple sets of air cushions 56 on the outer wall of the gripper 54 to be pressed. As the gripper gradually inflates and expands, it forms a flexible buffer layer. At this point, the patient can stably grasp the inflated gripper 54. This effectively prevents the patient from engaging in self-harm behaviors such as scratching or gripping their hands due to emotional agitation. Furthermore, the flexible air cushion 56 provides support and improves the patient's hand grip comfort, reducing hand muscle stiffness caused by tension and agitation. Simultaneously, the gripper 54, through the movable plates 53 fixed at both ends, forms an elastic engagement with the elastic element B55. When the patient grasps the gripper 54, the gripper 54 can drive the movable plates 53 to slide slightly along the pre-set guide channel inside the mounting housing 52. During the sliding process, the elastic element B55 will generate corresponding elastic feedback, further assisting the patient in releasing hand tension, relieving limb agitation, and helping the patient gradually calm down. In addition, once the patient's mood improves and limb agitation is effectively controlled, under the professional guidance of staff, the patient can hold the grip piece 54 and swing it from side to side, while pressing the air cushion 56 on the outer wall of the grip piece 54 with their fingers. This can effectively relieve muscle tension and fatigue in the patient's hands, relax the hand muscles, and allow for flexible movement of the hand joints, promote blood circulation in the hands, prevent muscle atrophy in the hands caused by long-term limb restraint, and improve hand and limb function.
[0022] The soothing mechanism includes an arc-shaped plate 61 that slides inside the pressure-bearing component 410. Multiple massage sticks 62 are mounted on the top of the arc-shaped plate 61. The soothing mechanism is connected to the inflation component.
[0023] It should be noted that after the patient's mood improves, the staff flips the fixing piece 47 upwards and attaches it to the patient's head. The staff then connects the connecting pipe A64 to the connecting pipe B65 via the magnetic ring 66 in a sealed manner. Subsequently, the staff adjusts the regulating valve 67 from the closed state to the open state, creating a communication channel between the gas storage pipe 57 and the pressure-bearing component 410. At this time, when the patient, under the professional guidance of the staff, repeatedly presses the air cushion 56 on the outer wall of the grip 54 with their fingers, the pressing action will compress the gas inside the grip 54, causing the air pressure inside the grip 54 to change periodically. This air pressure change will be transmitted in reverse through the connecting pipe 510 to the storage pipe. Inside the trachea 57, the air pressure is transmitted to the pressure-bearing component 410 via the open regulating valve 67, connecting pipe A64, and connecting pipe B65. As the internal air pressure of the pressure-bearing component 410 rises and falls periodically, the air pressure pushes the arc-shaped plate 61 and the multiple massage sticks 62 mounted on the top of the arc-shaped plate 61 upwards. This allows the massage sticks 62 to precisely contact the sponge strip 68 that is attached to the patient's head. Through the soft cushioning effect of the sponge strip 68, a gentle and even reciprocating massage is performed on the patient's head, thereby relieving muscle tension in the head, soothing nerves, improving head discomfort caused by long-term emotional agitation, further assisting the patient in calming down, helping the patient maintain a stable state, and improving the treatment effect.
[0024] In an optional embodiment, a protective contact layer is provided on one side of the clamping part 44, and the fastener 47 is made of an elastic material. The protective contact layer can prevent secondary injuries such as abrasions and strangulations to the patient's skin during the restraint process.
[0025] In an optional embodiment, the locking assembly includes a locking block 48 fixedly attached to the guide block 46. The surface of the locking block 48 has multiple sets of equally spaced insertion interfaces. A locking rod 49 that is slidably attached to one side of the guide rail 45 and engages with the locking block 48 is inserted into it. An elastic element A411 is fixedly connected between the guide block 46 and the locking rod 49.
[0026] In an optional embodiment, the inflation assembly includes an air storage tube 57 fixed to the back of the seat cushion 2, an integrally formed guide tube 58 on the outer wall of the air storage tube 57, an adjustment rod 59 threadedly connected to the inside of the guide tube 58, and a connecting tube 510 communicating between the air storage tube 57 and the grip 54.
[0027] In an optional embodiment, the outer wall of the gas storage pipe 57 is connected to a connecting pipe A64, and the top end of the pressure bearing member 410 is connected to a connecting pipe B65. A magnetic ring 66 is installed at one end of both the connecting pipe A64 and the connecting pipe B65. The connecting pipe A64 and the connecting pipe B65 are plugged into each other, and a regulating valve 67 is installed on the outer wall of the connecting pipe A64.
[0028] In an optional embodiment, an upper arm ring 7 is mounted on the surface of the support 3, and two sets of symmetrical fixing rings 8 are mounted on the front of the seat 1.
