Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically refers to a restraint device for neurology nursing. Background Art

[0002] Neurological diseases mainly include Parkinson's disease, epilepsy, cerebral thrombosis, Alzheimer's disease, etc. When nursing neurological patients, especially epilepsy or Parkinson's patients, in order to prevent patients from causing harm to themselves or others, restraint chairs or beds are often used to control the patient's limbs. When in use, restraint belts are often used to restrain the patient on the chair or bed.

[0003] When the existing restraint devices restrain and fix patients, they only restrain the patient's limbs. After restraint, the patient's body can still move around at will, which poses a safety hazard; and during the restraint process, it is not easy to adjust the restraint strength of the patient. If the restraint is too tight, it will compress the restraint part of the patient, and long-term restraint will also cause discomfort to the patient, affecting blood circulation. If the restraint is too loose, it is easy to cause the restraint to fail, and the patient is more likely to break free. Moreover, after restraint, the patient's activity space cannot be adjusted, increasing the discomfort caused by restraint to the patient. Summary of the Invention

[0004] To solve the above existing problems, the present invention provides a restraint device for neurology nursing that restrains the patient as a whole and can autonomously adjust the restraint strength. Using the air pressure principle, after restraining the patient, the first airbag and the second airbag are cyclically inflated to closely adhere to and bind the patient's limbs, achieving the technical effect of adaptively adjusting the restraint strength of the patient's limbs, improving the patient's comfort, and solving the contradictory technical problem of the restraint force of the patient's limbs being both tight and loose. At the same time, the structure of cyclic inflation and deflation is adopted to avoid affecting blood circulation due to long-term restraint of the same part; in addition, a patient activity space is reserved on the bed to relieve the discomfort caused by restraint to the patient.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows: A restraint device for neurology nursing provided by the present invention includes a bed body. An upper limb restriction mechanism is provided at one end of the bed body. Hand restraint components and leg restraint components are respectively provided on the bed body. The hand restraint components and the leg restraint components are symmetrically arranged. The leg restraint components are arranged on the side of the hand restraint components away from the upper limb restriction mechanism. Cyclic restraint components are respectively provided on the hand restraint components and the leg restraint components; The leg restraint component includes a sliding frame, a bracket mechanism, and a leg locking mechanism. The sliding frames are symmetrically arranged at the lower part of the bed body. The bracket mechanism is slidably arranged in the sliding frame. The leg locking mechanism is arranged on the bracket mechanism; The cyclic restraint assembly includes a first airbag, a second airbag, and an intermittent inflation mechanism. The first airbag and the second airbag are symmetrically arranged at the inner ends of both sides of the leg locking mechanism and inside the hand restraint assembly respectively. The intermittent inflation mechanism is arranged on the leg locking mechanism and the hand restraint assembly respectively. An inflation tube is connected between the intermittent inflation mechanism and the first airbag and the second airbag respectively.

[0006] Further, hand activity grooves and leg activity grooves are symmetrically arranged on the bed body respectively, and the hand activity grooves and the leg activity grooves penetrate through the bed body respectively. The sliding frame is arranged below the leg activity groove. The leg locking mechanism includes a first bracket, a first cover plate, and a first magnet. The first bracket is movably arranged above the leg activity groove. The first cover plate is rotatably arranged on the first bracket. The inner walls of the first bracket and the first cover plate are combined to form a cylindrical shape. The first magnet is slidably arranged on the outer side wall of the first bracket. A first electromagnetic plate is arranged at the end of the first cover plate away from its rotating end. The first electromagnetic plate is inserted into the first bracket. A groove is arranged on the first electromagnetic plate. The first electromagnetic plate is movably engaged with the groove. When the first electromagnetic plate is energized, it generates magnetism, and its magnetic pole is different from that of the first magnet. The first electromagnetic plate adsorbs the first magnet to fix the first bracket and the first cover plate. When the first electromagnetic plate loses magnetism after being powered off, pulling the first magnet can release the fixation of the first bracket and the first cover plate.

