Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an auxiliary bracket for wrapping bandages for patients with limb edema. Background Art

[0002] Bandages are commonly used in conservative treatment of lymphedema. By wrapping the bandage around the patient's swollen limb, a stable pressure is generated on the limb that counteracts muscle force, squeezing the edematous tissue and effectively promoting lymphatic return. When bandaging the swollen limb, due to the patient's weight, a lifting device is often required to elevate the limb, making it easier for medical staff to bandage the limb.

[0003] Existing lifting devices place the patient's limb on a support plate and then rotate the support plate through a rotating assembly to lift the patient's limb. However, the following problems may occur in actual operation:

[0004] 1. Usually, the patient's swollen limb needs to be bandaged throughout the limb. Existing bandages usually fix the limb to the device to prevent it from slipping off. When the limb is fixed to the device, the area in contact with the device cannot be bandaged. If this area needs to be bandaged, the patient's limb must be lifted off the device, the device must be moved, and then the patient's limb must be placed on the device for fixation. This operation is relatively complicated and requires lifting the patient's limb multiple times, which is quite laborious.

[0005] 2. Since different patients have different limb lengths, the position of the restraint component in the lifting device used to fix the patient's limbs needs to be adjusted according to the patient's limb length to avoid the situation where the restraint component cannot fix the patient's limbs. Utility Model Content

[0006] In order to solve the above problems, the purpose of the present invention is to provide an auxiliary bracket for wrapping bandages for patients with limb edema, which is convenient for wrapping the contact position between the patient's limbs and the device.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] The cam is secured to the upper edge of the support frame, and the cam is secured to the upper edge of the support frame, allowing the cam to be locked or unlocked when the cam is unlocked.

[0009] More preferably, a pair of elastic bands are symmetrically fixed on the left and right sides of each lifting plate, wherein the inner side of one of the elastic bands is provided with a hook surface and the outer side of the other elastic band is provided with a furry surface that cooperates with the hook surface to achieve fixation.

[0010] More preferably, an elastic airbag adapted to the placement groove is fixedly provided on the inner surface of the placement groove, and a plurality of elastic protrusions are fixedly provided at intervals on the upper surface of the elastic airbag.

[0011] More preferably, the clamping assembly includes two mutually hinged clamping plates and a return spring arranged between the two clamping plates on a side away from the bed board, and the turntable is rotatably fixed to the upper surface of the clamping plate located above.

[0012] More preferably, a driven gear is fixedly provided on the outer side of the turntable, a driving gear that meshes with the driven gear is rotated on the upper surface of the clamping plate away from the bed plate, and a second motor with an output shaft passing through the clamping plate and fixed to the shaft end of the driving gear is fixed on the lower surface of the clamping plate.

[0013] More preferably, the locking mechanism includes a plurality of pins which are adapted one by one with the sliders in each constraint assembly and are movably arranged on the sliders along the thickness direction of the sliders, and a plurality of pin holes which are spaced apart on the upper surface of the sliders along the extension direction of the sliders and are used to engage with the lower pins.

[0014] More preferably, the rotating assembly also includes a first motor for driving the support plate to rotate relative to the mounting plate; the support plate is rotatably connected to the two mounting plates through a rotating shaft circumferentially rotatably arranged between the two mounting plates, and the first motor is fixed to the outer side surface of any one of the mounting plates and the output shaft passes through the mounting plate and is fixedly connected to the end of the rotating shaft.

[0015] The utility model has the following beneficial effects:

[0016] By the cooperation of multiple sets of electric push rods and the lifting board, when it is necessary to wrap the patient's leg at the contact point with the device, there is no need to lift the patient's leg, move the device, and then place the patient's leg on the device again for operation, thereby improving the wrapping efficiency and facilitating the operation of the operator;

[0017] 2. The present invention arranges the sliding intervals of the restraint components in the slide rails, and can adjust the position of the restraint components according to the length of the patient's limbs, so that multiple groups of restraint components can support the patient's legs, thereby improving the stability of the lifting device in supporting the patient's limbs.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] An auxiliary bracket for wrapping bandages for patients with limb edema, comprising a clamping assembly 1 fixed to one side of a bed board 4, a rotating assembly 2 mounted on the upper surface of the clamping assembly 1, a plurality of restraining assemblies 3 movably arranged on the upper surface of the rotating assembly 2 along the length direction of the rotating assembly 2 and used to fix the patient's limbs, and a locking mechanism 5 for keeping the rotating assembly 2 and the restraining assembly 3 locked or unlocked; the rotating assembly 2 comprises a turntable 21 rotatably arranged on the upper surface of the clamping assembly 1 in the circumferential direction, a pair of mounting plates 22 symmetrically arranged vertically on both sides of the upper surface of the turntable 21, and a support plate 25 rotatably connected in the middle between the two mounting plates 22; a slide rail 251 extending along the length direction of the support plate 25 is embedded on the upper surface of the support plate 25, and each restraining assembly 3 is arranged in the slide rail 251 at intervals along the extension direction of the slide rail 251. ; Each group of the constraint components 3 includes a slider 31 that slides with the slide rail 251, a locking sub-assembly for keeping the slider 31 and the slide rail 251 locked or unlocked, an electric push rod 32 vertically fixed to the upper surface of the slider 31, and a lifting plate 33 fixed to the driving end of the electric push rod 32; the lifting plate 33 is provided with a placement groove 331 for placing the patient's limb along the length direction of the lifting plate 33; the rotating component 2 also includes a first motor 24 for driving the support plate 25 to rotate relative to the mounting plate 22; the support plate 25 is rotatably connected to the two mounting plates 22 through a rotating shaft 23 circumferentially rotatable between the two mounting plates 22, and the first motor 24 is fixed to the outer side surface of any one of the mounting plates 22 and the output shaft passes through the mounting plate 22 and is fixedly connected to the shaft end of the rotating shaft 23.

