Description
A limb restraint device for mental health treatment Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a limb restraint device for mental health treatment. Background Technology
[0002] Mental illness is a type of psychological disorder. Psychological disorders refer to various abnormal psychological processes, abnormal personality traits, and abnormal behavioral patterns caused by physiological, psychological, or social reasons. It manifests as an inability to act in a socially acceptable manner, resulting in consequences that are maladaptive to both the individual and society. Some patients with mental illness often fail to cooperate during treatment, which affects their treatment. In severe cases, patients may engage in self-harm, harm others, or damage medical equipment, threatening their own safety and that of medical staff, and disrupting the treatment process. To meet medical needs, restrictive measures may be taken for such patients.
[0003] However, existing restraint devices mostly use mechanical restraint structures with fixed force. The tightness of the restraint is difficult to flexibly adapt and dynamically adjust according to the patient's condition. Either the restraint is too tight, which can cause excessive pressure on the patient's muscles and blood vessels, leading to poor blood circulation and complications such as skin abrasions, pressure sores, and nerve damage, or even serious consequences such as limb necrosis, increasing the patient's discomfort and risk of limb injury; or the restraint is too loose, which cannot effectively restrict the patient's limb movement. The patient is likely to break free of the restraint due to agitation, which may lead to dangerous situations such as self-harm, harming others, or damaging medical equipment, thus failing to achieve a reliable restraint and protection effect.
[0004] In view of this, this paper studies and improves upon existing problems, and provides a limb restraint device for mental health treatment, aiming to solve the problem and improve its practical value through this technology. Summary of the Invention

Guide cylinders are fixedly connected to both sides of the threaded cylinder through brackets. A transmission rod is slidably provided inside the guide cylinder. The bottom end of the transmission rod is fixedly connected to the pressing member. A power mechanism that drives the transmission rod to slide by the arc-shaped limiting member is provided on one side of the guide plate. A spraying mechanism is provided, which includes a spraying pipe connected to the power mechanism through a connecting pipe. Multiple sets of spraying elements for spraying sedatives are provided on the outer wall of the spraying pipe.
[0007] Preferably, the fixing component includes an adjusting screw threaded to the bottom end of the clamping plate, a clamping member fixed to the top end of the adjusting screw, a guide groove being provided in the clamping plate, and the clamping member being slidably disposed along the guide groove.
[0008] Preferably, the surface of the placement plate is provided with a buffer pad layer, and the bottom end of the arc-shaped limiting member is provided with multiple sets of buffer airbags. Both the buffer pad layer and the buffer airbags are made of medical-grade flexible material.
[0009] Preferably, the limiting guide is provided with a rolling component on the side near the guide plate, the rolling component rolls and fits against the side wall of the guide plate, and the rolling component is evenly distributed along the length direction of the limiting guide.
[0010] Preferably, the power mechanism includes a sleeve fixed to the surface of the guide plate, a lead screw rotatably disposed inside the sleeve, a magnetic block fixed to the outer wall of the lead screw, a piston threaded to the outer wall of the lead screw, a magnetic ring sleeved on the outer wall of the sleeve that magnetically engages with the magnetic block, a toothed ring fixed to the outer wall of the magnetic ring, a rack meshing with the toothed ring fixed to one end of the limiting guide, and the sleeve and the guide cylinder being connected by an air supply pipe.
[0011] Preferably, the sleeve is provided with an axial limiting member, and the piston is slidably arranged along the axial limiting member.
[0012] Preferably, the locking assembly includes a locking member fixed to one end of the fixing ring, a socket is provided on one side of the placement plate, a pin is slidably disposed in the socket, an operating plate is fixed to one end of the pin, a spring B is sleeved on the outer wall of the pin, and the two ends of the spring B are fixed to the side wall of the placement plate and the side wall of the operating plate, respectively, and the pin and the locking member are inserted into each other.
[0013] Preferably, a liquid storage tank is fixedly connected to the outer wall of the fixed ring, and the liquid storage tank is connected to the guide cylinder through a liquid suction pipe. Both the liquid suction pipe and the connecting pipe are provided with unidirectional guide components.