[0007] Further, the support mechanism includes a follower rotating rod, a limit rotating rod, a telescopic sliding plate, a limit adjusting plate, and an adjusting insertion rod. The follower rotating rod and the limit rotating rod are respectively rotatably arranged at both lower ends of the first bracket. The limit rotating rod is arranged at one end of the first bracket close to the hand activity groove. A limiting groove is penetrated through the limit rotating rod. The follower rotating rod and the limit rotating rod are movably arranged in the leg activity groove. The telescopic sliding plate is horizontally arranged at the lower end of the follower rotating rod. The telescopic sliding plate is perpendicular to the follower rotating rod. The telescopic sliding plate slides inside the sliding frame. The limit adjusting plates are symmetrically arranged at the telescopic ends of the telescopic sliding plate. The limit rotating rod slides inside the symmetric limit adjusting plates. A plurality of adjusting holes are penetrated through the limit adjusting plates evenly. The adjusting insertion rod is movably inserted into the adjusting holes, and the adjusting insertion rod penetrates through the limiting groove.

[0008] During use, the height of the limiting rotating rod is restricted by adjusting the insertion rod. The insertion rod is inserted into the adjustment hole on the limiting adjustment plate, so that the movement range of the limiting rotating rod is between the insertion rod and the telescopic sliding plate. The patient can move by bending the leg. During the process of bending the leg, the lower leg drives the first bracket to rotate around the upper end of the follower rod. Driven by the upward movement of one end of the first bracket of the limiting rotating rod, it slides upward between the limiting adjustment plates. The first bracket slides towards the patient's hip, driving the entire bracket mechanism to slide in the leg activity groove. The telescopic sliding plate slides in the sliding frame and adapts to expand and contract. The patient can only perform up and down bending movements, restricting the left and right movement of the patient's leg and avoiding accidental injuries caused by the patient's violent activities.

