Description

Technical Field

[0001] The present invention relates to the technical field of restraint devices, and in particular to a multifunctional medical limb restraint protection device. Background Art

[0002] In hospitals, before treating injured patients, in order to ensure the accuracy and effectiveness of the treatment, it is usually necessary to let the patients lie flat on the bed and observe the injuries carefully. However, the specific time for observing the injuries varies depending on the patient's injuries. In some cases, the time for observing the injuries may be longer. During this period, patients tend to move their bodies unconsciously due to maintaining the same posture for a long time, or due to boredom, wound pain, etc. This not only interferes with the doctor's observation, but may also affect the formulation of subsequent treatment plans. Therefore, medical staff will use tools such as restraints to securely fix the patient on the bed to ensure the smooth progress of the observation process.

[0003] Most of the existing restraint and fixation methods for patients are to restrain the abdomen and limbs through restraint belts. Although they can basically adapt to most situations, for patients with abdominal injuries, even if the wound is carefully avoided during fixation, the above-mentioned fixation method will still exert pressure on the area around the wound, thereby having a negative impact on the patient's abdominal wound. If the abdominal wound is located on the side, doctors often require the patient to lie on his side when assessing the injury. However, due to the abdominal injury, the patient will find it difficult to turn over and it is difficult to maintain the side-lying position for a long time. In addition, due to the fixation of the patient's abdomen by the restraint belt, the force on the patient's upper and lower limbs may become uneven when the patient turns over, which increases the risk of spraining the body when the patient turns over, and is not practical. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the conventional restraint and fixation methods in the prior art, when applied to patients with abdominal injuries, are likely to affect the patient's wound and are not conducive to the turning over of patients with abdominal wounds on the side, and to propose a multifunctional medical limb restraint protection device.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a multifunctional medical limb restraint protection device, comprising a bed, a cavity is opened at the bottom of the bed, a vertical through groove and a horizontal through groove are penetrated on the top wall of the cavity, a pillow is placed on the top of the bed, the vertical through groove is located between the horizontal through groove and the pillow, and further comprising: An adjustable restraint mechanism, which is arranged on the bed and is used to restrain patients of different body sizes; An abdominal protection mechanism, which is arranged on the top of the bed and is used to prevent infection at the wound of a patient with an abdominal injury and to limit the twisting angle of the patient's abdomen; A first auxiliary mechanism and a second auxiliary mechanism, wherein the first auxiliary mechanism is arranged on the hospital bed and the vertical through groove, and is used to improve the comfort of the patient's back and waist; the second auxiliary mechanism is arranged on the hospital bed and the horizontal through groove, and is used to improve the comfort of the patient's legs and improve the safety of the patient when turning over.

[0006] Compared with the prior art, the advantages of the present invention are: 1. The present invention can not only avoid affecting the wound of the patient with abdominal injury while realizing effective restraint on the patient through the mutual cooperation of adjusting the restraint mechanism, the abdominal protection mechanism, the first auxiliary mechanism and the second auxiliary mechanism, but also can realize automatic turning of the patient when the patient's abdominal wound is located on the side and the patient is turned over for the convenience of observation by slightly adjusting the patient's lower limbs, retracting and unreeling the chest restraint belt and the hip restraint belt, raising and lowering the first roller located in the direction of the patient's turning over, and moving the second airbag and its flexible contact with the patient's legs, so as to effectively improve the safety of the patient in the turning process, avoid the patient from suffering secondary injury in the turning process, and thus effectively improve its wide applicability.

[0007] 2. The present invention, through the mutual cooperation of the first auxiliary mechanism, the second auxiliary mechanism and the inflation and deflation mechanism, can utilize the first air pump and the second air pump after being turned on to inflate and deflate each air cushion to achieve massage of the waist, back and legs of the patient lying flat and restrained on the bed (i.e., simulating the effect of artificial massage through inflation and deflation operations), thereby promoting the patient's blood circulation, which can not only improve the patient's comfort lying on the bed, but also help alleviate the local compression and poor blood circulation problems that may be caused by the patient lying on the bed for a long time.

