Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a limb fixing device for emergency patients. Background Art

[0002] After suffering trauma, emergency patients often need temporary fixation of the injured part to prevent further damage and relieve pain. Limb fixation devices play an important role in this process. They can help keep the fracture or other soft tissue injury site stable for initial diagnosis and treatment, and prepare for subsequent professional medical treatment (such as surgery).

[0003] In the early days, doctors used simple tools such as plaster and splints to immobilize patients' injured limbs. Although these methods are effective, they may not be flexible enough in some cases. As medical technology advances, more types of immobilization devices have emerged, including but not limited to adjustable plastic splints, inflatable immobilizers, and devices specifically designed for specific types of injuries. These new immobilization devices not only provide better stability, but are also more comfortable and can adapt to body parts of different shapes and sizes.

[0004] For emergency patients, in order to prevent secondary injuries, the injured limbs need to be fixed as quickly as possible, and some patients need a certain degree of joint movement to promote blood circulation and prevent muscle necrosis. However, most existing fixation devices are not effective in fixing the patient's limbs, and the fixed devices are immobile or difficult to adjust, and the joints of the limbs cannot move for a long time. Summary of the invention

[0005] In order to solve the above problems, the injured limbs of emergency patients can be quickly fixed and the patient's joints can maintain a certain degree of movement. The present invention proposes a limb fixation device for emergency patients, which fixes the limb to be fixed by cooperating with an adjustable fixing belt and a fixing plate, and is fixed to a bed or a stretcher by a support. After the limb is fixed, the joint can maintain a certain degree of movement through the joint bearing between the two fixing plates.

[0006] In order to achieve the technical objectives in the above content, the present invention is implemented by the following technical solutions: a limb fixation device for emergency patients, including a support;

[0007] The support is composed of an upper clamping plate and a lower clamping plate, a fixing column is installed on the front side of the top of the upper clamping plate, a front fixing plate is installed on the top of the fixing column, a circular ring is installed on the bottom of the front fixing plate and the circular ring is sleeved with the fixing column, the left and right sides of the front fixing plate are connected with symmetrical side fixing plates through fixing ropes, and two ladder buckles are installed on the outer side of the side fixing plate on the left side of the front fixing plate, and the ladder buckles are connected with fixing belts;

[0008] The rear end of the front fixing plate is connected to the rear fixing plate through a joint bearing, and the structure of the rear fixing plate is the same as that of the front fixing plate, and the rear fixing plate is installed with side fixing plates, ladder buckles, fixing belts, cross bars, disassembly and assembly plates and U-shaped buckles of the same structure in the same way. The difference between the rear fixing plate and the front fixing plate is that a card slot is provided on the outer side of the rear ends of the side fixing plates on the left and right sides of the front fixing plate, and a limiting connecting rod is hinged on the outer side of the front ends of the side fixing plates on the left and right sides of the rear fixing plate, and the front and rear side fixing plates are connected together by the limiting connecting rod, so that the joint bearing is locked when the limb is fixed, and after the limiting connecting rod is removed from the slot, the front fixing plate and the rear fixing plate can move around the joint bearing, thereby realizing that the joint can move to a certain extent after the limb is fixed.

[0009] Further, the spherical bearing comprises an outer ring end sleeve connected to the front fixing plate and an inner ring connecting rod connected to the rear fixing plate, and the inner ring connecting rod can rotate in multiple directions;

[0010] Furthermore, the other ends of the fixing belts are connected to a crossbar, a disassembly plate is installed in the middle of the crossbar, and the lower end of the disassembly plate is bent inward to form a U-shaped buckle;

[0011] Furthermore, a straight groove is provided on the lower side of the side fixing plate on the right side of the front fixing plate, and the straight groove is the same size as the U-shaped buckle. The limb can be fixed between the front fixing plate, the side fixing plate and the fixing belt by snapping the U-shaped buckle into the straight groove and adjusting the fixing belt through the ladder buckle;

[0012] Furthermore, a right-side sliding groove is provided on the top rear side of the upper clamping plate, and a plurality of equally spaced positioning threaded holes are horizontally provided on the upper clamping plate on the left side of the sliding groove;

