Description

Technical Field

[0001] The present application relates to the field of medical auxiliary devices, and in particular to a leg spreading device. Background Art

[0002] Perineal eczema is a common skin disease in bedridden patients. It is mainly manifested by redness, swelling, thickening, roughness, itching and pain on the inner thigh and scrotum. In severe cases, epidermal ulceration may occur. Perineal eczema is more common in people with allergic constitutions, those who are in a humid environment for a long time and those with reduced resistance.

[0003] Patients who are bedridden for a long time generally have complications such as muscle atrophy and joint contracture. Muscle atrophy may cause the patient to be unable to exert force to separate the thighs on his own, which will cause the inner thighs to fit against the scrotum, the back of the thighs to fit against the mattress, etc., causing local skin to be airtight, and then cause local eczema. At present, in addition to drug treatment, the most effective method is to keep these positions breathable and dry. Therefore, the general practice is to bend the lower limbs of bedridden patients, and then pry them apart from the knees to separate the inner thighs. The current conventional operation to prevent the thighs from closing is to use towel pads and pillows to maintain the normal position of the lower limbs, but these structures will deform and the effect is not good. In the prior art, a lower limb adduction spreader (application number: 201821386246.7) is disclosed. The device allows the patient to hold a hand push rod to move the pressure rod downward, and pull the movable rod out to expand it to both sides through the support rod on the pressure rod, so that the patient can open the hips. However, the spreader does not bend the patient's lower limbs first and then open them, but directly opens the patient's knee joint. In fact, the back of the thigh will still be in contact with the mattress, making the skin airtight. Moreover, because a large area of ​​the patient's lower limbs are in contact with the mattress, there is a certain friction. It takes a lot of force to open the patient's knee joint by pressing down, so it is difficult for the patient to use the spreader. Summary of the invention

DETAILED DESCRIPTION

[0026] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0027] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0028] The defect that the prior art cannot adjust the posture of the patient's lower limbs and then guide the thighs to open to a suitable angle and fix them. After careful analysis, the inventor found that the main reason for the above problem is that in general, the lower limbs of bedridden patients are placed on the bed and parallel to the mattress. If the patient's thighs are directly opened, first, the contact area between the thighs and the mattress is large, resulting in large friction, and medical staff need to lift them to complete the operation. Second, the thighs opened in this way still have a large area of ​​contact with the mattress on the back of the thighs and the lower side of the buttocks, which is prone to airtightness for a long time. These places are also prone to eczema or fungal infection for patients with low immunity. Therefore, it is necessary to guide the patient's lower limbs to bend the knee joint position, and then open the thighs, so as to expose the inner thighs and the surrounding skin to the greatest extent. The patent scheme "a lower limb adduction spreader" disclosed in the prior art, when used, the corresponding structure is put on the patient's lower limbs, and the patient holds the hand push rod to move the pressure rod downward, and the support rod on the pressure rod is pulled out to expand the movable rod to both sides, so that the patient can open the hip. It may not be applicable in actual use. First, as mentioned above, the lower limbs in contact with the mattress have friction, and it may take a lot of force to open the legs when pressing down. If too much force is applied, the legs may be opened too much, causing discomfort to the patient; secondly, the opener does not have the function of adjusting the patient's lower limbs to expose the inner thigh to the maximum; finally, the solution mentions that the patient uses the opener, and the patient is generally in a lying or reclining position. If the patient uses the opener, the patient's body posture needs to do sit-ups, and may not be able to reach the push rod of the opener at all. Therefore, it may not be possible to adjust the posture of the lower limbs to guide the thigh to open to a suitable angle. Based on the above analysis, the inventor has made structural improvements to the opener.

