[0001] The invention relates to the technical field of medical instruments, in particular to a nursing aid with a posture restraint adjustment function. Background Art

[0002] Medical devices refer to instruments, equipment or appliances that are used directly or indirectly on the human body. There are also many medical devices in psychiatry, because mental illness is a mental disorder caused by severe brain dysfunction. When mentally ill patients have an attack, they will show symptoms such as incoherent speech, violent struggles, and frantic dancing of their hands and feet. Therefore, nursing aids are needed to fix the position of mentally ill patients to prevent them from hurting others or injuring themselves due to struggling.

[0003] The existing patent (publication number: CN106726083A) discloses an auxiliary device for psychiatric nursing, including a base plate, support legs are provided at the four corners of the lower surface of the base plate, rail grooves are provided on both sides of the base plate, sliders are provided inside the rail grooves, guide rods and lead screws are provided in the rail grooves, the lead screws are connected to the sliders through a threaded pair, the end of the lead screws passes through the side of the base plate and is connected to the servo motor, the servo motor is fixed to the side of the base plate, and the guide rods pass through the through holes on the sliders and are slidably connected to the sliders, support plates are provided on the sliders, and first brackets are provided on the corresponding end surfaces of the support plates. The device can restrain and massage patients, and multiple restraint structures cooperate to have a good effect of restraining patients and prevent patients from being injured. The massage device can promote blood circulation of patients and accelerate the recovery process. A medicated pillow is placed, which helps to calm patients and is beneficial for nursing staff to treat and care for patients. The above technology has the following problems: 1. When the existing psychiatric nursing auxiliary device fixes the elbow of the psychiatric patient with an adhesive tape, it is necessary to wrap the adhesive tape around the patient's arm for a week and then lock the adhesive tape with a buckle. However, in actual use, the limbs of the psychiatric patient will be in a swinging state, and since the thickness of the limbs of different patients is different, and the length of the adhesive tape is fixed, it is difficult to fix; 2. Some psychiatric nursing auxiliary devices also use restraints to bind the torso and limbs of the psychiatric patient to the device, but in this fixing method, there will be gaps on both sides of the patient, that is, the restraints cannot be close to the patient, resulting in space for the psychiatric patient to struggle, and the patient's limbs will also be injured due to friction between the restraints and the gaps between the limbs and the restraints when the patient struggles; 3.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 15The present invention provides a technical solution: a nursing aid with a body position restraint adjustment function, comprising a body 1, a body position adjustment component 2 is arranged on the inner side of the body 1, a strip groove 3 and an arc groove 4 are respectively opened on the top surface of the body 1, a restraint component 5 is arranged in the middle of the strip groove 3 and the arc groove 4, a protection component 6 is arranged in the middle of the restraint component 5, and a headrest 7 is fixedly connected to one end of the top surface of the body 1; an adjustment port is opened on one side of the body 1 so that the nursing staff can reach into the body 1 to unlock the restraint component 5 that fixes the upper body of the mentally ill patient.