[0014] Preferably, the spray pipe has an arc-shaped structure that fits the fixing ring, the spray element is inclined upward, and the spacing between adjacent sets of spray elements is consistent.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses the rotating adjusting component, and the up and down movement of the adjusting component will drive the telescopic rod to rise and fall synchronously, thereby changing the initial compression degree of the spring A sleeved on the outer wall of the telescopic rod, so as to adapt to the needs of different patients' conditions. When the patient's upper arm is inside the arc-shaped limiting component, the spring A is always in a compressed state, tightly abutting the arc-shaped limiting component against the surface of the patient's upper arm, thereby achieving the constraint of the patient's upper arm movement. At the same time, the constraint method of using the spring A in conjunction with the arc-shaped limiting component allows the patient's upper arm to retain a small space for movement under the premise of being effectively constrained, avoiding excessive pressure and compression of the patient's upper arm muscles and blood vessels by the arc-shaped limiting component, ensuring smooth blood circulation of the patient's limbs, and reducing the patient's discomfort and risk of limb injury during the constraint process.
[0016] 2. This invention achieves adaptive locking of the patient's agitated limbs by moving the arc-shaped limiting component upwards when the patient exhibits agitation. This movement of the piston component compresses the gas inside the sleeve. The compressed high-pressure gas is then transported to the guide cylinder through the gas delivery pipe. The increased gas pressure exerts a downward thrust on the transmission rod inside the guide cylinder, causing it to move vertically downwards. This downward movement of the transmission rod causes the clamping component to move downwards synchronously, continuously compressing the spring A. As the compression of spring A increases, its elastic restoring force also strengthens. This elastic restoring force acts in the opposite direction on the arc-shaped limiting component, simultaneously increasing the clamping restraint force of the arc-shaped limiting component on the patient's upper arm. This achieves adaptive locking of the patient's agitated limbs, effectively preventing dangerous situations such as the patient breaking free of the restraint device due to agitation, causing self-harm, harming others, or damaging medical equipment.
[0017] 3. During the downward movement of the transmission rod, the sedative stored inside the guide cylinder is squeezed. The squeezed sedative is then transported to the spray pipe through the connecting pipe, and then precisely and quantitatively sprayed onto the vicinity of the patient's nasal cavity through the evenly distributed spray nozzles on the outer wall of the spray pipe. This allows for the automatic spraying of a quantitative sedative when the patient becomes agitated, quickly relieving the patient's agitation symptoms and stabilizing the patient's condition.

[0020] 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.
[0021] Referring to Figures 1 to 6, the present invention provides a limb restraint device for mental health treatment, comprising: a clamping plate 1; a supporting component, the supporting component including the clamping plate 1 and a placement plate 2 fixed to the top of the clamping plate 1, a fixing ring 3 for restraining limbs hinged on the placement plate 2, and a fixing component for fixing the device to the mounting surface at the bottom end of the clamping plate 1; a locking component, the locking component being disposed on one side of the placement plate 2 for detachable locking of the fixing ring 3 and the placement plate 2; and a limiting mechanism, the limiting mechanism including a threaded cylinder 41 integrally formed with the fixing ring 3, an adjusting member 42 being internally threaded to the threaded cylinder 41, and a telescopic member rotatably connected to the bottom end of the adjusting member 42 via a bearing. The telescopic rod 43 has an arc-shaped limiting member 45 fixed to its bottom end for conforming to the limb. A spring A44 is sleeved on the outer wall of the telescopic rod 43. A guide plate 46 is fixed inside the fixing ring 3. A limiting guide member 47 that slides along the guide plate 46 is fixed to the side wall of the arc-shaped limiting member 45. It should be noted that the patient first places his upper arm on the air cushion on the surface of the placement plate 2. Then, the staff rotates the fixing ring 3 to limit the upper arm that needs to be restrained inside the arc-shaped limiting member 45. Next, the operating plate 9 is pulled, causing the operating plate 9 to drive the pin 10 to slide and insert into the locking member 11 at one end of the fixing ring 3, thereby completing the locking of the fixing ring 3 and realizing the installation. After initial fixation of the device on the patient's upper arm, once the device is installed, staff can adjust the initial constraint force of the device using the adjusting component 42 according to the patient's specific condition. Specifically, rotating the adjusting component 42 causes it to move up and down along the vertical direction of the threaded cylinder 41, which is integrally formed with the fixed ring 3. This up-and-down movement of the adjusting component 42 synchronously raises and lowers the telescopic rod 43 connected to the bottom end via a bearing, thereby changing the initial compression degree of the spring A44 sleeved on the outer wall of the telescopic rod 43. The initial compression force of the spring A44 directly determines the constraint force of the arc-shaped limiting component 45 on the patient. The initial restraint force of the upper arm is designed to adapt to the needs of different patients. When the patient's upper arm is inside the arc-shaped limiting member 45, the spring A44 is always in a compressed state, tightly pressing the arc-shaped limiting member 45 against the surface of the patient's upper arm, thereby restraining the movement of the patient's upper arm. At the same time, the restraint method of using the spring A44 in conjunction with the arc-shaped limiting member 45 ensures that the patient's upper arm still retains a small space for movement while being effectively restrained, avoiding excessive pressure and compression of the muscles and blood vessels of the patient's upper arm by the arc-shaped limiting member 45, ensuring smooth blood circulation in the patient's limb, and reducing the patient's discomfort and risk of limb injury during the restraint process.
