Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation assistive devices, and in particular to a shoulder-free assistive device. Background Art

[0002] The shoulder is one of the most complex and flexible joints in the human body. It is composed of the clavicle, scapula and humerus, and together with muscles, joints, ligaments and nerves, it forms a complex structure that provides stability and a wide range of movements. The spine is the axial skeleton of the human body and the pillar of the body. It has functions such as weight bearing, shock absorption, protection and movement. The shoulder is connected to the thorax through the clavicle. The medial end of the clavicle forms the sternoclavicular joint with the sternum, and the lateral end connects with the scapula to form the acromioclavicular joint. The scapula is connected to the arm through the humerus. The upper angle of the scapula is connected to the cervical spine through the levator scapulae, and the lower angle is connected to the spine through the latissimus dorsi and other muscles.

[0003] In modern life, carrying things with you has become a daily necessity, and the things you carry are external loads on the human body. Since the shoulder is the part where the upper limbs of the human body connect to the trunk, whether you carry things by hand or on your shoulders, the external load is mainly transmitted directly and indirectly from the shoulder to the spine and surrounding tissues; ultimately, the weight of the items is transmitted to the pelvis through the spine and surrounding tissues, and then to the ground from the lower limbs. At this time, the load on the trunk is the sum of the body weight, muscle tension and external load above a certain section of the spine. The shoulders and spine jointly support the upper part of the human body and maintain the body's posture and motor function. However, due to the long-term existence of external loads, or excessive external loads, it will cause pressure and damage to the shoulders and spine, especially for patients with shoulder injuries, low back pain, scoliosis and other shoulder and spinal structure lesions, they need to minimize the load on the shoulders and spine.

[0004] At present, in the invention patent with patent number CN113303959B, named a spinal load-free assistive device, an assistive device that can reduce the weight of the human spine is disclosed; although the assistive device can reduce the weight of the human spine, it cannot reduce the weight of the human shoulder, so it is not ideal for patients with shoulder lesions and is not conducive to the rehabilitation of the patient's shoulder. In addition to the above, there are also existing technologies that add shoulder straps to backpacks to alleviate the problem of shoulder weight, but this method only changes the force position of the shoulder and does not fundamentally reduce the weight of the shoulder. Therefore, how to reduce the weight of the shoulders and spine when carrying items is a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of this, an embodiment of the present invention provides a shoulder load-free assistive device to eliminate or improve one or more defects existing in the prior art.

[0045] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0046] Figure 1 FIG. 1 is a schematic diagram of the structure of a shoulder-unloading auxiliary device in one embodiment of the present invention. Figure 1 As shown in FIG. 1 , the shoulder-loading assistive device at least comprises a waist belt 100, a spine support member 200, a bionic shoulder 300, a connecting member and a load-bearing portion 700, and the overall structure of the shoulder-loading assistive device is similar to that of a backpack. Figures 2 to 6 It can be seen that the bionic shoulder 300 is specifically located at the shoulder position of the human body, the spine support 200 is located at the back position of the human body, and the two connecting parts are similar to the two shoulder straps of a backpack and are located at the chest position of the human body.

[0047] The waist belt 100 is used to wrap around the outside of the iliac crest, the posterior superior iliac spine and the anterior superior iliac spine of the human body, and the waist belt 100 is used to be fixed on the waist of the human body. A waist support 110 is provided in the middle of the rear side of the waist belt 100. The spine support is used to be arranged on the back of the human body along the height direction of the human spine, and the bottom end of the spine support 200 is connected to the waist support 110. The bionic shoulder 300 includes a rear shoulder 310 arranged on the rear side of the neck along the shoulder width direction of the human body and side shoulders 320 arranged on the left and right sides of the neck along the front-back direction of the human body. The two side shoulders 320 are used to be arranged above the left acromion and the right acromion respectively, and the rear shoulder 310 of the bionic shoulder 300 is connected to the top of the spine support. The connecting member includes a first connecting member and a second connecting member for being arranged at the front chest of a human body, wherein the first end of the first connecting member and the first end of the second connecting member are respectively connected to the two side shoulders 320, and the second end of the first connecting member and the second end of the second connecting member are both connected to the waist belt 100. The load-bearing part 700 is arranged on the side of the spinal support member away from the human body, and the load-bearing part 700 is connected to both the bionic shoulder 300 and the spinal support member 200, so as to transfer the gravity of the load-bearing part 700 to the human pelvis through the bionic shoulder 300 and the spinal support member 200.

