Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation medicine, and in particular to a shoulder fixation device for orthopedic rehabilitation. Background Art

[0002] The human shoulder is composed of the scapula, clavicle and humerus. The connection between the scapula and the humerus is called the glenohumeral joint. The glenohumeral joint is specifically composed of the glenoid cavity of the scapula and the humeral head of the humerus. The glenoid cavity is a shallow and small socket-like structure, and the humeral head is a large and round spherical structure. When the above two are combined, the glenoid cavity can only accommodate about a quarter of the humeral head. Therefore, the shoulder joint has a large range of motion but poor stability. Shoulder dislocation or fracture is prone to occur clinically. When shoulder dislocation occurs, a shoulder brace is usually used to fix the shoulder after treatment to reduce the stress on the shoulder joint and prevent it from dislocating again.

[0003] A shoulder brace is usually composed of a chest strap, a main body and an upper arm strap. When wearing the shoulder brace, the upper arm strap needs to be fixed first, and then the shoulder brace main body is pulled upwards, and the chest strap is connected to the shoulder brace main body at the same time. Since the lifting of the shoulder brace main body and the fixing of the chest strap to the main body need to be performed at the same time, existing patients cannot wear the shoulder brace by themselves and can only rely on family members or caregivers to put on the shoulder brace for the patients, which makes the existing shoulder brace inconvenient to use. Summary of the Invention

DETAILED DESCRIPTION

[0026] Among them, the accompanying drawings are only for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limiting the present invention. In order to better illustrate the embodiments of the present invention, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the dimensions of actual products. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the accompanying drawings.

[0027] It is worth noting that the shoulder rest shown in the attached figure is a left shoulder rest, which is suitable for patients with left shoulder dislocation. The following examples will be given using patients with left shoulder dislocation as an example.

[0028] A shoulder fixation device for orthopedic rehabilitation, see Figure 1-Figure 5 , including: a main body 1, an upper arm portion 101 is provided on the main body 1, an upper arm band 2 is fixed to the upper arm portion 101, a fastening belt 3 is fixed to the main body 1, a connecting buckle 4 is fixed to the position of the upper arm portion 101 away from the upper arm band 2, and the connecting buckle 4 contacts and cooperates with the upper arm band 2; an airbag 5 is fixed to the upper arm band 2 to provide support for the patient's upper arm; a velvet surface 6 is fixed to a position on the upper arm band 2 close to the airbag 5, and a hook surface 7 is fixed to the position of the upper arm band 2 away from the airbag 5, and the hook surface 7 is in contact with the upper arm band 2. The suede surface 6 is in contact and fit; the connecting piece 8 is fixed to the end of the fastening belt 3 away from the main body 1; the sleeve 9 is fixed to the main body 1, and the sleeve 9 is fixed with a drawstring 10, and a sliding sleeve 11 is fixed to the main body 1 near the sleeve 9; the tightening piece 12 is installed on the main body 1, and the drawstring 10 passes through the connecting piece 8 and the sliding sleeve 11 and is connected to the tightening piece 12 for winding up the drawstring 10; the main body 1, the upper arm strap 2 and the fastening belt 3 are all made of polyester-cotton blended material, so that the above three have both elasticity and breathability.

[0029] In the above scheme, the fixing action and the lifting action of the shoulder support are carried out separately, so as to facilitate the patient to wear the shoulder support by himself; the chest strap of the existing shoulder support is usually a single elastic strap. Since one end of the chest strap is located on the patient's left shoulder, the other end of the chest strap needs to be passed around the patient's right chest and fixed to the shoulder support. At the same time, in order to reduce the patient's discomfort, the chest strap is usually made of a wide elastic strap, which makes the upper and lower sides of the chest strap around the patient's upper body have different lengths, which easily leads to different tightening forces on the patient on the upper and lower sides of the chest strap, which also causes discomfort to the patient while wearing the shoulder support; the polyester-cotton blended material of the main body 1, upper arm straps 2 and 3 makes the above three both elastic and breathable , reducing the discomfort felt by the patient during wearing; an air hole can be provided on the airbag 5, and the airbag 5 can be inflated with a tool after wearing is completed, so that the airbag 5 can maintain slight abduction of the upper limb; the hook surface 7 and the velvet surface 6 cooperate to form a Velcro, and there can be a distance between the hook surface 7 and the end of the upper arm strap 2, which is convenient for the patient to pull the upper arm strap 2 so that the hook surface 7 loses contact with the velvet surface 6; by replacing the fastening belt 3 on the traditional shoulder support and the fixing method therebetween with Velcro, the tightness of the fastening belt 3 can be adjusted directly by rotating the tightening piece 12 when the action of pulling the main body 1 upward is completed, so that the patient can wear the device by himself.