[0022] The clamping mechanism includes a clamping member 51 sleeved on the telescopic end of the telescopic rod 43. Guide cylinders 59 are fixed to both sides of the threaded cylinder 41 via brackets. A transmission rod 510 slides inside the guide cylinder 59, with its bottom end fixed to the clamping member 51. A power mechanism is provided on one side of the guide plate 46, driven by an arc-shaped limiting member 45 to slide the transmission rod 510. It should be noted that when the patient exhibits agitation, their upper arm will move within the small space reserved by the device's limiting mechanism. This movement directly acts on the arc-shaped limiting member 45, causing it to move upwards. As the arc-shaped limiting member 45 moves upwards, it simultaneously drives the limiting guide member 47... The rack 57, fixed to one end of the limiting guide 47, moves synchronously with the movement of the limiting guide 47. Since the rack 57 and the toothed ring 56 are meshed, the linear movement of the rack 57 is converted into the rotational motion of the toothed ring 56. When the toothed ring 56 rotates, it drives the magnetic ring 55 to rotate synchronously. The rotational torque of the magnetic ring 55 is transmitted to the magnetic block 54 through magnetic force, causing the magnetic block 54 to rotate synchronously. This, in turn, drives the lead screw 53 inside the sleeve 52 to rotate. During the rotation of the lead screw 53, the piston 58, guided by the limiting rod inside the sleeve 52, moves along the axial direction of the lead screw 53 towards both ends of the sleeve 52. The movement of the plug 58 compresses the gas inside the sleeve 52, increasing its pressure. The compressed high-pressure gas is then transported to the guide cylinder 59 via the gas delivery pipe 511. As gas continues to enter, the gas pressure inside the guide cylinder 59 gradually increases. This increased pressure exerts a downward thrust on the transmission rod 510 inside the guide cylinder 59. The transmission rod 510 moves vertically downwards along the inside of the guide cylinder 59. As the transmission rod 510 moves downwards, it causes the clamping member 51 to move downwards synchronously. During this downward movement, the clamping member 51 exerts a continuous compressive force on the spring A44, causing it to be rapidly compressed. As the compression of spring A44 increases, its elastic restoring force also increases. This elastic restoring force acts in the opposite direction on the arc-shaped limiting member 45, simultaneously increasing the clamping and restraining force of the arc-shaped limiting member 45 on the patient's upper arm. This achieves adaptive locking of the patient's restless limb, effectively preventing dangerous situations such as the patient breaking free of the restraint device due to restlessness, causing self-harm, harming others, or damaging medical equipment. At the same time, the airbag at the bottom of the arc-shaped limiting member 45 cooperates with the air cushion on the surface of the placement plate 2 to enhance the restraint stability while effectively buffering the restraint force, avoiding pressure damage to the patient's upper arm skin, and ensuring the comfort and safety of the patient's limb.
[0023] The spraying mechanism includes a spray pipe 62 connected to a power mechanism via a connecting pipe 65, and the outer wall of the spray pipe 62 is provided with multiple sets of spraying elements 63 for spraying sedatives.
[0024] It should be noted that when the transmission rod 510 moves downward, it will compress the sedative stored inside the guide cylinder 59. The compressed sedative will be transported to the spray pipe 62 through the connecting pipe 65, and then precisely and quantitatively sprayed onto the vicinity of the patient's nasal cavity through the evenly distributed spray nozzles 63 on the outer wall of the spray pipe 62. When the patient's agitation subsides and the upper arm movement weakens, the elastic restoring force of the spring A44 will push the arc-shaped limiting member 45 to return to its original position. This, in turn, will drive the magnetic ring 55 through the limiting guide member 47, rack 57, toothed ring 56, and other structures. The magnetic block 54 and the lead screw 53 rotate in opposite directions, causing the piston 58 to return to the center of the sleeve 52. The air pressure inside the guide cylinder 59 decreases, and the transmission rod 510 moves upward accordingly. When the transmission rod 510 moves upward, a negative pressure is generated inside it. This negative pressure will draw the sedative inside the storage tank 61 through the suction pipe 64, realizing the automatic replenishment of the sedative inside the guide cylinder 59, preparing for the next spray when the patient becomes agitated. Thus, a quantitative sedative can be automatically sprayed when the patient becomes agitated, quickly relieving the patient's agitation symptoms and stabilizing the patient's condition.
