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 one-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 support 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 rest usually consists of a chest strap, a main body and an upper arm strap. When wearing the shoulder rest, the upper arm strap needs to be fixed first, and then the shoulder rest main body is pulled upward, and the chest strap is connected to the shoulder rest main body at the same time. Since the lifting of the shoulder rest main body and the fixing of the chest strap to the main body need to be performed simultaneously, existing patients cannot wear the shoulder rest by themselves and can only rely on family members or caregivers to wear the shoulder rest for the patients, which makes the existing shoulder rest inconvenient to use.

For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0019] 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 used to illustrate the patient's left shoulder dislocation.

[0020] A shoulder fixation device for orthopedic rehabilitation, see Figure 1-Figure 5 , comprising: a main body 1, an upper arm portion 101 is arranged on the main body 1, an upper arm band 2 is fixedly connected to the upper arm portion 101, a fastening band 3 is fixedly connected to the main body 1, a connecting buckle 4 is fixedly connected 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 fixedly connected to the upper arm band 2 to provide support for the patient's upper arm; a velvet surface 6 is fixedly connected to a position of the upper arm band 2 close to the airbag 5, and a hook surface 7 is fixedly connected to the position of the upper arm band 2 away from the airbag 5, and the hook surface 7 contacts The suede surface 6 is in contact and matched; the connecting piece 8 is fixedly connected to the end of the fastening belt 3 away from the main body 1; the sleeve 9 is fixedly connected to the main body 1, the sleeve 9 is fixedly connected with a drawstring 10, and a sliding sleeve 11 is fixedly connected 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 band 2 and the fastening belt 3 are all made of polyester-cotton blended material, so that the above three have both elasticity and breathability.

[0021] In the above scheme, the fixing action and the lifting action of the shoulder support are separated, 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 different in length around the patient's upper body, 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, the 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, 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.

[0022] The tightening piece 12 is an existing element (similar to the existing knob-type shoelace tightening system). The drawstring 10 can be wound up by rotating the tightening piece 12, and the drawstring 10 can be released with one click by pressing the tightening piece 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 the device winds up the drawstring 10 through the tightening piece 12, the drawstring 10 moves by pulling the fastening belt 3 through the connecting piece 8. When the tightening force of the fastening belt 3 on the patient reaches a suitable value, the tightening piece 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 piece 8 on the drawstring 10 is changed, so as to change the pulling force of the drawstring 10 on the upper and lower sides of the connecting piece 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.

[0023] 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.

[0031] 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 rest, so as to adjust the position of the shoulder rest; 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 to prevent the upper arm band 2 from folding, so that the upper arm band 2 can remain 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 to maintain the shape of the upper arm 101.

[0032] 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 .

[0033] In the above scheme, it is intended to prevent the upper arm band 2 from being folded between the upper arm portion 101 and the patient's left arm when the main body 1 is worn; 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.

[0034] See also Figure 6-Figure 8 , and also includes: two fastening ropes 18, both fixedly connected to the two edge elastic strips 14; a main fastener 19, fixedly connected to the fastening rope 18 on one side, and a plurality of fastening bevel grooves 191 are arranged in the main fastener 19, and the fastening rope 18 on the other side is fixedly connected 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.

[0035] In the above scheme, it is intended to adjust the tightening force of the upper arm part 101 and the upper arm band 2 on the patient's left arm; two grooves are arranged 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 part 101 and the upper arm band 2 is reduced, thereby improving the tightening force of the upper arm part 101 on the patient's left arm.

[0036] See also Figure 8 and Fig. 9 , and also includes: a locking member 21, which is limitedly slidably connected in 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 pressed and matched with the fastening tooth 201.

[0037] In the above scheme, the locking member 21 is used 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, and 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 groove 191.

[0038] When wearing the device, the patient first passes the right arm and head through the "ring" formed by 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 both 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.

[0039] 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 clips the upper arm belt 2 into the connecting buckle 4, and makes the hook surface 7 fit 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), and the patient presses the main fastener 19 into the secondary fastener 20, and the fastening teeth 201 contact with the adjacent fastening bevel grooves 191 in turn, and the main fastener 19 is pushed into the secondary fastener 20. Move, pulling the fastening rope 18 to move, and 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 position of the main fastener 19 and the secondary fastener 20 is locked. At this time, the fixation of the upper arm band 2 is completed.

[0040] 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 upwards through the upper arm strap 2 and the upper arm part 101. When the force for moving the left arm upward reaches an 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 an 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 of the upper and lower sides of the fastening belt 3 on the patient tend to be consistent. At this time, the shoulder support is worn.

[0041] 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, causing the shoulder support to reduce the lifting effect of the patient's left arm. At this time, the patient only needs to pull the locking piece 21 to 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 limitation 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 backwards under the traction of the fastening rope 18, so that the tightening force of the upper arm strap 2 and the upper arm portion 101 on the patient's left arm is reduced. Then the patient presses the tightening piece 12 to release the drawstring 10, and the patient pulls the upper arm strap 2 and the upper arm 101 downward together, and the edge elastic strip 14, the groove elastic strip 15, and the second elastic strip 16 Under the action of the elastic sheet 17, the upper arm band 2 and the upper arm part 101 roughly form a cylinder, which is convenient for the patient to pull the upper arm band 2 and the upper arm part 101 downward (to avoid curling of the lower part of the upper arm band 2 and the upper arm part 101 during the process of the patient pulling the upper arm band 2 and the upper arm part 101 downward), and then repeat the above steps to restore the tightening force of the upper arm band 2 and the upper arm part 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 piece 21 toward the lower side of the secondary fastener 20 to reduce the tightening force of the upper arm part 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 piece 12 to make the tightening piece 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.