[0008] 3. The present invention can adjust the coordination between the restraint mechanism and the abdominal protection mechanism to restrain and turn over the patient who is emotionally agitated or suffering from rage disorder. The contact and adsorption between the first electromagnet on the abdominal restraint belt and the magnet on the limiting belt can be used to quickly and effectively restrict the patient who may have difficulty in controlling his body movements and may turn over at an angle beyond the safe range, thereby preventing the patient from causing an accident due to excessive turning over. The slow winding of the winding roller and the separation of the first electromagnet and the magnet can be used to gradually restore the patient to a lying position, thereby effectively ensuring the patient's safety.

[0009] 4. The present invention, through the setting of each airbag in the first auxiliary mechanism and the second auxiliary mechanism and the inflation operation of the airbag by the inflation and deflation mechanism, can not only flexibly limit the patient when the patient lies flat on the bed, effectively preventing the patient from falling out of bed and other accidents, but also enable the patient to move within a small range when being restrained, and can also reduce the twisting and displacement of the spine during the patient's turning over, and after the patient turns over, reasonably support the patient's waist, back and legs, effectively disperse the pressure of the patient's body on the bed surface, avoid long-term pressure on local tissues, thereby effectively improving the safety and comfort of the patient after turning over.

[0022] In the present invention, when the patient has a wound on the abdomen, the present invention can be used to restrain the body in different areas. When restraining the patient, first let the patient lie on the bed 1, and then adjust the chest restraint belt 3 and the hip restraint belt 4 to suitable positions by controlling the sliding part 37 according to the patient's body shape, and at the same time adjust the wrist restraint belt 24 and the ankle restraint belt 9 to suitable positions by controlling the first moving part and the second moving part respectively. Since the position of the first leg air cushion 12 in the longitudinal direction is constant, according to the patient's body shape and the position of the first leg air cushion 12, and with the waist air cushion 6 as a reference, the waist air cushion 6 is moved to a suitable position. In this process, the waist air cushion 6 moves synchronously with the back air cushion 19 (the distance between the waist air cushion 6 and the back air cushion 19 is preset to be the distance between the waist and back of a conventional patient).

[0023] Specifically, the two second electromagnets 44 are started (under normal circumstances, the second electromagnets 44 and the first sliding block 43 are in contact). Since the first sliding block 43 is made of magnetic material, the two second electromagnets 44 will adsorb the two first sliding blocks 43 respectively after being started, so that the first fixed block 40 is connected to the first sliding block 43. Then, the first motor 25 is controlled to rotate the second screw rod 26, so that the first sliding block 43 and the first fixed block 40 connected to the first sliding block 43 move, thereby causing the waist air cushion 6 and the back air cushion 19 on the two third support plates 21 to move synchronously. After the waist air cushion 6 moves to a suitable position, the patient lies flat on the bed 1, and the patient's waist corresponds to the position of the waist air cushion 6 (at this time, the patient's legs are located at the first leg air cushion 12 and the second leg air cushion 13). Under normal circumstances, the position of the back air cushion 19 at this time will correspond to the patient's back. At this time, it is only necessary to lock the telescopic state of the telescopic plate 28 by the locking part and fix the position of the waist air cushion 6 and the back air cushion 19.

[0024] If the position of the back air cushion 19 does not completely correspond to the patient's back, it means that the position of the patient's back is beyond the preset range. At this time, you only need to turn off the second electromagnet 44 corresponding to the position of the waist air cushion 6, and then control the first motor 25 again, so that the back air cushion 19 moves away from the waist air cushion 6 under the action of the first fixed block 40 thereon and the corresponding second electromagnet 44, until the position of the back air cushion 19 corresponds to the patient's back. During the movement of the back air cushion 19, the telescopic plate 28 thereon will also telescope accordingly. After the back air cushion 19 is moved, the telescopic state of the telescopic plate 28 is locked by the locking part, and the position of the waist air cushion 6 and the back air cushion 19 are fixed.

[0025] After completing the above work, the medical staff takes out an abdominal restraint belt 5 of appropriate length according to the patient's body shape, and cuts multiple openings on the abdominal restraint belt 5, and at the same time cuts a notch according to the position of the patient's abdominal wound. The abdominal restraint belt 5 is plugged with two symmetrical limiting belts 32 through the multiple openings, and is detachably mounted on two electric sliders through the two limiting belts 32. The abdominal restraint belt 5 is then moved to the patient's abdominal position by controlling the two electric sliders, and is wrapped around the patient's abdomen. At this time, the notch on the abdominal restraint belt 5 exposes the patient's abdominal wound, and then the observation window 18 is glued to the notch on the abdominal restraint belt 5 with medical glue (the abdominal restraint belt 5 is a disposable item to ensure hygiene and safety).