[0013] Furthermore, a hinge plate is hinged at the front end of the slide slot, and the other end of the hinge plate can move in the slide slot, and a movable bolt is sleeved on the other end of the hinge plate, and the movable bolt can cooperate with the positioning threaded hole to fix the hinge plate, and the hinge plate can support the rear fixing plate to increase the stability of the device, and adjust the support height, thereby changing the angle at which the rear fixing plate can swing downward, so that the limb can move at a wider angle;

[0014] Furthermore, a vertical screw is installed at the bottom of the upper clamping plate, and a hole with a larger inner diameter corresponding to the screw is opened on the lower clamping plate. The lower clamping plate and the upper clamping plate can be tightened by adjusting the nut on the screw, so as to facilitate fixing the support on the bed or stretcher;

[0015] Furthermore, the upper surfaces of the front fixing plate and the rear fixing plate are both covered with silicone pads, and the inner sides of the side fixing plates are covered with the same silicone pads, which play a buffering role when fixing the patient's limbs and improve the patient's comfort;

[0016] Furthermore, the fixing belt passes through the ladder buckle and is adjustable, and the fixing belt can be tightened or loosened through the ladder buckle, so as to achieve a better fixing effect when fixing the limbs of different patients.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention can quickly fix the limbs of emergency patients. Before use, the support is first fixed to the side of the bed or stretcher. When fixing the limbs, the limbs are first placed on the front and rear fixing tables so that the limb joints correspond to the positions of the joint bearings. The U-shaped buckle is clamped in the straight groove and then the fixing belt at the ladder buckle is pulled to tighten it, and the tightness is adjusted as needed to fix the limbs;

[0019] 2. After the limb is fixed, the present invention can move the limit link out of the slot and utilize the rotation effect of the joint link to achieve a certain degree of movement at the limb joint. At the same time, by adjusting the support height of the hinge plate to the rear fixing plate, the patient can swing the movable joint upward and left and right as well as downward.

DETAILED DESCRIPTION

[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0029] Example 1

[0030] See also Figures 1 to 6 As shown, and according to the contents of this specification, a limb fixation device for emergency patients is proposed, comprising a support 1;

[0031] The support 1 is composed of an upper splint 101 and a lower splint 102. A fixing column 104 is installed on the front side of the top of the upper splint 101. A front fixing plate 2 is installed on the top of the fixing column 104. A circular ring 201 is installed at the bottom of the front fixing plate 2 and the circular ring 201 is sleeved with the fixing column 104. The left and right sides of the front fixing plate 2 are connected with symmetrical side fixing plates 5 through a fixing rope 4. Two ladder buckles 6 are installed on the outer side of the side fixing plate 5 on the left side of the front fixing plate 2. A fixing belt 7 is connected to the ladder buckle 6. The fixing belt 7 passes through the ladder buckle 6 and is adjustable. The fixing belt 7 can be tightened or loosened by the ladder buckle 6, so as to have a better fixing effect when fixing the limbs of different patients. The other ends are connected to a cross bar 8, and a disassembly plate 9 is installed in the middle of the cross bar 8. The lower end of the disassembly plate 9 is bent inward to form a U-shaped buckle 901. A straight groove 501 is opened on the lower side of the side fixing plate 5 located on the right side of the front fixing plate 2. The straight groove 501 is the same size as the U-shaped buckle 901. The limbs can be fixed between the front fixing plate 2, the side fixing plate 5 and the fixing belt 7 by clamping the U-shaped buckle 901 in the straight groove 501 and adjusting the fixing belt 7 through the ladder buckle 6. The upper surfaces of the front fixing plate 2 and the rear fixing plate 3 are both covered with a silicone pad 202, and the inner side of the side fixing plate 5 is covered with the same silicone pad 202, which plays a buffering role when fixing the patient's limbs and improves the patient's comfort.