[0009] Furthermore, the hand restraint assembly includes a second bracket and a second cover plate. The second bracket is movably arranged above the hand activity groove, and the second cover plate is rotatably arranged on the second bracket; the first airbag and the second airbag are respectively attached to both ends of the inner walls of the first bracket and the first cover plate and both ends of the inner walls of the second bracket and the second cover plate. The intermittent inflation mechanism is respectively arranged on the upper parts of the first cover plate and the second cover plate. The first airbag is circumferentially and uniformly communicated with a first insertion pocket on the side facing the second airbag. The second airbag is circumferentially and uniformly communicated with a second insertion pocket on the side facing the first airbag. The first insertion pocket and the second insertion pocket are staggered in the circumferential direction. A pressure strip is arranged inside the first insertion pocket and the second insertion pocket. The first airbag, the second airbag, the first insertion pocket, the second insertion pocket and the pressure strip are all made of rubber material, and soft materials are used to reduce the harm caused to the patient during restraint; Furthermore, the intermittent inflation mechanism includes a reversing motor, a turntable and an air pump. The reversing motor is respectively embedded in the upper parts of the first cover plate and the second cover plate. The turntable is arranged at the output end of the reversing motor, and the air pump is arranged on the upper part of the turntable; an air release channel and an inflation channel are respectively arranged inside the turntable. The air release channel and the inflation channel respectively penetrate the side wall and the upper wall of the turntable. The inflation channel is communicated with the output end of the air pump. The air release channel and the inflation channel are respectively communicated with symmetric inflation pipes. A compression cavity is communicated on the side of the inflation channel close to the air release channel. A pneumatic push plate is slidably arranged in the compression cavity. A spring is connected between the pneumatic push plate and the inner wall of the compression cavity. A pressure sensor is arranged on the inner wall of the compression cavity. The model of the pressure sensor is MS5803 pressure sensor. The spring is sleeved outside the pressure sensor; the air release channel penetrates the upper wall of the turntable and extends to be provided with an air release pipe. An air release groove is arranged on the outer wall of the air release pipe. An air release floating plate is slidably arranged in the air release pipe; When in use, the inflation channel and the deflation channel are respectively connected to the symmetric inflation tubes. If the inflation channel is connected to the second airbag bag at this time and the air pump works, air is inflated into the second airbag bag and the second insertion bag through the inflation channel. The second airbag bag and the second insertion bag gradually expand. During the expansion process, they squeeze the first insertion bag and gradually fit with the patient's limbs. The rubber strip presses tightly against the patient's skin, providing strong friction and strengthening the fixation effect on the patient's limbs. The gas squeezed out from the first insertion bag flows through the deflation channel to the deflation tube. The gas lifts the deflation float plate and is discharged from the deflation slot. During this period, after the second airbag bag and the second insertion bag are inflated and tightly attached to the patient's limbs, the gas gradually saturates, and then squeezes the pneumatic push plate, pushing the pneumatic push plate to slide in the compression cavity against the elasticity of the spring. When the pneumatic push plate slides to the pressure sensor, the flipping motor starts, causing the turntable to rotate 180 degrees. As a result, the inflation tube connecting the inflation channel to the first airbag bag is connected, and the deflation tube connecting the deflation channel to the second airbag bag is connected. The deflation float plate falls to the lower end of the deflation tube under the action of gravity, blocking the deflation channel to prevent the instantaneous deflation of the gas in the second airbag bag and the second insertion bag, weakening the restraint force. The pneumatic push plate returns to the end of the compression cavity away from the pressure sensor under the elastic action of the spring. Immediately afterwards, the air pump inflates the first airbag bag and the first insertion bag through the inflation channel. The first airbag bag and the first insertion bag inflate and expand. During this process, the first insertion bag squeezes the second insertion bag, and the gas in the second insertion bag pushes the deflation float plate to move up and then flows out from the deflation slot. At this time, the strip on the first insertion bag presses tightly against the patient's skin, and the first insertion bag squeezes the patient's limbs for fixation. This cycle repeats; the structure of cyclic inflation and deflation avoids affecting blood circulation by restraining the same part for a long time, and at the same time avoids the large restraint force on the patient's limbs caused by the continuous inflation of the air pump, which affects the blood circulation of the patient. Through the change of air pressure, the restraint force on the patient's limbs is adaptively adjusted, improving the comfort of the patient's use and solving the contradictory technical problem of the restraint force on the patient's limbs being both tight and loose.

[0010] Further, a second magnet is slidably provided on the outer side wall of the second bracket, and a second electromagnetic plate is provided at a position far from the rotation end of the second cover plate.

The hand pad is provided at the end of the second bracket, and the pressure pad is provided at the end of the second cover plate. The pressure pad is arranged above the hand pad. A nursing groove is penetrated through the inner side of the pressure pad. The hand pad and the pressure pad clamp the patient's hand to prevent the patient's hand from moving around randomly and increasing the difficulty of infusion care. When the patient needs infusion care, the infusion operation can be performed on the back of the hand through the nursing groove on the pressure pad. The transition rod is movably arranged at the lower part of the second bracket and slides in the hand activity groove. A return spring is connected between the transition rod and the inner wall of the hand activity groove. The movable cover is arranged at the lower end of the transition rod. The fixing plate is arranged at the lower part of the bed body and symmetrically arranged on both sides of the hand activity groove. The fixing insertion rod is movably inserted into the fixing plate. A rotating shaft is rotatably arranged inside the movable cover, and a fixing convex block is arranged inside the rotating shaft. A torsion spring is connected between the rotating shaft and the movable cover. An activity belt is wound around the rotating shaft. The activity belt penetrates through the inside of the transition rod and is connected to the second bracket. The activity belt does not have elasticity, and the length of the activity belt does not exceed the normal activity range of the patient. In the initial state, the movable cover is inside the symmetric fixing plates, the torsion spring makes the activity belt taut, the fixing insertion rod penetrates through the inside of the rotating shaft, and the upper part of the fixing insertion rod is engaged with the fixing convex block to fix the rotating shaft. Further, the upper limb restricting mechanism includes a fixed cylinder, a connecting rod, a telescopic pull plate, a chest and abdomen pressing plate, a pull rod, a restricting plate, and a limiting bolt. The restricting plate is arranged at the end of the bed body far from the leg activity groove.

