Description

Technical Field

[0001] This application relates to the technical field of medical auxiliary devices, and particularly to an upper limb fixation device for hemiplegic patients. Background Art

[0002] Currently, during the subsequent rehabilitation treatment of hemiplegic patients, for the fixation of the affected upper limb, a hard straight board or a flexible cloth is generally placed at the bottom of the arm, and then hung around the neck through a hanging strap. Some also directly use the upper limb fixation tools for orthopedic patients for fixation.

[0003] Such fixation tools cannot specifically solve the problems faced by hemiplegic patients during the rehabilitation treatment process. For example, the existing fixation devices lack a limiting structure for the hand, making the patient's hand only in a suspended state, reducing the patient's comfort, and at the same time easily causing poor blood circulation in the patient's hand, which is not conducive to rehabilitation treatment. For another example, since the affected limb of the patient is difficult to exert force, the structure of the existing fixation device is relatively fixed, and it is difficult for the patient to change the posture of the affected limb by himself during long-term use, which is not conducive to blood circulation in the affected limb and thus not conducive to rehabilitation treatment.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures, technologies, etc. are proposed to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details.

[0030] As Figure 1 and Figure 2 As shown, the present application constructs a hemiplegic patient upper limb fixation device 1, which includes a sling 10 and a supporting structure 20. The two ends of the sling 10 are respectively connected to the supporting structure 20 and are used to hang around the patient's neck to position the supporting structure 20. The supporting structure 20 is used to support the affected limb of the patient, and in cooperation with the sling 10, the affected limb of the patient can be placed in front of the chest in a natural bent state.

[0031] Specifically, the supporting structure 20 includes a first supporting part 21 and a second supporting part 22. Among them, the first supporting part 21 is used to support the patient's hand, and the second supporting part 22 is used to support the patient's forearm. The first supporting part 21 is arranged at one end of the second supporting part 22 and is rotatably connected to the second supporting part 22. The first supporting part 21 is also provided with a supporting space 211 for receiving the five fingers of the patient respectively. The supporting space 211 includes five finger supporting cavities, corresponding to the five fingers of the patient respectively, and each finger supporting cavity is respectively adapted to the shape of the corresponding finger in the extended state.

[0032] When the patient is wearing the device, the patient's hand is located on the first supporting part 21, and the five fingers are respectively received in the receiving space 211. The patient's forearm is located on the second supporting part 22. The sling 10 is hung around the patient's neck, so that the patient's upper arm (posterior arm) is located at the side of the body, the forearm forms a certain angle with the upper arm and is located in front of the patient's chest. When the patient wants to move the wrist, the mutual rotation between the first supporting part 21 and the second supporting part 22 can be controlled, so as to realize the rotation of the wrist.

[0033] By providing the first supporting part 21 in this application, the patient's hand can be supported. When the patient uses the upper limb fixing device 1 for hemiplegic patients, the hand will not bend and droop, causing problems such as blood circulation blockage and edema.

[0034] By providing a receiving space 211 including five finger receiving cavities on the first supporting part 21 in this application, when the patient uses it, the patient's five fingers can be respectively in an extended state in the five finger receiving cavities and will not be in a curled or contractured state, which is beneficial to assisting the patient to extend the fingers and avoiding muscle curling and contracture.

[0035] By rotatably connecting the first supporting part 21 and the second supporting part 22 in this application, when the patient wears the upper limb fixing device 1 for hemiplegic patients, the patient can independently realize the rotation of the affected limb (mainly the wrist), avoid the affected limb from maintaining the same posture for a long time, ensure normal blood circulation, and at the same time can also exercise the patient's muscles.

[0036] In some embodiments, the first supporting part 21 can be set as a glove shape. The part corresponding to the palm is made of a rigid material, and the part corresponding to the back of the hand is made of a flexible material (or the whole first supporting part 21 is made of a rigid material). Or, the first supporting part 21 can also be set as a semi-glove shape. The part corresponding to the palm and the part corresponding to the five fingers are both in a glove-like wrapped structure and made of a rigid material, and the rest is exposed. Or, the first supporting part 21 can also be set as a plate structure (or at least part of it has a certain arc-shaped plate-like structure). By providing a plurality of finger spacers on the plate structure, the separation of the five fingers is realized. By connecting elastic bands (or rigid fixing structures) between every two adjacent finger spacers, the fixation of the patient's five fingers in the extended state is realized. There are many potential situations, as long as the separation of the patient's five fingers and the positioning in the extended state can be realized, and they are not listed one by one here.

[0037] It should be understood that when the first supporting part 21 is set as a plate structure (or at least part of it has a certain arc-shaped plate-like structure), its shape can be various shapes such as rectangular, polygonal, racetrack-shaped, irregular-shaped, palm-shaped, etc., and no specific limitation is made here.