[0032] The rear end of the front fixing plate 2 is connected to the rear fixing plate 3 through a joint bearing 10. The joint bearing 10 includes an outer ring end sleeve 1001 connected to the front fixing plate 2 and an inner ring connecting rod 1002 connected to the rear fixing plate 3. The inner ring connecting rod 1002 can rotate in multiple directions. The structure of the rear fixing plate 3 is the same as that of the front fixing plate 2. The side fixing plates 5, ladder buckles 6, fixing belts 7, cross bars 8, disassembly plates 9 and U-shaped buckles 901 of the same structure are installed on the rear fixing plate 3 in the same way. The difference between the rear fixing plate 3 and the front fixing plate 2 is that the side edges on the left and right sides of the front fixing plate 2 A slot 502 is provided on the outer side of the rear end of the fixing plate 5, and a limiting link 503 is hinged on the outer side of the front end of the side fixing plates 5 on the left and right sides of the rear fixing plate 3. The front end of the limiting link 503 is a protruding column and can be connected with the slot 502. The front and rear side fixing plates 5 are connected together through the limiting link 503, so that the joint bearing 10 is locked when the limb is fixed, and after the limiting link 503 is removed from the slot 502, the front fixing plate 2 and the rear fixing plate 3 can move around the joint bearing 10, so that the joint can move to a certain extent after the limb is fixed.

[0033] A vertical screw 103 is installed at the bottom of the upper splint 101, and a hole with a larger inner diameter corresponding to the screw 103 is opened on the lower splint 102. The lower splint 102 and the upper splint 101 can be tightened by the adjusting nut 105 on the screw 103, and circular grooves are opened on the two corresponding surfaces between the upper splint 101 and the lower splint 102, so that the support 1 can be fixed in a variety of positions, such as the edge of a bed or the side of a stretcher.

[0034] A slide groove 11 is provided on the right side of the top rear side of the upper splint 101, and a plurality of equidistant positioning threaded holes 1101 are horizontally provided on the upper splint 101 on the left side of the slide groove 11. A hinge plate 12 is hinged at the front end of the slide groove 11, and the other end of the hinge plate 12 can move in the slide groove 11, and a movable bolt 1201 is sleeved on the other end of the hinge plate 12. The movable bolt 1201 can cooperate with the positioning threaded hole 1101 to fix the hinge plate 12. The hinge plate 12 can support the rear fixed plate 3 to increase the stability of the device and adjust the support height, thereby changing the angle at which the rear fixed plate 3 can swing downward, so that the limbs can move at a greater angle.

[0035] When it is necessary to fix the limbs of the emergency patient, confirm that the limiting connecting rod 503 on the side fixing plate 5 is engaged with the card slot 502, and then the patient's limbs are placed on the front fixing plate 2 and the rear fixing plate 3 that have been fixed on the support 1, keep the joints of the patient's limbs corresponding to the joint bearings 10 of the device, and snap the U-shaped buckle 901 on the disassembly plate 9 into the straight groove 501 of the side fixing plate 5. At this time, the cross bar 8 on the disassembly plate 9 drives the fixing belt 7 to wrap around the patient's limbs, and then the fixing belt 7 is pulled from the ladder buckle 6 to tighten it to a suitable tightness according to the specific situation of the patient. When tightening, the side fixing plate 5 and the fixing rope 4 will be attached to both sides of the patient's limbs, and the patient's limbs will be fixed and protected through the front and rear fixing plates 3 and the side fixing plates 5.

[0036] When the patient needs to move the joints of the fixed limbs, he only needs to move the ends of the limit links 503 on the left and right sides out of the slots 502. The joint bearing 10 can move after losing the restrictions of the side fixing plates 5 and the limit links 503. At this time, the patient's limb joints can move to a certain extent, which promotes limb blood circulation and prevents necrosis. The bending height of the hinge plate 12 can be adjusted by adjusting the movable bolt 1201 and fixing it in different positioning threaded holes 1101. The bending height of the hinge plate 12 can be lowered to allow the limb to be bent downward. Further, it can be convenient for the patient to keep the limbs at different angles after moving. After a period of time, the rear fixing plate 3 is adjusted to be parallel to the front fixing plate 2, and then the limit link 503 is engaged with the slot 502 to restore the fixation of the joint bearing 10.

[0037] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all details in detail, nor do they limit the invention to the specific embodiments described. Obviously, based on the content of this specification, it is understood that a variety of modifications and changes can be made to these embodiments without departing from the principles and spirit of the present invention.