[0026] On the one hand, the observation window 18 is convenient for the doctor to observe the condition of the wound. On the other hand, when the doctor is not at the bedside or dealing with other matters, the observation window 18 can serve as a protective barrier to reduce the contact between the wound and the outside air, which helps to reduce the risk of wound infection. Afterwards, the two wrist restraints 24 and the two ankle restraints 9 are respectively placed on the patient's two wrists and two ankles, and then the patient's arms are naturally placed on the third airbag 20. The third airbag 20 can provide comfortable support for the patient's hands and relieve hand fatigue caused by long-term bed rest. At this time, the first elastic band in the placement frame is pulled out. Because it is elastic and its length is set according to the normal patient arm length, the patient's arms can remain natural and relaxed when placed, and at the same time are properly restrained and supported to prevent them from affecting the doctor's observation or injury due to unconsciousness or excessive activity.

[0027] Then, the two ends of the chest restraint belt 3 are respectively removed from the clamping parts on the corresponding winding rollers 39, and after unfolding, they are wound around the patient's chest. Then, the smaller width fixing belt on the chest restraint belt 3 is passed through the through hole on the larger width fixing belt, and then the two ends of the chest restraint belt 3 are respectively passed through the two through grooves and clamped and fixed by the clamping parts on the corresponding winding rollers 39. After completing the initial restraint of the patient by the chest restraint belt 3, since the crotch restraint belt 4 and the chest restraint belt 3 have the same structure, and the movable tightening group on the crotch restraint belt 4 has the same structure as the movable tightening component on the chest restraint belt 3, the above operation is repeated. However, the height of the chest restraint belt 3 and the hip restraint belt 4 at the contact point with the corresponding first roller 35 can be adjusted by controlling the electric telescopic rod 36 to make them slightly lower than the upper surface of the patient's body, and then the second motor 29 is started to rotate the winding roller 39, and the chest restraint belt 3 and the hip restraint belt 4 are wound up, so that the chest restraint belt 3 and the hip restraint belt 4 slightly compress the shoulders and hips, thereby completing the restraint of the patient's upper limbs. At the same time, the chest restraint belt 3 can also limit the patient's arms to keep them in a relatively fixed position, preventing the arms from making excessive movements, thereby ensuring the stability and safety of the patient during the doctor's observation.

[0028] After completing the restraint of the patient, start the second air pump 41 and open the electric valves 23 on the multiple shunt tubes 22 on the trachea connected thereto, so that the second air pump 41 inflates the waist air cushion 6 and the back air cushion 19 through the delivery hose 42, so that the waist air cushion 6 and the back air cushion 19 swell and support the patient's waist and back. At the same time, start the first air pump 17 and open the electric valves 23 on the multiple shunt tubes 22 on the trachea connected thereto, so that the first air pump 17 inflates the first leg air cushion 12 and the second leg air cushion 13 through the delivery hose 42, so that the first leg air cushion 12 and the second leg air cushion 13 swell and support the patient's legs.

[0029] When the waist air cushion 6 and the back air cushion 19 support the patient, the waist air cushion 6 and the back air cushion 19 can be inflated and deflated by controlling the electric valve 23. When one of the waist air cushions 6 is deflated, the other waist air cushion 6 remains unchanged, and the back air cushion 19 on the same side of the deflated waist air cushion 6 remains unchanged, and the back air cushion 19 on the diagonal of the deflated waist air cushion 6 is deflated. Then the opposite operation is performed, that is, the originally deflated waist air cushion 6 and back air cushion 19 are re-inflated, and the inflated waist air cushion 6 and back air cushion 19 begin to deflate. The above process is performed alternately, thereby simulating the artificial massage effect and promoting blood circulation in the patient's waist and back. This not only improves the comfort of the patient lying on the bed 1, but also helps to alleviate the local compression and poor blood circulation problems that may be caused by the patient lying on the bed 1 for a long time.