[0038] It should be understood that when the first supporting part 21 is arranged in a glove shape, the inner space of the first supporting part 21 is the supporting space 211, and the space corresponding to the fingers inside the "glove" is the finger supporting cavity. When the first supporting part 21 is arranged in a plate shape, the space corresponding to the first supporting part 21 is the supporting space 211, and the first supporting part 21, the finger spacer, and the elastic band (or rigid fixing structure) together define five finger supporting cavities. That is to say, the supporting space 211 (finger supporting cavity) can be an open space or a relatively closed and fixed space, and its shape needs to be judged according to the specific structure of the first supporting part 21, and no specific limitation is made here.

[0039] In some embodiments, the supporting structure 20 further includes a third supporting part 23 for supporting the patient's upper arm (posterior arm). The third supporting part 23 is arranged at one end of the second supporting part 22 away from the first supporting part 21 and is rotatably connected to the second supporting part 22.

[0040] By arranging the third supporting part 23, the hemiplegic patient upper limb fixing device 1 can play a better protective role for the affected limb. By arranging the second supporting part 22 and the third supporting part 23 to be rotatably connected, the bending angle between the upper arm and the forearm of the affected limb can be adjusted, improving the comfort of the patient's use.

[0041] It should be understood that when the patient is performing rehabilitation exercises, the exercise of pushing against the wall needs to be carried out. That is, the affected limb of the patient is horizontally lifted, the palm is attached to the wall surface, and is perpendicular to both the upper arm and the forearm, and this action is maintained for a certain period of time. For hemiplegic patients, it is difficult for the affected limb to exert force, and the elbow is prone to bend, resulting in difficulty in maintaining this action.

[0042] In this application, by arranging the second supporting part 22 and the third supporting part 23 to be rotatably connected, and arranging the first supporting part 21 and the second supporting part 22 to be rotatably connected, the hemiplegic patient upper limb fixing device 1 can assist the patient in performing the exercise of pushing against the wall.

[0043] Refer to together Figure 3 , when the patient needs to perform the exercise of pushing against the wall, the angles between the first supporting part 21, the second supporting part 22, and the third supporting part 23 can be adjusted so that the included angle between the second supporting part 22 and the third supporting part 23 is 180°, and the first supporting part 21 is perpendicular to the second supporting part 22. At this time, lift the affected limb so that the first supporting part 21 is attached to the wall surface, and the exercise of pushing against the wall can be realized. At the same time, since the included angle between the second supporting part 22 and the third supporting part 23 is 180°, the second supporting part 22 and the third supporting part 23 can play a certain supporting role for the elbow of the affected limb, preventing the elbow from bending when maintaining the action of pushing against the wall.

[0044] In some other alternative embodiments, the third supporting portion 23 may not be provided. By extending the length of the second supporting portion 22 such that its length is greater than the length of the patient's forearm, when performing the wall-pushing action, the position of the second supporting portion 22 corresponding to the patient's elbow can support the elbow and prevent the elbow from bending.

[0045] In some embodiments, the supporting structure 20 further includes a connecting portion 24. The connecting portion 24 is disposed between the first supporting portion 21 and the second supporting portion 22, and the first supporting portion 21 is rotatably connected to the connecting portion 24. The connecting portion 24 is movably disposed on the second supporting portion 22 along the extending direction of the second supporting portion 22.

[0046] By providing the connecting portion 24 that is movable along the extending direction of the second supporting portion 22, the length of the second supporting portion 22 can be extended, and thus the universality of the upper limb fixing device 1 for hemiplegic patients can be improved. The supporting structure 20 of the same size can be applicable to patients with different lengths of the affected limb. At the same time, if there is a surplus in the extended length, it can also assist the patient in performing wall-pushing action exercises.

[0047] As Figure 3 and Figure 4 shown, specifically, the second supporting portion 22 is provided with at least one guiding hole 2211 parallel to the extending direction. The connecting portion 24 includes a connecting body 241 and at least one guide rail 242. One end of the guide rail 242 is connected to the connecting body 241, and the other end is movably inserted into the guiding hole 2211. When the patient needs to extend the length of the second supporting portion 22, the connecting body 241 is pulled, and a part of the guide rail 242 is pulled out from the guiding hole 2211.

[0048] In this embodiment, the number of the guiding holes 2211 is two, and correspondingly, the number of the guide rails 242 is also two. The two guide rails 242 are arranged in parallel at intervals to improve the stability of the movable connection between the connecting portion 24 and the second supporting portion 22.

[0049] In some other alternative embodiments, the guide rail 242 and the guiding hole 2211 may not be provided. The rotatable connection between the connecting portion 24 and the second supporting portion 22 is realized through a lead screw structure, and the automatic movement of the connecting portion 24 is realized through a driving component such as a motor.

