Detailed Description
In order that those skilled in the art will better understand the invention and thus more clearly define the scope of the invention as claimed, it is described in detail below with respect to certain specific embodiments thereof. It should be noted that the following is only a few embodiments of the present invention, and the specific direct description of the related structures is only for the convenience of understanding the present invention, and the specific features do not of course directly limit the scope of the present invention. Such modifications and variations that may be apparent to a person skilled in the art, while guided by the teachings herein provided, are considered to be within the scope of the invention as claimed.
A limb swinging device for nursing comprises a limb swinging mechanism 100 and a fixed component 500, wherein the limb swinging mechanism 100 and the fixed component 500 are detachably matched. The fixing component 500 is used for integrally fixing the device, and may be fixedly connected to a carrier such as a nursing bed, a hospital bed or a general bed, or other fixable devices, without limitation; the limb swinging mechanism 100 is used for swinging, reciprocating and the like to drive the limb to move correspondingly for rehabilitation and nursing. The limb swinging mechanism 100 and the fixing component 500 are detachably connected, so that the defect that other existing limb swinging devices occupy space when not in use can be overcome.
Fig. 1 and 2 show an application scenario of the device when the device is fitted to a hospital bed, wherein fig. 2 is a schematic view of the device when the device is formed as a left-right leg swing device and fitted to a hospital bed, respectively, and fig. 1 is a schematic view of the device after main components are removed from the hospital bed, namely, a schematic view of the device in a storage state. When the rehabilitation training of the limb swing is required, the limb swing mechanism 100 is connected with the fixing component 500 to form a use state as shown in fig. 2, so that the limb swing mechanism 100 is fixed; since the fixing component 500 is fixed at the tailstock 64 or the bed 65, the feet of the user can be placed in the limb swinging mechanism 100 and driven by the limb swinging mechanism to move accordingly after the user lies on the bed plate 63, and the swinging process is shown in fig. 3a and 3 b. In which fig. 3a shows a schematic view without swing, from which it can be seen that the leg is also of a certain degree of flexion, which avoids safety problems during swing (which might cause the patient to shift as a whole if the leg were straight in the initial situation, rather than the leg swinging in a bending manner), and fig. 3b shows a schematic view during swing, from which it can be seen that the patient's leg is of a more pronounced degree of flexion. Under the drive of the limb swinging mechanism 100, the legs of the patient can perform a circulating motion between fig. 3a and 3b, so that the limb can be obviously moved and recovered. Of course, it is not intended that the maximum degree of flexion of the device is as shown in fig. 3b, and fig. 3a and 3b are merely schematic and effective illustrations of the swinging process of the swinging device of the present invention, and do not limit the swinging amplitude of the device of the present application.
After use, the limb swing mechanism 100 can be separated from the fixing component 500, and the whole limb swing mechanism 100 is stored, for example, placed at the bottom of a bed or in a cabinet; the fixing component 500 is generally fixed at the bed end 64, has small volume and is positioned at two positions of the bed end 64, and does not influence the use of the bed for basic rest function; fig. 2 shows a schematic view of a bed with the device with the limb swing mechanism 100 stowed. Fig. 4 shows a schematic structural view of the limb swinging mechanism 100 in an embodiment, more specifically a schematic view of the left leg swinging mechanism, which is an integral component and has a relatively regular surface for easy storage.
To achieve swinging of a patient's limb, such as the lower limb, the main functional components of the limb swinging mechanism 100 of the present invention include the support frame 103, the slider assembly 210, and the transmission assembly 220. The rack 103 is provided with slide rails 1031, and the slide rails 1031 are preferably a pair of slide rails provided on the rack 103 so as to face each other in the vertical direction. The slider assembly 210 is slidably engaged to the support 103, and more specifically to the slide 1031, such as by a pulley assembly 104 that includes at least one pulley. The transmission component 220 is connected with the sliding block component 210 and drives the sliding block component to reciprocate along the bracket 103 so as to drive the tail end of the limb to do synchronous reciprocating motion, thereby generating the limb swinging effect as shown in figures 3a and 3b and achieving the aim of rehabilitation and nursing. In the present invention, swing is a description of the effect on the limb (e.g., leg) that is the overall movement effect achieved by the reciprocating translational motion of the slider assembly 210 and the corresponding translation of the extremity of the limb.
In some preferred embodiments, the transmission assembly 220 may include a transmission belt 221 and a synchronous pulley 222, and the synchronous pulley 222 is directly or indirectly disposed on the support 103, for example, via a synchronous pulley fixing frame 2221 fixed on the support 103. The driving belt 221 may be an open timing belt, both ends of which are connected to form a closed loop shape and are tensioned by at least two timing pulleys 222, and the slider assembly 210 is fixed in position on the driving belt 221 such that when the driving belt 221 is driven to rotate, the slider assembly 210 is moved accordingly. It should be noted that the synchronous pulley 222 in the present application does not refer to a conventional unpowered idler, but may be a synchronous pulley driving wheel that can tension the transmission belt; alternatively, a synchronous belt driving wheel may be additionally provided on the basis, which is not limited herein.
