Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to an adjustable limb fixation device. Background Art

[0002] After undergoing a radial artery or femoral artery puncture surgery, the patient's operated arm generally cannot make large movements. Otherwise, it will affect the surgical effect, resulting in a less satisfactory postoperative recovery. In more serious cases, the condition of the arm will deteriorate. Therefore, an arm fixation device is needed to immobilize the patient's arm after the operation, fix the patient's operated arm, and prevent the patient from subconsciously using the arm.

[0003] However, the lengths and thicknesses of patients' arms vary. In this regard, the current arm fixation devices have deficiencies. For example, it is not convenient to fix the patient's arm according to the length of the patient's arm, and it cannot well adapt to arms of different thicknesses, resulting in poor fixation effect on the patient's arm, and the comfort design for placing the patient's arm is not in place enough, which is not conducive to the rehabilitation of the patient's arm. Summary of the Invention

[0004] In view of the above-mentioned shortcomings or deficiencies of the prior art, the present invention provides an adjustable limb fixation device, which can adjust the fixation position according to the length of the patient's arm, and can be applicable to arms of different thicknesses, making the patient's arm more comfortable.

[0005] The technical implementation scheme of the present invention is: an adjustable limb fixation device, including a mounting frame, a slide rail, a slider, a hand-pressing component, a tightening component, and an adjusting component. A slide rail is fixedly connected between the tops of the two mounting frames. Two sliders are slidably connected to the slide rail. Each slider is provided with a hand-pressing component, each hand-pressing component is provided with a tightening component, and an adjusting component is provided on the side of each slider.

[0006] In addition, particularly preferably, the hand-pressing component includes a buckle plate, a rod frame, a volute spring, a resilient strap, a housing, a locking block, and a return spring. A buckle plate is hinged to the upper side of each slider. Two rod frames are fixedly connected to each buckle plate. A volute spring is connected to each rod frame. A resilient strap is connected between every two adjacent volute springs. A housing is fixedly connected to the side of each slider. A locking block is slidably connected to each housing. Each locking block contacts the adjacent buckle plate. A return spring is connected between each locking block and the adjacent housing.

[0007] In addition, particularly preferably, the tightening component includes a tightening strip and a pressing block. Two tightening strips are fixedly connected to the upper side of each slider. Two pressing blocks are fixedly connected to the lower side of each buckle plate. Each pressing block cooperates with the adjacent tightening strip.

[0008] In addition, it is particularly preferred that the adjusting assembly includes a rotating rod, a cam, a handle and a friction strip. A rotating rod is rotatably connected to the side surface of each slider. A cam and a handle are fixedly connected to each rotating rod. A friction strip is slidably connected to each slider. Each friction strip is slidably connected to the slide rail.

[0009] In addition, it is particularly preferred that a protection assembly is further included. A protection assembly is provided on each slider. The protection assembly includes an inflatable pad, a gas storage box, a pressing plate and a ventilation pipe. An inflatable pad is fixedly connected to the upper side surface of each slider. A gas storage box is fixedly connected to the side surface of each slider. A pressing plate is slidably connected to each gas storage box. Each pressing plate is in contact with the adjacent buckle plate. A ventilation pipe is communicated between each gas storage box and the adjacent inflatable pad.

[0010] In addition, it is particularly preferred that a support assembly is further included. A support assembly is provided on the slide rail. The support assembly includes a hand support block and a soft pad. A hand support block is slidably connected to the slide rail. The hand support block is fixedly connected to the adjacent slider. A soft pad is fixedly connected to the upper side surface of the hand support block.

[0011] In addition, it is particularly preferred that an elastic band is further included. An elastic band is fixedly connected to the upper side surface of the hand support block.

[0012] The beneficial effects of the present invention are as follows: 1. The present invention limits the slider through the friction strip. When it is necessary to adjust the fixed position according to the arm length of the patient, the handle can be rotated so that the friction strip no longer clings to the slider, and then the slider can be slid to adjust the fixed position of the patient's arm.

[0013] 2. The patient's arm is placed on the resilient strap, and the resilient strap can be released from the scroll spring, so that the patient's arm can be placed comfortably and can be applicable to arms of different thicknesses. Then, by buckling the buckle plate, the patient's arm can be fixed between the two buckle plates and the two resilient straps to perform postoperative braking on the patient's arm.

[0014] 3. When the buckle plate is buckled, the downward movement of the buckle plate will squeeze the pressing plate to make it move downward, and then push the gas in the gas storage box to flow into the inflatable pad along the ventilation pipe to inflate the inflatable pad, so that the patient's arm can be placed more comfortably, prevent pressing the patient's arm, and improve the comfort of the patient.

Specific embodiments

[0023] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0024] Embodiment 1: An adjustable limb fixation device, as Figures 1-7 shown, includes a mounting bracket 1, a slide rail 2, a slider 3, a hand pressing component, a tightening component and an adjustment component. A slide rail 2 is bolted between the tops of the two mounting brackets 1. Two sliders 3 are slidably connected to the slide rail 2. A hand pressing component is provided on each slider 3. A tightening component is provided on each hand pressing component. An adjustment component is provided on the side of each slider 3.

[0025] The pressing hand assembly includes a buckle plate 41, a rod frame 42, a volute spring 43, a resilient strap 44, a housing 45, a locking block 46, and a return spring 47. A buckle plate 41 is hinged to the upper side surface of each slider 3. Two rod frames 42 are bolted to each buckle plate 41. Each rod frame 42 is vertically arranged. A volute spring 43 is connected to each rod frame 42. A resilient strap 44 is connected between every two adjacent volute springs 43. A housing 45 is bolted to the side surface of each slider 3. A locking block 46 is slidably connected to each housing 45. Each locking block 46 contacts the adjacent buckle plate 41. A return spring 47 is connected between each locking block 46 and the adjacent housing 45 by a hook. The return spring 47 is used for the reset of the locking block 46.