[0030] By always keeping a group of diagonal waist air cushions 6 and back air cushions 19 inflated, the patient's body can be ensured to always remain balanced and stable, effectively avoiding body tilt or discomfort caused by weakened unilateral support force, and providing patients with continuous and reliable stability protection. Similarly, the first leg air cushion 12 and the second leg air cushion 13 can be inflated and deflated by the first air pump 17 to achieve massage of the patient's legs, thereby reducing the pressure on the patient's legs and further improving the comfort of the patient lying on the bed 1.

[0031] When the doctor examines the patient's abdominal wound, if the patient's wound is located on the front of the abdomen, the patient needs to lie flat. At this time, the electric telescopic rod 36 can be controlled to slightly move down the output end of the electric telescopic rod 36, that is, the chest restraint belt 3 and the hip restraint belt 4 are moved down at the contact point with the corresponding first roller 35, thereby increasing the pressure on the patient's shoulders and hips, and at the same time slightly increasing the inflation amount of the waist air cushion 6, thereby appropriately increasing the support force of the waist air cushion 6 for the patient's waist. This is because the patient needs to maintain a specific posture for a long time during wound observation, which increases the burden on the waist. Appropriately increasing the waist support force can effectively disperse this pressure and reduce the tension of the waist muscles, thereby relieving the fatigue and discomfort caused by maintaining the same posture for a long time, reducing the wound pulling pain or examination interruption caused by changes in body position, thereby improving the patient's comfort while ensuring the smooth progress of the doctor's observation work.

[0032] If the patient's wound is on the abdominal side wall, in order to facilitate the doctor to observe the wound, the patient needs to change his posture to a side-lying position. Before the patient turns over, it is necessary to ensure that the ankle restraint belt 9 on the second foot restraint belt 10 is located close to the direction in which the patient turns over, and the ankle restraint belt 9 on the first foot restraint belt 8 is located close to the direction of the patient's abdominal wound when the patient lies flat (the direction of the patient's abdominal wound when the patient lies flat is opposite to the direction in which the patient turns over). If the position is correct, there is no need to perform any operation on the ankle restraint belt 9. If the position is incorrect, it is necessary to remove the ankle restraint belt 9 on the patient's foot, and adjust the positions of the two ankle restraint belts 9 on the first foot restraint belt 8 and the second foot restraint belt 10 through two sliders according to the patient's turning direction.

[0033] After the ankle restraint belt 9 is in the correct position, the third electromagnet 46 is started to absorb the second sliding block 45 (the second sliding block 45 is made of magnetic material), that is, the second fixed block 48 is connected to the second sliding block 45, and then the third motor 30 is started to rotate the first screw rod 16, so that the second sliding block 45 and the second fixed block 48 connected to the second sliding block 45 move, and then the first leg air cushion 12 and the second leg air cushion 13 on the two first support plates 14 move synchronously. This synchronous movement can achieve a small movement of the patient's lower limbs, so that the relative position of the patient's upper and lower limbs is correct, which helps the patient to better cooperate with the doctor in turning over, and can also avoid the problem of spinal twisting or overextension caused by incorrect lower limb posture when the patient turns over, thereby ensuring the safety of the patient during the turning process.

[0034] Subsequently, the electric valve 23 corresponding to the first air pump 17 is controlled to increase the inflation volume of the second leg air cushion 13, the patient's legs are slightly lifted, and then the third electromagnet 46 corresponding to the position of the second leg air cushion 13 is closed, and then the third motor 30 corresponding to the first leg air cushion 12 is controlled to make the first leg air cushion 12 and the second airbag 11 connected thereto move toward the direction of the abdominal wound when the patient is lying flat, until the second airbag 11 presses against the leg corresponding to the direction in which the patient needs to turn over (for example, if he needs to turn over to the right, it presses against the patient's right leg), thereby effectively fixing the patient's position and providing support, avoiding the risk of injury caused by body imbalance or slipping due to turning over, and further ensuring the safety of the patient during turning over. After the second airbag 11 is moved, the inflation volume of the second leg air cushion 13 is reduced until the height of the second leg air cushion 13 is consistent with the height of the first leg air cushion 12.