[0025] In an optional embodiment, the fixing component includes an adjusting screw 7 threaded to the bottom end of the clamping plate 1, a clamping member 8 fixedly connected to the top end of the adjusting screw 7, a guide groove being provided inside the clamping plate 1, and the clamping member 8 being slidably disposed along the guide groove. In use, the device is placed on a carrier such as a bed railing or the edge of a treatment bed, and the clamping member 8 is slid along the limiting groove inside the clamping plate 1 by rotating the adjusting screw 7. The device is fixed by the clamping action of the clamping member 8 and the clamping plate 1.
[0026] In an optional embodiment, the surface of the placement plate 2 is provided with a cushioning layer, and the bottom of the arc-shaped limiting member 45 is provided with multiple sets of cushioning airbags. Both the cushioning layer and the cushioning airbags are made of medical-grade flexible material. The airbags on the surface of the placement plate 2 provide soft support for the patient's upper arm, and the multiple sets of airbags at the bottom of the arc-shaped limiting member 45 can conform to the contour of the upper arm. The two work together to cushion the restraining pressure of the arc-shaped limiting member 45, avoiding skin pressure and damage caused by hard contact between the limb and the device when the patient is agitated. The medical-grade silicone material is skin-friendly, non-toxic, and wear-resistant, making it suitable for long-term restraint use by mental health patients. At the same time, it enhances the fit between the limb and the device and helps to improve the stability of the restraint.
[0027] In an optional embodiment, the limiting guide 47 is provided with a rolling component on the side near the guide plate 46. The rolling component rolls and fits against the side wall of the guide plate 46, and the rolling component is evenly distributed along the length direction of the limiting guide 47. The rolling ball reduces the friction between the limiting guide 47 and the guide plate 46, avoids sliding and jamming, and ensures that the arc-shaped limiting member 45 rises and falls smoothly.
[0028] In an optional embodiment, the power mechanism includes a sleeve 52 fixed to the surface of the guide plate 46, a lead screw 53 rotatably disposed inside the sleeve 52, a magnetic block 54 fixed to the outer wall of the lead screw 53, a piston 58 threaded to the outer wall of the lead screw 53, a magnetic ring 55 that magnetically engages with the magnetic block 54 sleeved on the outer wall of the sleeve 52, a toothed ring 56 fixed to the outer wall of the magnetic ring 55, a rack 57 that meshes with the toothed ring 56 fixed to one end of the limiting guide member 47, and the sleeve 52 and the guide cylinder 59 are connected by an air supply pipe 511.
[0029] In an optional embodiment, the sleeve 52 is provided with an axial limiting member, and the piston 58 is slidably disposed along the axial limiting member.
[0030] In an optional embodiment, the locking assembly includes a locking member 11 fixed to one end of the fixing ring 3, a socket is provided on one side of the placement plate 2, a pin 10 is slidably disposed in the socket, an operating plate 9 is fixedly connected to one end of the pin 10, a spring B12 is sleeved on the outer wall of the pin 10, and the two ends of the spring B12 are fixedly connected to the side wall of the placement plate 2 and the side wall of the operating plate 9 respectively, and the pin 10 and the locking member 11 are inserted and engaged.
[0031] In an optional embodiment, a liquid storage tank 61 is fixedly connected to the outer wall of the fixing ring 3. The liquid storage tank 61 and the guide cylinder 59 are connected by a suction pipe 64. Both the suction pipe 64 and the connecting pipe 65 are provided with unidirectional guide components.
[0032] In an optional embodiment, the spray pipe 62 has an arc-shaped structure that is adapted to the fixing ring 3, the spray element 63 is inclined upward, and the distance between two adjacent sets of spray elements 63 is consistent. The inclined upward setting of the spray element 63 can accurately spray the sedative near the patient's mouth and nose, which meets the clinical sedation needs and avoids spray deviation and waste.
