[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figures 1-9 As shown, a restraint and fixation device for the safe transportation of patients with craniocerebral trauma in the field comprises a main plate 1 and a lifting rod 3 penetrating the main plate 1, and a side plate 2 configured to be flipped toward the center of the main plate 1;

[0035] The fixed seat 5 is fixedly arranged on the main plate 1 and used for the activity of the side plate 2;

[0036] The rotating member 25 is synchronously active with the main plate 1;

[0037] The left sliding member 52 and the right sliding member 53 are slidingly arranged on the fixed seat 5 and symmetrically abutted with the rotating member 25, and the left sliding member 52 and the right sliding member 53 are symmetrically abutted with the rotating member 25 to form a slope groove for the oblique sliding of the side plate 2;

[0038] The slope groove has a low point and an opposite high point for the side plate 2 and the main plate 1 to be in the same horizontal plane.

[0039] Specifically, the rotating member 25 is fixedly arranged with the first abutting rod 251 and the second abutting rod 252 abutting with the left sliding member 52 and the right sliding member 53 respectively, further comprising a fixed gear 22 fixedly arranged on the side plate 2, and a driving gear 23 rotatably arranged on the fixed seat 5 and in mesh transmission with the fixed gear 22, and the tooth number ratio of the driving gear 23 and the fixed gear 22 is 2:1, when the side plate 2 drives the fixed gear 22 to rotate 180°, the driving gear 23 will rotate 90° relative to the fixed seat 5.

[0040] Further, the left sliding member 52 and the right sliding member 53 are in close contact and form a circular groove 56 for accommodating the rotating member 25 in the default state, the rotating side plate 2, the rotating member 25 is slidingly arranged on the driving gear 23 along the axial direction and rotates with the driving gear 23, when the patient needs to be transported in a side lying position, the back of the patient can be fixed by turning up the side plate 2, and the connection of the fixing belt 4 bound on the side plate 2 makes the patient be limited between the two side plates 2 when lying on the side. When the side plate 2 is rotated to 180°, the first abutting rod 251 and the second abutting rod 252 abut the left sliding member 52 and the right sliding member 53 respectively, so that the distance between the left sliding member 52 and the right sliding member 53 increases to accommodate the rotating member 25, at this time, the left sliding member 52 and the right sliding member 53 form a slope groove, and the side plate 2 is pulled away from the main plate 1, the side plate 2 slides along the slope groove from the high point to the low point, at this time, the side plate 2 and the main plate 1 are in the same horizontal plane, and the patient lying on the back can use it. And in the default state, the two side plates 2 are parallel and close to the main plate 1, the side plate 2 and the main plate 1 do not extrude each other, and the rotating angle is flexible, while the traditional hinged way will produce stress concentration area at the connection part of the side plate 2 and the main plate 1, which is easy to produce physical fatigue after long time use.

[0041] In the above technology, the side plate 2 can be turned up to fix the back of the patient, so that the patient can be transported in a side lying position, while the side plate 2 and the main plate 1 are in the same horizontal plane for the patient lying on the back to use, and compared with the traditional hinged way, it is less likely to produce stress concentration area and avoid physical fatigue.

[0042] As a further provided embodiment of the present application, the left slide 52 and the right slide 53 are provided with a second spring 54 for approaching the rotating member 25.

[0043] Specifically, the fixed seat 5 is provided with a sliding groove 51, the left slide 52 and the right slide 53 are slidingly arranged along the width direction of the sliding groove 51, and the second spring 54 is arranged on the inner wall of the sliding groove 51 and pushes the left slide 52 and the right slide 53 to approach each other. During the rotation of the rotating member 25, the first abutting rod 251 and the second abutting rod 252 are respectively extruded by the left slide 52 and the right slide 53 to form a damping force, so that the rotation of the side plate 2 is limited by the damping force and can hover at any angle, meeting the actual needs of different patients.

[0044] As a further provided embodiment of the present application, the left slide 52 is provided with a left locking groove 522 for retaining the rotating member 25, and the left locking groove 522 further includes a left guide surface 521 for guiding the coupling or decoupling of the rotating member 25.

[0045] Specifically, the left slide 52 is further provided with a left inclined groove 523 along the length direction, the first abutting rod 251 is in a default state in the left locking groove 522, the first abutting rod 251 is provided with an elastic member, during the rotation of the rotating member 25, the first abutting rod 251 slides out of the left locking groove 522 along the left guide surface 521, the coupling is completed, and the force generated by the first abutting rod 251 on the left guide surface 521 drives the left slide 52 to slide. Under the joint action of the two actions, the elastic member enters the left inclined groove 523 and is released under the elastic force of itself. The elastic member is inserted into the left inclined groove 523, and slides along the inclined groove while the rotating member 25 slides, so that the sliding track of the rotating member 25 and the side plate 2 is relatively stable. When the side plate 2 moves to the low point, the elastic member slides out of the slot 524 formed at the end of the left inclined groove 523.