[0050] As Figure 3 shown, in some embodiments, the connecting portion 24 further includes a first rotating assembly, and the first rotating assembly is disposed on the connecting body 241 for realizing the rotatable connection between the connecting portion 24 and the first supporting portion 21.

[0051] The first rotating assembly includes a first rotating shaft 243 and a first driving member (not shown in the figure). Among them, the first rotating shaft 243 is used to drive the first supporting portion 21 to rotate. The first driving member is used to drive the rotation of the first rotating shaft 243. The first rotating shaft 243 is arranged perpendicular to the extending direction of the second supporting portion 22 and is connected to the first supporting portion 21.

[0052] Specifically, the first rotating shaft 243 is rotatably arranged on the connecting body 241 through components such as bearings and is connected to the first driving member, and rotates back and forth under the drive of the first driving member. The end of the first supporting portion 21 close to the connecting portion 24 has a protruding connecting structure, and this connecting structure is fixed on the first rotating shaft 243. When the first rotating shaft 243 rotates under the drive of the first driving member, it can drive the rotation of the first supporting portion 21, realizing the rotation of the first supporting portion 21 relative to the second supporting portion 22.

[0053] In some embodiments, the second supporting portion 22 includes a supporting body 221 and a second rotating assembly. The second rotating assembly is arranged on the supporting body 221 and at the end of the supporting body 221 away from the first supporting portion 21, and is used to realize the rotatable connection between the supporting body 221 and the third supporting portion 23.

[0054] The second rotating assembly includes a second rotating shaft 222 and a second driving member (not shown in the figure). Among them, the second rotating shaft 222 is used to drive the third supporting portion 23 to rotate. The second driving member is used to drive the rotation of the second rotating shaft 222. The second rotating shaft 222 is arranged perpendicular to the extending direction of the second supporting portion 22 and is connected to the third supporting portion 23.

[0055] Specifically, the second rotating shaft 222 is rotatably arranged on the connecting body 241 through components such as bearings and is connected to the second driving member, and rotates back and forth under the drive of the second driving member. The end of the third supporting portion 23 close to the second supporting portion 22 has a protruding connecting structure, and this connecting structure is fixed on the second rotating shaft 222. When the second rotating shaft 222 rotates under the drive of the second driving member, it can drive the rotation of the third supporting portion 23, realizing the relative rotation between the third supporting portion 23 and the second supporting portion 22.

[0056] In this embodiment, both the first driving member and the second driving member are motors, and their output shafts are respectively connected to the first rotating shaft 243 and the second rotating shaft 222. In this embodiment, the first rotating shaft 243 and the second rotating shaft 222 can rotate back and forth at a relatively large angle.

[0057] In some other alternative embodiments, the first driving member and the second driving member may also be components such as air cylinders. Taking the first driving member as an example, when the first driving member is an air cylinder, one end thereof is mounted on the connecting body 241, and the other end is disposed on the first supporting portion 21. By the telescopic driving of the air cylinder, the first supporting portion 21 can also be rotatably connected to the connecting portion 24. The same applies to the second driving member, which will not be elaborated herein.

[0058] In some other alternative embodiments, a connecting portion 24 may also be provided between the second supporting portion 22 and the third supporting portion 23. Through the relative rotation between the connecting portion 24 and the third supporting portion 23, the relative rotation between the second supporting portion 22 and the third supporting portion 23 is realized.

[0059] In some other alternative embodiments, the connecting body 241 and the guide rail 242 may not be provided. By directly disposing the first rotating assembly on the second supporting portion 22, the first supporting portion 21 can also be rotatably connected to the second supporting portion 22.

[0060] In this embodiment, the supporting body 221 and the third supporting portion 23 are both longitudinally elongated, and the cross-section perpendicular to the extending direction is arc-shaped, so as to provide a better supporting and wrapping effect on the affected limb and avoid the shaking of the affected limb.

[0061] For another example Figure 1 and Figure 2 As shown, in some embodiments, the supporting structure 20 further includes at least two fixing bands 25. Both ends of the fixing band 25 are respectively connected to both sides of the second supporting portion 22 or both sides of the third supporting portion 23 to prevent the affected limb from slipping out of the second supporting portion 22 or the third supporting portion 23.

[0062] It should be understood that both ends of the fixing band 25 are respectively connected to both sides of the second supporting portion 22 (or both sides of the third supporting portion 23), which means that they are respectively connected to both side ends in the extending direction of the second supporting portion 22 (or the third supporting portion 23), that is, respectively connected to both end portions in the arc-shaped cross-section perpendicular to the extending direction.