[0026] Taking the patient's legs as an example, the patient's swollen legs are placed on several lifting plates 33, and then the electric push rods 32 are extended to the appropriate positions from the patient's feet to the thighs. The closer to the patient's thighs, the shorter the extension length of the driving end of the electric push rod 32 is. The patient's legs are fixed and supported at intervals by several lifting plates 33. When it is necessary to wrap around the contact area between a single lifting plate 33 and the patient's legs, it is only necessary to retract the driving end of the electric push rod 32 corresponding to the lifting plate 33 to drive the lifting plate 33 to descend, so that the lifting plate 33 moves downward away from the patient's legs. At this time, the corresponding position of the patient's leg can be wrapped around the lifting plate 33, and the lifting plate 33 is driven when the wrapping is completed. The driving end of the electric push rod 32 corresponding to the lifting plate 33 extends until the lifting plate 33 stops when it contacts the patient's legs. Through the cooperation of multiple sets of electric push rods 32 and the lifting plate 33, when it is necessary to wrap the patient's legs and the contact point of the device, there is no need to lift the patient's legs, move the device, and then place the patient's legs on the device again for operation, which improves the wrapping efficiency and facilitates the operator's operation; by arranging the sliding interval of the restraint component 3 in the slide rail 251, the position of the restraint component 3 can be adjusted according to the length of the patient's limbs, so that multiple sets of restraint components 3 can support the patient's legs, thereby improving the stability of the lifting device in supporting the patient's limbs.

[0027] As a possible implementation of the present scheme, preferably, a pair of elastic bands 34 are symmetrically fixed on the left and right sides of each lifting plate 33, wherein the inner side surface of one of the elastic bands 34 is provided with a hook surface 341 and the outer side surface of the other elastic band 34 is provided with a furry surface 342 that cooperates with the hook surface 341 to achieve fixation; the two elastic bands 34 can further enhance the stability of the patient's limbs fixed on the device through the cooperation of the hook surface 341 and the furry surface 342.

[0028] As a possible implementation of the present scheme, preferably, an elastic airbag 35 adapted to the placement groove 331 is fixedly provided on the inner surface of the placement groove 331, and a plurality of elastic protrusions 351 are fixedly provided at intervals on the upper surface of the elastic airbag 35; the provision of the elastic airbag 35 can prevent the patient's limbs from being injured by the edge of the lifting plate 33, while further enhancing the stability of the patient's legs when placed on the lifting plate 33.

[0029] As a possible implementation scheme of the present invention, preferably, the clamping assembly 1 includes two clamping plates 11 hinged to each other and a return spring 12 arranged between the two clamping plates 11 on the side away from the bed board, and the turntable 21 is circumferentially rotatably fixed to the upper surface of the clamping plate 11 located above; through the cooperation of the two clamping plates 11 and the return spring 12, the disassembly and installation of the device can be facilitated, and the use and storage of the device can be facilitated.

[0030] As a possible implementation scheme of this solution, preferably, a driven gear 26 is fixedly provided on the outer side of the turntable 21, and a driving gear 27 meshing with the driven gear 26 is rotated on the upper surface of the clamping plate 11 away from the side of the bed board, and a second motor 28 is fixed on the lower surface of the clamping plate 11, whose output shaft passes through the clamping plate 11 and is fixed to the shaft end of the driving gear 27; the driving gear 27 is driven to rotate by the output end of the second motor 28, and the turntable 21 is driven to rotate by the engagement of the driving gear 27 with the driven gear 26, which can facilitate the adjustment of the direction of multiple groups of constraint components 3 to adapt to the angle of the patient's limbs, and facilitate the medical staff to operate the patient's swollen limbs.

[0031] As a possible implementation of the present scheme, preferably, the locking mechanism 5 includes a plurality of pins 51 which are adapted one by one with the sliders 31 in each constraint assembly 3 and are movably provided on the sliders 31 along the thickness direction of the sliders 31, and a plurality of pin holes 52 which are arranged at intervals on the upper surface of the slide rail 251 along the extension direction of the slide rail 251 and are used to engage with the lower pins 51.

[0032] The working principle of this device is:

[0033] The first step is to press the tail ends of the two clamping plates 11, then move the device so that the bed board is located between the clamping ends of the two clamping plates 11, and then release the two clamping plates 11 so that the device is fixed to the bed board under the action of the return spring 12;

[0034] In the second step, the second motor 28 is then driven to rotate the driving gear 27, so that the driven gear 26 drives the turntable 21 to rotate, thereby adjusting the angles of the plurality of restraint components 3 so that the direction of the limb is on the same horizontal line as the plurality of restraint components 3 when the patient wraps the limb;

[0035] The third step is to move the restraint assemblies 3 to a suitable position along the slide rails 251 , and then lift the patient's legs and place them on the lifting plates 33 in the restraint assemblies 3 ;

[0036] Step 4: Extend the electric push rods 32 to the appropriate position from the patient's feet to the thighs. The closer to the patient's thighs, the shorter the extension of the driving end of the electric push rods 32. At this time, the final position of the lifting plates 33 is required to abut against the bottom of the patient's legs.

[0037] In the fifth step, the patient's legs are finally fixed to the corresponding lifting plate 33 through the cooperation of the hook surface 341 and the fur surface 342.