[0046] Further, when the side plate 2 is stored, the side plate 2 is rotated to drive the rotating member 25 to rotate synchronously, at this time, the first abutting rod 251 automatically slides into the left locking groove 522 along the left guide surface 521.

[0047] As a further provided embodiment of the present application, the right slide 53 is provided with a right locking groove 532 for retaining the rotating member 25, and the right locking groove 532 further includes a right guide surface 531 for guiding the coupling or decoupling of the rotating member 25.

[0048] Specifically, the second abutting rod 252 does not abut against the right slider 53 in the default state, and the second abutting rod 252 is provided with an elastic member. The rotating of the rotating member 25 drives the second abutting rod 252 to slide along the right guide surface 531 into the right locking groove 532, and the end of the right inclined groove 533 opened along the length direction of the right slider 53 is located in the right locking groove 532, the second abutting rod 252 is limited by the arc structure of the right locking groove 532 to stop rotating, the maximum rotating angle of the opposite side plate 2 is limited, and stress damage of the rotating shaft of the opposite side plate 2 is avoided. At this time, a larger force is needed to pull the side plate 2 to make the second abutting rod 252 separate from the right locking groove 532, and then the elastic member corresponds to the right inclined groove 533 and slides.

[0049] As further provided in another embodiment of the application, the rotating member 25 is provided with a tapered portion 253 for clamping the left slider 52 / right slider 53 at the low point.

[0050] Specifically, the driving gear 23 is provided with a first spring 24 for pulling the rotating member 25. During the sliding of the rotating member 25 along the inclined groove, the narrow end of the tapered portion 253 always abuts against the left slider 52 or the right slider 53, and the end of the left slider 52 and the right slider 53 close to the low point is provided with an inclined surface 55. When the rotating member 25 slides to the inclined surface 55, the narrow end is pulled to slide along the inclined surface 55 by the first spring 24, and the displacement in the axial direction occurs, then the tapered portion 253 is decoupled from the left slider 52 and the right slider 53, and the tapered portion 253 is tightly attached to the inclined surface 55, and the inclined surface 55 is clamped in the gap between the tapered portion 253 and the driving gear 23, so that the rotating member 25 is clamped at the low point, and the main plate 1 and the side plate 2 are stably arranged on the same horizontal plane.

[0051] As further provided in another embodiment of the application, a main beam frame 11 arranged on the main plate 1 is further included, which is used for supporting the side plate 2 at the low point.

[0052] Specifically, the two ends of the main beam frame 11 extend out of the two sides of the main plate 1, and the side plate 2 is moved to the low point after being turned over, at this time, the bottom surface of the side plate 2 abuts against the top surface of the main beam frame 11, so that the side plate 2 is supported by the main beam frame 11. And the lifting rod 3 is fixedly arranged on the main beam frame 11, and the side plate 2 does not interfere with the normal use of the main beam frame 11 and the lifting rod 3 during the turning over and standing up of the side plate 2.

[0053] As further provided in another embodiment of the application, the side plate 2 is provided with a side beam frame 21 corresponding to the main beam frame 11, and a pin rod 28 extending to the main beam frame 11 is slidingly arranged on the side beam frame 21.

[0054] Specifically, when the side plate 2 is flipped and moved to the low point, the side beam frame 21 is overlapped with the main beam frame 11, and the adjacent surfaces of the side beam frame 21 and the main beam frame 11 are in an inclined state, the main beam frame 11 is in a structure of being narrow at the top and wide at the bottom, and the stability is stronger. At this time, the pin rod 28 can be manually slid to extend the pin rod 28 to the side of the main beam frame 11, or an electric telescopic rod is arranged to insert the pin rod 28 into the main beam frame 11, or other technical solutions known to those skilled in the art.

[0055] As further provided in another embodiment of the application, a stop rod 26 is arranged in cooperation with the pin rod 28, and the rotating piece 25 is axially movable and pushes against the stop rod 26 in the decoupling state.

