[0002] When medical staff treat people with fractures, after bandaging the corresponding wounds, they need to use splints to fix the injured part of the person, which is conducive to the recovery of the injured part. However, if the injured person moves inadvertently or others move the patient's limbs, it is easy to cause secondary injury to the patient.

[0003] The existing splint installation and fastening device, after the splint is fixed on the patient's limb, needs to fix the patient's limb splint part through the device, so as to avoid secondary injury caused by the movement of the patient's limb. When installing and fastening the splint on the limb part, multiple bolts are required to connect the two clamping blocks accordingly, so as to achieve the purpose of installing and fastening the splint on the limb, making it impossible for medical personnel to quickly install and fasten the splint, and increasing the time required for the operator to operate and fasten the splint; at the same time, due to the excessive hardness of the splint, it often forms pressure on the patient's limbs. When the patient's limbs are stretched, the patient's limb extension is limited due to the fastening and clamping, making the patient's limbs stiff, and even causing leg cramps.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] like Figure 1 , 2 As shown, a leg clamping and fixing device comprises a bottom plate 1, a rotating plate 2, a lifting bracket 3 and a leg rest 4; wherein:

[0029] A universal wheel 11 with a wheel brake is arranged at the bottom of the base plate 1. The base plate 1 can be arranged with a counterweight block of a certain weight, or a counterweight block can be loaded therein to prevent the device from easily tipping over.

[0030] The rotating plate 2 is rotatably mounted on the bottom plate 1 to rotate accordingly with the stretching of the legs, thereby preventing the legs from being locally stressed and squeezed.

[0031] The lifting bracket 3 is installed on the rotating plate 2 in a liftable manner to be adjusted according to the height and lying height of the patient.

[0032] The leg rest 4 is installed in the lifting bracket 3, and the leg rest 4 is provided with a leg rest ring 41 which can be inflated and deflated. The patient's legs are placed in the leg rest ring 41 to avoid a greater pressure when the legs are fixed; the leg rest ring 41 is provided with a first detection component for controlling the inflation and deflation of the leg rest ring 41, a second detection component for controlling the rotation of the rotating plate 2 and a third detection component for controlling the lifting bracket 3 to rise and fall, which are used to detect the state of the patient's legs in the leg rest ring 41, so that the control components are adjusted accordingly to keep the patient's legs in a good comfort level.

[0033] like Figure 2 , 3 As shown, the leg rest portion 4 also includes a first support plate 43 and a second support plate 44 which are symmetrically connected to the top and bottom surfaces of the leg rest ring 41. The first support plate 43 is connected to the inner top of the lifting bracket 3 through a pushing mechanism, and the second support plate 44 is connected to the inner bottom of the lifting bracket 3 through a rotating shaft 48.

[0034] Specifically, the leg rest ring 41 is connected to an air pump 49 for inflating or exhausting the leg rest ring 41, and the air pump 49 can be installed inside the lifting bracket 3; the leg rest ring 41 is made of a relatively hard shrinkable and deformable material, and its inner hollow is used for inflation to support the patient's legs. The first support plate 43 is controlled by a push mechanism to move up and down to squeeze the leg rest ring 41 in space and fix the legs, so that the leg rest ring 41 can adapt to the legs of patients of different thicknesses; because the leg rest ring 41 can shrink and deform to a certain extent, when the patient stretches his legs, a torsional force is applied to the side of the leg rest ring 41 and a torsional force is formed, so that the rotating shaft 48 rotates accordingly following the torsion of the leg rest ring 41.

[0035] like Figure 2 As shown, the pushing mechanism includes a first electric push rod 46 installed on the top of the lifting bracket 3, and the driving end of the first electric push rod 46 extends downward to the inside of the lifting bracket 3 and is connected to the top surface of the first support plate 43.

[0036] Exemplarily, a fixing seat 47 is provided on the top of the lifting bracket 3 , and the first electric push rod 46 is installed on the fixing seat 47 .

[0037] In one embodiment, the first detection member is a first pressure sensor installed on the inner bottom surface of the first support plate 43 , and the pressure value detected by the first detection member is used to control the inflation and deflation of the leg rest ring 41 and control the start and stop of the first electric push rod 46 .

[0038] Specifically, the air pump 49 , the first electric push rod 46 , and the first pressure sensor are all electrically connected to a controller 7 , and a high threshold value can be set for the first pressure sensor on the controller 7 .

[0039] After the patient's legs are placed in the leg rest ring 41, the air pump 49 is started to inflate the leg rest ring 41. At the same time, the first electric push rod 46 is started to move downward. When the first support plate 43 contacts the top surface of the leg rest ring 41 and forms an extrusion, the patient's legs are initially restricted in the leg rest ring 41. When the extrusion continues so that the pressure value detected by the first pressure sensor triggers a high threshold alarm, the controller 7 controls the air pump 49 and the first electric push rod 46 to stop running, so that the patient's legs are fixed.

[0040] In one embodiment, the second detection member is a torque sensor installed on the rotating shaft 48, and the torque value detected by the second detection member is used to control the rotating plate 2 to rotate accordingly.