[0033] Working principle: First, the patient places their upper arm on the air cushion on the surface of the placement plate 2. Then, the operator rotates the fixing ring 3 to limit the upper arm that needs to be restrained within the arc-shaped limiting member 45. Next, the operator pulls the operating plate 9, causing the pin 10 to slide and insert into the locking member 11 at one end of the fixing ring 3, thereby locking the fixing ring 3 and achieving initial fixation between the device and the patient's upper arm. After the device is installed, the operator can adjust the initial restraint force of the device through the adjusting member 42 according to the patient's specific condition. In specific operation, rotating the adjusting member 42 will cause the adjusting member 42 to engage with the fixed ring 3 due to the integrated thread. The cylinder 41 is threaded, and the rotating adjusting member 42 will move up and down along the vertical direction of the threaded cylinder 41. The up and down movement of the adjusting member 42 will drive the telescopic rod 43 connected to the bottom end through the bearing to rise and fall synchronously, thereby changing the initial compression degree of the spring A44 sleeved on the outer wall of the telescopic rod 43. The initial compression force of the spring A44 directly determines the initial constraint force of the arc-shaped limiting member 45 on the patient's upper arm, so as to adapt to the needs of different patients' conditions. When the patient's upper arm is inside the arc-shaped limiting member 45, the spring A44 is always in a compressed state, tightly pressing the arc-shaped limiting member 45 against the surface of the patient's upper arm, thereby achieving the constraint of the patient's upper arm movement.When a patient exhibits agitation, their upper arm will move within the limited space provided by the device's limiting mechanism. This movement directly acts on the arc-shaped limiting member 45, causing it to move upwards. As the arc-shaped limiting member 45 moves upwards, it simultaneously moves the limiting guide member 47. The rack 57, fixed to one end of the limiting guide member 47, will also move synchronously with the movement of the limiting guide member 47. Since the rack 57 and the toothed ring 56 are meshed, the linear movement of the rack 57 is converted into the rotational motion of the toothed ring 56. When the toothed ring 56 rotates, it causes the magnetic ring 55 to rotate synchronously. The rotational torque of the magnetic ring 55 is transmitted to the magnetic block 54 through magnetic force, causing the magnetic block 55 to rotate synchronously. 4. The synchronous rotation drives the lead screw 53 inside the sleeve 52 to rotate accordingly. During the rotation of the lead screw 53, the piston 58, guided by the limiting rod inside the sleeve 52, moves along the axial direction of the lead screw 53 towards both ends of the sleeve 52. The movement of the piston 58 will compress the gas inside the sleeve 52, increasing the gas pressure inside the sleeve 52. The compressed high-pressure gas is transported to the guide cylinder 59 through the gas delivery pipe 511. With the continuous input of gas, the gas pressure inside the guide cylinder 59 gradually increases. The increased gas pressure will generate a downward thrust on the transmission rod 510 inside the guide cylinder 59. The transmission rod 510 moves along the guide cylinder 59. As the internal vertical movement downwards occurs, the transmission rod 510 moves downwards, causing the clamping member 51 to move downwards synchronously. During this downward movement, the clamping member 51 exerts a continuous squeezing force on the spring A44, causing it to be rapidly compressed. As the compression of the spring A44 increases, its elastic restoring force also strengthens. This elastic restoring force acts in the opposite direction on the arc-shaped limiting member 45, simultaneously increasing the clamping and restraining force of the arc-shaped limiting member 45 on the patient's upper arm. During the downward movement of the transmission rod 510, it squeezes the sedative stored below the guide cylinder 59. The squeezed sedative is then transported through the connecting pipe 65 to the spray pipe 62, and then through the spray pipe 62... The evenly distributed spray nozzles 63 on the outer wall precisely and quantitatively spray the medication near the patient's nasal cavity. When the patient's agitation subsides and upper arm movement weakens, the elastic restoring force of the spring A44 pushes the arc-shaped limiting component 45 downwards to reset. This, in turn, through the limiting guide component 47, rack 57, and toothed ring 56, drives the magnetic ring 55, magnetic block 54, and lead screw 53 to rotate in the opposite direction, causing the piston component 58 to reset towards the center of the sleeve 52. The air pressure inside the guide cylinder 59 decreases, and the transmission rod 510 moves upwards accordingly. As the transmission rod 510 moves upwards, a negative pressure is generated inside it. This negative pressure draws the sedative from the reservoir 61 through the suction tube 64, achieving automatic replenishment of the sedative inside the guide cylinder 59.