[0029] In an optional embodiment, an arc-shaped groove 9 is provided on the side of the guide rail 45, and a connecting block is fixed to one end of the fixing member 47. The connecting block slides along the inside of the arc-shaped groove 9, and the arc-shaped groove 9 can guide the fixing member 47 to rotate smoothly along the arc-shaped trajectory.
[0030] In an optional embodiment, the pressure-bearing member 410 has an elastic member C63 inside, and a sponge strip 68 is bonded to the surface of the pressure-bearing member 410. One end of the elastic member C63 is fixed to the bottom end of the arc plate 61, and the other end of the elastic member C63 is fixed to the inner wall of the pressure-bearing member 410.
[0031] Working principle: In actual use, the patient first sits on the seat cushion 2 of the seat 1. The staff first puts the patient's upper arm into the upper arm ring 7 installed on the surface of the support 3, and fixes the patient's legs inside the two sets of symmetrical fixing rings 8 installed on the front of the seat 1. In this way, the patient's limbs are initially fixed, which effectively reduces the patient's arm and leg mobility and initially improves the treatment effect. After the initial positioning is completed, the two sets of electric push rods 41 fixed to the back of the seat cushion 2 are activated simultaneously. The output end of the electric push rod 41 drives the transmission component 43 to slide in the direction of the preset guide groove 42, thereby driving the two sets of clamping parts 44 at one end of the transmission component 43 to move synchronously toward the patient's head. After the head is clamped in place, the staff can further pull the fixing part 47 that is rotatably connected to the guide block 46 and flexibly adjust the position along the guide rail 45. When it is adjusted to the position to be fixed, the locking rod 49 is inserted into the insertion interface on the surface of the locking block 48 to lock the fixing part 47, so that the pressure bearing part 410 on the surface of the fixing part 47 is precisely pressed against the patient's chin, and the chin is flexibly closed and limited. After the staff fixes the patient's upper arm inside the upper arm ring 7 on the surface of the support part 3 and completes the initial restraint of the patient's upper limb, it is necessary to guide the patient's hand to naturally grasp the gripper 54 of the grasping mechanism to ensure that the patient's hand has a stable gripping carrier. Then, the staff manually rotates the adjusting rod 59. Rotating the adjusting rod 59 can make it move upward along the inside of the guide tube 58. During the movement, the adjusting rod 59 will continuously compress the gas inside the guide tube 58 and the gas storage tube 57, so that the gas inside the gas storage tube 57 generates a certain pressure, and then through the connecting tube 510 connecting the gas storage tube 57 and the gripper 54, it is released into the hollow space. The gripper 54 of the structure is stably supplied with air. After the air enters the gripper 54, it will cause the multiple air cushions 56 on the outer wall of the gripper 54 to gradually fill and expand, forming a flexible buffer layer. At the same time, the gripper 54 forms an elastic fit with the elastic element B55 through the movable plate 53 fixed at both ends. When the patient grasps the gripper 54, the gripper 54 can drive the movable plate 53 to slide slightly along the pre-set guide channel inside the mounting housing 52. During the sliding process, the elastic element B55 will generate corresponding elastic feedback, further assisting the patient to release hand tension, relieve limb agitation, and help the patient gradually calm down. In addition, once the patient's mood improves and limb agitation is effectively controlled, under the professional guidance and instruction of the staff, the patient can hold the grip 54 and swing it from side to side, while pressing the air cushion 56 on the outer wall of the grip 54 with their fingers. This can effectively relieve muscle tension and fatigue in the patient's hands, relax the hand muscles, and allow for flexible movement of the hand joints, promote blood circulation in the hands, prevent muscle atrophy in the hands caused by long-term limb restraint, and improve hand and limb function. After the patient's mood improves, the staff flips the fixing piece 47 upwards and attaches it to the patient's head. The staff then connects the connecting pipe A64 to the connecting pipe B65 via the magnetic ring 66 in a sealed manner. Next, the staff adjusts the regulating valve 67 from the closed state to the open state, creating a communication channel between the gas storage pipe 57 and the pressure-bearing component 410. At this point, under the professional guidance of the staff, when the patient repeatedly presses the air cushion 56 on the outer wall of the grip 54 with their fingers, the pressing action compresses the gas inside the grip 54, causing the grip 54 to... The internal air pressure changes periodically, and this change is transmitted in the reverse direction to the air storage pipe 57 through the connecting pipe 510. Then, through the open regulating valve 67, connecting pipe A64 and connecting pipe B65, it is transmitted to the inside of the pressure bearing component 410. As the internal air pressure of the pressure bearing component 410 rises and falls periodically, the air pressure pushes the arc plate 61 that is slidably connected inside and the multiple sets of massage sticks 62 installed on the top of the arc plate 61 to move upward. This allows the massage sticks 62 to accurately contact the sponge strip 68 that is attached to the patient's head. Through the flexible cushioning effect of the sponge strip 68, a gentle and even reciprocating massage is performed on the patient's head.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