[0038] In this embodiment, Figure 1 , Figure 5-10 and Fig.13As shown, the constraint component 5 includes a mounting frame 501 fixedly connected to the top of the body position adjustment component 2, two fixing plates 502 are fixedly connected between the inner walls of the mounting frame 501, and straight grooves 503 are provided in the middle of the two fixing plates 502. A trigger block 504 is slidably connected between the two fixing plates 502, and T-shaped limit grooves 505 are provided on both sides of the trigger block 504 that are in contact with the mounting frame 501. T-shaped limit blocks 506 are slidably connected inside the T-shaped limit grooves 505. Two groups of inclined grooves 507 are provided on both sides of the trigger block 504 that are in contact with the two fixing plates 502, and the insides of the two groups of inclined grooves 507 are slidably connected to drive The driving pin 508 runs through the middle of the spiral groove 509, and the spiral groove 509 is provided on the outer surface of the cylindrical tube 5010. The two ends of the cylindrical tube 5010 are integrally formed with a rotating shaft 5026. The cylindrical tube 5010 is divided into a main tube 5010a and a secondary tube 5010b. The outer surface of the main tube 5010a is provided with two outer clamping claws 5011, and the outer surface of the secondary tube 5010b is provided with an inner clamping claw 5012. The end of the driving pin 508 away from the trigger block 504 is fixedly connected with a pull rope 5014. The top surface of the trigger block 504 is fixedly connected with two springs 5024. The tops of the two springs 5024 are fixed between them. A pressure plate 5025 is connected, a vertical connecting rod 5027 is fixedly connected to the middle of the bottom surface of the trigger block 504, and a handle 5028 is fixedly connected to the bottom end of the vertical connecting rod 5027; when in use, the limbs of the mentally ill patient are directly pressed down between the inner clamping claw 5012 and the outer clamping claw 5011, and the patient's limbs are used to press the pressure plate 5025 downward to drive the spring 2 5024 and the trigger block 504 to move downward. When the trigger block 504 moves downward, it will drive the driving pin 508 to approach the two walls of the installation frame 501 through the inclined groove 507. At the same time, the driving pin 508 will be close to the arc cavity 5013 due to the inclination of the bottom of the inclined groove 507. When the driving pin 508 moves, it will drive the main cylinder 5010a and the sub-cylinder 5010b to rotate around the rotating shaft 5026 through the spiral groove 509, thereby driving the respectively connected jaws to rotate, thereby realizing the opening and closing of the inner jaw 5012 and the outer jaw 5011. This structure can realize the rapid fixation of the limbs of the mentally ill patient. The limbs of the mentally ill patient only need to be pressed down between the two sets of jaws to automatically close the inner jaw 5012 and the outer jaw 5011. There is no need to perform a series of cumbersome operations such as wrapping the limbs of the mentally ill patient, which greatly reduces the difficulty of fixing the mentally ill patient.

[0039] In this embodiment, Fig.11As shown, the two outer clamping jaws 5011 are provided with arc-shaped cavities 5013 inside, and receiving ports 5015 are equiangularly distributed on one side of the arc-shaped cavity 5013, and the inner wall of the receiving port 5015 is fixedly connected with a connecting plate 5016, and a spring 1 5017 is fixedly connected to the side of the connecting plate 5016 close to the receiving port 5015, and a movable check block 5018 is fixedly connected to the end of the spring 1 5017 away from the connecting plate 5016, and a guide sleeve 5019 is fixedly connected to the side of the connecting plate 5016 away from the receiving port 5015; the fixed check block 5023 and the movable check block 5018 are both curved surfaces close to the outer side of the outer clamping jaw 5011, and the surface of the curved surface smoothly transitions from low to high. When the inner clamping jaw 5012 and the outer clamping jaw 5011 are closed, the fixed check block 5023 and the movable check block 5018 are both curved surfaces. The surface of the curved surface smoothly transitions from low to high. When the inner clamping jaw 5012 and the outer clamping jaw 5011 are closed, the fixed check block 5023 and the movable check block 5018 are both curved surfaces. The fixed check block 5023 contacts the lowest point of the curved surface of the movable check block 5018, and the fixed check block 5023 will squeeze the movable check block 5018 into the receiving port 5015 until the fixed check block 5023 passes the movable check block 5018, and then the movable check block 5018 pops out from the receiving port 5015 again under the action of spring 1 5017. Conversely, when the inner jaw 5012 and the outer jaw 5011 are opened, the side wall of the curved surface of the fixed check block 5023 and the side wall of the curved surface of the movable check block 5018 are in direct contact at this time, making it impossible for the fixed check block 5023 to squeeze the movable check block 5018 into the receiving port 5015, thereby locking the two sets of jaws and preventing the jaws from opening due to the struggle of the mentally ill patient.