As shown in fig. 5 to 7, in a more preferable case, both ends of the open timing belt are connected by the slider assembly 210 to form a closed loop shape, i.e., the slider assembly 210 simultaneously functions as a slider and a timing belt connection, which is advantageous to simplify the structure and reduce the cost. For a specific embodiment, as shown in fig. 7, the slider assembly 210 includes a slider 211 and a fixed connecting block 212, both ends of the driving belt 221 are fitted between the slider 211 and the fixed connecting block 212, and the slider 211 and the fixed connecting block 212 are connected and fixed to clamp both ends of the driving belt 221. Preferably, the two ends of the transmission belt 221 are spaced apart from each other, and a spacer 2121 having a thickness corresponding to the thickness of the transmission belt 221 is disposed at the space between the two ends to adjust the tightness of the transmission belt 221 so as to make it reasonable; and the length of the transmission belt 221 can be adjusted by loosening the connection between the sliding block 211 and the connection fixing block 212 and adjusting the end fixing position of the transmission belt 221 and then fixing again when needed later, so that the tensioning effect of the transmission belt 221 is ensured to be in accordance with the expectation.
Of course, the belt 221 may also be a closed endless timing belt, and the slider assembly 210 is fixed in position on the belt 221 to move with it; meanwhile, in consideration of the problem of tension variation caused by looseness of the synchronous belt after subsequent use, at least one synchronous pulley 222 may be movably disposed on the bracket 103, for example, by using a strip-shaped fixing groove and a fixing screw, which are commonly used in the prior art, or by using an eccentric shaft for fixing, which is also commonly used, to realize adjustment within a certain range.
As shown in fig. 5, the driving assembly 220 further includes a transition wheel 223, which is also disposed on the bracket 103 to control the shape of the driving belt so that the sliding block 211 can move normally, which is a very useful design for the size selection of the tension wheel, and the tension of the driving belt can be adjusted to the desired shape by introducing the transition wheel 223.
As shown in fig. 5-7, a pair of slide rails 1031 are disposed on one side of the bracket 103, and a pulley 104 is disposed on the side of the slider 211. The pulleys 104 are preferably divided into an upper pulley 1041 and a lower pulley 1042, and the upper pulley 1041 and the lower pulley 1042 are respectively composed of at least two pulleys; the upper pulley 1041 and the lower pulley 1042 are respectively engaged with the upper rail and the lower rail of the rail 1031, and are fixed to the slider 211 by a pulley shaft and a fixing nut 1043.
Preferably, at least one of the upper pulley 1041 and the lower pulley 1042 is fixed by the eccentric shaft 105 (i.e. the pulley shaft thereof is the eccentric shaft 105), the eccentric shaft 105 can be rotated by the pulley fixed by the eccentric shaft 105 to adjust the fit clearance between the upper and lower pulleys in the slide rail of the bracket 103, and the pulley fixing nut 1043 is tightened after adjustment, so as to ensure that the sliding block 211 is well fitted with the slide rail 1031. As shown in fig. 7e, the eccentric shaft 105 includes a first shaft portion 1051 and a second shaft portion 1052, the axes 1053 and 1054 of which are eccentrically disposed, the first shaft portion 1051 and the second shaft portion 1052 are respectively used for connecting to the bracket 103 and the pulley 104, so that the second shaft portion 1052 can be vertically offset by a certain amount by the rotation of the first shaft portion 1051 relative to the bracket 103, i.e. the pulley 104 has a certain vertical floating space.
Of course, the above-mentioned manner of engaging the pulley with the pulley is a preferred embodiment of the present invention, and in practical applications, the number of the sliding rails, the arrangement position, the number of the pulleys and the engagement position thereof on the sliding block can be simply changed, which is anticipated and expected.