[0029] Figure 1-7 As shown, in one embodiment of the leg spreading device of the present application, the device includes a driving device, and the driving devices are two, which are distributed on the left and right sides of the bed and are located between the patient's knee joint and thigh;

[0030] The driving device includes a lower limb adjustment component, a driving component and a guide component. The lower limb adjustment component is used to adjust the flexion state of the patient's knee joint and open the thigh in combination with the guide component. The lower limb adjustment component includes a collar component 7 that is sleeved between the knee and the thigh (femur position) to Figure 2The driving device on the left side of the figure is used as a reference benchmark. The left side of the collar component 7 is movably connected to a laterally arranged telescopic rod 6. A first baffle 61 with a circular ring shape is welded on the middle right side of the telescopic rod 6. The first baffle 61 and the collar component 7 have a certain spacing to form a space. A circular sleeve 3 with an inner wall matching the outer wall of the telescopic rod is sleeved on the outside of the right side of the telescopic rod 6. The telescopic rod 6 can move left and right in the sleeve 3. A swing angle rod 8 is welded on the bottom surface of the sleeve 3. The swing angle rod 8 is a circular right-angle rod. The swing angle rod 8 extends downward and then bends to the left.

[0031] The driving assembly is used to control the swinging of the lower limb adjustment assembly to drive the patient's lower limbs to achieve knee flexion, and cooperate with the guide assembly to make the collar component 7 drive the patient's thigh to move in an arc trajectory. The driving assembly is arranged on the left side of the lower limb adjustment assembly. The driving assembly includes a frame, which includes a rectangular frame body 1 with an open top. The top surface of the frame body 1 is fixed with a top cover 11 by screws, so that the frame is a vertical rectangular fixed frame; arc-shaped and vertically arranged guide ribs 13 are arranged on the opposite end surfaces inside the frame body 1. A rectangular driving box 9 that can move up and down is arranged inside the frame. The front and rear end surfaces of the driving box 9 are respectively provided with grooves (not shown) that match the guide ribs 13 to limit the rotation or swing of the driving box 9 when it moves up and down; a through hole that penetrates to the left side is opened on the right side of the driving box 9, and a first motor 70 fixed by screws is installed on the left side of the driving box 9. The rotating shaft of the first motor 70 extends into the through hole, and the left-bent end of the swing angle rod 8 passes through the through hole on the right side of the driving box 9 and is fixedly connected to the rotating shaft of the first motor 70 (welded or screwed), such as Figure 1 As shown, arrows are marked on the surface of the driving box 9 to help understand the motion trajectory of the swing angle rod 8. The first motor 70 rotates along the driving trajectory arrow to swing the telescopic rod 6 of the lower limb adjustment assembly toward a low position, so that the collar component 7 corresponds to the patient's lower limb. The first motor 70 is reset, driving the lower limb adjustment assembly to reset, that is, driving the patient's lower limb to a high position and adjusting it to a knee flexion state.

[0032] In addition, a vertically arranged and rotatable drive shaft 30 is provided inside the frame. Specifically, a coaxial through hole is provided at the bottom of the frame 1 and the top of the top cover 11. The drive shaft 30 is installed in the coaxial through hole. The drive shaft 30 is a screw structure. A bearing ( Figure 1 The bottom end of the drive shaft 30 is fixed in the bearing to prevent the bottom end of the drive shaft 30 from swinging when rotating. The top surface of the drive box 9 is provided with a threaded through hole that penetrates the bottom surface. The drive shaft 30 penetrates into the threaded through hole of the drive box 9 and passes out from the bottom of the drive box 9 to control the movement trajectory of the drive box 9. In order to improve the stability of the drive box 9 when it moves up and down, as shown in FIG. Figure 3As shown, threaded sleeves ( Figure 1 The driving shaft 30 extends into the threaded sleeve, increasing the contact of the threaded surface, which can make the driving box 9 move more smoothly. The top of the top cover 11 of the frame is installed with a second motor 2 fixed with screws, and the rotating shaft of the second motor 2 is fixedly connected to the top of the driving shaft 30. The second motor 2 rotates forward and reverse to drive the driving shaft 30 to rotate, thereby moving the driving box 9 up and down in the frame.

