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 caring for neurological patients, especially those with epilepsy or Parkinson's disease, in order to prevent the 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 to a chair or bed.

[0003] When restraining and fixing a patient, the existing restraint device only restrains the patient's limbs. After being restrained, the patient's body can still move around at will, which poses a safety hazard. Moreover, during the restraint process, the restraint strength of the patient is difficult to adjust. If the restraint is too tight, it will press on the restrained part of the patient. Long-term restraint will also cause discomfort to the patient and affect blood circulation. If the restraint is too loose, it will easily cause the restraint to fail, and the patient will be more likely to break free. Moreover, after being restrained, the patient's activity space cannot be adjusted, which increases the patient's discomfort caused by the restraint. Summary of the Invention

The upper part of the fixed plug rod 310 is engaged with the fixed protrusion 314, so that the rotating shaft 312 is positioned and cannot rotate, so that the second bracket The frame 31 fits with the upper end of the transition rod 37; the adjusting rod 216 is inserted into the adjusting hole 215 at the lower end, and the adjusting rod 216 passes through the limiting groove of the limiting rotating rod 212. At this time, the adjusting rod 216 is at the lower end of the limiting groove, thereby making the first bracket 221 horizontal; the first cover plate 222 and the first bracket 221 and the second cover plate 32 and the second bracket 31 are all in a rotated open state, and the first airbag bag 41, the second airbag bag 42, the first insert bag 43 and the second insert bag 44 are not inflated and are all in a deflated state.

[0050] During specific use, the medical staff guides the patient to lie flat on the bed 1. First, the limit bolt 57 is pulled out from the limiting plate 56, and the connecting rod 52 is flipped over to press the chest and abdominal compression plate 53 down to the patient's chest and abdomen. The cotton pad on the chest and abdominal compression plate 53 naturally fits the patient's chest and abdomen, and the telescopic pull plate 54 symmetrical to the center of the connecting rod 52 is lifted up, driving the pull rod 55 to slide on the limit plate. The telescopic pull plate 54 adaptively retracts and retracts, and then the limit bolt 57 is passed through the pull rod 55 and inserted into the socket on the limiting plate 56, thereby positioning the chest and abdominal compression plate 53 and preliminarily restraining the patient.

[0051] Then 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, wherein the patient's hands need to be placed on the pressure pad 34, and the patient's calf near the ankle is placed on the first bracket 221, and then the first cover plate 222 and the second cover plate 32 are rotated 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, and the first electromagnetic plate 224 and the second electromagnetic plate generate magnetism after power is turned on, and then the first magnet 223 and the second magnet 36 are attracted, so that the first magnet 223 is engaged with the first electromagnetic plate 224, and the second magnet 36 is engaged with the first electromagnetic plate 224. The two electromagnetic plates are engaged, and the magnetic attraction increases the difficulty for the patient to break free. At this time, the first bracket 221 and the first cover plate 222 clamp the patient's calf, the second bracket 31 and the second cover plate 32 clamp the patient's forearm, 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 infusion operation can be performed on the back of the hand through the care groove 35 on the pressure pad 34 to complete the initial restraint of the patient. Compared with the restraint process in which medical staff use a restraint belt to wrap the patient multiple times and then tie the restraint belt, this restraint process is short in time, which reduces the harm caused to medical staff or themselves by the patient during restraint.