[0041] Specifically, the torque sensor is electrically connected to the controller 7, and a high threshold and a low threshold can be set for the torque sensor on the controller 7. When the patient's legs are extended and rotated to a certain extent, the rotating shaft 48 will rotate to a certain extent and the torque values ​​in different directions will be detected by the torque sensor (the torque value detected by the forward rotation is set to be a positive value, and the torque value detected by the reverse rotation is set to be a negative value); when the detected torque value triggers a high threshold alarm, or triggers a low threshold alarm, the rotating plate 2 will be controlled to rotate in the opposite direction of the torsional force, so as to drive the leg rest ring 41 to rotate, so that the torsional force applied by the patient on the leg rest ring 41 gradually disappears.

[0042] In one embodiment, the first support plate 43 and the second support plate 44 are arc-shaped plates matching the outer side of the leg rest ring 41, and guide plates 45 for guiding their movement are disposed at corresponding ends of the first support plate 43 and the second support plate 44.

[0043] Exemplarily, one end of the guide plate 45 is connected to the end of the second support plate 44, and the end of the first support plate 43 corresponding to the end of the second support plate 44 is provided with a guide groove matching the guide plate 45, so that the other end of the guide plate 45 can move in the guide groove, thereby guiding the first support plate 43 to move up and down.

[0044] like Figure 3As shown, a driving motor 5 is disposed in the middle of the base plate 1 , and a driving end of the driving motor 5 is connected to the rotating plate 2 to control the rotating plate 2 to rotate.

[0045] The driving motor 5 is electrically connected to the controller 7. When the rotating plate 2 needs to be controlled to rotate, the controller 7 controls the start and rotation direction of the driving motor 5 according to the detection value of the torque sensor, thereby realizing the rotation of the rotating plate 2 in different directions.

[0046] In one embodiment, the contact surface of the bottom plate 1 and the rotating plate 2 is provided with a moving pair for guiding the rotation. Exemplarily, the moving pair is composed of an arc groove and an arc block, the arc groove is provided on the top surface of the bottom plate 1, and the arc block is provided on the bottom surface of the rotating plate 2; when the rotating plate 2 rotates, the arc block moves in the arc groove, so that the rotating plate 2 can rotate stably.

[0047] like Figure 1 As shown, fixed columns 21 are provided at both ends of the rotating plate 2, and the two bottom ends of the lifting bracket 3 are movably inserted into the two fixed columns 21 respectively. The fixed columns 21 are provided with second electric push rods that can be started and stopped synchronously, and the driving end of the second electric push rod is connected to the bottom end of the lifting bracket 3, so that the lifting bracket 3 can be controlled to move up and down.

[0048] In one embodiment, the third detection member is a second pressure sensor 42, and second pressure sensors 42 are provided at both ends of the inner bottom side of the leg rest ring 41. The pressure values ​​detected by the two second pressure sensors 42 are used to control the start and stop of the second electric push rod.

[0049] Specifically, the two second pressure sensors 42 and the two second electric push rods are electrically connected to the controller 7. The two second pressure sensors 42 can set high thresholds respectively on the controller 7, and when the pressure values ​​detected by them trigger the high threshold alarm, the controller 7 will control the two second electric push rods to start simultaneously.

[0050] After the patient's legs are placed in the leg rest ring 41, since the legs are not necessarily in a state parallel to the axial direction of the leg rest ring 41, the legs will form different forces at the front and rear ends of the inner bottom side of the leg rest ring 41. Among them, when the pressure value detected by the second pressure sensor 42 at the front end of the inner bottom side of the leg rest ring 41 triggers a high threshold alarm, it means that the patient's legs are in a downward tilted state, and the height of the leg rest ring 41 needs to be increased; when the pressure value detected by the second pressure sensor 42 at the rear end of the inner bottom side of the leg rest ring 41 triggers a high threshold alarm, it means that the patient's legs are in an upward tilted state, and the height of the leg rest ring 41 needs to be lowered, so that the controller 7 controls the two second electric push rods to rise or fall, so as to adjust the legs to be parallel to the axial direction of the leg rest ring 41, so that the legs are in a better fixed state.

[0051] It should be noted that the fixing device can be equipped with a plug for connecting to an external power supply, or a built-in rechargeable power supply 6. The controller 7 is connected to the power supply and controls the power supply of each electrical device. The lifting bracket 3 is provided with a power switch and manual switches for manually controlling the start and stop of the air pump 49, the first electric push rod 46, the second electric push rod, and the drive motor 5, as well as corresponding operating indicator lights (not shown in the figure); at the same time, the lifting bracket 3 is also provided with an automatic switch. After pressing the automatic switch, the controller 7 automatically controls the start and stop of the air pump 49, the first electric push rod 46, the second electric push rod, and the drive motor 5 according to the detection signal.

[0052] When in use, the fixing device is moved to the patient, and the height of the leg rest ring 41 is preliminarily adjusted according to the height of the patient lying; the patient's legs are placed in an appropriate position inside the leg rest ring 41, the air pump 49 is started to inflate the leg rest ring 41, and the first electric push rod 46 is started to restrict the leg rest ring 41, thereby fixing the patient's legs; the automatic switch is pressed, and the controller 7 will control the start and stop of the air pump 49, the first electric push rod 46, the second electric push rod, and the drive motor 5 according to the detection signals of the first pressure sensor, the second pressure sensor 42, and the torque sensor, so that the fixing device can be adjusted accordingly according to the patient's leg extension, ensuring that the patient's legs and the leg rest ring 41 are in an axially horizontal fixed state, avoiding local compression of the patient's legs by the leg rest ring 41, preventing the patient's limb stiffness, and even leg cramps.