[0033] The guide assembly is used to guide the collar member 7 to move to the left, so that when the driving assembly drives the collar member 7 to move downward, the guide assembly drives the collar member 7 to move to the left, so that the movement trajectory of the collar member 7 forms an arc trajectory corresponding to the opening of the thigh. The guide assembly includes a vertical rod 10 and a horizontal rod 20 connected at right angles. The vertical rod 10 is located at the right end of the horizontal rod 20 and extends upward. Figure 3 A bayonet 102 is provided on the rear side of the top of the vertical rod 10. The bayonet 102 is sleeved on the telescopic rod 6 and on the right side of the first baffle 61, that is, between the aforementioned first baffle 61 and the collar component 7, and a part of the telescopic rod 6 at this position is sleeved. A vertical groove 101 is provided at the bottom of the bayonet 102. The bayonet 102, the vertical groove 101 and the telescopic rod 6 are clearance-matched. When the lower limb adjustment assembly moves downward, the telescopic rod 6 on the right side of the first baffle 61 moves in the vertical groove 101; the cross bar 20 is arranged at the bottom of the frame, such as Figure 2 , 5 As shown in FIG. 6 , the left side of the crossbar 20 is sleeved with a guide sleeve 40, and a threaded hole is opened at the left end. A limiter 60 is installed in the threaded hole. The limiter 60 is preferably a bolt. The edge of the nut of the cover bolt can support the left end surface of the guide sleeve 40 to prevent it from falling out. A cylindrical pin 90 is welded to the front end of the guide sleeve 40, and a guide rod 50 is hinged on the cylindrical pin 90. Figure 6 As shown, a square plate is welded at the bottom of the drive box 9, and a cylindrical pin 90 is also welded at the front end of the square plate. The other end of the guide rod 50 is hingedly connected to the cylindrical pin 90 at the bottom of the drive box 9 and is tilted upward to the right. In order to prevent the guide rod 50 from falling out, a square plate can also be welded to the front end of the cylindrical pin 90 hinged to the guide rod 50 tilted upward to the right.

[0034] When the drive box 9 moves downward, the guide rod 50 is pressed down, so that the hinged end of the guide rod 50 and the guide sleeve 40 moves to the left and pushes the guide sleeve 40 to move to the left. The guide sleeve 40 presses the limiter 60 to drive the cross bar 20 to move to the left, and the vertical rod 10 squeezes the first baffle 61 on the telescopic rod 6 to the left through the bayonet 102 and the vertical groove 101, driving the ring component 7 to move to the left, so that the movement trajectory of the ring component 7 forms an arc trajectory corresponding to the opening of the thigh.

[0035] The patient's legs are fixed by the collar component 7, and the entire device is used to adjust the posture of the patient's lower limbs and guide the thigh to open to a suitable angle. Since the position of the thigh changes when it swings, if the Velcro structure is directly used, the thigh skin may be damaged when the thigh swings open, causing the thigh skin to feel uncomfortable due to squeezing or pulling. In order to solve this problem, the collar component 7 of this embodiment includes a cylindrical fixed ring 701, a movable ring 702 and a cushion layer 703. The movable ring 702 is rotatably installed in the fixed ring 701 (clearance fit), and the front and rear ends of the movable ring 702 are respectively provided with outward-turned retaining rings. The retaining rings clamp the movable ring 702 in the fixed ring 701 to prevent the movable ring 702 from coming out of the fixed ring 701. The cushion layer 703 is fixed to the inner wall of the movable ring 702 by glue. The cushion layer 703 can be a general cushion or an air bag. The cushion is fixed by adjusting the position on the thigh, while the air bag is fixed on the thigh by inflation without adjusting the position.

[0036] Since the collar member 7 is placed on the patient's thigh, the angle between the thigh axis and the mattress changes during the process of lifting the thigh, so the collar member 7 needs to be able to adjust the angle to suit the thigh when it is lifted. Figure 7 An adjusting component 80 is installed between the collar component 7 and the telescopic rod 6. The adjusting component 80 includes an arc-shaped connecting plate 801 fixedly connected to the outer wall of the fixing ring 701 by screws 4. A cylindrical boss is welded to the left wall of the connecting plate 801, and a disc-shaped flange 802 is welded to the left end of the boss. The adjusting component 80 also includes a connecting sleeve 803. The left end of the connecting sleeve 803 is open and the right end is closed. A hole for the boss to pass through is opened in the middle of the right end. The boss can rotate in the hole, and the connecting sleeve 803 is restricted from escaping from the boss by the flange 802.