[0030] The tightening member 12 is an existing component (similar to the existing knob-type shoelace tightening system). The drawstring 10 can be wound up by rotating the tightening member 12, and the drawstring 10 can be released with one click by pressing the tightening member 12; the sleeve 9 and the sliding sleeve 11 are both fixed to the main body 1 by sewing, and the sleeve 9 and the drawstring 10 can be fixedly connected by sewing; when the shoulder support of this device rewinds the drawstring 10 through the tightening member 12, the drawstring 10 moves by pulling the fastening belt 3 through the connecting member 8. When the tightening force of the fastening belt 3 on the patient reaches an appropriate value, the tightening member 12 is stopped, and then the patient feels whether the tightening force on the upper and lower sides of the fastening belt 3 is consistent. If not, the position of the connecting member 8 on the drawstring 10 is changed, thereby changing the pulling force of the drawstring 10 on the upper and lower sides of the connecting member 8, so that the tightening force of the upper and lower sides of the fastening belt 3 on the patient tends to be consistent, thereby improving the comfort of the patient while wearing the shoulder support.

[0031] See also Figure 4 A first shielding portion 401 and a second shielding portion 402 are provided on the connecting buckle 4. The first shielding portion 401 and the second shielding portion 402 are not at the same height. In the horizontal direction, the sum of the lengths of the first shielding portion 401 and the second shielding portion 402 is greater than the length of the connecting buckle 4.

[0032] In the above scheme, it is intended to facilitate the connection between the upper arm strap 2 and the connecting buckle 4; the connecting buckle 4 is U-shaped, and the corners on the upper side of the first shielding part 401 can be provided with an inclined surface to facilitate guiding the upper arm strap 2 into the connecting buckle 4; the action of the upper arm strap 2 on the traditional shoulder support passing through the connecting buckle 4 is transformed into the action of the upper arm strap 2 sliding into the connecting buckle 4, which ensures the firmness of the cooperation between the hook surface 7 and the velvet surface 6 on the upper arm strap 2, while reducing the difficulty of operation, making it easier for patients to operate by themselves.

[0033] See also Figure 5 , there is friction between the sliding sleeve 11 and the pull rope 10.

[0034] In the above solution, the purpose is to provide resistance to the winding of the pull rope 10 and ensure the tightness of the winding of the pull rope 10 by the tightening member 12.

[0035] See also Figure 5 , the number of the sliding sleeves 11 is greater than or equal to two, and there is a gap between adjacent sliding sleeves 11.

[0036] In the above scheme, the friction between the sleeve 11 and the pull rope 10 is used to provide pre-tensioning for the pull rope 10; in this article, the number of the sleeves 11 is two, and the gap between the two sleeves 11 is larger than the width of the patient's fingers; before rotating the tightening member 12 to tighten the pull rope 10, the pull rope 10 between the two sleeves 11 is hooked out by the fingers to pre-tighten the fastening belt 3, and the friction between the sleeve 11 and the pull rope 10 is used to maintain the tightening state of the fastening belt 3.

[0037] See also Figure 5 , further comprising: a plurality of first elastic strips 13 , all of which are fixed to the main body 1 , and the first elastic strips 13 are used to maintain the shape of the main body 1 .

[0038] See also Figure 6 and Figure 7 , also includes: two edge elastic strips 14, both fixed to the upper arm portion 101, and a plurality of groove elastic strips 15 are fixed to the upper arm portion 101; a second elastic strip 16, fixed to the upper arm band 2, and an elastic sheet 17 is fixed to the upper arm band 2.

[0039] In the above scheme, the first elastic strip 13 is used to maintain the shape of the upper part of the main body 1, so that the patient can pull the main body 1 upward by himself; at the same time, the edge elastic strip 14, the groove elastic strip 15, the second elastic strip 16 and the elastic sheet 17 are used to maintain the shape of the lower part of the shoulder support, so as to adjust the position of the shoulder support; the number of the first elastic strips 13 is determined according to the area of the main body 1, and the number of the first elastic strips 13 in this article is two; the first elastic strip 13, the second elastic strip 16 and the elastic sheet 17 are made of flexible rubber material, and the second elastic strip 16 and the elastic sheet 17 are used to maintain the shape of the upper arm band 2, prevent the upper arm band 2 from folding, and keep the upper arm band 2 straight in a free state, so that the patient can pull the upper arm band 2 to cooperate with the connecting buckle 4; the edge elastic strip 14 and the groove elastic strip 15 are made of hard rubber material, which is used to maintain the shape of the upper arm part 101.