[0048] In the above embodiment, the waist belt 100 as a whole can form a closed oval structure to cover the entire waist of the human body; in order to make the waist belt 100 easy to wear, the main part of the waist belt 100 can be made of soft material. In this case, the waist belt 100 as a whole can be an oval waist belt, which can be directly put from the head down to the waist of the human body when worn; in addition, the waist belt 100 can also be designed as a long strip structure as a whole, and the waist belt 100 can be fixed to the waist of the human body by zippers or Velcro at both ends of the waist belt 100. It can be understood that the structural shape and fixing method of the waist belt 100 are not specifically limited, as long as it can be fixed to the waist of the human body. Figure 2 and Figure 3 As shown, the waist support member 110 is located at the center of the back side of the waist belt 100. The waist support member 110 is made of a hard material, such as plastic, aluminum alloy, titanium alloy, etc. The waist support member 110 is connected to the bottom end of the spine support member 200. In addition, in order to improve the strength of the waist belt 100, a hard reinforcement member can be further arranged at the position corresponding to both sides of the waist of the human body. The material used for the hard reinforcement member is plastic, aluminum alloy, titanium alloy, etc.

[0049] The spine support member 200 is used to be arranged on the back of the human body along the height direction of the spine. The spine support member 200 and the waist support member 110 of the waist belt 100 can be connected by a plug-in connector. The number of the spine support member 200 can be one or more. When the number of the spine support member is one, such as Figure 3 As shown in FIG. 1 , the top and bottom ends of the spinal support member 200 are connected to the middle of the bionic shoulder 300 and the middle of the waist support member 110 respectively; when the number of the spinal support members is two, as shown in FIG. Figure 2 As shown, the two spinal support members 200 may be disposed bilaterally symmetrically relative to the mid-sagittal plane.

[0050] Exemplarily, the spinal support 200 is a rod-shaped structure with a curvature, and the height and curvature of the spinal support 200 can be customized based on the spinal curvature and height of the human body; in this embodiment, the customized configuration of the height and curvature of the spinal support 200 can better improve the adaptability to the user; and it can be understood that in some other embodiments, the spinal support 200 of the shoulder unloading aid can also be set to a fixed length and a fixed curvature, and the shoulder unloading aid of this structure can also achieve the purpose of transferring the shoulder weight to the human pelvis through the bionic shoulder 300 and the spinal support 200, but the effect of repairing the curvature lesions of the human spine is reduced.

[0051] Figure 7 and Figure 8They are respectively a front view and a side view of a spinal support member 200 in one embodiment of the present invention. The front view of the spinal support member can also be understood as a schematic projection diagram of the spinal support member on the coronal plane, and the side view can be understood as a schematic projection diagram of the spinal support member on the sagittal plane; Figure 7 and Figure 8 As shown, the spinal support 200 in this embodiment is bent toward the left side at the top position. The spinal support 200 of this structure can not only meet the needs of different human bodies for reducing shoulder load, but also for some users with curved spines, it is beneficial to the recovery of their spines or the prevention of worsening spinal deformity; for example, the spinal support 200 is highly adapted to users whose spines are curved to the left or right. In addition, the spinal support 200 can be 30mm wide, 400mm high, and 10mm thick. Furthermore, the spinal support 200 is made of hard materials, such as plastics, aluminum alloys or titanium alloys; in addition, the spinal support 200 can be processed in an integrated manner.

[0052] In some embodiments, the projection shape of the rear shoulder 310 of the bionic shoulder 300 on the horizontal plane is an arc shape with the middle convex toward the back of the human body, and the projection shape of the rear shoulder 310 on the coronal plane is a wave shape with multiple peaks, and the bionic shoulder 300 is a bilaterally symmetrical structure relative to the midsagittal plane. Figure 4 The bottom-to-top direction in Figure 2 and Figure 3 As shown, the bionic shoulder 300 has a crest at a position close to the left acromion and the right acromion, respectively, and the two crests are located on the left acromion and the right acromion of the human body, respectively. Further, in order to improve the support stability of the bionic shoulder 300, the bionic shoulder 300 can be made of a hard material, such as plastic, aluminum alloy, titanium alloy, etc.