The fixed cylinders are symmetrically sleeved on the ends of the bed body, and the fixed cylinders are rotatably connected to the bed body.

[0011] Preferably, a main controller is provided on the bed body. The model of the main controller is S7-200. The first electromagnetic plate, the second electromagnetic plate, the flipping motor, the air pump, and the pressure sensor are respectively electrically connected to the main controller.

[0012] The beneficial effects achieved by the present invention with the above structure are as follows: 1. A restraint device for neurology nursing provided by the present invention preliminarily limits the overall body of the patient through the upper limb limiting mechanism, and restrains the limbs of the patient through the hand restraint component and the leg restraint component respectively. After the overall restraint of the patient, the patient cannot move around randomly, avoiding harm to the patient himself and the medical staff; 2. A cyclic restraint component is provided. Using the principle of air pressure, after restraining the patient, the first airbag and the first insertion bag and the second airbag and the second insertion bag are cyclically inflated to tightly adhere to and restrain the limbs of the patient. When the first insertion bag is inflated, the second insertion bag is squeezed to deflate, and when the second insertion bag is inflated, the first insertion bag is squeezed to deflate.

The structure of cyclic inflation and deflation is adopted to avoid affecting blood circulation by restraining the same part for a long time, and the pneumatic push plate automatically judges inflation and deflation, achieving the technical effect of adaptively adjusting the restraint force on the limbs of the patient, improving the comfort of the patient's use, and solving the contradictory technical problem of the restraint force on the patient's limbs being both tight and loose; The soft first airbag and the first insertion bag and the second airbag and the second insertion bag are used together to restrain the limbs of the patient, reducing the harm caused to the patient during restraint; 3. A nursing groove is provided on the hand restraint component to press and limit the finger part of the patient, facilitating the infusion operation of the medical staff during nursing and avoiding the situation where the finger part of the patient moves randomly and makes it difficult to infuse; 4. To prevent the patient from always maintaining one state during restraint, which may cause poor blood circulation in the patient and make the patient more irritable, an activity belt is provided on the hand restraint component and a bracket mechanism is provided on the leg restraint component. When the patient needs to move the limbs during restraint, the patient can move under the restriction of the activity belt and the limit rotating rod, enabling the patient to move the limbs within the restricted range adjusted by the medical staff, relieving the irritable psychology caused by restraint, avoiding discomfort caused to the patient during restraint, and at the same time restricting the patient's movement so that the patient will not cause harm to others and himself during movement.

The first cover plate 222 and the first bracket 221, as well as the second cover plate 32 and the second bracket 31, are all in a state of being rotatably opened. The first airbag 41, the second airbag 42, the first insertion pocket 43, and the second insertion pocket 44 are not inflated and are all in a deflated state.

[0026] During specific use, medical staff guide the patient to lie flat on the bed body 1. First, the limit bolt 57 is pulled out from the limiting plate 56, and the connecting rod 52 is flipped so that the chest and abdomen pressing plate 53 presses down to the patient's chest and abdomen. The cotton pad on the chest and abdomen pressing plate 53 naturally fits with the patient's chest and abdomen, while the telescopic pull plate 54 symmetrically located with the connecting rod 52 lifts, driving the pull rod 55 to slide on the limiting plate. The telescopic pull plate 54 adapts and expands or contracts. Subsequently, the limit bolt 57 is passed through the pull rod 55 and inserted into the jack on the limiting plate 56, thereby positioning the position of the chest and abdomen pressing plate 53 and preliminarily restraining the patient.