[0040] In this embodiment, Figure 10-15As shown, the pull rope 5014 is composed of a main rope 5014a and a plurality of auxiliary ropes 5014b, and the plurality of auxiliary ropes 5014b are equidistantly distributed on the outer surface of the main rope 5014a. The main rope 5014a runs through the middle of the guide sleeve 5019, and one end of the auxiliary rope 5014b away from the main rope 5014a is connected to one side of the movable check block 5018. The number of spiral grooves 509 on the outer surface of the main cylinder 5010a and the auxiliary cylinder 5010b are both two, and the two spiral grooves 509 are symmetrically distributed about the center line of the cylinder body. An annular groove 5020 is opened in the middle of the main cylinder 5010a, and a T-shaped rope 5021 runs through the middle of the annular groove 5020. One end of the T-shaped rope 5021 extending to the outside of the main cylinder 5010a is fixedly connected to a spherical hollow frame, and the T-shaped rope 50 21 extends to the two ends of the main tube 5010a and is fixedly connected with a pulling ring 5022, and the pulling ring 5022 is sleeved on the outer surface of the main rope 5014a; the diameter of the spherical hollow frame is greater than the width of the annular groove 5020, so that the spherical hollow frame is always kept on the outside of the main tube 5010a. When it is necessary to release the restraint on the mentally ill patient, the spherical hollow frame must be pulled first to drive the T-shaped rope 5021 and the pulling ring 5022 to move, and the main rope 5014a is pulled by the pulling ring 5022, and the main rope 5014a is pulled by the auxiliary rope 5014b to move the movable check block 5018 into the storage port 5015, so that the movable check block 5018 and the fixed check block 5023 are disengaged, and the lock of the inner jaw 5012 and the outer jaw 5011 is released, so as to open it.

[0041] In this embodiment, Figure 6 and Fig.10 As shown, a plurality of fixed check blocks 5023 are provided on both sides of the inner jaw 5012, and the inner jaw 5012 is located in the center of the secondary cylinder 5010b, and the width of the inner jaw 5012 is smaller than the distance between the two outer jaws 5011; when the inner jaw 5012 and the outer jaw 5011 cooperate with each other to fix and restrain the limbs or torso of the mentally ill patient, the inner jaw 5012 can enter into the gap between the two outer jaws 5011, and this structure can improve the application range of the jaws and fix the mentally ill patients with thin stature.

[0042] In this embodiment, Figure 7 and Fig. 9As shown, an annular limiting groove 507a is provided on the inner wall of the inclined groove 507, and an elliptical piece 508a is integrally formed at the end of the driving pin 508, and the elliptical piece 508a is slidably arranged inside the annular limiting groove 507a, and the driving pin 508 passes through the middle of the straight groove 503, and there is a height difference between the two ends of the inner bottom of the inclined groove 507; the closer the inner bottom of the inclined groove 507 is to the edge of the trigger block 504, the shallower the depth of the inclined groove 507, and conversely, the closer the inner bottom of the inclined groove 507 is to the middle of the trigger block 504, the deeper the depth, and the elliptical piece 508a can prevent the driving pin 508 from rotating around its own axis, thereby preventing the pull rope 5014 from being twisted and shortened due to the rotation of the driving pin 508, causing the movable check block 5018 to be always in a pulled state and unable to extend normally from the storage opening 5015 to connect with the fixed check block 5023 When the trigger block 504 moves downward, the driving pin 508 will move along the straight groove 503 toward the edge of the trigger block 504 through the cooperation of the inclined groove 507 and the straight groove 503. When the driving pin 508 moves, it will drive the outer clamp 5011 and the inner clamp 5012 to approach each other through the spiral groove 509 to restrain and fix the limbs of the mentally ill patient. In addition, in the process of the driving pin 508 moving along the straight groove 503, the end of the driving pin 508 will also approach the arc cavity 5013, so that the main rope 5014a changes from a stretched state to a loose state. At this time, the spring 5017 rebounds and releases the movable check block 5018 from the storage port 5015, so that the movable check block 5018 and the fixed check block 5023 are in contact and locked, preventing the inner clamp 5012 and the outer clamp 5011 from being opened under the struggle of the mentally ill patient.