[0040] See also Figure 6 and Figure 7 , further comprising: a traction ring 171 fixedly connected to the upper arm portion 101 , and the second elastic strip 16 and the elastic sheet 17 are both fixedly connected to the adjacent edge elastic strip 14 .

[0041] In the above scheme, the purpose is to prevent the upper arm band 2 from being folded between the upper arm portion 101 and the patient's left arm when wearing the main body 1; the traction ring 171 can be a rope with both ends fixed to the upper arm portion 101, and the traction ring 171 can assist the patient in maintaining the position of the upper arm portion 101 unchanged during the process of moving the upper arm band 2 to cooperate with the connecting buckle 4.

[0042] See also Figure 6-Figure 8 , and also includes: two fastening ropes 18, both fixed to the two edge elastic strips 14; a main fastener 19, fixed to the fastening rope 18 on one side, and a plurality of fastening bevel grooves 191 are provided in the main fastener 19, and the fastening rope 18 on the other side is fixed to a secondary fastener 20, and the secondary fastener 20 is provided with a fastening tooth 201, and the fastening tooth 201 is limitedly matched with the fastening bevel groove 191.

[0043] In the above scheme, the purpose is to adjust the tightening force of the upper arm 101 and the upper arm band 2 on the patient's left arm; two grooves are provided on the groove elastic strip 15, and the grooves of the groove elastic strip 15 are used to provide a moving path for the adjacent fastening rope 18; the secondary fastener 20 is made of elastic material; the fastening bevels 191 can be set to two groups, and the number of fastening bevels 191 in each group is several; the fastening teeth 201 can be set to two, so as to improve the force uniformity of the main fastener 19 and the secondary fastener 20; by changing the relative position of the main fastener 19 and the secondary fastener 20, the two fastening ropes 18 are tightened, so that the distance between the multiple groove elastic strips 15 and the edge elastic strip 14 is reduced, and the circumference surrounded by the upper arm 101 and the upper arm band 2 is reduced, thereby increasing the tightening force of the upper arm 101 position on the patient's left arm.

[0044] See also Figure 8 and Figure 9 , and also includes: a locking member 21, which is limitedly slidably connected to the auxiliary fastener 20, and a locking portion 211 and an unlocking portion 212 are provided on the locking member 21, the locking portion 211 is limitedly matched with the fastening tooth 201, and the unlocking portion 212 is squeezed and matched with the fastening tooth 201.

[0045] In the above scheme, the locking member 21 is intended to lock and release the relative position of the main fastener 19 and the secondary fastener 20; the locking member 21 relies on the friction between it and the secondary fastener 20 to maintain stability; the width of the locking portion 211 is equal to the distance between the two fastening teeth 201. When the locking portion 211 and the two fastening teeth 201 are at the same height, the two fastening teeth 201 cannot move towards each other, thereby locking the relative position of the main fastener 19 and the secondary fastener 20; when the locking member 21 moves downward relative to the secondary fastener 20, the unlocking portion 212 gradually contacts the two fastening teeth 201 and squeezes the two fastening teeth 201 to move towards each other, so that the fastening teeth 201 release the restriction on the adjacent fastening bevel 191.

[0046] When wearing this device, the patient first passes the right arm and head through the "ring" composed of the main body 1, the fastening belt 3 and the pull rope 10, and then places the main body 1 on the left shoulder. At this time, the two ends of the fastening belt 3 are respectively located on the front and back sides of the patient. Then the patient adjusts the position of the fastening belt 3 so that the fastening belt 3 contacts the lower part of the right armpit. At this time, the fastening belt 3 and the pull rope 10 located on the front side of the patient are in a relaxed state. The patient continues to adjust the position of the fastening belt 3, and pulls the upper end of the pull rope 10, and pulls the pull rope 10 over a sliding sleeve 11. Finally, the pull rope 10 and the fastening belt 3 are maintained in the adjusted position, and the pull rope 10 between the two sliding sleeves 11 is in a relaxed state. In this way, the adjusted positions of the fastening belt 3 and the pull rope 10 are fixed, which is convenient for subsequent tightening of the fastening belt 3 and the pull rope 10.