[0027] Immediately start the main controller, spread the patient's limbs, place the patient's hands on the second bracket 31 respectively, and place the patient's legs on the first bracket 221 respectively. Among them, it is necessary to place the patient's hands on the pressure pad 34, and place the part of the patient's lower leg near the ankle on the first bracket 221. Then rotate the first cover plate 222 and the second cover plate 32 respectively, so that the first electromagnetic plate 224 and the second electromagnetic plate are inserted into the first bracket 221 and the second bracket 31 respectively. After being energized, the first electromagnetic plate 224 and the second electromagnetic plate generate magnetism, and then adsorb the first magnet 223 and the second magnet 36, so that the first magnet 223 is engaged with the first electromagnetic plate 224, and the second magnet 36 is engaged with the second electromagnetic plate. Under the adsorption of magnetic force, it is more difficult for the patient to break free. At this time, the first bracket 221 and the first cover plate 222 clamp the patient's lower leg part, the second bracket 31 and the second cover plate 32 clamp the patient's forearm part, and the hand pad 33 and the pressure pad 34 clamp the patient's hand to prevent the patient's hand from moving around and increasing the difficulty of infusion care. When the patient needs infusion care, the back of the hand can be infused through the care groove 35 on the pressure pad 34 to complete the preliminary restraint of the patient. Compared with the restraint process in which medical staff wrap the restraint belt around the patient multiple times and then tie the restraint belt, this restraint process takes less time and reduces the harm caused to medical staff or the patient himself during restraint.

[0028] The main controller starts the air pump 463, the flipping motor 461 and the pressure sensor 4610. The inflation channel 464 and the deflation channel 465 are respectively connected to the symmetric inflation tubes 45. If the inflation channel 464 is connected to the second airbag 42 at this time, the air pump 463 works, and inflates the second airbag 42 and the second insertion pocket 44 through the inflation channel 464. The second airbag 42 and the second insertion pocket 44 gradually expand, and squeeze the first insertion pocket 43 during the expansion process and gradually fit with the patient's limbs. The rubber strip 47 closely adheres to the patient's skin, providing strong friction and strengthening the fixing effect on the patient's limbs. At the same time, the soft second airbag 42 and the second insertion pocket 44 reduce the harm caused to the patient during restraint. The gas squeezed out from the first insertion pocket 43 flows through the deflation channel 465 to the deflation tube, the gas lifts the deflation floating plate 467, and is discharged from the deflation groove 466. During this period, after the second airbag 42 and the second insertion pocket 44 are inflated and closely adhere to the patient's limbs, the gas gradually saturates, and then squeezes the pneumatic push plate 468, pushing the pneumatic push plate 468 to slide in the compression chamber 469 against the elasticity of the spring. When the pneumatic push plate 468 slides to the pressure sensor 4610, the flipping motor 461 starts, rotates the turntable 462 by 180 degrees, and then connects the inflation channel 464 to the inflation tube 45 connected to the first airbag 41, and the deflation channel 465 to the inflation tube 45 connected to the second airbag 42. The deflation floating plate 467 falls to the lower end of the deflation tube under the action of gravity, blocking the deflation channel 465 to prevent the gas in the second airbag 42 and the second insertion pocket 44 from instantaneously deflating and weakening the restraint force. The pneumatic push plate 468 returns to the end of the compression chamber 469 away from the pressure sensor 4610 under the elastic action of the spring. Immediately afterwards, the air pump 463 inflates the first airbag 41 and the first insertion pocket 43 through the inflation channel 464. The first airbag 41 and the first insertion pocket 43 inflate and expand. During this process, the first insertion pocket 43 squeezes the second insertion pocket 44, and the gas in the second insertion pocket 44 pushes the deflation floating plate 467 to move up and then flows out from the deflation groove 466. At this time, the strip 47 on the first insertion pocket 43 closely adheres to the patient's skin, and the first insertion pocket 43 squeezes the patient's limbs for fixation, and so on in a cycle; the structure of cyclic inflation and deflation avoids affecting blood circulation by restraining the same part for a long time, and at the same time avoids the continuous inflation of the air pump 463 from causing a large restraint force on the patient's limbs and affecting the blood circulation of the patient. By changing the air pressure, the restraint force on the patient's limbs is adaptively adjusted, improving the comfort of the patient's use, and solving the contradictory technical problem that the restraint force on the patient's limbs needs to be both tight and loose.