[0063] It should be understood that the connection points of both ends of the fixing band 25 with the second supporting portion 22 (or the third supporting portion 23) may or may not be perpendicular to its extending direction, which is not limited herein.

[0064] It should be understood that the fixing band 25 may be entirely disposed on the second supporting portion 22, or entirely disposed on the third supporting portion 23, or partially disposed on the second supporting portion 22 and partially disposed on the third supporting portion 23. When it is partially disposed on the second supporting portion 22 and partially disposed on the third supporting portion 23, the number of the fixing bands 25 on both of them may be the same or different. This is not limited herein.

[0065] It should be understood that when the number of fixing bands 25 on the second supporting part 22 (or the third supporting part 23) is two or more, they can be arranged at parallel intervals or cross each other, and no limitation is made here.

[0066] In some embodiments, the fixing band 25 can be made of an elastic material and set as an elastic band.

[0067] In some embodiments, at least one end of the fixing band 25 can be detachably connected to the second supporting part 22 (or the third supporting part 23) by setting a buckle structure or the like, so as to facilitate the patient to put on and take off.

[0068] In some embodiments, a plurality of through holes 200 are evenly spaced on the second supporting part 22 and / or the third supporting part 23 for maintaining ventilation and improving the patient's use experience.

[0069] In some embodiments, a flexible layer is attached to the inner surface of the first supporting part 21, and / or the second supporting part 22, and / or the third supporting part 23, and / or the connecting part 24 that contacts the patient, so as to improve the patient's use experience and prevent the patient's skin from being damaged.

[0070] In some embodiments, the main structures of the first supporting part 21, the second supporting part 22, the third supporting part 23 and the connecting part 24 can be made of silica gel material, which is beneficial to protecting the patient's skin and can also improve the patient's use experience.

[0071] Continue to refer to Figure 1 and Figure 2 , in some embodiments, the sling 10 includes a first belt body 11 and a second belt body 12, which are detachably connected to each other. During the wearing process, the patient does not need to perform a putting-on and sleeving action, which is convenient for operation.

[0072] Specifically, the detachable manner of the first belt body 11 and the second belt body 12 can be achieved by setting a buckle structure, and no limitation is made here.

[0073] It should be understood that the two ends of the sling 10 are respectively connected to the supporting structure 20, and they can be respectively connected to the second supporting part 22, or partially connected to the second supporting part 22 and partially connected to the third supporting part 23, etc. No limitation is made here.

[0074] Furthermore, the sling 10 can further include an adjusting member 13, and the free end of one of the first belt body 11 and the second belt body 12 is movably threaded through the adjusting member 13 so that the length of the sling 10 is adjustable. By adjusting the length of the sling 10, the angle between the forearm and the upper arm can be changed, the bending rotation of the elbow joint can be realized, and then the relevant muscles can be driven to rotate, which is beneficial to rehabilitation.

[0075] It should be understood that the adjustment member 13 can be selected from the existing shoulder strap adjustment member on the backpack, which is formed with at least two parallel adjustment holes, and the free ends of the first belt body 11 or the second belt body 12 are sequentially inserted into the two adjustment holes. During normal use, the belt body (the first belt body 11 or the second belt body 12) inserted on the adjustment member 13 can be kept in place under the action of tension or friction. When the patient needs to adjust the length of the sling 10, the length of the sling 10 can be adjusted by pulling the free end so that the tension is greater than the friction.

[0076] The adjusting member 13 can also be another existing shoulder strap adjusting member on a backpack, which includes a threading portion and a positioning portion (not shown in the figure), and the positioning portion is rotatably arranged on the threading portion, and the threading portion can be threaded with a belt body. During normal use, the positioning portion is buckled on the threading portion, and can achieve an interference fit with the threading portion and the belt body, thereby achieving the belt body and the adjusting member 13 to maintain positioning. When the patient needs to adjust the length of the sling 10, the positioning portion can be rotated so that the positioning portion, the threading portion and the belt body are no longer in an interference fit. At this time, the belt body can be pulled to adjust the length of the sling 10. No specific limitation is made here.

[0077] It should be understood that the “free end” refers to the end of the first belt body 11 or the second belt body 12 that is not connected to the supporting structure 20 .

[0078] When the patient is using the sling, the patient can adjust the length of the entire sling 10 by pulling the free end of the first belt body 11 or the second belt body 12 through the adjusting member 13 without seeking help from others.

[0079] It can be understood that the above embodiments only express some implementation methods of the present application, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application; it should be pointed out that for ordinary technicians in this field, without departing from the concept of the present application, the above embodiments or technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the present application, that is, the embodiments described in "some embodiments" can be freely combined with any of the above and below embodiments; therefore, all equivalent changes and modifications made to the scope of the claims of the present application should fall within the scope of the claims of the present application.