As shown in fig. 5-6, the limb swinging mechanism 100 preferably further comprises a driving motor 110, the driving motor 110 is disposed on the support frame 103, and an output end of the driving motor 110 is connected to a synchronous pulley 222 to drive the driving belt 221 to rotate. In addition, the limb swinging mechanism 100 further comprises an upper shell 101 and a lower shell 102, the upper shell 101 and the lower shell 102 respectively cover the support 103 from the upper direction and the lower direction, so that the main action components of the limb swinging mechanism 100 are covered in the upper shell and the lower shell to form an overall structural schematic diagram as shown in fig. 4, and therefore on one hand, the relevant action components can be protected, and on the other hand, the limb swinging mechanism is more attractive and easy to use and store. Of course, in view of the functionality of the limb swinging mechanism 100, one or both of the upper shell 101 and the lower shell 102 may have corresponding strip-shaped grooves to support the swinging function of the limb fixation assembly 300. A handle 1011 is further provided on the upper shell 101 so as to provide a holding position; the bottom of the lower case 102 is provided with a bottom plate 1021 to increase the stability of the limb swing mechanism 100, and the bottom plate 1021 is preferably arranged at an angle perpendicular or substantially perpendicular to the swing direction to improve the stability of the limb swing mechanism 100 during swing.
For safety, the limb swinging mechanism 100 may further comprise a support wheel assembly 120 fixed on the frame 103 and disposed at the same height or plus or minus a certain value as the movement line of the sliding block 211, so that after the end of the limb of the patient is fitted on the limb fixing assembly 300, the limb has a certain degree of flexion, even if the angle θ between the end of the limb and the sliding movement line is 5-30 °, preferably 10-15 °, and the practical effect thereof can be shown in fig. 3 a. This prevents the swinging of the limb swinging mechanism 100 from acting erroneously so that the patient is displaced as a whole rather than bending the limb, which is not intended to be seen and is prone to safety hazards.
As shown in fig. 9, the driving motor 110 may be disposed in the idler assembly 120 in the best case. The riding wheel assembly 120 comprises a riding wheel main body 121, a cavity is formed in the riding wheel main body 121 to allow the driving motor 110 to be arranged in the cavity, a foam wheel 122 or a foam is sleeved outside the riding wheel main body 121, a hollow protective cover 123 is arranged at the outer end of the riding wheel main body 121, a cooling fan 124 is arranged behind the protective cover 123, and the driving motor 110 and the riding wheel assembly 120 are both connected to the support 103 through a motor support 111.
The fixing assembly 500 of the present invention includes a first connecting mechanism 520 and a fixing member 510, wherein the first connecting mechanism 520 is fixed on the bed 65 or the tailstock 64 through the fixing member 510; the limb swinging mechanism 100 comprises a second connecting mechanism 530 which can be used for matching with the first connecting mechanism 520 of the fixed component 500, and the second connecting mechanism 530 can limit the limb swinging mechanism 100 and the fixed component 500 in the moving direction of the sliding block component 210 after being matched and connected with the first connecting mechanism 520, so that the limit limb swinging mechanism 100 can be fixed through the fixed component 500. Therefore, when not in use, the limb swing mechanism 100 and the fixed component 500 can be separated, the limb swing mechanism 100 can be accommodated, and the fixed component 500 has small volume and does not influence daily use. The first connection mechanism 520 and the second connection mechanism 530 can be coupled in various ways, such as by screwing, snapping, and other detachable connections known in the art.
As shown in fig. 10a-c and 11, in a preferred embodiment, the first connecting mechanism 520 includes two clamping plates 522 which are oppositely spaced apart, one end of each clamping plate 522 is expanded outwards to form an opening portion 5221 and a clamping portion 5222 in a matching manner, and the inner diameter of the opening portion 5221 is larger than that of the clamping portion 5222. The first connecting mechanism 520 further comprises a housing 521 for accommodating therein a clamping plate 522, a spacer block 523 and the like, forming a complete structure as shown in fig. 10 a.

According to different heights of patients, the matching position of the second connecting mechanism 530 and the limb swinging mechanism 100 can be adjusted after the locking wheel 535 is unscrewed, so that the extending length of the second connecting mechanism 530 is different, and the locking wheel 535 can be screwed and unscrewed to fix the second connecting mechanism 530 and the limb swinging mechanism 100 so as to be matched with patients with different heights for use.
As shown in fig. 5-8 and 14, the limb swinging mechanism may further include a limiting device 400, where the limiting device 400 includes a lead screw fixing bracket 401, a lead screw 402, a guide rod 403, an adjusting motor 404, a limiting assembly 410, and a limiting block.

Namely, after the sensing limit fails, the mechanical limit can still be used for supplementary limit, so as to avoid the adverse effect on the patient caused by exceeding the expected swing amplitude; of course, a certain amount of travel interval can be allowed between the physical limit and the sensing limit so as to protect the motor, the limit device and other components better, and the physical limit and the sensing limit can be realized through the relative arrangement position (distance) of the physical limit and the sensing limit. In addition, the physical limit can be used independently in cooperation with motor control, that is, when the current of the motor is increased after the physical limit is performed, the current of the motor is monitored to control the motor to stop and rotate reversely, so that the sliding block 211 moves reversely.