[0056] Specifically, the third spring 27 is arranged on the pin rod 28 to extend the pin rod 28 outward, and the inclined block 16 is arranged on the main beam frame 11 to push the pin rod 28. When the rotating piece 25 slides to the inclined surface 55, the narrow end is pulled by the first spring 24 to slide along the inclined surface 55, and the displacement in the axial direction occurs, and then the conical part 253 is decoupled with the left sliding piece 52 and the right sliding piece 53. When the rotating piece 25 is displaced in the axial direction, the stop rod 26 is synchronously slid, the stop rod 26 no longer blocks the pin rod 28, the pin rod 28 is automatically extended to the main beam frame 11 by the pushing of the third spring 27, and no other driving source is needed, which is relatively simple. When it is needed to restore the side plate 2 to the default state, the inclined block 16 is first pressed to slide the pin rod 28 out of the main beam frame 11, and then the side plate 2 is slid along the inclined groove.

[0057] As further provided in another embodiment of the application, the movable plate 12 is movably arranged in the main plate 1, and the turning plates 13 are symmetrically arranged on both sides of the movable plate 12 to fix the head of the patient.

[0058] Specifically, the movable slot 14 is arranged on the main plate 1, and the stop blocks 15 are symmetrically arranged in the movable slot 14 to guide the deflection of the turning plates 13. The movable plate 12 is vertically arranged in the movable slot 14, and the included angle between the movable plate 12 and the turning plates 13 is 180° in the default state. At this time, the movable plate 12 and the turning plates 13 are flush with the main plate 1, the side plate 2 is tightly attached to the main plate 1, and the movable plate 12 is located in the movable slot 14, which does not affect the storage of the side plate 2. When the head of the patient is placed on the movable plate 12, the movable plate 12 is lowered under the action of gravity, the turning plates 13 are deflected to the center by the stop blocks 15, and the turning plates 13 clamp the head of the patient from both sides to avoid the movement of the head of the patient during the transfer.

[0059] As further provided in another embodiment of the application, the inflatable bags are arranged on the movable plate 12 and the turning plates 13.

[0060] Specifically, it further comprises an air pump for inflating the air bag, which can be an electric air pump or a squeeze air bag. After the flap 13 clamps the patient's head, the air pump inflates the air bag, causing the air bag to expand and further surround the patient's head. The elastic band fixed on the flap 13 fixes the patient's head, which can effectively prevent the patient's head from being injured again due to the vibration generated during the transfer process.

[0061] Working principle: when the patient needs to be transferred in a side-lying position, the side plate 2 can be turned up to fix the patient's back. The connection through the fixing belt 4 bound to the side plate 2 makes the patient be limited between the two side plates 2 when lying on the side. The first and second resistance rods 251 and 252 are respectively pressed by the left and right sliders 52 and 53 to form a damping force, so that the rotation of the side plate 2 is limited by the damping force and can hover at any angle.

[0062] When the side plate 2 is rotated to 180°, the first and second resistance rods 251 and 252 respectively support the left and right sliders 52 and 53, so that the distance between the left and right sliders 52 and 53 increases to accommodate the rotating piece 25. At this time, the left and right sliders 52 and 53 form an inclined slot, and the side plate 2 is pulled away from the main plate 1. The side plate 2 slides along the inclined slot from the high point to the low point, and at this time the side plate 2 is located on the same horizontal plane as the main plate 1.

[0063] When a patient who needs to lie flat is needed, continue to rotate the side plate 2 to 180°, and when the rotating piece 25 slides to the inclined surface 55, the narrow end is pulled by the first spring 24 to slide along the inclined surface 55, resulting in displacement in the axial direction. Subsequently, the tapered portion 253 is decoupled from the left and right sliders 52 and 53, and the tapered portion 253 is in close contact with the inclined surface 55, and the inclined surface 55 is clamped in the gap between the tapered portion 253 and the drive gear 23, so that the rotating piece 25 is clamped at the low point. When the rotating piece 25 displaces in the axial direction, the stop rod 26 slides synchronously, and the stop rod 26 no longer blocks the pin rod 28. The pin rod 28 is automatically extended towards the main beam frame 11 by the third spring 27, and the main beam frame 11 and the side beam frame 21 are assembled into one body by the pin rod 28, so that the structure of the main plate 1 and the side plate 2 is more stable when they are on the same horizontal plane.

[0064] When the patient's head is placed on the movable plate 12, the movable plate 12 is moved downward under the action of gravity, causing the flap 13 to be blocked by the stop block 15 and deflecting towards the center. The flap 13 clamps the patient's head from both sides, and the air pump inflates the air bag, causing the air bag to expand and further surround the patient's head. The elastic band fixed on the flap 13 fixes the patient's head, which can effectively prevent the patient's head from being injured again due to the vibration generated during the transfer process.

[0065] The foregoing merely illustrates some exemplary embodiments of the application, and it will be appreciated that those skilled in the art will be able to devise various modifications without departing from the spirit and scope of the application. The appended drawings and description are illustrative only, and are not intended to be limiting.