[0037] The left end of the connecting sleeve and the right end of the telescopic rod are detachably fixedly connected. The most common detachable fixed connection is a threaded connection, that is, threads are provided on the inner wall of the connecting sleeve and the outer wall of the right end of the telescopic rod. A threaded connection is adopted. In the present embodiment, a method is also provided, that is, coaxially distributed threaded holes are provided on the outer walls of the connecting sleeve 803 and the telescopic rod 6, the left end of the connecting sleeve 803 covers the right end of the telescopic rod 6, and the screw 4 is screwed into the coaxial threaded hole for fixing.

[0038] In order to improve the effect of resetting the telescopic rod 6 of the lower limb adjustment assembly when the driving assembly is reset, a second annular baffle 31 is welded on the right end of the sleeve 3; a spring 5 is sleeved on the telescopic rod 6, and the spring 5 is located between the first baffle 61 and the second baffle 31. When the driving assembly is reset, the spring 5 will press the first baffle 61 to the right, push the telescopic rod 6 to the right, and push the vertical rod 10 to the right through the first baffle 61 to reset.

[0039] A clearance notch 12 is provided at the middle rear side of the top surface of the top cover 11 of the frame to allow the telescopic rod 6 to pass through.

[0040] A transversely arranged fixed sleeve 14 is provided on the bottom surface of the frame, and the cross bar 20 is movably arranged in the fixed sleeve 14 to prevent the cross bar 20 from swinging left and right.

[0041] In addition, in order to prevent the telescopic rod 6 from falling out of the sleeve 3, at least one transversely arranged long strip first limiting groove 62 is opened on the outer wall of the telescopic rod 6, and a screw hole is opened on the outer wall of the sleeve 3, and a screw 4 is screwed into the screw hole, and the threaded end of the screw 4 extends into the first limiting groove 62; in order to limit the rotation of the cross bar 20, at least one transversely arranged long strip second limiting groove 201 is opened on the outer wall of the cross bar 20, and a screw hole is opened on the outer wall of the fixed shaft sleeve 14, and a screw 4 is screwed into the screw hole, and the threaded end of the screw 4 extends into the second limiting groove 201.

[0042] When using this tool, refer to Figure 1 and Figure 2 , the driving devices are respectively installed on both sides of the bed, and the swing angle rod 8 of the lower limb adjustment component is controlled by the first motor 70 to swing in the low direction to both sides of the patient's thighs, and the ring component 7 is put on the appropriate position of the patient's lower limbs. The connecting circular sleeve 803 of the adjusting component 80 is connected to the right end of the telescopic rod 6, and the first motor 70 is driven to reset. The swing angle rod 8 drives the telescopic rod 6 and the ring component 7 to swing upward. During the swinging process, the thigh is lifted and the knee is bent. At this time, the soles of the feet support the mattress of the bed.

[0043] refer to Figure 3 and Figure 4 The second motor 2 drives the driving shaft 30 to rotate, so that the driving box 9 moves downward, driving the lower limb adjustment assembly to move downward, and the driving box 9 moves downward to press the guide rod 50, so that the hinged end of the guide rod 50 and the guide sleeve 40 moves to the left and drives the guide sleeve 40 to move to the left, and the guide sleeve 40 drives the cross bar 20 to move to the left, and the vertical rod 10 then squeezes the first baffle 61 on the telescopic rod 6 to the left through the bayonet 102 and the vertical groove 101, driving the ring component 7 to move to the left, so that the movement trajectory of the ring component 7 forms an arc trajectory corresponding to the opening of the thigh.

[0044] During resetting, the driving assembly drives the driving box 9 to move upward, so that the lower limb adjustment assembly moves upward, and the driving box 9 drives the guide rod 50 to move upward. The spring 5 pushes the first baffle 61, the telescopic rod 6, the ring component 7 and other mechanisms to move to the right, and drives the vertical rod 10 to move to the right. The hinged end of the guide rod 50 and the guide sleeve 40 cooperates with the thrust of the spring 5 to push the first baffle 61 and drive the vertical rod 10 to move to the right together until the spring 5 is fully expanded and the resetting is completed.

[0045] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present application should be within the protection scope of the present application.