[0047] After the patient has completed the steps of adjusting the fastening belt 3, he hooks the traction ring 171 with his right thumb and uses his right index finger to pull the upper arm belt 2 from the back of the left arm to the front, and wraps the upper arm belt 2 to the inside of the left arm. Then, the upper arm belt 2 is clamped into the connecting buckle 4, and the hook surface 7 is fitted with the velvet surface 6 (at this time, the tightening force of the upper arm belt 2 and the upper arm part 101 on the patient's left arm is small). The patient presses the main fastener 19 into the secondary fastener 20, and the fastening teeth 201 contact the adjacent fastening bevels 191 in turn, and the main fastener 19 is pushed into the secondary fastener 20. Move, pull the fastening rope 18 to move, the fastening rope 18 pulls the edge elastic strip 14 to move, so that the gap between the edge elastic strip 14 and the multiple groove elastic strips 15 is reduced, thereby increasing the tightening force of the upper arm band 2 and the upper arm part 101 on the patient's left arm. After the tightening force reaches an appropriate size, the patient stops pressing the main fastener 19 and the secondary fastener 20, and pushes the locking piece 21 into the secondary fastener 20, so that the locking part 211 is at the same height as the fastening tooth 201, and the relative positions of the main fastener 19 and the secondary fastener 20 are locked. At this time, the fixation of the upper arm band 2 is completed.

[0048] After completing the fixation of the upper arm strap 2, the patient pulls the main body 1 upwards and feels the main body 1 pulling the patient's left arm upward through the upper arm strap 2 and the upper arm part 101. When the force to move the left arm upward reaches the appropriate size, stop lifting the main body 1 and make the main body 1 fit to the left shoulder. Then the patient turns the tightening piece 12, and the tightening piece 12 pulls the drawstring 10 to move. Finally, the drawstring 10 and the fastening belt 3 are both in a taut state. Then the patient continues to turn the tightening piece 12 until the tightening force of the drawstring 10, the fastening belt 3 and the main body 1 on the patient reaches the appropriate size. At this time, stop turning the tightening piece 12 and adjust the position of the connecting piece 8 according to the force state of the fastening belt 3 so that the tightening forces on the patient on the upper and lower sides of the fastening belt 3 tend to be consistent. At this time, the shoulder support is worn.

[0049] When the shoulder support is worn for a long time, as the patient's left arm moves, the upper arm strap 2 will move upward relative to the patient's left arm, resulting in a reduced lifting effect of the shoulder support on the patient's left arm. At this time, the patient only needs to pull the locking piece 21 toward the lower side of the secondary fastener 20, so that the unlocking portion 212 contacts the two fastening teeth 201 and squeezes the two fastening teeth 201 to move towards each other, so that the fastening teeth 201 release the limit on the adjacent fastening bevel 191. At this time, the upper arm portion 101 is reset and the fastening rope 18 is pulled by the edge elastic strip 14 to move. The main fastener 19 and the secondary fastener 20 move backward under the traction of the fastening rope 18, so that the tightening force of the upper arm strap 2 and the upper arm strap 101 on the patient's left arm is reduced. Then the patient presses the tightening piece 12 to release the pull rope 10 of the tightening piece 12, and the patient pulls the upper arm strap 2 and the upper arm strap 101 downward together. The upper arm band 2 and the upper arm portion 101 roughly form a cylinder under the action of the elastic sheet 17, which is convenient for the patient to pull the upper arm band 2 and the upper arm portion 101 downward (to avoid the lower portion of the upper arm band 2 and the upper arm 101 curling up during the process of the patient pulling the upper arm band 2 and the upper arm 101 downward). Then repeat the above steps to restore the tightening force of the upper arm band 2 and the upper arm 101 on the patient's left arm, and restore the tightening force of the drawstring 10, the fastening belt 3 and the main body 1 on the patient's chest. When the patient needs to take off the shoulder support, he only needs to repeat the above steps of pulling the locking member 21 toward the lower side of the secondary fastener 20 to reduce the tightening force of the upper arm portion 101 and the upper arm band 2 on the patient's arm, and then separate the upper arm band 2 from the connecting buckle 4, repeat the above steps of pressing the tightening member 12 to make the tightening member 12 release the drawstring 10, so that the tightening force of the drawstring 10, the fastening belt 3 and the main body 1 on the patient's chest is reduced, and the shoulder support can be taken off at this time.