[0026] The tightening assembly includes a tightening strip 51 and a pressing block 52. Two tightening strips 51 are bolted to the upper side surface of each slider 3. Two pressing blocks 52 are bolted to the lower side surface of each buckle plate 41. Each pressing block 52 cooperates with the adjacent tightening strip 51.

[0027] The adjusting assembly includes a rotating rod 61, a cam 62, a handle 63, and a friction strip 64. A rotating rod 61 is rotatably connected to the side surface of each slider 3. A cam 62 and a handle 63 are fixedly connected to each rotating rod 61. The cam 62 is located between the handles 63. A friction strip 64 is slidably connected to each slider 3. Each friction strip 64 is slidably connected to the slide rail 2.

[0028] Working principle: Initially, two locking blocks 46 lock one end of the adjacent buckle plate 41, and both friction strips 64 are closely attached to the side surface of the slide rail 2. The two sliders 3 cannot move along the slide rail 2. The nurse first installs the mounting bracket 1 on the hospital bed, and then rotates the two handles 63. The rotation of the two handles 63 drives the rotation of the two rotating rods 61, the rotation of the two rotating rods 61 drives the rotation of the two cams 62, and the rotation of the two cams 62 causes them to disengage from the two friction strips 64 and no longer press the two friction strips 64, so that the two friction strips 64 no longer closely adhere to the side surface of the slide rail 2. Then the nurse slides the slider 3, and the movement of the slider 3 drives the movement of the buckle plate 41, so that the slider 3 can be slid according to the length of the patient's arm to adjust the position where the two buckle plates 41 fix the patient's arm. After the adjustment is completed, the nurse rotates the two handles 63 in the reverse direction, so that the rotating rods 61 and the cams 62 rotate in the reverse direction. The reverse rotation of the cam 62 contacts and presses the friction strip 64, causing the friction strip 64 to move away from the cam 62 and re-closely adhere to the side surface of the slide rail 2 to limit the two sliders 3. After that, the nurse pulls the locking block 46 to move it away from the buckle plate 41, the return spring 47 is compressed, and the locking block 46 no longer locks the buckle plate 41. At this time, the nurse can turn up the buckle plate 41 and release the locking block 46. The reset of the return spring 47 drives the reset of the locking block 46. Then the nurse places the patient's arm on the two resilient straps 44. The patient's hand presses the two resilient straps 44, which causes the two resilient straps 44 to be released from the volute spring 43, so that the patient's arm can be placed comfortably and can be applicable to arms of different thicknesses. Then the nurse turns down the buckle plate 41. The buckle plate 41 contacts the locking block 46 and pushes the locking block 46 to move away from the buckle plate 41. The return spring 47 is compressed. When the buckle plate 41 continues to move downward, it disengages from the locking block 46. The reset of the return spring 47 drives the reset of the locking block 46, thus re-closing the buckle plate 41. The downward movement of the buckle plate 41 drives the two adjacent pressing blocks 52 to move downward. The downward movement of the pressing blocks 52 contacts the resilient strap 44 and cooperates with the adjacent tightening strip 51 to lock it, so that the resilient strap 44 can no longer be released from the volute spring 43, thereby fixing the patient's arm between the two buckle plates 41 and the two resilient straps 44 for postoperative immobilization of the patient's arm.

[0029] Embodiment 2: On the basis of Embodiment 1, as Figures 1-7 shown, it further includes a protection component. A protection component is provided on each slider 3. The protection component includes an air cushion 71, an air storage box 72, a pressing plate 73, and a ventilation pipe 74. The upper side surface of each slider 3 is bolted with an air cushion 71, the side surface of each slider 3 is bolted with an air storage box 72, a pressing plate 73 is slidably connected to each air storage box 72, each pressing plate 73 contacts the adjacent buckle plate 41, and a ventilation pipe 74 is communicated between each air storage box 72 and the adjacent air cushion 71.

[0030] When the buckle plate 41 moves downward, it will contact the adjacent pressing plate 73 and squeeze the pressing plate 73 to move it downward. The downward movement of the pressing plate 73 will push the gas in the air storage box 72 to flow into the inflatable pad 71 along the ventilation pipe 74, inflate the inflatable pad 71, so that the patient's arm can be placed more comfortably, prevent pressing the patient's arm, and improve the patient's comfort.

[0031] Embodiment 3: On the basis of Embodiment 2, as Figures 1-2 shown, it further includes a support assembly. The support assembly is provided on the slide rail 2. The support assembly includes a hand support block 81 and a soft pad 82. The hand support block 81 is slidably connected to the slide rail 2. The hand support block 81 is fixedly connected to the adjacent slider 3. The upper side surface of the hand support block 81 is fixedly connected with a soft pad 82.

[0032] The movement of the slider 3 close to the hand support block 81 will drive the hand support block 81 and the soft pad 82 to move together, thereby supporting the patient's hand so that the patient's hand can be placed comfortably.

[0033] Embodiment 4: On the basis of Embodiment 3, as Figures 1-2 shown, it further includes an elastic band 9. The upper side surface of the hand support block 81 is fixedly connected with an elastic band 9.

[0034] The elastic band 9 is provided on the hand support block 81, and the elastic band 9 can further improve the patient's comfort.

[0035] The above-described embodiments only represent the preferred embodiments of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