[0052] The main controller starts the air pump 463, the flip motor 461 and the pressure sensor 4610, and the inflation channel 464 and the deflation channel 465 are respectively connected to the symmetrical inflation tube 45. If the inflation channel 464 is connected to the second air bag 42 at this time, the air pump 463 works and inflates the second air bag 42 and the second insert bag 44 through the inflation channel 464. The second air bag 42 and the second insert bag 44 gradually expand, squeezing the first insert bag 43 during the expansion process and gradually fitting with the patient's limbs. The rubber pressure strip 47 is close to the patient's skin, providing strong friction and strengthening the fixation effect on the patient's limbs. At the same time, the soft second air bag 42 and the second insert bag 44 reduce the damage caused to the patient during restraint. The gas squeezed out from the first insert bag 43 flows to the deflation pipe through the deflation channel 465. The gas lifts the deflation float 467 and is released from the deflation groove 466. During this period, after the second airbag bag 42 and the second insert bag 44 are inflated and pressed against the patient's limbs, the gas gradually becomes saturated, and then squeezes the pneumatic push plate 468, pushing the pneumatic push plate 468 to overcome the elasticity of the spring and slide in the compression chamber 469. When the pneumatic push plate 468 slides to the pressure sensor 4610, the flip motor 461 is started to rotate the turntable 462 180 degrees, thereby making the inflation channel 464 and the first airbag The air bag 41 is connected to the inflation tube 45, and the deflation channel 465 is connected to the inflation tube 45 connected to the second air bag 42. The deflation float 467 falls to the lower end of the deflation tube under the action of gravity, blocking the deflation channel 465, preventing the gas in the second air bag 42 and the second insert bag 44 from being instantly deflated, thereby weakening the restraint force. The pneumatic push plate 468 is moved away from the pressure sensor 4610 and reset to the end of the compression chamber 469 under the elastic action of the spring. Then the air pump 463 inflates the first air bag 41 and the first insert bag 43 through the inflation channel 464. The first air bag 41 and the first insert bag 43 are inflated and expanded. In this process, the first insert bag 43 squeezes the second insert bag 44, and the gas in the second insert bag 44 pushes the deflation float 467 to move up and then flows out from the deflation groove 466. At this time, the pressure strip 47 on the first insert bag 43 is close to the patient's skin, and the first insert bag 43 squeezes the patient's limbs to fix them, thus circulating; the cyclic inflation and deflation structure avoids long-term restraint of the same part affecting blood circulation, and at the same time avoids the continuous inflation of the air pump 463 causing a large restraint force on the patient's limbs, affecting the patient's blood circulation. Through the change of air pressure, the restraint force on the patient's limbs is adaptively adjusted, the patient's comfort is improved, and the contradictory technical problem of the restraint force on the patient's limbs being both tight and loose is solved.

[0053] When the restraint needs to be released, the medical staff uses the air pump 463 to draw air out of the first airbag bag 41 or the second airbag bag 42. After the gas is reduced, the first airbag bag 41, the first insert bag 43, the second airbag bag 42 and the second insert bag 44 are compressed, and then the main controller is turned off to cut off the power to the first electromagnetic plate 224 and the second electromagnetic plate and lose their magnetism, and no longer attract the first magnet 223 and the second magnet 36. The medical staff pull the first magnet 223 and the second magnet 36 outward respectively, no longer restricting the first electromagnetic plate 224 and the second electromagnetic plate, and then rotate and open the first cover plate 222 and the second cover plate 32 respectively to release the restraint on the patient's limbs, and finally pull out the limit bolt 57, flip and lift the chest and abdominal compression plate 53 to contact the restraint on the patient's upper body.

[0054] In order to prevent the patient from always remaining in one state during restraint, which makes the patient more irritable, the range of motion 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 movable height of the limit rotating rod 212, the adjustment insertion rod 216 is inserted into the adjustment hole 215 on the limit adjustment plate 214, so that the range of motion of the limit rotating rod 212 is within the distance between the adjustment insertion rod 216 and the telescopic sliding plate 213, and the patient can move by bending the leg. In the process of bending the leg, the calf drives the first bracket 221 to rotate around the upper end of the follower rotating rod 211, and the first bracket 221 of the limit rotating rod 212 is driven by the upper end to slide upward between the limit adjustment plates 214, and the first bracket 221 slides toward the patient's buttocks, driving the bracket mechanism 21 as a whole to slide in the leg movable groove 11, and the telescopic sliding plate 213 slides and adaptively retracts in the sliding frame 23, so that the patient can only bend up and down, limiting the left and right movement of the patient's legs, and avoiding accidental injuries caused by strenuous activities of the patient;

[0055] When the arm 31 is in the upright position, the second arm 31 is pulled out of the upright position, and the arm 31 is pulled out of the upright position, so that the arm 31 is pulled out of the upright position, and the arm 31 is pulled out of the upright position, so that the arm 31 is pulled out of the upright position, and the arm 31 is pulled out of the upright position, so that the arm 31 is pulled out of the upright position, and the arm 31 is pulled out of the upright position, so that the arm 31 is pulled out of the upright position,

[0056] It is worth noting that the ends of the inflation channel 464 and the deflation channel 465 are both provided with flexible sealing sleeves, which will not cause gas leakage when they are rotated to the inflation tube 45 for inflation and deflation. This is existing technology and will not be repeated here.

[0057] The above is the overall workflow of the present invention. Just repeat this step next time you use it.
