Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a lumbar support. Background Technology

[0002] Medical staff stand for more than 8 hours a day and bend over 40 times a day, resulting in a 3-5 times higher incidence of lumbar spine diseases compared to the general population. Existing lumbar support products only provide static support and cannot meet the needs of dynamic work scenarios, while traditional folding chairs are bulky and cannot be carried around, forcing medical staff to bend over even during emergency treatments.

[0003] Bending over for extended periods keeps the lumbar muscles in a state of constant tension and contraction, like a continuously stretched spring. Over time, this leads to fatigue, soreness, and muscle strain. Normally, the intervertebral discs in the lumbar spine maintain their function under a certain amount of pressure. When bending over, especially excessively or with heavy loads, the pressure on the intervertebral discs increases significantly. Over time, this excessive pressure can cause the annulus fibrosus of the intervertebral disc to wear down and tear.

[0004] As the annulus fibrosus of the intervertebral disc is damaged, the nucleus pulposus inside may break through the confines of the annulus fibrosus and protrude posteriorly, compressing surrounding nerve tissue and causing lumbar disc herniation. When bending over, the pressure on the intervertebral disc increases, which further aggravates the compression of the nerve, leading to symptoms such as lower back pain, radiating pain in the lower limbs, and numbness.

[0005] Ligaments in the lumbar region, such as the supraspinous ligament and interspinous ligament, play a crucial role in maintaining the stability of the lumbar spine. These ligaments are stretched when bending over. Excessive or frequent bending can lead to ligament strain, laxity, or even rupture, affecting the stability of the lumbar spine and causing lower back pain and limited mobility.

[0006] The facet joints of the lumbar spine are also subjected to pressure and friction when bending over. Long-term bending or sudden bending over may lead to misalignment of the facet joints, synovial impingement, etc., causing lumbar facet joint disorder and symptoms such as lower back pain that worsens with activity.

[0053] like Figure 1-10The lumbar support shown includes a fixing part 1, a protective part 2, a connecting part 3, a seating part 4, and a support part 5. One side of the protective part 2 is fixedly connected to the fixing part 1, and the other end is hinged to the connecting part 3. The seating part 4 includes a first seat plate 41 and a second seat plate 42. One end of the first seat plate 41 is hinged to the connecting part 3, and the other end is hinged to the second seat plate 42. The support part 5 is hinged to the seating part 4. The fixing part 1 is used to bind the user's waist. When the user is standing, it provides external support for the lumbar spine, helps maintain the normal physiological curvature of the lumbar spine, reduces the pressure on the lumbar spine during daily activities, prevents excessive forward or backward curvature of the lumbar spine, and avoids excessive stretching or tension of the lumbar muscles and ligaments due to changes in the shape of the lumbar spine.

[0054] It has a folded-out state and an unfolded state; in the folded-out state, the connecting part 3, the seating part 4, and the support part 5 are all folded and stored for easy carrying. At this time, the first end face of the connecting part 3 abuts against the protective part 2, and the second end face abuts against the first seat plate 41; the side of the first seat plate 41 away from the connecting part 3 abuts against the second seat plate 42; the support part 5 is located between the first seat plate 41 and the second seat plate 42.

[0055] When unfolded, the connecting part 3, the seating part 4, and the support part 5 unfold to form a chair. At this time, the second end face of the connecting part 3 abuts against the protective part 2; the first seat plate 41 and the second seat plate 42 form a plane; the support part 5 is located on the side of the seating part 4 away from the connecting part 3. The protective part 2 and the connecting part 3 form the backrest, the seating part 4 unfolds to form the seat, and the support part 5 unfolds to form the legs. At this time, the user can sit down to operate, effectively avoiding lumbar spine injury caused by bending over.

[0056] Preferably, a buffer layer is provided on the side of the protective part 2 away from the connecting part 3, the purpose of which is to enhance the user's comfort.

[0057] Preferably, the fixing part 1 includes a strap; the two ends of the strap are detachably connected; when the two ends of the strap are connected, the strap is wrapped around the user's waist.

[0058] Preferably, a moisture-absorbing layer is provided on the side of the strap away from the protective part 2. The function of the moisture-absorbing layer is to absorb the sweat produced by the user's waist during the wearing of the lumbar support, so as to prevent bedsores from developing on the user's waist due to prolonged use.

[0059] The side of the protective part 2 away from the connecting part 3 is a recessed protective part 2. When the user wears the waist support, the user's back will come into contact with the protective part 2 on the protective part 2, further enhancing the user's comfort.

[0060] like Figure 1-4As shown, the support part 5 includes a first support unit and a second support unit; the first support unit is hinged to the first seat plate 41; the second support unit is hinged to the second seat plate 42; when in the unfolded state, the first seat plate 41 and the second seat plate 42 form a plane, and the first support unit and the second support unit fold away from the seating part 4 to form chair legs to support the seating part 4.

[0061] Specifically, the first support unit and the second support unit have the same structure.

[0062] Specifically, the total number of the first support unit and the second support unit is greater than or equal to 3, so as to fix and support the seating part 4.

[0063] like Figure 1-4 As shown, the first support unit has a first rotating joint inside. When in the storage state, the first support unit is folded and stored through the first rotating joint.