[0029] When it is necessary to release the restraint, the medical staff pumps air through the air pump 463 to extract the gas in the first airbag 41 or the second airbag 42. After the gas decreases, the first airbag 41, the first insertion bag 43, the second airbag 42, and the second insertion bag 44 are compressed. Subsequently, the main controller is turned off, causing the first electromagnetic plate 224 and the second electromagnetic plate to lose power and magnetism, and no longer attracting the first magnet 223 and the second magnet 36. The medical staff pulls the first magnet 223 and the second magnet 36 outwards respectively, no longer restricting the first electromagnetic plate 224 and the second electromagnetic plate. Then, the first cover plate 222 and the second cover plate 32 are rotated and opened respectively to release the restraint on the patient's limbs. Finally, the limit bolt 57 is pulled out, and the chest and abdomen pressing plate 53 is flipped up to release the restraint on the patient's upper body.

[0030] To prevent the patient from always maintaining one position during restraint and making the patient more irritable, the activity ranges of the hand restraint assembly 3 and the leg restraint assembly 2 can be appropriately adjusted; by adjusting the insertion rod 216 to limit the activity height of the limit rotating rod 212, the insertion rod 216 is inserted into the adjustment hole 215 on the limit adjustment plate 214, so that the activity range of the limit rotating rod 212 is within the distance between the adjustment insertion rod 216 and the telescopic sliding plate 213. The patient can move by bending the legs. During the process of bending the legs, the lower leg drives the first bracket 221 to rotate around the upper end of the follower rod 211. Driven by the upward movement of one end of the limit rotating rod 212 on the first bracket 221, it slides upward between the limit adjustment plates 214. The first bracket 221 slides towards the patient's buttocks, driving the entire bracket mechanism 21 to slide in the leg activity groove 11. The telescopic sliding plate 213 slides in the sliding frame 23 and adapts to telescopic movement. The patient can only make up and down bending movements, restricting the left and right movement of the patient's legs and avoiding accidental injuries caused by the patient's violent activities. The fixed insertion rod 310 is pulled out from the fixed plate 39. The fixed insertion rod 310 no longer restricts the rotating shaft 312 and the movable cover 38. Thus, the movable belt 313 can be pulled out from the transition rod 37. The rotating shaft 312 rotates, and the torsion spring is compressed. The movable belt 313 has no elasticity. The patient's arm can move within the range where the movable belt 313 extends while being restrained by the second bracket 31 and the second cover plate 32. The length of the movable belt 313 does not exceed the normal activity range of the patient, alleviating the irritable psychology caused by restraint, avoiding discomfort caused to the patient during restraint, and at the same time preventing the patient from causing harm to others and himself during activities. When the patient does not need to move, the patient's arm is pressed down. Under the action of the torsion spring, the rotating shaft 312 winds up the movable belt 313, causing the second bracket 31 to fit with the transition rod 37 again. Under the elastic action of the return spring 311, the movable cover 38 slides between the fixed plates 39, and the fixed insertion rod 310 is inserted again to position the rotating shaft 312.

[0031] It should be noted that flexible sealing sleeves are provided at the ends of the inflation channel 464 and the deflation channel 465, so that no gas leakage will occur when they rotate to the inflation tube 45 for inflation and deflation. This is prior art and will not be elaborated here.