[0053] exist Figure 3 In the schematic diagram shown, there is one spinal support member, and the number of wave crests of the rear shoulder 310 is three, and the top end of the spinal support member is connected to the middle wave crest of the rear shoulder 310, and the bottom end of the spinal support member is connected to the middle of the waist support member 110. Figure 2In the schematic diagram shown, there are two spinal support members, and at this time, there are two wave crests in the rear shoulder 310, and the top ends of the two spinal support members are respectively connected to the two wave crests, and the bottom ends of the two spinal support members are respectively connected to the left and right ends of the top of the waist support member 110. The projection shape of the bionic shoulder 300 in this embodiment on the coronal plane can be regarded as an "M" shape. Based on the above embodiment, it can be seen that the number of spinal support members and the number of wave crests on the rear shoulder 310 are not specifically limited. In order to ensure the uniformity of the force of the bionic shoulder 300 and the spinal support member, the bionic shoulder 300 is symmetrically arranged with respect to the median sagittal plane, and two or more spinal support members are also symmetrically arranged with respect to the median sagittal plane. In addition, the bottom end of the spinal support member is connected to the top end of the waist support member 110, which can also be understood as the bottom end of the spinal support member being extended to the posterior superior iliac spine.

[0054] In some embodiments, the top of the spinal support member and the bionic shoulder 300 may be connected via a quick-connect connector. For example, a T-shaped pipe interface may be provided at the location where the bionic shoulder 300 is connected to the spinal support member 200; Figure 3 As shown, the transverse pipe section of the T-shaped pipe interface is sleeved on the bionic shoulder 300, and the top of the spinal support is inserted into the vertical pipe section of the T-shaped pipe interface to achieve the connection between the bionic shoulder 300 and the spinal support. It can be understood that the bionic shoulder 300 and the spinal support are connected by the T-shaped pipe interface only as an example. In addition, the bionic shoulder 300 and the spinal support can also be connected by other methods.

[0055] In addition, the two side shoulders 320 of the bionic shoulder 300 are respectively located on the left acromion and the right acromion of the human body. Figure 4 As shown, the front end portions of the two side shoulders 320 are located at the front side of the left shoulder peak and the right shoulder peak; in this embodiment, the front end of the side shoulder 320 refers to Figure 4 The lower end of the lateral shoulder 320 in the figure, and the front side of the left shoulder peak and the right shoulder peak refers to the front side of the human body, that is, Figure 4 The lateral shoulder 320 extends from the rear shoulder position of the human body roughly along the direction of the middle muscle bundle of the trapezius muscle to the left acromion and the right acromion. The lateral shoulder 320 is specifically located 5 to 10 cm inside the left acromion and the right acromion, wherein the inside of the left acromion and the right acromion refers to the side of the left acromion and the right acromion close to the head. In addition, the position of the two lateral shoulders 320 can also be understood as being located above the trapezius muscle at the corresponding position (refer to Figure 5 ).

[0056] In addition, the first connector and the second connector can be cross-arranged at the front chest of the human body, and the second end of the first connector and the second end of the second connector are respectively connected to the positions of the waist belt 100 corresponding to the left and right waist parts of the human body; in this embodiment, the two connectors cross and extend downward from the front ends of the two side shoulders 320 until they extend to the vicinity of the waist belt 100, and the two connectors are symmetrically arranged with respect to the midsagittal plane. Figure 6 , the top ends of the first connector and the second connector are connected to the front end of the left shoulder and the front end of the right shoulder respectively, and the bottom ends of the first connector and the second connector are connected to the right waist position and the left waist position of the waistband 100 respectively, and this structure realizes the cross setting of the two connectors. It can be understood that the structure of setting the two connectors to be cross is only a preferred embodiment. In other embodiments, the top end and the bottom end of the first connector can also be connected to the left shoulder and the left waist position respectively, and the top end and the bottom end of the second connector can also be connected to the right shoulder and the right waist position respectively. Exemplarily, the first connector and the second connector can be specifically a strap.

[0057] In addition, in order to facilitate the wearing and taking off of the first connector and the second connector and to adjust the length, the first connector and the second connector are further provided with a first connecting buckle 430 for adjusting the length and plugging. The first connecting buckle 430 is exemplified by a plug buckle, a D-shaped buckle, etc. Figure 6 As shown, the first connecting buckle 430 can be specifically arranged at a position of the connecting member close to the waist belt 100. At this time, the top of the connecting member (including the first connecting member and the second connecting member) can be fixed to the side shoulder 320 of the bionic shoulder 300 by a detachable connection or a non-detachable connection. Similarly, the bottom of the connecting member can be fixed to the waist belt 100 by a detachable connection or a non-detachable connection. When wearing the shoulder-loading auxiliary device, the first connecting buckle 430 on the first connecting member and the second connecting member can be opened first. After the shoulder-loading auxiliary device is put on in place, the first connecting buckle 430 on the first connecting member and the second connecting member can be further plugged in and adjusted to a suitable tightness.