[0064] like Figure 1-4 As shown, the second support unit has a second rotating joint inside. When in the stowed state, the second support unit is folded and stowed away via the second rotating joint.

[0065] like Figure 5-6 As shown in Figure 10, the first support unit includes a first support leg 51 and a second support leg 52; one end of the first support leg 51 is hinged to the first seat plate 41, and the other end is hinged to the second support leg 52; the first seat plate 41 is provided with a first guide surface; a positioning block 511 is provided at the end of the first support leg 51 away from the first seat plate 41.

[0066] When in the unfolded state, the side wall of the first support leg 51 abuts against the first guide surface, creating an angle of less than 90° between the first support leg 51 and the first seat plate 41; the side wall of the second support leg 52 abuts against the positioning block 511; and the axis of the first support leg 51 is parallel to the axis of the second support leg 52. When a user sits on the seating section 4, the pressure exerted by the user on the seating section 4 causes the first and second support units to bend to opposite sides, pressing the side wall of the first support leg 51 against the first guide surface and simultaneously pressing the side wall of the second support leg 52 against the positioning block 511. At this time, the pressure applied by the user to the support section 5 prevents the first support unit from folding along the first rotation joint and the second support unit from folding along the second rotation joint, thus maintaining the posture of the support section 5 for a long time.

[0067] Preferably, the second support leg 52 has a groove inside; when in the retracted state, the first support leg 51 enters the groove. The purpose of this design is to reduce the volume occupied by the support part 5 when in the retracted state.

[0068] like Figure 5-6As shown in Figure 10, a first limiting frame 412 is provided on the first seat plate 41; a second limiting frame 422 is provided on the second seat plate 42; the first limiting frame 412 is detachably connected to the first support unit; the second limiting frame 422 is detachably connected to the second support unit. In the folded state, the positioning block 511 of the first support unit is installed inside the first limiting member, and the positioning block 511 of the second support unit is installed inside the second limiting member. During user movement, this prevents the first and second support units from shifting, thus preventing the seating section 4 from accidentally opening.

[0069] like Figure 5-6 As shown, the first seat plate 41 is provided with a first limiting block; the second seat plate 42 is provided with a second limiting block; when in the unfolded state, the limiting block and the second limiting block abut against each other; so that the first seat plate 41 and the second seat plate 42 form a plane.

[0070] Specifically, the first limiting block is located on both sides of the first seat plate 41; the second limiting block is located on both sides of the second seat plate 42. When in the retracted state, the first seat plate 41, the second seat plate 42, the first limiting block, and the second limiting block form a cavity, and the first support unit and the second support unit are housed inside this cavity.

[0071] like Figure 5-6 As shown in Figures 1 and 10, the first seat plate 41 is provided with a first rotating bracket 411; the first rotating bracket 411 is hinged to the first support unit; the second seat plate 42 is provided with a second rotating bracket 421; the second rotating bracket 421 is hinged to the second support unit.

[0072] like Figure 3 , 9 As shown, a rotating groove is provided on one side of the first seat plate 41; a rotating shaft is provided inside the rotating groove; one end of the connecting part 3 is inserted into the rotating groove and connected to the rotating shaft. When in the unfolded state, the side wall of the connecting part 3 abuts against the inner wall of the rotating groove to maintain the posture between the connecting part 3 and the first seat plate 41.

[0073] Specifically, one end of the connecting part 3 is provided with a rotating frame; the rotating frame protrudes from the side wall of the connecting part 3; after the rotating frame is inserted into the interior of the rotating groove, it is connected to the rotating shaft.

[0074] like Figure 1-9 As shown, a limiter 43 is provided at the end of the second seat plate 42 away from the first seat plate 41; the limiter 43 is detachably connected to the protective part 2.

[0075] Specifically, the limiter 43 is hinged to the second seat plate 42; the protective part 2 is provided with a mounting hole; the end of the limiter 43 away from the second seat plate 42 is detachably connected to the mounting hole. When in the retracted state, the limiter 43 is inserted into the interior of the mounting hole.

[0076] Preferably, the protective part 2 has a mounting groove at the end away from the fixing part 1; one end of the connecting part 3 is inserted into the mounting groove.

[0077] Preferably, the connecting part 3 is detachably connected to the mounting groove; when in the storage state, the connecting part 3 enters the interior of the mounting groove.

[0078] The unfolding method in this embodiment:

[0079] 1. Disconnect the limit switch 43 from the protective part 2;

[0080] 2. Fold the second seat plate 42 to expose the first support unit and the second support unit;

[0081] 3. Disconnect the first limiting frame 412 from the first support unit and the second limiting frame 422 from the second support unit;

[0082] 4. Fold the first seat panel 41 and the connecting part 3 to form the chair back and the seat surface;

[0083] 5. Rotate the first support leg 51 and the second support leg 52 to both sides to form chair legs;

[0084] 6. The user sits down.

[0085] The storage method in this embodiment:

[0086] 1. The user stands up.

[0087] 2. Rotate the first support leg 51 and the second support leg 52 towards the center, connect the first limiting frame 412 to the first support unit, and connect the second limiting frame 422 to the second support unit to fold up the chair legs.

[0088] 3. Fold up the first seat panel 41 and the second seat panel 42 to retract the seat surface;

[0089] 4. Fold up the connecting part 3 to fold up the chair back;