[0043] In this embodiment, Figure 8 As shown, the T-shaped limit block 506 is integrally formed on the inner wall surfaces on both sides of the installation frame 501, and the T-shaped limit groove 505 is located in the middle of the trigger block 504; the two ends of the T-shaped limit groove 505 are not connected to the upper and lower surfaces of the trigger block 504, so that the T-shaped limit block 506 can slide along the T-shaped limit groove 505 while limiting it, preventing the T-shaped limit block 506 from escaping from the T-shaped limit groove 505. This structure can limit the trigger block 504, so that the trigger block 504 is slidably set in the middle of the installation frame 501 and slides up and down.

[0044] In this embodiment, Figure 5 and Fig.11As shown, the protection component 6 includes a protection shell 601 fixedly connected between the bottom surfaces of the two fixed plates 502, and a total air bag 602 is arranged inside the protection shell 601. The two sides of the total air bag 602 are respectively connected with a single hose 603 and a three-way hose 604, and the ends of the single hose 603 and the three-way hose 604 away from the total air bag 602 are connected with an arc air bag 605, and the arc air bag 605 is arranged on the inner circle of the inner clamping jaw 5012 and the outer clamping jaw 5011; an avoidance hole is arranged in the middle of the total air bag 602, and the vertical connecting rod 5027 passes through the avoidance hole. When the trigger block 504 moves downward, while driving the two groups of clamping jaws to close, it also squeezes the total air bag 602, squeezes the air in the total air bag 602 into the arc air bag 605, and expands the arc air bag 605, so as to prevent the limbs of the mentally ill patient from being injured due to friction with the clamping jaws due to struggling, thereby playing a protective role.

[0045] In this embodiment, Figure 1-4 As shown, the body position adjustment component 2 includes a one-way screw 201 and a two-way screw 202 which are rotatably connected to the two side walls of the body 1. The one-way screw 201 runs through the middle of the slider 203. The slider 203 is fixedly connected to one end of the bottom surface of the U-shaped beam 204. The top surfaces of both ends of the U-shaped beam 204 extend to the outside of the top surface of the body 1 through the strip groove 3 and are connected to the installation frame 501. The middle part of the two-way screw 202 is threadedly connected to two guide frames 205. The middle parts of the two guide frames 205 are movably connected with a moving column 206. The top of the moving column 206 is connected to the bottom surface of the installation frame 501 through a bearing block. The bearing block is slidably arranged in the middle of the arc groove 4; the one-way screw 201 and the two-way screw 202 are located in the body 1 A rocker is provided at one end of the outer side, and the one-way screw 201 is located at one end inside the body 1 and is rotatably connected to one side of the mounting plate. The mounting plate is welded to the inner bottom of the body 1, and the one end of the bidirectional screw 202 is located inside the body 1 and is rotatably connected to one side of the inner wall of the body 1. When the body position of the mentally ill patient needs to be adjusted, the bidirectional screw 202 can be rotated to drive the two guide frames 205 to move in opposite directions. At this time, the supporting block will move along the arc groove 4 with the cooperation of the arc groove 4, the moving column 206 and the guide frame 205, thereby driving the constraint component 5 on the top surface of the supporting block to move, so as to adjust the body position of the mentally ill patient and control the opening or closing of the legs of the mentally ill patient for convenient care.

[0046] The use method and advantages of the present invention: When the nursing aid with posture restraint adjustment function is used, the working process is as follows:

[0047] First, the limbs of the mentally ill patient are pressed against the pressure plate 5025 in the restraint component 5. The pressure plate 5025 will drive the two sets of jaws to close by moving the trigger block 504 downward, thereby realizing rapid fixation of the limbs of the mentally ill patient. There is no need to wrap and tie the limbs of the mentally ill patient, which greatly reduces the difficulty of restraining the mentally ill patient. At the same time, during the downward movement of the trigger block 504, the total airbag 602 will be squeezed to expand the arc-shaped airbag 605, thereby separating the patient's limbs from the jaws to prevent the patient from being injured by friction with the jaws during the struggle. After the mentally ill patient is fixed, the body position of the mentally ill patient can be adjusted through the body position adjustment component 2, which is convenient for nursing staff to adjust the body position of the mentally ill patient according to needs for care.