[0058] In addition, when the hard reinforcements 120 are provided at positions of the waistband 100 corresponding to both sides of the human waist, the bottom ends of the first connector and the second connector can be specifically connected to the hard reinforcements 120 on both sides of the waistband 100 .

[0059] In some other embodiments, the spinal support 200 can be configured in a personalized manner. For example, when the human spine is bent, the spinal support 200 is bent in a direction consistent with the bending direction of the human spine, or the spinal support 200 is bent in a direction opposite to the bending direction of the human spine. In this embodiment, when part of the user's spine is bent, in order to prevent the heavy object carried from increasing the spinal curvature or causing damage to the bent spine, the spinal support of the shoulder-unloading aid can also be set to a structure similar to the bent spine. The shoulder-unloading aid with this structure is conducive to the rehabilitation of the bent spine. Exemplarily, based on the axis of the midsagittal plane, when part of the user's spine is bent to the left by 30 degrees, the part of the spinal support corresponding to the spinal curvature can be set to be less than 30 degrees to the left, or less than or equal to 30 degrees to the right; it is easy to understand that when the spinal support 200 of this structure transmits gravity to the human pelvis, the force of the spinal support 200 can compensate for the bent spine, thereby reducing the curvature of the spine and facilitating the recovery of the spine. In addition, it should be understood that the spinal support member 200 is designed to be highly compatible with the human spine in order to further achieve the effect of restoring the curved spine on the basis of reducing the load on the shoulders and spine, which belongs to the personalized configuration of the spinal support rod. In order to make the processed shoulder-free assistive device suitable for different users, the spinal support member of the shoulder-free assistive device can also be directly designed as Figure 2 and Figure 3 The structure shown in .

[0060] Exemplarily, the load-bearing part 700 may include an accordion bag 710 for accommodating articles, and the shoulder unloading aid transfers the gravity of the articles in the accordion bag 710 to the human pelvis through the bionic shoulder 300 and the spinal support. In this embodiment, the heavy object is placed in the accordion bag 710, and the bionic shoulder 300 is connected to the top of the accordion bag 710; in this embodiment, there are multiple ways to connect the top of the accordion bag 710 with the bionic shoulder 300, for example, the top of the accordion bag 710 may be provided with a plurality of through holes for passing the bionic shoulder 300 at intervals, or a hem covering the bionic shoulder 300 may be directly provided at the top of the accordion bag 710 along the width of the accordion bag 710, etc.

[0061] For users with curved spines, in order to further facilitate the recovery of the curved spine, heavy objects can be further placed on the load-bearing portion 700 of the shoulder unloading aid to facilitate the recovery of the curved spine. Furthermore, there are multiple accordion bags 710, and the multiple accordion bags 710 are stacked in a direction away from the back of the human body, and the bottom ends of at least some of the accordion bags 710 are stepped in the height direction of the spine support 200. Exemplarily, the sizes of the multiple accordion bags 710 can be the same, and in this case, the height of some of the multiple accordion bags 710 is between 1.5 and 2.0. Figure 1In the figure shown, it gradually decreases from right to left, that is, in this part of the accordion bags, the bag opening and the bag bottom of the accordion bag 710 located on the far right are the highest, and the bag opening and the bag bottom of the accordion bag 710 located on the far left are the lowest. Among them, the accordion bag 710 on the far right is also the accordion bag 710 closest to the human back, and the accordion bag 710 on the far left is also the accordion bag 710 farthest from the human back.

[0062] In a specific embodiment, if Figure 1 As shown, the shoulder-free load assistive device may include two stepped accordion bag groups, each stepped accordion bag group includes three accordion bags 710, the three accordion bags 710 in each stepped accordion bag group are of the same size, and the bag openings and bag bottoms of the three accordion bags 710 are respectively arranged in a stepped downward direction from right to left; wherein, the positions of the accordion bags in the two stepped accordion bag groups correspond to each other, such as the height of the rightmost accordion bag 710 of the left stepped accordion bag group is the same as the height of the rightmost accordion bag 710 of the right stepped accordion bag group, and the height of the leftmost accordion bag 710 of the left stepped accordion bag group is the same as the height of the leftmost accordion bag 710 of the right stepped accordion bag group, so that the six accordion bags 710 of the two stepped accordion bag groups are arranged in pairs at each height. In this embodiment, the accordion bags 710 arranged in three steps correspond to multiple parts of the spine at different heights. For example, when the uppermost part of the spine is bent, the weight can be placed in the innermost accordion bag 710 in one of the stepped accordion bag groups, and when the lowermost part of the spine is bent, the weight can be placed in the outermost accordion bag 710 in one of the stepped accordion bag groups; the inner and outer sides are defined relative to the back of the human body, for example, the inner side represents the side close to the back of the human body, and the outer side represents the side away from the back of the human body.