[0035] After completing the above operations, the second motor 29 on both sides of the bed 1 is controlled to make the winding roller 39 on the side in the same direction as the patient's turning over reel in, and the winding roller 39 on the side opposite to the patient's turning over unwind, so that the chest restraint belt 3 and the hip restraint belt 4 are used to drive the patient's chest and hips to turn the patient over. By driving the chest and hips to turn over, direct pressure on the abdomen can be avoided, thereby reducing the stimulation and compression of abdominal wounds or injured parts due to the turning action. In addition, driving the chest and hips at the same time can help stabilize the spine and pelvis during the turning process, reduce spinal twisting or pelvic displacement caused by the turning action, which is particularly important for patients with abdominal injuries, and can effectively avoid secondary injuries that may be caused by changes in body position, and effectively improve the safety of patients during the turning process.

[0036] When the patient first turns over, the first roller 35 can be raised by controlling the electric telescopic rod 36 on the side in the same direction as the patient's turning over, so that the patient's shoulders and hips are subjected to an upward oblique force, thereby making it easier to drive the patient's body to turn over. As the turning over continues, the height of the above-mentioned first roller 35 can be gradually reduced to increase the horizontal component of force, thereby increasing the rotational torque and ensuring the stability of the turn. When the chest restraint belt 3 and the hip restraint belt 4 drive the patient's chest and hips to turn over, the waist air cushion 6 and the back air cushion 19 on the side opposite to the patient's turning direction are inflated by the second air pump 41. This can not only support the patient's waist and back when turning over, reduce the twisting and displacement of the spine during the turning process, but also disperse the pressure of the body on the bed surface during the subsequent doctor's examination, avoid long-term pressure on local tissues, and prevent the formation of pressure sores.

[0037] In addition, after the patient turns over (at this time the patient's turning angle is relatively small, and the magnet 47 on the limiting belt 32 does not contact the first electromagnet 33 on the abdominal restraint belt 5), the ankle restraint belt 9 can be moved on the first foot restraint belt 8 through the slider, so that the leg originally located on the opposite side of the patient's turning direction can be placed on the first airbag 7 and the second airbag 11 on the same side as the patient's turning direction through the movement of the slider, effectively dispersing the pressure of the legs on the bed surface and avoiding long-term pressure on local tissues, thereby effectively improving the safety and comfort of the patient after turning over. Since the first elastic belt connected to the wrist restraint belt 24 is elastic and has a certain length, the arm located on the opposite side of the patient's turning direction can move with the turning action.

[0038] When the patient is restrained normally, he can turn over slightly without touching the wound. However, when the patient is emotionally excited or suffers from rage, his body movements may become difficult to control, which may cause the angle of his turning over to exceed the limit. At this time, the magnet 47 on the limiting belt 32 will contact the first electromagnet 33 on the abdominal restraint belt 5 (the first electromagnet 33 is always in the on state), so that the limiting belt 32 is sucked by the first electromagnet 33 under the action of the magnet 47 thereon and quickly forms an effective restriction on the patient to prevent him from continuing to turn over, thereby ensuring the safety of the patient. At the same time, since the position of the pressure sensor 34 on the first electromagnet 33 corresponds to the position of the limiting belt 32, when the limiting belt 32 contacts and is adsorbed by the first electromagnet 33, the pressure sensor 34 will be subjected to pressure and send an electrical signal, and the second motor 29 is controlled by the electrical signal, so that the winding roller 39 on the side opposite to the patient's turning over direction begins to slowly wind up, thereby driving the patient's body to be pulled in the opposite direction of the patient's turning over through the chest restraint belt 3 and the hip restraint belt 4, so that the patient gradually returns to a lying position.

[0039] When the pressure value received by the pressure sensor 34 decreases to a certain level, the first electromagnet 33 will be turned off and the electromagnet 33 will stop adsorbing the magnet 47 on the limiting belt 32, thereby effectively avoiding unnecessary damage to the patient due to the adsorption force between the limiting belt 32 and the abdominal restraint belt 5 when the patient is not completely lying down. In addition, since the third airbags 20 located on both sides of the bed 1 are higher than the height of the waist air cushion 6 and the back air cushion 19, and the first airbags 7 and the second airbags 11 located on both sides of the bed 1 are higher than the height of the first leg air cushion 12 and the second leg air cushion 13, when the patient lies flat on the bed 1, the above-mentioned airbags can not only flexibly limit the patient to effectively prevent accidents such as the patient falling out of bed, but also enable the patient to move within a small range when being restrained (when the patient tries to move, the airbag can slightly deform with the patient's movements, thereby allowing the patient to move within a certain range).

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