[0063] Furthermore, each accordion bag 710 includes a left half pocket and a right half pocket, and the left half pocket and the right half pocket are of different sizes. This structure is to selectively place a heavy object on the left side or the right side of the back to compensate for the curvature of the spine. In the above-mentioned specific embodiment, three groups of accordion bags of different heights match the three bending positions of the spine, and the accordion bags are set to have different sizes of the left half pocket and the right half pocket to match the two bending directions of the spine; thus, when the spine is bent at any height in any direction, a heavy object can be placed in the left half pocket or the right half pocket of the corresponding accordion bag to better compensate for the curvature of the spine.

[0064] exist Figure 1 In the embodiment shown, the stepped accordion bag group close to the back of the human body can be set to a structure in which the left half pocket is larger than the right half pocket, while the stepped accordion bag group far from the back of the human body can be set to a structure in which the left half pocket is smaller than the right half pocket. This allows heavy objects to be placed in various positions on the back, such as high left, middle left, low left, high right, middle right, and low right.

[0065] In other embodiments, the shoulder-unloading aid may further include a back pad 600, which is disposed on a side of the spinal support 200 close to the back of the human body, and the back pad 600 is used to fit the back of the human body. The back pad 600 is a soft back pad 600, which fits the back to improve the wearing comfort of the shoulder-unloading aid. Specifically, the back pad 600 can be fixed on the spinal support or the load-bearing part 700, and the fixing method of the back pad 600 is not limited, as long as it is ensured that the back pad 600 fixed on the spinal support or the load-bearing part 700 can fit the back of the human body.

[0066] Furthermore, the shoulder unloading aid further comprises two underarm connectors 500, which are used to be arranged at the underarm part of the human body, the first ends of the two underarm connectors 500 are connected to the spinal support member, and the second ends of the two underarm connectors 500 are connected to the first connector 410 and the second connector 420 respectively. Figure 6 As shown, when the shoulder unloading aid is worn in place, the underarm connector 500 is located at the underarm part of the human body. In addition, the underarm connector 500 can be set to a length-adjustable structure similar to the first connector 410 and the second connector 420. For example, the underarm connector can be provided with a second connector buckle 510 for plugging and adjusting the length. The second connector buckle 510 is exemplified by a plug buckle, a D-shaped buckle, etc. The second connector buckle 510 can be specifically set at a position of the underarm connector close to the first connector or the second connector; the two underarm connectors can be adjusted in tightness through the connector buckle. In an embodiment in which a higher segment of the spine (i.e., a segment of the spine close to the armpit height) is bent to the left, a heavier weight can be placed in the right half pocket of the accordion bag 710 which is lower than the height of the bent segment. At this time, the corresponding tightening of the left underarm connector can be more conducive to the recovery of the curved spine; similarly, in an embodiment in which a higher segment of the spine (i.e., a segment of the spine close to the armpit height) is bent to the right, a heavier weight can be placed in the left half pocket of the accordion bag 710 which is lower than the height of the curved segment of the spine that is bent to the left. At this time, the corresponding tightening of the right underarm connector can apply a three-point force correction to the curved spine in the horizontal direction and reduce the length of the rotation lever arm in the vertical direction, which is beneficial to the load-bearing of the curved spine and prevents the aggravation of spinal deformity.

[0067] It can be understood that the main materials of the accordion bag 710, back pad 600, waist belt 100, etc. can all be made of soft fabric materials such as nylon, Oxford cloth, canvas, etc., and the connection between the various components can adopt the zippers, plug buckles, adjustment buckles and other connection methods commonly used on existing backpacks.

[0068] In the above embodiment, the bionic shoulder is a curved rod located between the upper and rear parts of the left and right acromion, which replaces the human shoulder to bear the pressure of external weight and transfers the pressure to the pelvis through the spinal support, which not only reduces the burden on the shoulder, but also reduces the burden on the spine. Fig. 9 : is a schematic diagram of force analysis of a shoulder-loading relief device in an embodiment of the present invention. Based on the schematic diagram of force analysis, it can be concluded that the force and moment of the shoulder-loading relief device as a whole are balanced, that is, ∑F=F 支持 +G+F 抗扭1 +F 抗扭2 +F 前 +F 后 =0,∑M=M 后 +M 前1 +M 前2 =0; therefore, the shoulder load-relieving aid disclosed in the present application has a better effect in reducing the burden on the shoulders.
